NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

Note 1. Business and Organization

Description of Business 

BioLargo, Inc. is an innovative technology developer and environmental engineering company driven by a mission to "make life better" by delivering robust, sustainable solutions for a broad range of industries and applications, with a focus on clean water, clean air. The company also owns a minority interest in an advanced wound care subsidiary that has licensed BioLargo Technologies and it plans to spin out or sell when the appropriate opportunity is identified.  Our business strategy is straightforward: we invent or acquire technologies that we believe have the potential to be disruptive in large commercial markets; we develop and validate these technologies to advance and promote their commercial success as we leverage our considerable scientific, engineering, and entrepreneurial talent; we then monetize these technical assets through a variety of business structures that may include licensure, joint venture, sale, spin off, or by deploying direct to market strategies.

Liquidity / Going concern

For the nine months ended September 30, 2020, we had a net loss of $7,707,000, used $3,318,000 cash in operations, and at September 30, 2020, we had a working capital deficit of $1,316,000, and current assets of $1,873,000. We do not believe operating profits in the immediate future will be sufficient to fund our current level of operations. We have been, and anticipate that we will continue to be, limited in terms of our capital resources. None of our business segments (see Note 10, “Business Segment Information”) have ever generated enough revenues to fund their operations, or to contribute to our corporate operations or overhead. Thus, in light of our cash position at year end, in order to continue operations, in calendar year 2020 we have continued to sell our stock in private securities offerings and to Lincoln Park (see Note 3). Thus far this year, we have received approximately $1.7 million from Lincoln Park (an average of approximately $160,000 per month). The proceeds we receive from stock sales to Lincoln Park is a function of stock price and volume – a lower stock price and less trading volume results in less money we can receive from Lincoln Park. Although we have relied on investment funds through our agreement with Lincoln Park this year, there is no assurance that it will continue to provide the funds we need for our operations, and if it does not, we will have to rely on other forms of financing, and there is no assurance that we will be able to do so, or if we do so, it will be on favorable terms. We also regularly pay officers and vendors equity in lieu of cash, and anticipate that we will continue to be able to do so in the future. The foregoing factors raise substantial doubt about our ability to continue as a going concern, unless we are able to continue to raise funds through stock sales to Lincoln Park or other private financings, and in the long term, our ability to attain a reasonable threshold of operating efficiencies and achieve profitable operations by licensing or otherwise commercializing products incorporating our technologies. The consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

Organization

We are a Delaware corporation formed in 1991. We have four wholly-owned subsidiaries: BioLargo Life Technologies, Inc., organized under the laws of the State of California in 2006; ONM Environmental, Inc. (formerly, Odor-No-More, Inc.), organized under the laws of the State of California in 2009; BioLargo Water Investment Group Inc. organized under the laws of the State of California in 2019, which wholly owns BioLargo Water, Inc., organized under the laws of Canada in 2014; and BioLargo Development Corp., organized under the laws of the State of California in 2016. Additionally, we own 97.5% (see Note 9) of BioLargo Engineering Science and Technologies, LLC (“BLEST”), organized under the laws of the State of Tennessee in 2017. We also own 47% of Clyra Medical Technologies, Inc. (“Clyra Medical”), organized under the laws of the State of California in 2012, and consolidate their financial statements (see Note 2, subheading “Principles of Consolidation,” and Note 8).

The unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to Rule 8-03 of Regulation S-X under the Securities Act of 1933, as amended. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for annual financial statements.  In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. We are still operating in the early stages of the sales and distribution process, and therefore our operating results for the three and nine months ended September 30, 2020, are not necessarily indicative of the results that may be expected for the year ending December 31, 2020, or for any other period. These unaudited consolidated financial statements and notes should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2020.

Note 2. Summary of Significant Accounting Policies

In the opinion of management, the accompanying balance sheet and related statements of operations, cash flows, and stockholders’ deficit include all adjustments, consisting only of normal recurring items, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, and its wholly- and partially-owned subsidiaries, including Clyra Medical. Management believes Clyra Medical’s financial statements are appropriately consolidated with that of the Company after reviewing the guidance of ASC Topic 810, “Consolidation”, and concluding that BioLargo controls Clyra Medical. While BioLargo does not have voting interest control through a majority stock ownership of Clyra Medical (it owns 47% of the outstanding voting stock), it does exercise control under the “Variable Interest Model”: there is substantial board overlap, BioLargo is the primary beneficiary since it has the power to direct Clyra Medical’s activities that most significantly impact Clyra Medical’s performance, and it has the obligation to absorb losses or receive benefits (through royalties and licensing) that could be potentially significant to Clyra Medical. BioLargo has consolidated Clyra Medical’s operations for all periods presented. (See Note 8.)

All intercompany accounts and transactions have been eliminated. 

Foreign Currency

The Company has designated the functional currency of BioLargo Water, Inc., our Canadian subsidiary, to be the Canadian dollar. Therefore, translation gains and losses resulting from differences in exchange rates are recorded in accumulated other comprehensive income.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three-months or less when acquired to be cash equivalents. Substantially all cash equivalents are held in short-term money market accounts at one of the largest financial institutions in the United States. From time to time, our cash account balances are greater than the Federal Deposit Insurance Corporation insurance limit of $250,000 per owner per bank, and during such times, we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the financial institution. We do not anticipate non-performance by our financial institution.

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts as of December 31, 2019 was $24,000 and September 30, 2020 was $35,000.

Credit Concentration

We have a limited number of customers that account for significant portions of our revenue. For the nine months ended September 30, 2019 and 2020, each period had two customers that accounted for 10% or more of our consolidated revenues, as follows:

	September 30, 2019			September 30, 2020
Customer A	<10		%		12	%
Customer B		13	%	<10		%
Customer C		10	%	<10		%

We had two customers that accounted for more than 10% of consolidated accounts receivable at December 31, 2019 and three customers that accounted for more than 10% of consolidated accounts receivable at September 30, 2020, as follows:

	December 31, 2019			September 30, 2020
Customer A	<20		%		15	%
Customer D	<10		%		15	%
Customer E	<10		%		10	%
Customer F		14	%	<10		%
Customer G		13	%	<10		%

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. The allowance for obsolete inventory as of December 31, 2019 and September 30, 2020 was $3,000. As of December 31, 2019, and September 30, 2020, inventories consisted of (in thousands):

	December 31, 2019		September 30, 2020
Raw material	$	11	$	180
Finished goods		5		112
Total	$	16	$	292

Other Non-Current Assets

Other non-current assets consisted of (i) security deposits of $35,000 related to our business offices, and (ii) prepaid consulting fees from the issuance of Clyra Medical stock, resulting in a fair value of $787,500 (see Note 8).

