INTEVAC ANNOUNCES FOURTH QUARTER AND FULL YEAR 2013 FINANCIAL RESULTS

Santa Clara, Calif.—January 29, 2014—Intevac, Inc. (Nasdaq: IVAC) today reported financial results for the quarter and year ended December 31, 2013.

“The limited amount of capital expenditures in both our hard drive media and solar cell manufacturing markets resulted in a difficult year for our Equipment business. However, the long-term growth drivers for both of these markets remain positive,” commented Wendell Blonigan, president and chief executive officer of Intevac. “In our Photonics business, we completed the final phase of our Apache camera development program and began shipping production units in late December. We expect this program to drive significant Photonics revenue growth in 2014.

“Over the course of 2013, the company implemented actions that reduced operating expenses by 25% and cash burn by more than 50% from the prior year. In November, we announced a $30 million stock repurchase plan that allows the company to return capital to our stockholders while retaining the flexibility to effectively manage and grow the business. Our market share and technology leadership position in the hard disk drive media manufacturing market, innovative new equipment products for solar cell manufacturing, a growing Photonics business, reduced operating expenditure levels, and solid balance sheet provide a strong foundation for the future.”

Fourth Quarter 2013 Summary

Net income for the quarter was $1.7 million, or $0.07 per diluted share, and includes a $3.7 million credit for the change in fair value of certain contingent consideration obligations related to an acquisition in a prior year. This compares to a net loss of $42.7 million, or $1.82 per share, in the fourth quarter of 2012, which included a $23.4 million valuation allowance established on certain federal deferred tax assets, $18.4 million in goodwill and intangibles impairment charges, and a $0.7 million credit for the change in fair value of acquisition-related contingent consideration. The non-GAAP net loss was 2.0 million, or $0.08 per share, compared to a non-GAAP net loss $4.2 million or $0.18 per share, for the fourth quarter of 2012.

Revenues were $20.6 million, including $12.8 million of Equipment revenues and Photonics revenues of $7.7 million. Equipment revenues consisted of one 200 Lean system, upgrades, spares and service. Photonics revenues included $3.5 million of research and development contracts. In the fourth quarter of 2012, revenues were $17.5 million, including $9.4 million of Equipment revenues and Photonics revenues of $8.1 million, which included $4.9 million of research and development contracts.

Equipment gross margin was 38.1% compared to 46.0% in the fourth quarter of 2012 as a result of a lower mix of higher-margin upgrades. Photonics gross margin was 36.8% compared to 37.4% in the fourth quarter of 2012, reflecting lower overhead absorption as a result of lower program activity. Consolidated gross margin was 37.6%, compared to 42.0% in the fourth quarter of 2012.

R&D and SG&A expenses were $10.3 million compared to $13.5 million in the fourth quarter of 2012. Total operating expenses were $6.6 million and were net of a $3.7 million credit for the change in fair value of acquisition-related contingent consideration. Total operating expenses in the fourth quarter of 2012 of $31.2 million included $18.4 million in non-cash goodwill and intangibles impairment charges offset in part by a $0.7 million credit for the change in fair value of acquisition-related contingent consideration.

Order backlog totaled $59.9 million on December 31, 2013, compared to $70.7 million on September 28, 2013 and $35.2 million on December 31, 2012. Backlog as of December 31, 2013 includes one 200 Lean system and one Solar system as compared to two 200 Lean systems on September 28, 2013. Backlog as of December 31, 2012 did not include any 200 Lean systems.

The company ended the year with $81.4 million of cash and investments and $124.7 million in tangible book value. The company repurchased $1.7 million in stock during the fourth quarter as part of the Stock Repurchase Program announced in November.

Fiscal Year 2013 Summary

The net loss was $15.7 million, or $0.66 per share, compared to a net loss of $55.3 million, or $2.37 per share, for fiscal 2012. The non-GAAP net loss, which excludes a $3.7 million credit for the change in fair value of acquisition-related contingent consideration, a $0.7 million restructuring charge and a $0.2 million divestiture loss, was $18.5 million or $0.78 per share. This compares to the 2012 non-GAAP net loss of $16.2 million, or $0.69 per share, which excludes a $23.4 million valuation allowance established on certain federal deferred tax assets, $18.4 million in goodwill and intangibles impairment charges, a $3.0 million bad debt charge, a $0.2 million credit for the change in fair value of acquisition-related contingent consideration and a $2.2 million divestiture gain.

Equipment gross margin was 31.0%, compared to 44.9% in 2012, primarily due to the lower level of revenue from upgrades, lower factory absorption, a refurbishment provision for a solar evaluation system, and the lower system margin on the first solar implant ENERGi system recognized for revenue. Photonics gross margin was 32.3% compared to 34.2% in 2012, reflecting lower margins on our technology development programs. Consolidated gross margin was 31.6%, compared to 40.9% in 2012.

The operating loss of $17.8 million includes a $3.7 million credit for the change in fair value of acquisition-related contingent consideration, $0.7 million of restructuring charges and a $0.2 million loss on the sale of our Raman spectroscopy product line. The operating loss of $42.5 million for 2012 included $18.4 million in non-cash goodwill and intangibles impairment charges and a $3.0 million bad debt charge, offset in part by a $2.2 million gain on the sale of our mainframe technology and a $0.2 million credit for the change in fair value of acquisition-related contingent consideration.
