PRESS RELEASE

Amdocs Limited Reports Quarterly Revenue of $809 Million, Up 0.9% YoY

Raises Expected FY2012 non-GAAP EPS growth to 14-16% YoY from 12-14%

Key recent highlights:

• Third fiscal quarter revenue of $809 million, compared to the $805-$825 million guidance range. Foreign currency movements negatively affected revenue by approximately $5 million sequentially relative to the second fiscal quarter of 2012

• Third fiscal quarter non-GAAP operating income of $134 million; non-GAAP operating margin of 16.6%; GAAP operating income of $110 million

• Third fiscal quarter diluted non-GAAP EPS of $0.70, compared to the $0.64-$0.70 guidance range, excluding amortization of purchased intangible assets and other acquisition related costs and equity-based compensation expense, net of related tax effects

• Diluted GAAP EPS of $0.59 for the third fiscal quarter, compared to the $0.52-$0.60 guidance range

• Free cash flow of $108 million for the third fiscal quarter

• Twelve-month backlog of $2.76 billion at the end of the third fiscal quarter, up $35 million from the end of the second fiscal quarter of 2012

• Repurchased $122 million of ordinary shares during the third fiscal quarter

• Shareholders approved institution of $0.13 per share quarterly cash dividend program, to commence in October 2012

• Fourth quarter fiscal 2012 guidance: Expected revenue of approximately $815-$835 million and diluted non-GAAP EPS of $0.66-$0.72, 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. Diluted GAAP EPS is expected to be approximately $0.54-$0.62

• Revised fiscal year 2012 guidance: 14-16% non-GAAP EPS growth expected in fiscal 2012, raised from previous expectation of 12-14%. Expected revenue growth of 3-3.5% on a constant currency basis, compared to 3-4% previously. Expected reported revenue growth of 2-2.5% includes the effects of higher than anticipated negative foreign currency fluctuations

ST. LOUIS – August 1, 2012 – Amdocs Limited (NYSE: DOX) today reported that for its third fiscal quarter ended June 30, 2012, revenue was $808.8 million, flat from the second fiscal quarter of 2012 and up 0.9% as compared to last year’s third fiscal quarter. Net income on a non-GAAP basis was $118.4 million, or $0.70 per diluted share, compared to non-GAAP net income of $113.3 million, or $0.61 per diluted share, in the third quarter of fiscal 2011. Non-GAAP net income excludes amortization of purchased intangible assets and other acquisition related costs and equity-based compensation expenses of $19.6 million, net of related tax effects, in the third quarter of fiscal 2012 and excludes such amortization and other acquisition related costs and equity-based compensation expenses of $21.5 million, net of related tax effects, in the third quarter of fiscal 2011. The Company’s GAAP net income for the third quarter of fiscal 2012 was $98.7 million, or $0.59 per diluted share, compared to GAAP net income of $91.8 million, or $0.50 per diluted share, in the prior year’s third fiscal quarter.

“Demonstrating our confidence in the future success of Amdocs and our commitment to delivering a compelling total return to our shareholders, we continued to execute on our share repurchase plan during the third fiscal quarter and will initiate our first quarterly dividend in the coming months. Additionally, we have increased our non-GAAP earnings per-share guidance to 14-16% growth for the full fiscal year of 2012 from 12-14% previously. This guidance captures operating performance consistent with our prior expectations and the benefit of share repurchase activity completed to date,” said Eli Gelman, chief executive officer of Amdocs Management Limited.

Gelman continued, “Our third fiscal quarter results reflect on-going momentum in the emerging markets and managed services, steady business activity in Europe, tempered spending in North America, and greater currency headwinds. Overall, this led to revenue performance roughly in-line with the midpoint of our expectations, excluding the impact of currency fluctuations. In the emerging markets, we continue to see solid momentum across Southeast Asia and Latin America with both new and existing customers. In Latin America, we signed our first managed services engagement. In Europe, we gained some additional traction in managed services during the third quarter. North American results were consistent with our expectations and reflect stable activity with AT&T compared to the previous quarter.”

Gelman concluded, “During the quarter, we signed several key strategic wins. In our broadband, cable and satellite group, we extended our long-term agreement with DIRECTV, the largest satellite company in North America, for an additional 5 years and expanded the scope of our activities with this key customer. We won additional business in the North American pre-paid wireless market which is a growing segment for communications service providers. In the emerging markets, we announced an agreement with TIM Brasil that marks our first BSS and OSS managed services win in Latin America as well as our first ever OSS managed services agreement. We have built a solid relationship with TIM Brasil over the years, including serving its wireless, wireline and, most recently, residential broadband operations, which are now all captured under this managed services engagement. Additionally, in Europe we won an important new managed services deal with a large wireless service provider during the third quarter.”

Financial Discussion of Third Fiscal Quarter Results

Free cash flow was $108 million for the quarter, comprised of cash flow from operations of $138 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 $2.76 billion at the end of the third quarter of fiscal 2012, up $35 million from the end of the second fiscal quarter of 2012.

Financial Outlook

Amdocs expects that revenue for the fourth quarter of fiscal 2012 will be approximately $815-$835 million. Diluted earnings per share on a non-GAAP basis for the fourth fiscal quarter are expected to be $0.66-$0.72, 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 fourth fiscal quarter will be $0.54-$0.62.

Quarterly Cash Dividend Program

On July 31, 2012, at a special shareholders meeting, the Company’s shareholders approved the institution of a quarterly cash dividend program at the quarterly rate of $0.13 per share. On August 1, 2012, the Board approved the first dividend payment and set September 30, 2012 as the record date for determining the shareholders entitled to receive the dividend, which is payable on October 19, 2012.

Conference Call Details

Amdocs will host a conference call on August 1, 2012 at 5:00 p.m. Eastern Time to discuss the Company’s third fiscal quarter results and its business outlook. 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 interest and other expense, net, non-GAAP income taxes, non-GAAP net income, and non-GAAP earnings per share growth. These non-GAAP measures exclude the following items:

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

• gain on sale of investment;

• 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 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, gain on sale of investment, 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.
