Roth Capital analyst Jeff Martin maintained a Buy rating on OSI Systems and raised his price target to $97 from $89 following the company's Q2 results that beat estimates by a "material" margin. In a research note to investors, Martin says OSI has significantly strengthened its Security product portfolio over the past several years and is showing "attractive" organic growth despite headwinds from the Mexico contract. International markets appear robust, he says, adding that while the Mexico contract served as a headwind for 1H19, the underlying strength in Security and Optoelectronics is driving meaningful growth in revenue and profit.
