1. SIGNIFICANT ACCOUNTING POLICIES

Interim Financial Information - The accompanying condensed consolidated financial statements of Micrel, Incorporated and its wholly-owned subsidiaries (together “Micrel” or the “Company”) as of June 30, 2013 and for the three and six months ended June 30, 2013 and 2012 are unaudited. In the opinion of management, the condensed consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) that management considers necessary for a fair statement of its financial position, operating results, comprehensive income and cash flows for the interim periods presented. Operating results and cash flows for interim periods are not necessarily indicative of results for the entire year. The Condensed Consolidated Balance Sheet as of December 31, 2012, was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted (“GAAP”) in the United States of America. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. These financial statements should also be read in conjunction with the Company’s critical accounting policies included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 and those included in this Form 10-Q below.

Net Income Per Share- Basic net income per share is computed by dividing net income attributable to Micrel, Incorporated shareholders by the number of weighted-average common shares outstanding. Diluted net income per share reflects potential dilution from outstanding stock options using the treasury stock method and restricted stock units. Reconciliation of weighted-average shares used in computing basic and diluted net income per share attributable to Micrel, Incorporated shareholders is as follows (in thousands):

	Three Months Ended		Six Months Ended
	June 30,		June 30,
	2013	2012	2013	2012
Weighted average common shares outstanding	58,303	60,217	58,287	60,533
Dilutive effect of stock options and restricted stock units	704	620	734	686
Shares used in computing diluted net income per share	59,007	60,837	59,021	61,219

For the three and six months ended June 30, 2013, 5.5 million and 5.4 million shares underlying stock options, respectively, have been excluded from the weighted-average number of common shares outstanding for the diluted net income per share computations as they were anti-dilutive. For the three and six months June 30, 2012, 5.5 million and 5.3 million shares underlying stock options, respectively, have been excluded from the weighted-average number of common shares outstanding for the diluted net income per share computations as they were anti-dilutive.

2. RECENTLY ISSUED ACCOUNTING STANDARDS

Effective January 1, 2013, the Company adopted the new guidance to improve the reporting of reclassifications out of accumulated other comprehensive income. The guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under GAAP to be reclassified in its entirety to net income. For other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide addition detail about those amounts. The adoption did not have a material impact on the Company's consolidated financial condition or results of operations.

Effective January 1, 2013, the Company adopted the new guidance to reduce the complexity and cost of performing an evaluation of impairment of indefinite-lived intangible assets other than goodwill. Under the new guidance, an entity is permitted to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. The adoption did not have a material impact on the Company's consolidated financial condition or results of operations.

In March 2013, the Financial Accounting Standards Board ("FASB") issued an accounting standards update on foreign currency matters that provides additional guidance with respect to the reclassification into income of the cumulative translation adjustment (CTA) recorded in accumulated other comprehensive income associated with a parent company's ownership interest in a foreign entity. The standard differentiates between transactions occurring within a foreign entity and transactions/events affecting an investment in a foreign entity. For transactions within a foreign entity, the full CTA associated with the foreign entity would be reclassified into income only when the sale of a subsidiary or group of net assets within the foreign entity represents the substantially complete liquidation of that foreign entity. For transactions/events affecting an investment in a foreign entity (for example, control or ownership of shares in a foreign entity), the full CTA associated with the foreign entity would be reclassified into income only if the parent no longer has a controlling interest in that foreign entity as a result of the transaction/event. In addition, acquisitions of a foreign entity completed in stages will trigger release of the CTA associated with an equity method investment in that entity at the point a controlling interest in the foreign entity is obtained.The Company is required to adopt this standard for its interim and annual periods beginning after December 15, 2013. As of June 30, 2013, the Company has not recorded CTA related to its ownership interests in a foreign entity. This standard would impact the Company's consolidated financial condition or results of operations only in the instance the Company records CTA and an event or transaction described above occurs.

In July 2013, the FASB issued an accounting standards update on presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The standard requires that unrecognized tax benefits should be presented as a reduction to deferred tax assets for net operating loss carry forwards, a similar tax loss or a tax credit carry forward (Carryforward), if such Carryforward is required or expected to settle the additional income taxes in the event the uncertain tax position is disallowed. The standard also requires in situations that a Carryforward cannot be used or the deferred tax asset is not intended to be used for such purpose, the unrecognized tax benefit should be recorded as a liability and should not offset deferred tax assets. The Company is required to adopt this standard for its interim and annual periods beginning after December 15, 2013. The Company is currently evaluating the impact of adopting this guidance, but does not expect it to have a material impact on the Company's consolidated financial condition or results of operations.

3. SHARE-BASED COMPENSATION

Share-based compensation is measured at the grant date based on the fair value of the award and is recognized over the employee’s requisite service period.The following table summarizes total share-based compensation expense included in the Condensed Consolidated Statement of Operations (in thousands):

	Three Months Ended						Six Months Ended

During the three months ended June 30, 2013 and 2012, the Company granted 166,100 and 645,400 stock options, respectively, at weighted average fair values of $3.04 and $2.92 per share, respectively. For the six months ended June 30, 2013 and 2012, the Company granted 344,500 and 783,820 stock options, respectively, at weighted average fair values of $2.97 and $2.95 per share, respectively. The fair value of the Company’s stock options granted under the Company’s option plans was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

The Company also grants Restricted Stock Units (“RSUs”) to its employees. In the three months ended June 30, 2013 and 2012, the Company granted 115,068 and 211,086 RSUs, respectively, at weighted average fair values of $9.56 and $9.73, respectively. During the six months ended June 30, 2013 and 2012, the Company granted 227,400 and 256,086 RSUs, respectively, at weighted average fair values of $9.81 and $9.76, respectively.

As of June 30, 2013, there was $14.7 million of total unrecognized share-based compensation related to non-vested awards which is expected to be recognized over a weighted-average period of 2.9 years. Total share-based compensation capitalized as part of inventory as of June 30, 2013 and December 31, 2012 was $168,000 and $139,000, respectively.

Under the Company’s Employee Stock Purchase Plan (“ESPP”), eligible employees are permitted to have salary withholdings to purchase shares of Common Stock at a price equal to 95% of the market value of the stock at the end of each three-month offer period, subject to an annual limitation. The ESPP is considered non-compensatory per current share-based compensation accounting guidelines.

4. INVESTMENTS

Short-term investments represent the investment of cash in instruments that are available to fund current operations with remaining maturities of greater than three months on the date of purchase. Short-term investments as of June 30, 2013 primarily consisted of corporate debt securities, commercial paper and liquid municipal debt securities with maturities ranging from less than one month to less than two years and were classified as available-for-sale securities. Long-term investments as of June 30, 2013 consisted of auction rate notes secured by student loans and were classified as available-for-sale securities. Available-for-sale securities are stated at market value with unrealized gains and losses included in accumulated other comprehensive income. Unrealized credit losses are charged against income when a decline in the fair market value of an individual security is determined to be other than temporary. Realized gains and losses on investments are included in other income or expense. A summary of the Company’s short-term investments at June 30, 2013 and December 31, 2012 is as follows (in thousands):

	As of June 30, 2013									As of December 31, 2012

The Company recorded a cumulative temporary loss of $25,000 net of tax ($38,000 pre-tax) for its short-term securities as of June 30, 2013 to accumulated other comprehensive income, a component of shareholders' equity. The change in the fair value of these securities is recorded to unrealized gains (losses) on investments in the condensed consolidated statements of comprehensive income. As of June 30, 2013, none of the Company’s short-term investments was in a continuous unrealized loss position for more than twelve months.

A summary of the Company’s long-term investments at June 30, 2013 and December 31, 2012 is as follows (in thousands):

As of June 30, 2013, the Company had auction rate notes with an amortized cost of $4.7 million and a fair value of $4.2 million. Auction rate notes are securities that are structured with short-term interest rate reset dates of generally less than ninety days, but with contractual maturities that can be in excess of ten years. At the end of each reset period, which occurs every seven or twenty eight days for the securities held by the Company, investors can sell or continue to hold the securities at par. As a result of sell orders exceeding buy orders, auctions for the student loan-backed notes held by the Company have failed and not resumed as of June 30, 2013. The principal associated with failed auctions will not be accessible until a successful auction occurs, a buyer is found outside of the auction process, the issuers redeem the securities, the issuers repay principal over time from cash flows prior to final maturity or final payments come due according to contractual maturities ranging from 19 to 34 years. As a result, the Company has classified all auction rate notes as long-term investments as of June 30, 2013 and December 31, 2012, and the auction rate notes have been in a continuous unrecognized loss position since 2008 when auctions began to fail. As a result of failed auctions, the notes bear interest at a predetermined maximum rate based on the credit rating of notes as determined by one or more nationally recognized statistical rating organizations. For the auction rate notes held by the Company as of June 30, 2013 and December 31, 2012, the maximum interest rate is generally one month LIBOR plus 1.5% or 2.5% based on the notes' rating as of that date. The Company has collected all interest payable on all of its auction-rate securities when due and expects to continue to do so in the future. The Company has not recognized an other than temporary impairment loss on the auction rate notes because it expects to recover the full amortized cost basis of the securities, i.e., a credit loss has not occurred, and it has the ability and intent to hold the investments until such time.

To determine the fair value of financial instruments, the Company uses a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

• Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company's short-term investments are classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or other significant observable inputs.

The types of instruments valued based on unobservable inputs include the auction rate securities held by the Company. Such instruments are classified within Level 3 of the fair value hierarchy and are recorded under long-term investments in the condensed consolidated balance sheets.The Company estimated the fair value of these auction rate securities using a discounted cash flow model incorporating assumptions that market participants would use in their estimates of fair value. Some of these assumptions include estimates for interest rates, timing and amount of cash flows and expected holding periods of the auction rate securities.

