McGrigors has posted half-year results that reveal a 25 per cent growth in fee income compared with the same period last year.
The results coincide with an increase in merger-related market rumours surrounding the Scottish-headquartered firm.
Turnover at McGrigors grew to £29.6m for the first six months, a figure that, if matched in the second half of its year, would take the firm's total revenue to around £60m.
The firm's managing partner Colin Gray said the six-monthly figures showed the continued growth McGrigors was enjoying from a strong business pipeline.
"The 25 per cent year-on-year growth reflects the high quality of the work that we’re undertaking for a number of large clients," added Gray.
In the last six months McGrigors has advised on a succession of major projects, including a £122m waste water PPP deal in Northern Ireland, the $550m (£274.71m) acquisition of Talisman Energy's North Sea assets and the €945m (£642m) Austrian roads PPP.
Despite the strong results, McGrigors has been linked recently to a number of firms, including Eversheds. Both firms have denied that they are in merger talks.
Along with its half-year results, McGrigors has also announced its latest crop of new partners. Glasgow-based real estate specialist Alan Cook and London-based tax lawyer Rupert Shiers have both entered the partnership.
