PART I

Item 1. Business

Business

The Company

Trinseo S.A. (NYSE: TSE) is a public limited liability company (société anonyme) formed in 2010 and existing under the laws of Luxembourg. Prior to our formation, our business was wholly owned by The Dow Chemical Company, which, together with its affiliates, we refer to as “Dow,” and we refer to our predecessor business as “the Styron business.” In 2010, investment funds advised or managed by affiliates of Bain Capital Partners, LP (“Bain Capital”) acquired the Styron business and Dow Europe Holding B.V. (the “Acquisition”). During 2016, Bain Capital divested its entire ownership in the Company in a series of secondary offerings to the market.

We are a leading global materials company and manufacturer of plastics, latex binders and synthetic rubber, including various advanced specialty products and sustainable solutions. We have leading market positions in many of the markets in which we compete. Our products are incorporated into a wide range of our customers’ products throughout the world, including products for automotive applications, tires, carpet and artificial turf backing, coated paper, specialty paper and packaging board, food packaging, appliances, medical devices, consumer electronics and construction applications, among others. We have long-standing relationships with a diverse base of global customers, many of whom are leaders in their markets and rely on us for formulation, technological differentiation, and compounding expertise to find sustainable solutions for their businesses. Many of our products represent only a small portion of a finished product’s manufacturing costs, but provide critical functionality to the finished product and are often specifically developed to customer specifications. Therefore, we seek to regularly develop new and improved products and processes, supported by our intellectual property portfolio, designed to enhance our customers’ product offerings. We believe these product traits result in substantial customer loyalty.

We have significant manufacturing and production operations around the world, which allow us to serve our global customer base. As of December 31, 2020, our production facilities included 32 manufacturing plants (which included a total of 75 production units) at 24 sites across 12 countries, including the Company’s joint venture. Additionally, as of December 31, 2020, we operated 9 research and development (“R&D”) facilities globally, including technology and innovation development centers, which we believe are critical to our global presence and innovation capabilities. Our significant global operations also provide diversity in the end markets for our products.

Our Strategy

We believe that there are significant opportunities to improve our business and enhance our position as a leading global materials company and advanced specialty and sustainable solutions provider. The Company’s strategy is to grow margins and reduce earnings volatility through both organic investment and the pursuit of strategic acquisitions and joint ventures, targeting differentiated technologies focused on providing solutions that meet the evolving needs of our customers. The strategic acquisitions and investments that we pursue will have attractive risk-adjusted returns in markets and geographies that we believe have the best opportunity for growth, while also achieving cost efficiencies across our businesses. In conjunction with our pursuit of targeted growth opportunities, our strategy may also include targeted divestures of underperforming businesses or those less suitable to our portfolio. The Company’s organic growth will be developed through strategic capital investments to extend our leadership position in select market segments and by innovation that provides technological differentiation to our customers who seek our technological and development capabilities to create specialty grades, new and sustainable products, and technologically-differentiated formulations. Supporting this strategy is the Company’s Business Excellence program, first implemented in 2019, which is focused on business process optimization and increasing our operational efficiency and effectiveness.

In 2020, we continued to focus our efforts and investments in product offerings serving the following applications, which are less cyclical and offer significantly higher growth and margin potential: coatings, adhesives, sealants, and elastomers (“CASE”) applications within the Latex Binders segment and engineered materials (“Engineered Materials”) applications, including consumer electronics, medical, and thermoplastic elastomers (“TPEs”) applications. In December 2020, we announced the proposed acquisition of the polymethyl methacrylates (“PMMA”) and activated methyl methacrylates (“MMA”) businesses (together, referred to herein as the “Arkema business”) from Arkema, S.A. (“Arkema”), which we expect to further increase our margin potential and decrease earnings cyclicality. PMMA is a transparent and rigid plastic with a wide range of end uses and is an attractive adjacent chemistry which complements Trinseo’s existing offerings across several end markets including automotive, building & construction, medical and consumer electronics.

In order to support the Company’s growth strategy, we remain committed to maintaining a strong financial position with appropriate financial flexibility and liquidity. The Company employs a disciplined approach to capital allocation and deployment of cash that strives to balance the growth of our business, funding for targeted acquisitions, and continued cash generation, while providing attractive returns to our shareholders. For 2020, this included distributing a quarterly dividend to shareholders of $0.40 per share, and using $25.0 million in cash to repurchase approximately 0.8 million ordinary shares, about 2% of our ordinary shares outstanding at the beginning of the year. In conjunction with our announcement of the proposed acquisition of the Arkema business, we announced the implementation of a dividend reduction and suspension of our share repurchase program, to preserve cash for the transaction and reduce the need for additional indebtedness.

The priorities for uses of available cash include completion of the proposed acquisition of the Arkema business, the servicing of our debt, the continued return of capital to our shareholders via quarterly dividends, the funding of targeted growth initiatives, and the repurchase of our ordinary shares, when deemed appropriate. Management believes that strong cash flow generation, continued profitability, and spending discipline are critical to providing the Company with the ongoing flexibility to pursue our business strategy.

For more information regarding our strategic highlights see Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – 2020 Highlights.

Business Segments

Effective October 1, 2020, we realigned our reporting segments to reflect the new model under which the business will be managed and results will be reviewed by the chief executive officer, who is the Company’s chief operating decision maker. Following this change, the Company is reporting operating results for seven segments, five of which remain unchanged from the Company’s previous segmentation: Latex Binders, Synthetic Rubber, Feedstocks, Polystyrene, and Americas Styrenics. The Company’s former Performance Plastics segment, which included a variety of compounds and blends as well as the results of the acrylonitrile-butadiene-styrene (“ABS”), styrene-acrylonitrile (“SAN”), TPE, and polycarbonate (“PC”) businesses, was reorganized into two standalone reporting segments, Engineered Materials and Base Plastics. The new Engineered Materials segment includes the Company’s compounds and blends products sold into higher growth and value applications, such as consumer electronics and medical, as well as

6

Table of Contents

the Company’s TPE products which are sold into a variety of applications including footwear and automotive. The new Base Plastics segment contains the results of the remaining businesses, including the ABS, SAN, and PC businesses, as well as compounds and blends for automotive and other applications. This segmentation change will provide enhanced clarity to investors by placing the results of the Company’s products sold into engineered materials applications into a single reporting segment, which aligns with the Company’s strategy to focus our efforts and investments in these applications, as they tend to be less cyclical and offer significantly higher growth and margin potential.

Refer to Note 19 in the consolidated financial statements for information regarding sales, Adjusted EBITDA, the performance metric used by management to evaluate our segments’ performance, and capital expenditures by segment, as well as sales and long-lived assets by geographic area.

Latex Binders Segment

Overview

We are a global leader in styrene-butadiene latex (“SB latex”), holding a strong market position across the geographies and applications in which we compete, including the #2 position in SB latex capacity in Europe and the #1 position in capacity in North America, based on third party data. In 2020, approximately 44% of our Latex Binders segment’s sales were generated in Europe, 29% were generated in the United States, and the majority of the remaining net sales were generated in Asia. Additionally, this segment includes the results of our styrene-acrylate latex (“SA latex”) production facilities and related infrastructure in Rheinmünster, Germany.

Products and End Uses

We hold the #1 position for supplying latex binders for the coated paper and board market globally. SB latex is widely used as a binder for mineral pigments as it allows high coating speeds, improved smoothness, higher gloss level, opacity and water resistance that is valued in the product’s end use in advertising, magazines, and packaging board coatings.

We are also the #1 supplier of latex binders to the carpet, carpet tile and artificial turf market and offer a diverse range of products for use in residential and commercial applications. We produce SB latex, SA latex, vinylidene chloride, and butadiene-methacrylate latex products for the commercial and niche carpet markets. SB latex is also used in flooring as an adhesive for carpet and artificial turf fibers. We continue to implement new chemistries for paper coating and carpet backing applications.

We also offer a broad range of performance latex binders products, including SB latex, SA latex, and vinylidene chloride latex for CASE applications. Net sales to CASE applications made up approximately 14% of total Latex Binders net sales in 2020, with margins of more than two times the average of products serving all applications within the segment.

Competition and Customers

Our principal competitors in our Latex Binders segment include BASF Group and Synthomer plc. In this segment we compete primarily based on our ability to offer differentiated and reliable products, the quality of our customer service, and the length and depth of our relationships. This industry has seen capacity reduction and consolidation which we believe could positively impact our competitive standing.

We believe our Latex Binders segment is able to differentiate itself by offering customers value-added formulations and product development expertise. Our R&D team and Technical Services and Development (“TS&D”) team are able to use our pilot coating facility, paper fabrication and testing labs, carpet technology centers located near carpet producers, and product development and process research centers to assist customers in designing new products and enhancing their manufacturing processes. Many of our major customers rely on our dedicated R&D and TS&D teams to complement their limited in-house resources for formulation and reformulation tests and trials. We believe that this capability allows us to capture new business, strengthen our existing customer relationships and broaden our technological expertise.

Additionally, our global manufacturing capabilities are key in serving customers cost-effectively, as latex binders are costly to ship over long distances due to their high water content. We believe that our global network of service and

7

Table of Contents

manufacturing facilities is highly valued by our customers. We seek to capture the value of our R&D and TS&D services and manufacturing capabilities through our pricing strategy. In 2020, we estimate that more than half of net sales in this segment related to contracts that include raw material pass-through clauses.

Seasonality

Reporting periods impacted by the winter season and unfavorable weather conditions that typically affect the construction and building materials end markets may result in seasonally lower performance, particularly in the CASE applications of our Latex Binders segment.

Synthetic Rubber Segment

Overview

We are a significant producer of styrene-butadiene rubber products and we have a leading European market position, providing approximately 44% of Western Europe’s SSBR capacity available for sale. While substantially all of our net sales were generated in Europe in 2020, approximately 26% of these net sales were exported to Asia, 12% to North America, and 5% to Latin America.

In December 2020, we announced our intent to explore the potential divestiture of our Synthetic Rubber business. We believe that our Synthetic Rubber business remains a valuable asset with potential for growth in the global tire market.

Products and End Uses

Our Synthetic Rubber segment produces synthetic rubber products used in high-performance tires and technical rubber products, such as conveyor belts, hoses, seals and gaskets. We participate significantly in the European synthetic rubber industry, where tire producers focus on high-performance and ultra high-performance tires and rely heavily on their rubber suppliers. We have a broad synthetic rubber technology and product portfolio, focusing on specialty products, such as solution styrene-butadiene rubber (“SSBR”), while also producing core products, such as emulsion styrene-butadiene rubber (“ESBR”). Our synthetic rubber products are extensively used in tires, with approximately 88% of our net sales from this segment in 2020 attributable to the tire market. We have strong relationships with many of the top global tire manufacturers and believe we have remained a supplier of choice as a result of our broad rubber portfolio and ability to offer technologically-differentiated product and product customization capabilities. Other applications for our synthetic rubber products include technical rubber goods.

SSBR. We sell SSBR products for high-performance and ultra high-performance tire applications. We produce both clear and oil extended SSBR through batch polymerization in our four SSBR production lines. We believe these processes provide leading and technologically-differentiated solutions to tire manufacturers.

During the last several years, we have been working closely with major tire producers around the world to develop multiple new SSBR grades, addressing key marketplace needs for improved tire fuel economy, grip, and abrasion characteristics, which we believe will lead to significant demand growth for our rubber products in Europe and around the world. Sales of advanced SSBR grades as a percentage of our total Synthetic Rubber segment have continually increased since 2013, and we expect our synthetic rubber product mix to continue to shift to more advanced SSBR grades in order to meet this shift in product demand. In 2020, SSBR represented approximately 64% of total segment net sales. Our SSBR margins are typically around three times those of our ESBR commodity grade synthetic rubber.

