The industry "is getting healthier and more vibrant by the month," David B. Henry, the company's chief executive said in an interview. Even so, he said, small, locally owned retailers and those serving the middle of the market "are still struggling," and the country's fiscal problems and political uncertainty also cast doubt on the future.

Veeco Instruments Inc.

1 Terminal Dr.

Plainview, 11803

Revenue: $979 million

Net Income: $128 million

Stock symbol: VECO (Nasdaq)

Employees: About 900, with 300 on Long Island

Industry: High-tech manufacturing

Chief executive: John Peeler

After two years of strong growth, Veeco's sales have slowed in 2012. The Plainview-based company sells machines that build light-emitting-diode, or LED, chips used in flat-panel televisions, cellphones, street lamps and a growing list of other products. Sales surged following the recession, and Veeco had hoped to top $1 billion in annual revenue for 2011. But revenue slumped during the last three months of the year, as Chinese government subsidies caused LED manufacturers to overbuild there, leading to a drop in demand for Veeco's equipment. For 2012, the company is forecasting that revenue will slip to between $520 million to $560 million. For its next growth spurt, Veeco hopes to capture a larger share of the market for machines that produce LED lights for use at airports, shopping centers and other large facilities.

Footnote: Financial reports are counted as 2011 results if more than half the fiscal year occurred in 2011; so, for instance, annual results reported in March 2012 are considered 2011 results. Several companies have disclosed 2012 compensation and financial results.
