TESSERA TECHNOLOGIES ANNOUNCES FOURTH QUARTER AND FISCAL YEAR 2012 RESULTS

– Quarterly Dividend Declared –

San Jose, Calif.,- Feb. 7, 2013 – Tessera Technologies, Inc. (NASDAQ: TSRA) (the “Company” or “we”) announced its results for the fourth quarter ended Dec. 31, 2012. Total revenue for the fourth quarter of 2012 was $53.2 million. Generally accepted accounting principles (GAAP) net loss for the fourth quarter of 2012 was $19.6 million, or $0.38 per basic share.

“Fourth quarter of 2012 Intellectual Property revenue of $43.0 million resulted in full year 2012 Intellectual Property revenue of $192.9 million, within our targeted long-term Intellectual Property average annual revenue run rate of $180 million to $200 million,” stated Robert A. Young, president and chief executive officer, Tessera Technologies, Inc. “Historically, our Tessera, Inc. patent portfolio has generated our Intellectual Property royalties. We also have semiconductor related patents and next-generation technologies in our Invensas Corporation patent portfolio, which are key to our broad DRAM re-licensing program. In January of 2013 we announced SK hynix Inc. as the first DRAM maker to take a license to our Invensas Corporation portfolio, which expanded our revenue base. The successful conclusion of the SK hynix deal gives us confidence we are well positioned to maintain our targeted long-term Intellectual Property average annual run-rate revenue.

“Turning to our DigitalOptics segment, we are excited to announce today that John Thode has been appointed president of DigitalOptics Corporation. Thode, a consumer mobile product industry veteran, will be responsible for the Company’s DigitalOptics business, including strategy and operations. In the fourth quarter of 2012 we shipped sample quantities of our MEMS autofocus camera modules to three smartphone Original Equipment Manufacturers (OEMs). We believe our MEMS autofocus camera modules focus faster and require less power than the existing voice coil motor technology currently being used for the autofocus mechanism in smartphone cameras. We are seeing strong demand for our products, with their highly differentiated attributes, and this validates our strategy of investing in this business, which offers a significant growth opportunity in the foreseeable future.”

Fourth Quarter 2012

Total revenue for the fourth quarter of 2012 was $53.2 million, compared to $56.7 million of total revenue in the fourth quarter of the prior year. Intellectual Property segment revenue for the fourth quarter of 2012 was $43.0 million, compared to $49.0 million in the fourth quarter of the prior year. The year-over-year decrease was due primarily to the absence of royalty revenue from Micron Technology, Inc. and Powertech Technology Inc., which was partly offset by the receipt of past production payments of $24.7 million in the fourth quarter of 2012.

DigitalOptics segment revenue for the fourth quarter of 2012 was $10.2 million, compared to $7.7 million in the fourth quarter of the prior year. The increase was due primarily to sales of fixed focus camera modules of $3.8 million that occurred in 2012 but did not occur in 2011, which was partly offset by lower revenues from the Company’s image enhancement technologies and weaker demand for the Company’s Micro-Optics products.

GAAP net loss for the fourth quarter of 2012 was $19.6 million, or $0.38 per basic share, which included non-cash charges of $6.2 million for amortization of acquired intangibles and $3.8 million for stock-based compensation.

Non-GAAP net loss for the fourth quarter of 2012 was $12.8 million or $0.24 per basic share. Non-GAAP net income is defined as income and operating expenses adjusted for acquired intangibles amortization, charges for acquired in-process research and development, stock-based compensation expense, impairment charges on long-lived assets and goodwill, and related tax effects.

Year Ended Dec. 31, 2012

GAAP net loss for the year was $29.3 million, or $0.56 per basic share. Non-GAAP net income for the year was $1.7 million, or $0.03 per diluted share.

Balance Sheet

Cash, cash equivalents and investments were $442.6 million at Dec. 31, 2012, a decrease of $23.3 million from Sept. 30, 2012. In the fourth quarter of 2012, net cash provided by operations was $1.8 million. The Company purchased $20.6 million of property and equipment and $900,000 of intellectual property in the fourth quarter of 2012. On Dec. 13, 2012, $5.2 million was paid to stockholders of record as of Nov. 22, 2012, for the quarterly $0.10 per share of common stock cash dividend.

2013 Company Cost Cutting Efforts

The Company has reviewed its corporate general and administrative (G&A) expense in relation to its two operating businesses and has determined that it is appropriate to take steps to reduce corporate G&A spending in the range of 17% to 21% by the end of year 2013 as compared to 2012. These cost reductions are in addition to the cost-cutting measures announced in November 2012. The Company has determined that the Silent Air Cooling business is not a strategic fit for its ongoing business, and management will be looking at a possible sale of, or other strategic alternatives for this business. In February 2013, the Company announced a salary freeze until the summer, when compensation will be reevaluated.

Quarterly Cash Dividend
