Dear Shareholders, We would like to thank you, our valued shareholders, for your continued support of USANA’s mission, which is centered on improving the health and wellness of individuals and families to create the healthiest family on earth. The following objectives are key to accomplishing this mission: 1. Providing the highest-quality and best-in-class nutritional products to our customers around the world. 2. Growing our worldwide business by emphasizing active customer growth. 3. Offering an excellent customer experience. 4. Enhancing our global sustainability efforts by giving back through the efforts of employees, customers, and the USANA Foundation. Fiscal 2024 Results Full year operating results reflected continued, cautious consumer sentiment in many of our key Asia Pacific markets. This created a challenging environment to attract new customers and generate positive momentum throughout the year. Notwithstanding these factors, our commercial team made progress on several meaningful initiatives, which will begin rolling out across our direct sales business this year. We are confident these initiatives will lay the foundation for the Company to generate long-term growth. Repositioning for Future Growth During 2024, we pivoted to better address this dynamic operating environment by reorganizing our sales, marketing, and communications departments into one commercial team. We believe this has better positioned us to execute our customer growth strategy in 2025, which is centered on our ability to deliver three fundamental benefits to our sales force: (1) best-in-class products, (2) a simple brand message that highlights the superiority, differentiation, and benefits of these products, and (3) an income opportunity that is simple, rewarding, and worthy of our Associates' time and effort. Accordingly, our commercial team is comprised of three core global teams: Product, Brand, and Opportunity, as well as our regional and local business units. We saw notable and tangible benefits from the commercial team in 2024, including the launch of our Celavive Resurfacing Serum and Whey Protein Isolate products. These product launches are illustrative of the early stages of our product innovation strategy, which includes increasing the cadence of new and upgraded high-quality, relevant, and premium products. We also completed our acquisition of Hiya Health in the fourth quarter, which is a meaningful milestone for USANA and an exciting addition to our business. Hiya is a growing, highly cash generative, direct-to-consumer children’s wellness brand. Hiya has an experienced management team that continues to lead the company and a compelling subscription business model we believe is positioned to deliver long-term sustainable growth over the next several years. We look forward to supporting Hiya as they build upon their leadership position in the children’s health and wellness market. Enhancing the Experience Providing the best customer experience and increasing the number of active customers in our business continue to be our top priorities, and in 2025 we plan to execute on the following strategies to accomplish our goals: • A higher cadence of new product launches and improved existing products tailored to local markets. • Strategic enhancements and modifications to our Associate incentive offering, which are intended to incent customer growth and improve pay for performance. • Strengthening our brand messaging, story, and value proposition; and • Accelerating Associate engagement activities in our regions around the world. Giving Back The USANA Foundation, which is the charitable arm of our business, continued to fulfill its mission of providing immediate and long-term global food relief for those in severe need. The foundation carries out its mission by leading a network of community-driven partnerships to nourish those in need, equip individuals to better nourish themselves, and help eliminate hunger throughout the world. In 2024, the USANA Foundation provided, among other things: • Over 30 million meals. • Aid and grants to partner charities around the world. • Backpacks of food for at risk children in local schools to take home on the weekend and during long holiday breaks; and • Children's vitamins to some of the most malnourished children around the world. Our team is proud of the positive impact we are having around the world. We are improving individuals’ health through our exceptional health products, improving the financial health of our Associates through our business offering, and offering help to those in need through our charitable efforts. I am confident we will have an even larger impact as we continue to execute on our strategies to strengthen and grow our global business. We thank our customers, Associate sales force, employees, and other stakeholders for their significant contributions to this mission.

Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control.

PART I Item 1. Business General USANA Health Sciences, Inc. is a global direct selling and direct-to-consumer nutrition, personal health and wellness company. In 2024, we generated $855 million in net sales and finished the year with approximately 454,000 direct selling active Customers. We were founded in 1992 by Myron W. Wentz, Ph.D. and since that time, we have developed and manufactured high quality, science-based nutritional, personal care and skincare products with a primary focus on promoting long-term health and wellness. We are committed to continuous product innovation and sound scientific research. We have operations in 25 geographic markets worldwide. Historically, we have distributed our products through the direct selling channel, because we believe it is conducive to our vision of improving the overall health and nutrition of individuals and families around the world. In December 2024, we acquired a 78.85% ownership interest in Hiya Health Products, LLC ("Hiya"), a leading direct-to-consumer provider of high-quality children's health and wellness products (the "Hiya Acquisition"). We believe that the addition of Hiya to our business promotes our vision and adds a diversified layer of growth in the direct-to-consumer channel. Consequently, we now operate and sell products through both direct selling and direct-to-consumer channels. Mainland China (“China”) is our largest direct selling market and single largest source of revenue, representing approximately 48.4% of net sales and approximately 50.2% of direct selling active Customers. As a U.S.-based multi- national corporation with an expanding international presence, our operating results are sensitive to currency fluctuations, as well as economic and political conditions in markets throughout the world. Additionally, we are subject to the various laws and regulations in the United States, China, and the other markets in which we operate with respect to the products that we manufacture, and sell, and our method of distribution. We are a U.S. public company listed on the New York Stock Exchange ("NYSE") and subject to the rules of the SEC. This “Item 1. Business” provides detailed information about our world-wide business, including who we are, what we do and where we are headed. Unless otherwise specified, current information reported in this Annual Report on Form 10-K for the fiscal year ended December 28, 2024 (this “report” or “Annual Report”) is as of or for the fiscal year ended December 28, 2024. We also discuss the development of our company and the geographic areas where we do business. For the year ended December 28, 2024, other than the Hiya Acquisition, there were no material changes to our corporate structure or our method of conducting business. Our Business We organize our business into two reportable segments: Direct selling and Hiya direct-to-consumer. Direct selling: The customer base for our direct selling segment is primarily comprised of two types of customers" "Associates" and "Preferred Customers" referred to collectively as "active Customers." Our Associates also sell our products to retail customers. Associates share in our company vision by acting as independent distributors of our products, in addition to purchasing our products for their personal use. In 2023, we launched our Affiliate program in the United States, Canada, and Mexico and are evaluating introducing the program in other markets. This program offers another sales and compensation opportunity to individuals who are interested in selling USANA products. Affiliates are discussed and reported in this report as part of our Associates. Preferred Customers purchase our products strictly for personal use and are not permitted to resell or to distribute the products. We only count as active Customers those Associates and Preferred Customers who have purchased from us at any time during the most recent three-month period. Hiya direct-to-consumer: The customer base for our Hiya direct-to-consumer segment is primarily comprised of customers purchasing Hiya products for personal use through a subscription model, which is intended to provide a steady, predictable income stream. The ongoing nature of subscriptions fosters stronger relationships with customers by making it easier for them to receive products regularly, which leads to strong retention and loyalty. Hiya's subscription model also provides rich data on customer preferences and behaviors, which enables personalized offerings, efficient marketing and data-driven innovation insights. Other: The customer base for our "other" category is comprised of customers of Rise Bar Wellness, Inc. ("Rise") and Oola Global, LLC "(Oola"), which are both businesses we acquired in 2022. Rise manufactures and sells high-quality protein bars and powdered drinks that are formulated to help customers achieve their health goals through clean and simple ingredients. Oola is a direct selling company that offers a personal development framework and nutritional products that helps individuals create a life of balance, growth, and purpose. 3

For more information relating to our reportable segments, see Note M to our consolidated financial statements. Current Focus and Growth Strategy In 2025, we will continue executing on our global Associate-first growth strategy with a strong focus on increasing the number of active Customers in each of our markets. Our key priorities include: (i) enhancing the earning opportunity of our Associates by refining our compensation plan to prioritize sales, customer growth, and team building; (ii) accelerating the launch of new and upgraded products while driving innovative product development; (iii) strengthening our brand messaging to create a more compelling and consistent market presence; (iv) deepening engagement with our Associates through both in-person and digital initiatives around the world; (v) focusing on China while also implementing more tailored, decentralized solutions to meet the unique needs of each region; and (vi) supporting and expanding our acquired businesses, including the growth of our Hiya direct-to-consumer business. Further details on these strategies are outlined below. Enhancing the Earning Opportunity To enhance the earning opportunity for our Associates, we are refining our compensation plan to better reward sales, customer growth, and team building. Our approach includes optimizing incentives to drive sustainable income, introducing targeted elements that reward sales, customer, and team growth early in the journey of a new Associate, and providing a more robust system of training, tools, and data to help Associates build and scale their businesses. By aligning our compensation structure with business growth objectives, we aim to create a more rewarding and financially empowering opportunity for our global Associate base. Product Development In 2025, we will strengthen our leadership in cellular nutrition by enhancing our core foundational and flagship products, developing more potent, unique, and differentiated formulations, and accelerating our speed to market for innovative new products. Our three dedicated product teams will continue to focus on delivering world-class nutrition solutions that meet evolving consumer needs and set new standards in the industry. Through continued investment in research, development, and cutting-edge science, we will ensure that USANA remains at the forefront of clinical nutrition, providing products that support optimal health and wellness worldwide. Strengthening our Brand We are enhancing and refining our brand messaging to create a more compelling, consistent, and globally recognized identity. Our focus is on clearly communicating our unique and differentiated commitment to world-class cellular nutrition, the strength of our science-backed products, and the life-changing opportunities we offer through our business model. We will continue to elevate our brand presence across digital and traditional channels, ensuring that our messaging resonates with both new and existing customers. By sharpening our positioning and storytelling, we aim to deepen trust, increase brand loyalty, and further differentiate USANA in the health and wellness industry. Associate Engagement We are deepening our engagement with Associates worldwide by enhancing both in-person and digital interactions. Our goal is to create a more connected and empowered health community by providing better communication, more personalized support, and expanded training opportunities. We will continue investing in digital tools, events, and mentorship programs that help Associates build successful businesses and foster stronger relationships within their teams. By prioritizing engagement at every level, we aim to strengthen the Associate experience, increase retention, and drive long-term growth across all markets. China and Regional Support We will continue executing strategic initiatives to drive growth in China, including: targeting and expanding a new customer demographic through simple, easy-to-use, digitally-based customer acquisition, fulfillment, and service initiatives; enhancing our digital capabilities with continued investments aimed at improving the overall customer experience; expanding our market-leading training, development, and certification programs to empower Associates in 4

health, business, and personal growth, ensuring they have the tools needed to succeed; and enhancing our product portfolio with products specifically designed for the Chinese consumer. Beyond China, we are strengthening our regional approach by empowering local leaders to develop winning strategies tailored to their unique cultures and market conditions. By providing them with greater authority and influence over product development and incentive creation, we are fostering a more agile, market-responsive organization. In India, following our market entry at the end of 2023, we continue to execute our long-term growth strategy by expanding our product portfolio, strengthening local marketing efforts, and supporting our Associates with enhanced tools and training. Additionally, we remain committed to evaluating new international markets for potential expansion, ensuring sustainable global growth for USANA. Acquired Businesses͏ In 2025, we plan to continue to support and grow our acquired businesses, including Hiya. Hiya expands our growth potential into the direct-to-consumer channel through Hiya's customer subscription model. Future Hiya growth initiatives include: (i) product portfolio expansion, (ii) distribution channel expansion, via other online marketplaces and select retail partners, and (iii) geographic expansion through leveraging USANA's expertise to expand into new markets. Over the next several years, USANA and Hiya will work together to capitalize on identified synergies, assets and expertise across both companies to promote overall sales and customer growth. We also intend to continue to utilize USANA's assets and resources to grow Rise and Oola and leverage their knowledge, experience, and technology to grow USANA’s core business. We also expect to continue to pursue acquisition opportunities in the health and wellness space that strengthen, diversify, and grow our world-wide business by focusing on: (i) overall nutrition, (ii) vertical integration, (iii) product and category expansion, distribution channel expansion, and (iv) geographic expansion.

Markets included in each of these sub-regions are as follows: (i) Greater China - Hong Kong, Taiwan, and China. Our business in China is conducted by BabyCare (ii) Southeast Asia Pacific – Australia, New Zealand, Singapore, Malaysia, the Philippines, Thailand, Indonesia, and India(1) (iii) North Asia – Japan and South Korea Americas and Europe (2) Americas and Europe – United States, Canada, Mexico, Colombia, and Europe (the United Kingdom, France, Germany, Spain, Italy, Romania, Belgium, and the Netherlands) (1) We commenced operations in India near the end of the fourth quarter of 2023 Hiya operates and sells products in the United States and may pursue geographic expansion into additional markets as a growth strategy in the future. Impact of Foreign Currency Exchange Rates Because we have operations in multiple markets, with sales and expenses generated and incurred in multiple currencies, our reported U.S. dollar sales and earnings can be significantly affected by fluctuations in currency exchange rates. In general, our operating results are affected positively by a weakening of the U.S. dollar and negatively by a strengthening of the U.S. dollar. In 2024, net sales outside of the United States represented approximately 89.3% of consolidated net sales. 7

Research and Development As a critical driver of our competitive advantage in the global nutritional supplement industry, we focus our research and development (“R&D”) efforts on developing and bringing to market high quality, science-based products that promote long-term health and wellness. Scientific innovation and rigorous product development enable us to deliver differentiated, high-quality products. Our R&D activities include identifying emerging trends, investigating new ingredients, developing products that are new to USANA and to the industry, and updating existing USANA-brand formulas to keep them current with the latest science and regulations in global markets, all of which ensure products are optimized to meet the changing, diverse needs of our global customer base. Our team is composed of scientists experienced in human nutrition, cellular biology, biochemistry, genetics, the microbiome, natural product chemistry, foods and cosmetic science, clinical research, and product development. Through strategic collaborations with academic institutions, independent research organizations, and healthcare professionals, along with reviewing the latest research on nutrition at scientific conferences and in journals, they work to identify possible new ingredients and product upgrade opportunities. As well, we employ experts in quality assurance, quality control, and global regulatory affairs in order to manage the entire product development lifecycle. These teams work in close partnership to ensure products are consistent, safe, and compliant with international regulations. When developing and manufacturing our products, we follow the highest applicable industry quality standards across all stages of product development and manufacturing. Our ingredients are selected to ensure purity, potency, and efficacy. Quality control is maintained through controlled sourcing of raw ingredients, manufacturing, packaging and labeling, as well as testing throughout the manufacturing process. Our commitment to quality ensures that our products meet or exceed the highest standards in the industry and that customers can trust the products and reinforces the value of our brand. We seek to differentiate ourselves in the marketplace by focusing on proprietary science-backed formulations that consumers can trust. Our ability to develop innovative solutions tailored to specific regulatory and consumer requirements in diverse global markets, while consolidating formulas and ensuring efficiencies of manufacturing scale, is a key factor in our international growth strategy. Our investment in R&D creates significant barriers to entry for competitors, as we leverage the diverse expertise of our team to address consumer needs while capitalizing on new opportunities in the nutritional supplement space. By combining strong scientific foundations with operational excellence, we enhance our ability to drive growth and deliver value to both our customers and shareholders. The R&D team is also involved in protecting our proprietary position with exclusive ingredients, proprietary formulations, product-specific scientific validation, and in some cases, patent protection. Research continues to support our proprietary InCelligence technology, advances in women’s health, immune system support, stress adaptation, healthy aging, and brain health. In 2024, we expanded our team of scientists focused specifically on research and reorganized our regulatory affairs and quality teams to further promote efficiency and quality. We also added Kathryn Armstrong, PhD, to our executive team to oversee all R&D efforts. In fiscal years 2024, 2023, and 2022, we expended $11.6 million, $11.4 million, and $11.6 million, respectively, on product R&D activities. We expect to continue investing in R&D to advance our expertise and leadership in cellular nutrition, as well as overall health and wellness. In 2025, we plan to continue our increased investments into early-stage research and scientific innovation as we believe these investments continue to provide a sustainable competitive advantage. Manufacturing and Quality Assurance We conduct manufacturing, production, and quality control operations for approximately 69% of our products in- house. We have established and maintain a manufacturing and quality control facility at our corporate headquarters in Salt Lake City, Utah. In 2019, we added a 54,000 square foot manufacturing facility located adjacent to our corporate headquarters, which expanded our manufacturing capabilities to allow us to manufacture our food products in-house. This adjacent facility started to produce product during the fourth quarter of 2020. BabyCare manufactures and produces the majority of its products in-house and maintains manufacturing and quality control facilities in Beijing, China and Tianjin, China. 8

Manufacturing Our production process uses automatic and semi-automatic equipment and includes the following activities by type: Tablet Manufacturing Foods Manufacturing Personal Care and Skincare Manufacturing Auditing and qualifying suppliers of raw materials x x x Acquiring raw materials x x x Analyzing raw material quality x x x Weighing or otherwise measuring raw materials x x x Mixing raw materials into batches x x x Forming mixtures into tablets x Converting batches into bars and/or finished powders x Coating and sorting the tablets x Analyzing tablet quality x Analyzing bars and/or finished powder quality x Analyzing liquid batch quality x Packaging finished products x x x Analyzing finished product quality x x x We conduct sample testing of raw materials, in-process materials, and finished products for purity, potency, and composition to determine whether our products conform to our internal specifications, and we maintain complete documentation for each of these tests. We employ a qualified staff of professionals to develop, implement, and maintain a quality system designed to assure that our products are manufactured to our internal and applicable regulatory agency specifications. Our Salt Lake City, Utah, manufacturing facilities are registered, as required, with the FDA, Health Canada Natural Health Products Directorate, the Australian Therapeutic Goods Administration (“TGA”), and other governmental agencies. These and other various organizations and government agencies regularly audit this facility to assess, among other things, compliance with current Good Manufacturing Practices (“GMPs”) and with labeling claims. Additionally, our Salt Lake City, Utah manufacturing facilities are certified, through inspection and audits, with the Islamic Foods and Nutrition Counsel of America in compliance with Halal, The Organized Kashrus Laboratories in compliance with Kosher, NSF International in compliance with product testing and GMPs, and the TGA in compliance with the current Therapeutic Goods Act in Australia. The manufacture of nutritional or dietary supplements and related products in the United States requires compliance with dietary supplement GMPs, which are based on the food-model GMPs and pharmaceutical GMPs, with additional requirements that are specific to dietary supplements. We are audited by the FDA, specifically for dietary supplements, and have historically been found to be in compliance with GMPs for dietary supplements. Although the FDA has not promulgated GMPs for personal care items, it has issued guidelines for manufacturing personal care products. We voluntarily maintain compliance with the guidance established by the FDA and the Personal Care Products Council. Our Beijing, China manufacturing facility is registered with State Administration of Market Regulation (“SAMR”), which includes the China Food and Drug Administration. Our facility in Beijing is audited regularly by various organizations and government agencies to assess, among other things, compliance with applicable GMPs, and with labeling claims. Third-Party Suppliers and Manufacturers We contract with third-party suppliers and manufacturers for the production of certain of our products, which accounted for approximately 31% of our product sales in 2024. These third-party suppliers and manufacturers produce and, in most cases, package these products according to formulations that have been developed by or in conjunction with our in- house product development team. These products include most of our gelatin-capsulated supplements, Rev3 Energy® 9

Drink, Probiotics, certain powdered drink mixes and Hiya's products. In 2025, we plan to continue transitioning the production of our powdered drink mixes to our USANA North facility. Products manufactured by third-party suppliers at their locations must also pass through quality control and assurance procedures to ensure they are manufactured in conformance with our specifications. As noted above, with the expansion of our manufacturing facility in Salt Lake City, Utah, we are able to manufacture our foods product line. Additionally, we plan to increase the proportion of the personal care and skincare products that we manufacture. This will reduce our reliance on third-party suppliers and manufacturers and add to our operating strengths, which are described below in this Annual Report. Quality Control and Assurance We have in-house microbiology and analytical chemistry labs in which we conduct quality control processes. In our microbiology laboratory, scientists test for biological contamination of raw materials and finished goods. In our analytical chemistry laboratory, scientists test for chemical contamination and accurate levels of active ingredients in both raw materials and finished products. Scientists also identify and confirm all raw materials used in the manufacturing process through scientifically valid means. Both laboratories conduct stability tests on finished products to determine the shelf life of our products. Our Salt Lake City, Utah laboratory staff also performs chemical assays on vitamin and mineral constituents, using USP methods and other internally validated methods. In addition to our quality control and clinical laboratories, both our headquarters and China facilities also house a laboratory designated for R&D. Raw Materials Most of the raw ingredients used in the manufacture of our products are available from a number of suppliers. Our raw material suppliers must demonstrate stringent process and quality control before we use their products in our manufacturing process. When supplies of certain raw materials have tightened, we have been able to find alternative sources of raw materials, and believe we will be able to do so in the future, if the need arises. Distribution and Marketing General We distribute our products internationally primarily through direct selling, which entails person-to-person marketing and selling of products. Direct selling is based on the strength of personal relationships and recommendations that frequently come from friends, neighbors, relatives, and close acquaintances. We believe that direct selling is an effective way to distribute our products because it allows person-to-person product education, as well as higher levels of customer service, all of which are not as readily available through other distribution channels. The Hiya Acquisition in 2024 expands our business into the direct-to-consumer distribution channel and provides a new and diversified opportunity for sales and customer growth. Structure of Direct Selling Program Overview. Although our direct selling philosophy and strategy are generally consistent in our markets around the world, certain aspects of our business may differ from market to market as a result of different legal and regulatory regimes, operational requirements or other factors. These differences may include how individuals join USANA, the compensation they are paid, the products they sell, and other components of their relationship with USANA. For example, China has enacted and maintains unique business laws and regulations governing direct selling that differ materially from our other markets around the world. Consequently, we have adjusted our direct selling program in China to comply with these laws and regulations. To do this, we operate our business in China through BabyCare. BabyCare utilizes a business model in China that is consistent with the philosophy of our world-wide business model, but differs in structure from our other markets. These differences are explained below under “China Business.” Associates. Outside of China, a person who wishes to sell USANA products must join our independent sales force as an Associate. A person becomes a USANA Associate by completing an application under the sponsorship of an existing Associate. The new Associate then becomes part of the sponsoring Associate’s sales organization. New Associates must agree to adhere to the USANA policies and procedures. Under our policies and procedures, Associates may not, among other things: (i) use deceptive or unlawful practices to sell USANA products; (ii) make deceptive or unlawful claims or representations concerning our products or Compensation Plan; or (iii) sell competitive products to other USANA Associates or solicit USANA Associates to participate in other direct selling opportunities. Associates who violate our policies are subject to discipline, which may include the termination of their purchase and distribution rights. New 10

Associates are required to purchase a starter kit that includes a detailed manual describing our business and products, as well as our policies and procedures. We sell these kits at a nominal price averaging approximately $12 in each of our markets and these kits are fully refundable under our return policy, which is described elsewhere in this report. No other direct investment is required to become an Associate. An Associate may purchase products directly from us at wholesale prices for their personal use and for resale to customers. Our Associates are also entitled to build sales organizations by attracting, enrolling and selling product to new customers. Associates are not required to recruit or sponsor new Associates and we do not compensate Associates for sponsoring or recruiting Associates. The sponsoring of new Associates results in the creation of multiple levels within our direct selling structure. Sponsored Associates are referred to as part of the sales organization of the sponsoring Associate. New Associates in turn may sponsor new Associates and Preferred Customers, creating additional levels in their sales network, but also forming a part of the same sales organization as the original sponsoring Associate. As outlined below, Associates who are interested in earning income with USANA must successfully sell USANA products and establish a network of product consumers in order to qualify for commissions, including bonuses. Subject to payment of a minimal annual account renewal fee, Associates may continue to distribute or consume our products as long as they adhere to our policies and procedures. Associate Compensation. This section describes our Associate Compensation Plan generally, except for our China operations, which are discussed separately below under the caption “China Business.” Our Compensation Plan provides several opportunities for Associates to earn compensation, provided they are willing to work consistently at (i) sharing, marketing and selling USANA products to consumers and (ii) building, training, and retaining their sales organizations. The purpose behind each form of compensation under our Compensation Plan is to reward committed Associates for generating product sales either directly or indirectly through their sales organization and network of product consumers. Associates can earn compensation under the Compensation Plan in four ways: • Commissions. The primary way an Associate is compensated is through earning commissions. Associates earn commissions by generating sales volume points, which are based on product sales of their sales organization. We have assigned each of our products a sales volume point value comprised of a certain percentage of the product price in U.S. dollars. To be eligible to earn commissions, an Associate must sell a certain amount of product each month. Associates do not earn commissions for simply recruiting and enrolling others in their organization. Commissions are paid only on the sale of products. In most markets, we pay Associates their commissions on a weekly basis. • Bonuses. We offer Associates several bonus opportunities, including our leadership bonus, elite bonus, and lifetime matching bonus. These bonus opportunities are based on a pay-for-performance philosophy and, therefore, are paid out when the Associate achieves certain performance measures. • Retail Mark-Ups. As discussed previously, in markets where retail mark-ups are permitted, our Associates purchase products from us at the Preferred Price and may resell them to consumers at higher retail prices. This allows the Associate to retain the retail mark-up as another form of compensation. • Contests and Promotions. We regularly sponsor contests and promotions designed to incentivize Associates to generate sales, grow their active Customer base and ultimately increase the number of USANA product users. These promotions are also based on a pay-for-performance philosophy and, therefore, are only paid upon the achievement of certain objectives. With the exception of our China market (discussed below), we endeavor to integrate our Compensation Plan across markets where legally permissible, allowing Associates to receive commissions for global product sales. This sales organization structure is designed to allow Associates to build a global network by establishing or expanding their sales organization in the markets where we operate. We believe our Compensation Plan significantly enhances our ability to expand internationally, and we intend to continue to integrate new markets, where permitted, into our Compensation Plan. Preferred Customers and Retail Customers. We also sell products directly to Preferred Customers and retail customers who purchase the products only for their personal use. Preferred Customers enroll with USANA, generally through an introduction by an Associate, and purchase product directly from the Company. Retail customers, however, generally purchase directly from Associates. Neither Preferred Customers nor retail customers may resell or distribute our products, regardless of where they purchased them. To sell USANA products, a Preferred Customer or retail customer must become an Associate. 11

