The engagement related to the same Arizona facility served under the previously announced $3.0 million contract. The new engagement will support additional production capacity at the customer's semiconductor production facility in Arizona.

The award is the latest milestone in HUHUTECH's build-out of HUHU USA, deepening the Company's footprint in Arizona semiconductor corridor and continuing the "Global 2026" strategic initiative of the Company. The contract was signed in May 2026, with all performance, delivery, and revenue recognition expected to be completed within the 2026 fiscal year.

"Every additional order from this anchor customer reflects trust earned through delivery, and this award is exactly the kind of repeat validation we have been building toward," said Mr. Yujun Xiao, Chief Executive Officer of HUHUTECH. "With the U.S. semiconductor capex cycle accelerating around AI, automotive, and high-performance computing demand, HUHU USA is positioned to continue scaling alongside our customers. We are expanding our U.S. team and delivery capacity to support the pipeline of work we see in Arizona."

Under the contract, HUHU USA will deliver high-purity process (HPS) systems integration services, including specialty gas supply system configuration, to support the customer's newly added production lines in Arizona semiconductor industry. The customer's products serve end markets including artificial intelligence and high-performance data centers, premium mobile devices, smart automotive electronics, and high-performance industrial computing applications. The project will be executed independently by HUHU USA's local engineering, technical, and delivery team.

This follow-on engagement extends the relationship established under the previously announced $3.0 million Arizona contract, with both engagements serving the same anchor customer at its Arizona advanced-node foundry. The award validates HUHU USA's long-term investment in U.S. localization, including team build-out, on-the-ground delivery infrastructure, and demostrates the Company's ability to convert initial customer engagements into recurring orders.

As U.S. capital expenditure in advanced-node semiconductor manufacturing continues to grow, HUHU USA expects to continue expanding its U.S. team and delivery capacity to support additional customer growth, capacity-expansion phases, and follow-on engagement opportunities with this and other prospective customers in Arizona.
