Ligand Pharmaceuticals Announces Inducement Grants Under NASDAQ Listing Rule 5635(c)(4)

Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) today announced that effective August 1, 2022, Ligand's Board of Directors approved the grant of non-qualified stock option awards to purchase an aggregate of 90,073 shares of its common stock, 5,000 restricted stock units ("RSUs") and 4,000 performance stock units ("PSUs") (at the target level) to six non-executive employees. The options were granted on August 1, 2022, and the grant date for the RSUs and the PSUs will be the date on which Ligand files a Form S-8 Registration Statement to register the shares pursuant to Ligand's 2022 Employment Inducement Plan ("Inducement Plan").

The awards were granted under the Inducement Plan as employment inducement awards pursuant to 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 Ligand, or following a bona fide period of non-employment, as an inducement material to such individuals' entering into employment with Ligand, pursuant to Nasdaq Listing Rule 5635(c)(4).

The options have an exercise price of $89.70 per share, which is the closing price of Ligand's common stock on The Nasdaq Global Select Market on August 1, 2022. The stock options have a term of ten years and will vest over four years, with 12.5% of the shares vesting six months after the employee's commencement of employment and the balance of the shares vesting in 42 equal monthly installments thereafter, subject to the grantee's continued service on such vesting dates.

The RSUs will vest over three years on the first three anniversaries of the grantee's commencement of employment, subject to continued service through each applicable vesting date. The PSUs will vest based on the achievement of certain total shareholder return objectives and the completion of the contemplated spin-off of OmniAb, Inc. from Ligand. The number of shares earned under the PSUs may be up to 6,500 in the aggregate if maximum performance levels are achieved.
