Ann: 2019 Interim Results Presentation, page-15

Certainly a very good result with the lift in Operating NPAT of 159.8%. The Financial Report reveals an EPS (statutory) of 3.7c for the six months (based on Statutory NPAT of $11.972M). However, the Directors advise "Finance lease payments expected to stay flat moving forward" while "Future annual borrowing costs expected to be ~$45M". If we are to expect a more or less flat NPAT in the 2nd half then the annual EPS will be 7.4c. With todays price of 204c, that gives a PE of 27.5. which is pretty high if the company's profit is flattening out. Flat revenue need not mean flat NPAT but any increase in margin is well and truly baked into the PE of 27.5.
Clearly, the market got ahead of itself in valuing the company and is having to rerate its expectations.
