Our people take ownership of their work and pride in doing it right, and that has changed how our customers and partners view us. I look forward to bringing that same culture to Bastion.”
— Chris Maltese, CEO
SHELBY TOWNSHIP, MI, UNITED STATES, November 11, 2026 /EINPresswire.com/ -- Bastion Infrastructure Group, LLC (“Bastion”), formerly DiPonio Holdings, LLC, announced its formal launch. The new name marks the company’s transition from a holding entity into an operating platform that drives value, structure and strategic direction across all
its current and future businesses. Bastion is backed by Evolution Strategy Partners (“Evolution”), an Austin-based independent sponsor partnering with essential businesses in the lower middle market.Bastion’s platform began in 2022, when Evolution partnered with DiPonio Contracting. Headquartered in Shelby Township, Michigan, DiPonio is a full-service underground utility contractor that has served municipal, county and state agencies across Michigan for more than three decades, self-performing water main, sanitary and storm sewer, lead service replacement, box culvert and road base work. After achieving exceptional organic growth, the company expanded through its acquisition of Lodestar Construction, a second-generation Grand Rapids contractor whose wet and dry utility capabilities, including electrical conduit, sewer and water main construction and road building, extended the platform’s reach across West Michigan.
Bastion takes its name from the strongest point of a fortification, the place that holds when pressure mounts. That is the role Bastion will play for its family of businesses. Each of its entities will keep their brand, culture, field leadership and customer relationships that earned their reputation, while Bastion stands behind them with operational guidance, coordination and institutional knowledge, along with capital strength, bonding capacity, shared back-office systems and long-term strategic planning. Guided by three principles - Preserve, Coordinate and Advance - Bastion is positioned to expand its footprint and capabilities by acquiring additional infrastructure businesses across the Great Lakes region.
In conjunction with the launch of its new name, operating platform and strategic positioning, Bastion also announced two leadership promotions. Chris Maltese, President of DiPonio Contracting, has been named Chief Executive Officer of Bastion Infrastructure Group, and Kevin Koss, Vice President of Finance of DiPonio Contracting, has been named Chief Financial Officer.
“I am proud to have led DiPonio Contracting to double-digit growth over the last two years, and I am just as proud of the culture our team has evolved along the way,” said Chris Maltese, CEO of Bastion Infrastructure Group. “Our people take ownership of their work and pride in doing it right, and that has changed how our customers and partners view us. I look forward to bringing that same culture to Bastion as I lead and champion the company into its next generation of growth and expansion. There are great opportunities on the horizon, and my team and Evolution are well positioned to make this a success.”
“Launching Bastion is an important step in building greater market value and cohesive strength across our infrastructure portfolio,” said Stenning Schueppert, Managing Partner of Evolution Strategy Partners. “Bastion gives its businesses a stronger foundation and a clear identity as we pursue new partnerships across the Great Lakes region. I have the utmost trust in Chris and his senior leadership team and their ability to lead and grow this company, and I am excited about what we will build together.”