Performance tires represent an especially attractive market to rubber producers because they provide substantial value to end customers. In fact, the market for performance tires is expected to grow at an average annual rate of approximately 8% from 2020 through 2025. Tire manufacturers are expected to continually seek improvements in advanced rubber, which optimizes the combination of fuel economy and wet grip in order to meet European Union (“EU”) regulations which set minimum requirements and are being phased in through 2021. Other jurisdictions have adopted or are considering similar legislation and are also beginning to adopt the tire labeling requirements that have become mandatory in Europe. We believe our growth prospects are enhanced by increasing demand for high-performance tires, which, as a result of regulatory reforms aimed at improving fuel efficiency and reducing carbon dioxide emissions in the EU, Japan, and Korea, are now more commonly used by automakers as original equipment manufacturer specified tires in their vehicles.

Table of Contents

ESBR. Our ESBR products are used in a wide range of applications within tire and technical rubber goods segments. Our ESBR product portfolio offers tire producers a comprehensive suite of synthetic rubber capabilities. For example, ESBR provides enhanced wet grip to tire treads and strength to the inner liner of tires, allowing the tires to be more easily processed. In 2020, ESBR represented approximately 30% of total segment net sales.

Ni-PBR and Nd-PBR. In May 2020, the Company made the determination to mothball both its nickel polybutadiene rubber (“Ni-PBR”) and neodymium polybutadiene rubber (“Nd-PBR”) production assets at our Schkopau, Germany location, which was completed in December 2020. This decision was made in furtherance of the Company’s strategy to focus efforts and increase investments in certain products that are less cyclical and offer higher growth and margin potential. Our Ni-PBR products have been sold for use in standard tires, performance tires, technical goods, and footwear. Nd-PBR is a key material in the latest generation of performance tires and has also been sold for use in industrial rubber goods and polymer modification. In 2020, Ni-PBR and Nd-PBR represented in aggregate approximately 6% of total segment net sales.

Competition and Customers

Our principal competitors in our Synthetic Rubber segment include Asahi Kasei Corporation, JSR Corporation, Sumitomo Zeon Elastomers, ARLANXEO, Kumho Petrochemical Co., Ltd., Versalis S.p.A, LG Chem, and Synthos S.A. In our Synthetic Rubber segment, we compete primarily based on our ability to offer differentiated and reliable products, the quality of our customer service and the length and depth of our relationships. We maintain deep and long-standing relationships with a large number of multinational customers, including many of the top global tire manufacturers, as well as fast growing Asian tire manufacturers. Our relationships with our top customers, including with our predecessor business operated by Dow prior to the Acquisition (as defined in Note 1 in the consolidated financial statements), range from 10 to more than 20 years. In 2020, our top three customers in this segment accounted for 54% of segment net sales. The loss of one or more of these customers could have a material adverse effect on the performance of the Synthetic Rubber segment.

We believe that we are a supplier of choice to our customers, given our broad rubber portfolio, including technologically-differentiated grades, and our product customization capabilities. Our R&D and TS&D teams use our broad rubber portfolio to develop differentiated specialty products for customers. Once implemented with a customer, these newly-developed specialty products cannot be easily replaced with a competitor’s product. As a result, we believe customers are likely to buy from us throughout the life cycle of specific tire models to avoid high switching costs and prevent repetition of the expensive development process.

Functionalized SSBR, which is a specialized, higher margin grade of SSBR used in high-performance and ultra high-performance tires, provides superior performance on grip, durability and rolling resistance. Trinseo is one of the largest suppliers of functionalized SSBR in Europe with a leading position in functionalization technology. Functionalized SSBR is expected to grow at an average annual rate of approximately 10% from 2020 through 2025, which is nearly twice the expected rate of non-functionalized SSBR.

Since 2018 the Company has worked to bolster its position in the SSBR market by increasing SSBR capacity and utilizing its SSBR pilot plant to allow for an expedited product development process from lab sample to commercialization, by delivering sufficient quantities of new formulations without the need to interrupt production in our industrial lines.

While we export our rubber products worldwide, our production facilities are solely in Europe. Therefore, we may face competitive challenges with customers who would prefer local manufacturers. However our technology leadership providing customers advancement in their products prevails, supporting the traction for global sales.

While the prices of raw materials used in the production of products in this segment can fluctuate, approximately three quarters of net sales in 2020 in this segment were related to contracts that included raw material pass-through clauses.

We are also focused on supplying customers with sustainable solutions. Among other initiatives, in October 2020 we announced an agreement with Tyre Recycling Solutions on a commercial collaboration and equity investment. This agreement is aimed towards collaboration on research and development to help global tire manufacturers develop more sustainable tire formulations which are expected to reduce the manufacturing environmental footprint and create a sustainable outlet for end-of-life tires.

Seasonality

Our Synthetic Rubber segment experiences some seasonality with its highest period of demand typically occurring during the first quarter of the year as inventories are built ahead of the summer season. The lowest period of demand normally occurs during the third quarter of the year due to the summer holidays.

Engineered Materials Segment

Overview

Our Engineered Materials segment consists of rigid thermoplastic compounds and blends products sold into high growth and high value applications in markets such as consumer electronics and medical, as well as soft TPE products which are sold into markets such as footwear and automotive. In 2020, approximately 28% of total Engineered Materials net sales were generated in Europe, approximately 17% were generated in the United States, and approximately 53% were generated in Asia.

Products and End Uses

Products in the Engineered Materials segment are split into rigid compounds and soft plastic compounds. Rigid compounds include PC compounds, ABS compounds, and PC blends, mostly PC/ABS, and support primarily the consumer electronics and medical markets for equipment housing applications. TPE soft plastic compounds are focused on supporting footwear shoe sole applications, personal care, consumer electronics, and automotive high-end applications such as overmolds, sealings, tubing, and films.

The benefit of Trinseo’s portfolio in our Engineered Materials segment is the high level of customization for high-end applications at selected premium brand owners, and clear orientation to sustainable solutions. Our current portfolio includes sustainable solutions, such as high content post-consumer recycled (“PCR”) polycarbonate and bio-based raw materials. We are developing further solutions to expand our sustainable offering using PCR ABS and PCR TPE. Sustainable products represented 14% of Engineered Materials segment volume in 2020 and are a core growth area.

We manufacture our rigid products mainly under the EMERGE brand for consumer electronics, and under the CALIBRE brand for medical markets. Supported by current macro trends, specifically as it relates to safety and health, remote servicing and working, and sustainability, we believe that we have additional growth opportunities in existing consumer electronics applications, including tablets, notebooks, smart phones and other handheld devices, as well as new voice control systems, home entertainment and delivery equipment. We also foresee growth in medical wearables, home equipment, and drug delivery devices. In serving these markets, we leverage our polymer and compound technologies to meet increasingly stringent performance requirements along with our customers’ aesthetic and color-matching requirements, which are crucial characteristics for the products involved.

We manufacture our TPE soft plastic compounds principally under the trade names MEGOL, APILON, APIGO, and APINAT. Growth in footwear is supported by bio solutions in both luxury and sport premium markets, while automotive growth is orientated to hygienic interiors and both robust and smart surfaces.

On December 2, 2020, we commenced operations at our TPE pilot facility in Hsinchu, Taiwan, which will serve as a complement to our existing primary TPE development center in Mussolente, Italy. The pilot facility will enable faster innovation cycles in close collaboration with Asia Pacific customers for sustainably advantaged materials in targeted markets including consumer electronics, medical, footwear, and automotive.

Competition and Customers

We compete in the Engineered Materials segment primarily based on our ability to offer differentiated and reliable products, high quality customer service, and deep relationships with prioritized customers. We believe that growth in this segment will stem from the continued high demand for engineered and sustainable product solutions serving the consumer electronics, medical and TPE application markets. We believe our track record of innovation and our focus on differentiated products enhances our growth prospects in this segment. We also believe that our global organization and

10

Table of Contents

facilities are a competitive advantage that allows us to provide customers with consistent grades across markets and positions us to strategically serve emerging markets.

Seasonality

Due to the steady demand state of a portfolio of applications in many markets, such as consumer electronics, medical devices, and footwear, the Engineered Materials segment does not experience significant seasonality.

Base Plastics Segment

Overview

Our Base Plastics segment consists of a variety of compounds and blends, the majority of which are for automotive applications. The segment also includes our ABS, SAN, and PC businesses. In 2020, approximately 56% of net sales from our Base Plastics segment were generated in Europe, 22% were generated in the United States, and 15% were generated in Asia.

Products and End Uses

Copolymers. Our copolymers products consist of ABS and SAN. In 2020, copolymers represented approximately 55% of total segment net sales.

We are a leading producer of ABS in Europe and are one of the few global producers, with a presence in both North America and China. We produce mass ABS (“mABS”), a variation of ABS that has lower conversion and capital costs compared to the more common emulsion ABS (“eABS”) process, marketed under our MAGNUM brand. mABS has similar properties to eABS but has greater colorability, thermal stability and lower gloss. mABS products can be manufactured to stricter specifications because they are produced in a continuous process as opposed to the batch process used in eABS. mABS also has environmental benefits such as waste reduction and higher yields. In addition to our own mABS production capacity, we have licensed our proprietary mABS technology to other producers.

Primary end uses for our ABS products include automotive and construction sheet applications. We maintain a significant share of ABS sales into these markets, which we believe is due to the differentiating attributes of our mABS products, our reputation as a knowledgeable and reliable supplier, our broad product mix, and our customer collaboration, including design capabilities.

SAN is composed of styrene and acrylonitrile, which together provide clarity, stiffness, an enhanced ability to be processed, mechanical strength, barrier properties, chemical resistance and heat resistance. SAN is used mainly in appliances, consumer goods and construction sheets, due to its low cost, clarity and chemical resistance properties.

PC. Our PC products are manufactured in Stade, Germany and are sold into various markets as well as consumed internally for our compounding products. In 2020, PC represented approximately 15% of total segment net sales.

PC has high levels of clarity, impact resistance and temperature resistance. PC can be used in its neat form (prior to any compounding or blending) for markets such as construction sheet, optical media, medical and LED lighting. Additionally, PC can be compounded or blended with other polymers, such as ABS, which imparts specific performance attributes tailored to the product’s end use.

Our products for glazing and construction sheets are marketed under the CALIBRE brand name and offer customers a combination of clarity, heat resistance and impact performance. Glazing and construction sheet represents our largest PC application and one of the key end markets is the construction industry.

Compounding. Our compounding products consist of PC/ABS compounds, PC blends, and PC and polypropylene blends. In 2020, compounding products represented approximately 30% of total segment net sales.

We have a significant position in PC/ABS blends, which combine the heat resistance and impact strength of PC with the easy-to-process qualities and resilience of ABS. We have also developed compounds containing PCR content in their products. We believe our ability to offer technologically-differentiated products to meet customer needs sets us apart from our competitors, and with our history as a leading innovator in compounds and blends, we have established ourselves as a leading supplier of PC-based products.

11

Table of Contents

For the automotive industry, we manufacture PC/ABS blends under the PULSE brand, and we innovate collaboratively with our customers to develop performance solutions to meet industry needs, such as reducing the weight of vehicles or providing products using recycled content. As a result, we are a key supplier of these products to leading automotive companies in North America and Europe, who tend to specify these products on a per car platform basis, making it difficult to be displaced as a supplier once selected and providing us with relatively stable and predictable cash flows for several years during the production lifecycle. We are also accelerating our development of similar supply capabilities in additional geographies, like China.

Additionally, we believe growth prospects are bolstered by sustainability trends, such as the substitution of lighter-weight plastics for metal in automobiles. Therefore, we believe our history of innovation and our focus on differentiated products enhances our growth prospects in this segment. Our innovation has contributed to long-standing relationships with customers who are recognized leaders in their respective end markets. We also believe our global facilities are a competitive advantage that allows us to provide customers with consistent grades across markets, and positions us to strategically serve emerging markets.

