And the global half is already moving. $ELMT bought 4.99% of Masan High-Tech Materials for $124.75M on Oct 1, and expects the Vietnamese supplier to stay its key refiner even after Springer comes online. The ~$100M Refining & Trading bucket covers Australia and Spain on top of that. https://t.co/lTme3cYw9M

@Million_Sancet Works out to ~$105M a year, and it runs five years vs the ~3-year take-or-pay term on most of the backlog. That narrows the gap against their 7-year colocation rent. Tho with go-live in early Q2 2027, none of it counts toward $BRUN's $400M ARR exit for 2026.

@ValueInvestShow $DECK is a heavy buyer of its own stock too. It repurchased $338M in Q1 alone, and the board added $3.5B in May, leaving $4.7B authorized as of June 30. Tho there's also ~$120M of old IEEPA tariffs it started filing to claw back that isn't in the guide yet.

The optical engine accounts for over 50% of an optical transceiver's cost, and it contains the most demanding alignment work in the module. For years, engines were built by active alignment: a technician switched on the laser and nudged parts into position until the light coupled. That was workable at 10G, 25G and 100G. At 400G and 800G the tolerances became too tight for manual assembly, and demand driven by AI exceeded what human throughput could supply. $POET's Optical Interposer replaces active alignment with passive assembly. It is a silicon wafer with waveguides and mechanical guides etched into it. Lasers, detectors and electronics are placed on it by automated pick-and-place machines, with nothing powered up during assembly. The parts align passively at the wafer level, much as Lego bricks fit together by their shape. The effect shows up at the transceiver maker. The engine arrives pre-aligned on a standardised substrate, so the remaining assembly looks like conventional electronics manufacturing. Foxconn does that kind of work at high volume, and it was historically locked out of optical transceivers because building them required deep photonic expertise around the engine. Our note's reading is that the interposer takes on the optical complexity so assemblers such as Foxconn, Luxshare, and LITEON do not have to, which helps relieve one of the bottlenecks in optical connectivity for AI clusters.

ProQR Therapeutics $PRQR CEO Daniel de Boer bought $513K across two separate purchases on July 7 and July 9, and a company director bought another $229.5K in late June (real money for a Dutch CEO). PRQR is a small-cap RNA-editing biotech backed by a major pharma partner: Eli Lilly. Their collaboration, running since 2021 and expanded in 2022, could pay ProQR up to $3.75 billion in milestones plus royalties, real validation for a company this size. The balance sheet just got stronger too: ProQR raised roughly $59 million in late June 2026, with Lilly buying in alongside the public offering to keep its stake intact, a vote of confidence from the partner who knows their science best.
