1.10USD+3.77% · 1 dayClose 04 Nov 2026

Natural Alternatives International formulates, manufactures and markets nutritional supplements, mainly through private-label contract manufacturing for customers who sell via direct sales and e-commerce. The company grew sales in fiscal 2026 but posted a net loss of 20.7 million USD, and an expected breach of a credit covenant plus substantial doubt about going concern make the situation fragile. With net sales of 142.5 million USD, that loss highlights pressure on profitability.

At the close of 04 Nov 2026, Natural Alternatives International, Inc. (NAII) stock was 1.10 USD (+3.77% on the day), with market capitalisation 24.3 m USD, beta 0.47, 52-week range 1.06–4.83 USD. Latest reported quarter (Q4 2026): revenue of 34.5 m USD (+1.9% YoY), net income of -13.5 m USD, diluted EPS -2.23 USD.

Valuation methods

  • DCF (discounted cash flow)unavailable · the reported interest expense is far older than the latest period (the filer changed its XBRL tag): a stale figure is not used
  • Peers: EV/EBITDAunavailable · net debt missing: EV cannot be bridged to equity (missing debt is not zero)

    AI analysis

    AI-generatedAI-generated analysis (Claude) from cited public sources; it may contain errors. Not investment advice. As of 27 Oct 2026 · Model: claude-haiku-5-5.

    In brief

    Natural Alternatives International formulates, manufactures and markets nutritional supplements, mainly through private-label contract manufacturing for customers who sell via direct sales and e-commerce. The company grew sales in fiscal 2026 but posted a net loss of 20.7 million USD, and an expected breach of a credit covenant plus substantial doubt about going concern make the situation fragile 1. With net sales of 142.5 million USD 1, that loss highlights pressure on profitability.

    SWOT

    Strengths

    • The company holds multiple manufacturing certifications, including NSF, SSCI, organic and Swissmedic, supporting relations with existing customers 1.
    • Its beta-alanine patent and trademark estate provides a point of differentiation and licence revenue 1.
    • Integrated formulation, research, regulatory and packaging services are hard for smaller competitors to replicate 1.

    Weaknesses

    • The company depends heavily on a few large customers, and losing one would have a significant impact 1.
    • Underused factory capacity led to an impairment and an operating loss in fiscal 2026 1.
    • The company is expected to breach a credit covenant, and there is substantial doubt about going concern 1.

    Opportunities

    • The CarnoSyn® 4X and TriBsyn® launches could open wellness and healthy ageing markets 1.
    • Expansion into medical nutrition and beverage or dairy formats could increase demand for patented ingredients 1.
    • Selling surplus property could bring in cash to reduce debt 1.

    Threats

    • Inflation and tariffs could cut margins if costs cannot be passed on to customers 1.
    • Intense competition and low entry barriers could lead to price cuts and lost market share 1.
    • Negative publicity about supplement safety could hurt sales across the sector 1.

    Risks

    • Credit covenant breachhigh

      The company has said it will not be able to meet a fixed charge coverage covenant at September 30, 2026, and a waiver from the lender is not assured 1.

    • Going concern doubthigh

      Management acknowledges substantial doubt about the company's ability to continue as a going concern if results do not improve or property sales do not succeed 1.

    • Customer concentrationhigh

      Losing one of the two major customers could significantly harm the financial position 1.

    • Underused factoriesmedium

      Idle capacity has already caused an impairment, and a sale of the Carlsbad plant could take a long time 1.

    • Geopolitical and supply chain disruptionmedium

      Conflicts in the Middle East and Eastern Europe could disrupt ingredient supply and ocean freight 1.

    Investment thesis

    What would need to be true (bull case)

    • Sales grew in fiscal 2026, and larger orders from existing customers show that private-label manufacturing can still expand 1.
    • The new CarnoSyn® 4X and TriBsyn® products could open untapped segments and support licence revenue over the long term 1.
    • Multiple certifications and a quality reputation could help attract new customers if the customer base is diversified 1.

