In 2024, the oil and gas mergers and acquisitions activity reached levels not seen in years. What makes this consolidation wave particularly significant is that it occurred despite softer commodity prices, signaling a fundamental shift in industry strategy from growth-focused expansion to efficiency-driven consolidation.

A Record-Breaking Year for Energy Deals

Leading energy companies spent $206.6 billion on mergers and acquisitions in 2024, up from $47.9 billion the previous year, according to Ernst & Young’s industry study. This increase represents one of the most dramatic surges in deal-making activity the sector has experienced, with the total value reaching levels comparable to the industry’s previous peak periods.

The surge was driven by several megadeals that dominated headlines throughout 2024. Exxon Mobil was the biggest buyer in 2024 with total property acquisition costs of $84.5 billion, primarily through its landmark acquisition of Pioneer Natural Resources for $60 billion. Other major players followed suit, with Diamondback Energy and ConocoPhillips leading significant consolidation plays across the sector.

Driving Efficiency Through Scale

This consolidation wave represents a notable departure from previous industry cycles. Rather than pursuing aggressive growth strategies during favorable market conditions, companies are now prioritizing operational efficiency and scale advantages even as commodity prices retreat from their 2022 peaks. Companies flush with cash were focused on driving efficiency through scale, as industry experts noted.

The rationale behind these deals extends beyond simple asset accumulation. Companies are leveraging consolidation to optimize their operational footprints, streamline processes, and deploy advanced technologies across larger asset bases. This approach allows them to maintain profitability even in challenging price environments while building more resilient business models for the future.

Financial Discipline

Interestingly, the increased spending on acquisitions coincided with financial discipline in other areas. Oil and gas companies cut spending on dividends and share repurchase payments by about 25% last year to $29.2 billion, while exploration and development expenditure down 7% year on year at $85.5 billion. This reallocation of capital from shareholder returns and exploration to acquisitions reflects a mature industry’s calculated approach to long-term value creation.

Despite the aggressive dealmaking, profits fell 10% last year to $74.8 billion, less than half the record level recorded in 2022, primarily owing to soft commodity prices. This makes the surge in M&A activity even more remarkable, as companies chose to invest heavily in consolidation despite facing margin pressures.

Current Market Dynamics and Challenges

As we move through 2025, the oil and gas M&A is facing new realities. The industry opened in 2025 with $17 billion in deals, the second-best start since 2018, but it was powered by one company, with Diamondback Energy leading the charge through major Permian Basin acquisitions.

However, industry analysts are noting that this sector is heading into the most challenging conditions seen since the first half of 2020. High asset prices and limited opportunities colliding with weakening crude will create a complex environment for future dealmaking.
