J.P. Morgan launched coverage on two IPOs with Strong Buy ratings. X-Energy's pebble-bed reactor design earns an edge in the nuclear power race. Here is what would confirm or break the setup.
Two newly public companies earned 'Strong Buy' ratings from J.P. Morgan as 2026 opens with a favorable backdrop for initial public offerings. The investment bank's top picks come as markets stabilize and capital costs decline, setting up a potential breakout year for new listings.
The first pick is X-Energy Reactor Company (XER) , a nuclear reactor designer focused on a specific high-temperature gas-cooled helium cycle reactor. The Xe-100 is built with a pebble-bed architecture, a design that J.P. Morgan sees as differentiated in the emerging market for advanced nuclear power. The bank's analysts believe X-Energy's technical approach positions it well against competitors pursuing other reactor types, though execution risk remains high for a company at this early stage of commercialization.
The simple read is that new nuclear IPOs benefit from an energy transition narrative. Investors see growing demand for clean baseload power from data centers and manufacturing reshoring, and assume every advanced reactor company will capture a share. That framing ignores a crucial distinction: licensing timelines, fuel supply, and construction costs vary dramatically by technology type.
The better read requires examining X-Energy's specific advantages within that landscape. The Xe-100's helium cycle avoids water cooling, a major source of operational complexity in traditional reactors. The pebble-bed design means the reactor can run at higher temperatures with lower pressure, theoretically improving safety margins and reducing containment costs. These engineering differences matter more than the broad nuclear narrative when evaluating whether the company can actually deliver on its project pipeline.
For J.P. Morgan's thesis to hold, X-Energy must move through Nuclear Regulatory Commission licensing stages on schedule. Each phase of design certification, construction permit, and operating license creates binary risk. A delay at any stage would compress the timeline for revenue generation, making the current valuation harder to justify.
The primary invalidation risk is first-mover disadvantage on fuel supply. The Xe-100 uses TRISO particle fuel, which has limited production capacity globally. If fuel suppliers prioritize competing reactor designs or face their own production bottlenecks, X-Energy's deployment timeline could slip regardless of regulatory progress.
J.P. Morgan's second top pick also operates in a capital-intensive sector where patience is required. For both names, the bank's conviction rating reflects a view that stable markets and lower borrowing costs create a multi-quarter window for these companies to execute their business plans without being pressured by adverse macro conditions.
The next decision point for X-Energy investors is the company's first quarterly report as a public entity. That filing will show cash burn rate, backlog conversion, and any updates on regulatory milestones. A reported progress on a license application or fuel supply agreement would add weight to J.P. Morgan's bullish case. A miss on any of those fronts would make the 'Strong Buy' rating harder to sustain.