Leases

In February 2016, the FASB issued ASU Update No. 2016-02, “Leases,” which requires lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability, and lessors to recognize a net lease investment. Additional qualitative and quantitative disclosures are also required. We adopted this standard effective January 1, 2019 using the effective date option, which resulted in a $399,000 gross up of assets and liabilities; this balance may fluctuate over time as we enter into new leases, extend or terminate current leases. Upon the transition to the ASC 842, the Company elected to use hindsight as a practical expedient with respect to determining the lease terms (as we considered our updated expectations of acceptance of the Westminster California facility lease renewal) and in assessing any impairment of right-of-use assets for existing leases. No impairment is expected at this time. As of September 30, 2020, the right-of-use assets on our balance sheet related to our operating leases totals $356,000.

Impairment

Long-lived and definite lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected future undiscounted cash flows from the use of the asset and its eventual disposition is less than the carrying amount of the asset, then an impairment loss is recognized. The impairment loss is measured based on the fair value of the asset. Any resulting impairment is recorded as a reduction in the carrying value of the related asset in excess of fair value and a charge to operating results. As of September 30, 2019 and 2020, management determined that there was no impairment of its long-lived assets, including its In-process Research and Development at Clyra Medical (see Note 8).

Equity Method of Accounting

On March 20, 2020, we invested $100,000 into a South Korean entity (Odin Co. Ltd., “Odin”) pursuant to a Joint Venture agreement we had entered into with BKT Co. Ltd. and its U.S. based subsidiary, Tomorrow Water. We received a 40% non-dilutive equity interest, and BKT and Tomorrow Water each received 30% equity interests for an aggregate $150,000 investment.

BIOLARGO, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

We account for our investment in the joint venture under the equity method of accounting. We have determined that while we have significant influence over the joint venture through our technology license and our position on the Board of Directors, we do not control the joint venture or are otherwise involved in managing the entity and we own less than a majority of the equity. Therefore, we record the asset on our consolidated balance sheet and record an increase or decrease the recorded balance by our percentage ownership of the profits or losses in the joint venture. During the nine months ended September 30, 2020, the joint venture incurred a loss and our 40% ownership share reduced our investment interest by $27,000.

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the three and nine months ended September 30, 2019 and 2020, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, debt transactions, derivative liabilities, allowance for bad debt, asset depreciation and amortization, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-Based Compensation Expense

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Fair value is determined on the grant date. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model.

For stock and stock options issued to consultants and other non-employees for services, the Company measures and records an expense as of the earlier of the date at which either: a commitment for performance by the non-employee has been reached or the non-employee’s performance is complete. The equity instruments are measured at the current fair value, and for stock options, the instruments are measured at fair value using the Black Scholes option model.

The following methodology and assumptions were used to calculate share-based compensation for the three and nine months ended September 30, 2019 and 2020:

	2019						2020
	Non Plan			2018 Plan			Non Plan			2018 Plan
Risk free interest rate	2.00	–	2.65%	2.0	–	2.65%	0.66	–	1.02%	0.64	–	1.90%
Expected volatility	147	–	152%	147	–	152%	129	–	131%	126	–	133%
Expected dividend yield		—			—			—			—
Forfeiture rate		—			—			—			—
Life in years		10			10			10			10

Expected price volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Expected volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility.

The risk-free interest rate used in the Black-Scholes calculation is based on the prevailing U.S. Treasury yield as determined by the U.S. Federal Reserve. We have never paid any cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future.

Historically, we have not had significant forfeitures of unvested stock options granted to employees and Directors. A significant number of our stock option grants are fully vested at issuance or have short vesting provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock options as zero.

Warrants

Warrants issued with our convertible promissory notes, note payables, and lines of credit, are accounted for under the fair value and relative fair value method. The warrant is first analyzed per its terms as to whether it has derivative features or not. If the warrant is determined to be a derivative and not qualify for equity treatment, then it is measured at fair value using the Black Scholes option model, and recorded as a liability on the balance sheet. The warrant is re-measured at its then current fair value at each subsequent reporting date (it is “marked-to-market”). If the warrant is determined to not have derivative features, it is recorded into equity at its fair value using the Black Scholes option model, however, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the convertible note.

The convertible note issued with the warrant is recorded at its fair value, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the warrant. Further, the convertible promissory note is examined for any intrinsic beneficial conversion feature (“BCF”) of which the convertible price of the note is less than the closing common stock price on date of issuance. If the relative fair value method is used to value the convertible promissory note and there is an intrinsic BCF, a further analysis is undertaken of the BCF using an effective conversion price which assumes the conversion price is the relative fair value divided by the number of shares the convertible debt is converted into by its terms. The BCF value is accounted for as equity.

The warrant and BCF relative fair values are also recorded as a discount to the convertible promissory notes.

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue Recognition

We account for revenue in accordance with ASC 606, “revenue from Contacts with Customers”. The guidance focuses on the core principle for revenue recognition, which is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, the guidance provides that an entity should apply the following steps:

Step 1: Identify the contract(s) with a customer.

Step 2: Identify the performance obligations in the contract.

Step 3: Determine the transaction price.

Step 4: Allocate the transaction price to the performance obligations in the contract.

Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

We have revenue from four subsidiaries, ONM, BLEST, BioLargo Water, and Clyra. ONM, BioLargo Water, and Clyra identify its contract with the customer through a written purchase order, in which the details of the contract are defined including the transaction price and method of shipment. The only performance obligation is to create and ship the product and each product has separate pricing. Revenue is recognized at a point in time when the order for its goods are shipped if its agreement with the customer is FOB manufacturer, and when goods are delivered to its customer if its agreement with the customer is FOB destination. Revenue is recognized with a reduction for sales discounts, as appropriate and negotiated in the customer’s purchase order. ONM also installs misting systems for which it bills on a time and materials basis. It identifies its contract with the customer through a written purchase order in which the details of the time to be billed and materials purchased and an estimated completion date. The performance obligation is the completion of the installation. Revenue is recognized over time as the work is performed.

BLEST identifies services to be performed in a written contract, which specifies the performance obligations and the rate at which the services will be billed. Each service is separately negotiated and priced. Revenue is recognized as services are performed and completed. BLEST’s contracts typically call for invoicing for time and materials incurred for that contract. A few contracts have called for milestone or fixed cost payments, where BLEST invoices an agreed-to amount per month for the life of the contract. In these instances, completed work, billed hourly, is recognized as revenue. If the billing amount is greater or lesser than the completed work, a receivable or payable is created. These accounts are adjusted upon additional billings as the work is completed. To date, there have been no discounts or other financing terms for the contracts.

In the event that we generate revenues from royalties or license fees from our intellectual property, we anticipate a licensee would pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. Upon entering into a licensing agreement, we will determine the appropriate method of recognizing the royalty and license fees.

Government Grants

We have been awarded multiple research grants from governmental and quasi-governmental institutions. The grants received are considered “other income” and are included in our Consolidated Statements of Operations. We received our first grant in 2015 and have been awarded over 80 grants totaling over $3.7 million. Some of the funds from these grants are given directly to third parties (such as the University of Alberta or a third-party research scientist) to support research on our technology. The grants have terms generally ranging between nine and eighteen months and support a majority, but not all, of the related research budget costs. This cooperative research allows us to utilize (i) a depth of resources and talent to accomplish highly skilled work, (ii) financial aid to support research and development costs, (iii) independent and credible validation of our technical claims.

The grants typically provide for (i) recurring monthly amounts, (ii) reimbursement of costs for research talent for which we invoice to request payment, and (iii) ancillary cost reimbursement for research talent travel related costs. All awarded grants have specific requirements on how the money is spent, typically to employ researchers. None of the funds may be used for general administrative expenses or overhead in the United States. These grants have substantially increased our level of research and development activities in Canada. We continue to apply for Canadian government and agency grants to fund research and development activities. There was no grant income for the three months ended September 30, 2020. Not all of our grant applications have been awarded, and no assurance can be made that any pending grant application, or any future grant applications, will be awarded.

Fair Value of Financial Instruments

Management believes the carrying amounts of the Company’s financial instruments (excluding debt and equity instruments) as of December 31, 2019, and September 30, 2020, approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, lines of credit, and other assets and liabilities.

Note 3. Equity Financing

Lincoln Park

During the three months ended March 31, 2020, pursuant to our August 2017 agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”), we elected to sell to Lincoln Park 1,398,223 shares of our common stock, for which we received $295,000 in gross and net proceeds. Additionally, we issued Lincoln Park 14,420 “additional commitment” shares required under the agreement. We did not sell any shares to Lincoln Park during the three and nine months ended September 30, 2019. In conjunction with the signing of the March 2020 agreement with Lincoln Park (see below), we recorded the remaining deferred offering costs on our August 2017 agreement totaling $122,000 as additional paid in capital on our consolidated balance sheet.

On March 30,^, 2020, we entered into a Purchase Agreement with Lincoln Park, pursuant to which Lincoln Park agreed to purchase from us at our request up to an aggregate of $10,250,000 of our common stock (subject to certain limitations) from time to time over a period of three years. The agreement allows us, at our sole discretion, to direct Lincoln Park to purchase shares of our common stock, subject to limitations in both volume and dollar amount. The purchase price of the shares that may be sold to Lincoln Park under the Purchase Agreement is the lower of (i) the lowest sale price on the date of purchase, or (ii) the average of the three lowest closing prices in the prior 12 business days. There are no restrictions on future financings, rights of first refusal, participation rights, penalties or liquidated damages other than a prohibition on entering into a “Variable Rate Transaction,” as defined in the agreement. Lincoln Park may not assign or transfer its rights and obligations under the Purchase Agreement. This agreement replaced the August 2017 agreement with Lincoln Park. Concurrently with the Purchase Agreement, we entered into a Registration Rights Agreement, pursuant to which we filed a registration statement on Form S-1 with the SEC on April 10, 2020. This registration statement was declared effective on April 21, 2020, and as of April 29, 2020, we commenced regular purchases under the agreement.

In the March 30, 2020 agreement, we agreed to issue 2,928,571 shares to Lincoln Park as a commitment fee, valued at $527,000 and recorded as additional paid in capital on our consolidated balance sheet as of March 31, 2020. Additionally, the Purchase Agreement provided for an initial sale of 1,785,715 shares to Lincoln Park for $250,000. We received those funds and issued the shares on March 31, 2020.

Since inception of the March 30, 2020 agreement through September 30, 2020, not including the initial purchase, we sold 6,508,675 shares to Lincoln Park for $1,043,000. For the three months ended September 30, 2020, we sold 4,893,981 shares to Lincoln Park for $797,000.

2020 Unit Offering

On May 1, 2020, we commenced a private offering of units, each unit consisting of (i) common stock, (ii) a four-month stock purchase warrant, and (iii) a five-year stock purchase warrant. Unit prices are set from time-to-time based on market conditions. The number of shares of common stock issued, and the number of shares available for purchase under each warrant, are based on the quotient of the unit price and investment amount (e.g., a $100,000 investment and unit price of $0.25 is equal to 400,000 shares). The four-month warrant exercise price is equal to 120% of the unit price, and the five-year warrant is equal to 150% of the unit price.

During the nine months ended September 30, 2020, we received an aggregate $367,000 of investments from five investors at unit prices ranging between $0.15 and $0.18, issued 2,318,194 shares of our common stock, and issued six-month and five-year warrants (see Note 6).

