In a notable series of transactions, Sheldon Sloan, serving as the Chief Medical Officer for Spyre Therapeutics, Inc. (NASDAQ:SYRE), liquidated common stock valued at roughly $5.60 million on May 1, 2026. The divestment involved a total of 78,333 shares, with individual sale prices fluctuating between $69.21 and $75.37 per share.
The timing of this sale coincides with the company's stock trading in close proximity to its 52-week high of $76. This follows a period of intense upward momentum, as the stock has climbed by 359% over the last twelve months. Analysis suggests that at these current price levels, where shares trade at 10.7 times book value, the stock may be considered overvalued.
Transaction Details and Execution
The sales were conducted under a Rule 10b5-1 trading plan, which Sloan had established on June 20, 2025. This regulatory framework allows for pre-planned transactions to avoid conflicts regarding non-public information. The liquidation was executed through several distinct tranches at varying weighted average prices:
- 21,306 shares were sold at a weighted average of $69.53 per share.
- 19,656 shares were sold at a weighted average of $70.61 per share.
- Subsequent portions were sold at weighted average prices of $71.56, $72.94, $73.74, and $74.60.
- A final block of 400 shares was sold at a price of $75.37 per share.
Prior to the sale, Sloan had acquired these 78,333 shares by exercising stock options at an exercise price of $27.46 per share, a move that cost approximately $2.15 million. These options were part of a broader grant for 400,000 shares. Under the terms of that grant, one quarter was set to vest and become exercisable on October 1, 2025, with the remaining three quarters scheduled to vest in monthly increments over the following three years, contingent upon Sloan's continued employment with the company.
Following the completion of these transactions, Sloan holds zero direct shares of Spyre Therapeutics common stock. However, he maintains a position in derivative securities, which grant him the right to purchase 321,667 shares of common stock, with an expiration date of October 1, 2034.
