Market Position
Top-tier boutique financial and strategic PR firm with strong positioning in M&A communications and activist defense
Overview
Abernathy MacGregor (ABMac) is one of the most prominent strategic communications and financial public relations firms in the United States. Founded in 1991, the firm specializes in advising corporations, boards, and executives on high-stakes communications challenges including mergers and acquisitions, activist defense, restructurings, IPOs, and crisis communications. The firm has built a strong reputation for handling complex, sensitive situations that require sophisticated messaging to financial audiences, media, and other stakeholders. ABMac serves a blue-chip client base that includes Fortune 500 companies, major financial institutions, and private equity firms. The firm is particularly well-regarded for its M&A communications practice, where it advises both acquirers and targets on transaction-related messaging. Its deep relationships with financial journalists, institutional investors, and proxy advisors give it a distinctive edge in capital markets communications. Abernathy MacGregor operates as a subsidiary within the Havas Creative Network, part of the broader Vivendi-owned Havas Group. Despite its integration into a global communications conglomerate, ABMac maintains its boutique identity and specialized focus on strategic and financial communications. It competes primarily with other financial PR specialists such as Joele Frank, Kekst CNC, and Sard Verbinnen & Co., and is consistently ranked among the top advisors in M&A communications league tables.
