When is the Holtec International IPO date?
Holtec Nuclear Corporation – the legal issuer for the proposed initial public offering (IPO) – publicly filed Form S-1 with the US Securities and Exchange Commission (SEC) on 10 July 2026, following a confidential draft registration process earlier in the year (SEC, 10 July 2026; Reuters, 10 July 2026).
Under the planned reorganisation, Holtec Nuclear would become a holding company controlling Holtec International. It plans to apply to list Class A shares on the Nasdaq Stock Market and Nasdaq Texas under the ticker HNUC (SEC, 10 July 2026).
The IPO date, number of shares and price range have not been announced as of 19 August 2026. Barron's reported in February 2026 that Holtec could be valued above $10bn (Barron's, 9 February 2026), while Renaissance Capital estimated in July 2026 that the IPO could raise around $2bn (Renaissance Capital, 10 July 2026). These figures refer to different measures – estimated company valuation and potential IPO proceeds – and neither is final.
IPO structure and underwriters
Holtec's S-1 sets out a dual-class share structure. Class A shares would carry one vote each, while Class B shares would carry 10 votes each (SEC, 10 July 2026). Founder-affiliated Holtec Holdings is expected to retain voting control following the proposed offering.
The filing names J.P. Morgan, Guggenheim Securities, Goldman Sachs, Citigroup and BofA Securities as joint lead book-running managers. Morgan Stanley, Cantor, BMO Capital Markets and Oppenheimer & Co. are additional joint book-running managers (GlobeNewswire, 10 July 2026).
The exact offer price, share count and proceeds have not been disclosed as of 19 August 2026.
Why now?
Several developments provide context for the proposed IPO:
- Nuclear-sector backdrop: policy support and expectations for higher electricity demand have increased attention on nuclear investment, although projects can involve long development timelines and significant regulatory requirements (Reuters, 10 July 2026).
- Palisades restart: Holtec is working to return the Palisades Nuclear Plant in Michigan to service. If completed, it would be the first US commercial nuclear reactor to restart after permanent shutdown (Reuters, 25 July 2025).
- SMR-300 development: Hyundai E&C is a construction partner for Holtec's planned small modular reactor (SMR) programme, while licensing and construction remain capital-intensive (Renaissance Capital, 10 July 2026).
- Use of proceeds: the S-1 says proceeds will fund the reorganisation and cash distributions. Remaining funds may support general corporate purposes, including SMR-300 licensing, deployment and manufacturing (SEC, 10 July 2026).
Comparisons with peers
NuScale, a US small modular reactor developer, listed in 2022 through a special purpose acquisition company (SPAC) (Reuters, 14 December 2021).
Holtec has a different business mix. It already generates revenue from nuclear equipment and services while developing the SMR-300. However, no SMR-300 unit has yet been built, and the design still requires regulatory approvals (Office for Nuclear Regulation, accessed 19 August 2026).
Nuclear IPO rarity
Holtec would join other recent nuclear-related listings. X-energy (XE) completed its Nasdaq Stock Market IPO in April 2026 (Reuters, 24 April 2026), while Reuters reported that Deep Fission also went public in 2026 (Reuters, 20 May 2026).
Holtec's proposed offering differs in that it combines existing nuclear-services operations with plant-restart and SMR development projects. That gives investors exposure to both established activities and projects that remain subject to execution, funding and regulatory risks.
What is Holtec International?
Holtec International is a nuclear technology and engineering company based in Jupiter, Florida. Its activities include spent-fuel storage, decommissioning, SMR development and engineering services.
Key business segments
- Spent fuel storage – Holtec supplies dry-storage and transport systems for spent nuclear fuel. Its HI-STORM systems are used for storage, while HI-TRAC is a transfer cask (Holtec, acecssed 19 August 2026).
- Decommissioning – through subsidiaries, Holtec provides decommissioning and spent-fuel management services at sites including Oyster Creek, Pilgrim and Indian Point (Holtec, 30 July 2026).
- SMR development – Holtec is developing the SMR-300. The US Nuclear Regulatory Commission (NRC) is reviewing applications for two proposed units, Pioneer One and Pioneer Two, at the Palisades site (American Nuclear Society, 14 January 2026).
- Plant restart – Holtec is working to return Palisades to service. The NRC restored the plant's power-operations licensing basis in August 2025, although it had not resumed power generation as of 19 August 2026 (Holtec, 26 August 2025).
Key milestones in Holtec's history
- 1986: Krishna P. Singh founds Holtec in Mount Laurel, New Jersey.
- 1990s: develops the HI-STORM dry-storage system, which remains part of its spent-fuel business.
- 2000s: expands internationally, including facilities in India and the UK.
- 2018: launches Holtec Decommissioning International (HDI) and expands into nuclear decommissioning.
- 2022: partners with Hyundai E&C to support SMR-300 development.
- 2025: Palisades returns to a power-operations licensing basis, while restart work continues.
- 2026: Holtec Nuclear Corporation publicly files Form S-1 for its proposed HNUC listing on Nasdaq and Nasdaq Texas.
Holtec's key features
- Lifecycle operations. Activities span storage, decommissioning, plant-restart work and SMR development.
- 2025 revenue. Holtec International reported $576.6m, mainly from construction and site services (SEC, 10 July 2026).
- SMR-300 programme. Development continues, with licensing, construction and commercialisation risks (NRC, accessed 19 August 2026).
- Public funding. The US Department of Energy (DOE) closed a $1.52bn loan for the Palisades restart in 2024 (Reuters, 1 October 2024) and selected Holtec Government Services for a $400m SMR award in 2025 (Holtec, 2 December 2025).
Overall, Holtec combines established nuclear-services activities with capital-intensive restart and SMR projects. These different business areas may carry different revenue profiles, timelines and risks.
