Photronics Reports First Quarter Fiscal 2017 Results

BROOKFIELD, CT—(Marketwired – February 15, 2017) —

• First quarter sales were $109.8 million, up 2% sequentially on improved IC sales

• Net income attributable to Photronics, Inc. shareholders was $1.9 million ($0.03 per diluted share)

• Net cash¹ improved to $264 million, providing additional financial strength and flexibility to fund growth

• Plan to break ground on new, state-of-the-art IC photomask facility in China by the end of February

• Second quarter 2017 guidance: sales between $105 and $115 million; diluted EPS between $0.01 and $0.07

Photronics, Inc. (NASDAQ:PLAB), a worldwide leader in supplying innovative imaging technology solutions for the global electronics industry, today reported financial results for fiscal 2017 first quarter ended January 29, 2017.

First quarter sales were $109.8 million, up 2% sequentially and down 15% compared with last year. Sales of integrated circuits (IC) photomasks were $86.4 million, an improvement of 5% sequentially and down 13% compared with last year, while sales of flat panel display (FPD) photomasks were $23.4 million, down 7% sequentially and 23% compared with last year.

Net income attributable to Photronics, Inc. shareholders was $1.9 million ($0.03 per diluted share), compared with $21.0 million ($0.28 per diluted share), for the first quarter of 2016, which included a non-recurring net gain of $8.8 million ($0.11 per diluted share); and $5.3 million ($0.08 per diluted share) for the fourth quarter of 2016, which included a non-recurring tax benefit of $1.8 million ($0.03 per diluted share).

"We achieved improved sales compared with the fourth quarter of 2016 as an increase in IC sales was partially offset by lower FPD demand,” said Peter Kirlin, chief executive officer. “IC sales were up, despite seasonal headwinds. FPD was lower as growth in high-end was more than offset by a decline in mainstream as customers focused on supporting current production, which limited new product releases. With the top line improvement, we achieved higher operating income and cash from operations through continued cost management and financial discipline. Progress continues on our two strategic investments this year, with ground breaking scheduled to take place for our China IC facility by the end of February, and we expect to receive new FPD tools soon, with the installation to begin in the third quarter."

Second Quarter 2017 Guidance

Kirlin continued, “Looking ahead to the second quarter, we anticipate improved mainstream IC sales, mixed results in high-end IC, and flat FPD revenues, with orders for new AMOLED displays ramping at quarter end.” For the second quarter of 2017, Photronics expects revenues to be between $105 million and $115 million and net income attributable to Photronics, Inc. shareholders to be between $0.01 and $0.07 per diluted share.

Non-GAAP Financial Measures

Non-GAAP net income attributable to Photronics, Inc. shareholders, non-GAAP earnings per share, and non-GAAP EBITDA are "non-GAAP financial measures" as such term is defined by the Securities and Exchange Commission, and may differ from non-GAAP financial measures used by other companies. The attached financial supplement reconciles Photronics, Inc.'s financial results under GAAP to non-GAAP financial information. Photronics, Inc. believes these non-GAAP financial measures that exclude certain non-cash or non-recurring income or expense items are useful for analysts and investors to evaluate Photronics, Inc.'s future on-going performance because they enable a more meaningful comparison of Photronics, Inc.'s projected earnings and performance with its historical results of prior periods. These non-GAAP metrics are not intended to represent funds available for Photronics, Inc.'s discretionary use and are not intended to represent, or be used as a substitute for, operating income, net income or cash flows from operations data as measured under GAAP. The items excluded from these non-GAAP metrics, but included in the calculation of their closest GAAP equivalent, are significant components of the condensed consolidated statements of income and must be considered in performing a comprehensive assessment of overall financial performance. Non-GAAP financial information is adjusted for the following items:

· Non-recurring tax benefit in fiscal 2016 related to the recognition of certain tax benefits in Taiwan that were determined to be realizable in filings for future tax periods

· Non-recurring net gain on sale of investment in fiscal 2016

· Interest expense, income tax expense/(benefit), depreciation and amortization, and other items are added to GAAP net income to derive non-GAAP EBITDA

Note:

1. Net cash defined as cash and cash equivalents less long-term borrowings (including current portion), as reported in accordance with GAAP.
