Amazon is now part owner of an aircraft-leasing company, according to new regulatory filings submitted on Friday.
They show Amazon owning 9.99% of Air Transport Services Group (ATSG), the company it agreed to lease 20 Boeing 767 wide-body freighter aircraft from last week.
ATSG saw its stock jump almost 5% in after-hours trading following the filing. Amazon wasn't immediately available for comment.
The ownership stake comes about a week after the deal between ATSG and Amazon was made public. As part of the deal, ATSG granted Amazon the right to buy up to 19.9% of its stock over the next five years.
The news is just the latest in a series of moves by Amazon that shows its wider ambitions at building its own in-house shipping and logistics service.
It recently registeredAmazon China as an ocean-freight forwarder and bought thousands of its own Amazon-branded trailer trucks, while calling itself a "transportation service provider" for the first time in its annual report.
