Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On June 6, 2025, IGM Biosciences, Inc. (the “Company”) received written notice (the “Notice”) from The Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company is no longer in compliance with the minimum Market Value of Listed Securities (“MVLS”) of $50,000,000 required for continued listing on The Nasdaq Global Select Market, as set forth in Nasdaq Listing Rule 5450(b)(2)(A) (the “MVLS Requirement”). The Notice has no effect at this time on the listing of the Company’s common stock (the “Common Stock”), which continues to trade on The Nasdaq Global Select Market under the symbol “IGMS”.

In accordance with Nasdaq Listing Rule 5810(c)(3)(C), the Company has a period of 180 calendar days, or until December 3, 2025 (the “Compliance Date”), to regain compliance with the MVLS Requirement. To regain compliance, the Company’s MVLS must close at $50,000,000 or more for a minimum of 10 consecutive business days prior to the Compliance Date. In the event the Company does not regain compliance with the MVLS Requirement prior to the Compliance Date, Nasdaq will notify the Company that its securities are subject to delisting, at which point the Company may appeal the delisting determination to a Nasdaq hearings panel.

The Company intends to actively monitor its MVLS and may, if appropriate, consider implementing available options to regain compliance with the MVLS Requirement. The Company may also choose to transfer the listing of its Common Stock to The Nasdaq Capital Market. There can be no assurance that the Company will be able to regain compliance with Nasdaq Listing Rule 5450(b)(2)(A), or maintain compliance with any other listing requirements, or satisfy the requirements necessary to transfer the listing of its Common Stock to The Nasdaq Capital Market.
