Larger AI chip packages are pushing manufacturers toward glass substrates. We regard LPKF Laser & Electronics ($LPKFF) as one of very few suppliers that can make the tiny, closely spaced holes through the glass reliably and in volume. 1. The silicon chips and the organic (resin-based) substrate beneath them expand by different amounts as the package heats and cools. A larger package makes that mismatch harder to manage, raising the risk of warping and damaged connections. Glass expands more like silicon. 2. $NVDA is requiring its Taiwanese and Korean suppliers to deliver glass substrates by 2028. 3. China's BOE is reportedly meeting with Samsung on a glass substrate partnership. 4. Producing these holes in volume is difficult. The holes, called through-glass vias, must be made without cracking the glass and then filled with copper. Our view is that LPKF's process, a laser pulse followed by a chemical etch, is built for that hole-making step. We are watching for its customers to move from development into production.

Ahead of 5 Nov, we are watching whether $IREN’s project delivery is reducing cash burn and whether further expansion has suitable funding in place. Longer debt maturities give IREN more time to complete projects and collect cash, reducing the urgency of returning to lenders during an unfavorable market. Its Microsoft GPU financing is closely matched to the associated contract and sits in a separate vehicle with limited recourse to the parent. We want that time used to establish operating cash generation that can support future investment and eventual debt repayment. At depressed valuations, our view is that IREN could provide a partial hedge against slower AI progress. If slower demand growth leads the largest cloud buyers to moderate construction, IREN could gain better access to GPUs and power for projects already sold. Earlier completion would start revenue sooner, and fewer new commitments would reduce the cash absorbed by construction, bringing positive free cash flow forward. This depends on existing contracts remaining sound. A collapse in customer demand or credit quality would, of course, hurt IREN.
