IsoEnergy and DISA Technologies to Form DISA
Uranium Corporation, Creating a Technology-Enabled U.S. Uranium Platform for Production, Processing, and Remediation
DISA Uranium Receives US$105
million in Financing Commitments, Backed by Consortium of Leading Strategic Investors
TORONTO, Aug. 4, 2026 /CNW/ - IsoEnergy Ltd. ("IsoEnergy")
(NYSE American: ISOU) (TSX: ISO) is pleased to announce that it has entered into a definitive agreement with DISA Technologies,
Inc. ("DISA") to create DISA Uranium™ Corporation ("DISA Uranium" or the "Company"),
a new technology-enabled U.S. uranium company positioned to strengthen domestic uranium supply and support the growing demand for secure,
U.S.-sourced nuclear fuel.
Pursuant to the definitive agreement, IsoEnergy will
contribute its portfolio of permitted, past-producing conventional uranium mines in Utah, comprising the Tony M Mine, Daneros Mine, Rim
Mine, Sage Plain Project, and Flatiron Project (the "Utah Portfolio") to DISA Uranium, in exchange for 1,677,350 shares
of Common Stock of the Company (the "Transaction"). DISA Uranium will combine IsoEnergy's Utah Portfolio with DISA's
proprietary High-Pressure Slurry Ablation processing technology ("HPSA™") and remediation and recovery business.
In connection with the Transaction, DISA Uranium has
received commitments for a concurrent US$105 million private placement financing (the "Financing") supported by a consortium
of leading mining, energy, and technology investors, including Tembo Capital, BHP Ventures, Galvanize Climate Solutions, Valor Equity
Partners, Evok Innovations, Halliburton Labs, and Veriten. IsoEnergy has agreed to participate in the Financing in the amount of US$33
million. Proceeds from the Financing are anticipated to be used to advance DISA Uranium's conventional mine development, fund remediation
and recovery programs, progress domestic uranium milling infrastructure, and support the Company's long-term growth.
Based on the financing commitments received, DISA
Uranium's implied pro forma fully diluted equity value would be approximately US$505 million. IsoEnergy will own approximately 33% of
the Company's issued and outstanding shares on a fully diluted basis and will be DISA Uranium's single largest shareholder.
Strategic Rationale for the Transaction
| • | Creates a Leading U.S. Conventional Uranium Platform |
| • | Combines IsoEnergy's portfolio of permitted past-producing
conventional uranium mines and exploration projects in Utah with DISA Uranium's proprietary HPSA™ processing technology
to create an integrated and differentiated U.S.-focused uranium company. |
| • | Unlocks a Large, Untapped Domestic Resource Through Remediation
and Recovery |
| • | DISA Uranium's remediation and recovery business addresses
the thousands of abandoned uranium mine ("AUM") sites across the western United States, recovering the uranium contained
in legacy waste. |
| • | Supported by the only U.S. Nuclear Regulatory Commission
("NRC") Source Materials License for uranium recovery from legacy waste across multiple sites, this pipeline provides
access to a significant, largely untapped domestic resource that requires no new mining, complements the Utah Portfolio as feedstock for
future processing capacity, and addresses a decades-old environmental liability. |
| • | Transformational HPSA™ Processing Technology Provides
Economic Advantage |
| • | HPSA™ has the potential to significantly reduce operating
costs by upgrading mineralized feedstock and reducing waste volumes. |
| • | Preliminary testing at the Tony M Mine demonstrated the potential
to reduce feedstock mass to ~22% of its original volume while recovering ~88% of the uranium. |
| • | Foundation for New U.S. Processing Infrastructure |
| • | Over time, the combined resource base may provide the scale
to support development of a centralized uranium recycling and processing facility, which would become the first new conventional uranium
mill constructed in the United States in more than four decades. |
| • | Strategy aligns with IsoEnergy's goal of building a multi-asset
uranium producer in tier one jurisdictions. |
| • | Experienced Team, Backed by a Consortium of Leading Strategic
Investors |
| • | To be led by the founders who took HPSA™ from concept
to the first-of-its kind NRC Source Materials License, supported by a deep bench including former NRC commissioner, regulatory, operational
and technical experts. |
| • | Anchored by leading mining, energy, and technology strategic
investors including Tembo Capital, BHP Ventures, Galvanize Climate Solutions, Valor Equity Partners, Evok Innovations, Halliburton Labs,
and Veriten. |
| • | Aligned with U.S. Energy Security Priorities |
| • | Strategically positioned to capitalize on accelerating investment
in the U.S. uranium supply chain, driven by energy security, AI-powered electricity demand, and federal support. |
| • | Enhanced Platform for Regional Consolidation |
| • | DISA Uranium is expected to have the scale, asset quality,
and growth profile to differentiate it within the uranium sector, and when combined with its technology-driven
cost advantage and vertically integrated platform, will create a unique opportunity to drive further regional consolidation. |
Philip Williams, Chief Executive Officer and Director
of IsoEnergy, commented, "The creation of DISA Uranium marks an important step in advancing IsoEnergy's strategy of building a
globally diversified, development ready uranium platform. By contributing our permitted, past-producing Utah asset base and pairing it
with DISA's proprietary HPSA™ technology, we believe we can enhance project economics, expand the universe of viable conventional
uranium resources, and ultimately support domestic processing infrastructure. At a time when the United States is placing renewed emphasis
on nuclear energy, energy security, and the reshoring of its nuclear fuel supply chain, we believe this partnership is both timely and
highly differentiated. For IsoEnergy and its shareholders, it unlocks value of our U.S. portfolio, while retaining direct, meaningful
exposure to the growth of a unique platform designed to help reshape domestic uranium production."