These various customer programs give us access to a customer market that would otherwise be missed, by targeting consumers who enjoy USANA products, but who prefer not to maintain a distribution relationship with us. Although our policies prohibit Preferred Customers and retail customers from engaging in retail sales of products, they may enroll as Associates at any time in the future, if they desire. Affiliate program. We offer an Affiliate Program where Affiliates receive unique links to share with others. Affiliates earn a commission on all orders placed through their links, with commission percentages ranging from 15-20% of the product sale amount based on the product category. China Business. As explained above, the Chinese government maintains direct selling laws and regulations that differ materially from our other markets around the world. Although these laws and regulations permit direct selling, they impose a number of financial and operational restrictions, including a prohibition of pyramid selling and multi-level compensation systems. The Chinese government has also implemented a number of administrative and regulatory measures around direct selling to control these prohibited activities. To reduce the risk that the Chinese government might view BabyCare’s business model as conflicting with these laws and regulations, BabyCare utilizes a business model that is different from the model we use elsewhere in the world. BabyCare’s business model has been developed specifically for the China market and is based on, among other things: (i) BabyCare’s communications with the Chinese government, (ii) BabyCare’s interpretation of China's direct selling laws and regulations, as well as its understanding of how the government interprets and enforces these laws and regulations, and (iii) BabyCare’s understanding of how other multinational direct selling companies operate in China. Consequently, individuals who join BabyCare in China are compensated under BabyCare’s compensation plan, which has been established for China. Notwithstanding the foregoing, BabyCare has not received approval from the Chinese government that its business model, compensation plan or operations comply with applicable laws and regulations, including those pertaining to direct selling. BabyCare sells products in China through a variety of methods, including: (a) online through its website; (b) at physical branch retail locations; (c) through direct sellers in provinces and municipalities where BabyCare has received a direct selling license granted by the local provincial government; and (d) through independent distributors who are considered independent business owners under Chinese law. Individuals who reside in China and who are interested in being part of our business in China may do so by enrolling with BabyCare. While the process for enrolling with BabyCare is similar to the process for joining our business in other markets, individuals must initially enroll with BabyCare as either a traditional Preferred Customer (as described previously in this report) or China Preferred Customer ("CPC"). CPCs are similar to traditional Preferred Customers, but CPCs may also refer other CPCs and Preferred Customers in China and receive product vouchers from us to redeem on future product purchases based on the volume of product purchased by customers they have referred. A Preferred Customer or CPC may become a direct seller or independent distributor (which we report collectively as Associates) in China by electing to do so and agreeing to adhere to BabyCare’s policies and procedures in China. Our direct sellers in China are permitted by our policies and the terms of our direct selling licenses to sell product away from fixed retail locations in the provinces and municipalities where BabyCare has been granted a local direct selling license. Direct sellers are compensated for their sales under BabyCare’s compensation plan and do not receive compensation for promotional, marketing, or sales services that independent distributors are eligible to receive (as described below). Independent distributors are independent business owners who sell BabyCare’s products in China and also provide promotional, marketing, and sales services for BabyCare in China. Under BabyCare’s compensation plan, independent distributors are compensated not only for their own product sales, but also for their productivity in providing promotional, marketing and sales services. BabyCare’s compensation to its independent distributors for these services is intended and designed to be business-to-business compensation under Chinese law. To calculate independent distributor compensation for these services, we (i) use our world-wide Compensation Plan to track sales volume, and other metrics for the group of Preferred Customers, CPCs, distributors and others in China to whom the independent distributor provides promotional, marketing and sales services on behalf of BabyCare; (ii) calculate the fee-based compensation for the various services performed by the distributor; and (iii) pay the corresponding service fee to the independent distributor in China on a monthly basis. The fee-based compensation we pay our China independent distributors is comparable to the compensation available to our Associates in other markets and competitive with other direct selling companies in China. BabyCare’s business model, compensation plan, and operations in China involve certain risks and uncertainties, as discussed further in Item 1A. Risk Factors. We endeavor to mitigate these risks and uncertainties through various measures, including by seeking to understand and obey laws and regulations, training our employees and sales force, engaging in dialogue with government officials to better understand their goals and explain our plans, and cooperating in inquiries and other matters of interest to regulators. However, these efforts do not completely eliminate the significant risks associated with BabyCare’s operations in China. 12

Associate Training and Motivation. Initial training of Associates about USANA, our products and Compensation Plan, and global direct selling in general, is provided primarily by an Associate’s sponsor and others in the Associate’s sales organization. We develop and provide training materials and sales tools to assist Associates in building their businesses, and we provide reprints from commercial publications that feature USANA that may be used as sales tools. We also sponsor and conduct regional, national, and international Associate events, as well as intensive leadership training seminars. Attendance at these sessions is voluntary, and we undertake no generalized effort to provide individualized training to Associates, although experience shows that the most effective and successful Associates tend to be those who participate in such training activities. Although we provide leadership training and sales tools, we ultimately rely on our Associates to sell our products, attract new customers to purchase our products, and to educate and train new Associates regarding our products and Compensation Plan. Structure of Hiya Direct-to-Consumer Selling Program Hiya operates through a subscription-based direct-to-consumer business model. A customer's initial order from Hiya comes with a sustainable, refillable glass bottle that kids can personalize and additional orders come with educational material and games. Hiya also utilizes social media to promote sales across various platforms through brand-focused content and influencer partnerships. Hiya's diversified marketing also utilizes internet and social media keyword searches, influencers and paid advertisements, podcasts, advertorial publishing and direct mail campaigns. Operating Strengths Our vision is to improve the overall health and nutrition of individuals and families around the world. We do this through developing and manufacturing high-quality, science-based nutritional, and personal care and skincare products that promote long-term health, and providing a global direct selling opportunity for our Associates who desire to distribute our products and earn supplemental income. Our strategy is to capitalize on our operating strengths, which include (i) a strong R&D program; (ii) significant in-house manufacturing capability; (iii) high quality science-based products; (iv) a rewarding Associate Compensation Plan; (v) a scalable business model; and (vi) an experienced management team. Emphasis on Research and Development. We have a technical team of experienced scientists, including several holding doctoral degrees, quality engineers, and regulatory specialists who contribute to our R&D activities. In our R&D laboratories, our scientists and researchers: • Investigate activities of natural extracts and formulated products in laboratory and clinical settings; • Identify and research combinations of nutrients that may be candidates for new products; • Study the metabolic activities of existing and newly identified nutritional ingredients; • Enhance existing USANA brand products, as new discoveries in nutrition, personal care and skincare are made; • Formulate products to meet diverse regulatory requirements across all of our markets; and • Investigate processes for improving the production of our formulated products. Our in-house research team also conducts double-blind, placebo-controlled, clinical studies, which are intended to further evaluate the efficacy of our products. In addition, we collaborate with outside research organizations to further support various aspects of our R&D efforts. Our in-house research team has funded clinical research programs and works closely with scientists at a number of universities and research institutes, including those listed under the caption “Research and Development” above, to maintain our leadership in clinical research in nutrition, oxidative stress, glycemic stress, chronic inflammation and health implications of the microbiome. It is through our internal R&D efforts, as well as our relationships with outside research organizations and health care providers, that we can provide what we believe to be among the highest quality health products in the industry. In-house Manufacturing. We manufacture products that account for approximately 69% of our product sales. We believe that our ability to manufacture our own products in-house is a significant competitive advantage for the following reasons: • We can better control the quality of raw materials and finished products; 13

• We can more reliably monitor the manufacturing process to better guarantee potency and bioavailability and to reduce the risk of product contamination; • We can better control production schedules to increase the likelihood of maintaining an uninterrupted supply of products for our customers; • We are able to produce most of our own prototypes in the research phase of product development; and • We are better able to manage the underlying costs associated with manufacturing our products. Science-based Quality Products. As a result of our emphasis on R&D and our in-house manufacturing capabilities, we have developed a line of high quality products that we believe provide health benefits to our customers. Our products have been developed based on a combination of published research, in-house laboratory and third-party clinical studies, and sponsored research. Rewarding Associate Compensation Plan and Support. We are committed to increasing our product sales by providing a competitive compensation plan that attracts and retains Associates who constitute our sales force. We motivate our Associates by paying incentives on a weekly basis, in most markets. Where permissible, our Compensation Plan is implemented as a global-seamless plan, meaning that Associates can be compensated each week for their business success in any market in which they have product consumers and/or a sales organization where we conduct business. Our China operations maintain their own compensation plan, which is structured differently than our plan in other markets. In China, we pay Associates on a monthly basis. We plan to make certain modifications to our Associate compensation plan to enhance the earning opportunity for Associates and to prioritize sales and customer growth under the plan. To support our Associates, we sponsor virtual and in-person meetings and events throughout the year, where we offer information about our products and our global direct selling system. These meetings are designed to assist Associates in business development and to provide a forum for interaction with some of our Associate leaders and with members of our management team. Our strategy in 2025, and going forward, is to offer in-person meetings and events with our Associates to the extent health and safety practices make it possible. Our plan is to continue to leverage a virtual meeting element as a component of our in-person meetings. We also provide low-cost sales tools and resources, which we believe are an integral part of building and maintaining a successful home-based business for our Associates. In addition to company-sponsored meetings, sales tools and resources, we maintain a website exclusively for our Associates, where they can access the latest USANA news, obtain training materials, manage their personal information, enroll new customers, shop for products, and register for company-sponsored events. Additionally, through this website, Associates can access other online services to which they may subscribe. For example, we offer an online business management service, which includes a tool that helps Associates track and manage their business activity, a personal webpage to which prospects or retail customers can be directed, and e-cards for advertising. We also believe that recognition is an important factor in supporting and retaining our Associates. We understand that being a successful USANA Associate requires hard work and dedication, and we celebrate key achievements and rank advancements of our Associates. We believe that our recognition programs greatly contribute to our ability to retain our Associates. Direct Selling Business Model. We believe that our direct selling business model provides, among others, the following advantages: • No requirement for a company-employed sales force to sell our products, with a relatively low incremental cost to add a new active Customer; • Commissions paid to our Associates are tied to sales performance; • Accounts receivable are minimal because payment is required at the time a customer purchases product; • A stream of recurring revenue generated from our monthly product subscription program known as “Auto Order,” which we utilize in all of our markets (this program offers a 10% price discount and represented 63% of our product sales volume for the year ended December 28, 2024); and • The ability to expand into new international markets with moderate investment because we generally maintain only warehouse facilities, customer support, and minimal administrative facilities in those international markets. Larger markets, including China, however, require more significant local investment. 14

Hiya Direct-to-Consumer Business Model. We believe that our Hiya direct-to-consumer business model provides, among others, the following advantages: • Subscriptions provide a steady, predictable income stream, making it easier to manage cash flow and plan for growth; • The ongoing nature of subscriptions fosters stronger relationships with customers making it easier for them to receive products regularly, which leads to higher retention rates and loyalty; • Focus on retaining existing subscribers which lowers expenses on acquiring new customers; • Subscription model provides rich data on customer preferences and behaviors, which enables personalized offerings, efficient marketing and data-driven innovation insights; and • Accounts receivable are minimal because payment is required at the time of online purchase Experienced Management Team. Our management team includes individuals with expertise in various scientific and managerial disciplines, including global direct selling, nutrition, product research and development, international development, marketing, sales, information technology, manufacturing, accounting and finance, legal, regulatory, and operations. This team is responsible for supporting growth, R&D, international expansion, strengthening our financial condition, and improving our internal controls. Competition Our industry is very competitive and the barriers to entry are not significant. We compete with manufacturers, distributors, and retailers of nutritional products in many channels, including global direct selling, direct-to-consumer, specialty retail stores, wholesale stores, e-commerce businesses such as Amazon, and the internet generally. We also compete with other public and privately owned global network marketers for distributor talent, including for example Amway, Herbalife, and Nu Skin. On both fronts, compared to USANA, some of our competitors are significantly larger, have a longer operating history, higher visibility and name recognition, and greater financial resources. We compete with these entities by emphasizing to our Associates, Preferred Customers, and potential customers the strengths of our business, as described in the "Operating Strengths" section above. Product Returns Product returns have not been a material factor in our business, totaling approximately 0.6%, 0.6%, and 0.7% of net sales in 2024, 2023, and 2022, respectively. Customer satisfaction has always been and will continue to be a hallmark of our business. We believe that we have always offered a generous product return policy. Our standard return policy allows customers to receive a 100% refund on the purchase price on all product orders that are unused and returned within the first 30 days following purchase. Additionally, we offer a 100% refund of the sales price on all product orders by Associates that are unused and resalable up to one year from the date of purchase. To avoid manipulation of our Compensation Plan, return of product when the purchase amount exceeds $100 and the product was not damaged at the time of receipt by the Associate may result in cancellation of an Associate’s distributorship. This standard policy differs slightly in a few of our international markets due to applicable regulations in those markets. It also differs from our Hiya direct-to-consumer segment for which returns are allowed only in specific situations. To be considered, a return must be unopened in its original packaging postmarked within 10 days of the original delivery date. Major Customers We sell product to independent Associates, Preferred Customers, and retail customers. No single Associate, Preferred Customer, or retail customer accounted for 10% or more of net sales in any of the last three fiscal years. Notwithstanding the foregoing, the nature of our business model results in a significant amount of sales to several different Associate leaders and their sales organizations. Although no single Associate accounted for 10% or more of our annual net sales, the loss of a key Associate leader or that Associate’s sales organization could adversely affect our net sales and our overall operating results. See “Item 1A. Risk Factors.” Associate Compliance Our reputation depends upon the quality of our products and the integrity of our Associates. We continually monitor and review our Associates’ compliance with our policies and procedures as well as the laws and regulations applicable to our business around the world. Part of this review entails an assessment of our Associates’ sales activities to 15

ensure that they are actually selling products to consumers. Our policies and procedures require Associates to present our products and the USANA opportunity ethically and honestly. Associates are not permitted to make claims about our products or Compensation Plan that are not consistent with our policies and procedures and applicable laws and regulations. The majority of our Associates use marketing and promotional materials provided by USANA. Associates are permitted to produce their own marketing and promotional materials. However, prior to doing so, Associates are required to complete an Advertising Certification to help educate them and prevent them from making unapproved product and business claims (with the exception of Mainland China where Associates are only allowed to use advertising material created by the Company). In the ordinary course of our business, we encounter Associates who fail to adhere to our policies and procedures. We systematically review reports of alleged Associate misbehavior. Infractions of the policies and procedures are reported to our Ethics and Education group, who determine what, if any, disciplinary action is warranted in each case. More serious infractions are also reported to our Ethics Committee, which includes USANA executives. If we determine that an Associate has violated any of our policies and procedures, we may take a number of disciplinary actions, including warnings, fines or probation. Among other measures, we may also withdraw or deny awards, suspend privileges, withhold commissions until specific conditions are satisfied, or take other appropriate actions in our discretion, including termination of the Associate’s purchase and distribution rights. Because we believe that Associate compliance is critical to the integrity of our business, we are aggressive in ensuring that our Associates comply with our policies and procedures. When an Associate fails to comply with our policies and procedures, we may terminate the Associate’s purchase and distribution rights. From time to time, we become involved in litigation with Associates whose purchase and distribution rights have been terminated. We consider such litigation to be routine and incidental to our business and we will continue to be aggressive in ensuring that our Associates comply with our policies and procedures. Information Technology We believe that the ability to efficiently manage sales, active Customer data, distribution, compensation, manufacturing, inventory, accounting and finance, and communication functions through the use of secure, sophisticated, and dependable information processing systems is critical to our success. We continually evaluate changes in the information technology environment in connection with our efforts to capitalize on new technologies, keep pace with regulatory standards, and secure our systems and data. Over the last several years, we have meaningfully invested in technology systems and infrastructure to create a better overall customer experience for our customers and we will continue to invest in this area going forward. Our information technology resources are maintained primarily by our in-house staff to optimally support our customer base and core business processes. Our IT staff manages an array of systems and processes that support our global operations 24 hours a day and 365 days a year. Below is a list of our most critical applications: • A web-based application and native mobile applications that provide online services to Associates, such as training sessions, presentations, various communication tools, online shopping, enrollment, a real-time reporting engine, product information, web hosting, email, and other tools to help Associates effectively manage their business and sales organizations; • A web-based order-entry system that handles order entry, customer information, compensation, Associate business structure, returns, invoices, and other transactional-based processes; and • A fully integrated world-wide Enterprise Resource Planning (“ERP”) system that handles accounting, human resources, inventory management, production processes, quality assurance, and reporting requirements in a multinational environment. Our web applications are supported by a clustered environment providing high availability. All systems vital to the functioning of our organization are fully backed up and stored off-site to mitigate the risk of significant interruption of our business in the event of a disaster at the locations of our primary servers. For information regarding technology-related risks, see the information in “Item 1A: Risk Factors.” 16

Regulatory Matters General. In every jurisdiction in which we operate, our business is subject to extensive governmental regulation. These regulations exist at various national and local levels and pertain to our products, direct selling, and other aspects of our business. In this section, we describe the material regulations that are applicable to our business. Product Regulation. Numerous governmental agencies regulate the formulation, manufacturing, holding, packaging, labeling, advertising, promoting, importing, distributing, shipping, and selling of health supplements, cosmetics, and foods. In the United States, these agencies include the Federal Trade Commission (“FTC”) under the FTC Act, as amended, the FDA, under the Food, Drug, and Cosmetic Act, as amended (“FDCA”) and related regulations, the Consumer Product Safety Commission, the U.S. Department of Agriculture, the Environmental Protection Agency, the United States Customs and Border Patrol, and the United States Postal Service. Our largest selling product group includes products that are regulated as dietary supplements under the FDCA. Dietary supplements are also regulated in the United States under the Dietary Supplement Health and Education Act of 1994, as amended (“DSHEA”), which we believe is generally favorable to the dietary supplement industry. Some of our powdered drink, food bar, and other nutrition products are regulated as foods under the Nutrition Labeling and Education Act of 1990, as amended (“NLEA”). The NLEA establishes requirements for ingredient and nutritional labeling including product labeling claims. The manufacture of nutritional or dietary supplements and related products in the United States requires compliance with dietary supplement GMPs, which are based on the food-model GMPs and pharmaceutical GMPs, with additional requirements that are specific to dietary supplements. We are audited annually by the FDA, specifically for dietary supplements, and have been found in compliance with GMPs for dietary supplements. The Dietary Supplement & Nonprescription Drug Consumer Protection Act requires manufacturers of dietary supplements and over-the-counter (“OTC”) products to notify the FDA when they receive reports of serious adverse events occurring within the United States. We have an internal adverse event reporting system that has been in place for several years, and we believe that we comply with this law. In general, our personal care and skincare products, which are regulated as cosmetic products by the FDA, are not subject to pre-market approval by that agency. Cosmetics, however, are subject to regulation by the FDA under the adulteration and misbranding provisions of the FDCA. Cosmetics also are subject to specific labeling regulations, including warning statements, if the safety of a cosmetic is not adequately substantiated or if the product may be hazardous, as well as ingredient statements and other packaging requirements under The Fair Packaging and Labeling Act. Cosmetics that meet the definition of a drug, such as sunscreens, are regulated as drugs. OTC drug products, including cosmetics, may be marketed if they conform to the requirements of the OTC monograph that is applicable to that drug. Drug products not conforming to monograph requirements require an approved New Drug Application (“NDA”) before marketing may begin. Under these provisions, if the agency were to find that a product or ingredient of one of our OTC drug products is not generally recognized as safe and effective or is not included in a final monograph that is applicable to one of our OTC drug products, we would be required to reformulate or cease marketing that product until it is the subject of an approved NDA or until the time, if ever, that the monograph is amended to include such product. Advertising of our products in the United States is subject to regulation by the FTC under the FTC Act. Claims by us or our Associates about our products that cannot be adequately substantiated may be considered unfair or deceptive acts or practices and may expose us to liability under the FTC Act. In recent years, the FTC has initiated numerous investigations of and actions against companies that sell dietary supplement, weight-management, and cosmetic products. We believe that we have adequate substantiation for all material advertising claims that we make for our products in the United States, and we believe that we have organized the documentation to support our advertising and promotional practices. However, no assurance can be given that the FTC would reach the same conclusion if it were to review or question our substantiation for our advertising claims in the United States. The FTC may enforce compliance with the law in a variety of ways both administratively and judicially, using compulsory process, cease and desist orders, and injunctions. FTC enforcement can result in orders requiring, among other things, limits on advertising, corrective advertising, consumer redress, divestiture of assets, rescission of contracts, and such other relief as the agency deems necessary to protect the public. During 2020, for example, the FTC sent warning letters to several nutrition companies and direct selling companies in connection with advertising claims that the companies and/or their distributor sales people were making about the respective company's product's ability to prevent or treat COVID-19. In 2023, the FTC sent letters to nearly 700 companies, including USANA, warning them that the FTC, pursuant to its Penalty Offense Authority, could seek penalties for a company's failure to adequately substantiate product claims. The letter did not accuse any recipient company, including USANA, of engaging in unlawful conduct. But if the FTC later alleges that we have not adequately substantiated our product claims, we could be at risk of penalties and other 17

potential liability. Failure to adhere to FTC warning letters or other orders can result in substantial financial or other penalties. Although, to our knowledge, we have not been the subject of any action by the FTC, no assurance can be given that the FTC will not question our advertising or other operations in the United States in the future. Any action in the future by the FTC could materially and adversely affect our ability to market our products successfully in the United States. The manufacturing, labeling, and advertising of our products are also regulated by various governmental agencies outside the United States in each country where they are distributed. In China, our nutritional products are typically classified as “health functional foods” and our personal care and skincare products are classified typically as “non-special use cosmetics.” The registration process for health functional foods in China is complex and can be unpredictable. It generally requires extensive analysis and approval by the SAMR. As a result, it can take several years to register a product as a health functional food in China. While all products currently sold by BabyCare in China have been registered with the SAMR, we continue to work through the registration process for other health functional food products, which we also hope to begin selling through BabyCare in the future. SAMR and other governmental agencies also enforce advertising and other regulations that restrict the ability of health product companies to advertise the benefits of their products in China. In Australia, the TGA regulates product registration, labeling, and manufacturing. In Japan, the Ministry of Health, Labor, and Welfare regulates these activities. Upon entering a new market, prior to commencing operations or marketing products, we may be required to obtain approvals, licenses, or certifications from that country’s Food Administration, Ministry of Health, or comparable agency. Approvals or licensing may be conditioned on reformulation of USANA products for the particular market or approval or licensing otherwise may be unavailable with respect to certain products or product ingredients in a given market. We cannot predict the nature of any future laws, regulations, interpretations, or applications, nor can we determine what effect additional governmental regulations or administrative orders, when and if promulgated, would have on our business. Future changes could include requirements for the reformulation of certain products to meet new standards, the recall or discontinuation of certain products that cannot be reformulated, additional record keeping, expanded documentation of the properties of certain products, expanded or different labeling, and additional scientific substantiation. Any or all of these requirements could have a material adverse effect on our business, financial condition, and operating results. Direct Selling Regulation. Various laws and regulations in all of our markets regulate direct selling. These laws and regulations exist at many levels of government in many different forms, including statutes, rules, regulations, judicial decisions, and administrative orders. Direct selling regulations are inherently fact-based and often do not include “bright line” rules. In most of our markets, these regulations are subject to discretionary interpretation by regulators and respective legal authorities. Consequently, the regulations, or a regulator’s interpretation and enforcement of the regulations, could change at any time. If that were to occur, we may be required to change our business model in the respective market in an effort to comply. In the United States, the FTC has jurisdiction to regulate direct selling companies under the FTC Act. The FTC’s interpretation of the applicable direct selling laws and regulations has evolved over the last several years as represented in various consent orders between the FTC and certain direct selling companies, guidance issued by the FTC to the direct selling industry, and informal communications from the FTC to the industry. The FTC, through these consent orders, guidance, and communications, has addressed a variety of consumer protection issues, including misleading earnings representations by a company or its independent distributors, as well as the fairness and legal compliance of a company’s business model and distributor compensation plan. For example, in 2020, the FTC sent warning letters to several direct selling companies in connection with income claims allegedly made by the companies and/or their distributor sales forces in the context of the respective company's business opportunity͏ during the COVID-19 pandemic. The consent orders, guidance and communication from the FTC have also created a degree of ambiguity and uncertainty regarding how the FTC and other regulators will interpret the laws, regulations, and judicial precedent applicable to direct selling in the United States. In 2021, the FTC sent letters to over 1,100 companies, including USANA, warning them that the FTC could, pursuant to its Penalty Offense Authority, seek penalties for conduct determined to be unfair, deceptive, or otherwise unlawful in certain prior FTC actions. The letter did not accuse any recipient company, including USANA, of engaging in unlawful conduct. But if the FTC later alleges that we have engaged in acts or practices found to be unfair, deceptive, or unlawful in the actions referenced in the letters, we could be at risk of penalties and other potential liability. In 2025, the FTC issued a Notice of Proposed Rulemaking ("NPR") and an Advanced Notice of Proposed Rulemaking ("ANPR") regarding potential rules for earnings claims for direct selling companies. The NPR would, among 18

other things, prohibit direct selling companies from making deceptive earnings claims, and require them to maintain written substantiation to support any earnings claims and make that substantiation available to consumers upon request. Additionally, the FTC is considering, under the ANPR, additional restrictions on earnings claims and recruiting by direct selling companies that, if adopted, could harm our business. For more information about these risks and the other risks with the regulation of our overall business, direct selling business model, and compensation plan in this Annual Report, please see “Item 1A. “Risk Factors.” As noted above, the Chinese government has adopted direct selling laws and regulations that contain a number of financial and operational restrictions on direct selling companies, as well as prohibitions on pyramid selling and multi-level compensation. These regulations are subject to discretionary interpretation and enforcement by various municipal, provincial, and state officials in China. Departments within the Chinese government that regulate direct selling include the Ministry of Commerce (“MOFCOM”), the Ministry of Public Security (“MPS”), and their regional and local counterparts. BabyCare’s business model has been developed specifically for China based on, among other things: (i) BabyCare’s communications with the Chinese government, (ii) BabyCare’s interpretation of the direct selling laws and regulations, as well as its understanding of how the government interprets and enforces the regulations, and (iii) BabyCare’s understanding of how other multinational direct selling companies operate in China. Notwithstanding the foregoing, the direct selling industry in China, as well as the regulatory environment for the industry, continues to evolve and receive significant attention and scrutiny from the Chinese government and the Chinese media. In 2019, following unfavorable media coverage of certain health product companies and direct selling companies, several departments of the Chinese government, including SAMR, MPS, and MOFCOM, initiated a review of health product and direct selling companies. This review required direct selling companies in China such as BabyCare to conduct a self-assessment of the regulatory compliance of their business (including product regulatory compliance and direct selling regulatory compliance) and to provide information to the Chinese government regarding that assessment. The review also entailed a review of direct sellers' regulatory compliance by various departments of the Chinese government. During this review, the Chinese government, among other things, instructed direct selling companies not to hold large distributor meetings, and suspended its application review process for direct selling licenses and authorizations. The Chinese government has yet to re-open the application review process for direct selling licenses and authorizations or indicate if or when it plans to do so. The Chinese government's scrutiny of the direct selling industry has been higher following the 2019 review. The Chinese government has taken action historically against direct selling companies that it believes have violated the government’s direct selling regulations and anti-pyramiding laws. The government’s action in this regard has entailed investigating direct selling companies and their distributors, imposing significant fines and, in some cases, shutting down companies it believed to be in violation. Historically, there have been instances when inquiries or complaints about BabyCare’s business resulted in warnings from the Chinese government, as well as the payment of fines by BabyCare or its distributors. BabyCare has obtained direct selling licenses in certain provinces and municipalities in China, but must obtain others from additional provinces and municipalities if it is to continue to expand its direct selling business model in China. As of the date of this Annual Report, BabyCare has been granted licenses to engage in direct selling in the provinces and municipalities of Beijing, Jiangsu, Shaanxi, and Tianjin. Direct selling companies, and the industry in general, continue to experience significant media and public scrutiny. Several companies similar to USANA recently have been scrutinized and penalized in several markets where we operate, including the United States, Canada, China, Japan, and South Korea. This scrutiny, along with the uncertainty of the laws and regulations pertaining to direct selling in many countries, can affect how a regulator or member of the public, including investors, perceives us. For instance, there has been significant media and short-seller attention given to the viability and legality of direct selling in the United States and China over the past few years. This attention has led to intense public scrutiny of our industry, as well as volatility in our stock price and the stock prices of other direct selling companies who operate in the same markets. We cannot predict the impact that this scrutiny may have on our business or industry in the future. We detail more of the various risks associated with the regulation of our overall business, direct selling business model, and Compensation Plan in this Annual Report in “Item 1A. “Risk Factors.” Transfer Pricing Regulation. In the United States and many other countries, we are subject to transfer pricing and other tax regulations designed to ensure that appropriate levels of income are reported by our United States or international entities and taxed accordingly. We have adopted transfer prices, which are supported by formal transfer pricing studies, for 19

the sale of products to our subsidiaries in accordance with applicable transfer pricing laws. In addition, we have entered into agreements with our subsidiaries for services and other contractual obligations, such as the payment of Associate incentives that are also supported by the same formal transfer pricing studies. We have experienced instances in the past where international taxing authorities have successfully challenged our transfer pricing calculations and agreements and assessed us additional tax. Going forward, if the U.S. Internal Revenue Service (“IRS”) or the taxing authorities of any other jurisdiction successfully challenge these agreements or require changes in our standard transfer pricing practices for products, we could become subject to higher taxes and our earnings could be adversely affected. The tax treaties between the United States and most countries provide competent authority for relief to avoid any double taxation. We believe that we operate in compliance with all applicable transfer pricing regulations. There can be no assurance, however, that we will continue to be found to be operating in compliance with transfer pricing regulations or that those laws will not be modified, which may require that we change our operating procedures. In addition, the organization for Economic Co-operation and Development, or OECD, has released guidance covering various international tax standards as part of its “base erosion and profit shifting,” or BEPS, initiative. On December 20, 2021, the OECD published model rules around two groups of proposals for global tax reform labeled “Pillar One” and "Pillar Two”. Pillar One provides a framework for taxing rights more closely aligned with the location of consumer engagement. Pillar Two establishes a global minimum tax rate of 15% and would apply on income that is taxed less than 15% in any taxing jurisdiction. In December 2022, the EU member states agreed to implement the OECD framework in their domestic tax laws with a target effective date for the 15% global minimum tax rate in 2024. The OECD has issued additional guidance in 2023, 2024 and more guidance is expected in 2025. We continue to evaluate the potential impact of the OECD model rules and guidance on the Company. There can be no assurance that future legislative, regulatory, or judicial developments will not result in an increase in the amount of taxes payable by the Company. Intellectual Property Trademarks. We have developed and use registered trademarks in our business, particularly relating to our product names. We own 30 trademarks that are registered with the U.S. Patent and Trademark Office. Additionally, as disclosed elsewhere in this report, we completed the Hiya Acquisition on December 23, 2024, and Hiya owns five trademarks registered with the U.S. Patent and Trademark Office. Federal registration of a trademark enables the registered owner of the mark to bar the unauthorized use of the registered mark by a third party in connection with a similar product in similar channels of trade anywhere in the United States, regardless of whether the registered owner has ever used the trademark in the area where the unauthorized use occurs. We have filed applications and own trademark registrations, and we intend to register additional trademarks in countries outside the United States where USANA products are or may be sold in the future. Protection of registered trademarks in some jurisdictions may not be as extensive as the protection in the United States. We also claim ownership and protection of certain product names, unregistered trademarks, and service marks under common law. Common law trademark rights do not provide the same level of protection that is afforded by the registration of a trademark. In addition, common law trademark rights are limited to the geographic area in which the trademark is actually used. We believe these trademarks, whether registered or claimed under common law, constitute valuable assets, adding to recognition of USANA and the effective marketing of USANA products. Trademark registration once obtained is essentially perpetual, subject to the payment of a renewal fee and continued usage of the trademark. We therefore believe that these proprietary rights have been and will continue to be important in enabling us to compete. Patent. We own U.S. Patent 10,632,101 for our InCelligence complex formula. This patent was issued in 2020. Trade Secrets. We own certain intellectual property, including trade secrets that we seek to protect, in part, through operational protections and confidentiality agreements with employees, consultants, vendors and other parties. Even where these agreements exist, there can be no assurance that these agreements will not be breached, that we would have adequate remedies for any breach, or that our trade secrets will not otherwise become known to or independently developed by competitors. Our proprietary product formulations are generally considered trade secrets, but are not otherwise protected under intellectual property laws. We intend to protect our legal rights concerning intellectual property by taking all appropriate legal action. Consequently, we may become involved from time to time in litigation to determine the enforceability, scope, and validity of any of the foregoing proprietary rights. Any intellectual property litigation could result in substantial cost and divert the efforts of management and technical personnel. 20

