Lee Tillman
Chairman, President and Chief Executive Officer at Marathon Oil
Thank you, Guy, and good morning to everyone listening to our call today. To start, I want to thank our employees and contractors for their dedication and hard work during these most dynamic times as well as our commitment to our core values of safety and environmental excellence. In light of current events, including geopolitical tensions, economy-wide inflationary pressures and the highest global energy costs we have seen in some time. I want to briefly provide some context around the current energy market. First, we believe Marathon Oil as a global oil and gas producer has a clear and much-needed role to play in the longer-term energy landscape. This belief has only been reinforced as energy markets have struggled to respond to a confluence of factors, continued demand recovery from the pandemic, struggling global supply chain, labor shortages in a fully employed U.S. labor market and systemic underinvestment in both new oil and gas supply and the requisite infrastructure.
The invasion of the Ukraine by Russian forces has only exacerbated these pressures, upending geopolitics and creating a level of uncertainty and hostility between NATO and Russia that has not been experienced since the Cold War. The reality is that energy markets were already tightening from supply and demand fundamentals before this Russian action, and the risk premium now embedded in commodities, including oil and gas, has returned with a vengeance. Even in the unlikely event of a near-term resolution to this crisis, the die has been cast in actions, particularly by European countries are already underway to move away from Russian oil and gas and secure more reliable supply from the Middle East and the U.S. And here at home, these events are only adding to an inflationary environment that has once again put energy on center stage, inflation that impacts every American family.
It has underscored the need for an orderly energy transition that includes oil and gas as part of an all of the above strategy and has recalibrated global views as to the current and ongoing role of U.S. oil and gas and the world economy. Our mandate is clear, and it is a statement of Marathon Oil's corporate purpose. To help responsibly meet the world's growing energy needs by operating with the highest standards, prioritizing all elements of our safety, environmental, social and governance performance while delivering strong financial returns for our shareholders. Oil and gas are essential to any orderly multi-decade transition to a lower carbon future. Rather than an energy transition, it is more of an energy expansion to both meet growing world energy demand and mitigate global GHG emissions. This is not an iron ore proposition and failure on either front is not acceptable. However, our approach must be pragmatic and grounded in the free market, innovation and in all of the above energy approach.
Company strategies grounded in free market principles and a thoughtful analysis of competitive dynamics and long-term fundamentals are good for energy stability and security, the U.S. consumer and the longer-term health of our industry. At Marathon Oil, we have conviction that we are pursuing the right strategy for shareholders and stakeholders alike. It's best summarized by our framework for success on slide four of our deck, strong corporate returns, sustainable free cash flow and meaningful return of capital to our shareholders through the commodity price cycle, all underpinned by a high-quality portfolio, a bullet-proof balance sheet and a transparent commitment to comprehensive ESG excellence. Importantly, first quarter represented another quarter of comprehensive delivery against this framework. I would like to focus on three key takeaways today. First, we are continuing to build a peer-leading track record and, quite frankly, a market-leading track record of return of capital to our shareholders. Our cash flow-driven return of capital model uniquely prioritizes our equity investors as the first call on cash flow, not the drill bit.
And our continued execution underscores our commitment to our shareholders, and highlights the power of our portfolio in a constructive price environment. Over the trailing two quarters, we've returned around 60% of our CFO are over $1.4 billion to our shareholders. To clarify, that 60% of our cash flow from operations, not our free cash flow. This actually equates to almost 80% of our free cash flow over the same period. In total, we have now executed over $1.6 billion of share repurchases since last October, driving an 11% reduction to our outstanding share count in just seven months. And those shares were repurchased at a price below $19 a share, a discount of over 25% relative to today's trading price, demonstrating the power of consistent dollar averaging. We are significantly growing all of the per share financial metrics that matter most to our equity valuation. Under current market conditions and given our free cash flow yield, we continue to believe buybacks remain an excellent use of capital.
And consistent with that view, our Board of Directors has increased our outstanding buyback authorization to $2.5 billion. We also just raised our quarterly base dividend for the fifth consecutive quarter. My second key point is that first quarter was again another quarter of solid, consistent execution. We generated $1.3 billion of cash flow from operations and $940 million of free cash flow, both before working capital at a reinvestment rate of just 27%. And we returned $640 million or 50% of that CFO back to our shareholders. This strong financial performance was underpinned by solid operational execution, consistent with the guidance we provided on last quarter's call, including $348 million of capital spending and 168,000 barrels of oil production per day. My third key takeaway is that Marathon Oil represents a truly compelling investment opportunity. We've rebased our 2022 financial outlook to pricing more consistent with the current environment, $100 WTI and $6 Henry Hub.
At these prices, we expect to generate over $4.5 billion of free cash flow this year at a reinvestment rate of just 20%. That translates to a free cash flow yield of about 25% on the current equity value. That also a $1.5 billion free cash flow uplift versus the initial financial outlook we provided the market in February, net of $100 million of incremental capital inflation and at a lower reinvestment rate. This uplift highlights our unique torque to higher commodity prices due to our more advantaged cash tax outlook, preservation of our upside exposure through our hedge book and balanced commodity exposure. This includes our unique integrated gas position in Equatorial Guinea, where we are raising our annual equity income guidance by $200 million or by 67%. I've long said that our company and our sector must deliver truly outsized financial outcomes relative to the S&P 500 during periods of constructive pricing to attract increased investor sponsorship. We are successfully delivering on this obligation. I will now pass it off to Dane, who will give you a financial update, highlighting how most of the free cash flow I just mentioned will be going back to our equity holders.
