Ernst & Young

Ernst & Young, commonly known as EY, is a professional services firm that provides a range of advisory, assurance, tax and transaction services to clients across various sectors. Its assurance practice includes financial statement audits and related attestation engagements for public and private organizations. The tax division offers compliance, planning and advisory services covering domestic and international tax matters. Advisory services encompass consulting on strategy, operations, technology, risk management and transformation initiatives. EY also delivers specialized services such as forensic accounting, valuation and sustainability consulting. These offerings are delivered to corporations, government entities, nonprofit organizations and high‑net‑worth individuals.

The firm’s headquarters is located in the United States of America, and it operates through a network of member firms that serve clients in many countries around the world. As one of the largest global professional services networks, EY is frequently grouped with the other Big Four accounting firms due to its scale and breadth of practice. Its distinguishing attributes include a strong emphasis on audit quality, deep industry‑specific knowledge and a commitment to helping clients navigate complex regulatory environments. EY’s role as an auditor for numerous publicly traded companies places it within a regulated framework overseen by securities authorities in various jurisdictions. Structurally, the organization is organized as a partnership, with ownership held by its partners rather than being publicly traded. This partnership model influences its governance, profit distribution and long‑term strategic decision‑making.
