Some observers believe Pfizer (PFE -0.4%) will rekindle its bid for AstraZeneca (AZN +3%) by late 2014. The British firm rejected its ₤71B offer in May. Pfizer walked away despite being within 7% of the price AstraZeneca wanted.
Under British takeover rules, the negotiations could restart as early as August 26 if AstraZeneca invites Pfizer back to the table. Pfizer cannot initiate discussions until November 26. The rules also allow Pfizer to make a single offer via private phone call to AstraZeneca but this option is rarely used because the process stops if the target says no.
It all depends on Ian Read's enthusiasm for a higher bid. This may be unlikely considering what happened in May.
