TESSERA TECHNOLOGIES ANNOUNCES FIRST QUARTER 2014 RESULTS

COMPANY ACHIEVES $33.4 MILLION IN NET INCOME FROM CONTINUING OPERATIONS

San Jose, Calif., May 6, 2014 – Tessera Technologies, Inc. (NASDAQ: TSRA) (the “Company” or “we”) today announced financial results for the first quarter of 2014. Total revenue from continuing operations for the first quarter of 2014 was $88.3 million. Net income from continuing operations for the first quarter of 2014 was $33.4 million, or $0.62 per diluted share. Non-GAAP net income for the first quarter of 2014 was $41.6 million, or $0.76 per diluted share.

“This is a transformational time for the Company and we are very pleased with the progress made during the quarter,” said Tom Lacey, CEO of Tessera Technologies, Inc. “In addition to signing new license agreements with Samsung Electronics, Co. Ltd., we also reached settlements with PTI, ASE, Renesas and Qualcomm. Additionally, our cost reduction efforts over the past several quarters stand out, with SG&A decreasing 31% from a year ago. All of these developments position us for solid earnings in 2014 and provide a foundation on which to build further revenue growth across our technology portfolios.”

First Quarter Results

Revenue from continuing operations was $88.3 million in the first quarter of 2014, compared with revenue from continuing operations of $28.6 million in the first quarter of 2013. The $59.7 million increase was primarily due to greater episodic revenue in the first quarter of 2014 compared with the first quarter of 2013. Episodic revenue totaled $64.9 million in the first quarter of 2014 compared with $6.5 million in the first quarter of 2013.

Operating expenses were $32.6 million in the first quarter of 2014, compared with $46.3 million in the first quarter of 2013, a decrease of $13.7 million. Selling, general and administrative expenses in the first quarter of 2014 decreased by $6.8 million, or 31%, from the first quarter of 2013. Litigation expense in the first quarter of 2014 decreased by $7.0 million, or 50%, from the first quarter of 2013.

Net income from continuing operations for the first quarter of 2014 was $33.4 million, or $0.62 per diluted share, compared with a net loss from continuing operations for the first quarter of 2013 of $11.3 million, or $0.22 per basic share.

Non-GAAP net income for the first quarter of 2014 was $41.6 million or $0.76 per diluted share, compared with a non-GAAP net loss in the first quarter of 2013 of $6.3 million or $0.12 per basic share. Non-GAAP net income/loss from continuing operations is defined as income/loss and operating expenses adjusted for discontinued operations, restructuring and other exit costs, 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.

Discontinued Operations

The net loss from discontinued operations in the first quarter of 2014 totaled $12.5 million, or $0.24 per basic share, compared with a net loss from discontinued operations in the first quarter of 2013 of $33.3 million or $0.64 per basic share.

Recurring and Episodic Revenue

Recurring revenue is defined as revenue from payments made pursuant to a license agreement or other agreement that are scheduled to occur over at least one year of time. Episodic revenue is revenue other than revenue payable over at least one year pursuant to a contract. Episodic revenue includes non-recurring engineering fees, initial license fees, back payments resulting from audits, damages awards from courts or other tribunals, and lump sum settlement payments. Although the royalty revenue reported by the Company’s licensees on a quarterly basis is generally not assured, for ease of reference, the Company refers to these revenues as “recurring revenue”.

Importantly, a source of episodic revenue may become a source of recurring revenue, when, for example, a company settles litigation with the Company by paying a settlement amount and entering into a license agreement that calls for an initial license fee and ongoing royalty payment over several years. In that scenario, the settlement amount would be episodic revenue, as would the initial license fee, and the ongoing royalties would be recurring revenue.

Discontinued Operations

In March of 2013, the Company announced the closure of its camera module assembly facility in Zhuhai, China and the consolidation of its manufacturing capabilities to Taiwan. The Company planned to continue to assemble lens barrels and make limited quantities of camera modules in the Taiwan facility, and rely on partners for high volume manufacturing. In August of 2013, the Company sold a significant portion of its Micro-Optics business based in Charlotte, NC. In January of 2014, the Company announced the cessation of all mems|cam manufacturing operations. This was the last manufacturing operation in the DigitalOptics business. The Company has classified the revenue and expenses related to the Zhuhai facility and the business in Charlotte as discontinued operations starting with the second quarter of 2013, classified the expenses of its Digital Optics business as discontinued operations starting with the first quarter of 2014, and also reclassified results from each of these facilities and businesses to discontinued operations for all prior reporting periods.

Non-GAAP Financial Measures

In addition to disclosing financial results calculated in accordance with U.S. Generally Accepted Accounting Principles (GAAP), the Company’s earnings release contains non-GAAP financial measures adjusted for discontinued operations, either one-time or ongoing non-cash acquired intangibles amortization charges, acquired in-process research and development, all forms of stock-based compensation, impairment charges on long-lived assets and goodwill, restructuring and other related exit costs, and related tax effects. The non-

GAAP financial measures also exclude the effects of FASB Accounting Standards Codification 718, “Stock Compensation” upon the number of diluted shares used in calculating non-GAAP earnings per share. Management believes that the non-GAAP measures used in this release provide investors with important perspectives into the Company’s ongoing business performance. The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations to those financial statements should be carefully evaluated. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. All financial data is presented on a GAAP basis except where the Company indicates its presentation is on a non-GAAP basis.

Set forth below are reconciliations of non-GAAP net income (loss) to the Company’s reported GAAP net income (loss).
