Summary

Magnolia Oil & Gas filed comprehensive financial documentation for its previously announced $4.1 billion acquisition of WildFire Energy, a Houston-based Eagle Ford operator. The deal adds approximately 810,000 net acres across nine East Texas counties, current production of 53 MBoe/d (70% oil weight), and 271.2 million barrels of oil equivalent in proved reserves.

Magnolia is funding the transaction through a mix of 32.2 million shares, $2.7 billion cash (sourced from a $970 million equity offering, $1.1 billion revolver draw, $500 million in new 7% senior notes, and $100 million cash on hand), plus assumption of WildFire's $600 million 7.5% notes due 2029. However, Q1 2026 results reversed sharply with a $147 million net loss due to $273 million in derivative losses, illustrating the volatility of WildFire's hedged position. An independent reserve report by Netherland, Sewell & Associates valued WildFire's 196.5 MMBoe of proved reserves at $4.1 billion PV-10 using SEC pricing ($65.1 million/bbl WTI, $3.1 million/MMBTU Henry Hub). On a pro forma basis, the combined entity would hold 481.4 MMBoe of proved reserves with a $6.6 billion standardized measure, though Q1 2026 pro forma results show a combined net loss of $70.8 million ($0.28/share) versus Magnolia's standalone profit of $99.8 million, reflecting the financing costs of the transaction. Magnolia entered the deal with a strong balance sheet—$295.9 million cash and zero revolver draw as of June 30, 2026—providing capacity to absorb the $1.1 billion senior secured credit facility draw and integrate the acquired assets, secured by a first-priority lien on substantially all assets of the borrower and guarantors.

Added Pricing assumptions medium

Added in current filing · view on EDGAR →

Prices used in this report are based on the 12-month unweighted arithmetic average of the first-day-of-the-month price for each month in the period January through December 2025. For oil and NGL volumes, the average West Texas Intermediate spot price of $66.01 per barrel is adjusted for quality, transportation fees, and market differentials. For gas volumes, the average Henry Hub spot price of $3.387 per MMBTU is adjusted for energy content, transportation fees, and market differentials.

The reserve valuation uses SEC-compliant 12-month average pricing: WTI crude at $65.1 million/barrel and Henry Hub gas at $3.387/MMBTU for the January-December 2025 period. These prices are held constant over the life of the properties and adjusted for quality and transportation to yield weighted average realized prices of $65.20/barrel oil, $20.26/barrel NGL, and $2.716/MCF gas for proved reserves.
