Qualcomm FY2025 Overview: A Pivotal Year for AI and Multi-Platform Transformation

In February 2026, Qualcomm released its Fiscal Year 2026 first-quarter results (Q1 FY26), covering the period from September 29, 2025, to December 28, 2025. Since Qualcomm does not publish a standard calendar-year financial report, the following analysis is based on OT’s consolidation of the four quarterly reports from Fiscal Year 2025 (September 30, 2024, to September 28, 2025) .

Viewed through this consolidated perspective, Qualcomm’s 2025 performance may initially appear contradictory—showing both growth and decline. However, a closer examination reveals that it is, in fact, a year marked by accelerated transformation. Total revenue reached $44,284 million (+14% YoY), while gross profit rose to $24,546 million (+12.07% YoY), maintaining a strong gross margin of 55.43%. At the same time, GAAP net income declined sharply by 45% to $5,541 million. While this divergence may suggest weakening fundamentals at first glance, it is better understood as a classic case of accounting distortion rather than operational deterioration.

NXP Q4 2025 Earnings: A Cyclical Recovery Story—and a Strategic Shift Toward the Edge

In early 2026, NXP Semiconductors released its financial results for the fourth quarter and full-year 2025, alongside a comprehensive investor presentation. NXP delivered a scorecard that signals a cyclical bottoming and recovery. More importantly, hidden beneath the financial metrics is a clear message: the company is undergoing a profound structural evolution.

The fourth-quarter performance has already revealed several positive signals. Revenue returned to over $3.3 billion, with both quarter-over-quarter and year-over-year growth turning positive, indicating that demand is at least no longer deteriorating. Even more noteworthy is the cash flow. Non-GAAP free cash flow approached $800 million, accounting for more than 20% of total revenue—a level rarely seen before a full cyclical recovery in the semiconductor industry. To some extent, this demonstrates that NXP is not merely "waiting for the cycle to return," but has found a way to maintain stable output across different economic phases.

This article will guide you through NXP's true strategic layout in the face of the massive AI wave, dissecting it across three dimensions: financial performance, business structure, and long-term strategy.

Beyond the Cycle: Deciphering Infineon’s Zonal Architecture and AI Power Strategy in 2026

On February 4, Infineon released its financial results for the fourth quarter of fiscal year 2025, along with its full-year performance. The results show that, while Infineon maintained relatively stable revenue throughout 2025, profitability remained under pressure due to cyclical softness in key end markets and continued high investment intensity.

Infineon’s business is structured across four main segments—Automotive (ATV), Power & Sensor Systems (PSS), Green Industrial Power (GIP), and Connected Secure Systems (CSS). Among these, Automotive continues to be the primary revenue contributor. However, Power & Sensor Systems (PSS) stands out as a key growth driver, supported by strong demand from AI-related applications and power solutions for data centers.

Beyond the financial overview, this report also provides a deeper look into Infineon’s strategic direction. The company outlines its future vision across several key domains, including Automotive, Electromobility, Software-Defined Vehicles, Green Industrial Power, Power & Sensor Systems, and Connected Secure Systems—highlighting how it is positioning itself for long-term growth at the intersection of electrification and digitalization.

讀《晶片戰爭》 - 「一個可以說No的日本」

《晶片戰爭》作者克里斯・米勒在塔夫茨大學（Tufts University）的弗萊徹學院教授國際史，他也是美國企業研究院（American Enterprise Institute）的Jeane Kirkpatrick客座院士、外交政策研究院（Foreign Policy Research Institute）的歐亞主任，以及總經與地緣政治顧問公司綠罩（Greenmantle）的董事。米勒著有《普丁經濟學》（Putinomics）等書，他也經常為《紐約時報》、《華爾街日報》、《外交事務》、《外交政策》、《美國利益》等媒體撰稿。他於耶魯大學取得歷史學博士學位，於哈佛大學取得歷史學學士學位。米勒特別專長美國與俄國歷史，他在研究冷戰武力競賽的過程中，發現半導體扮演了最關鍵的角色，因此決定以晶片為題展開龐大研究，橫跨三大洲，從台北到莫斯科，採訪上百位晶片業相關科學家、政府官員、工程師、企業家，首次為晶片業的發展提供了難得的歷史縱深。

本書總共可以分成八個部分：

• 第一部  冷戰晶片
• 第二部  美國世界的電路
• 第三部  失去領導地位？
• 第四部  美國的復興
• 第五部  積體電路，整合世界？
• 第六部  創新外移？
• 第七部  中國的挑戰
• 第八部  晶片鎖喉

OT再歸納成三個部分：「始於美國半導體的創新」(原書第一部到第二部)、「日本的挑戰」(原書第三部及第四部的前半)、「晶圓的全球化分工」（原書第四部的後半到第六部）、「中國大陸的挑戰」（原書第一七部及第八部）。本篇文章是閱讀「始於美國半導體的創新」及「日本的挑戰」的摘要，OT覺得「可以說No的日本」很符合「日本第一」的那個年代，所以決定把本篇文章子標題訂為「可以說No的日本」。
