ARRIS ANNOUNCES PRELIMINARY AND UNAUDITED
SECOND QUARTER 2008 RESULTS

Suwanee, Ga. (July 30, 2008) ARRIS Group, Inc. (NASDAQ:ARRS), a global technology leader in advanced cable telephony and broadband access equipment, next generation high-speed data and video applications, and operations software solutions, today announced preliminary and unaudited financial results for the second quarter 2008.

Second quarter 2008 revenues of $281.1 million increased $7.6 million, or 2.8%, as compared to first quarter revenues of $273.5 million. Second quarter and first half 2008 revenues increased $28.4 million, or 11.2%, and $66.6 million, or 13.6%, respectively, as compared to the same periods in 2007, primarily due to the C-COR acquisition. Second quarter 2008 gross margin was $92.9 million, or 33.0%, as compared to $85.2, or 31.2%, in the first quarter 2008 and $72.4 million, or 28.6%, in the second quarter 2007. Order backlog increased to $206.0 million at the end of the second quarter as compared to $147.0 million at the end of the first quarter. Book-to-bill ratio in the second quarter was 1.21.

GAAP net income in the second quarter 2008 was $0.08 per diluted share, as compared to $0.21 per diluted share for the second quarter 2007. Adjusted (non-GAAP) net income in the second quarter 2008 was $0.15 per diluted share, as compared to $0.22 per diluted share for the second quarter 2007. Items excluded from the computed adjusted (non-GAAP) net income include: amortization of intangibles, certain acquisition gains and expenses, certain tax benefits and costs, equity compensation expense, and adjustments to restructuring accruals. A reconciliation of GAAP to adjusted (non-GAAP) earnings per share is attached to this release and also can be found on the Company’s website (www.arrisi.com).

The Company ended the second quarter 2008 with $297.8 million of cash and short-term investments, which compares to $293.0 million at the end of the first quarter 2008. The Company generated $10.4 million of cash from operating activities in the second quarter 2008.

“I am very pleased that despite the challenging economic climate, we can report that sales, earnings and margins are up quarter over quarter and we look for continuing strength in the second half of 2008 as we enter the third quarter with a healthy backlog,” said Bob Stanzione, ARRIS Chairman & CEO. “The demand for ARRIS products remains strong as our customers see increasing competition and new service demands in their markets. International opportunities continue to unfold as evidenced by our recent CMTS agreement last month with the largest cable operator in Germany and new opportunities in Canada and Mexico. We are well positioned to take advantage of customer and end user demands for high speed data services, VoIP, on-demand video, ad insertion, OSS solutions and network upgrades to accommodate increased high definition channel offerings and streaming video.”

“We enter the second half of 2008 with a strong order book and an improving margin profile,” said David Potts, ARRIS EVP & CFO. “I am also very pleased with the solid progress that we have made with the integration of C-COR and the progress that we have made towards the overall financial goals that we outlined at our Investor Conference in March. At this point, we project that revenues for the Company in the third quarter 2008 will be in the range of $288 to $308 million with GAAP net income per diluted share in the range of $0.13 to $0.18 and adjusted (non-GAAP) net income per diluted share, in the range of $0.19 to $0.24.

Forward-looking statements:

Statements made in this press release, including those related to:

• third quarter and 2008 revenues, gross margin, and net income;

• full year 2008 outlook, and

• the general market outlook;

are forward-looking statements. These statements involve risks and uncertainties that may cause actual results to differ materially from those set forth in these statements. Among other things,

• projected results for the third quarter as well as the general outlook for 2008 and beyond are based on preliminary estimates, assumptions and projections that management believes to be reasonable at this time, but are beyond management’s control;

• because the market in which ARRIS operates is volatile, actions taken and contemplated may not achieve the desired impact relative to changing market conditions and the success of these strategies will be dependent on the effective implementation of those plans while minimizing organizational disruption.

In addition to the factors set forth elsewhere in this release, other factors that could cause results to differ from current expectations include: the uncertain current economic climate and its impact on our customers’ plans and access to capital; the impact of rapidly changing technologies; the impact of competition on product development and pricing; the ability of ARRIS to react to changes in general industry and market conditions including regulatory developments; rights to intellectual property, market trends and the adoption of industry standards; and consolidations within the telecommunications industry of both the customer and supplier base. These factors are not intended to be an all-encompassing list of risks and uncertainties that may affect the Company’s business. Additional information regarding these and other factors can be found in ARRIS’ reports filed with the Securities and Exchange Commission, including its Form 10-K for the year ended December 31, 2007 and its Form 10-Q for the quarter ended March 31, 2008.

With respect to stock compensation expense, ARRIS records non-cash compensation expense related to grants of options and restricted stock. Depending upon the size, timing and the terms of the grants, this non-cash compensation expense may vary significantly. In prior periods, ARRIS recognized a gain in Q1 of 2007 associated with previously written off receivables. With respect to amortization of intangibles, the intangibles being amortized relate to our recent acquisition of C-COR. The restructuring charge adjustments reflect items that, although they or similar items might recur, are of a nature and magnitude that identifying them separately provides investors with a greater ability to project ARRIS’ future performance. In the second quarter of 2007, ARRIS realized a gain before tax of $1.3 million on its deferred compensation asset that had been previously recorded as an unrealized gain on the balance sheet. During the first quarter of 2007, ARRIS announced that it entered into a transaction agreement with TANDBERG Television ASA, in which ARRIS was to buy all the outstanding shares of TANDBERG. ARRIS was subsequently outbid by another buyer and the transaction agreement was terminated during the first quarter 2007. ARRIS recorded gains, net before tax, of $22.8 million related to the termination of the transaction (termination fee, foreign exchange gains, and expenses). The net termination fee resulted in a capital gain which provided greater access to prior tax capital losses that had previously been viewed as more likely than not unrealizable. As a result, net income tax valuation allowances totaling $3.2 million were reversed in the first quarter 2007. During the first quarter of 2008, ARRIS recorded incremental costs of $0.4 million as a result of the C-COR integration.

In assessing operating performance and preparing budgets and forecasts, ARRIS’ management considers performance after making these adjustments and believes that providing investors with the same information provides greater transparency and insight into management’s analysis. ARRIS expects to continue providing similar information in the future with schedules reconciling the differences between GAAP and non-GAAP financial measures.
