Wendy's (WEN) - Get Report  rose more than 4% Friday after CEO Todd Penegor said the burger chain's North American same-store sales rose 4.4% in the third quarter.

The return of Wendy's spicy nuggets helped to produce that increase, he said at the company's investment day Friday, according to CNBC. The company plans to report earnings Nov. 6.

Wendy's rose 4.23% to $20.84. Shares have risen about 35% year to date.

Wendy's said that the breakfast plan it announced last month will push breakfast sales to at least 10% total sales. The company struggled with prior attempts to break into breakfast, and analysts are skeptical about the latest effort, CNBC reported.

But Wendy's U.S. President Kurt Kane promised investors Friday that the company was building the latest program differently. He said Wendy's cooperated with franchisees to form the program. Company executives maintain that breakfast should be immediately profitable for franchisees.

Wendy's previous breakfast plans were regional, requiring local ad campaigns. This time around the company is going national, CNBC said.

Wendy's also is joining the trend toward meatless burgers, with a current test of black bean burgers. They could hit menus next year, Kane said. The company is looking at other meat substitutes too.

The fast-food chain said it hopes to raise digital sales to 10% of total U.S. sales by 2024, up from 2% now.
