Explanatory Note

On January 10, 2025, IGM Biosciences, Inc. (the “Company”) filed a Current Report on Form 8-K (the “Original Form 8-K”) disclosing a strategic update to halt further development of imvotamab, an IGM-based CD20 X CD3 bispecific antibody T cell engager, and IGM-2644, an IGM-based CD38 X CD3 bispecific antibody T cell engager, for autoimmune diseases, including an approximately 73% reduction in force to preserve cash (the "2025 Restructuring").

At the time of the filing of the Original Form 8-K, the Company was unable in good faith to make a determination of an estimate or range of estimates required by paragraphs (b), (c) and (d) of Item 2.05 of Form 8-K with respect to the 2025 Restructuring. This Amendment No. 1 to the Original Form 8-K (the “Amendment”) is being filed by the Company to provide such information. Except as set forth herein, the remainder of the Original Form 8-K is unchanged.

Item 2.05 Costs Associated with Exit or Disposal Activities.

As a result of the 2025 Restructuring, the Company estimates it will incur total restructuring charges between $0.7 million and $2.0 million, consisting of cash expenditures between $4.1 million and $5.4 million for severance and one-time termination costs offset by non-cash compensation and stock-based compensation expense credit of $3.4 million. The Company expects to recognize substantially all restructuring charges in the first quarter of 2025.

The estimates of costs and expenses that the Company currently expects to incur in connection with the 2025 Restructuring are subject to a number of assumptions, and actual results may differ materially. The Company may also incur additional costs due to events that may occur as a result of, or that are associated with, the 2025 Restructuring.
