TESSERA TECHNOLOGIES ANNOUNCES SECOND QUARTER 2013 RESULTS

- Quarterly Dividend Declared -

San Jose, Calif.- July 31, 2013 – Tessera Technologies, Inc. (NASDAQ: TSRA) (the “Company” or “we”) announced its results for the second quarter ended June 30, 2013. Total revenue from combined continuing operations and discontinued operations for the second quarter of 2013 was $49.3 million, of which $46.6 million was from continuing operations. Generally accepted accounting principles (GAAP) net loss from continuing operations for the second quarter of 2013 was $24.0 million, or $0.45 per basic share. Non-GAAP net loss for the second quarter of 2013 was $12.3 million or $0.23 per basic share. Non-GAAP net loss excludes non-recurring charges of $5.9 million, $5.2 million in amortization of acquired intangibles, and $5.0 million of stock based compensation and the related tax effect of such items of $4.4 million.

Year over Year Comparison

In the second quarter of 2013, total revenue from continuing operations was $46.6 million. Compared with the Company’s second quarter of 2012 revenue from continuing operations of $58.3 million, this is a decrease in total revenue from continuing operations of $11.7 million. The decline was due to a decrease in the Intellectual Property business revenue of $10.1 million and a decrease in the DigitalOptics (DOC) revenue of $1.6 million.

The Company’s Intellectual Property revenue for the second quarter of 2013 was $42.9 million, compared to $53.0 million in the year ago quarter. The $10.1 million decrease was due to the absence of royalty revenue from Micron Technology, Inc., whose license agreement expired in May of 2012, and Powertech Technology Inc. (PTI), who last made a payment in the third quarter of 2012. Second quarter of 2013 Intellectual Property revenue included $18.9 million in episodic revenue.

The Company’s DOC revenue from continuing operations for the second quarter of 2013 was $3.7 million, compared to $5.3 million in the year ago quarter. The $1.6 million decrease was due to lower revenues from the Company’s image enhancement technologies.

Non-GAAP net loss for the second quarter of 2013 was $12.3 million or $0.23 per basic share. Non-GAAP net income/loss 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.

“The second quarter of 2013 was a positive one for the Company in a few areas,” stated Thomas Lacey, interim CEO of Tessera Technologies, Inc. “First, we had our first quarter of increased recurring revenue from the two SK hynix agreements announced in early January, which, as we have said, will generate significantly higher recurring revenue from SK hynix on an annual basis. Second, we received nearly $19 million of episodic revenue, which, as our stockholders know, will be put towards the special dividend we will declare in next year’s second quarter. And, we announced Samsung had licensed DOC’s Face Detection and Face Tracking software technology for use in its Samsung Galaxy S4s, the revenue impact of which we will start to see in the third quarter as we recognize royalty revenue one quarter in arrears.

“For the remainder of 2013, we have three key priorities; relicense DRAM manufacturers to our innovative IP patent portfolios, rationalize our DOC strategy and determine the best strategic alternative for this business, and stabilize and streamline our Company’s overall infrastructure and operations. We have already taken, significant steps and continue to make progress on all fronts. I look forward to updating our stockholders on our progress in the coming months.”

Discontinued Operations

Beginning in the second quarter of 2013, the Company has classified financial results for its DigitalOptics facilities in Zhuhai, China and Charlotte, North Carolina as discontinued operations. Refer to the discussion of discontinued operations below for further details. Second quarter of 2013 discontinued operations included total revenue of $2.7 million, GAAP operating expenses of $7.8 million, and a tax benefit of $13.3 million. This compares with total revenue from discontinued operations of $2.5 million, GAAP operating expenses of $20.7 million and tax provision of $0.9 million in the first quarter of 2013. The expense decrease quarter over quarter reflects the Company’s winding down of operations in its facility in Zhuhai during the second quarter as well as higher restructuring and impairment charges incurred in the first quarter related to the Zhuhai operation. The increase in tax benefit attributable to discontinued operations in the second quarter is a reflection of the allocation of total tax benefit between continuing and discontinued operations.

Balance Sheet

Total current assets were $417.9 million at June 30, 2013, a decrease of $25.8 million from March 31, 2013. Cash, cash equivalents and short-term investments were $380.5 million at June 30, 2013, a decrease of $22.2 million from March 31, 2013. The quarter over quarter decrease resulted from a combination of the cash loss from operations of $13.7 million, $21.4 million of dividend payments, $1.6 million net capital expenditures, and $1.7 million of intellectual property purchases, offset by $16.8 million cash proceeds from stock option exercises.

Dividends

On May 31, 2013, $16.1 million was paid to stockholders of record as of May 23, 2013, for a special cash dividend of $0.30 per common 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 quarterly 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 determined its DigitalOptics business was to be restructured and announced its plans to close its facility in Zhuhai, China and announced the consolidation of its manufacturing capabilities to Taiwan. The Company will continue to assemble lens barrels and make limited quantities camera modules in the Taiwan facility, but will increasingly rely on partners for high volume manufacturing. In the fourth quarter of 2012, the Company announced that its business in Charlotte, North Carolina was no longer part of its long-term strategy, and that it was exploring strategic alternatives for this business. In the second quarter of 2013, the Company actively pursued a sale of this business. The Company has classified the revenue and expenses related to the Zhuhai facility and the business in Charlotte as discontinued operations starting with this second quarter of 2013, and also reclassified results from those facilities 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

6

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.

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