On July 24, 2026, the Board of Directors of Dorian LPG Ltd. (the “Company”), upon the approval and recommendation of the Company’s compensation committee, approved and adopted the Company’s Amended and Restated Executive Severance and Change in Control Severance Plan (the “Severance Plan”). The Severance Plan was amended to revise the definition of “Change in Control” to remove certain carve-outs to such definition that are no longer appropriate in view of the Company’s current shareholders. This definition is intended to be aligned with the definition of “Change in Control” contained in the Company’s Second Amended and Restated 2014 Equity Incentive Plan.

The foregoing description is qualified in its entirety by reference to the full text of the Severance Plan, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
