ASPI ASP Isotopes Inc.
Price Chart
Executive Summary
Director and officer Paul Elliot Mann filed a Form 144 notice of intent to sell 251,275 shares of ASP Isotopes common stock, with an aggregate market value of approximately $1.95 million based on the May 29, 2026 closing price of $7.78. The shares were acquired as compensation via a restricted stock award on May 28, 2026, and the sale is explicitly for satisfying tax liabilities from the quarterly vesting of a 2,233,555-share award. This is a routine tax-motivated sale by an insider, not a discretionary portfolio liquidation.
Actionable Insight
This is a tax-motivated insider sale tied to a large restricted stock vesting, not a discretionary reduction. The 251,275-share filing is modest relative to the 2.2M-share award and the company's float. Monitor for actual execution on Form 4, but no bearish signal here — the insider is simply covering a tax obligation.
