GlaxoSmithKline plc GSK, one of the largest health care companies, reshaped its business following the Mar 2015 completion of the three-part, inter-conditional transaction with Novartis related to its Consumer Healthcare, Vaccines and Oncology businesses. This UK-based company now focuses on its three core businesses – Pharmaceuticals (respiratory, HIV), Vaccines (pediatric, adolescent, adult, and travel vaccines) and Consumer Healthcare (wellness, oral health, nutrition and skin health products).However, like many of its peers, Glaxo is facing challenges in the form of increasing competition, genericization and pricing pressure in major markets.In this scenario, investor focus remains on late-stage pipeline candidates and their commercial potential, restructuring and cost-cutting initiatives and performance of new products apart from the usual top-and bottom-line numbers.Glaxo’s performance has been pretty good with earnings surpassing expectations in three of the last four quarters. Overall, the company has delivered an average positive surprise of 4.34%.Currently, Glaxo has a Zacks Rank #3 (Hold), but that could definitely change following the company’s earnings report which was just released.
