Amkor Technology Inc Goldman Sachs Communacopia + Technology Conference 2026

Yeah, sure. We are very excited about our announcement last night. Stepping back, at our Investor Day, we really outlined our priorities around strategic partnerships, technology leadership, and our geographic footprint. We have made meaningful progress, as you mentioned, Jim, with our recent announcements with both NVIDIA and TSMC, and then last night announcing that we are further expanding our footprint here in the U.S. What is driving that is really the demand for advanced packaging continues to strengthen. Our customers are collaborating with us very closely, and they are looking for longer-term arrangements in order to secure their supply. We have fully committed our phase 1, and with these recent announcements and ongoing conversations with other partners and customers, it is really given us the confidence that now is the right time to advance and expand further for phase 2.

Doug, why don't you share a little bit about the space that we have planned for phase 2?

Yeah, it's worth highlighting the scale of the expansion. When we first announced that we were going to build in Arizona in the U.S., we targeted phase 1 to be 33,000 sq m of clean room manufacturing space. The customer demand and really need for that in the U.S. has been very nice to see. Because of that, with our customers, we've moved forward with phase 2, which is actually our phase 2 is going to be larger than we originally planning. We're moving forward with 60,000 sq m of clean room space in phase 2. That was about double what we originally were planning based on initial customer discussions. When you look at the Arizona campus for phase 1 and phase 2, that'll be 93,000 sq m of manufacturing space.

If you were to do square footage, that's about 850,000 sq ft of clean room space. It's an incredible scale. On our campus, that's about 6, 7 miles from TSMC's campus that they're building in Peoria. We have 170 acres with phase 1 and phase 2. We still actually have room to build a phase 3 on that same area in the future when we continue to work with our customers. It's important to understand what's really driving this. Obviously, supply generally in the market for advanced packaging, demand is much higher than supply, so that's certainly driving it. But what we've seen is customers really wanting to be in the U.S. They want advanced packaging. Packaging is really the enabler of the semiconductor market at this point.

It's where you take the memory and the silicon and make it into the advanced packaging for your advanced compute. It's really something we're seeing from our customers, both current customers and discussions we're having. The need is there, and because of that, we are investing much more than we were expecting, but we still believe that for us, the risk is low based on what we're seeing in the market.

Yeah. We are still in the process of working through specific products, volumes, product lines. I would look at it as scaling similarly to what we have disclosed for phase 1. As a reminder for phase 1, we have currently shared that that could be about $1 billion in revenue, greater than 30% margin. I think for now, scaling that pro rata would be appropriate.

Sure. Yeah, the strategic priorities are really what is centered around Amkor's growth. I would say what we just talked about, the geographic diversification, that is really a differentiator for Amkor in what is driving our growth in Arizona. Stepping back on the strategic partnerships, I would say historically, advanced packaging was planned very late in the process. Today, with how advanced packaging is becoming more complex and an enabler for systems, that is where these partnerships are becoming deeper, longer term, more strategic. You are seeing that in our announcements, in the multi-year strategic announcements, and that is what is bringing more visibility into not only our portfolio, but our roadmap. That pillar is really critical to our growth. The technology is really essential for everything to happen, especially with AI.

We are developing systems with our partners in order to enable things that are going to support compute, and that is our fastest growing market. It is centered around the complexity of the architectures needed. I would say we are not just developing technology, but we are developing platforms, around 2.5D, high-density fan-out. We have many engagements today in 2.5D. We also have engagements in high-density fan-out, development around bridge technology, as well as co-packaged optics. Those three pillars are what we see are going to drive Amkor's growth, optimize our utilization, expand our profitability, and ultimately bring shareholder value.