Seasonality

Reporting periods impacted by the winter season and unfavorable weather conditions that typically affect the construction and building materials end markets may result in seasonally lower performance in our Base Plastics segment.

Polystyrene Segment

Overview

We are a leading producer of polystyrene and focus on sales to injection molding and thermoforming customers. In 2020, approximately 58% of net sales from our Polystyrene segment were generated in Europe and 42% of net sales were generated in Asia.

Products and End Uses

Our product offerings include a variety of general purpose polystyrenes (“GPPS”) and high impact polystyrene (“HIPS”), which is polystyrene that has been modified with polybutadiene rubber to increase its impact resistant properties. These products provide customers with performance and aesthetics at a low cost across applications, including appliances, packaging, including food packaging and food service disposables, consumer electronics and building and construction materials.

The STYRON™ brand is one of the longest established brands in the industry and is widely recognized in the global marketplace. We believe our R&D capabilities provide valuable, differentiated solutions for our customers, making us well-positioned to address the sustainability, weight reduction, and safety needs.

Competition and Customers

Our principal competitors in our Polystyrene segment are INEOS Styrolution, Versalis S.p.A., Total S.p.A., Sinopec Corp., Formosa Chemicals & Fibre Corp., and Chi Mei Corporation. In this segment, we compete primarily based on our ability to offer reliable products as well as the quality of our customer service and the length and depth of our relationships.

Our customer-centric model focuses on understanding customers’ needs and developing tailored relationships that add value beyond the value of the actual product performance. For durable applications, we focus our TS&D, R&D and

Table of Contents

marketing teams on product design engineering initiatives for developing and specifying plastics in the next generation of construction applications and appliances. In non-durable applications, we focus on innovative products that provide clear cost advantages to our customers, serving customers with our cost-advantaged technology and operating excellence. We have leveraged industry-leading product development and technology capabilities in many of our product lines in this segment to develop long-standing customer relationships, including with a number of customers who have purchased from us, including our predecessor business operated by Dow for more than 20 years. We believe that our asset footprint is an advantage, allowing us to provide customers with consistent product grades and positioning us to strategically serve growth economies.

​

Seasonality

Due to the geographic diversity of the Company’s customers and end markets for our polystyrene products across the globe, our Polystyrene segment does not typically experience material levels of seasonality. However, sales volumes may fluctuate from quarter-to-quarter as customers may adjust their purchasing patterns based on their expectations of polystyrene price changes.

Feedstocks Segment

Overview

Trinseo is a large consumer of styrene monomer globally. The primary function of our Feedstocks segment is the production of styrene monomer in Europe in order to provide secure sourcing of this key raw material to our other segments. In fact, the majority of the styrene monomer produced by our Feedstocks segment is consumed by our other segments. However, we do sell a portion of our produced styrene monomer to third parties. Overall, our Feedstocks segment supplied 15% of the European styrene monomer capacity in 2020.

Products and End Uses

Styrene monomer is a basic building block of plastics and a key input to many of the Company’s products. Styrene monomer is a key raw material for the production of polystyrene, expandable polystyrene, SAN resins, SA latex, SB latex, ABS resins, unsaturated polyethylene resins, and styrene-butadiene rubber.

Competition and Customers

Our principal competitors in our Feedstocks segment are: INEOS Styrolution, Versalis S.p.A., Total S.p.A., BASF SE, Saudi Basic Industries Corporation, LyondellBasell, Repsol S.A., and Royal Dutch Shell plc. The majority of styrene monomer produced within the Feedstocks segment is consumed by the Company in our own manufacturing activities.

Global styrene operating rate percentages were in the high 70’s in 2020 and we believe operating rates will remain at similar levels over the next several years. The operating rate could be positively impacted by the potential closure of higher-cost styrene plants. Effective operating rates can, from time to time, be impacted by planned and unplanned outages, leading to periods of elevated margins.

Seasonality

Our Feedstocks segment does not generally experience material levels of seasonality affecting sales volumes; however, there may be seasonal fluctuations in margin as planned supply outages generally occur more often in the spring and fall seasons.

Americas Styrenics Segment

Overview

This segment consists solely of the operations of our 50%-owned joint venture with Chevron Phillips Chemical Company, Americas Styrenics LLC (“Americas Styrenics”), which continues to be a leading producer in North America of both styrene and polystyrene. In 2020, Americas Styrenics was the #1 producer of polystyrene, based on capacity data, and supplied 18% of the styrene monomer capacity in North America. We received a total of $15.0 million in cash dividends from Americas Styrenics during 2020. We estimate that the contribution to our equity earnings from Americas

13

Table of Contents

Styrenics’ polystyrene business was approximately 75% in 2020, 49% in 2019, and 32% in 2018. This translates to a contribution from Americas Styrenics’ polystyrene business to our Adjusted EBITDA of approximately 17% in 2020, 13% in 2019, and 8% in 2018.

Products and End Uses

Styrene monomer is a basic building block of plastics and a key input to many of the Company’s products. Styrene monomer is a key raw material for the production of polystyrene, and in 2020 approximately 55% of the styrene monomer produced by Americas Styrenics was consumed in its own production of polystyrene. The remainder of Americas Styrenics’ product is sold as a key raw material to other manufacturers of polystyrene, expandable polystyrene, SB latex, ABS resins, unsaturated polyethylene resins, and styrene-butadiene rubber.

Americas Styrenics also produces GPPS, high heat, high impact resin, and STYRON A-TECH™ polystyrene products. Major applications for these polystyrene products include appliances, food packaging, food service disposables, consumer electronics, and building and construction materials.

Competition and Customers

Americas Styrenics’ principal competitors are INEOS Styrolution, Total S.p.A., and LyondellBasell. In our Americas Styrenics segment, we compete primarily based on our ability to offer reliable products as well as the quality of our customer service and the length and depth of our relationships.

As a leading styrenics producer in North America, this segment is well-positioned to benefit from consolidation dynamics in the styrene and polystyrene industries within the region. As noted above in the Feedstocks segment section, global styrene operating rate percentages were in the high 70’s in 2020 and we believe they will remain at similar levels over the next several years, with the potential for positive upside if there are closures of higher-cost styrene plants. Effective operating rates can, from time to time, be impacted by planned and unplanned outages, leading to periods of elevated margins.

Seasonality

Reporting periods impacted by the winter season and unfavorable weather conditions that typically affect the construction and building materials end markets may result in seasonally lower performance in our Americas Styrenics segment.

Our Relationship with Dow

Following the Acquisition, we entered into certain long-term agreements with Dow to provide services that would ease our transition into a standalone company. Those agreements included the Amended and Restated MOD5 Computerized Process Control Software, Licenses and Services Agreement, with Rofan Services (“AR MOD5 Agreement”), the Second Amended and Restated Master Outsourcing Services Agreement (“SAR MOSA”), certain site and operating services agreements, and raw material supply agreements.

Under the AR MOD5 Agreement, Dow provides worldwide process control technology, including hardware, software licenses and support services, and related enterprise resource planning services. The AR MOD5 Agreement, as amended, has a term through December 2023, and may be terminated by either party for cause or uncured material breach; by Trinseo if we no longer wish to receive maintenance and support for any licensed software; or by Dow if we use the licensed software for any purposes other than Company business. Dow may terminate the maintenance and support terms at any time if we fail to make payments when due. As of December 31, 2020, we have converted over half of our plants from the MOD5 process control technology and are no longer reliant on Dow for such process control technology at those plants. We expect to convert the remainder of our plants by the end of 2023.

The SAR MOSA provided for ongoing worldwide services from Dow, in areas such as information technology, enterprise resource planning, finance, environmental health and safety, training, customer service, marketing and sales support, supply chain and certain sourcing and transactional procurement services. From 2018 through 2020, the Company worked to insource, and in some cases outsource to other vendors, certain information technology, procurement, supply chain, finance, and enterprise resource planning (“ERP”) services and systems that were being

14

Table of Contents

provided by Dow. By mid-2020, substantially all of the services covered under this agreement were no longer provided by Dow. During 2020, the Company incurred $24.6 million in costs related to our transition of these services away from Dow, of which $6.5 million was capitalized and $18.1 million was recognized as expense. The Company does not expect to incur any further significant costs related to transitioning services away from Dow under the SAR MOSA in 2021.

In addition, we entered into various site services agreements (“SAR SSAs”) with Dow to provide site services to the Company at Dow-owned sites. Conversely, we entered into similar agreements with Dow, where, at Company-owned sites, we provide such services to Dow. These agreements cover general services that are provided at certain facilities co-located with Dow, including utilities, site administration, environmental health and safety, site maintenance and supply chain. These agreements generally have 25-year terms and include options to renew. These agreements may be terminated at any time by agreement of the parties, or, by either party, for cause or under certain circumstances for a material breach. In addition, we may terminate with 12-months’ prior notice to Dow any services identified in any SAR SSA as “terminable.” Highly integrated services, such as electricity and steam, generally cannot be terminated prior to the termination date unless we experience a production unit shut down for which we provide Dow with 15-months’ prior notice, or upon payment of a shutdown fee. Upon expiration or termination, we would be obligated to pay a monthly fee to Dow for a period of 45 to 60 months following the expiration or termination of such SAR SSA. The agreements under which Dow receives services from us may be terminated under the same circumstances and conditions.

In addition, at the date of the Acquisition, we entered into a contract manufacturing agreement pursuant to which we operate and maintain our SAN facility in Midland, Michigan to manufacture products for Dow. This agreement has a 25-year term, with automatic renewals for five-year terms unless one party gives notice at least 18 months prior to the end of the period. We may terminate any operational service under the agreement in the event that we experience a production unit shutdown, with 15-months’ prior notice to Dow. Furthermore, the agreement may be terminated by mutual agreement between the parties, by either party on notice that the other party fails to cure non-performance or if the other party is in material breach of a material obligation under the agreement within certain parameters, or because of either party’s insolvency.

For the years ended December 31, 2020, 2019, and 2018, we incurred a total of $155.4 million, $204.0 million, and $265.1 million, respectively, in expenses under the SAR MOSA, AR MOD5 Agreement, and SAR SSAs (which include utilities), including $139.2 million, $164.2 million, and $210.8 million, respectively, for both the variable and fixed cost components of the site services agreements and $16.2 million, $39.8 million, and $54.3 million, respectively, covering all other agreements.

For the years ended December 31, 2020, 2019, and 2018, purchases and other charges from Dow and its affiliated companies (excluding the SAR MOSA, AR MOD5 Agreement, and SAR SSAs) were approximately $659.5 million, $781.9 million, and $1,145.5 million, respectively. These purchases and other charges primarily relate to the purchase of raw materials for manufacturing of our products, as discussed further below. Additionally, for the years ended December 31, 2020, 2019, and 2018, sales to Dow and its affiliated companies were approximately $98.4 million, $80.0 million, and $248.4 million, respectively. Amounts presented represent transactions with Dow and do not include transactions with DuPont companies, noting the entities separated in 2019.

We continue to procure certain raw materials, utilities, and site services from Dow. We are party to several agreements with Dow for the provision of certain raw materials, products and services and other operational arrangements. Dow provides a large percentage of certain raw materials used in the production of our products, under agreements that are important to our business. The failure of Dow to perform their obligations, or the termination of these agreements, could adversely affect our operations. See Item 1A—Risk Factors.

Sources and Availability of Raw Materials

The prices of our key raw materials are volatile and can fluctuate significantly over time. While the predominant reason for this volatility is the impact of market imbalances in supply and demand from time to time, energy prices may also impact the volatility of some of our raw materials. The table below shows our key raw materials by reporting segment.

We have supply contracts in place to help maintain our supply of raw materials at competitive market prices and seek to implement the most efficient and reliable raw material strategy for each of our segments, including maintaining a balance between contracted and spot purchases of raw materials. We also produce raw materials for use by our businesses, such as styrene monomer.

