PART I

ITEM 1. BUSINESS

Description of business

We are a facilities-based provider of low-cost, high-speed Internet access, private network services, optical wavelength and optical transport services and data center colocation space and power. Our network is specifically designed and optimized to transmit packet-routed data. We deliver our services primarily to businesses, large and small, communications service providers and other bandwidth-intensive organizations in 56 countries across North America, Europe, South America, Oceania and Africa. We are a Delaware corporation and headquartered in Washington, DC.

We offer on-net Internet access services exclusively through our own facilities, which run from our network to our customers’ premises. We offer our on-net services to customers located in buildings that are physically connected to our network. As a result, we are not dependent on local telephone companies or cable TV companies to serve our customers for our on-net Internet access and private network services. Our on-net service consists of high-speed Internet access and private network services offered at speeds ranging from 100 megabits per second to 400 gigabits per second.

We provide our on-net Internet access and private network services to our corporate, net-centric and enterprise customers. Our corporate customers are located in multi-tenant office buildings that typically include law firms, financial services firms, advertising and marketing firms, as well as health care providers, educational institutions and other professional services businesses. Our net-centric customers include bandwidth-intensive users that leverage our network either to deliver content to end users or to provide access to residential or commercial Internet users. Content delivery customers include over the top media service providers, content delivery networks, web hosting companies, and commercial content and application software providers. Our net-centric customers include access networks comprised of other internet service providers (“ISP’s”), telephone companies, mobile phone operators and cable television companies that collectively provide internet access to a substantial number of broadband subscribers and mobile phone subscribers across the world. These net-centric customers generally receive our services in carrier neutral colocation facilities and in our own data centers. We operate data centers throughout North America and Europe that allow our customers to collocate their equipment and access our network. Additionally, the Sprint Business (as defined below) customers include a number of companies larger than our historical customer base. In connection with the acquisition of Sprint Communications, we expanded selling services to these larger “Enterprise” customers.

In addition to providing on-net services, we provide Internet access and private network services to customers that are not located in buildings directly connected to our network. We provide these off-net services primarily to corporate customers using other carriers’ circuits to provide the “last mile” portion of the link from the customers’ premises to our network. We also provide certain non-core services that resulted from acquisitions, including the acquisition of Sprint Communications (as discussed below). We continue to support but do not actively sell these non-core services.

In connection with our acquisition of Sprint Communications, we began to provide optical wavelength services and optical transport services over a network that is generally independent of our legacy IP network. We are selling these wavelength services to our existing customers, customers of Sprint Communications and to new customers who require dedicated optical transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure.

Acquisition of the Sprint Business

On May 1, 2023 (the “Closing Date”), Cogent Infrastructure, Inc., (now Cogent Infrastructure, LLC), a Delaware corporation and our direct wholly owned subsidiary (the “Buyer” or “Cogent Infrastructure”), closed on its acquisition of the U.S. long-haul fiber network (including the non-U.S. extensions thereof) of Sprint Communications and its Subsidiaries (the “Sprint Business”) in accordance with the terms and conditions of the Membership Interest Purchase Agreement (the “Purchase Agreement”), dated September 6, 2022, by and among us, Sprint Communications LLC, a Kansas limited liability company (“Sprint Communications”) and an indirect wholly owned subsidiary of T-Mobile US, Inc., a Delaware corporation (“T-Mobile”), and Sprint LLC, a Delaware limited liability company and an indirect wholly owned subsidiary of T-Mobile (the “Seller”). On the Closing Date, we purchased from the Seller all of the issued and outstanding membership interests (the “Purchased Interests”) of Wireline Network Holdings LLC, a Delaware limited liability company that, following an internal restructuring and divisive merger, holds Sprint Communications’ assets and liabilities relating to the Sprint Business (such transactions contemplated by the Purchase Agreement, collectively, the “Transaction”).

Page 4 of 96

Corporate Structure after the Closing Date

The Company operates through its two direct, wholly owned subsidiaries, Cogent Infrastructure and Cogent Communications Group, LLC (“Cogent Group”).

Cogent Infrastructure holds the Sprint Business operations. Following the Closing Date, Cogent Infrastructure, through its subsidiaries, owned, among other things, the Sprint Network (as defined below), consisting of approximately 20,800 route miles of owned fiber optic cable in the continental United States, a portfolio of owned and leased properties totaling approximately 1.9 million square feet, Sprint operating subsidiaries in over 30 countries worldwide, approximately 1,300 Sprint customers, both enterprise and net-centric, vendor and supply agreements and 9.9 million IPv4 addresses.

On May 2, 2024, Cogent IPv4 LLC (the “IPv4 Issuer”), a special-purpose, bankruptcy remote, indirect wholly owned subsidiary of the Company, issued $206.0 million aggregate principal amount of 7.924% IPv4 Notes (the “IPv4 Notes”), with an anticipated term ending in May 2029 (such anticipated repayment date, the “ARD”), in an offering exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”).

Cogent Group is the parent of Cogent Communications, LLC (formerly Cogent Communications, Inc.), which was our sole operating company prior to the Closing Date, and Cogent Group is the issuer of our $500.0 million of 3.50% senior secured notes due in May 2026 (“2026 Notes”) and our $750.0 million of 7.00% senior unsecured notes due in June 2027 of which $450.0 million were issued in June 2022 (“2027 Notes”) and $300.0 million were issued in June 2024 (“2027 Mirror Notes”). Cogent Group owns, among other things, our indefeasible-right-of-use (“IRU”) network, Cogent data centers, Cogent operating subsidiaries in 56 countries worldwide, our corporate and net-centric customer base and over 25 million IPv4 addresses. Cogent Group also receives payments due from T-Mobile for IP transit services in connection with the Transaction.

We have moved and may continue to move, to the extent permitted by and in compliance with the indentures governing our 2026 Notes, 2027 Notes, 2027 Mirror Notes and IPv4 Notes, certain assets and obligations between the companies owned by Cogent Infrastructure and Cogent Group to better align these assets and obligations with our business and operations and for general corporate purposes.

Competitive Advantages

We believe we address many of the data communications needs of businesses large and small, communications service providers and other bandwidth-intensive organizations by offering them high-quality, high-speed Internet access and private network services at attractive prices. After our acquisition of the Sprint Business, we began offering services to larger enterprise customers. We believe that our organization has the following competitive advantages:

Low Cost of Operation: We believe that the wireline telecom industry is undergoing, and will continue to face, significant price deflation for its applications and services. This price deflation is a result of a variety of factors including increased competition, enhanced substitutability of certain products and services and the continued impact of Moore’s Law, which has driven down the cost of technology, particularly for fiber optic Wavelength Division Multiplexing equipment and optically interfaced routers. Faced with the backdrop of continued price deflation in our industry, we have made a series of discreet choices around our network design, operating strategy and product offerings that are consistent with our objective of becoming the low-cost operator in our industry. Since our initiation of operations, this strategy has resulted in a rapid decline in our cost to transmit bits, which has increased our margins and decreased our capital intensity as measured by our capital expenditures per total revenues. Important components of our low-cost operating strategy include:

Page 5 of 96

Greater Control and Superior Delivery. Our on-net service does not rely on circuits that must be provisioned by a third-party carrier. In our on-net MTOBs, we provide our customers the entire network, including the “last mile” and the in-building fiber optic connections to our customer’s suite. In our CNDCs, we are collocated with our customers. As a result, only a cross-connection within the data center is required to provide our services to our customers, including our newer optical wave and optical transport offerings. The structure of our on-net service provides us with more control over our service, quality and pricing. It also allows us to provision services more quickly and efficiently than provisioning services on a third-party carrier network. The vast majority of our on-net Internet and VPN services can be installed in less than two weeks, which is materially faster than the installation times for some of our incumbent competitors.

High-Quality, Reliable Service. We are able to offer high-quality Internet service due to our network design and composition. We believe that we deliver a high level of technical performance because our network is optimized for packet routed traffic. Its design increases the speed and throughput of our network and reduces the number of data packets dropped during transmission compared to traditional circuit-switched networks. We believe that our network is more reliable and carries traffic at lower cost than networks built as overlays to traditional circuit-switched, or TDM networks.

Page 6 of 96

Large Addressable Market. We have systematically evaluated and chosen our network extensions to buildings, data centers and markets based upon a rigorous set of criteria to evaluate the economic opportunity of network locations. Additional factors relevant to our pursuit of new buildings include the willingness of building owners to grant us access rights, the availability of optical fiber networks to serve those buildings, the costs to connect buildings to our network and equipment availability. We have also begun to evaluate the sustainability of new locations by evaluating the LEED Green Rating of Buildings, the potential to source renewable energy at locations and the potential impact of climate change on a location including proximity to water and the risk of flooding. Our network is connected to 3,453 total buildings located in 264 metropolitan markets globally. These buildings include 1,871 large MTOBs (totaling over 1.0 billion square feet of office space) in major North American cities where we offer our services to a diverse set of high-quality corporate customers within close physical proximity of each other. These buildings also include 1,646 CNDCs located in 1,478 buildings in North America, Europe, South America, Oceania and Africa where our net-centric customers directly interconnect with our network and 55 Cogent edge data centers. We also operate 104 of our own data centers 48 of which were converted from facilities acquired with the Sprint Business) across the United States and in Europe, which comprise over 1.9 million square feet of floor space, offer 177 MW of power and are directly connected to our network. We believe that these network points of presence strategically position our network to attract high levels of Internet traffic and maximize our revenue opportunities and profitability.

Balanced, High-Traffic IP Network. Since its inception, our network has grown significantly in terms of its geographic reach, customer connections, and traffic. We currently serve 8,250 access networks as well as numerous large and small content providers and 47,371 corporate customer connections and 14,776 enterprise customer connections. Because of these bases of customers who distribute (content providers) and receive (access networks) content on our network, we believe that the majority of all the traffic remains “on-net” by both originating and terminating on our network. This control of traffic is an important differentiator as it increases our service reliability and speed of traffic delivery. The increasing share of traffic delivered from content providers to access networks also enhances our margins as we are compensated by both the originating customer and the terminating customer. The breadth of our network, extensive size of our customer base, and the volume of our traffic enables us to be one of a handful of Tier 1 networks that are interconnected on a settlement-free basis. This Tier 1 network peering status broadens our geographic delivery capability and materially reduces our network costs.

Proven and Experienced Management Team. Our senior management team is composed of seasoned executives with extensive expertise in the telecommunications industry as well as knowledge of the markets in which we operate. The members of our senior management team have an average of over 20 years of experience in the telecommunications industry and many have been working together at the Company for several years. Several members of the senior management team have been working together at the Company since 2000. Our senior management team has designed and built our network and, during our formative years, led the integration of network assets we acquired through 13 significant acquisitions prior to our acquisition of the Sprint Business and managed the expansion and growth of our business. A number of the members of senior management who joined us as part of our acquisition of the Sprint Business have similar experience and tenure in both the telecommunications industry and at the Sprint Business. We anticipate that our management team will successfully manage the integration of the Sprint Business into our current operations.

Our Strategy

We intend to remain a leading provider of high-quality, high-speed Internet access and private network services and to continue to improve our profitability and cash flow. The principal elements of our strategy include:

Grow our Corporate Customer Base. Our on-net corporate customers are typically small to medium-sized businesses connected to our network through MTOBs or connected to our network through one of our on-net CNDCs. We generally sell two types of services to our corporate customers: dedicated internet access and private network services. We typically sell dedicated internet access at the same price per connection as our competitors, but our customers benefit from our significantly faster speeds and rapid installation times. These customers are increasingly integrating off-site data centers and cloud services into their IT infrastructure in order to take advantage of the safety, security and redundancy that is offered by locating company processing power, storage and software at a data center. An important part of this new infrastructure is a high-speed, dedicated internet connection from the corporate premises to the data center and the Internet and from one corporate premises to other corporate premises. We believe that the importance of data centers will increasingly lead tenants to reconfigure their communications infrastructure to include dedicated internet access across their locations.

Page 7 of 96

Expand our Business with Enterprise Customers. With our acquisition of the Sprint Business, we acquired a number of larger enterprise customers. While we are in the process of terminating certain non-core services to these customers at the end of their current term, we have continued to provide our core services to enterprise customers and elected to provide MPLS based VPN as well as VPLS services, a new service for the Company, as well. We have not previously focused our sales efforts on larger enterprise customers. Since the acquisition of the Sprint Business, we have formed dedicated sales teams who are tasked with preserving existing business with and seeking new sales from enterprise customers.

Increase our Share of the Net-Centric Market. We are currently one of the leading providers of high-speed internet access to a variety of content providers and access networks across the world. We intend to further load our high-capacity network as a result of the growing demand for high-speed Internet access generated by these types of bandwidth-intensive applications such as over-the-top media services, online gaming, video, Internet of Things, voice over IP, remote data storage, and other services. We expect that we will continue to grow our shares of these segments by offering our customers a series of attractive features including:

Pursue On-net Customer Growth. Our high-capacity network provides us with the ability to add a significant number of customers to our network with minimal direct incremental costs. We intend to increase usage of our network and operational infrastructure by adding customers in our existing on-net buildings, as well as developing additional markets and connecting more MTOBs and CNDCs to our network. We are also upgrading our network and operational infrastructure to provide wave and optical transport services in more of our on - net buildings. We emphasize our on-net services because they generate greater profit margins and we have more control over service levels, quality and pricing, and our on-net services are provisioned in considerably less time than our off-net services. Our fiber network connects directly to our on-net customers’ premises and we pay no local access (“last mile”) charges to other carriers to provide our on-net services.

Continue to Improve our Sales Efforts and Productivity. A critical factor in our success has been our investment and focus on our sales and marketing efforts. We seek to maintain a consistent level of sales productivity as measured by the number of connections sold per salesperson per month, considering adjustments to the changing mix of products sold and installed. In order to gain market share in our targeted businesses, we expect to continue our sales efforts including introducing strategies and tools to optimize and improve our sales productivity. We also intend to leverage the skills and relationships of our sales force to sell new service offerings, in particular, optical wavelength and optical transport services. We have developed several training programs that are directed toward increasing our sales representative tenure and increasing our sales representative productivity. In addition, we have required all of our employees to work in the office on a full-time basis, thereby providing additional opportunities for management coaching and oversight in order to increase productivity.

Expand our Off-net Corporate and Enterprise Internet Access and VPN Business. We have agreements with over 700 national and international carriers providing us last mile network access to over 6 million commercial buildings that are lit by fiber optic cable in the countries we serve and that are not currently served by our network. We believe these agreements broaden our addressable market for corporate dedicated Internet access and private network services and enhances our competitive position through the ability to provide enterprise-wide connectivity for corporate customers. In order to take advantage of this large set of commercial buildings, we have developed an automated process to enable our salesforce to identify opportunities in the off-net market for dedicated Internet access and private network services and to quickly offer pricing proposals to potential customers. We continue to negotiate reduced pricing under our numerous carrier agreements that enable us to reduce our cost of off-net services, which enhances our competitive position in the marketplace.

Page 8 of 96

Expand our Product Offerings to Include Wavelength - Optical Transport Services. In connection with our acquisition of the Sprint Business, we expanded our offerings of optical wavelength - optical transport services over our fiber network. We are selling these services to our existing customers, customers acquired with the Sprint Business and to new customers who require dedicated optical transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure. We currently offer wavelength services in 808 data centers in the United States, Mexico and Canada. We believe our wavelength service has the advantages of unique routes, ubiquitous service locations, faster provisioning times and lower prices.

Expand our Data Center Footprint. We currently operate 104 of our own data centers across the United States and Europe. As part of our acquisition of the Sprint Business, we acquired multiple Sprint facilities that previously housed Sprint equipment. We evaluated the suitability of these facilities for conversion to commercial data center space and began repurposing suitable facilities. Repurposing these facilities included removing unused, obsolete equipment and racks, and upgrading or installing new HVAC systems, uninterruptable power supplies (“UPS”), backup generators and fire suppression systems as well as other structural changes. By December 31, 2024, we had converted the former Sprint facilities into 48 Cogent data centers and 55 Cogent edge data centers. In connection with this conversion process, we expect to decommission certain legacy Cogent data centers.

Increase our Leasing of IPv4 Address Space. We lease IPv4 address space to our customers, both on a standalone basis and as a complement to a customer’s Internet access services with us. We provide a small number of free IPv4 addresses to our dedicated Internet access customers as well. We currently own approximately 38 million IPv4 addresses, of which 9.9 million were recently acquired at the closing of the Sprint Business acquisition. We currently lease 13.0 million of our IPv4 addresses to our customers on contracts with service terms ranging from one month to five years. We intend to continue to lease IPv4 addresses to our customers as well as explore alternatives for monetizing our IPv4 address inventory.

Our Network

Our network is comprised of in-building riser facilities, metropolitan optical networks, metropolitan traffic aggregation points and inter-city transport facilities. We believe that we deliver a high level of technical performance because our network is optimized for packet routed traffic. We believe that our network is more reliable and carries packet routed traffic at lower cost than networks built as overlays to traditional circuit-switched telephone networks.

Our network is comprised of 3,453 on-net buildings and we serve 264 metropolitan markets in North America, Europe South America, Oceania and Africa. Important strategic components of our network include:

Our network consists of owned optical fiber in the Sprint Network and leased optical fiber on a long-term basis from carriers with large amounts of unused fiber to which we directly connect our own optical equipment and Internet routers to form our optical fiber national backbone. We have expanded our network by acquiring owned and leased fiber through key acquisitions of financially distressed companies or their assets at a significant discount to their original cost. Due to our network design and acquisition strategy, we believe we are positioned to grow our revenue and increase our profitability with incremental capital expenditures.

Page 9 of 96

Inter-city Network.

Our inter-city network consists of optical fiber, including transoceanic capacity circuits for undersea portions, connecting major cities in North America, Europe, South America, Oceania and Africa. Our inter-city network is comprised of the approximately 19,000-mile inter-city portion of the Sprint Network and long-term, leased strands of optical fiber, typically two to four, out of the multiple fibers owned from various dark fiber vendors. We install the optical and electronic equipment necessary to amplify, regenerate, and route the optical signals along this network. We maintain, repair, upgrade and replace the Sprint Network and we pay our dark fiber vendors our annual pro rata fees for these same services, often called “operation and maintenance” for the leased optical fiber. For both the owned and leased portions of our fiber network, we provide our own equipment maintenance.

Intra-city Networks.

