AEM Holdings Ltd. (“AEM”), a global leader in test innovation, and ASE Technology Holding Co., Ltd. (“ASE”), the leading provider of semiconductor assembly, testing and materials services, announced a strategic partnership on March 23, 2026, to deliver disruptive test solutions for the rapidly expanding Artificial Intelligence (“AI”) and High-Performance Computing (“HPC”) markets. The collaboration combines AEM’s proprietary test technologies with ASE’s world-class manufacturing scale.
Under the agreement, a wholly owned subsidiary of ASE will subscribe for 3,350,000 ordinary shares of AEM at S$3.591 per share, raising approximately S$12 million in gross proceeds. This represents 1.06% of AEM’s issued share capital as of March 21, 2026. Additionally, the subsidiary will receive 28,111,856 free detachable warrants, divided into two tranches, each subject to revenue-related conditions tied to ASE. If fully exercised, the warrants would represent an additional 8.935% of current issued share capital. The transaction is subject to conditions, including approval from the Singapore Exchange for listing and quotation of the new shares.
Proceeds from the private placement will support AEM’s expansion in Taiwan and the integration of its test technologies—including highly parallel test architectures and advanced thermal management—into ASE’s manufacturing and test environments. The funds will also advance AEM’s product roadmap and accelerate joint go-to-market initiatives for next-generation AI and HPC applications.
The partnership also bolsters ISE Labs, a wholly owned subsidiary of ASE, in expanding AI and HPC processor development capabilities for early-stage testing, validation, and characterization. These efforts target heterogeneous integration architectures, such as multi-chiplet and advanced system-in-package designs, as well as optical interconnect technologies critical for next-generation compute platforms. ASE’s ATM portfolio provides high-volume advanced packaging and test capabilities for production-scale deployment.
“As compute architectures grow more complex and time-to-production continues to compress, test has become a critical enabler of performance, reliability, and manufacturability for next-generation AI and HPC systems,” said Ken Hsiang, Chief Executive Officer of ISE Labs. “By combining ISE’s advanced characterization and production-readiness capabilities with AEM’s scalable, high-parallel test technologies and system-level engineering strengths, this strategic partnership enables rapid transition from validation to ASE’s high-volume deployment while addressing the increasing complexity of advanced compute testing.”
Samer Kabbani, Chief Executive Officer of AEM, commented, “This partnership represents an important step in AEM’s strategy to work closely with industry leaders to advance the state of AI and HPC testing. ASE’s forward-looking approach and global scale make them an ideal partner as test requirements continue to intensify across advanced compute platforms. By combining our respective strengths, we aim to develop and deploy next-generation test solutions that help customers improve performance, scalability, and time-to-market.”
The strategic partnership underscores the growing importance of test innovation in enabling AI and HPC advancements, where complex architectures demand sophisticated testing solutions to ensure performance, reliability, and manufacturability. For more information, visit ASE and NewMediaWire.
