Nanometrics Reports First Quarter 2014 Financial Results

MILPITAS, Calif., April 29, 2014 — Nanometrics Incorporated (NASDAQ: NANO), a leading provider of advanced process control metrology and inspection systems, today announced financial results for its first quarter ended March 29, 2014.

First quarter Highlights

• Record IMPULSE^® Integrated Metrology revenues for Optical Critical Dimension (OCD) process control in high-volume foundry applications;

• Record UniFire^® revenues, with follow-on shipments for high-volume manufacturing in advanced 3D packaging and new customer acceptance for data storage;

• New qualifications of Atlas^® systems for OCD process control for advanced 14nm and early 10nm process development for FinFET logic devices; and

• Delivery of a SPARK™ advanced macro inspection system for rapid screening and characterization of defects for advanced litho cluster control.

GAAP Results
	Q1 2014	Q4 2013	Q1 2013
Revenues	$ 51,576	$ 46,159	$ 24,552

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 intangible assets.

Commenting on the company’s results, president and chief executive officer Dr. Timothy J. Stultz said, "First quarter revenues came in largely as expected, with earnings per share exceeding expectations at this revenue level. In the first quarter, our revenue growth primarily reflected significant OCD spending for 3D NAND and continued traction for our UniFire product line -- in both the advanced 3D packaging market as well as front-end adoption in the data storage market. As we look to the second quarter, we are seeing a considerable shift in the composition of our revenues, with NAND taking a pause, DRAM strengthening and logic revenues improving. Notably, in the second quarter we forecast a potential new record for our foundry business, and expect to achieve a more balanced mix of revenues among the top four semiconductor spenders than we have experienced at any time in our history. This outlook reflects the dynamic nature of industry spending patterns while also highlighting our market share gains and increasing penetration into pure-play foundries -- both of which are core strategic objectives for Nanometrics.

"As we look beyond the first half, recent reports by our customers and industry analysts suggest that the ramp in leading-edge 16nm FinFET foundry spending and additional deployments of 3D NAND capacity may be delayed into early 2015. While any such delays would impact a portion of our business pipeline for the second half, we continue to see a very strong growth year for Nanometrics in 2014, and are encouraged by continued technology investments by the world's leading semiconductor companies contributing to a positive outlook for 2015 as well."

First Quarter 2014 Summary

Revenues for the first quarter of 2014 were $51.6 million, up 12% from $46.2 million in the fourth quarter of 2013 and up 110% from $24.6 million in the first quarter of 2013. On a GAAP basis, gross margin was 46.8%, compared to 47.5% in the prior quarter and 42.7% in the year-ago period. Operating income was $2.0 million, compared to operating income of $1.3 million in the prior quarter and an operating loss of $9.6 million in the year-ago period. Net income was $1.6 million or $0.07 per diluted share, compared to net income of $0.6 million or $0.02 per diluted share in the prior quarter and a net loss of $5.6 million or $0.24 per share in the first quarter of 2013.

On a non-GAAP basis, which excludes amortization of acquired intangible assets, gross margin was 48.1% compared to 48.9% in the prior quarter and 45.4% in the year-ago period. Non-GAAP operating income for the first quarter was $2.8 million, compared to operating income of $2.1 million in the prior quarter and an operating loss of $8.7 million in the first quarter of 2013. Non-GAAP net income, which also adjusts for the income tax effect of non-GAAP adjustments, was $2.1 million or $0.09 per diluted share, compared to net income of $1.0 million or $0.04 per share in the prior quarter and a net loss of $5.0 million or $0.22 per share in the first quarter of 2013.

Balance Sheet Strength

At March 29, 2014, Nanometrics had $88.0 million in cash, cash equivalents and marketable securities and $147.6 million in working capital. Stockholders’ equity, excluding intangible assets, was $194.3 million, or $8.14 per share based on 23.9 million shares outstanding at quarter-end.

Business Outlook

Management expects second quarter operating expenses to increase between $0.1 and $0.9 million from the first quarter, with GAAP earnings to range from ($0.04) to $0.06 per share and non-GAAP earnings to range from ($0.03) to $0.08 per share.

Conference Call Details

A conference call to discuss first quarter 2014 results will be held today at 4:30 p.m. EDT (1:30 p.m. PDT).

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

Financial results such as non-GAAP gross profit, gross margin, operating income, net income, and net income per share, which exclude certain expenses, charges and special items, were not prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP). Management uses non-GAAP financial results, which exclude acquisition-related expenses such as amortization of acquired intangibles and transaction costs, asset impairments including certain excess and obsolete inventory charges related to a discontinued product line, restructuring charges, and other unusual and infrequent items to evaluate the company’s ongoing performance and to enable comparison to other periods that did not include these unusual and infrequent 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. 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.
