London, December 15, 2025 — The UK Government has issued a final order allowing Quantum Design Oxford UK Limited to acquire full ownership of Oxford Nanoscience Limited, subject to binding conditions aimed at safeguarding national security interests.
Following an in-depth national security assessment, the Chancellor of the Duchy of Lancaster made the final order under section 26 of the National Security and Investment Act 2021. The order takes effect on completion of the transaction.
Transaction Structure
Under the deal, QD Oxford UK Limited will acquire 100 percent of the issued share capital of Oxford Nanoscience Limited, thereby gaining control of the company. The parties subject to the order are Oxford Nanoscience Limited, QD Oxford UK Limited, and Quantum Design International Incorporated.
The Government concluded that the acquisition constitutes trigger events under sections 8(2)(c), 8(5)(c) and 8(6) of the Act.
Conditions Imposed
The Chancellor allowed the transaction to proceed on the condition that the parties maintain Oxford Nanoscience’s capability within the UK to develop and manufacture dilution refrigerator products and services used in quantum technologies. These capabilities must be sufficient to meet demand arising from UK Government projects and programmes.
In addition, the parties are required to ensure continuity of supply and servicing of dilution refrigerators for current and future UK Government quantum technology projects, subject to funding and on reasonable commercial terms.
National Security Assessment
According to the Government, the measures set out in the final order are necessary and proportionate to prevent or mitigate risks linked to the UK’s continued access to dilution refrigerators, which enable quantum technologies with national security applications.
