New York Space Tech Stocks Lose $550 Billion in a Day: Growth Stock Fatigue?

MDA Space Ltd. (NYSE: MDA) tumbled 6.9% to close at $45.33 on the New York Stock Exchange. Its market capitalization shrank to about $6.29 billion, erasing roughly $400 million in value in a single day—equivalent to around ₩550 billion. Trading volume exceeded one million shares, amplifying the stock’s volatility.

In its recently released first-quarter results, MDA Space reported revenue of CAD 461.0 million, a 32% increase year-over-year, but net income declined 10% due to intangible-asset amortization charges related to acquisitions. Even after raising approximately $300 million through its March NYSE listing, the company has maintained its 2026 guidance of $1.7–1.9 billion in revenue and $320–370 million in adjusted EBITDA, continuing an aggressive growth trajectory.

Headquartered in Brampton, Canada, MDA Space is a leading commercial space-infrastructure company with more than 55 years of experience and participation in over 450 space missions, focusing on satellite systems, space robotics, and geospatial information services. Although traditionally known for projects such as Canadarm and RADARSAT—and dual-listed on the Toronto and New York exchanges—the company is now positioning low-Earth-orbit satellite constellations and expanding defense-space requirements as its next engines of growth.
