Intellon Reports Third Quarter Fiscal 2009 Results

Revenue Grows 14% Sequentially to $19.9 Million

Orlando, Fla. – October 22, 2009 — Intellon Corporation (Nasdaq: ITLN), a leading provider of HomePlug^®-compatible integrated circuits (ICs) for home networking, networked entertainment, Ethernet-over-Coax (EoC) and smart grid applications, today reported financial results for the third quarter ended September 30, 2009.

Total revenue for the third quarter of 2009 was $19.9 million, a 14% sequential increase from the second quarter of 2009 and a 1% year-over-year decline from the third quarter of 2008.

Revenue derived from sales of HomePlug-compatible ICs comprised 99% of total revenue for the third quarter of 2009 and totaled $19.7 million, a 14% sequential increase from the second quarter of 2009 and a 1% year-over-year increase from the third quarter of 2008.

Intellon reported gross margins of 50.5% for the third quarter of 2009 compared with 50.4% in the second quarter of 2009 and 40.7% in the year ago quarter.

In accordance with generally accepted accounting principles (GAAP), Intellon reported a net loss of $0.4 million, or $0.01 per share (basic and diluted), primarily due to merger related expenses of approximately $1.8 million, for the third quarter of 2009, compared with net income of $0.3 million, or $0.01 per share (basic and diluted), for the second quarter of 2009, and net income of $0.5 million, or $0.02 per share (basic and diluted), for the third quarter of 2008.

Non-GAAP net income in the third quarter of 2009 was $2.0 million, or $0.06 per share (basic and diluted), compared with non-GAAP net income of $0.9 million, or $0.03 per share (basic and diluted), for the second quarter of 2009, and non-GAAP net income of $0.9 million, or $0.03 per share (basic and diluted), for the third quarter of 2008.

A detailed reconciliation between GAAP and non-GAAP net income (loss) is provided in a table following the condensed consolidated statements of operations.

“Fueled by our global customer base and diversified sales channels, Intellon delivered another strong quarter of operating results,” said Charles E. Harris, Chairman and CEO of Intellon. “Our service provider and Ethernet-over-Coax business grew sequentially by 30% and 25%, respectively, contributing to our 14% sequential revenue growth for the quarter. Our gross margins of 50.5% represented a 980 basis point improvement over the year ago period and our third sequential quarter of gross margins above 50.0%. We also remained disciplined in our financial management, delivering better-than-expected non-GAAP EPS of $0.06 and positive cash flow,” Harris continued.

“On September 8, 2009 Atheros and Intellon announced a definitive agreement for Atheros to acquire Intellon,” Harris added. “The Intellon team is excited about the opportunity to combine its knowledge and expertise in wired networking with Atheros’ leadership in wireless LAN and other network communications,” Harris concluded.
