River1 Launches BUIL, the Rebuild America ETF, Bringing Builder-Informed Investing Rooted in one of the largest privately held infrastructure companies in the U.S.

Actively managed ETF targets companies positioned to benefit as power, grid capacity, manufacturing and infrastructure investment accelerate across the U.S.

MILWAUKEE, Sept. 16, 2026 /PRNewswire/ -- River1 Asset Management LLC (River1) today announced the launch of the Rebuild America ETF (Cboe BZX: BUIL), an actively managed exchange-traded fund designed to invest in the companies helping meet the growing physical infrastructure buildout of the United States.

BUIL launches as a major new investment cycle takes shape across American power generation and transmission, manufacturing, construction and materials. Utilities are planning approximately $1.4 trillion in electricity infrastructure investment through 2030, according to the Edison Electric Institute, while the Electric Power Research Institute projects that data centers could account for 9% to 17% of U.S. electricity consumption by 2030, compared with roughly 4% to 5% today. Reshoring and renewed domestic manufacturing investment are adding further demand for power, materials and construction capacity.

Launched by River1 following the 2024 debut of the Trenchless Fund ETF (NYSE Arca: RVER), BUIL is designed to give investors liquid public-market exposure to that multi-year investment cycle, through a concentrated portfolio rather than a broad infrastructure index. River1 expects the strategy to span companies involved in areas including energy and power, electrical-grid infrastructure, construction, materials and data-center infrastructure.

River1 was established by principals associated with the Michels family office and draws upon decades of experience investing in and studying infrastructure-related industries. That background contributes to River1's long-term understanding of infrastructure markets and industry trends. River1's investment team combines traditional fundamental research with extensive experience analyzing infrastructure-related industries and markets.

Tony Tagliapietra, CEO, and Rob Haugen, CIO respectively of River1, and BUIL portfolio managers, each bring more than 25 years of investment experience including work with major hedge funds and mutual funds. Their approach combines traditional fundamental analysis with insights drawn from an infrastructure ecosystem that sees the buildout happening in real time. BUIL was developed to bring those two disciplines together in a concentrated, actively managed public-market portfolio.

"A career investing in infrastructure with a front-row seat to what is actually being built in America is the ideal insight engine for the rebuild America market story," said Tagliapietra, CEO, River1 Asset Management. "Our investment process includes extensive industry research, company engagement, supply-chain analysis and fundamental valuation work designed to help identify opportunities across the infrastructure ecosystem. BUIL grew from the idea that those insights should make us better infrastructure investors."

That research approach is already revealing significant insights to the multi-year lead times for natural gas turbines, shortages of low-voltage wire and increasing pressure on U.S. electrical-grid capacity as examples of the real-world signals that can help shape the portfolio.

River1 evaluates investment themes by comparing market expectations against publicly available industry data, company disclosures, and broader infrastructure trends.

"There is an enormous amount of capital going into rebuilding and expanding the physical backbone of the U.S. economy," said Haugen, CIO, River1 Asset Management. "The opportunity keeps moving. Today the constraint might be generation capacity, tomorrow it may be transmission, equipment, or materials. An active ETF gives us the ability to follow those capacity-constraints as they move through the system."

The fund will hold approximately 15 to 25 publicly traded companies selected through fundamental analysis of cash flow, growth, valuation and margin durability, together with an assessment of how directly each business can benefit from the infrastructure buildout. River1 will actively adjust the portfolio as supply constraints, pricing power and spending move through the infrastructure value chain.

The Rebuild America ETF (BUIL) is an actively managed ETF focused on publicly traded companies positioned within the ongoing expansion and rebuilding of U.S. infrastructure. The fund uses fundamental analysis alongside River1's builder-informed¹ research process to identify companies operating at critical points in the infrastructure value chain. The BUIL ETF has an annual expense ratio of 0.65%. Sound Capital serves as adviser to the fund and River1 Asset Management LLC serves as sub-adviser. [river1.us/buil/prospectus.]

Investing involves risk. Loss of principal is possible.

Non-Diversification Risk. A non-diversified fund under the federal securities laws may hold a significant percentage of its assets in the securities of relatively fewer companies or even one company; therefore, events affecting those companies have a greater impact on the Fund than on a diversified fund. Equity Securities Risk. The risks that could affect the value of the Fund's shares and the total return on your investment include the possibility that the equity securities held by the Fund will experience sudden, unpredictable drops in value or long periods of decline in value. New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision. ETF Risk. ETFs may trade at a premium or discount to NAV. Shares of any ETF are bought and sold at market prices (not NAV) and are not individually redeemed from the Fund. Brokerage commissions will reduce returns. Market risks, including political, regulatory, market, and economic or other developments, and developments that impact specific economic sectors, industries or segments of the market, can affect the value of the Fund's shares. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the market generally and on specific securities. The Fund is subject to the risk that the prices of, and the income generated by, securities held by the Fund may decline significantly and/or rapidly in response to adverse issuer, political, regulatory, general economic and market conditions, or other developments, such as regional or global economic instability (including terrorism and related geopolitical risks), interest rate fluctuations, and those events directly involving the issuers that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment.
