The nitrogen, ammonia and methanol producers that convert cheap North American natural gas into fertilizer and industrial chemicals have posted a real cross-stock rally — roughly 11% over the past month and 41% over the past year across CF Industries, Nutrien, Methanex and LSB Industries — but the trend data underneath that average is more fractured than the headline suggests.

CF Industries, North America's largest nitrogen fertilizer producer, is the only one of the four currently holding a confirmed uptrend. Nutrien, the world's largest potash producer and a major crop-nutrient retailer; Methanex, the world's largest methanol producer and distributor; and LSB Industries, a smaller US nitrogen producer pivoting toward clean ammonia, have all rolled into bear-classified trend readings even after the recent 30-day bounce. LSB's swing is the most extreme: its one-year gain has cooled from as much as 174% to roughly 44% as the stock unwound from a stretched valuation.

The rally's real driver looks less like a demand inflection than a supply shock. Commercial shipping through the Strait of Hormuz has been severely disrupted since late February 2026 amid the Iran-Israel-US conflict, stranding over a million metric tons of fertilizer cargo in the Gulf. That squeeze widened the feedstock-cost gap in North American producers' favor: European benchmark gas hit $16.3/MMBtu in mid-July while Henry Hub fell to $2.9/MMBtu over the same week, according to a weekly gas-price tracker — a cost advantage that does nothing on its own to fix the ag-demand picture.

CF's ammonia segment reported $627M of Q1 2026 net sales at a 36.2% gross margin, expansion the company attributed to a 25% jump in average selling prices rather than volume. Methanex posted a record $577M in Q2 Adjusted EBITDA as its realized methanol price more than doubled sequentially from $351/tonne in Q1 to $529/tonne, a windfall it ties to Middle East supply disruption that idled its own Trinidad Titan plant, even as its Geismar site produced over a million tonnes — some real volume growth alongside the price spike. But management is already signaling the reversal, having guided Q3 realized prices down to roughly $460-485/tonne with lower Adjusted EBITDA expected. Nutrien posted 19% revenue growth and record potash volumes in Q1 but missed on EPS and the stock slid 7%, then fell further in July on competition fears tied to a new $500M USDA FIELDS program meant to expand domestic fertilizer capacity.

Valuation reads name-by-name rather than as one category verdict. CF's trailing multiple compressed from roughly 13-14x in May to about 9.5x by late June even as the stock rose — earnings caught up faster than price, a supported advance. Nutrien looks closer to a possible dislocation: EBITDA grew and the multiple fell to about 12.4x from 15.6x, yet the stock dropped into bear territory on a policy scare rather than any business deterioration. LSB unwound from an extended near-44x multiple in May to about 17x by late June as its price decline caught up with reality — a justified de-rating. Methanex's picture is incomplete, with its trailing P/E not meaningful amid the cyclical trough and the Q3 guide-down still working through the numbers.

Underneath all of it, the agricultural demand base has not inflected. US farmers are expected to plant roughly 95 million acres of corn in 2026, down 3-5% from 2025 — corn absorbs roughly half of US synthetic nitrogen demand — while a broad urea benchmark, though up 16% on the month, still sits 8.7% below year-ago levels. China has meanwhile begun issuing fresh urea export quotas for June-August 2026, loosening a restriction that had helped keep global supply tight. Longer-dated capacity such as CF's Blue Point low-carbon ammonia project and LSB's El Dorado carbon-capture plan, both eligible for federal 45Q credits, remain years from contributing cash flow.

The setup

Where it stands — CF alone holds a confirmed uptrend among the four; Nutrien, Methanex and LSB Industries sit in bear-classified trend readings despite the recent bounce. Would confirm — Methanex's realized price holding near or above its $460-485/tonne Q3 guide, and the Henry Hub-TTF spread staying wide. Would invalidate — Resumed full Strait of Hormuz shipping or expanding Chinese urea export volumes that compress ammonia and urea benchmark prices further. Watch next — CF Industries reports Q2 2026 earnings on August 5, 2026, testing whether ammonia margin expansion persists or fades. Valuation — CF near 9.5x trailing earnings versus 13-14x in May; Nutrien near 12.4x versus 15.6x; LSB near 17x versus a stretched 44x; Methanex's multiple not meaningful mid-cycle.
