MARTEN TRANSPORT ANNOUNCES FIRST QUARTER RESULTS

MONDOVI, Wis., April 18, 2024 (GLOBE NEWSWIRE) -- Marten Transport, Ltd. (Nasdaq/GS:MRTN) today reported net income of $9.6 million, or 12 cents per diluted share, for the first quarter ended March 31, 2024, compared with $22.5 million, or 28 cents per diluted share, for the first quarter of 2023.

Operating revenue was $249.7 million for the first quarter of 2024 compared with $298.0 million for the first quarter of 2023. Excluding fuel surcharges, operating revenue was $215.7 million for the 2024 quarter compared with $254.9 million for the 2023 quarter. Fuel surcharge revenue decreased to $33.9 million for the 2024 quarter from $43.1 million for the 2023 quarter.

Operating income was $12.3 million for the first quarter of 2024 compared with $29.0 million for the first quarter of 2023.

Operating expenses as a percentage of operating revenue were 95.1% for the 2024 quarter and 90.3% for the 2023 quarter. Operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharges, were 94.3% for the 2024 quarter and 88.6% for the 2023 quarter.

Executive Chairman Randolph L. Marten stated, “The freight market recession’s oversupply and weak demand, inflationary operating costs and cumulative impact of freight rate reductions and related freight network disruptions continue to significantly pressure our earnings. The value of our unique multifaceted business model is highlighted by the operating results for our dedicated and brokerage operations in the first quarter. Our operating results improved throughout the quarter after earning 2 cents per share in January, which was also impacted by widespread harsh winter weather.”

“We remain focused on minimizing the freight market’s impact on our operations while investing in and positioning our operations to capitalize on profitable organic growth opportunities, with fair compensation for our premium services, across each of our business operations for what comes next in the freight cycle as the market necessarily recovers from its current recessionary late stages. To that end, we have not agreed to rate reductions since last August.”
