US oil giant ConocoPhillips announces the acquisition of Marathon Oil, valued at $22.5 billion, including $5.4 billion in net debt. The deal is part of a series of major acquisitions in the US oil sector, defying calls for an energy transition. Indeed, giants such as ExxonMobil, Chevron and Occidental Petroleum have recently made significant buyouts. With Marathon Oil, ConocoPhillips is strengthening its presence in strategic regions such as the Bakken Basin and the Permian Basin, rich in shale oil and gas.

Strategic benefits of the acquisition

This acquisition enables ConocoPhillips to add an additional two billion barrels of resources to its US onshore portfolio. The companies emphasize the complementary nature of the assets, which will generate savings of $500 million in the year following the transaction, thanks in particular to reduced administrative and production costs. The agreement also calls for share buybacks worth over $20 billion over three years, including $7 billion in the first year.

Agreement details

Under the terms of the agreement, Marathon Oil shareholders receive 0.255 ConocoPhillips shares per share held, representing a 14.7% premium to Marathon Oil’s closing price. Scheduled to be completed by the end of 2024, this transaction is part of a consolidation trend in the US oil industry, aimed at strengthening positions in strategic regions and optimizing costs.

Climate pressures and shareholder reactions

This series of acquisitions comes at a time when the oil industry is facing increasing pressure to make the transition to cleaner energy sources. Despite this, major companies continue toinvest heavily in hydrocarbon development. At its Annual General Meeting, ConocoPhillips brings together its shareholders, who will have the opportunity to express their views on the company’s strategy in the face of climate change.

Shareholder reward strategies

In addition to the expected savings, ConocoPhillips plans to reward its shareholders with substantial share buybacks. These actions are designed to maintain investor confidence while navigating a complex and changing market environment. ConocoPhillips’ strategy reflects a balanced approach, seeking to maximize shareholder value while responding to the challenges of the energy market.

Future prospects and reflections

ConocoPhillips’ acquisition of Marathon Oil represents a major strategic move against a backdrop of climate pressures and growing energy demand. As the oil industry evolves, major companies must strike a balance between financial imperatives and societal expectations in terms of sustainability. Reactions from investors and climate activists will continue to influence the strategic decisions of ConocoPhillips and other industry players.
