Explanatory Note

This Registration Statement on Form S-8 is filed to register the offer and sale of (i) an additional 1,500,000 shares of the Registrant’s common stock, $0.0001 par value per share (the “Common Stock”), to be issued under the Registrant’s 2024 Inducement Plan, as amended (the “Inducement Plan”), and (ii) an additional 500,000 shares of Common Stock to be issued under the Registrant’s 2016 Employee Stock Purchase Plan (the “2016 ESPP”).

On December 4, 2025, the board of directors of Intellia Therapeutics, Inc. (the “Registrant”) approved an amendment to the Inducement Plan pursuant to which the Registrant reserved an additional 1,500,000 shares of Common Stock to be used exclusively for grants of equity-based awards to individuals who were not previously employees or directors of the Registrant, as an inducement material to the individual’s entry into employment with the Registrant within the meaning of Rule 5635(c)(4) of the Marketplace Rules of the Nasdaq Stock Market. The Inducement Plan provides for the grant of equity-based awards in the form of nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, unrestricted stock awards, and dividend equivalent rights. The Inducement Plan was adopted by the Registrant’s board of directors without stockholder approval pursuant to Rule 5635(c)(4) of the Marketplace Rules of the Nasdaq Stock Market.

On January 1, 2026, pursuant to the terms of the 2016 ESPP, the Annual Increase (as defined in the 2016 ESPP), comprising 500,000 shares of Common Stock, was added to the reserve available for issuance under the 2016 ESPP.
