Pfizer Inc. (PFE), the world’s largest drugmaker, said it will incorporate its Indian subsidiary’s animal health unit into its larger animal division, signaling the company has progressed in its push to divest the business. The action is a step toward worldwide consolidation of New York-based Pfizer’s animal health operations under one roof, the company said. The change was announced in a statement today by the Bombay Stock Exchange. Pfizer is shedding its animal health and nutrition businesses this year as part of Chief Executive Officer Ian Read’s plan to focus on developing new drugs. The reorganization will let potential buyers or investors assess the business unit as a whole, said Scott Rostan, chief executive office of Training the Street, a New York company that trains finance professionals, and a former M&A banker.
