Pinned straw:
I finally got clarity and there was nuance but not what I expected. It is a good lesson in how to considered info like this at face value and thinking about the issues/risks in it and the need to clarify. It also makes me look a little silly although I did warn "subject to clarification".
The variation amount of $149.8m includes revenue from the signage variation from 2023 and inflation from the initial 3 years which total to of ~$8m.
Adjusting for this, the years 4+5 have a value of ~$62.7m instead of $72.8m for an average of $27.1m. Re-cutting the calc from an inflation accrual basis and FY25 and FY26 annualised revenue more likely lands between $27-29m.
As such, the uplift is more modest, inline with Redflex which was ~11% and has a lesser impact on my valuations. My model has been adjusted to now better reflect inflation and through this I noticed an error (silly again!) that used a flat growth rate in FY26 rather than the new contract/variation aggregation I track.
Asu such 2.0, below are the re-cut valuations which still incrementally lift on the prior prior update. I note the FY26 figure has barely changed but if I fix the calculation error and leave in my bad take on the NSW contract, it would be $1.85/sh so it a downgrade on like for like basis.
