Nanometrics Reports Second Quarter 2018 Financial Results

Record Revenues and Earnings; Strong Outlook Continues for FY 2018

MILPITAS, Calif., July 31, 2018 — Nanometrics Incorporated (NASDAQ: NANO), a leading provider of advanced process control systems, today announced financial results for its second quarter ended June 30, 2018.

Second Quarter 2018 Highlights:

• Record Revenue and Earnings.  The positive business environment for memory capital spending, as well as the company’s strong positions with key customers in the memory market, drove revenues to a new quarterly record of $88.6 million, up 8% from the first quarter, and up 38% from the second quarter of 2017. With gross margins continuing to deliver ahead of our financial model targets, and further improvements made to our tax rate, earnings per share also set a new quarterly record.

• Continued Strong Adoption of Atlas® III. The company’s flagship automated optical critical dimension (“OCD”) system, the Atlas III, was qualified for high-volume manufacturing at a fifth leading 3D-NAND customer during the second quarter. With this qualification, the Atlas III has now been adopted into volume production at each of the five major 3D-NAND manufacturers, and at both of the largest DRAM manufacturers. Demonstrating the Atlas III’s market leadership for OCD metrology for three-dimensional device structures, the company celebrated its 100^th Atlas III shipment earlier this month.

• Strong Free Cash Flow Generation. The second quarter was another strong period of free cash flow generation, following record cash flow performance in the first quarter. Year-to-date, the company has reported $59.0 million in cash flow from operating activities, and after capital expenditures of $1.8 million, generated first-half 2018 free cash flow of $57.2 million, or 33% of first-half revenues. Total cash, cash equivalents and marketable securities increased $24.8 million in the second quarter, to a record $148.7 million at quarter-end.

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.

“We are very pleased to report new quarterly records for both revenue and earnings per share in the second quarter,” commented Dr. Pierre-Yves Lesaicherre, president and chief executive officer of Nanometrics. “Our financial results reflect the first-half strength in memory capital spending, our gains in market share, and the demonstrable progress the company is making toward our financial model targets. Customer demand from both the NAND and DRAM market segments was very strong throughout the first half, and, as expected, will be lower in the second half. While we have seen some shifts in demand – both between NAND and DRAM, and among our key customers – our outlook for strong year-over-year growth in 2018 is consistent with our prior forecast.

“With Nanometrics’ revenue growth expected to outperform the overall increase in industry spending this year, our company has been scaling to support a much higher level of business. Our continued strong gross margin performance has enabled us to increase our investments in R&D and our global sales organization to support higher levels of revenue, while delivering strong profits and cash flows.” Dr. Lesaicherre concluded, “With our current visibility, we continue to forecast 2018 revenue growth of at least 20% year-over-year.  We remain confident that 2018 will be our fifth straight year of double-digit revenue growth, with expanding gross and operating margins, increased earnings per share, and significant free cash flow generation.”

Second Quarter 2018 Summary

Revenues for the second quarter of 2018 were $88.6 million, up 8% from $82.3 million in the first quarter of 2018, and up 38% from $64.4 million in the second quarter of 2017.  On a GAAP basis, gross margin was 57.4%, compared to 57.7% in the prior quarter and 52.2% in the year-ago period.  Total operating expenses were $30.1 million, compared to $27.0 million in the prior quarter and $23.0 million in the year-ago period. Operating income was $20.8 million, compared to $20.6 million in the prior quarter and $10.7 million in the year-ago period.  Net income was $17.7 million or $0.72 per diluted share, compared to $16.4 million or $0.67 per diluted share in the prior quarter and $8.3 million or $0.32 per diluted share in the second quarter of 2017.

On a non-GAAP basis, which excludes amortization of acquired intangible assets and severance included in cost of revenues, gross margin was 57.5%, compared to 57.8% in the prior quarter and 52.4% in the year-ago period.  Gross margin continued to benefit from a strong contribution of high-margin upgrades in both the first and second quarters, while the first quarter gross margin also benefited from a non-recurring favorable accrual adjustment. Non-GAAP operating expenses exclude severance and executive search and transition costs, and were $29.5 million, up from $26.5 million in the first quarter primarily due to higher R&D project spending, investments in the global sales organization, and increased accruals for variable compensation due to the increased level of profitability. Non-GAAP operating income was $21.4 million, compared to $21.0 million in the prior quarter and $11.1 million in the second quarter of 2017. Non-GAAP net income also adjusts for certain discrete tax items and the tax effect of non-GAAP adjustments and was $17.4 million or $0.71 per diluted share, reflecting a non-GAAP tax rate of 18%. This compares to non-GAAP net income of $16.5 million or $0.67 per diluted share in the prior quarter and $7.8 million or $0.30 per diluted share in the second quarter of 2017.

Business Outlook

Management expects third quarter 2018 revenues in the range of $70 to $78 million and gross margin is expected to be approximately 57%, plus or minus 1%, on both a GAAP and non-GAAP basis. Management expects third-quarter operating expenses of approximately $29 million, plus or minus $0.5 million, on both a GAAP and non-GAAP basis, and earnings in the range of $0.36 to $0.52 per diluted share on both a GAAP and non-GAAP basis. The earnings per share expectations reflect an improved tax rate of 19% to 20%, compared to the 22% to 23% rate provided previously.

Conference Call Details

A conference call to discuss second quarter 2018 results will be held today at 4:30 p.m. EDT (1:30 p.m. PDT). 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 3279607. 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, severance costs, executive transition and search costs, and certain discrete tax items, 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.
