A tiny hedge fund dealt a major blow to Exxon Mobil Corp on Wednesday, unseating at least two board members in a bid to force the company¡¯s leadership to reckon with the risk of failing to adjust its business strategy to match global efforts to combat climate change.

The success by hedge fund Engine No. 1 in its showdown with Exxon shocked an energy industry struggling to address growing investor concerns about global warming. It happened on the same day activists scored a big win against another oil major, Royal Dutch Shell ¡ª a Dutch court ordered the company to drastically deepen pledged cuts to greenhouse gas emissions.

Eight of Exxon¡¯s nominees including CEO Darren Woods were re-elected to its 12-member board of directors, along with two of Engine No. 1¡¯s nominees, the company said. The counting is not finished, so Engine No. 1 could potentially see three of its four nominees join the Exxon board.
