SMIC Utilization Is High. Why Could Gross Margin Still Face Pressure? Depreciation, Yield, and Product Mix Explained

SMIC's Q1 data disclosed in mid-May 2026 showed that utilization reached 93.1%, a relatively high level. But this does not mean gross margin must rise sharply. Foundry profitability is not determined only by whether production lines are busy. It also depends on depreciation, yield, new-capacity ramp-up, wafer average selling price, and product mix. SMIC's Q1 gross margin was 20.1%, while Q2 guidance is 20%-22%. This suggests revenue and orders have support, but margins still need to cross both cost and mix hurdles.

Key Takeaways

• SMIC's Q1 utilization rate was 93.1%, above 89.6% in the same period last year.
• Q1 gross margin was 20.1%, and Q2 gross-margin guidance is 20%-22%.
• High utilization helps spread fixed costs, but it cannot fully offset depreciation, yield, and product-mix pressure.
• Earnings-call reports said Q1 depreciation and amortization rose nearly 26% year over year to USD1.088 billion, with depreciation as a share of revenue rising to about 44%.
• Wafer ASP improvement can support gross margin, but sustainability depends on customer demand and the share of higher-margin products.
• After Q2 earnings, utilization, depreciation, ASP, yield, and product mix should be evaluated together.

Why Does High Utilization Not Equal High Gross Margin?

High utilization is usually positive for foundry gross margin because a large portion of fab costs, including buildings, equipment, personnel, utilities, and facilities, is relatively fixed. The busier the production lines, the easier it is to spread fixed costs across more wafer shipments. But this is only one part of the gross-margin formula. If new capacity has just entered production, depreciation rises quickly, yield is still ramping, or orders mainly come from weaker-priced products, high utilization may still fail to deliver meaningful gross-margin improvement.

According to SMIC's Q1 2026 results announcement repost, the company disclosed in May 2026 that Q1 revenue was USD2.505 billion, gross margin was 20.1%, utilization was 93.1%, and capital expenditure was USD1.5628 billion. The company guided for Q2 revenue to grow 14%-16% quarter over quarter and gross margin to reach 20%-22%. These figures show that SMIC has confidence in revenue growth, but its gross-margin guidance remains relatively cautious.

Therefore, SMIC's Q2 should not be judged only by whether utilization stays high. If utilization is high, ASP rises, yield improves, and product mix becomes better, gross margin is more likely to land in the upper half of guidance. If only utilization is high while depreciation and lower-margin orders increase, gross margin may still face pressure.

Summary: High utilization can help SMIC spread fixed costs, but gross margin is also affected by depreciation, yield, ASP, and product mix. If new capacity is still ramping, depreciation pressure rises, or lower-margin orders increase, high utilization may not lead to a sharp gross-margin increase.

Why Does Depreciation Pressure Weaken the Benefit of High Utilization?

Depreciation is one of the easiest margin pressures to overlook in a foundry model. Wafer manufacturing requires heavy investment in fabs, cleanrooms, equipment, and supporting facilities. Once equipment enters production, depreciation gradually flows into costs. Even if utilization remains high, unit costs can still rise if new equipment depreciation grows faster, limiting gross-margin elasticity.

RTHK's earnings-call report noted that SMIC's Q1 depreciation and amortization rose nearly 26% year over year to USD1.088 billion, depreciation as a share of revenue increased to about 44%, and full-year total depreciation was expected to rise by about 30%. This explains why the market still asks whether gross margin can continue rising even when utilization is high.

Depreciation pressure is not automatically negative. It often comes from expansion and equipment investment, which may raise long-term capacity and customer-service capability. The issue is timing: depreciation can enter costs first, while new capacity, customer qualification, and product-mix improvement take time. If Q2 revenue grows faster than depreciation, margin pressure will ease. If depreciation rises quickly and ASP or yield improvement is insufficient, profitability may remain constrained.

Summary: Depreciation remains a key margin pressure even when utilization is high. If depreciation from new equipment and new capacity grows faster than revenue, ASP, and product-mix improvement, gross margin may struggle to rise meaningfully even with high line loading.

How Does Yield Ramp-Up Affect SMIC's Gross Margin?

Yield is the hidden variable connecting utilization and gross margin. High utilization means production lines are busy; high yield means the same wafer input can produce more good die. For a foundry, even small yield improvements can affect unit cost, delivery efficiency, and customer satisfaction. Conversely, if yields for new processes, new platforms, or new lines are still ramping, high utilization may only mean that costs and production hours are being fully consumed, not that profit is being fully released.

