MILPITAS, Calif., Feb. 05, 2019 (GLOBE NEWSWIRE) -- Nanometrics Incorporated (NASDAQ: NANO), a leading provider of advanced process control systems, today announced financial results for its fourth quarter and full year ended December 29, 2018.
Fourth Quarter and Full Year 2018 Highlights:
- Record Revenues for the Year, Outpacing Industry Growth. Record revenues of $324.5 million for the year, an increase of 25% over 2017, well outpaced the growth of the overall wafer fab equipment (WFE) industry, driven by over 60% growth in product sales to the memory market. Along with robust conditions in the memory industry and tool-of-record positions with each of the world’s leading semiconductor companies, the company’s outperformance was bolstered by significant competitive wins and increasing market share. In the fourth quarter, foundry, IDM and other device sales rebounded more than 50% over Q3, setting the stage for a significant increase in sales expected from these markets for the forthcoming year.
- Growth in Earnings Significantly Greater than Revenue Growth, with Record Free Cash Flow. In fiscal 2018, the company increased both gross and operating margins by approximately four percentage points year-over-year, which along with the strong growth in revenues, drove new annual records in operating income, net income, and free cash flow. The company grew earnings significantly faster than revenues, with earnings per share approximately doubling year-over-year, compared to 25% revenue growth. The company reported $103.3 million in cash flow from operating activities, and after capital expenditures of $7.5 million, generated free cash flow of $95.8 million, or 30% of revenues, for fiscal 2018.
- Completed Acquisition of 4D Technology. Nanometrics announced the acquisition of 4D Technology on October 29th and closed the transaction on November 15th. 4D expands the company’s served markets into the scientific research, aerospace, industrial, and optics manufacturing markets. For the partial quarter, 4D contributed $2.1 million in revenues and was accretive to earnings per share.

A reconciliation between GAAP operating results and non-GAAP operating results is provided following the financial statements that are part of this release and on the investor page of Nanometrics' website. Non-GAAP results exclude the impact of amortization of acquired intangibles, severance costs, executive transition and search costs and certain discrete tax items.
“I am pleased to announce strong results for the fourth quarter, which exceeded our prior forecast, even before the inclusion of 4D for a portion of the period,” commented Dr. Pierre-Yves Lesaicherre, president and chief executive officer of Nanometrics. “Our record revenues for the year and 25% growth over 2017 are indicative of the robust memory spending environment early in the year, the strength of our customer positions, and the meaningful new competitive wins announced in both 3D-NAND and DRAM. As expected, the robust conditions in the memory market began to slow down in the second half, and particularly in the fourth quarter. At the same time, we witnessed a significant increase in activity with our foundry, IDM and other device customers late in the year, with second-half product sales more than doubling over the first half. For the full year, 2018 set new records for the company, and was the fifth straight year of double-digit revenue growth, expanding gross and operating margins, and increasing earnings per share.
“As we look to a slowing memory market entering 2019, we have seen a moderation to our prior sales forecast for the first half of the year. With our current visibility, we expect improvement in memory market conditions to commence in the second half of the year. Our outlook today is for strong growth in sales to the foundry and logic segment in 2019, as well as revenue contribution from 4D in the $15 to $20 million range. Continued growth in our materials characterization and service businesses will also help to offset the expected declines in memory spending in 2019.” Dr. Lesaicherre concluded, “While navigating through this period of significantly curtailed plans for memory capital spending, we will continue our R&D investments in support of new products that will drive future growth and outperformance for Nanometrics, while continuing to deliver solid margins, profits and free cash flows.”

Conference Call Details
A conference call to discuss fourth quarter 2018 results will be held today at 4:30 p.m. EST (1:30 p.m. PST). To participate in the conference call, the dial-in numbers are (877) 374-4041 for domestic callers and (253) 237-1156 for international callers. The conference ID is 5877517. A live and recorded webcast and supplemental financial information will be made available on the investor page of the Nanometrics website at www.nanometrics.com.
Use of Non-GAAP Financial Information
The non-GAAP gross profit, gross margin, operating income, operating income margin, net income, net income per share, which exclude certain expenses, charges and special items, and free cash flow, were not prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP). Management uses non-GAAP financial results, which exclude amortization of acquired intangibles assets, acquisition-related charges, severance costs, executive transition and search costs, gain on disposal of property, certain discrete tax items and other discrete adjustments, to evaluate the company’s ongoing performance and to enable comparison to other periods that did not include these items. The company believes the presentation of non-GAAP results is useful to investors for analyzing ongoing business trends, comparing performance to prior periods, and enhancing the investor’s ability to view the company’s results from management’s perspective; however, investors are cautioned that other companies may calculate these measures differently than Nanometrics does, which would limit the usefulness of these financial measures. A table presenting a reconciliation of GAAP results to non-GAAP results is included at the end of this press release and is available on the investor page of the Nanometrics website at www.nanometrics.com.
