NEW YORK: PepsiCo. Inc. has raised its full-year earnings forecast and said snack sales helped its quarterly profit beat expectations, sending its shares up more than 1 percent.

The company, which makes Frito-Lay snacks and beverage brands like Mountain Dew and Tropicana, said its quarterly performance underscored how its beverage and snacks businesses worked well together.

Chairman and CEO Indra Nooyisaid Mountain Dew and Doritos chips were products that tended to be bought together in the US. Internationally, PepsiCo. was promoting its Lays and Pepsi brands jointly through ads and discounts, she said.

In developed markets, consumer demand “continues to be sluggish and in developing and emerging markets, there is continued macro and political volatility, most notably in Eastern Europe, the Middle East and a number of markets in Latin America,” Nooyi said.

The activist investor Nelson Peltz’s Trian Fund Management had recently urged the company to split its more successful snack division from its sluggish beverage business, to reduce costs and unlock value for shareholders.

PepsiCo. contended its current strategy was working and that it has exceeded analysts’ estimates for earnings per share for 11 quarters in a row.
