The combination expands Pinion's services in land development and project consulting, bringing A1's regional expertise in coordinating complex projects into a larger national firm. For Sioux Falls, it means a local development consultancy is now part of a broader agriculture advisory network.

A1 Development Solutions, founded in 2017, has worked with clients across South Dakota and the Upper Midwest for nearly a decade. Pinion traces its roots to 1932, but the transaction's value was not disclosed.
