What actually happened

Four companies that turn cheap natural gas into fertilizer and industrial chemicals — CF Industries, Nutrien, Methanex and LSB Industries — have posted a combined average stock gain of roughly 40% over the past year, and the pitch is simple: they buy the same gas that has crushed Appalachian and Haynesville drillers, so a weak Henry Hub price should widen their margins rather than shrink their revenue. But the underlying data show that story mostly describes one company. The rest of the group's gains trace to a geopolitical price spike in nitrogen fertilizer that has already reversed, and in one case has already shown up as a real earnings hit.

The spike is documented: urea prices jumped roughly 80%, from about $400 a ton to over $850, between February and April 2026 after the Strait of Hormuz conflict threatened Middle East supply routes. Prices then fell back to about $453 a ton by June as Iran resumed exports and a US-Iran deal eased the blockade. Ammonia and UAN, a liquid nitrogen fertilizer, followed the same pattern, falling further in July as the crisis premium unwound. That round trip lines up almost exactly with the stocks: three of the four names — Nutrien, Methanex and LSB — are down over the trailing 90 days (-8.2%, -13.5% and -26.3% respectively) even though a partial bounce leaves their 30-day returns positive. Trend-following price bands as of July 31 confirm the split: Nutrien, Methanex and LSB all carry bearish signals, the same label carried by every Appalachian and Haynesville gas driller sampled alongside them. Only CF Industries, which makes ammonia and urea at low-cost US gas-fed plants, holds a genuinely bullish signal, strengthening into a strong-uptrend reading in late July.

Company by company

CF Industries is the one name where the numbers agree with the price. Its enterprise value trades at 6.05 times EBITDA, 27% below its own 10-year median of 8.25 times, and its trailing price-to-earnings ratio has compressed to 9.5x from roughly 14x in May even as the stock held near highs — meaning earnings grew faster than the share price (EV/EBITDA data). The company reached a final investment decision on its roughly $4 billion Blue Point low-carbon ammonia project with partners JERA and Mitsui, underwriting most of the capex through offtake rather than the company's own balance sheet, and received a permitting boost from federal regulators. About $1.7 billion remains on its buyback authorization. Verdict: CONFIRMS.

Nutrien, the world's largest potash producer and a major crop-nutrient retailer whose 2,000-plus retail locations diversify it beyond pure nitrogen, actually improved its business in the first quarter — nitrogen segment earnings rose to $482 million and potash volumes set a record — even as its stock fell from about $75 to $63 in the same window and its trailing P/E compressed to 12.4x from 15.7x (Nutrien Q1 2026 results). That is a business improving while the tape got worse, a genuine dislocation, but only one quarter of confirming data exists so far. Verdict: INCONCLUSIVE.

Methanex, the world's largest methanol producer, closed a $2.05 billion acquisition of OCI Global's methanol business in mid-2025, adding Gulf Coast plants funded with cash, new shares and assumed debt (acquisition announcement). But methanol prices have stayed roughly flat through July, held down by ample Gulf Coast supply from Methanex's own restarted Geismar 3 plant and weak Chinese demand for methanol-to-olefins conversion (pricing data) — a supply glut, not the structurally short market the thesis assumes. Its trailing P/E is not meaningful near breakeven earnings. Verdict: CONTRADICTS.

LSB Industries, a smaller Oklahoma-based ammonia and nitrogen producer pivoting toward low-carbon products, is up 40.8% over the past year but its most recent quarter shows real damage: gross margin collapsed to 6.8% from 21.1% in the prior quarter, and net income swung to a $6.2 million loss from a $19.7 million profit, coincident with the nitrogen price crash. Verdict: CONTRADICTS.

The technical read

CF's bands strengthened to a strong uptrend on July 28, the only member of the group to genuinely diverge from the bearish signals carried by Nutrien, Methanex, LSB and every Appalachian/Haynesville driller sampled alongside them that same week — meaning three of the four "gas-buyer" chemical stocks currently carry the identical bearish label as the gas sellers they were supposed to be mirroring.

The setup

Where it stands — CF Industries alone shows fundamentals and valuation supporting its gains; Nutrien, Methanex and LSB do not currently confirm the cohort's feedstock-margin thesis. Would confirm — Nutrien's Q2 2026 nitrogen EBITDA holds near or above $482 million while its stock re-rates toward its improving fundamentals. Would invalidate — Urea or ammonia prices fail to stabilize above their June lows (~$453/t urea, ~$962/t ammonia) into the fourth quarter. Watch next — Nutrien's Q2 2026 earnings release and India's next urea tender award, both expected within weeks. Valuation — CF trades at 6.05x forward EV/EBITDA versus its own 8.25x 10-year median; Methanex's P/E is not meaningful near breakeven earnings.
