PayPal Holdings Inc. shares dropped the most in more than a year after volume from former parent eBay Inc. tumbled and the payments giant lowered its guidance for revenue and earnings.

Transactions tied to eBay’s marketplace slid 45% in the third quarter, a bigger decline than in the previous three months, PayPal said in a statement. PayPal has been battling the loss of eBay ever since the two decided to end their longtime partnership in 2018.
