A potential all stock merger between SpaceX and Tesla into a roughly US$3.5t AI group has grabbed Wall Street’s attention, because it could reshape everything from index weightings to how defense, aerospace and satellite companies are valued next to this proposed giant. Investors who ignore it risk missing where capital may cluster next. This article breaks down 3 stocks exposed to that news and what that might mean for your portfolio decisions.
The three stocks covered below are just a starting sample, since the full screen surfaced 42 more listed defense, aerospace and satellite contractors with equally compelling narratives that are not broken down in this article. If you want to identify your own high-conviction ideas off the back of this theme, head straight into the Listed Defense, Aerospace & Satellite Contractors screener to analyze, sort and focus on the contractors that best fit your view.
Viavi Solutions (VIAV)
Overview: Viavi Solutions provides test, monitoring, and optical technologies for secure military, aerospace, and critical communications networks worldwide, linking directly to defense and satellite mission support.
Operations: Viavi generates about US$1.2b from Network and Service Enablement and US$335 million from Optical Security and Performance Products, with revenue diversified across the United States, Greater China, EMEA and wider Asia-Pacific.
Market Cap: US$8.6b
Viavi Solutions matters for this defense, aerospace and satellite screen because its test gear and optical security products help keep mission-critical communications reliable and secure as networks get faster and more complex.
"Viavi is experiencing robust and sustained demand across the data center ecosystem, with customers updating optical connectivity to 400G, 800G, and now 1.6T, enabling multi-year upgrade cycles and expanding its total addressable market, which should drive structural revenue growth through 2026 and beyond."
The real swing factor is how one emerging defense-focused demand stream ultimately feeds through to pricing power and long-run profitability.
That pricing power question is exactly what the full narrative for Viavi Solutions unpacks, including where accelerating defense demand could be masking bigger risks or upside.
Sanmina (SANM)
Overview: Sanmina provides integrated manufacturing, design, components, logistics, and after-market services for OEMs across industrial, medical, defense, aerospace, automotive, communications, and cloud markets.
Operations: Sanmina generates about US$11.0b from Integrated Manufacturing Solutions and US$1.9b from Components, Products and Services, with sales spread across the United States, Mexico, APAC and EMEA.
Market Cap: US$9.1b
Sanmina matters in this defense and aerospace screen because its electronics manufacturing and after-market services plug directly into mission-critical programs for large OEM contractors. Its AI and cloud work can also intersect with data-heavy military and satellite applications.
"The integration of ZT Systems into Sanmina is now contributing several billions of dollars of annualized revenue, and management continues to point to a path toward at least US$16b of revenue in fiscal 2027."
What really matters for investors is how one unseen pressure could shape margins if AI-heavy demand stops running at full speed.
If that pressure point is what you care about, the full narrative for Sanmina explains how accelerating AI demand, contract mix and capital intensity could still reshape Sanmina’s long term earnings profile.
MDA Space (TSX:MDA)
Overview: MDA Space builds satellites, robotics and Earth observation systems that support defense, communications and government space programs worldwide.
Operations: MDA Space generates CA$1.87b from Geointelligence, Robotics & Space Operations and Satellite System, with revenue concentrated in Canada and the United States.
Market Cap: CA$6.3b
MDA Space gives you direct exposure to the defense and satellite connectivity theme, since its hardware and services underpin broadband, surveillance and exploration projects that major governments and commercial operators are racing to scale.
"The ramp-up of large LEO constellation contracts, including the landmark $1.8 billion EchoStar direct-to-device satellite order with options to expand, and multiple pipeline opportunities in broadband, defense, and IoT, is expected to drive robust multi-year revenue growth as global demand for satellite connectivity accelerates."
What really matters now is how one unresolved cost and funding balance ultimately shapes profitability as that contract pipeline turns into delivered hardware.
That funding balance is exactly what the full narrative for MDA Space unpacks. It reveals how accelerating constellation demand, contract structure and capital needs could reshape MDA Space’s risk and upside profile.
