RUBELLITE ENERGY CORP. ANNOUNCES DISPOSITION OF EAST EDSON NATURAL GAS ASSETS

CALGARY, AB, Sept. 8, 2026 /CNW/ -- Rubellite Energy Corp. ("Rubellite", or the "Company") is pleased to announce that it has sold its 50% non-operated working interest in the East Edson natural gas assets in West Central Alberta (the "East Edson Assets") to the third-party operator of the East Edson Assets (the "Purchaser") for total consideration of $67.0 million, satisfied through the delivery by the Purchaser to Rubellite of 2.083 million freely tradeable common shares of Topaz Energy Corp. (TSX: TPZ) ("Topaz") (the "Disposition"). The Disposition closed concurrently with the execution of a definitive agreement on September 8, 2026.

"The sale of the East Edson property transitions Rubellite back to a pure play heavy oil company, sharpening our focus on the multi-lateral horizontal development of our Clearwater and Mannville stack assets where Rubellite's technical expertise drives top-tier netbacks and capital efficiencies," said Sue Riddell Rose, President and CEO of Rubellite. "The Topaz shares received as consideration provide immediate, highly liquid value along with meaningful dividend income, while preserving exposure for our shareholders to a natural gas price recovery through a broader, diversified portfolio of assets, rather than a single, non-operated deep basin asset. The Disposition materially strengthens Rubellite's balance sheet and provides enhanced financial flexibility to accelerate our organic growth plans, advance waterflood development, pursue additional consolidation opportunities in our core Clearwater and Mannville stack fairways, and access other opportunities to further grow shareholder value."

TRANSACTION HIGHLIGHTS

• Total consideration of $67.0 million was satisfied through the delivery by the Purchaser to Rubellite of 2.083 million freely tradeable common shares of Topaz, at a deemed price of $32.1588 per share;
  
  
• Rubellite retained the net operating income⁽¹⁾ from the East Edson Assets through August 31, 2026 and will receive the September 2026 quarterly dividend on the Topaz shares of $0.35 per share (approximately $0.7 million);
  
  
• Transitions Rubellite back to a pure play heavy oil producer, increasing the Company's oil weighting to over 90% of production (from approximately 70%), and improving the Company's forecast 2027 operating netback⁽¹⁾ by approximately 27%;
  
  
• Establishes operatorship of greater than 98% of Rubellite's production, enhancing control over field operations and the timing of capital allocation decisions;
  
  
• Eliminates approximately $12 - $15 million per year of forecast sustaining capital expenditures⁽¹⁾ at East Edson, increasing forecast free funds flow⁽¹⁾ over the Company's five-year plan at current strip prices;
  
  
• The Topaz shares are expected to generate approximately $2.9 million per year of dividend income while held; and
  
  
• Materially strengthens Rubellite's balance sheet, reducing the Company's pro forma leverage ratio to approximately 0.7 times net debt to annualized adjusted funds flow⁽¹⁾, net of the market value of the Topaz shares, and enhancing liquidity and financial flexibility to fund future growth and acquisition opportunities.

STRATEGIC RATIONALE

• Re-establishes and clarifies Rubellite's pure play heavy oil, multi-lateral horizontal development business plan in the Clearwater and Mannville stack plays, with strong top tier netback metrics;
  
  
• Increases financial flexibility and liquidity, with the value of the highly liquid Topaz shares readily accessible to fund Rubellite's organic growth plans, waterflood advancement, future acquisitions and other value-enhancing opportunities;
  
  
• Improves the Company's forecast operating netback⁽¹⁾, free funds flow⁽¹⁾ and corporate production growth rate, and positions Rubellite for potential trading multiple expansion as a pure play Clearwater / Mannville stack heavy oil producer with a strengthened balance sheet and reduced risk profile; and
  
  
• Shifts Rubellite's natural gas price exposure from a single, non-operated, deep basin asset requiring ongoing capital investment, to a broad portfolio of assets managed as a going-concern business through an equity position in highly liquid publicly traded corporation, preserving the potential for incremental value recovery from the Disposition, while providing flexibility to manage the Company's business plan and funding requirements, and align with its outlook for future commodity prices.

