FTC issues second request on Lantheus‑Curium merger

The Federal Trade Commission sent a second request for information to Lantheus and Curium on October 21, extending the Hart‑Scott‑Rodino waiting period. The companies said they will respond promptly and still expect the transaction to close in the first half of 2027, subject to regulatory approval. The deal is valued at $8 billion.

The additional FTC request lengthens the antitrust review, which could delay the merger beyond the originally anticipated first‑half‑2027 closing, affecting investors’ expectations for integration synergies.
