        Ibis Technology Announces Second Quarter 2004 Results

    DANVERS, Mass.--(BUSINESS WIRE)--July 21, 2004--

    Company announces continued focus on implanter equipment business;
discontinuance of the wafer-manufacturing and sales business

    Ibis Technology Corporation (Nasdaq NM: IBIS), a leading provider
of SIMOX-SOI implantation equipment to the worldwide semiconductor
industry, today announced its financial results for the second quarter
ended June 30, 2004.
    Total revenues for the quarter were $2.1 million, compared to $2.1
million in the preceding quarter, and compared to $11.7 million in the
second quarter of 2003, which included revenue of approximately $8
million related to the sale of an i2000 implanter that was accepted by
the customer in the second quarter of 2003.
    Net loss for the 2004 second quarter was $3.4 million, or $0.32
per share, compared to a net loss of $3.5 million, or $0.33 per share,
in the preceding quarter. Net income in the second quarter of 2003 was
$1.2 million, or $0.13 per share.
    For the first half of 2004, total revenues were $4.1 million
compared to $13.1 million for the first half of last year, which
included approximately $8 million in equipment revenue as mentioned
above. Net loss for the first six months of 2004 was $6.8 million, or
$0.64 per share, compared to a net loss of $3.1 million, or $0.32 per
share, for the same period last year.
    "We are very pleased that during the second quarter we shipped the
i2000 implanter that had been ordered earlier in the year by a leading
wafer manufacturer. The system is now being installed at the
customer's plant," said Martin J. Reid, president and chief executive
officer of Ibis Technology Corporation. Revenue recognition for this
implanter, which is expected to amount to approximately $7 million,
will be based on final customer acceptance, the timing of which may
vary depending on a number of factors. As a result Ibis cannot provide
any guarantees with respect to when or whether it will recognize
revenue on this transaction.
    The company received a second payment from a customer upon
shipment of the i2000 implanter mentioned above during the second
quarter. This amount has been recorded as deferred revenue. The
company has also started procuring selected parts for two additional
machines with the intention of manufacturing one tool in anticipation
of an order during the second half of 2004. The company has
approximately $14 million of cash on hand. With just one additional
order and the operational changes the company expects to put into
place during the third quarter, the company anticipates that based on
its most recent forecast it could sustain operations for the
foreseeable future or for about 18 months.
    In a separate press release issued by Ibis today, the company
announced that, consistent with its focus on its equipment business,
it has decided to discontinue the wafer-manufacturing portion of its
business. "From our perspective, the increased interest in our SIMOX
implanters that we are seeing from leading wafer manufacturers is a
signal that it's time for us to concentrate our total efforts on our
equipment business," said Reid.

    Corporate Outlook

    Commenting on the company's future outlook, Reid said, "We are now
focused exclusively on our equipment business. We anticipate that we
will be phasing out production volume wafer manufacturing early in the
third quarter; as a result, we expect that future wafer revenues will
be small. Equipment revenues will depend primarily on whether and when
our customer accepts the machine that we shipped in the second
quarter."
    "Although the decision to increase our focus on our equipment
business is consistent with our long-term strategy, we believe that it
will cause 'lumpy' revenues when viewed on a quarter-to-quarter
basis," said Reid. "This is likely to remain the case until implanter
sales increase substantially."

    Ibis will host a teleconference to discuss its second quarter
results and outlook for the future on July 21, 2004 at 5:00 p.m. ET.
