Nightclub operator Luminar has felt only "marginal impact" on its sales following the introduction of the smoking ban in England in July.
Britain's largest branded late night operator saw turnover rise 3.5% to £99.3m for the six months ending 30 August.
Pre-tax profits grew by 22.6% to £26.6m.
With a third of its trading during this period falling under the smoking ban in England the group said there had been only a marginal impact on sales in its branded operations, while its unbranded and leased operations had seen weakness and Luminar would look to resolve this with the introduction of smoking terraces in the venues.
Chief executive Stephen Thomas said: "We are delighted we are progressing strongly to achieving our strategy of 120 nightclubs, 80 of which will be branded. We will therefore continue to invest in our business and deliver excellent performance."
