William Blair upgraded AptarGroup to Outperform from Market Perform. The company’s Q1 earnings beat estimates, driven by strength in proprietary delivery systems, injectables returning to growth, and the beginning of a recovery in North American consumer markets, the analyst tells investors in a research note. The firm believes AptarGroup’s actions to make its Beauty and Closures segments more efficient while investing in the higher-growth and higher-margin Pharma segment are yielding a “faster-growing and more profitable business with better visibility and steadier earnings-characteristics not yet reflected in the stock.”
