Dom Rizziolan highlighted Amazon's clear articulation of the return on investment for its AI infrastructure, noting that short-lifecycle assets break even in two to three years. He pointed to AWS's accelerating growth and margin expansion as evidence of strong ROI.
“So, so let's take, uh, Amazon first, because that was the clearest articulation by any of the hyperscalers on what the CapEx will translate to into revenue and cash flow at a net, you know, they, they broke out the different pieces of the CapEx, right?”
“and Jesse laid out on the short lifecycle piece, which is the piece that everyone would naturally worry about the most, that they break even in roughly two to three years, and then they last five to six years of useful life, right?”
“Um, and when you think about what that means, it means that even on the shortest lifecycle asset of this, the company should have very, very strong ROI C.”
“Um, and then when you think about what that means in the context of AWS growth accelerating to 37% at 50% incremental operating margins, you don't just have management saying ROI C's are going to be strong, you see that coming through in the acceleration of the revenue growth and the EBIT margin expansion as well.”
