                                                                    Exhibit 99.1

McGrath RentCorp Announces Third Quarter Results; Q3 2005 EPS Increases 26% to
$0.48; Company Increases 2005 EPS Guidance Range to $1.57 to $1.62

    LIVERMORE, Calif.--(BUSINESS WIRE)--Nov. 3, 2005--McGrath RentCorp
(NASDAQ:MGRC) today announced revenues for the quarter ended September
30, 2005, of $77.8 million, compared to $72.5 million in third quarter
2004. The Company reported net income of $12.1 million, or $0.48 per
share, compared to $9.4 million, or $0.38 per share in the third
quarter 2004.
    For the third quarter of 2005, Mobile Modular's total revenues
increased 23% from $39.6 million to $48.7 million with both rental and
sales revenues improving on the continued strength in the educational
market. Sales revenues for the quarter included three large sale
projects totaling $11.7 million, of which $5.8 million were related to
damages caused by the recent hurricanes. The large sale projects
recognized in the quarter are of a similar nature as the single sale
project of $9.3 million recognized in third quarter 2004. The Company
views these types of large sale projects as unique opportunities and
generally would not expect sale projects of a similar size to occur on
a regular basis. Mobile Modular's significant increase in revenues led
to a 29% increase in its pre-tax income to $13.6 million. As of
September 30, 2005, Mobile Modular's backlog of sale projects related
to the recent hurricanes totaled $8.5 million and will be recognized
during the fourth quarter 2005. Looking forward, Mobile Modular
anticipates additional hurricane related rental and sale
opportunities, although the extent and duration remains uncertain. For
TRS-RenTelco, third quarter 2005 rental revenues decreased 2% to $18.4
million from $18.7 million, though, gross profit on rents increased to
$7.9 million from $7.2 million a year ago due to lower depreciation
expense, contributing to the quarter's pre-tax income increase to $5.1
million from $4.5 million.
    "Our third quarter 2005 earnings reflect our first full
quarter-over-quarter comparison of TRS-RenTelco's results since the
merger in June 2004," stated Dennis Kakures, President and CEO. "The
EPS increase of 26% for the quarter demonstrates the impact of new
classroom rental and sale activity in 2005 and greater profitability
in our test equipment business.
    "We continue to measure the strength of our modular business by
growth in both top-line rental revenues and gross profit on rents. We
believe these metrics provide the best gauge of the potential
horsepower of our modular economic engine going forward.
Quarter-over-quarter growth for rental revenues was 13% to $20.9
million and related gross profit grew 22% to $13.3 million, both of
which were records. We continue to benefit from the recurring rental
stream from educational facility rentals in the geographic markets we
serve. In California, we experienced higher than normal classroom
returns during the quarter as public school modernization projects
were completed and equipment was returned. We expect redeployment of
the great majority of these classrooms to occur over the next twelve
months. In Florida, business activity levels have continued very
favorably, as we support the needs of school districts in both
enrollment growth and the implementation of class size reduction.
Also, as a result of the recent hurricanes, we have and will continue
to respond to modular rental and sale opportunities in the Texas and
Southeastern markets.
    "For our test equipment business, pre-tax income and gross profit
on rents reached their highest levels to date for the combined
TRS-RenTelco business. Although top-line rental revenues were down
slightly from a year ago, we continue to more effectively manage our
rental inventory by selling underutilized equipment, ending the
quarter with utilization of 70.9%, which lowered depreciation as a
percentage of rents and improved rental margin to 42.9%. We also
continue to invest in the latest technology test equipment to support
new rental opportunities and believe we have put in place the cost
structure and operating disciplines that will support our future
earnings growth."

    THIRD QUARTER 2005 HIGHLIGHTS (AS COMPARED TO THIRD QUARTER 2004)

    --  Rental revenues increased 6% to $39.2 million. Within rental
        revenues, Mobile Modular increased 13% from $18.4 million to
        $20.9 million; TRS-RenTelco decreased 2% from $18.7 million to
        $18.4 million, yet improved sequentially from the second
        quarter 2005 level of $17.2 million.

    --  Sales revenues increased 10% to $31.0 million, resulting
        primarily from Mobile Modular's increased sales volume, which
        included $5.8 million of sales revenues related to
        requirements related to the recent hurricanes. Higher sales
        volume combined with a higher gross margin percentage, 26.5%
        in 2005 compared to 20.3% in 2004, resulted in a gross profit
        increase of $2.5 million. Sales revenues and related gross
        margins can fluctuate from quarter to quarter depending on
        customer requirements, equipment availability and funding.

    --  Depreciation of rental equipment decreased 7% to $10.8
        million, with Mobile Modular increasing 13% to $2.4 million
        and TRS-RenTelco decreasing 12% to $8.3 million from $9.4
        million in 2004. The TRS-RenTelco decrease was due to the
        determination in April 2005 to extend the useful lives on two
        models of test equipment (quarterly impact of $0.6 million)
        and the net impact of selling underutilized equipment and
        rental equipment becoming fully depreciated, offset by new
        equipment purchases.

    --  Debt decreased $11.4 million during the quarter to $154.6
        million, with the Company's total liabilities to equity ratio
        decreasing from 1.83 to 1 at June 30, 2005 to 1.80 to 1 as of
        September 30, 2005. On July 11, 2005, the Company amended its
        existing lines of credit to increase the borrowing capacity
        from $135.0 million to $195.0 million and extend the
        expiration dates to June 30, 2008. As of September 30, 2005,
        the Company, under its lines of credit, had capacity to borrow
        an additional $100.4 million.

    --  Dividend rate increased 27% to $0.14 per share for the third
        quarter 2005, as compared to $0.11 per share for the third
        quarter of 2004. On an annualized basis, this dividend
        represents a 2.0% yield on the November 2, 2005 close price of
        $28.18.

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

    excluding new equipment inventory and accessory equipment. The
    average utilization for the period is calculated using the average
    costs of rental equipment.
