Revenues at WH Smith Ireland jumped 66% to €19.29m (£14.1m) in the year ending 31st August 2014 from €11.6m (£8.47m) for the same period the year before.
The Irish Independent has seen accounts filed with the Companies Registration Office in Ireland, which shows that despite the revenue rise, pre-tax profits fell slightly from €1.54m (£1.12m) to €1.5m (£1.1m).
The newspaper said the fall was due to the rise in administrative expenses and distribution costs.
WH Smith Ireland, which mainly operates stores in Dublin Airport, as well as at Shannon Airport and at Arnotts department store, increased its employee numbers from 55 to 74 last year.
The jump in revenues can be attributed to WH Smith winning a contract in 2013 to run shops in Dublin Airport’s Terminal One.
Sales of John Green’s The Fault in Our Stars (Penguin) was one of the company's bestselling titles in Ireland.
Nielsen BookScan figures for Ireland show that overall sales topped €106m in 2014.
