About Big Four News

Big Four News is an independent weekly newsletter dedicated to providing clear, timely, and insightful coverage of the world’s largest professional services firms: PwC, Deloitte, EY, and KPMG.

Every week (and more frequently when major stories break), I deliver concise briefings on the most important issues shaping the Big Four — from major litigation and regulatory matters to AI transformations, talent strategies, partnership model changes, global network challenges, and reputational risks.

My goal is to give you a clear, cohesive big-picture view of the entire Big Four ecosystem.

What You’ll Get

• Independent analysis — free from corporate spin or internal bias

• Curated global coverage across audit, consulting, tax, deals, risk, and technology

• Strategic context and real-world implications

• Clean, scannable format designed for busy professionals
