Silver
as an Antimicrobial

Our
patented molecule, SDC, represents one of the first significant advancements in antimicrobials in decades. SDC is an electrolytically
generated source of stabilized ionic silver, making it a versatile foundation for a variety of products across diverse markets. Colorless,
odorless, tasteless and non-caustic, the aqueous SDC formulates well with other compounds. We produce and market pre-formulated, ready-to-use
product, as well as varying strengths of SDC concentrate as an additive or raw material for inclusion in other products.

Stability

SDC
is a stabilized silver ion complex with a shelf life of several years. The unique bond between the silver ion in SDC allows the silver
ion to remain in solution while at the same time making it more bio-available for antimicrobial action.

Mode
of Action

SDC
kills microorganisms by two modes of action: 1) the silver ion deactivates structural and metabolic membrane proteins leading to microbial
death; and 2) the microbes view SDC as a food source, allowing the silver ion to enter the microbe. Once inside the organism, the silver
ion denatures the deoxyribonucleic acid, or DNA, which halts the microbe’s ability to replicate and leads to its death. This dual
action makes SDC highly and quickly effective against a broad spectrum of microbes.

Safety
and Toxicity Categories

SDC
is non-toxic, non-caustic, colorless, odorless, tasteless and does not produce toxic fumes. While SDC is highly toxic to bacteria, fungi
and viruses it is non-toxic to humans and animals. Based on the EPA toxicity categorization of antimicrobial products at use dilutions,
that range from Category I (high toxicity) down to Category IV (no/low toxicity), SDC is rated in the lowest toxicity category, Category
IV, while traditional disinfectants fall into Categories I and II.

The
following table shows the EPA toxicity categories and required signal words.

Limitations
of Existing Food Safety Solutions

The
United States, or U.S., food industry continues to rely on the use of toxic chemicals as processing aids or interventions during food
processing operations for which pathogens are becoming increasingly resistant and rendering current interventions less efficacious. Most
of these chemicals carry various warning labels for their toxic and/or caustic characteristics, which can negatively affect the safety
of processing plant personnel, plant operating equipment and the plant environment and its surroundings.

Currently
used chemicals in food processing include peracetic acid, acidified sodium chlorite, ozone, and chlorine dioxide. Some of these chemicals
can be difficult to work with as a processing aid as they require heating to become effective or are difficult to mix and stabilize prior
to use. Some of these chemicals damage the food being processed, leading to reduced yields and their effectiveness is often limited to
specific pathogens or foods. Additionally, some of these chemicals can produce noxious fumes that over time have been linked to upper
respiratory illness and typically require in-plant decontamination of their effluence.

Natural
and Environmentally Responsible

SDC
is made of simple and all-natural ingredients: water, citric acid and minute amounts of ionic silver. SDC does not present a threat to
the environment. If introduced to wastewater systems, the low concentrations of ionic silver in SDC would react with naturally present
substances such as chlorides, sulfides and organic matter. These reactions would create insoluble silver complexes and render the silver
inert. In addition, SDC is manufactured through a “zero waste” process in which no byproducts or environmental effluent are
created.

Intellectual
Property

We
actively protect our technology, inventions, and improvements through patents, trademarks, and trade secrets. We currently hold twelve
U.S. patents. We intend to focus our future patent prosecution and defense efforts primarily to North America, Europe, Asia and Mexico.

Although
we believe that we have developed our technology independently and have not infringed, and do not infringe, on the patents of others,
third parties may make claims that our technology does infringe on their patents or other intellectual property. In the event of infringement,
we may, under certain circumstances, be required to modify our infringing product or process or obtain a license. We may not be able
to do either of those things in a timely manner if at all, and failure to do so could have a material adverse effect on our business.
In addition, we may not have the financial or other resources necessary to enforce a patent infringement or proprietary rights violation
action or to defend ourselves against such actions brought by others. If any of the products we develop infringe upon the patent or proprietary
rights of others, we could, under certain circumstances, be enjoined or become liable for damages, which would have a material adverse
effect on our business. We also use confidentiality and nondisclosure agreements to safeguard proprietary information but recognizes
the risk of breaches or inadequacies in these agreements.

Additionally,
the Company holds registered trademarks for several brands, including PURE Bioscience®, PURE®, SILVÉRION®, Powered
by SDC Ag+® and PURE Control®. Some previously held trademarks have been abandoned as they no longer align with the Company’s
strategy.

Research
and Development

We
prioritize innovation as a key element of our business strategy and long-term success. We aim to leverage our technology platform to
create additional proprietary products and applications, including both end-use products and raw material formulations. Most research
and development activities are conducted in-house, complemented by independent testing from third-party laboratories. We also collaborate
with development partners who invest in specific product and process research using our SDC technology.

Sales
and Marketing

A
critical aspect of our business strategy is to leverage the industry experience of our internal sales force, the members of our Board
of Directors, or Board, and our management team in order to maximize the commercial potential of our technology platform in the food
industry. We are also working in tandem with numerous distribution partners to service existing customers and secure new customers.

Additionally,
we plan to form selective partnerships with industry leaders to enhance product commercialization both domestically and internationally,
leveraging partners’ resources for broader market reach. We believe our SDC-based products offer superior pathogen control compared
to traditional chemical solutions, which often have higher toxicity.

