• ConocoPhillips expects to achieve at least $500 million of run rate cost and capital savings within the first full year following the closing of the transaction.
• Independent of the transaction, ConocoPhillips expects to increase its ordinary base dividend by 34% to 78 cents per share starting in the fourth quarter of 2024.

ConocoPhillips (NYSE: COP) and Marathon Oil Corporation (NYSE: MRO) announced today that they have entered into a definitive agreement pursuant to which ConocoPhillips will acquire Marathon Oil in an all-stock transaction with an enterprise value of $22.5 billion, inclusive of $5.4 billion of net debt. Under the terms of the agreement, Marathon Oil shareholders will receive 0.2550 shares of ConocoPhillips common stock for each share of Marathon Oil common stock, representing a 14.7% premium to the closing share price of Marathon Oil on May 28, 2024, and a 16.0% premium to the prior 10-day volume-weighted average price.

“This acquisition of Marathon Oil further deepens our portfolio and fits within our financial framework, adding high-quality, low cost of supply inventory adjacent to our leading U.S. unconventional position,” said Ryan Lance, ConocoPhillips chairman and chief executive officer. “Importantly, we share similar values and cultures with a focus on operating safely and responsibly to create long-term value for our shareholders. The transaction is immediately accretive to earnings, cash flows and distributions per share, and we see significant synergy potential.”

“This is a proud moment to look back on what we achieved at Marathon Oil. Powered by our dedicated employees and contractors, we built a top performing portfolio with a multi-year track record of peer-leading operational execution, strong financial results and compelling return of capital to our shareholders - all while holding true to our core values of safety and environmental excellence. ConocoPhillips is the right home to build on that legacy, offering a truly unique combination of added scale, resilience and long-term durability. With its premier global asset base, strong balance sheet and laser focus on operational excellence, ConocoPhillips’ track record of long-term investments, differentiated shareholder distributions and active portfolio management are unmatched. When combined with the global ConocoPhillips portfolio, I’m confident our assets and people will deliver significant shareholder value over the long term,” said Lee Tillman, Marathon Oil chairman, president and chief executive officer.

Transaction benefits

• Immediately accretive: This acquisition is immediately accretive to ConocoPhillips on earnings, cash from operations, free cash flow and return of capital per share to shareholders.
• Delivers significant cost and capital synergies: Given the adjacent nature of the acquired assets and a common operating philosophy, ConocoPhillips expects to achieve the full $500 million of cost and capital synergy run rate within the first full year following the closing of the transaction. The identified savings will come from reduced general and administrative costs, lower operating costs and improved capital efficiencies.
• Further enhances premier Lower 48 portfolio: This acquisition will add highly complementary acreage to ConocoPhillips’ existing U.S. onshore portfolio, adding over 2 billion barrels of resource with an estimated average point forward cost of supply of less than $30 per barrel WTI.

Return of capital update

Independent of the transaction, ConocoPhillips expects to increase its ordinary base dividend by 34% to 78 cents per share starting in the fourth quarter of 2024. Upon closing of the transaction and assuming recent commodity prices, ConocoPhillips plans to:

• Repurchase over $7 billion in shares in the first full year, up from over $5 billion standalone.
• Repurchase over $20 billion in shares in the first three years.

“We remain committed to our differentiated cash from operations distribution framework of returning greater than 30% to our shareholders, with a track record of returning over 40% since our 2016 strategy reset,” added Lance. “We plan to raise our ordinary dividend by 34% in the fourth quarter and we will continue to target top-quartile dividend growth relative to the S&P 500 going forward. Additionally, we intend to prioritize share repurchases following the close of the transaction, with a plan to retire the equivalent amount of newly issued equity in the transaction in two to three years at recent commodity prices.”

Transaction details

The transaction is subject to the approval of Marathon Oil stockholders, regulatory clearance and other customary closing conditions. The transaction is expected to close in the fourth quarter of 2024.

Use of Non-GAAP Financial Information and Other Terms – This news release contains certain financial measures that are not prepared in accordance with GAAP, including cash from operations (CFO), free cash flow and net debt. CFO is calculated by removing the impact from operating working capital from cash provided by operating activities. Free cash flow is CFO net of capital expenditures and investments. Net debt is total balance sheet debt less cash, cash equivalents and short-term investments. This news release also contains the terms enterprise value, cost of supply and return of capital. Enterprise value included in this release is calculated based on the sum of net debt as of March 31, 2024, and anticipated shares to be issued at the fixed exchange ratio of 0.2550 measured at ConocoPhillips' closing share price on May 28, 2024. Cost of supply is the WTI equivalent price that generates a 10 percent after-tax return on a point-forward and fully burdened basis. Fully burdened includes capital infrastructure, foreign exchange, price-related inflation, G&A and carbon tax (if currently assessed). If no carbon tax exists for the asset, carbon pricing aligned with internal energy scenarios are applied. All barrels of resource are discounted at 10 percent. Return of capital is defined as the total of the ordinary dividend, share repurchases and variable return of cash (VROC).

Cautionary Note to U.S. Investors – The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable and possible reserves. We may use the term “resource” in this release that the SEC’s guidelines prohibit us from including in filings with the SEC. U.S. investors are urged to consider closely the oil and gas disclosures in our Form 10-K and other reports and filings with the SEC. Copies are available from the SEC and from the ConocoPhillips website.
