Item 2.02. Results of Operations and Financial Condition

In preparing the consolidated financial statements of Micrel, Incorporated (the “Company”) for the year ended December 31, 2012, management identified several income tax provision and income tax balance sheet classification errors that impacted the Company's previously filed consolidated financial statements.

The Company evaluated the materiality of these errors on the prior periods' financial statements in accordance with ASC 250 (SEC's Staff Accounting Bulletin No. 99, Materiality) and concluded that they did not, individually or in the aggregate, result in a material misstatement of the Company's previously filed consolidated financial statements. However, the Company also concluded that the effect of recording all corrections in the fourth quarter and year ended December 31, 2012 would have been material and misleading to the users of the consolidated financial statements.

The Company's unaudited financial results for the three and twelve months ended December 31, 2012, which the Company previously announced in a Current Report on Form 8-K filed with the Securities and Exchange Commission (the “Commission”) on January 31, 2013, and the Company's consolidated financial statements for prior years have been revised in the Company's Annual Report on Form 10-K for the year ended December 31, 2012 (the “Form 10-K”) that the Company filed with the Commission on March 18, 2013. (For additional information, see “Revision of Prior Period Financial Statements” in Note 1 of the Notes to the Consolidated Financial Statements beginning on page 44 of the Form 10-K). The revision had no impact on the Company's total cash flows from operating, investing or financing activities for all the periods affected.

This information is not deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, and is not incorporated by reference into any filing of the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing.
