KEX FY2026 market evaluation: at ~$95-130 share price + ~57-60M diluted shares = ~$5.5-7.5B market cap; ~$0 aggregate annual dividend (no dividend track; selected primary capital return via buybacks). Selected primary KEX peers: Genesis Energy (GEL, ~$1.5-2B Mcap; Marine Transportation MLP) + Crowley Maritime (private) + Ingram Marine + ACBL American Commercial Barge Lines + Marquette Transportation + Maersk (Danish; global Marine) + Caterpillar (CAT, ~$160-180B; Diesel Engine) + Cummins (CMI, ~$45-55B; Diesel Engine) + Wartsila (Finnish) + MTU Friedrichshafen + selected various aggregate global Inland + Coastal Marine Transportation + Distribution & Services + Diesel Engine Services companies. Selected KEX ~16-20x P/E + selected ~8-10x EV/EBITDA + selected ~$0 dividend yield + selected aggregate ~$3.65-3.85B aggregate FY2026 revenue + selected aggregate ~$6.85-7.45 aggregate FY2026 EPS + selected aggregate ~$200-350M aggregate FY2026 capital return + selected aggregate Inland Marine + Coastal Marine + Distribution & Services pipeline. FY2026 base case: ~$3.65-3.85B aggregate revenue + ~$6.85-7.45 adj. EPS + ~$200-350M aggregate capital return. Bull case: Inland Marine rate recovery to $0.05-0.07 per ton-mile + Distribution & Services Power Generation + Data Center Diesel Engine Services acceleration + Oil & Gas Pressure Pumping recovery + Federal Reserve interest rate cuts + post-2024 active buyback ratio (share count reduction) drives ~$3.75-3.95B aggregate revenue + ~$7.20-7.85 EPS. Bear case: Genesis Energy + Crowley Maritime + Ingram Marine + ACBL + Marquette Transportation + Caterpillar + Cummins + Wartsila + MTU Friedrichshafen competitive intensification + WTI Crude Oil + Petrochemical + Refined Petroleum cycle weakness + Mississippi River + Gulf Coast + Inland Waterways operational considerations + Federal Reserve interest rate cycle considerations + Power Generation + Data Center demand cycle considerations + post-2014 David Grzebinski CEO succession planning considerations drives ~$3.35-3.55B revenue + ~$5.50-5.95 EPS. The thesis depends on Inland Marine Transportation + Coastal Marine + Distribution & Services pipeline + aggressive share count reduction.
