TSMC (TSM) Q1 2026 earnings review
HPC Dominance Shatters Margin Ceilings
TSMC delivered an explosive 1Q26 report, pushing revenue to $35.9 billion (+40.6% YoY) and obliterating historical profitability norms. Gross margin reached a staggering 66.2%, driven by relentless High-Performance Computing (HPC) demand, high utilization, and favorable foreign exchange rates. With advanced nodes (7nm and below) now commanding 74% of wafer revenue, TSMC has successfully decoupled from consumer hardware seasonality. Q2 guidance points to continued sequential growth, cementing the company's absolute pricing power in the AI hardware ecosystem.
🐂 Bull Case
Gross margins expanded 390 bps sequentially and 740 bps YoY to 66.2%. This completely overshoots the '53% and higher' long-term baseline management previously discussed, showing immense operating leverage and pricing power at the leading edge.
High-Performance Computing grew 20% sequentially and now represents 61% of total revenue. This completely insulated TSMC from the 11% sequential drop in Smartphone revenue.
🐻 Bear Case
Despite booming demand, inventory turnover days worsened from 74 to 80 days. Capital is being heavily tied up ahead of the N2 ramp, pushing free cash flow down slightly QoQ.
Automotive shrank 7% QoQ and now sits at just 4% of revenue. Consumer-facing segments still show no signs of a robust, independent recovery.
⚖️ Verdict: 🟢🟢
Very Bullish. The sheer scale of margin expansion proves TSMC holds unparalleled pricing power in the AI era. Any concerns about consumer electronics weakness are overwhelmed by HPC growth.
Key Themes
HPC Mix Shift Hits New High
The platform mix is officially reweighted. HPC grew 20% QoQ, driving its share of total revenue to an unprecedented 61% (up from 55% last quarter). This mix shift is structurally beneficial because HPC relies almost entirely on the highest-margin 3nm and 5nm nodes. The trend is Accelerating.
Operating Leverage in Advanced Nodes
Advanced technologies (7nm and below) accounted for 74% of wafer revenue. The massive scale of 5nm (36%) and 3nm (25%) production is generating immense operating leverage. Total operating expenses as a percentage of net revenue dropped to 8.3%, allowing Operating Margin to expand 410 bps sequentially to 58.1%.
Macro Tailwind: Favorable FX
Currency dynamics provided a substantial tailwind. The average USD/NTD exchange rate moved from 31.01 in 25Q4 to 31.59 in 26Q1. This 1.9% sequential depreciation of the NTD directly bolstered gross and operating margins, as TSMC collects USD revenue while incurring significant NTD-denominated costs.
Working Capital Drag from N2 Ramp
A specific data point contradicts the otherwise flawless operational narrative: Inventory Turnover Days reversed their positive trend, climbing from 74 days in 25Q4 to 80 days in 26Q1. Total inventories increased to NT$311.45 billion. Management explicitly blames the upcoming N2 node ramp and strong N3 demand. While building inventory for a new node is necessary, it is tying up significant working capital just as capital expenditures remain elevated.
Smartphone Seasonality Masking Weakness
Smartphone revenue fell 11% QoQ, dropping to 26% of total revenue. While management typically waves this off as 'seasonality,' the Decelerating demand in consumer electronics forces TSMC to rely entirely on AI data center build-outs to maintain top-line growth.
Automotive Continues to Lag
The Automotive segment is Reversing, shrinking 7% sequentially. It now represents just 4% of total revenue, down from 5% in 25Q4 and 25Q1. Calculating YoY, the segment grew roughly 8%—drastically underperforming the company's 35.1% total NTD revenue growth. This indicates sustained weakness in the broader automotive semiconductor market.
Other KPIs
Reversing slightly. Free cash flow decreased by NT$20.4 billion sequentially from 25Q4, primarily due to lower operating cash flow (NT$698.9B vs NT$725.5B in Q4). This was driven by the NT$151.09 billion negative change in working capital, tied directly to the N2 inventory ramp.
Accelerating. Up 58.3% YoY and 13.2% QoQ, massively outpacing the 8.4% QoQ revenue growth. This highlights the sheer profitability of the 3nm/5nm mix shift.
Stable. Down slightly from US$11.51 billion in 25Q4. TSMC continues to deploy massive capital to secure capacity for the N2 ramp and global expansions.
Guidance
Decelerating YoY, but Accelerating sequentially. The midpoint (US$39.6B) implies a 10.3% sequential increase over 1Q26, accelerating from the 6.4% QoQ growth just reported. However, implied YoY growth is roughly 31.6%, a deceleration from the massive 40.6% YoY growth printed in Q1.
Accelerating. The midpoint of 66.5% indicates continued margin expansion beyond the already record-breaking 66.2% achieved in Q1. This assumes an exchange rate of 1 USD to 31.7 NTD.
Stable. The midpoint of 57.5% represents a slight sequential deceleration from the 58.1% printed in Q1, likely reflecting R&D and operational costs scaling up ahead of the N2 volume production.
Key Questions
Gross Margin Ceiling
With gross margins now passing 66%, you have completely decoupled from your historical '53% and higher' framework. What is the new structural ceiling for margins in the Foundry 2.0 era, and how much of the current 66%+ is temporary utilization benefit versus permanent pricing power?
N2 Ramp and Working Capital
Inventory days spiked to 80, which you attribute to the N2 ramp. How much more working capital will be consumed before N2 reaches volume production, and when will we see the revenue crossover point where N2 begins contributing positively to cash flow?
Non-AI Market Recovery
Automotive shrank 7% and Smartphone 11% sequentially. If the HPC cycle were to normalize in late 2026, do you have visibility into a fundamental recovery in edge and consumer devices to absorb the capacity?
