BWXT (BWXT) Q1 2025: Commercial Backlog Surges 78% as Nuclear Demand Accelerates
BWXT’s Q1 saw a decisive step-up in commercial nuclear backlog, reflecting structural demand tailwinds and robust execution across government and medical platforms. Strategic wins in energy security and nuclear medicine, combined with resilient government operations, underscore the company’s “all-weather” positioning. Management’s reaffirmed outlook and commentary on supply chain insulation and long-cycle contracts signal confidence in navigating macro and input cost pressures.
Summary
- Commercial Nuclear Bookings Momentum: Backlog growth signals durable demand and expanding market opportunity.
- Supply Chain Insulation: Domestic sourcing and localized operations reduce cross-border and tariff risks.
- Second-Half Margin Recovery: Temporary cost headwinds expected to abate, supporting full-year outlook.
Performance Analysis
BWXT delivered broad-based growth in Q1, with both government and commercial segments contributing to a double-digit top-line increase. Government operations led with 14% revenue growth, driven by naval propulsion, special materials, and the AOT acquisition, while commercial operations rose 10% on medical and SMR (Small Modular Reactor) activity. Adjusted EBITDA margin in government operations reached its highest level since late 2023, reflecting operational discipline and favorable timing of material procurement under a new pricing agreement for Naval Reactors.
Commercial operations faced a mixed margin picture, with a 100 basis point decline due to unfavorable mix and raw material cost absorption, notably from a zirconium price spike in the CANDU fuel line. However, management expects to contractually recover these costs in the second half, with margins set to rebound as field services and outage schedules normalize. Free cash flow was seasonally soft at $17 million but is expected to accelerate, consistent with historical patterns, as CapEx ramps for the Cambridge expansion and large project backlogs convert to revenue.
- Commercial Backlog Expansion: Segment backlog hit $1.3 billion, up 78% YoY, driven by Pickering Life Extension and SMR wins.
- Government Win Streak: Key contracts in DOE and NNSA reinforce BWXT’s critical role in U.S. energy and defense infrastructure.
- Medical Growth: Double-digit revenue and EBITDA growth in nuclear medicine, with PET diagnostics and radiopharmaceuticals outperforming.
Despite temporary margin pressure in commercial operations, the company’s diversified portfolio and long-cycle contracts underpin a constructive outlook for the remainder of 2025.
Executive Commentary
"Our first quarter financial performance exceeded expectations, highlighted by double digit year over year revenue, adjusted EBITDA, and adjusted earnings per share growth. We had solid execution across our businesses and benefited from an increased pace of work and timing of material procurement."
Rex Jevedin, President and CEO
"Adjusted earnings per share were $0.91, up 20% compared to $0.76 last year due to the operating items previously discussed, complemented by a lower tax rate and slightly lower interest expense that was partially offset by lower pension income."
Rob Lemasters, Executive Vice President and CFO
Strategic Positioning
1. Commercial Nuclear Scale and Visibility
BWXT’s commercial nuclear business is experiencing a step change in demand, as evidenced by a record $1.3 billion backlog. This surge is driven by major wins like the Pickering Life Extension and ongoing SMR projects, positioning BWXT as a critical supplier for both refurbishment and new build opportunities in North America. The Cambridge facility expansion, set to increase capacity by 50%, demonstrates a forward-leaning investment in meeting customer needs and capturing future growth.
2. Government Operations as a Stability Anchor
BWXT’s government segment continues to provide foundational revenue stability, underpinned by its sole-source role in U.S. naval nuclear propulsion and expanding DOE/NNSA relationships. Recent contract wins, including the Strategic Petroleum Reserve management and the DEWS enrichment pilot, reinforce the company’s “all-weather” thesis and broaden its energy security value proposition.
3. Supply Chain Localization and Risk Mitigation
Management emphasized BWXT’s predominantly domestic supply chains, which insulate the business from cross-border disruptions and tariff volatility. In the U.S., supply networks are aligned with national security requirements, while Canadian operations leverage local sourcing for CANDU and SMR projects. This operational design provides resilience amid global commodity and trade uncertainty.
4. Nuclear Medicine and Isotope Pipeline
BWXT Medical posted double-digit growth, driven by PET diagnostics and radiopharmaceutical innovation. The pipeline, including Actinium-225 and the TEC99 program (pending FDA approval), positions the segment to benefit from rising nuclear medicine volumes and the expansion of therapeutic indications, as seen with Novartis’ PluVicto approval.
5. Long-Cycle Contracts and Macro Insulation
BWXT’s business is anchored by long-cycle contracts and customer-funded investments, which provide visibility and buffer against short-term macro volatility. The company’s alignment with secular trends—decarbonization, energy security, and nuclear modernization—supports a multi-year growth runway independent of near-term economic swings.
Key Considerations
The quarter reinforced BWXT’s strategic “all-weather” positioning, with robust bookings, operational wins, and proactive mitigation of supply and cost risks. The company’s diversified exposure across government, commercial power, and medical segments provides multiple avenues for growth and margin expansion.
Key Considerations:
- Commercial Power Demand: Large-scale refurbishments and SMR projects are driving a multi-year backlog build, with organic growth expected to remain in double digits.
- Margin Dynamics: Temporary raw material cost headwinds in commercial operations are set to reverse in the second half as contract recovery mechanisms activate.
- DOE/NNSA Pipeline: Sole-source positioning in enrichment and technical services creates optionality for future contract wins and margin leverage.
- Medical Segment Upside: New radiopharmaceutical approvals and rising scan volumes expand the addressable market for BWXT Medical.
- CapEx and Expansion: Accelerated investment in the Cambridge facility and pending Connectrix acquisition align capacity with visible demand.
Risks
BWXT faces short-term margin pressure from input cost volatility, notably in the CANDU fuel supply chain, though pass-through and contract adjustments are expected to mitigate this by year-end. Execution risk remains in scaling new contracts and integrating acquisitions, while regulatory delays in medical product approvals could defer revenue realization. Macro shocks or shifts in government nuclear policy could impact long-cycle project timing, though current secular trends and bipartisan support for nuclear remain favorable.
Forward Outlook
For Q2, BWXT guided to:
- Lower earnings due to normalization of material procurement timing in government operations and ongoing commercial margin headwinds.
- Continued backlog conversion with ramping CapEx to support expansion projects.
For full-year 2025, management reaffirmed guidance:
- Revenue, adjusted EBITDA, EPS, and free cash flow all maintained within prior ranges.
Management highlighted several factors that will shape the year:
- Second half expected to deliver over half of full-year EPS as margins recover and CapEx accelerates.
- Commercial operations to benefit from cost recovery and steady backlog execution.