Seasonality We experience variations in the activity of our direct selling customers in many of our markets in the first and fourth quarters around major cultural events such as Lunar New Year and Christmas. Backlog Our products are typically shipped within 72 hours after receipt of an order. As of March 7, 2025, we had no significant backlog of orders. Working Capital Practices Due to our dual role as manufacturer and distributor, we require substantial inventories, as such, we strive to maintain sufficient amounts of inventory in order to provide a high level of service to our customers. At times we may strategically choose to carry a greater amount of inventory for various reasons, such as promotional activity, product launches, and uncertainty in supply and distribution channels. We also watch seasonal commodity markets and may buy ahead of normal demand to hedge against cost increases and supply risks. Environment Laws We are not aware of any instance in which we have contravened federal, state, or local laws relating to protection of the environment or in which we otherwise may be subject to liability for environmental conditions that could materially affect operations. Our Values and Culture Our business is driven by our four Core Values: • Excellence: We rely on scientific research to provide innovative, healthy living solutions, and we empower all individuals to continually improve each day. • Community: We support, care for, and encourage one another, and the world, to live happier, healthier lives. • Integrity͏: We demonstrate honesty, responsibility, and accountability through our individual actions and corporate decision-making. • Health: We cultivate a holistic view of wellness that supports a healthy body and a strong mind. Corporate Sustainability The Sustainability Committee of the Board of Directors oversees and advises on all matters related to corporate sustainability. The Sustainability Committee is composed of directors Peggie Pelosi, Chair; John Fleming; Frederic Winssinger; Tim Wood; and J. Scott Nixon. The corporate sustainability effort focuses on issues that address enterprise risk and the overall strength and resilience of our business by addressing potential impacts on customer acquisition and retention, employee engagement, continuity of operations, and support of the communities and environment in which we operate. In the United States and abroad there are an increasing number of sustainability-related rules and regulations that have been adopted or proposed. Such regulations may subject us to new disclosure requirements, which could result in risks to our reputation or consumer demand for our products if we do not meet increasingly demanding stakeholder expectations and standards. We will continue to incorporate and advance sustainability-related best practices across all of our markets as part of our commitment to improving the health and wellness of individuals, families and communities around the world. Our sustainability strategy centers on three main pillars - products, people, and planet - that encompass where we are focusing our sustainability efforts now and in the future. To achieve our objectives, we plan to continue fortifying each 21

pillar, to deliver meaningful progress while evolving our efforts to ensure our business becomes more sustainable day by day. Strategic Pillars Tier One Topics Tier Two Topics Products • Product quality and safety • Responsible sourcing • Health and nutrition • Affordable and accessible products People • Talent management and development • Employee health, safety, and well- being • Inclusion and belonging • Human rights Planet • Sustainable packaging • Waste management • Greenhouse gas management • Biodiversity and environmental conservation • Energy management • Water management We encourage you to review our most recent Sustainability Report available on our investor relations website https://ir.usana.com/ for more detailed information regarding our human capital programs and initiatives. Nothing on our website, including our Sustainability Report or sections thereof, is deemed incorporated by reference into this Report. Human Capital We believe that "creating the healthiest family on earth" starts with our employees. Key to our ambition is giving our employees the skills and development they need to build a meaningful career and tools to support their total health and wellness and enhancing our diverse and inclusive workplace culture to help employees thrive. We also believe that the manner in which we address issues related to workforce demographics, inclusion and belonging, community involvement, talent management, compensation and benefits, and employee health and safety directly correlates to our success as a business. As of December 28, 2024, we had approximately 1,700 employees working in 22 countries worldwide, as measured by full-time equivalency. The majority of our employee population resides in the United States (45%) and China (29%). Approximately 57% of our world-wide employee population is female. We are actively working through initiatives such as our Women in Leadership Program, along with formal and informal mentorship programs, to continue promoting and hiring talented and capable women into management roles. We have also increased the number of women in leadership roles over the past several years with 51% of total leadership positions currently being held by females. This is important to enhance our understanding of the needs and expectations of USANA's largest group of customers and associates, females. Our employees are not currently represented by a collective bargaining agreement, and we have not experienced work stoppages as a result of labor disputes. We believe that we have a good relationship with our employees. We are committed to fostering a diverse, inclusive and equitable workplace. Our inclusion and belonging program is designed to promote representation and engagement at all levels of the organization. Through our mentorship program and Women in Leadership initiative, we are working to increase representation of underrepresented groups in leadership positions. Our inclusion and belonging council focuses on education and awareness, access to developmental programs, and community engagement. One of the key elements of our inclusion and belonging program is our commitment to volunteerism and charitable action. In 2024, we spent more than 2,600 hours volunteering, working with local organizations to help promote inclusion and belonging in the communities where we operate. Additionally, we continued our support of programs that foster career development and help to ensure that all employees have the opportunity to reach their full potential. In addition to these internal initiatives, we also partner with other organizations to help achieve our inclusion and belonging goals. By working together with other companies, community groups, and non-profits, we are able to amplify our impact and create a more inclusive and equitable society for all. Our inclusion and belonging program is a key component of our company culture and enables us to create a more vibrant and innovative workplace that benefits all of our employees, customers, and stakeholders. We will continue to invest in this program, and strive to make our company an inclusive, equitable and welcoming place for all. 22

We understand the value of developing employees at every level. Our leaders actively participate in leadership development programs that include mentorship and coaching, online learning, and regular company and industry specific training programs. Additionally, our global employee population is engaged in online learning platforms and, more than 445 participants have completed our mentorship and coaching program. All employees are encouraged to attend training specific to their role, as well as, utilize our tuition reimbursement program, which has provided additional monetary support to employees at all levels as they pursue bachelor and advanced college degrees. The health and safety of employees is also a key element in providing return to all stakeholders. In addition to following mandatory government requirements for health and safety, we have established a wellness program that includes free nutritional products to employees. Employees in our corporate headquarters have access to an on-site gym, exercise classes, free access to massages, and chiropractic care. A health clinic located on the campus of our corporate headquarters provides medical and mental health care, and is actively engaged in the health of about 54% of our eligible employees. We recognize that a strong commitment to community is essential to all stakeholders. We utilize the USANA Foundation, which operates independently of the Company, to provide philanthropic nutrition to underserved children and families worldwide. In 2024, the USANA Foundation: • Provided over 30 million meals; • Provided aid and grants to partner charities around the world; • Distributed backpacks of food for at risk children in local schools to take home on the weekend and during long holiday breaks; and • Gifted bottles of children's vitamins to some of the most malnourished children around the world. A discussion of the risks relating to our ability to attract and retain active Associates and Preferred Customers, and the loss of key management, is included in Item 1A. Risk Factors.

These risk factors are not necessarily in the order of importance or probability of occurrence: You should consider the following risk factors, in addition to the information presented elsewhere in this Annual Report, particularly under the heading “Cautionary Note Regarding Forward-Looking Statements,” on page 1, and the disclosures contained in Part I, “Item 1. Business,” and Part II, “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this report, as well as in the other filings we make from time to time with the SEC, in evaluating us, our business and an investment in our securities. 24

Below is a summary of the principal factors that make an investment in the common stock of the Company risky or speculative. This summary does not address all of the risks we face. Unless otherwise indicated or otherwise required by the context, the terms “we,” “our,” “it,” “its,” “Company,” and “USANA” refer to USANA Health Sciences, Inc. and its wholly owned subsidiaries. Risks Associated with Direct Selling • Direct selling is subject to intense government scrutiny, and regulation and changes in the law, or the interpretation and enforcement of the law, might adversely affect our business. • The violation of marketing or advertising laws by Associates in connection with the sale of our products or the improper promotion of our Compensation Plan could adversely affect our business. • We may have or could incur obligations relating to the activities of our Associates. • Our Associate Compensation Plan, or changes we make to it, may be viewed negatively by some Associates, could fail to achieve our desired objectives, and could have a negative impact on our business. • Changes we are required to make to our Associate Compensation Plan in certain markets, including limits on the amount of Associate compensation we can pay, may hurt our ability to attract and retain Associates, result in regulatory risk and affect our operating results. Risks Related to Our China Business • Our Greater China region accounts for a significant part of our business and expected growth. A decline in sales or customers in this region would harm our business, financial condition and results of operations. • Our operations in China are subject to significant government regulation, as well as a variety of legal, political, and economic risks. If the Chinese government modifies its direct selling laws and regulations, or interprets and enforces these laws and regulations in a manner that is adverse to our business in China, our consolidated business and results of operations may be materially harmed. • Although BabyCare Holdings, Ltd. (“BabyCare”) utilizes a business model that has been developed specifically for China’s laws and regulations, the Chinese government has not approved BabyCare’s model, compensation plan, and operations. • BabyCare’s operations in China, and direct selling companies in general, are subject to significant government oversight, scrutiny and monitoring. • BabyCare must apply for and receive government approval to expand its business in China and the failure to obtain such approvals could negatively impact its ability to expand and grow its business. Risk Associated with Our International Operations • Risks associated with operating in international markets could restrict our ability to expand globally and harm our business and prospects. • Trade policies, disputes, tariffs or other international disputes could harm our business and operating results. • Because some of our customers and suppliers are based in China, our business, financial condition, and results of operations could be adversely affected by the political and economic tensions between the United States and China. • We are subject to various governmental export control and trade sanctions laws and regulations that could impair our ability to compete in international markets or subject us to liability if we violate these controls. • Fluctuation in the value of currency exchange rates with the U.S. dollar affects our operations and our net sales and earnings. • Inflationary pressures and persistently high prices and uncertain availability of commodities, raw materials or other inputs used by us and our suppliers, or instability in logistics and related costs, could negatively impact our profitability. Risks Related to Our Products, Manufacturing and Operations • Our products and manufacturing activities are subject to extensive government regulation, which could limit or prevent the sale of our products in some markets. • Our in-house manufacturing activity is subject to certain risks. • Our reliance on third parties to manufacture and supply certain of our products may harm our business, financial condition and operating results. • The inability to obtain adequate supplies of raw materials for products at favorable prices, or at all, could have a material adverse effect on our business, financial condition, or operating results. • Delays and disruptions to transporting and distributing our products may adversely affect our results. • We may incur liability with respect to our products. • Nutritional supplement products may be supported by only limited availability of conclusive clinical studies. 25

Legal, Regulatory, Compliance and Tax Risks • Legal action by former Associates or third parties against us could harm our business. • We may incur liability under our “Athlete Guarantee” program. • Failure to comply with anti-corruption laws could adversely affect our business. • We could be subject to adverse changes in tax laws, regulations and interpretations or challenges to our tax positions. • If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud. • Environmental, Social, and Governance ("ESG") issues may have an adverse effect on our reputation, business, financial condition or results of operations. Risk Associated with Information Technology, Data Security and Data Privacy • A failure or interruption of our information technology systems would harm our business. • We rely on information technology to support our operations and reporting environments. A data breach involving that technology or the data stored in it, could disrupt our ability to operate our businesses effectively, adversely affect our reported financial results and our reputation, and expose us to significant potential liability, government investigations, fines or litigation. • We are subject to data privacy and security laws and regulations, and our actual or perceived failure to comply with them could adversely affect our business and operating results. Human Capital Risks Associated with our Business • If we are unable to attract and retain active Associates and Preferred Customers, our business may be harmed. • The loss of key management personnel could adversely affect our business. Risks Associated with Business Development Activities and Acquisitions • Growth through acquisitions is part of our strategy, and we may not successfully integrate, operate or realize the anticipated benefits of our acquisitions. • The Hiya Acquisition may not be accretive, and may be dilutive, to our earnings per share, which may negatively affect the market price of our common stock. • Although we expect that the Hiya acquisition will result in synergies and other benefits to us, we may not realize those benefits because of challenges inherently associated with integration, performance and the achievement of synergies. • The Hiya Acquisition and integration may result in additional costs and expenses. • The Hiya Acquisition may be viewed negatively by our Associates. General Economic, Publicity, Competitive, and Intellectual Property Risks Associated with our Business • Difficult economic conditions may adversely affect our business. • Our business is subject to the effects of adverse publicity and negative public perception. • Our business is subject to the risks associated with intense competition from larger, wealthier, and more established competitors. • Our business is subject to particular intellectual property risks. Risks Related to Public Health Crises • Pandemics, epidemics, disease outbreaks and other public health crises, such as the COVID-19 pandemic, have disrupted our business and operations, and future public health crises could materially adversely impact our business, financial condition, liquidity and results of operations. Risks Related to Our Common Stock • The beneficial ownership of a significant percentage of our common stock gives our founder and parties related to or affiliated with him effective control, and limits the influence of other shareholders on important policy and management issues. • Sales by our shareholders of a substantial number of shares of our common stock in the public market could adversely affect the market price of our common stock. • The market price of our common stock may be influenced by many factors, some of which are beyond our control. 26

Risk Associated with Direct Selling Direct selling is subject to intense government scrutiny, and regulation and changes in the law, or the interpretation and enforcement of the law, might adversely affect our business. Various laws and regulations in the United States and other countries regulate direct selling. These laws and regulations exist at many levels of government in many different forms, are inherently fact-based, and often do not include “bright line” rules. We are also subject to the risk that the laws and regulations, or a regulator’s interpretation and enforcement of the laws and regulations, could change. In the United States, the FTC is one of many regulators who regulate direct selling. The FTC has actively warned various direct selling companies and the industry as a whole about certain business practices associated with direct selling and entered into settlements with several direct selling companies that required those companies to modify their compensation plans and business models. Those settlements resulted from enforcement actions brought by the FTC involving a variety of alleged violations of consumer protection laws, including misleading product claims, misleading earnings representations and legal compliance of those companies’ business models and distributor compensation plans. For example, in 2016, the FTC entered into a settlement with another direct selling company following an enforcement action in which the FTC alleged that the company’s distributors were making misleading earnings representations and that the company was utilizing an illegal business model. Also in 2016, the FTC entered into a settlement with another direct selling company following an enforcement action in which the FTC alleged that the company’s distributors had made misleading income representations and that the company was utilizing an unfair and deceptive compensation plan. In 2019, the FTC entered into a settlement with a direct selling company following an FTC enforcement action, which included the alleged violations noted above. Pursuant to this settlement, the company is permanently prohibited from using a multilevel compensation plan in the United States. Following this settlement, the FTC initiated litigation with another direct selling company for similar alleged violations and pursued similar claims and remedies, including a prohibition of multilevel compensation in the United States. Although the court ruled in favor of the defendant company in this case, settlements such as those described in the other cases above may require a direct selling company to pay a significant fine, revise its U.S. business model and compensation plan to comply with various restrictions on how it can compensate distributors and change its marketing practices to avoid misleading product or income representations, among other things. Although a settlement between the FTC and a specific company does not generally have force of law or binding effect on other companies, FTC officials have indicated that the direct selling industry should look to these settlements, and the principles contained therein, for guidance. In 2020, the FTC sent warning letters to several direct selling companies regarding product and/or income claims that the companies and/or their distributors were making related to the COVID-19 pandemic. In 2021, the FTC sent letters to over 1,100 companies, including USANA, warning them that the FTC, pursuant to its Penalty Offense Authority, could seek penalties for conduct determined to be unfair, deceptive, or otherwise unlawful in certain prior FTC actions. In 2023, the FTC sent letters to nearly 700 companies, including USANA, warning them that the FTC, pursuant to its Penalty Offense Authority, could seek penalties for a company's failure to adequately substantiate its product claims. The 2021 and 2023 letters did not accuse any recipient company, including USANA, of engaging in unlawful conduct. But if the FTC later alleges that we have engaged in the actions referenced in the 2021 or 2023 letters, we could be at risk of penalties and other potential liability. In 2025, the FTC issued a Notice of Proposed Rulemaking ("NPR") and an Advanced Notice of Proposed Rulemaking ("ANPR") regarding potential rules for earnings claims for direct selling companies. The NPR would, among other things, prohibit direct selling companies from making misleading earnings claims, and require them to maintain written substantiation to support any earnings claims and make that substantiation available upon request. Under the ANPR, the FTC is considering additional restrictions on earnings claims and recruiting by direct selling companies that, if adopted, could have a material adverse effects on our business. Additionally, the FTC’s increased scrutiny of earnings claims, as reflected in the NPR and ANPR, could lead to new industry standards, other new rules, or more FTC actions regarding misleading claims, all of which could limit our ability to advertise and negatively impact our business. We regularly analyze our business model in response to settlements between the FTC and other direct selling companies, as well as guidance and other communications issued by the FTC, and from time to time we refine aspects of our business model where appropriate. While we maintain a robust Associate compliance program and strive to educate our Associates on compliant claims, if a regulator determines we are making misleading claims, this could lead to an FTC investigation, which could harm our business operations. Additionally, while we strive to ensure that our compensation plan is compliant with applicable laws and regulatory guidance in each of our markets, we cannot assure you that a 27

regulator, if it were to review our business, would agree with our assessment and would not require us to change one or more aspects of our operations. Any action against us in the future by the FTC or another regulator could materially and adversely affect our operations. We are also subject to various direct selling laws and regulations in our other markets, including China (as explained below). We cannot predict the nature of any future law, regulation, or guidance, nor can we predict what effect additional governmental regulations, judicial decisions, or administrative orders would have on our business. Failure by us, or our Associates, to comply with these laws, regulations, or guidance, could have a material adverse effect on our business in a particular market or in general. Finally, the continuation of regulatory challenges, investigations and litigation against other direct selling companies could harm our business and industry if the laws and regulations are interpreted in a way that results in additional restrictions on direct selling companies in general. The violation of marketing or advertising laws by Associates in connection with the sale of our products or the improper promotion of our Compensation Plan could adversely affect our business. All Associates contractually agree to adhere to our policies. Although these policies prohibit Associates from making false, misleading and other improper claims regarding products or income potential from the sale of the products, from time to time Associates, without our knowledge and in violation of our policies, create promotional materials or otherwise provide information that does not accurately describe USANA, our products or the Compensation Plan. They also may make statements regarding potential earnings, product claims, or other matters in violation of our policies or applicable laws and regulations concerning these matters. These violations may result in legal action against us in our various markets by regulatory agencies, state attorneys general, or private parties. Legal actions against us or our Associates or others who are associated with us could lead to increased regulatory scrutiny of our business, including our business model. While we take what we believe to be commercially reasonable steps to regularly train our Associates, and monitor their activities to promote compliance with our policies and guard against illegal or unethical conduct by Associates, there can be no assurance that our efforts will be sufficient to accomplish this objective. In the past, we have experienced adverse publicity both within and outside of our sales force for enforcing our Associate policies and procedures. This type of adverse publicity has made, and will continue to make, it difficult for us to attract and retain Associates and Preferred Customers and may have an adverse effect on our business, financial condition, and results of operations. We may have or could incur obligations relating to the activities of our Associates. Our Associates are subject to taxation, and, in some instances, legislation or governmental agencies may impose an obligation on us to collect taxes, such as sales taxes or value added taxes, and to maintain appropriate records of such transactions. In addition, we are subject to the risk in some jurisdictions of being responsible for social security and similar taxes as well as employee benefits with respect to our Associates. In particular, the laws regarding independent contractor status in certain jurisdictions, including the United States, continue to evolve and, in some cases, authorities have sought to apply these laws unfavorably against gig economy, platform and direct selling companies, including USANA. In 2020, we were named as a defendant in a private lawsuit in California by a plaintiff’s firm that is seeking to reclassify our California Associates from independent contractors to employees under California state law. Although we prevailed in this litigation and continue to believe we have legally and appropriately classified our Associates as independent contractors, it is possible that future lawsuits or potential future laws, could negatively impact the independent contractor status of our Associates or distributors in direct selling companies in general. In March 2024, a new Department of Labor (DOL) rule regarding the classification of workers as employees vs. independent contractors under the Fair Labor Standards Act went into effect but became subject to litigation. If the 2024 DOL final rule or other federal, state or local laws and regulations or the interpretation of such laws and regulations require us to treat our Associates as employees, or if our Associates are deemed by local regulatory authorities in one or more of the jurisdictions in which we operate to be our employees rather than independent contractors, under existing laws and interpretations, we may be deemed to be responsible for a variety of obligations that are imposed upon employers relating to their employees, including social security and related taxes in those jurisdictions, wages, employee benefits, plus any related assessments and penalties, which could harm our financial condition and operating results. Our Associate Compensation Plan, or changes we make to it, may be viewed negatively by some Associates, could fail to achieve our desired objectives, and could have a negative impact on our business. From time to time, we modify our Compensation Plan to (i) keep it competitive and attractive, (ii) cause or address a change in Associate behavior, (iii) conform to legal and regulatory requirements, or (iv) address other business needs. It is difficult to predict how any changes to the plan will be viewed by Associates and whether such changes will 28

achieve their desired results. For example, in 2023 we launched our Affiliate program in three markets and this program creates a new and different element of our Compensation Plan. In 2025, we are also making certain modifications to our Compensation Plan to enhance the earning opportunity for Associates and prioritize sales and customer growth. There can be no assurance that changes to our Associate Compensation Plan will allow us to successfully attract new Associates or retain existing Associates, nor can we assure that any changes we make to our Compensation Plan will achieve our desired results. We may also face legal challenges and disputes from our Associates in one or more markets regarding changes to the Compensation Plan. Additionally, the payment of Associate incentives under our Compensation Plan is our most significant expense. Modifying our Compensation Plan directly affects the incentives we pay as a percentage of net sales. There can be no assurance that changes to the Compensation Plan will be successful in achieving target levels of Associate incentives as a percentage of net sales. Furthermore, such changes may make it difficult to attract and retain qualified and motivated Associates. Changes we are required to make to our Associate Compensation Plan in certain markets, including limits on the amount of Associate compensation we can pay, may hurt our ability to attract and retain Associates, result in regulatory risk and affect our operating results. We have been required to modify our Associate Compensation Plan in certain markets to comply with the laws and regulations in these markets or the interpretation of the same by authorities in these markets. For example, we have been required to use a different compensation plan for our BabyCare operations in China (as noted elsewhere in this report) and have been required to modify our Compensation Plan in India, South Korea, Malaysia, and Indonesia to comply with applicable laws and regulations. We obtain regulatory approval of our Compensation Plan when required or, when not required, we may seek a legal opinion regarding compliance. We may also be prohibited from distributing products through direct selling or paying multilevel compensation in some countries. Several markets, including China, South Korea, and Indonesia also impose limits on the amount of compensation we can pay to our Associate sales force. If we fail to comply with the legal requirements for our Compensation Plan in our various markets, including the limits on compensation we are legally permitted to pay, we may incur fines or other sanctions, including the loss of applicable licenses to conduct our business. These required changes to our Compensation Plan, including compensation limits, may also be viewed as limiting the incentive for people to join our Associate sales force and may reduce the competitive advantage of our Associate Compensation Plan. Risks Related to Our China Business Our Greater China region accounts for a significant part of our business and expected growth. A decline in sales or customers in this region would harm our business, financial condition and results of operations. Our Greater China region consists of China, Hong Kong, and Taiwan and has been our largest region for sales over the last several years and China has been our largest market. Our international growth strategy has focused largely on growing our China business. For the last several years, officials in Greater China have responded to the COVID-19 pandemic and, more recently, overall economic conditions in China, all of which have created a challenging operating environment for our business in China and negatively impacted our sales and customer results. Prior to that, in 2019, our sales and active Customer counts in both the Greater China region and our China market declined, largely because of a challenging operating environment in China, following the China’s governments inquiry into and review of the health foods industry in China. If we are not successful in growing BabyCare’s sales and customer base in China, our consolidated growth as a company will be negatively affected and our business, financial condition, results of operations and cash flows may be harmed. BabyCare must comply with significant operational, financial, and other regulatory requirements to engage in direct selling in China. Although we believe that we will be successful in growing BabyCare’s business in China, it is difficult to assess the extent to which BabyCare’s business model and compensation plan will be successful or deemed to be compliant with applicable Chinese laws and regulations. In light of the factors listed above, and the other risks to our business, there can be no assurance that we will be successful in increasing sales and customers in China through BabyCare. 29

