restricted stock unit award (RSU) financial

"granted this restricted stock unit award (RSU)"

beneficial ownership regulatory

"disclaims beneficial ownership of the shares held"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

pecuniary interest financial

"except to the extent of his pecuniary interest therein"

shared voting and investment power regulatory

"may be deemed to have shared voting and investment power"

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
