Just noticed something interesting about Taiwan Semiconductor that's worth thinking about. The stock's already up 61% in the past year, but honestly, I think there's still real meat on the bone here.

First thing that caught my attention: their AI exposure is massive right now. They're fabricating chips for basically every major player in the space - Nvidia, Apple, you name it. High-performance computing now accounts for 58% of their revenue. But here's what I actually like about their model - they're not just riding the AI wave and hoping it doesn't crash. They've got this diversified manufacturing business that serves smartphones, gaming, all kinds of tech. So even if AI hype cools down, they've got other legs to stand on. That's solid business architecture.

The profitability story is what really grabbed me though. Their gross margins hit 62.3% in Q4 2025, up from 59% the year before. Operating margins at 54%, up from 49%. These aren't just good numbers - they're getting better. And they're planning to increase capex this year to meet demand, which management says has historically led to strong growth cycles. It's the kind of reinvestment you want to see.

Then there's the valuation angle. Revenue jumped 26% year-over-year, earnings per share up 35%. That's real growth. And the stock is trading at just 18 times forward earnings. For a company with this profitability profile and growth trajectory, that feels like a reasonable entry point. Not cheap, but fair.

What makes their manufacturing business for sale proposition interesting is that they're not locked into any single trend. They adapt to whatever the next wave is. That's a rare quality in tech. Worth keeping on the radar if you're looking at semiconductor exposure.