Our operations in China are subject to significant government regulation, as well as a variety of legal, political, and economic risks. If the Chinese government modifies its direct selling laws and regulations, or interprets and enforces these laws and regulations in a manner that is adverse to our business in China, our consolidated business and results of operations may be materially harmed. Our operations in China are conducted by BabyCare, our China subsidiary. BabyCare operates in China pursuant to direct selling laws and regulations that are uncertain and evolving. These regulations contain a number of financial and operational restrictions for direct selling companies, including prohibitions on pyramid selling and multi-level compensation. The laws and regulations are also subject to discretionary interpretation and enforcement by various state, provincial and municipal level officials in China. Regulators in China may modify current direct selling laws and regulations or change how they interpret and enforce them. As a result, there can be no assurance that the Chinese government’s current or future interpretation and application of existing and new regulations will not negatively impact our business in China, result in regulatory investigations or lead to fines or penalties against us or our Associates. The Chinese government also exercises significant control over the Chinese economy, including through controlling capital, foreign currency exchange, foreign exchange rates, and tax regulations, providing preferential treatment to certain industry segments or companies and issuing required licenses to conduct business. We also face additional risks resulting from new and expanded China data privacy and security laws and regulations. Accordingly, any adverse change in the Chinese governmental, economic or other policies could have a material adverse effect on BabyCare’s business in China and our consolidated results of operations. In addition to BabyCare's direct selling business in China, we periodically offer and sell certain U.S. products in China through a cross-border e-commerce sales channel by utilizing one of our separate China subsidiaries that is registered to engage in cross-border e-commerce. This cross-border e-commerce channel is legally required to be separate from BabyCare's direct selling business in China. The products that we offer and sell through this channel are neither registered for retail sale in China nor registered as direct selling products under BabyCare's direct selling license. Consequently, products sold via our cross-border e-commerce channel can only be sold to China customers for their personal consumption and cannot be sold through BabyCare's direct selling channel. BabyCare's direct selling business in China could be negatively impacted if China regulatory authorities (i) attribute our cross-border e-commerce sales and related product claims to BabyCare's direct selling business, and (ii) make a determination that the same are in violation of direct selling or other applicable laws and regulations. Although BabyCare utilizes a business model that has been developed specifically for China’s laws and regulations, the Chinese government has not approved BabyCare’s model, compensation plan, and operations. BabyCare’s business model has been designed specifically for China’s laws and regulations based on, among other things, BabyCare’s (i) communications with the Chinese government, (ii) interpretation of the direct selling laws and regulations, as well as its understanding of how the government interprets and enforces the regulations, and (iii) understanding of how other multinational direct selling companies operate in China. Many of the components of BabyCare’s business model are unique to China and are not part of our business model in our markets outside of China. For example, BabyCare sells products in China through a variety of methods, including: (a) online through its website; (b) at physical branch retail locations in China; (c) through direct sellers in provinces and municipalities where BabyCare has received a direct selling license; and (d) through independent distributors who are considered independent business owners under Chinese law. BabyCare has not received confirmation from the Chinese government that its business model and operations in China comply with applicable laws and regulations, including those pertaining to direct selling. We cannot assure that Chinese regulatory authorities would deem BabyCare's business model, compensation plan or the activities of its employees, direct sellers or independent distributors to be compliant with current or future laws and regulations. If BabyCare’s model were deemed to be in violation of applicable regulations, as they are now or may in the future be interpreted or enforced, BabyCare could be subject to fines, penalties or suspension of its business in China or, ultimately, have its direct selling license revoked by the Chinese government, all of which could have a material adverse impact on our business in China. BabyCare’s operations in China, and direct selling companies in general, are subject to significant government oversight, scrutiny and monitoring. Chinese regulators regularly monitor and make inquiries about the business activities of direct sellers in China and have done so with BabyCare. For example, following adverse media coverage of certain health product companies and direct selling companies in 2019, several departments of the Chinese government, including SAMR, MPS, and MOFCOM, initiated a review of health product and direct selling companies in China. The review required applicable companies such 30

as BabyCare to conduct a self-assessment of the regulatory compliance of their business and to provide information to the government regarding the same. The review also entailed a review of a company’s regulatory compliance by various departments of the Chinese government. During this review, the Chinese government, among other things, (i) instructed direct selling companies not to hold large distributor meetings, and (ii) suspended its application review process for direct selling licenses and authorizations. The Chinese government has yet to re-open the application review process for direct selling licenses and authorizations or indicate if or when it plans to do so. Direct selling regulations in China prevent persons who are not Chinese nationals from engaging in direct selling in China. We have implemented internal policies that are designed to promote our Associates’ compliance with these regulations, however, we cannot guarantee that any of our Associates residing outside of China or any of BabyCare’s Associates in China have not engaged or will not engage in activities that violate our policies in this market or that violate Chinese law or other applicable laws and regulations, which might result in regulatory action and adverse publicity and potential harm to our business in China. The Chinese government has investigated and imposed significant fines on companies and their distributors believed to have violated direct selling and anti-pyramiding regulations. In some cases, it has even shut such companies down. There have been instances where inquiries or complaints about BabyCare’s business have resulted in warnings from the Chinese government as well as the payment of fines by BabyCare or its distributors. We expect that BabyCare will continue to face the risk of government inquiries, complaints or investigations. Any determination that BabyCare’s business or the activities of its Associates are not in compliance with applicable regulations could result in additional fines, disruption of business, or the suspension or termination of BabyCare’s licenses, including its direct selling licenses, all of which could have a material adverse effect on our business and operations. There can be no assurance that the Chinese government’s interpretation and enforcement of applicable laws and regulations will not negatively impact BabyCare’s business, result in regulatory investigations or lead to fines or penalties against BabyCare, USANA or our Associates in China. BabyCare must apply for and receive government approval to expand its business in China and the failure to obtain such approvals could negatively impact its ability to expand and grow its business. BabyCare has obtained direct selling licenses in certain provinces and municipalities and it must obtain various licenses and approvals from additional municipalities and provinces within China if it is to operate its direct selling business model in China. Although direct selling licenses are centrally issued, the licenses are generally valid only in the jurisdictions within which related approvals have been obtained. Those approvals are generally awarded on local and provincial bases, and the approval process requires involvement of multiple ministries at each level. BabyCare also will be required to obtain licenses from municipalities and provinces within China where it currently does not hold a license. The Chinese government has not reopened its application review process for direct selling licenses and approvals since suspending the process in 2019. If BabyCare is unable to obtain additional direct selling licenses and approvals as quickly as we would like, or at all, it would negatively impact our ability to expand and grow our business in China. Ultimately, there can be no assurance that BabyCare will be successful in maintaining its current direct selling licenses or obtaining additional direct selling licenses or the required approvals to expand into additional locations in China that are important to its business. Risk Associated with Our International Operations Risks associated with operating in international markets could restrict our ability to expand globally and harm our business and prospects. We currently conduct our business in various foreign countries, and we expect to expand the number of countries in which we operate in the future. Economic conditions, including those resulting from wars, civil unrest, political unrest, acts of terrorism and other conflicts or volatility in the global markets, may adversely affect our customers, their demand for our products and their ability to pay for our products. In addition, there are numerous risks inherent in conducting our business internationally, including, but not limited to, potential instability in international markets, changes in regulatory requirements applicable to international operations, currency fluctuations in foreign countries, political, economic and social conditions in foreign countries and complex U.S. and foreign laws and treaties. We believe that our ability to achieve future growth is dependent in part on our ability to continue our international expansion efforts. There can be no assurance, however, that we will be able to grow in our existing international markets or enter new international markets on a timely basis, or that new markets will be profitable. We must overcome significant regulatory and legal barriers before we can begin marketing in any international market. In addition, 31

before marketing commences in a new country or market, it is difficult to assess the extent to which our products and sales techniques will be accepted or successful in any given country. In addition to significant regulatory barriers, we may also encounter problems conducting operations in new markets with different cultures and legal systems from those encountered elsewhere. We may be required to reformulate certain of our products before commencing sales in a given country. Once we have entered a market, we must adhere to the regulatory and legal requirements of that market. No assurance can be given that we will be able to successfully reformulate our products in any of our current or potential international markets to meet local regulatory requirements or to attract local customers. Our failure to do so could have a material adverse effect on our business, financial condition, or results of operations. In many market areas, other direct selling companies already have significant market penetration, the effect of which could be to desensitize the local population to a new opportunity, such as USANA, or to make it more difficult for us to attract qualified Associates or sell to customers generally. Even if we are able to commence operations in new markets, there may not be a sufficient population of persons who are interested in our business. Trade policies, disputes, tariffs or other international disputes could harm our business and operating results. Trade policies and actions which have been, or in the future may be, implemented by the United States against other countries, including China, relating to the import and export of certain products, and negotiations with respect thereto, may have a negative effect on our business, financial condition, and results of operations in China and other markets. In 2025, there have been increased, consistent, ongoing discussions and activities from the new U.S. presidential administration that raise concern in this regard. Additionally, any actions taken by the Chinese government, or the government in our other markets, to implement further trade policy changes, financial restrictions, or increased regulatory scrutiny on U.S. companies could negatively impact our business, financial condition, and results of operations. For instance, China has previously taken or threatened to take trade and other actions in retaliation against U.S. policies, and is likely to continue to do so. Past or future developments in this regard may have a material adverse effect on the economies, financial markets, and currency exchange rates in China and the United States. Tensions between the United States and China have increased over the past few years as a result of disputes in areas including trade policy, intellectual property, cybersecurity and data privacy. China is our largest market and the United States is one of our largest markets and the location of our corporate headquarters. Our business could be harmed if relations between the United States and China worsen or if either government imposes additional policies, tariffs or sanctions and our business could encounter increased regulatory scrutiny in China, as well as adverse media or public attention in China, as a result of the deteriorating bilateral relationship. We are subject to various governmental export control and trade sanctions laws and regulations that could impair our ability to compete in international markets or subject us to liability if we violate these controls. In some cases, our products are subject to export control laws and regulations, including the Export Administration Regulations administered by the U.S. Department of Commerce, and our activities may be subject to trade and economic sanctions, including those administered by the United States Department of the Treasury’s Office of Foreign Assets Control, or OFAC (collectively, “Trade Controls”). As such, a license may be required to export or re-export our products, or provide related services, to certain countries and end-users, and for certain end-uses. The process for obtaining necessary licenses may be time-consuming or unsuccessful, potentially causing delays in sales or losses of sales opportunities and these licenses may not be issued. Trade Controls are complex and dynamic regimes and monitoring and ensuring compliance can be challenging. Although we have procedures in place designed to ensure our compliance with Trade Controls, any failure to comply could subject us to both civil and criminal penalties, including substantial fines, possible incarceration of responsible individuals for willful violations, possible loss of our export or import privileges, and reputational harm. Although we have no knowledge that our activities have resulted in violations of Trade Controls, any failure by us or our partners to comply with applicable laws and regulations could have negative consequences for us, including reputational harm, government investigations, and penalties. Fluctuation in the value of currency exchange rates with the U.S. dollar affects our operations and our net sales and earnings. For the year ended December 28, 2024, 89.3% of our total net sales were generated in markets outside of the United States. Consequently, exchange rate fluctuations have, and will continue to have, a significant effect on our sales 32

and earnings. If exchange rates fluctuate dramatically, it may become uneconomical for us to establish or to continue activities in certain countries. For instance, changes in currency exchange rates may affect the relative prices at which we and our competitors sell similar products in the same market. As our business expands outside the United States, an increasing share of our net sales and operating costs is transacted in currencies other than the U.S. dollar. Accounting practices require that our non-U.S. financial results be converted to U.S. dollars for reporting purposes. Consequently, our reported net earnings may be significantly affected by fluctuations in currency exchange rates, with earnings generally increasing with a weaker U.S. dollar and decreasing with a strengthening U.S. dollar. Currently our strategy for reducing our exposure to currency fluctuation includes the timely and efficient repatriation of earnings from international markets where such earnings are not considered to be indefinitely reinvested, and settlement of intercompany transactions. We also enter into currency exchange contracts to offset foreign currency exposure in various international markets. We do not use derivative instruments for speculative purposes. A foreign government may impose, and some have imposed, foreign currency remittance restrictions. For example, several markets in which we conduct business, including China, require that we file the necessary statutory financial statements for the relevant period as a prerequisite to repatriating cash in the form of a dividend. Any government restrictions on transfers of cash out of the country and control of exchange rates may have a materially adverse effect on our business, financial condition, liquidity and cash flows. There can be no assurance that we will be successful in protecting our operating results or cash flows from potentially adverse effects of currency exchange fluctuations. Any such adverse effects could also adversely affect our business, financial condition, or results of operations. Inflationary pressures and persistently high prices and uncertain availability of commodities, raw materials or other inputs used by us and our suppliers, or instability in logistics and related costs, could negatively impact our profitability. Increases in prices, including as a result of inflation and rising interest rates, for commodities, raw materials or other inputs that we and our suppliers use in manufacturing products, systems, components and ingredients or other similar raw materials, or increases in logistics and related costs, have led and may continue to lead to higher costs for our products. In addition, any increase in the cost, or reduced availability, of critical materials for our products could lead to higher production costs and could impede our ability to successfully deliver on business strategy. Further, increasing global demand for, and uncertain supply of, such materials could disrupt us or our suppliers’ ability to obtain such materials in a timely manner and/or could lead to increased costs. Geopolitical risk, fluctuations in supply and demand, fluctuations in interest rates, any weakening of the U.S. dollar and other economic and political factors have created and may continue to create pricing pressure for commodities, raw materials and other inputs. These inflationary pressures could, in turn, negatively impact our profitability because we may not be able to pass all of those costs on to our customers or require our suppliers to absorb such costs. Additionally, any price increases we impose on our products as a result of the inflationary environment may result in decreased demand of our products, which could adversely affect our business, financial condition, or results of operations. Risks Related to Our Products, Manufacturing and Operations Our products and manufacturing activities are subject to extensive government regulation, which could limit or prevent the sale of our products in some markets. The manufacture, packaging, labeling, advertising, promotion, distribution, and sale of our products are subject to regulation by numerous national and local governmental agencies in the United States and other countries, including the FDA and the FTC. Failure to comply with FDA regulatory requirements may result in, among other things, injunctions, product withdrawals, recalls, product seizures, fines, and criminal prosecutions. Any action of this type by the FDA could materially adversely affect our ability to market our products successfully. The manufacture of nutritional or dietary supplements and related products in the United States requires compliance with dietary supplement GMPs, which are based on the food-model GMPs, with additional requirements that are specific to dietary supplements. We believe our manufacturing processes comply with these GMPs for dietary supplements. Nevertheless, any FDA action determining that our processes were non-compliant with dietary supplement GMPs, could materially adversely affect our ability to manufacture and market our products. In addition, the Dietary Supplement & Nonprescription Drug Consumer Protection Act requires manufacturers of dietary supplement and over-the-counter products to notify the FDA when they receive reports of serious adverse events occurring within the United States. Potential FDA responses to any such report could include injunctions, product withdrawals, recalls, product seizures, fines, or criminal prosecutions. We have an internal adverse event reporting system that has been in place for several years and believe that we comply with this new law. Nevertheless, any action by the FDA in response to a serious adverse event report that may be filed by us could materially and adversely affect our ability to market our products successfully. 33

In markets outside the United States, prior to commencing operations or marketing our products, we may be required to obtain approvals, licenses, or certifications from a country’s ministry of health or a comparable agency. Approvals or licensing may be conditioned on reformulation of products or may be unavailable with respect to certain products or product ingredients. We must also comply with product labeling and packaging regulations that vary from country to country. These activities are also subject to regulation by various agencies of the countries in which our products are sold. We cannot predict the nature of any future laws, regulations, interpretations, or applications, nor can we determine what effect additional governmental regulations or administrative orders, when and if promulgated, could have on our business. These potential effects could include, however, requirements for the reformulation of certain products to meet new standards, the recall or discontinuance of certain products, additional record keeping and reporting requirements, expanded documentation of the properties of certain products, expanded or different labeling, or additional scientific substantiation. Any or all of these requirements could have a material adverse effect on our business, financial condition, or results of operations. Our in-house manufacturing activity is subject to certain risks. We manufacture approximately 69% of the products sold to our customers. Additionally, over the past several years we have increased self-manufacturing of our foods, personal care and skincare products, which has increased the percentage of products we manufacture in-house. Because of our self-manufacturing practices, we are dependent upon the uninterrupted and efficient operation of our manufacturing facilities. Those operations are subject to power failures, the breakdown, failure, or substandard performance of equipment, the improper installation or operation of equipment, natural or other disasters, and the need to comply with the requirements or directives of government agencies, including the FDA and CFDA. There can be no assurance that the occurrence of these or any other operational problems at our facilities would not have a material adverse effect on our business, financial condition, or results of operations. We are subject to a variety of environmental laws relating to the storage, discharge, handling, emission, generation, manufacture, use and disposal of chemicals, solid and hazardous waste, and other toxic and hazardous materials. Our manufacturing operations presently do not result in the generation of material amounts of hazardous or toxic substances. Nevertheless, complying with new or more stringent laws or regulations, or more vigorous enforcement of current or future policies of regulatory agencies, could require substantial expenditures by us that could have a material adverse effect on our business, financial condition, or results of operations. Environmental laws and regulations require us to maintain and comply with a number of permits, authorizations, and approvals and to maintain and update training programs and safety data regarding materials used in our processes. Violations of those requirements could result in financial penalties and other enforcement actions and could require us to halt one or more portions of our operations until a violation is cured. The combined costs of curing incidents of non-compliance, resolving enforcement actions that might be initiated by government authorities, or of satisfying new legal requirements could have a material adverse effect on our business, financial condition, or results of operations. Our reliance on third parties to manufacture and supply certain of our products may harm our business, financial condition and operating results. We contract with third-party suppliers and manufacturers for the production of certain of our products, which accounted for approximately 31% of our product sales for the year ended December 28, 2024. These third-party suppliers and manufacturers produce and, in most cases, package the products according to formulations and specifications that have been developed by or in conjunction with our in-house product development team. These products include most of our gelatin-capsulated supplements, Rev3 Energy Drink, Probiotic, our powdered drink mixes, foods, and certain of our personal care products, including our Celavive line for markets outside of China. Hiya also utilizes third-party manufacturers for their products. Products manufactured by third-party suppliers at their locations must also pass through quality control and assurance procedures to ensure they are manufactured in conformance with our specifications. We cannot assure you that our outside contract manufacturers will continue to reliably supply products to us at the levels of quality, or the quantities, we require, and in compliance with our specifications or applicable laws, including under the FDA’s GMP regulations. We have encountered situations in the past where we have had disagreements with contract manufacturers about the overall quality of products they have produced for us, and specifically whether such products conform to our specifications. We have also suspended and terminated relationships with contract manufacturers for quality issues and non-conforming products. While our business continuation plan contemplates events such as these, identifying and obtaining acceptable replacement manufacturing sources, on a timely basis or at all, is challenging. Additionally, transferring our third-party manufacturing business to another contract manufacturer can be expensive, time-consuming, 34

result in delays in our production or shipping, reduce our net sales, damage our relationship with customers and damage our reputation in the marketplace. The inability to obtain adequate supplies of raw materials for products at favorable prices, or at all, could have a material adverse effect on our business, financial condition, or operating results. We acquire all of our raw materials for the manufacture of our products from third-party suppliers. Materials used in manufacturing our products are purchased through purchase order, often invoking pre-negotiated annual supply agreements. We have very few long-term agreements for the supply of these materials. There is a risk that any of our suppliers could discontinue selling raw materials to us. Although we believe that we could establish alternate sources for most of our products, any delay in locating and establishing relationships with other sources could result in product shortages or back orders for products, with a resulting loss of net sales. In certain situations, we may be required to alter our products or to substitute different products from another source. There can be no assurance that suppliers will provide the raw materials that are needed by us in the quantities that we request or at the prices that we are willing to pay. Because we do not control the actual production of certain raw materials, we are also subject to delays caused by any interruption in the production of these materials, based on conditions not within our control, including those related to the COVID-19 pandemic, weather, crop conditions, transportation interruptions, strikes by supplier employees, and natural disasters (the nature and severity of which may be impacted by climate change) or other catastrophic events. In the past, we have experienced temporary shortages of the raw materials used in certain of our nutritional products. Although we had identified multiple sources to supply such raw material ingredients, quantities of the materials we purchased during these shortages were at higher prices, which had a negative impact on our gross margins for those products. While we periodically experience price increases due to unexpected raw material shortages and other unanticipated events, we have been able to manage this by increasing the price at which we sell our products, therefore, this has historically not resulted in a material effect on our gross margin. Supply chain interruptions, including as a result of shortages and transportation issues or unexpected increases in demand, and price increases can adversely affect us as well as our suppliers and Associates, whose performance may have a significant impact on our results. Such shortages or disruptions could be caused by factors beyond the control of our suppliers, Associates or us. Any of these events, if they were to occur, could harm our business, results of operations and financial condition. Delays and disruptions to transporting and distributing our products may adversely affect our results. We may experience delays and disruptions in shipping, transporting and otherwise distributing our products, including increased airport and shipping port congestion, a lack of transportation capacity, increased expenses, import or export controls or delays, and labor disputes or shortages. Disruptions in transportation and shipments may result in increased costs, including the additional use of airfreight to meet demand. Congestion to ports can affect previously negotiated contracts with shipping companies, resulting in unexpected increases in shipping costs and reduction in our profitability. For example, the COVID-19 pandemic resulted in several delays, cost increases, and disruptions in our global distribution channel. We may incur liability with respect to our products. As a manufacturer and a distributor of products for human consumption and topical application, we could become exposed to product liability claims and litigation. Additionally, the manufacture and sale of these products involves the risk of injury to consumers due to tampering by unauthorized third parties or product contamination. To date, we have not been a party to any product liability litigation, although, like any dietary supplement company, we have received reports from individuals who have asserted that they suffered adverse consequences as a result of using our products. The number of reports we have received to date is nominal. These matters historically have been settled to our satisfaction and have not resulted in material payments. We are aware of no instance in which any of our products are or have been defective in any way that could give rise to material losses or expenditures related to product liability claims. Although we maintain product liability insurance, which we believe to be adequate for our needs, there can be no assurance that we will not be subject to such claims in the future or that our insurance coverage will be adequate. Nutritional supplement products may be supported by only limited availability of conclusive clinical studies. Our products include nutritional supplements that are made from vitamins, minerals, herbs, and other substances for which there is a long history of human consumption. Some of our products contain innovative ingredients or combinations of ingredients. Although we believe that all of our products are safe when taken as directed, there is little long-term experience with human consumption of certain of these product ingredients or combinations of ingredients in concentrated form. We conduct research and test the formulation and production of our products, but we have performed or 35

sponsored only limited clinical studies. Furthermore, because we are highly dependent on consumers’ perception of the efficacy, safety, and quality of our products, as well as similar products distributed by other companies, we could be adversely affected in the event that those products prove or are asserted to be ineffective or harmful to consumers or in the event of adverse publicity associated with any illness or other adverse effects resulting from consumers’ use or misuse of our products or similar products of our competitors. Legal, Regulatory, Compliance and Tax Risks Legal action by former Associates or third parties against us could harm our business. We continually monitor and review our Associates’ compliance with our policies and procedures as well the laws and regulations applicable to our business. In the ordinary course of our business, Associates occasionally fail to adhere to our policies and procedures. If this happens, we may take disciplinary action against the breaching Associate. This disciplinary action is based on the facts and circumstances of the particular case and may include anything from warnings for minor violations to termination of the Associate’s purchase and distribution rights for more serious violations. From time to time, we become involved in litigation with an Associate whose purchase and distribution rights have been terminated. We consider this type of litigation to be routine and incidental to our business. While neither the existence nor the outcome of this type of litigation is typically material to our business, in the past we have been involved in litigation of this nature that resulted in a large cash award against us. Our competitors have also been involved in this type of litigation, and more and more of these cases have resulted in class action litigation, where the result has been a large cash award against the competitor or a large cash settlement by the competitor. These types of challenges, awards or settlements could provide incentives for similar actions by other former Associates against us in the future, which could result in class action litigation against us. Any such challenge involving others in our industry or us, could harm our business by resulting in fines or damages against us, creating adverse publicity about us or our industry, or hurting our ability to attract and retain customers. We believe that Associate compliance is critical to the integrity of our business, and, therefore, we will continue to be assertive in ensuring that our Associates comply with our policies and procedures. As such, there can be no assurance that this type of litigation will not occur again in the future or result in an award or settlement that has a materially adverse effect on our business. We could also be subject to challenges by private parties in civil actions. We are aware of recent civil litigation against various direct selling companies in the United States, which have already resulted in settlements and may result in additional significant settlements in the future by these companies. There can be no assurance that we will not be challenged by private parties in litigation. We may incur liability under our “Athlete Guarantee” program. We believe that our nutritional supplement products are free from substances that have been banned by world- class training and competitive athletic programs. We retain independent testing agencies to conduct periodic checks for banned substances. We further believe that, while our products promote good health, they are not otherwise considered “performance enhancing” as that term has been used in defining substances that are banned from use in international competition by the World Anti-Doping Agency (“WADA”). For many years, we have been a sponsor of Olympic level athletes and professional competitors around the world. These athletes have been tested on many occasions and have never tested positive for banned substances as a result of taking USANA nutritional products. To back up our claim that athletes who use USANA products as part of their training regimen will not be consuming banned substances, we have offered to enter into agreements with select athletes, some of whom have high-profiles and are highly compensated. These agreements provide that, during the term of the agreement, should the athlete test positive for a banned substance included in the WADA, and should such positive result be caused by taking USANA nutritional products, we will compensate that athlete at an amount equal to two times their current annual earnings, up to $1.0 million, based on the athlete’s personal level of competition, endorsement, and other income, as well as other factors. Although we believe that the pool of current and potential participants in the program is small and that the procedures and safeguards implemented by us in connection with the program are sound, there is no guarantee that an athlete who is accepted in the program will not successfully make a claim against us. We currently have no insurance to protect us from potential claims under this program. Failure to comply with anti-corruption laws could adversely affect our business. We currently conduct our business in various foreign countries and expect to expand the number of countries in which we operate in the future. Our international business is subject to various anti-corruption laws, including principally the U.S. Foreign Corrupt Practices Act ("FCPA"). In recent years, there have been an increasing number of investigations and other enforcement activities under these laws, including a voluntary investigation we concluded several years ago 36

concerning our China operations. The FCPA prohibits U.S.-based companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or retaining business. Other anti-corruption laws prohibit both domestic and international bribery as well as bribery across both public and private sectors. We pursue opportunities in certain parts of the world that experience government corruption and in certain circumstances compliance with anti-bribery laws may conflict with local customs and practices. Our policies mandate compliance with all applicable anti-bribery laws. Further, we require our partners, subcontractors, agents and others who work for us or on our behalf to comply with these and other anti-bribery laws. Although we have policies and procedures and a compliance program designed to ensure that we comply with the FCPA and other anti-bribery laws, there is no assurance that such policies or procedures will protect us against liability under the FCPA or other laws for actions taken by our agents, employees and intermediaries. If we are found to be liable for violations of these acts (either due to our own acts or our inadvertence or due to the acts or inadvertence of others), we could incur severe criminal or civil penalties or other sanctions, which could have a material adverse effect on our reputation, business, results of operations or cash flows. In addition, detecting, investigating and resolving actual or alleged violations of these acts is expensive and could consume significant time and attention of our senior management. We could be subject to adverse changes in tax laws, regulations and interpretations or challenges to our tax positions. We are subject to tax laws and regulations in the United States and numerous other foreign jurisdictions. Tax laws, regulations, and interpretations in various jurisdictions may change, with or without notice, due to social, economic, political and other considerations. As a result, our evaluation and estimates for our provision for income taxes may change perhaps negatively. Our future effective tax rates could be affected by numerous factors, including changes in the market mix for our net sales, the amount of our earnings and where earned, intercompany transactions, the inability to realize tax benefits, changes in currency exchange rates, tax positions, allocation and apportionment of state taxes, changes in our deferred tax assets and liabilities and their valuation, changes in our business operations, acquisitions, and entry into new markets. There can be no assurance that additional changes in tax laws or regulations, both within the United States and the other jurisdictions in which we operate, will not materially and adversely affect our effective tax rate, tax payments, financial condition and results of operations. Similarly, changes in tax laws and regulations that impact our customers and counterparties or the economy generally may also impact our financial condition and results of operations. We are also subject to examination by tax authorities, including state revenue agencies and foreign governments. While we regularly assess the likelihood of favorable or unfavorable outcomes resulting from examinations by tax authorities to determine the adequacy of our provision for income taxes, there can be no assurance that the actual outcome resulting from these examinations will not materially adversely affect our financial condition and operating results. The IRS and several foreign tax authorities have also increasingly focused attention on intercompany transfer pricing. Tax authorities, in certain instances, have disagreed with our transfer pricing calculations and agreements and assessed us with additional taxes. Going forward, tax authorities could continue to disagree with our intercompany charges, cross- jurisdictional transfer pricing or other matters and assess additional taxes. If we do not prevail in any such disagreements, our profitability may be affected. Tax laws and regulations are complex and subject to varying interpretations and any significant failure to comply with applicable tax laws and regulations in all relevant jurisdictions could give rise to substantial penalties and liabilities. Any changes in enacted tax laws, rules or regulatory or judicial interpretations; any adverse outcome in connection with tax audits in any jurisdiction; or any change in the pronouncements relating to accounting for income taxes could materially and adversely impact our effective tax rate, tax payments, financial condition and results of operations. If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud. As more fully disclosed in Item 9A. “Controls and Procedures,” in 2024 we concluded that our disclosure controls and procedures were not effective as of December 30, 2023, due to material weaknesses in internal control over financial reporting. The material weaknesses resulted from an insufficient complement of trained resources with specialized skills and knowledge in information technology general controls (ITGCs), or an alternative contingency plan, to timely respond to the impacts of turnover in key personnel with responsibility for ITGCs that occurred during 2023. Although these material weaknesses did not result in any errors to the financial statements, and there were no changes to previously released financial results, the applicable control deficiencies were not remediated as of December 30, 2023, and, consequently, there was a reasonable possibility that it could have resulted in a material misstatement in the Company's financial statements that would not have been detected. 37

