Marten Transport Results Presentation Deck

Improving Organic Operating Results MARTEN M+ TRANSPORT LTD. Nothing has changed since Chris Henry wrote this in Dec. 2018: "Quarter-over-quarter, year-over-year, Marten Transport (NASDAQ: MRTN) has delivered consistent, top quartile results. Key word is consistent. When compared to many of the others, you don't see very many blips in operating expenses or legal exposures that may cause multi-period hangovers for others. Everything I read about them through their earnings releases and SEC filings point to a very disciplined operating team... Marten has hung with and bettered the performance of many of the big dogs." Henry, Chris. Marten Transport Delivers the Goods. TCA Truckload Indexes, Dec. 2018 In each of the five years from 2018 through 2022, we set the then-current record for our highest annual operating revenue and operating income. We also achieved in each of 2020 through 2022 our then-best operating ratio, net of fuel s/c, for any year since we became a public company in 1986. Operating revenue increased 3.7% in Q1 '23 despite the softer freight market. "Energy and persistence conquer all things." - Benjamin Franklin The disciplined execution by our bright and talented people of a unique business model featuring our multifaceted business platform has driven and will continue to drive profitable growth.
