(All comparisons are against the prior year)

JERSEY CITY, NJ – May 11, 2022 – Amdocs Limited (NASDAQ: DOX), a leading provider of software and services to communications and media companies, today reported operating results for the three months ended March 31, 2022.

“I am excited to report another very strong quarter for Amdocs as we continued to enable our customer’s strategy to provide a superior mobile and broadband experience by supporting their long-term investments in 5G monetization, cloud adoption, digital modernization, and network automation. Record revenue of $1.15 billion was up 10.1% in constant currency⁽³⁾ from a year ago, reflecting strong business activity building next-generation platforms for large customers like AT&T, T-Mobile, and Vodafone Germany under multi-year programs. Sales momentum was also strong in Q2 and included a digital transformation project award with VodafoneZiggo in Netherlands, and a new 5G policy deal which expands our footprint at a leading Tier 1 European operator. Overall, we ended the fiscal second quarter with record-high 12-month backlog of $3.89 billion, which was up nearly 10% from a year ago,” said Shuky Sheffer, president and chief executive officer of Amdocs Management Limited.

“Demonstrating great execution in Q2, we set another company record for the number of quarterly milestones deployed. Our accomplishments included the go-live of a major digital transformation project for Three UK in just 15 months, highlighting our unrivalled reputation for project delivery. This was also a record quarter in managed services, driven by

continued growth with new and existing customers. At Bell Canada, we signed a five-year managed services extension that expands our long-term strategic relationship in support of Bell’s continued cloud transformation. Additionally, we strengthened our partnership with PLDT in the Philippines, where this leading operator awarded Amdocs a three-year extension of our existing managed services agreement through 2028, in addition to future projects to support PLDT’s cloud journey,” said Tamar Rapaport-Dagim, chief financial officer & chief operating officer of Amdocs Management Limited.

Sheffer concluded, “Our growth strategy is highly aligned with the needs of the market, and we see an expanding pipeline of opportunities ahead of us which we are well positioned to monetize with our market-leading products, best-in-class execution and highly talented people. Moreover, we are tracking in line with the high end of our fiscal 2022 revenue growth outlook of 8.0% to 10.0% on a pro forma⁽²⁾, constant currency⁽³⁾ basis, our confidence in which is supported by the business momentum reflected in our record 12-month backlog at the halfway point in the year.”

Non-GAAP Financial Measures

This release includes non-GAAP diluted earnings per share and other non-GAAP financial measures, including free cash flow and normalized free cash flow, revenue on a constant currency⁽³⁾ basis, non-GAAP cost of revenue, non-GAAP research and development, non-GAAP selling, general and administrative, non-GAAP operating income, non-GAAP operating margin, non-GAAP interest and other expenses, net, non-GAAP income taxes, non-GAAP effective tax rate, non-GAAP net income and non-GAAP diluted earnings per share growth. These other non-GAAP measures exclude the following items:

Free cash flow equals cash generated by operating activities less net capital expenditures and other. Normalized free cash flow, a measure of our operating performance, is further adjusted to exclude net capital expenditures related to the new campus development, payments for non-recurring and unusual charges (such as capital gains tax in relation to the divestiture of OpenMarket), and payments of acquisition related liabilities. These non-

GAAP financial measures are not in accordance with, or an alternative for, generally accepted accounting principles and may be different from non-GAAP financial measures used by other companies. In addition, these non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles. Amdocs believes that non-GAAP financial measures have limitations in that they do not reflect all of the amounts associated with Amdocs’ results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate Amdocs’ results of operations in conjunction with the corresponding GAAP measures.

Amdocs believes that the presentation of non-GAAP diluted earnings per share and other financial measures, including free cash flow and normalized free cash flow, non-GAAP cost of revenue, non-GAAP research and development, non-GAAP selling, general and administrative, non-GAAP operating income, non-GAAP operating margin, non-GAAP interest and other expenses, net, non-GAAP income taxes, non-GAAP effective tax rate, non-GAAP net income and non-GAAP diluted earnings per share growth when shown in conjunction with the corresponding GAAP measures, provides useful information to investors and management regarding financial and business trends relating to its financial condition and results of operations, as well as the net amount of cash generated by its business operations after taking into account capital spending required to maintain or expand the business.

For its internal budgeting process and in monitoring the results of the business, Amdocs’ management uses financial statements that do not include amortization of purchased intangible assets and other acquisition-related costs, changes in certain acquisition-related liabilities measured at fair value, non-recurring and unusual charges or benefits, equity-based compensation expense, other and related tax effects. Amdocs’ management also uses the foregoing non-GAAP financial measures, in addition to the corresponding GAAP measures, in reviewing the financial results of Amdocs. In addition, Amdocs believes that significant groups of investors exclude these items in reviewing its results and those of its competitors, because the amounts of the items between companies can vary greatly depending on the assumptions used by an individual company in determining the amounts of the items.

Amdocs further believes that, where the adjustments used in calculating non-GAAP diluted earnings per share are based on specific, identified amounts that impact different line items in the Consolidated Statements of Income (including cost of revenue, research and development, selling, general and administrative, operating income, interest and other expenses, net, income taxes and net income), it is useful to investors to understand how these specific line items in the Consolidated Statements of Income are affected by these adjustments.
