XFOR · X4 Pharmaceuticals, Inc · Short Interest
The latest filing states the doubt was alleviated.
“The Company has evaluated whether there are certain conditions and events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year after the date that the condensed consolidated financial statements are issued. Although the Company has an approved drug product, licensing and sales of the Company's drug product over the next 12 months will not be sufficient to fund the Company's operating expenses. Since inception, the Company has incurred significant operating losses and negative cash flows from operations, and the Company expects to continue to generate operating losses and negative cash flows from operations for the foreseeable future. For the six months ended June 30, 2026, the Company's net loss was $36.4 million and net cash used in operating activities was $40.4 million. As of June 30, 2026, the Company had $208.0 million of cash, cash equivalents and short-term marketable securities, and an accumulated deficit of $631.0 million. Based on its current operating plan, the Company believes (a) that its current cash, cash equivalents and short-term marketable securities will be sufficient to fund its operations and debt obligations for at least the next 12 months and (b) it will continue to comply with all covenants under the Hercules Loan Agreement, as defined and further described in Note 9, through at least the 12-month period from the issuance date of these condensed consolidated financial statements.”View the 10-Q filed Aug 6, 2026

Method and coverage limits
Factor percentiles compare eligible primary operating-company stocks reporting short interest at the latest settlement date (2026-08-31). 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.
Open interest is incomplete, stale, or dated inconsistently; positioning totals are unavailable.
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 2026-09-13 04:24 UTC. Options model values may come from a cached snapshot; their original computation time is not supplied. Open interest has its own effective date.
