Yes. Thanks, Ruplu. So a few components there. So when we think about the mix between Korea versus Arizona, obviously, for Korea, we're ramping today. That's obviously very important for us to continue to accelerate that ramp. There's a lot going on there. I mean, to add a little bit of color because we talked about the expansions in these locations as well. So in Korea, obviously, as we migrate the SiP from the Korea facility over to Vietnam, that opens up space in the Korea facility and that we're quickly filling with assets that we already have on order to continue that ramp profile, I would say, short term. Then when we get to midterm, we have the new building on the Songdo campus that will be opening at the end of this year that will start to ramp to continue that acceleration. And then that announcement is also contemplating these K4 or that's our Gwangju location, where we have 2 new buildings where we recently broke ground, and those will drive the acceleration into late '27 into '28. Those buildings will be completed for construction in late '27. To give you an idea of scale there from a spend perspective, the construction in Korea will basically for 2027 be in the $400 million to $450 million range. And then we talked about, obviously, this expansion in Vietnam, where the SiP is going in. And that expansion facility-wise for 2027 is in the $50 million range. Obviously, for Arizona, that ramp is later. Again, the facility will be completed late this year. We'll start moving assets in. So for that customer, that will be more of a 2020 -- late 2028 type ramp profile. And then when we think about gross margins for both facilities, what we -- obviously, when we think about Arizona, we do expect the overall cost to be higher related to building depreciation, labor. We're managing that through multiple ways. Number one is keeping the factory very heavily utilized. So it will be lower product mix, higher utilization. And the customers we have planned for that facility understand that we want to reduce the seasonality, preferentially load in Arizona and then obviously offload into Asia. So that allows us to really keep that factory running at a high level. And obviously, it will be our most advanced related to automation. So that will help us from a labor perspective. So long term, while there may be some slight deltas in the margin profile, we wouldn't expect a big delta between the 2. So I think that's a positive outlook. When we think about risk, the CAP agreements really help us from a risk profile. There's obviously multiple terms in those agreements that build confidence for us in getting that profile built. The asset fungibility, we think about any high-density fan-out program, 2.5D, even wafer bumping type things, these assets are fungible up and down that stack. Obviously, the scale that we're working with this customer is hard to offset. But I'd say, regardless, the technology is very fungible to different customers.
