Joseph B. Armes, CSW Industrials’ Chairman, President, and Chief Executive Officer, commented, "I am pleased to report all-time record revenue and adjusted EBITDA for the fiscal fourth quarter and full fiscal year 2026, while also delivering record adjusted EPS. Reaching one billion dollars in annual revenue in just ten years is a milestone worth celebrating. These record setting results are attributable to CSW's successful growth strategy, which was accelerated by the recent acquisition and integration of businesses in two of our three reporting segments. Our Contractor Solutions segment strengthened its HVAC/R and electrical product offerings while our SRS segment further diversified its end market exposures. In addition, during the fiscal fourth quarter, our Contractor Solutions segment completed the strategic acquisition of Duckt-Strip, creating an immediate opportunity to accelerate sales growth on a differentiated electrical cable in the fast-growing HVAC mini-split market."

Company Overview

With over two centuries of combined operations manufacturing and supplying, CSW (NYSE: CSW) offers special chemicals, coatings, sealants, and lubricants for various industries.

Revenue Growth

Reviewing a company’s long-term sales performance reveals insights into its quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Thankfully, CSW’s 20.9% annualized revenue growth over the last five years was incredible. Its growth surpassed the average industrials company and shows its offerings resonate with customers, a great starting point for our analysis.

Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. CSW’s annualized revenue growth of 16.9% over the last two years is below its five-year trend, but we still think the results suggest healthy demand.

This quarter, CSW reported wonderful year-on-year revenue growth of 34%, and its $309 million of revenue exceeded Wall Street’s estimates by 1.7%.

Looking ahead, sell-side analysts expect revenue to grow 19.9% over the next 12 months, an improvement versus the last two years. This projection is eye-popping and suggests its newer products and services will fuel better top-line performance.

Operating Margin

Operating margin is one of the best measures of profitability because it tells us how much money a company takes home after procuring and manufacturing its products, marketing and selling those products, and most importantly, keeping them relevant through research and development.

CSW’s operating margin has more or less stayed the same over the last 12 months , averaging 18% over the last five years. This profitability was elite for an industrials business thanks to its efficient cost structure and economies of scale. This is seen in its fast historical revenue growth and healthy gross margin, which is why we look at all three data points together.

Analyzing the trend in its profitability, CSW’s operating margin might fluctuated slightly but has generally stayed the same over the last five years. This raises questions about the company’s expense base because its revenue growth should have given it leverage on its fixed costs, resulting in better economies of scale and profitability.

In Q1, CSW generated an operating margin profit margin of 12.8%, down 6.7 percentage points year on year. Since CSW’s operating margin decreased more than its gross margin, we can assume it was less efficient because expenses such as marketing, R&D, and administrative overhead increased.

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.

CSW’s EPS grew at 30.1% compounded annual growth rate over the last five years, higher than its 20.9% annualized revenue growth. However, we take this with a grain of salt because its operating margin didn’t improve and it didn’t repurchase its shares, meaning the delta came from reduced interest expenses or taxes.

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 CSW, its two-year annual EPS growth of 23.4% was lower than its five-year trend. We still think its growth was good and hope it can accelerate in the future.

In Q1, CSW reported adjusted EPS of $3.14, up from $2.24 in the same quarter last year. This print easily cleared analysts’ estimates, and shareholders should be content with the results. Over the next 12 months, Wall Street expects CSW’s full-year EPS to grow 18.7% from $9.95 to $11.81.

Key Takeaways from CSW’s Q1 Results

It was good to see CSW beat analysts’ EPS expectations this quarter. We were also excited its EBITDA outperformed Wall Street’s estimates by a wide margin. On the other hand, its adjusted operating income missed. Overall, we think this was a decent quarter with some key metrics above expectations. The stock traded up 1.2% to $281.23 immediately after reporting.

CSW may have had a good quarter, but does that mean you should invest right now? When making that decision, it’s important to consider its valuation, business qualities, as well as what has happened in the latest quarter.
