(Flower Mound, Texas) August 12, 2025 - Mannatech, Incorporated (NASDAQ: MTEX), ("Mannatech" or "Company"), global health and wellness company committed to transforming lives to make a better world, today announced financial results for its second quarter of 2025.

•Net sales for the quarter ended June 30, 2025 were $25.7 million, as compared to $27.7 million for the same period in 2024, a decrease of $2.1 million, or 7.4%. On a Constant dollar basis (see Non-GAAP Measures, below) our net sales decreased $1.8 million, or 6.5%, and unfavorable foreign exchange caused a $0.2 million decrease in GAAP net sales as compared to the same period in 2024.The decline in revenues was principally due to slowing demand in certain regions we operate within due to weakened economic conditions, relative to the prior year

•Gross profit as a percentage of net sales decreased to 73.6% for the three months ended June 30, 2025, as compared to 77.1% for the same period in 2024, some of the increase in costs were related to increased freight costs related to back ordered items and running sales promotions on products thereby reducing our gross profit margin.

•Commission expenses for the three months ended June 30, 2025 decreased by 14.4%, or $1.6 million, to $9.5 million, as compared to $11.1 million for the same period in 2024. Commissions are earned from sales. Commission expenses in dollar terms decreased during the three months ended June 30, 2025 primarily due to a decline in our sales. For the three months ended June 30, 2025, commissions as a percentage of net sales decreased to 37.0% from 40.0% for the same period in 2024.

•For the three months ended June 30, 2025, selling and administrative expenses decreased by $0.1 million, or 0.8%, to $10.8 million, as compared to $10.9 million for the same period in 2024. The decrease in selling and administrative expenses was the result of a $0.4 million reduction in payroll costs, which was offset by a $0.2 million increase in marketing costs and a $0.1 million increase in office expenses. Selling and administrative expenses, as a percentage of net sales, for the three months ended June 30, 2025 increased to 42.0% from 39.1% for the same period in 2024.

Changes in current trade policies, including with respect to tariffs, could affect our cost structure and profitability.

The company discloses operating results that have been adjusted to exclude the impact of changes due to the translation of foreign currencies into U.S. dollars, including changes in: Net Sales, Gross Profit, and Income from Operations.

CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS - (UNAUDITED)

Net sales by region for the three and six months ended June 30, 2025 and 2024 were as follows (in millions, except percentages):

To supplement its financial results presented in accordance with generally accepted accounting principles in the United States (“GAAP”), Mannatech discloses operating results that have been adjusted to exclude the impact of changes due to the translation of foreign currencies into U.S. dollars, including changes in: Net Sales, Gross Profit, and Income from Operations. It refers to these adjusted financial measures as Constant dollar items, which are non-GAAP financial measures. The company believes these measures provide investors with an additional perspective on trends. To exclude the impact of changes due to the translation of foreign currencies into U.S. dollars, it calculates current year results and prior year results at a constant exchange rate, which is the prior year’s rate. Currency impact is determined as the difference between the actual GAAP results and the recalculated results for the current year at the Constant dollar rates.
