BIG SKY INDUSTRIAL INC. (BSIN) stock intrinsic value fair value estimate & owner earnings analysis

Big Sky Industrial (formerly U.S. Energy Corp., renamed June 8, 2026) is a small company in transition. It still owns about 209 net producing oil and gas wells, mostly in Montana, Wyoming, Oklahoma and Texas (about 371 barrels of oil equivalent per day in the second quarter of 2026, 78% oil, with one buyer taking 76% of first-half revenue). It is using that business and repeated share sales to build the Big Sky Carbon Hub on roughly 168,000 net acres over the Kevin Dome in Toole County, Montana. The hub's first plant is under construction: about 8 million cubic feet a day of inlet gas, about 14 million cubic feet a year of helium, and about 125,000 tonnes a year of carbon dioxide to be stored underground. Commissioning is targeted for late 2026 and first revenue for early 2027. On April 27, 2026 the company signed a five-year, 100% take-or-pay helium sale contract with an investment-grade industrial gas company at a fixed $285 per thousand cubic feet, rising with inflation from March 2028. Track record. In each of the last ten years the cash the business produced, after stock pay and the spending needed to keep production going, has been negative. It was about -$0.4 million in 2024 and -$6.8 million (-$0.20 a share) in 2025. The cause is overhead. General and administrative costs, including stock pay, have run $8-11.5 million a year since 2022 ($11.4 million annualized in the first half of 2026). The oil fields earn far less than that after field costs: about $1.6 million in 2025 and about $3.1 million annualized in the first half of 2026, after operating costs fell sharply. The 2025 reserve report values the proved oil and gas reserves at $16.7 million at $65 oil, and that value shrinks about 17% a year as the wells deplete. We treat spending on the Montana project as investment rather than upkeep. We assume the reserve report's future costs include plugging the wells, so we do not also deduct the $8.3 million plugging liability when the fields are assumed sold. Shares outstanding rose from 33.8 million (2025 average) to 52.5 million by August 2026, and the company can still sell up to $15.9 million more stock through its equity line. What the cases credit. The helium contract and the plant under construction are counted. The carbon-storage tax credit (about $130 million over 12 years by the company's figure) is counted only in the bull case. It requires EPA approval of two monitoring plans (Big Rose and Cut Bank) that is still pending. Federal rules also exclude carbon dioxide drawn from naturally occurring underground deposits, and Kevin Dome gas is mostly natural carbon dioxide. The filings do not say how the project qualifies. Phase 2 is not counted anywhere, as the company itself excludes it. The company has not disclosed the plant's total cost, operating cost or net revenue share. We assume about $15 million is still to be spent to finish it (the company says its $21.5 million of liquidity covers construction), about $3 million a year to run it, and that partners and royalty owners take 20% of the helium. Helium alone, at about $4 million a year gross, roughly covers running the plant. It does not cover the overhead. Base case: the plant starts in mid-2027 and sells helium under the contract, but there is no tax credit. Overhead continues at about $9.5 million a year for three years, after which the company must sell or wind down its assets. The business is worth about -$24 million. With $6.0 million of cash and $4.5 million owed on the bank facility, that is about -$0.44 a share. On these assumptions, running the company and finishing the plant would use up more than its assets are worth. The gap would be covered by issuing new shares, which would leave little for today's shareholders. Bear case: an oil price collapse like 2015-2016 halves oil prices for two years and leaves them 15% lower afterwards. The plant is a year late and runs at 60% of design, the tax credit is never obtained, construction overruns its funding by 20%, and overhead stays at the first-half 2026 rate until a forced sale. The business is worth about -$52 million against $4.5 million of debt and $6.0 million of cash, about -$0.96 a share. The company would need roughly $50 million more than its assets would fetch, raised at distressed prices. The bank facility matures May 31, 2029. Its debt-to-EBITDAX test is suspended only until March 31, 2027, and with negative cash flow it could not be met without new equity. Bull case: the plant starts on schedule in January 2027, both monitoring plans are approved, and the tax credit is earned for 12 years. The helium contract is renewed on similar terms and the plant costs about $2 million a year to run. The oil fields hold their second-quarter 2026 margins until they run out, and overhead falls back to the 2025 level. The business is worth about $4 million, after spending $10 million to finish the plant and paying to plug the wells. With $6.0 million of cash less $4.5 million of debt, that is about $0.11 a share. Even in this case, most of the hub's income goes to corporate overhead. Margin-of-safety price. We are fairly sure of the overhead, which has stayed high for four years, and of the shrinking oil fields. We are unsure of the plant's cost, how it performs and whether it qualifies for the tax credit. The worst plausible outcome is a plant that runs but does not qualify, at a company with negative cash flow, a bank test returning in 2027 and an equity line as its main funding. That ends in heavy dilution or restructuring. If we are wrong on the two biggest unknowns (tax-credit eligibility and plant running costs), the bull case shows the hub only just covers overhead. The company pays no dividend and keeps issuing shares. No price gives reasonable confidence of a 20% annual return, so no margin-of-safety price is set. That would change if the tax credit is approved and the plant's actual costs are reported, and those facts would be needed before revisiting. Previous figures. Our earlier estimate was based on the company's book value, which counts money spent on the Montana project at cost, so it is not comparable. Since then, the helium contract and plant construction, both now counted here, have been offset by higher overhead and continued share issuance.
