QuickLogic Announces Fourth Quarter and Fiscal 2009 Results —

Fourth Quarter New Product Revenue Up 50% Sequentially

SUNNYVALE, Calif. — February 9, 2010 — QuickLogic Corporation (NASDAQ: QUIK), the lowest power programmable semiconductor solutions leader, today announced the financial results for its fourth quarter and fiscal year ended January 3, 2010.

Total revenue for the fourth quarter of 2009 was $4.3 million, up 28% from the third quarter of 2009 and down 28% from the fourth quarter of 2008. The sequential increase of revenue is consistent with the revenue guidance given during the Company’s October 27, 2009, third quarter earnings call. During the fourth quarter, new product revenue increased about 50% to $2.0 million from $1.4 million in the third quarter of 2009. This sequential increase in new product revenue accounted for roughly half of the total revenue in the fourth quarter.

Under generally accepted accounting principles (GAAP), the net loss for the fourth quarter of 2009 was $1.9 million, or $0.06 per share, compared with a net loss of $3.0 million, or $0.10 per share, in the third quarter of 2009 and a net loss of $2.6 million, or $0.09 per share, in the fourth quarter of 2008. Non-GAAP net loss for the fourth quarter of 2009 was $1.3 million, or $0.04 per share, compared with a non-GAAP net loss of $1.9 million, or $0.06 per share, in the third quarter of 2009 and a non-GAAP net loss of $1.2 million, or $0.04 per share, in the fourth quarter of 2008.

Revenue for 2009 was $15.1 million, compared with revenue of $31.9 million in 2008. Under GAAP, the net loss for 2009 was $9.8 million, or $0.32 per share, compared with a net loss of $9.4 million, or $0.32 per share, in 2008. Non-GAAP net loss for 2009 was $7.1 million, or $0.23 per share, compared with a non-GAAP net loss of $3.0 million, or $0.10 per share, in 2008.

Non-GAAP Financial Measures

QuickLogic reports financial information in accordance with GAAP, but believes that non-GAAP financial measures are helpful in evaluating its operating results and comparing its performance to comparable companies. Accordingly, the Company excludes charges related to stock-based compensation, restructuring, the write-down of the Company’s investment in Tower Semiconductor Ltd. and the effect of the write-off of long-lived assets in calculating non-GAAP (i) income (loss) from operations, (ii) net income (loss), (iii) net income (loss) per share, and (iv) gross margin percentage. The Company provides this non-GAAP information to enable investors to evaluate its operating results in a manner similar to how the Company analyzes its operating results and to provide consistency and comparability with similar companies in the Company’s industry.

February 9, 2010

Management uses the non-GAAP measures, which exclude gains, losses and other charges that are considered by management to be outside of the Company’s core operating results, internally to evaluate its operating performance against results in prior periods and its operating plans and forecasts. In addition, the non-GAAP measures are used to plan for the Company’s future periods, and serve as a basis for the allocation of Company resources, management of operations and the measurement of profit-dependent cash and equity compensation paid to employees and executive officers.

Investors should note, however, that the non-GAAP financial measures used by QuickLogic may not be the same non-GAAP financial measures, and may not be calculated in the same manner, as that of other companies. QuickLogic does not itself, nor does it suggest that investors should, consider such non-GAAP financial measures alone or as a substitute for financial information prepared in accordance with GAAP. A reconciliation of GAAP financial measures to non-GAAP financial measures is included in the financial statements portion of this press release. Investors are encouraged to review the related GAAP financial measures and the reconciliation of non-GAAP financial measures with their most directly comparable GAAP financial measures.

Safe Harbor Statement Under The Private Securities Litigation Reform Act of 1995

This press release contains forward-looking statements made by our CEO relating to the revenue generating potential of new products, which is dependent on the market acceptance of our products and the level of customer orders. Actual results could differ materially from the results described in these forward-looking statements. Factors that could cause actual results to differ materially include: delays in the market acceptance of the Company’s new products; the ability to convert design opportunities into customer revenue; our ability to replace revenue from end-of-life products; the level and timing of customer design activity; the market acceptance of our customers’ products; the risk that new orders may not result in future revenue; our ability to introduce and produce new products based on advanced wafer technology on a timely basis; our ability to adequately market the low power, competitive pricing and short time-to-market of our new products; intense competition, including the introduction of new products by competitors; our ability to hire and retain qualified personnel; changes in product demand or supply; capacity constraints; and general economic conditions. These factors and others are described in more detail in the Company’s public reports filed with the Securities and Exchange Commission, including the risks discussed in the “Risk Factors” section in the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and in the Company’s prior press releases.