In each metropolitan area in which we provide our high-speed on-net Internet access services, our backbone network is connected to one or more routers that are connected to one or more of our metropolitan optical networks. Our intra-city networks are a combination of the 1,300 miles of owned Sprint Network and our IRU rights to use optical fiber that we obtained from carriers with optical fiber networks in those cities. These metropolitan networks consist of optical fiber that runs from the central router in a market into routers located in our on-net buildings. Our metropolitan fiber runs in a ring architecture, which provides redundancy so that if the fiber is cut, data in our IP network can still be transmitted to the central router by directing traffic in the opposite direction around the ring. The router in the building provides the connection to each of our on-net customers.

Within the cities where we offer our off-net Internet access services, we lease lit circuits from telecommunications carriers, primarily local telephone companies and cable TV companies, to provide the “last mile” connection to our customer’s premises. Typically, these circuits are aggregated at various locations in those cities onto higher-capacity leased circuits that ultimately connect the local aggregation router to our network.

Multi-Tenant Office Buildings. We have network access to a portfolio of 1,871 MTOBs which provide us access to a highly attractive base of bandwidth intensive tenants. In MTOBs where we provide service to multiple tenants, we connect our routers to a cable typically containing 12 to 288 optical fiber strands that run from our equipment that is generally located in the basement of the building through the building riser to the customer location. Our service is initiated by connecting a fiber optic cable from our customer’s local area network in its suite to the infrastructure in the building riser giving our customer dedicated and secure access to our network using an Ethernet connection. We believe that Ethernet is the lowest cost network connection technology and is almost universally used for the local area networks that businesses operate.

Carrier Neutral Data Centers. Our network is collocated in and can provide connectivity to customers in 1,646 CNDCs located in 1,478 buildings across our footprint. CNDCs are an integral component of the Internet infrastructure where content providers, application service providers, carriers and corporate customers locate their server and service infrastructure. CNDCs offer highly reliable, secure, cost effective and convenient space for these operators to access important services including connectivity, power, rack space and security all on a 24-hour basis in order to support their Internet activities, and after our acquisition of the Sprint Business, wavelength services. We believe we are connected to more CNDCs than any other IP transit provider, enabling us to offer greater coverage, more network configuration choices and increased reliability for our net-centric customers. We operate an intra-city fiber network to CNDCs optimized for IP services and optical wavelength services in the US and Mexico.

Cogent Data Centers. We operate 104 data centers across the United States and in Europe. These facilities comprise over 1.9 million square feet of floor space with 177 MW of available power and are directly connected to our network. We also operate 55 Cogent edge data centers. Each location is equipped with secure access, UPS, and backup generators. Our customers typically purchase bandwidth, rack space, and power within these facilities.

Internetworking. The Internet is an aggregation of interconnected networks. Larger ISPs exchange traffic and interconnect their networks by means of direct private connections referred to as private peering. We interconnect with the networks of our customers, which represent the majority of our interconnections and network traffic, through the sale of our transit services. We currently interconnect with 8,250 networks that pay us to exchange traffic as our customers. We supplement our customer network interconnections with settlement-free peering to our non-customer tier one global ISPs. We have settlement-free private peering interconnections between our network and 23 other major ISPs who are not our customers.

Page 10 of 96

Tier 1 ISP Status. We directly connect with 8,250 total networks. As a result of the size and breadth of our customer base and the extensive footprint and scale of our network, we are a Tier 1 ISP. We currently exchange traffic with 23 other Tier 1 ISPs on a settlement free basis. The remaining networks are customers whom we charge for Internet access. We believe our standing as a Tier 1 ISP provides us with a reputation for size, breadth and reliability. These relationships also reduce our cost of operating the network versus non-Tier 1 ISP peer networks who must compensate other networks in order to deliver a significant portion of their traffic.

Peering agreements between ISPs enable them to exchange traffic.Without settlement-free peering agreements, each ISP backbone would have to buy Internet access from every other ISP backbone in order for its customer’s traffic to reach and be received from customers of other ISP backbones. We are considered a Tier 1 ISP with a large customer base, and, as a result, we have settlement-free peering arrangements with other providers with which we wish to peer. We do not purchase transit services or paid peering to reach any portion of the Internet. This allows us to exchange traffic with those ISPs without payment by either party. In such arrangements, each party exchanging traffic bears its own cost of delivering traffic to the point at which it is handed off to the other party. We do not treat our settlement-free peering arrangements as generating revenue or expense related to the traffic exchanged. We do not sell or purchase paid peering on our transit network.

Network Management and Customer Care. Following our acquisition of the Sprint Business, our primary network operations centers are located in Washington, D.C., Herndon, Virginia, Overland Park, Kansas and Madrid, Spain. These facilities provide continuous operational support for our network. Our network operations centers are designed to immediately respond to any problems in our network. Our customer care call centers are located in Washington, D.C., Herndon, Virginia, Atlanta, Georgia, and Madrid, Spain. To ensure the quick replacement of faulty equipment in the intra-city and long-haul networks, we have deployed field engineers across North America and Europe. In addition, we have maintenance contracts with third-party vendors that specialize in maintaining optical and routed networks.

Field Services. Our field services organization includes over 350 employees globally. The department facilitates the deployment, maintenance, and support of products or services in our data centers, network points of presence (“PoPs”), CNDCs and MTOBs. This department is responsible for on-site activities, ranging from initial installations and configurations to troubleshooting, repairs, and upgrades. Field Services is also responsible for deployment, repair and reconfiguration of the approximately 20,800 route miles of owned fiber optic cable comprising the Sprint Network.

Our Customers

We offer our services to three sets of customers: corporate customers, which primarily include small and medium-sized businesses located in North America, enterprise customers, and net-centric customers, which include, content providers, applications service providers and access networks, comprised of ISPs, cable operators, mobile operators and phone companies located in North America, Europe South America, Oceania and Africa.

Our corporate customers primarily purchase our services from us on-net in MTOBs and CNDCs or off-net through other carriers’ “last mile” connections to those customer facilities in metropolitan markets in North America. This service enables these customers to access the Internet with a high-speed, bi-directional, symmetric circuit with a high degree of reliability and 100% access to that contractual capacity at all times. Depending upon the geographic breadth of our customers’ footprint and their communications requirements, we also sell these corporate customers private network services. Private network services provide connectivity on a point to point or point to multi-point basis. This service allows customers to connect geographically dispersed local area networks in a seamless manner. We primarily offer these corporate customers speeds ranging from 100 Mbps per second to 1 Gbps per second and in some cases up to 10 Gbps per second. The continued growth in demand for increased bandwidth has led to a rapid shift towards higher capacity circuits.

We have agreements with multiple national, international and regional carriers providing us “last mile” network access to over 6 million buildings. We believe these agreements broaden our addressable market for corporate dedicated internet access, VPN services and/or MPLS and enable us to better leverage the skills and capacity of our direct salesforce. As our sales of off-net services have increased, the pricing in our carrier agreements has commensurately decreased in light of our increased volume.

Our net-centric customers purchase our services in our 1,646 CNDCs as well as our 104 data centers and 55 Cogent edge data centers for a total of 1,805 data centers. We support these services in 264 metropolitan markets in 56 countries across the world. These bandwidth intensive organizations typically purchase circuits ranging from 10 Gbps up to 400 Gbps, designed to provide them high-speed, bi-directional, symmetric circuits with a high degree of reliability and 100% access to the contractual capacity at all times. In addition to contractual capacity, certain net-centric customers also purchase metered service that enables customers to pay for actual volume of bits delivered on a per bit per second basis. We also offer a burst product that allows net-centric customers to utilize

Page 11 of 96

capacity when they exceed their contractual capacity. The per bit charge for this burst capacity typically exceeds the rate for contractual services. Overall, we believe that, on a per megabit basis, our service offering is one of the lowest priced in the marketplace. We also offer colocation services in our data centers. This service offers Internet access combined with rack space and power in our facilities, allowing the customer to locate a server or other equipment at that location and connect to our Internet access service. We currently offer wavelength services in 808 CNDCs, in the United States and Mexico.

We began to serve enterprise customers in connection with our acquisition of the Sprint Business. We define “enterprise” customers as large corporations (typically, Fortune 500 companies or companies with greater than $5 billion in annual revenue) running Wide Area Networks with several dozen to several hundred sites. Enterprise customers generally purchase dedicated internet access, MPLS based VPN’s and other services in on-net and off-net locations. Our enterprise customers generally purchase our services on a price-per-location basis.

We offer lower prices for longer term and volume commitments. We emphasize the sale of our on-net services over our off-net services, as on-net services generate higher gross margins, and we believe we can offer faster installation and greater reliability with our on-net offering

Our People – Human Capital Management

We strive to become a leading employer in our industry by creating a workplace where employees have the tools and resources they need to hone their talents, advance in their careers and be rewarded for their hard work. We also seek to create a diverse workplace that is respectful of all employees, as we believe this is critical to fostering an employee culture that can deliver the best service in our industry to our customers. Our human capital objectives and initiatives are overseen by the Compensation Committee of our Board of Directors.

Workforce.

As of December 31, 2024, we had 1,916 employees located in 25 different countries in a variety of different roles. Approximately 88% of our employees are located in the United States, Canada and Mexico, 11% are located in Europe, 2% are located in Oceania and 0.2% in South America. As of December 31, 2024, 34% of our employees were quota-bearing sales representatives, 10% were in sales management or sales support roles and 56% were in operational or administrative functions. Unions represent 30 of our employees in France and 4 of our employees in Sweden. The employees of the Sprint Business that operate in Germany are governed by a works council. We believe that we have a satisfactory relationship with our employees.

Diversity and Inclusion. We strive to maintain a diverse and inclusive workforce everywhere we operate. We recruit the best people for the job without regard to gender, race, ethnicity or other protected traits, and it is our policy to comply fully with all domestic, foreign and local laws relating to discrimination in the workplace. At the direction of our Board of Directors, we mandated training for all of our employees on topics of diversity and inclusion. All employees are required to complete online training in unconscious bias, and managers are further required to complete additional training in inclusion. We intend to continually reinforce our commitment to global inclusion and diversity.

Employee Retention. We compete in an industry that is highly competitive for talent. Attracting, developing and retaining skilled people in sales, technical and other positions is crucial to executing our strategy and our ability to compete effectively. While we monitor overall employee retention, we focus in particular on sales representative retention with objective performance criteria, as our new sales and revenue growth are driven almost entirely by the sales generated by our direct sales force. As a complement to our sales representative retention metric, we also closely track the pace of hiring new sales representatives.

Our sales and marketing organization comprises 45% of our employees and our sales representatives comprise 34% of our employees. For the year ended December 31, 2024, we averaged a 5.7% monthly churn rate within our sales representatives. This churn was caused primarily by failures to meet sales performance goals as well as departures precipitated, we believe, by our decision to require all employees to adhere to a full-time, in office work environment as well as a tightening labor market creating increased competition when hiring. During the year ended December 31, 2024, we hired 443 new sales representatives and ended the year with 650 sales representatives, a net decrease of 7 sales representatives from our total sales representatives at December 31, 2023. Our ability to recruit and retain all of our employees depends on a number of factors, including professional development, compensation and benefits, and employee engagement.

Page 12 of 96

A total of 942 employees transitioned to the Company on the Closing Date in connection with the acquisition of the Sprint Business. From the Closing Date through December 31, 2024,624 of these employees remained - we terminated 151 of these employees and 167 voluntarily resigned after a material reduction in their job duties. We paid approximately $28.6 million in severance costs, to qualifying employees, in accordance with the terms of the Purchase Agreement. We were fully reimbursed for these severance costs by the Seller.

Professional Development. We recognize the importance of retaining our employees, and we continually strive to improve the performance of our personnel to reduce turnover. To that end, we have invested heavily in professional development as a means for improving performance.

As part of our commitment to professional development of our sales personnel, we established a sales training and enablement department that provides both online and in-person training. Our 15 regional learning managers and management development trainers are located around the world and are available for intensive, in-person group training as well as individual training with sales representatives who may need extra assistance. For the year ended December 31, 2024, our ratio of sales representatives with less than 12 months of tenure to regional learning managers was 20 to 1.

Our training group includes two additional trainers dedicated exclusively to training sales management, one trainer dedicated exclusively to our field services team, one technical trainer, one on-line curriculum trainer, one trainer dedicated to network operations and customer service, one trainer for customer care and three project managers. Our trainers also conduct training in our offices to learn new skills and reinforce existing skills.

All sales personnel receive live, interactive training during their first month of employment, which focuses on developing both general and Cogent-specific sales skills. New sales personnel are also encouraged to, and rewarded for, completing a self-paced, online curriculum led by their manager during their first six months. Both recent and tenured sales personnel have access to online, on-demand training modules and the opportunity to obtain certification in specialized services. Our CEO addresses each new hire class in an interactive training session.

Compensation and Benefits. We are committed to rewarding, supporting, and developing our employees. To that end, we offer a comprehensive compensation program that includes market-competitive pay, stock options or restricted stock grants to all eligible employees, healthcare benefits, life insurance, a retirement savings plan, and paid time off and family leave.

Employee Engagement. To foster and reinforce a company culture where employee concerns are heard, our Chief Executive Officer conducts biweekly town hall meetings to respond to employee questions, which may be submitted anonymously. On alternate weeks, we conduct online town hall chats during which a rotating member of the executive team is available to answer questions from our employees. We believe these open and unfiltered channels of communication lead to honest feedback from our employees to our management team.

Health and Safety. The health and safety of our employees is of utmost important to us, and we take all necessary precautions to safeguard our employees. While nearly all of our employees work solely in office environments, for our field personnel, we provide safety gear as appropriate given employee job duties. We also provide training to our field personnel in a variety of workplace safety topics. With respect to our decision to require all employees to work in an in-office environment, we continue to mandate that all employees in the United States and Canada, except those with legal exemptions, be vaccinated against the against the COVID-19 virus.

Sales and Marketing

Direct Sales. We employ a direct sales and marketing approach. As of December 31, 2024, our sales force included 843 full-time employees. Our quota-bearing sales force includes 650 employees with 347 employees focused primarily on the corporate market, 288 employees focused primarily on the net-centric market and 15 employees focused primarily on the enterprise market. As of December 31, 2023, our sales force included 847 full-time employees. Our quota-bearing sales force includes 657 employees with 374 employees focused primarily on the corporate market, 271 employees focused primarily on the net-centric market and 12 employees focused primarily on the enterprise market. Our sales personnel work through direct contact with potential customers in, or intending to locate in, our on-net buildings. Through agreements with building owners and CNDC operators, we are able to initiate and maintain personal contact with our customers by staging various promotional and social events in our MTOBs and CNDCs. Sales personnel are compensated with a base salary plus quota-based commissions and incentives. We use a customer relationship management system to efficiently track sales activity levels and sales productivity.

Page 13 of 96

Indirect Sales. In 2024, we discontinued our indirect sales program, as we determined that it was not financially effective.

Marketing. Because of our historical focus on a direct sales force that utilizes direct contact, we have not spent funds on television, radio or print advertising. We use a limited amount of web-based advertising. Our marketing efforts are designed to drive awareness of our products and services, to identify qualified leads through various direct marketing campaigns and to provide our sales force with product brochures, collateral materials, in building marketing events and relevant sales tools to improve the overall effectiveness of our sales organization. In addition, we conduct building events and public relations efforts focused on cultivating industry analyst and media relationships with the goal of securing media coverage and public recognition of our Internet access, colocation and private network services.

Competition

We face competition from incumbent telephone and cable companies, and facilities-based network operators, many of whom are much larger than us, have significantly greater financial resources, sales and marketing capabilities, better-established brand names and large, existing installed customer bases in the markets in which we compete. With respect to our new optical wave and transport service, our competitors have offered these services for many years and have established customer bases and processes and practices. We also face competition from new entrants to the communications services market. Many of these companies offer products and services that are similar to our products and services.

For the portions of our network that are leased under IRUs from providers, some of which compete with us, we do not have title to the dark fiber. We rely on the owner of this leased fiber to maintain the fiber. We also depend on third-party providers, some of which compete with us, to provide intercity and intracity fiber as well as the lateral fiber connections required to add buildings to our network and to provide the local loop facilities for the provision of connections to our off-net customers.

We believe that competition is based on many factors, including price, transmission speed, ease of access and use, length of time to provision service, breadth of service availability, reliability of service, customer support, billing simplicity and brand recognition. While the Internet access speeds offered by traditional ISPs serving MTOBs using DSL or cable modems typically do not match our on-net offerings in terms of throughput or quality, these slower services are usually priced lower than our offerings and thus provide competitive pressure on pricing, particularly for more price-sensitive customers. These and other downward pricing pressures, particularly in CNDCs, have diminished, and may further diminish, the competitive advantages that we have enjoyed as the result of the pricing of our services. Increasingly, traditional ISPs are upgrading their services using optical fiber and cable technology so that they can match our transmission speed and quality.

The acquisition of the Sprint Network has provided additional competitive benefits. While the Sprint Network was built in the 1980s (the nation’s first transcontinental fiber network), we believe it is of high quality and superior to many newer networks. First, it has had only one owner, which ensures accurate and up-to-date records and mapping. Second, it has been well maintained by a tenured engineering and field team, many of whom transitioned with the acquisition and remain employed with the Company. Third, the fiber is buried deeper than newer networks with stronger sheathing, mitigating some of the damage caused by inadvertent cuts. Lastly, it is one consistent standard of fiber – SMF28 - which is ideal for the requirements of today’s traffic, particularly wave services, with the new optronics we are adding to the network.

Regulation

Our network services are subject to the regulatory authority of various agencies in the jurisdictions in which we operate. As a provider of only Internet access and private networks to businesses, regulation is generally not significant. This benefits us in that we have flexibility in offering our services and ease of entry into new markets. However, this level of regulation generally extends to our competitors, some of whom are incumbent telephone and cable companies with whom we need to interconnect and from whom we acquire circuits for our off-net services. The extent of regulation can change.

In January 2025, the U.S. Court of Appeals for the Sixth Circuit struck down the U.S. Federal Communications Commission (“FCC”) 2024 Net Neutrality Order. In the 2024 Net Neutrality Order, the FCC classified broadband as a telecommunications service. In setting aside the 2024 Net Neutrality Order, the Sixth Circuit held that broadband providers offer only an information service and therefore the FCC lacked the statutory authority to impose net-neutrality policies through Title II of the Communications Act of 1934.

The decision by the Sixth Circuit does not apply to state laws protecting net neutrality. For example, the California Internet Consumer Protection and Net Neutrality Act, previously upheld by the U.S. Court of Appeals for the Ninth Circuit in 2022, is not impacted by the January 2025 ruling.

Page 14 of 96

In all jurisdictions regulations continue to evolve. We also enter into new markets with their own regulations. The regulations with which we need to comply include obtaining the proper licenses to provide our services, data privacy, and interception of communications by law enforcement, blocking of websites, net-neutrality in California and other states in the U.S. and other regulations. We believe that we comply with all regulations in the jurisdictions in which we operate.

The laws related to Internet telecommunications are unsettled and there may be new legislation and court decisions that may affect our services and expose us to burdensome requirements and liabilities.

Our fiber network and associated facilities and equipment particularly in the United States are also subject to the regulatory authority of various agencies in which the network and facilities are located. These regulations include environmental, health and safety reporting and compliance. We have established a compliance team to manage this effort.

ITEM 1A. RISK FACTORS

Market Risks

Our growth and financial health are subject to a number of economic risks.

A downturn in the world economy, especially the economies of North America and Europe, would negatively impact our growth. Our net-centric business would be particularly impacted by a decline in the development of new applications and businesses that make use of the Internet. Our corporate business would be particularly impacted by an increase in vacancy rates in the MTOBs that we serve. Our total revenue growth is predicated on growth in the use of the Internet that makes up for the declining prices of Internet service. An economic downturn could impact the Internet business more significantly than other businesses that are less dependent on new applications and growth in the use of those applications and less susceptible to increases in office vacancy rates resulting from the retrenchment by consumers and businesses that typically occurs in an economic downturn.

Our historical reductions in our prices are expected to continue in an inflationary economy even as our costs may increase.

Many of the regions in which we operate continue to experience an increase in or elevated inflation rates. Due to the nature of our product offerings and the industry in which we operate, which is deflationary, we may be unable to raise our prices. We expect that our historical pricing patterns will continue for the foreseeable future.

These historical pricing patterns are occurring against the backdrop of a general increase in prices due to inflation. In particular, the cost of electricity has increased greatly in all countries where we purchase power. While we have negotiated contracts that cap price increases due to inflation or that have fixed the price of electricity, we have experienced and may continue to experience increases in the costs of electricity and other services that we cannot pass on to our customers or may only be able to pass on partially to our customers. If these price increases continue, this may impact our profitability.

Events beyond our control may impact our ability to provide our services to our customers or increase the costs or reduce the profitability of providing our services.

Catastrophic events, such as major natural disasters, extreme weather, fire, flooding, pandemics such as the COVID-19 pandemic or similar events as well as the continued threat of terrorist activity and other acts of war or hostility have had, and may continue to have, an adverse effect on our headquarters, other offices, our network, infrastructure or equipment or our customers and prospective customers, which could adversely affect our business. These events may also have an adverse impact on business, financial and general economic conditions around the world. We have certain locations through which a large amount of our Internet traffic passes. Examples are facilities in which we exchange traffic with other carriers, the facilities through which our transoceanic traffic passes, and certain of our network hub sites. We are particularly vulnerable to acts of terrorism because our largest customer concentration is

Page 15 of 96

located in New York, our headquarters is located in Washington, D.C., and we have significant operations in Paris, Madrid and London, cities that have historically been targets for terrorist attacks and may be vulnerable to pandemics.

If these or any other of our key facilities were destroyed or seriously damaged, a significant amount of our network traffic could be disrupted. Because of the large volume of traffic passing through these facilities our ability (and the ability of carriers with whom we exchange traffic) to quickly restore service would be challenged. There could be parts of our network or the networks of other carriers that could not be quickly restored or that would experience substantially reduced service for a significant time. If such a disruption occurs, our reputation could be negatively impacted, which may cause us to lose customers and adversely affect our ability to attract new customers, resulting in an adverse effect on our business and operating results.

Risks Relating to Our Acquisition of the Sprint Business

We may not realize the anticipated benefits of the acquisition of the Sprint Business, and the integration of the Sprint Business may disrupt our business and management.

The success of our acquisition of the Sprint Business, including the realization of anticipated benefits and cost savings, will depend, in part, on our ability to successfully combine our business and the Sprint Business. The integration may be more difficult, costly or time consuming than expected. The integration process involves numerous risks. These risks include:

Page 16 of 96

If we experience difficulties during the integration process and are unable to integrate the Sprint Business successfully or in a timely manner, we may not realize the benefits of the Transaction to the extent anticipated. These integration matters could have an adverse effect on us during the transition period and on the combined company for an undetermined period after completion of the Transaction.

Business Risks

We need to retain existing customers and continue to add new customers in order to become consistently profitable and cash flow positive.

In order to be consistently profitable and consistently cash flow positive, we need to both retain existing customers and continue to add a large number of new customers. The precise number of additional customers required is dependent on a number of factors, including the turnover of existing customers, the pricing of our product offerings and the revenue mix among our customers. We may not succeed in adding customers if our sales and marketing efforts are unsuccessful. In addition, many of our targeted customers are businesses that are already purchasing Internet access services from one or more providers, often under a contractual commitment. It has been our experience that such targeted customers are often reluctant to switch providers due to costs and effort associated with switching providers. Further, as some of our customers grow larger, they may decide to build their own Internet backbone networks or enter into direct connection agreements with telephone and cable companies that provide Internet service to consumers. A migration of a few very large Internet users to their own networks, or to closed networks that may be offered by major telephone and cable providers of last mile broadband connections to consumers, or the loss or reduced purchases from several significant customers could impair our growth, cash flow and profitability.

We have customers who depend on the U.S. government’s E-rate program for funding. There can be no assurance that the E-rate program will continue or that other governmental programs that fund governments and organizations that are or might become customers will continue. A failure of such programs to continue could result in a loss of customers and impair our growth, cash flow and profitability.

A substantial and long-term shift to remote work may impact our ability to add new customers and to retain existing customers.

Through much of 2022, 2023, and 2024, we saw corporate customers continue their remote work policies and take a cautious approach to new services and upgrades, as well as a reduced demand for connecting smaller satellite offices. We also witnessed a deteriorating real estate market in and around the buildings we service, with rising vacancy levels and falling lease initiations or renewals resulting in fewer sales opportunities for our salesforce. As a result, we experienced a slowdown in new sales to our corporate customers which negatively impacted our corporate revenue growth. If a significant number of our corporate customers or potential customers decide to retain remote work policies, we may experience increased customer turnover, fewer upgrades of existing customer configurations and fewer new tenant opportunities. These trends may negatively impact our revenue growth, cash flows and profitability.

Lower vacancy rates as a result of diminished lease terminations and increased leasing and subleasing activity will be a key factor in driving renewed growth in our corporate business.

During the COVID-19 pandemic, we saw increasing vacancy rates in many of our buildings due to higher lease terminations and lower leasing activity. Throughout the year ended December 31, 2024, we observed a gradual reduction in vacancy rates and an upward trend in office occupancy rates but elevated vacancy rates remain in a number of markets, predominantly in California, Washington D.C. and the Pacific Northwest. Concurrently, there were encouraging developments in our corporate business. Despite these positive indicators, the precise timing and trajectory of these trends remain uncertain. The lingering effects of the pandemic introduce an element of unpredictability, and we may continue to see increased corporate customer turnover, fewer upgrades of existing corporate customer configurations and fewer new tenant opportunities, which would negatively affect our corporate revenue growth. The elimination of non-core and low margin products also has a negative impact on our corporate revenue results.

Page 17 of 96

Our business and operations are growing rapidly, and we may not be able to efficiently manage our growth.

We have grown our Company rapidly through network expansion, by obtaining new customers through our sales efforts and by our acquisition of the Sprint Business. Our expansion places significant strains on our management, operational and financial infrastructure. Our ability to manage our growth will be particularly dependent upon our ability to:

If we fail to implement these measures successfully, our ability to manage our growth will be impaired.

We may be unable to retain existing enterprise customers, maintain the level of services provided to enterprise customers or attract new enterprise customers.

In connection with the acquisition of the Sprint Business, we acquired an enterprise customer base, a type of customer that we have not traditionally served. We have established an enterprise sales team within our sales force to focus on retaining these customers and attracting new enterprise customers. Enterprise customers differ from our existing corporate and net-centric customers in that they have larger, more geographically diverse operations that require a greater percentage of off-net services from us. In addition, enterprise customers are more likely to require customized solutions and processes and to look for a single provider to meet their connectivity needs. A number of our acquired enterprise customers purchased non-core services that we are in the process of eliminating, and this may cause such customers to look to other providers who offer a broader set of services. We may encounter difficulties retaining such customers, in converting such customers from their legacy services to newer technologies or in attracting new enterprise customers. Our inability to retain or attract such customers or to convert them to our services, could impair our growth, cash flow and profitability. The elimination of non-core and low margin products also has a negative impact on our enterprise revenue results.

Demand from certain employees to work remotely may reduce the attractiveness of our business as an employer versus some competitors who are allowing employees to work remotely.

In the fall of 2021, we began to implement an in-office work policy designed to return the vast majority of our employees to an in-office work environment. Except for a brief return to remote work at the beginning of 2022 for a portion of our workforce, we have, with the exception of a limited number of employees who become eligible for hybrid work on a quarterly basis, maintained our requirement that all employees work in our offices wherever possible. A small minority of our workforce declined to return to full-time in-office employment and left our employment. We are experiencing modest competitive challenges versus some competitors who are offering some employees a hybrid work option. Increasing demands to work in a hybrid work style may reduce our ability to attract and retain employees, in particular attracting and retaining salespeople.

We may not successfully make or integrate acquisitions or enter into strategic alliances.

As part of our growth strategy, we may pursue selected acquisitions and strategic alliances. To date, we have completed 14 significant acquisitions, including our recent acquisition of the Sprint Business. However, we are very selective with respect to such acquisitions and alliances and, prior to the acquisition of the Sprint Business, we had not undertaken either for more than 17 years. We compete with other companies for acquisition opportunities and we cannot assure you that we will be able to execute future acquisitions or strategic alliances on commercially reasonable terms, or at all. Even if we enter into these transactions, we may experience:

Page 18 of 96

In the past, our acquisitions have often included assets, service offerings and financial obligations that are not compatible with our core business strategy. We have expended management attention and other resources to the divestiture of assets, modification of products and systems as well as restructuring financial obligations of acquired operations. In most acquisitions, we have been successful in renegotiating the agreements that we have acquired. If we are unable to satisfactorily renegotiate such agreements in the future or with respect to future acquisitions, we may be exposed to large claims for payment for services and facilities we do not need.

Consummating these transactions could also result in the incurrence of additional debt and related interest expense, as well as unforeseen contingent liabilities, all of which could have a material adverse effect on our business, financial condition and results of operations. Because we have typically purchased financially distressed companies or their assets, and may continue to do so in the future, we have largely not had, and may not in the future have, the opportunity to perform extensive due diligence or obtain contractual protections and indemnifications that are customarily provided in acquisitions. As a result, we may face unexpected contingent liabilities arising from these acquisitions. We may also issue additional equity in connection with these transactions, which would dilute our existing shareholders.

Following an acquisition, we have experienced a decline in revenue attributable to acquired customers as these customers’ contracts have expired and they have entered into our standard customer contracts at generally lower rates or have chosen not to renew service with us. We anticipate that we would experience similar revenue declines with respect to customers we may acquire in the future.

Our data center expansions could involve significant risks to our business.

To sustain our growth in various existing and emerging markets, we may need to expand an existing data center, lease a new facility, or acquire suitable land, with or without existing structures. Following the acquisition of the Sprint Business, we embarked on the conversion of Sprint facilities into data centers suitable for either wholesale lease or sale – of which 23 are wholesale facilities and 55 are edge data center facilities. Undertaking such projects exposes us to numerous risks that could adversely impact our financial condition and operational results. The prevailing global supply chain challenges and inflation have further heightened these risks, introducing additional uncertainties into our business.

The selection of suitable sites is a critical factor in our expansion plans. It is possible that there may be a lack of available properties in our target markets with the required combination of high-power capacity and fiber connectivity, or the options may be limited. Anticipating ongoing challenges in power availability and grid constraints in various markets, coupled with shortages of associated equipment due to heightened demand and the finite nature of these resources, we may encounter difficulties in site selection, leading to construction delays, increased costs, lower interconnection revenue, reduced margins, and potential negative implications for customer retention over time.

Currently, we are dealing with escalating construction costs attributed to the rising expenses of labor and raw materials, logistical challenges in the supply chain, and heightened demand in our sector. Despite having invested in building up a reserve of materials to address supply chain issues and inflation, there exists the possibility that it may not be sufficient. Persistent delays, difficulties in finding replacement products, and continued high inflation could potentially affect our business and growth, significantly affecting our overall business standing. Any unforeseen disruptions to our supply chain or inflationary pressures might substantially impact the costs associated with our planned expansion projects, potentially hindering our ability to fulfill commitments to customers who have contracted for space in new data centers under construction.

Page 19 of 96

Construction projects are dependent on receiving permits from public agencies and utility companies. Any delay in receiving permits could delay our construction projects and affect our growth. While we do not currently anticipate any material long-term negative impact to our business because of construction delays, these types of delays and stoppages related to receiving permits from public agencies and utility companies could worsen and have an adverse effect on our bookings, revenue or growth.

Furthermore, construction related projects require us to carefully select and rely on the experience of one or more designers, general contractors, and associated subcontractors during the design and construction process. Should a designer, general contractor, significant subcontractor or key supplier experience financial problems or other problems during the design or construction process, we could experience significant delays, increased costs to complete the project and/or other negative impacts to our expected returns.

We may be unable to lease or sell data centers on attractive financial terms, in sufficient volume or at all. If we are unable to do so, we may not recover the costs incurred in converting these facilities to data centers and that could adversely impact our financial condition and operational results.

Our commitments and disclosures regarding environmental, social, and governance (“ESG”) matters expose us to potential reputational and legal risks.

The perception of our ESG profile as less attractive to customers or employees may impact our brand and reputation. Our level of commitment to ESG initiatives could influence our ability to attract or retain customers and employees. The timing, scope, or nature of these initiatives, goals, or commitments, as well as any revisions, may lead to criticism. Scrutiny regarding the accuracy, adequacy, or completeness of ESG disclosures may arise. Any perceived failure to achieve our ESG-related initiatives, goals, commitments, or mandates could adversely affect our reputation and materially harm our business. Conversely, if public or investor sentiment turns against ESG-related initiatives, our commitment to ESG initiatives at any level could lead to government scrutiny or private litigation or otherwise adversely affect our reputation and materially harm our business.

The growing emphasis on ESG matters has prompted the adoption of legal and regulatory requirements to address climate change effects and necessitate additional disclosures. If new laws or regulations surpass current requirements, we may face heightened compliance burdens and increased costs. Our selection of voluntary disclosure frameworks and standards, as well as their interpretation or application, may change and might not align with investor or stakeholder expectations. Achieving our ESG commitments is contingent on numerous external factors beyond our control, including evolving and potentially inconsistent regulatory requirements, supplier availability meeting our standards, and the recruitment, development, and retention of diverse talent.

Competitive Risks

Our connections to the Internet require us to establish and maintain relationships with other providers, which we may not be able to maintain.

The Internet is composed of various network providers who operate their own networks that interconnect at public and private interconnection points. Our network is one such network. In order to obtain Internet connectivity for our network, we must establish and maintain relationships with other ISPs and certain of our larger customers. These providers may be customers (who connect their network to ours by buying Internet access from us) or other large ISPs to whom we connect on a settlement-free peering basis as described below. Both customers and settlement-free peers may be competitors of ours.

By entering into what are known as settlement-free peering arrangements, providers agree to exchange traffic between their respective networks without charging each other. Our ability to avoid the higher costs of acquiring paid dedicated network capacity (transit or paid peering) and to maintain high network performance is dependent upon our ability to establish and maintain settlement-free peering relationships and to increase the capacity or add additional locations of the interconnections provided by these relationships. The terms and conditions of our settlement-free peering relationships may also be subject to adverse changes, which we may not be able to control. If we are not able to maintain or increase our settlement-free peering relationships in all of our markets on favorable terms or to upgrade the capacity of our existing settlement-free peering relationships, customers may not upgrade their connections with us or we may not be able to provide our customers with high performance, affordable or reliable services, which could cause us to lose existing and potential customers, damage our reputation and have a material adverse effect on our business. Additionally, certain of our current customers may seek to become settlement-free peers with us.

We cannot assure you that we will be able to continue to establish and maintain relationships with other ISPs, favorably resolve disputes with such providers, or increase the capacity of our settlement-free peering interconnections with such providers.

The sector in which we operate is highly competitive, and we may not be able to compete effectively.

We face significant competition from incumbent carriers, Internet service providers and facilities-based network operators. Relative to us, many of these providers have significantly greater financial resources, more well-established brand names, larger customer bases, and more diverse strategic plans and service offerings. A number of these providers also have large bases of consumers, which makes their networks particularly attractive to content providers as they can provide a direct connection to their customers.

Intense competition from these traditional and new communications companies has led to declining prices and margins for many communications services, and we expect this trend to continue as competition intensifies in the future. Decreasing prices for high-speed Internet services have somewhat diminished the competitive advantage that we have enjoyed as a result of our service pricing.

Our business is premised on the idea that customers want simple Internet access and private networks rather than a combination of such services with other services such as voice services and complex managed services. Our competitors offer such services. Should the market come to favor such services our ability to acquire and keep customers would be impaired. Our competitors may also upgrade their existing services or introduce new technologies or services, such as satellite-based Internet or 5G services that could make our services less attractive to potential customers.

Moreover, the continuous evolution of technology may empower our competitors to upgrade their existing services or introduce new, more advanced offerings that could potentially diminish our sales of VPN and colocation services. As a consequence, we may face challenges in acquiring and retaining customers.

Our business could suffer because telephone companies and cable companies may provide better delivery of certain Internet content, including content originating on their own networks, than content on the public Internet.

Broadband connections provided by cable TV, telephone, and fixed and mobile wireless companies have become the predominant means by which consumers connect to the Internet. The providers of these broadband connections may treat Internet content or other broadband content delivered from different sources differently. The possibility of this has been characterized as an issue of “net neutrality.” As many of our customers operate websites and services that deliver content to consumers, our ability to sell our services would be negatively impacted if Internet content delivered by us was less easily received by consumers than Internet content delivered by others. The FCC had promulgated rules that would have banned practices such as blocking and throttling of Internet traffic, but those rules were rescinded by the FCC in December 2017. A subsequent attempt to reintroduce these rules in 2024 was overturned by the U.S. Court of Appeals for the Sixth Circuit in 2025. Furthermore, the Sixth Circuit decision appears to foreclose any future possibility of the FCC reclassifying broadband as a telecommunications service, a designation that allows the FCC to regulate ISPs under the common-carrier provisions in Title II of the Communications Act. While certain US states, including California, have either issued or are considering their own net neutrality rules, it is unclear whether these state regulations should have the same national impact as the former FCC order. Also, the European Union and other countries in which we operate have issued similar net neutrality rules. We also do not know the extent to which the providers of broadband Internet access to consumers may favor certain content or providers in ways that may disadvantage us.