SMIC mainly focuses on mature nodes and specialty processes. Mature platforms usually have more stable yields, but new capacity, new customer introductions, and specialty-process platforms still go through ramp-up cycles. Customers need to verify performance, yield, delivery, and stability from trial production to mass production. This process affects the speed of revenue recognition and whether gross margin can improve quickly.

In Q2 earnings, yield may not be disclosed as a standalone figure, but investors can judge it indirectly through gross margin, utilization, product mix, and management comments on new-capacity ramp-up. If utilization is high but gross margin does not improve, investors should ask whether the issue is depreciation, pricing, or yield and product qualification still being in a ramp-up stage.

Summary: Yield is the hidden variable between utilization and gross margin. High utilization means lines are busy, but if yields for new capacity or new products are still ramping, unit costs may remain elevated and gross-margin improvement may be delayed.

Why Is Product Mix More Important Than Shipment Volume Alone?

Whether SMIC's gross margin can improve depends not only on how many wafers it ships, but also on what products it makes, which customers it serves, and what ASP and margin structure those products carry. Q1 revenue mix showed consumer electronics at 46.2%, smartphones at 18.9%, computers and tablets at 13.6%, industrial and automotive at 14.0%, and connectivity and wearables at 7.3%. This structure shows that consumer electronics remains the largest revenue source, while industrial and automotive demand and specialty processes also affect margin quality.

High utilization can mean two very different things. One scenario is that high-margin and high-ASP orders fully occupy capacity, which gives utilization stronger margin value. Another is that the company accepts lower-margin orders to fill lines, making revenue and utilization look solid while profit elasticity remains limited. For SMIC, the real Q2 question is whether product mix improves, not simply whether shipment volume increases.

Sina Finance's earnings-call report noted that the company was more optimistic about customer demand and orders on hand, and would continue tracking customer demand while flexibly allocating resources. If Q2 orders come more from sticky demand such as specialty processes, industrial and automotive, analog, and power management, gross margin support will be stronger. If growth mainly comes from lower-priced orders used to fill capacity, margin improvement will be limited.

Summary: SMIC's gross margin depends not only on how many wafers it ships, but also on who the customers are, what products are produced, and what ASP and margin structure those products carry. If high utilization is driven by a better product mix, margin quality is higher.

Can Wafer ASP Improvement Offset Depreciation and Yield Pressure?

Wafer average selling price is an important variable for offsetting depreciation and yield pressure. SMIC's Q1 gross-margin improvement was mainly driven by product-mix changes and higher average selling prices. National Business Daily and CNR Finance also noted in their Q1 results coverage that the company's Q2 guidance was 14%-16% sequential revenue growth and 20%-22% gross margin.

ASP improvement matters because it raises revenue per wafer and helps absorb depreciation, labor, energy, and yield-ramp costs. But ASP is not a one-way variable. If pricing improvement comes from short-term shortages, customer inventory building, or temporary tightness in selected products, sustainability needs verification. If it comes from a higher share of specialty processes, long-term customer orders, and higher product value, gross-margin improvement is more credible.

CLS also cited the company's Q2 revenue and gross-margin range. After earnings, investors should look at where actual gross margin lands within the 20%-22% range. If it is in the upper half, ASP, product mix, or cost absorption may be stronger. If it is near the lower end, the market will continue to focus on depreciation and pricing pressure.

Summary: Wafer ASP improvement is an important variable for offsetting depreciation and yield pressure. If Q2 average selling price continues rising and shipments grow at the same time, gross margin is more likely to hold guidance. If ASP improvement slows, profit elasticity from high utilization will weaken.

During New-Capacity Ramp-Up, Which Costs Are Released Before Revenue?

Another reason SMIC's gross margin may face pressure is the time gap in new-capacity ramp-up: costs come first, while revenue comes later. After new fabs, new equipment, and supporting systems enter the production stage, depreciation, personnel, energy, maintenance, and process-tuning costs appear relatively early. But customer qualification, product introduction, yield improvement, and stable mass production usually take longer. Even if utilization stays high, the profit contribution from new capacity may not be released at the same time.

This is why high utilization needs to be unpacked. High utilization on mature lines can usually improve unit costs directly. High utilization on new lines may still be in the ramp-up stage. Orders may be entering the lines, but yield, product mix, and customer mass-production timing may not yet be fully stable. If Q2 new capacity is mainly in ramp-up and qualification, gross margin may first absorb depreciation and tuning costs before revenue quality improves.

After earnings, investors should watch how management describes new capacity. If the company emphasizes sufficient orders, smooth customer introduction, and gradual yield improvement, the market may accept near-term gross-margin pressure more easily. If CapEx and depreciation continue rising while new-capacity revenue contribution, ASP, and yield signals are insufficient, the support from high utilization will be weaker.

