King & Spalding posts double digit global growth as UK revenue surges

Reading time: two minutes

King & Spalding has reported double‑digit financial growth in 2025, driven by surging demand, expanded talent and standout performances across its international offices.

The Atlanta‑founded firm said global revenue rose 13% to $2.68 billion, marking its 17th consecutive year of growth. In the same vein, profits per equity partner climbed 22% to $7.26 million, while net income increased 11% to $1.303 billion. Revenue per lawyer also grew by 8.6% to $1.93 million.

King & Spalding’s chairman Robert Hays said higher demand resulted in an increase in hours worked, but added that no single matter drove the financial results; instead, teams “competed well to get more work” and delivered “world‑class service” for major clients, including Disney and Goldman Sachs.

Billing rate increases played a role, consistent with trends across the legal sector, but Hays noted that alternative fee arrangements were also contributors to revenue.

The UK office delivered one of the firm’s strongest performances, with revenue reaching $148.16 million, which is a 48% increase from last year. Hays attributed the surge to a standout disputes team and continued expansion in transactional practices. Recent lateral additions, including tax partner Russell Warren and a 12‑partner finance team from Cadwalader, also supported growth. The London office now approaches 100 lawyers.

Elsewhere, King & Spalding posted above‑average revenue increases in Paris and the Middle East, including in Riyadh and Abu Dhabi. In New York, the firm relocated its 250‑lawyer office to a new space on Avenue of the Americas.

Other strategic moves bolstered the firm’s global momentum, including a combination with Saudi law firm Al Fahad & Partners that made King & Spalding “one of the first international firms to launch under the new regulatory regime” in the region, as well as the launch of its first Australian office in Sydney.