For the nine months ended September 30, 2019 and 2020, we recorded $2,773,000 and $1,823,000 of interest expense related to the amortization of discounts on convertible notes payable, and coupon interest from our convertible notes and line of credit.

The following discussion includes debt instruments to which amendments were made or included other activity that management deemed appropriate to disclose. Each of the debt instruments contained in the above table are disclosed more fully in the financial statements contained in the Company’s Annual Report filed March 31, 2020.

SBA Program Loans

In April 2020, our subsidiaries ONM, BLEST and Clyra received $218,000, $96,000 and $43,000, respectively, received loans pursuant to the U.S. Small Business Administration Paycheck Protection Program. The loans mature in two years and incur interest at 1%. Management believes that it has fully complied with the terms of forgiveness as set forth by the Small Business Administration, and intends to apply for forgiveness of 100% of this debt at the appropriate time.

Our subsidiary ONM received an Economic Injury Disaster loan from the U.S. Small Business Administration of $150,000. The term of the loan is 30 years and has a 3.75% interest rate. Monthly payments of $800 begin July 2021.

Convertible Note, matured April 7, 2020 (Vista Capital)

On January 7, 2019, Vista Capital Investments LLC (“Vista Capital”) invested $300,000 and in exchange we issued a convertible promissory note in the principal amount of $330,000. Originally set to mature nine months from the date of issuance, the maturity date was extended multiple times. The note earned a one-time interest charge of 12%, which was recorded as a discount on convertible notes and was amortized over the term of the note. The note allowed conversion of the note into our common stock at a price equal to 65% of the lowest closing bid price of the Company’s common stock during the 25 consecutive trading days immediately preceding the conversion date. The intrinsic value of the beneficial conversion feature resulted in a fair value totaling $300,000, and is recorded as a discount on convertible notes on our balance sheet. This discount was amortized over the term of the note as interest expense, all of which was recorded in 2019.

During the three months ended March 31, 2020, Vista Capital elected to convert the remaining balance of $270,000 of the outstanding principal and interest due on the note, and we issued 2,417,059 shares of our common stock.

Convertible Twelve-month OID notes

From June 7, 2019 through September 30, 2019, we received $2,235,000 and issued convertible promissory notes (each, a “Twelve-Month OID Note”) in the aggregate principal amount of $2,794,000, with a 25% original issue discount, to 34 accredited investors. The original issuance discount totaled $559,000 and is recorded as a discount on convertible notes payable on our balance sheet. The intrinsic value of the beneficial conversion features resulted in an aggregate fair value of $2,235,000, and is recorded as a discount on convertible notes on our balance sheet. The discounts were amortized and recorded to interest expense over the term of the notes. These notes each mature twelve months from the date of issuance.

During the three months ended September 30, 2019, in exchange for $305,000 of convertible note payables that were coming due, we issued an additional $381,000 in Twelve-Month OID Notes, with a 25% original issue discount. The original issue discount totaled $76,000 and is recorded as a discount on convertible notes payable on our balance sheet. The intrinsic value of the beneficial conversion features resulted in an aggregate fair value of $381,000 and is recorded as debt extinguishment expense on our statement of operations. The discount will be amortized and recorded to interest expense over the term of the notes. These notes mature twelve months from the date of issuance.  

Each Twelve-month OID Note is convertible by the investor at any time at $0.17 per share. The notes earn interest at a rate of five percent (5%) per annum, due at maturity. At the maturity of each note, the Company exercised its right to redeem the notes through the issuance of common stock at a conversion price equal to the lower of the “conversion price” (initially $0.17, as may be adjusted), and 70% of the lowest daily volume weighted average price of the Company’s common stock during the 25 trading days preceding the conversion date. During the nine months ended September 30, 2020, $3,112,000 of the remaining outstanding principal of 12-Month OID Notes was converted, and we issued 30,208,453 shares of our common stock. Of that amount, 1,415,221 shares were issued as payment for interest due on the notes.

Note Maturity Extensions

On August 10, 2020, we and the holder of a convertible promissory note in the principal amount of $475,000 due August 12, 2020, entered into an agreement to extend the maturity date of the note to August 12, 2021. As consideration for the extension of the maturity date, we agreed to lower the conversion price from $0.17 to $0.14, we agreed extend the expiration date from September 18, 2023 to September 18, 2025, of a warrant to purchase 1,734,375 shares of common stock, and extend the expiration date from August 12, 2024 to August 12, 2025 of a warrant to purchase 2,095,588 shares of common stock. The fair value of the reduced conversion price and extended warrant expirations dates resulted in a fair value totaling $228,000, recorded as a loss on extinguishment on our statement of operations. The noteholder then converted $119,000 of principal into 848,214 shares of common stock and $24,000 of accrued interest into 169,643 shares of common stock. The outstanding balance of this note as of September 30, 2020 was $356,000.

On August 10, 2020, we and the holder of a convertible promissory note in the principal amount of $75,000 due August 20, 2020, entered into an agreement in which we agreed to pay $25,000, and the holder agreed to extend the maturity date of the note to August 20, 2021.

2018 Equity Incentive Plan

On June 22, 2018, our stockholders adopted the BioLargo 2018 Equity Incentive Plan (“2018 Plan”) as a means of providing our directors, key employees and consultants additional incentive to provide services. Both stock options and stock grants may be made under this plan for a period of 10 years. Our Board of Director’s Compensation Committee administers this plan.

The plan authorizes the following types of awards: (i) incentive and non-qualified stock options, (ii) restricted stock awards, (iii) stock bonus awards, (iv) stock appreciation rights, (v) restricted stock units, and (vi) performance awards. The total number of shares reserved and available for awards pursuant to this Plan as of the date of adoption of this 2018 Plan by the Board is 40 million shares. The number of shares available to be issued under the 2018 Plan increases automatically each January 1^st by the lesser of (a) 2 million shares, or (b) such number of shares determined by our Board.

