VPEC (2455) Report Interpretation

Overview

This chairman-visit update focuses on whether VPEC can convert strong AI data-center optical demand into sustained revenue growth. Goldman Sachs remains positive, pointing to better InP substrate availability, planned MOCVD additions, and progress in new epiwafer products.

Core views

Goldman Sachs hosted VPEC's chairman and CFO on 3 September during Semicon Taiwan and reports that management remains positive on optoelectronics. The company sees its opportunity supported by the AI infrastructure cycle, optical-networking specification upgrades, customer penetration, and product expansion. Goldman Sachs says VPEC's strong July and August revenue reinforces its view that AI data-center optical-networking demand is robust, while improved InP substrate supply should remove part of a prior supply constraint. The institution therefore maintains Buy and a 12-month target price of NT$793. On InP substrates, management said supply is improving and should continue to support revenue growth over coming months. VPEC plans to continue seeking export permissions, expand its supplier base to four or more InP substrate suppliers, and have more customers provide substrates for VPEC to process. These measures are intended to narrow the gap between available material and demand. Capacity remains a central part of the growth case. Strong demand has extended MOCVD lead times from six months in late 2025 to eight to 12 months currently. VPEC has 62 MOCVD tools, is installing five that are expected to contribute capacity in January 2027, and expects another two to begin operating in the third quarter of 2027, bringing the total to 69. Management is also planning a third factory near its existing production sites to support further expansion. It noted that MOCVD capacity can be shared among epiwafer products, including a potential shift of capacity from smartphone GaAs epiwafers for power amplifiers toward AI data-center applications. For EML base epiwafers, management said product qualification and capacity preparation are on track. The products target 100G and 200G applications. Of five customers currently engaged, two to three Asian customers are expected to begin mass production in 2027E. Management intends to remain focused on epiwafers rather than compete with customers by moving downstream into EML, because such expansion would reduce gross margin. It cited high base-epiwafer yields, customer-specific EML epiwafer designs, long operating experience, and available capacity as barriers that help attract customers. In CW lasers, management expects one to two customers to be in mass production during 2026E and another two US customers to enter mass production in 2027E. These customers use InP epiwafers for 100mW-and-higher CW lasers. For co-packaged optics, management said 300mW and 400mW solutions remain difficult because of thermal issues. Customers are currently working on 100mW and power-amplifier solutions that can be used in near-packaged optics, while continuing development of 300mW and 400mW CPO solutions. VPEC supplies InP epiwafers for both 100mW and power-amplifier applications. Goldman Sachs derives its NT$793 target using a discounted P/E approach: it applies a 22.2x target P/E to 2029E EPS and discounts that value back to 2027E using a 10.5% cost of equity, based on beta of 1.7x, a 1.6% risk-free rate, and a 5.1% market-risk premium. The target P/E is based on a 0.4x PEG & M ratio derived from the average of photonics supply-chain peers. The target compares with a NT$500 share price as of the 7 September 2026 close, implying 58.6% upside.

Analysis framework

The report combines management commentary from Semicon Taiwan with recent revenue momentum, supply availability, equipment-capacity plans, product qualification progress, and customer production timelines. It then values VPEC through a target P/E applied to 2029E EPS and discounted back to 2027E using a cost-of-equity assumption.

• VPEC (2455.TW)

  Primary covered company and beneficiary of AI data-center optical-networking demand, improving InP supply, and expanded epiwafer capacity.

  Strengths

  Strong July and August revenue, high base-epiwafer yields, customer-specific designs that raise entry barriers, epiwafer experience, and planned MOCVD expansion.

  Weaknesses

  InP substrate availability has remained a constraint relative to demand, and CPO high-power solutions face thermal challenges.

  Comparison

  Target P/E is anchored to an average PEG & M ratio from photonics supply-chain peers.

  Risks

  Slower-than-expected SiPh ramp, weaker smartphone microelectronics demand, or IDM in-house EPI wafer supply.

Impact & implications

Goldman Sachs views improving substrate supply and planned manufacturing additions as enabling VPEC to capture continued optical-networking demand from AI data centers. Product qualification and expected customer ramps in EML base epiwafers and CW lasers provide additional potential growth avenues into 2027E.

Risks

• SiPh business ramp-up could be slower than expected.
• Microelectronics demand from smartphone clients could be weaker than expected.
• IDMs could supply EPI wafers internally.
