Current View:

This content is provided by Calfee, Halter & Griswold LLP.


Calfee’s Corporate/M&A practice is one of the largest and most prolific in Ohio, handling a significant number of complex and sophisticated transactions for clients around the country and globally. We represent both privately-held and publicly-traded companies, private equity funds, private entrepreneurs, and family-owned businesses, among other types of clients.

Calfee boasts a robust Merger and Acquisitions, Divestitures and Sales practice led by an active private equity client base and a large roster of public and significant privately held corporate clients. These financial and strategic buyers, coupled with our deep investment banking representations and relationships, drive a thriving and diverse M&A practice at Calfee.

We guide clients through the process of structuring, negotiating, and completing acquisitions and divestitures of assets and stock, mergers, strategic alliances, and joint venture arrangements. After closing, we advise clients on post-transaction integration and indemnification matters and, in the case of acquisitions, we often function as outside “general counsel” to our clients on day-to-day matters.