Warrants issued in private offering

During the three months ended September 30, 2020, pursuant to our 2020 Unit Offering (see Note 3), we issued six-month stock purchase warrants to purchase an aggregate 746,528 shares of our common stock at prices from $0.192 to $0.216 per share, and five-year stock purchase warrants to purchase an aggregate 746,528 shares of our common stock at prices from $0.24 to $0.27 per share. During the nine months ended September 30, 2020, we issued six-month stock purchase warrants to purchase an aggregate 2,318,194 shares of our common stock at prices from $0.18 to $0.22 per share, and five-year stock purchase warrants to purchase an aggregate 2,318,194 shares of our common stock at prices from $0.225 to $0.27 per share.

Fair Value – Interest Expense

To determine interest expense related to our outstanding warrants issued in conjunction with debt offerings, the fair value of each award grant is estimated on the date of grant using the Black-Scholes option pricing model and the relative fair values are amortized over the life of the warrant. For the determination of expense of warrants issued for services, extinguishment of debt and settlement management also uses the option-pricing model. The principal assumptions we used in applying this model were as follows:

Note 8. Noncontrolling Interest – Clyra Medical

Acquisition of In-process Research and Development

On September 26, 2018, Clyra Medical entered into a transaction with Scion Solutions, LLC, for the purchase of its intellectual property, including its SkinDisc. The consideration provided to Scion is subject to an escrow agreement (“Escrow Agreement”) and earn out provisions and includes: (i) 21,000 shares of the Clyra Medical common stock; (ii) 10,000 shares of Clyra Medical common stock redeemable for 7,142,858 BioLargo common shares held by Clyra Medical; and (iii) a promissory note in the principal amount of $1,250,000 to be paid through new capital investments and revenue, as detailed below. This consideration was initially held in escrow pending Clyra Medical raising $1 million “base capital” to fund its business operations.

On December 17, 2018, the parties entered into a closing agreement (“Closing Agreement”) reflecting the satisfaction of the obligation to raise $1 million “base capital”; at that time, one-half of the shares of Clyra Medical common stock exchanged for the Scion assets were released to Scion. The remaining Clyra Medical common shares (a total of 15,500 shares) remain subject to the Escrow Agreement’s performance metrics, each vesting one-fifth of the remaining shares of common stock (e.g., 2,000 shares of Clyra common stock, and an additional 1,100 shares redeemable for 785,714 BioLargo shares): (a) notification of FDA premarket clearance of certain orthopedics products, or recognition by Clyra Medical of $100,000 gross revenue; (b) the recognition by Clyra Medical of $100,000 in aggregate gross revenue; (c) the granting of all or any part of the patent application for the SkinDisc product, or recognition by Clyra Medical of $500,000 in gross revenue; (d) recognition by Clyra Medical of $1 million in aggregate gross revenue; and (e) recognition by Clyra Medical of $2 million in gross revenue.

During the three months ended September 30, 2020, Clyra gross revenue exceeded $100,000, and thus the first performance metric was met. As a result, Scion vested 3,100 common shares. The fair value of the shares vested total $128,000 and was recorded on our balance sheet as In-Process Research and Development, and Liability to Clyra Medical Shareholder.

Scion Solutions – Note Payable and Clyra Liability

The promissory note in the principal amount of $1,250,000 issued by Clyra Medical to Scion on September 26, 2018 (“Clyra-Scion Note”) accrues interest at the rate of 5%. Principal and interest due under the note are to be paid periodically at a rate of 25% of investment proceeds received by Clyra Medical. At the initial maturity of June 17, 2020, the maturity date of the note automatically extended for 12 months and will continue to automatically extend for additional 12-month periods until the note is repaid in full. Clyra is required to make annual payments on the note in an amount equal to the greater of (i) 25% of investment proceeds received during the 12-month period, and (ii) 5% of Clyra Medical’s gross revenues.

At September 30, 2020, the balance due on the Clyra-Scion Note equaled $1,007,000. The shares of BioLargo common stock held by Clyra for the benefit of Scion (the redemption shares) totals $771,000 and is recorded on our balance sheet as a liability to “Clyra Medical Shareholder”.

Inventory Line of Credit

On June 30, 2020, Clyra entered into a Revolving Line of Credit Agreement whereby Vernal Bay Capital Group, LLC committed to provide a $1,000,000 inventory line of credit to Clyra, with a first draw of $200,000 received July 6, 2020. Clyra is required to use funds from the line of credit to manufacture inventory. Additional draws are conditional upon Clyra presenting invoices or purchase orders to the lender equal to the greater of one-half of principal outstanding on the line of credit, and $200,000.

The line of credit note earns interest at 15%, matures in one year, and requires Clyra pay interest and principal from gross product sales. For the first 180 days, on a monthly basis, Clyra is required to pay 30% of gross product sales to reduce amounts owed, and thereafter 60% of gross sales. Clyra issued Vernal Bay 323 shares of its common stock as a commitment fee for the line of credit, valued at $100,000. A security agreement of the same date grants Vernal Bay a security interest in Clyra’s inventory, as that term is defined in the Uniform Commercial Code. Clyra may prepay the note at any time.

Clyra has received a second draw under this line of credit (see Note 12).

Clyra Financing

During the nine months ended September 30, 2020, Clyra sold 2,742 shares of its common stock at $310 per Clyra share.

During June 2020, BioLargo increased its investment in Clyra by 23,004 shares. Of this amount, 22,513 shares were issued to BioLargo pursuant to an amendment to the BioLargo/Clyra license agreement whereby BioLargo has granted Clyra rights to commercialize its technology in certain medical fields. The amendment provided, among other things, for the payment of the “initial license fee” through the issuance of 22,513 shares of Clyra common stock. (See Note 2.)

