Jasper Therapeutics Announces 1-for-30 Reverse Stock Split
1-for-30 reverse split effective Nov 6, 2026; shares outstanding fall from about 33.3M to 1.11M, Nasdaq compliance push.
What this release says
Jasper Therapeutics will combine every 30 shares of its common stock into one share, effective November 6, 2026, with trading continuing on Nasdaq under JSPR. Ownership percentages stay the same, but the share count falls from about 33.3 million to about 1.11 million, and the share price is expected to rise in proportion. The release ties the split to keeping the stock listed on Nasdaq, and says it may not achieve that goal.
