Apple's interest in CXMT memory strengthens the case for a re-rating of China's DRAM and advanced packaging supply chain
Citigroup believes that Apple's reported pursuit of policy approval to procure CXMT DRAM, despite approval uncertainty, significantly validates CXMT's technological progress and benefits backend equipment and OSAT suppliers, with a preference for ASMPT and JCET.
- Apple reportedly sought approval from the US government to procure CXMT memory, citing rising memory costs and tight supply.
- Citigroup believes Apple's consideration alone shifts CXMT from a 'China domestic substitution' narrative to that of a 'credible fourth-largest global DRAM manufacturer.'
- CXMT's LPDDR5X 12Gb/16Gb die capacity and 10667Mbps speed are considered suitable for high-end smartphones, tablets and notebook applications.
- Beneficiaries across the supply chain include equipment vendors and OSAT service providers; Citigroup prefers ASMPT and JCET within its coverage.
- Key uncertainties include US policy approval, potential BIS Entity List restrictions, export controls and fluctuations in AI/advanced packaging demand.
Report interpretation
Overview
This report discusses the implications for the Greater China semiconductor supply chain of Apple's reported intention to procure CXMT memory. Citigroup believes that although CXMT is on the Pentagon 1260H Chinese Military Company List and US government approval remains highly uncertain, Apple's consideration of CXMT as a potential supplier constitutes strong endorsement of its product reliability and technological progress. The event could improve market perceptions of CXMT and drive a re-rating of China's DRAM, backend equipment, advanced packaging and OSAT supply chains.
Core views
The core views are: first, Apple's potential procurement intention does not mean approval has been granted, but its signaling value is stronger than the near-term order itself; second, CXMT is no longer merely a domestic substitution theme, but is being reassessed by the market as a more globally competitive DRAM manufacturer; third, tight memory supply and improved high-end LPDDR5X capabilities together support opportunities across CXMT's supply chain; fourth, equipment and testing and packaging segments are more direct beneficiaries, with Citigroup preferring ASMPT and JCET.
Analysis framework
The report analyzes the news event as a catalyst, combining policy constraints, product technology specifications, supply-chain transmission and valuation frameworks. It uses 2027E P/E valuation for ASMPT and 2027E P/B valuation for JCET, TSHT and TFME, while explaining target prices through AI-driven advanced packaging demand, OSAT capacity utilization and industry re-rating.
Methodology notes
Assess ASMPT using a 2027E P/E multiple
ASMPT's HK$180 target price is based on 37x 2027E P/E. Citigroup believes AI-driven advanced packaging orders, TCB demand and recovery in mainstream SEMI and SMT can support a premium valuation.
Assess Chinese OSAT companies using 2027E P/B multiples
JCET, TSHT and TFME use 6.0x, 4.0x and 6.5x 2027E P/B, respectively, primarily supported by AI proliferation, advanced packaging demand and tightening industry supply.
Use Apple's potential procurement intention to assess CXMT's technological credibility
Even without procurement approval, Apple's consideration of CXMT as a supplier is viewed as validation of CXMT's reliability, LPDDR5X capabilities and tight memory supply and demand.

Impact & implications
The investment implication of this event is that the global credibility of China's DRAM supply chain may be repriced, with market attention expanding from simple domestic substitution to high-end memory supply capabilities and validation by global customers. Potential beneficiaries may extend from CXMT to backend equipment, advanced packaging, TCB, HBM-related applications and OSAT capital expenditure, although policy approval and export restrictions remain key risks determining valuation sensitivity.
Risks
- It remains uncertain whether the US government will approve Apple's procurement of CXMT DRAM.
- CXMT may face stricter restrictions in the future, such as inclusion on the BIS Entity List.
- US export restrictions may expand to backend equipment, affecting advanced packaging and OSAT capacity expansion.
- Slower AI infrastructure investment could weaken demand for TCB, HBM and OSAT.
- If advanced packaging capacity expands faster than demand, industry utilization may decline.
- Memory manufacturers may internalize backend packaging, reducing opportunities for independent OSAT providers.
- Geopolitical tensions could weaken overseas demand for the companies involved.
- Alternative technologies such as hybrid bonding could reduce some TCB demand.