Operational Risks

Our network may be the target of potential cyber-attacks and other security breaches that could have significant negative consequences.

We rely on our own and third-party computer systems, hardware, software, technology infrastructure and online sites and networks for both internal and external operations that are critical to our business (collectively, “IT Systems”). We own and manage some of these IT Systems but also rely on third parties for a range of IT Systems and related products and services, including but not limited to cloud computing services.

Our business depends on our ability to limit and mitigate interruptions to or degradation of the security of our network. We face numerous and evolving cybersecurity risks that threaten the confidentiality, integrity and availability of our IT Systems, as well as trade secrets, intellectual property, personal information or other Company confidential information (collectively “Confidential Information”). We are considered a critical infrastructure provider and therefore may be more likely to be the target of cyber-attacks. Our IT Systems are subject and vulnerable to unauthorized access, social engineering/phishing, malware (including ransomware), malfeasance by insiders, human or technological error, and as a result of bugs, misconfigurations or exploited vulnerabilities in software or hardware, computer viruses, cyber-attacks, distributed denial of service (“DDOS”), and other cybersecurity risks.

Page 21 of 96

We and our employees are the target of phishing attempts and compromised links, and our IT Systems are the target of attempts at unauthorized access, a small number of which have been successful in accessing non-critical areas of our IT Systems. Our customer-facing network firewall regularly suppresses cyber-attacks and our network routinely manages DDOS attacks. Although none of the incidents, individually or in the aggregate, have materially impacted our operations or business, we cannot guarantee material incidents will not occur in the future. An attack on or security breach of our network could result in theft of Confidential Information, the interruption, degradation, or cessation of services, an inability to meet our service level commitments or our financial reporting obligations, and could potentially compromise customer data stored on or transmitted over our network.

Cyber-attacks are expected to accelerate on a global basis in frequency and magnitude as threat actors are becoming increasingly sophisticated in using techniques and tools – including artificial intelligence – that circumvent security controls, evade detection and remove forensic evidence. As a result, we may be unable to detect, investigate, remediate or recover from future attacks or incidents, or avoid a material adverse impact to our IT Systems, Confidential Information or business. Moreover, as cyber warfare becomes a tool in asymmetric conflicts between the United States and other nations, we, as a US provider, may be targeted with increasing frequency. We cannot guarantee that our security measures will not be circumvented, thereby resulting in security events, network failures or interruptions that could impact our network security or availability and have a material adverse effect on our business, our ability to meet our financial reporting obligations, brand and reputation, financial condition and operational results.

We may be required to expend significant resources to protect against such threats, and may experience a reduction in revenues, litigation (including class action lawsuits), and a diminution in goodwill, caused by a compromise of our cybersecurity. Although our customer contracts limit our liability, affected customers and third parties may seek to recover damages from us under various legal theories. We cannot guarantee that any costs and liabilities incurred in relation to an attack or incident will be covered by our existing insurance policies or that applicable insurance will be available to us in the future on economically reasonable terms or at all. In response to past attacks, we have implemented additional controls and taken and planned for other preventative actions to further strengthen our systems against future attacks. However, we cannot assure you that such measures will provide absolute security, that we will be able to react in a timely manner, or that our remediation efforts following any past or future attacks will be successful. There can also be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our IT Systems and Confidential Information. Any adverse impact to the availability, integrity or confidentiality of our IT Systems or Confidential Information can result in legal claims or proceedings (such as class actions), regulatory investigations and enforcement actions, fines and penalties, negative reputational impacts that cause us to lose existing or future customers, and/or significant incident response, system restoration or remediation and future compliance costs. Any or all of the foregoing could materially adversely affect our business, operating results, and financial condition.

If the information systems that we depend on to support our customers, network operations, sales, billing and financial reporting do not perform as expected, our operations and our financial results may be adversely affected.

We rely on complex information systems to operate our network and support our other business functions. Our ability to track sales leads, close sales opportunities, provision services, bill our customers for our services and prepare our financial statements depends upon the effective integration of our various information systems. In 2020, we developed and deployed our own customer relationship management software for our sales force. We may have difficulty maintaining this software and adding features that our sales representatives require. If our information systems, individually or collectively, fail or do not perform as expected, our ability to make sales, to process and provision orders, to make timely payments to vendors, to ensure that we collect amounts owed to us and prepare and file our financial statements would be adversely affected. Such failures or delays could result in increased capital expenditures, customer and vendor dissatisfaction, loss of business or the inability to add new customers or additional services, and the inability to prepare accurate and timely financial statements all of which would adversely affect our business and results of operations.

Our insurance coverage may be insufficient to fully protect against potential risks.

We maintain various insurance policies, including liability, property, and others, to safeguard our company against insurable risks. Our choice of insurance types, coverage limits, and deductibles is determined by our unique risk profile, the balance between insurance costs and perceived benefits, and prevailing industry norms. There is a possibility that any of the insurance limits we secure, whether for flood or other risks, might be insufficient. Such inadequacy could significantly and negatively affect our business, financial health, and operational outcomes.

Page 22 of 96

Cogent has not signed a Legacy Registration Services Agreement with the American Registry for Internet Numbers (“ARIN”) or any other regional Internet registry (“RIR”) with respect to a substantial portion of our IPv4 addresses.

Many of the IPv4 addresses we own were originally allocated prior to the creation of ARIN and the other RIRs. As such, ARIN requires us (and any other legacy resource holder) to enter into a Legacy Registration Services Agreement to obtain access to the full range of ARIN services, including, its Resource Public Key Infrastructure (“RPKI”) and Internet Routing Registry (“IRR”). We have elected not to enter into a Legacy Registration Services Agreement with ARIN. As a result, while the IPv4 addresses appear in the ARIN database as under our ownership and control and we have access to a limited set of ARIN services, the Company cannot implement RPKI on these IPv4 addresses.

RPKI is a framework that enables network operators to secure routing infrastructure by associating IPv4 address ranges with autonomous system numbers. By doing so, RPKI greatly reduces the possibility of route hijacking and leaks when using Border Gateway Protocol (“BGP”) on the Internet. Our inability to obtain access to RPKI services and authentication may cause some customers to prefer to lease IPv4 addresses from companies that offer RPKI, leading to a loss of revenue for us. In addition, without RPKI, we are unable to monitor its network proactively with respect to these IPv4 addresses and these IPv4 addresses are at a greater risk for route hijacking. Moreover, since these IPv4 addresses do not have RPKI certification, the process for reclaiming a hijacked route is prolonged and requires the assistance of other network operators. This increased potential for route hijacking and longer recovery time may also result in some customers opting to lease IPv4 addresses from our competitors.

Network Augmentation and Maintenance Risks

Our network is comprised of a number of separate components, and we may be unable to obtain or maintain the agreements necessary to augment or maintain our network.

Our network is primarily composed of (i) leased capacity on transoceanic optical fiber; (ii) terrestrial inter-city dark optical fiber; (iii) intra-city dark optical fiber; (iv) right-of-way agreements; and (v) the buildings that we serve and the associated optical fiber connecting those buildings. We both own and lease portions of our optical fiber and obtain access to the buildings on our network, both CNDCs and MTOBs, from a number of vendors. A number of our leases, both for fiber and building access, are up for renewal in any given year. A deterioration in our existing relationship with these operators could impact our network, harm our sales and marketing efforts and could substantially reduce our potential customer base. In addition, portions of our long-haul optical fiber and metro optical fiber are nearing the end of their original projected useful life. While we believe that this fiber will remain usable beyond the projected end date, we face the risk that portions of our network may need to be replaced in the future.

We expect to enter additional agreements with carriers and operators to obtain additional facilities, whether optical fiber, leased transoceanic capacity or buildings, for our network in order to add capacity to our network and to expand our addressable market. However, we cannot assure you that we will be able to enter into such agreements in the future, be able to do so on economically attractive terms or find an adequate substitute if we are unable to reach an agreement. Failure to acquire new facilities to augment our network could keep us from adding new markets, capacity or buildings to our network and negatively impact our growth opportunities.

Our off-net business could suffer delays and problems due to the actions of “last mile” providers on whom we are partially dependent.

Our off-net customers are connected to our network by means of fiber optic capacity that is provided as services by local telephone and cable companies and others. We may experience problems with the installation, maintenance and pricing of these lines which could adversely affect our results of operations and our plans to add additional off-net customers to our network using such services. We have historically experienced installation and maintenance delays when the network provider is devoting resources to other services, such as traditional telephony, cable TV services and private network services. We have also experienced pricing problems when a lack of alternatives allows a provider to charge high prices for capacity in a particular area or to a particular building. We attempt to reduce this problem by using many different providers so that we have alternatives for linking an off-net customer to our network. Competition among the providers tends to improve installation intervals, maintenance and pricing. Additionally, these providers are often competing with us for the same customers and have marketed their own service to our off-net customers when our initial contract with our customer nears the end of its term.

Page 23 of 96

Our business could suffer from an interruption of service from our fiber providers.

The optical fiber cable owners from whom we have obtained our inter-city and intra-city dark fiber maintain that dark fiber. We are contractually obligated under the agreements with these carriers to pay maintenance fees, and if we are unable to continue to pay such fees, we would be in default under these agreements. If these carriers fail to maintain the fiber or disrupt our fiber connections due to our default or for other reasons, such as business disputes with us, bankruptcy, and governmental takings, our ability to provide service in the affected markets or parts of markets would be impaired unless we have or can obtain alternative fiber routes. Some of the companies that maintain our inter-city dark fiber and some of the companies that maintain our intra-city dark fiber are also competitors of ours in portions of our business. Consequently, they may have incentives to act in ways unfavorable to us. We may incur significant delays and costs in restoring service to our customers in connection with future service interruptions, and as a result we may lose customers.

With the Sprint Business acquisition, our reliance on agreements with landowners has increased.

Since the acquisition of the Sprint Business, our reliance on rights-of-way, license agreements, franchises, and authorizations from governmental bodies, railway companies, utilities, carriers, and other third parties has increased. These permissions allow us to place a portion of our network equipment on, over, or under their respective properties. However, a significant challenge is that some of these authorizations have set expiration dates within the next five to ten years, and renewing or extending them is essential. The potential adverse impact on our operations looms if any of these authorizations are canceled, terminated, or allowed to lapse, or if landowners request price increases. The uncertainty lies in our ability to successfully extend these arrangements upon expiration or establish new agreements necessary for executing our network expansion initiatives. We cannot guarantee our success in these endeavors, raising concerns about the continuity of our operations and our ability to capitalize on network expansion opportunities.

Effects of climate change may impose risk of damage to our infrastructure and our ability to provide services.

Long-term climate change may give rise to extreme weather events, posing a direct threat to network facilities and impeding our ability to construct and maintain segments of our network. Such events could also disrupt suppliers, impacting their ability to deliver products and services essential for ensuring reliable network coverage. Any resulting disruptions have the potential to postpone our network deployment plans, interrupt customer services, escalate our operational costs, and adversely affect our overall operating results. The physical consequences of climate change, including heightened frequency and severity of storms, floods, fires, freezing conditions, and sea-level rise, could negatively impact our operations, infrastructure, and financial performance. Operational setbacks arising from these physical effects, such as damage to our network infrastructure, might lead to increased costs and revenue losses. To address these challenges, we may need to invest significantly in enhancing the climate resilience of our infrastructure and undertaking preparations, responses, and mitigation measures for the physical impacts of climate change. Despite these considerations, accurately predicting the materiality of potential losses or costs associated with these effects remains challenging.

We are responsible for maintenance and repair of our owned fiber network.

With the acquisition of the Sprint Business, our operations now include the ownership of a substantial fiber network. With this ownership, we assume the critical responsibility for the maintenance and repair of the entire fiber infrastructure. This introduces inherent risks that could impact our operational continuity. As we did not own a fiber network historically, the new responsibility necessitates an adjustment in our operational approach and poses challenges affecting the efficiency of maintenance activities. If we are unable to maintain our fiber or adequately and efficiently manage disruptions to our fiber network, our ability to provide services in the affected markets or parts of markets would be impaired unless we have or can obtain alternative fiber routes. In addition, we may incur unexpected and significant costs, delays or other difficulties in maintaining or repairing our fiber infrastructure, resulting in increased disruption in services to our customers. We may, as a result, lose revenue or customers.

Substantially all of our network infrastructure equipment is manufactured or provided by a limited number of network infrastructure vendors.

We purchase our network infrastructure equipment from a small circle of vendors. Historically, we purchased from Cisco Systems, Inc. (“Cisco”) all of the routers and transmission equipment used in our network. We have expanded our suppliers of routers, added Arista Networks, Inc. (‘Arista”) as a provider for certain types of routers but Cisco remains our primary vendor for routers. With the acquisition of the Sprint Business in 2023, we entered into an agreement to purchase routers and transmission from Ciena Corporation (“Ciena”). We use Ciena equipment for optical wave transport services.

Page 24 of 96

If Cisco, Ciena or Arista fail to provide equipment on a timely basis or fails to meet our performance expectations, including in the event that either vendor fails to enhance, maintain, upgrade or improve the hardware or software products we purchase from them when and how we need them, we may be delayed or unable to provide services as and when requested by our customers. We also may be unable to upgrade our network and face greater difficulty maintaining and expanding our network.

Transitioning from Cisco, Ciena, or Arista to another vendor for the types of equipment each provides would be disruptive because of the time and expense required to learn to install, maintain and operate the new vendor’s equipment and to operate a multi-vendor network. Any such disruption could increase our costs, decrease our operating efficiencies and have an adverse effect on our business, results of operations and financial condition.

Cisco, Ciena or Arista may also be subject to litigation with respect to the technology on which we depend, including litigation involving claims of patent infringement. Such claims have been growing rapidly in the communications industry. Regardless of the merit of these claims, they can result in the diversion of technical and management personnel or require us to obtain non-infringing technology or enter into license agreements for the technology on which we depend. There can be no assurance that such non-infringing technology or licenses will be available on acceptable terms and conditions, if at all.

International Operations Risks

Our international operations expose us to numerous risks.

We have expanded our network into 56 countries worldwide on every continent other than Antarctica. We continue to explore expansion opportunities. We have experienced difficulties, ranging from lack of dark fiber, to regulatory issues, to slower revenue growth rates from our operations in these markets. If we are not successful in developing our market presence in these regions, our operating results and revenue growth could be adversely impacted.

Our international operations involve a number of risks, including:

As we continue to expand into other countries, our success will depend, in part, on our ability to anticipate and effectively manage these and other risks. Our failure to manage these risks and grow our operations outside the United States may have a material adverse effect on our business and results of operations.

Litigation Risks

As an Internet service provider, we may incur liabilities for the content disseminated through our network or for network failures, delays or errors in transmissions.

The law relating to the liabilities of ISPs for information carried on or disseminated through their networks is unsettled. As the law in this area develops and as we expand our international operations, the potential imposition of liabilities upon us for the behavior of our customers or the information carried on and disseminated through our network could require us to implement measures to

Page 25 of 96

reduce our exposure to such liabilities, which may require the expenditure of substantial resources or the discontinuation of certain products or service offerings. Any costs that are incurred as a result of such measures or the imposition of liabilities could have a material adverse effect on our business.

Regulatory Risks

Compliance with existing and proposed privacy regulations is costly, and any failure by us or our vendors to comply may result in significant liability, negative publicity, and/or an erosion of trust that may materially impact our business.

Many countries in which we operate, including the United States, are considering adopting, or have already adopted, privacy regulations, laws, rules or industry standards that that apply generally to the handling of information about individuals. The primary impact of these rules is on businesses that collect personal information about consumer users of their services. While we do not provide services to individual consumers, we receive, store, handle, transmit, use and otherwise process business information and information related to our employees, representatives of our business customers and service providers. This collection of business information and the personal information of our employees subjects us to a number of privacy regulations, including the General Data Protection Regulation (“GDPR”) in the European Union. These regulations, among other things, require us to make certain disclosures about our privacy policies, limit our ability to process, retain and transfer such information and provide employees with certain rights in relation to the information we collect about them. We also transmit data across the Internet, which data may include personal information collected by our customers. As the applicability of privacy regulations to the types of services we provide remains unsettled, we may be required to adopt additional measures in the future.

Privacy regulations, such as the General Data Protection Regulation in the European Union and the California Consumer Privacy Act in California vary in scope and in the obligations they impose on us. As new laws are implemented or existing structures are declared insufficient, we may find it difficult to comply with such regulations or find it costly to do so. Moreover, for our customers who collect personal information, increased regulation of the collection, processing and use of personal information may impact their business and their use of services in unknown ways. Any failure or perceived failure by us to comply with data privacy laws, rules, regulations, industry standards and other requirements could result in proceedings or actions against us by individuals, consumer rights groups, government agencies, or others. If any of these events were to occur, our business, results of operations, financial condition, and brand and reputation could be materially adversely affected.

Changes in laws, rules, and enforcement could adversely affect us.

We are not subject to substantial regulation by the FCC or the state public utilities commissions in the United States. Internet service is also subject to minimal regulation in Western Europe and in Canada. Elsewhere the regulation is greater, though not as extensive as the regulation for providers of voice services. However, governmental authorities may decide to impose additional regulation and taxes upon providers of Internet access and private network services. In addition, the acquisition of the Sprint Business has made us subject to additional or duplicate regulatory obligations, particularly in the countries where the Sprint Business has subsidiaries and related to the Sprint Business. All of these matters could inhibit our ability to remain a low-cost carrier and could have a material adverse effect on our business, financial condition and our results of operations.

As with the privacy laws described earlier, much of the law related to the liability of Internet service providers for content on the network and the behavior of our customers and their end users remains unsettled. Some jurisdictions have laws, regulations, or court decisions that impose obligations upon ISPs to restrict access to certain content. Other legal issues, such as the sharing of copyrighted information, data protection, trans-border data flow, unsolicited commercial email (“spam”), universal service, and liability for software viruses could become subjects of additional legislation and legal development and changes in enforcement policies. We cannot predict the impact of these changes on us. They could have a material adverse effect on our business, financial condition and our results of operations.

