LATTICE SEMICONDUCTOR REPORTS FIRST QUARTER RESULTS

HILLSBORO, Ore.  -  April 25, 2006  -  Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced financial results for the first quarter ended March 2006.

For the first quarter, revenue was $57.5 million, an increase of 12 percent from the $51.3 million reported in the same quarter a year ago and an increase of six percent from the $54.0 million reported last quarter.  Quarterly revenue from PLD products was $46.7 million, or 81 percent of total revenue, and increased six percent sequentially.  Quarterly revenue from FPGA products was $10.8 million, or 19 percent of total revenue, and increased nine percent sequentially. 

Other income for the first quarter was $3.8 million and included a $1.2 million gain related to the extinguishment of outstanding zero coupon convertible notes.

Net loss for the first quarter was $0.8 million ($0.01 per share), a significant improvement compared to a net loss of $10.9 million ($0.10 per share) in the same quarter a year ago and a net loss of $23.0 million ($0.20 per share) in the previous quarter.  The first quarter loss includes charges of $2.8 million for the amortization of intangible assets (currently expected to be substantially eliminated in 2008) and $0.7 million for stock-based compensation expense.  Excluding these charges, the Company posted net income for the first quarter of $2.7 million, or $0.02 per share.  The Company believes exclusion of these charges more closely approximates its ongoing operational performance.

A reconciliation of non-GAAP net income (loss) to GAAP net loss accompanies the financial tables in this earnings release.

“It is gratifying to see that our efforts are starting to show results and we are very pleased that we have returned to profitability on a pro-forma basis. Our significantly improved financial results are due to a combination of strong revenue growth, a rebounding gross margin, and realization of the forecasted operating expense reductions from last quarter’s corporate restructuring,” said Steve Skaggs, President and Chief Executive Officer of Lattice Semiconductor Corporation. “The positive worldwide customer reception of our 130nm FPGA products combined with the recent introduction of our exciting 90nm FPGA families cause us to be optimistic about our future prospects,” added Mr. Skaggs.

First Quarter Business Highlights:

•      Introduced the LatticeSC System Chip FPGA family of high-density devices designed to provide unsurpassed performance and connectivity featuring high-speed I/O, world-class SERDES transceivers, embedded ASIC blocks, and fabricated on leading edge 90nm CMOS technology utilizing 300mm wafers;

•      Introduced the LatticeECP2 FPGA family of second generation, low-cost devices featuring increased logic densities up to 70K LUTs, enhanced DSP capabilities and increased I/O performance. Capabilities added for the first time to this class of devices include pre-engineered 400Mbps DDR2 interface support, configuration bitstream encryption and dual-boot configuration support. This family is also fabricated on leading edge 90nm CMOS technology utilizing 300mm wafers;

•      Expanded the mixed signal Power Manager II family with programmable power management solutions for high-volume applications. These new low-cost devices integrate power supervisors, sequencers and reset generators, and are ideally suited for cost or size-sensitive applications;

•      Added Rochester Electronics as a value added distributor for discontinued products;

•      Reached agreement, in principle, to settle the consolidated class action litigation filed in 2004. The Company expects the entire amount of the settlement to be paid by its insurer.  The settlement amount will not affect Lattice’s current or future financial results.

Business Outlook – June 2006 Quarter:

•      Sequential quarterly revenue growth is expected to be approximately 3%-6%; 

•      Gross margin percentage is expected to be approximately 56%;

•      Total operating expenses are expected to be approximately $34-$35 million, which includes an estimated $1 million of stock-based compensation expense (inclusion of stock-based compensation in operating expenses adds significant uncertainty to our estimates of expenses due to the effect of the volatility in our stock price, which we cannot predict);

•      Intangible asset amortization is expected to be approximately $2.7 million; and

•      Other income is expected to be approximately $2.5 million.

Discussion of Non-GAAP Financial Measures:

Management evaluates and makes operating decisions using various performance measures. In addition to our GAAP results, we also consider adjusted net income (loss), which we refer to as non-GAAP net income (loss). This measure is generally based on the revenues of our products and the costs of those operations, such as cost of revenue, research and development, sales and marketing and general and administrative expenses, that management considers in evaluating our ongoing core operating performance. Non-GAAP net income (loss) consists of net loss excluding amortization of intangible assets, stock-based compensation, and restructuring charges.

Intangible assets relate to assets acquired through acquisitions and consist of technology purchased in connection with the acquisitions. Stock-based compensation charges are related to the adoption of SFAS No. 123(R) effective January 1, 2006, and include expense for items such as stock options granted to employees, purchases under the employee stock purchase plan and deferred stock compensation issued in connection with acquisitions (prior quarters have been reclassified to be consistent with the current quarter presentation). Restructuring charges consist of expenses incurred under our corporate restructuring plan, and include items such as separation packages, costs to vacate space under long-term lease arrangements, cost to write-off an intellectual property license and other related expenses.

Non-GAAP net income (loss) is a supplemental measure of our performance that is not required by and not presented in accordance with GAAP. Moreover, it should not be considered as an alternative to net loss, operating loss or any other performance measure derived in accordance with GAAP, or as an alternative to cash flow from operating activities or as a measure of our liquidity. Investors and potential investors are encouraged to review the reconciliation of non-GAAP financial measures contained within this press release with our net loss, which is

our most directly comparable GAAP financial result. For more information, see the consolidated statements of operations contained in this earnings release.

On April 26, 2006, Lattice will hold a telephone conference call at 5:30 am (Pacific Time) with financial analysts.  Investors may listen to our conference call live via the web at www.lscc.com.  Replays of the call will also be available at www.lscc.com.  On June 14, 2006, we plan to publish a “Business Update Statement” on our website.  Our financial guidance will be limited to the comments on our public quarterly earnings call and these public business outlook statements.  Additionally, during the June 2006 quarter, Lattice plans to participate in an investor conference sponsored by JP Morgan.  Specific presentation dates and times are posted on our website at www.lscc.com.

The foregoing paragraphs contain forward-looking statements that involve estimates, assumptions, risks and uncertainties.  With respect to particular forward-looking statements in the Business Outlook – June 2006 Quarter section of this release, Lattice believes the factors identified below in connection with each such statement could cause actual results to differ materially from the forward-looking statements.

Estimates of future revenue are inherently uncertain due to the high percentage of quarterly “turns” business.  In addition, revenue is affected by such factors as pricing pressures, competitive actions, the demand for our products, and the ability to supply products to customers in a timely manner.  Actual gross margin percentage and operating expenses could vary from the estimates contained herein on the basis of, among other things, changes in revenue levels, product pricing, changes in wafer, assembly and test costs, variations in manufacturing yields, and changes in stock-based compensation charges due to stock price changes.

In addition to the foregoing, other factors that may cause actual results to differ materially from the forward-looking statements herein include the Securities and Exchange Commission’s informal inquiry and any resulting actions, our ability to successfully conclude the settlement of our pending securities class action litigation, the Company’s dependencies on its silicon wafer suppliers, technological and product development risks, and the other risks that are described from time to time in our filings with the Securities and Exchange Commission. The Company does not intend to update or revise any forward-looking statements, whether as a result of events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.
