About Dennehy Robert

Robert Dennehy is a seasoned MACOM Technology Solutions Holdings, Inc. executive who currently serves as Chief Operating Officer, a role to which he was promoted in November 2025. His career at MACOM reflects a long, steady progression through operational and leadership positions, making him one of the company’s most experienced internal leaders. Before becoming COO, he served as Senior Vice President, Operations beginning in October 2013, and earlier as Vice President, Operations from March 2011. He also led MACOM’s Cork, Ireland subsidiary as Managing Director from 2006 through March 2011. Dennehy’s background at MACOM goes back even further. He joined the company in 1993 as a test engineer and later took on product management and other roles of increasing responsibility. That long tenure gave him broad exposure to the company’s product lines, manufacturing environment, and global operating model. It also positioned him to develop practical expertise in factory operations, supply chain coordination, cross-functional execution, and scaling an international semiconductor business. In leadership terms, his profile is strongly operational. MACOM’s recent announcement described his new COO responsibilities as continuing oversight of the company’s global operations, manufacturing, supply chain, and operational strategy. His promotion suggests a mandate to help strengthen execution across the business as MACOM continues to grow and serve a diversified customer base. Because his career path has been built largely inside the company, he brings institutional knowledge, continuity, and familiarity with MACOM’s long-term priorities. Biographically, MACOM states that Dennehy holds an Associate’s degree in Electronic Engineering and a Diploma in Business Administration from Henley Business School, London. That combination of technical training and business education aligns well with his career trajectory in semiconductors and operations. Overall, his professional record is best characterized by deep internal experience, steady advancement, and a focus on operational performance rather than external-profile public board leadership.
