What Abernathy MacGregor does

Abernathy MacGregor operates as H/Advisors Abernathy, the U.S. arm of the global H/Advisors communications advisory network. Founded in 1984 and headquartered in New York, the firm advises CEOs, boards, and senior executives on stakeholder engagement, reputation management, and high-stakes communications scenarios. The U.S. entity maintains offices in New York, Los Angeles, San Francisco, and Houston, and is part of a broader network spanning 40+ offices across 20+ countries with 1,500+ professionals globally.

The firm delivers eleven distinct professional service offerings: Corporate Communications, Crisis & Reputation Management, Data/Digital/Creative Strategy, Hedge Funds, Investor Relations & Financial Communications, Litigation, M&A and Shareholder Activism, Private Equity, Public Affairs & Policy Advisory, Sustainability and ESG, and Transformation & Change. These are bespoke advisory engagements rather than software products or platforms; core delivery is senior-led counsel combined with research, content, and digital execution capabilities. The firm has no disclosed proprietary technology platform, API, or software product, though the Data/Digital/Creative offering references AI-driven digital strategies for reputation work.

Revenue is generated through professional services fees on quote-based, bespoke engagements. Pricing is not publicly disclosed. The go-to-market is enterprise field sales via direct senior advisor relationships with C-suite executives and boards. Primary client segments are corporations and boards, blue-chip hedge funds (with combined client AUM cited at $150B), and private equity firms and their portfolio companies. Recent strategic activity includes a CEO transition (Carina Davidson, June 2026), sustained Chambers and Partners recognition, and ongoing thought-leadership publishing including the annual M&A Leaks research report (Volume VI, 2026).
