GlobalWafers' Near-Term Guidance Is Muted, While New-Fab Ramp-Up in 2027 and Spot Price Increases Support Long-Term Improvement

Overview

This report summarizes key takeaways from discussions with GlobalWafers during J.P. Morgan's Asia Technology Tour, focusing on the 2026—2027 operating outlook, the Italian plant fire, wafer pricing, U.S. capacity expansion, SiC carrier substrates, and stock expectations. The report remains cautious on near-term earnings and valuation while recognizing the long-term growth potential from new capacity and profit improvement after 2027.

Core views

GlobalWafers maintained relatively muted guidance for 2026: full-year revenue is expected to be flat to slightly higher year over year, while gross margin in the second half of 2026 is expected to be broadly the same as in the first half. The company is more positive about 2027 because the Texas 12-inch fab, Missouri 12-inch SOI fab, and Italian 12-inch fab are expected to begin making significant revenue contributions and drive a marked improvement in the company's overall gross margin. Depreciation expense is expected to be approximately NT$12bn in 2026 and to increase slightly year over year in 2027, making the smooth ramp-up of new capacity and its ability to generate sufficient revenue important conditions for profit improvement. The company attributed its weak 2026 revenue guidance to the fire at the Italian plant in late July. Eight-inch products account for approximately 25% of GlobalWafers' total revenue, while 12-inch products account for more than 60%. The company has four 8-inch production sites worldwide, and the Italian plant accounts for approximately 30% of its global 8-inch capacity. The company stated that equipment damage was limited, epitaxial reactors have fully recovered, and losses from the incident will be covered by insurance. These factors reduce the long-term impact on assets, but the fire's near-term production disruption remains the direct cause of pressure on 2026 revenue. On pricing, most of GlobalWafers' 12-inch wafer shipments are covered by long-term agreements, with spot orders accounting for approximately 20%—30%. Tightening supply and rush orders are pushing spot prices higher, and the company expects 12-inch spot prices to be slightly above long-term agreement prices by the fourth quarter of 2026. Selling prices and margins do not move in tandem across regions: average selling prices rank the United States above Europe and Europe above Asia, whereas gross margins rank Asia above Europe and Europe above the United States, primarily reflecting differences in depreciation and operating costs. Most 8-inch shipments are not protected by long-term agreements. J.P. Morgan therefore emphasizes that U.S. production sites must secure significantly higher selling prices to cover high depreciation costs and that investors need to set reasonable margin expectations for the U.S. business. U.S. capacity expansion will proceed in phases. The existing building can accommodate both Phase 1 and Phase 2 facilities, and the company plans to eliminate Phase 1 bottlenecks before constructing Phase 2. Equipment lead times are lengthening, reaching up to 18 months. GlobalWafers stated that it will seek government subsidies and long-term agreement support before proceeding with Phase 2. The newly signed long-term agreement with Micron will commence in 2027, but the specific allocation of Micron's US$500mn strategic financing between equipment investment and long-term agreement prepayments has not been disclosed, nor has the planned timeline for the U.S. Phase 2 project. This leaves uncertainty over the pace and funding structure of the expansion. For SiC carrier substrates used in advanced packaging, the company expects its solution to be ready and enter small-volume production in 2027, but whether it can ramp further in 2028 will depend on customer demand and the pace of adoption. Current mainstream solutions include CVD polycrystalline SiC and PVT polycrystalline SiC. PVT monocrystalline SiC offers better heat dissipation but still costs several times as much as polycrystalline SiC, which may limit its adoption. The company's chief technology officer will deliver a presentation at the upcoming SEMICON Taiwan and provide further updates. At the stock level, J.P. Morgan identifies the magnitude and timing of price increases as key areas to monitor. Because GlobalWafers' share price has already risen on elevated expectations, whether actual pricing benefits can exceed the market's optimistic expectations is more important than the mere occurrence of price increases. The report believes that the earnings outlook for the second half of 2026 is insufficient to attract short-term investors, but forecasts an 88% CAGR in operating profit from 2026 to 2028, making sequential earnings improvement appealing to long-term investors. At the same time, valuation must be taken into consideration. The latest disclosed rating is Neutral, with a target price of NT$800, compared with a closing price of NT$1,010.00 as of August 24, 2026.

Analysis framework

The report primarily draws on company discussions during the technology tour. It first compares 2026 guidance with the 2027 outlook and then analyzes the Italian fire's impact on product mix and capacity. It subsequently assesses pricing and cost pass-through by examining long-term agreements, spot orders, and regional differences in selling prices and gross margins, while evaluating U.S. capacity expansion based on equipment lead times, subsidies, customer agreements, and financing arrangements. Finally, the report incorporates SiC technology pathways, the pace of customer adoption, earnings growth, and market expectations into its stock assessment.

Methodology notes

• Industry/Sector Analysis FrameworkSupply-demand framework

  Analysis of silicon wafer supply and demand, long-term agreements, and spot prices

  The report assesses price changes based on tight supply, rush orders, the proportion covered by long-term agreements, and the share of spot orders, and analyzes when price increases can translate into revenue and profit.

• Industry/Sector Analysis FrameworkVolume-price decomposition

  Decomposition of capacity contributions, selling prices, and gross margins

  The report separately examines output contributions from new fabs, regional selling prices, depreciation, and operating costs to explain why revenue growth and gross margin improvement may not occur in tandem.

• Event Strategy and Behavioral FinanceEvent-driven analysis

  Assessment of the Italian plant fire's impact

  Based on the timing of the fire, affected capacity, equipment recovery, and insurance coverage, the report distinguishes the incident's short-term impact on 2026 operations from its long-term impact on assets.

• Event Strategy and Behavioral FinanceExpectation Gap/Expectation Management

  Comparison of actual pricing benefits with optimistic market expectations

  The report believes the share price already reflects elevated expectations, so the key question is not whether prices will rise, but whether the magnitude and timing of the increases can exceed the optimistic assumptions already priced in by the market.

Impact & implications

The report believes that the fire disruption and high depreciation will weigh on GlobalWafers' near-term revenue and margins in 2026, but higher 12-inch spot prices, contributions from new fabs, and the Micron long-term agreement could drive earnings improvement after 2027. Whether the U.S. business can secure higher selling prices to cover depreciation, whether capacity expansion can proceed as planned, and whether actual pricing benefits can exceed elevated market expectations will determine whether long-term growth translates into share-price support.

Risks

• The Italian plant fire is affecting 2026 revenue, although equipment damage was limited, epitaxial reactors have recovered, and insurance coverage is in place.
• Depreciation and operating costs are very high in the U.S. business, and margins could fall below market expectations if selling prices are insufficient.
• The timeline for the U.S. Phase 2 project and the composition of Micron's US$500mn financing have not been disclosed, creating uncertainty over the pace of expansion and funding arrangements.
• Whether SiC carrier substrates can ramp in 2028 depends on customer adoption, while PVT monocrystalline SiC still costs several times as much as polycrystalline products.
• The share price already reflects elevated optimistic expectations, and valuation could come under pressure if actual pricing benefits fall short.
