In its 2021 annual report, WEX estimated that every time gas prices fluctuate one penny, it impacts revenue by $1.5 million. Moreover, WEX management recently laid out a five-year plan to grow revenue at a 10% to 15% compound annual rate going forward. However, WEX (NYSE: WEX) is an under-the-radar stock that could actually benefit from rising gasoline prices and is therefore worth considering right now.