Financial assets measured at fair value on a recurring basis as of June 30, 2013 were as follows (in thousands):

	Quoted Prices in Active Markets for Identical Assets Level 1		Significant Other Observable Inputs Level 2		Significant Unobservable Inputs Level 3		Total

There were no significant transfers between Level 1 and Level 2 of the fair value hierarchy.

The Company has used a combination of discounted cash flow models and observable transactions for similar securities to determine the estimated fair value of its investment in auction rate notes as of June 30, 2013 and December 31, 2012. The assumptions used in preparing the discounted cash flow model include estimates for interest rates, estimates for discount rates using yields of comparable traded instruments adjusted for illiquidity and other risk factors, amount of cash flows and expected holding periods of the auction rate notes. Based on this assessment of fair value, as of June 30, 2013, the Company determined there was a cumulative decline in the fair value of its auction rate notes and recorded a $315,000 net of tax ($484,000 pre-tax) temporary impairment of these securities to accumulated other comprehensive income, a component of shareholders’ equity. The change in the fair value of these securities is recorded to unrealized gains (losses) on investments in the condensed consolidated statements of comprehensive income.

For the six months ended June 30, 2013, the changes in the Company’s Level 3 securities (consisting of auction rate notes) were as follows (in thousands):

7. GOODWILL AND INTANGIBLE ASSETS

Goodwill

Goodwill represents the excess of the purchase price paid over the fair value of tangible and identifiable intangible net assets acquired in a business combination. On April 2, 2012, the Company acquired PhaseLink and recorded $6.1 million of goodwill as the purchase price exceeded the fair value allocated to net tangible assets and identifiable intangible assets. The goodwill has been assigned to the timing and communications reporting unit and will be reviewed annually in October or whenever events or circumstances occur which indicate that goodwill might be impaired.

The Company’s annual goodwill impairment assessment will include first performing a qualitative assessment. As part of this assessment, the Company will consider whether it is not more likely than not that the fair value is less than the carrying value of the reporting unit. If, after assessing the qualitative factors, a company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test is unnecessary. However, if a company concludes otherwise, then it is required to perform the first step of the two-step goodwill impairment test. The first step requires a comparison of the fair value of the Company’s reporting unit to its net book value. If the fair value is greater, then no impairment is deemed to have occurred. If the fair value is less, then the second step must be performed to determine the amount, if any, of actual impairment.

Intangible Assets

The Company evaluates intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable. An asset is considered impaired if its carrying amount exceeds the undiscounted future net cash flow that the asset is expected to generate. The process of evaluating the potential impairment of long-lived intangible assets is highly subjective and requires significant judgment. In estimating the fair value of these assets, the Company makes estimates and judgments about future revenues and cash flows. The Company’s forecasts will be based on assumptions that are consistent with the plans and estimates the Company is using to manage the business. Changes in these estimates could change the Company’s conclusion regarding impairment of the long-lived assets.

9. BORROWING ARRANGEMENTS

Under the terms of an unsecured credit facility with Bank of the West, the Company has a $5.0 million line of credit available for general working capital needs, which includes a $5.0 million letter of credit sub-facility including a $2.0 million foreign exchange sub-facility. In April 2013, an amendment was entered to amend certain terms of the credit agreement including an extension of the expiration date to April 30, 2015 and the deletion of a minimum effective tangible net worth covenant. Interest rates under the amended agreement are based on one of three interest rates, at the Company’s option: (1) a variable alternate base rate plus 1.0%, the alternate base rate being the greater of (x) Bank of the West’s prime rate, (y) the Fed Funds Rate plus 0.5% or (z) daily adjusted one-month LIBOR plus 1.0%; (2) floating one-month LIBOR plus 2.0% or (3) fixed LIBOR for one, two, three or six month periods, plus 2.0%. The agreement includes certain restrictive covenants and, as of June 30, 2013, the Company was in compliance with such covenants.

The Company's borrowing arrangements include a provision for the issuance of commercial or standby letters of credit by the bank on behalf of the Company. As of June 30, 2013, there was $325,000 in letters of credit outstanding. The letters of credit are issued to guarantee payments for the Company's workers compensation program. As of June 30, 2013, the Company had no borrowings under the line of credit.

10. DERIVATIVE FINANCIAL INSTRUMENTS

During the three and six months ended June 30, 2013 and 2012, the Company was not party to any derivative instrument arrangements. At June 30, 2013, there were no derivative instrument contracts outstanding.

11. SIGNIFICANT CUSTOMERS

During the six months ended June 30, 2013, two worldwide distributors accounted for $39.3 million (33%) and $25.8 million (22%) of net revenues, respectively. During the six months ended June 30, 2012, two worldwide distributors and one direct customer accounted for $31.5 million (25%), $20.8 million (17%) and $13.3 million (11%) of net revenues, respectively. These distributors operate globally and regionally to sell Micrel's products to many customers across various end markets.

At June 30, 2013, two worldwide distributors accounted for 39% and 17%, respectively, of total accounts receivable. At December 31, 2012, one worldwide distributor and an Asia-based distributor accounted for 28% and 14%, respectively, of total accounts receivable.

12. SEGMENT REPORTING

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker. The Company has two reportable segments: standard products and other products, which consist primarily of custom and foundry products and revenues from the license of patents. The chief operating decision maker evaluates segment performance based on revenue. Accordingly, all expenses are considered corporate level activities and are not allocated to segments. Therefore, it is not practical to show profit or loss by reportable segments. Also, the chief operating decision maker does not assign assets to these segments. Consequently, it is not relevant to show assets by reportable segments.

13. COMMITMENTS AND CONTINGENCIES

From time to time, claims have been filed by or have arisen against the Company in its normal course of business. Generally, litigation is subject to inherent uncertainties, and no assurance can be given that the Company will prevail in any particular lawsuit. Accordingly, litigation could result in substantial costs and diversion of resources and could have a material adverse effect on the Company’s financial condition, results of operations or cash flows.

As of June 30, 2013, the Company has not recorded any accrual for contingent liabilities associated with the legal proceedings described above based on the belief that liabilities, while possible, are not probable. Further, ranges of possible losses in these matters cannot be reasonably estimated at this time.

14. SHARE REPURCHASE PROGRAM

On July 26, 2012, the Company announced that its Board of Directors authorized the repurchase of $30.0 million of the Company’s common stock. As of June 30, 2013, the total remaining authorized amount available for repurchase was $14.5 million.

Shares of common stock purchased pursuant to the repurchase program are cancelled from outstanding shares upon repurchase. Share repurchases are recorded as a reduction to common stock to the extent available. Any amounts repurchased which are in excess of the existing total common stock balance are recorded as a reduction of retained earnings. Share repurchases are intended to reduce the number of outstanding shares of common stock to increase shareholder value and offset dilution from the Company’s stock incentive plans and ESPP. During the six months ended June 30, 2013, the Company repurchased 468,611 shares of its common stock for an aggregate price of $4.7 million.

15. INCOME TAXES

The income tax provision for the three and six months ended June 30, 2013, as a percentage of income before taxes was 19.1% and 12.2%, respectively. The income tax provision for the three months ended June 30, 2013 included income tax benefits totaling $424,000 pertaining to 2012 from the filing of 2012 foreign tax returns during the period. For the six months ended June 30, 2013, the income tax provision also included a $1.4 million benefit for 2012 research tax credits as a tax law was enacted on January 2, 2013 to retroactively reinstate the federal research and development tax credit to January 1, 2012.

The income tax provision for the three and six months ended June 30, 2012, as a percentage of income before taxes, was 33.4% and 33.5%, respectively. The tax provision for the three and six months ended June 30, 2012, included the recognition of $176,000 of previously unrecognized tax benefits due to settlements with the tax authorities. Additionally, the tax provision for the three and six months ended June 30, 2012 excluded any benefits from the federal research and development credit which expired on December 31, 2011 and had not been reinstated as of June 30, 2012.

As of June 30, 2013, the gross amount of unrecognized tax benefits for uncertain tax positions was $12.4 million (including interest and penalties) and the net amount, reduced for the federal effects of potential state tax exposures, was $9.0 million. Included in the $9.0 million is $5.3 million which has not yet reduced income tax payments, and therefore, has been netted against non-current deferred tax assets. The remaining $3.7 million liability consisted of $3.4 million included in long-term income taxes payable and $274,000 netted against short-term income taxes receivable. If these uncertain tax positions are sustained upon tax authority audit, or otherwise become certain, the $3.7 million would favorably affect the Company’s tax provision in such future periods. The Company does not anticipate a significant change to the amounts of unrecognized tax benefits presented as long-term liability or reduction to long-term deferred tax assets in the next 12 months.

The Company continues to recognize interest and penalties related to income tax matters as part of the income tax provision. As of June 30, 2013 and December 31, 2012, the Company had $435,000 and $354,000, respectively, accrued for interest and none accrued for penalties in both periods. These accruals are included as a component of long-term income taxes payable.

The Company is required to file U.S. federal income tax returns as well as income tax returns in various states and foreign jurisdictions. The Company may be subject to examination by the Internal Revenue Service (“IRS”) for calendar years 2009 and forward. Significant state tax jurisdictions include California, Massachusetts and Texas, and generally, the Company is subject to routine examination for years 2006 and forward in these jurisdictions. In addition, any research and development credit carryforwards that were generated in prior years and utilized in these years may also be subject to examination by respective state taxing authorities. Generally, the Company is subject to routine examination for years 2005 and forward in various immaterial foreign tax jurisdictions in which it operates.

MICREL, INCORPORATED

Deferred tax assets and liabilities result primarily from temporary differences between book and tax bases of assets and liabilities and state research and development credit carryforwards. The Company had net current deferred tax assets of $21.8 million and net long-term deferred tax liabilities of $133,000 as of June 30, 2013. The Company must regularly assess the likelihood that future taxable income levels will be sufficient to ultimately realize the tax benefits of these deferred tax assets. The Company currently believes that future taxable income levels will be sufficient to realize the tax benefits of these deferred tax assets and has not established a valuation allowance except for a valuation allowance of $8.2 million maintained against state deferred tax assets as of June 30, 2013. The recorded valuation allowance is primarily due to required income apportionment methods in California causing a shortfall of projected future taxable income to realize all available deferred tax assets in that jurisdiction. Should the Company determine that future realization of other recognized tax benefits is not more likely than not, additional valuation allowance would be established which would increase the Company's tax provision in the period of such determination.

