The call in brief

Kirby delivered a solid second quarter of 2026, reporting EPS of $1.67 (up 11% sequentially and in line with the prior year) on revenue of $922.4 million, up roughly 8% year-over-year, and raised its outlook toward the upper end of full-year EPS growth guidance of 5%-15%. Marine transportation revenue grew 9% to $537 million (16.4% operating margin), though segment operating income fell 11% year-over-year on a temporary higher-fuel-cost headwind (to be recovered mostly in Q3) and elevated coastal shipyard activity; inland utilization held in the low 90% range with improving spot and term pricing amid tight capacity, while coastal utilization was strong in the high 90% range despite low-single-digit renewal softness in the smaller 80,000-100,000-barrel ATB segment. Distribution & Services revenue rose 6% to $385 million with operating income up 8% year-over-year and 63% sequentially, driven by power generation (+8%) and commercial & industrial (+12%) on strong marine repair activity; management raised the power generation backlog to $1-$1.5 billion, reaffirmed the installed base doubling in about 18 months, and announced Kirby Integrated Power Systems to capture a large behind-the-meter data-center service annuity in the coming years. Management framed the recovery in inland margins toward the prior ~28% peak as a slow, multi-year (potentially five-year) climb given that new-build economics remain ~40% away and only ~60 barges are being built industry-wide, and it reaffirmed full-year operating cash flow of $575-$675 million and $220-$260 million of capex while continuing aggressive buybacks ($59.7 million at an average of $142). The main pressures were the fuel-timing and coastal-shipyard drags on marine income, a working-capital-driven dip in second-quarter free cash flow, still-subdued (but sequentially improving) oil and gas, and persistent inflation in labor, steel, and electronics; on a consolidated basis operating income was $87.8 million (an operating margin of about 9.5%).

What went well
  • Kirby delivered second-quarter EPS of $1.67, up 11% sequentially and in line with the prior year, on revenue of $922.4 million (up ~8% year-over-year), and raised its outlook toward the upper end of full-year guidance.
  • Inland marine fundamentals strengthened, with barge utilization in the low 90% range, spot rates up low-to-mid single digits sequentially, and term renewals up year-over-year, supported by tight industry capacity.
  • Coastal marine utilization was strong in the high 90% range (above both Q1 and the prior year), reflecting robust refinery utilization and limited large-vessel availability.
  • Distribution & Services operating income jumped 63% sequentially (up 8% year-over-year) on favorable mix, with power generation revenue up 8% and commercial & industrial up 12% on strong marine repair activity.
  • Power generation demand remained exceptionally strong for behind-the-meter data center solutions, prompting management to raise the backlog outlook to $1-$1.5 billion (from $500 million-$1 billion) and reaffirm the installed base doubling in ~18 months.
  • The company returned $59.7 million to shareholders via buybacks at an average of $142, maintained a low 23.1% debt-to-capitalization ratio, and reaffirmed full-year operating cash flow of $575-$675 million.
What went wrong
  • Marine transportation operating income fell 11% year-over-year (to $88 million, 16.4% margin), hurt by a temporary higher-fuel-cost headwind (~5-10 cents, at the higher end) before contractual recovery and by elevated coastal shipyard activity.
  • Coastal term-contract renewals declined in the low single digits year-over-year due to market-specific softness in the smaller 80,000-100,000-barrel ATB segment (the most commodity-like part of the fleet).
  • Free cash flow was lower than expected in the quarter (operating cash flow $72.2 million versus $71.5 million of capex) on a working-capital build in receivables (PowerGen and fuel rebuilds).
  • Management framed the march back to peak inland margins (~28%) as a slow, multi-year (potentially five-year) climb rather than a rapid recovery, citing last year's surprise pricing dip.
  • Oil and gas within D&S remained below prior-year levels despite a 20% sequential revenue improvement, and persistent inflation in labor, steel, paint, and electronics continues to pressure the marine business.
