ARENDAL, NO / SHERBROOKE, QC.  15 October 2025 - Tekna (OSE: TEKNA), a
world-leading provider of advanced materials to industry, is proud to announce
that Tekna Advanced Materials inc. has received NADCAP accreditation for
metallic powder manufacturing, making it the first company in the world to
achieve this milestone. The formal audit was completed in August, and the
certificate was officially granted today.

This achievement represents a watershed moment in the standardization and
quality assurance of metallic powder production. Since 2023, Tekna has actively
participated in developing the NADCAP audit criteria (AC7143) for metallic
powder materials and hosted training sessions for auditors at its Canadian
manufacturing facility. The new AC7143 standard is now published and establishes
a global benchmark for quality, traceability, and consistency in powder
manufacturing.

"From day one, we saw this effort not just as an internal quality upgrade, but a
contribution to the aerospace and defense supply chain globally," said Claude
Jean, CEO of Tekna. "By helping to shape the audit criteria, and then
demonstrating compliance through our own processes, we believe we are offering
reassurance to our customers that our powders meet the most rigorous standards
possible."

What Is NADCAP?
NADCAP (National Aerospace and Defense Contractors Accreditation Program) is an
industry-managed global cooperative program overseen by the Performance Review
Institute (PRI). It standardizes audits and accreditation of "critical
processes" (such as heat treatment, chemical processes, non destructive testing)
to ensure suppliers meet the stringent technical and quality requirements
demanded by aerospace and defense OEMs. (p-r-i.org)

Rather than each customer performing their own audit, NADCAP's consensus
approach reduces redundancy, aligns supplier practices with a single credible
benchmark, and drives continuous improvement across the industry. 

Until now, NADCAP had not included a specific accreditation for metallic powder
manufacturing processes. With the release of Audit Criteria AC7143, the industry
now has a dedicated framework for this critical domain.

Our Contribution to AC7143 and the Certification Journey
o	Standards development
From 2023 onward, Tekna was among the leading contributors in industry working
groups and task forces that drafted the AC7143 audit criteria. This effort was a
collaborative initiative involving key aerospace and defense stakeholders
including BAE Systems, GKN Aerospace, Safran, and the Performance Review
Institute (PRI), reflecting a shared commitment to advancing global standards
for metallic powder manufacturing.
These criteria define mandatory practices in areas such as material
traceability, process controls, quality assurance, contamination control,
documentation, and equipment maintenance.
o	Auditor training hosted on-site
To ensure consistent interpretation of the new standard, our Canadian facility
hosted training sessions for NADCAP and OEM auditors. This allowed direct
exposure to real-world metallic powder workflows, improved mutual understanding,
and helped validate the audit checklist in practice.
o	Internal readiness and mock audits
Throughout 2024-2025, our teams ran internal gap analyses, mock audits, and
process refinements to ensure full compliance with AC7143 ahead of the formal
audit.
o	Formal audit and certification
The NADCAP onsite audit was conducted in August. The auditor team thoroughly
examined powder manufacturing facility, procedural controls, documentation,
traceability systems, quality records, and more. With two minor nonconformances
solved, we successfully passed the audit, and the NADCAP certificate was issued
today.

Importance for Aerospace & Defense Customers
Achieving NADCAP accreditation under AC7143 demonstrates that our metallic
powders now adhere to the highest industry standard of quality and traceability.
For aerospace and defense customers, this offers several key benefits:
o	Reduced audit risk: Customers can rely on an independent, standardized
certification rather than conducting custom process audits themselves.
o	Supply chain assurance: It signals that the powder manufacturing process is
robust, traceable, and controlled from raw materials through final inspection.
o	Competitive advantage: As the first NADCAP accredited metallic powder
supplier, Tekna is uniquely positioned to serve defense and space OEMs that
require the highest level of supplier qualification.
o	Continuous improvement: NADCAP's periodic re audits drive ongoing
improvements, keeping our processes aligned with evolving best practices.

About AC7143 - The New Audit Criteria
The new NADCAP Audit Criteria AC7143 define requirements specifically tailored
for metallic powder material manufacturing. These criteria cover:
o	Raw material traceability and certification
o	Powder production process controls (e.g. atomization, classification,
handling)
o	Contamination control and cleanliness protocols
o	Quality assurance testing and documentation (e.g. particle size, composition,
morphology)
o	Change control, calibration, preventive maintenance
o	Audit trail, reporting, and nonconformance management

These criteria have now become the global benchmark for quality in the powder
industry.
