shares -15.2% vs prior quarter

13F holdings exceed the share count. This is normal for heavily shorted stocks: shares lent to short sellers are reported by the lender and again by whoever bought them. Related filers occasionally report the same position twice as well.

Share classes (cover page of the 10-Q filed 2026-08-14, as of 2026-08-11)

Each class is compared with its own share count; classes are not added together. A class that is not exchange-listed cannot be held by 13F filers.

Totals combine the ticked CUSIPs and update as you tick: common-stock classes by default; preferreds, notes, warrants and depositary shares are listed but not counted. "holders →" shows a single CUSIP on its own. Bonds are held as a principal amount, not shares. Options positions are never counted as holdings. 2 further CUSIPs map to this company (mostly bonds) but no 13F filer held them this quarter.

Source: SEC Form 13F-HR information tables for the quarter ending 2026-06-30 (filed within 45 days of quarter end; amendments applied; values normalised to dollars), the share count from the company's latest 10-K/10-Q XBRL cover page, and Schedule 13D/13G filings. Each row is a legal 13F filer as filed — related entities (e.g. Vanguard's advisers) are not merged. Retail brokerage accounts are not reported on 13F, so the remainder is mostly retail and insiders.
