SECOND QUARTER FINANCIAL AND OPERATING RESULTS

MONDOVI, Wis., July 23, 2007 – Marten Transport, Ltd. (Nasdaq/GS:MRTN) announced today its financial and operating results for the quarter ended June 30, 2007.

Operating revenue, consisting of revenue from truckload and logistics operations, increased 5.3% to $138.8 million in the second quarter of 2007 from $131.9 million in the 2006 quarter. For the six-month period of 2007, operating revenue increased 7.5% to $270.2 million from $251.4 million for the 2006 period. Truckload revenue increased 1.2% to $123.7 million from $122.2 million in the 2006 quarter. For the six-month period of 2007, truckload revenue increased 2.9% to $241.9 million from $235.1 million for the 2006 period. Logistics revenue, which consists of revenue from brokerage and intermodal operations, increased 57% to $15.1 million from $9.6 million in the 2006 quarter. For the six-month period of 2007, logistics revenue increased 74% to $28.4 million from $16.3 million for the 2006 period.

Operating revenue included fuel surcharges of $21.1 million and $38.5 million for the second quarter and six-month period of 2007, compared with $20.9 million and $36.9 million for the second quarter and six-month period of 2006. Operating revenue, net of fuel surcharges, increased 6.1% to $117.7 million in the 2007 quarter and 8.0% to $231.7 million in the 2007 six-month period.

For the second quarter ended June 30, 2007, net income decreased to $4.3 million, or 20 cents per diluted share, from $7.5 million, or 34 cents per diluted share, for the same quarter of 2006. For the six-month period of 2007, net income decreased to $8.9 million, or 41 cents per diluted share, from $12.6 million, or 57 cents per diluted share, for the 2006 period. The second quarter and six-month period of 2006 included a one-time tax benefit of approximately $875,000, or 4 cents per diluted share.

Chairman, President and Chief Executive Officer Randolph L. Marten said, “During the quarter we continued to execute our program of providing excellent service to our customers with moderate fleet growth. The freight environment was challenging, however, which caused downward pressure on freight rates, fewer miles per tractor and increased non-revenue miles. As a result, average truckload revenue per tractor per week, net of fuel surcharges, decreased 3.4% to $3,108 from $3,216 in the second quarter of 2006. Average truckload revenue, net of fuel surcharges, per total mile decreased slightly to $1.470 from $1.472 in the second quarter of 2006 while average miles per tractor decreased 3.2%.

“From a growth perspective, our average truckload tractor fleet increased 5.1% over the 2006 quarter. Logistics revenue increased $5.5 million, or 57%, on a relatively small base. Logistics revenue consists of revenue from our internal brokerage and intermodal operations and from revenue associated with our 45% interest in MW Logistics, LLC, a third-party provider of logistics services.

“We continued to closely scrutinize our costs during the quarter. Even with an increase in revenue, we were able to improve our tractor to non-driver personnel ratio to 5.2 from 5.0 in the second quarter of 2006. Despite increased personnel efficiency, our overall cost structure increased. The two main items contributing to the increase were reduced tractor productivity, which less effectively covered fixed costs, and an increase in net fuel expense.

“Our average cost of fuel during the second quarter of 2007 was $2.73 compared with $2.75 in the second quarter of 2006. Our net fuel expense increased, however, primarily due to increased non-revenue miles, which we are accustomed to seeing in times of challenging freight demand.

“As in recent quarters, the percentage of independent contractors in our fleet declined and our truckload costs continued a shift toward wages, fuel, maintenance, and other expenses associated with company-owned equipment. The increase in salaries, wages and benefits was primarily due to a 4.2% increase in the number of miles driven by company drivers and an increase in health insurance costs of $517,000 versus the second quarter of 2006. Purchased transportation increased as the impact of fewer independent contractors was more than offset by increases associated with the growth in our logistics operations.

“As expected, our gain on sale of revenue equipment was lower in the second quarter of 2007 than in the second quarter of 2006 given our planned decrease in the number of revenue equipment dispositions. Increases in supplies and maintenance as well as insurance and claims also contributed to increased operating expenses in the second quarter.

“Our operating ratio (operating expenses as a percentage of operating revenue) was 94.2% for the second quarter of 2007 compared with 91.0% for the second quarter of 2006. Netting fuel surcharges against fuel expense, as many of our peers discuss, would have produced an operating ratio of 93.2% for the second quarter of 2007 compared with 89.4% for the second quarter of 2006.

“At June 30, 2007, our balance sheet reflected approximately $230.7 million in stockholders’ equity and $62.8 million in borrowed debt, for a debt-to-capitalization ratio of approximately 21.4%.”

Looking forward at the balance of 2007, Mr. Marten offered the following comments: “As

previously stated, it remains our long term goal to grow revenue and earnings at approximately a 10% compounded annual rate. Over the past several years, our revenue has grown somewhat less than 10% and our earnings per share have grown in excess of 13%. Under the current freight environment, we expect continued growth, yet difficulty for the remainder of 2007 in reaching double-digit revenue growth or improved earnings per share versus the second half of 2006.”

This press release contains certain statements that may be considered forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements may be identified by their use of terms or phrases such as “expects,” “estimates,” “projects,” “believes,” “anticipates,” “plans,” “intends,” and similar terms and phrases. Forward-looking statements are based upon the current beliefs and expectations of our management and are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, which could cause future events and actual results to differ materially from those set forth in, contemplated by, or underlying the forward-looking statements. In this release, forward-looking statements involve, among other things, our expected growth in revenue and earnings per share. The following factors, among others, could cause actual results to differ materially from those in forward-looking statements: the risk that our perception of the cyclicality of the markets we primarily serve is incorrect or there are recessionary economic cycles and downturns in customers' business cycles; increases in the prices paid for new revenue equipment and changes in the resale value of our used equipment causing our gain on disposition to fluctuate; excess tractor or trailer capacity in the trucking industry; decreased demand for our services or loss of one or more of our major customers; our ability to maintain profitability in or continue to grow our logistics business; surplus inventories; strikes, work slow downs, or work stoppages at the company, customers, ports, or other shipping related facilities; increases or rapid fluctuations in fuel prices as well as fluctuations in surcharge collection; the volume and terms of diesel purchase commitments; interest rates, fuel taxes, tolls, and license and registration fees; increased indebtedness, and associated interest expense, arising from maintaining a new fleet of equipment; shortages in supply of new equipment from manufacturers; increases in compensation for and difficulty in attracting and retaining qualified drivers and independent contractors; elevated experience in the frequency and severity of claims relating to accident, cargo, workers’ compensation, health, and other claims; changes in management’s estimates of liability based upon such experience and development factors; increases in insurance premiums and deductible amounts; seasonal factors such as harsh weather conditions that increase operating costs; competition from trucking, rail, and intermodal competitors; and regulatory requirements that increase costs or decrease efficiency, including new emissions standards for engines and the adoption of ultra-low sulfur diesel fuel. Readers should review and consider these factors along with the various disclosures by the company in its press releases, stockholder reports, and filings with the Securities and Exchange Commission.
