ORGANIZATION, NATURE OF BUSINESS, GOING CONCERN AND MANAGEMENT S PLANS: Organization and nature of business: Bion Environmental Technologies, Inc.'s ("Bion," "Company," "We," "Us," or "Our") was incorporated in 1987 one 2016 3rd “3G 3G May 2020 ( April 28, 2021.

Such credits can then be used as a ‘qualified offset' by an individual state (or municipality) to meet its federal clean water mandates at significantly lower cost to the taxpayer. Competitive procurement of verified credits is now supported by US EPA, the Chesapeake Bay Commission, national livestock interests, and other key stakeholders. Legislation in Pennsylvania to establish the first March 2019. 19 not The livestock industry is under tremendous pressure (from regulatory agencies, a wide range of advocacy groups, institutional investors and the industry's own consumers) to adopt sustainable practices.

May 3, 2021 3G The Company believes that organic approvals for its products: a) will provide access to substantially higher value markets compared to synthetic nitrogen products, and/or b) allow its products to be utilized in growing of organic feed grains to be consumed by livestock raised in JVs which will thereafter receive organic approvals. Based on preliminary market surveys to date: a) we believe that existing competing organic fertilizer products in both liquid and granular form are being sold presently at price points significantly greater than Bion's projected cost and projected pricing, and b) that livestock products (beef and pork) raised with feed grains grown using Bion organic ammonium carbonate fertilizer products (during the ‘finishing' stage) will qualify for organic approvals. It is anticipated that the Company will seek approvals for such products during the balance of the 2021 2021 3 Nutrient credits: Bion had believed that passage in Pennsylvania of legislation in 2019 19 2021 2022 SB575 twelve Note, however, that the current Covid- 19 not Bion's Kreider Farms poultry project (“Kreider 2” 1.5 3M $8 $12 21% 11M 2 may 2 $110B 4 Sustainable Branding: Consumers have demonstrated a willingness to pay a premium for their safe and sustainable food choices.

Bion's branding initiative reflects trends already underway in the livestock industry.

Bion believes that as these initiatives move forward, true sustainability on the production side will look a lot like what Bion can provide today with its 3G 3G The Covid- 19 Bion's ‘Environmental/Sustainable' branding program is designed to address a wide array of consumer concerns ranging from: a) ‘where does your food come from?', b) animal heritage information; c) anti-biotic use standards; d) humane animal treatment; d) its labor/human conditions (including hours, wages and working condition standards). It will include block chain traceability thereby enabling any quality issues to be quickly identified by lot and location thereby minimizing risk to its consumers.

The industry is structured to produce multiple levels of a commodity products (without any significant pricing premiums) graded based upon taste and tenderness. Today, however, consumer demand is shifting to products that are more sustainable, regarding carbon footprint, impacts to air and water and other metrics. The Company doesn't think the consumer wants to ‘blow up' the beef industry which is responsible for the best and safest beef available in the world today (as well as the livelihoods of almost 800,000 We are moving forward with preliminary pre-development work on a JV to build a state-of-the-art beef cattle operation in the Midwest U.S. The project would produce corn-fed USDA-certified organic- and/or sustainable-branded beef. Organic beef would be finished on organic corn (vs grass fed), produced using the ammonium bicarbonate fertilizer captured from the cattle's waste. We believe Bion's unique ability to produce fertilizer for growing of a supply of low-cost organic corn, and the resulting opportunity to produce organic beef, will dramatically differentiate us from potential competitors. This organic opportunity is dependent on successfully establishing Bion's fertilizer products as acceptable for use in organic grain production. In addition, as described above, we intend to develop JVs which use Bion's organic ammonium bicarbonate fertilizers to support organic grain production. This grain can be fed (in the finishing stage) to livestock and raise organic beef (and beef products) that will meet consumer demand with respect to sustainability and safety and provide the tenderness and taste American consumers have come to expect from premium American beef. Such a product is largely unavailable in the market today. Bion's current long-term goal is to acquire or develop, or have in a development pipeline, 2 5 24 48 A significant portion of Bion's activities concern efforts with private and public stakeholders (at local and state level) in Pennsylvania (and other Chesapeake Bay and Midwest and Great Lakes states) and at the federal level EPA and the Department of Agriculture (“USDA”) (and other executive departments) and Congress) to establish appropriate public policies which will create regulations and funding mechanisms that foster installation of the low cost environmental solutions that Bion (and others) can provide through clean-up of agricultural waste streams. The Company anticipates that such efforts will continue in Pennsylvania and other Chesapeake Bay watershed states throughout the next 12 Going concern and management s plans: The consolidated financial statements have been prepared assuming the Company will continue as a going concern.

Warrants are valued using a fair value based method, whereby the fair value of the warrant is determined at the warrant issue date using a market-based option valuation model based on factors including an evaluation of the Company's value as of the date of the issuance, consideration of the Company's limited liquid resources and business prospects, the market price of the Company's stock in its mostly inactive public market and the historical valuations and purchases of the Company's warrants. When warrants are issued in combination with debt or equity securities, the warrants are valued and accounted for based on the relative fair value of the warrants in relation to the total value assigned to the debt or equity securities and warrants combined. Concentrations of credit risk: The Company's financial instruments that are exposed to concentrations of credit risk consist of cash. The Company's cash is in demand deposit accounts placed with federally insured financial institutions and selected brokerage accounts. Such deposit accounts at times may not Noncontrolling interests: In accordance with ASC 810, Fair value measurements: Fair value is defined as 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 in the principal or most advantageous market. The Company uses a fair value hierarchy that has three Level 1 Level 2 1, not Level 3 Observable inputs are based on market data obtained from independent sources, while unobservable inputs are based on the Company's market assumptions. Unobservable inputs require significant management judgment or estimation. In some cases, the inputs used to measure an asset or liability may The fair value of cash and accounts payable approximates their carrying amounts due to their short-term maturities. The fair value of the loan payable is indeterminable at this time due to the nature of the arrangement with a state agency and the fact that it is in default. The fair value of the redeemable preferred stock approximates its carrying value due to the dividends accrued on the preferred stock which are reflected as part of the redemption value.
