IGM Biosciences, Inc.

Johnson Fistel Investigates Fairness of Proposed Sale of IGM Biosciences

Shareholder rights law firm Johnson Fistel, PLLP has launched an investigation into whether the board members of IGM Biosciences, Inc. (NASDAQ: IGMS) breached their fiduciary duties in connection with the proposed sale of the Company to Concentra Biosciences, LLC.

Background:

  • On July 1, 2025, IGM Biosciences announced it had entered into a definitive merger agreement with Concentra Biosciences, LLC.
  • Under the terms of the proposed transaction, IGM shareholders would receive $1.247 in cash per share, plus one non-tradeable contingent value right (CVR).
  • The CVR entitles shareholders to additional proceeds under certain circumstances, though the specific conditions and value of these potential payouts remain uncertain.
  • The deal comes at a time when IGM shareholders may question whether the board secured the best possible consideration, especially given the lack of transparency around the valuation of the CVR and IGM’s long-term value potential.

What this means for IGM Biosciences shareholders:

  • The fixed cash component of $1.247 per share may undervalue IGM’s long-term potential.
  • The CVR structure introduces uncertainty and may not adequately compensate shareholders for the full value of their shares.
  • Shareholders may be left with insufficient consideration for their investment if the terms of the CVR are not clearly disclosed or ultimately do not pay out.

If you own IGM Biosciences shares and believe this proposed deal undervalues your investment, please consider joining our investigation.

If you are a shareholder of IGM Biosciences and believe the proposed buyout price is too low or you’re interested in learning more about the investigation, please contact lead analyst Jim Baker (jimb@johnsonfistel.com) at 619-814-4471. If emailing, please include a phone number.
