Calfee’s team of more than 25 dedicated mergers and acquisitions attorneys provide practical legal guidance to clients to assist them in navigating through a purchase, sale or other business transaction.

With a strong foothold in the regional middle market, we represent both privately held and publicly traded companies, private equity funds, family owned businesses, and private entrepreneurs, among other types of clients.

Calfee handles transactions of all sizes – with completed transactions ranging in value from $500,000 to more than $3 billion. We know how to staff transactions and use resources in a cost-effective manner and how to add value with our competitive rates. Whether a deal involves a relatively straightforward asset purchase of a single facility business, or a multi-entity, multi-jurisdictional transaction for a publicly held conglomerate, we have the necessary experience to get it done.

We understand that each transaction is unique. We have the resources to staff each deal with appropriate attorneys from other practice groups who have experience in areas such as Securities and Capital Markets, Tax, Commercial Business, Intellectual Property, Labor and Employment, Real Estate, Environmental and Antitrust, to name just a few. Collaboration with these team members ensures that each transaction is efficiently managed, while adequately covering the myriad issues raised by any transaction.

Our M&A attorneys focus on understanding the business motivations underlying each transaction. We help our clients identify the best transaction structure, devise strategies to mitigate risk and overcome obstacles, and negotiate reasonable protections in light of the size and complexity of the deal.

Clients' Work



Partnering With Clients

Our M&A attorneys guide clients through the process of structuring, documenting, negotiating and closing acquisitions and sales of assets and stock, mergers, strategic alliances, and joint ventures. After closing, we advise clients on post-transaction integration matters. In the case of acquisitions, after a closing we often function as outside “general counsel” to the acquired business on day-to-day legal matters. 

Meeting Clients' Business Objectives

We work with our clients to negotiate a reasonable allocation between the transaction parties of liabilities and risks. We help our clients to make practical decisions that further their business goals.

We also counsel our clients on potential tax savings or deferral opportunities in structuring transactions.

Dedication to Client Service

Calfee’s M&A professionals are committed to delivering superior client service and partnering with our clients. We live by these five “golden rules” of client service:

  • Know the client and never lose sight of the client's objectives. 
  • Be creative in identifying solutions that enhance the client's success.
  • Be responsive and communicate with the client regularly.
  • Give proactive, practical advice to enable the client to make informed business decisions. 
  • Trust and respect the client in order to foster a strong, long-term relationship. 

Many of our M&A attorneys have previously served as in-house counsel, corporate board members, or advisory board members for companies. This collective experience has shaped our M&A attorneys’ perspective and provided valuable insight into the mindset of our clients.

Collaborative Teamwork

Our M&A attorneys approach engagements with a sense of teamwork – working together internally across multiple disciplines and working closely with our clients’ management and other internal and external advisors – to efficiently coordinate transactions and achieve optimal outcomes. Whether guidance is needed in environmental, employment, intellectual property, real estate, employee benefits, data security, tax planning and compliance, or any other legal area, we bring to the table the necessary expertise.
