Target turns to PepsiCo’s Brian Cornell to restore its fortunes E-mail Tweet Facebook Google Plus Linkedin Share icons by Geoffrey Smith" itemprop="author" class="article-byline-author"> Geoffrey Smith @FortuneMagazine 6:37 AM EDT Target Corp TGT is tapping Brian Cornell of PepsiCo Inc. PEP as its new chief executive, the Wall Street Journal reported Thursday. Cornell, 55, will replace Gregg Steinhafel, who quit three months ago after a series of problems at the retailer, culminating in a disastrous breach of data security around Thanksgiving last year which wrecked its holiday season sales. Chief financial officer John Mulligan has been acting CEO since then. The management problem has overshadowed Target’s stock all year. The company’s shares have fallen 3.3% while the S&P 500 has gained 7.4%. Cornell has had two spells at PepsiCo and is currently head of its Americas Foods business, but also spent three years at Wal-Mart Stores Inc. (fortune-stock symbol=”WMT”], where he was head of the Sam’s Club chain of warehouses. The WSJ reported that Cornell faces some daunting challenges in the new job, such as deciding whether or not to pursue a so-far unsuccessful expansion into Canada, beefing up its e-commerce performance and generally streamlining a decision-making process that had gotten too slow and cumbersome under Steinhafel. An open question is whether the appointment of the former Wal-Mart man signals a change in Target’s approach to its product ranges and the presentation of its stores.
