Mannatech Reports Financial Results for Third Quarter 2025

(Flower Mound, Texas) November 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 third quarter of 2025.

Third Quarter Results

• Net sales for the quarter ended September 30, 2025 were $29.2 million, as compared to $31.7 million for the same period in 2024, a decrease of $2.6 million, or 8.1%. On a Constant dollar basis (see Non-GAAP Measures, below) our net sales decreased $2.3 million, or 7.3%, 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, however sales for the third quarter of 2025 were higher than the first two quarters of 2025.

• Gross profit as a percentage of net sales increased to 76.4% for the three months ended September 30, 2025, as compared to 74.5% for the same period in 2024. The increase in gross profit as a percentage of net sales was primarily due to higher sales prices which was added in the third quarter of 2025 and lower inventory reserve additions compared to the same period in 2024. The timing of certain sales promotions also increased gross profit as a percentage of net sales during the quarter, compared to the same period in 2024.

• Commission expenses for the three months ended September 30, 2025 decreased by 10.7%, or $1.3 million, to $10.9 million, as compared to $12.2 million for the same period in 2024. Commissions are earned from sales. Commission expenses in dollar terms decreased during the three months ended September 30, 2025 primarily due to a decline in our sales. For the three months ended September 30, 2025, commissions as a percentage of net sales decreased to 37.5% from 38.3% for the same period in 2024.

• For the three months ended September 30, 2025, selling and administrative expenses decreased by $0.7 million, or 7.8%, to $9.1 million, as compared to $9.8 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, a $0.1 million decrease in travel and entertainment costs, a $0.1 million decrease in warehouse costs and a $0.1 million decrease in charitable contributions. Selling and administrative expenses, as a percentage of net sales, for the three months ended September 30, 2025 increased to 31.1% from 31.0% for the same period in 2024.

• Income from operations was $2.0 million for the three months ended September 30, 2025 as compared to $0.9 million in the same period last year.

• Income tax expense was $0.6 million for the three months ended September 30, 2025 as compared to income tax benefit of  $0.4 million in the same period last year.

• Net income was $1.9 million for the three months ended September 30, 2025, or $1.01 per diluted share, as compared to net loss of  $0.3 million, or $0.17 per diluted share for the three months ended September 30, 2024.

• As of  September 30, 2025, the Company's cash and cash equivalents decreased 37.3%, or $4.3 million, to $7.1 million from $11.4 million as of December 31, 2024.

Recruiting new associates and preferred customers decreased 21.9% in the third quarter of 2025 as compared to the third quarter of 2024.

Management's Statement

Changes in current trade policies, including with respect to tariffs, could affect our cost structure and profitability. While we take steps to mitigate or avoid these increased costs and disruptions, our ability to do so may be limited by operational and supply chain constraints and uncertainties, especially in the short term.

Non-GAAP Financial Measures

In addition to results presented in accordance with GAAP, this press release and related tables include certain non-GAAP financial measures, including a presentation of Constant dollar measures. 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.

The Company believes that these non-GAAP financial measures provide useful information to investors because they are an indicator of the strength and performance of ongoing business operations. The constant currency figures are financial measures used by management to provide investors with an additional perspective on trends. Although management believes the non-GAAP financial measures enhance investors’ understanding of their business and performance, these non-GAAP financial measures should not be considered an exclusive alternative to accompanying GAAP financial measures. Please see the accompanying table entitled "Non-GAAP Financial Measures" for a reconciliation of these non-GAAP financial measures.

Non-GAAP Financial Measures (Sales, Gross Profit and Income from Operations in Constant Dollars)

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.

The tables below reconcile third quarter 2025 and year-to-date Constant dollar net sales, gross profit and income from operations to GAAP net sales, gross profit and income from operations. (in millions, except percentages):
