Lubar & Company

Lubar & Company

Lubar & Company is the single-family office formed in 1977 by Sheldon Lubar after the profitable sale of Sorgel Electric. Based in Milwaukee, the firm manages the Lubar family's permanent capital. Today, Sheldon's son David J. Lubar leads the firm as President and CEO, continuing a multi-generational mandate centered on long-term partnership rather than fund-life exits. The firm deploys proprietary capital via a buy-and-build approach across a concentrated middle-market portfolio spanning industrial manufacturing, healthcare facilities, food processing, mobility, and energy services. Its portfolio companies range from ChemDesign Products, a specialty chemical manufacturer in Marinette, Wisconsin, to Drilltec, a Houston-based provider of protective products for the oil country tubular goods market, and American Pasteurization Co., a Milwaukee high-pressure food processor. Lubar & Company also owns Lake Express, the first high-speed ferry in the United States connecting Milwaukee and Muskegon, Michigan — an operating asset that reflects its willingness to hold transportation infrastructure for decades. Lubar & Company operates with lean permanent capital; specific AUM is undisclosed. David Lubar is a long-time member of YPO and has chaired the Greater Milwaukee Committee, embedding the office within the regional business network that generates proprietary middle-market deal flow. The firm's most visible adjacent asset is the Milwaukee Brewers Major League Baseball franchise, where David Lubar serves on the Board of Directors. May 2022: David Lubar joined the Milwaukee Brewers ownership group as a principal investor, formalizing a decades-long relationship with the franchise (per Milwaukee Brewers, 2022). The firm's structural differentiator is its indefinite hold period — Lubar & Company does not invest with an exit strategy. That architecture, combined with an operating philosophy it calls Professional Ownership®, means portfolio companies can pursue multi-decade growth plans without pressure to sell or recapitalize on a private equity timeline. Succession is embedded: the Lubar family's second generation now runs day-to-day investment decisions, while the family foundation, Lubar Family Foundation Inc., operates alongside the investment office.
