CALGARY, Alberta, Dec. 11, 2025 (GLOBE NEWSWIRE) — DIRTT Environmental Solutions Ltd. (“DIRTT” or the “Company“) (TSX: DRT; OTCQX: DRTTF), a leader in industrialized construction, today announced it has entered into a letter agreement (the “Letter“) with the Business Development Bank of Canada (“BDC“), pursuant to which BDC committed to lending the Company up to C$15.0 million (the “Loan“) subject to the satisfaction of certain conditions.

The Loan matures on April 30, 2032.

The obligations of the Company under the Letter are secured by: (a) a general security agreement from the Company granting (i) a first-ranking security interest in specific equipment and (ii) a security interest in all other present and after-acquired personal property (excluding consumer goods), subject to certain registered charges; (b) a guarantee from DIRTT Environmental Solutions, Inc. for the full amount of the Loan; (c) a landlord’s waivers of distraint; and (d) a first readvanceable mortgage in the principal amount of US$5.0 million on the land and buildings located at 325 North Wells Street, Chicago, IL, USA.

The proceeds of the Loan are expected to be used to partially refinance the Company’s outstanding 6.00% convertible debentures due January 31, 2026 (the “Debentures“). The remaining C$1.6 million principal amount of Debentures is expected to be repaid using cash on hand.