In 2020, we obtained approximately 29% of our raw materials from Dow (based on aggregate purchase price). In 2020, Dow supplied us with approximately 95% of our benzene requirements and 99% of our ethylene requirements. Dow continues to be our largest supplier for these raw materials as well as a significant supplier of butadiene. In 2020, we executed new supply agreements with Dow for ethylene, benzene, and butadiene, which commence in 2021 and have contractual terms of two to five years, with renewal provisions.

While Dow provides a significant portion of our raw materials pursuant to these supply agreements, we have developed a comprehensive strategy for obtaining additional sources of supply where needed. Other supply sources in Europe include major producers with contract terms of up to five years at competitive market prices. Supply to North America and Asia are exclusively from other major third-party producers via supply contracts.

Through long-term strategic contracts and spot market purchases, we obtained 36% and 24%, respectively, of our styrene supply in 2020. Additionally, our internal production of styrene from purchased ethylene and benzene at our own manufacturing sites provided 40% of our styrene supply in 2020. With this mix of purchased and produced styrene, we seek to optimize our overall costs of securing styrene through efficient logistics, manufacturing economics and market dynamics.

Bisphenol A (“BPA”) is the major raw material associated with PC production. Our supply of this raw material is produced by a subsidiary of Olin Corporation and is provided to us via pipeline. In 2020, we executed a three-year supply agreement with Olin Corporation with a term through December 31, 2022.

Technology

Our R&D and TS&D activities across our segments focus on identifying needs in our customers’ end markets. As part of our customer-centric model, our R&D/TS&D organization interfaces with our sales and marketing teams and directly with customers to determine their product requirements, considering industry and market segment trends. This information is used to select R&D/TS&D projects that are value-enhancing for both our customers and Trinseo.

Our innovation and technology centers support our technological and R&D/TS&D capabilities. In addition, our R&D/TS&D efforts are also supported by certain “mini-plants” operated by our businesses in Stade and Schkopau, Germany. These mini plants are used to make samples of experimental products for testing, which we believe is a critical step in our new product development process. We also operate a plastics research center, which integrates two existing technical support centers and research lab operations in a single location at our Terneuzen, The Netherlands office location. Further, we operate pilot plants to facilitate new production technology, including a new TPE pilot facility in

16

Table of Contents

Hsinchu, Taiwan where we commenced operations in December 2020. The new TPE facility will enable faster innovation cycles in close collaboration with Asia Pacific customers for sustainably advantaged materials in targeted markets including consumer electronics, medical, footwear, and automotive.

R&D and TS&D costs are included in expenses as incurred. Our R&D and TS&D costs were $60.4 million, $54.6 million, and $56.0 million, for the years ended December 31, 2020, 2019, and 2018, respectively.

Sales and Marketing

We have a customer-centric business model that has helped us to develop strong relationships with many customers. Our sales and marketing professionals are primarily located at our facilities or at virtual offices within their respective geographies. We have approximately 162 professionals working in sales and marketing around the world, along with approximately 93 customer service professionals and we sell our products to customers in approximately 80 countries. We primarily market our products through our direct sales force. Typically, our direct sales are made by our employees in the regions closest to the given customer.

Intellectual Property

We evaluate on a case-by-case basis how best to utilize patents, trademarks, copyrights, trade secrets and other intellectual property to protect our products and our critical investments in research and development, manufacturing and marketing. We focus on securing and maintaining patents for certain inventions, while maintaining other inventions as trade secrets, derived from our customer-centric business model, to maximize the value of our product portfolio and manufacturing capabilities. Our policy is to seek appropriate protection for significant product and process developments in the major markets where the relevant products are manufactured or sold. Patents may cover products, processes, intermediate products and product uses. Patents extend for varying periods in accordance with the date of patent application filing and the legal life of patents in the various countries. The protection afforded, which may also vary from country to country, depends upon the type of subject matter covered by the patent and the scope of the claims of the patent.

In most industrial countries, patent protection may be available for new substances and formulations, as well as for unique applications and production processes. However, given the geographical scope of our business and our continued growth strategy, there are regions of the world in which we do business or may do business in the future where intellectual property protection may be limited and difficult to enforce. We maintain strict information security policies and procedures wherever we do business. These information security policies and procedures include data encryption, controls over the disclosure and safekeeping of confidential information, as well as employee awareness training. Moreover, we monitor our competitors’ products and, if circumstances were to dictate that we do so, we would vigorously challenge the actions of others that conflict with our patents, trademarks and other intellectual property rights.

The technologies we utilize in some of our businesses have been in use for many years (e.g., SB latex and ABS) and a number of our patents relating to such technologies have expired or will expire in within the next several years. As patents expire, or are allowed to lapse, the products and processes described and claimed in those patents become generally available for use by the public. We believe that the expiration of any single patent or family of patents that is scheduled to expire in the next three years would not materially adversely affect our business or financial results. We believe that our trade secrets relating to manufacturing and other processes used in connection with products to which expiring patents relate will continue to provide us with a competitive advantage after the expiration of these patents.

We use trademarks as a means of differentiating our products. We protect our trademarks against infringement where we deem appropriate. We have successfully registered the TRINSEO™ trademark in more than 130 countries.

Dow has either transferred to us or granted perpetual, royalty-free licenses to us to use Dow’s intellectual property that was used by Dow to operate the Styron business prior to the Acquisition. This intellectual property includes certain processes, compositions and apparatus used in the manufacture of our products. In addition to our license rights to use Dow’s intellectual property related to the Styron business, we have obtained licenses to use Dow’s intellectual property to the extent necessary to perform our obligations under the contracts transferred to us in the Acquisition and to use such intellectual property (other than patents) for products outside of the Styron business as it was conducted by Dow prior to the Acquisition, subject to certain limitations. While we believe our license rights with respect to Dow’s intellectual property are sufficient to allow us to operate our current business, new growth opportunities in latex binders, and to a

17

Table of Contents

lesser extent plastics, involving new products may fall outside of our license rights with Dow. Therefore, our ability to develop new products may be impacted by intellectual property rights that have not been licensed to us by Dow. We have the right, with Dow’s cooperation, to directly enforce the patents that are exclusively licensed to us by Dow where infringement is primarily within the scope of our business; but nothing obligates Dow to enforce against third parties the intellectual property rights of Dow that are licensed to us on a non-exclusive basis or where the infringement is primarily outside the scope of our business.

Since our formation on June 17, 2010, we have focused our product innovation across our various product lines. The intellectual property that we have created or acquired since the Acquisition is largely in these segments and covers areas such as material formulations, material process technologies and various end-use industrial applications.

Environmental, Health, Safety and Product Stewardship

Obtaining, producing and distributing many of our products involve the use, storage, transportation and disposal of toxic and hazardous materials. We are subject to extensive, evolving and increasingly stringent national and local environmental and safety laws and regulations, which address, among other things:

We monitor compliance with applicable state, national, and international environmental, health and safety requirements and maintain policies and procedures to monitor and control environmental, health and safety risks, which may in some circumstances exceed the requirements imposed by applicable law. We have a strong environmental, health and safety organization with a staff of professionals who are responsible for environmental, health, safety and product regulatory compliance and stewardship, in addition to comprehensive standards and tools. We supplement our programs with our participation in trade associations which monitor developments in legislation impacting our businesses. Additionally, our Supplier Code of Conduct includes our expectations for our suppliers to comply with applicable laws and regulations and encourages them to adhere to the highest principles of environmental responsibility.

We follow the American Chemistry Council Responsible Care® Guiding Principles for our global facilities and products and last received third party certification of our Responsible Care® Management System in 2019. Many of our facilities have been certified to ISO 14001 and other ISO management systems. We have a mature corporate environmental, health and safety audit program for all of our facilities. We focus on emergency preparedness and crisis planning and drills, at both the facility and corporate level. We expect that stringent environmental regulations will continue to be imposed on us and our industry in general.

Sustainability and Climate Change

We recognize that climate change has had and will continue to have significant impacts on our environment, particularly as it relates to extreme weather conditions and rising sea levels, and which has prompted regulations limiting, among other things, the emission of greenhouse gases. In the countries in which we operate, particularly in the EU, we are required to comply with increasingly extensive regulations to address climate change impacts and resource conservation requirements.

We track and publicly report our greenhouse gas emissions, water usage, and energy consumptions and our facilities work to improve our performance at reducing chemical emissions, water usage and energy consumption. Our

18

Table of Contents

Sustainability and Corporate Social Responsibility Report, which is available on our website, provides our most recent sustainability highlights for our products, performance and operations. The report highlights sustainability goals and other initiatives to improve our sustainability performance. We do not expect the costs to comply with legislation enacted as a result of climate change and other sustainability efforts will be material to our operations and consolidated financial position in the next 12 months.

Environmental Remediation

Environmental laws and regulations require mitigation or remediation of the effects of the disposal or release of chemical substances. Under some of these regulations, as the current owner or operator of a property, we could be held liable for the costs of removal or remediation of hazardous substances on or under the property, without regard to whether we knew of or caused the contamination, and regardless of whether the practices that resulted in the contamination were permitted at the time they occurred. At our Allyn’s Point, Connecticut property we lease a portion of the property to our joint venture, Americas Styrenics, for its operations, which includes a regulated hazardous waste boiler, for which potential liabilities are addressed through financial assurance mechanisms and other agreements. Many of our production sites have an extended history of industrial use, and it is impossible to predict precisely what effect these laws and regulations will have on us in the future. Soil and groundwater contamination have occurred at some of the sites and might occur or be discovered at other sites. Subject to certain monetary and temporal limitations, Dow is obligated to indemnify and hold us harmless with respect to releases of hazardous material that existed at our sites prior to our separation from Dow in June 2010. The period for new claims at these sites has expired. Later-acquired sites are subject to a different limitations period. We cannot be certain that Dow will fully honor their existing indemnity obligations or that the indemnity will be sufficient to satisfy all claims that we may incur. We do not currently have any material obligations to perform environmental remediation on our properties, or for any Superfund site. Any active remedial projects on our properties which we acquired in 2010 are being performed by Dow pursuant to its indemnification obligations. We conduct comprehensive environmental due diligence for potential acquisitions to mitigate the risk of assuming obligations to conduct material levels of environmental remediation.

Government Regulation

In addition to environmental, health, and safety laws and regulations, our operations subject us to numerous federal, state, and local laws and regulations in the countries in which we operate. International trade laws and trade agreements, export and customs controls can limit the countries in which we can do business, or add significant cost to the import or export of our products or raw materials. Changes to or violations of these regulations could impact the costs of our goods or cause delay in shipments. Our products are also used in a variety of end-uses that have specific regulatory or consumer safety requirements such as those relating to food packaging or medical devices. Changes in these requirements could result in increased compliance costs, product recalls, or fines, which could prevent or inhibit the development and sale of our products. These and other laws and regulations impact the manner in which the Company conducts its business, and changes in legislation or government regulations can affect the Company’s global operations, both favorably and unfavorably. For a more detailed description of the various laws and regulations that affect the Company’s business, see Item 1A. Risk Factors.

Security

We recognize the importance of security and safety to our employees and the community. Physical security measures have been combined with process safety measures (including the use of technology) and emergency response preparedness into integrated security plans. We have conducted information security assessments at our operating facilities worldwide and identified and implemented appropriate measures to protect these facilities from physical and cyber-attacks. Effort and resources in assessing security requirements at our manufacturing facilities will continue, as required by U.S. Department of Homeland Security and other requirements.

19

Table of Contents

Trinseo has implemented information security solutions, resources, policies, programs, and monitoring alerts to respond to potential information security events and to maintain compliance with the increasing amount of data privacy laws and regulation.

