Performance-Based Equity Incentive Award for Chief Executive Officer

On December 20, 2023 (the “Grant Date”), Legend Biotech Corporation (the “Company”) granted to Ying Huang, the Company’s Chief Executive Officer, a performance-based restricted share unit award for up to 1,599,732 shares of the Company’s ordinary shares, par value $0.0001 per share, pursuant to the Company’s 2020 Restricted Shares Plan (the “RSU Grant”).

The RSU Grant is eligible to vest over a 5-year period on each anniversary of the Grant Date in accordance with the following schedule, subject to the Chief Executive Officer’s continued service on each vesting date:

The percent of the Target RSUs that will vest on each vesting date is subject to the Chief Executive Officer’s performance relative to the Company’s goals as determined by the Company’s board of directors (the “Board”) and compensation committee of the Board. If Dr. Huang is deemed to “Exceed Expectations”, perform “At Target” or perform at “Minimum Acceptable Performance” for a given year, then 120%, 100% or 50% of the applicable Target RSUs will vest for such year.    

Because the vesting of the RSU Grant is linked to and contingent upon achievement of the Company’s key long-term goals, the Company’s Board believes that the RSU Grant increases the alignment between the interests of Dr. Huang and the Company’s shareholders.

This report on Form 6-K is hereby incorporated by reference in the registration statements of the Company on Form F-3 (Nos. 333-272222, 333-257609 and 333-257625) and Form S-8 (No. 333-239478).
