It receives notifications of proposed mergers and acquisitions that reach the threshold under the Implementing Rules and Regulations of the Philippine Competition Act, as well as cases referred to it by the Commission for a motu proprio review. The Office, works together with the Economic Office to investigate whether mergers and acquisitions are likely to result in a substantial lessening of competition in the market. Should it find that a merger or acquisition is likely to reduce competition and harm consumers through higher prices, lower quality of goods or services, or stifle innovation, it will submit a recommendation to the Commission for the proposed transaction’s prohibition.
