INTEVAC ANNOUNCES SECOND QUARTER 2014 FINANCIAL RESULTS

Santa Clara, Calif.—July 28, 2014—Intevac, Inc. (Nasdaq: IVAC) today reported financial results for the quarter and six months ended June 28, 2014.

“During the second quarter, our Photonics business achieved record levels of both revenue and operating profit and is on track to grow by approximately 30% this year as compared to 2013,” commented Wendell Blonigan, president and chief executive officer of Intevac. “Ramping production for any new product is always a challenge, and our Photonics division demonstrated excellent performance both in ramping the Apache Camera and meeting our customer commitments.

“In our thin film equipment business, we are on track to ship our first protective coating system for touch screen mobile cover glass, as well as our first INTEVAC MATRIX™ PVD system for solar cell manufacturing, within the next few weeks. Each of these deployments demonstrates meaningful progress on our strategy to provide thin film deposition systems to vacuum coating markets adjacent to the hard disk media industry. The hard drive industry is predicting improving demand through the second half of the year, and industry analysts are forecasting annual sequential growth in media units beginning in 2014.”

Intevac’s non-GAAP adjusted results exclude the impact of the following, where applicable: (1) changes in fair value of contingent consideration liabilities associated with business combinations; (2) restructuring charges; and (3) gains or losses on sales of product lines and technology assets. A reconciliation of the GAAP and non-GAAP adjusted results is provided in the financial table included in this release. See also “Use of Non-GAAP Financial Measures” section.

Second Quarter 2014 Summary

The net loss for the quarter was $5.0 million, or $0.21 per share, compared to a net loss of $6.4 million, or $0.27 per share, in the second quarter of 2013. The non-GAAP net loss was $4.9 million or $0.20 per share. This compares to the second quarter 2013 non-GAAP net loss of $6.5 million or $0.27 per share.

Revenues were $14.7 million, including $3.8 million of Equipment revenues and Photonics revenues of $11.0 million. Equipment revenues included upgrades, spares and service. Photonics revenues consisted of $2.7 million of research and development contracts and $8.3 million of product sales. In the second quarter of 2013, revenues were $17.0 million, including $9.2 million of Equipment revenues and Photonics revenues of $7.8 million, which included $3.7 million of research and development contracts.

Equipment gross margin was 8.3% compared to 14.8% in the second quarter of 2013 and 22.2% in the first quarter of 2014. Equipment margins in the second quarter of 2014 were lower due to lower factory absorption as a result of the lower level of revenue. Equipment margins in the second quarter of 2013 reflected a refurbishment reserve recorded for a solar evaluation system as well as the lower margin on the first solar implant ENERGi system recognized for revenue.

Photonics gross margin was 44.7% compared to 31.7% in the second quarter of 2013 and 35.2% in the first quarter of 2014. The improvement from the second quarter of 2013 was driven by the increased mix of higher margin product revenue, improved yields for our low-light sensor, and higher margins on technology development programs. The improvement from the first quarter of 2014 was driven by the increased mix of higher margin products, improved yields offset in part by lower margins on technology development programs. Consolidated gross margin was 35.4%, compared to 22.5% in the second quarter of 2013 and 28.3% in the first quarter of 2014.

Operating expenses of $10.5 million increased 9.7% compared to the first quarter of 2014 as a result of $0.8 million of incremental costs incurred from the proxy contest.

Order backlog totaled $46.4 million on June 28, 2014, compared to $51.9 million on March 29, 2014 and $77.6 million on June 29, 2013. Backlog as of both June 28, 2014 and March 29, 2014 included one Solar system and one PVD touch screen glass coating system and did not include any 200 Lean systems. Backlog as of June 29, 2013 included three 200 Lean systems.

The company ended the quarter with $75.3 million of cash and investments and $116.2 million in tangible book value. The company repurchased $0.4 million in stock during the second quarter as part of the $30 million stock repurchase program announced in November 2013.

First Six Months 2014 Summary

The net loss was $9.5 million, or $0.40 per share, compared to a net loss of $14.7 million, or $0.62 per share, for the first six months of 2013. The non-GAAP net loss was $9.1 million or $0.38 per share. This compares to the first half 2013 non-GAAP net loss of $14.0 million or $0.59 per share.

Revenues were $31.7 million, including $12.8 million of Equipment revenues and Photonics revenues of $18.9 million, compared to revenues of $30.0 million, including $14.5 million of Equipment revenues and Photonics revenues of $15.4 million, for the first six months of 2013.

Equipment gross margin was 18.1%, compared to 17.6% in the first six months of 2013, primarily due to higher margins from systems, lower factory overhead expenses and lower inventory charges. We recognized revenue on one 200 Lean system in the first half of 2014 and did not recognize any revenue on 200 Lean systems in the first half of 2013. Fiscal 2013 Equipment gross margin reflected 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 40.7% compared to 31.0% in the first six months of 2013, reflecting the increased mix of higher margin product shipments, improved yields, higher margins on technology development programs and lower warranty costs. Consolidated gross margin was 31.6%, compared to 24.5% in the first six months of 2013.

Operating expenses were $20.0 million and were down 13.6% from $23.1 million in the first six months of 2013 primarily due to cost reduction activities, offset in part by costs associated with the proxy contest.
