Jefferies analyst Sheila Kahyaoglu says that while there has been investor pressure to breakup United Technologies, she sees a "more efficient path to create value." The analyst derives $1.8BB in higher earnings from volume/mix/productivity improvements over the next three years, which she believes should translate into $20B in value. United Technologies has lagged peers on earnings growth and margin expansion, but the company is "at a turning point," Kahyaoglu tells investors in a research note titled "Thesis Update: The Key to Share Price Outperformance is Not a Break-Up." She expects margin improvement to drive earnings momentum and keeps a Buy rating on United Technologies with a $157 price target.