TRANSACTION DETAILS

Under the terms of the Disposition, Rubellite sold to the Purchaser the East Edson Assets for aggregate consideration of $67.0 million. The consideration was satisfied through the delivery of 2.083 million freely tradeable common shares of Topaz, valued at the 10-day volume weighted average price of the Topaz shares on the TSX, ending three business days prior to the closing date, of $32.1588 per share. Rubellite will also receive the quarterly dividend of $0.35 per Topaz share payable in September 2026 (approximately $0.729 million) and retained the net operating income from the East Edson Assets through August 31, 2026.

The East Edson Assets comprised Rubellite's 50% non-operated working interest in approximately 29,000 net acres in the East Edson area of West Central Alberta, producing approximately 3,700 boe/d (forecast 2026 annual average; approximately 89% natural gas) from the Wilrich formation, together with associated interests in the West Wolf Lake 10-3 gas plant (50% working interest) and the Rosevear gas plant (7.5% working interest).

Rubellite's borrowing base under its first lien credit facility has been reconfirmed at $160 million, with the next scheduled semi-annual borrowing base redetermination on or before May 31, 2027.

ADVISORIES

INDUSTRY METRICS

This news release contains certain industry metrics which do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies and should not be used to make comparisons. Such metrics have been included in this document to provide readers with additional measures to evaluate Rubellite's performance; however, such measures are not reliable indicators of Rubellite's future performance and future performance may not compare to Rubellite's performance in previous periods and therefore such metrics should not be unduly relied upon. See "Non-GAAP and Other Financial Measures" in this news release for a description of these industry metrics.

BOE VOLUME CONVERSIONS

Barrel of oil equivalent ("boe") may be misleading, particularly if used in isolation. In accordance with NI 51-101, a conversion ratio for conventional natural gas of 6 Mcf:1 bbl has been used, which is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. In addition, utilizing a conversion on a 6 Mcf:1 bbl basis may be misleading as an indicator of value as the value ratio between conventional natural gas and heavy crude oil, based on the current prices of natural gas and crude oil, differ significantly from the energy equivalency of 6 Mcf:1 bbl.

ABBREVIATIONS

The following abbreviations used in this news release have the meanings set forth below:

bbl                 barrels
bbl/d              barrels per day
boe                barrels of oil equivalent
boe/d             barrels of oil equivalent per day

PRELIMINARY FINANCIAL INFORMATION

Certain financial and operating results included in this news release, including forecast production, net operating income, free funds flow, and operating netbacks, are based on preliminary and unaudited estimates as of the date of this news release. These estimated results are subject to change upon completion of the Company's unaudited interim financial statements for the period ended September 30, 2026.

NON-GAAP AND OTHER FINANCIAL MEASURES

Throughout this news release and in other materials disclosed by the Company, Rubellite employs certain measures to analyze financial performance, financial position and cash flow. These non-GAAP and other financial measures do not have any standardized meaning prescribed under IFRS and therefore may not be comparable to similar measures presented by other entities. The non-GAAP and other financial measures should not be considered to be more meaningful than GAAP measures which are determined in accordance with IFRS, such as net income (loss), cash flow from (used in) operating activities, and cash flow from (used in) investing activities, as indicators of Rubellite's performance.

Non-GAAP Financial Measures

Capital expenditures: Rubellite uses capital expenditures related to exploration and development to measure its capital investments compared to the Company's annual capital budgeted expenditures. Rubellite's capital budget excludes acquisition and disposition activities. Total capital expenditures includes exploration and development, land, geological and geophysical and corporate spending.

