How do I guide companies through their most important transactions, and beyond?

Every acquisition, sale or significant corporate matter begins with an understanding of what uniquely defines that company, what the owners are trying to accomplish, and what risks threaten to impede that outcome. That perspective doesn’t end at closing; it often becomes the foundation for my helping clients navigate whatever comes next. I enjoy M&A and other transactional work because it allows me to build lasting relationships with the people behind the businesses.

Bringing 25+ years of experience and insight to M&A and business transactions

Companies regularly turn to James Larimore to facilitate their business sales, acquisitions, divestitures, joint ventures, related financing transactions and other commercial dealings. His experience representing both buyers and sellers gives him a broader perspective on how deals are structured and negotiated, helps him identify trends in the current market, and enhances his ability to get deals done.

Experience that extends across industries and beyond borders

James’ clients hail from a broad range of industries, including healthcare, grocery, construction, manufacturing, and energy (including exploration, production and oilfield services). He works regularly with private equity funds pursuing acquisitions in diverse markets. His practice also extends beyond Oklahoma; he has led transactions involving businesses across the country and served as U.S. counsel for several Canadian companies with operations in the United States.

Client service that continues long after the closing

For many of James’ clients, the closing of a transaction is only the beginning of the relationship. Because he puts in the time to really learn a business during the deal phase, clients often continue to involve him in the legal issues that arise as the company grows. This ongoing work frequently includes corporate governance matters, commercial agreements, ownership and organizational issues, capital raising activities and other business transactions that build on the knowledge gained during the original engagement.

Remaining personally involved throughout the transaction

Clients who hire James get James, continuing to work directly with him throughout the life of the matter. Rather than dividing major portions of a deal among numerous attorneys, he remains the primary point of contact, coordinating specialized advice when needed but always maintaining responsibility for the overall strategy and execution. In his view, this creates essential continuity, improves efficiency and ensures that someone is always focused on how each piece of the transaction affects the deal as a whole.
