Continued Capex spree underpins strong business outlook
Maintain Rating: BUY | PO: 800.00 TWD | Price: 703.00 TWD
YTD equipment buys tracks 82% of its '26 capex guidance
ASE has filed 152 equipment buys and 101 facility construction announcements through late September. The spending on equipment YTD has reached NT$273bn, tracking 82% of its '26 capex guidance of US$10.5bn (has revised up from US$8.5bn) not yet considering their land and facility purchase. The equipment buy should mainly be for 2.5D packaging and chip probing, reflecting accelerated capacity expansion amid strong demand for its LEAP business from its own project wins and its foundry partner's outsourcing. To secure sufficient facility infrastructure to house additional capacity, ASE has announced NT$112bn of spending YTD on facility and clean room construction contracts, with these projects expected to progressively complete through 2027-2028.
Solid sales/margins across the board sponsor heavy capex
Following ASE's July announcements to acquire new lands and facilities in Kaohsiung and Taoyuan, the company announced another NT$2.15bn facility acquisition in Singapore to support the future testing expansion needs in its Singapore subsidiary as its major customers request supply base diversification. Despite rising depreciation from heavy capex investments and additional funding needs, we forecast ASE's IC ATM sales to +37% CAGR from '26-28 while GMs should improve to 33.8%/37% in '27/28 (from 28.3% in 2026) on solid packaging and testing demand for AI chipsets (BofAe LEAP sales US$4/10/13bn in 2026/27/28) and fast improving mainstream business outlook.
Decent earnings support re-rating despite funding needs
We keep Buy on ASE with NT$800 PO on 20x 2H27-1H28 P/E and maintain EPS for '26/27/28E at NT$18/31/45. While additional funding may be required to finance its aggressive spending on expansion and R&D projects, we believe the decent customer commitment and ROE of 25-30%+ from LEAP business should justify the funding costs.

Company Description
Established in 1984 and headquartered in Taiwan, ASE Technology Holding is the no.1 outsourced assembly and testing (OSAT) firm globally, in terms of market share by revenue. ASE acquired Siliconware Precision (SPIL) in 2018, and had acquired USI in 2010, which became its EMS business segment providing synergies in system-level packaging. 2 shares = 1 ADR.
Investment Rationale
We rate ASE Buy, factoring in the company's opportunity in advanced packaging and testing evidenced in TSMC's outsourcing and its own heavy capex investment. The strategy shift should allow the company to capture fast growing addressable market in high performance computing applications and improves its margins. ASE could maintain its leading position in the Outsourced Semiconductor Assembly and Test (OSAT) universe, owing to its well-established footprints and widespread service offerings.

Price objective basis & risk
ASE Technology Holding (XSRIF / ASX)
We value ASE Technology Holding at NT$800 per share (US$51 for ADR), based on 20x 2H27-1H28E P/E, above its historical range of 5-26x, in view of its solidified industry position in AI era. We use P/E ratio to value ASE as the company has been able to maintain healthy profitability through the cycles in the past 20 years due to consolidating industry landscape supporting a more benign supply/demand and keeping pricing and margins less cyclical.
Downside risks to our PO are 1) share loss and/or ASP erosion owing to Chinese players' cannibalization and/or ASE's worsening execution, 2) weakening end demand due to uncontrollable matters, such as macro halt and/or geopolitical tensions, 3) regulatory issues that could hinder ASE from generating synergies and benefit its competitors.