16. DIVIDENDS

Cash dividends per common share for the year ended December 31, 2012 included an accelerated cash dividend of $0.0425 per share of common stock totaling $2.5 million paid on December 27, 2012 to shareholders of record as of December 18, 2012. The accelerated dividend was in lieu of the quarterly dividend that the Company would have otherwise announced in January 2013 with its quarterly financial results for the fourth quarter of 2012, and that would have been paid in February of 2013.

On April 25, 2013, the Company’s Board of Directors declared a cash dividend of $0.0425 per outstanding share of common stock. The aggregate payment of $2.5 million was made on May 22, 2013 to shareholders of record as of May 8, 2013.

On January 26, 2012, the Company's Board of Directors declared a cash dividend of $0.04 per outstanding share of common stock. The aggregate payment of $2.5 million was made on February 22, 2012 to shareholders of record as of February 8, 2012.

On April 26, 2012, the Company’s Board of Directors declared a cash dividend of $0.04 per outstanding share of common stock. The aggregate payment of $2.5 million was made on May 23, 2012 to shareholders of record as of May 9, 2012.

17. SUBSEQUENT EVENTS

On July 25, 2013, the Company’s Board of Directors declared a cash dividend of $0.05 per outstanding share of common stock payable on August 28, 2013 to shareholders of record at the close of business on August 14, 2013. This dividend will be recorded in the third quarter of 2013 and is expected to be approximately $2.9 million.

To enhance the readers’ understanding of the Company’s performance, the following is a chronological overview of the Company’s results for the quarterly periods from January 1, 2012 through March 31, 2013.

During the first quarter of 2012, revenues increased 4.0% to $61.2 million from $58.8 million in the fourth quarter of 2011. This increase in revenue from the fourth quarter of 2011 was principally driven by overall demand from customers in most geographies and end markets. As compared to the same period last year, first quarter 2012 revenues decreased by $6.3 million. First quarter 2012 book-to-bill ratio was one, and showed improvement compared to the fourth quarter of 2011. First quarter 2012 gross margin was 54.3%, as compared to 50.5% in the fourth quarter of 2011. With the higher revenues compared to the fourth quarter of 2011, first quarter 2012 gross margin increased from the previous quarter primarily due to a higher percentage of distribution sales which carry higher margins, an increase in factory utilization, and lower inventory reserve charges. Net income for the first quarter of 2012 was $5.9 million, or $0.10 per basic and diluted share, as compared to net income of $4.9 million, or $0.08 per basic and diluted share, for the fourth quarter of 2011, and net income of $9.1 million, or $0.15 per basic share and $0.14 per diluted share, for the first quarter of 2011. During the first quarter of 2012, cash flows from operations were $8.7 million. During the first quarter of 2012, cash and short-term investments decreased by $0.6 million to $137.3 million. In addition to maintaining its quarterly $0.04 per share cash dividend, during the first quarter of 2012 the Company repurchased $6.0 million of its common stock.

Revenues of $63.7 million in the second quarter of 2012 increased 4.2% from $61.2 million in the first quarter of 2012. The increase primarily resulted from stronger sales of the Company's timing and communications products, including contributions from the acquisition of PhaseLink. This growth was in part offset by weaker than expected demand from the Company's sell-through distributors primarily in Europe. The book-to-bill ratio in the second quarter of 2012 was above one. Second quarter 2012 gross margin increased to 55.2% as compared to 54.3% in the first quarter of 2012. The increase was principally due to a richer mix of higher-margin products and improved factory utilization. Net income attributable to Micrel, Incorporated shareholders for the second quarter of 2012 was $6.0 million, or $0.10 per basic and diluted share, as compared to net income of $5.9 million, or $0.10 per basic and diluted share, for the first quarter of 2012, and net income of $10.7 million, or $0.17 per basic and diluted share, for the second quarter of 2011. During the second quarter of 2012, cash flows from operations were $11.5 million. Cash and short term investments were $119.4 million at June 30, 2012 as compared to $137.3 million at March 31, 2012 which reflects a cash payment of $16.4 million (net of acquired cash) made on April 2, 2012 related to the PhaseLink acquisition. During the second quarter of 2012, the Company repurchased $8.7 million of its common stock. In addition, the Company maintained and paid its quarterly $0.04 per share cash dividend totaling approximately $2.5 million in the second quarter of 2012.

Third quarter 2012 revenues decreased 1.2% to $62.9 million from $63.7 million in the second quarter of 2012. The decrease was principally due to lower sales of the Company's timing and communications products partially offset by gathering momentum in LAN solutions product sales. The third quarter 2012 book-to-bill ratio was above one. Third quarter 2012 gross margin decreased to 52.9% as compared to 55.2 % in the second quarter of 2012 primarily due to a mix shift to lower margin consumer-related products and lower factory capacity utilization. The lower factory utilization was due to reducing production in an attempt to minimize building inventory. Net income attributable to the Company' shareholders for the third quarter of 2012 was $4.9 million, or $0.8 per basic and diluted share, as compared to net income of $6.0 million, or $0.10 per basic and diluted share, for the second quarter of 2012, and net income of $9.2 million, or $0.15 per basic and diluted share, for the third quarter of 2011. During the third quarter of 2012, cash flows from operations were $6.4 million. Cash and short term investments were $108.7 million at September 30, 2012 as compared to $119.4 million at June 30, 2012. During the third quarter of 2012, the Company spent $13.7 million repurchasing its common stock. Additionally, the Company maintained its quarterly $0.04 per share cash dividend for a total of approximately $2.2 million.

During the fourth quarter of 2012, revenues decreased slightly by 1.0 % to $62.3 million from $62.9 million in the third quarter of 2012. The decrease reflects lower sales in a difficult macroeconomic and industry environment. The fourth quarter 2012 book-to-bill ratio seasonally declined from the third quarter 2012 and was below one. Compared to the fourth quarter of 2011, revenues increased by $3.6 million, or 6.1%, primarily due to added revenues from the acquisition of PhaseLink. Fourth quarter 2012 gross margin declined sequentially to 50.3% from 52.9% in the third quarter of 2012 principally due to lower factory capacity utilization and increased inventory reserves. The lower factory utilization resulted from attempting to minimize building inventory. Net loss for the fourth quarter of 2012 was $4.5 million, or a loss of $0.08 per basic and diluted share, as compared to net income of $4.9 million, or $0.08 per basic and diluted share, for the third quarter of 2012, and net income of $4.9 million, or $0.08 per basic and diluted share, for the fourth quarter of 2011. Net loss for the fourth quarter of 2012 included a write-off of deferred tax assets totaling $7.6 million due to a change of California tax laws. During the fourth quarter of 2012, cash flows from operations were $6.0 million. Cash and short term investments were $103.6 million at December 31, 2012 as compared to $108.7 million at September 30, 2012. In the fourth quarter of 2012, the Company spent $6.1 million repurchasing its common stock and increased its quarterly cash dividend to $0.0425 per share for a total of approximately $2.5 million which was paid in November 2012. In addition, during December 2012, the Company declared an accelerated cash dividend of $0.0425 per share of common stock totaling $2.5 million paid on December 27, 2012 to shareholders of record as of December 18, 2012. The accelerated dividend was in lieu of the quarterly dividend that the Company would have otherwise announced with its quarterly financial results for the fourth quarter of 2012, and that would have been paid in the first quarter of 2013.

For the year ended December 31, 2012, revenues decreased 3.4% to $250.1 million from $259.0 million for the year ended December 31, 2011. The decrease was primarily due to the continued global downturn which impacted Europe to a greater degree resulting in less demand of the Company's products, partially offset by an increase of revenues from Asia due to added revenues from the acquisition of PhaseLink since the second quarter of 2012. The book-to-bill ratio was approximately one for the full year of 2012. Gross margin for 2012 decreased to 53.1% from 55.3% for 2011. The decrease was primarily due to lower factory utilization and increased inventory reserve charges. Operating margin for 2012 decreased to 11.1% from 18.1% for 2011 principally due to lower sales and increased spending in research and development. Net income was $12.3 million, or $0.20 per diluted share, compared with $33.9 million, or $0.54 per diluted share, in 2011. During 2012, cash, cash equivalents and short term investments decreased by $34.2 million from $137.9 million primarily due to repurchases of the Company's common stock totaling $34.6 million and $12.1 million paid in dividends to shareholders. Additionally, during 2012, the Company paid a total of $17.4 million net of cash acquired for the acquisition of PhaseLink.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

During the first quarter of 2013, revenues decreased 4.2% to $59.7 million from $62.3 million in the fourth quarter of 2012. With continued global macro-economic challenges, this decrease resulted primarily from lower demand in the computing and communications end markets, partially offset by an increase in revenues from the consumer end market. As compared to the same period last year, first quarter 2013 revenues decreased by $1.4 million, or 2.3%. First quarter 2013 book-to-bill ratio was 1:1 driven by strength in the industrial end market. First quarter 2013 gross margin was 52.0%, as compared to 50.3% in the fourth quarter of 2012. This increase in gross margin from the previous quarter was primarily due to a higher percentage of distribution sales which carry higher margins. Net income for the first quarter of 2013 was $5.2 million, or $0.09 per basic and diluted share, as compared to net loss of $4.5 million, or a loss of $0.08 per basic and diluted share, for the fourth quarter of 2012, and net income of $5.9 million, or $0.10 per basic and diluted share, for the first quarter of 2012. During the first quarter of 2013, cash flows from operations were $7.7 million. During the first quarter of 2013, cash and short-term investments increased by $8.1 million to $111.7 million. The increase was partly due to the cash dividend of $0.0425 per share of common stock totaling $2.5 million, which would have been paid in the first quarter of 2013, was accelerated and paid on December 27, 2012 to shareholders of record as of December 18, 2012. In addition, the Company did not repurchase any shares of its common stock.