How does Holtec make money?
Holtec generates revenue from equipment, site services, decommissioning and engineering. Palisades and the SMR-300 could provide additional revenue if the projects progress.
| Revenue stream | Description |
|---|---|
| Spent fuel storage | Sales of storage systems and related site-service contracts. |
| Decommissioning | Decommissioning-site services, including spent-fuel management and related work. |
| SMR deployment | Potential future revenue from SMR-300 licensing, construction and deployment; no unit has yet been built. |
| Plant restart | If restarted, Palisades could generate revenue through long-term electricity sales agreements. Public funding also supports the restart. |
| Global engineering | Engineering and consulting services for international utilities. |
Financials
- Annual revenue: $576.6m in 2025, across construction and site services, decommissioning, and engineering and consulting (SEC, 10 July 2026).
- IPO proceeds: the S-1 says proceeds will fund the reorganisation and cash distributions, while remaining funds may support general corporate purposes, including SMR-300 licensing, deployment and manufacturing (SEC, 10 July).
- Profitability: Holtec reported $386.6m in consolidated net income for 2025, compared with $37.1m in operating income. Realised and unrealised investment gains contributed materially to net income (TradingView, 10 July 2026).
Most 2025 revenue came from construction and site services. Palisades and the SMR-300 could provide future revenue streams, but both carry regulatory, execution and capital risks.
What might influence the Holtec International stock price?
If listed, Holtec Nuclear's share price could respond to company performance, project execution, regulation and broader market conditions.
Macroeconomic and sector trends
Policy decisions and expectations for electricity demand, including demand from data centres, can influence investor sentiment towards nuclear projects (Stockhouse, 22 July 2026).
In the US, the DOE closed a $1.52bn loan for the Palisades restart and selected Holtec Government Services for a $400m SMR award (Holtec, 4 May 2026). The EU taxonomy also includes certain nuclear activities under specified conditions (European Commission, accessed 19 August 2026).
However, nuclear projects can involve long development timelines, substantial capital requirements and regulatory risks. Changes in interest rates, financing conditions or energy policy may also influence project economics and investor sentiment.
Company fundamentals
Investors may assess Holtec's existing nuclear-services revenue alongside progress at Palisades and on the SMR-300.
Delays, cost changes, licensing outcomes, operating performance and the use of IPO proceeds could affect expectations for the business. Positive progress could support sentiment, while setbacks could weigh on it.
Competition and innovation
Holtec identifies NuScale, GE Vernova, Rolls-Royce SMR and other developers as competitors in the SMR market (Fitch Solutions, 5 June 2025).
Holtec's S-1 states that no SMR-300 has yet been constructed or received all necessary regulatory approvals. Licensing progress, project costs, competition and eventual commercialisation could therefore influence investor expectations (SEC, 10 July 2026).
Regulatory and governance
Nuclear projects face extensive regulation, including NRC licensing in the US. Regulatory decisions can affect project schedules, costs and whether proposed facilities move forward.
Holtec Nuclear's proposed dual-class share structure would also give Holtec Holdings voting control after the offering. Investors may consider this when assessing corporate governance and shareholder influence (SEC, 10 July 2026).
ESG considerations
Approaches to nuclear energy within environmental, social and governance (ESG) frameworks vary.
Some investors focus on radioactive-waste management, safety and construction risks. Others consider nuclear energy's relatively low operational carbon emissions and its potential role in electricity systems (European Parliament, accessed 19 August 2026).
These differing views can influence demand for nuclear-related shares.
Market sentiment and trading behaviour
IPO demand, wider equity-market conditions and sentiment towards the nuclear sector could influence Holtec Nuclear's valuation and share-price volatility.
Early trading in newly listed shares can also involve limited price history, changing liquidity and large price movements as investors assess the company.

FAQ
Who owns Holtec International?
Before the proposed IPO reorganisation, Holtec International is held by the Great Banyan Trust and Multi-Decades Trust, both beneficially owned by founder Krishna P. Singh (SEC, 10 July 2026). After the proposed IPO, founder-affiliated Holtec Holdings is expected to retain voting control through its Class B shares (SEC, 10 July 2026).
How much is Holtec worth?
Barron's reported in February 2026 that Holtec could be valued above $10bn (Barron's, 9 February 2026). Separately, Renaissance Capital estimated in July 2026 that the IPO could raise around $2bn (Renaissance Capital, 10 July 2026). The first figure refers to an estimated company valuation, while the second refers to potential IPO proceeds. Neither is final, and the share count and price range remain undisclosed as of 19 August 2026 (TradingView, accessed 19 August 2026).
Is Holtec profitable?
Holtec International reported $576.6m in revenue, $37.1m in operating income and $386.6m in consolidated net income for 2025 (SEC, 10 July 2026). Realised and unrealised investment gains contributed materially to net income, so the net-income figure was substantially higher than operating income.
What is the Palisades restart?
Holtec is working to restart the Palisades Nuclear Plant in Michigan, which closed in 2022 (S&P Global, 20 May 2022). The NRC restored its power-operations licensing basis on 25 August 2025, but the plant did not resume power generation at that point (Holtec, 26 August 2025). As of 19 August 2026, it had not returned to commercial operation and no firm restart date had been announced (American Nuclear Society, 8 July 2026). If completed, it would be the first US commercial nuclear reactor to resume operations following permanent shutdown (Reuters, 25 July 2025).
How does Holtec compare to NuScale?
NuScale is a listed SMR developer, while Holtec combines existing nuclear-services operations with its SMR-300 development programme and the Palisades restart project (SEC, 10 July 2026). The companies therefore differ in their business mix, project pipeline, development stage and capital requirements.
