Mergers & Acquisitions


We have the knowledge and experience to handle the most complex transactions.
Posternak’s mergers and acquisitions practice, a key component of the firm’s Business Practice Group, is comprised of knowledgeable and highly regarded corporate, tax and securities lawyers with extensive experience in corporate transactions of every nature.  The types of transactions in which we are involved range from modest asset and stock acquisitions and divestitures to multimillion dollar leveraged buy-outs, cross-border mergers, joint ventures, reorganizations, going private transactions and tender offers.

We take a practical approach to transactions, always seeking to help the client get the deal done on time and within budget.

Together with our colleagues in such specialty areas as environmental law, litigation, employee benefits, taxation and intellectual property, we guide clients through the myriad issues that may arise in a deal, however complex, including structuring and tax planning, securities and regulatory compliance, and negotiating and drafting.  We are results oriented, always striving to first fully understand and then achieve our clients’ business objectives, maximizing value and minimizing risk, while fostering and maintaining a positive, constructive relationship between the parties to the deal.

Privately-held businesses form the core of our M&A practice.
Our clientele ranges from publicly traded companies to emerging businesses, with middle-market, privately-held enterprises forming the core of our M&A practice.  Our clients include individual, corporate and private equity firms, buyers and sellers, boards of directors, joint venture partners, investors and lenders in a wide range of industries.

We counsel the principals of these entities, as well as their accountants and advisors, in order to help them appreciate not only the legal aspects of acquiring or selling a business but also the related issues of integrating business cultures, financing, and capital and ownership structures.  Our Business Practice Group colleagues can advise regarding business succession planning and individual financial, tax, retirement and estate planning.
