Rule of Law:
A merger that results in a high market share, creating a prima facie case of illegality under Section 7 of the Clayton Act, can be rebutted by evidence that low barriers to entry in the relevant market would prevent the merged firm from exercising market power and raising prices.
Facts:
- Waste Management, Inc. (WMI) was a large national company in the solid waste disposal business.
- WMI acquired EMW Ventures Incorporated (EMW), a holding company that owned Waste Resources, another waste disposal company.
- Both WMI and Waste Resources had subsidiaries operating in the commercial waste collection market in Dallas, Texas: WMI's American Container Service (ACS) and Waste Resources' Texas Industrial Disposal, Inc. (TIDI).
- The acquisition combined these two formerly competing Dallas-area subsidiaries under WMI's control.
- The relevant market was determined to be commercial and industrial waste collection in Dallas County.
- Starting a competing waste collection business in this market was found to be relatively easy, requiring minimal capital for a truck and containers, with individuals able to operate out of their homes.
- Existing waste hauling companies in the nearby city of Fort Worth could also readily enter the Dallas market if prices became supracompetitive.
Procedural Posture:
- The United States government filed an antitrust action against Waste Management, Inc. (WMI) and EMW Ventures Incorporated (EMW) in the U.S. District Court.
- The government sought to block WMI's acquisition of EMW, alleging a violation of Section 7 of the Clayton Act.
- The district court denied the government's motion for a temporary restraining order, and the acquisition was consummated.
- Following a bench trial, the district court held that the acquisition violated the Clayton Act with respect to the Dallas market.
- The district court entered an order requiring WMI to divest itself of Texas Industrial Disposal, Inc. (TIDI).
- WMI and EMW, as defendants-appellants, appealed the district court's judgment and divestiture order to the U.S. Court of Appeals for the Second Circuit.

Issue:
Does a merger that results in a combined market share of 48.8% violate Section 7 of the Clayton Act if the relevant market is characterized by low barriers to entry, allowing potential competitors to easily enter and constrain the merged firm's pricing power?
Opinions:
Majority - Winter, J.
No. A merger that creates a firm with a 48.8% market share does not violate Section 7 of the Clayton Act where low barriers to entry prevent the firm from exercising market power. Although the 48.8% market share is sufficient to establish a prima facie case of illegality under United States v. Philadelphia National Bank, this presumption is rebutted by the evidence of easy entry into the market. The court found that the trial court's factual determination that new competitors can easily enter the Dallas trash collection market was not clearly erroneous. This ease of entry, both by new entrepreneurs and by existing firms from nearby Fort Worth, means that any attempt by the merged entity to raise prices above competitive levels would be quickly thwarted by new competition. Therefore, the market share statistic is a misleading indicator of actual market power, and since the merged firm's power to control prices is insubstantial, the acquisition does not substantially lessen competition.
Analysis:
This decision is significant for establishing ease of entry as a powerful defense to rebut a prima facie case of a Clayton Act Section 7 violation based on market concentration statistics. It shifts the focus of merger analysis from a purely structural approach, based on market share, to a more functional one that considers actual market dynamics and the potential for competition. The ruling aligns with the Department of Justice's own Merger Guidelines, which recognize that low entry barriers can negate the anticompetitive effects of a merger. This case provides a foundational precedent for defendants in merger cases to argue that market share figures are misleading where potential competition can effectively discipline the behavior of incumbent firms.
