Intersil Corporation Updates its Second Quarter 2010 Outlook

Milpitas, CA, May 14, 2010 – Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high performance analog and mixed signal semiconductors, today announced that it has updated its second quarter 2010 financial outlook to account for its recent acquisition of Techwell, Inc. The Techwell acquisition closed on April 27, 2010.

During its annual Investor & Analyst Day today in San Mateo, CA, Intersil will provide the following update to its previously issued second quarter 2010 outlook:

• Revenues are expected to be in the range of $214 million to $222 million
• Research and development expenses are expected to be approximately $47 million
• Selling, general and administrative expenses are expected to be approximately $35 million
• Stock-based compensation expense is expected to be approximately $9.3 million

• One-time acquisition related expenses are expected to be approximately $17 million
• Excluding amortization and one-time acquisition-related expenses, non-GAAP earnings per diluted share are expected to be in the range of $0.22 to $0.25

Intersil management also provided an update on its long-term goal of reaching a billion dollar revenue run rate. Last year's goal of achieving revenues of $250 million during the fourth quarter of 2011 was accelerated by one year, with that sales level now expected during the fourth quarter of 2010.

"We are excited to bring Techwell into the Intersil family, and are discovering an increasing number of engineering and marketing synergies. Because of this acquisition, industrial is now Intersil's largest end market, and is expected to drive stable, profitable growth," said Mr. Bell. "The diversity of our product portfolio continues to increase with more than one new product family per quarter added during the last two years."