Revenues for the second quarter of 2013 totaled $59.2 million, representing a decrease of $0.6 million, or 0.9%, from $59.7 million in the first quarter of 2013. The decrease was primarily due to lower sales to the Company's wireless handset end market which were down by 18.2%, partially offset by higher sales in the communications, computing, consumer and industrial end markets. As compared to the same quarter last year, second quarter of 2013 revenues decreased by $4.5 million, or 7.1%, principally resulting from lower demand from customers in the communications and wireless handset end markets. The book-to-bill ratio in the second quarter of 2013 was above one. The gross margin in the second quarter of 2013 was 52.5%, as compared to 52.0% in the first quarter of 2013. This increase was largely due to a product mix favoring a greater percentage of higher margin communications, computing and industrial products. The Company’s operating margin for the second quarter of 2013 increased to 10.4%, as compared to 9.1% in the first quarter of 2013. Net income for the second quarter of 2013 was $5.0 million, or $0.09 per basic and diluted share, as compared to net income of $5.2 million, or $0.09 per basic and diluted share, for the first quarter of 2013, and net income of $6.0 million, or $0.10 per basic and diluted share, for the second quarter of 2012. During the second quarter of 2013, cash flows from operations were $2.0 million. Cash and short term investments were $104.9 million at June 30, 2013 as compared to $111.7 million at March 31, 2013. During the second quarter of 2013, the Company repurchased $4.7 million of its common stock and maintained its quarterly $0.0425 per share dividend totaling $2.5 million.

The Company derives a substantial portion of its net revenues from standard products. For the three and six months ended June 30, 2013 and 2012, the Company’s standard products sales accounted for 97% and 96%, respectively, of the Company’s net revenues. The Company believes that a substantial portion of its net revenues in the future will depend upon standard products sales, although such sales as a proportion of net revenues may vary as the Company adjusts product output levels to correspond with varying economic conditions and demand levels in the markets which it serves. The standard products business is characterized by short-term orders and shipment schedules, and customer orders typically can be canceled or rescheduled without significant penalty to the customer. Since most standard products backlog is cancelable without significant penalty, the Company typically plans its production and inventory levels based on forecasts of customer demand, which are highly unpredictable and can fluctuate substantially. In addition, the Company is limited in its ability to reduce costs quickly in response to any revenue shortfalls.

The Company may experience significant fluctuations in its results of operations. Factors that affect the Company’s results of operations include the volume and timing of orders received, changes in the mix of products sold, levels of inventory and resales by distributors, the utilization level of manufacturing capacity, competitive pricing pressures and the successful development and customer acceptance of new products. These and other factors are described in further detail later in this discussion and in Part II Item 1A of this Quarterly Report on Form 10-Q titled “Risk Factors.” As a result of the foregoing or other factors, there can be no assurance that the Company will not experience material fluctuations in future operating results on a quarterly or annual basis, which could materially and adversely affect the Company’s business, financial condition, results of operations and cash flows.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Critical Accounting Policies and Estimates

The financial statements included in this Quarterly Report on Form 10-Q and discussed within this Management’s Discussion and Analysis of Financial Condition and Results of Operations have been prepared in accordance with accounting principles generally accepted in the United States of America. Preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments. Management bases its estimates and judgments on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The Company considers certain accounting policies related to revenue recognition and receivables, inventory valuation, share-based compensation, and income taxes to be critical to the fair presentation of its financial statements. For a detailed discussion of the Company’s significant accounting policies, see Note 1 to Condensed Consolidated Financial Statements in this report and Note 1 of Notes to Consolidated Financial Statements in Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Revenue Recognition and Receivables. The Company generates revenue by selling products to original equipment manufacturer ("OEM") customers, sell-through distributors and sell-in distributors. Sell-in distributors may buy and stock the Company’s products for resale or may act as the Company’s sales representative in arranging for direct sales from the Company to an OEM customer. The Company’s policy is to recognize revenue from sales to customers when the rights and risks of ownership have passed to the customer, when persuasive evidence of an arrangement exists, the product has been delivered, the price is fixed or determinable and collection of the resulting receivable is reasonably assured.

The Company allows certain sell-through distributors located in North America and Europe, and in certain countries in Asia, to have price protection and pricing adjustments subsequent to the initial product shipment. As these price concessions have historically been significant, and price concessions are difficult to reliably estimate, the Company defers recognition of revenue and related cost of sales (in the balance sheet line item "deferred income on shipments to distributors") derived from sales to these sell-through distributors until they have resold the Company’s products to their customers. Although revenue and related cost of sales are not recognized, the Company records an accounts receivable and relieves inventory at the time of initial product shipment. As standard terms are FOB shipping point, payment terms are enforced from shipment date and legal title and risk of inventory loss passes to the sell-through distributor upon shipment.

In addition, where revenue is deferred upon shipment and recognized on a sell-through basis, the Company may offer price adjustments to its sell-through distributors to allow the distributor to price the Company’s products competitively for specific resale opportunities. The Company estimates and records an allowance for distributor price adjustments for which the specific resale transaction has been completed, but the price adjustment claim has not yet been received by the Company.

Sales to OEM customers and sell-in distributors are recognized based upon the shipment terms of the sale transaction when all other revenue recognition criteria have been met. The Company does not grant return rights, price protection or pricing adjustments to OEM customers. The Company offers limited contractual stock rotation rights to sell-in distributors. In addition, the Company is not contractually obligated to offer, but may infrequently grant, price adjustments or price protection to certain sell-in distributors on an exception basis. At the time of shipment to OEMs and sell-in distributors, an allowance for returns is established based upon historical return rates, and an allowance for price adjustments is established based on an estimate of price adjustments to be granted. Actual future returns and price adjustments could be different than the allowance established.

The Company also maintains an allowance for doubtful accounts for estimated uncollectible accounts receivable. This estimate is based on an analysis of specific customer creditworthiness and historical bad debts experience. Actual future uncollectible amounts could exceed the doubtful accounts allowance established.

Inventory Valuation. Inventories are stated at the lower of cost (first-in, first-out method) or market. The Company records adjustments to write down the cost of obsolete and excess inventory to the estimated market value based on historical and forecasted demand for its products. If actual future demand for the Company’s products is less than currently forecasted, additional inventory adjustments may be required. Once an inventory write-down provision is established, it is maintained until the product to which it relates is sold or otherwise disposed of.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Share-Based Compensation. Share-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense in the statement of operations. To determine fair value, the Company uses the Black-Scholes valuation model which requires input factors such as expected term, stock price volatility, dividend yield and a risk free interest rate. In addition, the Company estimates expected forfeiture rates of stock grants and share-based compensation expense is only recognized for those shares expected to vest. Determining the input factors, such as expected term, expected volatility and estimated forfeiture rates, requires significant judgment based on subjective future expectations.

Income Taxes. Deferred tax assets and liabilities result primarily from temporary timing differences between book and tax valuation of assets and liabilities, and state research and development credit carryforwards. The Company must regularly assess the likelihood that future taxable income levels will be sufficient to ultimately realize the tax benefits of these deferred tax assets. As of June 30, 2013, the Company believes that future taxable income levels will be sufficient to realize the tax benefits of these deferred tax assets and has not established a valuation allowance except for a valuation allowance that was established against deferred assets due to California tax law changes in 2012 which require a mandatory single sales factor apportionment in California for most multi-state taxpayers for tax years beginning on or after January 1, 2013. Should the Company determine that future realization of other recognized deferred tax assets is not more likely than not, additional valuation allowance would be established, which would increase the Company’s tax provision in the period of such determination.

The Company uses a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Net Revenues. For the three months ended June 30, 2013, net revenues decreased 7% to $59.2 million from $63.7 million for the same period in the prior year. The decease primarily resulted from reduced demand of the Company's products serving the communications and wireless handset end markets. For the six months ended June 30, 2013, net revenues decreased 5% to $118.9 million from $124.9 million for the same period in the prior year. The decrease was principally due to lower demand from the wireless handset, communications and computing end markets, partially offset by revenues from the acquisition of PhaseLink and higher demand from the industrial end market. The decreases in revenues for the three and six months ended June 30, 2013 reflect lower revenues from both the Company's standard and other products as compared to the same periods in the prior years.

As noted in Part II, Item 1A “Risk Factors,” customers in the semiconductor supply chain have worked to minimize the amount of inventory of semiconductors they hold. As a consequence, customers are generally providing less order backlog to the Company and other semiconductor suppliers, and relying on short lead times to buffer their build schedules. Shorter lead times reduce visibility into end demand and increase the reliance on turns fill orders. The reluctance of customers to provide order backlog together with short lead times and the uncertain growth rate of the world economy, make it difficult to precisely predict future levels of sales and profitability.

International sales represented 71% and 70% of net revenues for the three and six months ended June 30, 2013, respectively, as compared to 71% and 72% of net revenues for the three and six months ended June 30, 2012, respectively. Sales to customers in Asia represented 59% and 57% of net revenues for both the three and six months ended June 30, 2013, respectively, as compared to 59% of net revenues for both the three and six months ended June 30, 2012. The trend for the Company’s customers to move their electronics manufacturing to Asian countries has resulted in increased pricing pressure for the Company and other semiconductor manufacturers as Asia-based manufacturers are typically highly cost sensitive. This can make it more difficult for U.S.-based companies to differentiate themselves in any meaningful manner other than by lowering prices. The increased concentration of electronics procurement and manufacturing in the Asia Pacific region has led, and may continue to lead, to continued price pressure for the Company’s products in the future.

