Investors are selling $BESI, in our view, because customers increasingly prefer or consider shorter HBM stacks, since HBM is expensive. Our industry information points to customers requesting stacks of four or six memory dies. Fewer layers mean fewer connections and, where hybrid bonding is used, fewer bonding steps per stack, and shorter stacks fit package-height limits more easily with conventional solder. That could delay equipment adoption and weaken the nearer-term HBM opportunity for $BESI, which supplies hybrid-bonding equipment. Logic folding is the tailwind. It places parts of a circuit above one another on vertically connected layers joined through hybrid bonding, so signals travel shorter distances and the chip runs faster on less energy. Those benefits hold even when an inference system needs less HBM, and the layers still need aligning and connecting with exceptional precision. In our view, that can create more hybrid-bonding demand than this delay takes away. Wider folding also pushes inspection and measurement into more logic-chip applications. We expect that to lift spending faster than chip volumes for $ONTO and $CAMT, and for $NVMI, whose materials and chemistry checks address problems that get harder as circuits move into vertically connected layers. Longer term, folding could make chips on established processes more capable for $UMC. That is our prospective thesis, not an announced UMC program. Deeper dive available at Convequity.

Boost Run $BRUN said on October 26 that it has closed "more than $600 million in non-dilutive project financing" so far in 2026. In my October 19 update, I said the stock depends less on demand than on whether $BRUN can finance the next ~$1B of GPUs without selling shares at beaten-down prices. The release also says: → $BRUN has established "a fully funded runway to accelerate customer deployments through the fourth quarter of 2026," with additional financing "proceeding as planned." → $BRUN delivered the first phase of a multi-phase project to "a leading AI research and product company," which matches its $471.7M May 2026 contract with Thinking Machines Lab (Mira Murati's AI startup). → Several more projects are "nearing hand-off in the coming weeks." → Founder and CEO Andrew Karos: "Customer payments exceed our debt payments every month." The $600M+ is YTD, and lessors funded $268.3M of new GPU leases in H1 2026 alone. So if those leases count toward the $600M+, $BRUN has closed more than $331.7M since June 30, about half to almost two-thirds of the $527-686M of new leases I estimated its H2 2026 build needs. The release doesn't say what the financing costs or how much of it closed since June 30. However, the Q3 10-Q, expected in mid-November, should disclose how much $BRUN leased in Q3 and at what rate. If the 10-Q confirms the $600M+, I'd drop the $62.2M stock sale from my bear case, and the question shifts from whether $BRUN can fund its build to what the new debt costs.
