About Joseph Halloum

Joseph represents private equity sponsors and public and private companies in a wide range of significant transactions and investments, corporate governance issues and securities law matters. He routinely advises boards of directors, management teams, and sponsors and their investment professionals on M&A tactics, fiduciary duty matters, investment and regulatory compliance, investigations, activism, and media and PR matters.

Joseph is regularly called upon for his broad-based transactional experience in high-profile and complex M&A and private capital investments, including LBOs, strategic sales, carve-outs, tender offers, take-privates and exits, joint ventures, domestic and cross-border transactions, growth equity, PIPEs and toe-hold investments in public companies, IPOs and SPAC transactions, debt and equity financings, restructurings and recapitalizations, and SEC compliance matters.

He has also represented numerous companies and boards in connection with large shareholder matters and activist defense and unsolicited takeover situations, the majority of which remain confidential. Among publicly disclosed situations, he has advised TriNet Group with matters involving its largest shareholder Atairos Group, Del Frisco’s in its settlement with Engaged Capital, Yahoo! in its settlement with Third Point, Autodesk in its settlements with Sachem Head Capital and Eminence Capital, and Tessera Technologies in its settlement with Starboard Value.

Joseph was recently listed on the "M&A Powerlist" by Legal 500, named 2022 "Lawyers on the Fast Track" at the California Legal Awards, recognized with a 2019 California “Trailblazer” award by The Recorder, ranked from 2019-2023 as a Super Lawyers “Rising Star” for M&A and has been consistently named in IFLR1000. He was also recognized by The Daily Journal with a 2016 California Lawyer “Attorney of the Year” award for his work on the Broadcom-Avago merger.

Joseph is actively involved with his alma mater, UC Berkeley. In the Fall 2024 semester, he will be teaching Corporate M&A at Berkeley Law. He is the Founder and Co-Chair of the GC Executive Fellowship Program launched in partnership with Berkeley Law. The program brings together select Bay Area general counsel from leading technology and life sciences companies and private equity firms to network with their peers and discuss emerging business and legal issues.

Supplementing his active involvement advancing a variety of programs at Berkeley Law and the Berkeley Haas School of Business, Joseph founded and oversees the Emma and Joseph H. Halloum Business Competition and Negotiation Competition. The Business Competition is the first and only one in the nation to combine the disciplines of a university's law school and graduate business school in a negotiation case competition. The Negotiation Competition is an internal honors competition at Berkeley Law which aims to develop corporate law negotiation skills for first-year law students.