Gross Profit. Gross profit is affected by a variety of factors including the volume of product sales, product mix, manufacturing capacity utilization, product yields and average selling prices. The Company’s gross margin decreased to 52.5% for the three months ended June 30, 2013 from 55.2% for the comparable period in 2012. For the six months ended June 30, 2013, the Company’s gross margin decreased to 52.3% from 54.7% for the comparable period in 2012. These decreases were primarily due to lower factory capacity utilization and higher inventory reserves, partially offset by a better product mix as compared to the same periods in 2012.

Research and Development Expenses.Research and development expenses as a percentage of net revenues represented 22.8% for the three months ended June 30, 2013 as compared to 21.9% for the three months ended June 30, 2012. On a dollar basis, research and development expenses decreased $419,000, or 3.0%, to $13.5 million for the three months ended June 30, 2013 from $13.9 million for the comparable period in 2012. This decrease was primarily due to reduced spending on test boards and mask sets, decreased outside consulting services and lower share-based compensation expense, partially offset by increased prototype fabrication costs.

For the six months ended June 30, 2013 and 2012, research and development expenses as a percentage of net revenues represented 22.9% and 21.8%, respectively. On a dollar basis, research and development expenses increased $28,000 to $27.3 million for the six months ended June 30, 2013 from $27.2 million for the comparable period in 2012. The increase was primarily due to headcount expenses from the acquisition of PhaseLink and increased prototype fabrication costs, mostly offset by lower outside consulting services and share-based compensation expense. The Company believes that the development and introduction of new products is critical to its future success and expects to continue its investment in research and development activities in the future.

Selling, General and Administrative Expenses. As a percentage of net revenues, selling, general and administrative expenses represented 19.3% for the three months ended June 30, 2013 and 19.1% for the three months ended June 30, 2012. On a dollar basis, selling, general and administrative expenses decreased $746,000, or 6.1%, to $11.4 million for the three months ended June 30, 2013 from $12.2 million for the comparable period in 2012. This decrease was primarily due to spending reductions on product and corporate marketing activities, personnel and commissions, partially offset by increased incentive bonus expense.

24

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

For the six months ended June 30, 2013 and 2012, selling, general and administrative expenses as a percentage of net revenues represented 19.6% and 18.7%, respectively. On a dollar basis, selling, general and administrative expenses decreased $45,000 to $23.3 million for the six months ended June 30, 2013 from $23.3 million for the comparable period in 2012. The decrease was primarily due to lower spending on product and corporate marketing activities, commissions and travel, mostly offset by increased corporate bonus expense, headcount expenses from the acquisition of PhaseLink as well as related amortization expenses of acquired intangible assets.

Share-Based Compensation. The Company’s results of operations for the three month periods ended June 30, 2013 and 2012 included $1.7 million and $1.9 million, respectively, of non-cash expense related to the fair value of share-based compensation awards. For the six month periods ended June 30, 2013 and 2012, the Company’s results of operations included $3.3 million and $3.7 million, respectively, of share-based compensation awards. Share-based compensation expense is included in the statement of operations in cost of revenues, research and development expenses and selling, general and administrative expenses (see Note 3 of Notes to Condensed Consolidated Financial Statements).

Other Income (Expense). Other income, net reflects interest income from investments in short-term and long-term investment securities and money market funds and other non-operating income or expense related primarily to foreign currency gain or loss, offset by interest expense incurred.

Provision for Income Taxes.The income tax provision for the three and six months ended June 30, 2013, as a percentage of income before taxes, was 19.1% and 12.2%, respectively. The income tax provision for the three and six months ended June 30, 2012, as a percentage of income before taxes, was 33.4% and 33.5%, respectively. The income tax provision for the three months ended June 30, 2013 included income tax benefits totaling $424,000 pertaining to 2012 from the filing of 2012 foreign tax returns during the period. For the six months ended June 30, 2013, the income tax provision also included a $1.4 million benefit for 2012 research tax credits as a tax law was enacted on January 2, 2013 to retroactively reinstate the federal research and development tax credit to January 1, 2012. The tax provision for the three and six months ended June 30, 2012, included the recognition of $176,000 of previously unrecognized tax benefits due to settlements with the tax authorities. Additionally, the tax provision for the three and six months ended June 30, 2012 excluded any benefits from the federal research and development credit which expired on December 31, 2011 and had not been reinstated as of June 30, 2012. The income tax provision for these interim periods differs from taxes computed at the federal statutory rate primarily due to the tax effects of share-based compensation, state income taxes, federal and state research and development credits and federal qualified production activity deductions.

Liquidity and Capital Resources

Since inception, the Company’s principal sources of funding have been its cash from operations, bank borrowings and sales of common stock. Principal sources of liquidity at June 30, 2013 consisted of cash, cash equivalents and short-term investments of $104.9 million and a $5.0 million revolving line of credit from a commercial bank.

The Company generated $9.8 million in cash from operating activities during the six months ended June 30, 2013. Significant cash flows included cash provided by net income of $10.3 million plus additions for non-cash activities of $6.7 million (consisting primarily of $6.6 million in depreciation and amortization, $3.1 million in share-based compensation expense and related tax effects, partially offset by a $3.0 million increase in deferred income taxes) combined with a $6.2 million increase in deferred income on shipments to distributors, a $1.7 million decrease in income taxes receivable and a $1.0 million increase in other current liabilities which were offset in part by a $7.9 million increase in accounts receivable and a $7.5 million decrease in accounts payable.

The Company generated $20.2 million in cash from operating activities during the six months ended June 30, 2012. Significant cash flows included cash provided by net income of $11.9 million plus additions for non-cash activities of $8.0 million (consisting primarily of $6.1 million in depreciation and amortization and $3.7 million in share-based compensation expense and related tax effects, partially offset by a $2.2 million increase in deferred income taxes) combined with a $6.9 million decrease in income taxes receivable which was offset in part by a $4.6 million increase in accounts receivable, a $1.1 million decrease in accounts payable and a $0.9 million decrease in other current liabilities.

The Company provided $8.0 million of cash from investing activities during the six months ended June 30, 2013, primarily comprised of $47.5 million in proceeds from the sales and maturities of investments, which was partially offset by $35.8 million in purchases of investments and $3.9 million of purchases of property, plant and equipment.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The Company used $26.3 million of cash in investing activities during the six months ended June 30, 2012, comprised of $30.6 million in purchases of investments, $16.4 million in the acquisition of PhaseLink and $4.1 million in purchases of property, plant and equipment, which were partially offset by $24.8 million in proceeds from the sales and maturities of investments.

The Company used $5.0 million of cash in financing activities during the six months ended June 30, 2013 primarily for the repurchases of $4.7 million of the Company's common stock and $2.5 million for the payment of cash dividends, which were partially offset by $2.4 million in proceeds from employee stock transactions.

The Company used $18.5 million of cash in financing activities during the six months ended June 30, 2012 primarily for the repurchases of $14.7 million of its common stock and $4.9 million for the payment of cash dividends, which were partially offset by $1.5 million in proceeds from employee stock transactions.

The Company currently intends to spend approximately $4.0 million to $8.0 million to purchase capital equipment and make facility improvements during the next twelve months primarily for manufacturing equipment and additional research and development related software and equipment.

On July 25, 2013, the Company’s Board of Directors declared a cash dividend of $0.05 per outstanding share of common stock payable on August 28, 2013 to shareholders of record at the close of business on August 14, 2013. This dividend will be recorded in the third quarter of 2013 and is expected to be approximately $2.9 million.

Under the Company’s stock repurchase program, as of June 30, 2013, the Company was authorized to repurchase an additional $14.5 million of its common stock.

The Company believes that its cash from operations, existing cash balances, short-term investments and its credit facility will be sufficient to meet its cash requirements for at least the next twelve months. In the longer term, the Company believes future cash requirements will continue to be met by its cash from operations, credit arrangements and future debt or equity financings as required.

Recently Issued Accounting Standards

Please refer to Note 2 of Notes to Condensed Consolidated Financial Statements for a discussion of the expected impact of recently issued accounting standards.

Contractual Obligations and Commitments

As of June 30, 2013 the Company had the following contractual obligations and commitments (in thousands):

	Payments Due By Period
	Total		Less than 1 Year		1-3 Years			4-5 Years		After 5 Years
Operating leases	$	2,158	$	1,008	$	975	175	$	175	$	—
Open purchase orders	19,966		19,966		—			—		—
Total	$	22,124	$	20,974	$	975		$	175	$	—

Open purchase orders are defined as agreements to purchase goods or services that are enforceable and legally binding and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable pricing provisions; and the approximate timing of the transactions.

Borrowing agreements consisted of an unsecured credit facility with Bank of the West. The credit facility includes a $5.0 million line of credit available for general working capital needs, a $5.0 million letter of credit sub-facility and a $2.0 million foreign exchange sub-facility. The Company's borrowing arrangements include a provision for the issuance of commercial or standby letters of credit by the bank on behalf of the Company. As of June 30, 2013, there was $325,000 in letters of credit outstanding. The letters of credit are issued to guarantee payments for the Company's workers compensation program. As of June 30, 2013, the Company had no borrowings under the line of credit.

26

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

As of June 30, 2013, the Company had $9.0 million of net unrecognized tax benefits. Included in the $9.0 million is $5.3 million which has not yet reduced income tax payments, and therefore, has been presented as a reduction to non-current deferred tax assets. The remaining $3.7 million presented as a liability consisted of $3.4 million included in long-term income taxes payable and $274,000 reduction in short-term income taxes receivable. The Company does not anticipate a significant change to the amount of long-term unrecognized tax benefits related to certain income tax positions within the next 12 months.

Off-Balance Sheet Arrangements

As of June 30, 2013, the Company had no off-balance sheet arrangements and has not entered into any transactions involving unconsolidated, limited purpose entities or commodity contracts.

