TESSERA TECHNOLOGIES ANNOUNCES FOURTH QUARTER & FULL YEAR 2013 RESULTS

San Jose, Calif., Feb. 5, 2014 – Tessera Technologies, Inc. (NASDAQ: TSRA) (the “Company” or “we”) announced its results for the fourth quarter and full year ended Dec. 31, 2013. Total revenue from continuing operations for the fourth quarter of 2013 was $56.4 million. Generally accepted accounting principles (GAAP) net loss from continuing operations for the fourth quarter of 2013 was $46.2 million, or $0.86 per basic share, and included $45.3 million in impairment charges primarily related to the Company’s previously announced decision to stop its mems|cam^TM manufacturing business. Non-GAAP net income for the fourth quarter of 2013 was $7.7 million or $0.14 per diluted share.

“At Tessera we are laser focused on our core business again and fully expect the Company to return to Non-GAAP profitability based on our recurring revenue alone in 2014 which was bolstered by our recent signing of license agreements with Samsung Electronics, Co Ltd.,” stated Thomas Lacey, CEO of Tessera Technologies, Inc. “Tessera is at a strategic inflection point in its history and is well positioned for future growth. We are excited for the opportunities that lie ahead.”

Year over Year Comparison

Total revenue from continuing operations was $56.4 million in the fourth quarter of 2013, as compared with revenue from continuing operations of $47.6 million in the fourth quarter of 2012, an increase of $8.8 million.

The Company’s Intellectual Property revenue for the fourth quarter of 2013 was $49.1 million, compared to $43.0 million in the year ago quarter. The $6.1 million increase was primarily due to increased royalty revenue from SK hynix, Inc., as compared to the prior year’s fourth quarter, and greater episodic revenue in the fourth quarter of 2013 compared to 2012. Fourth quarter of 2013 Intellectual Property revenue included $30.8 million in episodic revenue compared to $26.5 million in the fourth quarter of 2012.

The Company’s DigitalOptics (DOC) revenue from continuing operations for the fourth quarter of 2013 was $7.2 million, compared to $4.6 million in the year ago quarter. The $2.6 million increase was due to a one-time license fee related to a legacy DOC license agreement, offset by lower product and services revenue in the fourth quarter of 2013 as compared to 2012.

The GAAP net loss from continuing operations for the fourth quarter was $46.2 million, or $0.86 per basic share. The GAAP net loss from continuing operations for the fourth quarter of 2012 was $12.7 million, or $0.24 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.

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 June of 2013, the Company closed its camera module assembly facility in Zhuhai, China and announced 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. 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, 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 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.
