Cameco’s Westinghouse Stake Could Be Worth More Than $24.5 Billion
Cameco (CCO) shares rose 3.6% on reports that its co-owned Westinghouse is targeting a $50B US IPO, potentially valuing Cameco's 49% stake at over $24.5B. Cameco's Q2 earnings showed a Westinghouse net loss, but the company attributes this to project-related revenue fluctuations. Westinghouse's adjusted EBITDA fell to C$163M in Q2 from C$352M a year earlier. Cameco's P/E ratio has not significantly re-rated following the IPO news, with estimates ranging from $15B to $50B for Westinghouse.
