The story of ExxonMobil begins not in 1999, when the modern corporation was formally created, but in Cleveland, Ohio in 1870, when a twenty-six-year-old produce merchant named John Davison Rockefeller incorporated the Standard Oil Company with his brother William, chemist Samuel Andrews, and a handful of partners. At the time, the American oil industry was barely a decade old, born of the 1859 discovery at Drake's Well in Titusville, Pennsylvania that crude oil could be extracted from the earth in commercial quantities and refined into kerosene — the fuel that lit millions of American homes in the era before electricity. The industry was chaotic, fragmented, boom-and-bust, and extraordinarily wasteful. Rockefeller believed, with the moral certainty of a man raised in the Baptist church and trained in the ledger books of commerce, that consolidation was not merely profitable but righteous — that eliminating the waste of competition would benefit consumers and the economy even as it made him fabulously wealthy.
Rockefeller's method was the horizontal combination — acquiring competitors through a combination of negotiation, financial pressure, and occasionally tactics that his critics described as coercive. By 1879, Standard Oil controlled approximately 90 percent of the United States' refining capacity and 90 percent of its oil pipelines, organized through a legal structure called a trust that allowed Rockefeller to coordinate the operations of nominally separate companies. The trust was reorganized as the Standard Oil Company (New Jersey) in 1882, and by the turn of the century, it had become the most powerful corporation in the world — and the most hated. Journalist Ida Tarbell's nineteen-part investigative series in McClure's Magazine, published from 1902 to 1904, documented the trust's competitive practices with meticulous detail and ignited a public and political firestorm that culminated in the Supreme Court's 1911 dissolution order under the Sherman Antitrust Act.
The Court's 1911 dissolution created 34 successor companies. The two most significant were Standard Oil of New Jersey, which retained the company's largest refining assets and the Esso brand, and Standard Oil of New York (Socony), which held much of the company's New York-area infrastructure and eventually became Mobil Oil. Over the following decades, both companies expanded aggressively internationally. Standard Oil of New Jersey entered into joint ventures with Shell and Anglo-Persian (later BP) to develop Middle Eastern oil, signed the famous Red Line Agreement that carved up Mesopotamia's petroleum resources among Western companies, and transformed into a global energy company that changed its brand name to Esso in the 1930s and ultimately to Exxon in 1972. Mobil, meanwhile, developed its own international presence, acquiring significant acreage in the North Sea in the 1960s and building a chemicals business that would become one of the most profitable in the industry.
By the 1990s, the oil industry landscape had been reshaped by three decades of OPEC price shocks, the nationalization of most Middle Eastern oil reserves, the development of North Sea and Alaskan production, and the persistent pressure of low oil prices in the mid-1980s. The Western oil majors faced a structural challenge: their reserve bases were declining, their cost structures were high relative to national oil companies, and the equity markets were rewarding companies that could demonstrate efficiency and earnings growth rather than merely production volume. The solution that industry leaders converged on was consolidation — massive mergers that would create companies with the scale, financial strength, and cost structures to compete in a world where oil prices might remain below 20 dollars per barrel indefinitely.
Lee Raymond, Exxon's chief executive, and Lucio Noto, Mobil's chief executive, announced the merger of their companies in December 1998. The transaction was valued at approximately 81 billion dollars and was, at that moment, the largest corporate merger in history. Regulatory approval required the divestiture of more than 2,400 Exxon-branded and Mobil-branded gas stations to prevent undue concentration in retail fuel markets, along with refineries and pipeline assets. The Federal Trade Commission approved the merger in November 1999, and ExxonMobil Corporation began trading on the New York Stock Exchange in December 1999 as the world's largest publicly traded oil company. The reunion of the two largest remnants of Standard Oil was complete — Rockefeller's empire had, in a sense, partially reassembled itself, now operating under the scrutiny of modern antitrust law and environmental regulation.
