The company's stock price has been highly volatile since the DOJ disclosures, and the pending litigation adds further uncertainty. For example, Semler Scientific's revenue declined 43.19% year-over-year in Q2 2025, despite a net margin of 814.57%, raising questions about its long-term sustainability Semler Scientific Faces Class Action Amidst Declining Revenue and Increasing Profitability Concerns, [https://csimarket.com/news/semler-scientific-faces-class-action-amidst-declining-revenue-and-increasing-profitability-concerns2025-09-08085706]^[7].

For shareholders, the November 28, 2025, deadline is not merely a procedural milestone but a critical opportunity to secure legal recourse.
