Stock was founded as Carolina Builders Corporation (CBC) in Raleigh, North Carolina, in 1922. Carolina Holdings, Inc., was formed in 1993 as the holding
company for CBC and its acquired properties, which soon generated over $1 billion in annual revenues and held the first coast-to-coast footprint in the
industry. The name was changed to Stock in 2003 to reflect this national presence. In May 2009, The Gores Group, LLC, a private equity firm focused on
acquiring controlling interests in mature and growing businesses purchased a majority ownership of Stock, which now benefits from the firm’s operating
experience and flexible capital. Because of Gores’ business and financial acumen, Stock is now a stronger, leaner, more focused and innovative corporation
with strategic locations throughout the United States.

Effective August 9, 2013, Stock now trades on the NASDAQ stock exchange under the ticker symbol “STCK”. Through its various operating subsidiaries,
Stock Building Supply operates 65 locations in 13 states. In addition to its core residential building materials business operating under the Stock name,
certain Stock subsidiaries also operate under the Coleman Floor, Smoot Lumber and Bison brands in selected markets. >/p>
