About

ESG Credibility From
the Shareholder Side of the Table

Most ESG advisors arrive from consulting. Anthony Riha arrives from the institutional-shareholder side — the side that scrutinises, votes, and decides. Eighteen years running corporate M&A, shareholder engagement, activist-defence and sustainability mandates across Asia-Pacific, from inside the firms that set the assurance standard.

Anthony Riha is Mahat Advisory's ESG & Sustainability Sectoral Partner — the credibility layer that allows Mahat's service partners to deliver into ESG-, sustainability- and shareholder-sensitive environments. He brings eighteen years of Asia-Pacific executive leadership across corporate M&A, complex AGMs and EGMs, activism campaigns, and sustainability — consistently from the perspective of institutional shareholders, including Scope 3 supply-chain reporting.

His authority is institutional, not asserted. He leads Global Enterprise Solutions at UL Solutions — the global leader in independent assurance and certification for the Scope 3 supply-chain demands of institutional shareholders and regulators, accredited by CDP at Gold level — and serves as Senior Vice President for M&A and Sustainability Solutions and Principal at OpenEngagement. Earlier, he was Vice President for Asia at ISS Corporate Solutions and Senior Vice President at Alliance Advisors, working with boards, C-suites and sustainability teams across the region.
