    McGrath RentCorp Announces Results for Fourth Quarter and Year-end; EPS
   Increases 31% for the Year; Company Announces 2-for-1 Stock Split and 27%
                               Dividend Increase

    LIVERMORE, Calif.--(BUSINESS WIRE)--Feb. 24, 2005--McGrath
RentCorp (NASDAQ:MGRC), a leading rental provider of modular buildings
for classroom and office space, and test equipment for general purpose
and communications needs, today announced revenues for the quarter
ended December 31, 2004, of $59.3 million, compared to $37.1 million
in the fourth quarter of 2003. The Company reported net income of $8.8
million, or $0.70 per diluted share, compared to $7.0 million, or
$0.57 per diluted share, in the fourth of quarter 2003. During the
quarter, rental revenues increased 84%, largely attributable to the
Company's TRS-RenTelco division. McGrath purchased substantially all
the general purpose and communications test equipment assets of
Dallas-based TRS, a division of CIT Group Inc. (NYSE:CIT) on June 2,
2004. Results for the fourth quarter and for the twelve months of 2004
include the results of TRS since that date.
    Total revenues for the twelve months ended December 31, 2004, were
$202.5 million, compared to $131.0 million in the same twelve-month
period in 2003. Net income for the twelve months ended December 31,
2004, increased to $30.0 million, or $2.42 per diluted share, a 31%
increase, compared to net income of $22.7 million, or $1.85 per
diluted share, in the prior year period.
    The Company also announced that the board of directors approved a
2-for-1 stock split and a proportional increase in the number of
common shares outstanding from 12,284,749 to 24,569,498. Each
shareholder of record as of March 11, 2005 will receive one additional
share for each outstanding share held on the record date. Trading will
begin on a split-adjusted basis on March 25, 2005. The board of
directors also declared a post-split cash dividend of $0.14 per common
share for the quarter ended March 31, 2005, an increase of 27%. On an
annualized basis, this dividend represents a 2.7% yield based on the
February 23, 2005, closing price. The cash dividend will be payable on
April 29, 2005, to all shareholders of record on April 15, 2005. The
2004 results disclosed in this release are not adjusted to reflect the
2-for-1 stock split unless described as such.
    In the fourth quarter of 2004, Mobile Modular had record rental
revenues of $19.1 million that contributed to an 11% increase in total
modular revenues to $30.7 million. Mobile Modular's fourth quarter
pre-tax income decreased 2% to $9.8 million from $10.0 million a year
earlier predominantly due to increases in maintenance expenses
associated with the preparation of unutilized equipment targeted for
potential rental opportunities in 2005, as well as higher allocated
overhead and interest expenses. Fourth quarter rental revenues at
TRS-RenTelco increased to $18.5 million from $3.6 million in the
fourth quarter of 2003, primarily from the TRS contribution, which
resulted in divisional pre-tax income of $3.9 million, compared to
pre-tax income of $1.1 million in the fourth quarter of 2003. Also, as
a result of the acquired TRS operations, the fourth quarter effective
tax rate was reduced from 39.9% to 35.0% due to recording a cumulative
true-up adjustment for the state income tax accrual rate, increasing
net income by $0.7 million or $0.05 per diluted share.
    "These results demonstrate the ongoing strength of Mobile
Modular's California classroom rental business, and in particular,
strong classroom booking levels experienced in early 2004 for
modernization and reconstruction projects," stated Dennis Kakures,
President & CEO. "The $19.1 million in rental revenues was our highest
quarter ever for our modular rental division. This growth reflects our
success as the leader in providing interim facilities to school
districts throughout California. In addition, we continue to be
pleased with the order activity we are generating in the Florida
market, which we entered less than a year ago. Based upon our results
to date, we are enthusiastic about the prospects for developing a
meaningful educational rental business in Florida.
    "Our test equipment rental business turned in a solid quarter as
we continued to work on key integration projects. With the initial
steps of integrating TRS-RenTelco in place, we are turning our full
attention to optimizing our day-to-day execution. We are excited about
the potential our industry leadership position, operating
efficiencies, and talented work force affords TRS-RenTelco in
positioning it for earnings growth in the years ahead.
    "The 27% increase in the first quarter 2005 dividend is a one-time
step up in the dividend pay out related to the TRS acquisition and
reflects the increased amount of free cash flow that TRS is providing.
Looking forward, we expect any future dividend increases beyond 2005
to generally reflect increases in our underlying growth rates. In our
view, we create value for shareholders employing free cash flow and
available debt capacity on strategic growth opportunities that we
believe may result in increased earnings, and distributing excess cash
flow in the form of dividends."

    Fourth Quarter 2004 Highlights as Compared to Fourth Quarter 2003

    --  Rental revenues increased 84% to $37.7 million. Within rental
        revenues, Mobile Modular increased 13% to $19.1 million,
        driven by California educational rentals; and RenTelco
        increased $15.0 million to $18.5 million, primarily due to
        TRS's contribution since June 2, 2004.

    --  Sales revenues increased 30% to $14.7 million, primarily due
        to increased sales volume of TRS-RenTelco, offset by lower
        sales volumes at Mobile Modular and Enviroplex, resulting in a
        gross profit increase of $1.1 million. Sales revenues and
        margins can fluctuate from quarter to quarter depending on
        customer requirements and funding.

    --  Depreciation of rental equipment increased 257% to $11.7
        million, primarily due to the purchase of TRS rental assets.

    --  Operating cash flow increased 67% to $31.0 million, primarily
        due to the revenue and net income contribution of the acquired
        TRS operations.

    --  Debt decreased $11.1 million during the quarter to $151.9
        million with the Company's total liabilities to equity ratio
        decreasing from 2.05 to 1 as of September 30, 2004, to 1.85 to
        1 as of December 31, 2004. At December 31, 2004, the Company,
        under existing bank lines of credit, had capacity to borrow up
        to an additional $43.1 million.

    --  Dividends increased to $0.22 per share for the fourth quarter
        2004 as compared to $0.20 per share for the fourth quarter
        2003.

    We suggest that this press release be read in conjunction with the
financial statements and notes thereto included in the Company's
latest Form 10-K and Forms 10-Q. You can visit the Company's web site
at www.mgrc.com to access information on McGrath RentCorp, including
the latest filings on Form 10-K and Form 10-Q.

    Financial Guidance

    Giving effect to the announced 2-for-1 stock split, the Company
expects its 2005 full-year earnings per share guidance to be in a
range of $1.45 to $1.55 per diluted share. This guidance range
excludes the impact of the third quarter of 2005 adoption of Statement
of Financial Standards No. 123R, "Share Based Payment", which requires
the expensing of stock options at fair value effective for quarters
beginning after June 15, 2005. Assuming the effective date for these
rules is not extended, the Company anticipates application on a
retrospective basis and expects the impact to reduce 2005 diluted
earnings per share by approximately $0.05 per share. Such a
forward-looking statement reflects McGrath RentCorp's expectations as
of February 24, 2005. Actual 2005 full-year earnings per share results
may be materially different and affected by many factors, including
those factors outlined in the "forward-looking statements" paragraph
at the end of this press release.
