Exxon Mobil Corporation reported a $3.4 billion writedown related to its Sakhalin-1 operation in Russia, resulting in a 1.3% drop in stock price. The company posted mixed quarterly results with revenues at $90.5 billion but earnings per share of $2.07, missing expectations. Despite these challenges, Exxon plans to triple its share buyback program to $30 billion by the end of 2023, aiming to bolster shareholder value in a turbulent economic climate.
