Unimicron Technology (3037.TW)

Product mix improvement speed to accelerate from 2H26, with sustainable demand outlook in LT

NT$1,220.00

Pri c e:

NT$688.00

Upside:

77.3%

We joined Unimicron's 2Q26 result meeting today (July 29th).

Key takeaways include:

  • (1) Unimicron believes it has a high pricing power on ABF substrates, especially for those high-end products, and believes the GM should reach 50-60% in the mid to long term, but needs to continue to increase its moat and capability on R&D/mass production and build its owned supply chain.
  • (2) Unimicron announced the YM3 plant capacity expansion plan, and mentioned the new capacity has been fully booked by high-end customers. Unimicron also revised up its CAPEX in 2026E to be NT$53.7bn from NT$34bn previously (58% upward revision and now implying 110% YoY) and further increase its equipment budget by NT$17.6bn.
  • (3) For AI exposure, the company mentioned 60% of its ABF substrate and PCB revenue were contributed by AI related demand in 1H26, and it expects the number to expand to 70%+ for ABF substrate and 65-70% for PCB products in 2H26.
  • (4) For EMIB-T substrates, the company mentioned the mass volume shipment could start from 2027, and it targets to reach 50% yield rate for the products, which should be good enough to deliver a better than company's average GM, as customers continue to encourage suppliers to produce the EMIB-T substrates by raising the product pricing to protect low yield rate suppliers.
  • (5) For EMIB-T substrate, the substrate price will be much higher than CoWoS substrates if we exclude the interposer used in the packaging technology; moreover, theoretically, CoWoS substrate BOM cost should be much higher than EMIB-T substrate (assuming similar yield rate), making Unimicron focus more on EMIB-T technology.
  • (6) For BT substrates, the company will continue to transfer capacity

from BT substrate to high-end large body size ABF substrates, considering the much better pro fi tability and demand outlook; however, Unimicron mentioned it will only transfer the BT substrate capacity used to produce consumer related products to ABF substrates, but not those used to produce memory demand, as the memory related BT substrate demand still goes up signi fi cantly close to AI products' pro fi tability.

(7) For glass core substrates, Unimicron believes the mass production will not happen before 2029-2030, but it continues to work on the R&D investment on this technology. Unimicron mentioned this technology is a highly customized one, and it could not be fully supplied by a single substrate maker or packaging company considering the di ffi culty, and the company doesn't expect the glass core substrate to fully replace the organic substrate in the long term, as glass core substrate should only be used in speci fi c high-end design.

We maintain our Neutral rating, while we are positive on overall ABF pricing outlook, with the solid demand from high-end ABF substrates and expect Unimicron can continue to deliver good margin and earnings outlook thanks to the company's leading position in the high-end ABF substrate industry, despite the fact that we believe the company's AI HDI/PCB business GM outlook to remain sluggish considering low yield rate, making the company less attractive vs. ABF substrate peers.

Our positive view on the overall ABF substrate industry pricing uptrend (we believe ABF substrate LTA/spot price will increase by 10-15%/20%+ QoQ per quarter from 3Q26 through at least the end of 2027 - see here) should continue to drive the company's pro fi tability in coming quarters/years. In addition, we have started to see Taiwan ABF substrate companies have begun to sign LTAs with key AI customers for the next 3-5 years capacity, which not only suggests a better product mix in the long term, but also could increase the company's pro fi tability considering the incentive bene fi t (we believe the incentive bene fi t from LTAs could drive the company's OPM by 10ppt+ in the next 5 years in average, which is in-line with what we saw in the last upcycle in 2020-2023). Moreover, the company's new investment in ABF substrate capacity even after 2028 (Exhibit 1; We believe YM3 plant will start MP from 2029) should imply a solid demand outlook as the company mentioned all of its new capacity which will come on stream is mostly covered by LTA from high-end customers.

Overall speaking, we are generally positive on Taiwan ABF substrate suppliers, who should continue to enjoy a better pricing outlook in the next 2+ years, and expect the LTAs will suggest a good product mix in the long term; however, we maintain our relatively conservative view on Unimicron considering the company's track record on execution in the HDI business, and will continue to monitor the business outlook closely.

Maintain Neutral on Unimicron, and revise up our 2026E-28E EPS by 8-39% to re fl ect the above and raise our 12-m TP to NT$1,220 (from NT$1,140 previously).

Investment thesis, PT methodology and risks

Investment Thesis - Unimicron Technology

Unimicron is a key supplier of ABF substrates (25% market share in 2025) and BT substrates and also produces FPC/HDI/PCB products. We are Neutral rated on the shares given long-term growth opportunity prospects: (1) over 70% of ABF shipments are covered by long-term agreements (LTA), which limits pricing fl exibility and makes price hike less likely; (2) the company's execution track record has been weaker than peers; (3) capacity expansion plan remains slower than peers, constraining its ability to capture incremental AI demand. The current ABF substrates market is seeing more favorable supply demand outlook, and Unimicron is likely to see better pricing outlook to re fl ect rising material costs in the coming quarters. AI ABF account for 10% of the company's total revenue, but the growth is likely to be slower than peers due to the company continuing to lose market share to peers given its less favourable production yield and slow capacity expansion. Overall, we are Neutral rated on Unimicron given our outlook for the limited upside potential, barring ASIC AI servers, despite our generally positive view on the long term on pro fi tability trajectory.