The Company’s management, under the oversight of the Audit Committee, has completed a remediation plan for these material weaknesses as described more fully in Item 9A. “Controls and Procedures,” and management has concluded that these material weaknesses have been remediated, that the related controls are effective, and that the Company's disclosure controls and internal control over financial reporting are effective as of December 28, 2024. Going forward, if we fail to maintain effective internal controls, we could be required to take costly and time-consuming corrective measures, to remedy any number of deficiencies, significant deficiencies or material weaknesses, be required to restate the affected historical financial statements, be subjected to investigations and/or sanctions by federal and state securities regulators and be subjected to civil lawsuits by security holders. Any of the foregoing could also cause investors to lose confidence in our reported financial information and in our company and would likely result in a decline in the market price of our stock and in our ability to raise additional financing if needed in the future. Environmental, Social and Governance ("ESG") issues may have an adverse effect on our reputation, business, financial condition or results of operations. Companies across all industries are facing increasing scrutiny relating to their ESG policies. If we are unable to meet our sustainability goals or evolving regulator, investor, industry or stakeholder expectations and standards, or if we are perceived to have not responded appropriately to the continuing concern for ESG issues, customers may choose to stop purchasing our products and our reputation, business or financial condition may be adversely affected. In particular, these constituencies are increasingly focusing on environmental issues, including climate change, water use, plastic waste, and other sustainability concerns. These factors could cause us to incur additional costs, to make changes to our operations to make additional commitments, set targets or establish additional goals and take actions to meet them, which could expose us to market, operational and execution costs or risk. In addition to environmental issues these constituencies are also focused on social and other governance issues, including matters such as, but not limited to, human capital and social issues. We also have established inclusion and belonging goals as part of our ESG initiative. Concern over climate change, including plastics and packaging materials, in particular, may result in new or increased legal and regulatory requirements, including, for example, two climate disclosure laws adopted by California in 2023. Increased regulatory requirements related to environmental causes, and related ESG disclosure rules, including the new California laws and the SEC's disclosure proposal on climate change, may result in increased compliance costs or increased costs of energy, raw materials or compliance with emissions standards, which may cause disruptions in the manufacture of our products or an increase in operating costs. Any failure to achieve our sustainability goals or a perception (whether or not valid) of our failure to act responsibly with respect to the environmental, human capital, or social issues, or to effectively respond to new, or changes in, legal or regulatory requirements concerning environmental or other ESG matters, or increased operating or manufacturing costs due to increased regulation or environmental causes could adversely affect our business and reputation and increase risk of litigation. Risk Associated with Information Technology, Data Security and Data Privacy A failure or interruption of our information technology systems would harm our business. The global nature of our business, shopping and our global compensation plan requires the development and implementation of robust and efficiently functioning information technology systems. Such systems are vulnerable to a variety of potential risks, including damage or interruption resulting from natural disasters, power outages, certain aging system architecture, systems failures, hardware or software corruption, human error or hacking, malware, ransomware, phishing or other similar acts. We rely on both self-developed and third-party developed and supported information technology systems. Although we have adopted and implemented a business continuity and disaster recovery plan and a variety of other operational safeguards, the occurrence of any of these events could result in costly interruptions or failures adversely affecting our business and the results of our operations. We rely on information technology to support our operations and reporting environments. A data breach involving that technology or the data stored in it, could disrupt our ability to operate our businesses effectively, adversely affect our reported financial results and our reputation, and expose us to significant potential liability, government investigations, fines or litigation. In the ordinary course of our global business, we collect and store in our data centers and on our networks, including cloud systems, significant amounts of data, including personally identifiable information (PII), intellectual property, and our proprietary business information. The secure collection, storage and other processing of this information is critical to our operations, regulatory compliance and business strategy. Although we strive to frequently analyze and 38

improve our data security measures, our information technology and infrastructure are subject to persistent attacks of varying degrees and types and we may be vulnerable to attacks by hackers. Such attacks could include viruses, ransomware attacks, computer denial of service attacks, or phishing schemes. In some instances, despite our reasonable efforts, it could take us some time to discover that our networks have been breached. Any such breach of our networks and the information and PII stored therein could cause such information and PII to be accessed, publicly disclosed, altered, damaged, held ransom, lost or stolen. In any such event, we could suffer significant loss or incur significant liability, including: damage to our reputation; increased cyber insurance premiums; loss of customer confidence or goodwill; and significant expenditures of time and money to address and remediate the resulting damage (including notification and credit monitoring costs, as well as fines and penalties imposed by regulators) to affected individuals or business partners, or to defend ourselves in resulting litigation or other legal proceedings, by affected individuals, business partners or regulators. Likewise, a failure to adhere to the payment card industry’s data security standards could lead to significant penalties from payment card associations, termination of our ability to receive credit or debit card payments, any of which could have a material adverse effect on our business and financial condition. Furthermore, such data breach could result in significant disruption of our operations, which could adversely affect our business, revenues and competitive position. Additionally, as we utilize artificial intelligence ("AI") technologies throughout our business, we will encounter an expanded risk landscape, including data security and data privacy risks, unintended biases, discriminatory outputs, and intellectual property risk, all of which could impact our ability to protect our customer information and data and expose us to additional liability. Various U.S. and international jurisdictions have passed laws regulating the use of AI technologies and we believe we will see an increase in regulation in this area, which may impact our ability to use AI technologies throughout our business. We are subject to data privacy and security laws and regulations, and our actual or perceived failure to comply with them could adversely affect our business and operating results. Compliance with data privacy and security laws and regulations is a significant effort for us in all of our markets because we collect, store and otherwise process significant amounts of customer and employee personal information for business (including for transactional and marketing purposes) and legal purposes. The governments of our various markets have adopted, or are adopting, complex and strict laws and regulations governing data privacy and security, and these areas are still rapidly evolving. These laws and regulations have resulted in greater compliance risk and cost for us. These laws and regulations often require us to take a variety of actions, including: implementing new data privacy and security policies; granting individuals a wide variety of rights with respect to their PII, including access, correction and deletion rights; informing individuals of security breaches that affect their PII; disclosing to individuals how we process their PII and obtaining their written consent to such processing; and localizing individuals' PII within national borders and complying with cross border PII transfer assessments and requirements, among other things. Examples of significant, recent data privacy and security laws affecting our various markets include the European Union General Data Protection Regulation, ("GDPR"), China’s national Data Privacy Law and Personal Information Protection Law, China's Cybersecurity Law, Korea’s Personal Information Protection Act, the California Consumer Privacy Act, ("CCPA"), and the California Privacy Rights Act, and other national and state data privacy laws in our various markets. There also is a wide range of enforcement agencies at both the state and national levels in our markets that can review companies for privacy and data security concerns based on general consumer protection laws. The FTC and state Attorneys General all are aggressive in reviewing privacy and data security protections for consumers. We have incurred, and will continue to incur, substantial costs in striving to comply with these various data privacy and security laws and regulations. Compliance with these laws and regulations may limit our ability to provide products and services to our customers that they may find valuable or otherwise require us to change our business practices in a manner that is ultimately adverse to our business objectives. As such, we cannot assure ongoing compliance with all such laws or regulations, industry standards, contractual obligations and other legal obligations. Any failure or perceived failure by us to comply with data security and privacy laws and regulations may result in governmental enforcement actions and prosecutions, private litigation, significant fines and penalties, adverse publicity, or reputation damage, which could have an adverse effect our business and operating results. 39

Human Capital Risks Associated with our Business If we are unable to attract and retain active Associates and Preferred Customers, our business may be harmed. Our consumer base includes Associates who personally consume and sell our products, Preferred Customers who join USANA and simply consume our products, and retail customers who do not join USANA but purchase products directly from us or one of our Associates and consume our products. We refer to Associates, and Preferred Customers in this Annual Report together as active Customers. We rely largely on our Associates to market and sell our products and to generate active Customer growth. Our ability to maintain and increase sales in the future will depend in large part upon our success in increasing our number of active Customers. Our success will also depend on our ability to retain and motivate our existing Associates and attract new Associates to sell our products. Associates typically market and sell our products on a part-time basis and often engage in other business activities, some of which may compete with us. Our ability to continue to attract and retain active Customers can be affected by a number of factors, some of which are beyond our control, including each of the other risks identified in this Annual Report. Our Associates may terminate their services at any time and, like most direct selling companies, we experience a high turnover among new active Customers from year to year. Customers may also stop buying from us at any time and it is challenging to determine why a customer actually stops buying. In 2023 most of our markets, including China, experienced active Customer declines. If our strategies, including our customer experience strategy, do not generate growth in our active Customer base, our operating results could be harmed. We also rely on the successful efforts of our Associates who become leaders with our Company. Our Compensation Plan is designed to permit Associates to sponsor new Associates and Preferred Customers, thereby creating sales organizations. As a result, Associates develop business and personal relationships with other Associates and Preferred Customers. The loss of a key Associate or group of Associates, large turnover or decreases in the size of the key Associate force, seasonal or other decreases in product purchases, sales volume reduction, the costs associated with training new Associates, and other related expenses may adversely affect our business, financial condition, or results of operations. Hiya's ability to increase sales in the future will also depend in large part upon their success in increasing their number of subscribers and their ability to retain subscribers. If Hiya's strategies do not generate growth in subscribers, our operating results could be harmed. The loss of key management personnel could adversely affect our business. Our executive officers are primarily responsible for our day-to-day operations, and we believe our success depends in part on our ability to retain our executive officers, to compensate our executive officers at attractive levels, and to continue to attract additional qualified individuals to our management team. We depend upon the services of our Executive Chairman, Kevin Guest; our Chief Executive Officer and President, Jim H. Brown; and our Chief Financial Officer, Douglas Hekking, as well as other key members of our executive team. We cannot guarantee continued service by our key executive officers. We do not maintain key man life insurance on any of our executive officers, nor do we have an employment agreement with any of our executive officers. The loss or limitation of the services of any of our executive officers or the inability to attract additional qualified management personnel could have a material adverse effect on our business, financial condition, or results of operations. Risks Associated with Business Development Activities and Acquisitions Growth through acquisitions is part of our strategy, and we may not successfully integrate, operate or realize the anticipated benefits of our acquisitions. Our growth strategy contemplates acquiring additional businesses, such as the Hiya Acquisition that we completed during 2024 and the two businesses we acquired in 2022. We may acquire additional businesses in the future to the extent that we find prospects that meet our acquisition criteria. Our acquisition criteria includes, but is not limited to: vertical integration; product and category expansion; channel expansion; geographic expansion; and other opportunities that strengthen, diversify and grow our world-wide business. Our completed and potential future acquisitions entail a variety of risks and uncertainties, including: (i) potential disruption to our direct selling business; (ii) failure to achieve our strategic objectives, efficiencies, and growth strategies for the acquisition; (iii) potential loss of key employees, customers, or other stakeholders of acquired businesses, particularly given that our strategy contemplates our acquired businesses operating and growing independently of USANA; (iv) general risks associated with owning and overseeing businesses and industries where we have limited or no prior experience; (v) expense and indebtedness, including unanticipated liabilities and litigation; (vi) shareholder dilution; (vii) difficulty in implementing an effective control environment for acquired 40

companies, in a timely and efficient manner; or (viii) the failure to consummate transactions in a timely or efficient manner or at all. The occurrence of any of the foregoing risks or others, or our inability to effectively execute our business development strategy, could have a material adverse effect on our business, financial condition and operating results. We cannot assure you that we will be able to identify suitable acquisition prospects, consummate acquisitions on favorable terms or at all, or accomplish the objectives of an acquisition. The Hiya Acquisition may not be accretive, and may be dilutive, to our earnings per share, which may negatively affect the market price of our common stock. The Hiya Acquisition is not currently accretive to our earnings per share on a GAAP basis. Our expectations regarding the timeframe in which the Hiya Acquisition may become accretive to our earnings per share, excluding the impact of purchase accounting, may not be realized. In addition, we could fail to realize all of the benefits anticipated in the Hiya Acquisition or experience delays or inefficiencies in realizing such benefits. Such factors could result in the Hiya Acquisition continuing to be dilutive to our earnings per share, which could negatively affect the market price of our common stock. Although we expect that the Hiya Acquisition will result in synergies and other benefits to us, we may not realize those benefits because of challenges inherently associated with integration, performance and the achievement of synergies. The Company and Hiya were operated independently until completion of the Hiya Acquisition, and there can be no assurances that our businesses can be combined in a manner that allows for the achievement of substantial benefits. If we are delayed or not able to successfully integrate Hiya’s businesses with ours, pursue our Hiya direct-to-consumer strategy successfully, or realize the strategic value of the Hiya assets, the anticipated benefits and cost savings of the Hiya Acquisition may not be realized fully or may take longer than expected to be realized. Further, it is possible that there could be loss of key employees, loss of customers, disruption of ongoing businesses or unexpected issues, higher than expected costs and an overall post-acquisition process that takes longer than originally anticipated. Specifically, the following issues, among others, must be addressed in the integration of Hiya businesses in order to realize the anticipated benefits of the Hiya Acquisition so the combined company performs as we hope: • combining certain of the companies’ business functions; • combining certain aspects of the businesses of the Company and Hiya in a manner that permits us to achieve the synergies anticipated to result from the Hiya Acquisition, the failure of which would result in the anticipated benefits of the Hiya Acquisition not being realized in the time frame currently anticipated or at all; • maintaining existing agreements with customers, manufacturers, distributors, talent and vendors and avoiding delays in entering into new agreements with prospective customers, distributors, manufacturers, talent and vendors; • possible inconsistencies in standards, controls, procedures and policies, and compensation structures between Hiya’s structure and our structure; • determining whether and how to address possible differences in company cultures and management philosophies; • integrating the companies’ administrative and information technology infrastructure; and • developing products and technology that allow value to be unlocked in the future. The Hiya Acquisition was consummated in December 2024 and integration activities have only recently commenced. The pursuit of the Hiya Acquisition, preparation for the integration of Hiya and the integration of Hiya have required the time and attention of USANA and Hiya management and other internal resources and the integration of Hiya may continue to do so. This may disrupt our ongoing business and the business of the combined company. The Hiya Acquisition and integration may result in additional costs and expenses. We have incurred and expect to continue to incur significant costs, expenses and fees for professional services and other transaction costs in connection with the Hiya Acquisition and integration. We may also incur accounting and other costs in the integration of the businesses of Hiya that were not anticipated at the time of the acquisition, including costs for which we have established reserves or which may lead to reserves in the future. Such costs could negatively impact the Company’s free cash flow. The Hiya Acquisition may be viewed negatively by our Associates. 41

The Hiya Acquisition and our expansion into new businesses may be viewed negatively by some of our Associates as Hiya sells products that are similar to, and potentially competitive with, those of our direct selling business and may be perceived as utilizing disproportionate resources for business that does not relate to direct selling. These perspectives of our Associates could have a material negative impact on the number or productivity of our Associates and result in a reduction in our net sales or active Customer counts. General Economic, Publicity, Competitive, and Intellectual Property Risks Associated with our Business Difficult economic conditions may adversely affect our business. Over the past few years, economic conditions in many of the markets where we sell our products have resulted in challenges to our business and economies around the world have been negatively impacted by the COVID-19 pandemic. We cannot predict whether world or market-specific economies will improve or deteriorate in the future. If difficult economic conditions continue or worsen, we could experience declines in net sales, profitability and cash flow due to lower demand for our products or other factors caused by economic challenges faced by our customers, potential customers or suppliers. Additionally, these conditions may result in a material adverse effect on our liquidity and capital resources or otherwise negatively impact our operations or overall financial condition. Our business is subject to the effects of adverse publicity and negative public perception. Our ability to attract and retain active Customers and to sustain and enhance sales through our Associates can be affected by adverse publicity or negative public perception regarding our industry, our competition, or our business generally. Our business prospects, financial condition and results of operations could be adversely affected if our public image or reputation were tarnished by negative publicity. This negative public perception may include publicity regarding the legality of direct selling, the quality or efficacy of nutritional supplement products or ingredients in general or our products or ingredients specifically, data privacy or security concerns, and regulatory investigations, regardless of whether those investigations involve us or our Associates or the business practices or products of our competitors or other direct selling companies. There has been significant media and short-seller attention regarding the viability and legality of direct selling in the United States, China, and internationally over the past several years. This attention has led to intense public scrutiny of the industry, as well as volatility in our stock price and the stock price of companies similar to ours. There can be no assurance that we will not be subject to adverse publicity or negative public perception in the future or that such adverse publicity will not have a material adverse effect on our business, financial condition, or results of operations. Our business is subject to the risks associated with intense competition from larger, wealthier, and more established competitors. We face intense competition in the business of distributing and marketing nutritional supplements, vitamins and minerals, personal care products, and other nutritional products, as described in greater detail in “Business — Competition.” Numerous manufacturers, distributors, and retailers compete actively for consumers and, in the case of other direct selling companies, for Associates. Additionally, our failure to develop and utilize AI technology throughout our business could negatively impact our competitive position in the market. AI technology is playing a greater role in product development, operational efficiency, shopping experience, customer engagement, and overall marketing. Our business could be harmed if we are unable to adopt and utilize these technologies as quickly or efficiently as our competition. There can be no assurance that we will be able to compete in this intensely competitive environment. In addition, nutrition and personal care products can be purchased in a wide variety of channels of distribution, including retail stores. Entry to market is not particularly capital intensive or otherwise subject to high barriers and as a result, new competitors can enter easily and compete with us for customers and distributors, including our Associates. Our product offerings in each product category are also relatively small, compared to the wide variety of products offered by many of our competitors. Our business is subject to particular intellectual property risks. Most of our products are not protected by patents. The labeling regulations governing our nutritional supplements require that we indicate ingredients of such products precisely and accurately on product containers. Accordingly, patent protection for nutritional supplements often is impractical given the large number of manufacturers who produce nutritional supplements having many active ingredients in common. Additionally, the nutritional supplement industry is characterized by rapid change and frequent reformulations of products, as the body of scientific research and literature refines current understanding of the application and efficacy of certain substances and the interactions among various substances. We 42

protect our investment in research, as well as the techniques we use to improve the purity and effectiveness of our products, by relying on trade secret laws. We have also entered into confidentiality agreements with certain of our employees involved in research and development activities. Additionally, we endeavor to seek, to the fullest extent permitted by applicable law, trademark and trade dress protection for our products, which protection has been sought in many of our existing and potential future markets. Notwithstanding our efforts, there can be no assurance that our efforts to protect our trade secrets and trademarks will be successful. Nor can there be any assurance that third parties will not assert claims against us for infringement of their intellectual proprietary rights. If an infringement claim is asserted, we may be required to obtain a license of such rights, pay royalties on a retrospective or prospective basis, or terminate our manufacturing and marketing of our infringing products. Litigation with respect to such matters could result in substantial costs and diversion of management and other resources and could have a material adverse effect on our business, financial condition, or operating results. Risks Associated with Public Health Crises Pandemics, epidemics, disease outbreaks and other public health crises, such as the COVID-19 pandemic, have disrupted our business and operations, and future public health crises could materially adversely impact our business, financial condition, liquidity and results of operations. Public health crises such as pandemics, epidemics or disease outbreaks in the United States or globally, including the COVID-19 pandemic, have disrupted, and may in the future disrupt, our business, which could materially affect our results of operations, financial condition, liquidity and future expectations. Any such events may adversely impact our global supply chain and global manufacturing operations and cause us to again limit or suspend our operations in the United States, China and elsewhere. For example, to address the COVID-19 pandemic, many governments issued various restrictive orders that affected businesses and consumers. During the COVID-19 pandemic, government-imposed restrictions, health and safety mandated best practices, and public hesitance regarding in-person gatherings reduced our ability and the ability of our Associates to hold sales meetings, required our Associates to share and sell our products in a predominantly virtual environment, resulted in cancellations of key Company events and trips, required us to utilize a work-from-home strategy for all non-manufacturing and non-distribution employees, and required us to temporarily close our walk-in and fulfillment locations we maintain in some markets. The COVID-19 pandemic also affected the availability and cost of several of our raw materials, packaging materials and shipping resources to transport our product to our various markets around the world. Any new pandemic or future public health crises could have a material adverse impact on our business, financial condition, liquidity and results of operations. Risks Related to Our Common Stock The beneficial ownership of a significant percentage of our common stock gives our founder and parties related to or affiliated with him effective control, and limits the influence of other shareholders on important policy and management issues. Gull Global, Ltd., an entity that is solely owned and controlled by our founder, Dr. Myron Wentz, owned approximately 41.9% of our outstanding common stock at December 28, 2024. Dr. Wentz is no longer active in the management of USANA and is an emeritus member of our Board of Directors. By virtue of this stock ownership, Dr. Wentz is able to exert significant influence over the election of the members of our Board of Directors and our business affairs. This concentration of ownership could also have the effect of delaying, deterring, or preventing a change in control that might otherwise be beneficial to shareholders. There can be no assurance that conflicts of interest will not arise with respect to these relationships or that conflicts will be resolved in a manner favorable to our other shareholders. Sales by our shareholders of a substantial number of shares of our common stock in the public market could adversely affect the market price of our common stock. A large number of outstanding shares of our common stock are held by several of our principal shareholders, including Gull Global, Ltd. If any of these principal shareholders were to decide to sell large amounts of stock over a short period of time such sales could cause the market price of our common stock to decline. The market price of our common stock may be influenced by many factors, some of which are beyond our control. There can be no assurance that an active market in our stock will be sustained. We have a relatively small public float compared to the number of our shares outstanding. Accordingly, we cannot predict the extent to which investors’ 43

interest in our common stock will provide an active and liquid trading market. We are also vulnerable to investors taking a “short position” in our common stock, which has the effect of depressing the price of our common stock and adding volatility to our trading market. The price of our common stock also may fluctuate in the future in response to quarter-to- quarter variations in operating results, material announcements by us or our competitors, governmental regulatory action, conditions in the nutritional supplement industry, negative publicity, or other events or factors, many of which are beyond our control. In addition, the stock market has historically experienced significant price and volume fluctuations, which have particularly affected the market prices of many dietary and nutritional supplement companies and which have not had a strong correlation in certain cases to the operating performance of these companies. Our operating results in future quarters may be below the expectations of securities analysts and investors. If that were to occur, the price of our common stock, and accordingly, the value of a shareholder’s investment in our company, would likely decline, perhaps substantially. Item 1B. Unresolved Staff Comments There are no unresolved comments that were received from the SEC staff relating to our periodic or current reports under the Securities Exchange Act of 1934. Item 1C. Cybersecurity Overview. We have implemented and maintain a cybersecurity risk management program, which consists of, among other things, comprehensive processes to identify, assess, manage, and mitigate material cybersecurity threats as part of our broader enterprise risk management program. We utilize an internal team of cybersecurity professionals and data privacy professionals to oversee this program. Where appropriate, we obtain input from external experts on our program, including with respect to prevailing cybersecurity practices and the latest cyber threat trends. Cybersecurity Team. Our internal team of cybersecurity and data privacy professionals oversee, among other things, our cybersecurity risk management and mitigation, incident prevention, detection, and remediation. The leadership of these teams is comprised of various professionals with cybersecurity expertise, including our Executive Vice President of Information Security and Disaster Recovery, who reports to our Chief Operating Officer. Our Executive Vice President of Information Security and Disaster Recovery has a bachelor’s degree in computer information systems, multiple university certifications in advanced cybersecurity, and over 30 years’ experience in cybersecurity and technology roles at various companies. Our executive leadership team, with input from the above teams, is responsible for our overall enterprise risk management system and associated processes, and regularly considers cybersecurity risks in the context of other material risks to the Company. Risk Management Program Components, Training, and Incident Response. As part of our cybersecurity risk management program, our incident response team tracks and logs cybersecurity and data privacy incidents across the Company to identify, assess, mitigate, remediate, and resolve any such incidents. Prior to forming a contractual relationship with a material vendor or third-party service provider that will have access to our information systems or data, we perform due diligence on their cybersecurity and data privacy posture. We conduct annual reviews and tests of our information security program and we periodically review and update our cybersecurity policies. We also periodically utilize qualified third parties to evaluate and assess our cybersecurity risk management program, including through conducting cybersecurity maturity assessments. We utilize cybersecurity user awareness trainings with our employees, cybersecurity insurance, business continuity mechanisms, tabletop exercises, penetration testing, and vulnerability scanning to evaluate the effectiveness of our information security program and improve our security measures and planning. The material results of these assessments are reported to our executive leadership team and the Governance, Risk and Nominating Committee of the Company’s Board of Directors (the “Board”). We have adopted a cybersecurity and data privacy incident response plan that provides a framework for identifying, classifying, documenting, and responding to cybersecurity and data privacy incidents and determining whether reporting of an incident is appropriate or required under regulatory standards. The plan also includes a materiality assessment framework to assist us in determining whether a security incident is “material” under the federal securities laws. A cross-functional working group reviews significant cybersecurity incidents under this framework to assess the incident and, among other things, determine whether further assessment and escalation of the incident within USANA is appropriate. Any incident assessed as being or potentially becoming material is immediately escalated to designated members of our executive leadership team. We consult with outside cybersecurity and data privacy consultants and legal 44

counsel as appropriate, including on cyber incident significance and/or materiality analysis and disclosure matters, and designated members of our management team make the final materiality determinations and disclosure and other compliance decisions. Our management apprises the Governance Risk and Nominating Committee and, where necessary, our independent registered public accounting firm, of cybersecurity matters and relevant developments, as appropriate. Governance. Our Board is actively involved in the assessment, oversight and management of the material risks that could affect the Company. The Board carries out its risk oversight and management responsibilities by monitoring risk directly as a full Board and, where appropriate, through its committees. The Board has delegated to the Governance, Risk and Nominating Committee the ultimate oversight responsibility for risks and incidents relating to cybersecurity threats, including compliance with disclosure requirements, cooperation with law enforcement, and related effects on financial and other risks, and it reports any findings and recommendations, as appropriate, to the full Board for consideration. Our cybersecurity and data privacy professionals regularly discuss cyber risks and trends and, should they arise, any material incidents with management and the Governance, Risk and Nominating Committee. Material Risks from Cybersecurity Threats. As a global company with operations and customers in 25 markets, we encounter a variety of cybersecurity threats. However, our business strategy, results of operations and financial condition have not been materially affected by risks from cybersecurity threats. Nevertheless, we cannot provide assurance that they will not be materially affected in the future by such risks or any future material incidents. For more information on our cybersecurity related risks, see “Item 1A. Risk Factors.” of this Annual Report on Form 10-K. Item 2. Properties Corporate Headquarters Our world-wide corporate headquarters is a 354,000 square foot company-owned facility located in Salt Lake City, Utah. In addition to executive offices, this facility includes space for manufacturing and quality control, distribution, administrative functions, and research and development. This facility manufactures inventories for all global markets, excluding China. Additionally, we own a 54,000 square foot manufacturing facility, located adjacent to the corporate headquarters facility, where we began in-house manufacturing of our foods product line during the fourth quarter of 2020. China Manufacturing We own a 350,000 square foot state-of-the-art facility in Beijing, China similar in potential capacity and nature to our corporate headquarters to manufacture products sold in China. Additionally, we own a 31,000 square foot manufacturing facility in Tianjin, China, where we manufacture our skincare products for sale in China. Other Office and Distribution Warehouse Facilities We own a 45,000 square foot office and warehouse building in Sydney, Australia. In other markets, we lease regional offices and distribution warehouses. Additionally, we lease retail centers for our operations in China. We believe that the facilities referenced above are in good condition and are adequately utilized. Further, we believe that our current and planned manufacturing facilities provide for the productive capacity to meet our foreseeable needs. Item 3. Legal Proceedings We are a party to litigation and other proceedings that arise in the ordinary course of conducting business, including matters involving our products, intellectual property, supplier relationships, distributors, competitor relationships, employees and other matters. Information with respect to legal proceedings may be found in Note K to the Consolidated Financial Statements included in Part II, Item 8 of this Annual Report, which is incorporated herein by reference. 45

Item 4. Mine Safety Disclosures Not applicable. 46

PART II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Market Information Our common stock trades on the NYSE under the symbol “USNA.” As of March 7, 2025, we had approximately 230 holders of record of our common stock. We have never declared or paid cash dividends on our common stock. Future cash dividends, if any, will be determined by our Board of Directors and will be based on earnings, available capital, our financial condition, and other factors that the Board of Directors deems to be relevant. Information regarding securities authorized for issuance under equity compensation plans is included in Item 12. “Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.” Share Repurchases Our share repurchase plan has been ongoing since the fourth quarter of 2000, with our Board of Directors periodically approving additional dollar amounts for share repurchases under the plan. There were no share repurchases made during the quarter ended December 28, 2024. As of December 28, 2024, the remaining authorized repurchase amount under the stock repurchase plan was $61.7 million inclusive of accrued excise tax. There is no expiration date on the remaining approved repurchase amount and no requirement for future share repurchases. Stock Performance Graph The following graph and table compare the performance of our common stock to the Russell 2000 Index ("Index") and to a market-weighted index of six companies selected in good faith from our industry (the “Peer Group”) over the last five years. The data shown assumes an investment on December 31, 2019, of $100 in our common stock and each of the other equities and reinvestment of all dividends into additional shares of the same class of equity, if applicable to the stock or index. Each of the companies included in the Peer Group markets or manufactures products similar to our products or markets its products through a similar marketing channel.

