NEWS RELEASE
NOT FOR DISTRIBUTION TO U.S. NEWSWIRE
SERVICES OR FOR DISSEMINATION IN THE UNITED STATES
MDA SPACE ANNOUNCES
OFFERING OF C$600 MILLION SENIOR UNSECURED NOTES DUE 2033
JULY 23, 2026
(TORONTO, ON) – MDA Space Ltd. (“MDA Space” or the “Company”) (TSX:MDA) (NYSE:MDA),
a trusted mission partner to the rapidly expanding global space industry, announced today that it has priced a private placement offering
(the “Offering”) to sell, pursuant to the Offering, C$600 million aggregate principal amount of 6.50% senior
unsecured notes due August 5, 2033 (the “Notes”). The Offering is expected to close on or about August 5,
2026, subject to customary closing conditions.
The Notes will
be issued at a price of C$1,000 per C$1,000 principal amount of Notes. The Notes will constitute senior unsecured obligations of the
Company, ranking pari passu in right of payment with all existing and future senior unsecured indebtedness of the Company (including
the 7.00% senior unsecured notes issued by the Company on December 23, 2025 in an aggregate principal amount of C$250,000,000 due
December 23, 2030), and will be guaranteed by certain of the Company’s subsidiaries. Interest on the Notes will accrue at
a rate of 6.50% per annum, payable semi-annually in arrears on February 5 and August 5 of each year, commencing on February 5,
2027.
The Company intends
to use the net proceeds from the Offering to fund a portion of the purchase price for the acquisition of Blue Canyon Technologies LLC
(“BCT”) (the “Acquisition”), that was previously announced by the Company on June 19, 2026,
and acquisition-related fees and expenses. Once completed, the Acquisition is expected to provide MDA Space with a strategic business
and manufacturing footprint to capitalize on growing demand in the U.S. government market for defence space missions. The Acquisition
is expected to close by the end of 2026, subject to customary closing conditions. In the event the Acquisition does not close, the Company
will be required to redeem all of the outstanding Notes at a redemption price equal to 100% of the principal amount thereof, plus accrued
and unpaid interest.
“This successful
offering supports the long-term growth objectives underlying our acquisition of BCT, and our steadfast commitment to create shareholder
value,” said Guillaume Lavoie, Chief Financial Officer of MDA Space. “We are pleased with the market’s positive response
and strong demand to participate in the offering, which reflects continued investor confidence in our ability to execute on our growth
strategy while maintaining balance sheet discipline.”
The Notes are being
offered through a syndicate of underwriters led by RBC Capital Markets, BMO Capital Markets and Scotiabank.
The Notes are being
offered for sale in each of the provinces of Canada to “accredited investors” on a private placement basis, in reliance upon
exemptions from the prospectus requirements under applicable Canadian securities laws. The Notes have not been registered under the United
States Securities Act of 1933, as amended (the “U.S. Securities Act”) or any state securities laws and are being offered
and sold in the United States only to qualified institutional buyers, pursuant to Rule 144A of the U.S. Securities Act, and
outside the United States in offshore transactions in reliance upon Regulation S under the U.S. Securities Act.

This news release
shall not constitute an offer to sell or the solicitation of an offer to buy the Notes, nor shall there be any offer or sale of the Notes
in any jurisdiction in which such offer, solicitation or sale would be unlawful.