Human Capital Resources and Objectives

As of December 31, 2020, we had approximately 2,600 employees worldwide. Nearly 69% of our personnel are located at the various manufacturing sites, research and development, pilot coating, paper fabrication and testing and technology centers. The remaining employees are located at operating centers, virtual locations or geographically dispersed marketing and sales locations. Our Midland, Michigan site is the only U.S. facility with union representation for its 55 hourly operations personnel. Employees at certain of our other locations are represented by work councils. We consider relations with our personnel and the various labor organizations to be good. There have been no labor strikes or work stoppages in these locations in recent history.

​

People Strategy

We strive to retain a talented, diverse and inclusive workforce and understand that our success requires ongoing investment in our employees. Our approach to attracting and retaining talent is our commitment to our core values of Responsible Care®, Innovation, Respect & Integrity, Accountability & Value Creation, and Commitment to Customers. As applied to our employees, these values prioritize health and safety, accountability and rewards for achievement, and treatment of all persons in our organization with respect, honesty, and dignity.

Our core values are reflected in the goals of our “People Strategy,” which is designed to support employees through Talent Management, Organizational Development, and Recognition & Rewards. Talent Management measures our ability to attract and select the right talent for the right roles, onboard new employees to improve integration, build critical capabilities, and develop leaders of the future, with a culture of collaboration among high-performing and diverse teams. Organizational Development focuses on the design of organization models to achieve our business strategies, assess employee engagement, evolve our culture and facilitate open communication. Recognition & Rewards means our efforts to manage, measure, and pay for performance; differentiate and recognize job growth with increases, promotions, and pay, annual performance awards and recognition of outstanding contributions from employees.

​

Environmental Protection and Employee Health & Safety (“EH&S”)

Focus on the safety of our employees is a critical aspect of our operations, and we strive towards achieving zero injuries, spills, or process safety incidents in our facilities every year. Our EH&S management system promotes a culture of rigorous investigation, corrective action, and continuous improvement applied over many years and has delivered a world-class set of internal safety policies, processes, and procedures. This system is designed to meet our objectives to continually reduce safety and environmental incidents and risks, maintain full regulatory compliance and optimize resources and continuously improve.

The Company has taken proactive steps to minimize the potential impact of the COVID-19 crisis on our employees. These steps include, but are not limited to: (i) encouraging or requiring our employees to work from home where possible or required by local laws and regulations; (ii) instituting masking and social distancing rules in our manufacturing and office locations; (iii) providing personal protective equipment; (iv) screening protocols; (v) implementing cleaning and other measures in the workplace; and (vi) conducting training for all employees. Corporate and regional COVID-19 crisis response teams lead the implementation of our pandemic response plans and other measures in our regions and at all our facilities in accordance with local requirements and guidance from the Center of Disease Control, local health departments and other health organizations. These measures have allowed us to protect worker safety while we strive to optimize production schedules, balance staffing needs, develop contingency plans, and enable the continued safe operation of our plants and facilities. We have not announced significant layoffs or employee furloughs as a result of the COVID-19 crisis.

​

Diversity and Equal Employment Opportunity

We are committed to maintaining an inclusive workforce that offers a diversity of perspectives, backgrounds and experience, and creating an environment in which all Trinseo employees have an equal opportunity to reach their potential and contribute fully to the success of the Company. Trinseo provides an equal employment opportunity, with a

20

Table of Contents

policy to recruit, hire, develop, and promote qualified applicants or employees without regard to race, religion, gender, sexual orientation, national origin, age or disability.

​

Talent Management and Employee Development

We provide opportunities for career development through a combination of training, coaching, and on-the-job experiences. We believe this approach to development provides our employees with the right balance of learning options. Further, we believe that early investment in our employees ensures that our future leaders have the skills they will need to be successful within a complex and ever-changing business environment. As part of our People Strategy, we conduct a talent review process that assesses our employee’s leadership behaviors, attributes, potential, and provides them with input on personal development. We also utilize a goal setting scorecard that enables employees to document and align their goals within a leadership team and across functions, which goals are set against annual Company priorities. Employees are evaluated on their performance versus individual goals and on the Company’s performance versus corporate goals (which includes financial and safety metrics). Part of the annual performance review process includes personal assessment goals which are tracked and reviewed throughout the year.

​

Compensation Policies

Trinseo’s process for determination of remuneration consists of two main components: base pay and an annual variable program, and we are committed to ensuring equitable compensation among our employees. As stated above, equal opportunity and diversity are important at Trinseo. We conduct internal reviews to assess fair treatment to determine if our pay practices are being implemented appropriately in all jurisdictions where we operate.

Volatility in the cost of energy or the raw materials utilized for our products, or disruption in the supply of the raw materials utilized for our products, may adversely affect our financial condition and results of operations or cause our financial results to differ materially from our forecasts.

Our results of operations can be directly affected, positively and negatively, by volatility in the cost of our raw materials, which are subject to global supply and demand and other factors beyond our control. Our principal raw materials (benzene, ethylene, butadiene, BPA, and styrene) together represent approximately 43% of our total cost of goods sold. Additionally, we use natural gas and electricity to operate our facilities and generate heat and steam for our various manufacturing processes. Crude oil prices also impact our raw material and energy costs. Generally, higher crude oil prices lead to higher costs of natural gas and raw materials, although some raw materials are impacted less than others. Volatility in the cost of energy or raw materials makes it more challenging to manage pricing and pass the increases on to our customers in a timely manner. We believe that rapid changes in pricing also can affect the volume our customers consume. As a result, our gross profit and margins could also be adversely affected and our financial results may differ materially from our forecasts.

We have supply agreements with Dow for ethylene, benzene, and butadiene, which are critical raw materials to our business. These raw materials and other less critical materials amount to approximately 29% of our total raw materials acquired in 2020, based on aggregate purchase price. The remainder is purchased via other third-party suppliers on a

21

global basis. As these and other third-party supply agreements expire, we may be unable to renegotiate or renew these contracts, or obtain new long-term supply agreements on terms comparable or favorable to us, or at all, which may significantly impact our operations. See Item 1—Business— Sources and Availability of Raw Materials.

If the availability of any of our principal raw materials is limited, we may be unable to produce some of our products in the quantities demanded by our customers, which could have an adverse effect on plant utilization and our sales of products requiring such raw materials. Suppliers may have temporary limitations preventing them from meeting our requirements, and we may not be able to obtain substitute alternative suppliers in a timely manner or on favorable terms.

Production at our manufacturing facilities could be disrupted for a variety of reasons. Disruptions could expose us to significant losses or liabilities.

The hazards and risks of disruption associated with chemical manufacturing and the related storage and transportation of raw materials, products and wastes exist in our operations and the operations of other occupants with whom we share manufacturing sites. These potential risks of disruption include, but are not necessarily limited to:

These hazards could expose employees, customers, the community and others to toxic chemicals and other hazards, contaminate the environment, damage property, result in personal injury or death, lead to an interruption or suspension of operations, damage our reputation and adversely affect the productivity and profitability of a particular manufacturing facility or us as a whole, and result in the need for remediation, governmental enforcement, regulatory shutdowns, the imposition of government fines and penalties, and claims brought by governmental entities or third parties. Legal claims and regulatory actions could subject us to both civil and criminal penalties, which could affect our product sales, reputation and profitability. Furthermore, the environmental, health and safety compliance, management systems, and emergency response and crisis management plans we have in place may not address or foresee all potential risks or causes of disruption.

If disruptions occur, alternative facilities with sufficient capacity or capabilities may not be available, may cost substantially more or may take a significant time to start production. Each of these scenarios could negatively affect our business and financial performance. If one of our key manufacturing facilities is unable to produce our products for an extended period of time, our sales may be reduced by the shortfall caused by the disruption and we may not be able to meet our customers’ needs, which could cause them to seek other suppliers. Furthermore, to the extent a production disruption occurs at a manufacturing facility that has been operating at or near full capacity, the resulting shortage of our product could be particularly harmful because production at the manufacturing facility may not be able to reach levels achieved prior to the disruption. Our insurance policies may not fully insure against all potential causes of disruption due to limitations and exclusions in those policies. Therefore, incidents that significantly disrupt our operations may expose us to significant losses and/or liabilities.

Capital projects and other growth investments may have lengthy deadlines during which market conditions may deteriorate between the capital expenditure’s approval date and the conclusion of the project, negatively impacting projected returns. If we are unable to execute on our capital projects or growth plans within their expected budget and timelines, or if the market conditions assumed in our projections deteriorate, our business, financial condition, results of operations and cash flows could be materially and adversely affected.

Delays or cost increases related to capital and other spending programs involving engineering, procurement and construction of facilities or manufacturing lines or the development of new technologies could materially adversely affect our ability to achieve forecasted operating results. Project delays or budget overages may arise as a result of unpredictable events, which may be beyond our control, including, but not limited to:

Furthermore, presumed demand for the technologies or products provided by the manufacturing facilities or lines being constructed or the technologies being developed may deteriorate during the project period. If we were unable to stay within a project’s overall timeline or budget, or if market conditions change, it could materially and adversely affect our business, financial condition, results of operations and cash flows.

If we are not able to continue the technological innovation and successful commercial introduction of new products, our customers may turn to other producers to meet their requirements.

Our industry and the end markets into which we sell our products experience periodic technological changes and ongoing product improvements. Our customers may introduce new generations of their own products or require new technological and increased performance specifications that would require us to develop customized products. Innovation or other changes in our customers’ product performance requirements may also adversely affect the demand for our products. Our future growth will depend on our ability to gauge the direction of the commercial and technological progress in all key end markets, and upon our ability to successfully develop, manufacture and market products in such changing end markets. We need to continue to identify, develop and market innovative products on a timely basis to replace existing products in order to maintain our profit margins and our competitive position. We may not be successful in developing new products and technology that successfully compete with these materials, and our customers may not accept any of our new products. If we fail to keep pace with evolving technological innovations or fail to modify our products in response to our customers’ needs, then our business, financial condition and results of operations could be adversely affected as a result of reduced sales of our products.

Risks Related to Acquisitions and Dispositions

We face risks concerning our recently announced proposed acquisition of assets from Arkema, S.A.

On December 14, 2020, we entered into a binding offer to acquire the Arkema business for a purchase price of €1.137 billion (the “Arkema Acquisition”). Pursuant to such offer, we entered into a put option agreement with Arkema (the “Put Option”) which includes a securities purchase agreement (“SPA”) and warranty agreement (“Warranty Agreement”). The Put Option provides Arkema the right to deliver a put option exercise notice within 10 business days of the completion of certain consultation processes with works councils, upon which we will execute and deliver the SPA and Warranty Agreement on the date and location set forth in the put option exercise notice. Once signed, the parties’ obligations to complete the transaction under the SPA will be subject to the absence of a material adverse change, the completion of certain pre-closing reorganizations, the receipt of certain antitrust clearances and other customary conditions and approvals, as well as the provision of certain financial information and cooperation with our arrangement of debt financing to fund the acquisition.

The Arkema Acquisition is expected to close in mid-2021, subject to these and other closing conditions. Not all of these closing conditions are within our control. It is possible that certain conditions or events may prevent, delay or

23

Table of Contents

otherwise materially adversely affect the completion of the Arkema Acquisition. We cannot predict with certainty whether and when any of the remaining required closing conditions will be satisfied, including the procurement of all antitrust, works councils and other regulatory approvals, or whether Arkema and the Company will be able to meet their pre-closing conditions. If the Arkema Acquisition does not receive required regulatory approvals, if a material adverse change occurs, or if another event occurs that delays or prevents the acquisition, our ability to complete the Arkema Acquisition could be materially adversely impacted. If the Company is unable to secure the financing necessary to fund the Arkema Acquisition, at terms acceptable to the Company, due to its failure to successfully access financial markets, failure by Arkema to meet its obligations under the SPA, adverse market conditions, or otherwise, we could fail to complete the Arkema Acquisition. Any such delay or failure to complete the Arkema Acquisition could cause uncertainty or other negative consequences that may materially and adversely affect our business, financial condition and results of operations and, to the extent that the current price of the Company’s common shares reflects an assumption that the Arkema Acquisition will be completed, the price of the Company’s common shares could be negatively impacted.

