FTC signals lawsuit to block Cintas' $5.5 billion UniFirst acquisition

The Federal Trade Commission announced it will file a lawsuit to stop Cintas Corp.'s proposed $5.5 billion purchase of UniFirst Corp. The regulator cited antitrust concerns over market share in the uniform and facility‑services market. Cintas shares fell about 6% and UniFirst shares dropped roughly 9% after the news. The deal spread widened to $77 as arbitrage investors reassessed the likelihood of closing.

The FTC action creates immediate downside pressure on both stocks, as investors price in the risk that the merger will not close. If the lawsuit succeeds, the transaction could be terminated, leaving UniFirst with weakened fundamentals and Cintas without the expected synergies.
