Rule of Law:
In a Clayton Act Section 7 merger challenge, a prima facie case based on market share and concentration statistics can be rebutted by evidence showing that those statistics do not accurately reflect the acquired firm's future ability to compete in the relevant market.
Facts:
- In 1954, Material Service Corp., a deep-shaft coal producer through its affiliate Freeman Coal Mining Corp., began acquiring stock in United Electric Coal Companies, a company that operated strip or open-pit mines.
- By 1959, Material Service had acquired over 34% of United Electric's stock, effectively gaining control of the company.
- Shortly thereafter, General Dynamics Corp. acquired Material Service, and through it, gained control of both Freeman and United Electric, becoming the nation's fifth-largest commercial coal producer.
- General Dynamics continued purchasing United Electric stock, and by 1966, it held over 66% of the shares, eventually making United Electric a wholly owned subsidiary.
- During this period, the coal industry's structure changed significantly, with electric utilities becoming the primary consumers of coal.
- Sales to utilities were increasingly governed by long-term requirements contracts, where coal producers commit their output for many years at predetermined prices.
- At the time of the lawsuit, virtually all of United Electric's proven and economically mineable coal reserves were either depleted or already committed under long-term contracts.
- United Electric lacked the ability to acquire new strip-mining reserves and did not have the expertise to develop deep-mining reserves.
Procedural Posture:
- The U.S. Government commenced a suit in the United States District Court for the Northern District of Illinois against General Dynamics Corp., alleging the acquisition of United Electric Coal Companies violated Section 7 of the Clayton Act.
- Following a trial, the District Court issued a judgment for the defendants, finding no violation of the Clayton Act.
- The Government appealed the District Court's decision directly to the Supreme Court of the United States.

Issue:
Does a court's analysis of a merger's legality under Section 7 of the Clayton Act depend solely on market share statistics, or may the court consider other evidence, such as the acquired company's weakened future competitive prospects, to rebut a prima facie case of anticompetitive effects?
Opinions:
Majority - Mr. Justice Stewart
No. While market share statistics can establish a prima facie case of a Clayton Act violation, they are not conclusive and can be rebutted by other evidence showing that the statistics do not accurately reflect the market's competitive realities. The Court reasoned that a merger must be 'functionally viewed, in the context of its particular industry.' In the coal industry, which had become dominated by long-term requirements contracts, a company's past production figures are not a reliable indicator of its future competitive strength. A more significant measure of competitive power is the state of a company's uncommitted reserves of recoverable coal. The evidence showed that United Electric's reserves were severely depleted and almost entirely committed under existing contracts, meaning its ability to compete for new long-term contracts in the future was 'severely limited and steadily diminishing.' This evidence of weakness as a future competitor successfully rebutted the government's prima facie case, which was based solely on past production statistics. The Court distinguished this analysis from the 'failing company' defense, noting the issue was not that United Electric would go out of business, but that it was no longer a significant competitive force in the market for future contracts.
Dissenting - Mr. Justice Douglas
Yes. The Court should have relied on the statistical evidence of increased market concentration at the time of the merger, which established a violation under prevailing precedent. The majority improperly considered post-acquisition evidence of United Electric's weakened reserve position, essentially applying a disguised and incorrectly formulated 'failing company' defense. The viability of the acquired company must be assessed at the time of the merger (1959), not at the time of trial. The District Court also erred by rejecting 'coal' as a relevant product submarket and by defining geographic markets too narrowly, ignoring the commercial realities of competition between the companies. The majority's departure from established reliance on market concentration statistics abdicates the Court's duty to enforce Section 7, and the case should have been remanded for proper findings based on the market conditions at the time of the acquisition.
Analysis:
This landmark decision significantly shifted merger analysis under Section 7 of the Clayton Act. It marked a departure from the Warren Court's heavy reliance on structural presumptions, where high market share statistics were nearly conclusive proof of a merger's illegality. By allowing defendants to rebut a statistical prima facie case with evidence of the acquired firm's poor future competitive prospects, the Court opened the door for more sophisticated economic and factual arguments. The 'General Dynamics defense' requires courts to look beyond mere numbers to the actual 'structure, history and probable future' of the market, making it more difficult for the government to win merger challenges based on statistics alone.
