Key Highlights

● Schneider Electric agreed to buy PTC for $205 a share.

● McKesson and Clayton Dubilier & Rice will take Option Care private.

● C.H. Robinson agreed to buy RXO.

● Records in stocks give buyers valuable shares to use.

Deal-making has picked up sharply. On Monday, Oct. 5, Schneider Electric agreed to buy PTC (NASDAQ:PTC), the US industrial software company, for $205 a share in cash, a transaction valued at about $22.6 billion. On Tuesday, Oct. 6, McKesson (NYSE:MCK) and private-equity firm Clayton Dubilier & Rice agreed to take Option Care Health (NASDAQ:OPCH) private for $32.05 a share in cash, valuing the home and alternate-site infusion provider at about $5.8 billion including debt.

Option Care shares rocketed to about $31, just below the offer price. The gap between the trading price and the cash offer is typical: it reflects the time until closing, expected in the first half of 2027, and the risk that a deal does not close.

PTC drew a wave of rating changes on Tuesday. BMO Capital (NYSE:BMO) downgraded the stock to Market Perform and Oppenheimer moved it to Perform, a common step once a cash price effectively caps further upside. Schneider's US-traded shares fell after JPMorgan (NYSE:JPM) downgraded the French company to Neutral.

A crowded calendar beneath the headlines

The pace extended well beyond the two largest deals. C.H. Robinson (NASDAQ:CHRW) agreed to buy freight broker RXO (NYSE:RXO), whose shares jumped on Oct. 5 and slipped back early Tuesday as some traders took profits. RXO also attracted a mix of rating changes: JPMorgan and TD Cowen upgraded it, while BMO and Jefferies (NYSE:JEF) downgraded it.

In banking, TowneBank (NASDAQ:TOWN) agreed to acquire blueharbor bank for about $154 million, paying $12.70 in cash plus 1.0534 TowneBank shares for each blueharbor share. "We are excited to welcome blueharbor and its talented team to the TowneBank family," said Executive Chairman G. Robert Aston, Jr.

Repligen (NASDAQ:RGEN)'s pending purchase of BioLife Solutions (NASDAQ:BLFS) is prompting an index change, with Freshworks (NASDAQ:FRSH) set to replace BioLife in the S&P SmallCap 600 on Oct. 8. In media, the newly merged media company Skydance (SKYD) made its market debut.

Some deals are still being fought over. A report said Seagate (NASDAQ:STX) and Toshiba are competing to buy TDK's hard-drive magnetic-heads business, and Seagate shares tumbled on concern about the potential cost and on Toshiba's capacity plans. Not every deal survives: B&G Foods (NYSE:BGS) and Nortera Foods ended an agreement for Nortera to buy Green Giant Canada after failing to win approval under Canada's competition rules.

Why buyers are moving now

Several forces line up. Stock prices are at records, giving acquirers valuable shares to use and boards confidence to act. The S&P 500 rose 44.98 points to a record 7,818.93 on Tuesday, and the Nasdaq Composite closed at a record just under 27,600. Large companies are also seeking growth in areas such as industrial automation software and specialized health services.

Financing is the main headwind. The Federal Reserve lifted its target range to 3.75 to 4.00 in September, and the 10-year Treasury Yield touched its highest since 2002 on Oct. 1 before easing to about 5.28 on Tuesday. Cash-rich strategic buyers can generally absorb those costs more easily than heavily leveraged ones, and McKesson is bringing a strategic stake alongside its private-equity partner in the Option Care deal.

What it means for markets

Takeovers pull shares out of public markets and adjust index weightings. They also generate advisory fees that show up in bank earnings.

Filings, Votes and Rival Bids Decide Which Deals Close

Regulatory filings and Shareholder votes for the PTC and Option Care deals will set their timelines. Investors will watch whether Seagate pursues the TDK unit and whether more bids emerge in health care and software. Big-bank results on Oct. 13 should offer commentary on the strength of the deal pipeline.
