Herbalife Ltd. (HLF) experienced a significant surge in its stock price during post-market trading, with shares soaring 11.06%. The dramatic movement followed the simultaneous release of the company's fourth-quarter financial results and a major strategic announcement.

Herbalife posted adjusted earnings per share of $0.45, beating the consensus estimate. Quarterly sales reached $1.283 billion, also surpassing estimates and representing a year-over-year increase.

Second, Herbalife announced that global football icon Cristiano Ronaldo has invested $7.5 million in the company's Pro2col™ personalized nutrition technology, acquiring a 10% equity stake in the related software subsidiary. This high-profile endorsement and investment signal strong confidence in Herbalife's technological innovation and growth prospects in the personalized nutrition sector.
