Forward Air’s Amended Agreement to Acquire Omni Logistics, Resolving Previously Announced Litigation

On January 22, 2024, Forward Air Corporation (“Forward”) announced an agreement with Omni Logistics, LLC (“Omni”), a private company that is majority owned by Ridgemont Equity Partners and EVE Partners, LLC, to amend the terms of the existing merger agreement relating to their previously announced acquisition. This agreement ends the litigation between the parties, which will now be dismissed.

Cravath is representing Forward in connection with the transaction and related litigation.

Forward Air’s Amended Agreement to Acquire Omni Logistics, Resolving Previously Announced Litigation

On January 22, 2024, Forward Air Corporation (“Forward”) announced an agreement with Omni Logistics, LLC (“Omni”), a private company that is majority owned by Ridgemont Equity Partners and EVE Partners, LLC, to amend the terms of the existing merger agreement relating to their previously announced acquisition.

Under the terms of the amended merger agreement, Omni shareholders will receive $20 million in cash, instead of the $150 million initially agreed, and 35% of Forward’s pro forma common equity (on a fully‑diluted, as‑converted basis), as compared to the 37.7% of Forward’s pro forma common equity (on a fully‑diluted, as‑converted basis) contemplated by the original agreement. Cravath is representing Forward in connection with the transaction and related litigation.
