Press Release

MICREL REPORTS THIRD QUARTER FINANCIAL RESULTS

·   GAAP earnings $0.12 per diluted share

·   Board of Directors declares quarterly dividend of $0.035 per common share

San Jose, CA, October 27, 2008 — Micrel, Incorporated (Nasdaq NM: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today announced financial results for the third quarter ending September 30, 2008.

Third quarter revenues of $67.5 million up by $2.3 million, or 3%, from $65.2 million compared to the same quarter in the prior year.  Third quarter revenues decreased by $3.1 million, or 4%, from $70.6 million in the second quarter. The sequential decrease in revenues was a result of a reduction in overall demand from customers during the last two weeks of the quarter, as the financial crisis in the United States began to impact the semiconductor industry, causing several of the Company’s customers to reduce orders and conserve cash. The order decrease was abrupt and substantial.  Notwithstanding this order decrease, resales of the Company’s products from global sell-through distributors remained strong throughout the quarter and represented an all-time record for the Company.

Third quarter 2008 GAAP net income increased to $8.5 million, or $0.12 per diluted share.  This compares with second quarter 2008 GAAP net income of $7.2 million, or $0.10 per diluted share, and GAAP net income of $9.4 million or $0.12 per diluted share compared to the same quarter in the prior year.  Third quarter 2008 non-GAAP net income was $9.5 million or $0.13 per diluted share.  A reconciliation of the GAAP net income to non-GAAP net income is provided in the financial tables of this press release.  Non-GAAP results exclude the impact of stock-based compensation expense, other operating income and expense items, proxy contest expenses, restructuring charges and credits, other income related to litigation settlements and their related tax effects.

“Micrel’s third quarter sales were significantly impacted by the slowing global economy,” stated Ray Zinn, president and CEO of Micrel.  “Going into the third quarter, we predicted that the September turns-fill level was key to achieving our revenue guidance and unfortunately, customer demand dropped significantly in the last two weeks of the quarter.  However, I was quite pleased with our operating execution and expense management.  During the quarter, the Company was able to successfully reduce operating expenses.  This resulted in Micrel being able to hit its earning expectations even on lower revenue. In addition, Micrel continues to generate strong cash flow from operations, and we have maintained our quarterly dividend payment and our stock repurchase program to the benefit of all shareholders.”

Outlook

Commenting on Micrel’s business outlook, Mr. Zinn said, “The financial crisis impacting the world economy has caused our customers to restrict their ordering patterns and only place orders to satisfy short term demand.  During the third quarter, total bookings were less than revenues as our distributors implemented actions to decrease inventory levels and conserve cash as a result of the economic slowdown.  Visibility into customer demand continues to be limited due to short order lead times.  The Company is heavily dependent on both a steady, robust sell through from its distributors and from OEMs with approximately forty three percent turns-fill orders.”

For the fourth quarter of 2008, the Company estimates revenues will decline by between 7% to 13% on a sequential basis.  The Company estimates that GAAP earnings per diluted share will be approximately $0.08 to $0.11.

Zinn concluded, “The outlook for the fourth quarter 2008 remains relatively uncertain due to the turbulent worldwide financial crisis and its impact on demand for goods and services.  As I commented last quarter, Micrel has been heavily focused on reducing operating costs as we moved into the second half of the year, while maintaining our commitment to produce new, high-performance products at a rapid rate.  We believe this will position the Company to grow faster than the market over time.  The cost cutting measures we implemented earlier in the year coupled with additional actions planned in the fourth quarter will help the Company remain profitable during these difficult times.”

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 revenues and cost of revenues related to, stock-based compensation expense, other operating income and expense items, proxy contest expenses, restructuring charges or credits, other income related to litigation settlements and their respective 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.
