ST. LOUIS – January 30, 2013 – Amdocs Limited (NYSE: DOX) today reported that for its fiscal quarter ended December 31, 2012, revenue was $826.4 million, up 0.5% sequentially from the fourth fiscal quarter of 2012 and up 2.4% as compared to last year’s first fiscal quarter. Net income on a non-GAAP basis was $119.4 million, or $0.73 per diluted share, compared to non-GAAP net income of $111.3 million, or $0.64 per diluted share, in the first quarter of fiscal 2012. Non-GAAP net income excludes amortization of purchased intangible assets and other acquisition related costs and equity-based compensation expenses of $20.4 million, net of related tax effects, in the first quarter of fiscal 2013 and excludes such amortization and other acquisition related costs and equity-based compensation expenses of $18.5 million, net of related tax effects, in the first quarter of fiscal 2012. The Company’s GAAP net income for the first quarter of fiscal 2013 was $99.0 million, or $0.61 per diluted share, compared to GAAP net income of $92.7 million, or $0.53 per diluted share, in the prior fiscal year’s first quarter.

“We began fiscal 2013 with a record quarter for revenue that was partly driven by a return to year-on-year growth in our North American market. Specifically, we see renewed momentum at AT&T, which is focused on the implementation of its new strategy, including data monetization. In our emerging markets, we delivered 19% year-on-year growth in the first quarter and we are on-track to achieve our goal of double-digit growth in this region in fiscal 2013. In Europe, we experienced year-on-year declines owing to difficult macroeconomic conditions and the anticipated ramp down of some transformation projects with certain customers. However, we believe our competitive position in Europe remains strong, and we continue to see opportunities for new business across our portfolio of products and services” said Eli Gelman, chief executive officer of Amdocs Management Limited.

Gelman continued, “Within emerging markets, Latin America remains a critical growth region for Amdocs. Our strategy to focus on securing the large carriers of the region, including América Móvil, Telefónica and TIM, is resulting in new customer wins and increased market penetration. We are delighted to announce that Claro Chile, a wholly owned entity of América Móvil, has selected Amdocs to consolidate its business and operational support systems (BSS/OSS). Similarly, we recently announced that Amdocs was selected by Telefónica Argentina to implement a transformation program, marking our first project with the Telefónica group in Latin America.”

Gelman concluded, “This was another quarter of solid execution that comes on the heels of our strong competitive position and focus. Combined with the strict control of our operating margins, we are comfortable that we can meet our fiscal 2013 guidance and provide an attractive total return to our shareholders.”

Financial Discussion of First Fiscal Quarter Results

Free cash flow was $115 million for the quarter, comprised of cash flow from operations of $145 million less $30 million in net capital expenditures and other.

Twelve-month backlog, which includes anticipated revenue related to contracts, estimated revenue from managed services contracts, letters of intent, maintenance and estimated on-going support activities, was $2.8 billion at the end of the first quarter of fiscal 2013.

Financial Outlook

Amdocs expects that revenue for the second quarter of fiscal 2013 will be approximately $820-$850 million. Diluted earnings per share on a non-GAAP basis for the second fiscal quarter are expected to be $0.69-$0.75, excluding amortization of purchased intangible assets and other acquisition-related costs and approximately $0.05-$0.06 per share of equity-based compensation expense, net of related tax effects. Amdocs estimates GAAP diluted earnings per share for the second fiscal quarter will be $0.58-$0.66.

Quarterly Cash Dividend Program

On January 30, 2013, the Board approved the next quarterly cash dividend payment and set March 28, 2013 as the record date for determining the shareholders entitled to receive the dividend, which is payable on April 19, 2013.

Conference Call Details

Amdocs will host a conference call on January 30, 2013 at 5:00 p.m. Eastern Time to discuss the Company's first fiscal quarter results. The call will be carried live on the Internet via the Amdocs website, www.amdocs.com.

Non-GAAP Financial Measures

This release includes non-GAAP diluted earnings per share and other non-GAAP financial measures, including free cash flow, non-GAAP cost of service, non-GAAP research and development, non-GAAP selling, general and administrative, non-GAAP operating income, non-GAAP operating margin, non-GAAP income taxes, non-GAAP net income, and non-GAAP diluted earnings per share. These non-GAAP measures exclude the following items:

• amortization of purchased intangible assets and other acquisition related costs;

• equity-based compensation expense; and

• tax effects related to the above.

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, non-GAAP cost of service, non-GAAP research and development, non-GAAP selling, general and administrative, non-GAAP operating income, non-GAAP operating margin, non-GAAP income taxes, non-GAAP net income, and non-GAAP diluted earnings per share 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, equity-based compensation expense 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 service, research and development, selling, general and administrative, operating income, interest and other expense, 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. Please refer to the Reconciliation of Selected Financial Metrics from GAAP to Non-GAAP tables below.
