Higher AI thermal content value drives upward revision to Jentech's long-term growth outlook

Overview

JPMorgan believes Jentech Precision Industrial Co., as a global leading supplier of package-level thermal components, will benefit from upgrades to AI chip thermal architectures. Following strong 2Q26 revenue growth, the report raises medium- to long-term earnings forecasts and maintains an Overweight rating.

Core views

The core thesis is higher thermal-component specifications and content value per chip for next-generation GPUs and ASICs. Analysts expect the potential Rubin Ultra GPU design of a "stiffener frame + one-piece lid + additional screws" to generate significant incremental value. Continued vapor-chamber specification upgrades for AMD GPUs and cloud-service-provider ASICs should also expand Jentech's structural growth opportunity. In the near term, GPU customer shipment ramps and a higher AI product mix are expected to further improve 3Q26 revenue and gross margin.

Analysis framework

The report analyzes product content value, customer-platform iterations, quarterly revenue and gross-margin forecasts, earnings-estimate revisions, and P/E valuation, using 2028E P/E as the basis for its target-price valuation.

Methodology notes

• Fundamental ResearchProduct Content Value Analysis

  Estimate changes in thermal-component value per system by chip platform

  By comparing the current Rubin single-piece-lid design with a potential Rubin Ultra multi-component design, the analysis assesses the incremental revenue and earnings contribution from vapor chambers, stiffener frames, lids, screws, and other components.

• Valuation methodsP/E Valuation Method

  Derive target price using a forward P/E multiple

  The target price uses 30x 2028E P/E, referencing the company's three-year average P/E since the start of the AI server upcycle.

• Earnings ForecastingCombination of Top-Down and Bottom-Up Approaches

  Revise earnings forecasts based on customer shipments, product mix, and content value

  The report maintains its 2026 EPS forecast and raises 2027 and 2028 EPS forecasts to reflect stronger GPU content-value growth.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Jentech Precision Industrial Co.（3653.TW）

  Covered company

  Strengths

  Global-leading package-level thermal-component manufacturing capability; product and manufacturing advantages in vapor chambers, stiffener frames, and various lids; benefits from AI chip thermal upgrades while expanding into cold plates, CPU server sockets, and CPO switch ASIC markets.

  Weaknesses

  Valuation already reflects high growth expectations, and earnings delivery is highly dependent on AI customer platform iterations and product-mix improvement.

  Comparison

  The target price is based on 30x 2028E P/E, broadly in line with the company's three-year average P/E since the start of the AI server upcycle.

  Risks

  Slower adoption of microchannel lids; new competitors in the high-end vapor-chamber market; and new thermal technologies such as silicon-integrated microcoolers and CoWoP that could remove vapor chambers or lower their specifications.

• ADVANCED MICRO DEVICES INC（US.AMD）

  Potential demand-driving customer/platform-related party

  Strengths

  Upgrades in AMD GPU thermal specifications are viewed as a supporting factor for growth in Jentech vapor-chamber demand.

  Weaknesses

  The report does not provide financial or valuation analysis of AMD itself.

  Comparison

  Along with the Rubin Ultra GPU opportunity, AMD-related opportunities constitute a driver of next-generation AI chip thermal demand for Jentech.

  Risks

  If AMD GPU product timing or thermal solutions fall short of expectations, demand pull-through for Jentech could weaken.

Impact & implications

If AI GPU and ASIC platforms upgrade their thermal architectures as expected, Jentech could achieve revenue growth and margin expansion above that of a traditional components cycle. The report forecasts revenue to rise from NT$20,276m in 2025 to NT$82,546m in 2028, and adjusted EPS from NT$36.68 to NT$206.54; however, the investment thesis is highly sensitive to the implementation of new platform designs, customer shipment schedules, and high-end thermal technology roadmaps.

Risks

• Slower-than-expected adoption of microchannel lids.
• Intensifying competition in the high-end vapor-chamber market.
• Alternative thermal technologies such as silicon-integrated microcoolers and CoWoP could lead to vapor chambers being removed or their specifications being downgraded.
• GPU customer shipment ramps fall short of expectations.
• Next-generation GPU designs have not yet been fully finalized, creating uncertainty around higher content value per unit.
• High valuation entails demanding earnings-delivery requirements.

What to watch

• Whether Rubin Ultra GPUs ultimately adopt a thermal structure comprising a stiffener frame, one-piece lid, and additional screws.
• Whether GPU customer shipment ramps and 3Q26 revenue can meet the NT$9.7bn forecast.
• The actual extent of gross-margin improvement from a higher AI chip product mix.
• Progress in vapor-chamber specification upgrades for AMD GPUs and cloud-service-provider ASICs.
• Customer adoption and revenue contribution from new products including cold plates, CPU server sockets, and CPO switch ASICs.
• Order conversion and earnings delivery following the upward revisions to 2027-2028 EPS.
