Neste Swings Back to Strong Renewable-Fuel Margins in Third-Quarter Results

Neste's renewable-fuels business, the barometer everyone in the biodiesel trade watches, snapped back hard in the third quarter. On October 29 the Finnish company reported that its Renewable Products division earned 266 million euros in comparable EBITDA for the July-to-September period, up from just 106 million euros a year earlier. The comparable sales margin rose to 480 dollars per ton from 341 dollars, and sales volume climbed to 1,046 thousand tons. After a first half that gutted margins across the sector, that is the recovery producers had been waiting for.

The group numbers tell the same story. Neste posted a comparable operating profit of 435 million euros for the quarter, which it called its highest quarterly result ever. Comparable EBITDA reached 531 million euros, nearly double the 293 million euros of a year ago. Revenue fell to 4,534 million euros from 5,624 million, but that drop reflects lower market prices and currency swings, not weaker demand. The profit line is what matters here, and it moved the right way.

What drove the rebound

Two things turned. Margins widened, and record aviation-fuel sales fattened the mix. Renewable diesel priced better in the quarter as European demand firmed, and Neste sold a record 251 thousand tons of sustainable aviation fuel, more than double the 112 thousand tons booked in the third quarter of 2024. SAF carries a premium over ordinary renewable diesel, so shifting more barrels into jet fuel lifts the blended margin without any extra volume.

CEO Heikki Malinen tied the result to the company's cost work rather than to luck in the market. "We delivered improved results in the third quarter, underpinned by successful continuation of our performance improvement program and reliable, safe operations," he said. Reliable operations are not a throwaway line in this business. Unplanned outages at large renewable refineries wreck a quarter fast, and Neste kept its plants running when it mattered.

The hole it climbed out of

To understand why 266 million euros counts as a swing back, look at where the year started. The nine-month comparable EBITDA for Renewable Products came in at 512 million euros, barely ahead of the 500 million euros over the same stretch of 2024, even though volumes were higher. Do the arithmetic: most of that full-period figure was earned in the third quarter alone. The first half was close to a washout.

The cause was oversupply. Renewable diesel and SAF ran at tight-to-negative margins through much of 2025 as too much product chased too little demand, and the International Energy Agency projected that combined US biodiesel and renewable-diesel use would fall roughly 20 percent on the year. Cheap imported feedstock and used cooking oil, uncertainty over US tax credits, and a glut of new capacity all pressed down on prices at once. Several producers cut runs or idled plants. Neste took the pain too, then leaned on cost cuts and its SAF ramp to grind back to profitability.

Betting on renewables while others pull back

Neste is expanding while much of the industry retreats. Its Martinez Renewables joint venture with Marathon Petroleum in California reached full capacity of 730 million gallons a year during 2025. The Rotterdam growth project, due on stream in 2027, is set to become one of the world's largest producers of renewable diesel and SAF, adding around 1.3 million tons of annual capacity and pushing Neste's SAF output toward 2.2 million tons a year. The company still targets helping customers cut greenhouse-gas emissions by 20 million tons a year by 2030.

That expansion runs against the grain. Traditional energy companies have walked back renewable commitments as high financing costs and thin returns made fossil projects look more attractive by comparison. Neste's answer is to build scale and integration so its cost per ton beats the pack, betting that when weak players exit and supply tightens, the survivors with the lowest costs take the margin. The third quarter is the first clean piece of evidence that the bet can pay.

Where the other segments landed

Renewable Products is the headline, but it was not alone. Oil Products contributed 232 million euros of comparable EBITDA in the quarter, helped by improving fuel demand in Europe, and Marketing and Services added 34 million euros. The blend across all three is what produced the record group profit. Neste held its full-year guidance, saying it still expects annual sales volumes in both its renewable and oil products businesses to come in above 2024 levels.

What to watch next

One strong quarter does not settle the oversupply question. The margin recovery leaned partly on European demand and on Neste's record SAF sales, and both need to hold. US policy is the wild card: the shape of the renewable volume obligations and the 45Z clean-fuel production credit will steer how much North American product competes for the same buyers in 2026. If the credit structure firms up in favor of domestic producers using domestic feedstock, import economics shift again.

For now, the read is straightforward. The worst of the 2025 biofuels squeeze appears to be behind the sector's largest independent producer, margins have room above the survival line, and SAF is turning into a real profit engine rather than a compliance cost. Neste spent the first half proving it could take a beating and keep spending on growth. The third quarter is the first sign that discipline is starting to pay off.