We may fail to realize the anticipated benefits of the Arkema Acquisition or such benefits may take longer to realize than expected. We may also encounter difficulty integrating the Arkema business into our operations.

Our ability to realize the anticipated benefits of the Arkema Acquisition will depend on our ability to integrate the Arkema business into ours. Combining these businesses will be a complex and time-consuming process. As a result, we expect to devote significant attention and resources preparing for and then integrating the operations, systems, processes, procedures and personnel of the acquired Arkema business. This integration process may be disruptive to our ongoing business, and, if we fail to effectively integrate, or if integration takes longer or is more costly than expected, we could lose or diminish the expected benefits of the Arkema Acquisition. Even if we are able to integrate the Arkema business successfully, this integration may not result in the realization of the synergies and benefits that we currently expect, nor can we give assurances that these benefits will be achieved when expected or at all.

We also face risks that the post-acquisition Company may fail to meet its financial and strategic goals, due to, among other things, inability to grow and manage growth profitability, maintain relationships with customers or retain key employees. The post-acquisition Company may also be adversely affected by other economic, business, and/or competitive factors which may not exist at the time of closing. Such conditions could materially adversely impact our business and results of operations. Further, costs of the acquisition could greatly exceed our anticipated costs, which could have a material adverse impact on our financial condition.

We may engage in strategic acquisitions or dispositions of certain assets and/or businesses that could affect our business, results of operations, financial condition and liquidity.

We may selectively pursue other complementary acquisitions and joint ventures, which inherently involves a number of risks and presents financial, managerial and operational challenges, including, but not limited to:

In addition, we may encounter unforeseen obstacles or costs in the integration of the Arkema business or other acquired businesses. Also, the presence of one or more material liabilities of an acquired company that are unknown to us at the time of acquisition may have a material adverse effect on our business or financial results. Our acquisition and joint venture strategy may not be successfully received by customers or other stakeholders, and we may not realize any anticipated benefits from the Arkema Acquisition, other acquisitions or joint ventures.

In December we announced the Company’s intent to explore the potential divestiture of our Synthetic Rubber business. We may also opportunistically pursue dispositions of certain other assets and/or businesses, which may involve material amounts of assets or lines of business, and adversely affect our results of operations, financial condition and liquidity. If any such dispositions were to occur, under the terms of our senior secured credit agreement (the “Credit Agreement”) governing our senior secured financing facility of up to $1,075.0 million (the “Senior Credit Facility”) and the indenture (the “Indenture”) governing our $500.0 million aggregate principal of 5.375% senior notes due 2025 (the

24

Table of Contents

“2025 Senior Notes”), we may be required to apply the proceeds of the sale to repay any borrowings under our Senior Credit Facility or our 2025 Senior Notes. Dispositions may also involve continued financial involvement in the divested business, such as through continuing equity ownership, transition service agreements, guarantees, indemnities or other current or contingent financial obligations.

Joint ventures may not operate according to their business plans if we or our partners fail to fulfill our or their obligations, or differences in views among our joint venture partners result in delayed decisions, which may adversely affect our results of operations and may force us to dedicate additional resources to these joint ventures.

For the year ended December 31, 2020, we received dividends of $15.0 million from our Americas Styrenics joint venture. We may enter into additional joint ventures in the future. The nature of a joint venture requires us to share control with unaffiliated third parties. If joint venture partners do not fulfill their obligations, the affected joint venture may not be able to operate according to its business plan. In that case, our results of operations may be adversely affected and we may be required to increase the level of our commitment to the joint venture. Differences in views among joint venture participants and our inability to unilaterally implement sales and production strategies or determine cash distributions from joint ventures may significantly impact short-term and longer-term financial results, financial condition and the value of our ordinary shares.

We may be unable to achieve cost savings and other benefits from our restructuring activities and business excellence initiatives.

In 2019, we announced a corporate restructuring plan associated with our shift to a global functional structure and adoption of our business excellence initiatives designed to create ongoing cost savings through business process optimization and efficiencies. Our efforts to achieve these improvements and efficiencies may not be successful or generate expected cost savings, and we may incur greater costs than currently anticipated to implement and achieve these initiatives, which could have an adverse impact on our financial condition or results of operations.

Risks Related to Regulation

We are subject to customs, international trade, export control, and antitrust laws that could require us to modify our current business practices and incur increased costs.

We are subject to numerous regulations, including customs and international trade laws, export/import control laws, and associated regulations. These laws and regulations limit the countries in which we can do business; the persons or entities with whom we can do business; the products which we can buy or sell; and the terms under which we can do business, including anti-dumping restrictions. In addition, we are subject to antitrust laws and zoning and occupancy laws that regulate manufacturers generally and/or govern the importation, promotion and sale of our products, the operation of factories and warehouse facilities and our relationship with our customers, suppliers and competitors. If any of these laws or regulations were to change or were violated by our management, employees, suppliers, buying agents or trading companies, the costs of certain goods could increase, or we could experience delays in shipments of our goods, be subject to fines or penalties, or suffer reputational harm, which could reduce demand for our products and hurt our business and negatively impact results of operations. In addition, in some areas we benefit from certain trade protections, including anti-dumping protection and the EU’s Authorized Economic Operator program, which provides expedited customs treatment for materials crossing national borders. If we were to lose these protections, our results of operations could be adversely affected.

Escalations in global trade conflicts, including the imposition of tariffs, may have a material adverse impact on our business and results of operations.

Various governments have adopted new approaches to their trade policies seeking to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements and implement new tariff schedules. For example, over the past several years the U.S. and China have applied tariffs to certain of each other’s exports. These measures have resulted in shifting trade flows and increased costs for raw materials and finished goods. Uncertainty over global tariffs or trade wars has and may continue to delay purchasing decisions by our customers as they assess the impact of

25

Table of Contents

such trade policies on their business. Further, the trade relationship between the United Kingdom and the EU as a result of Brexit could also negatively impact our customers’ purchasing decisions.

The adoption and expansion of trade restrictions, tariffs, or other governmental action has the potential to adversely impact demand for our products or our customers’ products, and our costs, including prices of raw materials, which in turn could adversely impact our business, financial condition and results of operations.

Regulatory and statutory changes applicable to our raw materials and products and our customers’ products and consumer preferences could require material expenditures, changes in our operations and could adversely affect our financial condition and results of operations.

Changes in environmental, health and safety regulations in jurisdictions where we manufacture and sell our products could lead to a decrease in demand for our products. In addition to changes in regulations, health, sustainability, and safety concerns could increase the costs incurred by our customers to use our products and otherwise limit the use of these products, which could lead to decreased demand for these products. Such a decrease in demand likely would have an adverse effect on our business and results of operations. Materials such as acrylonitrile, ethylbenzene, styrene, butadiene, BPA and halogenated flame retardant are used in the manufacturing of our products and have come under scrutiny due to potentially significant or perceived health and safety concerns. Moreover, bans on single-use plastic and similar regulatory actions to reduce plastic waste and consumer preferences for sustainable and recyclable materials may reduce the demand for some of our products over time. Legislation to place responsibility for addressing the global challenge of plastic waste may place responsibility on producers and sellers to include recycled content in their products, including the EU “plastics tax,” which legislation may impact our sales and place more importance on our initiatives to further develop technologies for recycled products.

Additionally, these regulatory regimes currently require significant compliance expenditures and future regulatory changes applicable to our raw materials and products or our customers’ products, could require significant additional expenditures or changes in our operations.

Our products are also used in a variety of end-uses that have specific regulatory requirements such as those relating to products that have contact with food or medical device end-uses. Our customers or distributors may not follow our policies and advice regarding the safe use and application of our products, which may unknowingly expose us to third-party claims. We and many of the applications for the products in the end markets in which we sell our products are regulated by various national and local rules, laws and regulations, such as the U.S. Toxic Substances Control Act and the EU’s Registration, Evaluation, Authorisation and Restriction of Chemicals regulations. An increasing number of countries continue to adopt similar requirements, which could require significant compliance expenditures or changes to our sales and marketing strategies and operations. Changes to existing regulations could result in additional compliance costs, seizures, confiscations, recall or monetary fines, any of which could prevent or inhibit the development, distribution and sale of our products. Changes in environmental and safety laws and regulations banning or restricting the use of these residual materials in our products, or our customers’ products, could adversely affect our results of operations and financial condition. Failure to appropriately manage safety, human health, product liability and environmental risks associated with our products, product life cycles and production processes could adversely impact employees, communities, stakeholders, our reputation and the results of our operations.

Compliance with extensive and evolving environmental, health and safety laws may require substantial expenditures.

We use large quantities of hazardous substances, generate hazardous wastes and emit wastewater and air pollutants in our manufacturing operations. Consequently, our operations are subject to extensive environmental, health and safety laws and regulations at both the national and local level in multiple jurisdictions. Many of these laws and regulations have become more stringent over time and the costs of compliance with these requirements may continue to increase, including costs associated with any capital investments for pollution control facilities. In addition, our production facilities and operations require operating permits, licenses or other approvals that may be subject to periodic renewal and, in circumstances of noncompliance, may be subject to revocation. The necessary licenses, permits or other approvals may not be issued or continue in effect, and any issued licenses, permits or approvals may contain more stringent limitations that restrict our operations or that require further expenditures to meet the permit requirements.

26

Table of Contents

This continuing focus on climate change in jurisdictions in which we operate has and will continue to result in new environmental regulations that may require us to incur additional costs in complying with new regulatory and customer requirements, which may adversely impact our operations and financial condition. Compliance with more stringent environmental requirements would likely increase our costs of transportation and storage of raw materials and finished products, as well as the costs of storage and disposal of wastes. Additionally, we may incur substantial costs, including penalties, fines, damages, criminal or civil sanctions and remediation costs for the failure to comply with these laws or permit requirements.

Trinseo Europe GmbH, one of our subsidiaries, received a Request for Information from the European Commission Directorate General for Competition, involving commercial activity for styrene monomer. To the extent the European Commission’s inquiry would lead to a finding that the Company’s subsidiary violated the law, the results of this finding could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

On June 6, 2018, Trinseo Europe GmbH, a subsidiary of the Company, received a Request for Information in the form of a letter from the European Commission Directorate General for Competition (the “European Commission”) related to styrene monomer commercial activity in the European Economic Area. In addition, the Company commenced an internal investigation into the matter and has discovered instances of inappropriate activity. On October 28, 2019, a supplemental request for information was received from the European Commission. This request was limited to historical employment, entity, and organizational structures, along with certain financial, styrene purchasing, and styrene market information, as well as certain spot styrene purchase contracts. We have provided this information to the European Commission and continue to fully cooperate with the Request for Information.

This matter remains open with the European Commission. We are unable to make any predictions regarding the ultimate outcome of our response to the European Commission’s request.

Based on its findings, the European Commission may decide to: (i) require further information; (ii) conduct unannounced raids of the Company’s premises; (iii) adopt decisions imposing fines, interim measures to halt immediately any anti-competitive behavior, orders for the Company to cease anti-competitive activities, and/or certain behavioral or structural commitments from the Company; or (iv) take no further action. If Trinseo Europe GmbH is found to have violated one or more laws, it could also be subject to additional actions by local competition authorities. European Commission inquiries or investigations can continue over a long period of time, which can divert the attention of our management from day-to-day operations and impose significant administrative burdens. Any of these consequences could damage our reputation and impair our ability to conduct business, which could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

We may be subject to losses due to liabilities or lawsuits related to contaminated land we own or operate or arising out of environmental damage or personal injuries associated with exposure to chemicals or the release of chemicals.

