MDA's $100M IRIS² antenna deal: 2.5% of backlog, 20% of the satellites

Updated 30 Oct 2026 from live prices and SEC filings

MDA Space will supply digital antennas for the first 66 IRIS² satellites under a deal worth more than $100M with Thales Alenia Space. That is only about 2.5% of its $4.0bn backlog, but it covers just 66 of the 330 low orbit satellites and gives its AURORA antenna a European customer.

What happened

On 30 October 2026, before the US market opened, MDA Space said it had signed an authorisation to proceed (ATP) agreement with Thales Alenia Space, the Thales and Leonardo joint venture, to start work on its AURORA digital phased array antennas and digital antenna controller for the 66 "Layer 1" satellites of IRIS², the EU's secure connectivity constellation. The ATP is valued at more than $100 million.

MDA said the hardware will be designed, built and tested at its Montréal facility, the satellites are due to launch in 2029, the ATP will enter its backlog in the fourth quarter of 2026, and the definitive contract for its full scope of work still has to be finalised. MDA's New York listed shares closed at $29.12 on 29 October, before the news, down 0.6% on the day and about 41% below their 52-week high of $49.37.

Orbit Alpha view: small in dollars, bigger for AURORA

Measured against MDA's own numbers, the order is modest. More than $100 million is about 2.5% of the $4.0 billion backlog MDA reported at 30 June, and about 5.4% of the midpoint of its 2026 revenue guidance of $1.8 billion to $1.9 billion (our calculation; MDA reports in Canadian dollars and the release does not name a currency, so we compare in the dollars it uses). In the second quarter alone MDA booked about $809 million of new work, so this ATP is roughly one eighth of a single quarter's orders.

Measure	Figure	Our calculation
ATP value	more than $100M	starting value, not the full contract
Backlog at 30 June 2026	$4.0bn	ATP is about 2.5%
2026 revenue guidance midpoint	$1.85bn	ATP is about 5.4%
Q2 2026 net bookings	about $809M	ATP is about 12%
Value per Layer 1 satellite	more than about $1.5M	$100M spread over 66 satellites
IRIS² low orbit satellites covered	66 of 330	20%; the 264 Layer 2 satellites are not part of this ATP

The more useful point is what the order changes in MDA's mix. Satellite Systems produced $649.2 million of MDA's $962.7 million revenue in the first half of 2026, about 67%, and MDA said that segment's growth was driven primarily by the Telesat Lightspeed programme. IRIS² puts AURORA on a second low orbit constellation, run by a different customer and funded by a different government, which matters for a company whose largest growth driver is a single programme.

Two details keep this in proportion. First, an ATP is permission to start work, not the final contract: the value can grow when the definitive contract is signed, but the release gives no figure for the full scope. Second, Thales Alenia Space is also responsible for the governmental payloads on the 264 Layer 2 satellites, four times as many as Layer 1, and nothing in the release says MDA has been chosen for those. The scale of the opportunity therefore depends on work MDA has not yet won.

So the order adds little to MDA's numbers today. What it shows is that a Canadian supplier has been given a role building hardware for a programme Europe describes as sovereign, which is a commercial reference for AURORA beyond its home market.

Why MDA wanted it

MDA has been building AURORA as a production-line product for constellations rather than a one-off payload, and said the system is engineered for high-volume production. A 66-satellite order is the kind of volume that design is meant for. The release also frames the deal as part of MDA's push into sovereign and defence programmes, the same theme its second quarter results highlighted with wins for the Canadian Space Agency, Japan's Ministry of Defense and the European Space Agency.

What it means for other space stocks

Eutelsat leads the IRIS² low orbit segment and booked €8.9 billion of IRIS² construction work this week. As we noted in our analysis of that order book, much of that money is likely to pass through to the companies building the satellites. MDA's deal is an early example of that money reaching suppliers.
Telesat remains MDA's main constellation customer through Lightspeed. A second large constellation customer means MDA's satellite business depends a little less on one programme's timetable.

What to watch next

5 November 2026: MDA's third quarter results. The ATP will not be in the 30 September backlog, since MDA says it will be booked in the fourth quarter, so watch for comments on the definitive contract and its value.
The definitive contract with Thales Alenia Space, which will show how much larger than $100 million MDA's full scope is.
Any supplier choices for the 264 IRIS² Layer 2 satellites, where Thales Alenia Space provides the governmental payloads.
The 2029 launch date for the first 66 Layer 1 satellites, which sets the deadline for MDA's deliveries.

Questions and answers

How big is MDA's IRIS² contract?

The authorisation to proceed is worth more than $100 million, about 2.5% of MDA's $4.0 billion backlog at 30 June 2026 and about 5.4% of the midpoint of its 2026 revenue guidance, on our calculation. The definitive contract has not yet been signed.

Which IRIS² satellites does MDA's deal cover?

The 66 Ka-band Layer 1 satellites in low Earth orbit, due to launch in 2029. That is 20% of the 330 low orbit satellites planned; the 264 Layer 2 satellites are not part of this agreement.

When will the contract show up in MDA's results?

MDA says the ATP will be added to backlog in the fourth quarter of 2026, so it will not appear in the third quarter figures due on 5 November 2026.
