(Reuters) - Shares of U.S. auto part retailers fell sharply on Monday following a report that Amazon.com Inc (AMZN.O) had set its sights on the $50 billion do-it-yourself after-market auto parts business.
Shares of Autozone Inc (AZO.N), which has a comparatively bigger exposure to the retail auto parts market, slumped as much as 5.1 percent to $730.99, posting their biggest intraday percentage loss in nearly one year.
Advance Auto Parts Inc's shares (AAP.N) fell 4.2 percent to $164.27, O'Reilly Automotive Inc (ORLY.O) declined 4 percent to $263.13 and Genuine Parts Co (GPC.N) lost 3.7 percent to $96.
Amazon has struck supply contracts with some of the largest parts makers including Federal-Mogul Holdings Corp (FDML.O), Dorman Products Inc, Robert Bosch GmbH and Cardone Industries Inc, NY Post reported on Sunday, citing sources. (http://nyp.st/2k8Ibhq)
The NY Post report implies that Amazon is both paying vendors more and offering customers lower prices than brick-and-mortar competitors on like-for-like products, according to RBC Capital Markets analyst Scot Ciccarelli.
Northcoast Research analyst Nick Mitchell estimated that about 75 percent of Autozone's sales come from the retail auto parts or the do-it-yourself market targeted by Amazon.
The market accounts for low-50 percent of the sales mix for O'Reilly, low-40 percent for Advance Auto Parts and about 15 percent for Genuine Parts, Mitchell said.
Amazon, the world's largest online merchant, is known for disrupting traditional brick-and-mortar businesses.
The company is expected to surpass Macy's Inc (M.N) to become the No.1 U.S. apparel retailer in 2017, according to a report published by Cowen & Co in October.
However, analysts played down any immediate impact to auto part retailers from Amazon's entry.
"If Amazon is committed ... they are definitely going to pick up some share. In terms of the disruption they will cause, I don't think it will happen as quickly," Mitchell told Reuters.
Ciccarelli said Amazon's reach will be relatively limited in scope as most retail customers likely don't have the information and skill sets needed to comfortably order parts on their own.
For Amazon, the push into auto parts is seen as the next step to growing its auto business, Amazon Vehicles, an online platform for users to research on cars, auto parts and accessories, which it launched in 2016.
"Longer-term, this push into autos ... also sets the table for Amazon to potentially grow into the materially larger new and used car buying market too," Morgan Stanley analyst Brian Nowak wrote in a note.
