US professional services firm Sikich has acquired Jefferson Wells, a Milwaukee-based provider of risk and compliance, finance and accounting, and tax services, from staffing giant ManpowerGroup in a transaction valued at $100m (€92.4m), with around $89m (€82.2m) in net cash proceeds at closing after adjustments.

International Accounting Bulletin reported that Jefferson Wells has been active in the US market for more than three decades, working with clients across multiple sectors including public and regulated companies, and reported US revenue of $76m (€70.2m) in 2025.

The transaction, which closed on 30 April, brings more than 300 Jefferson Wells employees into Sikich and is expected to strengthen the firm's presence in healthcare, life sciences, and manufacturing and distribution.

Sikich chairman and CEO Christopher Geier said: "This acquisition enhances existing capabilities across our business, including deep expertise in risk and compliance, finance and accounting, and tax, making Jefferson Wells an ideal fit as we continue to scale. Both teams share a conviction of a people first culture and the belief that clients deserve practical, actionable solutions delivered at the highest level of quality."

ManpowerGroup North America region president Ger Doyle said the deal creates exciting opportunities for the business and its people, and that the two firms have strong alignment in capabilities, culture, and growth ambition. He said ManpowerGroup is now energised to focus on its core business and continue delivering value for clients and candidates across North America.

The acquisition reflects sustained consolidation activity within the US professional services and accountancy sector, as firms seek scale to address growing client demand for integrated risk, compliance, and financial advisory capabilities.
