Director at Precision BioSciences (DTIL) sees 21,000 RSUs vest into common stock

Rhea-AI Filing Summary

PRECISION BIOSCIENCES INC director Stanley Frankel reported the vesting of equity awards, rather than an open-market trade. On May 20, 2026, 21,000 Restricted Stock Units (RSUs) converted into the same number of shares of common stock at an exercise price of $0.00 per share.

These RSUs were originally granted on June 3, 2025 and vested based on continued service and the timing of the company’s next annual stockholders’ meeting. Following this vesting event, Frankel directly holds 40,478 shares of Precision BioSciences common stock. The filing does not show any same-day sale of these shares, so this appears to be a routine compensation-related equity vesting and exercise.
