The merger would reshape the competitive landscape by forming a conglomerate which spans commercial aviation and defence procurement. United Technologies provides primarily commercial plane makers with electronics, communications and other equipment, whereas Raytheon mainly supplies the U.S. government with military aircraft and missile equipment. United Technologies and Raytheon shares have dropped 7% and 4.5% respectively since their deal was announced, as investors expressed disappointment with the low value of synergies the companies announced. Investors also fret that major clients of the companies such as the Pentagon would seek to review their supply chains.
