AXT, Inc. Announces Profitability for the Fourth Quarter and Fiscal 2006
Gross Margin Improves to 38.2 Percent in Q4 2006

FREMONT, Calif., Feb. 28, 2007 — AXT, Inc. (NASDAQ: AXTI), a leading manufacturer of compound semiconductor substrates, today reported financial results for the fourth quarter and fiscal year ended December 31, 2006. The company’s financial statements have been presented to reflect the opto-electronics division as a discontinued operation for all periods presented.

Fourth Quarter 2006 Results
Revenue for the fourth quarter of 2006 was $13.1 million, up 4.2 percent from $12.5 million in the third quarter of 2006. Total GaAs substrate revenue was $11.1 million for the fourth quarter of 2006, up 4.7 percent from $10.6 million for the third quarter of 2006. Revenue in the fourth quarter from indium phosphide substrate sales was $456,000, compared with $340,000 in the third quarter; germanium substrate sales were $318,000, compared with $387,000 in the third quarter, and raw materials sales were $1.2 million, compared with $1.3 million in the third quarter.

Gross margin was 38.2 percent of revenue for the fourth quarter of 2006. This included a benefit from the sale of approximately $730,000 in fully reserved wafers, which positively affected the quarterly gross margin by 5.6 percentage points. AXT also benefited from overall yield improvements in the fourth quarter as a result of longer ingot growth, shorter cycle times, and more efficient slicing, which contributed to significant improvement in gross margins. By comparison, gross margin in the third quarter of 2006 was 27.7 percent. This included a benefit from the sales of approximately $802,000 in fully reserved wafers, which positively affected third quarter gross margin by 6.4 percentage points.

Operating expenses were $3.8 million in the fourth quarter of 2006 compared with $4.5 million in the third quarter of 2006. This decrease was primarily due to the absence of a $1.4 million impairment charge to write down the company’s U.S. property incurred in the prior quarter, partially offset by a $424,000 increase in the fourth quarter in accrued severance in research and development for the retirement of the company’s chief technology officer. Stock compensation expense for the fourth quarter of 2006 was $173,000, compared with $207,000 in the third quarter of 2006.

Income from operations for the fourth quarter of 2006 was $1.2 million compared with a loss from operations of $971,000 for the third quarter.

Net interest and other income for the fourth quarter of 2006 was $1.1 million compared with net interest and other income of $744,000 for the third quarter. Other income in the fourth quarter included a gain of $1.3 million on the sale of 474,000 shares of Finisar Corporation common stock, compared with a gain of $650,000 million on the sale of 300,000 shares of Finisar Corporation common stock in the third quarter. As of December 31, 2006 the company had disposed all of its Finisar shares.

The company recognized a net income tax benefit of $1.0 million for the fourth quarter of 2006, compared with a net income tax benefit of $862,000 in the third quarter.

Net income in the fourth quarter of 2006 was $3.4 million or $0.13 per diluted share, compared with a net income of $639,000 or $0.02 per diluted share in the third quarter. This $0.13 per diluted share includes approximately $0.05 from the sales of Finisar stock and $0.04 from our net income tax benefit, both of which are not expected to repeat in 2007.

Fiscal 2006 Results
Revenue for fiscal 2006 was $44.4 million, up 67.5 percent from $26.5 million in fiscal 2005. Gross margin was 28.7 percent for fiscal 2006 compared with 8.3 percent in the prior year. Net income for fiscal 2006 was $944,000 or $0.03 per diluted share, compared with a net loss of $12.2 million or $(0.54) per diluted share in the prior year.

Management Qualitative Comments
“2006 was a great year for AXT,” said Phil Yin, chief executive officer. “With strong market conditions, positive customer reception for our products and solid company-wide execution of our plans, revenues in 2006 increased by 67.5 percent and net income increased by 57 cents per diluted share over the prior year. During the fourth quarter, we were able to achieve tremendous yield improvements and cost reductions in nearly all areas of our manufacturing process, including longer ingot growth and shorter cycle times in crystal growing, and less material losses during slicing. These yield improvements and cost reduction programs helped to drive our gross margins to 38.2 percent in the fourth quarter and allowed us to achieve profitability sooner than we had expected. The last time the company achieved profitability was in the year 2000. As we enter 2007, we are energized by our achievements in product quality, yield improvements and sales penetration and we are optimistic about our prospects with increasing demand in the markets that we serve.”

Outlook for First Quarter, Ending March 31, 2007
AXT estimates that its revenue for the first quarter will increase to between $13.1 million and $13.6 million. Also, the company estimates that its net income per diluted share will be between $0.00 and $0.03 based on approximately 31.5 million weighted average diluted shares outstanding. This takes into account stock compensation expense of approximately $200,000.
