Inspira and Qarakal Sign Joint Development Agreement

Inspira and Qarakal Sign Joint Development Agreement

for Cryogenic Interconnects in Superconducting Quantum Systems

RA'ANANA, Israel, April 30, 2026 - Inspira Technologies OXY B.H.N.

Ltd. (Nasdaq: IINN) ("Inspira" or the "Company") today announced the entry into a Joint Development Agreement

(the "Agreement") with Qarakal Quantum Ltd. ("Qarakal Quantum" or "Qarakal"), a full-stack quantum computing

company developing superconducting quantum computers. The collaboration brings Inspira's Additively Manufactured Electronics (AME) platform,

which operates under the brand name QTREX, into a working superconducting quantum environment to address

one of the field's most persistent scaling challenges: high-performance signal connectivity in cryogenic environments.

The Agreement establishes a structured, multi-phase engineering program

to test and evaluate Inspira's technology under quantum-relevant cryogenic conditions. Qarakal Quantum will provide the technical requirements

for the program, after which the parties will finalize a joint development plan with agreed success metrics, testing scope, timelines,

and resource commitments.

Under the joint development plan, Inspira will provide Qarakal Quantum

with 3D-printed conductive and insulating structures designed to test high-density routing, integrated transitions, embedded shielding

concepts, monolithic rigid-flex structures, and more compact interconnect geometries within constrained cryogenic volumes. Qarakal Quantum

will test and integrate these structures at milli-Kelvin temperatures in its cryogenic development environment and provide engineering

Qarakal's technology reflects a convergence of advanced academic

research, intellectual property and hands-on engineering execution. Qarakal focuses on the design and fabrication of superconducting quantum

processors, along with the development of novel quantum gates and circuits aimed at addressing complex computational challenges beyond

the practical reach of classical systems.

"This Agreement places Inspira's technology in a real-world quantum

development environment, where its performance can be evaluated under relevant cryogenic conditions," said Dagi Ben-Noon, Chief Executive

Officer of Inspira. "This is a structured technical collaboration built around to be agreed upon defined metrics, direct cryogenic

testing, and engineering feedback. This is how real value is built in quantum infrastructure- through measurable execution against one

of the field's most important scaling challenges."

Dr. Nissan Maskil, Chief Executive Officer of Qarakal Quantum, added:

"At Qarakal, our mission is to move quantum computing beyond monolithic lab machines toward modular, deployable, and scalable quantum

infrastructure. A critical bottleneck in this evolution is the cabling density and thermal efficiency required to manage scaling signal

connectivity within the dilution refrigerator."

This collaboration marks a concrete step in Inspira's strategic

expansion into quantum computing and reinforces the Company's focus on addressing one of the field's most important infrastructure

bottlenecks: high-performance connectivity within cryogenic environments for superconducting systems.
