Press Release

San Jose, CA, October 25, 2012 —Micrel Inc., (Nasdaq:MCRL), a leading global manufacturer of IC solutions for the worldwide high performance linear and power, LAN and timing and communications markets, today announced financial results for the third quarter ended September 30, 2012.

Third quarter revenues totaled $62.9 million, a decrease of $0.8 million, or 1.2%, from $63.7 million in the second quarter of 2012. The decrease in revenues during the third quarter is primarily a result of lower sales of the Company's timing and communications products partially offset by gathering momentum in LAN solutions product sales.

Third quarter 2012 GAAP net income of $4.7 million, or $0.08 per diluted share, compares to second quarter 2012 GAAP net income of $6.0 million, or $0.10 per diluted share, and GAAP net income of $9.2 million, or $0.15 per diluted share in the same period of 2011. Third quarter 2012 non-GAAP net income of $5.8 million, or $0.10 per diluted share, compares to second quarter 2012 non-GAAP net income of $7.3 million, or $0.12 per diluted share, and non-GAAP net income of $10.2 million, or $0.16 per diluted share in the same period of 2011. A reconciliation of the GAAP net income to non-GAAP net income is provided in the financial tables at the end of this press release. Non-GAAP results exclude the impact of stock-based compensation expense and the related tax effects.

Micrel's recent design wins in the data communication segment demonstrate Micrel's ability to develop state-of-the-art energy efficient DC-to-DC convertors. The Company’s SuperSwitcherII™ family of DC-to-DC convertors has been adopted by major data communication OEMs to power demanding high efficiency communication data cards. This is just a sampling of Micrel’s recent successes with recent product introductions. The Company continues to focus its efforts on solving the most challenging problems customers face.

Commenting on the third quarter results, Micrel’s President and CEO Ray Zinn said, “Third quarter revenues of $62.9 million and net income of $0.08 per diluted share were each within our range of expectations for the quarter. Operationally, third quarter gross margin declined sequentially to 52.9% from 55.2% due to lower factory capacity utilization and a mix shift to lower margin consumer-related products. Despite the challenging environment, I am encouraged by the continuing strength of our bookings, which have yielded a book-to-bill ratio above one for the third quarter and solidly above one on a year-to-date basis. In addition, we remain very focused on increasing shareholder value through our stock repurchase program and quarterly dividend payments. This past quarter, Micrel spent $13.7 million to repurchase nearly 1.4 million shares of common stock and we also increased our quarterly dividend 6.25% to $0.0425 per common share to shareholders of record as of November 9, 2012. And finally, as part of keeping pace with the dynamics of an ever changing market landscape, we recently renamed several of our product groups to more accurately reflect current technology trends and customer needs. Analog is now called Micrel’s high performance linear and power group; Ethernet is LAN solutions and Micrel’s High Bandwidth product line is now the timing and communications product group."

Mr. Zinn continued, “While we are experiencing a challenging overall macroeconomic environment, we are encouraged with the on-going strength of our products for the wireless handset and communications end markets. We are also gaining traction with our new Super SwitcherII™ products. Overall, I am pleased with our ability to control expenses, and at the same time, create best-in-class products. With this as our foundation, I am confident that as the economy improves, we will see resurgence in Micrel’s revenue growth.

Looking ahead to the fourth quarter, based on historical trends and our current visibility, we expect that fourth quarter 2012 revenues will be flat to down 6% on a sequential basis. Gross profit margin is expected to be in the range of approximately 51.0% to 53.0% based on our anticipated product mix and factory utilization rate. In addition, we expect that fourth quarter 2012 GAAP net income will be approximately $0.04 to $0.07 per diluted share,” Mr. Zinn concluded.

The Company announced today that Micrel’s Board of Directors has authorized a quarterly cash dividend of $0.0425 per share of common stock. The payment of this dividend will be made on November 23, 2012 to shareholders of record as of November 9, 2012.

Share Repurchase Plan
In the third quarter of 2012, the Company repurchased nearly 1.4 million shares for a total of $13.7 million. As of September 30, 2012, up to approximately $25.3 million of additional repurchases of the Company’s stock remain under the stock repurchase plan authorized by the Board of Directors. The authorization will stay in effect until the aggregate authorized amount is expended or the authorization is modified by the Board of Directors. Going forward, the timing and amount of any repurchase of shares will continue to be determined by the Company’s management, based on its evaluation of market conditions, cash on hand and other factors. The repurchases may occur from time to time in the open market or in privately negotiated transactions; provided that the repurchases are made in accordance with the terms of Rule 10b-18 under the Securities Exchange Act of 1934, as amended. Enhancing shareholder value continues through Micrel’s stock repurchase program and quarterly dividend payments. Since 2001, the Company has spent $424 million repurchasing Micrel common stock and paid out approximately $51 million dollars in dividends to shareholders of record since the dividend program began in 2007. During the last three quarters, free cash flow was approximately 11% of revenue. The share repurchases, combined with third quarter dividend payments, amounted to approximately 3.7 times free cash flow.

Non-GAAP Reporting
The Company presents non-GAAP financial measures only because investors and financial analysts use non-GAAP results in their analysis of historical results and projections of the Company’s future operating results. The Company’s management uses non-GAAP measures on a limited basis, primarily for employee performance-based compensation. In order to facilitate the computation of non-GAAP results for the financial analyst community and investors, the Company makes reference to non-GAAP net income and earnings per share. These non-GAAP results exclude the impact of stock-based compensation expense and the related tax effects. Micrel references those results to allow a better comparison of results in the current period to those in prior periods and to provide insight to the Company’s on-going operating performance after exclusion of these items. The Company has reconciled such non-GAAP results to the most directly comparable GAAP financial measures in the financial tables at the end of this press release.

Reference to these non-GAAP results should be considered in addition to results that are prepared under current accounting standards, but should not be considered a substitute for results that are presented in accordance with GAAP. It should also be noted that Micrel’s non-GAAP information may be different from the non-GAAP information provided by other companies.
