Ann: PWR Reports Strong Revenue and Profit Growth, page-2

The company are being somewhat modest here with their reporting.
Reported figures are:
Sales Up 22%
EBITDA Up 17%


But taking out Jobkeeper in 1H21, the real changes in the key metrics are:
Sales Up 22%
EBITDA Up 39%

So despite all the challenges from elevated lead times for supply chain, a lack of chips delaying OEM work and higher input prices including wage rates - margins still expanded significantly. It seems this can be put down to management deciding to prioritise the higher margin work given the constraints, and probably also reflects the business' pricing power.

What I love most is that the first metric in the Performance Overview is 'Shares On Issue" which has barely changed since the company listed. If only more managers knew the importance of this metric to long term shareholder returns!
