UMC approves an additional $3.2 billion as capacity tightens $UMC’s Q3 utilization reached 92%, with several 12-inch fabs fully loaded. Growing advanced packaging and silicon photonics demand is prompting the company to repurpose existing capacity. The additional budget supports expansion in Singapore and Tainan, while 2026 capex guidance remains $2 billion. This is bullish for UMC’s medium-term growth and semiconductor equipment demand. Capacity reallocation shows new applications are competing for manufacturing resources today; expansion creates potential equipment demand beyond the current spending cycle. $AMAT $LRCX $KLAC

UMC's now a second foundry source for deep trench caps (first was TSMC CoWoS), aimed at the interposer, substrate and package underside. So basically everywhere you could put one in the power delivery path.

UMC, Taiwan’s 2nd biggest chip foundry, has raised its capex to US$2 billion from $1.5 billion as it expands production in Singapore and Tainan, south Taiwan, media report. UMC will expand cleanroom capacity of its Phase 4 facility in Singapore and build a new fab in Tainan. Construction of the new fab is expected to take 20-months. UMC also said it plans to spend at least $5 billion over 3-years, including the $2B this year. $UMC $AMAT $ASML $LRCX $KLAC #semiconductors#

UMC, Taiwan’s 2nd biggest chip foundry, is looking to expand a fab in south Taiwan due to an overflow of advanced packaging and specialty AI-related orders (silicon interposers, DTC) from Qualcomm, Intel and SanDisk, media report, noting new plans for UMC’s Fab 12A P7 near Tainan, Taiwan, are under evaluation. Orders for power management chips (PMICs) for AI products are also booming. UMC is working with Qualcomm on silicon interposers, DTC (deep trench capacitors), and wafer-to wafer hybrid bonding, while Intel and UMC have partnered on 12nm FinFET, and the UMC-SanDisk cooperation is for memory chip stacking. The story cites unnamed industry sources. $UMC $QCOM $SNDK $INTC #semiconductors#

Busier fabs are lifting UMC's margins. Q3 wafer shipments hit a record, and 22nm reached a record 18.3% of wafer sales. UMC guides Q4 gross margin flat and cites rising demand for advanced packaging and silicon photonics. Its board also approved about $3.2B of added capex. @TradrETFs offers a 2X long daily ETF on $UMC: $UMCU. Investing in leveraged ETFs involves significant risk. Details at

Summary of UMC 2303 TT note on market worries vs. our view re-rating • UMC share price weak on worries over “no price hike in 2H26”
• We see 2H26 hikes are for selective customers (e.g. MTK 8”). → The broad-based hikes to be in 1Q27 (10-30%). ⬆️ Raise TP to NT$215 : Meaningful re-rating path into 2H26–2028 ☕️ 2H26–2027: Profitability optimization on Higher UTR + price hikes + improving mix
• 12” UTR → ~93% by end-2026 (Novatek/Samsung LSI 22/28nm + Apple Mac)
• 8” UTR → ~90% by end-2026, full loading by 2H27
• Pricing momentum extends into 1H27 (10–30% across nodes) 2028 ⬆️new growth phase from 2028
• Asset-light FinFET 12nm model , with Apple DDIC likely be the key driver 
• Optical full-solution model (SiPh/TFLN + interposer/advanced packaging) - TFLN EPS contribution of NT&0.7/NT$1.6 in 27/28. 💰 EPS lifted and target multiple to 25x 2027E EPS. Solid FCF + dividend yields intact. #UMC# #Optical# #TFLN#

in my culture (UMC PMC) making a lot of money is synonymous w/ adulthood. but this is not some cultural universal! many american adults are like, pretty poor! median household income in the US is about 90k. you can be a "full adult" who pulls no dough!

Abstracts of UMC (2303 TT, UMC) Acceleration in PIC/TFLN（薄膜铌酸锂 Thin‑Film Lithium‑Niobate） 📈 Buy | TP lifted to NT$160 - PIC/TFLN upside unlocks a higher-margin cycle • High-margin PIC business acceleration mainly driven by:
– Hyperlight (could have made significant progress with Google)
– TeraHop (key customers: Nvidia, GOOG) • TFLN 8” Wafer shipment expectations:
– 20k wafers/month by 4Q27
– 40k wafers/month by 4Q28 • PIC economics far superior to corporate average with Gross margin >70%, ASP ~$2.5k per 8” wafer (vs Normal 8” ASP below $1k), Expected EPS contribution of NT$0.7 in 2027 and NT$1.5 in 2028 • That said, TFLN will help UMC shift its product mix toward higher-value AI segments (including optics) • Possibility remains open for UMC to extend its PIC wafer business into packaging over the mid/long term In addition to PIC/TFLN, • UTR expected to keep rising, driven by: AI (incl. optics), CIS / ISP
and DDIC (benefiting from Apple moving Mac from 8” to 55nm) • Although the market has less appetite for the price-hike theme, visibility has been extended to 2H27 • Intel collaboration: Management earlier reiterated the partnership remains on track Tape-out targeted for 2027 on Intel 12, and we now expect the Capacity to be more than one phase #UMC# #PIC# #SiPh# #TFLN# #NVDA# #CPO#
