Nutrien missed earnings badly in the third quarter. It reported $0.49 per share against a $0.66 consensus and a $0.63 Earnings Whisper number, a 22.2% shortfall. Earnings fell 47.3% year over year. Revenue told a different story: $6.064 billion beat the $5.86 billion consensus by 3.5% and grew 0.9%. The top line held up, but profitability below it eroded across several fronts at once. One measurement conflict matters. The company's own adjusted EPS was $0.61 and GAAP diluted EPS was $0.60, compared with $0.97 and $0.96 a year ago. The Earnings Whispers normalized figure is lower than either. On any basis, per-share earnings declined by more than a third.
The quality of the miss deserves scrutiny, because the damage was concentrated. Phosphate was the biggest swing. Segment adjusted EBITDA collapsed to $8 million from $122 million, and gross margin turned negative at -$50 million. Higher sulfur costs pushed cost of goods sold to $939 per tonne from $643, overwhelming a 17% jump in realized price. Retail adjusted EBITDA slipped to $203 million from $230 million. Crop nutrient margins fell to $105 per tonne from $119 as higher-cost nitrogen inventory sold through, and proprietary product gross margin dropped to $231 million from $268 million. Below the operating line, the effective tax rate jumped to 40% from 26% on geographic mix. Share-based compensation also rose to $75 million from $28 million as the stock climbed. Consolidated adjusted EBITDA fell 8% to $1.31 billion.
The core upstream franchise looks considerably healthier than the headline. Potash adjusted EBITDA was essentially flat at $730 million, up from $658 million in the second quarter and $578 million in the first. Volume guidance was raised again, to 14.3-14.8 million tonnes. One soft spot was the quarter's controllable cash cost, which rose to $67 per tonne from $56 as turnaround activity cut production. Nitrogen volumes fell to 2.35 million tonnes from 2.83 million with Trinidad and New Madrid offline. Even so, gross margin per tonne improved to $156 from $139, helped by natural gas at $2.18 per MMBtu versus $3.54. Nitrogen volume guidance also moved up. Management's tone on the call was more forward-looking. It introduced a 2027 global potash shipment forecast of 75-79 million tonnes, citing limited new supply, and framed nitrogen markets as tight into 2027.
The guidance picture is the central tension. Retail adjusted EBITDA guidance was cut to $1.72-1.85 billion from $1.75-1.95 billion, the first reduction after the range had been held for three straight quarters. Proprietary margin growth slowed to 9% year to date from a 10%-plus pace at mid-year, and fourth-quarter proprietary gross margin was guided roughly flat. Retail was supposed to be the stable, structural growth engine, so bears have legitimate ammunition here. Additional pressures include higher Chinese urea exports of 8-9 million tonnes, elevated Chinese potash port inventories and tight Brazilian credit.
The portfolio actions are meaningful but cut both ways. The phosphate review ended without a sale, because management judged the bids inadequate. Instead, Nutrien will keep Aurora and close White Springs in the second quarter of 2027. Management expects the closure to lift adjusted EBITDA and free cash flow and to trim roughly $50 million of annual sustaining capital and lease payments. Paired with the indefinite Trinidad shutdown, the move also brings fourth-quarter impairment charges. Those charges will be assessed against roughly $430 million and $760 million of carrying value, respectively, so GAAP results will be noisy. Cash returns are the steadier positive. Operating cash flow is up 17% year to date, buybacks are up 36%, and repurchases are running near $75 million a month into the fourth quarter. An Investor Day later in November is the next catalyst.
Investors entered the report in a far more optimistic mood than they leave it. Earnings Whispers sentiment fell from 0.23 to roughly -0.02, a substantial swing from modestly positive to neutral-to-slightly negative. Shares are still up 11.0% since the open after the August report, at $72.07. However, they sit only 1.3% above the 200-day moving average of $71.13, leaving little technical cushion. Price trend readings are neutral while the AVWAP trend is negative.
The bottom line is that Nutrien delivered a genuine miss driven by phosphate cost inflation, retail margin slippage and a punitive tax rate. Meanwhile, potash, nitrogen unit economics and capital returns continued to improve. The retail guidance cut erodes the downstream stability thesis just as the company asks investors to look toward 2027. That leaves the Investor Day carrying more weight than usual.
