Hannah, why don't you just, I know that you dug into this in such detail and I don't want to speak ahead of your expertise to Matt's question.

The methodology, how we actually got into it.

And a lot of it was based on numbers that we could find in the past historically, and then trying to predict what would happen in the rest of 2025.

So for example, the sales and marketing, we had some data that 2024 was 1 billion in sales and marketing.

And then in H1 of 2025, that was 2 billion, for example.

So we can build a picture using constraints in this way.

And from that, you can try and understand the costs of the company as a whole.

If you think that the software part is rapidly depreciating, you might want to get in on this part of building and serving infrastructure at a scale.
