NEW YORK, NY — September 11, 2025 — Prosek Partners, a global integrated marketing and communications firm for financial and professional services, today announced that Eric Bonach has joined as a Managing Director in New York in the firm’s special situations practice. Eric joins Prosek from H/Advisors Abernathy, where he spent the last seven years, most recently as a Managing Director helping to lead the M&A and activism team.

Eric brings over twenty years of experience providing communications counsel to clients involved in transformative and high-stakes situations, including mergers and acquisitions, shareholder activism, proxy contests, unsolicited takeovers and “bet-the-company” litigation. In addition, he has deep expertise in financial communications and reputation management, working closely with clients to proactively enhance their public visibility and media relations programs.

Jennifer Prosek, Founder and Managing Partner of Prosek Partners, said: “Eric’s track record advising clients through some of the most complex and high-pressure moments in their corporate lives makes him an invaluable addition to our team.

He previously held roles at Burson-Marsteller on its financial communications team and began his career at Joele Frank where he spent eight years.

Eric’s hire underscores Prosek’s continued investment in its growing special situations practice and builds on the firm’s commitment to providing best-in-class counsel to clients across complex corporate, financial and regulatory environments.
