The assistant answers from what GTLB has actually filed: 7 annual reports filed with the SEC, 117 Form 4 filings from the last year, 13F positions from the 1 tracked investor who hold it and 4 funds that hold it. Every figure in a reply links to the filing it came from, so an answer can be checked rather than believed.
Pressing one answers it here, from GTLB's filings and figures. One a day without an account; a free account has its own, and no card.
See every Form 4 GTLB insiders have filed, not the latest few.
Ten seconds, no card, and nothing to cancel.
