As a result of the Merger, Cigna and Express Scripts became direct wholly owned subsidiaries of New Cigna. As a result of the transactions contemplated by the Merger Agreement, New Cigna became a publicly traded corporation, and former Cigna stockholders and former Express Scripts stockholders received common stock of New Cigna.

Also at the Effective Time, Cigna’s name was changed from “Cigna Corporation” to “Cigna Holding Company” and New Cigna’s name was changed from “Halfmoon Parent, Inc.” to “Cigna Corporation.”

At the Effective Time, each issued and outstanding share of Cigna common stock, par value $0.25 per share (other than shares of Cigna common stock held (a) by Cigna as treasury shares or (b) by New Cigna or Merger Sub 1), was converted automatically into one share of New Cigna common stock.