Management’s Discussion and Analysis of Financial Condition and Results of Operations The following discussion and analysis of USANA’s financial condition and results of operations is presented in nine sections: • Overview • Customers • Presentation • Non-GAAP Financial Measures • Results of Operations • Liquidity and Capital Resources • Contractual Obligations and Commercial Contingencies • Inflation • Critical Accounting Policies and Estimates This discussion and analysis from management's perspective should be read in conjunction with the Consolidated Financial Statements and notes thereto appearing elsewhere in this report. Overview We develop and manufacture high quality, science-based nutritional and personal care and skincare products that are distributed internationally primarily through direct selling. We use this distribution method because we believe it is more conducive to meeting our vision as a company, which is to improve the overall health and nutrition of individuals and families around the world. Our customer base is primarily comprised of two types of customers: “Associates” and “Preferred Customers,” referred to together as “active Customers.” Our Associates also sell our products to retail customers. Associates share in our company vision by acting as independent distributors of our products in addition to purchasing our products for their personal use. In 2023, we launched our Affiliate program in the United States, Canada, and Mexico and are evaluating introducing the program in other markets. This program offers another sales and compensation opportunity to individuals who are interested in selling USANA products. Affiliates are discussed and reported in this report with Associates. Preferred Customers purchase our products strictly for personal use and are not permitted to resell or to distribute the products. We only count as active Customers those Associates and Preferred Customers who have purchased from us at any time during the most recent three-month period. As of December 28, 2024, we had approximately 454,000 direct selling active Customers worldwide. In addition, on December 23, 2024, we acquired a 78.85% controlling ownership interest in Hiya, a leading provider of high-quality children's health and wellness products through which we operate our direct-to-consumer business. Customers Because we primarily sell our products to a customer base of independent Associates and Preferred Customers, we increase our sales by increasing the number of our active Customers, the amount they spend on average, or both. Our primary focus continues to be increasing the number of active Customers. We believe this focus is consistent with our 48

vision of improving the overall health and nutrition of individuals and families around the world. Sales to Associates account for approximately 52% of direct selling segment product sales during 2024, with the remainder being to Preferred Customers. Increases or decreases in product sales are typically the result of variations in the volume of product sold relating to fluctuations in the number of active Customers purchasing our products. The number of active Associates and Preferred Customers is therefore used by management as a key non-financial indicator to evaluate our operational performance. The table below summarizes the change in our direct selling active Customer base by geographic region, rounded to the nearest thousand, as of the dates indicated. Total Active Customers by Region Change from Prior Year Percent Change As of December 28, 2024 As of December 30, 2023 Asia Pacific: Greater China 246,000 54.2 % 255,000 52.8 % (9,000) (3.5%) Southeast Asia Pacific 77,000 16.9 % 80,000 16.6 % (3,000) (3.8%) North Asia 38,000 8.4 % 48,000 9.9 % (10,000) (20.8%) Asia Pacific Total 361,000 79.5 % 383,000 79.3 % (22,000) (5.7%) Americas and Europe 93,000 20.5 % 100,000 20.7 % (7,000) (7.0%) 454,000 100.0 % 483,000 100.0 % (29,000) (6.0%) Presentation Product sales along with the shipping and handling fees billed to our customers are recorded as revenue net of applicable sales discounts when, or as control of, the promised product is transferred to the customer, which is at the time of delivery to the third party carrier for shipment. Payments received for unshipped products are recorded as deferred revenue and are included in the "Other current liabilities" line item in the consolidated balance sheet. Also reflected in net sales is a provision for a refund liability for sales returns, which is estimated based on our historical experience. Additionally, other types of revenue include fees, which are paid by the customer at the beginning of the service period, for access to online customer service applications and annual account renewal fees for Associates, for which control is transferred over time as services are delivered and are recognized as revenue on a straight-line basis over the term of the respective contracts. Cost of sales primarily consists of expenses related to raw materials, labor, quality assurance, and overhead costs that are all directly associated with the production and distribution of our products and sales materials, as well as duties and taxes that are associated with the import and export of our products. As international sales increase as a percentage of net sales, cost of sales are increasingly affected by additional duties, freight, and other factors, such as changes in currency exchange rates. Associate incentives expense includes all forms of commissions, and other incentives paid to our Associates. Incentives paid to Associates include bonuses earned, rewards from contests and promotions, and base commissions, which makes up the majority of our Associate incentives expense. We pay bonuses to Associates based on certain business-related criteria, total base commission earnings, and leadership level. Contests and promotions are offered as an incentive and reward to our Associates and are typically paid out only after an Associate achieves specific criteria. Base commissions are paid out on the sale of products. Associates earn their commissions based on sales volume points that are generated in their sales organization. Sales volume points are assigned to each commissionable product and comprise a certain percent of the product price. Items such as our starter kits and sales tools have no sales volume point value, and commissions are not paid on the sale of these items. Although insignificant to our financial statements, an Associate may earn commissions on sales volume points that are generated from personal purchases that are not considered part of their “Qualifying Sales.” To be eligible to earn commissions, an Associate must reach a certain level of Qualifying Sales each month, which may include product that they use personally or that they resell to consumers. Associates do not earn commissions on their Qualifying Sales. Commissions paid to Associates on personal purchases are considered a sales discount and are reported as a reduction to our net sales. Selling, general and administrative expenses include wages and benefits, depreciation and amortization, lease costs and utilities, Associate event costs, advertising, professional fees, marketing, and research and development expenses. Wages and benefits represent the largest component of selling, general and administrative expenses. Significant 49

depreciation and amortization expense is incurred as a result of investments in physical facilities, computer and information technology infrastructure to support our international operations. Sales to customers outside the United States are transacted in the respective local currencies and translated to U.S. dollars at weighted-average currency exchange rates for each monthly accounting period to which they relate. With the exception of China, our raw material purchases from suppliers and product purchases from third-party manufacturers are transacted in U.S. dollars. Consequently, our net sales and earnings are affected by changes in currency exchange rates. In general, our operating results are affected positively by a weakening U.S. dollar and negatively by a strengthening U.S. dollar. In our net sales discussions that follow, we approximate the impact of currency fluctuations on net sales by translating current year net sales at the average exchange rates in effect during the comparable prior-year periods. Non-GAAP Financial Measures We believe that presentation of certain non-GAAP financial information is meaningful and useful in understanding the activities and business metrics of our operations. Management believes these measures reflect an additional way of viewing aspects of our business that, when viewed with our U.S. GAAP results, provide a more complete understanding of factors and trends affecting our business. This non-GAAP financial information may be determined or calculated differently by other companies, limiting the usefulness of those measures for comparative purposes. We provide such non-GAAP financial information for informational purposes only. Readers should consider the information in addition but not instead of or superior to, our Consolidated Financial Statements prepared in accordance with U.S. GAAP, accompanying this report. In analyzing business trends and performance, management uses “constant currency” net sales, “local currency” net sales, and other currency-related financial information terms to discuss our financial results in a way we believe is helpful in understanding the impact of fluctuations in foreign-currency exchange rates and facilitating period-to-period comparisons of results of operations and providing investors an additional perspective on trends and underlying business results. Changes in our reported revenue and profits in this report include the impacts of changes in foreign currency exchange rates. As additional information to the reader, we provide constant currency assessments in the tables and the narrative information in this MD&A to remove or quantify the impact of the fluctuation in foreign exchange rates and utilize constant currency results in our analysis of performance. Our constant currency financial results are calculated by translating the current period’s financial results at the same average exchange rates in effect during the applicable prior- year period and then comparing this amount to the prior-year period’s financial results. Results of Operations Summary of 2024 Financial Results Our discussion and analysis is focused on our 2024 and 2023 financial results, including comparisons of our year- over-year performance between these years. Discussion and analysis of our 2022 fiscal year specifically, as well as the year-over-year comparison of our 2023 financial performance to 2022, are located in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 30, 2023, filed with the SEC on February 27, 2024, which is available on our investor relations website at https://ir.usana.com or the SEC’s website at www.sec.gov. That information is incorporated by reference into this report. Net sales in 2024 decreased 7.2%, or $66.5 million, to $854.5 million, compared with 2023. The decrease in net sales was primarily the result of a decrease in average spend per Customer and a decrease in active Customers, due to a challenging economic environment in many of our key markets, which had varying degrees of impact on attracting new customers. We experienced a decline in active Customers of 6.0% compared to the prior year. Additionally, unfavorable changes in currency exchange rates decreased net sales for the year by an estimated $13.6 million. Net earnings attributable to USANA decreased 34.1% to $42.0 million in 2024, when compared with 2023. The decrease in net earnings attributable to USANA was primarily the result of decreased sales, higher relative operating expenses, and a higher effective tax rate. 50

Fiscal Year 2024 compared to Fiscal Year 2023 Net Sales The following table summarizes the changes in our net sales by geographic region for the fiscal years ended December 28, 2024, and December 30, 2023: Net Sales by Region (in thousands) Change from prior year Percent change Currency impact on sales Percent change excluding currency impact Twelve Months Ended December 28, 2024 December 30, 2023 Asia Pacific Greater China $ 457,976 53.6 % $ 475,099 51.6 % $ (17,123) (3.6) % $ (7,263) (2.1) % Southeast Asia Pacific 146,795 17.2 % 163,890 17.8 % (17,095) (10.4) % (1,593) (9.5) % North Asia 78,214 9.1 % 101,446 11.0 % (23,232) (22.9) % (3,461) (19.5) % Asia Pacific Total 682,985 79.9 % 740,435 80.4 % (57,450) (7.8) % (12,317) (6.1) % Americas and Europe 171,518 20.1 % 180,575 19.6 % (9,057) (5.0) % (1,247) (4.3) % $ 854,503 100.0 % $ 921,010 100.0 % $ (66,507) (7.2) % $ (13,564) (5.7) % Asia Pacific: The decrease in constant currency net sales in Greater China was primarily the result of a sales decline in China and Taiwan where local currency net sales decreased 1.7% and 3.9%, respectively. There were local currency declines in most markets in the Southeast Asia Pacific sub-region, most notable in the Philippines, Malaysia, and Singapore, which had local currency net sales declines of 18.6%, 9.4%, and 14.0%, respectively. The decrease in constant currency net sales in North Asia was most notable in South Korea, which had a local currency net sales decline of 19.5%. Americas and Europe: There were local currency sales declines in all markets in this region. The decrease in constant currency net sales is largely the result of sales declines in the United States and Canada, which had local currency net sales declines of 7.8%, and 6.0%, respectively. Gross Profit Gross profit increased 30 basis points to 81.1% of net sales, up from 80.8% in 2023. The increase in gross profit margin can be attributed to favorable changes in market and product sales mix, lower inventory scrap, the impact of modest price increases that occurred throughout the year, and lower material costs in China. These increases were partially offset by unfavorable changes in currency exchange rates. Associate Incentives Associate incentives decreased 20 basis points to 42.6% of net sales in 2024, compared with 42.8% in the prior year. The relative decrease can primarily be attributed to benefits from modest price increases that occurred throughout the year, was well as decreased spend on Associate incentive promotions. These improvements were partially offset by an unfavorable shift in market sales mix and higher spending on distributor trips and events. Selling, General and Administrative Expenses Selling, general and administrative expenses increased 280 basis points relative to net sales and increased $6.3 million in absolute terms. The relative increase can be attributed to leverage lost on lower net sales. The increased expense in absolute terms can be primarily attributed to an increase in spending for legal and other professional services, which can be attributed to acquisition related costs of $8.2 million. This increase was partially offset by a decrease in spending for employee related costs. 51

Income Taxes Income taxes increased to 44.9% of pre-tax earnings in 2024, up from 37.7% of pre-tax earnings in 2023. The higher effective tax rate is primarily attributable to the distribution of pre-tax earnings between markets. This increase was offset, in part, by a change in U.S. tax law for foreign currency conversion of foreign branch operations. Diluted Earnings Per Share Attributable to USANA Diluted earnings per share attributable to USANA decreased to $2.19 in 2024 from $3.30 in 2023. This decrease can be attributed to lower net earnings. Liquidity and Capital Resources We have historically met our working capital and capital expenditure requirements by using net cash flow from operations and by drawing on our line of credit. Our principal source of liquidity is our operating cash flow. Although we are required to maintain cash deposits with banks in certain of our markets, there are currently no material restrictions on our ability to transfer and remit funds among our international markets. In China, however, our compliance with Chinese accounting and tax regulations promulgated by the State Administration of Foreign Exchange (“SAFE”) results in transfer and remittance of our profits and dividends from China to the United States on a delayed basis. If SAFE or other Chinese regulators introduce new regulations or change existing regulations which allow foreign investors to remit profits and dividends earned in China to other countries, our ability to remit profits or pay dividends from China to the United States may be limited in the future. We believe our current liquidity, through cash flow from operations, is adequate to meet our cash requirements and sustain our operations. Maintaining a capital structure that emphasizes sufficient liquidity and adaptability in the prevailing economic climate is our top priority. We actively assess potential acquisition opportunities and investments in complementary ventures. While we continuously aim to preserve ample liquidity and ensure business continuity amid uncertainties, we also explore initiatives such as stock repurchases. These strategic decisions have the potential to impact our liquidity, enabling us to navigate these challenging times effectively. Cash and Cash Equivalents Cash and cash equivalents decreased to $181.8 million at December 28, 2024, from $330.4 million at December 30, 2023. Cash flow provided by operating and financing activities was $61.0 million and $9.6 million, respectively, offset by cash used in investing activities of $213.1 million. Additionally, unfavorable changes in currency exchange rates, have impacted cash and cash equivalents, and restricted cash by an estimated $6.2 million. The following table below presents concentrations of cash and cash equivalents by market for the periods indicated: Cash and cash equivalents (in millions) As of December 28, 2024 As of December 30, 2023 United States $ 40.1 $ 169.9 China 101.2 111.0 All other markets 40.5 49.5 Total Cash and cash equivalents $ 181.8 $ 330.4 Cash Flows Provided by Operations and Significant Uses of Cash As discussed above, our principal source of liquidity comes from cash flows from operations. Net cash flow provided by operating activities totaled $61.0 million in 2024. Net earnings combined with adjustments of non-cash items contributed positively to our net cash flow provided by operating activities, partially offset by changes in working capital. Other significant uses of cash included the Hiya Acquisition of $203.3 million, net of cash acquired, and an investment of $10.1 million to purchase property and equipment. Additionally, cash used to repurchase and retire shares totaled $9.4 million in 2024. 52

Net cash flow provided by operating activities totaled $70.6 million in 2023. Net earnings combined with adjustments of non-cash items contributed positively to our net cash flow provided by operating activities, partially offset by $14.5 million in cash used to purchase property and equipment primarily related to our digital commerce initiatives and our India operations and cash used to repurchase and retire shares of $11.6 million. Line of Credit Information with respect to our line of credit may be found in Note J to the Consolidated Financial Statements included in Part II, Item 8 of this Annual Report, which is incorporated by reference. Share Repurchase Information with respect to our share repurchases may be found in Note N to the Consolidated Financial Statements included in Part II, Item 8 of this Annual Report, which is incorporated by reference. Off-Balance Sheet Arrangements None. Summary We believe our current cash balances, future cash provided by operations, and amounts available under our line of credit will be sufficient to cover our operating and capital needs in the ordinary course of business for the foreseeable future. If we experience an adverse operating environment or unanticipated and unusual capital expenditure requirements, additional financing may be required. No assurance can be given, however, that additional financing, if required, would be available to us at all or on favorable terms. We might also require or seek additional financing for the purpose of expanding into new markets, growing our existing markets, mergers and acquisitions, or for other reasons. Such financing may include the use of debt or the sale of additional equity securities. Any financing which involves the sale of equity securities or instruments that are convertible into equity securities could result in immediate and possibly significant dilution to our existing shareholders. Contractual Obligations and Commercial Contingencies The following table summarizes our contractual obligations and commitments as of December 28, 2024, and the effect such obligations and commitments are expected to have on our liquidity and cash flow in future periods: Payments Due By Period (in thousands) Contractual Obligations Total Less than 1 year 1 - 3 years 3 - 5 years More than 5 years Operating Leases $ 17,824 $ 6,742 $ 6,982 $ 4,074 $ 26 Other Commitments 31,363 20,493 9,675 1,166 29 Total Contractual Obligations $ 49,187 $ 27,235 $ 16,657 $ 5,240 $ 55 “Operating Leases” generally provide that property taxes, insurance, and maintenance expenses are our responsibility. Such expenses are not included in the operating lease amounts in the table above. Information with respect to our Operating Leases may be found in Note G to the Consolidated Financial Statements included in Part II, Item 8 of this Annual Report, which is incorporated by reference. “Other Commitments” generally include consulting- and IT-related services, investments in brand awareness through corporate and athlete sponsorships, facility maintenance, services related to the events that we hold for our Associates both locally and internationally, and local lines of credit. Additionally, throughout the year we will enter into various short-term contracts, mostly for services related to events that we hold for our Associates. Information with respect to our unconditional purchase obligations may be found in Note K to the Consolidated Financial Statements included in Part II, Item 8 of this Annual Report, which is incorporated by reference. 53

Inflation Like many other global companies, we are facing significant inflationary pressures in the world economy. Inflationary pressures are growing as we renew pricing arrangements, notably for certain direct materials, wages, energy, and transportation costs. These inflationary pressures, including margin pressure from inflation as well as the cost of capital could continue to grow in 2025. Critical Accounting Policies and Estimates Our Consolidated Financial Statements included in this report have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Our significant accounting policies are described in the Consolidated Financial Statements included herein. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Those estimates and assumptions are derived and are continually evaluated based on our historical experiences, current facts and circumstances, and on changes in the business environment. Actual results, however, may sometimes differ materially from estimates under different conditions. Critical accounting estimates are defined as both those that are material to the portrayal of our financial condition and results of operations and those that require management’s most subjective judgments. We believe that our most critical accounting policies and estimates are described in this section. Revenue Recognition. Revenue is recognized when, or as, control of a promised product or service transfers to a customer, in an amount that reflects the consideration to which we expect to be entitled in exchange for transferring those products or services. Revenue recognition is evaluated through the following five-step process: 1) identification of the contract with a customer; 2) identification of the performance obligations in the contract; 3) determination of the transaction price; 4) allocation of the transaction price to the performance obligations in the contract; and 5) recognition of revenue when or as a performance obligation is satisfied. A majority of our sales are for products sold at a point in time and shipped to customers, for which control is transferred to the customer as goods are delivered to the third-party carrier for shipment. We receive payment, primarily via credit card, for the sale of products at the time customers place orders and payment is required prior to shipment. Our product sales contracts include terms that could cause variability in the transaction price for items such as discounts, credits, or sales returns. Accordingly, the transaction price for product sales includes estimates of variable consideration to the extent it is probable that a significant reversal of revenue recognized will not occur. At the time of sale, we estimate a refund liability for the variable consideration based on historical experience. Initial product orders with a new customer may include multiple performance obligations related to sales discounts earned under our initial order reward program. Under this program, the customer receives an option to apply the discounts earned on the initial order to two subsequent Auto Orders, which conveys a material right to the customer. As such, the initial order transaction price is allocated to each separate performance obligation based on its relative standalone selling price and recognized as revenue as each performance obligation is satisfied. Associate incentives represent consideration paid and include all forms of commissions, and other incentives paid to our Associates. With the exception of commissions paid to Associates on personal purchases, which are considered a sales discount and are reported as a reduction to net sales, the incentives are paid for distinct services related to our product sales and are recorded as an expense when revenue for the goods is recognized. Shipping and handling activities are performed upon delivery to the third-party carrier for shipment. We account for these activities as fulfillment costs. Therefore, we recognize the costs of these activities when revenue for the goods is recognized. Shipping and handling costs are included in cost of sales for all periods presented. Contract liabilities relate to deferred revenue for product sales for customer payments received in advance of shipment, for outstanding material rights under the initial order program, and for services where the performance obligations are satisfied over time as services are delivered. Contract liabilities are recorded as deferred revenue within the “Other current liabilities” line item in the consolidated balance sheet. Deferred revenue is recognized when or as the related performance obligation is satisfied. On the occasion that will-call orders are not picked up by customers, we periodically assess the likelihood that customers will exercise their contractual right to pick up orders and recognize revenue when the likelihood that customers will pick up orders becomes remote. 54

Business Combinations. To record the value of assets acquired, liabilities assumed, and noncontrolling interest as a result of our acquisition of Hiya on December 23, 2024, we have performed a purchase price allocation utilizing the best information available to management. Assets acquired, liabilities assumed, and noncontrolling interests as part of a business acquisition are generally recorded at their fair value at the date of acquisition. The excess of purchase price over the fair value of assets acquired, liabilities assumed, and noncontrolling interest is recorded as goodwill. The acquisition method requires management to make assumptions and apply judgment, particularly for those assets acquired, liabilities assumed, and noncontrolling interest for which inputs are unobservable, such as trade name and customer relationship intangible assets. The fair value for the acquired trade name intangible asset was estimated utilizing an income approach, specifically the multi-period excess earnings method. The fair value for the acquired customer relationship intangible asset was estimated utilizing an income approach, specifically the with-and-without method. Both methods involve the use of significant estimates and assumptions including related to projected revenue growth rates, projected earnings before interest, taxes, depreciation and amortization (“EBITDA”) margins, and discount rates. Intangible assets estimated and recognized as a result of the Hiya Acquisition are based upon assumptions and inputs which have inherent estimation uncertainty. These estimates may be adjusted as more current information becomes available, and any adjustment could be material. Item 7A. Quantitative and Qualitative Disclosures About Market Risk Our earnings, cash flows, and financial position are affected by fluctuations in currency exchange rates, interest rates, and other uncertainties that are inherent in doing business and selling product in more than one currency. In addition, our operations are exposed to risks that are associated with changes in social, political, and economic conditions in our international operations. This includes changes in the laws and policies that govern investment in international countries where we have operations, as well as, to a lesser extent, changes in U.S. laws and regulations relating to international trade and investment. Foreign Currency Risks. Because a significant portion of our sales are generated outside the United States, currency exchange rate fluctuations may have a significant effect on our sales and earnings. The local currency of each international subsidiary is considered the functional currency, with all revenue and expenses being translated at weighted- average currency exchange rates for the applicable periods. In general, our reported sales and gross profit are affected positively by a weakening of the U.S. dollar and negatively by a strengthening of the U.S. dollar because we manufacture the majority of our products in the United States and sell them to our international subsidiaries in their respective functional currencies. Currency fluctuations, however, have the opposite effect on our Associate incentives and selling, general and administrative expenses. We are unable to reasonably estimate the effect that currency fluctuations may have on our future business, results of operations, or financial condition. This is due to the uncertainty in, and the varying degrees and type of exposure that we face from, fluctuation of various currencies. Currently our strategy for reducing our exposure to currency fluctuation includes the timely and efficient repatriation of earnings from international markets, and settlement of intercompany transactions. Additionally, we may enter into short-term foreign currency credit arrangements in our international markets, primarily as a way to reduce our exposure to negative effects of changes in foreign currency exchange rates. We also enter into currency exchange contracts to offset foreign currency exposure in various international markets. We do not use derivative financial instruments for trading or speculative purposes. There can be no assurance that our practices will be successful in eliminating all or substantially all of the risks that we may encounter in connection with our currency transactions. Interest Rate Risks. As of December 28, 2024, we had $23 million of outstanding debt on our credit facility. Based on this limited activity our exposure to interest rate risk is immaterial. It may become necessary to borrow more in the future in order to meet our financing needs. In the event that it becomes necessary to borrow, there can be no assurance that we will be able to borrow, or at favorable rates. Item 8. Financial Statements and Supplementary Data The Financial Statements and Supplementary Data required by this Item are set forth at the pages indicated at Part IV, Item 15, below, and are incorporated into this Item 8 by reference. Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure Not applicable. 55

Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures We maintain disclosure controls and procedures that are designed to ensure that information that is required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods that are specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including our Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), as appropriate, to allow timely decisions regarding any required disclosure. In designing and evaluating these disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. As of the end of the period covered by this report, our Chief Executive Officer and Chief Financial Officer evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective to provide reasonable assurance as of December 28, 2024. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). The Company’s internal control over financial reporting is a process designed by, or under the supervision of, the Company's Chief Executive Officer and Chief Financial Officer and effected by the Company's Board of Directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements for external purposes in accordance with U.S. GAAP and includes those policies and procedures that: • Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; • Provide reasonable assurance that transactions are recorded as necessary to permit preparation of the consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and • Provide reasonable assurance regarding the prevention or timely detection of any unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the consolidated financial statements. Internal control over financial reporting has inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements will not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. Our management, including our Chief Executive Officer and our Chief Financial Officer, under the oversight of our Board of Directors, assessed the effectiveness of our internal control over financial reporting as of December 28, 2024. In making this assessment, management used the criteria that have been set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (2013). Management's assessment excluded internal control over financial reporting related to Hiya, acquired December 23, 2024. Hiya's total assets represented approximately 36% of the Company’s consolidated assets, and net sales represented approximately 0.2% of the Company’s consolidated net sales as of and for the year ended December 28, 2024. Based on its assessment, using those criteria, management concluded that, as of December 28, 2024, our internal control over financial reporting was effective. The effectiveness of the Company’s internal control over financial reporting, as of December 28, 2024, has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report which appears herein. Remediation Efforts to Address Material Weaknesses As disclosed in Part II Item 9A Controls and Procedures in our Annual Report on Form 10-K for the fiscal year ended December 30, 2023, we identified material weaknesses in internal control over financial reporting associated with information technology general controls (“ITGCs”). During 2024, we implemented controls to address our previously disclosed remediation plan which included: 56

