• Phase 1 Capital Stack Complete: The Facility, together with proceeds from the Company’s March 2026 equity offering, provides funding visibility into Phase 1 construction of Big Sky, with initial commercial operations targeted for Q1 2027.

• Facility Structure: The $20 million facility is priced at the existing borrowing base grid plus 200 basis points (ABR + 2.25% to 3.25% depending on utilization), with no financial covenant testing until March 31, 2027, a final maturity of May 31, 2029, and no prepayment penalties.

• ELOC Formally Suspended: The ELOC has not been drawn since March 2, 2026. The Company is formally suspending further use of the facility, which addresses a perceived dilution overhang associated with the ELOC.

• Near-Term Execution Focus: With the Phase 1 capital stack in place, the Company’s focus shifts to plant construction and the near-term operational milestones previously outlined, including initial helium sales and carbon management operations targeted to commence in Q1 2027.

“The closing of this expanded facility completes the Phase 1 capital stack for Big Sky through a combination of the March 2026 equity offering and project-oriented senior secured debt,” said Ryan Smith, President and Chief Executive Officer. “We appreciate the continued support of our banking partners. The terms achieved here provide meaningful flexibility, with no financial covenant testing until March 31, 2027 and no prepayment penalties. The closing also allows us to formally suspend further use of our ELOC, which has not been drawn since March 2, 2026. Today’s announcement is intended to address a perceived dilution overhang tied to the ELOC and to allow investors to refocus on Phase 1 execution and the operational milestones ahead.”

Expanded Senior Secured Debt Facility

The expanded $20 million facility builds on the Company’s existing senior secured credit structure and is expected to provide the remainder of the development capital required to complete Phase 1 infrastructure at Big Sky. Key terms include:

• Increased Facility Size: $20 million

• Pricing: Existing borrowing base grid plus 200 basis points, ranging from ABR + 2.25% to ABR + 3.25% depending on utilization

• Financial Covenants: No financial covenant testing until March 31, 2027

• Maturity: May 31, 2029

• Prepayment: No prepayment penalties

Together with the proceeds of the Company’s equity capital markets activity completed in early March 2026, the facility is expected to complete the funding required to deliver Phase 1 of Big Sky into commercial operations.

The Facility includes customary hedging requirements, which the Company has satisfied. Additional detail regarding the Company’s hedge position will be provided in its upcoming quarterly results.

Equity Line of Credit – Formal Suspension

The Company maintains an existing equity line of credit, which has served as a flexible capital tool during earlier stages of the Big Sky development program. The ELOC was last utilized on March 2, 2026, with issuances on that date executed at an average price of $1.16 per share. No issuances have been made on the facility at any point thereafter.

With the Phase 1 capital stack now in place through the Facility and the March 2026 equity offering, the Company is formally suspending further use of the ELOC and does not anticipate drawing on it in connection with Phase 1.

Operational Update and Regulatory Milestones

The Company continues to advance commercial discussions with potential helium offtake partners for Big Sky against a tight global helium supply backdrop. Execution of a long-term helium offtake agreement in advance of commercial operations remains a targeted near-term catalyst.

The Company continues to advance the two Monitoring, Reporting, and Verification (“MRV”) plans previously submitted to the U.S. Environmental Protection Agency (EPA) for its Class II injection wells, the first of such submissions in the State of Montana. Based on the current progression of the EPA review process, approvals are anticipated during the summer of 2026, representing an important regulatory milestone supporting the Section 45Q tax credit framework central to the Big Sky economic model.
