Partner - Assurance Services


Marc Siegel is a Partner in EY’s Financial Accounting Advisory Services. He advises clients on reimaging their corporate reporting away from compliance exercises and more as vehicles of communication. Fluent in both financial and ESG reporting, Marc helps clients develop a transparent articulation of the long-term value creation story throughout all the communication channels to investors, which is key to maximizing valuation opportunities. Marc’s expertise in corporate reporting has been built over 3 years, with deep experience in audit, buy-side research, policy, and consulting. In January 219, Marc was appointed as a board member of the Sustainability Accounting Standards Board (SASB).

Previously, Marc was a board member of the Financial Accounting Standards Board (FASB) with his second and final term ending June 218. During this time, the FASB finalized major new accounting standards for revenue recognition, lease accounting, financial instruments, hedge accounting, long-duration insurance, credit losses and many others. Further, Marc was instrumental in FASB projects on financial statement presentation, financial performance reporting, disclosure framework, and was involved globally with the International Accounting Standards Board (IASB), Enhanced Disclosures Task Force, International Integrated Reporting Council, and the Corporate Reporting Dialogue. At FASB, Marc hosted forums on both coasts with auditors, preparers, securities regulators, securities attorneys, investors, and audit committee members to kick off the Disclosure Framework project.

Prior to the appointment to FASB, Marc’s prior experience includes Director of Research at a boutique sell-side research firm providing detailed forensic financial statement analysis to mutual fund and hedge fund clients to support their investment decisions. He led a team of more than twenty analysts in the US and London doing forensic financial statement analysis designed to detect early warning signs of underappreciated business deterioration and to warn institutional investor clients about those risks. Also, Marc worked closely with Institutional Shareholder Services (ISS) corporate governance and ESG research teams to identify synergies in research processes and findings, especially around contentious shareholder voting situations.

Marc began his career at Arthur Andersen as both an auditor and as a litigation consultant.

Marc is a CPA licensed in New York. He has a Bachelor’s degree in Economics with a concentration in Accounting from the Wharton School of Business at the University of Pennsylvania.
