The SAP slides only give sales numbers, not the number of customers wanting to move
SAP sales would always be large due to the price of the product compared to Gentrack.
It would be good to get the amount of contracts in the slide but each contract would be different since each purchase of modules will vary from customer to customer
Therefore we can only guess.
From Gartner, the number of customers on SAP ECC (on premise) and still to commit to the 2027 date is about 23000 as of Dec 2023.
So if SAP cloud intake is about 30% p.a. then 6900 customers are planning to roll to SAP Rise this year
Although this is big and dramatically cuts the addressable market for companies like Gentrack, I don't think it's a cause for panic. There will always be a percentage that will wait it out, likely from SAP ISU customers.
On SAP ISU, there could at least 800 customers (as of 2017) but that is probably bigger now according to other unverified sources (up to 1500 as the highest case).
I also have not included Oracle customers so number of customers still not on cloud could be 2000+.
Finally I haven't accounted for the economics of Gentrack deployments which are charged on #billable meter points per year on top of one off contract revenue.
Surprisingly no one has gone through the Gentrack pricing in previous straws. Then again, there's not much info on it except what is in the MS research note, so no need for concern. This will need to be discussed in another post.
Having mentioned all the above, I believe Regal and WAM did not sell because of valuation.
They may have sold to get cash for other opportunities
