SEC remarks

On August 7, 2026, Wave Life Sciences, Inc., a Delaware corporation, became the successor of Wave Life Sciences Ltd., a company organized under the laws of the Republic of Singapore ("Wave-Singapore"), pursuant to a scheme of arrangement under Singapore law under which all issued ordinary shares in the capital of Wave-Singapore were exchanged on a one-for-one basis for shares of common stock of Wave Life Sciences, Inc. (the "Redomiciliation"). The Redomiciliation had the effect of changing Wave-Singapore's domicile, but did not alter the proportionate interests of securityholders. Exhibit 24.1 - Power of Attorney
