Simmons posts double-digit growth, targets 'AI-enabled' future

Simmons & Simmons has recorded a strong set of financial results, with double-digit growth across revenue, profit and profit per equity partner.

Revenue hit £690 million in FY25/26, an increase of 12% on last year, and profit per equity partner rose 11% to £1.25 million.

The firm also increased profit by 14% to £245 million. In FY24/25, growth was more modest, with revenue up 7%, PEP rising 5% and profit increasing 6%.

The results come as the firm closes its 10-person Cambridge office, which became part of the firm in 2019 when it acquired legal engineering company Wavelength.

Simmons said the consultancy's legal engineering capabilities had since been fully integrated into the firm's global business. It said no jobs had been lost as a result of the relocation.

Behind the numbers

Global managing partner Emily Monastiriotis credited the firm’s AI strategy, expanding international platform and highly specialised sector focus for the performance.

The firm also invested in partners throughout the period - 37 lateral partners arrived across 14 offices, and nine were promoted to partner.

Simmons is organised around five sectors: asset management and investment funds (AMIF), financial institutions, healthcare and life sciences, TMT, and energy, infrastructure and construction.

The firm said those sectors accounted for 93% of total firm revenue, with AMIF and TMT seeing particularly strong revenue growth at 12% and 13% respectively.

“The results also reflect a year of major investment – in our partnership, new offices, and our AI capabilities,” Monastiriotis said.

“Our newly launched five-year business plan sets out a clear ambition to become a leading AI‑enabled law firm and to strengthen our position as strategic advisers in our five chosen sectors.”

Simmons recently signed up with Legora, and uses AI tools Percy and Copilot alongside a “suite of autonomous agents” such as the firm’s NDA agent it developed in partnership with Berlin-based legal tech Flank.
