After hosting investor meetings with management, Oppenheimer analyst Rick Schafer says he remains a buyer of Monolithic Power even with the stock up greater than five times over the past five years. Investors are still underestimating the company's growth acceleration potential, which could ultimately drive a $1B top-line over the next three-to-five years, Schafer tells investors in a research note. He views high-end notebook, server, game console and auto as Monolithic's "four pillars of growth." Each vertical represents $100M incremental revenue potential over the next three years, the analyst contends. He keeps an Outperform rating on the shares.
