David Grzebinski, Kirby’s Chief Executive Officer, commented, "Our second quarter results reflected strong execution across both businesses, driving an 11% sequential increase in earnings per share. In marine transportation, the inland market continued to strengthen, supported by steady customer demand, healthy barge utilization, and pricing improvements across both term contract renewals and spot market activity. While marine transportation margins were impacted by previously disclosed fuel cost headwinds in inland marine and elevated shipyard activity in coastal marine, customer demand remained healthy and overall marine transportation conditions were constructive during the quarter. In distribution and services, results benefited from continued demand growth in power generation and sustained growth in commercial and industrial markets. Overall, our businesses performed well during the quarter and delivered solid results, reflecting healthy end-market conditions and a continued focus on operational excellence.”

Company Overview

Transporting goods along all U.S. coasts, Kirby (NYSE: KEX) provides inland and coastal marine transportation services.

Revenue Growth

A company’s long-term sales performance is one signal of its overall quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Luckily, Kirby’s sales grew at an impressive 11.3% compounded annual growth rate over the last five years. Its growth beat the average industrials company and shows its offerings resonate with customers, a helpful starting point for our analysis.

We at StockStory place the most emphasis on long-term growth, but within industrials, a half-decade historical view may miss cycles, industry trends, or a company capitalizing on catalysts such as a new contract win or a successful product line. Kirby’s recent performance shows its demand has slowed significantly as its annualized revenue growth of 4.5% over the last two years was well below its five-year trend.

We can better understand the company’s revenue dynamics by analyzing its most important segments, Marine Transportation and Distribution and Services, which are 58.2% and 41.8% of revenue. Over the last two years, Kirby’s Marine Transportation revenue (petroleum products and chemicals) averaged 3% year-on-year growth while its Distribution and Services revenue (aftermarket parts and equipment) averaged 6.7% growth.

This quarter, Kirby reported year-on-year revenue growth of 7.8%, and its $922.4 million of revenue exceeded Wall Street’s estimates by 5.9%.

Looking ahead, sell-side analysts expect revenue to grow 6.1% over the next 12 months. Although this projection implies its newer products and services will fuel better top-line performance, it is still below average for the sector. At least the company is tracking well in other measures of financial health.

Operating Margin

Operating margin is an important measure of profitability as it shows the portion of revenue left after accounting for all core expenses — everything from the cost of goods sold to advertising and wages. It’s also useful for comparing profitability across companies with different levels of debt and tax rates because it excludes interest and taxes.

Kirby has done a decent job managing its cost base over the last five years. The company has produced an average operating margin of 8.8%, higher than the broader industrials sector.

Analyzing the trend in its profitability, Kirby’s operating margin rose by 22.4 percentage points over the last five years, as its sales growth gave it immense operating leverage. Its expansion shows it’s one of the better Marine Transportation companies as most peers saw their margins plummet.

In Q2, Kirby generated an operating margin profit margin of 13.3%, down 2.1 percentage points year on year. Since Kirby’s gross margin decreased more than its operating margin, we can assume its recent inefficiencies were driven more by weaker leverage on its cost of sales rather than increased marketing, R&D, and administrative overhead expenses.

Earnings Per Share

We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.

Kirby’s EPS grew at 47.2% compounded annual growth rate over the last five years, higher than its 11.3% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

We can take a deeper look into Kirby’s earnings to better understand the drivers of its performance. As we mentioned earlier, Kirby’s operating margin declined this quarter but expanded by 22.4 percentage points over the last five years. Its share count also shrank by 10.9%, and these factors together are positive signs for shareholders because improving profitability and share buybacks turbocharge EPS growth relative to revenue growth.

Like with revenue, we analyze EPS over a more recent period because it can provide insight into an emerging theme or development for the business.

For Kirby, its two-year annual EPS growth of 17.4% was lower than its five-year trend. We still think its growth was good and hope it can accelerate in the future.

In Q2, Kirby reported EPS of $1.67, in line with the same quarter last year. This print beat analysts’ estimates by 1.5%. Over the next 12 months, Wall Street expects Kirby’s full-year EPS to grow 18% from $6.51 to $7.68.
