Reflects the disposition in cash as contemplated by paragraph 7(1)(b) of the Income Tax Act (Canada) of 137,922 performance share unit awards originally granted to the Reporting Person under the Bausch Health Companies, Inc. 2014 Omnibus Incentive Plan on March 2, 2023, which, as previously reported on February 11, 2026, were earned, on February 9, 2026, upon certification by the Talent and Compensation Committee (the "Committee") of the Board of Directors of the Issuer of the level of achievement of the applicable performance metrics, but remained subject to service-based vesting. As disclosed in the Issuer's Current Report on Form 8-K filed with the Securities and Exchange Commission on March 2, 2026, the Committee subsequently took action to provide for the payment of such earned performance share unit awards in cash rather than Issuer common stock upon vesting.
