K3 Advisory Group has been ranked the UK’s No.1 mid-market M&A adviser in the latest London Stock Exchange Group (LSEG) Global M&A Mid-Market Financial Advisory league tables.
The H1 2026 results place the Group:
• No.1 in the UK
• No.2 in Europe, with only two deals separating it from first place
• No.4 globally
K3 holds a clear lead in the UK, having completed almost four times as many qualifying transactions as its nearest competitor during the period. For clients, however, the significance of that activity extends beyond deal volume.
That breadth of market exposure gives advisers current insight into buyer and investor appetite, valuation expectations and how transactions are being structured. For shareholders, investors and management teams, this can help shape the right strategy, sharpen the positioning of an opportunity and keep a process moving when challenges arise.
What this means for K3 Deal Advisory clients
The rankings follow the recent launch of K3 Deal Advisory, formed by bringing together established corporate finance and capital advisory teams from across the Group.
Its advisers support entrepreneurs, investors and corporates on sales, acquisitions, investment and funding strategies. Clients work directly with senior dealmakers and can draw on wider specialist expertise from across K3 Advisory Group where required.
The league tables provide an independent measure of the Group’s position in the market. More importantly for clients, they reflect the experience, relationships and current market insight available to support each mandate.
After nine consecutive years at the top of the UK rankings, K3 is on course for a tenth. The Group also sits just two deals behind first place in Europe and ranks fourth globally.
K3 Deal Advisory’s focus remains straightforward: understand each client’s objectives, provide clear commercial advice and run a disciplined process aligned with the outcome they want to achieve.
