Macquarie analyst Bob Summers said GNC Holdings' Q4 and near-term results will prove challenging but management has made decisions that will significantly increase the company's long-term potential to succeed by simplifying pricing and having consistent in-store and online pricing. The analyst said these efforts will pressure margins, but shares are pricing in "draconian" outcomes with shares trading at just over 4x P/E. Summers expects free cash flow to remain positive, which could be further enhanced by cutting the dividend and notes there are no near-term debt maturities to create credit risk. The analyst said even a "slight bend" in same-store sales trends could produce a dramatic positive outcome and reiterates his Outperform rating and $20 price target on GNC Holdings.
