BCHT · Birchtech Corp. · Short Interest
The latest filing states the doubt was alleviated.
“As disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, the Company had previously identified conditions that raised substantial doubt about its ability to continue as a going concern. Subsequent to year end, on February 27, 2026 and March 17, 2026 (following the partial exercise of the underwriters’ overallotment option), the Company completed an underwritten public offering of its common stock and received aggregate gross proceeds of $16.4 million, before deducting underwriting discounts and commissions and offering expenses. Based on the net proceeds from the offering, together with the Company’s existing cash, anticipated revenues and additional cash inflows from its current operations, management believes that the Company has sufficient liquidity to fund its operations and meet its obligations for at least the next twelve months and that the conditions giving rise to the previously disclosed substantial doubt have been alleviated.”View the 10-Q filed Aug 13, 2026

Method and coverage limits
Factor percentiles compare eligible primary operating-company stocks reporting short interest at the latest settlement date (2026-09-15). The weighted mean uses short interest 30%, days to cover 20%, price vs VWAP 15%, short-volume trend 15%, short-interest change 10%, and fails-to-deliver 10%. Missing factors redistribute their weight; incomplete coverage is not evidence of low risk. Price, volume, and earnings boosts add 10 each, capped at 20.
Shares outstanding are not free float. Borrow fees, utilization, lendable supply, recalls, and dealer inventory are not measured. Short-sale volume does not measure the change in open shorts; fails to deliver are not a borrow-cost measurement; price vs VWAP does not establish short sellers' entry prices. Earnings can move prices in either direction.
The weights are judgment-based, not calibrated to future squeeze outcomes. The separate options assessment below does not change this universe ranking.
Options positioning & squeeze sensitivity
Nearest expiration after today within 30 calendar days; same-day expirations and later maturities are excluded.
No active listed options were found.
Open interest has both a buyer and a seller; it does not reveal dealer hedge direction. Gross gamma sums both calls and puts without netting and uses a local 1% price-change approximation. It measures sensitivity, not predicted buying or a squeeze probability.
Assessment prepared 2026-10-08 08:39 UTC. Options model values may come from a cached snapshot; their original computation time is not supplied. Open interest has its own effective date.
