King & Spalding increased its London revenues by almost 50% during 2025, as global revenue and profit per equity partner also rose by double digits.
The US firm’s London office, which is led by disputes partner Tom Sprange KC (pictured), posted a 48% increase in City revenues to reach $148.2m – one year after passing the $100m mark for the first time.
Commenting on the results, Sprange KC said: ‘2025 proved to be a breakthrough year for the London office, reaping the benefits of a selection of strategic investments. We moved to our new offices in 8 Bishopsgate in May 2024 and have been expanding with top talent across our transactional, disputes and regulatory teams, at both senior and junior levels.’
‘This expansion, coupled with an emphasis on organic growth through promotions and our extensive trainee programme, laid the foundation for a stellar year,’ he added.
Since opening in London in 2003, the office has grown to 49 partners and 99 fee earners in total.
2025 saw a number of significant hires in London, including transactional tax specialist Russell Warren, who joined from Travers Smith, where he led the tax practice, and financial services litigation partner Jonathan Swil, who joined from A&O Shearman.
Those hires came on the back of a major team hire in 2024 which saw a 12-partner finance and restructuring group join from Cadwalader, led by London fund finance head Samantha Hutchinson.
The London hike comes as global revenue also climbed to $2.68bn, a 13% increase on 2024’s $2.37bn.
PEP growth was even steeper, climbing by 22% to $7.26m, a figure which puts the firm among the top 10 most profitable Am Law 100 firms.
Equity partner count dipped by 9% to 179, while its non-equity partner count rose by 11.1% to 360.
In total, the firm added 39 partners in 2025 across 12 offices worldwide. Major moves included the launch of a new office in Sydney led by Darren Gardner, the head of the firm’s global human capital and compliance team.
