The call

Unisem is riding an AI chip demand wave with revenue up sharply, but margins are being squeezed from both ends: advanced work moving in house at TSMC and Samsung, commodity work undercut by Chinese OSATs.

Unisem assembles, packages, and tests computer chips for companies like Renesas and MACOM. It is hard to replace because it has long-standing customer relationships and factories outside China, but it is getting easier to copy because TSMC, Intel, and Samsung are now doing their own advanced packaging work, and Chinese competitors like JCET and Huatian are undercutting prices on the standard packaging work where Unisem makes most of its money. The stock price has tripled in a year based on hope that artificial intelligence demand will save the business, but the company's actual profits fell one-third in the first nine months of 2025 even though revenue grew, which means costs are rising faster than sales and the company's new factory in Gopeng has not yet paid off. The one thing that could turn this around is whether that Gopeng plant becomes profitable by late 2026 as promised, or whether margin pressure from cheaper Chinese factories keeps grinding away at what Unisem can earn.

Why
01
AI pressure: None apparent. AI chip demand is feeding Unisem's growth right now, not eating it; the risk is that demand cooling, not AI itself, hurts them. Could AI do the core job? Unlikely.
02
Bigger players: TSMC, Intel, Samsung advanced packaging. The chip giants are building in house advanced packaging, shrinking the high margin work that OSATs like Unisem used to get. Could a giant copy it? Yes, easily.
03
What protects it. Qualified customer relationships (Renesas, MACOM) that took years to certify, plus Malaysia's status as a China+1 alternative site.
What would change this call
Gopeng plant hits or misses guided profitability by Q4 FY26. Shows whether Unisem's capacity expansion is converting into durable margin gains.
Core net margin trend in Q2/H1 2026 results versus revenue growth. Shows whether Chinese OSAT price competition is compressing margins faster than volume can offset.
Completion terms and dilution impact of the RM742m private placement. Shows how much shareholder value is diluted to fund debt paydown and expansion.
Key numbers
  • 9M2025 net profit fell 33.6% YoY to RM34.52m (2025-09-30)
  • Bank borrowings doubled to RM406.4m from RM187.1m (2025-12-31)
  • FY26 guidance: 20 to 25% USD revenue growth (2026-02-25)
Named risks
  • Net profit falling despite revenue growth due to FX losses and ramp-up costs. Severity: high
  • Chinese OSATs undercutting price in commodity packaging where Unisem competes hardest. Severity: high
  • Bank debt doubled to RM406.4 million in FY2025, prompting dilutive RM742 million placement. Severity: medium
  • Gopeng plant profitability ramp delayed, previously slipped to Q4 FY26 target. Severity: medium
  • Equity priced for flawless AI upcycle narrative vulnerable to semiconductor sentiment correction. Severity: medium

Questions people ask
Is Unisem profitable in 2026?
Yes but unevenly. FY2025 net profit hit RM291.19 million on revenue of RM1.87 billion (+18.4% YoY), yet 9M2025 net profit fell 33.6% YoY to RM34.52 million despite 19% revenue growth, hurt by FX losses and Gopeng plant ramp-up costs, as reported October 2025.
Could AI replace Unisem?
No. Unisem performs physical semiconductor assembly, packaging, wafer bumping and test, which AI cannot execute. AI is instead a demand tailwind, since Unisem packages power-management and automotive chips feeding AI data-center infrastructure, per company commentary from April 2026.
Who owns Unisem?
Huatian Technology (Malaysia) Sdn Bhd, a unit of China's Tianshui Huatian, holds 44% following a 2019 takeover. Chairman John Chia Sin Tet holds roughly 20-28%. Malaysia's KWAP became a substantial shareholder with 6.05% on July 16, 2026, and Norway's Norges Bank raised its stake to 5.13% on July 24, 2026.
Who is Unisem's biggest competitor?
Globally, ASE and Amkor lead the OSAT industry with comparable Southeast Asian capacity. China's JCET, the largest Chinese OSAT, posted FY2025 revenue of RMB38.87 billion (+8.1% YoY as of December 31, 2025), undercutting Unisem on price in standard packaging.
Is Unisem stock overvalued?
It is priced for a flawless AI cycle. Shares rose about 111% year over year as of July 24, 2026, hitting a 52-week range of roughly RM1.81 to RM5.38, even as core net profit grew just 3.6% YoY to RM63 million in FY2025 while bank borrowings doubled.
What is Unisem's relationship with its parent company Huatian?
China's Tianshui Huatian Technology, together with chairman John Chia, completed a takeover of Unisem in 2019 and now holds 44% through Huatian Technology (Malaysia) Sdn Bhd as of July 16, 2026. Notably, Huatian itself operates as a competing OSAT business.