27

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company usually invests cash in investments with short maturities or with frequent interest reset terms. Accordingly, interest income fluctuates with short-term market conditions. As of June 30, 2013, the Company's investment portfolio consisted primarily of corporate debt securities, commercial paper and liquid municipal debt securities with maturities ranging from less than one month to less than two years and were classified as available-for-sale securities. With the exception of the auction rate notes (discussed below), these investments were relatively liquid. Due to the relatively short, weighted-average maturity of the Company's investment portfolio and the current low interest rate environment, the Company's exposure to interest rate risk is minimal.

At June 30, 2013, the Company held $4.7 million in principal of senior auction rate notes secured by student loans with a fair value of $4.2 million. Auctions for these auction rate notes have failed as of June 30, 2013. The funds associated with failed auctions will not be accessible until a successful auction occurs, a buyer is found outside of the auction process, the issuers redeem the securities or the underlying securities have matured. As a result, the Company may have limited or no ability to liquidate its investment and fully recover the carrying value of its investment in the near term. As of June 30, 2013, the Company has recorded a $315,000 net of tax ($484,000 pre-tax) temporary impairment of these securities to other comprehensive income, a component of shareholders’ equity. If it is determined that the fair value of these securities is other than temporarily impaired, the Company would record a loss, which could be material, in its statement of operations in the period such other than temporary decline in fair value is determined. The Company currently has the ability and intent to hold these investments until a recovery of the auction process occurs or the issuers redeem the securities, or until maturity if neither of those occurs.

The company had no fixed-rate long-term debt subject to interest rate risk and no interest rate swap or foreign currency hedging contracts. At June 30, 2013, the Company had no derivative instrument contracts outstanding.

ITEM 4. CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Under the supervision and with the participation of the Company’s management, including its principal executive officer and principal financial officer, the Company conducted an evaluation of the effectiveness of its disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation, the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2013.

There has been no change in the Company’s internal control over financial reporting during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Our management, including our principal executive officer and principal financial officer, believes that our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level. However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The information included in Note 13 of Notes to Condensed Consolidated Financial Statements under the caption "Commitments and Contingencies" in Item 1 of Part I is incorporated herein by reference.

ITEM 1A. RISK FACTORS

Set forth below and elsewhere in this report and in other documents we file with the SEC are descriptions of the risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this report. The description below includes any material changes to and supersedes the description of the risk factors affecting our business previously discussed in "Part I, Item 1A Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

Factors That May Affect Operating Results

If the Company’s operating results are below the expectations of public market analysts or investors, then the market price of its common stock could decline. Many factors that can affect the Company’s quarterly and annual results are difficult to control or predict. Some of the factors which can affect a multinational semiconductor business such as the Company are described below.

Geopolitical and Macroeconomic Risks That May Affect Multinational Enterprises

Weak global economic conditions could have a material adverse effect on the Company’s business, results of operations, and financial condition. While the global economy has partially recovered from the economic downturn that began in 2007, continued weakness in the macroeconomic climate has constrained demand for the Company’s semiconductors and there is no guarantee that these conditions will improve in a timely manner or at all or that these conditions will not further decline again in the future. The semiconductor industry has traditionally been highly cyclical and has often experienced significant downturns in connection with, or in anticipation of, declines in general economic conditions. The Company cannot accurately predict the timing, severity or duration of such downturns. A global recession may result in a decrease in orders for the Company’s products, which may materially adversely affect the Company’s revenues, results of operations and financial condition. In addition to reduction in sales, the Company’s profitability may decrease during economic downturns because the Company may not be able to reduce costs at the same rate as its sales decline.

Demand for semiconductor components is increasingly dependent upon the rate of growth of the global economy. Many factors could adversely affect regional or global economic growth. Some of the factors that could slow global economic growth include: volatility in global credit markets, price inflation or deflation for goods, services or materials, a slowdown in the rate of growth of regional economies such as Europe, China or the United States, a significant act of terrorism that disrupts global trade or consumer confidence, and geopolitical tensions including war and civil unrest. Reduced levels of economic activity, or disruptions of international transportation, could adversely affect sales on either a global basis or in specific geographic regions.

Market conditions may lead the Company to initiate cost reduction plans, which may negatively affect near term operating results. Weaker customer demand, competitive pricing pressures, continued excess capacity, weak economic conditions or other factors, may cause the Company to initiate actions to reduce the Company’s cost structure to improve the Company’s future operating results. The cost reduction actions may require incremental costs to implement, which could negatively affect the Company’s operating results in periods when the incremental costs or liabilities are incurred.

Disruption in financial markets may adversely affect the Company’s business in a number of ways. The unprecedented contraction and extreme disruption of the credit and financial markets in the United States, Europe and Asia that began in 2007 led to, among other things, extreme volatility in security prices, severely diminished liquidity and credit availability, rating downgrades of certain investments and declining valuation of others. A similar tightening of credit in financial markets in the future may limit the ability of the Company’s customers and suppliers to obtain financing for capital purchases and operations. This could result in a decrease in or cancellation of orders for the Company’s products or reduced ability to finance operations to supply products to the Company. The Company cannot predict the likely duration and severity of disruptions in financial markets and adverse economic conditions in the United States and other countries. Further, fluctuations in worldwide economic conditions make it extremely difficult for the Company to forecast future sales levels based on historical information and trends. Visibility into customer demand is limited due to short order lead times. Portions of the Company’s expenses are fixed and other expenses are tied to expected levels of sales activities. To the extent the Company does not achieve its anticipated levels of sales, its gross profit and net income could be adversely affected.

29

The Company has generated a substantial portion of its net revenues from export sales. The Company believes that a substantial portion of its future net revenues will continue to depend on export sales to customers in international markets, including Asia. International markets are subject to a variety of risks, including changes in policy by the U.S. or foreign governments, acts of terrorism, natural disasters, foreign government instability, social conditions such as civil unrest, economic conditions including high levels of inflation or deflation, fluctuation in the value of foreign currencies and currency exchange rates and trade restrictions or prohibitions. Changes in exchange rates that strengthen the U.S. dollar could increase the price of the Company’s products in the local currencies of the foreign markets it serves. This would result in making the Company’s products relatively more expensive than its competitors’ products that are denominated in local currencies, leading to a reduction in sales or profitability in those foreign markets. The Company has not taken any protective measures against exchange rate fluctuations, such as purchasing hedging instruments. In addition, the Company sells to domestic customers that do business worldwide and cannot predict how the businesses of these customers may be affected by economic or political conditions elsewhere in the world. Such factors could adversely affect the Company’s future revenues, financial condition, results of operations or cash flows.

Semiconductor Industry Specific Risks

The volatility of customer demand in the semiconductor industry limits a company’s ability to predict future levels of sales and profitability. Semiconductor suppliers can rapidly increase production output in response to slight increases in demand, leading to a sudden oversupply situation and a subsequent reduction in order rates and revenues as customers adjust their inventories to account for shorter lead times. A rapid and sudden decline in customer demand for products can result in excess quantities of certain products relative to demand. Should this occur, the Company’s operating results may be adversely affected as a result of charges to reduce the carrying value of the Company’s inventory to the estimated demand level or market price. The Company’s quarterly revenues are highly dependent upon turns fill orders (orders booked and shipped in the same quarter). The short-term and volatile nature of customer demand makes it extremely difficult to accurately predict near term revenues and profits.

The semiconductor industry is highly competitive and subject to rapid technological change, price-erosion and increased international competition. Significant competitive factors include product features; performance and price; timing of product introductions; emergence of new computer and communications standards; and quality and customer support. If the Company is unable to compete favorably in these areas, revenues and profits could be negatively affected.

The short lead-time environment in the semiconductor industry has allowed many end consumers to rely on semiconductor suppliers, sell-in distributors and sell-through distributors to carry inventory to meet short-term requirements and minimize their investment in on-hand inventory. Customers have worked to minimize the amount of inventory of semiconductors they hold. As a consequence, customers are generally providing less order backlog to the Company and other semiconductor suppliers, resulting in short order lead times and reduced visibility into customer demand. As a consequence of the short lead-time environment and corresponding unpredictability of customer demand, the Company has increased its inventories over the past several years to maintain reliable service levels. If actual customer demand for the Company’s products is different from the Company’s estimated demand, delivery schedules may be impacted, product inventory may have to be scrapped, or the carrying value reduced, which could adversely affect the Company’s business, financial condition, results of operations, or cash flows.

In addition, the Company uses sell-in distributors and sell-through distributors that carry inventory to service the volatile short-term demands of end customers. However, like many of its competitors, the Company generally recognizes revenue on sales of product to sell-in distributors upon shipment, so fluctuations in inventory accumulation by sell-in distributors can exacerbate fluctuations in revenue from sales to such sell-in distributors. Also, should the relationship with a sell-through distributor or sell-in distributor be terminated, the level of product returns could be higher than the returns allowance established, which could negatively affect the Company’s revenues and results of operations.

Uncertain economic growth and customer demand in the semiconductor industry and increased concentration of electronics procurement and manufacturing may lead to further price erosion and increased advertising costs. If price erosion continues to occur, it will have the effect of reducing revenue levels and gross margins in future periods. Furthermore, the trend for the Company’s customers to move their electronics manufacturing to Asian countries has brought increased pricing pressure for Micrel and the semiconductor industry as a whole. Asian-based manufacturers are typically highly cost sensitive. The increased concentration of electronics procurement and manufacturing in the Asia Pacific region may lead to continued price pressure and additional product advertising costs for the Company’s products in the future.

