Notable Representations, Key Contacts

Strategic Business Partners in Global M&A

At Weil, we partner with our clients and make it a priority to understand and appreciate their corporate organization and business strategy. We understand that any M&A transaction is part of this overarching strategy and can be the most significant business event in the history of an organization and in the lives of its executives. Our clients include the largest and most sophisticated public and private companies, boards of directors and special committees as parties on any side, and in any context, of the deal. Our decades of experience across industries and throughout geographies allow us to guide our clients through these transformative, and often complex, corporate events.
Our pragmatic, business-focused approach allows us to get the deal done. We offer clients solutions rather than simply pinpoint and analyze legal issues. Our record of success in volume, scope and size of deals speaks to the value we bring to a range of clients throughout the world daily.

Thinking Outside the Box

Clients come to Weil for M&A advice when the stakes are high and the typical game plan won’t do. Weil M&A lawyers know the playbook but also have the creativity, confidence and experience to know when to rewrite it. Our M&A team has done and seen it all – whether it’s navigating the turnover of a board mid-transaction; helping to bridge the valuation gap between buyer and seller; helping to turn a hostile deal into a friendly transaction; assessing and proactively addressing the complex regulatory schemes across jurisdictions; crafting a sophisticated cross-border joint venture structure to get a deal done in an inhospitable regime or jurisdiction; or juggling multiple contingent transactions for the same client simultaneously.

Boards of Directors, Special Board Committees and Governance

We represent Boards of Directors and Special Board Committees of companies ranging from the Fortune 100 companies to mid and smaller cap companies, including representations involving complex M&A transactions, takeover defense, actual or potential conflicts of interest, accounting issues, Sarbanes-Oxley compliance and other matters.

We have substantial experience assisting Boards of Directors and Special Board Committees with internal investigations, governmental investigations and litigation (including securities, class action and derivative litigations arising out of M&A transactions involving affiliated entities).

Nuanced Understanding of Activism and Takeover Defense

Weil has vast experience advising on sensitive matters involving hostile M&A, takeover defense, issues of shareholder activism and other efforts for corporate control. We take a multidisciplinary approach – which involves cross-disciplinary team efforts among our M&A, Public Company Advisory Group and Securities Litigation lawyers – and work successfully and proactively in situations involving all manner of active shareholders. We do not engage adversarially with active shareholders but rather seek to understand their objectives and help our clients work to achieve resolution that is successful to all parties.
