DYNAMEX ANNOUNCES THIRD QUARTER

FISCAL YEAR 2008 RESULTS

Third Quarter Highlights:

• Sales increase 9.1% to $113 million.

• Net income per fully diluted share increases 13.0% to $0.37.

• Three new franchise locations signed.

• Company expects FY 2008 earnings per share of $1.48 to $1.52.

June 4, 2008 — Dallas, Texas— Dynamex Inc. (NASDAQ: DDMX), the leading provider of same-day delivery and logistics services in the United States and Canada, today announced net income of $3.8 million or $0.37 fully diluted net income per share for the FY 2008 third quarter compared to $3.5 million or $0.32 per fully diluted share in the prior year.

Sales increased 9.1% to $113 million this quarter compared to the prior year. The exchange rate between the Canadian dollar and the U.S. dollar was approximately 15% higher this quarter than the same quarter last year. The Company estimates that higher fuel surcharges account for approximately 3.1% of the increase in sales. The core growth rate per day, the rate excluding changes in fuel surcharge revenues and foreign exchange, declined 0.6% this quarter. The prior year quarter includes approximately $5.1 million in sales for services provided on an interim basis to one customer in Canada. Excluding those one-time sales, the core growth rate per day would have been approximately 4.8%.

Selling, general and administrative (“SG&A”) expenses increased $1.5 million, or 7.1% compared to the same quarter last year. As a percentage of sales, SG & A expenses were 20.2% in the current year compared to 20.6% in the prior year quarter. Normal wage increases as well as additional personnel required to manage and operate new business started over the last year contributed to the dollar increase in SG&A expenses.

Operating income increased 11.1% compared to the prior year. Purchased transportation costs, the largest component of cost of sales represented 66.0% of sales in the current year quarter, compared to 65.2% in the prior year reflecting the impact of the increase in fuel surcharge

revenues. Other direct cost of sales declined from 8.4% last year to 7.8% in the current year quarter.

Income tax expense was $2.3 million, 38.1% of income before taxes in the current year quarter compared to $1.9 million, 35.8% of income before taxes in the prior year quarter. The higher income tax rate this quarter results from the higher proportion of pre-tax income generated in the U.S. than the previous year and an $80,000 positive tax adjustment in the prior year related to a reduction in the Canadian income tax rate. The Company’s effective income tax rate in the U.S. is approximately 41.6% and 34.1% in Canada.

Third Quarter Highlights
“Despite a challenging economy, high fuel costs and some of the worst winter conditions we have experienced in decades, our business delivered very solid financial results this quarter,” said Dynamex Chairman and CEO, Rick McClelland. “Sales increased 9.1% while our earnings per share increased 13.0% from a year ago.

“Our variable cost business model, industry leading technology and national presence puts us in a unique position to capitalize on the opportunities in a weak economy as more and more shippers consolidate vendors and outsource shipping needs in order to reduce costs,” added McClelland “If fuel costs remain high as forecasted, we expect to see some smaller competitors exit the business which could present additional opportunities for our business in terms of less competition in select markets and possible acquisition opportunities.

“Our sales pipeline continues to be strong from both our existing customer base and new customers and our affiliate model continues to progress,” continued McClelland. “We signed three new franchise locations during the quarter. We also terminated two startup franchise locations that did not become operational in accordance with expectations. At quarter end, we had 46 franchise locations.

“Our performance for the first nine months of this fiscal year has been solid in spite of serious economic challenges,” said McClelland. “I believe our performance demonstrates our ability to generate solid returns for our shareholders even in a tough economic environment. We are very excited about our position in the market, future growth opportunities and our ability to continue to profitably grow our business.

“Our outlook for the balance of our fiscal year remains strong as we expect year-over-year sales growth to be in the 10% to 11% range and fiscal year net income to range from $1.48 to $1.52 per fully diluted share,” concluded McClelland.

Long-Term Debt
Long-term debt was zero at April 30, 2008. Cash flow generated from operations was sufficient to fund operations and capital expenditures.

Margins
The gross margin this quarter was 26.2% of sales, below our stated target range of 26.5% to 27.0%, and below the 26.4% in the same quarter last year. The current year quarter includes a

bad debt provision of approximately $300,000 for one Canadian customer that filed for protection from its creditors and an additional accrual for prior years’ workers’ compensation

claims of $180,000. Absent those charges, our gross margin would have been 26.6%. Management expects the gross margin percentage to be in the Company’s target range in the fourth quarter of this fiscal year.

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) were $6.9 million, 6.1% of sales in the current quarter compared to $6.0 million or 5.8% of sales in the same quarter last year (see Reconciliation of Non-GAAP Financial Measures on page 7 of this release).

Cash Flow from Operations
Net cash provided by operating activities was $6.4 million this year compared to $7.6 million in the prior year. The principal factors that caused the reduction in net cash provided from operations are higher cash taxes in the current year, the payment for stock repurchase transactions consummated in FY 2007, the benefit last year from lessor financed leasehold improvements and higher rent abatements that were offset, in part, by a decrease in working capital in the current fiscal year required to finance accounts receivable. The Company’s cash position improved from $8.9 million at July 31, 2007 to $13.6 million currently.

Depreciation and Amortization
Depreciation and amortization (“D&A”) increased to $747,000 in this quarter from $554,000 in the third quarter last year due principally to the higher level of capital additions in FY 2007 and FY 2008 than in prior years. As a percent of sales, D&A was 0.7% in the current quarter compared to 0.5% in the prior year period.

Interest Expense
Interest expense for the three months ended April 30, 2008 was $48,000, $16,000 above the prior year period.

Stock Repurchase Plan
The Board of Directors has authorized management to repurchase a total of $58 million of Dynamex common stock. In May 2008, the Company repurchased 105,800 shares of Dynamex common stock at an average price of $24.06 per share, leaving a balance of $19.1 million in the current authorization. Management intends to continue to purchase shares from time to time using available cash or temporary borrowings from the bank facility.
