ARRIS ANNOUNCES PRELIMINARY AND UNAUDITED
FIRST QUARTER 2011 RESULTS

Suwanee, Ga. (April 27, 2011) ARRIS Group, Inc. (NASDAQ:ARRS), today announced preliminary and unaudited financial results for the first quarter 2011.

Revenues in the first quarter 2011 were $267.4 million as compared to first quarter 2010 revenues of $266.7 million and as compared to fourth quarter 2010 revenues of $266.2 million.

Adjusted net income (a non-GAAP measure) in the first quarter 2011 was $0.16 per diluted share, compared to $0.24 per diluted share for the first quarter 2010 and $0.19 per diluted share for the fourth quarter 2010.

GAAP net income in the first quarter 2011 was $0.09 per diluted share, as compared to first quarter 2010 GAAP net income of $0.15 per diluted share and fourth quarter 2010 GAAP net income of $0.09 per diluted share. Significant GAAP items that have been excluded in computing adjusted net income and adjusted net income per diluted share include amortization of intangible assets, equity compensation, non-cash interest expense, restructuring charges, and certain discrete tax items. A reconciliation of adjusted net income to GAAP net income per share is attached to this release and also can be found on the Company’s website (www.arrisi.com).

Gross margin for the first quarter 2011 was 36.3%, which compares to the first quarter 2010 gross margin of 42.2% and the fourth quarter 2010 gross margin of 36.2%.

The Company ended the first quarter 2011 with $619.6 million of cash, cash equivalents and short-term investments, down in the aggregate by approximately $41.5 million from the end of the first quarter 2010, reflecting approximately $93 million of repurchases of stock and debt retirement in 2010, and down $0.5 million from the end of the fourth quarter 2010. The Company used $3.6 million of cash for operating activities during the first quarter 2011, which compares to $48.2 million generated during the same period in 2010.

Order backlog at the end of the first quarter 2011 was $177.5 million as compared to $195.1 million and $140.4 million at the end of the first quarter 2010

and the fourth quarter 2010, respectively. The Company’s book-to-bill ratio in the first quarter 2011 was 1.14 as compared to the first quarter 2010 of 1.19 and the fourth quarter 2010 of 1.08.

“First quarter financial results came in within our range of guidance,” said Bob Stanzione, ARRIS Chairman & CEO. “I am very pleased with the progress we are making with customers for our new higher density C4 line cards which will be shipping in the second quarter. Additionally, the recent announcement of our first customer for our new IP Home Gateway product is an indicator of our traction in the strategy to expand into the video based products market.”

During the quarter the Company announced a number of new products as well as a resale agreement with Ruckus Wireless which the Company expects will ramp in the second half of 2011. In February, the Company announced that its Whole Home Solution Media Gateway will be offered by Oregon-based MSO BendBroadband throughout its network. The ARRIS Whole Home Solution consists of the ARRIS Media Gateway, a converged multi-services platform that provides integrated multimedia entertainment to the entire home, and ARRIS Media Players connected to each television. Also during the quarter the Company announced that the ARRIS VIPr™ video transcoding platform with Digital Video Broadcasting (DVB) functionality will be available in April. The transition from analog to digital continues to accelerate, expanding the addressable market for DVB-capable devices.

“With respect to the second quarter 2011, we now project that revenues for the Company will be in the range of $260 to $280 million, with adjusted net income per diluted share in the range of $0.16 to $0.20 and GAAP net income per diluted share in the range of $0.06 to $0.10,” said David Potts, ARRIS EVP & CFO. “Our guidance reflects initial sales of our new C4 CMTS line card capacity upgrade which we anticipate will gain momentum in the second half of 2011, but also reflects higher than usual start-up expenditures related to new products.”

ARRIS management will conduct a conference call at 5:00 pm EDT, today, Wednesday, April 27, 2011, to discuss these results in detail. You may participate in this conference call by dialing 888-713-4217 or 617-213-4869 for international calls prior to the start of the call and providing the ARRIS Group, Inc. name, conference pass code 99866058 and Jim Bauer as the moderator.

Forward-looking statements:

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

• growth expectations and business prospects;

• revenues and net income for the second quarter 2011, full year 2011 and beyond;

• start up costs;

• expected sales levels and acceptance of new ARRIS products; and

• the general market outlook and industry trends

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 second quarter 2011 as well as the general outlook for 2011 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;

• ARRIS’ customers operate in a capital intensive consumer based industry, and the current volatility in the capital markets or changes in customer spending may adversely impact their ability or willingness to purchase the products that the Company offers; and

• 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, 2010. In providing forward-looking statements, the Company expressly disclaims any obligation to update publicly or otherwise these statements, whether as a result of new information, future events or otherwise.

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. With respect to amortization of intangibles, the intangibles being amortized relate to our acquisitions. The acquisition costs, restructuring, and other 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. With respect to the convertible debt non-cash interest, ARRIS records non-cash interest expense related to the 2013 convertible debt . Disclosing the non-cash piece provides investors with the information regarding interest that will not be paid out in cash. In the first quarters of 2011 and 2010, income tax expense adjustments were recorded for state valuation allowances and research and development tax credits.

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.
