SMX CEO Peter LaMontagne accepts 2026 Wash100 Award.

SMX CEO Peter LaMontagne accepts 2026 Wash100 Award. SMX CEO Peter LaMontagne has accepted the 2026 Wash100 Award, recognizing his leadership in driving strategic growth through acquisitions, partnerships and expanded mission capabilities across the government contracting market. Jim Garrettson, CEO of Executive Mosaic and founder of the Wash100 Award, presented the honor to LaMontagne during a recent meeting. Why did Peter LaMontagne win the 2026 Wash100 Award? LaMontagne earned his second consecutive Wash100 Award for leading SMX through a period of accelerated growth driven by acquisitions, strategic partnerships and contract wins. A key milestone was SMX's acquisition of cBEYONData in February 2025, which expanded the company's capabilities in enterprise resource planning, financial analytics and budget management, while adding new platforms and services to its portfolio. The company also advanced its artificial intelligence initiatives through partnerships with C3 AI, Google Public Sector, World Wide Technology and ColorTokens, strengthening its capabilities in AI, digital engineering and zero trust cybersecurity to support mission-critical operations. SMX's momentum is further reflected in a $532.1 million U.S. Navy contract, secured through a joint venture with Perrygo Consulting Group, to provide IT infrastructure and enterprise support for naval aviation operations. "I'm delighted to award Peter his second Wash100 Award," said Garrettson. "His role on boards like MANTECH gives him a broader view of the market, which helps guide his leadership. He brings to SMX an increased aperture of the market's opportunity and his vision for his people." Garettson also highlighted LaMontagne's success in GovCon, citing his strong track record in strategy, operational execution and growth across executive leadership roles. "Peter has grown SMX into a formidable player in GovCon and I'm excited to see what he has in store for 2026," the Executive Mosaic CEO added. Who is Peter LaMontagne? LaMontagne has served as CEO of SMX since June 2020, leading the company's strategy and growth while overseeing teams delivering digital transformation solutions. He brings experience in cloud, data analytics and cybersecurity, along with a track record of guiding high-growth technology firms through investment lifecycles and more than 20 mergers and acquisitions. Prior to SMX, he was CEO of Quantum Spatial, Novetta and Paradigm Solutions and a growth adviser at M33 Growth. Earlier in his career, he served as a U.S. foreign service officer in Beijing. What is the Wash100 Award? Since 2014, the Wash100 Award has recognized the most influential leaders shaping the government contracting landscape. Recipients are selected based on their leadership, strategic direction, impact on the federal market and potential to drive industry trends in the year ahead. Executive Mosaic congratulates Peter LaMontagne and the entire SMX team on this Wash100 achievement. Share the Post:
