The company said the new menu, which included social media favorite the "Baconator sandwich", had a strong second quarter, at a time when other chains such as McDonald's and Starbucks have said they are facing pressure as people working from home are increasingly cooking their meals.

"Despite breakfast being the hardest hit daypart in QSR (quick service restaurants category) since the beginning of the pandemic, our businesses continue to grow each month," Wendy's Chief Executive Officer Todd Penegor said.

Decline in the U.S. same-store sales in the second quarter was limited to 4.4% by a recovery towards the end of the quarter. In July, sales rose 8.2%, after a 5.1% growth in June.

Truist Securities analyst Jake Bartlett said the current trends give confidence that Wendy's will "continue to thrive despite the COVID-19 crisis and quickly re-accelerate."

The company also said it would invest $13 million more in the breakfast category, launched in March in the hopes of gaining customers from McDonald's, in the back half of the year.

Excluding items, Wendy's earned 12 cents per share in the second quarter ended June 28, scraping past estimates of 11 cents per share, according to IBES data from Refinitiv.

Shares of the chain, up 7% this year, were down 4% in early trading as limited restaurant operations due to the pandemic dented sales in the quarter.

Revenue fell about 8% to $402.3 million, missing estimates of $409.7 million.

Wendy's also said on Wednesday it intended to resume share repurchases in 2020 after suspending it in March to conserve cash amidst declining sales.