As of September 30, 2020, Clyra Medical had the following common (and no preferred) shares outstanding:

Shareholder	Shares	Percent
BioLargo, Inc.	49,207	47%
Sanatio Capital	18,704	18%
Scion Solutions(1)	18,600	17%

(UNAUDITED)

During 2019, Clyra began issuing options to its employees and consultants in lieu of compensation owed. As of December 31, 2019, the Company had issued options to purchase 7,624 shares of Clyra stock. In the three and nine months ended September 30, 2020, Clyra issued options to purchase 645 and 2,685 shares of Clyra Medical common stock. Each option issued has an exercise price of $1.00 per share, are vested upon issuance and an expiration date 10 years from the date of grant. The fair value of the options issued in the three and nine months ended September 30, 2020, totaled $140,000 and $580,000, respectively, and the additional fair value totaling $214,000 was recorded as a loss on extinguishment of debt in our consolidated statement of operations. We used the Black-Scholes model to calculate the initial fair value, assuming a stock price on date of grant of $310 per share. Because Clyra is a private company with no secondary market for its common stock, the resulting fair value was discounted by 30%.

Consulting Agreement

Clyra entered into a consulting agreement with Beach House Consulting, LLC, through which Jack B. Strommen will be providing consulting services to Clyra related to its sales and marketing activities, and in exchange receive $23,000 per month for a period of four years. On June 30, 2020, at Clyra’s request, Beach House Consulting agreed to accept 3,639 shares of Clyra common stock as full payment of the consulting fee, in lieu of cash. The obligation to provide the consulting services is dependent on Clyra generating an average of $250,000 in monthly sales over three consecutive months. The value of the shares issued to Beach House is recorded as a prepaid asset (see Note 2).

Note 9. BioLargo Engineering, Science and Technologies, LLC

In September 2017, we commenced a full-service environmental engineering firm and formed a Tennessee entity named BioLargo Engineering, Science & Technologies, LLC (“BLEST”). In conjunction with the start of this subsidiary, we entered into a three-year office lease in the Knoxville, Tennessee area (since extended), and entered into employment agreements with six scientists and engineers. The company was capitalized with two classes of membership units: Class A, 100% owned by Biolargo, and Class B, held by management of BLEST, and which initially had no “profit interest,” as that term is defined in Tennessee law. However, over the succeeding five years, the Class B members can earn up to a 30% profit interest. They were also granted options to purchase up to an aggregate 1,750,000 shares of BioLargo, Inc. common stock. The profit interest and option shares are subject to a five year vesting schedule tied to the performance of the subsidiary, including gross revenue targets that increase over time, obtaining positive cash flow by March 31, 2018 (which was not met), collecting 90% of its account receivables, obtaining a profit of 10% in its first year (and increasing in subsequent years), making progress in the scale-up and commercialization of our AOS system, and using BioLargo research scientists (such as our Canadian team) for billable work on client projects. These criteria are to be evaluated annually by BLEST’s compensation committee (which includes BioLargo’s president, CFO, and BLEST’s president), beginning September 2018. Given the significant performance criteria, the Class B units and the stock options will only be recognized in compensation expense if or when the criteria are satisfied.

Since the commencement of operations, the Compensation Committee has met twice, once in September 2018, and once in November 2019. In 2018, it reviewed the operating performance and determined that the performance metrics were not met and as a result, did not award any Class B units or stock options. The Committee decided to roll forward one additional year to the time allowed for the performance metrics to be met and for the Class B units and stock options to be awarded.

In November 2019, the Compensation Committee again reviewed the operating performance and determined that a portion of the performance metrics were met. It was agreed that one-half of the eligible profits interests would be vested (2.5% in the aggregate). The fair value of the profit interest was nominal and not recorded. Nevertheless, Biolargo treats the 2.5% profits interest as part of the noncontrolling interest on both the balance sheet and the statement of operations.

Note 10. Business Segment Information

BioLargo currently has four operating business segments, plus its corporate entity which is responsible for general corporate operations, including administrative functions, finance, human resources, marketing, legal, etc. The four operational business segments are:

1. ONM Environmental (formerly Odor-No-More) (“ONM”) -- which sells odor and volatile organic control products and services (located in Westminster, California);

2. Clyra Medical Technologies (“Clyra Medical”) -- which develops and sells medical products based on our technologies, including Clyraguard Personal Protective Spray;

3. BLEST -- which provides professional engineering services on a time and materials basis for outside clients and supports our internal operations as needed (located in Oak Ridge, Tennessee); and

4. BioLargo Water (“Water”) -- which historically focused entirely on R&D, and has now shifted its focus to commercializing the AOS technology, developing manufacturing operations for hand sanitizers and supporting the development of iodine based disinfecting products for the company (located in Edmonton, Alberta Canada).

Historically, none of our operating business units have operated at a profit and therefore each required additional cash to meet its monthly expenses. The additional sources of the cash to fund the shortfall from operations of ONM, BLEST and BioLargo Water have been provided by BioLargo’s sales of debt or equity, research grants, and tax credits. Clyra Medical has been funded by third party investors who invest directly in Clyra Medical in exchange for equity ownership in that entity.

The segment information for the three and nine months ended September 30, 2019 and 2020, is as follows (in thousands):

BIOLARGO, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

Note 11. Commitments and Contingencies

COVID-19

On March 11, 2020, the World Health Organization declared the outbreak of Coronavirus Disease 2019 (“COVID-19” or “virus”) as a global pandemic. The full impact of COVID-19 is unknown and rapidly evolving. The outbreak and any preventative or protective actions that the Company or its customers may take in respect of this virus may result in a period of disruption, including the Company’s financial reporting capabilities or its operations generally, and could potentially impact the Company’s customers and other third parties. Any resulting financial impact cannot be reasonably estimated at this time, but may materially affect the business and the Company’s financial condition and results of operations. The extent to which the COVID-19 impacts the Company’s results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions to contain the virus or treat its impact, among others. The Company has been operating remotely without any significant disruption of operations, although its clients have been disrupted. The Company is currently evaluating the impact, if any, on its financial statements, and has not yet quantified what material impacts to the financial statements may result from the actions taken by the Company and its customers in respect of this virus.

