Tower Semiconductor Deep Dive

Tower Semiconductor’s low-loss photonics chips halve lasers in 1.6T optical modules, supporting a $680 million annualized photonics run rate and customer wafer prepayments through 2027.

$SIVE and $AAOI, yes for a 2027 timeframe. That's the nuance. Sivers you're coming on with 100M CW DFB laser capacity + 2 external foundries (maybe 300M in total), and all my supply chains mapping maps to larger hyperscaler suppliers. AAOI you're coming on with $471m transceiver revenue + 400K ELS units for 2028 timeframe. With hyperscalers + demand eating up all their capacity. There's just a $600m ATM which presents overhang near term. $NBIS already got re-rated but it's very positive upcoming for Q4 2026 (esp. with price hikes). Legacy memory like $ESMT + (some I haven't named yet) + regular memory names like Samsung, I do think will strongly outperform near term. And obviously CPUs names like $INTC $AMD $ARM as of recent.

I'm not having a fun day since I got sick today. But the bottlenecks are having a good time: $AMD +9.13% | $INTC +14.16% | $ARM +14.33% CPUs go brrr $SIVE +10.32% | $AAOI +3.39% | AMS OSRAM +24.61% Lasers go brrr $EWY +4.08% | $DRAM +2.83% | $MU +2.23% Memory go brrr $NBIS +4.7% | $CRWV +5.03% | $IREN +1.73% Compute go brrr Probably most material developments were CPU:GPU ratio expectations + CPU demand (from new AI releases). As well as optical developments from ECOC 2026 (as seen with $MRVL PR + others) Still a lot to catch up on.

Copart $CPRT just acquired $ACVA for $1.9B. The filings came out on the 17th, and I've spent 12 hours a day analyzing everything since. I read so much my eye drops stopped cutting it, had to switch back to vitamin A for the dry eyes. As usual, the reality is way more complicated than anything I've seen on social media so far. I break it all down, and what it means for my Copart thesis. Have fun. (Link in bio/below.)

The main duo $SKHY and Samsung are having a fun day. I'm still long memory (eg. $EWY / $DRAM ) since if capacity agreements extend 3-5 years... and your analysts model 2.8-3.3x 2027E. Risk/reward is attractive over time. But I think legacy memory a very interesting trade currently due to ASP hike potential.. It also just so happens these same companies procure memory from even smaller memory companies (that might have higher sensitivity)... So if you want to, you can track $PSMC wafer allocations, and find some interesting companies that likely replace $MU discontinued legacy memory through Alliance or supply directly to Samsung. Won't mention them on X, but just throwing out some research ideas.