    What would break the thesis

    • The large net loss and asset impairment show the business is not yet profitable, and a further loss is expected in fiscal 2027 1.
    • The covenant breach and going concern doubt could limit access to financing and could force asset sales on unfavourable terms 1.
    • Dependence on a few large customers leaves revenue exposed to sudden changes in their orders 1.

    Products, market & competition

    AI-generatedAI-generated analysis (Claude) from cited public sources; it may contain errors. Not investment advice. As of 27 Oct 2026 · Model: claude-haiku-5-5.

    The business

    Natural Alternatives International, Inc. (NAI) is a formulator, manufacturer and marketer of nutritional supplements, based in Carlsbad, California 1. Its primary activity is private-label contract manufacturing for companies that sell vitamins, minerals and plant-based supplements within and outside the U.S. 1. The company also owns a patent estate for beta-alanine, sold under the CarnoSyn®, SR CarnoSyn®, CarnoSyn® 4X and TriBsyn® trademarks 1.

    Manufacturing is concentrated in Vista and Carlsbad, California, and at the Manno, Switzerland facility of subsidiary NAIE 1. The facilities hold GMP registrations, NSF Certified for Sport, USDA organic and SSCI certifications, and the Swiss site is licensed by Swissmedic 1. Management aims to improve profitability by consolidating factories and improving operational efficiency 1.

    Long-term strategy seeks to diversify the sales base, attract quality-oriented customers and expand beta-alanine commercialization in sports nutrition, wellness and medical food 1. In fiscal 2026 the company launched CarnoSyn® 4X and TriBsyn® expansions, while patents for instant-release beta-alanine expired in July 2026 1.

    Segments

    Private-label contract manufacturing

    This segment produced about 94% of net sales, or 134.6 million USD in fiscal 2026, up 11% from the prior year 1. The growth came mainly from larger orders from one of the largest customers 1.

    Patent and trademark licensing

    This segment contributed 7.9 million USD in fiscal 2026, down 2% from the prior year, due to lower beta-alanine raw material sales to existing customers 1. Its royalty and licence revenue depends on growing demand for SR CarnoSyn®, CarnoSyn® 4X and TriBsyn® 1.

    Market context

    The company operates in the nutritional supplement market, which is fragmented and competitive, with products sold through drug stores, supermarkets, e-commerce, natural food stores and direct sales channels 1. Demand depends heavily on the direct sales channel, through which many of NAI's customers sell 1. Economic conditions, inflation and geopolitical tensions could affect consumer demand and raw material costs 1.

    The company expects upward pricing pressure on raw materials and packaging to continue in fiscal 2027, driven by tariffs and transport costs 1. Conflicts in the Middle East and Eastern Europe could affect the availability of certain ingredients 1.

    Trends

    • Inflationary cost pressureheadwind

      Higher labour, transport, energy and tariff costs could compress margins if they cannot be passed on to customers 1.

    • Growth in new product formatstailwind

      The launch of CarnoSyn® 4X and TriBsyn® could open new consumer segments such as older adults, vegetarians and vegans 1.

    • Geopolitical instabilitymixed

      Conflicts in the Middle East and Eastern Europe affect the price and availability of some raw materials and ocean freight, although the company has largely found alternative sources 1.

    • Reliance on a few large customersheadwind

      Concentrated sales to two major customers could hurt results sharply if one reduces orders, as happened after a downward forecast revision 1.

    Competitive position

    The company competes with other manufacturers, distributors and marketers of supplements, many of which are private and larger, with greater financial resources and brand recognition 1. Entry barriers are relatively low, and new products can quickly capture market share 1.

    NAI says it differentiates itself through comprehensive customer services, certified manufacturing, a commitment to quality and its research and development 1. The source does not identify publicly listed U.S. competitors, so no listed competitor tickers can be given 1.

    • Private supplement contract manufacturers

      Larger, mostly unlisted rivals that are not subject to public-company disclosure and may compete on price 1.

    • Direct-sales supplement distributors

      Companies selling supplements through network marketing and internet channels, where brand and promotion matter 1.

    • Retail supplement sellers

      Drug store chains, supermarkets and natural food stores selling own-label or third-party supplements 1.

    • Beta-alanine and ingredient producers

      Ingredient suppliers that may compete in the raw material market for beta-alanine 1.
