TSMC's 70% Capacity Surge Meets a Spy Conviction: The Chip Giant's Two-Front Battle

TSMC shares fell 4.2% amid AI selloff, but 2nm capacity grows 70% annually, revenue jumps 40% YoY, and a landmark spy conviction boosts legal safeguards.

The world's most valuable chipmaker is fighting on two fronts at once. On one side, TSMC is racing to scale its next-generation 2-nanometer production by 70% annually through 2028. On the other, it just secured a landmark legal victory against industrial espionage. Yet on Tuesday, none of that mattered: the stock slid 4.2% to $387.96, dragged down by a broad selloff in AI-linked names after reports that OpenAI had missed internal growth targets.

The day's decline, however, tells only a sliver of the story. Over the past twelve months, TSMC shares have more than doubled, and the 50-day moving average of $325.95 sits roughly 19% below the current price. The company's fundamentals remain exceptionally strong, with first-quarter 2026 revenue hitting $35.9 billion — a 40% year-over-year jump — and management guiding for second-quarter sales between $39.0 billion and $40.2 billion at a gross margin of 65.5% to 67.5%.

The 2nm Expansion Machine

TSMC is pouring resources into its most advanced node with uncommon intensity. Five fabrication sites — two in Hsinchu and three in Kaohsiung — are being ramped up to support the 2nm process, which began production in the fourth quarter of 2025. The first-year output volume is expected to be 45% higher than the comparable launch year for the 3nm technology. By 2028, total 2nm capacity will expand at a compound annual growth rate of 70%.

The company isn't neglecting its existing strengths either. The 3nm capacity base is growing at roughly 25% annually through 2027, ensuring a steady pipeline for clients who haven't yet migrated to the bleeding edge.

Packaging as a Profit Engine

Beyond traditional chip fabrication, TSMC is making aggressive bets on advanced packaging. CoWoS (Chip-on-Wafer-on-Substrate) monthly capacity is slated to reach 120,000 wafers by the end of 2026 and 140,000 by the end of 2027. The annual growth rate for this technology ranges between 80% and over 90%, making it an increasingly important driver of earnings.

On the lithography front, Co-COO Kevin Zhang clarified that ASML's new High-NA EUV equipment won't be needed for the A13 process node. The company doesn't expect to deploy that technology until at least 2029.

Global Footprint, Local Tailwinds

TSMC's international expansion is accelerating. Output at its first Arizona facility is projected to increase 80% in 2026, while the plant in Kumamoto, Japan, is targeting a 130% jump. In Europe, the company opened a design center in Munich during the third quarter of 2025.

Back home, Taiwan's Financial Supervisory Commission handed TSMC an unexpected boost. On April 25, the regulator raised the single-stock cap for local equity funds from 10% to 25% — a move markets have dubbed the "TSMC clause." The change could unlock significant capital inflows into the stock from domestic institutional investors.

A Landmark Spy Conviction

A Taiwanese court delivered a watershed ruling on April 27, sentencing a former TSMC engineer to ten years in prison for stealing confidential 2nm process data. Three other employees received sentences ranging from two to six years. The recipient of the stolen information was Tokyo Electron, the Japanese equipment maker.

The case marks the first time a company has been penalized under Taiwan's national security law. Tokyo Electron Taiwan was ordered to pay approximately NT$150 million (roughly $4.8 million), with about $3.2 million of that amount going directly to TSMC. The fine is suspended for three years on probation. Investigators discovered detailed blueprints on Tokyo Electron's servers after the former engineer — who had moved to the Japanese firm's marketing division — persuaded former colleagues to leak internal documents. The goal, prosecutors said, was to secure lucrative contracts for the 2nm production line.

The Bigger Picture

TSMC controls more than 90% of the world's advanced chip manufacturing capacity. That dominance is a double-edged sword. Barclays recently raised its price target on the stock to $470, citing sustained AI chip demand. But geopolitical tensions between China and Taiwan, coupled with tightening US export controls, keep compliance costs elevated. The espionage case is a stark reminder of how fiercely competitors covet TSMC's technological crown jewels.

For now, the company's financial trajectory remains unbroken. First-quarter profit surged 58% to a record high, and management projects full-year revenue growth exceeding 30%. The stock's Tuesday dip looks like a momentary pause in a longer climb — but the threats to TSMC's supremacy are multiplying, and they're coming from all directions.