• Enhancing our IT organization that is responsible for the development, monitoring, and testing of the ITGCs to ensure sufficiency of resources with the appropriate knowledge, experience, and training; and • Developing a training program addressing ITGCs and related policies, to educate control owners on the principles and requirements of internal control activities, including maintaining adequate evidence of the controls’ operation and ensuring timely and consistent performance of the controls as designed. During the fourth quarter of 2024, we completed our testing of the operating effectiveness of the implemented controls and found them to be effective. As a result, we have concluded that the material weaknesses were remediated as of December 28, 2024. Changes in Internal Control over Financial Reporting On December 23, 2024, the Company acquired Hiya. As permitted by Securities and Exchange Commission staff interpretive guidance for newly acquired businesses, management excluded Hiya from its annual evaluation of internal control over financial reporting as of December 28, 2024. We have begun the process of assessing Hiya’s internal controls over financial reporting and plan to incorporate Hiya in our evaluation of internal controls over financial reporting in 2025. With the exception of remediation efforts described above, there were no changes in our internal control over financial reporting during the fiscal quarter ended December 28, 2024, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 57

Report of Independent Registered Public Accounting Firm To the Stockholders and Board of Directors USANA Health Sciences, Inc.: Opinion on Internal Control Over Financial Reporting We have audited USANA Health Sciences, Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 28, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 28, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 28, 2024 and December 30, 2023, the related consolidated statements of comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 28, 2024, and the related notes and financial statement schedule II - valuation and qualifying accounts (collectively, the consolidated financial statements), and our report dated March 12, 2025 expressed an unqualified opinion on those consolidated financial statements. The Company acquired Hiya Health Products, LLC during 2024, and management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 28, 2024, Hiya Health Products, LLC’s internal control over financial reporting associated with approximately 36% of the Company’s consolidated assets and 0.2% of the Company’s consolidated net sales included in the consolidated financial statements of the Company as of and for the year ended December 28, 2024. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of Hiya Health Products, LLC. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 58

Report of Independent Registered Public Accounting Firm To the Stockholders and Board of Directors USANA Health Sciences, Inc.: Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated balance sheets of USANA Health Sciences, Inc. and subsidiaries (the Company) as of December 28, 2024 and December 30, 2023, the related consolidated statements of comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 28, 2024, and the related notes and financial statement schedule II - valuation and qualifying accounts (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 28, 2024 and December 30, 2023, and the results of its operations and its cash flows for each of the years in the three-year period ended December 28, 2024, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 28, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 12, 2025 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Fair value of trade name and customer relationship intangible assets acquired in a business combination As discussed in Note B to the consolidated financial statements, on December 23, 2024, the Company consummated its acquisition of Hiya Health Products, LLC (Hiya) for a total purchase price of $206,161. In connection with the business combination, the Company recorded various intangible assets, which included trade name and customer relationship intangible assets with acquisition date fair values of $69,500 and $54,700, respectively. The Company estimated the fair values of the intangible assets using income-based approaches including the multi-period excess earnings method for the trade name and the with-and-without method for the customer relationship. We identified the evaluation of the fair values of the trade name and customer relationship intangible assets acquired in the Hiya business combination as a critical audit matter. Subjective auditor judgment was required to evaluate certain assumptions used in the valuation of the trade name and customer relationship intangible assets, specifically the projected revenue growth rates, projected earnings before interest, taxes, depreciation and amortization (EBITDA) F-1

margins, and discount rates. Additionally, evaluating the discount rates required specialized skills and knowledge. Minor changes in these assumptions could have had a significant impact on the Company’s estimate of the fair value of the trade name and customer relationship intangible assets. The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s acquisition date valuation process, including controls related to the development of the projected revenue growth rates, projected EBITDA margins, and discount rates. We evaluated the projected revenue growth rates and projected EBITDA margins by comparing them to the historical financial results of the acquired business and peer company external market information. We involved valuation professionals with specialized skills and knowledge, who assisted in evaluating the Company’s discount rates by independently developing a range of discount rates based on publicly available market data for comparable entities and comparing them to the Company’s discount rates. /s/ KPMG LLP We have served as the Company’s auditor since 2013.

NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company USANA Health Sciences, Inc. and subsidiaries ("the Company") is a global nutrition, personal health and wellness company that develops and manufactures high quality, science-based nutritional and personal care products. For financial reporting purposes, we categorize our operations into two reportable segments: Direct selling and Hiya direct-to-consumer, with the remaining operating segments that are not material included as a component of an other category. On December 23, 2024, the Company entered into a merger agreement with Hiya Health Products, LLC ("Hiya"), a leading direct-to-consumer provider of high-quality children's health and wellness products, by which the Company acquired a 78.85% controlling ownership interest. Refer to Note B - Business Combinations for further discussion. The Company's direct selling operations are grouped and presented in two geographic regions: (1) Asia Pacific and (2) Americas and Europe. Asia Pacific is further divided into three sub-regions: (i) Greater China, (ii) Southeast Asia Pacific, and (iii) North Asia. Asia Pacific (1) Asia Pacific is organized into three sub-regions: Greater China, Southeast Asia Pacific, and North Asia. Markets included in each of these sub-regions are as follows: (i) Greater China - Hong Kong, Taiwan, and China. Our business in China is conducted by BabyCare (ii) Southeast Asia Pacific – Australia, New Zealand, Singapore, Malaysia, the Philippines, Thailand, Indonesia, and India(1) (iii) North Asia – Japan and South Korea Americas and Europe (2) Americas and Europe – United States, Canada, Mexico, Colombia, and Europe (the United Kingdom, France, Germany, Spain, Italy, Romania, Belgium, and the Netherlands) (1) We commenced operations in this market near the end of the fourth quarter of 2023. Principles of Consolidation and Basis of Presentation The accompanying Consolidated Financial Statements (the "Financial Statements") include the accounts and operations of the Company as well as amounts related to the redeemable noncontrolling interest. Refer to Note O - Redeemable Noncontrolling Interest for further detail concerning the accounting policies regarding the redeemable noncontrolling interest. The Company consolidates entities where it has a controlling financial interest. All inter-company accounts and transactions have been eliminated in consolidation. The accounting and reporting policies of the Company conform with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Intangible assets estimated and recognized as a result of the Company's acquisition of a 78.85% ownership interest in Hiya (the "Hiya Acquisition") are based upon assumptions and inputs which have inherent estimation uncertainty. These estimates may be adjusted as more current information becomes available, and any adjustment could be significant. USANA HEALTH SCIENCES, INC.

Fiscal Year The Company operates on a 52/53-week year, ending on the Saturday closest to December 31. Fiscal years 2024, 2023, and 2022 were 52-week years. Fiscal year 2024 covered the period December 31, 2023 to December 28, 2024 (hereinafter 2024). Fiscal year 2023 covered the period January 1, 2023 to December 30, 2023 (hereinafter 2023). Fiscal year 2022 covered the period January 2, 2022 to December 31, 2022 (hereinafter 2022). Fair Value Measurements The Company measures at fair value certain of its financial and non-financial assets and liabilities by using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability. The levels of the fair value hierarchy are: • Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date. • Level 2 inputs are from other than quoted market prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. • Level 3 inputs are unobservable and are used to measure fair value in situations where there is little, if any, market activity for the asset or liability at the measurement date. As of December 28, 2024 and December 30, 2023, the following financial assets and liabilities were measured at fair value on a recurring basis using the type of inputs shown: December 28, 2024 Fair Value Measurements Using Inputs Level 1 Level 2 Level 3 Money market funds included in cash equivalents $ 116,071 $ 116,071 $ — $ — Foreign currency contracts included in other current liabilities (43) — (43) — Deferred compensation liabilities (4,684) — (4,684) — December 30, 2023 Fair Value Measurements Using Inputs Level 1 Level 2 Level 3 Money market funds included in cash equivalents $ 258,319 $ 258,319 $ — $ — Foreign currency contracts included in other current liabilities (62) — (62) — Deferred compensation liabilities (3,137) — (3,137) — There were no transfers of financial assets or liabilities between levels of the fair value hierarchy for the periods indicated. The majority of the Company’s non-financial assets, which include long-lived assets, are not required to be carried at fair value on a recurring basis. However, if an impairment charge is required, a non-financial asset would be written down to fair value. As of December 28, 2024 and December 30, 2023, none of the Company's non-financial assets were measured at fair value. Acquired assets, liabilities assumed, and redeemable noncontrolling interest of Hiya were measured at fair value at the date of acquisition. Refer to Note B, "Business Combinations".

Fair Value of Financial Instruments As of December 28, 2024 and December 30, 2023, the Company’s financial instruments include cash equivalents, restricted cash, and line of credit. The recorded values of each approximate their fair values, based on their short-term nature. Translation of Foreign Currencies The functional currency of the Company’s foreign subsidiaries is the local currency of their country of domicile. Assets and liabilities of the foreign subsidiaries are translated into U.S. dollar amounts at month-end exchange rates. Revenue and expense accounts are translated at the weighted-average rates for the monthly accounting period to which they relate. Equity accounts are translated at historical rates. Foreign currency translation adjustments are accumulated as a component of other comprehensive income. Gains and losses from foreign currency transactions are included in the “Other, net” component of Other income (expense) in the Company’s consolidated statements of comprehensive income. Business Combinations The Company allocates the purchase price consideration of the assets acquired, liabilities assumed, and noncontrolling interest in the acquiree based on the acquisition date fair values. Additionally, the Company records goodwill for the excess of the total consideration given for the acquired business over the fair value of the identifiable net assets of the acquired business. Transaction costs attributable to the acquisition are expensed as incurred. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less from the date of purchase to be cash equivalents. Cash equivalents as of December 28, 2024 and December 30, 2023 consisted primarily of money market fund investments and amounts receivable from credit card processors. Amounts receivable from credit card processors and other forms of electronic payment are considered cash equivalents because they are both short-term and highly liquid in nature and are typically converted to cash within three days of the sales transaction. Amounts receivable from credit card processors as of December 28, 2024 and December 30, 2023 totaled $9,122 and $9,379, respectively. Restricted Cash The Company is required to maintain cash deposits with banks in certain subsidiary locations for various operating purposes. The most significant of these cash deposits relates to a deposit held at a bank in China, the balance of which was $2,740 as of December 28, 2024, and $2,826 as of December 30, 2023. This deposit is required for the application of direct selling licenses by the Ministry of Commerce and the State Administration of Market Regulation (“SAMR”) of the People’s Republic of China, and will continue to be restricted during the periods while the Company holds these licenses. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using a standard costing system, which approximates the first-in, first-out method. The components of inventory cost include raw materials, labor, and overhead. Net realizable value is determined using various assumptions with regard to excess or slow-moving inventories, non-conforming inventories, expiration dates, current and future product demand, production planning, and market conditions. A change in any of these variables could result in an adjustment to inventory. Noncurrent inventories are inventories not expected to be sold within the normal operating cycle. The Company has defined the operating cycle as 52-weeks. Noncurrent inventories are classified in the "Other assets" line item in the Company's consolidated balance sheets. Noncurrent inventories are anticipated to be consumed beyond our normal operating cycle, but prior to obsolescence. USANA HEALTH SCIENCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share data) NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED F-10

Accounts Receivable Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for credit losses for expected credit losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and our customers’ financial condition, the amount of receivables in dispute, and the current receivables aging and current payment patterns. The Company reviews its allowance for credit losses regularly. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Accounts receivable is included in the “Prepaid expenses and other current assets” line item in the Company’s consolidated balance sheets. Income Taxes The Company accounts for income taxes using the asset and liability method, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of the differences between the financial statement assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that are expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax law is recognized in income in the period that includes the enactment date. Deferred tax expense or benefit is the result of changes in deferred tax assets and liabilities. The Company evaluates the probability of realizing the future benefits of its deferred tax assets and provides a valuation allowance for the portion of any deferred tax assets where the likelihood of realizing an income tax benefit in the future does not meet the “more-likely-than-not” criteria for recognition. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the Financial Statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. The Company recognizes interest and penalties related to unrecognized tax benefits in income taxes. Property and Equipment Property and equipment are recorded at cost. Maintenance, repairs, and renewals, which neither materially add to the value of the property nor appreciably prolong its life, are charged to expense as incurred. Depreciation is provided in amounts sufficient to relate the cost of depreciable assets to operations over the estimated useful lives of the related assets. The straight-line method of depreciation and amortization is followed for financial statement purposes. Leasehold improvements are amortized over the shorter of the life of the respective lease or the useful life of the improvements. Property and equipment are reviewed for impairment whenever events or changes in circumstances exist that indicate the carrying amount of an asset may not be recoverable. When property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations for the respective period. The Company capitalizes certain internal-use software development costs, consisting primarily of employee salaries and contractor costs, during the application development stage. Costs incurred for upgrades and enhancements that are expected to result in additional functionalities are also capitalized. These development costs are amortized using the straight-line method over an estimated useful life of three to five years, and are reflected as part of Property and equipment, net on our consolidated balance sheets. Leases With the exception of the Company’s headquarters in Salt Lake City, Utah, and its facilities in New South Wales, Australia, and in Beijing and Tianjin, China, the Company leases its facilities. Each of the facility lease agreements is a non-cancelable operating lease generally structured with renewal options and expires prior to or during 2030. In connection with the production facilities in Beijing and Tianjin, China, the Company has prepaid land use rights, which represents a lease with the associated prepayment recorded as a Right-of-Use (“ROU”) asset. The Company also utilizes equipment under non-cancelable operating leases, expiring through 2026. USANA HEALTH SCIENCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share data) NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED F-11

At contract inception, the Company determines whether an arrangement is or contains a lease and whether the lease should be classified as an operating or a financing lease. A contract is or contains a lease if the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. Control is determined based on the right to obtain all of the economic benefits from use of the identified asset and the right to direct the use of the identified asset. ROU assets for operating leases represent the right to use an underlying asset for the lease term, and operating lease liabilities represent the obligation to make lease payments. Lease liabilities are recognized based on the present value of the unpaid lease payments over the lease term at the commencement date for leases exceeding 12 months. Unpaid lease payments include only the fixed lease component of the agreement, as well as any variable rate payments that depend on an index, initially measured using the index at the lease commencement date. Non-lease components are accounted for separately from the fixed lease component for all leases. Most of the Company’s leases do not provide an implicit rate that can readily be determined. Therefore, the applied discount rate is based on the Company’s incremental borrowing rate, which is determined using its credit rating and other information available as of the commencement date and is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. Lease terms may include options to renew, which the Company factors into the determination of the lease term when it is reasonably certain that the Company will exercise that option. The ROU asset is measured at the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. Operating lease expense is recognized on a straight-line basis over the lease term and is included in “Cost of sales” and “Selling, general and administrative” line items in the Company’s consolidated statements of comprehensive income. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and the expense for these short-term leases is recognized on a straight-line basis over the lease term. The Company monitors for events or changes in circumstances that require a reassessment of its leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the ROU asset unless doing so would reduce the ROU asset to an amount less than zero, in which case the remaining adjustment would be recorded in the consolidated statements of comprehensive income. Goodwill Goodwill represents the excess of the purchase price over the fair market value of identifiable net assets and noncontrolling interest of acquired companies. Goodwill is not amortized, but rather is tested at the reporting unit level at least annually for impairment or more frequently if triggering events or changes in circumstances indicate impairment. Initially, qualitative factors are considered to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Some of these qualitative factors may include macroeconomic conditions, industry and market considerations, a change in financial performance, entity-specific events, a sustained decrease in share price, and consideration of the difference between the fair value and carrying amount of a reporting unit as determined in the most recent quantitative assessment. If, through this qualitative assessment, the conclusion is made that it is more likely than not that a reporting unit’s fair value is less than its carrying amount, a quantitative impairment analysis is performed. This analysis involves estimating the fair value of a reporting unit using widely accepted valuation methodologies including the income and market approaches, which requires the use of estimates and assumptions. These estimates and assumptions include revenue growth rates, discount rates, and determination of appropriate comparable entities. If the fair value of the reporting unit is less than its carrying amount, an impairment loss is recognized in an amount equal to the excess of the carrying amount over the fair value of the reporting unit, not to exceed the carrying amount of the goodwill. During 2024, 2023, and 2022, no impairment of goodwill was recorded. Intangible Assets Intangible assets represent amortized and indefinite-lived intangible assets primarily acquired in connection with business combinations. Amortized intangible assets are amortized over their related useful lives, using a straight-line or accelerated method consistent with the underlying expected future cash flows related to the specific intangible asset. Amortized intangible assets are reviewed for impairment whenever events or changes in circumstances exist that indicate the carrying amount of an asset may not be recoverable. When indicators of impairment exist, an estimate of undiscounted net cash flows is used in measuring whether the carrying amount of the asset or related asset group is recoverable. USANA HEALTH SCIENCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share data) NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED F-12

Measurement of the amount of impairment, if any, is based upon the difference between the asset or asset group’s carrying value and fair value. Fair value is determined through various valuation techniques, including market and income approaches as considered necessary. Indefinite-lived intangible assets are not amortized; however, they are tested at least annually for impairment or more frequently if events or changes in circumstances exist that may indicate impairment. Initially, qualitative factors are considered to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount. If, through this qualitative assessment, the conclusion is made that it is more likely than not that an indefinite-lived intangible asset’s fair value is less than its carrying amount, a quantitative impairment analysis is performed by comparing the indefinite-lived intangible asset’s carrying amount to its fair value. The fair value for indefinite-lived intangible assets is determined through various valuation techniques, including market and income approaches as considered necessary. The amount of any impairment is measured as the difference between the carrying amount and the fair value of the impaired asset. During 2024, 2023, and 2022, no impairment of indefinite-lived intangible assets was recorded. Investment in Equity Securities Equity securities (“securities”) without readily determinable fair value that are not eligible to be measured in accordance with the net asset value practical expedient qualify for an election to initially estimate fair value using the measurement alternative at its cost. During 2020, the Company entered into a strategic collaboration and made a minority investment in a privately held company, which totaled $20,000 and is included in the “Other assets” line item on the Company’s consolidated balance sheets. The Company, at the time of the investment, elected to apply the measurement alternative, which may be applied to an equity interest on an instrument-by-instrument basis. Dividends received are reported in earnings. The value of the securities are remeasured to fair value if the securities are impaired or if observable price changes occur. These events are continually monitored and assessed at each reporting period. If a readily determinable fair value becomes available for the securities or observable price changes for the identical or a similar investment of the same issuer occur, the securities are remeasured at fair value as of the date the observable change occurred. Any resulting gains or losses on the securities for which the observable price changes occur will be recorded in net earnings. During 2024, no such observable price changes occurred. During 2023, the Company evaluated an observable price change related to equity securities without readily determinable fair values. No adjustment to the carrying value of the securities was necessary based on the observable price change. At each reporting period a qualitative assessment is made to consider impairment indicators to determine whether the securities are impaired. Impairment indicators may include but are not limited to earnings performance, business prospects by the investee, cash flows from operations, working capital, and noncompliance with debt covenants. If this qualitative assessment indicates impairment, fair value is determined and an impairment loss equal to the difference between the fair value of the investment and its carrying amount is recognized in net income. During 2024, 2023, and 2022, no impairment of securities was recorded. Nonqualified Deferred Compensation In 2021, the Company created a non-qualified deferred compensation plan for a select group of management and highly compensated individuals. The plan permits the deferral of up to 50% of a participant's base salary and/or 80% of a participant's annual incentive bonus. The deferrals are held in an irrevocable rabbi trust (the "Rabbi Trust"), which has been established to administer the plan. The Rabbi Trust is intended to be used as a source of funds to match respective funding obligations to participants. The assets of the trust are subject to the claims of the Company's creditors in the event that the Company becomes insolvent. Consequently, the Rabbi Trust qualifies as a grantor trust for income tax purposes. The Company makes periodic payments into company-owned life insurance policies held in this Rabbi trust to fund the expected obligations arising under this plan. There are no contractual restrictions on the Company's ability to surrender a policy. The assets and liabilities of the plan are included in "Other assets" and "Other long-term liabilities" respectively in the consolidated balance sheets. Changes in the deferred compensation balances are recorded to compensation expense and reflected within the "Selling, general and administrative" line in the consolidated statements of comprehensive income. As USANA HEALTH SCIENCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share data) NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED F-13

of December 28, 2024 and December 30, 2023, the trustee held total assets of $4,336 and $2,962, and deferred compensation liabilities of $4,684, and, $3,137, respectively. Self-Insurance The Company is self-insured, up to certain limits, for employee group health claims. The Company has purchased stop-loss insurance for the United States markets on both an individual and an aggregate basis, which will reimburse the Company for individual claims in excess of $175 and aggregate claims that are greater than $13,635. A liability is accrued for all unpaid claims. Total self-insurance expense was $13,842, $14,501, and $13,413 in 2024, 2023, and 2022, respectively. Derivative Financial Instruments The Company’s risk management strategy includes the select use of derivative instruments to reduce the effects of volatility in foreign currency exchange exposure on operating results and cash flows. In accordance with the Company’s risk management policies, the Company does not hold or issue derivative instruments for trading or speculative purposes. The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. When the Company becomes a party to a derivative instrument and intends to apply hedge accounting, the Company formally documents the hedge relationship and the risk management objective for undertaking the hedge, the nature of risk being hedged, and the hedged transaction, which includes designating the instrument for financial reporting purposes as a fair value hedge, a cash flow hedge, or a net investment hedge. The Company also documents how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method used to measure ineffectiveness. The Company periodically uses derivative instruments to hedge the foreign currency exposure of its net investment in foreign subsidiaries into U.S. dollars. Initially, the Company records derivative assets on a gross basis in its consolidated balance sheets. Subsequently the fair value of derivatives is measured for each reporting period. The effective portion of gains and losses attributable to these net investment hedges is recorded to foreign currency translation adjustment (“FCTA”) within accumulated other comprehensive income (loss) (“AOCI”) to offset the change in the carrying value of the net investment being hedged, and will subsequently be reclassified to net earnings in the period in which the hedged investment is either sold or substantially liquidated. During 2024 and 2023, the Company entered into and settled a European option with notional amounts of $77,345 and $81,343, respectively. During 2022 the Company entered into and settled a forward contract with a notional amount of $98,930. Both the European options and the forward contract were designated as net investment hedges. The Company realized gains of $255, $2,504, and $4,555 in 2024, 2023, and 2022, respectively. These gains were recorded to FCTA within AOCI. The Company assessed hedge effectiveness under the forward rate method, determining the hedging instruments were highly effective. As of December 28, 2024 and December 30, 2023, there were no derivatives outstanding for which the Company has applied hedge accounting. Subsequent to December 28, 2024, on January 14, 2025 the Company entered into an option contract designated as a net investment hedge with a notional amount of $70,062. Common Stock Share Repurchases The Company has a stock repurchase plan in place that has been authorized by the Board of Directors. As of December 28, 2024, $61,703, inclusive of accrued excise tax, is available to repurchase shares under this plan. The excess of the repurchase price over par value is allocated between additional paid-in capital and retained earnings on a pro-rata basis. There currently is no expiration date on the remaining approved repurchase amount and no requirement for future share repurchases. Revenue Recognition Revenue is recognized when, or as, control of a promised product or service transfers to a customer, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring those products or services. Revenue excludes taxes that have been assessed by governmental authorities and that are directly imposed on USANA HEALTH SCIENCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share data) NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED F-14

revenue-producing transactions between the Company and its customers, including sales, use, value-added, and some excise taxes. Revenue recognition is evaluated through the following five-step process: 1) identification of the contract with a customer; 2) identification of the performance obligations in the contract; 3) determination of the transaction price; 4) allocation of the transaction price to the performance obligations in the contract; and 5) recognition of revenue when or as a performance obligation is satisfied. Product Revenue A majority of the Company’s sales are for products sold at a point in time and shipped to customers, for which control is transferred to the customer as goods are delivered to the third party carrier for shipment. The Company receives payment, primarily via credit card, for the sale of products at the time customers place orders and payment is required prior to shipment. The Company does not recognize assets associated with costs to obtain or fulfill a contract with a customer. The Company’s product sales contracts include terms that could cause variability in the transaction price for items such as discounts, product promotions, credits, or sales returns, which are a reduction of revenue. Accordingly, the transaction price for product sales includes estimates of variable consideration to the extent it is probable that a significant reversal of revenue recognized will not occur. At the time of sale, the Company estimates a refund liability for the variable consideration based on historical experience, which is recorded within the “Other current liabilities” line item in the consolidated balance sheets. Initial product orders with a new direct selling customer may include multiple performance obligations related to sales discounts earned under the Company’s initial order reward program. Under this program, the customer receives an option to apply the discounts earned on the initial order to two subsequent Auto Orders, which conveys a material right to the customer. As such, the initial order transaction price is allocated to each separate performance obligation based on its relative standalone selling price and is recognized as revenue as each performance obligation is satisfied. Associate incentives represent consideration paid to an Associate for distinct services provided in the sale of the Company's products and include all forms of commissions, and other incentives paid to our Associates. The Company may provide Associate incentive promotions which are earned by Associates for distinct services rendered. Associate incentive promotions are recorded as the incentives are earned by the Associates. With the exception of commissions paid to Associates on personal purchases, which are considered a sales discount and are reported as a reduction to net sales, Associate incentives are recorded as an operating expense. The amounts paid to Associates are commensurate with the fair value received for the distinct services rendered by Associates and are recorded as an operating expense when revenue for the goods is recognized. Shipping and handling activities are performed upon delivery to the third party carrier for shipment. The Company accounts for these activities as fulfillment costs. Therefore, the Company recognizes the costs of these activities when revenue for the goods is recognized. Shipping and handling costs are included in cost of sales for all periods presented. With respect to will-call orders, the Company periodically assesses the likelihood that customers will exercise their contractual right to pick up orders and revenue is recognized when the likelihood that customers will pick up orders becomes remote. Other Revenue Other types of revenue include fees, which are paid by the customer at the beginning of the service period, for access to online customer service applications and annual account renewal fees for Associates, for which control is transferred over time as services are delivered and are recognized as revenue on a straight-line basis over the term of the respective contracts.

