Future Outlook

For Q4 2025, inland marine market conditions are expected to remain stable with early signs of improvement, potentially leading to modest improvements in revenues and margins assuming tighter barge availability. Coastal marine market fundamentals are expected to remain very favorable, with steady customer demand and barge utilization holding in the mid to high-90% range, leading to comparable revenues and operating margins to Q3 2025. For the full year 2025, Distribution and Services revenues are expected to be up in the mid-single digits, with operating margins in the high-single digits, driven by strong power generation demand. Net cash provided from operating activities for 2025 is projected to be $620 million to $720 million. Capital spending for 2025 is expected to range between $260 million to $290 million, with $180 million to $210 million for marine maintenance and improvements, and up to $80 million for growth capital.

Management Comments

• Kirby's third quarter performance reflects our ability to adapt and deliver results, with continued strength in coastal marine and power generation, and focused execution in the face of softer inland market conditions.
• In inland marine, market conditions experienced near-term softness during the third quarter, primarily due to seasonally favorable weather, improved navigational conditions, a lighter feedstock mix for our refinery and chemical customers, and fewer barges undergoing maintenance across the industry.
• In the fourth quarter, we are already seeing market conditions improve and expect this trend to continue. We also continue to see constraints in long-term barge construction keeping new supply in check.
• In coastal marine, market fundamentals remained strong during the third quarter. Barge utilization levels were in the mid to high-90% range, supported by consistent customer demand and tight industry supply. Pricing continued to meaningfully improve, with term contract renewals up in the mid-teens range year-over-year.
• As we enter the fourth quarter, we remain focused on execution and disciplined capital allocation, while navigating evolving market conditions across our businesses. Despite near-term challenges in the inland market, we remain confident the inland barge cycle still has years to go given supply constraints.
• Our structural advantages in marine and growing backlog in power generation provide meaningful upside potential.
• With our strong balance sheet and robust free cash flow, we are well positioned to pursue strategic investments whether through targeted capital projects, selective acquisitions, or returning capital to shareholders.

Industry Context

The inland marine sector is experiencing near-term softness due to seasonal weather, improved navigational conditions, and a lighter feedstock mix for refinery and chemical customers, alongside muted petrochemical activity. However, long-term supply constraints in barge construction are expected to support future improvements. The coastal marine market remains strong, benefiting from consistent customer demand and tight industry supply, particularly for large capacity vessels, leading to significant pricing improvements. The power generation market is seeing robust demand from data centers and prime power customers, driving order growth and backlog, indicating a strong underlying trend for backup and behind-the-meter power applications. The oil and gas market continues to face challenges from lower conventional activity, but the company is adapting with strong performance in e-frac equipment and cost control.

Stakeholder Impact

• Shareholders benefit from increased earnings per share, strong free cash flow, and significant share repurchases, indicating a return of capital.
• Employees are impacted by the company's ability to adapt to market conditions and deliver results, particularly in growing segments like power generation.
• Customers in coastal marine and power generation are experiencing strong demand and tight supply, potentially affecting service availability and pricing.
• Customers in inland marine and conventional oil and gas may experience softer market conditions and reduced activity.

Next Steps

• A conference call is scheduled for 7:30 a.m. Central Daylight Time on October 29, 2025, to discuss the 2025 third quarter performance and the outlook for 2025.

Key Dates

Recommendation

Kirby Corporation demonstrates resilience with overall earnings and revenue growth, strong free cash flow, and active share repurchases. The coastal marine and power generation segments are performing exceptionally well, indicating strategic strengths. However, the near-term softness in the inland marine market and declining conventional oil and gas revenues present headwinds. While management is optimistic about long-term inland recovery, the mixed segment performance suggests a 'hold' position for investors to monitor the inland market's recovery and the sustained growth in power generation. The company's strong balance sheet and disciplined capital allocation are positive, but the current environment warrants a cautious approach rather than an aggressive buy.
