It looks like America may be running a little bit less on Dunkin’.

Dunkin’ Brands Group, facing increased competition for consumers’ breakfast dollars, on Thursday suffered its worst stock decline, 12.2 percent, since the Canton-based company went public in 2011.

The stock had gained 15 percent this year through Wednesday, but it slid on Thursday, ending the day at $43, only slightly above where it was when the year began.

That happened after Dunkin’ Brands stuck with an annual profit forecast that fell short of what analysts had estimated.

Repeating a forecast that it first gave in April, Dunkin’ Brands said Thursday that earnings this year will be $1.87 to $1.91 a share, excluding some items.


Analysts had estimated $1.92, on average, according to a poll by FactSet. Analysts also expected revenue to rise about 8 percent to $808.1 million.

Revenue, Dunkin’ said, will grow 6 to 8 percent from the previous year.

US same-store sales at Dunkin’ Donuts increased by about 1.1 percent in the third quarter, the company said — a slowdown from the 2.9 percent gain in the prior quarter.

To simplify operations, the chain recently took some of its Coolatta frozen drinks off the menu to focus on new smoothies and other beverages. The move backfired, and Dunkin’ will probably bring back those drinks next year, chief executive Nigel Travis said.

Dunkin’ Donuts is facing more competition from fast-food chains, including Taco Bell, that are now selling breakfast fare. Dunkin’ does more than 60 percent of its business before noon, meaning that it’s especially vulnerable as other chains maneuver for a piece of the breakfast market. Afternoon and evening sales could boost Dunkin’s fortunes.

And while Dunkin’ has said that its rewards program is helping to propel sales, it still trails Starbucks Corp.’s loyalty program, which boasts about 10.4 million active US members.


But if you hate break-room coffee — and Dunkin’ is hoping that you do — you may soon be able to have Dunkin’ Donuts coffee delivered.

In a presentation to investors posted on Thursday, the company said it will test a delivery service as soon as this month in Dallas.

It’s unclear when deliveries might be available in Massachusetts. The company squashed a delivery agreement between the service Foodler and one of its Boston franchisees last year, according to Boston.com.

In the meantime, there are unofficial ways to get Dunkin’ delivered. Favor, which charges $5 per delivery, has a Dunkin’ menu on its website . You can also get Starbucks products delivered by using the website Postmates.

Dunkin’ said any delivery options will be integrated into its app at some point. The company said it’s “exploring third-party options” for deliveries — a slide that was part of its presentation to investors on Thursday displayed the logos of Doordash and Favor — but Dunkin’ did not respond to a request for comment about its delivery arrangements or possible timeline.

Also on Thursday, Dunkin’ Brands, which also owns Baskin-Robbins, said 100 counters in Speedway gas stations run by Dunkin’ franchisees will be closed. Dunkin’ said the locations represent just 0.1 percent of its revenue, and the closings could give franchisees opportunities to open full restaurants in the same areas. Another 500 locations in which Speedway itself is the franchisee will remain open.

Franchisees, which operate nearly all stores, are concerned about rising minimum wages and are raising menu prices, Travis said on an investor webcast Thursday. A tighter labor market is also making it harder to hire restaurant workers, he said.

Dunkin’ Donuts has about 8,200 US locations; Baskin-Robbins has 2,400.
