INTEVAC ANNOUNCES FOURTH QUARTER AND FULL YEAR 2018 FINANCIAL RESULTS

Santa Clara, Calif.—January 30, 2019—Intevac, Inc. (Nasdaq: IVAC) today reported financial results for the fiscal fourth quarter and year ended December 29, 2018.

“We were very pleased to finish 2018 on a high note, with year-end backlog of $109 million at the highest level in more than eight years, driven by significant new orders in both Thin-film Equipment (TFE) and Photonics,” commented Wendell Blonigan, president and chief executive officer of Intevac. “The continued technology investments by our hard drive customers helped drive another strong growth year for our HDD business in 2018, and today we have six 200 Lean^® systems in backlog and a continued solid pipeline of process module upgrades. Photonics recently announced a record order for the development of digital night vision systems destined for the ground soldier, which is the largest revenue opportunity in this business’ history. In spite of the pause in the revenue growth trajectory in our TFE growth initiatives, in 2018 we recognized revenue on three ENERGi^® systems for solar ion implantation and witnessed increasing interest in the differentiated decorative coatings enabled by our INTEVAC VERTEX^® system, including transitioning and gradient colors as well as patterned effects for backside cover glass. This progress in our TFE growth initiatives, along with continued strength in HDD and growing momentum for Photonics, gives us increasing confidence for a resumption of revenue growth and profitability in 2019.”

Intevac’s non-GAAP adjusted results exclude where applicable: (1) changes in fair value of contingent consideration liabilities associated with business combinations; and (2) restructuring charges and (3) the reversal of a deferred tax asset valuation allowance. 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.

The Company’s fourth quarter financial results include the reversal of the valuation allowance recorded against the deferred tax assets in Singapore. This reversal resulted in the recognition of a non-cash income tax benefit in the fourth quarter of 2018 of $7.9 million, or $0.34 per diluted share. Non-GAAP net income was $1.9 million, or $0.08 per diluted share, compared to a non-GAAP net loss of $83,000, or $0.00 per diluted share, for the fourth quarter of 2017.

Revenues were $31.6 million, including $23.6 million of TFE revenues and Photonics revenues of $8.0 million. TFE revenues consisted of one 200 Lean HDD system, three ENERGi solar ion implant systems, upgrades, spares and service. Photonics revenues included $2.2 million of research and development contracts. In the fourth quarter of 2017, revenues were $24.8 million, including $17.9 million of TFE revenues which consisted of two 200 Lean HDD systems, upgrades, spares and service and Photonics revenues of $6.9 million, which included $2.7 million of research and development contracts.

TFE gross margin was 30.6% compared to 45.0% in the fourth quarter of 2017 and 40.2% in the third quarter of 2018. The decline from the fourth quarter of 2017 and the third quarter of 2018 reflected the lower margin on the three ENERGi solar ion implant systems.

Photonics gross margin was 42.1% compared to 26.0% in the fourth quarter of 2017 and 35.5% in the third quarter of 2018. The improvement from the fourth quarter of 2017 and the third quarter of 2018 was primarily due to higher revenue levels and favorable product mix. Consolidated gross margin was 33.5%, compared to 39.8% in the fourth quarter of 2017 and 38.5% in the third quarter of 2018.

R&D and SG&A expenses were $8.8 million, compared to $9.7 million in the fourth quarter of 2017 and to $8.6 million in the third quarter of 2018. Lower year-over-year expenses primarily reflects cost control initiatives implemented in the first quarter of 2018.

Order backlog totaled $108.5 million on December 29, 2018, compared to $72.2 million on September 29, 2018 and $64.0 million on December 30, 2017. Backlog at December 29, 2018 included six 200 Lean HDD systems and nine ENERGi solar ion implant systems. Backlog at both September 29, 2018 and December 30, 2017 included three 200 Lean HDD systems and twelve ENERGi solar ion implant systems.

The Company ended the year with $40.3 million of total cash, restricted cash and investments and $88.7 million in tangible book value, defined as total stockholders’ equity less intangible assets.

Consolidated gross margin was 34.4% compared to 40.5% in 2017.
