Macfarlanes posts £3.1 million profit per equity partner as City firm's focused model outperforms expansion-driven rivals, with AI investment cited as a key profitability driver alongside discipline on headcount

Macfarlanes, the 150-year-old City law firm, has posted a profit per equity partner (PEP) — the standard measure of law firm profitability, calculated by dividing total partnership profit by the number of equity partners — of £3.1 million, a figure that places it ahead of several Magic Circle firms on this metric and significantly above the Silver Circle average. The firm's strategy is explicitly non-expansionist: unlike Magic Circle rivals pursuing global office networks, Macfarlanes has maintained a focused, London-centric practice with selective international capability. The profitability result reflects the commercial logic of restraint — a smaller equity partner base sharing a high-quality revenue stream generates superior per-partner returns compared with larger networks carrying the overhead of global offices. The broader context highlighted in the commentary around these results is the role of AI investment as a profitability accelerator. The UK legal market saw a record £534 million of private equity capital flow into law firms in the past year, with AI positioned as the central investment thesis — the argument being that AI tools reduce the cost of routine legal work, improving margins without requiring proportionate fee increases. For a focused firm like Macfarlanes, AI adoption at the practice level potentially amplifies the already-favourable economics of its lean equity structure. The results will sharpen debate about whether the global expansion model pursued by , , and other Magic Circle firms delivers superior returns relative to the focused mid-size City model — a strategic question with direct implications for how firms structure their AI investment and technology adoption programmes.
