The Globe and Mail reports in its Friday edition that Starbucks has explored a takeover of Chipotle Mexican Grill, in a move that would reunite chief executive officer Brian Niccol with the burrito chain he led before joining the coffee chain two years ago. A Reuters dispatch to The Globe says the potential deal comes as restaurants wrestle with uncertain demand from inflation-weary consumers and rising operating costs, prompting companies to look for new avenues of growth while facing pressure to improve profitability. Starbucks has worked with advisers in recent months on a takeover proposal for Chipotle. Shares of Chipotle increased by 6 per cent Thursday, while Starbucks shares declined 3 per cent. Analysts said any acquisition would likely be a costly undertaking for Starbucks, which is still investing heavily in its turnaround efforts. "A deal could require heavy borrowing or issuing shares," said Lale Akoner, a strategist at eToro. "Without a compelling financial case, investors may view the deal as an expensive distraction." Starbucks is in the midst of a turnaround under Mr. Niccol, who has prioritized customer satisfaction through investments in staffing and store improvements aimed at reducing wait times.