Under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) and similar statutes outside the U.S., the current or former owner or operator of a property contaminated by hazardous substance releases is subject to strict, unlimited, joint, several and retroactive liability for the investigation and remediation of the property, and also may be liable for natural resource damages associated with the releases. In addition to potential statutory liability, we also face the risk that individuals could seek damages for personal injury due to exposure to chemicals at our facilities, chemicals which have been released from our facilities, chemicals otherwise owned or controlled by us, or chemicals which allegedly migrated from products containing our materials. We may be subject to claims with respect to workplace exposure, workers’ compensation and other health and safety matters. Legal claims and regulatory actions could subject us to both civil and criminal penalties, which could affect our reputation as well as our results of operations, financial condition, and liquidity.

There are several properties which we now own on which Dow has been conducting remediation to address historical contamination. Those properties include Allyn’s Point, Connecticut and Dalton, Georgia. There are other properties with historical contamination that are owned by Dow that we lease for our operations, including our facility in Midland, Michigan. While we did not assume the liabilities associated with these properties in the U.S., because CERCLA and similar laws can impose liability for contamination on the current owner or operator of a property, even if it did not create the contamination, there is a possibility that a governmental authority or private party could seek to

27

Table of Contents

include us in an action or claim for remediation or damages, even though the contamination may have occurred prior to our ownership or occupancy. While Dow has agreed to indemnify us for liability for releases of hazardous materials that occurred prior to our separation from Dow, the indemnity is subject to monetary and temporal limitations. The period for new claims at these sites has expired. Later-acquired sites are subject to a different limitations period. We do not currently have any material obligations to perform environmental remediation on our properties, or for any Superfund site. Any active remedial projects on our properties which we acquired in 2010 are being performed by Dow pursuant to its indemnification obligations. We cannot be certain that Dow will fully honor the indemnity or that the indemnity will be sufficient to satisfy all claims that we may incur. In addition, we face the risk that future claims might fall partially or fully outside of the scope of the indemnity, particularly if there is a release of hazardous materials that occurs in the future or at any time after our separation from Dow or if the condition requiring remediation is attributable to a combination of events or operations occurring prior to and after our separation from Dow.

Risks Related to Our Relationship with Dow

Dow provides significant operating and other services, and certain raw materials used in the production of our products, under agreements that are important to our business. The failure of Dow to perform its obligations, or the termination of these agreements, could adversely affect our operations.

Prior to our inception, we were operated by Dow, which has provided and continues to provide services under certain agreements that are important to our business. We are a party to:

Under the terms of the above agreements, either party is also permitted to terminate the applicable agreement in a variety of situations, including in the event of the other party’s uncured material breach, insolvency, change of control or cessation of operations. Should Dow fail to provide these services or raw materials, or should any of the above agreements be terminated, we would be forced to obtain these services and raw materials from third parties or provide them ourselves. Additionally, if Dow terminates agreements pursuant to which we are obligated to provide certain services, we may lose the fees received by us under these agreements. The failure of Dow to perform its obligations under, or our inability to renegotiate, renew or replace any of these contracts, particularly without an alternative source of raw materials, could adversely affect our operations. Depending on market conditions at the time of any such termination, we may not be able to enter into substitute arrangements in a timely manner, on terms as favorable to us or at all. For more information regarding our relationship with Dow, please see Item 1—Business — Our Relationship with Dow.

Our migration away from services and technologies provided by Dow may cause significant disruptions to operations that could materially adversely affect our future results, business and financial condition.

From 2018 through the first half of 2020, the Company worked to insource, and in some cases outsource to other vendors, certain information technology, procurement, supply chain, finance, and ERP services and systems that were being provided by Dow. By mid-2020, the Company substantially completed the transition of the services covered under the SAR MOSA. Additionally, the Company is continuing to migrate our manufacturing facilities away from Dow’s MOD5 process controller technology over the next several years.

During 2020, 2019, and 2018, the Company incurred $24.6 million, $68.1 million, and $26.1 million in costs, respectively, related to our transition of these services away from Dow, of which $6.5 million, $21.8 million and $5.7 million, respectively, was capitalized and $18.1 million, $46.3 million and $20.4 million, respectively, was recognized as expense. The Company does not expect to incur any further significant costs related to transitioning services away from Dow under the SAR MOSA in 2021, however unanticipated future capital expenditures or additional expense associated with the migrations may reduce the Company’s cash position and profitability, respectively. We cannot assure that there will not be associated excessive costs, disruptions or other negative impacts in portions of our business in the course of our migration of these services and systems. Any prolonged disruption in the operations of our existing manufacturing facilities, supply chain, distribution or other operations, whether due to technical or integration difficulties, could have a

28

Table of Contents

material adverse effect on our business, reputation, future sales, financial condition and results of operations. For more information regarding our relationship with Dow, please see Item 1—Business — Our Relationship with Dow.

We are party to certain license agreements with Dow relating to intellectual property that is essential to our business. Because of this relationship, we may have limited ability to expand our use of certain intellectual property beyond the field of the license or to police infringement that may be harmful to our business.

In connection with our separation from Dow, we acquired ownership of, or in some cases, a worldwide right and license to use, certain patents, patent applications and other intellectual property of Dow that were used by Dow to operate our business segments or held by Dow primarily for the benefit of our business segments, prior to the Acquisition. Generally, we acquired ownership of the intellectual property that was primarily used in our business segments and acquired a license to a more limited set of intellectual property that had broader application within Dow beyond our core business segments. Our license from Dow is perpetual, irrevocable, fully paid, and royalty-free. Furthermore, our license from Dow is exclusive within our business segments for certain patents and patent applications that were used by Dow primarily prior to our separation, subject to licenses previously granted by Dow, and to certain retained rights of Dow, including Dow’s retained right to use patents and patent applications outside of our business segments and for internal consumption by Dow. Our license from Dow relates to polymeric compositions, manufacturing processes and end applications for the polymeric compositions; and is limited to use in defined areas corresponding to our current business segments excluding certain products and end-use application technology retained by Dow. Our ability to develop, manufacture or sell products and technology outside of these defined areas may be impeded by the intellectual property rights that have been retained by Dow, which could adversely affect our business, financial condition and results of operations. Additionally, infringement on these intellectual property rights could also impact our business and competitive position. We may not be able to enforce our rights, and Dow may be unwilling to enforce its rights, with respect to this intellectual property that has been licensed by Dow.

Risks Related to Our Indebtedness

Our current and future level of indebtedness of our subsidiaries, including the incurrence of additional indebtedness to fund the Arkema Acquisition, could adversely affect our financial condition.

As of December 31, 2020, our indebtedness totaled approximately $1.2 billion. Additionally, as of December 31, 2020, we had $360.0 million (net of $15.0 million outstanding letters of credit) of funds available for borrowings under our Senior Credit Facility, as well as $150.0 million of funds available for borrowings under our accounts receivable securitization facility (the “Accounts Receivable Securitization Facility”).

Additionally, in connection with the Arkema Acquisition, our Trinseo Materials Operating S.C.A. and Trinseo Materials Finance Inc. subsidiaries entered into a debt commitment letter with Deutsche Bank AG New York Branch, Deutsche Bank AG Cayman Islands Branch, Deutsche Bank Securities Inc., HSBC Bank USA, N.A., and HSBC Securities (USA) Inc. (the “Commitment Parties”), pursuant to which the Commitment Parties have committed, subject to certain customary terms and conditions, to provide (i) a senior secured credit facility in an aggregate principal amount of $400.0 million, (ii) a secured bridge facility in an aggregate principal amount of $350.0 million and (iii) an unsecured bridge facility in an aggregate principal amount of $450.0 million (the “Bridge Commitment”).

We intend to seek debt financing to fund the Arkema Acquisition through a combination of term loan and senior notes, which would forego the need to utilize the Bridge Commitment. We may not be successful in raising new indebtedness at terms more favorable than our existing indebtedness, or at all. Our level of indebtedness, as well as future borrowings under the Bridge Commitment or other indebtedness at the anticipated levels required to close the Arkema Acquisition, could have significant consequences for our business, including but not limited to:

29

Table of Contents

Although the Credit Agreement and the Indenture contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions and the indebtedness incurred in compliance with these restrictions could be substantial. Also, we are not prevented from incurring obligations that do not constitute “indebtedness” as defined in the Senior Credit Facility or the Indenture, such as operating leases and trade payables. If new debt is added to our subsidiaries’ current debt levels, the risks related to indebtedness that we now face could intensify.

In addition, a substantial portion of our subsidiaries’ current indebtedness is secured by substantially all of our assets, which may make it more difficult to secure additional borrowings at reasonable costs. If we default or declare bankruptcy, after these obligations are met, there may not be sufficient funds or assets to satisfy our subordinate interests, including those of our shareholders. For more information regarding our indebtedness, please see Item 7—Management’s Discussion and Analysis of Financial Conditions and Results of Operations— Capital Resources, Indebtedness and Liquidity.

The terms of our subsidiaries’ indebtedness may restrict our current and future operations, particularly our ability to respond to change or to take certain actions.

The Indenture and the Credit Agreement governing our Senior Credit Facility contain a number of covenants imposing certain restrictions on our subsidiaries’ businesses. These restrictions may affect our ability to operate our business and may limit our ability to take advantage of business opportunities. These agreements restrict, among other things, our subsidiaries’ ability to:

The ability of our subsidiaries to comply with the covenants and financial ratios and tests contained in the Indenture and Credit Agreement, to pay interest on indebtedness, fund working capital, and make anticipated capital expenditures depends on our future performance, which is subject to general economic conditions and other factors, some of which are beyond our control. There can be no assurance that our business will generate sufficient cash flow from operations or that future borrowings will be available under our Senior Credit Facility to fund liquidity needs in an amount sufficient to enable them to service their indebtedness. Furthermore, if we need additional capital for general corporate purposes or to execute on an expansion strategy, there can be no assurance that this capital will be available on satisfactory terms or at all.

A failure to repay amounts owed under the Senior Credit Facility or 2025 Senior Notes at maturity would result in a default. In addition, a breach of any of the covenants in the Credit Agreement or Indenture or our inability to comply with the required financial ratios or limits could result in a default. If a default occurs, lenders may refuse to lend us additional funds and the lenders or noteholders could declare all of the debt and any accrued interest and fees immediately due and payable. A default under one of our subsidiaries’ debt agreements may trigger a cross-default under

30

our other debt agreements. For more information regarding our indebtedness, please see Item 7—Management’s Discussion and Analysis of Financial Conditions and Results of Operations— Capital Resources, Indebtedness and Liquidity.

Risks Related to Our Intellectual Property

Our business relies on intellectual property and other proprietary information and our failure to adequately protect or effectively enforce our rights could harm our competitive advantages with respect to the manufacturing of some of our products.

Our success depends to a significant degree upon our ability to protect, preserve and enforce our intellectual property rights, including patents, trademarks, licenses, trade secrets and other proprietary information of our business. However, we may be unable to prevent third parties from using our intellectual property and other proprietary information without our authorization or independently developing intellectual property and other proprietary information that is similar to or competes with ours. Any inability by us to effectively prevent the unauthorized use of our intellectual property and other proprietary information by others could reduce or eliminate any competitive advantage we have developed, cause us to lose sales or otherwise harm our business or goodwill. If it becomes necessary for us to initiate litigation to protect our proprietary rights, any proceedings could be burdensome and costly, and we may not prevail.

We may be unable to determine when third parties are using our intellectual property rights without our authorization, particularly our manufacturing processes. In addition, we cannot be certain that any intellectual property rights that we have licensed to third parties are being used only as authorized by the applicable license agreement. The undetected, unremedied, or unauthorized use of our intellectual property rights or the legitimate development or acquisition of intellectual property that is similar to or competes with ours by third parties could reduce or eliminate the competitive advantage we have as a result of our intellectual property, adversely affecting our financial condition and results of operations.