Changes in laws, rules and enforcement may also adversely affect our customers. For example, a possible repeal or curtailing of Section 230 of the Communications Decency Act in the United States could have an adverse impact on our customers and, consequently, on us. While our top 25 customers represented approximately 17.6% of our revenue for the year ended December 31, 2024, several large net-centric customers are or may be the subject of increased regulatory scrutiny, which may impact their businesses and, consequently, their use of our services in unknown ways.

Page 26 of 96

We may be required to censor content on the Internet, which we may find difficult to do and which may impact our ability to provide our services in some countries as well as impact the growth of Internet usage, upon which we depend.

Some governments attempt to limit access to certain content on the Internet. It is impossible for us to filter all content that flows across the Internet connections we provide. For example, some content is encrypted when a secure website is accessed. It is difficult to limit access to websites by blocking a fixed set of Internet addresses when the website operators engage in practices that make it difficult to block them. Should any government require us to perform these types of blocking procedures we could experience difficulties ranging from incurring additional expenses to ceasing to provide service in that country. We could also be subject to penalties if we fail to implement the censorship.

The imposition of tariffs may increase our costs of purchasing equipment or shipping equipment to our international subsidiaries.

On February 3, 2025, President Trump announced new tariffs of 25% for most imports from Canada and Mexico and 10% for imports from China. The tariffs on Canada and Mexico were delayed for 30 days. At least one of our primary equipment vendors manufactures and ships equipment that we purchase from China. If these tariffs are applied to our equipment purchases, it would increase our costs of equipment which could have an adverse effect on our financial condition and results of operations.

Further, if the United States imposes tariffs on other countries in which we operate, those countries may respond by imposing tariffs on imports from the United States. Any such tariffs may be applied to our equipment shipments from our US operating company to our international subsidiaries, increasing our costs and impacting our financial condition and results of operations.

Tax Risks

Governments may assert that we are liable for taxes which we have not collected from our customers or paid to our vendors, and we may have to begin collecting a multitude of taxes if Internet services become subject to taxation similar to the taxation of telephone service.

In the United States, Internet services are generally not subject to taxes. Consequently, in the United States we collect few taxes from our customers even though most telecommunications services are subject to numerous taxes. Various local jurisdictions have asserted or may assert that some of our operations or services should be subject to local taxes. If such jurisdictions assess taxes on prior years we may be subject to a liability for unpaid taxes that we may be unable to collect from our customers or former customers. If the taxation of Internet service is expanded, we will need to collect those taxes from our customers. The process of implementing a system to properly bill and collect such taxes may require significant resources. In addition, the FCC is considering changes to its Universal Services Fund that could result in its application to Internet services. This too would require that we expend resources to collect this tax. Finally, the cumulative effect of these taxes levied on Internet services could discourage potential customers from using Internet services to replace traditional telecommunication services and negatively impact our ability to grow our business.

Our private network services, such as our VPN services, are subject to taxes and fees in various jurisdictions including the Universal Service Contribution tax in the US. We believe we collect all required taxes; however, a jurisdiction may assert that we have failed to collect certain taxes. The expense of paying any unpaid taxes could be substantial and we might not be able to collect such back taxes from our customers.

We are subject to value-added taxes and other taxes in many jurisdictions outside of the United States. We are also subject to audit of our tax compliance in numerous jurisdictions. These may result in the assessment of amounts due that are material and therefore would have an adverse effect on us.

The utilization of certain of our net operating loss carryforwards is limited and depending upon the amount of our taxable income we may be subject to paying income taxes earlier than planned.

Section 382 of the Internal Revenue Code in the United States limits the utilization of net operating losses when ownership changes, as defined by that section, occur. We have performed an analysis of our Section 382 ownership changes and have determined that the utilization of certain of our net operating loss carryforwards in the United States is limited. Further, recent changes to the tax law in the United States and changes to tax laws in other jurisdictions in which we operate may impact our utilization of our net operating losses.

Page 27 of 96

Risk Factors Related to Our Indebtedness

Our substantial level of indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations under our notes and our other indebtedness.

Our total indebtedness, at par, at December 31, 2024 at par value, was $2.0 billion and includes $500.0 million of our 2026 Notes, $450.0 million of our 2027 Notes, $300.0 million of our 2027 Mirror Notes and $206.0 million of our IPv4 Notes. The 2026 Notes are due in March 2026 and require interest payments of $17.5 million per year, the 2027 Notes are due in June 2027 and require interest payments of $31.5 million per year, and the 2027 Mirror Notes are due in June 2027 and require interest payments of $21.0 million per year, each paid semi-annually. The IPv4 Notes are effectively due in May 2029 and require monthly interest payments of $16.3 million per year (which amount increases if the IPv4 Notes are not repaid prior to May 2029). All of our noteholders have the right to be paid the principal and any applicable premium upon an event of default and upon certain designated events, such as certain changes of control. Our total indebtedness at December 31, 2024 includes $538.4 million of finance lease obligations for dark fiber primarily under 15 to 42-year IRUs. Our total indebtedness at December 31, 2024 excludes $359.2 million of operating lease liabilities, which were required to be recorded as right-to-use assets and operating lease liabilities. The amount of our IRU finance lease obligations may be impacted due to our expansion activities, the timing of payments and fluctuations in foreign currency rates.

This substantial amount of debt may have important consequences. For instance, it could:

Our ability to satisfy our obligations including our debt depends on our future operating performance and on economic, financial, competitive and other factors, many of which are beyond our control. Our business may not generate sufficient cash flow, and future financings may not be available to provide sufficient net proceeds, to meet these obligations or to successfully execute our business strategy.

We have assumed the risk associated with variable interest rates under our interest rate swap agreement.

We are party to an interest rate swap agreement (the “Swap Agreement”) that has the economic effect of modifying the fixed interest rate obligation associated with our 2026 Notes to a variable interest rate obligation based on the Secured Overnight Financing Rate (“SOFR”) so that the interest payable on the 2026 Notes effectively became variable based on overnight SOFR. The critical terms of the Swap Agreement match the terms of the 2026 Notes, including the notional amount and the optional redemption date on February 1, 2026. Under the Swap Agreement, we pay the counterparty a semi-annual payment based upon overnight SOFR plus a contractual interest rate spread, and the counterparty pays us a semi-annual fixed 3.50% interest payment. The settlement payment is made each November and May until the Swap Agreement expires in February 2026. By entering into the Swap Agreement, we have assumed the risk associated with variable interest rates. Changes in interest rates affect the valuation of the Swap Agreement that we recognize in our consolidated statements of comprehensive income.

Despite our leverage, we may still be able to incur more debt. This could further exacerbate the risks that we and our subsidiaries face.

We and our subsidiaries may incur additional indebtedness, including additional secured indebtedness, in the future. The terms of our debt indentures restrict, but do not completely prohibit, us from doing so. In addition, the indentures allow us to issue additional notes and other indebtedness secured by the collateral under certain circumstances. Moreover, we are not prevented from incurring other liabilities that do not constitute indebtedness as defined in the indentures, including additional operating leases obligations and finance lease obligations in the form of IRUs. These liabilities may represent claims that are effectively prior to the claims of our note holders. If new debt or other liabilities are added to our debt levels, the related risks that we and our subsidiaries now face could intensify.

Page 28 of 96

The agreements governing our various debt obligations impose restrictions on our business and could adversely affect our ability to undertake certain corporate actions.

The agreements governing our various debt obligations include covenants imposing significant restrictions on our business. These restrictions may affect our ability to operate our business and may limit our ability to take advantage of potential business opportunities as they arise. These covenants place restrictions on our ability to, among other things:

In addition, our IPv4 address securitization facility requires us to maintain a specified debt service coverage ratio. Failure to maintain the debt service coverage ratio at a specified triggered level could adversely affect our business, including full or partial amortization or an event of default, as applicable. Our ability to comply with these agreements may be affected by events beyond our control, including prevailing economic, financial and industry conditions. These covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, merger and acquisition or other corporate opportunities. The breach of any of these covenants or restrictions could result in a default under the agreements governing our debt obligations.

To service our indebtedness, we will require a significant amount of cash. However, our ability to generate cash depends on many factors, many of which are beyond our control.

Our ability to make payments on and to refinance our indebtedness and to fund planned capital expenditures will depend on our ability to generate cash in the future, which, in turn, is subject to general economic, financial, competitive, regulatory and other factors, many of which are beyond our control.

Our business may not generate sufficient cash flow from operations, and we may not have available to us future borrowings in an amount sufficient to enable us to pay our indebtedness or to fund our other liquidity needs. In these circumstances, we may need to refinance all or a portion of our indebtedness on or before maturity. We may not be able to refinance any of our indebtedness on commercially reasonable terms or at all. Without this financing, we could be forced to sell assets or secure additional financing to make up for any shortfall in our payment obligations under unfavorable circumstances. However, we may not be able to secure additional financing on terms favorable to us or at all and, in addition, the terms of the indentures governing our notes limit our ability to sell assets and also restrict the use of proceeds from such a sale. We may not be able to sell assets quickly enough or for sufficient amounts to enable us to meet our obligations, including our obligations under our notes.

We maintain our cash and cash equivalents at financial institutions in amounts in excess of insured limits.

We maintain the majority of our cash and cash equivalents in accounts with U.S. and multi-national financial institutions, and our deposits at certain of these institutions, including the counterparty to our Swap Agreement, exceed insured limits. Market conditions can affect the viability of these institutions. In the event of failure of any of the financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we would be able to access uninsured funds in a timely manner or at all. Any inability to access or delay in accessing these funds could adversely affect our business and financial position.

ITEM 2. PROPERTIES

As part of the acquisition of the Sprint Business, we acquired a portfolio of owned and leased properties totaling approximately 1.9 million square feet. The properties are made up of technical facilities in the United States, including core switch facilities, PoP sites, regeneration and fiber pass through locations as well as warehouse buildings that support the acquired Sprint Network. Since the acquisition closing, we have added 52 major Sprint Data Centers and 55 smaller Edge Data Centers to our existing 52 Cogent Data Center portfolio (down from 55 at close); growing our data center portfolio to 159 buildings. We have also added 3 office buildings, 5 Carrier Neutral Data Centers and converted 36 nodes located in Carrier Neutral Data Centers to the Cogent network.

We lease space for offices, data centers, colocation facilities, and PoPs. We lease a total of approximately 1.0 million square feet of space for our data centers, offices and operations centers. Certain of these leases are with entities controlled by our Chief Executive Officer.

We believe that our facilities, both owned and leased are generally in good condition. Our leased properties and the vast majority of our owned properties are generally suitable for our operations, and we are in the process of repurposing any owned properties as necessary.

Our headquarters facility consists of 43,117 square feet located in Washington, D.C. The lease for our headquarters is with an entity controlled by our Chief Executive Officer and expires in May 2025. The lease may be cancelled by us upon 60 days’ notice.

On January 6, 2023, we entered into two lease agreements (the “New Leases”), one with Thorium LLC (“Thorium”) and one with Germanium LLC (“Germanium”), entities owned by our Chief Executive Officer and Chairman, David Schaeffer. The first of the New Leases is with Thorium for approximately 54,803 square feet of office space, which serves as office space replacing a portion of its office space in the Northern Virginia area.. The second of the New Leases is with Germanium LLC for approximately 1,587 square feet of technical space which serves as network operations space (“Network Operations Lease”). The term for each of the New Leases is five years beginning on April 1, 2023. Both of the New Leases are cancellable by us without penalty upon 60 days written notice. We took occupancy of the office space and network operations space in April 2023. We are responsible for paying our proportionate share of the building’s operating expenses that exceed a 2023 base year and we are also responsible for paying our metered utility costs and a proportionate share of the building’s other operating expenses that exceed a 2023 base year.

On July 25, 2023 we entered into a Second Amendment to the lease agreement with Germanium (the “Amendment”), which amended the Network Operations Lease to lease an additional 7,369 square feet on the first floor of the building, beginning on August 1, 2023, in connection with the planned expansion of the technical space. This included 4,987 square feet for an auditorium suitable for training and 2,382 square feet for the data center in the building. The amended Network Operations Lease remains cancellable by us without penalty upon 60 days written notice. The Amendment provides for $162,118 of additional fixed annual rent during the term of the Network Operations Lease, plus a proportionate share of real estate taxes and operating expenses and separately metered utilities expense.

ITEM 3. LEGAL PROCEEDINGS

We are involved in legal proceedings in the ordinary course of our business that we do not expect to have a material adverse effect on our business, financial condition or results of operations.

Factors that could cause or contribute to these differences include those discussed in “Item 1A. Risk Factors,” as well as those discussed elsewhere. You should read “Item 1A. Risk Factors” and “Special Note Regarding Forward-Looking Statements.” Our actual results could differ materially from those discussed here. Factors that could cause or contribute to these differences include, but are not limited to:

Our acquisition of Sprint Communications (as defined below), including difficulties integrating our business with the Sprint Business, which may result in the combined company not operating as effectively and efficiently as expected; transition services required to support the Sprint Business and the related costs continuing for a period longer than expected, the COVID-19 pandemic and accompanying government policies worldwide; vaccination and in-office requirements, delays in the delivery of network equipment or optical fiber, loss of key right-of-way agreements, future economic instability in the global economy, including the risk of economic recession and recent bank failures and liquidity concerns at certain other banks, which could affect spending on Internet services; the impact of changing foreign exchange rates (in particular the Euro to US dollar and Canadian dollar to US dollar exchange rates) on the translation of our non-US dollar denominated revenues, expenses, assets and liabilities into US dollars; legal and operational difficulties in new markets; the imposition of a requirement that we contribute to the US Universal Service Fund on the basis of our Internet revenue; changes in government policy and/or regulation, including rules regarding data protection, cyber security and net neutrality; increasing competition leading to lower prices for our services; our ability to attract new customers and to increase and maintain the volume of traffic on our network; the ability to maintain our Internet peering and right-of-way arrangements on favorable terms; our ability to renew our long-term leases of optical fiber and right-of-way agreements that comprise our network; our reliance on a limited number of equipment vendors, and the potential for hardware or software problems associated with such equipment; tariffs imposed on equipment we purchase for our network; the dependence of our network on the quality and dependability of third-party fiber and right-of-way providers; our ability to retain certain customers that comprise a significant portion of our revenue base; the management of network failures and/or disruptions; our ability to make payments on our indebtedness as they become due and outcomes in litigation, risks associated with variable interest rates under our Swap Agreement as well as other risks discussed from time to time in our filings with the Securities and Exchange Commission, including, without limitation, this Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q.

Acquisition of Sprint Communications

On May 1, 2023 (the “Closing Date”), Cogent Infrastructure, Inc. (now Cogent Infrastructure, LLC), a Delaware corporation and our direct wholly owned subsidiary (the “Buyer” or “Cogent Infrastructure”), closed on its acquisition of the U.S. long-haul fiber network (including the non-U.S. extensions thereof) of Sprint Communications and its subsidiaries (the “Sprint Business”) in accordance with the terms and conditions of the Membership Interest Purchase Agreement (the “Purchase Agreement”), dated September 6, 2022, by and among us, Sprint Communications LLC, a Kansas limited liability company (“Sprint Communications”) and an indirect wholly owned subsidiary of T-Mobile US, Inc., a Delaware corporation (“T-Mobile”), and Sprint LLC, a Delaware limited liability company and an indirect wholly owned subsidiary of T-Mobile (the “Seller”). On the Closing Date, we purchased from the Seller all of the issued and outstanding membership interests (the “Purchased Interests”) of Wireline Network Holdings LLC, a Delaware limited liability company that, following an internal restructuring and divisive merger, held Sprint Communications’ assets and liabilities relating to the Sprint Business (such transactions contemplated by the Purchase Agreement, collectively, the “Transaction”).

Purchase Price

On the Closing Date, we consummated the Transaction pursuant to the terms of the Purchase Agreement, providing a purchase price of $1 payable to the Seller for the Purchased Interests, subject to customary adjustments, including working capital (the “Working Capital Adjustment”), as set forth in the Purchase Agreement. As consideration for the Purchased Interests, the Working Capital Adjustment (primarily related to acquired cash and cash equivalents of an estimated $43.4 million at the Closing Date in order to fund the international operations of the Sprint Business) resulted in us making a payment to the Seller of $61.1 million on the Closing Date. In April 2024, an additional Working Capital Adjustment of $5.0 million was paid to the Seller.

Page 33 of 96

Short-term Lease Payment

The Purchase Agreement provides for a payment of $28.1 million ($19.8 million net of discount) from the Seller to us related to acquired short - term operating lease obligations (the “Short - term Lease Payment”). The Short - term Lease Payment will be paid from the Seller to us in four equal payments in months 55 to 58 after the Closing Date. The final determination of the Short - term Lease Payment was completed in April 2024. The Short - term Lease Payment was recorded at its present value resulting in a discount of $8.4 million. The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, among other market factors. The determination of the discount rate requires some judgment. During the third quarter of 2023, the Short - term Lease Payment was reduced by $4.8 million and in the first quarter of 2024 the Short - term Lease Payment, net of discount, was reduced by an additional $17.0 million.

IP Transit Services Agreement

On the Closing Date, we entered into an agreement for IP transit services (“IP Transit Services Agreement”), pursuant to which TMUSA will pay us an aggregate of $700.0 million, consisting of (i) $350.0 million in equal monthly installments of $29.2 million per month during the first year after the Closing Date and (ii) $350.0 million in equal monthly installments of $8.3 million per month over the subsequent 42 months. Under the IP Transit Services Agreement., TMUSA paid us $204.2 million and $204.2 million during the years ended December 31, 2024 and 2023, respectively.

We accounted for the Transaction as a business combination under ASC Topic 805 Business Combinations (“ASC 805”). We evaluated what elements are part of the business combination and the consideration exchanged to complete the acquisition. Under ASC 805, we concluded that the $700.0 million of payments to be made represent consideration received from T-Mobile to complete the acquisition of a distressed business. We also evaluated whether the IP Transit Services Agreement was in the scope of ASU No. 2014-09 Revenue from Contracts with Customers (“ASC 606”). We concluded that T-Mobile did not represent a “customer” as defined by ASC 606, the stated contract price did not represent consideration for services to be delivered, and the transaction did not satisfy the definition of revenue, which excluded this arrangement from the scope of ASC 606. As a result, and considering statements made by T-Mobile, the IP Transit Services Agreement was recorded in connection with the Transaction at its discounted present value resulting in a discount of $79.6 million. The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, amongst other market factors. The determination of the discount rate requires some judgment.

