Shares of USANA Health Sciences (USNA) surged 18.30% in after-hours trading on Tuesday following the release of its impressive second-quarter 2025 financial results. The health and wellness company significantly outperformed analyst expectations, demonstrating robust growth and improved profitability.

USANA reported quarterly earnings of $0.74 per share, handily beating the analyst consensus estimate of $0.54 by 37.04%. This represents a substantial increase from the same period last year. The company's quarterly sales also exceeded expectations, coming in at $235.848 million, a 10.79% year-over-year increase and 4.73% above the analyst consensus estimate of $225.195 million.

The strong performance was attributed to USANA's comprehensive commercial strategy, which included enhanced sales incentives and refreshed brand messaging. Additionally, the company's direct-to-consumer business, Hiya, showed strong year-over-year growth with improved profitability, bolstered by a new partnership with Disney. Despite a decline in active customers across regions, USANA reiterated its full-year 2025 outlook, projecting net sales between $920 million and $1 billion, and adjusted diluted EPS between $2.35 and $3.00. This positive guidance, coupled with the company's debt-free status and ongoing share repurchase program, appears to have fueled investor optimism, leading to the significant after-hours stock price surge.
