Revenue model is fee-based, with long-term client relationships generating recurring engagements.

护城河分析

Brand trust: EY's signature on financial statements is required for public companies globally. Regulatory moat: audit market dominated by Big Four due to regulatory requirements and liability considerations. Talent pipeline: recruits from top universities worldwide, creating a self-reinforcing talent network.
