Columbia Engineering Acquired by Undisclosed Buyer
Your Growth is More than a Transaction.
Committed to Your Goals
Buying a firm to meet growth goals can be complicated. It can also be tremendously rewarding. SN’s M&A advisors believe that the most often overlooked areas during the M&A process (people and culture) are actually the biggest success factors.
Our lead with people approach is woven into all of our buyer services including target sourcing, valuation, deal structure, term sheet/LOI, due diligence, and cultural assessment.
Your Vision for the Future
The decision to sell your firm can be described as deeply personal, exciting, complex, and overwhelming. That’s why we built a team of Merger & Acquisition advisors who fully understand every part of the process – because they’ve been on the front lines of both buying and selling a firm.
With our unique lead with people approach, we’ll guide you through firm valuation, buyer identification, deal structure and negotiation, and closing assistance.
