Company Overview

Named for the spiky wellhead equipment that reminded founders of desert cacti, Cactus (NYSE: WHD) manufactures wellheads, valves, and spoolable pipes used in drilling and producing oil and gas wells.

Revenue Growth

Cyclical sectors like Energy often flatter weaker operators during favorable price environments, but a longer-term lens separates those from businesses that can consistently perform across market cycles. Thankfully, Cactus’s 33.5% annualized revenue growth over the last five years was incredible. Its growth beat the average energy upstream and integrated energy company and shows its offerings resonate with customers, a helpful starting point for our analysis.

Even a long stretch in Energy can be shaped by a single commodity cycle, so extending the view to ten years adds another perspective and reveals which companies are built to grow regardless of the pricing regime. Cactus’s annualized revenue growth of 28.5% over the last ten years is below its five-year trend, but we still think the results suggest decent demand.

This quarter, Cactus reported magnificent year-on-year revenue growth of 64.3%, and its $449.5 million of revenue beat Wall Street’s estimates by 12.3%.

Adjusted EBITDA Margin

Cactus has done a decent job managing its cost base over the last five years. The company has produced an average EBITDA margin of 32.9%, higher than the broader energy upstream and integrated energy sector.

Looking at the trend in its profitability, Cactus’s EBITDA margin might have fluctuated slightly but has generally stayed the same over the last year. 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.

This quarter, Cactus generated an EBITDA margin profit margin of 29.5%, down 2.1 percentage points year on year. This contraction shows it was less efficient because its expenses grew faster than its revenue. This adjusted EBITDA beat Wall Street’s estimates by 29.2%.

Cash Is King

Adjusted EBITDA shows how profitable a company’s existing wells are before financing and reinvestment decisions, but free cash flow shows how much value remains after paying the cost of replacing those wells. In upstream energy, production naturally declines over time, so companies must continuously reinvest just to stand still. A producer can report strong EBITDA margins yet generate little or no free cash flow if its wells decline quickly or if new drilling is expensive. Free cash flow therefore captures not only how efficiently a company produces hydrocarbons today, but also how costly it is to sustain that production into the future.

Cactus has shown terrific cash profitability, enabling it to reinvest, return capital to investors, and stay ahead of the competition while maintaining an ample cushion. The company’s free cash flow margin was among the best in the energy upstream and integrated energy sector, averaging 22% over the last five years.

Absolute FCF margin levels matter but so does stability of free cash flow. All else equal, we’d prefer a 25.0% average free cash flow margin that is quite steady no matter how commodity prices behave rather than extremely high margins when times are good and negative ones when they’re tough.

Cactus’s ratio of quarterly free cash flow volatility to WTI crude price volatility over the past five years was 4 (lower is better), indicating excellent insulation from commodity swings. This stability supports superior capital access in downturns and positions Cactus to act as a consolidator when weaker peers are forced to retrench.

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 Crude prices in the case of Cactus? 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.

Cactus’s free cash flow clocked in at $104.6 million in Q2, equivalent to a 23.3% margin. The company’s cash profitability regressed as it was 2.6 percentage points lower than in the same quarter last year, but it’s still above its five-year average. We wouldn’t put too much weight on this quarter’s decline because investment needs can be seasonal, causing short-term swings. Long-term trends carry greater meaning.

Key Takeaways from Cactus’s Q2 Results

It was good to see Cactus beat analysts’ EPS expectations this quarter. We were also excited its EBITDA outperformed Wall Street’s estimates by a wide margin. Zooming out, we think this was a solid print. The stock remained flat at $52.33 immediately after reporting.
