A&O Shearman’s $3.7B Revenue Triumph: First Post-Merger Results Revealed
Overview: A&O Shearman, formed by the 2024 merger of London-based Allen & Overy and New York-based Shearman & Sterling, reported a record-breaking $3.7 billion (£2.9 billion) in client revenue for its first fiscal year ending April 30, 2025. This milestone, exceeding pre-merger expectations of $3.5 billion, underscores the firm’s successful integration and robust financial performance, positioning it as a global legal powerhouse. Below is a detailed analysis of the results, key highlights, and implications, addressing the prompt and leveraging provided sources.
Financial Performance Highlights
- Revenue: A&O Shearman posted £2.9 billion ($3.7 billion) in client revenue, surpassing the $3.5 billion projected by Allen & Overy and Shearman & Sterling before their May 2024 merger. This positions the firm as the fourth-largest in the 2024 Global 200 rankings, ahead of Baker McKenzie but behind DLA Piper.
- Pre-Tax Profit: The firm recorded £1.1 billion ($1.4 billion) in pre-tax profit, reflecting strong financial health and effective cost management post-merger.
- Profit Per Equity Partner (PEP): PEP reached £2 million ($2.6 million), higher than either predecessor firm’s individual figures in the prior year but slightly below Allen & Overy’s standalone 2024 PEP of £2.2 million, due to one-time gains from a strategic partnership.
- No Regional Breakdown: The firm did not disclose revenue by region, limiting insights into market-specific performance.
Key Achievements
- Major Transactions: A&O Shearman advised on high-profile deals, including:
- Liberty Global’s $3.2 billion Sunrise Communications spin-off and dual listing.
- Prosus’ €4.1 billion acquisition of Just Eat Takeaway.com, securing EU antitrust approval.
- Shimao Group Holdings’ ~$11.5 billion offshore debt restructuring (advising lenders).
- TD Bank’s $14.6 billion exit from Charles Schwab (advising underwriters).
- XpFibre’s €5.8 billion debt refinancing and SAP’s $12.5 billion Qualtrics sale litigation.
- Pro Bono Commitment: The firm delivered nearly 120,000 hours of pro bono legal services, a 23% increase in average hours per lawyer, and donated over $2.7 million to charity, including Women for Women International.
- Global Scale: With 4,000 lawyers across 29 countries, A&O Shearman has created a seamless global partnership, enhancing client service across markets.
Challenges and Context

- Staff Departures: Nine London attorneys, including eight associates, left for Latham & Watkins in June 2025, following two structured finance partners. A&O Shearman also delayed associate start dates to January 2026, reflecting cautious hiring amid integration.
- Industry Comparison: The firm outperformed competitors like Clifford Chance (£2.4 billion) and Linklaters (£2.32 billion) by ~£500 million, distancing itself from traditional Magic Circle rivals.
