The last financial year saw deal conversions increase by 60% compared to the previous year, representing a significant increase in both completed transactions and total deal value.
Deals included the cross-border sale of a majority stake in Redhead Int to DB Schenker Logistics, the world' second largest logistics and transportation provider, and the sale of the Pole Position Indoor Karting business to Teamsport, Europe's largest indoor karting operator.
Richard Rankin, head of corporate finance and partner at Armstrong Watson said: "I'm delighted to see such a dramatic increase in activity for our corporate finance team, and closing on our best year ever is a fantastic achievement.
"Our pipeline is looking incredibly strong for this year with a number of deals already completed in Q1 despite the BREXIT uncertainty we are looking to build on the success of last year."
The growth follows Armstrong Watson's move to its new Leeds office in the centre of the city's business district back in 2014.