Transition Services Agreement

On the Closing Date, the Buyer entered into a transition services agreement (the “TSA”) with the Seller, pursuant to which the Seller provides to the Buyer, and the Buyer provides to the Seller on an interim basis following the Closing Date, certain specified services (the “Transition Services”) to ensure an orderly transition following the separation of the Sprint Business from Sprint Communications. The services provided by the Seller to the Buyer include, among others, information technology support, back office and finance, real estate and facilities, vendor and supply chain management, including the payment and processing of vendor invoices for the Company and human resources. The services provided by the Buyer to the Seller include, among others, information technology and network support, finance and back office and other wireless business support.

The Transition Services are generally intended to be provided for a period of up to two years following the Closing Date, although such period may be extended for an additional one-year term by either party upon 30 days’ prior written notice. The fees for the Transition Services are calculated using either a per service monthly fee or an hourly rate for the employees allocated to provide such services. Any third-party costs incurred in providing the Transition Services are passed on to the party receiving such services at cost for the two-year period. Amounts paid for the Sprint Business by T-Mobile are reimbursed at cost.

Either party to the TSA may terminate the agreement with respect to any individual service in full for convenience upon 30 days’ prior written notice for certain services and reduced for other services after a 90-day period. The TSA may be terminated in its entirety if the other party has failed to perform any of its material obligations and such failure is not cured within 30 days. The TSA provides for customary indemnification and limits on liability. Amounts billed under the TSA are due 30 days from receipt of the related invoice. Amounts billed to us under the TSA are primarily for reimbursement at cost of payments to vendors of the Sprint Business until these vendors are fully transitioned to us.

​

Page 34 of 96

During the years ended December 31, 2024 and 2023, we were billed $27.2 million and $284.1 million, respectively, as due to the Seller under the TSA. During the years ended December 31, 2024 and 2023, we paid to the Seller $93.8 million and $217.2 million, respectively, under the TSA. Amounts billed under the TSA are due 30 days from receipt of the related invoice. As of December 31, 2024 and December 31, 2023, we owed $0.5 million and $66.9 million, respectively, to the Seller under the TSA. During the years ended December 31, 2024 and 2023, we billed the Seller $1.1 million and $6.2 million, respectively, as due from the Seller under the TSA. During the years ended December 31, 2024 and 2023, the Seller paid us $1.3 million and $6.0 million, respectively, under the TSA. As of December 31, 2024 and 2023, the Seller owed us $0.1 million and $4.5 million, respectively, under the TSA.

Severance reimbursement

The Purchase Agreement also provides for reimbursement from the Seller to the Buyer for qualifying severance expenses incurred. Total qualifying severance expenses were $28.6 million of which $12.3 million and $16.2 million were recorded during the years ended December 31, 2024 and 2023, respectively, and fully reimbursed by the Seller.

Acquisition-Related Costs

In connection with the Transaction and negotiation of the Purchase Agreement, we incurred a total of $13.6 million of professional fees and other acquisition related costs (not including severance costs). Acquisition related costs (not including severance costs) were $9.1 million, $2.3 million and $2.2 million for the years ended December 31, 2024, 2023 and 2022, respectively.

Other Services Provided to the Seller

In addition, on the Closing Date, we entered into a commercial agreement (the “CSA”) with TMUSA for colocation and connectivity services, pursuant to which we provide such services to TMUSA for a per service monthly fee plus certain third-party costs incurred in providing the services. Under the CSA, we recorded service revenue of $14.7 million and $23.9 million during the years ended December 31, 2024 and 2023, respectively.

Results of Operations

Year Ended December 31, 2024 Compared to the Year Ended December 31, 2023

In this section, we discuss the results of our operations for the year ended December 31, 2024 compared to the year ended December 31, 2023. For a discussion of the year ended December 31, 2023 compared to the year ended December 31, 2022, please refer to Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2023.

Our management reviews and analyzes several key financial measures in order to manage our business and assess the quality and variability of our service revenue, operating results and cash flows. The following summary tables present a comparison of our results of operations with respect to certain key financial measures. The comparisons illustrated in the tables are discussed in greater detail below.

Page 35 of 96

Service Revenue. We continually work to grow our total service revenue by increasing the number of potential customers that we can reach on our network. We do this by investing capital to expand the geographic footprint of our network, increasing the number of buildings that we are connected to, including CNDCs and MTOBs, and increasing our penetration rate into our existing buildings. These efforts broaden the global reach of our network and increase the size of our potential addressable market. We also seek to grow our service revenue by investing in our sales and marketing team. We typically sell corporate connections at similar pricing to our competitors, but our customers benefit from our significantly faster speeds, greater aggregate throughput, enhanced service level agreements and rapid installation times. In the net-centric market, we offer comparable services in terms of capacity but typically at significantly lower prices.

Our service revenue increased by 10.1% from the year ended December 31, 2023 to the year ended December 31, 2024. Exchange rates negatively impacted our service revenue by $0.3 million. All foreign currency comparisons herein reflect results for the year ended December 31, 2024 translated at the average foreign currency exchange rates for the year ended December 31, 2023. Our total service revenue increased primarily due to the revenue acquired in May 2023 with the Sprint Business and the growth in customers from expanding our network, adding additional buildings to our network, increasing our penetration into the buildings connected to our network and gaining market share by offering our services at lower prices than our competitors. These increases were partially offset by the cancellation of low margin and non-core customers we acquired with the Sprint Business, and a reduction in revenue under our CSA agreement with TMUSA.

Revenue recognition standards include guidance relating to any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between a seller and a customer and may include, but is not limited to, gross receipts taxes, Universal Service Fund fees and certain state regulatory fees. We record these taxes billed to our customers on a gross basis (as service revenue and network operations expense) in our consolidated statements of comprehensive income. The impact of these taxes including the Universal Service Fund resulted in an increase to our revenues of $30.2 million from the year ended December 31, 2023 to the year ended December 31, 2024.

Revenue and customer connections by customer type. Our corporate customers generally purchase their services on a price per connection basis. Our net-centric customers generally purchase their services on a price per megabit-metered basis. Our enterprise customers generally purchase our services on a price per location basis. We began to serve enterprise customers in connection with our acquisition of the Sprint Business. We define “enterprise” customers as large corporations (typically, Fortune 500 companies with greater than $5 billion in annual revenue) running Wide Area Networks (“WAN”) with several dozen to several hundred sites.

We believe that we are in a unique position to monetize the Sprint Business and its network and management expects to achieve significant cost reduction synergies and revenue synergies from the Transaction. Revenue and pre-tax loss for the Sprint Business included in our consolidated statements of comprehensive income for the year ended December 31, 2023 were $283.3 million and $234.5 million, respectively.

On the Closing Date, we acquired 17,823 corporate customer connections, 5,711 net-centric customer connections and 23,209 enterprise customer connections with the Sprint Business. We classified the total $39.4 million of May 2023 Sprint Business monthly recurring revenue as $20.0 million of enterprise revenue, $12.9 million of corporate revenue and $6.5 million of net-centric revenue.

Revenues from our corporate, net-centric and enterprise customers represented 45.7%, 35.6% and 18.7% of total service revenue, respectively, for the year ended December 31, 2024 and represented 47.2%, 36.5% and 16.3% of total service revenue, respectively, for the year ended December 31, 2023.

Our revenue from our corporate customers increased primarily due to customers acquired with the Sprint Business. Our corporate customers take advantage of our superior speeds, greater aggregate throughput, service levels and installation times versus our competitors. The growing trend of customers installing second lines for redundancy in order to construct virtual private networks (“VPNs”) has also led to our ability to increase our corporate revenues. Beginning with and throughout the COVID-19 pandemic, we witnessed a deteriorating real estate market in and around the buildings we service in central business districts in North America. Because of the rising vacancy levels and falling lease initiations or renewals, we experienced a slowdown in new sales to our corporate customers, which negatively affected our corporate revenue results. During the year ended December 31, 2024, we continued to see gradual declines in vacancy rates and rising office occupancy rates. As the option to fully or partially work from home becomes permanently established at many companies, our corporate customers are integrating some of the new applications that became part of the remote work environment, which benefits our corporate business as these customers upgrade their Internet access infrastructure to higher capacity connections. Further, if and when companies eventually return to the buildings in which we operate, we believe it will present an opportunity for increased sales. However, the exact timing and path of these positive trends remains uncertain.

Our revenue from our net-centric customers increased primarily due to growth in network traffic from our legacy net-centric customers and from net-centric customers acquired with the Sprint Business. Our net-centric customers purchase our services on a price per megabit basis. The net-centric market exhibits significant pricing pressure due to the continued introduction of new technology, which lowers the marginal cost of transmission and routing, and the commodity nature of the service where price is typically the only differentiating factor for these customers. Our average price per megabit of our installed base of customers decreased by 14.2% from the year ended December 31, 2023 to the year ended December 31, 2024. The impact of foreign exchange rates has a more significant impact on our net-centric revenues. Under our CSA with TMUSA, we recorded net-centric service revenue of $14.7 million and $23.9 million during the years ended December 31, 2024 and 2023, respectively.

Our revenue from our enterprise customers increased primarily due to customers acquired with the Sprint Business.

Revenue and customer connections by network connection type. On the Closing Date, we classified the total $39.4 million of monthly Sprint Business revenue as $2.5 million of on-net revenue, $32.2 million of off-net revenue and $4.7 million of non-core revenue. Additionally, on the Closing Date, we classified the total 46,743 Sprint Business customer connections as 1,560 on-net customer connections, 24,667 off-net customer connections and 20,516 non-core customer connections.

Revenues from our on-net, off-net, wavelength and non-core customers represented 52.6%, 43.8%, 1.9% and 1.7% of total service revenue, respectively, for the year ended December 31, 2024 and represented 54.5%, 41.8%, 0.6% and 3.1% of total service revenue, respectively, for the year ended December 31, 2023.

Page 37 of 96

Our on-net revenues increased from the year ended December 31, 2023 to the year ended December 31, 2024 primarily from customers acquired with the Sprint Business and an increase in revenues from our legacy Cogent customers. Under the CSA with TMUSA, we recorded on-net service revenue of $14.0 million and $21.6 million during the years ended December 31, 2024 and 2023, respectively. Our off-net revenues increased from the year ended December 31, 2023 to the year ended December 31, 2024 primarily from customers acquired with the Sprint Business and an increase in revenues from our legacy Cogent customers.

In connection with our acquisition of the Sprint Business, we expanded our offerings of optical wavelength and optical transport services over our fiber network. Our wavelength revenue was $19.2 million for the year ended December 31, 2024 and was $5.7 million for the year ended December 31, 2023.

Our non-core revenues decreased from the year ended December 31, 2023 to the year ended December 31, 2024 primarily due to the cancellation of non-core revenues acquired in the Sprint Business. Non-core services are services, that we acquired and continue to support but do not actively sell.

Network Operations Expenses. Network operations expenses include the costs of personnel associated with service delivery, network management and customer support, network facilities costs, right-of-way fees, fiber and equipment maintenance fees, leased circuit costs, access and facilities fees paid to building owners and excise taxes billed to our customers and recorded on a gross basis. Non-cash equity-based compensation expense is included in network operations expenses consistent with the classification of the employee’s salaries and other compensation. Our 17.9% increase in network operations expense was primarily attributable to an increase in network operations expense from our acquisition of the Sprint Business and an increase in costs related to our network and facilities expansion activities.

Selling, General, and Administrative (“SG&A”) Expenses. Our SG&A expenses, including non-cash equity-based compensation expense, increased by 0.2% from the year ended December 31, 2023 to the year ended December 31, 2024. Non-cash equity-based compensation expense is included in SG&A expenses consistent with the classification of the employee’s salary and other compensation. SG&A expenses increased primarily from an increase in salaries and benefits from 942 employees added to our headcount from our acquisition of the Sprint Business on the Closing Date and costs associated with the Sprint acquisition including TSA costs. Our total headcount was 1,916 at December 31, 2024 and 1,947 at December 31, 2023.

Acquisition-Related Costs. In connection with the Transaction and negotiation of the Purchase Agreement, we incurred professional fees, and other acquisition related costs totaling $42.1 million, including $28.6 million of reimbursed severance costs. Such fees totaled $21.4 million for the year ended December 31, 2024 and $18.5 million for the year ended December 31, 2023.

Depreciation and Amortization Expenses. Our depreciation and amortization expense increased by 28.3% primarily due to the depreciation expense associated with assets acquired with the Sprint Business and an increase in deployed fixed assets, partly offset by the impact of an increase in the estimated useful life for our owned fiber acquired with the Sprint Business. Effective July 1, 2024, we changed our estimate of the useful life of our owned fiber to better reflect the estimated periods during which these assets will remain in service. The estimated useful life of the owned fiber that previously averaged 14 years was increased to an average of 40 years. The effect of this change in estimate on the year ended December 31, 2024 was to reduce depreciation expense by $8.7 million.

Gain on Lease Termination. In June 2024, we elected to exercise a contractual option to prepay in full at a 12.0% discounted rate an IRU finance lease agreement between us and a vendor we assumed with the Sprint Business for $114.6 million. At the payment date, the present value of the IRU finance lease liability was $117.9 million and the remaining thirty-one $4.2 million monthly principal payments totaled $130.2 million. The prepayment resulted in a gain on lease termination of $3.3 million related to the difference between the book value of $117.9 million and the cash payment of $114.6 million. We are continuing to use the related IRU asset.

Gain on Bargain Purchase. We accounted for our acquisition of the Sprint Business as a business combination. The identifiable assets acquired and liabilities assumed were recorded at their fair values as of the acquisition date. Assigning fair market values to the assets acquired and liabilities assumed at the date of an acquisition requires the use of significant judgment regarding estimates and assumptions. As of December 31, 2023, the fair value of the identifiable assets acquired was $1.9 billion (including amounts due under the IP Transit Services Agreement) and was in excess of the $0.9 billion liabilities assumed and the $0.6 billion net consideration to be received from the Seller resulting in a gain on bargain purchase of $1.4 billion. During the year ended December 31, 2024, we made certain adjustments to our estimates of the fair market value of the assets acquired and liabilities assumed resulting in an increase to the gain on bargain purchase of $22.2 million for the year ended December 31, 2024. The total bargain purchase gain from the Transaction was $1.4 billion.

Interest Income - IP Transit Services Agreement. Under the IP Transit Services Agreement, TMUSA will pay us an aggregate of $700.0 million, consisting of (i) $350.0 million in equal monthly installments during the first year after the Closing Date and (ii) $350.0 million in equal monthly installments over the subsequent 42 months. The IP Transit Services Agreement was recorded in connection with the Transaction at its discounted present value resulting in a discount of $79.6 million. The amortization of the discount is recorded as interest income.

Interest Expense - Including Change in Valuation of Swap Agreement. Our interest expense resulted from interest incurred on our 2026 Notes, 2027 Notes, 2027 Mirror Notes, IPv4 Notes, Swap Agreement and finance lease obligations.

As of December 31, 2024, the fair value of our Swap Agreement was a net liability of $22.3 million. Changes in the valuation of the Swap Agreement are related to semi-annual interest payments in May and November and changes in interest rates, and are included in interest expense. Under the Swap Agreement settlement payments made in May 2023 and November 2023, we paid a total of $21.5 million to the counterparty for a net cash interest cost of $21.5 million for the year ended December 31, 2023. Under the Swap Agreement settlement payments made in May 2024 and November 2024, we paid a total of $24.2 million to the counterparty for a net cash interest cost of $24.2 million for the year ended December 31, 2024. Our interest expense increased by 32.1% primarily due to the issuance of our IPv4 Notes in May 2024, the issuance of our 2027 Mirror Notes in June 2024 and the increase in payments under our Swap Agreement.

Income Tax Benefit. Our income tax benefit was $55.6 million for the year ended December 31, 2024 and $54.0 million for the year ended December 31, 2023. The change in our income tax benefit was primarily related to projected operating results related to the Sprint Business acquisition and the reversal of deferred tax liabilities acquired with the Sprint Business.

Buildings On-net. As of December 31, 2024 and 2023, we had a total of 3,453 and 3,277 on-net buildings connected to our network, respectively. The increase in our on-net buildings was a result of our disciplined network expansion program. We anticipate adding a similar number of buildings to our network for the next several years.

Liquidity and Capital Resources

Acquisition of Sprint Communications

The Sprint Business’s cash flow was negative at the time of negotiations and during its recent history. Due to the dire financial condition of the Sprint Business, it was understood that a payment from T-Mobile to any potential buyer would be required to execute a transaction to give a buyer sufficient cash inflow to offset losses that would be expected until a buyer could optimize the business. Based on management’s internal modeling at the culmination of the due diligence process, management determined this cash payment to be $700.0 million. Management is reducing the negative cash flow of the Sprint Business through the payments from the IP Transit Services Agreement, reducing operating costs and increasing revenue primarily by providing optical wavelength and optical transport services over our fiber network, including the owned network we acquired with the Sprint Business. We are selling these services to our existing customers, customers we acquired with the Sprint Business and to new customers who require dedicated optical transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure. As part of the Transaction, we began incurring costs associated with the TSA. The amount of these costs will be dependent upon our ability to integrate the operations of the Sprint Business into our operations. Our cash flow requirements related to the acquisition of the Sprint Business will be dependent upon our ability to reduce the acquired operating costs, our success in retaining the acquired customers and our ability to sell optical wavelength and optical transport services over our fiber network.

Under the IP Transit Services Agreement, TMUSA will pay us an aggregate of $700.0 million, consisting of (i) $350.0 million in equal monthly installments of $29.2 million per month during the first year after the Closing Date and (ii) $350.0 million in equal monthly installments of $8.3 million per month over the subsequent 42 months. Through December 31, 2024, we received monthly payments totaling $408.3 million under the IP Transit Services Agreement, reflected as cash flows from investing activities in our consolidated statements of cash flows. As our business has grown as a result of an increasing customer base, the Transaction, broader geographic coverage and increased traffic on our network, we have historically produced a growing level of cash provided by operating activities. Since we closed the Transaction, we experienced a reduction of cash provided by operating activities from the impact of the Transaction. The cash received from the IP Transit Services Agreement was designed to offset operating losses associated with the Sprint Business. Increasing our cash provided by operating activities is, in part, dependent upon our ability to reduce the operating costs of the Sprint Business while retaining its profitable revenue, expanding our geographic footprint and increasing our network capacity.

