The Live Nation firm that operates Dublin's 3Arena doubled its profits in 2015.
Massive shows from the likes of U2, One Direction and Taylor Swift helped the Docklands music venue – one of the busiest in the world – to pre-tax profits of €6.19m.
The number of people attending 3Arena shows was up from 599,427 to 666,318 overall.
Bono and co's homecoming shows last November were the biggest draw of the year, bringing in €4.6m in box office receipts.
The four sold-out performances were witnessed by some 46,784 fans.
Apollo Leisure Group Ltd posted a 102% increase in pre-tax profits, up from £2.55m to £5.16m. The dramatic increase was chiefly due to the company's administrative expenses dropping from £8.56m to 6.1m.
In January, trade industry journal Pollstar named 3Arena as the 15th busiest concert venue in the world.
