CLMT · Calumet, Inc.

The thesis

Calumet's case rests on a much cheaper expansion of sustainable aviation fuel (SAF) output at its Montana Renewables subsidiary. The company's 1 September 2026 plan calls for an annual SAF run-rate above 80 million gallons by year-end 2026 for $137 million of remaining capital. The third-quarter report on 6 November 2026, a date Calumet confirmed in a 6 October 2026 release, is the next public check on that cost and timetable.

Since the last update the company has confirmed the report date and set a 9:00 a.m. ET conference call for the same day. It has issued no new operating or financing news since the 14 September 2026 financing release. Zacks Research upgraded the shares to strong-buy from hold (MarketBeat, 7 October 2026). The other targets have not moved since early September. The outside pressure is unchanged. On 2 October 2026 diesel prices fell sharply after the Financial Times reported that the European Union was considering releasing 50 million barrels of diesel (Benzinga, 2 October 2026). That weighs on Calumet's conventional fuels business, not on the renewable plan.

The narrative is maturing: the September news run (the redesign on 1 September 2026, exemption relief on 2 September 2026, the final federal loan draw on 14 September 2026) is well known, and the only new items in October are a date confirmation and a quantitative-model upgrade. The shares closed at $57.75 on 8 October 2026, 2.2% below the $59.05 52-week closing high and 45.9% higher over three months. Calumet trades as a legacy refiner converting existing equipment into renewable-fuel capacity. Policy credits and compliance rulings move the shares as much as plant output does.

Bullish and bearish views on Calumet, Inc.

The bull case on Calumet, Inc. (CLMT), in brief: The expansion needs far less capital. The bear case: The company still loses money.

Bull case

• The expansion needs far less capital. The 1 September 2026 plan cut remaining project capital to $137 million from the $1.2 billion of the original second phase. Management said the redesign captures about 70% of the originally expected benefit for about 15% of the originally expected capital.
• The longer path has numbers attached. The same 1 September 2026 release targets about 200 million gallons a year of SAF by year-end 2028. The run-rate was 60 million gallons a year as of spring 2026.
• This stage of the project is funded. Calumet said on 14 September 2026 that Montana Renewables took its final $34 million Department of Energy loan draw. Revolving-credit commitments rose to $600 million, maturing January 2031.
• The compliance relief has a defined size. Calumet's 2 September 2026 update reported exemptions that removed 71 million Renewable Identification Numbers (RINs) for the 2025 compliance year, a liability valued at about $170 million.
• Estimate momentum has turned up. Zacks Research moved the shares to strong-buy from hold (MarketBeat, 7 October 2026). HC Wainwright holds a Buy rating and a $75 target, raised from $60 on 2 September 2026.

Bear case

• The company still loses money. Second-quarter results on 7 August 2026 showed earnings per share of negative $1.09, against a consensus estimate of positive $0.07. Revenue rose 40.8% year over year to $1.45 billion.
• The price is above the consensus target. The $57.75 close of 8 October 2026 is above the $51.75 consensus target, which carries a Hold rating (MarketBeat, 8 October 2026). UBS ($47, neutral, 25 August 2026) and TD Cowen ($40, hold, 12 August 2026) sit well below the price.
• The year-ago quarter is a hard comparison. Calumet reported third-quarter 2025 net income of $313.4 million, or $3.61 per basic share, on 7 November 2025. That period included large exemption-related gains.
• Diesel prices turned lower. The FT report of 2 October 2026 on a possible European diesel release sent diesel prices sharply lower (Benzinga). President Trump had asked for at least 100 million barrels, and refining groups urged him on 23 September 2026 to reject any ban on US diesel exports.

Price setup

The shares closed at $57.75 on 8 October 2026, up 2.6% on the day and 2.2% below the $59.05 52-week closing high. MarketBeat listed the 50-day moving average at $50.99 and the 200-day moving average at $40.58 on 8 October 2026, so the price sits well above both rising averages. The 14-day relative strength index stood at 45.3 on 8 October 2026, a neutral reading after the September run.

The close of $52.38 on 30 September 2026 is the nearest recent low and sits just above the 50-day average. UBS's $47 target lies below both. A weekly close under $47 would put the shares back below the level where they traded before the September news run.

Crowding is moderate. The gap above the 200-day average is wide, the price exceeds the consensus target, and the earnings date is four weeks away. Institutional investors hold 34.41% of the shares (MarketBeat, 8 October 2026). No insider sales or share issuance into the rally appear in company filings since the 14 September 2026 release.

Catalysts, next 30 days

• 6 November 2026 — Third-quarter 2026 results and 9:00 a.m. ET call. Confirmed by Calumet on 6 October 2026. The first report since the redesign shows spending against the $137 million plan, SAF volumes, the turnaround schedule and the effect of lower diesel prices on the fuels business.
• ~31 December 2026, est. Montana Renewables turnaround and equipment tie-in. The tie-in must land in the fourth quarter for the year-end run-rate goal to hold.
• 31 December 2026 — Year-end SAF run-rate checkpoint. The 1 September 2026 plan calls for an annual run-rate above 80 million gallons by this date.

What would change the view

The case breaks if the 6 November 2026 report discloses Montana Renewables spending above the $137 million remaining-capital plan, or moves the turnaround tie-in into 2027. It also breaks if the year-end 2026 SAF run-rate lands at or below 80 million gallons a year. A third-quarter loss per share as wide as or wider than the second quarter's negative $1.09 would show the fuels business is not carrying the company through the expansion.

On price, a weekly close below $47, UBS's target and under the $52.38 close of 30 September 2026, would end the thesis. A new EPA determination or court ruling imposing liability on the 2022-2024 exemption petitions would weaken it. A confirmed European diesel release of 50 million barrels or more would weaken it further.

What it trades with

Calumet's fuels segment moves with diesel cracks and with government action on diesel supply, the variable that hit the group on 2 October 2026. Montana Renewables moves with policy: 45Z clean-fuel production credit values, RIN prices, California Low Carbon Fuel Standard (LCFS) credits and SAF premiums. Those drivers tie the shares more to renewable-diesel and SAF producers and to small-refinery exemption rulings than to crude benchmarks.
