Key Takeaways:

NEW YORK — Halper Sadeh LLC, an investor rights law firm, announced Monday it is investigating the merger of Pulmatrix, Inc. (NASDAQ: PULM) and Eos SENOLYTIX, Inc. The investigation centers on whether the proposed deal is fair to Pulmatrix shareholders.
The law firm encourages Pulmatrix shareholders to learn more about their rights and options by contacting Daniel Sadeh or Zachary Halper. The investigation was announced via a press release on April 13, 2026.
Under the terms of the agreement, Pulmatrix stockholders are expected to own approximately 6% of the combined company upon closing. The investigation by Halper Sadeh aims to determine if this valuation is adequate and if the board of directors is fulfilling its fiduciary duties to shareholders.
The probe introduces significant uncertainty surrounding the merger's completion and could lead to a renegotiation of terms or a lawsuit. Such events would likely increase volatility in Pulmatrix's stock price as investors await a resolution.
This investigation signals that the proposed ownership stake for Pulmatrix shareholders is potentially undervalued in the eyes of investor rights advocates. The next catalyst for investors will be any formal legal action taken by Halper Sadeh or a response from the boards of Pulmatrix or Eos SENOLYTIX.
