Bill R. Kolb

Co-Chair, Mergers & Acquisitions Practice Group

I help clients complete their most important business transactions.

Bill Kolb has over 25 years of broad experience helping clients achieve their business objectives, including assisting them to raise money, acquire companies, go public, be sold, enter into complex licensing arrangements, and address their day-to-day ongoing legal needs. Bill works closely with clients in the life sciences, healthcare, technology, professional services and manufacturing industries, among others.

Bill is co-chair of the firm’s Mergers & Acquisitions practice group and has worked on scores of M&A transactions over the years, representing buyers, sellers, individual stakeholders, special committees of boards of directors, and investment banks. His M&A work has included acquisitions of public and private companies, tender offers, go privates, de-SPAC transactions, reorganizations and recapitalizations, strategic alliances and joint ventures. Bill has assisted domestic clients to make cross-border acquisitions and has advised foreign companies making acquisitions in the United States.

Bill regularly advises public and private clients on capital raises. His work in this area ranges from assisting large public companies on registered equity and debt offerings to helping start-ups obtain seed financing. Bill has represented numerous high-growth and emerging companies to complete financings with angel investors, venture capital firms and later-stage private equity firms.

Bill also enjoys counseling clients on their day-to-day legal needs. This includes providing corporate governance advice, attending Board and committee meetings, assisting public company clients on SEC reporting, drafting executive compensation arrangements, and negotiating license agreements.
