What this is
How the Tokyo parent’s profit moved with Pokémon GO spending, years to February 2017–2019: about ¥15–18bn of net profit per $1bn of GO gross each year.
How it’s built
- Divide each year’s parent net profit by estimated GO gross for that year (vendor figures, converted at ¥108–112).
- Predict the 2018 fall in pretax profit from GO alone: ¥7.5–10.6bn, against an actual fall of about ¥10.0–10.3bn.
What we assumed
- GO gross spending per year from app-data vendors.No official figure exists; vendor estimates differ, and the ratio moves with whichever is used.
- Exchange rates of ¥108–112 per dollar.Assumed annual rates for each year.
Sanity check
The main-series games also moved the same way (Sun/Moon, then smaller releases), so moving together alone does not prove GO caused it.
Where it comes from
Our calculation from other figures in the trainer’s notes:
- EstimateGO gross by TPC fiscal window and quarter, TPC year to February 2017-year to February 2019 (Mar-Feb)
- EstimateMain series launch year control and parent GO pretax, year to February 2013-year to February 2017 (parent)
Show the working
- Pretax drop predicted from GO, year to February 2018: 7,512 to 10,606
- Pretax drop actual, year to February 2018: 10,034 to 10,281
- pretax/gross and NI per $1bn of GO gross by window
- FY2/17: 15,921/1.10 = 14.5 to /0.95 = 16.8 ¥bn per $bn
- FY2/18: 8,827/0.60 = 14.7 to /0.50 = 17.7
- FY2/19: 13,389/0.84 = 15.9 to /0.74 = 18.1