If we fail to adequately protect our intellectual property and other proprietary information, including our processes, apparatuses, technology, trade secrets, trade names and proprietary manufacturing know how, methods and compounds, through obtaining patent protection, securing trademark registrations and securing our trade secrets through the use of confidentiality agreements of appropriate scope and other means, our competitive advantages over other producers could be materially adversely affected. If we determine to take legal action to protect, defend or enforce our intellectual property rights, any suits or proceedings could result in significant costs and diversion of our resources and our management’s attention. We may not prevail in any such suits or proceedings. A failure to protect, defend or enforce our intellectual property rights could have an adverse effect on our financial condition and results of operations.

Our products may infringe the intellectual property rights of others, which may cause us to incur unexpected costs or prevent us from selling our products.

Many of our competitors have a substantial amount of intellectual property that we must continually strive to avoid infringing as we improve our own business processes and develop new products and applications. Although it is our policy and intention not to infringe valid patents of which we are aware, we cannot provide assurances that our processes and products and other activities do not and will not infringe issued patents (whether present or future) or other intellectual property rights belonging to others. There nonetheless could be third-party patents that cover our products, processes or technologies, and it is possible that we could be liable for infringement of such patents and could be required to take remedial or curative actions to continue our manufacturing and sales activities with respect to one or more products that are found to be infringing. We may also be subject to indemnity claims by our business partners arising out of claims of their alleged infringement of the patents, trademarks and other intellectual property rights of third parties in connection with their use of our products. Intellectual property litigation often is expensive and time-consuming, regardless of the merits of any claim, and our involvement in such litigation could divert our management’s attention from operating our business. If we were to discover that any of our processes, technologies or products infringe on the valid intellectual property rights of others, we may not be able to obtain the necessary licenses on acceptable terms, or at all, or be able to modify our processes or technologies or re-engineer our products in a manner that is successful in avoiding infringement. Moreover, if we are sued for infringement and lose, we could be required to pay substantial damages and/or be enjoined from using or selling the infringing products or technology. Any of the foregoing

could cause us to incur significant costs and prevent us from selling our products and could have an adverse effect on our financial condition and results of operations.

Risks Related to Data Security

Data security breaches could compromise sensitive information related to our business or the private information of our employees, vendors, and customers, which could adversely affect our business and our reputation.

Cyber-attacks or data security breaches could compromise confidential, private, business critical information or cause a failure in our computer or operating systems that may disrupt our operations. We have attractive information assets, including intellectual property, trade secrets and other sensitive, business critical information. We face an ever-growing risk of attack from outside our organization (including attack by organized crime, so-called “hacktivists,” and state-sponsored actors) using sophisticated technical and non-technical methodologies (including social engineering and “spear phishing” attacks). We also face risks from internal threats to information security, such as from negligent or dishonest employees or consultants. A successful cyber-attack or other breach of security could result in the loss of critical business information and/or could negatively impact operations, which could have a negative impact on our financial results. Furthermore, in addition to using our own systems and infrastructure, we use information systems and infrastructure operated by third-party service providers, including Dow. If our third-party service providers experience an information security breach, depending on the nature of the breach, it could compromise confidential, business critical information or cause a disruption in our operations. In addition, the loss or disclosure of sensitive or private information about our employees, vendors, or customers as a result of such a breach may result in violations of various data privacy regulations and expose us to litigation, fines and other penalties. Therefore, any such disruptions to our operations or violations of data privacy laws could negatively impact our reputation and results of operations.

Risks Related to Our Ordinary Shares

We are a Luxembourg company and, as a result, shareholders may have difficulty effecting service of process or litigation against us or our officers and directors.

We are organized under the laws of the Grand Duchy of Luxembourg. Many of our assets are located outside the United States and some of our directors and officers reside outside the United States and most of their assets are located outside the United States. As a result, investors may find it more difficult to effect service of process within the United States upon us or these persons or to enforce outside the United States judgments obtained against us or these persons in U.S. courts, including judgments in actions predicated upon the civil liability provisions of the U.S. federal securities laws. Likewise, it may also be difficult for an investor to enforce in U.S. courts judgments obtained against us or these persons in courts located in jurisdictions outside the United States, including actions predicated upon the civil liability provisions of the U.S. federal securities laws. It may also be difficult for an investor to bring an original action in a Luxembourg court predicated upon the civil liability provisions of the U.S. federal securities laws against us or these persons. Luxembourg law does not recognize a shareholder’s right to bring a derivative action on behalf of a company.

General Risks

Conditions in the global economy and capital markets may adversely affect our results of operations, financial condition and cash flows.

Our products are sold in markets that are sensitive to changes in general economic conditions, such as sales of automotive and construction products. Downturns in general economic conditions can cause fluctuations in demand for our products, product prices, volumes and margins.

Turbulence in the credit markets, fluctuating commodity prices, volatile exchange rates and other challenges affecting the global economy can affect us and our customers. Instability and uncertainty in financial and commodity markets throughout the world may cause, among other things, severely diminished liquidity and credit availability, rating downgrades of certain investments and declining valuations and pricing volatility of others, volatile energy and raw material costs, geopolitical issues and failure and the potential failure of major financial institutions. Adverse events affecting the health of the economy, including sovereign debt and economic crises, refugee crises, disease pandemics, terrorism, Brexit, protectionism, tariffs, and the threat of war, could have a negative impact on the health of the global

economy. These developments, or the perception that any of them could occur, may have a material adverse effect on global economic conditions or on the stability of global financial markets. During any period of uncertainty or heightened market volatility, consumer confidence may decline which could lead to a decline in demand for our products or a shift to lower-margin products, which could adversely affect sales of our products and our profitability and could also result in impairments of certain of our assets.

Deterioration in the financial and credit market heightens the risk of customer bankruptcies and delay in payment. We are unable to predict the duration of the current economic conditions or their effects on financial markets, our business and results of operations. If economic conditions deteriorate, our results of operations, financial condition and cash flows could be materially adversely affected.

As a global business, we are exposed to local business risks in different countries, which could have a material adverse effect on our financial condition or results of operations.

We have significant operations worldwide, including manufacturing facilities, R&D facilities, sales personnel and customer support operations. As of December 31, 2020, we operated, or others operated on our behalf, 32 manufacturing plants (which include a total of 75 production units) at 24 sites around the world, including in Colombia, Germany, The Netherlands, Belgium, Finland, Sweden, Italy, China, South Korea, Indonesia, Taiwan, and the United States. Our international operations are subject to risks inherent in doing business in foreign countries, including, but not necessarily limited to:

We may not be successful in developing and implementing policies and strategies to address the foregoing factors in a timely and effective manner at each location where we do business. Consequently, the occurrence of one or more of the foregoing factors could have a material adverse effect on our international operations or upon our financial condition and results of operations.

Our operations in developing markets could expose us to political, economic and regulatory risks that are greater than those we may face in established markets. For example, we operate in some nations that have experienced significant levels of governmental corruption. Any failure by us to ensure that our employees and agents comply with applicable laws and regulations in foreign jurisdictions could result in substantial civil and criminal penalties or restrictions on our ability to conduct business in certain foreign jurisdictions or reputational damage, and our results of operations and financial condition could be materially and adversely affected.

Fluctuations in currency exchange rates may significantly impact our results of operations and may significantly affect the comparability of our results between financial periods.

Our operations are conducted by subsidiaries in many countries. The results of the operations and the financial position of these subsidiaries are reported in the relevant foreign currencies and then translated into U.S. dollars at the applicable exchange rates for inclusion in our consolidated financial statements. The main currency to which we are exposed is the euro, as approximately 57% of our net sales were generated in Europe in 2020. To a lesser degree, we are also exposed to other currencies, including the Chinese yuan, Swiss franc, and Indonesian rupiah. The exchange rates between these currencies and the U.S. dollar have fluctuated significantly in recent years and may continue to do so in the future. A depreciation of these currencies against the U.S. dollar, in particular the euro, will decrease the U.S. dollar equivalent of the amounts derived from these operations reported in our consolidated financial statements and an appreciation of these currencies will result in a corresponding increase in such amounts. Because some of our raw material costs are procured in U.S. dollars rather than on these currencies, depreciation of these currencies may have an adverse effect on our profit margins or our reported results of operations. Conversely, to the extent that we are required to pay for goods or services in foreign currencies, the appreciation of such currencies against the U.S. dollar will tend to negatively impact our results of operations. In addition, currency fluctuations may affect the comparability of our results of operations between financial periods.

We incur currency translation risk whenever we enter into either a purchase or sale transaction using a currency other than the local currency of the transacting entity. From time to time, we enter into foreign exchange forward contracts to hedge fluctuations associated with certain monetary assets and liabilities, primarily accounts receivable, accounts payable and certain intercompany obligations. However, attempts to hedge against foreign currency fluctuation risk may be unsuccessful, and we may not be able to effectively limit our exposure to intermediate or long-term movements in currency exchange rates, which could adversely impact our financial condition or results of operations. Given the volatility of exchange rates, there can be no assurance that we will be able to effectively manage our currency translation risks or that any volatility in currency exchange rates will not have a material adverse effect on our financial condition or results of operations.

The extent to which the COVID-19 pandemic will adversely impact our business, financial condition and results of operations is highly uncertain and cannot be predicted but could be material.

The COVID-19 pandemic has created significant worldwide volatility, uncertainty and disruption. The COVID-19 pandemic has resulted in a substantial curtailment of business activities, a significant number of business closures, suspensions or delays of production and commercial activity, government-mandated “shelter-in-place” and travel restrictions, and weakened economic conditions in the countries in which we operate.

The extent to which the COVID-19 pandemic will ultimately adversely impact our business, liquidity, financial condition and results of operations, which impact could be material, depends on numerous factors that are highly uncertain and cannot be predicted at this time. These factors include the duration and scope of the COVID-19 pandemic, including an increased spread of infections or new variants of the virus; renewed or extended travel restrictions and “shelter-in-place” directives; changes in customer demand; our relationship with, and the financial and operational capacities of, our customers and suppliers; impacts of raw material and feedstock prices affecting the cost competitiveness of our operations relative to similar operations in other regions; the health and safety of our employees and costs incurred to keep our employees safe while maintaining continued operations, including our ability to adjust our production schedules; potential future restructuring, impairment and other charges; and the impact on economic activity generally, including a global or national recession, or other sustained adverse market conditions.

Uncertain or depressed economic conditions, continued high unemployment or a decline in consumer confidence as a result of the pandemic could have an adverse effect on demand for our products and our customers’ products or otherwise adversely alter customer demand patterns which may negatively impact our business, liquidity, financial condition and results of operations.

The COVID-19 pandemic, including the impact of an increased spread of infections and renewed or extended travel restrictions, may also disrupt our supply chain, our transportation and logistics networks, including the ability of our third party suppliers’ or logistics and transportation service providers to meet their obligations to us, which may negatively affect our operations. Ports and other channels of entry may be closed or operate at only a portion of capacity, and means of transporting products within regions or countries in which we operate may be limited. Plant closures,

production delays, or logistics difficulties resulting from the COVID-19 pandemic may cause shortages or limited availability of feedstocks or raw materials that are used in our products, which may adversely impact our business, production capacity or results of operations.

While the Company has maintained a strong liquidity position, the effects of the COVID-19 pandemic may create additional risks related to our liquidity and financial results, including risks associated with our indebtedness, including available capacity, compliance with financial covenants; risks related to the adequacy of our cash flow and earnings and other conditions which may affect our liquidity; and risks related to our ongoing ability to pay our quarterly dividend at prior levels.

Our efforts to manage and mitigate these factors and risks through cost-savings and other measures may not be successful and are subject to the factors described above, many of which are uncertain or outside of our control. Business disruptions relating to the COVID-19 pandemic, including the impact of an increased spread of infections and renewed or ongoing travel restrictions could negatively impact economies in the countries in which we operate, which would adversely impact our business and results of operations.
