Starbucks tempered disappointing earnings news on Wednesday with a raft of product launch announcements, the latest in a series of measures to breathe life into the struggling brand.

Speaking on a conference call after the close of trading, C.E.O. Howard Schultz laid out three (not yet named) chilled beverage initiatives focused around the health and wellness category.

The first will be Starbucks' debut in energy beverages, a market that Schultz estimates at $4.4 billion and growing at 31 percent annually. Starting this summer the coffee chain will launch an extension of Doubeleshot, a canned espresso-based drink available at Starbucks stores and at other retailers.

"Entering this category offers us a significant opportunity for us to compliment our customers lifestyle and engage in important and relatively untapped demo for Starbucks," Schultz said on the call.

Energy drinks will be customizable in Starbucks stores and available elsewhere through a joint venture with Pepsi, which currently markets Doubleshot and Frappuccino beverages in association with Starbucks.

The other two new beverages—a low-calorie protein and fruit smoothie and a frozen concoction similar to a Frappuccino—were revealed in the Wall Street Journal earlier Wednesday.

Starbucks said the smoothie will be initially available in two flavors this summer. The Frappuccino-like product, which will be made in partnership with an Italian supplier, will have "options ranging from fruit based, to dairy based, to yogurt based ingredients." That new beverage will be introduced in Southern California.

Schultz also spoke vaguely about plans for "nutritious" food items in stores, the first of which will arrive in September. The company said earlier in the year that it would stop selling warm breakfast sandwiches.

"We are highly committed to the health and wellness category and see this as an important long term growth area for the company," said Schulz.

Wednesday's product launch announcements came amid news of a disappointing 28 percent drop in quarterly profit for the company, and plans to further cut U.S. store openings.

Starbucks had second-quarter net income of $108.7 million, or 15 cents per share, compared with $150.8 million, or 19 cents per share, a year earlier.

In advance of last week's profit warning by the company, analysts had been looking for a second-quarter profit of 21 cents per share.

Revenue rose 12 percent to $2.53 billion. But U.S. same-store sales fell on a percentage basis due to a weakening consumer environment.

Starbucks plans to open fewer than 400 new U.S. stores annually for the next three fiscal years.
