("Jade" or the "Company") (NASDAQ:JBIO), a clinical-stage biotechnology company focused on developing best-in-class therapies for autoimmune diseases, today announced that Jade's Board of Directors granted an equity award to Edward R. Conner, M.D., effective as of April 22, 2026, in connection with his appointment as Chief Medical Officer.

The Board of Directors granted Dr. Conner non-qualified stock options to purchase an aggregate of 500,000 shares of the Company's common stock under the Jade Biosciences, Inc.

The option grant was granted as an inducement material to Dr. Conner entering into employment with Jade in accordance with Nasdaq Listing Rule 5635(c)(4).

The Inducement Plan is used exclusively for the grant of equity awards to individuals who were not previously employees of Jade, or following a bona fide period of non-employment, as an inducement material to such individuals' entering into employment with Jade, pursuant to Nasdaq Listing Rule 5635(c)(4).

The stock options have an exercise price of $25.38 per share, which is equal to the closing price of Jade's common stock on The Nasdaq Global Market on April 22, 2026. The shares subject to the stock options will vest over four years, with 25% of the shares vesting on the one-year anniversary of the applicable vesting commencement date and the balance vesting in 36 successive equal monthly installments thereafter, subject to Dr. Conner's continued employment with Jade on such vesting dates.

The Company intends to file a registration statement on Form S-8 with the U.S. Securities and Exchange Commission to register the shares of common stock issuable under the Inducement Plan.

The award is subject to the terms and conditions of the Inducement Plan and the applicable award agreement.
