WHD's Earnings Multiple Isn't the Story — The Cash-Flow Engine Is

Cactus (WHD) trades at about 32 times forward earnings. That number alone tells you everything and nothing. It tells you the stock isn't cheap. It doesn't tell you the business has quietly transformed from a Permian-cycle wellhead maker into an expanding international equipment operator that turns most of its revenue into free cash flow while spending almost nothing on capital expenditures.

The market is still pricing the old story. The cash-flow numbers have already moved on.

The cash conversion that doesn't get attention

Look past the earnings multiple and the picture changes. Over the trailing twelve months, Cactus generated $324 million in free cash flow — cash remaining after all operating expenses and capital spending — on roughly $1.36 billion in revenue. That is a 23.8% free cash flow margin, up from the prior year on a 39.5% growth rate. Capital expenditures for the period were $43 million. Against $1.36 billion in sales, that's 3% of revenue.

The second quarter of 2026 sharpened the trend. Revenue hit $449.5 million — a 64% year-over-year jump, and a 12% beat against analyst estimates. The company generated $104.6 million in operating cash flow against $15.6 million in capex, leaving roughly $89 million in quarterly free cash flow. Adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization — a rough cash-earnings proxy) was $132.8 million at a 29.5% margin. Adjusted EPS of $0.93 beat the consensus estimate of $0.65 by 42%.

The headline that matters is the capital intensity. A company spending $43 million on factories and equipment while pulling in $1.36 billion in revenue is operating more like an industrial franchise than a typical oilfield services shop. Low capex means nearly all revenue growth flows directly into free cash flow rather than getting consumed by reinvestment. That is the mechanical advantage that makes the earnings multiple misleading — the GAAP numbers include acquisition-related amortization and purchase price adjustments that suppress reported earnings while the underlying cash engine runs at high margin.

What actually changed

The inflection wasn't incremental. In January 2026, Cactus closed its joint venture acquisition of Baker Hughes' surface pressure control business, becoming the majority owner and operator. The deal brought $344.5 million in cash proceeds before closing adjustments and restructured Cactus's geographic profile: 45% of the Pressure Control segment is now international.

That shift matters because it de-risks the single biggest vulnerability any Permian-adjacent business carries — the US drilling cycle. The Middle East, Latin America, and other international markets don't move in lockstep with US rig counts or WTI crude. Cactus's quarterly free cash flow volatility relative to WTI crude has run at a 4-to-1 ratio over the past five years, meaning the business absorbs commodity swings without the tape-level whiplash you'd expect from an oilfield name.

The backlog confirms the international shift is real, not aspirational. Remaining performance obligations — contracted revenue not yet delivered, a forward visibility metric — closed Q2 at $455.8 million, primarily driven by the Cactus International business. Post-quarter, management reported international purchase orders exceeding $130 million across both segments, with an additional $80 million plus in July alone.

Spoolable Technologies, Cactus's second segment, is the second growth vector. Q2 revenue hit $105.5 million and management expects another 15-20% sequential increase in Q3. A capacity expansion at the Baytown, Texas facility could add up to 20% more output. The company raised full-year capex guidance to $55-65 million to fund this build — a small number that keeps the capital-light profile intact.

Why the earnings multiple is the wrong lens

The 32x forward P/E catches the eye because it's high. But GAAP earnings for Cactus include significant non-cash charges from the Baker Hughes acquisition — inventory step-ups, intangible asset amortization, and other purchase price accounting adjustments that ran $20 million in Q2 alone. These are real expenses on the income statement but they don't consume cash. The free cash flow margin of 23.8% tells you the operating engine is generating cash at a rate the earnings number doesn't reflect.

Switch to the cash lens and the multiple compresses. At $324 million in trailing free cash flow and a $5.44 billion market cap, Cactus trades at roughly 16.8 times trailing FCF. With FCF growing 39.5% year-over-year, the forward multiple is materially lower.

The balance sheet backs the thesis. $366 million in cash, no bank debt, and $224 million of available revolver capacity. The company just raised its quarterly dividend for the sixth consecutive year, to $0.15 per share.

The setup and the risk

Here is the bridge. If 2026 revenue runs in the $1.6-1.7 billion range — consistent with the H1 run-rate of $838 million annualized, adjusted for the expected Q3 normalization in Pressure Control — and free cash flow margins hold at 22-24%, then 2026 FCF lands in the $350-410 million range. With 2027 continuing the international and Spoolable growth trajectory, a $400-450 million FCF run-rate is defensible. On roughly 80 million shares outstanding, that implies $5.00-5.60 per share in free cash flow.

A 16-17x multiple on that 2027 FCF estimate points to $80-95 per share. The stock sits at $67.90.

That math assumes the international momentum holds, the Baytown expansion delivers on schedule, and margins don't compress from tariff exposure or integration friction. The company is actively hedging tariff risk by shifting sourcing to Vietnam, but the global oil and gas backdrop remains uncertain — CEO Scott Bender acknowledged that directly on the Q2 call.

More immediate: Q3 will be lighter sequentially. Pressure Control revenue is expected to decline roughly 10% as the abnormally strong Middle East shipments from Q2 normalize. The stock could pull back if the sequential dip triggers commodity-cycle anxiety. That would be noise, not a thesis break — the backlog and post-Q2 order flow give visibility past the quarterly blip.

The tripwire

The thesis breaks if the free cash flow margin cracks below 18% for two consecutive quarters, signaling the capital-light model is degrading, or if the backlog falls below $300 million, suggesting the international pipeline is drying up faster than expected. Either would mean the cash engine is losing its edge and the rerating case collapses.

Until then, the earnings multiple is a distraction. The question isn't whether Cactus can justify 32 times GAAP earnings loaded with acquisition amortization. It's whether a business generating 24% free cash flow margins with minimal reinvestment needs and a $456 million backlog deserves a lower FCF multiple. The operating path suggests it does.

The setup is the cash conversion, the international de-risking, and the backlog visibility. The tripwire is a margin break or a backlog collapse. If neither happens, the FCF bridge does the talking.
