Herbalife Ltd. released their second-quarter report on Monday with results that missed the target of analysts.

The adjusted earnings reported by the company was US$0.01 per share short of the forecasted amount.

Herbalife managed to top Wall Street's estimates for 21 consecutive quarters since 2008, but the after-hours trading on Monday showed that the company's shares fell US$60.95 or 9.7 percent.

The net sales growth reported by the company was below the target and the third-quarter per-share earnings forecast missed analysts' estimates.

The company released an estimated per share earnings of US$1.49 to US$1.53 and a net sales growth of 9 percent to 11 percent, for the third quarter.

However, the company raised the target to US$6.17 to US$6.32 for the per-share earnings and 8.5 percent to 10.5 percent for the net sales growth.

In a statement, Herbalife CEO Michael O. Johnson showed a positive outlook regarding the company's earnings.

Johnson said in a news release that Herbalife showed strong results in sales and profitability as it established the ability to increase the earnings every year, according to the Los Angeles Times,

"Our performance is a testament to the enthusiasm our millions of consumers and members have for our products," Johnson said.

In 2013, Herbalife reported a profit of US$143.2 million or US $1.34 a share, but in 2014, the profit reported by the company fell by 16 percent to US $119.5 million or US $1.31 per share.

Meanwhile, Wall Street has been keeping an eye on Herbalife after Pershing Square Capital Management LP's William Ackman accused the company of pyramiding in 2012.

Ackman said he would carry a "deathblow" to the company.

Herbalife's shares decreased by 11 percent last week following Ackman's claims of having new evidence to prove that the nutrition company is siphoning the money of people it recruits.

However, investors shrugged the allegations when investigations came up without substantial evidence to prove Ackman's claim, which resulted in Herbalife's stock to rise to 25 percent the next day.
