AMPRIOR, ON / ACCESS Newswire / July 23, 2025 / Plaintree Systems Inc. today announced its intention to initiate an orderly wind-down of the business and operations of its wholly owned subsidiary, Summit Aerospace USA Inc. Following its closure, Plaintree will proceed with the liquidation of Summit's assets.

The primary reason for the decision is due to a material reduction in business from one of Summit's major customers, which business is unlikely to recover. This decision also reflects the Company's ongoing commitment to operational efficiency and strategic alignment. By streamlining its business and focusing on core growth areas, Plaintree aims to position itself for long-term success and value creation for shareholders.

In fiscal 2025, the revenue generated by the Summit Aerospace USA Inc. business was $2,408,450 and represented 10.1% of Plaintree's consolidated revenue and its net loss before income tax and other expenses was $416,058 representing 52.4% of the consolidated net loss before income tax and other expenses. Summit Aerospace USA Inc. represents 11.7% of Plaintree's consolidated total assets.

"This was not a decision we made lightly," said David Watson, CEO of Plaintree Systems. "Summit Aerospace has contributed significantly to our journey, and we are proud of what our U.S. team has accomplished. However, after a careful consideration of the likelihood of future business, the decision is the correct one for Plaintree at this time. By completing this transition, it enables us to reallocate resources and pursue new opportunities for our continuing businesses with greater agility."

It is the current plan to totally cease Summit's operations on or about August 15, 2025. The wind-down and asset liquidation will be conducted in a structured manner to ensure minimal disruption to employees, customers, and stakeholders. Plaintree remains committed to transparency and will provide timely updates as the process unfolds.
