In a sign that the Lexington, Massachusetts-based firm expects to acquire its initial portfolio investments, Tagg Romney’s private equity firm Solamere Capital LLC enlisted the operational expertise of the former chief executive of Wal-Mart.

H. Lee Scott, Jr., who was CEO of the discount department stores retailer from January 2000 to January 2009, will join Solamere as an operating partner and as a member of the investment committee. The private equity firm was founded last year by the son of former Massachusetts governor Mitt Romney. In addition to Tagg Romney, the firm was co-founded by managing partners Eric Scheuermann and Spencer Zwick.

Scott joins John Miller as an operating partner at Solamere. In addition to Miller's position at the PE firm, he is also CEO of Kansas City, Missouri-based food company National Beef Packing Company. It is unclear whether the firm, which also operates as a multi-family office, will invest the private assets of the Scott family.

In a statement, the firm said Scott’s “leadership experience and his ability to identify growth opportunities will greatly benefit our investors, partner funds and future portfolio companies by adding substantial value to our investment process.”

Calls placed to Solamere were not returned by press time.
