StockStory’s Take

Kirby’s second quarter was marked by a steep negative market reaction, with shares dropping sharply after results were announced. Management pointed to a combination of resilient demand in the marine transportation segments and strength in power generation as drivers of quarterly performance. However, CEO David Grzebinski acknowledged operational headwinds, citing “navigational and lock delays” in the Inland Marine business and ongoing supply chain constraints in the Distribution and Services division. The company also highlighted that chemical market softness and macroeconomic uncertainty have started to affect customer activity, particularly in July, with Grzebinski stating, “Our chemical customers have been fighting a negative tape for at least the last year or so, but their volumes have held up.”

Looking forward, management’s guidance is shaped by persistent supply-side constraints, inflationary pressures, and evolving trade policy risks that could dampen demand in select end markets. Grzebinski noted, “Recent shifts in trade policy have introduced additional uncertainty, influenced customer purchasing behavior and contributed to softness in select end markets.” While Kirby expects continued benefits from a backlog in power generation and limited barge supply, leadership cautioned that further deterioration in macro conditions could push full-year earnings toward the low end of expectations. The company is also focused on maintaining pricing discipline and operational efficiency in the face of labor shortages and cost pressures.

Key Insights from Management’s Remarks

Management attributed the quarter’s results to strong market fundamentals in both marine transportation and distribution, but flagged growing external macro pressures and supply chain challenges.

• Inland Marine resilience: Inland barge utilization remained high, with rates in the low to mid-90% range, despite navigational delays. Pricing gains in both spot and contract markets helped maintain operating margins, although management noted early signs of chemical market-related demand softness emerging in July.

• Coastal Marine tailwinds: The coastal segment benefited from tight industry capacity and steady customer demand, supporting high utilization and mid-20% year-over-year rate increases on term contracts. Reduced shipyard maintenance improved asset availability, raising operating margins into the high teens.

• Power Generation momentum: The Distribution and Services segment’s power generation business posted 31% revenue growth, driven by robust orders from data centers and industrial customers. Management highlighted a growing backlog and strong shipment activity, with Grzebinski emphasizing that “this power gen thing is real” as data center demand accelerates.

• Oil & Gas weakness offset by e-frac: Conventional oil and gas equipment demand remained soft, but profitability improved through disciplined cost management and growth in electric fracturing (e-frac) equipment deliveries, which offset lower conventional activity.

• Working capital and capital allocation: A significant working capital build to support power generation projects temporarily impacted cash flow, but management expects to unwind this as orders ship. The company signaled ongoing capital discipline, prioritizing share repurchases in the absence of large acquisitions.

Drivers of Future Performance

Kirby’s outlook for the remainder of the year centers on maintaining operational discipline as macroeconomic and trade-related headwinds introduce new risks to core markets.

• Marine supply-demand dynamics: Management expects constrained supply of both inland and coastal barges to support pricing and high utilization, but cautioned that spot market rates in inland marine could face pressure if chemical demand remains muted. Industry-wide labor shortages and inflation are expected to continue affecting costs.

• Power generation as growth driver: The Distribution and Services segment is banking on ongoing demand from data centers and industrial customers for backup and critical power, with a robust order backlog providing visibility into the second half. However, supply chain bottlenecks and customer sourcing challenges could limit near-term upside.

• Capital allocation and acquisition strategy: Kirby plans to use free cash flow for share repurchases unless attractive acquisition targets emerge, particularly in inland marine. Management noted that capital expenditures have been deferred to 2026 for select growth projects, boosting expected free cash flow this year, but warned that external shocks—such as further trade policy changes—could impact both investment timing and end-market demand.

Catalysts in Upcoming Quarters

Looking ahead, the StockStory team will be monitoring (1) whether inland marine spot pricing and barge utilization stabilize or deteriorate further in response to ongoing chemical market weakness, (2) the pace at which Kirby can convert its power generation backlog into revenue, especially as data center demand continues, and (3) the company’s ability to manage working capital and execute on capital allocation priorities, including share repurchases and potential acquisitions. Any significant changes in trade policy or supply chain conditions will also be key drivers of Kirby’s performance.

Kirby currently trades at $99.14, down from $120.08 just before the earnings. In the wake of this quarter, is it a buy or sell? The answer lies in our full research report (it’s free).
