On September 15, 2026, three 10% owners of LifeStance Health Group, Inc. (LFST) executed significant sales of the company's stock. James G.

The aggregate value of these sales amounts to roughly $678.77 million.

These substantial transactions by major stakeholders occurred on September 11, 2026.

The reported sales follow other insider transactions in August and early September, though at considerably smaller volumes.
