  McGrath RentCorp Announces Results for Second Quarter 2006; Q2 EPS of $0.34;
                          Rental Revenues Increase 12%

    LIVERMORE, Calif.--(BUSINESS WIRE)--Aug. 3, 2006--McGrath RentCorp
(NASDAQ:MGRC) today announced revenues for the quarter ended June 30,
2006, of $60.7 million, a decrease of 5%, compared to $63.9 million in
the second quarter 2005. The Company reported net income for the
second quarter 2006 of $8.7 million, or $0.34 per diluted share,
compared to $9.5 million, or $0.38 per diluted share, in the second
quarter 2005.
    During the second quarter 2006, the Company recorded a $0.9
million reduction to the provision for income taxes, or $0.03 per
diluted share, due to the reduction in the Company's deferred tax
liability as a result of a franchise tax law change enacted by the
state of Texas in May 2006. The reduction in taxes was partly offset
by $0.7 million of non-cash stock compensation expense included in the
second quarter 2006 results due to the adoption of Statement of
Financial Accounting Standards No. 123 (revised 2004), "Share-Based
Payment", ("SFAS No. 123R") effective January 1, 2006.
    For the Company's Mobile Modular division, pre-tax income
decreased 21% to $8.3 million from $10.5 million in the second quarter
2005. Rental revenues increased 10%, or $2.0 million to $21.6 million,
offset by lower rental margins resulting in gross profit on rents
decreasing 2% to $11.9 million from $12.2 million in second quarter
2005. Lower rental margins were the result of increased inventory
center labor and material costs to prepare a higher volume of
buildings to meet increased demand for commercial projects and
California classroom inventory for the upcoming school year, and
higher depreciation expense due to the 13% increase in average rental
equipment. Sales revenues decreased $3.9 million with gross profit
decreasing $0.6 million. Total gross profit decreased 3% from $16.6
million in second quarter 2005 to $16.2 million in second quarter
2006. Selling and administrative expenses increased $1.1 million to
$5.9 million in the second quarter 2006, primarily due to higher
personnel and benefit costs to support increased rental activity
levels and $0.4 million of non-cash stock compensation expense related
to the adoption of SFAS No. 123R. Allocated interest expense increased
$0.7 million due to higher average interest rates and average debt
levels to support higher rental equipment purchases.
    For the Company's TRS-RenTelco division, pre-tax income was $4.7
million for the second quarter 2006 and 2005. Rental revenues
increased 14% to $19.6 million compared to $17.2 million in the second
quarter of 2005 with gross profit on rents increasing 29% to $8.2
million from $6.4 million in the second quarter 2005. Sales revenues
decreased $3.9 million resulting in $1.1 million lower gross profit on
sales due to lower used equipment sales volume as a result of having
less underutilized rental equipment to sell. Selling and
administrative expenses increased $0.2 million due primarily to
non-cash stock compensation expense related to the adoption of SFAS
No. 123R. Allocated interest expense increased $0.3 million due to
higher average interest rates and average debt levels experienced by
the Company.
    "Second quarter results were below our expectations," stated
Dennis Kakures, President & CEO. "Our results reflected a reduction in
both modular and electronics equipment sales, the most difficult
element in our businesses to forecast, and a reduction in gross profit
on rents for modulars due to higher inventory center expenses. Based
on our results to date and our current forecast for the remainder of
the year, we are reducing our 2006 guidance range to $1.42 to $1.49
per diluted share.
    "While we are disappointed in our results for the quarter, we are
very pleased with the growth of rental revenues which is the key
metric of our business. Rental revenues for electronics grew quarter
over quarter at 14% and modulars at 10%. Strong growth in rental
assets typically speaks very favorably of our outlook for higher
rental revenue and profitability levels in the quarters ahead.
Accordingly, thus far in 2006 we increased the original cost of rental
assets by 14%, or $21 million for electronics and 8% or $31 million
for modulars.
    "TRS-RenTelco's second quarter rental revenue results are a
reflection of the continuing improved market conditions that we spoke
to during our first quarter conference call. We are continuing to see
favorable market conditions in the third quarter to date. It's
important to note that the increase in rental business activity levels
is across a broad range of product segments and markets that we
believe is reflective of an increasingly positive outlook for the
longer term health of our test equipment rental business. We are
proactively purchasing the latest technology test equipment to support
the increased demand we are seeing.
    "Pre-tax profit for TRS-RenTelco was flat compared to a year ago
mainly due to lower sales levels as a result of having less
underutilized equipment to sell. Sales levels can fluctuate quarter to
quarter based upon available equipment, customer demand and funding.
However, the success of our rental operations is what provides the
most significant and consistent earnings horsepower. With the gross
profit on rents increasing 29% to $8.2 million, our highest quarter
since the merger, our electronics rental business is beginning to find
its stride. As we have emphasized over the years, growth in rental
revenues, assets and gross profit on rents provide the most visibility
into the longer term earnings capability of our test equipment rental
business.
    "Mobile Modular's increase in rental revenues over the second
quarter of 2005 is primarily related to classroom shipments in the
third and fourth quarters of last year. We should experience a full 12
months of rental revenues in 2006 on the great majority of the
classroom orders shipped in the second half of 2005. We had another
strong first half of the year in classroom rentals and expanding our
school customer base in the Florida market. Florida continues to have
very favorable student population growth and will be active for many
years ahead in implementing class size reduction for all grade levels.
We are buying significant quantities of classrooms to support the
demand for additional educational space in Florida.
    "In California, we had satisfactory classroom rental booking
levels during the first half of the year. However, as expected, they
were not up to the level of the past few years due to the limited
availability of state bond monies for school modernization projects.
With the passage of a state-wide facilities bond measure in November
2006, we should see increased educational rental opportunities
beginning in early 2007. The need to modernize schools in California
continues to be high and we are positioning ourselves to take full
advantage of the anticipated increased opportunity levels in 2007.
Additionally, in the second quarter, we experienced a considerably
higher level of commercial rental opportunities, mainly driven by
increased business activity in residential and commercial
construction. Our broad inventory and ability to customize buildings
within our inventory centers enabled us to book a favorable level of
commercial opportunities during the second quarter. We should see
favorable rental revenue growth in the third quarter as a result of
classroom shipments and the increased level of commercial rental
activity.
    "The decline in modulars pre-tax profit of 21% from a year ago
stems chiefly from an increase in inventory center expenses and lower
sales revenue.
    "In the second quarter, we experienced approximately a $2 million
increase in inventory center expenses. This resulted from our
continued efforts in preparing off rent classroom inventory for future
rental, as well as the increase in commercial business activity levels
and the need to modify or convert equipment for specific applications.
Additionally, due to increased market demand for commercial buildings,
we employed a larger than normal number of subcontractors, at higher
labor rates compared to our in-house staff. It's important to note
that although the great majority of the expenses to prepare equipment
are fully absorbed in our second quarter results, the rental revenue
benefit will be recognized over the quarters ahead. We also
experienced higher than customary field service expenses during the
quarter. While field service issues occur from time to time, this was
a larger than normal effort with the majority of expenses incurred in
the second quarter. We should see marked improvement in our modular
operating profit levels beginning in the third quarter with gross
margin on rents expected to return to the 60% or higher range as
inventory center expenses decline and rental revenues increase.
    "Although modular sales revenues fell short of our expectations
for the quarter, we do not believe this presents any significant
concern for our modular business' longer-term earnings outlook. We
view sales as a byproduct of being in the rental business and although
we are actively engaged in selling both new and used equipment, we
focus our sales force on rentals which carry approximately twice the
margin as sales and provide a much more stable and enduring income
stream. Rental revenue growth is truly our economic engine.
    "The rental markets for both electronics and modulars continue to
be very favorable as reflected in double-digit rental revenue growth
for the quarter for each division and our level of investment in new
rental assets year to date. Our focus on creating sustainable earnings
growth over the long-term through an increasing base of rental
customers and higher rental revenues remains steadfast."

