Silicon Wafer Cycle Upswing Imminent, GlobalWafers Target Price Raised to NT$800

Overview

This UBS research report provides an analysis of GlobalWafers’ Q1 2026 results. While the company’s gross margin has come under pressure due to the absence of one-time subsidies, rising depreciation, and increasing costs, the silicon wafer industry’s cyclical dynamics and pricing outlook are improving. Demand is expanding from cloud AI to a wider range of end applications, driving a recovery across all wafer sizes. UBS views the near-term pullback as an opportunity to position for the structural upcycle in 2027–2028, and thus maintains a “Buy” rating while raising the 12-month target price from NT$700 to NT$800.

Core views

Demand and Capacity Utilization: During the Q1 earnings call, GlobalWafers shared a more optimistic view of the silicon wafer industry. Demand is spreading from cloud AI to a broader set of end applications, and the company has observed rising demand across all wafer sizes. Its existing 12-inch capacity (excluding new expansions) is fully utilized, and 8-inch capacity utilization is also increasing. UBS expects 12-inch silicon wafer capacity utilization to rise from 82% in 2025–2026 to 88% in 2027 and 94% in 2028; 8-inch utilization will climb from 79% in 2026 to 87%/94% in 2027/2028. Pricing Outlook: As industry supply tightens, GlobalWafers is negotiating with customers to raise 12-inch wafer prices in the second half of 2026 to offset rising depreciation and cost inflation. UBS believes the pricing environment will continue to improve, with new long-term contracts signed starting in H2 2026 reflecting higher prices. In addition, customer inventories are returning to more normalized, healthier levels. Short-Term Gross Margin Pressure: The report notes that the company still faces headwinds to its gross margin in the short term. Q1 2026 gross margin dropped to 20.8% from 25.7% in Q4 2025, primarily due to the absence of one-time subsidy income, higher depreciation, and rising costs. UBS has lowered its 2026 gross margin forecast to 21.4%, but anticipates that robust demand recovery, higher utilization, improved product mix, and more favorable pricing will push 2027 gross margin up sharply to 27.1%. Earnings Forecast Adjustments: Based on the more conservative gross margin outlook, UBS has cut its 2026 EPS estimate by 14%; however, buoyed by a stronger industry outlook, it has raised its 2027/2028 EPS forecasts by 3% and 10%, respectively. The report views any near-term pullback in the stock price as a buying opportunity to position for the structural upcycle in 2027–2028. Valuation Perspective: UBS has raised the target price from NT$700 to NT$800, based on a 3.6x 2027 forward P/B ratio (previously 3.2x), consistent with an upgraded long-term ROE forecast of 18.5% (up from 16.1%). This valuation multiple sits near the midpoint of the firm’s historical 1.5–6x range.

Analysis framework

UBS’s analysis follows a logical thread: demand recovery → rising capacity utilization → improving pricing → adjustments to gross margin and earnings forecasts → re-evaluation of valuation. First, by tracking management guidance from the Q1 earnings call and industry supply-and-demand data, the firm confirms that demand is broadening beyond AI and that inventories are normalizing. Next, based on expectations of rising industry capacity utilization, it concludes that the company will be able to raise prices in H2 2026. It then quantifies factors such as expected price hikes, rising depreciation, and cost inflation within its gross margin model, concluding that margins will be under pressure in the short term but will improve significantly starting in 2027. Finally, after revising earnings forecasts, it employs a price-to-book (P/B) relative valuation approach, referencing historical valuation ranges and factoring in the upward revision of long-term ROE projections to assign a higher target multiple and arrive at the new price target.

Methodology notes

• Industry/Industrial Analysis FrameworkSupply-demand framework

  The supply-demand balance determines price and capacity utilization

  The report infers the company’s ability to raise prices by analyzing trends in capacity utilization across wafer sizes (e.g., 12-inch utilization rising from 82% to 94%) and expectations of tightening industry supply. This is a typical application of the supply-demand framework: when demand recovers and capacity approaches full utilization, pricing power shifts to sellers.

• Company Fundamentals and Financial FrameworkOperating/Financial Leverage Analysis

  The impact of capacity utilization leverage on gross margin

  The report points out that 2027 gross margin will expand significantly because fixed costs (such as depreciation) are spread over a larger output as capacity utilization increases. This analytical approach highlights how even small changes in capacity utilization can have a leveraged effect on profitability in capital-intensive industries.

• Valuation MethodologyPB valuation

  Relative valuation based on the price-to-book (P/B) ratio

  The report uses a 3.6x 2027 forward P/B ratio to derive the target price. The underlying logic is that a company’s earning power (as measured by ROE) determines the premium it should command on its net assets; since the long-term ROE forecast has been raised from 16.1% to 18.5%, the appropriate P/B multiple has also increased accordingly.

• Industry/Industrial Analysis FrameworkInventory cycle (Kitchin)

  Customer inventory normalization and cyclical turning point

  The report mentions that customer inventories are moving toward normalization and healthier levels, which is a key signal for identifying semiconductor cycle turning points. Inventory cycle analysis suggests that once downstream inventories are depleted to reasonable levels, purchasing demand will be rekindled, driving upstream capacity utilization higher and prices back up.

Impact & implications

UBS believes that GlobalWafers’ recent gross margin pressures are temporary and that, as semiconductor demand undergoes a structural recovery in 2027–2028, the company’s earnings will experience strong growth. By raising its long-term ROE forecast and target valuation multiple, the report conveys confidence in the company’s fundamental improvement. It also points out that any stock price pullback caused by weaker-than-expected short-term gross margins should be viewed as a buying opportunity to position for the medium- to long-term upcycle.

Risks

• Fluctuations in end-market demand (e.g., economic contraction leading to lower semiconductor demand)
• Intensified industry competition and price wars (due to overcapacity from expansions)
• Depreciation and cost pressures from high capital expenditures
• Growing market share of mainland Chinese manufacturers
• Exchange rate volatility
• Risks associated with supply chain inventory adjustments
• Accelerating miniaturization in semiconductors, reducing wafer demand

What to watch

• The timing and magnitude of the 12-inch wafer price hike in H2 2026
• Whether customer inventory levels continue to normalize
• The pace of continued improvement in 8-inch capacity utilization
