DAX- Subtract specified rows in Summarize Table

[Anonymous]

I generate the table using summarize, and now what i want to do that is, the guy do in the below image. I found that on community page.

Now i wanted to subtract the values in pg1 (red highlighted) specifically, and the master logic behnd is that to get the difference of Loreal 2020 company value - loreal 2019 company value, and shows that value in 2019 year row. and then Loreal 2019 company value - loreal 2018 company value and and shows that value in 2019 year row and so on. But cant do that, if some one helps it will be a great.
