On May 24, 2026, Viridian Therapeutics, Inc. (the "Company") entered into a Commercial Manufacturing Services Agreement (the "Agreement") with WuXi Biologics (Hong Kong) Limited ("WuXi Biologics") pursuant to which WuXi Biologics will manufacture and supply the Company's anticipated long-term supply requirements of veligrotug drug substance and drug product for commercial use (the "Product"), if approved. Wuxi Biologics will be a non-exclusive supplier of the Product to the Company and the Company may procure the Product from one or more alternate manufacturers of the Product.

Under the Agreement, the Company will provide rolling forecasts of volume requirements to WuXi Biologics on a monthly basis (each, a "Forecast"). A portion of each Forecast will be considered a binding and non-cancellable commitment of the Company. The parties have agreed to volume-based pricing under the Agreement. The Product service fee will remain fixed until December 31, 2026 and thereafter may be annually adjusted based on a volume-based structure. The Company will also reimburse WuXi Biologics for certain pass-through costs.

The Agreement has an initial term of five years and will automatically renew for successive five-year periods unless either party provides notice of non-renewal at least 24 months prior to the expiration of the initial term or any renewal period. The Company may terminate the Agreement upon 30 days' prior notice to WuXi Biologics if there is a change in applicable laws that materially and adversely impacts WuXi's Biologics ability to perform services under the Agreement. Additionally, each party may terminate the Agreement upon an uncured material breach of the Agreement by the other party or upon the other party's insolvency or bankruptcy.

The Agreement contains customary provisions relating to, among other things, delivery, quality, change procedures, regulatory compliance, confidentiality, dispute resolution, warranties, and indemnification.

The foregoing description of the terms of the Agreement is not complete and is qualified in its entirety by reference to the text of the Agreement, a copy of which the Company intends to file as an exhibit to its Quarterly Report on Form 10-Q for the period ended June 30, 2026.
