Power Generation Surge and Marine Margins Drive Kirby to Record Full-Year Results
Earnings Hit Records on Strength in Power Generation and Marine Transportation
Kirby Corporation capped 2025 with record earnings, propelled by standout performance in power generation and marine transportation. Net earnings for the fourth quarter reached $91.81 million ($1.68 per share), and full-year earnings soared to $354.57 million ($6.33 per share)—well ahead of last year’s figures. Adjusted EBITDA in Q4 was $203.06 million, fueled by a year-over-year consolidated revenue gain of over $98 million despite mixed macro conditions and typical seasonal headwinds.
| Key Financial Highlights | Q4 2025 | Q4 2024 | FY 2025 | FY 2024 |
|---|---|---|---|---|
| Net Earnings ($M) | 91.81 | 42.82 | 354.57 | 286.71 |
| EPS (Diluted) | 1.68 | 0.74 | 6.33 | 4.91 |
| Total Revenues ($M) | 851.78 | 802.32 | 3,364.05 | 3,265.88 |
| Adjusted EBITDA ($M) | 203.06 | 172.33 | 781.02 | 708.33 |
Inland Marine and Coastal Margins Remain Robust
Kirby’s inland marine segment—responsible for 79% of marine revenues in Q4—benefited from improving barge utilization, which climbed from the mid-high 80% range to the low 90% range driving into 2026. Despite unfavorable weather and higher delay days (2,619, up 82% sequentially), inland operating margins were in the low 20% range, with operating income reaching $100.25 million and segment margins improving to 20.8% from 18.4% a year prior.
Coastal marine remained a pillar, achieving mid-high 90% utilization and an operating margin of approximately 20%. Revenues in this segment increased 22% year-over-year. Both inland and coastal marine benefited from limited new barge construction and steady customer demand, supporting positive pricing momentum as 2026 begins.
| Marine Transportation Metrics | Q4 2025 | Q4 2024 |
|---|---|---|
| Barge Utilization (Inland/Coastal) | Mid-High 80% / Mid-High 90% | Mid-High 80% / Mid-High 90% |
| Operating Margin | 20.8% | 18.4% |
| Delay Days | 2,619 | 2,681 |
| Ton Miles (in millions) | 3,492 | 3,220 |
| Revenue/Ton Mile (cents) | 10.9 | 11.9 |
Power Generation Growth Offsets Oil and Gas Weakness
The distribution and services division saw a 10% sequential and 47% year-over-year revenue leap in power generation, which now composes over half of segment revenues. Robust order activity and project wins drove this performance, reflected in a 20% increase in operating income for the year. This strength counterbalanced weaker results in oil and gas (down 45% year over year) and modest commercial/industrial softness. Segment operating margin for Q4 stood at 8.1%.
Prudent Capital Allocation: Debt Reduction and Share Repurchases
Kirby demonstrated disciplined capital management, repurchasing over one million shares ($101.6 million) at an average price of $98.53, and reducing debt by $130 million in Q4 alone. The quarter closed with $78.78 million in cash, $541.9 million in liquidity, and a manageable debt-to-capitalization ratio of 21.4%.
2026 Outlook: Inland and Power Generation Sectors to Lead the Way
Management expects 2026 earnings per share to be flat or up to 12% higher year-over-year, with steady operations and improving fundamentals across most segments. Inland barge utilization is projected to improve to the low 90% range for the full year, while coastal utilization is expected to remain at mid-90%. Seasonal weather will weigh on Q1 results, but operating margins are expected to firm as the year progresses.
Power generation is poised for continued growth, propelled by a robust backlog and rising demand for 24/7 backup power. Distribution and services revenue should remain flat to slightly higher year-over-year, with operating margins in the mid-to-high single digits on average.
| 2026 Outlook Highlights | Management’s Expectations |
|---|---|
| Barge Utilization (Inland/Coastal) | Low 90% / Mid 90% |
| Operating Margin (Inland/Coastal) | Low 20% / High teens |
| Distribution & Services Revs | Flat to slightly higher YoY |
| Cash from Ops (2026F) | $575M – $675M |
| Capex (2026F) | $220M – $260M |
Takeaway: Fundamentals Support Continued Growth
Kirby’s disciplined execution and exposure to high-performing sectors—especially power generation and marine transportation—have set the stage for more gains in 2026. Investors should keep an eye on utilization rates, power demand trends, and any macro catalysts (like tariffs or energy shocks) that could tip the balance further in Kirby’s favor. The next earnings release and management’s commentary will be key checkpoints for how these themes play out over the year.
