The Situation Explained:
🧐 The Main Issue: TSMC allegedly produced approximately three million chips designed by the Chinese firm Sophgo, which subsequently found their way into Huawei’s Ascend 910B AI system. Because TSMC's manufacturing equipment incorporates U.S. technology, these chips fall under strict American export control rules.
🔍 Discovery and Investigation: TechInsights, a Canadian research organization, uncovered a TSMC-produced chip inside Huawei’s AI accelerators, prompting the ongoing investigation by U.S. authorities.
💸 Significant Financial Impact: Under U.S. export control laws, TSMC may face penalties of up to twice the value of the violating transactions. Lennart Heim of the RAND Corporation estimates the fine could surpass $1 billion.
🚫 Immediate Actions Taken: In response, in early 2025, TSMC halted all shipments to Sophgo, and the U.S. Commerce Department mandated that TSMC stop exporting any 7nm or more advanced chips to China intended for AI applications.
📌 Trade Restrictions Expanded: After the investigation began, Sophgo joined Huawei on the U.S. restricted trade list in January, tightening trade limitations even further.
🌏 Broader Implications: The timing of this issue is sensitive, coinciding with increasing U.S.-Taiwan trade tensions and new tariffs. Although semiconductors are not currently impacted, TSMC’s expansive $100 billion investment plan in the U.S.—including five new fabs—adds complexity to the geopolitical backdrop.
💼 Financially Prepared: TSMC’s strong cash position, exceeding $70 billion in reserves and short-term investments, should enable the company to manage this financial blow.
Why AI/Semiconductor Investors Should Care: This incident highlights how strictly the U.S. is enforcing advanced chip export regulations, particularly when Huawei is involved. Investors should closely monitor how TSMC strengthens its compliance strategies and adjusts its supply chain. Continued strict enforcement could reshape global semiconductor dynamics, potentially impacting TSMC’s strategic choices despite its financial resilience.

[Paid Subscribers] Aehr Test Systems Sees Revenue Growth and Expands Beyond Silicon Carbide
Date of Event: April 8, 2025 – Q3 2025 Earnings Conference
Executive Summary
*Reminder: We do not talk about valuations, just an analysis of the earnings/conferences
Aehr Test Systems, Inc. (“Aehr”) reported its fiscal third-quarter (Q3) 2025 earnings on April 8, 2025, highlighting year-over-year revenue growth, robust bookings, and a diversifying customer base. Traditionally known for its wafer-level burn-in (WLBI) solutions for silicon carbide (SiC) devices, Aehr is expanding into newer, high-growth segments such as artificial intelligence (AI) processors, gallium nitride (GaN) power semiconductors, data storage applications, and silicon photonics.
In Q3 2025, Aehr’s net revenue rose to $18.3 million, up from $7.6 million in Q3 2024. Non-GAAP net income reached $2.0 million, or $0.07 per diluted share—an improvement from a loss of $(0.9) million in the same period last year. Management attributed this performance to broader end-market penetration and early successes in AI processor burn-in, an area gaining momentum amid rising demand for data center acceleration solutions.
Notably, Aehr has diversified its revenue profile: whereas silicon carbide accounted for more than 90% of revenue in fiscal 2024, it contributed less than 40% in Q3 2025. Meanwhile, AI processors represented more than 35% of the company’s Q3 revenue. The quarter also included new multi-wafer test systems orders for gallium nitride and the first high-volume order for Aehr’s new application in hard disk drive components.
Despite these positive developments, Aehr Test Systems has withdrawn its formal revenue guidance for the remainder of fiscal 2025, citing near-term uncertainty from newly announced tariffs. Nonetheless, the company remains optimistic about long-term trends across AI, wide bandgap semiconductors (both SiC and GaN), emerging flash memory technologies, and silicon photonics.
Below is a concise overview of Aehr’s Q3 financial performance, commentary on growth opportunities, product and technology differentiators, headwinds, a financial deep dive, and the strategic outlook shared by management.
Growth Opportunities
Aehr Test Systems began as a key supplier of burn-in and test equipment for SiC power semiconductors, finding a natural market fit in automotive electrification. However, fiscal 2025 has marked a deliberate push into more diverse markets. According to management, such a pivot stems from:
