MILWAUKEE (AP) -- Bearing in mind that consumers will remain focused on low prices even when the recession ends, soft drink and snack maker PepsiCo Inc. said Thursday that it's creating new products at lower prices and plans to continue offering discounts in its Frito-Lay and beverage businesses.

The effort seems to be working for PepsiCo's Plano, Texas-based Frito-Lay business, which posted revenue and volume gains in the third quarter. But the beverage business, with brands like PepsiCola, continued to slump as consumers cut their spending and continued switching to healthier juices and teas.

Overall, the Purchase, N.Y.-based company said its fiscal third-quarter profit rose 9 percent, thanks in part to cost-cutting, even as revenue slipped 1 percent.

Chief Financial Officer Richard Goodman said PepsiCo has been offering more promotions at the end of each month, when consumers' budgets become more constrained. For instance, bags of chips may be promoted at two for $5 early in the month but fall to $2 each by the end of the month.

"We want to be able to make sure that at the beginning of the month or at the end of the month, they're buying our products," Goodman told reporters in a conference call after the company released its earnings report Thursday.

Consumers are so focused on cost they are willing to forgo getting more for a given price. PepsiCo's promotion to boost volume -- with no price increase -- on certain chips failed to gain traction and will be phased out, Goodman said.

Companies in all consumer categories are offering more discounts amid the recession, and they have to be careful not to let that eat into their profits, said Edward Jones analyst Jack Russo. Food companies are able to do this because their ingredient costs have fallen. Russo warned that consumers will keep expecting discounts for a long time.

"The challenge is, once you give them a really good deal, so to speak, they'll be expecting that a lot more often," he said. "That's the challenge for these companies, getting in the promotional and discounting game but not getting too crazy with promotions."

He said PepsiCo's performance was strong in the quarter and the company was not doing too many promotions.

PepsiCo earned $1.72 billion, or $1.09 per share, in the three months that ended Sept. 5. That's up from the $1.58 billion, or 99 cents per share, a year earlier.

The profit beat the average expectation of analysts polled by Thomson Reuters, whose estimates typically exclude one-time items; they forecast profit of $1.03 per share.

But sales slipped 1 percent to $11.08 billion from $11.24 billion, falling short of Wall Street's $11.25 billion estimate.

Shares fell $1.05 to $60.12 in midday trading Thursday.

PepsiCo's Americas Beverages unit reported a 6 percent drop in volume and a 9 percent revenue decline, while Frito-Lay North America had a 3 percent rise in volume and 5 percent revenue boost. Quaker Foods North America also posted revenue gains.

Food makers in general have benefited during the recession as strapped consumers eat at home more to save money.

PepsiCo saw strength abroad, as sales grew at PepsiCo's International and Asia, Middle East and Africa divisions.

Costs fell faster than revenue at the company overall, with selling, general and administrative expenses down 8 percent to $3.65 billion.

PepsiCo expects its $7.8 billion buyout of its two largest North American bottlers to close by the end of 2009 or early 2010.

PepsiCo reaffirmed its guidance for fiscal 2009 that earnings per share will grow by a percentage in the mid-to-high single digits, if currency stays constant. For fiscal 2010, PepsiCo targets earnings per share growth of between 11 percent to 13 percent, with currency staying constant.