30

Many semiconductor companies, including the Company, face risks associated with a dependence upon third parties that manufacture, assemble, package or supply raw materials for certain of its products. These risks include reduced control over delivery schedules and quality; inadequate manufacturing yields and excessive costs; the potential lack of adequate capacity during periods of excess demand; difficulties selecting and integrating new subcontractors; potential increases in prices; disruption in supply due to civil unrest, terrorism, natural disasters or other events which may occur in the countries in which the subcontractors or suppliers operate; and potential misappropriation of the Company’s intellectual property. The occurrence of any of these events may lead to increased costs or delay delivery of the Company’s products, which would harm its profitability and customer relationships. Furthermore, a major disruption to any part of the Company’s customers’ supply chains could decrease their output and subsequently result in lower demand for the Company’s products.

The Company generally does not have long-term supply contracts with its third-party vendors. Therefore, most of its vendors are not obligated to perform services or supply products to the Company for any specific period, in any specific quantities, or at any specific price, except as may be provided in a particular accepted purchase order or guarantee. Additionally, the Company’s wafer and product requirements typically represent a relatively small portion of the total production of the suppliers, third-party foundries and outside assembly, testing and packaging contractors. As a result, the Company is subject to the risk that a third-party supplier will provide delivery or capacity priority to other larger customers to the Company’s detriment, resulting in an inadequate supply to meet customer demand or higher costs to obtain the necessary product supply. Furthermore, the Company's third-party vendors may be unwilling to supply certain products and processes or may be unable to do so due to business failure or bankruptcy. If replacement suppliers or manufacturing processes are not available, we may experience delays in shipment or lost revenue which could, in turn, result in temporary or permanent loss of customers.

The Company outsources some of its wafer fabrication, most of its test and all of its assembly requirements to third-party vendors. When demand for semiconductors improves, availability of these outsourced services typically becomes tight, resulting in longer than normal lead times and delinquent shipments to customers. The degree to which Micrel may have difficulty obtaining these services could have a negative impact on the Company’s revenues, bookings and backlog. If these lead times are extended, the resulting loss of near-term visibility for our customers could result in their placing higher order levels than their actual requirements which may result in higher levels of order cancellations in the future. There can be no assurance that the Company will be able to accurately forecast demand and moderate its build schedules to accommodate the possibility of an increase in order cancellations.

The markets that the Company serves frequently undergo transitions in which products rapidly incorporate new features and performance standards on an industry-wide basis. If the Company’s products are unable to support the new features or performance levels required by OEMs in these markets, the Company would likely lose business from existing or potential customers and would not have the opportunity to compete for new design wins until the next product transition. If the Company fails to develop products with required features or performance standards or experiences even a short delay in bringing a new product to market, or if its customers fail to achieve market acceptance of their products, its revenues could be significantly reduced for a substantial period of time.

Because the standard products market for ICs is diverse and highly fragmented, the Company encounters different competitors in various market areas. Many of these competitors have substantially greater technical, financial and marketing resources and greater name recognition than the Company. The Company may not be able to compete successfully in either the standard products or custom and foundry products businesses in the future and competitive pressures may adversely affect the Company’s financial condition, results of operations or cash flows.

The success of companies in the semiconductor industry depends in part upon intellectual property, including patents, trade secrets, know-how and continuing technology innovation. The success of companies like Micrel may depend on their ability to obtain necessary intellectual property rights and protect such rights. There can be no assurance that the steps taken by the Company to protect its intellectual property will be adequate to prevent misappropriation or that others will not develop competitive technologies or products. There can be no assurance that any patent owned by the Company will not be invalidated, circumvented or challenged, that the rights granted thereunder will provide competitive advantages or that any of its pending or future patent applications will be issued with the scope of the claims sought, if at all. Furthermore, others may develop technologies that are similar or superior to the Company’s technology, duplicate technology or design around the patents owned by the Company.

31

Additionally, the semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights. Claims alleging infringement of intellectual property rights have been asserted against the Company in the past and could be asserted against the Company in the future. These claims could result in the Company having to discontinue the use of certain processes or designs; cease the manufacturing, use and sale of infringing products; incur significant litigation costs and damages; attempt to obtain a license to the relevant intellectual property and develop non-infringing technology. The Company may not be able to obtain or renew such licenses on acceptable terms or to develop non-infringing technology. Existing claims or other assertions or claims for indemnity resulting from infringement claims could adversely affect the Company’s business, financial condition, results of operations or cash flows. In addition, the Company relies on third parties for certain technology that is integrated into some of its products. If the Company is unable to continue to use or license third-party technologies in its products on acceptable terms, or the technology fails to operate, the Company may not be able to secure alternative technologies in a timely manner and its business would be harmed.

The significant investment in semiconductor manufacturing capacity and the rapid growth of circuit design centers in China may present a competitive threat to established semiconductor companies due to the current low cost of labor and capital in China. The emergence of low cost competitors in China could reduce the revenues and profitability of established semiconductor manufacturers, such as Micrel.

There is intense competition for qualified personnel in the semiconductor industry. The loss of any key employees or the inability to attract or retain qualified personnel, including management, engineers and sales and marketing personnel, could delay the development and introduction of the Company’s products and harm its ability to sell its products. The Company believes that its future success is dependent on the contributions of its senior management, including its President and Chief Executive Officer, certain other executive officers and senior engineering personnel. The Company does not have long-term employment contracts with these or any other key personnel, and their knowledge of the Company’s business and industry would be difficult to replace.

Companies in the semiconductor industry are subject to a variety of federal, state and local governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in its manufacturing process. Any failure to comply with present or future regulations could result in the imposition of fines, the suspension of production, alteration of manufacturing processes or a cessation of operations. In addition, these regulations could restrict the Company’s ability to expand its facilities at their present locations or construct or operate a new wafer fabrication facility or could require the Company to acquire costly equipment or incur other significant expenses to comply with environmental regulations or clean up prior discharges. The Company’s failure to appropriately control the use of, disposal or storage of, or adequately restrict the discharge of, hazardous substances could subject it to future liabilities and could have a material adverse effect on its business.

New rules that impose diligence and disclosure requirements relating to “conflict minerals” may force the Company to incur significant expenses, may result in damage to its business reputation and may adversely impact its business, financial condition or operating results. In August 2012, under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the Securities and Exchange Commission (“SEC”) adopted rules imposing diligence and disclosure requirements on companies that use certain minerals referred to as "conflict minerals" regardless of their actual country of origin, in their products. Some of these metals are commonly used in electronic components and devices, including the Company's products. These new requirements require companies to investigate, disclose and report whether or not such metals originated from the Democratic Republic of Congo or adjoining countries. The Company's supply chain is very complex, with many suppliers that may not be obligated to investigate their own supply chains for the components and parts used in the Company's products. As a result, the Company may incur significant expenses to comply with the diligence and disclosure requirements, including costs related to determining the source of any of the relevant metals used in its products. In addition, because the Company's supply chain is so complex, the Company may not be able to sufficiently verify the origin of all the relevant metals used in its products through the due diligence procedures that the Company will implement, which may harm its business reputation. The Company may also face difficulties in satisfying its customers if they require the Company to prove or certify that its products are "conflict free" in the event that the customers need to know whether the Company's conflict mineral status satisfies their SEC reporting obligations. If the Company is not able to meet the requirements, customers may choose to disqualify the Company as a supplier. These rules may also affect the sourcing and availability of minerals used in the manufacturing of the Company's semiconductor devices as there may be only a limited number of suppliers offering conflict free components that can be used in the Company's products. There can be no assurance that the Company will be able to obtain such components in sufficient quantities or at competitive prices. The cost of compliance to the Company's service providers, foundries, subcontractors and suppliers could also be passed along to the Company, resulting in higher prices for the materials or components that the Company uses in its products. Any of these outcomes could adversely impact the Company's business, financial condition or operating results.

32

Company-Specific Risks

In addition to the risks that affect multinational semiconductor companies listed above, there are additional risks which are more specific to the Company such as:

An important part of the Company’s strategy is to continue to focus on the market for high-speed communications ICs. Should demand from the Company’s customers in this end market decrease, or if lower customer demand for the Company’s timing and communications products materializes, the Company’s future revenue growth and profitability could be adversely affected.

The wireless handset (cellular telephone) market comprises a significant portion of the Company’s net revenues. The Company derives a significant portion of its net revenues from a few customers serving the wireless handset market. Due to the highly competitive and fast changing environment in which the Company’s wireless handset customers operate, demand for the product the Company sells into this end market can change rapidly and unexpectedly. If the Company’s wireless handset customers’ acceptance of Micrel’s products decreases, or if these customers lose market share or accumulate too much inventory of completed handsets, the demand for the Company’s products could decline sharply, which could adversely affect the Company’s revenues and results of operations.

The Company’s gross margin, operating margin and net income are highly dependent on the level of revenue, average selling prices and capacity utilization that the Company experiences. A decline in average selling prices (“ASPs”) could adversely affect the Company’s revenues, gross margins and results of operations unless the Company is able to sell more units, reduce its costs, introduce new products with higher ASPs or some combination thereof. Semiconductor manufacturing is a capital-intensive business resulting in high fixed costs. If the Company is unable to utilize its installed wafer fabrication or test capacity at a high level, the costs associated with these facilities and equipment would not be fully absorbed, resulting in higher average unit costs and lower profit margins.

The Company has invested in certain auction rate securities that may not be accessible for more than 12 months and these auction rate securities may experience an other than temporary decline in value, which would adversely affect the Company’s income. At June 30, 2013, the Company held $4.7 million in principal of auction rate notes secured by student loans with a fair value of $4.2 million. As of June 30, 2013, all of these auction rate securities have failed to auction successfully due to sell orders exceeding buy orders. The Company has recorded a $315,000 net of tax ($484,000 pre-tax) temporary impairment of these securities to other comprehensive income, a component of shareholders’ equity. If it is determined that the fair value of these securities is other than temporarily impaired, the Company would record a loss, which could be material, in its statement of operations in the period such other than temporary decline in fair value is determined. For additional information regarding the Company’s investments, see Note 1 of Notes to Condensed Consolidated Financial Statements.

