Company Overview

With roots stretching back to 1862 when it began making equipment for early oil fields, NOV (NYSE: NOV) manufactures drilling rigs, drill bits, pumps, and other equipment used to drill 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. Unfortunately, NOV’s 9.9% annualized revenue growth over the last five years was mediocre. This fell short of our benchmark for the energy upstream and integrated energy sector and is a poor baseline for our analysis.

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. NOV’s performance shows it grew in the past five-year but relinquished its gains over the last ten years, as its revenue fell by 1.4% annually.

Revenue provides useful context, but it is heavily influenced by commodity prices and acquisitions. Production volumes, by contrast, reveal whether the underlying asset base is actually growing. Over the last two years, NOV’s other production averaged 1% year-on-year growth.

This quarter, NOV’s revenue fell by 2.5% year on year to $2.13 billion but beat Wall Street’s estimates by 2.4%. This quarter, NOV’s Other production fell by 14.9% year on year.

Adjusted EBITDA Margin

NOV was profitable over the last five years but held back by its large cost base. Its average EBITDA margin of 10.9% was among the worst in the energy upstream and integrated energy sector.

On the plus side, NOV’s EBITDA margin rose by 5.2 percentage points over the last year.

In Q2, NOV generated an EBITDA margin profit margin of 13.3%, up 1.7 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 40.8%.

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.

NOV has shown weak cash profitability relative to peers over the last five years, giving the company fewer opportunities to return capital to shareholders. Its free cash flow margin averaged 2.9%, below what we’d expect for an upstream and integrated energy business.

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

NOV’s ratio of quarterly free cash flow volatility to WTI crude price volatility over the past five years was 25.4 (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 NOV? 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.

NOV burned through $64 million of cash in Q2, equivalent to a negative 3% margin. The company’s cash flow turned negative after being positive in the same quarter last year, prompting us to pay closer attention. Short-term fluctuations typically aren’t a big deal because investment needs can be seasonal, but we’ll be watching to see if the trend extrapolates into future quarters.

Key Takeaways from NOV’s Q2 Results

It was good to see NOV 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 quarter featured some important positives. The stock traded up 4% to $20.63 immediately following the results.

NOV had an encouraging quarter, but one earnings result doesn’t necessarily make the stock a buy. Let’s see if this is a good investment. We think that the latest quarter is only one piece of the longer-term business quality puzzle. Quality, when combined with valuation, can help determine if the stock is a buy.
