Uranium Leader Sees Market Cap Surge of 6 Trillion Won in One Day... Is Nuclear Energy Buzz Reignited?

Cameco Corp. (CCJ), a leading uranium producer, surged 8.42% on the New York Stock Exchange to close at $126.43 (approximately KRW 170,000). Trading volume reached 1.934 million shares, and its market capitalization rose by about $5 billion (roughly KRW 6.8 trillion) in one day, bringing the total to around $55 billion (approximately KRW 74 trillion).

Although the previous session saw a decline of over 5%, underperforming the broader market, the stock has only endured a single-digit pullback from its all-time high set at the end of January and continues to trade near that level. In February, Cameco signed a long-term uranium supply agreement worth about $2.6 billion with India and provided earnings guidance tied to new U.S. nuclear projects with Westinghouse, reinforcing its medium- to long-term growth narrative.

Headquartered in Saskatoon, Canada, Cameco is one of the world’s largest uranium producers and nuclear fuel services companies. It operates high-grade, low-cost uranium mines as well as refining, conversion and fuel services facilities across Canada, the U.S., Kazakhstan and other countries, accounting for a double-digit share of global uranium supply. Since its 1988 formation through the merger of Canadian government-owned uranium companies, Cameco has expanded throughout the entire nuclear fuel cycle—from uranium mining to fuel bundle manufacturing—and, via equity investments in Westinghouse, is widely regarded as a key beneficiary of the “nuclear renaissance.”