The Company faces various risks associated with the trend toward increased shareholder activism. In 2008, the Company became engaged in a proxy contest with a large shareholder. This dispute led to a significant increase in operating expenses which appreciably reduced the Company’s operating profit and net income. Although this dispute was resolved, the Company could become engaged in another proxy contest in the future. Another proxy contest would require significant additional management time and increased operating expenses, which could adversely affect the Company’s profitability and cash flows.

The semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights. To the extent that the Company becomes involved in such intellectual property litigation, it could result in substantial costs and diversion of resources to the Company and could have a material adverse effect on the Company’s financial condition, results of operation or cash flows. In the event of an adverse ruling in any intellectual property litigation that might arise in the future, the Company might be required to discontinue the use of certain processes or designs, cease the manufacture, use and sale of infringing products, expend significant resources to develop non-infringing technology or obtain licenses to the infringing technology. There can be no assurance, however, that under such circumstances, a license would be available under reasonable terms or at all. In the event of a successful claim against the Company and the Company’s failure to develop or license substitute technology on commercially reasonable terms, the Company’s financial condition, results of operations or cash flows could be adversely affected.

The complexity of the Company’s products may lead to errors or defects, which could subject the Company to significant costs or damages and adversely affect market acceptance of its products. Although the Company’s customers and suppliers rigorously test its products, these products may contain undetected errors, weaknesses or defects. If any of the Company’s products contain production defects, reliability, quality or compatibility problems that are significant, the Company’s reputation may be damaged and customers may be reluctant to continue to buy its products. This could adversely affect the Company’s ability to retain and attract new customers. In addition, these defects could interrupt or delay sales of affected products, which could adversely affect the Company’s results of operations.

33

If defects are discovered after commencement of commercial production, the Company may be required to incur significant costs to resolve the problems. This could result in significant additional development costs and the diversion of technical and other resources from other development efforts. The Company could also incur significant costs to repair or replace defective products or may agree to be liable for certain damages incurred. These costs or damages could have a material adverse effect on the Company’s financial condition and results of operations.

The Company will continue to expend substantial resources developing new products, applications or markets and may never achieve the sales volume that it anticipates for these products, which may limit the Company’s future growth and harm its results of operations. The Company’s future success will depend in part upon the success of new products. The Company has in the past, and will likely in the future, expend substantial resources in developing new and additional products for new applications and markets. The Company may experience unforeseen difficulties and delays in developing these products and experience defects upon volume production and broad deployment. The markets the Company enters will likely be highly competitive and competitors may have substantially more experience in these markets. The Company’s success will depend on the growth of the markets it enters, the competitiveness of its products and its ability to increase market share in these markets. If the Company enters markets that do not achieve or sustain the growth it anticipates, or if the Company’s products are not competitive, it may not achieve volume sales, which may limit the Company’s future growth and would harm its results of operations.

If the Company is unable to convert a significant portion of its design wins into revenue, the Company’s business, financial condition and results of operations could be materially and adversely impacted. The Company has secured a number of design wins for new and existing products. Such design wins are necessary for revenue growth. However, many of the Company’s design wins may never generate revenues if end-customer projects are unsuccessful in the marketplace or the end-customer terminates the project, which may occur for a variety of reasons. Mergers and consolidations among customers may lead to termination of certain projects before the associated design win generates revenue. If design wins do generate revenue, the time lag between the design win and meaningful revenue is typically from six months to greater than eighteen months. If the Company fails to convert a significant portion of its design wins into substantial revenue, the Company’s business, financial condition and results of operations could be materially and adversely impacted.

If the Company’s distributors or sales representatives stop selling or fail to successfully promote its products, the Company’s business, financial condition and results of operations could be adversely impacted. Micrel sells many of its products through sales representatives and distributors. The Company’s non-exclusive distributors and sales representatives may carry its competitors’ products, which could adversely impact or limit sales of the Company’s products. Additionally, they could reduce or discontinue sales of the Company’s products or may not devote the resources necessary to adequately sell the Company’s products. The Company’s agreements with its sell-through distributors contain limited provisions for return of products, including stock rotations whereby distributors may return a percentage of their purchases based upon a percentage of their most recent three months of shipments. In addition, in certain circumstances upon termination of the distributor relationship, distributors may return some or all of their prior purchases. The loss of business from any of the Company’s significant distributors or the delay of significant orders from any of them could materially and adversely harm the Company’s business, financial conditions and results of operations.

In addition, the Company depends on the continued viability and financial resources of these distributors and sales representatives, some of which are small organizations with limited working capital. In turn, these distributors and sales representatives are subject to general economic and semiconductor industry conditions. If some or all of the Company’s distributors and sales representatives experience financial difficulties, do not accurately forecast end market demand, do not properly manage inventory levels, or otherwise become unable or unwilling to promote and sell the Company’s products or deliver the Company’s products in a timely manner, its business, financial condition and results of operations could be adversely impacted.

The Company manufactures most of its semiconductors at its San Jose, California fabrication facilities. The Company’s existing wafer fabrication facility, located in Northern California, may be subject to natural disasters such as earthquakes. A significant natural disaster, such as an earthquake or prolonged drought, could have a material adverse impact on the Company’s business, financial condition and operating results. Furthermore, manufacturing semiconductors requires manufacturing tools that are unique to each product being produced. If one of these unique manufacturing tools was damaged or destroyed, the Company’s ability to manufacture the related product would be impaired and its business would suffer until the tool was repaired or replaced. Additionally, the fabrication of ICs is a highly complex and precise process. Small impurities, contaminants in the manufacturing environment, difficulties in the fabrication process, defects in the masks used to print circuits on a wafer, manufacturing equipment failures and wafer breakage or other factors can cause a substantial percentage of wafers to be rejected or numerous die on each wafer to be nonfunctional. The Company maintains approximately two to three months of inventory that has completed the wafer fabrication manufacturing process. This inventory is generally located offshore at third party subcontractors but may not be sufficient to fully mitigate the adverse impact from a disruption to the Company’s San Jose wafer fabrication activity arising from a natural disaster such as an earthquake.

The Company may be subject to disruptions or failures in information technology systems and network infrastructures that could have a material adverse effect on its business and financial condition. The Company relies on the efficient and uninterrupted operation of complex information technology systems and network infrastructures to operate its business. A disruption, infiltration or failure of the Company’s information technology systems as a result of software or hardware malfunctions, system implementations or upgrades, computer viruses, third-party security breaches, employee error, theft or misuse, malfeasance, power disruptions, natural disasters or accidents could cause breaches of data security, loss of intellectual property and critical data and the release and misappropriation of sensitive competitive information and partner, customer and employee personal data. Any of these events could harm the Company’s competitive position, result in a loss of customer confidence, cause the Company to incur significant costs to remedy any damages and ultimately materially adversely affect its business and financial condition.

While the Company has implemented a number of protective measures, including firewalls, antivirus, patches, data encryption, log monitors, routine back-ups with offsite retention of storage media, system audits, data partitioning, routine password modifications and disaster recovery procedures, such measures may not be adequate or implemented properly to prevent or fully address the adverse effect of such events. In addition, the Company’s third-party subcontractors, including its test and assembly houses and distributors, have access to certain portions of the Company’s and its customers’ and partners’ sensitive data. In the event that these subcontractors do not properly safeguard such data, security breaches and loss of data could result. Any such loss of data by its third-party subcontractors could have a material adverse effect on the Company’s business and financial condition.

The Company’s results of operations could vary as a result of the methods, estimations and judgments used in applying its accounting policies. The methods, estimates and judgments used by the Company in applying its accounting policies have a significant impact on its results of operations. Such methods, estimates and judgments are, by their nature, subject to substantial risks, uncertainties, assumptions and changes in rulemaking by the regulatory bodies, and factors may arise over time that lead the Company to change its methods, estimates, and judgments. Changes in those methods, estimates and judgments could significantly impact the Company’s results of operations.

Changes in tax laws could adversely affect the Company’s results of operations. The Company is subject to income taxes in the United States and in various foreign jurisdictions. Significant judgment is required in determining the Company’s worldwide tax liabilities. The Company believes that it complies with applicable tax law. However, if the governing tax authorities have a different interpretation of the applicable law or if there is a change in tax law, the Company’s financial condition and results of operations may be adversely affected.

The integration of previous and potential future acquisitions that the Company may pursue involves a number of risks. If the Company is unable to address and resolve these risks successfully, such integrations or acquisitions could disrupt its business. For example, in April 2012 the Company acquired PhaseLink which has been integrated with the Company’s business. In addition, the Company may in the future acquire other businesses, products or technologies to expand its product offerings and capabilities, customer base and business. Any of these transactions could be material to the Company’s financial condition and results of operations. The anticipated benefits of these acquisitions may never materialize. In addition, the process of integrating acquired businesses, products or technologies may create unforeseen operating difficulties and expenditures. Some of the areas where the Company may face acquisition-related risks include:

• diversion of management time and potential business disruptions;

• expenses, distractions and potential claims resulting from acquisitions, whether or not they are completed;

• retaining and integrating employees from any businesses that the Company may acquire;

• issuance of dilutive equity securities or incurrence of debt;

• integrating various accounting, management, information, human resource and other systems to permit effective management;

• incurring possible write-offs, impairment charges, contingent liabilities, amortization expense or write-offs of goodwill;

• difficulties integrating and supporting acquired products or technologies;

• unexpected capital expenditure requirements;

• insufficient revenues to offset increased expenses associated with the acquisition;

• opportunity costs associated with committing capital to such acquisitions; and

• acquisition-related litigation.

Foreign acquisitions involve risks in addition to those mentioned above, including those related to integration of operations across different cultures and languages, currency risks and the particular economic, political and regulatory risks associated with specific countries. The Company may not be able to address these risks successfully, or at all, without incurring significant costs, delays or other operating problems. The Company’s inability to address successfully such risks could disrupt its business, which could have a material adverse effect on the Company’s financial condition and results of operations.
