MARTEN TRANSPORT, LTD. ANNOUNCES
THIRD QUARTER FINANCIAL AND OPERATING RESULTS

MONDOVI, Wis., Oct. 22, 2007 – Marten Transport, Ltd. (Nasdaq/GS:MRTN) announced today its financial and operating results for the quarter ended Sept. 30, 2007.

Operating revenue, consisting of revenue from truckload and logistics operations, increased 6.7% to $145.0 million in the third quarter of 2007 from $135.8 million in the 2006 quarter. For the nine-month period of 2007, operating revenue increased 7.2% to $415.2 million from $387.2 million for the 2006 period. Truckload revenue increased 1.4% to $125.5 million from $123.8 million in the 2006 quarter. For the nine-month period of 2007, truckload revenue increased 2.4% to $367.4 million from $358.9 million for the 2006 period. Logistics revenue, which consists of revenue from brokerage and intermodal operations, increased 61.9% to $19.5 million from $12.0 million in the 2006 quarter. For the nine-month period of 2007, logistics revenue increased 68.9% to $47.9 million from $28.3 million for the 2006 period.

Operating revenue included fuel surcharges of $22.6 million and $61.1 million for the third quarter and nine-month period of 2007, compared with $22.5 million and $59.5 million for the third quarter and nine-month period of 2006. Operating revenue, net of fuel surcharges, increased 8.1% to $122.4 million in the 2007 quarter and 8.0% to $354.1 million in the 2007 nine-month period.

For the third quarter ended Sept. 30, 2007, net income decreased to $3.1 million, or 14 cents per diluted share, from $6.7 million, or 31 cents per diluted share, for the same quarter of 2006. For the nine-month period of 2007, net income decreased to $12.0 million, or 55 cents per diluted share, from $19.3 million, or 88 cents per diluted share, for the 2006 period.

Chairman, President and Chief Executive Officer Randolph L. Marten said, “Freight demand was less robust than usual during the third quarter, establishing a climate less conducive for volume growth or rate improvement with shippers. Our long-term customer relationships and diligent execution allowed us to overcome this to some extent, but below our expectations. As a result, average truckload revenue per tractor per week, net of fuel surcharges, increased slightly to $3,142 from $3,118 in the third quarter of 2006. Average truckload revenue, net of fuel surcharges, per total mile decreased to $1.482 from $1.492 in the third quarter of 2006 while average miles per tractor increased 1.5%.

“From a growth perspective, our average truckload tractor fleet increased slightly over the 2006 quarter. Logistics revenue increased $7.4 million, or 61.9%, 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.

“Given the tough rate environment we were not able to increase freight rates to cover higher costs. The main line items that affected our results compared with the third quarter of 2006 were fuel expense net of surcharge recovery, supplies and maintenance, insurance and claims, and gain on disposition of revenue equipment. All other material expenses were either controlled or varied with changes between compensation expense and purchased transportation.

“Our net fuel expense increased primarily due to an increase in the miles driven by company drivers as compared with independent contractors and an increase in the average cost of fuel during the third quarter to $2.83 per gallon from $2.79 per gallon in the 2006 quarter.

“The increase in supplies and maintenance was primarily due to a higher percentage of company-owned tractors in our fleet and an increase in the average age of our tractor and trailer fleets.

“An increase in physical damage claims with respect to our tractors and trailers primarily caused the increase in insurance and claims during the quarter.

“As expected, our gain on disposition of revenue equipment was lower in the third quarter of 2007 than in the third quarter of 2006 given our planned decrease in the number of revenue equipment dispositions. The decrease in gain affected operating income by approximately $1.5 million.

“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 3.3% increase in the number of miles driven by company drivers and an increase in health insurance costs of $510,000 versus the third quarter of 2006. Purchased transportation increased as the impact of fewer independent contractors was more than offset by increases in payments to third-party transportation providers associated with the growth in our logistics operations.

“Our operating ratio (operating expenses as a percentage of operating revenue) was 96.1% for the third quarter of 2007 compared with 91.4% for the third quarter of 2006.

“The third quarter and nine-month period of 2007 included a tax benefit of approximately $205,000, or 1 cent per diluted share, due to a decrease to our deferred income tax liability. The decrease in the income tax liability was primarily due to state income tax law changes and a change in income apportionment for several states. The effect on any future period is not expected to be material.

“For the quarter, we generated approximately $15 million in cash flow from operations and invested approximately $10 million in net capital expenditures. A portion of our capital expenditures included auxiliary power units for our tractors that will provide quiet heat, air conditioning, and electrical power for our drivers without idling the tractor engine. We expect these units to generate annual net savings of several thousand dollars per truck as they are deployed in our fleet. Auxiliary power units were installed in 742 of our tractors as of Sept. 30^th.

“At Sept. 30, 2007, our balance sheet reflected approximately $233.9 million in stockholders’ equity and $57.0 million in borrowed debt, for a debt-to-capitalization ratio of approximately 19.6%.”

Looking forward at the balance of 2007, Mr. Marten offered the following comments:  “We expect industry-wide capacity to exceed demand at least into the second quarter of 2008. Against the general background, as well as the normal seasonal slowness of the fourth and first quarters, we plan to decrease our tractor fleet by 100 to 200 units during the fourth quarter, depending upon market conditions. Our goal is to improve average miles per tractor and focus on the best available freight. Along with the tractor fleet reduction we expect to manage our non-driver staffing to remain above five tractors per non-driver, despite the growth of our logistics operations. Even with these profitability improvement measures and the addition of auxiliary power units, we do not expect our net income for the fourth quarter of 2007 to exceed last year’s level.”

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 the Company’s management and are inherently subject to significant 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 expectations concerning freight demand, cost savings of auxiliary power units, fleet reductions and personnel levels, and net income. 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 upgrading our 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; decreases in productivity that may offset or eliminate potential savings from the installation of auxiliary power units or unexpected maintenance or other costs associated with such units; 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. The Company does not assume, and specifically disclaims, any obligation to update forward-looking statements.
