Tortoise Capital Launches the Actively Managed Tortoise Nuclear Renaissance ETF (TNUK), Offering Investors the Chance to Benefit from the Accelerating Nuclear Renaissance

OVERLAND PARK, Kan.--(BUSINESS WIRE)-- Tortoise Capital Advisors, L.L.C. (Tortoise Capital), a fund manager focused on energy and infrastructure investing, is today unveiling the newest addition to its growing lineup of Exchange Traded Funds (ETFs) with the launch of the Tortoise Nuclear Renaissance ETF (NYSE ARCA: TNUK), an actively managed fund designed to capture the full scope of the global nuclear ecosystem at a time when demand for reliable, around-the-clock power is reaching record levels.

TNUK invests in companies across the $1.7 trillion nuclear value chain – uranium mining, conversion and enrichment, fuel services, original equipment manufacturers (OEMs), small modular reactor (SMR) developers, and operators – as governments, utilities, and data-center developers are committing capital to nuclear activity.

“The nuclear cycle is underway,” said Matt Sallee, Head of Investments, with Tortoise Capital. “AI demand continues to surge, multiple U.S. reactors are restarting or extending their operational lifespans for 20 to 40 years, utilities are locking in long-term uranium contracts at the fastest pace in a decade, and the U.S. is reshoring the entire fuel cycle with tens of billions in federal support. TNUK is built to give investors pure-play exposure to this structural shift as nuclear transforms from a legacy asset to a critical infrastructure growth story.”

Positioning investors to benefit from one of the most compelling long-term energy themes of the next decade, TNUK’s launch arrives as the narrative around nuclear energy switches from policy debate to execution.

“You can feel the tone shift across the industry,” said Mark Marifian, Head of Product at Tortoise Capital. “Nuclear has moved from a long-term idea to a near-term solution, with even previously mothballed plants coming back into service to meet rising power demand. As AI and electrification accelerate, investors need an active manager with real energy expertise to navigate the opportunities emerging across the nuclear value chain. This ETF expands our electrification-infrastructure suite at exactly the right moment.”

TNUK is deliberately broader than existing uranium-focused funds, offering investors balanced exposure to the companies enabling the full nuclear buildout.

“While TNUK offers exposure to uranium miners, we think the bigger story is the ecosystem around them,” said Rob Thummel, Senior Portfolio Manager of Tortoise Capital. “The engineers, OEMs, reactor vendors, operators, and safety equipment providers are all businesses that are seeing real growth. With these tailwinds, we wanted an ETF that reflected the opportunity of the full value chain rather than leaning on just one part.”

Backed by a seasoned energy investment team with a track record of 20+ years managing complex, regulated sectors through multiple market cycles, TNUK will utilize the same focused, research-driven approach that underpins Tortoise’s existing energy and infrastructure ETFs.

“TNUK fits naturally into our ETF lineup because it expands on what we’ve always aimed to do which is give investors access to energy and infrastructure themes that are essential to our way of life,” added Tom Florence, Chairman and CEO of Tortoise Capital. “Nuclear is becoming an integral part of that story, and we think this actively managed fund offers a unique way for investors to incorporate this renaissance into their energy framework.”

Before investing in the funds, investors should consider their investment goals, time horizons and risk tolerance. The funds’ investment objective, risks, charges and expenses must be considered carefully before investing. The statutory prospectuses and the summary prospectuses (click here) contain this and other important information about the funds. Copies of the funds’ prospectus may be obtained by calling 855-994-4437 or by emailing info@tortoisecapital.com. Read it carefully before investing.

As stated in the Prospectus, the total annual operating expenses are 0.75%. The adviser has agreed to pay all expenses incurred by the fund except for the advisory fee, interest, taxes, brokerage expenses and other fees, charges, taxes, levies or expenses (such as stamp taxes) incurred in connection with the execution of portfolio transactions or in connection with creation and redemption transactions.

Investing involves risk. Principal loss is possible. The fund is classified as “non-diversified,” which means the fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. Investments in securities of a limited number of issuers exposes the fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers. The fund will be sensitive to, and its performance will depend to a greater extent on, the overall condition of companies in the Nuclear Industries. Companies in the Nuclear Industries may face considerable risk as a result of, among other risks, incidents and accidents, breaches of security, ill-intentioned acts of terrorism, air crashes, natural disasters (such as floods or earthquakes), equipment malfunctions or mishandling in storage, handling, transportation, treatment or conditioning of substances and nuclear materials.

Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. Investments in securities of foreign companies involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies. Companies defined as small and mid-cap securities may involve greater risk than is normally associated with large cap companies, and as a result may be more volatile and less liquid than the securities of large-cap companies, and may have returns that vary substantially from the overall securities markets.

Shares of exchange-traded funds (ETFs) are not individually redeemable and owners of the shares may acquire those shares from the ETF and tender those shares for redemption to the ETF in Creation Units only, see the ETF prospectus for additional information regarding Creation Units. Investors may purchase or sell ETF shares throughout the day through any brokerage account, which will result in typical brokerage commissions.

Nothing contained in this communication constitutes tax, legal or investment advice. Investors must consult their tax advisor or legal counsel for advice and information concerning their particular situation.
