MONDOVI, Wis., Jan. 25 /PRNewswire-FirstCall/ -- Marten Transport, Ltd. (Nasdaq: MRTN) announced today its financial and operating results for the quarter and year ended Dec. 31, 2006 .

For the fourth quarter of 2006, operating revenue increased 5.0% to $131.7 million from $125.4 million for the same quarter of 2005. For 2006, operating revenue increased 12.8% to $518.9 million from $460.2 million for 2005. Operating revenue included fuel surcharges of $17.8 million and $77.3 million for the quarter and year ended Dec. 31, 2006 , compared with $19.1 million and $57.2 million for the quarter and year ended Dec. 31, 2005 . Operating revenue also included non-freight revenue principally from Marten's logistics and intermodal operations. Non-freight revenue increased 143.4% to $12.4 million for the quarter and 132.9% to $39.3 million for the year ended Dec. 31, 2006 , compared with $5.1 million and $16.9 million for the quarter and year ended Dec. 31, 2005 , respectively.

For the fourth quarter, net income decreased 27.0% to $5.2 million , or 24 cents per diluted share, from $7.1 million , or 32 cents per diluted share, for the same quarter of 2005. For the year ended Dec. 31, 2006 , net income decreased 2.2% to $24.5 million , or $1.12 per diluted share, from $25.1 million , or $1.14 per diluted share, for 2005.

Chairman, President and Chief Executive Officer Randolph L. Marten said, 'We continued to grow with our customers during the fourth quarter, though a more challenging freight environment and an increase in driver-related expenses impacted our profitability for the period. Operating revenue increased 5.0% in the last quarter of 2006, despite a 7.0% decrease in fuel surcharges. Non-freight revenue, consisting of our intermodal, brokerage, and MW Logistics operations, increased 143.4% to $12.4 million over the fourth quarter of 2005. Combining these business units with our trucking operations shows revenue growth, before fuel surcharges, of $7.6 million , or 7.1%, over the fourth quarter of 2005.

'We believe the freight market in the fourth quarter was characterized by less robust shipping demand and greater truck capacity than in the fourth quarter of 2005, with the amount of 'surge' freight significantly lower than in the last two years. This freight is highly profitable and the lack of it made a difference.

'Average freight revenue per tractor per week is one of our main measures of asset productivity. For the 2006 quarter, average freight revenue per tractor per week was $3,037 compared with $3,006 in the fourth quarter of 2005. This increase was due to slight improvements in both average freight revenue per total mile and in average miles per tractor from the fourth quarter of 2005.

'The primary changes in our expenses related to the increase in company- owned equipment and the corresponding decrease in independent contractor equipment. Salaries, wages and benefits increased 1.3% as a percentage of operating revenue, net of fuel surcharge, in the fourth quarter of 2006, partially due to the approximately 3.2 million mile increase in the number of miles driven by company drivers and partially due to increased health insurance expense. Higher self-insured medical claims increased our employees' health insurance expense by $1.5 million in the 2006 fourth quarter over the prior year period. These increases were partially offset by a decrease of $784,000 in compensation expensed for our non-driver employees under our incentive compensation program from the fourth quarter of 2005.

'Fuel expense, net of surcharge collection, increased 1.2% as a percentage of operating revenue, net of fuel surcharge, over the last quarter of 2005, due to an increase in company truck miles as a percentage of total miles and lower fuel economy. Our average cost of fuel in the fourth quarter was $2.45 per gallon compared with $2.58 per gallon in the same quarter of 2005.

'Our insurance and claims expense increased $974,000 , primarily attributable to increased claims experience. During the quarter, we experienced an uncharacteristic increase in accident severity. Our large self-insured retention resulted in an increase in claims expense, partially offset by a decrease in premium expense.

'Our operating ratio (operating expenses as a percentage of operating revenue) was 93.4% for the fourth quarter and 92.1% for the year of 2006 compared with 90.4% for the fourth quarter and 90.7% for the year of 2005. Netting fuel surcharges against fuel expense, as many of our peers do, would have produced an operating ratio of 92.4% for the fourth quarter of 2006 compared with 88.7% for the fourth quarter of 2005 and 90.7% for the year of 2006 compared with 89.4% for the year of 2005.

'Net income for the fourth quarter of 2006 included an income tax benefit of approximately $425,000 due to a decrease to our deferred income tax liability. The decrease was primarily due to a change in our income apportionment for several states. We expect our effective income tax rate to be in the range of 37% to 39% in 2007.

'We continue to experience below industry-average turnover with our drivers. In the fourth quarters of 2005 and 2006, our annualized driver turnover was less than 75%. This compares favorably with an annualized driver turnover rate estimated at approximately 120% by the American Trucking Associations.

'At Dec. 31 , our balance sheet reflected approximately $221.0 million in stockholders' equity and $58.7 million of borrowed debt, which results in a debt-to-total capitalization ratio of approximately 21.0%. Our net capital expenditures of $88.5 million in 2005 and $97.3 million in 2006 have represented a major investment to avoid the higher cost and less-efficient tractors that are mandated by federal emissions regulations beginning in 2007 and to build our trailer-to-tractor ratio for intermodal service. We expect capital expenditures in 2007 to decrease to approximately $45 million , net of proceeds of dispositions. Assuming net capital expenditures in that range and operating margins similar to the margins this year, we expect to generate cash flows to retire a substantial amount of our debt in 2007 or provide flexibility for other purposes.

'I'm also happy to announce that John Turner has returned to Marten as our Vice President of Sales. John will report to our Executive Vice President of Sales and Marketing, Tim Nash. John was previously Vice President of Sales for Marten, but left in early 2005 to pursue a career outside trucking. We're very pleased to have John back and know that he will be a strong addition to our sales team.'

Looking forward, Mr. Marten offered the following comments: 'Over the past four years, Marten's operating revenue, net of fuel surcharge, has grown 37.8%, and our earnings per diluted share have grown 64.7%. This represents compounded annual growth of 8.3% in operating revenue, before fuel surcharge, and 13.3% in earnings per share. For 2007, we expect to remain consistent with our long-term plan, which is for approximately 10% annual growth in operating revenue, before fuel surcharge, and earnings per share. However, if our expectation of an improving freight market during the second half of 2007 is realized, our goal would be to improve our operating ratio on a full-year basis. Based on tough comparisons from the first half of 2006, we would expect any improvement in operating ratio to come in the second half of the year.'
