Company Overview

What began in 1926 with two brothers logging the first electrical measurements in a well, SLB (NYSE: SLB) provides technology and services to help oil and gas companies locate reservoirs, drill wells, and produce hydrocarbons.

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. Luckily, SLB’s sales grew at a decent 10.9% compounded annual growth rate over the last five years. Its growth was slightly above the average energy upstream and integrated energy company and shows its offerings resonate with customers.

Energy cycles can be long enough that a single five-year period can still reflect one price environment, which is why an additional, decade-long view can help capture through-cycle performance. SLB’s annualized revenue growth of 1.2% over the last ten years is below its five-year trend, but we still think the results were respectable.

This quarter, SLB’s revenue fell by 4.5% year on year to $8.97 billion but beat Wall Street’s estimates by 3.4%.

Adjusted EBITDA Margin

Adjusted EBITDA margin captures the true operating profitability of an energy producer by removing accounting noise around depletion and capitalized drilling costs. It reveals how much cash the asset base generates before capital structure and reinvestment requirements shape reported earnings.

SLB was profitable over the last five years but held back by its large cost base. Its average EBITDA margin of 23.1% was weak for an upstream and integrated energy business.

Looking at the trend in its profitability, SLB’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.

In Q2, SLB generated an EBITDA margin profit margin of 24.5%, up 2.6 percentage points year on year. This increase was a welcome development, especially since its revenue fell, showing it was more efficient because it scaled down its expenses. This adjusted EBITDA beat Wall Street’s estimates by 22.9%.

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).

SLB has shown decent cash profitability, giving it some flexibility to reinvest or return capital to investors. The company’s free cash flow margin averaged 9.8% over the last five years, slightly better than the broader energy upstream and integrated energy sector.

The level of free cash flow is important, but its durability across cycles is just as critical. Consistent margins are far more valuable than volatile swings driven by commodity prices.

SLB’s ratio of quarterly free cash flow volatility to WTI crude price volatility over the past five years was 6.5 (lower is better), indicating great insulation from commodity swings. This indicates that its cash generation is relatively insulated from swings in commodity prices compared with most peers. This resilience supports access to capital in downturns and positions the company to act as a consolidator when distressed assets come to market at attractive prices.

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 SLB? 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.

SLB’s free cash flow clocked in at $900 million in Q2, equivalent to a 10% margin. This result was good as its margin was 3.4 percentage points higher than in the same quarter last year, building on its favorable historical trend.