Page 39 of 96

During 2025, we expect to receive a total of $100.0 million under the monthly payments under the IP Transit Services Agreement. This includes 12 monthly payments of $8.3 million each. Increasing our cash provided by operating activities, is in part, dependent upon our ability to reduce the operating costs of the Sprint Business while retaining its profitable revenue.

In assessing our liquidity, management reviews and analyzes our current cash balances, payments under the IP Transit Services Agreement, accounts receivable, accounts payable, accrued liabilities, capital expenditure commitments, and required finance lease and debt payments and other obligations. Because of the operating leverage of our network, our annual capital expenditures measured as a percentage of revenues has fallen over the last decade but increased in 2024 to 18.8% from 13.8% for 2023, primarily due to capital expenditures related to our acquisition of the Sprint Business, costs associated with providing wave services, conversion costs related to acquired data centers and adding buildings to our network.

To date, we have been able to raise capital by issuing notes and arranging financing and leases that have had more flexible terms at reasonable cost. Through our issuance of the IPv4 Notes, we have also been able to access new markets for raising capital. The combination of this improved operating performance and access to capital has preserved our financial flexibility and buttressed our ability to make distributions to stockholders in the form of cash dividends or through share repurchases. We have returned $1.6 billion to our stockholders through share repurchases and dividends. We will continue to assess our capital and liquidity needs and, where appropriate, return capital to stockholders.

Over the next several years, we have significant contractual and anticipated cash outlays, including our indicative dividend payments on our common stock, our maturing debt obligations, interest payments on our debt obligations and Swap Agreement and our projected capital expenditure requirements in order to help execute our business plan, including the integration of Sprint Business. Based upon the historical growth rate of our dividend, we expect that we would have to provide approximately $399 million in order to meet our expected quarterly dividend payments over the next two years. Our $500.0 million of 2026 Notes accrue interest at 3.50%, mature in May 2026 and include annual interest payments of $17.5 million until maturity. Our $450.0 million of 2027 Notes mature in June 2027 and include annual interest payments of $31.5 million until maturity. Our $300.0 million of 2027 Mirror Notes mature in June 2027 and include annual interest payments of $21.0 million until maturity. Our $206.0 million of IPv4 Notes effectively mature in May 2029 and include annual interest payments of $16.3 million until maturity (which amount increases if the IPv4 Notes are not repaid prior to May 2029).

Under our Swap Agreement, we pay the counterparty a semi-annual payment based upon overnight SOFR plus a contractual interest rate spread, and the counterparty pays us a semi-annual fixed 3.50% interest payment. These settlement payments are made in November and May of each year until the Swap Agreement expires in February 2026. As of December 31, 2024, $22.3 million of our cash and cash equivalents are restricted for use under our Swap Agreement. We have made a $23.4 million deposit with the counterparty to the Swap Agreement. If the fair value of the Swap Agreement exceeds a net liability of $23.4 million, we will be required to deposit additional funds with the counterparty equal to the liability fair value.

In June 2024, we elected to exercise a contractual option to prepay in full at a 12.0% discount rate an IRU finance lease agreement between us and a vendor we assumed with the Sprint Business for $114.6 million. At the payment date, the present value of the IRU finance lease liability was $117.9 million and the remaining thirty-one $4.2 million monthly principal payments totaled $130.2 million. The prepayment resulted in a gain on lease termination of $3.3 million related to the difference between the book value of $117.9 million and the cash payment of $114.6 million. We are continuing to use the related IRU asset.

We may need to, or elect to, refinance all or a portion of our indebtedness at or before maturity, and we cannot provide assurances that we will be able to refinance any such indebtedness on commercially reasonable terms or at all. In addition, we may elect to secure additional capital in the future, at acceptable terms, to improve our liquidity or fund acquisitions or for general corporate purposes. In addition, in an effort to reduce future cash interest payments as well as future amounts due at maturity or to extend debt maturities, we may, from time to time, issue new debt, enter into interest rate swap agreements, enter into debt for debt, or cash transactions to purchase our outstanding debt securities in the open market or through privately negotiated transactions. We will evaluate any such transactions in light of the existing market conditions. The amounts involved in any such transaction, individually or in the aggregate, may be material. We or our affiliates may, at any time and from time to time, seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

In light of the economic uncertainties associated with the global economy, evolving hybrid work arrangements, the cash flow requirements of the Sprint Business, and the uncertain impact of proposed changes to economic and fiscal policies in the United States and other countries, our executive officers and Board of Directors have continued to carefully monitor our liquidity and cash

Page 40 of 96

requirements as well as our capital spending. After consideration of these circumstances, we currently plan to continue our current dividend policy. As we do each year, we will continue to monitor our future sources and uses of cash, and anticipate that we will adjust our capital allocation strategies when, as and if determined by our Board of Directors.

As of December 31, 2024, we had cash, cash equivalents and restricted cash of $227.9 million. The COVID-19 pandemic has not impacted our credit rating to date, nor do we believe that it has materially changed our cost of capital. We believe we are able to timely service our debt obligations and will not require any concessions to do so. We believe we will have access to additional capital from a variety of sources and the public capital markets for debt and equity.

Continued Impact of Changing Office Occupancy Rates

Since the onset of the COVID-19 pandemic in 2020, we have experienced certain corporate customers taking a more cautious approach to new configurations and upgrades as well as a reduction in demand for connecting smaller satellite offices as a result of the challenges and uncertainties of the remote work environment that resulted initially from the pandemic. We also witnessed a deteriorating real estate market in and around the buildings we service with rising vacancy levels and falling lease initiations or renewals, which resulted in fewer sales opportunities for our salesforce and a reduction in VPN opportunities. As a result, we experienced a slowdown in new sales to our corporate customers, which negatively impacted our corporate revenue growth.

During the year ended December 31, 2024, we continued to see declining vacancy rates compared to their peak during the pandemic and rising office occupancy rates in certain markets in which we operate continuing a trend that began following the end of the pandemic. Other markets, particularly those in California, Washington D.C. and the Pacific Northwest, continue to see markedly higher vacancy rates. These higher vacancy rates may represent a long-term change in office attendance and occupancy rates in these markets. Despite this overall environment, we are seeing some positive trends in our corporate business. This was partially due to the increase in office occupancy rates and leasing activity in some markets but also due to new demands for services from corporate customers. As the option to fully or partially work from home becomes permanently established at many companies, our corporate customers are integrating certain new applications that became part of the remote work environment, which benefits our corporate business as these customers upgrade their Internet access infrastructure to higher capacity connections, and mitigates the overall impact of remote work policies on our corporate business. Further, if and when companies eventually return to the buildings in which we operate, whether as existing or new tenants, we believe it will present an opportunity for increased sales.

While we believe that demand for office space in the buildings in which we operate will remain among the strongest in the markets in which they are located, and that most employers will eventually require their employees to return to their offices on at least a hybrid basis, the timing and scope of a return to office, particularly in a number of key markets we serve, remains uncertain. In some markets, office occupancy rates may never return to pre-2020 levels. As a result, we may continue to experience increased customer turnover, fewer upgrades of existing customer configurations and fewer new tenant opportunities. These trends may negatively impact our revenue growth, cash flows and profitability.

Cash Flows

The following table sets forth our consolidated cash flows.

​

​

Net Cash (Used in) Provided by Operating Activities. Our primary source of operating cash is receipts from our customers who are billed on a monthly basis for our services. Our primary uses of operating cash are payments made to our vendors, payments made under the TSA, payments to employees and interest payments made to our finance lease vendors and our note holders. Our changes in cash provided by operating activities are primarily due to changes in net payments under the TSA, changes in our operating profit and changes in our interest payments.

Page 41 of 96

On the Closing Date, we entered into a TSA with the Seller, pursuant to which the Seller provides to us, and we provide to the Seller on an interim basis following the Closing Date, Transition Services to ensure an orderly transition following the separation of the Sprint Business from Sprint Communications. Amounts billed under the TSA are due 30 days from receipt of the related invoice. During 2024 and 2023, we were billed $27.2 million and $284.1 million, respectively, under the TSA, primarily for reimbursement at cost of payments to vendors of the Sprint Business. During 2024 and 2023 we paid $93.8 million and $217.2 million to the Seller under the TSA, respectively. Amounts recorded and paid as due to the Seller under the TSA resulted in a use of cash in operating activities of $66.4 million for 2024 and contributed $66.9 million to net cash provided by operating activities for 2023.

Net Cash Provided by (Used in) Investing Activities. Our primary use of cash for investing activities is for purchases of property and equipment. Purchases of property and equipment were $195.0 million, $129.6 million and $79.0 million for 2024, 2023 and 2022, respectively. The changes in purchases of property and equipment were primarily due to the timing and scope of our network expansion activities including geographic expansion, purchases related to our acquisition of the Sprint Business, costs associated with providing wave services, conversion costs related to acquired data centers and adding buildings to our network.

Our primary source of cash provided by investing activities is our IP Transit Services Agreement with TMUSA. On the Closing Date, we entered into the IP Transit Services Agreement pursuant to which TMUSA will pay us an aggregate of $700.0 million, consisting of (i) $350.0 million in equal monthly installments during the first year after the Closing Date and (ii) $350.0 million in equal monthly installments over the subsequent 42 months. During 2024 and 2023 we were paid $204.2 million and $204.2 million under the IP Transit Services Agreement, respectively. In May 2023 we paid $61.1 million and acquired $47.1 million of cash and in 2023 we paid $5.0 million related to our acquisition of the Sprint Business. In 2024 and 2023 we received $12.3 million and $16.2 million of reimbursed severance payments, respectively, related to our acquisition of the Sprint Business. We received a combined net total of $14.5 million of cash received (including reimbursed severance payments) related to our acquisition of the Sprint Business.

Net Cash Provided by (Used in) Financing Activities. Our primary uses of cash for financing activities are for dividend payments, principal payments under our finance lease obligations and purchases of our common stock. Our primary sources of cash for financing activities are issuances of note obligations. During 2024, 2023 and 2022, we paid $189.4 million, $181.7 million and $169.9 million, respectively, for our quarterly dividend payments. Our quarterly dividend payments have increased due to increases in our quarterly dividend per share amounts. Principal payments under our finance lease obligations were $74.6 million, $77.4 million and $45.5 million, respectively, In June 2024, we elected to exercise a contractual option to prepay in full at a 12.0% discount rate an IRU finance lease agreement between us and a vendor we assumed with the Sprint Business for $114.6 million. The other changes in our principal payments under our finance lease obligations were primarily due to the timing and extent of our network expansion activities including geographic expansion, purchases related to our acquisition of the Sprint Business, purchases associated with providing wave services and adding buildings to our network. During 2024, we purchased 153,322 shares of our common stock for $8.0 million. There were no purchases of our common stock in 2023 or 2022.

We completed a series of debt issuances and redemptions in 2024 and 2022.

On May 2, 2024, we issued $206.0 million aggregate principal amount of our IPv4 Notes, with an anticipated term ending in May 2029. The net proceeds from the offering, after debt offering costs, were $198.4 million. Interest on the IPv4 Notes is paid on a monthly basis. From and after May 2029, principal payments will also be required to be made on the IPv4 Notes on a monthly basis. No principal payments will be due on the IPv4 Notes prior to May 2029, unless certain rapid amortization or acceleration triggers are activated.

On June 11, 2024, Cogent Communications Group, LLC (“Group”) and Cogent Finance, Inc. (the “Co-Issuer” and, together with Group, the “Issuers”), two wholly owned subsidiaries of Cogent Communications Holdings, Inc. (“Holdings”), completed an offering of $300.0 million aggregate principal amount of our 2027 Mirror Notes. The 2027 Mirror Notes were issued at a price equal to 98.50% of their face value. The net proceeds from the offering were approximately $291.9 million after deducting the discount and offering expenses. The 2027 Mirror Notes bear interest at a rate of 7.00% per annum. Interest began to accrue on the 2027 Mirror Notes on June 11, 2024 and will be paid semi-annually in arrears on June 15 and December 15 of each year, commencing on December 15, 2024. Unless earlier redeemed or repurchased, the 2027 Mirror Notes will mature on June 15, 2027.

In June 2022, we paid $375.4 million to redeem and extinguish our 2024 Notes at 101.094% of par value, and we issued $450.0 million of our 2027 Notes for net proceeds of $446.0 million.

Page 42 of 96

Indebtedness

Our total cash, cash equivalents and restricted cash at December 31, 2024 were $227.9 million and our net accounts receivable were $96.9 million. We believe this level of liquidity reduces our exposure to refinancing risk, potential underperformance of the business or other unforeseen challenges and enhances our ability to pursue acquisitions or operating opportunities. We intend to hold levels of cash and cash equivalents sufficient to maintain our ability to fund operations and make dividend payments to our stockholders.

Our total indebtedness at December 31, 2024, at par value, was $2.0 billion. Our total indebtedness at December 31, 2024 includes $538.4 million of finance lease obligations for dark fiber under long-term IRU agreements.

Issuance of $300.0 Million Principal Amount of 2027 Mirror Notes

On June 11, 2024, the Issuers completed the offering of our 2027 Mirror Notes for issuance in a private placement not registered under the Securities Act. The 2027 Mirror Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers in an unregistered offering pursuant to Rule 144A under the Securities Act and to certain non - U.S. persons in transactions outside the United States in compliance with Regulation S under the Securities Act. The 2027 Mirror Notes have the same maturity date and call protection, bear interest at the same rate and otherwise have substantially the same terms as our 2027 Notes; however, the 2027 Mirror Notes are not fungible (from a trading or tax perspective) with the 2027 Notes and are a separate series of notes from the 2027 Notes.

The 2027 Mirror Notes were issued at a price equal to 98.50% of their face value. The net proceeds from the offering were approximately $291.9 million after deducting the discount and offering expenses. We used $114.6 million of the net proceeds from the offering to exercise a contractual option to prepay in full in June 2024 an existing IRU agreement consisting of 31 remaining monthly recurring payments of $4.2 million, at a 12.0% discount rate. We expect to use the remainder of the net proceeds for general corporate purposes and/or to make special or recurring dividends to Holdings.

The 2027 Mirror Notes were issued pursuant to, and are governed by, an indenture, dated June 11, 2024 (the “2027 Mirror Notes Indenture”), among the Issuers, Holdings, the other guarantors named therein and Wilmington Trust, National Association, as trustee (the “2027 Notes Trustee”). The 2027 Mirror Notes are jointly and severally guaranteed (the “Guarantees”) on a senior unsecured basis by each of Group’s existing and future material domestic subsidiaries (other than the Co-Issuer), subject to certain exceptions (collectively, the “Subsidiary Guarantors”), and by Holdings (together with the Subsidiary Guarantors, the “Guarantors”). However, the Holdings is not subject to the covenants under the 2027 Mirror Notes Indenture. Under certain circumstances, the Guarantors may be released from these Guarantees without the consent of the holders of the 2027 Mirror Notes.

The 2027 Mirror Notes and the Guarantees are the Issuers’ and the Guarantors’ senior unsecured obligations. The 2027 Mirror Notes and the Guarantees are effectively subordinated to all of the Issuers’ and the Guarantors’ existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness, and are structurally subordinated to all indebtedness and other liabilities of subsidiaries that are not Subsidiary Guarantors. Without giving effect to collateral arrangements, the 2027 Mirror Notes and the Guarantees rank pari passu in right of payment with all of the Issuers’ and the Guarantors’ existing and future senior indebtedness, including the 2026 Notes and the 2027 Notes. The 2027 Mirror Notes and the Guarantees rank contractually senior in right of payment to all of the Issuers’ and the Guarantors’ subordinated indebtedness and are structurally subordinated to any existing and future indebtedness and other liabilities of the Issuers’ non-guarantor subsidiaries.

The 2027 Mirror Notes bear interest at a rate of 7.00% per annum. Interest began to accrue on the 2027 Mirror Notes on June 11, 2024 is paid semi-annually in arrears on June 15 and December 15 of each year, which commenced on December 15, 2024. Unless earlier redeemed or repurchased, the 2027 Mirror Notes will mature on June 15, 2027. After June 15, 2024, the Issuers may redeem the 2027 Mirror Notes, in whole or in part, at a redemption price ranging from 103.5% of the aggregate principal amount of the 2027 Mirror Notes redeemed to par (depending on the year), in each case, as set forth in the 2027 Mirror Notes Indenture, plus accrued and unpaid interest, if any, to, but not including, the date of redemption.

If Group undergoes specific kinds of change in control accompanied by certain ratings events, the Issuers will be required to offer to repurchase the 2027 Mirror Notes from holders at a price equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase. Additionally, if Group or any of its restricted subsidiaries sells assets and does not apply the proceeds from such sale in a certain manner or certain other events have not occurred, under certain circumstances, we will be required to use the net proceeds to make an offer to purchase the 2027 Mirror Notes at an offer price in cash equal to 100% of the principal amount of the 2027 Mirror Notes, plus accrued and unpaid interest, if any, to, but not including, the

Page 43 of 96

repurchase date. In connection with any offer to purchase all or any of the 2027 Mirror Notes (including a change of control offer, asset sale offer or any tender offer), if holders of no less than 90% of the aggregate principal amount of the outstanding 2027 Mirror Notes validly tender their 2027 Mirror Notes, the Issuers, or a third party, are entitled to redeem any remaining 2027 Mirror Notes at the price paid to each holder.

The 2027 Mirror Notes Indenture includes covenants that restrict Group and its restricted subsidiaries’ (including the Co-Issuer’s) ability to, among other things: incur indebtedness; issue certain preferred stock or similar equity securities; pay dividends or make other distributions in respect of, or repurchase or redeem, capital stock; make certain investments and other restricted payments, such as prepayment, redemption or repurchase of certain indebtedness; create liens; consolidate, merge, sell or otherwise dispose of all or substantially all of the properties and assets of Group and its restricted subsidiaries taken as a whole; incur restrictions on the ability of a subsidiary to pay dividends or make other payments; or enter into transactions with affiliates. The covenants provide for certain exceptions to these restrictions, and Holdings is not subject to the covenants under the 2027 Mirror Notes Indenture. Certain covenants will cease to apply to the 2027 Mirror Notes if, and for so long as, the 2027 Mirror Notes have investment grade ratings from any two of Moody’s Investors Service, Inc., Fitch Ratings, Inc. and S&P Global Ratings, and so long as no default or event of default under the 2027 Mirror Notes Indenture has occurred and is continuing. Upon suspension of the covenants, the Guarantees will be released until such time as the covenants are no longer suspended.

