08:00 AM EDT, 09/02/2025 (MT Newswires) -- Amazon.com's ( AMZN ) US Prime sign-ups fell short of last year's aggregate and the company's own targets, Reuters reported Tuesday, citing internal data.

The e-commerce giant registered 5.4 million US sign-ups over the 21-day run-up to Prime Day and its four-day sales event from July 8 through July 11, according to the report.

That was roughly 116,000 fewer than for the same period a year earlier and 106,000 below Amazon's ( AMZN ) own target, Reuters reported, citing the data.

The news agency said it was not able to determine how many days the company used in its calculation for the full 2024 period.

Amazon ( AMZN ) did not immediately respond to MT Newswires' request for comment.

The company's shares were down 1.4% in recent premarket activity.
