EXHIBIT 99.1 FOR IMMEDIATE RELEASE CONTACT: Jim Bauer Investor Relations (678) 473-2647 jim.bauer@arrisi.com ARRIS REVISES FIRST QUARTER 2003 GUIDANCE DUE TO MANUFACTURING AND WEATHER DELAYS ANNOUNCES CONFERENCE CALL DETAILS DULUTH, GA. (MARCH 27, 2003) ARRIS (NASDAQ:ARRS) today provided revised guidance for the ranges of first quarter 2003 revenue and earnings per share. Based upon the most recent external factors discussed below the Company now expects revenue in the range of $90 million to $100 million and earnings per share in the range of $0.02 to $0.08 per share. Guidance is given in terms of GAAP net income per share pursuant to recent SEC pronouncements as opposed to cash earnings. Cash earnings would add amortization of approximately $8.7 million. The revised earnings guidance includes the impact of the previously announced purchase of the Nortel Networks Membership interest at a net discount of $28.5 million and the previously announced write off of decommissioned customer relations software of $2.3 million. Cash earnings per share excluding the items discussed above are expected to be in the range of $(0.13) to $(0.19) per share. "As we approach the end of the quarter, it has become apparent that a combination of recent external factors will push substantial revenues expected in the current quarter from both our Broadband and Supplies & Services product groups into the June quarter," said Larry Margolis, ARRIS EVP & CFO. "Although we may have been able to absorb the impact of some factors, the combined effects cause us now to realize that revenues will fall short of the previous guidance range. A number of factors are contributing to this anticipated shortfall. First, in our Broadband product group, anticipated shipments will be delayed due to recent manufacturing and component availability issues. Although these problems have now been corrected, this disruption has caused as much as $20 million of anticipated shipments to be delayed into the second quarter. "In addition," continued Margolis, "in our Supplies & Services group, the record snow storm in Denver last week not only interfered with normal customer ordering and our order entry processes due to the inability of employees to get to work, but also damaged the roof of our TeleWire Supply headquarters facility and caused a gas leak in the building. These problems forced the evacuation and temporary closure of the Denver TeleWire Supply headquarters facility late last week. Although the facility has now been reopened, order entry and shipments were seriously disrupted at a critical point in time for the first quarter and sales and customer orders which would normally have occurred in the first quarter have been delayed. Weather conditions earlier in the quarter in the northeastern United States also caused a disruption and delay that affected sales for the quarter. These combined weather related issues are estimated to have a $5 million adverse impact on first quarter revenues. In addition, unforeseen order processing delays at one of our largest customers will push an additional estimated $5 million of orders anticipated for the first quarter into the June quarter. We expect most of the delayed shipments described above to be shipped in the second quarter. Finally, we had a backlog of approximately $6 million for Cabovisao, which we are not shipping due to the previously disclosed uncertainty concerning their financing status," concluded Margolis. "Had these supply and weather problems not occurred so late in the quarter, we believe we would have recovered sufficiently to come within our originally announced guidance range, albeit at the lower end," said Bob Stanzione, Arris President and CEO. "Our high-speed data, cable telephony and infrastructure products continue to generate significant customer demand and; therefore, we remain cautiously optimistic concerning the balance of the year. ARRIS will formally announce first quarter 2003 results on April 23, 2003 and will provide second quarter guidance at that time which we anticipate will be above current market consensus revenue estimates." ARRIS has scheduled a conference call to discuss its revised guidance at 8:30am EDT on Friday March 28, 2003.
