NEW YORK — Darden Restaurants wants to set Red Lobster adrift.

The company said Thursday that it is looking to either spin off or sell Red Lobster as part of its plan to boost value for its shareholders. Those plans also include suspending the opening of new Olive Garden locations and limiting the launch of new LongHorn Steakhouse restaurants.

Darden Restaurants Inc. also won’t make any acquisitions of additional brands “for the foreseeable future” and will review senior management’s compensation and incentive programs to put greater emphasis on same-store restaurant sales growth and free cash flow.

Red Lobster has 705 restaurants in the U.S. and Canada and is the biggest full-service-dining seafood specialty restaurant operator in North America. Its fiscal 2013 sales were about $2.6 billion.

Restaurant chains such as Olive Garden and Red Lobster have suffered since the Great Recession, with customers being more careful about their spending. People are also increasingly heading to chains such as Chipotle, where food tends to cost less and the experience takes less time than a sit-down meal.

Darden Chairman and CEO Clarence Otis said during a conference call Thursday that Red Lobster has been unable to capture high-income customers as much as its other brands have. A separation will give Red Lobster the opportunity to focus more on its core audience. He also said changing market conditions prompted action, noting the “relatively low levels of consumer demand in each of the past several years for restaurants generally, and for casual dining in particular.”