The principal amount of the 2027 Mirror Notes would become immediately due and payable upon the occurrence of certain bankruptcy or insolvency events and may be declared immediately due and payable by the 2027 Notes Trustee or the holders of at least 25% of the aggregate principal amount of the then-outstanding 2027 Mirror Notes upon the occurrence of certain events of default under the 2027 Mirror Notes Indenture. Events of default include the following with respect to the Issuers’ and Group’s significant subsidiaries: (i) failure to pay principal, premium or interest at required times; (ii) failure to comply with any other agreements in the 2027 Mirror Notes Indenture; (iii) default on certain material indebtedness that is caused by a failure to make a payment within any applicable grace period when due at maturity or results in the acceleration of such indebtedness prior to its express maturity; (iv) failure to pay certain material judgments; (v) a Guarantee being held unenforceable or invalid or ceasing for any reason to be in full force and effect or a Guarantor denying or disaffirming its obligations under its Guarantee; and (vi) certain events of bankruptcy or insolvency.

Issuance of $206.0 Million Principal Amount of IPv4 Notes

On May 2, 2024, the IPv4 Issuer, our special-purpose, bankruptcy remote, indirect wholly owned subsidiary, issued $206.0 million aggregate principal amount of IPv4 Notes, with an anticipated term ending in May 2029 (such anticipated repayment date, the “ARD”), in an offering exempt from registration under the Securities Act. The net proceeds from the offering, after debt offering costs, were $198.4 million and are expected to be used for general corporate purposes.

The IPv4 Notes were issued pursuant to an indenture, dated as of May 2, 2024 (the “IPv4 Base Indenture”), as supplemented by the Series 2024-1 Supplement thereto, dated as of May 2, 2024 (the “Series 2024-1 Supplement”), in each case entered into by and between the IPv4 Issuer and Wilmington Trust, National Association, as the trustee for the IPv4 Notes (the “IPv4 Trustee”). The IPv4 Base Indenture allows the IPv4 Issuer to issue additional series of notes subject to certain conditions set forth therein, and the IPv4 Base Indenture, together with the Series 2024-1 Supplement, and any other series supplements to the IPv4 Base Indenture, is referred to herein as the “IPv4 Indenture.”

The IPv4 Notes were issued as part of a securitization transaction, pursuant to which certain Internet Protocol version 4 (“IPv4”) addresses, customer IPv4 address leases, customer accounts receivables and other IPv4 address assets (collectively, “IPv4 Address Assets”) were contributed or sold to the IPv4 Issuer and are included as collateral for the IPv4 Notes.

While the IPv4 Notes are outstanding, scheduled payments of interest are required to be made on a monthly basis. From and after the ARD, principal payments will also be required to be made on the IPv4 Notes on a monthly basis. No principal payments will be due on the IPv4 Notes prior to the ARD, unless certain rapid amortization or acceleration triggers are activated.

Cogent Communications LLC (in such capacity, the “Manager”) performs certain monthly services related to the IPv4 Address Assets and IPv4 Notes including billing customers, collecting amounts paid by customers, forwarding payments to the IPv4 Trustee related to the IPv4 Address Assets and other administrative services. Amounts paid by the Manager to the IPv4 Trustee are reconciled on a monthly basis and the IPv4 Trustee pays the monthly interest on the IPv4 Notes and other expenses from the accumulated customer payments on the IPv4 Address Assets. Amounts held by the IPv4 Trustee before the monthly reconciliation is completed are considered restricted cash. After the IPv4 Trustee pays the monthly interest and other IPv4 Address Asset related costs, including monthly fees paid to the Manager for its services, the residual cash is paid to us and is unrestricted.

Page 44 of 96

The legal final maturity date of the IPv4 Notes is in May of 2054. If the IPv4 Issuer has not repaid or refinanced the IPv4 Notes prior to the monthly payment date in May of 2029, additional interest will accrue thereon in an amount equal to the greater of (i) 5.0% per annum and (ii) the excess amount, if any, by which the sum of the following exceeds the interest rate for such IPv4 Note: (A) the yield to maturity (adjusted to a “mortgage-equivalent basis” pursuant to the standards and practices of the Securities Industry and Financial Markets Association) on the ARD for such IPv4 Note of the United States Treasury Security having a remaining term closest to 10 years; plus (B) 5.0%; plus (C) the post-ARD note spread of 3.400% applicable to such Note.

The IPv4 Notes are obligations only of the IPv4 Issuer pursuant to the IPv4 Indenture, and are secured by a security interest in substantially all of the IPv4 Address Assets pursuant to the IPv4 Indenture. The IPv4 Notes are guaranteed by Cogent IPv4 Holdco LLC, a special-purpose entity and our indirect wholly owned subsidiary, as the guarantor (the “IPv4 Guarantor”), pursuant to a guaranty dated as of May 2, 2024 (the “Guaranty”), by the IPv4 Guarantor in favor of the IPv4 Trustee, pursuant to which the IPv4 Guarantor has granted a security interest in the equity interests of the IPv4 Issuer as collateral security for its obligations under the Guaranty. Except as described below, neither we nor any of our subsidiaries, other than the IPv4 Issuer and the IPv4 Guarantor, will guarantee or in any way be liable for the obligations of the IPv4 Issuer under the IPv4 Indenture or the IPv4 Notes.

The IPv4 Notes are subject to a series of covenants and restrictions customary for transactions of this type. These covenants and restrictions include (i) that the IPv4 Issuer maintains a liquidity reserve account to be used to make required payments in respect of the IPv4 Notes such amount considered restricted cash, (ii) provisions relating to optional and mandatory prepayments, including specified make - whole payments in the case of certain optional prepayments of the IPv4 Notes prior to the monthly payment date in May of 2028, (iii) certain indemnification payments in the event, among other things, that the transfers of the assets pledged as collateral for the IPv4 Notes are in stated ways defective or ineffective and (iv) covenants relating to recordkeeping, access to information and similar matters. As provided in the IPv4 Base Indenture, the IPv4 Notes are also subject to rapid amortization in the event of a failure to maintain a stated debt service coverage ratio as defined in the IPv4 Indenture. A rapid amortization may be cured if the debt service coverage ratio exceeds a certain threshold for a certain period of time, upon which cure, regular amortization, if any, will resume. In addition, if certain utilization thresholds are not met (i.e., the proportion of IP addresses that are leased to the total number of IP addresses owned by the IPv4 Issuer falls below certain thresholds), the IPv4 Issuer will be required to apply collections to the repayment of the IPv4 Notes, and in certain circumstances, the noteholders will have the ability to direct a sale of the IP Address Assets, in whole or in part, pursuant to the terms set forth in the IPv4 Indenture. The IPv4 Notes are also subject to certain customary events of default, including events relating to non - payment of required interest, principal or other amounts due on or with respect to the IPv4 Notes, failure to comply with covenants within certain time frames, certain bankruptcy events, breaches of specified representations and warranties, failure of security interests to be effective and certain judgments.

Limitations Under the Indentures

The indentures governing the 2026 Notes, the 2027 Notes and the 2027 Mirror Notes (the “Indentures”), among other things, limit the ability of Group and its restricted subsidiaries to incur indebtedness; to pay dividends or make other distributions; to make certain investments and other restricted payments; to create liens; to consolidate, merge, sell or otherwise dispose of all or substantially all of its assets; to incur restrictions on the ability of a subsidiary to pay dividends or make other payments; and to enter into certain transactions with its affiliates. There are certain exceptions to the limitations on the ability to incur indebtedness under the Indentures, including IRU agreements incurred in the normal course of business and any additional indebtedness if Group’s consolidated leverage ratio, as defined in the Indentures, is less than 6.0 to 1.0 or Group’s fixed charge coverage ratio, as defined in the Indentures, is 2.0 to 1.0 or greater. Group and its subsidiaries can also incur unlimited liens (which can be used, together with capacity under the debt covenant, to incur additional secured indebtedness) if Group’s consolidated secured leverage ratio, as defined in the Indentures, is less than 4.0 to 1.0. Under the Indentures, Group and its restricted subsidiaries can pay dividends, make other distributions, make certain investments and make other restricted payments under certain circumstances, including if, after giving pro forma effect to such restricted payment, Group could still incur $1 of “Ratio Debt,”, as defined (i.e., either its consolidated leverage ratio is less than 6.0 to 1.0 or its fixed charge coverage ratio is 2.0 to 1.0 or greater). As of December 31, 2024, Group’s consolidated leverage ratio was below 6.0, Group’s consolidated secured leverage ratio was below 4.0 and Group’s fixed charge coverage ratio was above 2.0. As of December 31, 2024, a total of $303.6 million was unrestricted and permitted for restricted payments, including dividends and stock purchases.

Summarized Financial Information of Holdings

Neither Holdings nor any of its subsidiaries that is not also a subsidiary of Group is a “Restricted Subsidiary” as defined under the Indentures. Holdings is a guarantor under these notes, but none of its subsidiaries that is not also a subsidiary of Group is a guarantor under these notes. Under the Indentures, we are required to disclose certain reasonably related information of Holdings and its subsidiaries that is not attributable to Group and its subsidiaries, relating to Holdings’ assets, liabilities and operating results (“Holdings Financial Information”). The Holdings Financial Information as of and for the three months and year ended December 31, 2024 is detailed below (in thousands):

Common Stock Buyback Program

Our Board of Directors has approved purchases of our common stock under a buyback program (the “Buyback Program”) through December 31, 2025. During the year ended December 31, 2024, we purchased 153,322 shares of our common stock for $8.0 million. There were no purchases of our common stock during the years ended December 31, 2023 and December 31, 2022. As of December 31, 2024, there was a total of $22.4 million available under the Buyback Program.

Dividends on Common Stock

Dividends are recorded as a reduction to retained earnings. Dividends on unvested restricted shares of common stock are paid as the awards vest. Our initial quarterly dividend payment was made in the third quarter of 2012. On February 26, 2025, our Board of Directors approved the payment of our quarterly dividend of $1.005 per common share. The dividend for the first quarter of 2025 will be paid to holders of record on March 13, 2025. This estimated $47.8 million dividend payment is expected to be made on March 28, 2025. The payment of any future dividends and any other returns of capital, including stock buybacks, will be at the discretion of our Board of Directors and may be reduced, eliminated or increased and will be dependent upon our financial position, results of operations, available cash, cash flow, capital requirements, limitations under our debt indentures and other factors deemed relevant by our Board of Directors. We are a Delaware Corporation and under the General Corporation Law of the State of Delaware distributions may be restricted including a restriction that distributions, including stock purchases and dividends, do not result in an impairment of a corporation’s capital, as defined under Delaware Law. The Indentures limit our ability to return cash to our stockholders. See Note 4 “Long-term Debt” to our consolidated financial statements for additional discussion of limitations on distributions.

Future Capital Requirements

We believe that our cash on hand and cash generated from our operating activities and cash from the IP Transit Services Agreement will be adequate to meet our working capital, capital expenditure, debt service, dividend payments and other cash requirements for the next 12 months and beyond the next 12 months if we execute our business plan.

Any future acquisitions or other significant unplanned costs or cash requirements in excess of amounts we currently hold may require that we raise additional funds through the issuance of debt or equity. In addition, our 2026 Notes will mature in May 2026. At that time we will need to repay our 2026 Notes which may require us to issue additional indebtedness. We cannot assure you that such financing will be available on terms acceptable to us or our stockholders, or at all. Insufficient funds may require us to delay or scale back the number of buildings and markets that we add to our network, reduce our planned increase in our sales and marketing efforts, reduce our planned dividend payments, or require us to otherwise alter our business plan or take other actions that could have a material adverse effect on our business, results of operations and financial condition. If issuing equity securities raises additional funds, substantial dilution to existing stockholders may result.

We may need to, or elect to, refinance all or a portion of our indebtedness at or before maturity and we cannot provide assurances that we will be able to refinance any such indebtedness on commercially reasonable terms or at all. In addition, we may elect to secure additional capital in the future, at acceptable terms, to improve our liquidity or fund acquisitions or for general corporate purposes. In addition, in an effort to reduce future cash interest payments as well as future amounts due at maturity or to extend debt maturities, we may, from time to time, issue new debt, enter into debt for debt, or cash transactions to purchase our outstanding debt securities in the open market or through privately negotiated transactions. We will evaluate any such transactions in light of the existing market conditions. The amounts involved in any such transaction, individually or in the aggregate, may be material.

Off-Balance Sheet Arrangements

We do not have relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these relationships.

Income Taxes

Section 382 of the Internal Revenue Code in the United States limits the utilization of net operating losses when ownership changes, as defined by that section, occur. We have performed an analysis of our Section 382 ownership changes and have determined that the utilization of certain of our net operating loss carryforwards in the United States is limited.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

The accounting policies we believe to be most critical to understanding our financial results and condition or that require complex, significant and subjective management judgments are discussed below.

Acquisition accounting

In connection with our acquisition of the Sprint Business we made the following significant changes to our critical accounting policies and significant estimates. For the fair values of the assets acquired and liabilities assumed, we used the cost, income and market approaches, including market participant assumptions.

​

Page 48 of 96

In connection with the Transaction, the identifiable assets acquired and liabilities assumed were recorded at their fair values as of the acquisition date. Assigning fair market values to the assets acquired and liabilities assumed at the date of an acquisition requires the use of significant judgment regarding estimates and assumptions. We acquired property and equipment comprised of the legacy Sprint network and consists of optical fiber, related equipment, and owned real estate. Management valued these assets using factors that represent an orderly liquidation value, to approximate the highest and best use of assets acquired in a distressed business.

The valuation of the optical fiber requires the estimation of the total replacement cost per mile of fiber and a factor to reflect the orderly liquidation value. There is not active market data for these assumptions and these assumptions are inherently subjective. Market participants could have differing views on these assumptions, which could result in a materially different fair value of the optical fiber.

On the Closing Date, we entered into the IP Transit Services Agreement. We evaluated what elements were part of the business combination and the consideration exchanged to complete the Transaction. We concluded that the payments to be made represent consideration received from T-Mobile to complete the acquisition of a distressed business. We concluded that T-Mobile did not represent a customer, the stated contract price did not represent consideration for services to be delivered, and the transaction did not satisfy the definition of revenue. We also considered whether the IP Transit Services Agreement would be considered separable from the business combination. We concluded that the cash consideration was not separately identifiable from the business combination and was therefore not meant to be in exchange for a distinct good or service. As a result, the IP Transit Services Agreement was recorded in connection with the Transaction at its discounted present value resulting in a discount. The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, among other market factors. The determination of the discount rate and the conclusions reached related to the IP Transit Services Agreement required significant judgment.

The Purchase Agreement includes an estimated payment from Seller to Buyer related to short-term lease obligations. This amount was recorded at its present value resulting in a discount. The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, among other market factors. The determination of the discount rate requires some judgment.

In connection with the Transaction, we recorded an intangible asset totaling $458.0 million for acquired IPv4 addresses. This asset was recorded once management determined both the quantity of IPv4 addresses for which title was transferred and the valuation approach. Because of the novel nature of this asset and that the Transaction has resulted in a material bargain purchase gain, management recorded the asset after appropriate consideration of the valuation approach, in the context of a distressed business. The fair value measurement of the IPv4 addresses was based on recent auction prices and a factor to incorporate the uncertainty for how the market for IPv4 addresses will function in the future. We believe that these IPv4 addresses have an indefinite useful life and are not being amortized. We evaluate the IPv4 intangible asset for impairment on the first day of the fourth quarter, or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable. In performing our impairment assessment, we first evaluated qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. The factors we evaluated include market data for sales and leases of IPv4 addresses and cash flows associated with the asset. Upon consideration of these factors we determined that it was not more-likely-than-not that the asset was impaired, and that a quantitative impairment assessment was not required.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks. These risks, which include interest rate risk and foreign currency exchange risk, arise in the normal course of business rather than from trading activities.

Interest Rate Risk

Interest Expense and Restricted Cash

Our cash flow exposure due to changes in interest rates related to our IPv4 Notes, 2027 Mirror Notes and 2027 Notes is limited as these notes have fixed interest rates. Beginning in August 2021, we used a swap agreement to manage our interest rate risk on our 2026 Notes. Our Swap Agreement has the economic effect of modifying our fixed-interest rate obligation associated with our 2026 Notes to a variable interest rate obligation based on SOFR. The Swap Agreement is recorded at its fair value at each reporting period and we incur gains and losses due to changes in market interest rates. The values that we report for the Swap Agreement as of each reporting date are recognized as an additional non-cash interest expense or a reduction to interest expense with the corresponding amount included in liabilities or assets, respectively, in our consolidated balance sheets. By entering into this Swap Agreement, we have assumed the risk associated with variable interest rates based upon SOFR related to our 2026 Notes. We have not entered into hedge agreements related to our IPv4 Notes, 2027 Mirror Notes or 2027 Notes, and we do not use derivative financial instruments for trading purposes. We have a $23.4 million interest-bearing deposit with the counterparty to our Swap Agreement. If the fair value of the Swap Agreement exceeds a net liability of $23.4 million, we will be required to deposit additional funds with the counterparty equal to the net liability that is in excess of the deposit. As of December 31, 2024, the fair value of the Swap Agreement was a liability of $22.3 million, and as a result, $22.3 million of the deposit was restricted and $1.1 million was unrestricted. A 1.0% change in interest rates as of December 31, 2024 would impact the change in the valuation of our Swap Agreement by approximately $6.2 million.

Interest Income

Our interest income is sensitive to changes in the general level of interest rates. However, based upon the nature and current level of our investments, which consist of cash, cash equivalents and restricted cash, we believe that there is no material interest rate exposure related to our investments.

Foreign Currency Exchange Risk

Our operations outside of the United States expose us to potentially unfavorable adverse movements in foreign currency rate changes. We have not entered into forward exchange contracts related to our foreign currency exposure. While we record financial results and assets and liabilities from our international operations in the functional currency, which is generally the local currency, these results are reflected in our consolidated financial statements in US dollars. Therefore, our reported results are exposed to fluctuations in the exchange rates between the US dollar and the local currencies, in particular the Euro and the Canadian dollar. In addition, we may fund certain cash flow requirements of our international operations in US dollars. Accordingly, in the event that the local currencies strengthen versus the US dollar to a greater extent than planned, the revenues, expenses and cash flow requirements associated with our international operations may be significantly higher in US-dollar terms than planned. During the year ended December 31, 2024, our foreign activities accounted for 17.4% of our consolidated revenue. A 1.0% change in foreign exchange rates would impact our consolidated annual revenue by approximately $1.4 million. Changes in foreign currency rates could adversely and materially affect our operating results and cash flow.
