Herbalife Ltd. reported declines in second-quarter revenue and earnings, hurt in part by the stronger dollar, but shares surged in after-hours trading as results still surpassed expectations and the nutritional-products company raised its outlook for the year.

The company now expects full-year 2015 per-share earnings of $4.50 to $4.70, compared with its previous estimate of $4.30 to $4.60.

Shares rose 6.9% to $52.50 in after-hours trading.

Herbalife, based in the Cayman Islands, sells a range of products, including weight-loss shakes and fitness supplements, operating through a global network of independent distributors.

The company has been embroiled in a public battle with Pershing Square Capital Management LP's William Ackman, who has attempted to convince other investors that Herbalife is a pyramid scheme, accusations the company has denied. The company's shares have been volatile since Mr. Ackman first disclosed a billion-dollar bet against the company in December 2012.

In the latest quarter, volume fell in all regions except China and EMEA, where volumes increased 38% and 4%, respectively. World-wide volume fell 5%.

Overall, the company reported earnings of $82.8 million, or 97 cents a share, compared with year-earlier earnings of $119.5 million, or $1.31 a share. Excluding items, per-share earnings fell to $1.24 from $1.55 a year earlier.

Sales dropped 11.5% to $1.16 billion, hurt in part by the stronger U.S. dollar.

Analysts polled by Thomson Reuters expected $1.11 a share on $1.14 billion in revenue.
