Revenue Growth

Cyclical industries such as Energy can make mediocre companies look great for a time, but a long-term view reveals which businesses can actually withstand and adapt to changing conditions. Thankfully, Select Water Solutions’s 21.5% annualized revenue growth over the last five years was excellent. Its growth beat the average energy upstream and integrated energy company and shows its offerings resonate with customers.

Within Energy, a singular timeframe, even if it’s quite long-term, only sheds light on how well a company rode the last commodity cycle. To better assess whether a company compounds through cycles, we validate our view with an even longer, ten-year view. Select Water Solutions’s annualized revenue growth of 16.5% over the last ten years is below its five-year trend, but we still think the results suggest decent demand.

This quarter, Select Water Solutions reported year-on-year revenue growth of 8.7%, and its $395.8 million of revenue exceeded Wall Street’s estimates by 5.7%.

Adjusted EBITDA Margin

Adjusted EBITDA margin is an important measure of profitability for the sector and accounts for the gross margins and operating costs mentioned previously. Unlike operating margin, it is not distorted by accounting conventions around reserves, drilling costs, and assumptions on commodity consumption from the well or basin. Adjusted EBITDA highlights the economic reality of how much cash the rock produces before the capital structure (debt service) and the drilling budget (capex) are considered.

Select Water Solutions was profitable over the last five years but held back by its large cost base. Its average EBITDA margin of 16.8% was among the worst in the energy upstream and integrated energy sector.

On the plus side, Select Water Solutions’s EBITDA margin rose by 9.4 percentage points over the last year, as its sales growth gave it operating leverage.

In Q2, Select Water Solutions generated an EBITDA margin profit margin of 23.4%, up 3.5 percentage points year on year. This increase was a welcome development and shows it was more efficient. This adjusted EBITDA beat Wall Street’s estimates by 18.2%.

Cash Is King

As mentioned above, adjusted EBITDA ignores capital structure and drilling expenditure decisions. These are two huge aspects of an Energy producer, so in order to understand a comprehensive picture of business quality, an investor needs to account for these. Said differently, adjusted EBITDA margins could be solid but free cash flow is abysmal because decline rates of the asset are extreme and the drilling is expensive. Free cash flow tells you about not only the economics of the production that has happened but how much it costs to stay in business as well (further drilling or extraction).

Select Water Solutions broke even from a free cash flow perspective over the last five years, giving the company limited opportunities to return capital to shareholders.

While the level of free cash flow margins is important, their consistency matters just as much.

Select Water Solutions’s ratio of quarterly free cash flow volatility to WTI crude price volatility over the past five years was 124.2 (lower is better), indicating that its cash generation is far more sensitive to commodity-price swings than most peers. This elevated volatility limits its access to capital in downturns and makes it unlikely to act as a consolidator when weaker competitors come under pressure.

You may be asking why we wait until the free cash flow line to perform this stability analysis versus commodity prices. Why not compare revenue or EBITDA to WTI in the case of Select Water Solutions? Because what ultimately matters is not how much revenue or profit you earn when prices are high but how much cash you can generate when prices are low. Free cash flow is the superior metric because it includes everything from hedging prowess to growth and maintenance capex to management behavior during good times and bad.

Select Water Solutions’s free cash flow clocked in at $17.02 million in Q2, equivalent to a 4.3% margin. This result was good as its margin was 2.7 percentage points higher than in the same quarter last year, but we wouldn’t read too much into the short term because investment needs can be seasonal, leading to temporary swings. Long-term trends trump fluctuations.

Key Takeaways from Select Water Solutions’s Q2 Results

Sure, Select Water Solutions had a solid quarter, but if we look at the bigger picture, is this stock a buy?
