TESSERA TECHNOLOGIES ANNOUNCES SECOND QUARTER 2015 RESULTS

Recurring revenue increases 77% year-over-year to $63.2 million

Earnings per share of $0.49 significantly above guidance range of $0.37-$0.40

Company repurchased $25 million of common stock during the quarter

San Jose, Calif., (BUSINESS WIRE) - Tessera Technologies, Inc. (NASDAQ: TSRA) (the “Company” or “we”) today announced financial results for the second quarter of 2015. Total revenue was $64.2 million, just above the Company’s guidance range of $62 to $64 million. Recurring revenue was $63.2 million, an increase of 77% compared with $35.8 million in the second quarter of 2014. GAAP net income for the second quarter of 2015 was $26.1 million, or $0.49 per diluted share, and non-GAAP net income was $31.5 million, or $0.58 per diluted share.

“This quarter we again delivered terrific results in our core business,” said Tom Lacey, CEO of Tessera Technologies, Inc. “Our customer collaboration strategy continues to bear fruit, as the Invensas team is actively involved with leading manufacturers on xFD and BVA technology. FotoNation followed record first quarter revenue with a similar performance in the second quarter, while also developing new solutions for biometric authentication and the automotive market. I remain confident that the second half of this year will yield further success - particularly as we progress with the commercialization of our advanced packaging technologies and sign new customer agreements for our intellectual property and imaging solutions. This is an exciting time at Tessera.”

Second Quarter 2015 Results

Total revenue was $64.2 million in the second quarter of 2015, a 72% increase compared with revenue of $37.2 million in the second quarter of 2014. The $27.0 million increase was primarily due to new license and settlement agreements that have been signed in the last year and a half.

Operating expenses were $27.4 million in the second quarter of 2015, compared with $36.3 million in the second quarter of 2014, a decrease of $8.9 million, or 25%. Litigation expense in the second quarter of 2015 decreased by $6.7 million, or 66%, from the second quarter of 2014, due to settlements reached during the last year and a half. Research and development (R&D) and selling, general and administrative (SG&A) expenses decreased by a combined $1.9 million, or 9%, compared with the prior year, the result of cost savings initiatives implemented over the past year.

Net income was $26.1 million, or $0.49 per diluted share, compared with net income for the second quarter of 2014 of $3.8 million, or $0.07 per diluted share.

Non-GAAP net income for the second quarter of 2015 was $31.5 million, or $0.58 per diluted share, compared with non-GAAP net income in the second quarter of 2014 of $10.2 million, or $0.19 per diluted share. Non-GAAP net income/loss is defined as income/loss and operating expenses adjusted for discontinued operations, restructuring and other exit costs, acquired intangible asset 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.

Balance Sheet

Total current assets were $479.7 million as of June 30, 2015, an increase of $4.2 million from December 31, 2014.

The decline in cash in the first half of the fiscal year is due to common stock repurchases and the payment of dividends, largely offset by cash generated from operating activities.

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 January of 2014, the Company announced the cessation of all mems|cam manufacturing operations. This was the Company’s last manufacturing operation. The Company has classified the expenses of its DigitalOptics business as discontinued operations starting with the first quarter of 2014, and also reclassified results from this business 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 third quarter of 2015.
