As leader of the firm’s Corporate Services practice group, Mark Stoneman is responsible for coordinating with the firm’s managing partner to strengthen the group’s planning, execution and operational practices. In his law practice, he facilitates the structuring, financing and completion of acquisitions, mergers, divestitures, joint ventures and partnerships. His background in accounting and finance helps him to ensure that the agreements related to these transactions are consistent with his client’s goals and expectations with respect to financial matters, which can be of critical importance in transactions of this nature.
For large, national and international, privately held businesses—often in the industrial, pharmaceutical or biotechnology industries—Mark brings a constructive and imaginative outlook to highly successful transactional combinations. He advises from front-end strategic planning to managing the deal process through favorable execution and closing. Mark’s acquisition experience extends to transactions where real estate is a primary or sole asset.
When counseling clients in the preparation and negotiation of agreements, Mark translates the goals of his clients into “plain English” documents, which can be both understood by the parties and respected by the courts. During the course of such efforts, he finds that he is frequently able to uncover and resolve potential conflicts before they progress to litigation. Not only does this help to avoid the prospect of costly disputes, but it can ensure that clients’ expectations with respect to the agreements will be met or exceeded.
Mark serves large, privately held companies and smaller startups as outsourced general counsel. He helps as an on-call resource with daily affairs or when things go awry.
Active in firm management, in addition to leading the Corporate Services practice group, Mark is a member of the firm’s Executive Committee and Pension Committee. He previously served on the firm’s Opinion and Compensation Committees, and was chair of the Pension and Hiring Committees.
Mark is a frequent author and speaker on transactional law matters with numerous presentations to business and legal groups.
