The largest dollar stake in VSTM belongs to BlackRock, Inc., but the position matters far more to Stonepine Capital Management, LLC, who has 6.0% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

Smart Money Convergence

VSTM does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Verastem (VSTM) amended its debt deal with Oberland Capital on Aug. 6, 2026, splitting the facility into $75 million of existing Initial Notes and a new Revenue Notes series that can fund up to another $75 million, replacing earlier conditional loan tranches. Instead of fixed interest, the Revenue Notes carry quarterly payments equal to 4.50% of net sales of any product combining avutometinib and defactinib; the rate falls to 1.75% after Dec. 31, 2031 if cumulative payments have reached 100% of the funded amount, otherwise a one-time make-whole payment is owed. The notes mature June 30, 2033, and early redemption triggers repayment amounts from 135% to 185% of the funded amount depending on timing and reason, with the obligations secured by substantially all of the company's assets including related IP. The excerpt cuts off mid-sentence, so any remaining terms in the filing are not reflected here.
