Recommendation

The filing shows strong Q1 results and affirmed guidance, which is positive. However, the slight decrease in nuclear capacity factor and the EFOF for gas/oil/hydro fleets, along with the inherent risks in forward-looking statements, suggest a 'hold' recommendation pending further market developments and sustained performance.
