Brink's Company (BCO) stock experienced a sharp decline of 5.59% in after-hours trading, following the announcement of a major acquisition and the release of its quarterly financial results.

The plunge appears to be driven by investor reaction to Brink's agreement to acquire NCR Atleos in a cash-and-stock transaction valued at approximately $6.6 billion. The deal, which includes the assumption of about $2.6 billion of NCR Atleos' debt, will be financed with a combination of cash on hand, new debt, and the issuance of 13.3 million shares of Brink's common stock. While the company expects the acquisition to be accretive to earnings, the significant size of the transaction and the associated increase in leverage may have raised concerns among shareholders.

Concurrently, Brink's reported fourth-quarter adjusted earnings that surpassed analyst estimates, with revenue also coming in above expectations. The company provided guidance for the first quarter that was largely in line with or slightly above consensus. However, the market's focus in the extended session seems to have shifted to the implications of the large acquisition announcement.
