        AXT Announces Plan to Discontinue Opto-electronics Production

              SUBSTRATE PERFORMANCE ON TRACK FOR SECOND QUARTER

FREMONT, Calif. - June 24, 2003 - AXT, Inc. (Nasdaq: AXTI), a leading
manufacturer of compound semiconductor substrates, today announced that it will
discontinue the majority of its unprofitable opto-electronics production.
Approximately 165 employees at the California facilities of its opto-electronics
division will be given notice that they will be laid off in 60 days. In the near
future, the company will keep a minimum work force to produce and ship current
customer orders and to continue to sell products from its inventory.

AXT is reviewing its options for the discontinuation of the business, including
spin-off of the division which may involve a joint venture, sale of the division
or all or part of its assets, or liquidation. The gain or loss on disposal could
vary materially depending on how the disposal is effected. Therefore, no
estimates of the costs of discontinuation can be provided at this time.

"By taking this step, we will be able to focus our attention on growing our core
substrate business and bringing it to profitability, while conserving the
company's cash," said Morris Young, President and CEO of AXT.

Recently, AXT was sued by Cree Lighting for allegedly infringing a patent
regarding light emitting diodes that Cree licenses from Boston University. AXT
believes that the lawsuit is without merit and intends to defend itself
vigorously.

For the second quarter ending June 30, 2003, revenue from the continuing
substrate business is expected to be $8.2-$8.4 million and net loss from
continuing operations is expected to be $2.9-3.1 million or $0.13-$0.14 per
share. The company's net loss for the second quarter will also include charges
related to the discontinued opto-electronics business.

      The company will announce its second quarter results on July 23, 2003 and
will host a conference call with company management at 1:30 PM PST on July 23 to
announce its results. The call can be accessed at 785-832-2041; the passcode is

      SAFE HARBOR

This press release contains forward-looking statements regarding the company's
plan to discontinue its opto-electronics business, the outlook for its financial
performance for the second quarter of 2003, and its defense of a lawsuit
alleging patent infringement. Forward-looking statements address matters that
are subject to a number of risks and uncertainties that can cause actual results
to differ materially. Changes in the business might not match management's
forecasts. The company may not be able to discontinue the opto-electronics
business in an orderly manner and that may cause the costs of discontinuation to
increase. We may be found to have infringed patents held by others and we could
have to pay fines to the owners of these patents and our ability to continue to
ship products could be disrupted. Orders from our customers have been delayed
and reduced as a result of an imbalance or oversupply of products, and as
customers assess the impact that SARS might have on their business, and we
cannot predict how severe or prolonged these effects might be. Our business
operations remain potentially vulnerable to SARS and its aftereffects
influencing the volume and timing of customer orders, our ability to operate our
production facilities, acquire key supplies, and meet customer demand in other
parts of the world. For further discussion of the risks and uncertainties
regarding AXT's business, reference is made to AXT's filings with the Securities
and Exchange Commission, including the company's 10-K for the year ended
December 31, 2002, and 10-Q for the three months ended March 31, 2003 filed with
the Securities and Exchange Commission and available online by link from our
website at www.axt.com, or from the SEC's website at www.sec.gov. The Company
assumes no obligation to update the information in this press release.