    SECOND QUARTER 2006 HIGHLIGHTS (AS COMPARED TO SECOND QUARTER
2005)

    --  Rental revenues increased 12% to $41.2 million. Within rental
        revenues, Mobile Modular increased 10% from $19.6 million to
        $21.6 million; TRS-RenTelco increased 14% from $17.2 million
        to $19.6 million.

    --  Sales revenues decreased 42% to $11.8 million, resulting from
        lower sales volume at Mobile Modular, TRS-RenTelco and
        Enviroplex. Lower sales volume was offset by a higher gross
        margin percentage of 27.3% in 2006 compared to 26.3% in 2005,
        resulting in a gross profit decrease of $2.1 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 increased 5% to $11.3
        million, with Mobile Modular increasing 18% to $2.6 million
        from $2.2 million in 2005, and TRS-RenTelco increasing 2% to
        $8.7 million from $8.5 million in 2005.

    --  Provision for income taxes was reduced $0.9 million during the
        second quarter 2006 to record the impact to the Company's
        deferred tax liability from a franchise tax law change enacted
        by the state of Texas in May 2006. As a result, the Company's
        effective tax rate was 32.1% for the second quarter 2006
        compared with 38.0% during the same period in 2005. Excluding
        the impact of the Texas law change, the provision for income
        taxes was based on an effective tax rate of 39.0%.

    --  Debt increased $13.0 million during the quarter to $189.5
        million, with the Company's total liabilities to equity ratio
        increasing from 1.68 to 1 at March 31, 2006 to 1.71 to 1 as of
        June 30, 2006. As of June 30, 2006, the Company, under its
        lines of credit, had capacity to borrow an additional $65.5
        million.

    --  Dividend rate increased 14% to $0.16 per share for the second
        quarter 2006, as compared to $0.14 per share for the second
        quarter of 2005. On an annualized basis, this dividend
        represents a 2.4% yield on the August 2, 2006 close price of
        $26.35.