Greyson Buckingham, Chief Executive Officer of DISA
Uranium, commented, "DISA Uranium was built on a straightforward idea: much of the uranium this country needs is already out of
the ground, sitting in waste piles across the West. Remediating those abandoned mine sites and recovering the uranium and vanadium they
hold is the core of our business, and the reason we hold the only NRC license of its kind. IsoEnergy's Utah Portfolio extends that platform
- HPSA™ is designed to make those conventional assets meaningfully more economic by upgrading feedstock at the mine site and reducing
what has to be transported and processed. Together, recovered legacy material and a scaled conventional resource base give us the feedstock
to bring to life a new domestic uranium recycling and processing facility, the missing link in rebuilding an independent American nuclear
fuel supply. With the support of this investor group, DISA Uranium is positioned to move quickly."
Benefits to IsoEnergy Shareholders
As the single largest shareholder of DISA Uranium,
the Transaction will provide IsoEnergy's shareholders with exposure to a differentiated U.S. uranium platform underpinned by the following
strategic benefits:
| • | Exclusive rights to proprietary HPSA™ technology relating
to uranium production provide a transformative economic advantage and clear path to production for the Utah Portfolio. |
| • | Reinforced strategic position within U.S. domestic nuclear
fuel supply chain with expanded U.S. production capacity from DISA Uranium's expansive pipeline of legacy abandoned uranium remediation
sites and other regional conventional uranium deposits, supported by the only U.S. NRC Source Materials License for uranium recovery from
legacy waste across multiple sites. |
| • | Aligned with national priority to rebuild and secure the
domestic nuclear fuel supply chain, supported by established relationships across federal, state, and tribal governments and a demonstrated
record of executing alongside public and private sector partners at abandoned uranium mine sites on federal and tribal lands. IsoEnergy
and DISA have agreed to explore opportunities to collaborate with respect to the marketing and sale of uranium produced. |
| • | Robust financial sponsorship provides flexibility and support
to rapidly advance strategic initiatives and pursue future growth opportunities. |
| • | Enhances IsoEnergy's differentiated
portfolio of equity and strategic investments, providing investors with exposure across the uranium value chain and the potential for
re-rating. |
About HPSA™ Technology and U.S. Uranium Platform
HPSA™ is DISA's patented, modular mineral liberation
technology that uses high-velocity slurry streams to generate particle-on-particle collisions, causing material to fracture along natural
mineral grain boundaries. Unlike conventional mineral processing methods that rely on grinding media and chemical reagents, HPSA™
mechanically separates target minerals from host material, upgrading feed by concentrating valuable minerals into a smaller volume for
downstream transportation and processing. The technology has advanced beyond the pilot stage and has been commercially validated, with
eight continuous HPSA™ units deployed across four continents in mining applications.
Test work on mineralized material from IsoEnergy's
Tony M Mine demonstrated the potential for approximately 4x grade uplift, 78% reduction in material volumes requiring transportation,
and approximately 88% uranium recovery, highlighting HPSA™'s potential to significantly improve the economics of conventional uranium
production.
DISA Uranium's proprietary technology is complemented
by a unique remediation platform. Through the only U.S. NRC Source Materials License authorizing uranium recovery from legacy mine waste
across multiple sites, the Company is positioned to remediate historic environmental liabilities while recovering uranium and other valuable
minerals. This creates a differentiated opportunity to address a significant domestic remediation challenge, including more than 15,000
sites associated with abandoned mine waste, over 4,200 defense-related uranium mines.
Together, DISA Uranium's proprietary technology, unique
remediation platform, and commercially validated processing capabilities position the Company to improve the economics of conventional
uranium production while addressing legacy uranium mine remediation, creating a differentiated platform to support the rebuilding of the
U.S. domestic uranium supply chain.
Board of Directors and Management
Upon closing of the Transaction and Financing, the
senior management team of DISA Uranium will be led by Greyson Buckingham, Chief Executive Officer and Co-Founder of DISA, as well as a
10-year veteran of the U.S. Army National Guard, together with the existing DISA management team headquartered in Casper, Wyoming. The
Company will also benefit from a highly experienced board, with deep expertise across nuclear regulation, permitting, public policy, and
uranium project development, including two designees from IsoEnergy, expected to be Chairman Richard Patricio and IsoEnergy CEO and Director
Phillip Williams, and one designee from Tembo Capital Partner, George Pyper, as well as current DISA Board of Directors, Greyson Buckingham,
Scott Saxberg, Marty Reed, and former U.S. NRC Commissioner Jeffrey Merrifield.
IsoEnergy's experienced Utah operations team will
also transition to DISA Uranium with the Utah Portfolio, ensuring continuity as the Utah operations, particularly the Tony M Mine, advances
