Dew, behave yourself! Share re-purchase doth not equal M&A.
Actually, it does. On the scale we’re talking about—tens of billions of dollars in a short time—companies such as PFE and MRK could not simply buy their shares on the open market. Such a transaction would have to be accomplished by a formal tender offer with an SEC-filed prospectus and a procedure identical in almost every respect to an acquisition of another company’s shares.