Summary: During new-capacity ramp-up, depreciation, personnel, energy, and tuning costs often appear before revenue. If customer qualification and yield improvement lag, high utilization may not immediately translate into margin elasticity. Margin pressure will ease only when new capacity is steadily absorbed by high-quality orders.

What Risks Could Push Gross Margin Below Expectations Even With High Utilization?

High utilization does not eliminate gross-margin risk. For SMIC, the key risk is several pressures appearing at the same time: higher depreciation, slow yield ramp-up, ASP improvement missing expectations, a higher share of lower-margin orders, consumer-electronics demand volatility, intensified mature-node pricing competition, and changes in customer inventory timing.

Policy and export restrictions are also external variables. Foundry CapEx, equipment procurement, customer structure, and order timing may all be affected by the external environment. SMIC has demand support as an important mature-node and specialty-process foundry, but short-term share prices may still be affected by gross margin, guidance, and external policy expectations.

Summary: High utilization does not remove gross-margin risk. If two or more variables among depreciation, yield, ASP, and product mix weaken at the same time, SMIC's margins may miss market expectations even if revenue grows.

What Gross-Margin Signals Should Investors Track After SMIC Reports?

After SMIC reports, the most important question is whether high utilization truly converts into gross-margin elasticity. If utilization is high but gross margin sits near the lower end of guidance, depreciation, ASP, or product mix may still be suppressing profitability. If utilization is high, ASP improves, and gross margin lands in the upper half of guidance, the quality of the recovery will look stronger.

When observing Hong Kong-listed semiconductor names such as SMIC, investors should also pay attention to Hong Kong stock liquidity, bid-ask spreads, order types, FX rates, A/H premium or discount, and fee rules after earnings. Users can use Biya to follow relevant available securities and check market categories through the Hong Kong stock list. On fees, Biya's pricing page shows that Hong Kong stock trading commission is 0.03% of transaction value, with a minimum of HKD7 per order, and the platform fee is 0.03% of transaction value, with a minimum of HKD8 per order. Trading fees, settlement transaction fees, transaction levies, stamp duty, external costs, and other applicable fees should be based on the Biya pricing page, the order page, and the platform's latest rules. Service availability depends on the user's location, identity verification results, platform rules, and applicable laws and regulations.

SMIC's later official disclosures can be checked through HKEXnews, the SSE listed-company announcement search, and the company's investor relations channels. After earnings, if management provides clearer explanations of depreciation, capacity ramp-up, customer demand, and product mix, the market will be better able to judge the margin quality behind high utilization.

Summary: After SMIC reports, investors should not only ask whether utilization is high. ASP, depreciation, yield, and product mix must improve together. Only when these variables move in the same direction can high utilization truly translate into margin elasticity.

FAQ

Why Could SMIC's Gross Margin Still Face Pressure When Utilization Is High?

High utilization helps spread fixed costs, but depreciation, yield, new-capacity ramp-up, ASP, and product mix still affect gross margin. If depreciation rises quickly, lower-margin orders increase, or yield ramps slowly, gross margin may still face pressure.

Why Does Depreciation Affect SMIC's Gross Margin?

Foundries require heavy investment in equipment and fabs. After new equipment enters production, depreciation becomes part of production cost. If depreciation grows faster than revenue, ASP, and product-mix improvement, unit costs rise and gross margin becomes harder to lift.

How Does Yield Affect Foundry Profitability?

Yield determines how many good products can be delivered from the same wafer input. Lower yield raises unit cost, especially during ramp-up for new lines, new products, and specialty-process platforms, making the impact on gross margin more visible.

Can Higher Wafer ASP Fully Offset Cost Pressure?

Not necessarily. Higher ASP helps revenue and gross margin, but if depreciation, yield issues, or lower-margin orders create greater pressure, gross margin can still be constrained. Q2 needs to show whether ASP improvement moves together with shipments and product mix.

Why Is SMIC's Q2 Gross-Margin Focus 20%-22%?

20%-22% is the Q2 gross-margin guidance range provided after Q1. If actual gross margin lands in the upper half of the range, pricing, product mix, or cost absorption may be stronger. If it falls below the range, depreciation, ASP, and yield pressure need closer attention.

What Risks Matter When Trading SMIC After Earnings?

Key risks include semiconductor-cycle volatility, mature-node price competition, A/H share-price differences, Hong Kong stock liquidity, higher-than-expected CapEx, wafer-price declines, gross margin below guidance, and policy or export restrictions.
