Artisan Mid Cap Fund stated the following regarding BWX Technologies, Inc. (NYSE:BWXT) in its second quarter 2025 investor letter:

"During the quarter, we initiated new GardenSM positions in RBC Bearings, BWX Technologies, Inc. (NYSE:BWXT) and Duolingo. BWX Technologies designs and manufactures nuclear reactor vessels and components for the US Navy and commercial markets. It has the only Nuclear Regulatory Commission Category 1-licensed facilities permitted to handle, store and process highly enriched uranium in the US. This exclusivity gives it a dominant position across both business segments. It maintains a monopoly on nuclear reactors and fuel for US submarines and aircraft carriers, and it offers a differentiated portfolio of heavy nuclear components. The build schedule for US Navy submarines and aircraft carriers provides long-term visible growth, which we expect to be enhanced by upcoming investments by Canada into refurbishing, expanding and building nuclear power plants. In addition, the Trump administration’s stated desire to accelerate US nuclear energy development could become a catalyst for growth."
