Applied Materials' larger stake in BE Semiconductor points to long-term hybrid-bonding potential despite delayed adoption in HBM. Applied agreed to raise its BESI holding from 9% to about 20%; HBM adoption timelines may not reflect the prospects for the technology as a whole. x.com  x.com 

BESI should see a huge hybrid bonding order wave, especially from HBM4E and HBM5 roadmaps, and its price is compelling after the July selloff. x.com 

Logic folding could create more hybrid-bonding demand for BE Semiconductor than shorter HBM stacks take away. Customers are requesting four- or six-die stacks because HBM is expensive; fewer layers need fewer bonding steps and fit packages more easily with conventional solder, weakening the near-term HBM opportunity. Vertically stacked logic still needs exceptional alignment as it shortens signal paths and cuts energy use. x.com 

BE Semiconductor Industries is a good long on its supply-chain importance, as recent Lam Research and Applied Materials news validates how important hybrid bonding is to advanced packaging. Upside looks more limited, though; it is unlikely to rise 300% like names such as Applied Optoelectronics. x.com 

BE Semiconductor Industries makes hybrid bonding equipment, a critical technology for 3D stacking of HBM4 memory and AI chiplets. It is a top 1% stock globally by combined business and share-price growth, showing European semiconductors are not just ASML. Revenue is forecast to grow 46% this year, with gross margins above 63%, well above peers. ASML patterns the wafers while BESI assembles and packages the finished chips, and being much smaller gives BESI more room for percentage growth. x.com 

BE Semiconductor Industries is the global leader in hybrid bonding equipment and a buy. At its 2026 investor day, per @QQ_Timmy, it raised long-term targets to €1.7-2.2B of revenue and a 45-55% operating margin, from €1.5-1.9B and 40-55%. The CEO said market conditions and orders have improved markedly since Q2 2025 on demand for 2.5D AI data center and photonics applications and new hybrid bonding uses in logic, memory and co-packaged optics. x.com 

Tower Semiconductor's stronger-than-expected capacity expansion lets it fill more optical-chip orders itself, reducing customers' incentive to move to foundries they regard as technologically weaker. Its hybrid bonding packs dense connections between photonic chips and their driver electronics, an advantage viewed as effectively unmatched among Western suppliers. Tower remains one of the highest-conviction holdings despite the portfolio trim. x.com 

ASML's long case may gain some pricing power as Intel, Samsung, TSM and the memory boom broaden demand beyond its former customer concentration. But it has bungled packaging, where throughput matters more than critical dimension for viable economics; charging a new-machine price for wider field of view complicates the opportunity. x.com  x.com  x.com  x.com  x.com 

Samsung has the most upside among the three memory makers because it holds memory, foundry and packaging under one roof, letting it shorten development cycles and give customers more options. Its HBM4 collaboration on AMD's MI455X with 432GB of HBM4, plus foundry talks, shows a major AI customer taking it seriously again. Expect strong DRAM, NAND and HBM4 contributions. @JonahLupton notes it trades at 4.4x NTM EPS, and HBM prices rising at least 100% in 2027 may not be in estimates. x.com 

SK hynix's buyback signals that management believes memory has become less cyclical, which the market doesn't yet price at 4x forward earnings. It announced a $29B buyback and cancellation and changed its policy to return at least 50% of free cash flow, from up to 50%. With long-term contracts, AI as a commodity with constant demand, and demand from AI devices and humanoids, memory should stay in high demand for years, and bottom-cycle multiples should be much higher than in the past. x.com
