MICREL REPORTS SECOND QUARTER 2007 FINANCIAL RESULTS

· Second quarter revenues of $65.1 million, up 3% sequentially

· Second quarter net income of $0.11 per diluted share within expectations

· Board of Directors declares quarterly dividend of $0.03 per common share

San Jose, CA, July 25, 2007 — Micrel, Incorporated (Nasdaq NM: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today announced financial results for the second quarter ending June 30, 2007.

Revenues for the second quarter were $65.1 million, a sequential increase of 3% over the $63.1 million recorded in the first quarter, and 7% lower than the $70.2 million posted in the year-ago period. Second quarter net income was $8.6 million, or $0.11 per diluted share. This compares with first quarter 2007 net income of $17.9 million, or $0.23 per diluted share, and net income of $9.0 million, or $0.11 per share, in the year ago period. First quarter 2007 results included a one-time $15.5 million pre-tax gain associated with a legal settlement, equivalent to $0.13 per diluted share, net of income taxes.

“Micrel’s second quarter results were solid and I was pleased with our operating execution,” stated Ray Zinn, president and CEO of Micrel. “Our revenues grew sequentially driven by sales to the high-speed communications end market. The Company released a record number of new products in the second quarter and customer design activity remained strong. Earnings per share were in-line with guidance and during the quarter the Company managed to reduce its inventory to targeted levels without significant impact to gross margin.”

The Company also announced today that Micrel’s Board of Directors has authorized a quarterly dividend payment of $0.03 per share of common stock. The payment will be made on August 22, 2007 to shareholders of record as of August 7, 2007.

Outlook

Order lead times for the Company’s products remain at four to six weeks, but a relatively high proportion of quarterly revenue must still be booked and shipped within the quarter to OEM customers, or resold through the Company’s distributors. The Company estimates third quarter 2007 revenues will increase sequentially by 3% to 6%, and earnings per diluted share will be in a range of $0.12 to $0.13.

Zinn concluded, “We are encouraged by continued strong customer interest in the Company’s new products and the second quarter’s positive book-to-bill ratio. These factors bode well for sustained revenue growth for Micrel as we move into the seasonally stronger second half of the year. While we did not hit the high end of our revenue guidance in the second quarter, we are still confident that our design win momentum is going to yield better than average growth for Micrel over the next twelve months.”
