Frontier Nuclear Provides Corporate Update

Winnipeg, Manitoba–(Newsfile Corp. – March 23, 2026) – Frontier Nuclear and Minerals Inc., d/b/a Frontier Nuclear (NASDAQ: FNUC) (“Frontier”), a nuclear fuel cycle company, provides an update on its strategy and operations as it advances its transition toward a focused nuclear fuel cycle business.

Investment Thesis

Frontier is advancing a strategy to build a focused U.S. nuclear fuel cycle platform with exposure to uranium resources and select downstream technologies.

Frontier’s approach is based on:

• Developing a portfolio of U.S. uranium assets with potential for future production

• Maintaining targeted equity exposure to enrichment and reactor technologies

• Simplifying its asset base through the planned spin-off of non-core lithium assets

• Aligning with long-term demand for secure domestic nuclear fuel supply

Frontier’s objective is to establish a disciplined, strategically positioned presence across key segments of the nuclear fuel cycle.

CEO Commentary

“We continue to align Frontier around a focused uranium and nuclear fuel cycle strategy,” said Frank Wheatley, Chief Executive Officer.

“Our priority is to allocate capital prudently across opportunities where we believe we can build long-term value and strategic relevance within the U.S. nuclear fuel cycle. The planned spin-off of our lithium assets is intended to further simplify the business and enhance that focus.”

Strategic Focus

Frontier’s current activities are concentrated in three segments of the nuclear fuel cycle:

• Uranium mining and milling

• Uranium enrichment

• Small modular reactor technologies

Frontier’s uranium portfolio includes:

• Tallahassee Project (Colorado) – an established uranium resource base

• Pine Ridge Project (Wyoming) – an exploration-stage asset in the Powder River Basin

Frontier’s near-term focus is on advancing these assets through staged drilling, technical work programs, and development planning.

Frontier also holds equity interests in nuclear-related technologies:

• Ubaryon, a developer of uranium enrichment technology, in which Frontier is the largest shareholder alongside Urenco

• Kadmos Energy, an SMR-focused company pursuing deployment of light-water reactor technologies

These investments are intended to complement Frontier’s uranium asset base by providing measured exposure to additional segments of the nuclear fuel cycle.

Lithium Asset Spin-Off

Frontier is planning the spin-off of its lithium assets into an independent entity.

The proposed spin-off is intended to:

• Increase management focus on nuclear fuel cycle activities

• Establish distinct strategic and capital allocation priorities

• Improve transparency for shareholders

The structure, timing, and completion of any such transaction remain subject to further planning and required approvals.

2026 Priorities

Frontier’s priorities for 2026 include:

• Advancing its transition to a focused nuclear fuel cycle company

• Progressing uranium assets through technical and development milestones

• Supporting advancement of Ubaryon and Kadmos Energy

• Evaluating select opportunities aligned with its strategy
