                  MTI Technology Reports Fiscal 2006
First Quarter Financial Results; Revenue Increases 51% Year-Over-Year
                         and 10% Sequentially


    TUSTIN, Calif.--(BUSINESS WIRE)--Aug. 15, 2005--MTI Technology
Corporation (Nasdaq:MTIC), a leading multi-national storage solutions
and services company, today announced its financial results for the
fiscal year 2006 first quarter, ended July 2, 2005.
    Revenue for the quarter improved 51% year-over-year to $39.3
million compared to $26.0 million for the fiscal 2005 first quarter,
and increased 10% sequentially from $35.6 million in the fourth
quarter of fiscal 2005.
    Net loss applicable to common shareholders for the quarter was
$3.6 million or $.10 per share compared to a net loss of $9.5 million
or $0.27 per share for the preceding quarter and a net loss of $1.9
million or $.06 per share for the same quarter of the prior fiscal
year. Net loss applicable to common shareholders for the current
quarter includes a restructuring charge of $894,000, a foreign
currency loss of $840,000, and $620,000 of costs associated with the
amortization of a beneficial conversion feature and dividends payable
on Series A securities. Excluding these charges, operating loss for
the quarter was $1.2 million, our best performance in eight quarters.
    Product revenue for the first quarter increased 70% to $29.2
million from $17.2 million in the prior year period, and increased 17%
sequentially from $24.9 million in the fourth quarter of fiscal 2005.
Service revenue for the quarter was $10.1 million, a 15% improvement
year-over-year compared to $8.8 million in the comparable prior year
period, and a 5% decline sequentially.
    Gross margin for the first quarter was 20.5% compared to 23.2% in
the prior year period and 12.6% in the prior quarter. Service gross
margins improved significantly from the prior quarter, boosted by
better utilization, cost improvements, and reduced depreciation
charges, in line with the Company's previously announced plans.
    SG&A expenses of $9.3 million in the first quarter were up
year-over-year from $7.7 million and down sequentially from $10.7
million. The increase in expenses year-over-year is due primarily to
increased selling expense associated with the addition of new
salespeople and commissions on increased sales. Expenses were lower
than the prior quarter due to reduced administrative costs, including
the shutdown of our Irish facility.
    The Company recognized a restructuring charge of $894,000 in the
period associated primarily with remaining costs of the Irish facility
closure and a revaluation of a previously recorded facilities reserve.
    As of July 2, 2005, the Company had $7.8 million in cash and cash
equivalents. Uses of cash in the quarter primarily consisted of costs
associated with the Ireland facility closure and the operating loss.
    "We grew revenue nicely in the first quarter and made very good
progress toward achieving profitability," said Tom Raimondi, chairman,
president and CEO of MTI. "We experienced strong improvement in our
bottom-line results, which we expect to further improve upon
throughout the year."
    Raimondi added, "We are making very good progress and will
continue to drive aggressively towards profitability and increased
market share."
