Security Service Federal Credit Union has purchased the 24-acre headquarters property previously occupied by NuStar Energy in San Antonio. The credit union intends to use the 319,000-square-foot facility to support its ongoing corporate growth.

Why it matters

The acquisition allows the credit union to significantly expand its San Antonio footprint as it seeks to accommodate long-term organizational development. This purchase follows a series of ownership changes involving Sunoco and Truist Financial Corp.
