Rhea-AI Filing Summary

Voyager Therapeutics, Inc. President and CEO Alfred Sandrock reported an open-market sale of 11,732 shares of common stock of Voyager Therapeutics at a weighted average price of $3.41 per share.

After this tax-related sale, Sandrock directly holds 498,257 shares of Voyager Therapeutics common stock.

Insights

Equity compensation and insider-trading analyst

CEO’s non-discretionary tax sale has limited signaling impact.

The filing shows Voyager Therapeutics CEO Alfred Sandrock sold 11,732 shares of common stock at a weighted average of $3.41 per share. The footnote explains this was a pre-arranged “sell-to-cover” under a durable automatic sale instruction tied to RSU vesting on February 17, 2026.

Sell-to-cover transactions are typically executed to satisfy tax withholding when equity awards vest, rather than to adjust an economic stake. The filing further notes the sale was not a discretionary trade by the reporting person. After the sale, Sandrock still directly owns 498,257 shares, so his ongoing equity exposure to Voyager Therapeutics remains substantial.

Because this is a routine, tax-driven sale under an established instruction, it is generally viewed as an administrative consequence of equity compensation rather than a change in the company’s outlook. Subsequent company filings may provide additional context on future equity grants or vesting events.
