Seaport Global analyst Kevin Sterling commented on news Aegean Marine (ANW), World Fuel Services' primary competitor in the marine fuel logistics segment, will have to write off $200M of accounts receivables owed to the company. Sterling views this as a "crippling blow" to Aegean Marine as selling bunker fuel is a working capital-intensive business, with receivables being the lifeline and major asset of the company. The analyst said Aegean is "severely weakened" and World Fuel has an opportunity to pick up additional market share, combined with the potential for pricing to have an upward bias.
