SAN JOSE, Calif.—(BUSINESS WIRE)—Tessera Technologies, Inc. (NASDAQ: TSRA) (the “Company” or “we”) today announced financial results for the fourth quarter and full year ending Dec. 31, 2014. Total revenue from continuing operations for the fourth quarter of 2014 was $59.9 million, at the high end of the Company’s guidance range of $58.0 to $60.0 million. GAAP net income for the fourth quarter of 2014 was $37.1 million, or $0.69 per diluted share. Non-GAAP net income for the fourth quarter of 2014 was $33.7 million, or $0.62 per diluted share.

“Fourth quarter results represent a strong finish to a great year,” said Tom Lacey, CEO of Tessera Technologies, Inc. “Our approach to focusing the business on its strengths in technology development and imaging, partnering with customers, and closely managing expenses has yielded a remarkable year for the Company. Most importantly, we are well-positioned to provide innovative solutions to new and existing customers as we grow our recurring revenue base in 2015.”

Fourth Quarter 2014 Results

Revenue from continuing operations was $59.9 million in the fourth quarter of 2014 compared with revenue from continuing operations of $56.3 million in the fourth quarter of 2013. Recurring revenue increased by 69% in the fourth quarter of 2014, from $25.6 million in 2013 to $43.3 million in the fourth quarter of 2014. Episodic revenue, which fluctuates from quarter to quarter, totaled $16.6 million in the fourth quarter of 2014 compared with $30.8 million in the fourth quarter of 2013.

Operating expenses from continuing operations were $13.0 million in the fourth quarter of 2014, compared with $39.3 million in the fourth quarter of 2013, a decrease of $26.3 million. Operating expenses in the fourth quarter of 2014 include a gain of $11.9 million on the sale of long-lived assets to Shenzhen O-Film Tech Co., LTD. in a transaction that closed in December 2014. Litigation expense decreased by $14.1 million, or 87%, from the fourth quarter of 2013, as the Company had significantly fewer legal proceedings outstanding in the fourth quarter of 2014 as compared with 2013.

Net income from continuing operations for the fourth quarter of 2014 was $36.3 million, or $0.68 per diluted share, compared with net income from continuing operations for the fourth quarter of 2013 of $7.0 million, or $0.13 per diluted share.

Non-GAAP net income from continuing operations for the fourth quarter of 2014 was $33.7 million, or $0.62 per diluted share, compared with non-GAAP net income from continuing operations in the fourth quarter of 2013 of $15.2 million, or $0.27 per diluted share. Non-GAAP net income from continuing operations is defined as income and operating expenses 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, gain on sale of patents, restructuring and other related exit costs, and related tax effects.

Year ended December 31, 2014

Total revenue from continuing operations was $278.8 million for the year ended Dec. 31, 2014, an increase of $110.0 million or approximately 65% from the year ended Dec. 31, 2013. Total recurring revenue for the full year 2014 was $149.8 million as compared with $103.1 million for the full year 2013. GAAP operating expenses totaled $113.1 million as compared to $175.1 million in the year ended Dec. 31, 2013, a decrease of $62.0 million or 35%.

Non-GAAP net income from continuing operations was $123.3 million or $2.26 per diluted share.

Discontinued Operations

Net income from discontinued operations in the fourth quarter of 2014 totaled $0.8 million, or $0.01 per diluted share, compared with a net loss from discontinued operations in the fourth quarter of 2013 of $61.2 million, or $(1.14) per basic share. The net loss from discontinued operations in the fourth quarter of 2013 included significant reserves and impairment charges resulting from our decision to discontinue our mems|cam manufacturing operations which was announced in January 2014.

Balance Sheet

Total current assets were $475.5 million as of Dec. 31, 2014, an increase of $83.2 million from Dec. 31, 2013. Cash, cash equivalents and short-term investments were $434.4 million at 2014 year end, an increase of $74.8 million from year end 2013.

Forward-looking statements involve risks and uncertainties that could cause actual results to differ significantly from those projected, particularly with respect to the Company’s financial results and guidance and the Company’s growth prospects.

You are cautioned not to place undue reliance on the forward-looking statements, which speak only as of the date of this release. The Company’s filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the year ended Dec. 31, 2013, and its Quarterly Report on Form 10-Q for the quarter ended Sept. 30, 2014, include more information about factors that could affect the Company’s financial results.

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, gain on sale of patents, 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) and non-GAAP earnings per share to GAAP earnings per share guidance for the first quarter of 2015.