Sales
Concentration

Net
product sales were $2,315,000 and $2,198,000 for the fiscal year ended July 31, 2026 and 2025, respectively. The increase of $117,000
was attributable to increased sales across our end-user network servicing the food processing industry. Our top three customers accounted
for $824,000 of net product sales for the fiscal year ended July 31, 2026. For
the year ended July 31, 2026, one customer accounted for 24% of our net product sales. No other individual customer accounted for 10%
or more of our net product sales. There were no foreign sales during the fiscal year ended July 31, 2026.

From
time to time, one or a small number of our customers may represent a significant percentage of our revenue. Our largest customer accounted
for 24% of our revenue for the fiscal year ended July 31, 2026. Although we have agreements with many of our customers, these agreements
typically do not prohibit customers from purchasing products and services from competitors. A decision by any of our major customers
to significantly reduce the amount of product ordered or license fees paid, or their failure or inability to pay amounts owed to us in
a timely manner, or at all, could have a significant adverse effect on our business.

Competition

Since
SDC is a novel antimicrobial technology, our success hinges on gaining market share from established products. Even if SDC demonstrates
technological advantages, substantial investments are needed to displace traditional technologies offered by well-known industry leaders.

Moreover,
SDC-based products, particularly those with higher silver ion concentrations, are generally more expensive to produce than existing chemicals,
which may deter customers from purchasing them, despite their superior efficacy. Customers may also find that the benefits of SDC products
(such as being non-toxic and non-caustic) are insufficient to justify the higher costs compared to lower-priced alternatives.

Government
Regulation

Our
business is subject to various government regulations relating to the protection of public health and the environment. Among these are
laws that regulate the manufacture, storage, distribution and labeling of our products, as well as the use, handling, storage and disposal
of certain materials in the manufacturing of our products.

Requirements
Imposed by the EPA and Similar State Agencies

We
manufacture and sell in the U.S. certain disinfecting products that kill or reduce microorganisms (bacteria, viruses, fungi). The manufacture,
labeling, handling and use of these products are regulated by the EPA under the Federal Insecticide, Fungicide, and Rodenticide Act,
or FIFRA. We currently sell three products registered by the EPA under FIFRA, certain of which are approved for use on food contact surfaces
and others of which are approved for use on non-food contact hard surfaces. EPA product registration requires meeting certain efficacy,
toxicity and labeling requirements and paying ongoing registration fees.

Although
states do not generally impose substantive requirements different from those of the U.S. EPA, each state in which our products are sold
requires registration and payment of a fee. California and certain other states have adopted additional regulatory programs applicable
to these types of products that, in some cases, impose a fee on total product sales in the state.

Based
on our experience and our knowledge of current trends, we expect the costs and delays in receiving necessary federal and state approvals
for these types of products may increase in the coming years.

Requirements
Imposed by Ingredient Legislation

Numerous
federal, state and local laws regulate the sale of products containing certain identified ingredients that may impact human health and
the environment. For instance, California has enacted Proposition 65, which requires the disclosure of specified listed ingredient chemicals
on the labels of products. Although none of the ingredients in our current products are reportable under Proposition 65, this and other
similar legislation may become more comprehensive in the future and/or new products we may develop could be subject to these regulations.

10

Requirements
Imposed by Other Environmental Laws

A
number of federal, state and local environmental, health and safety laws govern the use, handling, storage and disposal of certain materials.
Our current manufacturing process for SDC-based products is a “zero waste” process, meaning that no byproducts are created,
and we do not use hazardous materials, as defined by applicable environmental laws, in the manufacturing of these products. As such,
some of these U.S. environmental laws are not generally applicable to us in their current form. However, these laws may in the future
identify, as hazardous materials certain materials that we use in our manufacturing processes, or we may opt to or be forced to change
our manufacturing procedures in a way that subjects our products or operations to these laws.

Requirements
Imposed by the U.S. FDA and USDA

Various
laws and regulations have been enacted by federal, state, local and foreign jurisdictions regulating certain products we manufacture
and sell for controlling microbial growth in or on foods. In the United States, these requirements generally are administered by the
FDA. However, the USDA and EPA also may share in regulatory jurisdiction of antimicrobials applied directly to food as it pertains to
poultry and meats.

Regulation
Outside the United States

The
commercialization of SDC-based products in countries other than the U.S. may require that we, or companies with whom we partner for such
foreign commercialization, obtain necessary approvals from foreign regulatory authorities comparable to the EPA, FDA and USDA, among
others. Applicable approval processes and ongoing requirements vary from country to country and may involve more time and expense than
that required to obtain approvals in the U.S. In international markets, we currently sell our products under active registrations held
by us, or by our distributors. We intend to continue to process registrations ourselves or through distributors as required.

We
currently hold a registration from Health Canada for our disinfectant product. We also have received a Letter of No Objection from Health
Canada for our antimicrobial food processing aid on fruits and vegetables intended for processing. Additionally, an opinion has been
granted under the Scientific Committee on Consumer Products to sell SDC in the European Union for use in cosmetics, which includes personal
care products.

Human
Capital

As
of October 29, 2026, we have 10 full-time employees and 1 part-time employee. We believe we have successfully attracted skilled and experienced
talent; however, the competition for qualified personnel is fierce, and we cannot guarantee our ability to retain or attract them in
the future. None of our employees are part of collective bargaining agreements, and we maintain positive relations with our team. We
are committed to fostering a culture that promotes the values, behaviors, and attributes essential for advancing our business and executing
our strategy.
