Cash provided by operating activities for the 2026 first quarter increased in comparison to the 2025 first quarter primarily due to increased net earnings and favorable working capital changes. The favorable working capital changes were driven by the timing of accounts payable and income tax payments, partially offset by the timing of accounts receivable collections. The 2025 first quarter included a $24.4 million estimated federal income tax payment as compared to none in the 2026 first quarter. For the 2026 first quarter, capital expenditures of $48.3 million included $34.6 million in KMT and $13.7 million in KDS and corporate, each more fully described under Cash Flow and Capital Expenditures below.

Previous wording

In 2026, the inland marine transportation market is expected to experience positive market dynamics due to limited new barge construction. The Company expects barge utilization rates to remain steady for the year with continued improvement in pricing as the year progresses. The Company also continues to see inflationary pressures and there remains an acute mariner shortage in the industry which continues to drive up labor costs. These pressures, along with the increasing cost of equipment, should continue to put upward pressure on spot and term contract prices. The coastal marine transportation market is also expected to see very favorable market conditions in 2026. The coastal marine transportation market should experience steady customer demand, keeping barge utilization at high levels with improving rates as the availability of equipment remains limited across the industry. There are no coastal barges currently under construction. The Company does expect more shipyard days in the coastal marine transportation market as compared to 2025.

Previous wording

The Company does expect some near-term cost headwinds in its inland marine transportation operations during the 2026 second quarter from rising fuel costs. Term and affreightment contracts contain fuel escalation clauses or provides for the customer to pay for fuel. Cost escalators and rate recovery mechanisms in the Company’s term contracts, while effective over time in allowing the Company to recover changes in fuel costs, create a delay that will lag near-term fuel cost increases. As a result, periods of rapidly rising fuel prices may temporarily compress margins and operating income until escalation adjustments are fully realized. The Company expects that lag to occur during the 2026 second quarter but should be ultimately realized in subsequent quarters as there is generally a 30 to 120 day delay before term contracts are adjusted for fuel costs. Fuel escalation clauses in term contracts and their effectiveness are discussed in more detail in Liquidity below and Item 1A – Risk Factors found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

Previous wording

The Company expects stable growth in KDS in 2026 as near-term volatility from supply issues, customers deferring maintenance, and lower overall levels of activity in the oil and gas market are offset by increased orders in the power generation market. In commercial and industrial, the demand outlook in marine repair remains steady while on-highway service and repair remains soft but has shown some recent modest improvement. In power generation, the Company anticipates continued strong growth in orders as data center demand and the need for behind the meter and backup power continues to be strong. In oil and gas, the Company expects revenues to be down as the transition from conventional diesel hydraulic fracturing to electric hydraulic fracturing continues to take place. The Company anticipates extended lead times and supply delays for certain original equipment manufacturer (“OEM”) products, especially in the power generation market, to continue throughout 2026. The Company does expect to be impacted in the 2026 second quarter by delayed OEM engine deliveries as certain impacted projects will shift from the 2026 second quarter into the 2026 second half.
