Defence Holdings Agrees Appointment of Chief Executive Officer

 

Defence Holdings PLC (LSE: ALRT), the UK-listed defence technology group, is
pleased to confirm that it has agreed the appointment of a Chief Executive
Officer, following the conclusion of a comprehensive and highly targeted
appointment process.

 

As referenced in the Company's recent Operational Update, the Board had
progressed to the advanced stages of a Chief Executive Officer appointment
process, with a further update expected in January. The Board is pleased to
confirm that the process has now concluded and that agreement has been reached
ahead of that anticipated timeframe.

 

The new Chief Executive Officer is expected to formally move into the role in
early Q2, following completion of contractual arrangements and notice period
obligations associated with the appointee's current position. The Company will
provide a further update once these matters are finalised.

 

Strategic and Commercial Context

 

The agreement represents a key milestone as Defence Holdings transitions from
capability development into sustained delivery and commercial execution across
its sovereign-AI and mission-critical defence software programmes.

 

The individual selected brings senior executive leadership experience across
defence, national security and government-aligned technology environments,
alongside a proven commercial and operational track record. Their background
includes leadership of organisations operating at scale, responsibility for
significant revenue growth and P&L performance, execution of complex
fundraising and capital strategies, and experience across mergers,
acquisitions and business transformation.

 

The appointee has also led large, multi-disciplinary teams delivering complex
technology and infrastructure programmes within highly regulated and
security-sensitive frameworks, working closely with senior government, defence
and national-level stakeholders.

 

This combination of defence credibility, commercial execution and delivery
leadership materially strengthens Defence Holdings' executive capability and
provides the leadership required for the Company's next phase of delivery and
scale.

 

Board Comment

 

Andy McCartney, Chief Technology Officer of Defence Holdings, commented:

 

"Following an extensive and highly competitive search, during which we
considered a number of high-calibre candidates from across defence, national
security and mission-critical technology, the Board is delighted to have
reached agreement on this appointment.

 

This individual brings deep experience leading complex, defence-aligned
organisations through delivery and scale, and we very much look forward to
working with him as he joins the Company and leads the next phase of
execution."

 

Next Steps

 

Further details regarding the appointment, including background and
professional history, will be announced in due course once contractual and
disclosure restrictions have been lifted. The appointment remains subject to
the completion of customary regulatory and background checks.

 

With agreement reached on the appointment of a Chief Executive Officer,
Defence Holdings is well positioned to further strengthen programme execution
and organisational readiness as its sovereign-AI capabilities progress toward
operational deployment in support of UK and allied defence requirements.
