Mainstage Theatrical Supply Announces Strategic Recapitalization

Mainstage Theatrical Supply, LLC has secured strategic growth capital from a private equity consortium led by Sidereal Investments, LLC. Founded in 1981 by brothers Craig and Dean Sternke, Mainstage has grown from a local theatrical-supply company in Milwaukee into a national partner for the design, integration, and installation of lighting control systems, stage curtains, and rigging equipment. The company now operates regional offices in Houston, Memphis, Milwaukee, and Pensacola, supporting customers across the Midwest, Southeast, Southwest United States, and internationally.

In a statement, the company says, "This investment will support the next phase of Mainstage's long-term growth strategy while providing Craig Sternke with a structured pathway toward retirement. Dean Sternke will continue to lead the company as president, and Ken Bryant, of Sidereal Investments, will join the executive team as director of finance.

"In planning for my eventual retirement, our number one priority was to find a partner that shared our corporate values and vision for the business," says Craig Sternke. "After an extensive search, Sidereal proved to be just such a partner." Dean Sternke adds, "We believe this will be a transformative event for us, providing the opportunity to expand the Mainstage platform into new markets while remaining faithful to our commitment to industry-leading service levels that consistently exceed expectations."
