Top officer leaving

8-K on sec.govFrom the company's 8-K, 10-K and 10-Q filings over the last two years. A flag is a reason to read the filing, not a verdict: many departures are planned retirements and many listing notices are resolved. Insider sales are shown for timing only; they are separate filings.
Short sale volume: 42.6% of the volume reported to FINRA over the last 20 trading days was marked short, close to its 1-year average of 41.3%. FINRA daily files, to Oct 2, 2026.
Fails to deliver: 79K shares (about $2.55M) were not delivered on time for settlement on Sep 1, 2026. SEC fails-to-deliver data.
Short sale volume is not short interest. It counts trades marked short, including market makers selling short to fill buy orders, so it is a share of daily trading, not a count of bets against the stock. Fails to deliver have many causes, including processing delays, and are often resolved within days.