Office Leases

We have long-term operating leases for office, industrial and laboratory space in Westminster, California, Oak Ridge, Tennessee, and Alberta, Canada. Payments made under operating leases are charged to the Consolidated Statement of Operations and Comprehensive Loss on a straight-line basis over the term of the operating lease agreement. For the nine months ended September 30, 2019 and 2020, rental expense was $156,000 and $167,000, respectively.  On January 1, 2019, we adopted ASC 842 which resulted in a right-of-use asset and lease liability. Short-term leases are not included in our analysis. The adoption resulted in an immaterial cumulative effect of an accounting change that was not recorded.  The lease of our Westminster facility qualifies for the new treatment; it originated in August 2016, was originally scheduled to expire August 2020, contains a yearly escalation of 3%, and includes a four-year renewal option whereby the base rent is adjusted to then market value. We exercised our option to extend the lease for four years. It is too early for management to determine if it will extend another four years, therefore the additional four-year extension is not included in the analysis. The lease of our Oak Ridge, Tennessee facility also qualifies, and it had one executed extension to September 2022, and has one renewal option for another five years where the rental rate would adjust to greater of the current price and fair market value. No determination has been made whether to exercise the renewal option for the Oak Ridge facility. The lease of our Canadian facility is less than one year. None of our leases have additional terms related to the payments or mechanics of the lease: there are not any common area maintenance charges or tax sharing arrangements, easement provisions or any free rent. Since there is no explicit interest rate in leases, management used its incremental borrowing rate, which is estimated to be 18%. As of September 30, 2020, our weighted average remaining lease term is three years and the total remaining operating lease payments is $578,000.

Note 12. Subsequent Events.

Management has evaluated subsequent events through the date of the filing of this Quarterly Report and management noted the following for disclosure.

Sales of Stock to Lincoln Park

From October 1, 2020, through November 11, 2020, we sold 943,667 shares of our common stock to Lincoln Park (see Note 3) and received $135,000 in gross and net proceeds. These sales were registered with the SEC on Form S-1, Registration Number 333-237651.

Inventory Line of Credit (Clyra Medical)

Subsequent to September 30, 2020, Clyra received a draw of $60,000 on its inventory line of credit (see Note 8).

Development of AEC to Combat PFAS Crisis

Our engineers at BLEST have developed a novel water treatment system, called the AEC (Aqueous Electrostatic Concentrator) , that removes per- and polyfluoroalkyl substances (PFAS) from water at a fraction of the cost of existing carbon-based and reverse osmosis solutions, which are the dominant incumbent solutions. PFAS chemicals can cause cancer, infertility, asthma, and other health problems in human beings, are present in a vast range of manufactured goods, common household products (e.g., cleaning products, cookware), and electronics, and contaminate drinking water in unsafe levels all over the globe. Governments and industry are actively seeking less expensive technologies and processes to eliminate PFAS from groundwater and drinking water, and the U.S. EPA has made finding an economical solution a priority.

The AEC has been proven in lab-scale studies to meet or exceed the performance of carbon-filtration and reverse osmosis systems while consuming as little as $0.30 in electrical costs per 1,000 gallons treated. The design of the AEC results in substantially less waste produced than carbon-filtration and reverse osmosis systems, with the AEC’s specialized membranes (onto which the PFAS molecules adhere), creating far less of a disposal liability than incumbent technologies. We believe testing will show that total operating costs of the AEC represent a significant potential cost savings compared to incumbent PFAS solutions like reverse osmosis and carbon sequestration technologies. Thus far in 2020, Orange County, California, has taken more than 40 drinking water wells out of service due to PFAS contamination, and estimate treatment systems using existing technology will cost more than $200 million to build and more than $400 million to operate and maintain. We believe the AEC system could reduce those costs significantly.

Recently, our engineers completed the design for a modular AEC unit and are now gathering testing data at the request of a municipal water agency. We intend to field test an AEC unit in conjunction with the AOS project in Montreal (see Wastewater Treatment Pilot – Montreal, below). Additionally, multiple U.S. municipal water agencies have expressed interest in the technology, and indicate they would be available to test a pilot-scale unit. We are hopeful that these pre-commercial trials can begin in early 2021. During this process, our engineers will continue to refine the design of the AEC and ready it for a commercial launch. Those same municipal agencies have told BioLargo management that they have a significant need for economically feasible PFAS treatment solutions, and that existing solutions do not adequately fulfill this need.

Broadly speaking, there are three main markets for PFAS water treatment in the U.S., all of which BLEST may address in the coming years. The first is municipal water treatment – that is water which needs treatment for PFAS before it can be distributed to the public or water that must be treated from a wastewater treatment plant. Southern California, Michigan and Wisconsin may be hotbeds for this market, as the states have adopted stringent regulations on PFAS limits in drinking water, and wastewater and significant initiatives have begun to implement systems to address the problem. The second market is treatment of contaminated groundwater and soils associated with military bases and airports. A good example of this in the US is the treatment of groundwater (and soil) affected by PFAS contamination caused by the use of fire-fighting foam, especially on military sites like Air Force bases. These sites are numerous and have significant groundwater and soil contamination problems which regulators are likely to require remediation for in the coming years. The third market is treatment for water intake or outfalls for industrial facilities which either use PFAS compounds in their industrial processes, or whose industrial processes are sensitive to PFAS contamination. BLEST intends to address each of these markets in the coming years, but will begin its first pilots and commercial projects in municipal water treatment and remediation of groundwater, as the need in those markets is most immediate according to prospective customers who have already approached BLEST management about projects.

