The nation's biggest oil and gas companies have significantly increased stock buybacks and dividends since Russia invaded Ukraine in late February, raising questions about whether the firms are using wartime profits to enrich investors instead of curbing Americans' pain at the pump. The report released today by Friends of the Earth, Public Citizen and BailoutWatch turns up the heat on the fossil fuel industry ahead of two high-profile congressional hearings this week, when Democrats plan to scrutinize the industry's windfall profits amid rising crude prices sparked by the war in Ukraine. The three groups looked at Securities and Exchange Commission filings and public statements from the 20 largest U.S.-headquartered oil and gas companies. In January and February, seven companies' boards authorized their corporate treasuries to buy back and retire $24.35 billion in stock " a 15 percent increase over all of the buybacks authorized in 2021. Six of those decisions came in February, after fears of Russian aggression against Ukraine lifted stock prices. In total, the 20 companies announced $45.6 billion in stock buybacks since the start of 2021. More than half of the companies boosted their dividends in January and February. Of the 11 companies raising their dividends, nine were increases of more than 15 percent and four were increases of more than 40 percent.
