AT&T Co looks to be on the brink of winning the long-fought battle to acquire NCR Corp: it has agreed to offer a share exchange valued at $110 at Friday’s closing price for its shares. NCR is jibbing that if AT&T’s shares fall before completion, its holders will not get full value, but the differences between the two no longer appear unbridgeable, and it seems likely that a deal will be wrapped up in days.