The following table presents Other Revenue for the periods indicated: Year Ended 2024 2023 2022 Other Revenue $ 2,356 $ 3,177 $ 3,452 Revenue Disaggregation Disaggregation of revenue by geographical region and major product line is included in Note M – Segment Information. Contract Balances When the timing of our provision of goods or services is different from the timing of the payments made by our customers, we recognize either a contract asset (performance precedes contractual due date) or a contract liability (customer payment precedes performance). Contract liabilities relate to deferred revenue for product sales for customer payments received in advance of shipment, for outstanding material rights under the initial order program, and for services where the performance obligations are satisfied over time as services are delivered. Contract liabilities are recorded as deferred revenue within the "Other current liabilities" line item in the consolidated balance sheets. The Company typically does not have contract assets based on the payment terms included in the Company’s contracts and the balance of contract assets was $0 at December 28, 2024 and December 30, 2023. The following table provides information about contract liabilities from contracts with customers, including significant changes in the contract liabilities balances during the period. December 28, 2024 December 30, 2023 Contract liabilities at beginning of period $ 13,910 $ 20,875 Increase due to deferral of revenue at period end 12,050 13,910 Decrease due to beginning contract liabilities recognized as revenue (13,910) (20,875) Contract liabilities at end of period $ 12,050 $ 13,910 Product Return Policy All product orders that are unused and returned within the first 30 days following purchase are refunded at 100% of the sales price. All product orders that are unused and resalable are refunded up to one year from the date of purchase at 100% of the sales price. This standard policy differs for Hiya, for which returns are allowed only in specific situations. To be considered, a return must be unopened in its original packaging and postmarked within 10 days of the original delivery date. This standard policy also differs in a few of our international direct selling markets due to the regulatory environment in those markets. Depending upon the conditions under which product was returned, customers may either receive a refund based on their original form of payment, or credit on account for a product exchange. The Company monitors Associate activity to ensure that all such practices are in line with established Company policies. Product returns totaled approximately 0.6%, 0.6%, and 0.7% of net sales in 2024, 2023, and 2022, respectively. Associate Incentives Associate incentives expenses include all forms of commissions, and other incentives paid to our Associates, less commissions paid to Associates on personal purchases, which are considered a sales discount and are reported as a reduction to net sales. USANA HEALTH SCIENCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share data) NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED F-16

Selling, General and Administrative Selling, general and administrative expenses include wages and benefits, depreciation and amortization, rents and utilities, Associate event costs, advertising and professional fees, marketing, and research and development expenses. Equity-Based Compensation The Company records compensation expense in the Financial Statements for equity-based awards based on the grant date fair value, which for restricted stock units is the closing market value of the Company’s common stock on the date of the grant. The grant date fair value of each stock-settled stock appreciation right is based upon the Black-Scholes option pricing model. The grant date fair value of each performance share unit is based upon a Monte-Carlo simulation in order to incorporate market conditions. Equity-based compensation expense for restricted stock units and stock-settled stock appreciation rights are recognized under the straight-line method over the period that service is provided, which is generally the vesting term. Equity-based compensation expense for performance stock units is recognized based on the achievement of certain performance and market conditions by specified target dates, subject to continued service through the applicable vesting dates. The probability of the awards meeting the performance condition is not included in the grant date fair value, but is estimated quarterly for expense recognition. The Company recognizes an adjustment to compensation expense based on revisions in probability assessments. The Company accounts for forfeitures as they occur. Further information regarding equity awards can be found in Note L – Equity-Based Compensation. Advertising Advertising costs are charged to expense as incurred and are presented as part of the “Selling, general and administrative” line item. Advertising expense totaled $4,967, $4,756, and $5,053, in 2024, 2023, and 2022, respectively. Research and Development Research and development costs are charged to expense as incurred and are presented as part of the “Selling, general and administrative” line item. Research and development expense totaled $11,571, $11,446, and $11,563 in 2024, 2023, and 2022, respectively. Earnings Per Share Basic earnings per common share ("EPS") are based on the weighted-average number of common shares that were outstanding during each period. Diluted EPS include the effect of potentially dilutive common shares calculated using the treasury stock method, which include in-the-money, equity-based awards that have been granted but have not been issued. When there is a loss, potential common shares are not included in the computation of diluted EPS, because to do so would be anti-dilutive. Recent Accounting Pronouncements Adopted Accounting Pronouncements In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The standard was intended to provide financial statement users with more disaggregated expense information about a public entity’s reportable segments. ASU 2023-07 requires incremental disclosures related to a public entity’s reportable segments including allowing the disclosure of multiple measures of segment profit or loss, requiring the disclosure of significant segment expenses, and requiring the qualitative disclosure of other segment items. ASU 2023-07 was adopted on a retrospective basis and did not have a material impact on the Company's financial position, results of operations, or cash flows as the standard only impacts financial statement footnote disclosures. For additional information, refer to Note M, "Segment Information". USANA HEALTH SCIENCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share data) NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED F-17

Issued Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The standard is intended to benefit investors by providing more detailed income tax disclosures. ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company is currently evaluating the impact adoption of the standard will have on its consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-04): Expense Disaggregation Disclosures. The standard is intended to provide investors with more decision-useful information about a public business entity's expenses by improving disclosures on income statement expenses through disclosure of disaggregated information about specific natural expense categories underlying certain relevant income statement expense line items that include one or more of five natural expense categories. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company is currently evaluating the impact that adoption of the standard will have on its consolidated financial statements. No other recent accounting pronouncements had, or are expected to have, a material impact on the Company's consolidated financial statements. NOTE B— BUSINESS COMBINATIONS On December 23, 2024, the Company entered into a merger agreement with Hiya, a leading direct-to-consumer provider of high-quality children's health and wellness products, by which the Company acquired a 78.85% controlling ownership interest. The primary reasons for the acquisition was to broaden USANA's reach into the highly attractive direct- to-consumer channel driven by Hiya's powerful subscription model with runway for sustainable future growth. The total purchase price consideration for Hiya was $206,161 in cash, which is inclusive of a working capital adjustment relative to a targeted working capital amount in the merger agreement. The purchase price consideration is preliminary as the working capital adjustment is being finalized. The Company incurred acquisition-related costs of approximately $8,243 for the year ended December 28, 2024, which are included in selling, general and administrative expenses in the accompanying consolidated statements of comprehensive income. The fair value for the acquired trade name intangible asset was estimated utilizing an income approach, specifically the multi-period excess earnings method. The fair value for the acquired customer relationship intangible asset was estimated utilizing an income approach, specifically the with-and-without method. Both methods involve the use of significant estimates and assumptions including projected revenue growth rates, projected earnings before interest, taxes, depreciation and amortization (“EBITDA”) margins, and discount rates. The following table summarizes the consideration transferred to acquire the 78.85% controlling ownership interest in Hiya and the estimated fair value of the assets acquired, liabilities assumed, and noncontrolling interest at the acquisition date: USANA HEALTH SCIENCES, INC.

Amounts Recognized as of the Acquisition Date Fair value of consideration transferred Cash consideration $ 206,161 Recognized amounts of identifiable assets acquired and liabilities assumed Cash and cash equivalents $ 3,603 Inventories 11,050 Other current assets 1,753 Intangibles 124,200 Operating lease right-of-use assets 383 Property and equipment 247 Other long-term assets 31 Total assets acquired $ 141,267 Accounts payable (3,313) Other current liabilities (4,566) Operating lease liabilities (408) Total liabilities assumed (8,287) Total identifiable net assets $ 132,980 Redeemable noncontrolling interest 54,193 Goodwill $ 127,374 The fair value of the noncontrolling interest of 21.15% was determined using the implied enterprise value based on the purchase price less a discount for lack of control. The Company recognized goodwill of $127,374. The goodwill reflects the expected future benefits of certain synergies and acquired assembled workforce and is expected to be deductible for income tax purposes. All of the goodwill was assigned to our Hiya direct-to-consumer segment. The revenue and earnings of the acquired business, since the acquisition date, have been included in the Hiya direct-to-consumer segment, and are not material to the consolidated results since the acquisition occurred near year end. Acquired intangible assets are being amortized over the estimated useful lives on a straight-line basis. The following table summarizes the estimated fair value and weighted average useful lives: Fair Value Weighted Average Estimated Useful Life Trade name $ 69,500 10.0 Customer relationship 54,700 5.0 Total intangible assets $ 124,200 USANA HEALTH SCIENCES, INC.

The higher effective tax rate can be attributed to lower consolidated earnings partially due to costs associated with the Hiya Acquisition, China's increased relative share of taxable income, and a valuation allowance placed on deferred tax assets in India, partially offset by a change in U.S. tax law for foreign currency conversion of foreign branch operations.

If unused, these carryforwards will expire between 2026 and 2034. The Company has generated excess foreign tax credits since the Tax Cuts and Jobs Act of 2017 was enacted on December 22, 2017. This is due to the U.S. tax rate being lower than most foreign taxing jurisdiction rates where the Company operates. Although the Company can claim foreign tax credits against U.S. source income due to overall domestic losses generated in previous years, the Company does not believe it will be able to use more foreign tax credits than it generates in a single year. The Company believes these foreign tax credit carryforwards will expire unused based on available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, available tax planning strategies, and available carryback opportunities. Similar with prior years, the Company continues to maintain a full valuation allowance on its foreign tax credit carryforwards. Valuation allowances are determined using a more-likely-than-not realization criteria and are based upon all facts and circumstances. USANA HEALTH SCIENCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share data) NOTE E—INCOME TAXES - CONTINUED F-23

The Company recorded a $1,531 valuation allowance on mirrored deferred tax assets recorded in the United States, which offset deferred tax liabilities of foreign disregarded entities. These mirrored deferred tax assets represent future foreign tax credits. This valuation allowance is necessary because the Company is limited in its ability to utilize future foreign tax credits due to the U.S. tax rate being lower than most foreign taxing jurisdiction rates where the Company operates. The Company also had $1,769 of Utah research credit carryforwards, and $2,375 of Federal research credit carryforwards as of December 28, 2024. If unused, the Utah research credit carryforwards expire between 2027 and 2038, and the Federal research credits expire between 2036 and 2044. Utah research credits are limited to Utah tax due and the Company has a history of generating more credits than it can use. Federal research credit carryforwards can only be used in a year when U.S. taxes are owed after foreign tax credits have been applied. Due to the lack of sufficient evidence to the contrary, the Company has placed a full valuation allowance on these credit carryforwards. In addition, the Company had $7,626 of foreign operating loss carry forwards, $1,082 of which have an unlimited carryforward period. The deferred tax asset associated with these losses was $2,282 and a valuation allowance of $2,113 has been applied against this deferred tax asset. The 2024 deferred tax asset for state-tax-loss carryforwards was $67. If unused, some of the state-tax-loss carryforwards will expire between 2033 and 2043 and others can be carried forward indefinitely. The total combined valuation allowance was $156,669 as of December 28, 2024. The 2024 valuation allowance represents a $19,417 net increase from 2023. If the Company determines that there is sufficient evidence to remove the valuation allowances addressed above, the valuation allowance will be released and the provision for income taxes will be reduced. As of December 28, 2024, the cumulative amount of undistributed earnings of the Company’s non-U.S. subsidiaries held for indefinite reinvestment is approximately $4,000. If this amount were repatriated to the United States, the amount of incremental taxes would be approximately $400. As of December 28, 2024, the Company reported $153 in "Other current liabilities" and $1,034 in "Other long- term liabilities" for a combined total of $1,187 in unrecognized tax benefits that would impact the effective tax rate if recognized. This compares $1,074 of unrecognized tax benefits in "Other long-term liabilities" as of December 30, 2023. The following reconciliation provides the changes in unrecognized tax benefits for the years presented: Year Ended 2024 2023 2022 Beginning balance of unrecognized tax benefits $ 1,074 $ 1,450 $ 1,008 Increases related to prior year tax positions 43 30 107 Decreases related to prior year tax positions (69) (363) — Increases related to current year tax positions 139 409 468 Decreases for settlements with taxing authorities — (452) (133) Ending balance of unrecognized tax benefits $ 1,187 $ 1,074 $ 1,450 The Company accounts for interest and penalties associated with unrecognized tax benefits as a component of income tax expense. For the period ended December 28, 2024 and December 30, 2023, the Company reported $43 and $66, respectively, as income tax expense related to interest and penalties. As of December 28, 2024, the Company recorded $130 of "Other current liabilities" and $93 of "Other long-term liabilities" associated with interest and penalties for unrecognized tax benefits. This compares to $0 of "Other current liabilities" and $180 of "Other long-term liabilities" associated with interest and penalties reported as of December 30, 2023. The Company files income tax returns in the United States and foreign jurisdictions. In general, the Company's tax filings are subject to examination for years ended on or after December 31, 2020. However, statutes of limitations in some markets may be as long as ten years for transfer pricing related issues. USANA HEALTH SCIENCES, INC.

(“Bank of America”) as Administrative Agent, Swingline Lender and Letter of Credit Issuer, and the other lenders party thereto. On August 28, 2024, the Company entered into the Third Amendment to the Second Amended and Restated Credit Agreement ("Restated Credit Agreement"), which replaces the Bloomberg Short-Term Bank Yield Index rate with the Secured Overnight Financing Rate ("SOFR") and amends certain other defined terms. The Credit Agreement provides for a revolving credit limit for loans to the Company up to $75,000 (the “Credit Facility”). In addition, at the option of the Company, and subject to certain conditions, the Company may request to increase the aggregate commitment under the Credit Facility up to an additional $200,000. There was $23,000 and $0 outstanding debt on the Credit Facility as of December 28, 2024 and December 30, 2023, respectively. The obligations of the Company under the Credit Agreement are secured by the pledge of the capital stock of certain subsidiaries of the Company, pursuant to a Security and Pledge Agreement. USANA HEALTH SCIENCES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share data) NOTE H—GOODWILL AND INTANGIBLE ASSETS - CONTINUED F-28

Interest on revolving borrowings under the Credit Facility is computed at SOFR, adjusted by features specified in the Credit Agreement. The covenants require the Company’s rolling four-quarter consolidated EBITDA (as defined in the Credit Agreement) to be $100,000 or greater and its ratio of consolidated funded debt to consolidated EBITDA to be equal to or less than 2.0 to 1.0 at the end of each quarter. The Credit Agreement does not include any restrictions on the payment of cash dividends or share repurchases by the Company. Consolidated EBITDA and consolidated funded debt are non- GAAP terms. The Company will be required to pay any balance on this Credit Facility in full at the time of maturity in August 2025. The Company maintains local lines of credit across different markets to secure sufficient working capital. As of December 28, 2024 and December 30, 2023, the balance on these local lines of credit was $0 and $786, respectively. NOTE K—COMMITMENTS AND CONTINGENCIES Unconditional Purchase Obligations The Company’s unconditional purchase obligations relating to IT-related services and advertising agreements were $6,746 and $8,018, as of December 28, 2024 and December 30, 2023, respectively that are generally paid within one year. Contingencies The Company is involved in various lawsuits, claims, and other legal matters from time to time that arise in the ordinary course of conducting business, including matters involving its products, intellectual property, supplier relationships, distributors, competitor relationships, employees and other matters. The Company records a liability when a particular contingency is probable and estimable. The Company faces contingencies that are reasonably possible to occur; however, they cannot currently be estimated. While complete assurance cannot be given as to the outcome of these proceedings, management does not currently believe that any of these matters, individually or in the aggregate, will have a material adverse effect on the Company’s financial condition, liquidity or results of operations. It is reasonably possible that a change in the contingencies could result in a change in the amount recorded by the Company in the future. Employee Benefit Plan In the United States, the Company sponsors an employee benefit plan under Section 401(k) of the Internal Revenue Code. This plan covers employees who are at least 18 years of age and have met a one-month service requirement. The Company makes a matching contribution equal to 100 percent of the first one percent of a participant’s compensation that is contributed by the participant, and 50 percent of that deferral that exceeds one percent of the participant’s compensation, not to exceed six percent of the participant’s compensation, subject to the limits of ERISA. In addition, the Company may make a discretionary contribution based on earnings. The Company’s matching contributions cliff vest at two years of service. Contributions made by the Company to the plan in the United States were $2,422, $2,451, and $2,589 for the years ended 2024, 2023, and 2022, respectively. The Company has employees in international countries that are covered by various defined contribution plans. These plans are administered based upon the legal requirements in the countries in which they are established. NOTE L—EQUITY-BASED COMPENSATION Total equity-based compensation expense was $14,779, $14,965, and $13,485 for fiscal years 2024, 2023, and 2022, of which, $221, $370, and $154, was related to liability-classified awards, respectively.

The following table shows the remaining unrecognized compensation expense on a pre-tax basis for all types of unvested equity awards that are outstanding and expected to vest, as of December 28, 2024. This table does not include an estimate for future grants that may be issued. 2025 $ 10,973 2026 7,553 2027 4,093 2028 524 $ 23,143 The remaining unrecognized compensation expense above is expected to be recognized over a weighted-average period of 1.7 years. The Company's 2015 Equity Incentive Award Plan (the "2015 Plan") is currently the only plan under which equity awards are issued. The 2015 Plan allows for the grant of various equity awards including stock-settled stock appreciation rights, stock options, and restricted stock awards which include restricted stock units, deferred stock units, performance stock units, (collectively "restricted stock awards") and other types of equity-based awards to the Company’s officers, key employees, and non-employee directors. Since the inception of the 2015 Plan, 1,750 shares have been authorized. As of December 28, 2024, 4,613 awards had been granted under the 2015 Plan, of which 2,946 were stock-settled stock appreciation rights, and 1,667 were restricted stock awards. Of the 2,946 granted stock-settled stock appreciation rights, approximately 450 shares have been issued, 24 awards are outstanding and the remaining have been returned to the plan. As of December 28, 2024, a total of 1,305 options and grants had been forfeited and added back to the number of shares available for issuance under the 2015 Plan. Stock-Settled Stock Appreciation Rights The Company uses the Black-Scholes option pricing model to estimate the fair value of its stock-settled stock appreciation rights. The weighted-average fair value of stock-settled stock appreciation rights granted in 2024 and 2023 were $14.60 and $19.92, respectively. There were no stock-settled stock appreciation rights granted in 2022. Stock-settled stock appreciation rights granted to officers and key employees upon hire or promotion to such a position, or annually for existing participants, generally vest 25% each year on the anniversary of the grant date and expire 4.5 years from the date of grant. The following table includes the weighted-average assumptions the Company used to calculate the fair value of stock-settled stock appreciation rights that were granted during the periods indicated.

(2) Risk-free interest rate is based on the U.S. Treasury yield curve with respect to the expected life of the award. (3) Depending upon the terms of the award, one of two methods will be used to calculate expected life: (i) a weighted-average that includes historical settlement data of the Company’s equity awards and a hypothetical holding period, or (ii) the simplified method. (4) The Company historically has not paid and currently has no plan to pay dividends. USANA HEALTH SCIENCES, INC.

The total fair value of stock-settled stock appreciation rights that vested was $656, $1,009, and $983, for the years ended 2024, 2023, and 2022, respectively. During the years ended 2024 and 2023, there were no exercises of stock-settled stock appreciation rights. During the year ended 2022, certain employees elected to receive a net amount of shares upon the exercise of stock-settled stock appreciation rights in order to satisfy the Company’s tax withholding obligation. There was no reduction to additional paid- in capital for the years ended 2024, 2023, and 2022. Restricted Stock Awards Restricted stock awards include stock-settled and cash-settled restricted stock units, performance stock units granted to the Company’s officers and key employees, and deferred stock units granted to non-employee directors. Restricted stock units are granted to officers and key employees upon hire or promotion to such a position, or annually for existing participants, and generally vest 25% each year on the anniversary of the grant date. Awards of deferred stock units granted to non-employee directors generally vest 25% each quarter, commencing on the first vest date anniversary following the final vesting of the previous award. Upon vesting, holders of stock-settled restricted stock units and deferred stock units are entitled to receive shares of the Company’s common stock on a one-for-one basis. Holders of cash-settled restricted stock units are entitled to receive cash payments equivalent to the number of units held, valued at the closing market price on the vest date. The fair value of restricted stock units is determined based on the Company’s closing stock price on the date of grant. Cash-settled restricted stock units are accounted for as liability-classified awards and fair value is remeasured to the current fair value, which is the Company's closing stock price, at each reporting date until the award is settled at vesting. Restricted stock units are full-value shares at the date of grant, vesting over the periods of service, and do not have expiration dates. Performance stock units are granted to officers and key employees. The ultimate number of shares to be earned depends on the achievement of certain market and performance conditions, and continued service through the applicable vesting date, and do not have expiration dates.

A summary of the Company’s stock-settled restricted stock unit activity is as follows: Shares Weighted- average grant date fair value Outstanding at December 30, 2023 490 $ 71.35 Granted 328 49.84 Vested (195) 47.85 Forfeited (31) 61.95 Outstanding at December 28, 2024 592 $ 59.87 During the year ended 2024, certain employees elected to receive a net amount of shares upon the release of restricted stock units in order to satisfy the Company’s tax withholding obligation. This resulted in a reduction to additional paid-in capital of $3,223, $3,092, and $4,706 for the years ended 2024, 2023, and 2022, respectively, reflected as a financing activity in the Company’s consolidated statements of cash flows. The total fair value of restricted stock units that vested was $9,309, $9,293, and $12,808, for the years ended 2024, 2023, and 2022, respectively.

The number of deferred stock units vested and unreleased totaled 8, for the years ended 2024, 2023, and 2022, respectively. There were no deferred stock units that vested in 2024, 2023, and 2022. During 2024, the Company granted no performance stock units to officers and key employees. The performance stock units are subject to a cliff vesting at the end of a three-year period. The number of units that vest will vary between 0% - 200% based on the achievement of market and performance conditions, over the three-year service period. The fair value of the performance stock units is determined using a Monte-Carlo simulation model. A Monte-Carlo simulation model uses stock price volatility and other assumptions to estimate the probability of satisfying the market conditions and the resulting fair value of the award. The weighted-average grant date fair value of performance stock units granted in 2023 was $40.05. There were no performance stock units granted in 2024 or 2022. In 2024 and 2023, there was unrecognized compensation expense of $2,025 and $913 related to unvested performance stock units that are not probable of achieving the performance condition. The following table includes the weighted-average assumptions the Company used to calculate the fair value of performance stock units that were granted during the periods indicated.

For purposes of this performance condition, "active Customer" is defined as active Customer in the Company’s direct selling operating segment (discussed further in Note M – Segment Information below), excluding customers from mergers and acquisitions. NOTE M—SEGMENT INFORMATION The Company primarily operates as a global nutrition, personal health and wellness company that develops and manufactures high quality, science-based nutritional, and personal care products. As of December 28, 2024, the Company had two reportable segments: direct selling and Hiya direct-to-consumer. Management identifies segments based upon the Company's organizational and management reporting structure. The direct selling segment develops and manufactures high quality, science-based nutritional, personal care and skincare products with a primary focus on promoting long-term health and wellness in various geographic markets worldwide that are distributed through the direct selling channel. The Hiya direct-to-consumer segment is a new reportable segment in 2024 resulting from the Hiya Acquisition during 2024. Hiya is a leading provider of high-quality children’s health and wellness products in the U.S. that are distributed through the direct- to-consumer channel. Additionally, the Company has operating segments that are not material and included as a component of “Other”. The operating segments reflect the Company's primary sales channels and represent the way the chief operating decision maker ("CODM") evaluates the Company's business performance and allocates resources. The CODM is the Company's Chief Executive Officer. The CODM evaluates the performance of each segment based on segment earnings from operations in order to determine how to allocate the Company's resources across its operating segments, including allocating capital and personnel. The CODM does not evaluate operating segments using asset information, accordingly, the Company does not report asset information by segment. Summarized financial information for the Company’s reportable segments is shown in the following tables, including significant segment expenses that are regularly reviewed by the CODM.

NOTE O—REDEEMABLE NONCONTROLLING INTEREST December 23, 2024, the Company acquired a 78.85% controlling financial interest in Hiya. Simultaneously, USANA and the remaining noncontrolling interest holders entered into an Amended and Restated Limited Liability Company Agreement ("LLC Agreement"). The agreement granted USANA the right to buy ("Call Right") and the noncontrolling interest holders the right to cause USANA to purchase ("Put Right") half of the remaining noncontrolling interest units beginning on April 30, 2028, and the remaining unpurchased noncontrolling interest units beginning on April 30, 2030 or, if the Put Right and Call Right have not, collectively, been exercised with respect to all noncontrolling interest units prior to the end of 2030, the period beginning on April 30th of each year after 2030. The purchase price for the noncontrolling interest units pursuant to the Call Right and Put Right is based on Hiya’s Adjusted EBITDA (as defined in the LLC Agreement) for the calendar year immediately prior to the year in which such right is exercised, multiplied by the Company Value Reference Amount (as defined in the LLC Agreement). The Call Right and Put Right are not mandatorily redeemable. The redemption of the noncontrolling interest is contingent upon the passage of time and within the control of the interest holders, therefore, the Company has classified the noncontrolling interest as redeemable within the mezzanine section on the consolidated balance sheet. The noncontrolling interest was recognized and measured at fair value on the acquisition date. The Company records the redeemable noncontrolling interest at the greater of: (i) the carrying value, which is adjusted each period for the noncontrolling interests' share of net earnings or loss and distributions or (ii) the redemption value. The following is a reconciliation of the changes in the redeemable noncontrolling interest for the periods indicated: Beginning balance - December 30, 2023 $ — Recognition of Hiya redeemable noncontrolling interest 54,193 Net earnings attributable to redeemable noncontrolling interest 30 Ending balance - December 28, 2024 $ 54,223 USANA HEALTH SCIENCES, INC.

Dear Shareholders, We would like to thank you, our valued shareholders, for your continued support of USANA’s mission, which is centered on improving the health and wellness of individuals and families to create the healthiest family on earth. The following objectives are key to accomplishing this mission: 1. Providing the highest-quality and best-in-class nutritional products to our customers around the world. 2. Growing our worldwide business by emphasizing active customer growth. 3. Offering an excellent customer experience. 4. Enhancing our global sustainability efforts by giving back through the efforts of employees, customers, and the USANA Foundation. Fiscal 2024 Results Full year operating results reflected continued, cautious consumer sentiment in many of our key Asia Pacific markets. This created a challenging environment to attract new customers and generate positive momentum throughout the year. Notwithstanding these factors, our commercial team made progress on several meaningful initiatives, which will begin rolling out across our direct sales business this year. We are confident these initiatives will lay the foundation for the Company to generate long-term growth. Repositioning for Future Growth During 2024, we pivoted to better address this dynamic operating environment by reorganizing our sales, marketing, and communications departments into one commercial team. We believe this has better positioned us to execute our customer growth strategy in 2025, which is centered on our ability to deliver three fundamental benefits to our sales force: (1) best-in-class products, (2) a simple brand message that highlights the superiority, differentiation, and benefits of these products, and (3) an income opportunity that is simple, rewarding, and worthy of our Associates' time and effort. Accordingly, our commercial team is comprised of three core global teams: Product, Brand, and Opportunity, as well as our regional and local business units. We saw notable and tangible benefits from the commercial team in 2024, including the launch of our Celavive Resurfacing Serum and Whey Protein Isolate products. These product launches are illustrative of the early stages of our product innovation strategy, which includes increasing the cadence of new and upgraded high-quality, relevant, and premium products. We also completed our acquisition of Hiya Health in the fourth quarter, which is a meaningful milestone for USANA and an exciting addition to our business. Hiya is a growing, highly cash generative, direct-to-consumer children’s wellness brand. Hiya has an experienced management team that continues to lead the company and a compelling subscription business model we believe is positioned to deliver long-term sustainable growth over the next several years. We look forward to supporting Hiya as they build upon their leadership position in the children’s health and wellness market. Enhancing the Experience Providing the best customer experience and increasing the number of active customers in our business continue to be our top priorities, and in 2025 we plan to execute on the following strategies to accomplish our goals: • A higher cadence of new product launches and improved existing products tailored to local markets. • Strategic enhancements and modifications to our Associate incentive offering, which are intended to incent customer growth and improve pay for performance. • Strengthening our brand messaging, story, and value proposition; and • Accelerating Associate engagement activities in our regions around the world. Giving Back The USANA Foundation, which is the charitable arm of our business, continued to fulfill its mission of providing immediate and long-term global food relief for those in severe need. The foundation carries out its mission by leading a network of community-driven partnerships to nourish those in need, equip individuals to better nourish themselves, and help eliminate hunger throughout the world. In 2024, the USANA Foundation provided, among other things: • Over 30 million meals. • Aid and grants to partner charities around the world. • Backpacks of food for at risk children in local schools to take home on the weekend and during long holiday breaks; and • Children's vitamins to some of the most malnourished children around the world. Our team is proud of the positive impact we are having around the world. We are improving individuals’ health through our exceptional health products, improving the financial health of our Associates through our business offering, and offering help to those in need through our charitable efforts. I am confident we will have an even larger impact as we continue to execute on our strategies to strengthen and grow our global business. We thank our customers, Associate sales force, employees, and other stakeholders for their significant contributions to this mission.
