“We are excited to welcome Martin’s Super Markets to the SpartanNash family,” says David Staples, SpartanNash Company’s president and CEO. “Martin’s has been a valued independent retail customer since 2005, and we have the greatest respect for the Martin’s management team and its commitment to their associates, customers, and the communities they serve. We look forward to working with members of the team to continue to deliver the quality shopping experience and high level of customer service to Martin’s customers. Our long-standing relationship has built the foundation for our future success and will enable us to grow our corporate retail business in Indiana and Michigan consistent with our long-term strategic growth strategy. We also believe this investment in our corporate retail business will help us take full advantage of our opportunities to generate value for all SpartanNash stakeholders.”

The transaction is expected to close early in the first quarter of the fiscal year ending December 28.
