Expand Energy Corporation is North America’s largest natural gas producer, formed on 1 October 2024 through the $7.4 billion merger of Chesapeake Energy and Southwestern Energy. The combined company trades on NASDAQ under the ticker EXE and produced approximately 7.4 billion cubic feet equivalent per day in 2025 — representing around 7% of total US natural gas output — with a 2026 production target of 7.5 Bcfe/d across three major shale basins.
Expand Energy Chesapeake Southwestern: How the Merger Was Built
Chesapeake Energy announced its intention to acquire Southwestern Energy in January 2024 through an all-stock deal valued at $7.4 billion. Chesapeake shareholders retained approximately 60% of the combined company with Southwestern shareholders receiving the remainder. The merger cleared Hart-Scott-Rodino antitrust review in September 2024 and closed on 1 October 2024, with the combined entity immediately rebranding as Expand Energy Corporation and commencing trading on NASDAQ under the EXE ticker.
The strategic rationale was scale and basin diversification. Chesapeake brought dominant Haynesville Shale positioning in Louisiana — the US basin closest to Gulf Coast LNG export terminals — while Southwestern contributed major Northeast and Southwest Appalachia operations giving the combined company exposure to both the Atlantic export corridor and domestic demand centres in the Northeast. The merger created the largest operator in the Haynesville with a post-merger holding of 650,000 net acres.
The expand energy chesapeake southwestern combination also carried significant balance sheet ambition. Gross debt has been reduced by approximately $1.25 billion since merger close, with the credit facility upsized to $3.5 billion and extended to 2030 — giving the company financial flexibility to pursue further leasehold acquisitions and infrastructure investments.
Production and Financial Performance in 2025
Expand Energy’s first full year of operation as a merged entity delivered substantial results. Total revenue for fiscal year 2025 reached $12.1 billion, compared with $4.2 billion in 2024 — reflecting the full-year consolidation of Southwestern’s production. Net income was $1.8 billion, or $7.57 per diluted share, reversing a net loss of $714 million in 2024.
Q4 2025 production reached 7,400 MMcfe/d across three operating segments. Haynesville contributed 3,193 MMcfe/d with capital expenditure of $367 million in the quarter. Northeast Appalachia produced 2,610 MMcfe/d with segment capex of $207 million. Southwest Appalachia — the Southwestern Energy legacy basin — produced 1,597 MMcfe/d, with production approximately 65% natural gas, 30% NGLs, and 5% oil.
The company managed an average of 12 rigs during Q4 2025, drilling 51 wells and turning 66 wells in line. Haynesville breakevens improved approximately 15% during 2025 as integration synergies were captured ahead of schedule. For 2026, management has guided production of approximately 7.5 Bcfe/d — representing continued growth from the merger baseline.
LNG Supply Strategy and Gas Market Positioning
The expand energy chesapeake southwestern combination was explicitly structured around the growing US LNG export market. Haynesville Shale gas is geographically proximate to Gulf Coast export terminals including Sabine Pass, Cameron LNG, and the under-construction Commonwealth LNG and Golden Pass facilities — giving Expand Energy a structural freight advantage over Appalachian producers supplying the same markets via longer pipeline routes.
In Q3 2025, Expand Energy signed a 15-year sales and purchase agreement with Lake Charles Methanol to serve as sole gas supplier, with a start date of approximately 2030 and pricing at a premium to NYMEX. FID on that project is expected in 2026. In October 2025, the NG3 pipeline entered service, increasing Expand Energy’s transport capacity to the Gulf Coast and strengthening its ability to move Haynesville volumes directly to LNG export customers.

Leasehold Expansion and 2026 Outlook
Beyond operational integration, Expand Energy has been actively expanding its resource base. In the second half of 2025 the company acquired approximately 82,500 net acres of leasehold across Western Haynesville and Southwest Appalachia. The Western Haynesville position — established through targeted leasing and an undeveloped leasehold acquisition at total land spend of approximately $178 million including future capital carry — has the potential to yield more than 200 additional development locations.
The company also completed a Western Haynesville leasehold transaction in Q4 2025, adding approximately 200 near-term locations to its inventory. These additions position Expand Energy to sustain production growth through the late 2020s as LNG export demand and domestic gas-fired power generation continue to expand.