Net debt and adjusted working capital deficit: Rubellite uses net debt as an alternative measure of outstanding debt and is calculated by adding borrowings under the credit facility and term loan debt, less adjusted working capital and less the market value of the marketable securities related to the Topaz shares. Adjusted working capital is calculated by adding cash, accounts receivable, prepaid expenses and deposits and product inventory less accounts payable and accrued liabilities. Management considers net debt as an important measure in assessing the liquidity of the Company. Net debt is used by management to assess the Company's overall debt position and borrowing capacity. Net debt is not a standardized measure and therefore may not be comparable to similar measures presented by other entities.

Net Operating income or operating netbacks: Net operating income or operating netback is calculated by deducting royalties, net operating costs, and transportation costs from oil and natural gas revenue. Net operating income or operating netback is also calculated on a per boe basis using total production sold in the period. Rubellite considers net operating income or operating netback to be key industry performance indicators that provide investors with information that is also commonly presented by other oil and natural gas producers.

Adjusted funds flow: Adjusted funds flow is calculated based on net cash flows from operating activities, excluding changes in non-cash working capital and expenditures on decommissioning obligations, other provisions and cash-settled share based compensation since the Company believes the timing of collection, payment or incurrence of these items is variable. Expenditures on decommissioning and share based compensation obligations may vary from period to period and are managed as expenditures through the corporate budgeting process which considers available adjusted funds flow. Management uses adjusted funds flow and adjusted funds flow per boe as key measures to assess the ability of the Company to generate the funds necessary to finance capital expenditures, expenditures on decommissioning obligations, expenditures on share based compensation and meet its financial obligations. Adjusted funds flow is not intended to represent net cash flows from operating activities calculated in accordance with IFRS.

Free funds flow: Free funds flow is an important measure that informs efficiency of capital spent and liquidity. Free funds flow is calculated as adjusted funds flow generated during the period less capital expenditures, excluding non-cash items and acquisitions and dispositions. Adjusted funds flow and capital expenditures are non-GAAP financial measures which have been reconciled to their most directly comparable GAAP measures previously in this document. By comparing current period capital expenditures relative to adjusted funds flow, Rubellite monitors its free funds flow to inform decisions such as capital allocation, debt repayment and liquidity.

Net operating costs: Net operating costs equals operating expenses net of processing income, which is made up of processing revenue and other one time items from time to time. Management views net operating costs as an important measure to evaluate its operational performance. The most directly comparable IFRS measure for net operating costs is production and operating expenses.

Non-GAAP Financial Ratios

Rubellite calculates certain non-GAAP measures per boe as the measure divided by weighted average daily production. Management believes that per boe ratios are a key industry performance measure of operational efficiency and one that provides investors with information that is also commonly presented by other crude oil and natural gas producers. Rubellite also calculates certain non-GAAP measures per share as the measure divided by outstanding common shares.

Net debt to annualized adjusted funds flow ratio: Net debt to annualized adjusted funds flow ratios are calculated by annualizing the current quarter adjusted funds flow.

Supplementary Financial Measures

"Exploration and development spending" is comprised of the non-GAAP measure total capital expenditures (as calculated above), less land, geological and geophysical and corporate and other spending.

"Royalties as a percentage of revenue" is comprised of royalties, as determined in accordance with IFRS, divided by total oil and natural gas revenue, as determined in accordance with IFRS.

"Net operating costs ($/boe)" is comprised of net operating cost (as calculated above), divided by the Company's total sales production.

"Transportation costs ($/boe)" is comprised of transportation, as determined in accordance with IFRS, divided by the Company's total sales production.

"G&A costs ($/boe)" is comprised of G&A expense, as determined in accordance with IFRS, divided by the Company's total sales production.

"Heavy oil wellhead differential ($/bbl)" represents the differential the Company receives for selling its heavy oil production relative to the Western Canadian Select reference price (CAD$/bbl), prior to any price or risk management activities.
