Proposed Acquisition Expected to Strengthen Sovereign Manufacturing Capability and Provide Immediate Revenue and EBITDA Contribution

Vancouver, BC – TheNewswire - June 1, 2026 – Critical Infrastructure Technologies Ltd. (CSE: CTTT) (OTC: CITLF) (FRA: X9V) (“ CiTech ” or the “ Company ”), a leading developer of autonomous, high-capacity mobile communications and security platforms, further to its press releases dated October 21, 2025, December 11, 2025, January 22, 2026, March 11, 2026, April 14, 2026 and May 13, 2026, is pleased to provide an update on its proposed acquisition to acquire 100% of the issued shares of a Western Australian precision engineering and manufacturing company with strong connections to the defence and mining sectors (the “ Acquisition ”).

Strategic Benefits

The proposed Acquisition is expected to provide CiTech with:

• Immediate sovereign manufacturing capability in Western Australia  

• Vertical integration of fabrication and engineering operations  

• Faster prototyping, production, and deployment of Nexus platforms  

• Access to a highly skilled workforce and advanced fabrication infrastructure  

• Enhanced capability to support defence, mining and critical infrastructure customers  

This strengthened manufacturing capability is expected to allow CiTech to accelerate production of its Nexus autonomous communications platforms, supporting increasing demand from international defence, mining and infrastructure markets.

Executive Commentary

Brenton Scott, Chief Executive Officer of CiTech, said receiving debt approval and launching the previously announced LIFE offering for gross proceeds of up to approximately $3 million (the “ LIFE Offering ”) are significant milestones in finalising the Acquisition.

“Being able to settle the Acquisition represents a significant step in CiTech’s growth strategy. This Acquisition is expected to provide immediate revenue and earnings while delivering the manufacturing capability required to scale production of our Nexus platforms and support increasing international demand.

Importantly, it is poised to strength our sovereign Australian defence manufacturing capability with local and international defence primes and position CiTech to participate in major allied supply chains.”

Integration & Timeline

The Acquisition remains subject only to:

• Closing of the LIFE Offering  

• Satisfying the debt facility conditions and executing documents  

• Standard closing conditions  

Completion of the Acquisition is expected to occur in June 2026.
