Regional casino operator Penn National Gaming (PNG) more than tripled its net income in the second quarter of 2018 despite only a modest increase in revenue.

Figures released Thursday show PNG generated revenue of $827m in the three months ending June 30, a 3.8% gain on the same period last year. By contrast, adjusted earnings were up 8.6% to $247.1m and net income hit $54m from just $17.1m last year.

A few caveats: first, adjusted earnings fell to $131.2m (+15.6%) once you subtract the rent PNG pays its real estate investment trust landlord Gaming and Leisure Properties Inc. Second, PNG changed its definition of adjusted earnings in Q1 to “enhance comparability with our competitors’ definition” of the metric.

Those quibbles aside, PNG’s three main geographic categories were all in positive territory in Q2, with the Northeast region’s eight properties rising 4.4% to $423m, the South/West segment’s eight venues up 6.5% to $163.4m and the Midwest segment’s eight venues rising 1.6% to $230.5m.
