Amgen-Horizon Takeover Seen Close to a Lock After FTC Pauses Challenge

Traders are almost 100% certain that Amgen Inc. will complete its $28 billion takeover of Horizon Therapeutics Plc after the Federal Trade Commission paused its in-house case to block the deal.

(Bloomberg) — Traders are almost 100% certain that Amgen Inc. will complete its $28 billion takeover of Horizon Therapeutics Plc after the Federal Trade Commission paused its in-house case to block the deal.

Horizon shares jumped 5.1% on Monday to $112.15 following the antitrust regulator’s late Friday order, which allows Amgen and Horizon to propose a settlement that would negate the need for further litigation. The surge leaves Horizon stock roughly $4 below Amgen’s $116.50 offer, the narrowest spread on a closing basis since May, and down from a gap of nearly $10 at Friday’s close.

The pricing indicates the market sees more than a 90% probability that the deal will close, up from 70% to 80% over the last several weeks, according to Brett Buckley, an event-driven strategist at WallachBeth Capital. 

Although many merger-arbitrage investors expected the deal to close whether or not it went to court, “it is highly likely it will close sooner now,” Buckley added.

The FTC sued in May to block the proposed tie-up, which was announced in December, arguing it would limit competition for the development of treatments for serious illnesses. It was the first challenge to a pharmaceutical deal in more than a decade. 

The latest move also sends a positive signal for Seagen Inc.’s pending $43 billion acquisition by Pfizer Inc., which is currently in the crosshairs with a second FTC request underway. Seagen gained 3.2% on Monday to about $206, compared with the takeover offer price of $229 per share. 

Should FTC reach a settlement on the Horizon-Amgen deal, it “could improve the tone on broader M&A activity in the sector,” Gregory Renza, an analyst at RBC Capital Markets, said in a research note. 

Horizon is one of the most widely held positions for merger-arbitrage traders. While the FTC’s block stunned many hedge funds and deal speculators, they continued to bet the companies would win in the dispute. In a July Bloomberg survey, 14 of 15 merger-arb market participants polled said they expected the deal to ultimately go through.