COVID-19 Response and Related Business Development

In response to the COVID-19 crisis, and because of our technology portfolio’s specialty focus on iodine, at the outset of the pandemic we sponsored research with one of the country’s leading researchers in the study of pandemic diseases, Dr. Slobodan Paessler. Located at the Galveston National Laboratory at the University of Texas Medical Branch, his laboratory confirmed that our CupriDyne technology, as well as Clyraguard Personal Protection Spray (see the peer-reviewed publication on Clyraguard in F1000 Research at https://f1000research.com/articles/9-674), inactivated the Coronavirus that causes COVID-19: “CupriDyne technology was shown to be effective in inactivating the virus in a time-dependent manner, reducing virus titers by 99% (2 logs) after 30 minutes, and reducing virus titers to below the detection limit after 60 minutes. The novel iodine complex tested herein offers a safe and gentle alternative to conventional disinfectants for use on indoor and outdoor surfaces.” The actual report can be seen at the following link: https://www.biorxiv.org/content/10.1101/2020.05.08.082701v1. The CupriDyne abstract states:

“The coronavirus known as SARS-CoV-2, which causes COVID-19 disease, is presently responsible for a global pandemic wherein more than 3.5 million people have been infected and more than 250,000 killed to-date. There is currently no vaccine for COVID-19, leaving governments and public health agencies with little defense against the virus aside from advising or enforcing best practices for virus transmission prevention, which include hand-washing, physical distancing, use of face covers, and use of effective disinfectants. In this study, a novel iodine complex called CupriDyne® [technology] was assessed for its ability to inactivate SARS-CoV-2. CupriDyne was shown to be effective in inactivating the virus in a time-dependent manner, reducing virus titers by 99% (2 logs) after 30 minutes, and reducing virus titers to below the detection limit after 60 minutes. The novel iodine complex tested herein offers a safe and gentle alternative to conventional disinfectants for use on indoor and outdoor surfaces.” 

27

Following this initial study, the laboratory of Dr. Paessler conducted a follow-up study whereby a more concentrated CupriDyne formula (See CupriDyne Plus, below) was tested against the COVID-19 virus. In this study, the CupriDyne Plus completely inactivated SARS-CoV-2 (the COVID-19 virus) in 10 minutes – roughly the same performance observed with highly concentrated bleach. As a consequence of these highly promising results, we intend to fully explore any and all alternatives available to develop a new CupriDyne based product to help combat COVID-19 and secure appropriate regulatory approvals (see EPA Registration of CupriDyne Plus, below).

While we are actively engaged in responding the COVID-19 crisis, we have not ceased operations of our previous and long-term operating activities or plans and all phases of our development work and commercial activities have continued. However, our normal operations and rate of growth were negatively impacted during the crisis, namely with delays by our customers until such time as our customers operations resume some sense of normalcy. For example, our growth in the waste handling industry reversed course in March as operators, in light of the COVID-19 crisis, were less concerned about managing odor than during normal times. As the pandemic has progressed, and shelter-in-place orders have been lifted, these operating activities are increasing. In the third quarter of 2020, revenues from our odor and VOC control customers began to rebound, and as the fourth quarter began, this business unit had more than $400,000 in contracted projects for this current quarter (more detail on this can be found under Results from Operations).

In response to the pandemic, Clyra Medical launched Clyraguard Disinfecting Personal Protection Spray. This product is a safe, effective, FDA-registered Class I General Purpose disinfectant designed to decontaminate non-critical medical devices such as face masks and other personal protective equipment (PPE). The product has been proven effective against a wide range of bacteria, viruses, and fungi, and has been proven effective against SARS-CoV-2, the virus that causes COVID-19 disease. Given the product’s unique value proposition as an FDA-registered safe-on-skin and gentle disinfectant, we hope Clyraguard will experience rapid revenue growth as the word gets out and assuming our distribution channel partners are able to execute. The product is currently going through a staged roll-out plan with a robust manufacturing and supply chain, with distributers in the PPE and healthcare market recently coming online, and online retail channels such as Clyra’s new website and online store (www.clyraguard.com) and Amazon having recently launched. We are in discussions with distributors, resellers and marketing partners and expect to continue building out our selling resources. We also faced and have overcome numerous challenges as we began launching this product, including supply chain delays, a shortage of plastic bottles available to purchase, manufacturing and shipping delays.

Because of BioLargo’s efforts to quickly develop innovative solutions to aid in the COVID-19 pandemic, the company was one of three companies recognized by Octane, an Orange County based accelerator, for its COVID-19 response, and specifically its development of Clyraguard Disinfecting Personal Protection Spray.

ONM Environmental - Industrial Odor and VOC Solutions

ONM Environmental (previously known as Odor-No-More) generates most of its revenues through the sales of odor and VOC control products under the flagship brand CupriDyne Clean. Our CupriDyne Clean industrial products reduce and eliminate tough odors and VOC’s in various industrial settings, delivered through misting systems, sprayers, water trucks and similar water delivery systems. We believe the product is the number-one performing odor-control product in the market, and that it offers substantial savings to our customers compared with competing products. While sales of this product have increased over time, the company also began to expand its service offering due principally to the demands and needs of its major waste handling and industrial clients (which ultimately prompted the company to re-brand to “ONM Environmental” to reflect the widened scope of services it offers). ONM now holds General, Electrical, Plumbing and Low Voltage licenses and offers a menu of services to landfills, transfer stations, wastewater treatment facilities as well as facilities in non-waste related industries. These services include ongoing maintenance and on-site support services to assist our clients in the design and continued use of the various systems that deliver our liquid products in the field (such as misting systems). It has recently expanded these serves to engineering design, construction and installation.

Our customer base for our odor and VOC business was expanding prior to the COVID-19 crisis and we expect it to continue doing so once the world returns back to work. We have been and expect to continue selling product to the largest solid waste handling companies in the country. Opportunities for our products are available internationally. Very recently, some of the capital projects that ONM previously had on hold due to logistical limitations imposed by the COVID-19 pandemic have begun to come back online, with decision-makers from these clients requesting that ONM resume work on these projects.

28

We have in the past and plan to continue marketing these products through industry associations like the “Technology Approval Group” program offered by Isle Utilities that serves the wastewater treatment industry. We also have a number of potential partners actively engaged in commercial trials around the globe and we are actively in discussion with a number of groups to leverage our commercial focus through distribution partnerships.

Many of our customers have adopted CupriDyne Clean as a replacement for a non-performing and competitive products, some of which have been in use by customers for as many as 30 years. Upon using CupriDyne Clean, the majority of customers have expressed a very high degree of satisfaction with its performance compared to prior solutions. Because of this, we were realizing systematic adoption by our very large corporate customers and expect to resume the adoption cycle post crisis, to serve these customers for years to come. Our experience has helped refine our value proposition and assemble a comprehensive menu of products and services. Our success in this market has validated the market opportunity for our products and services and encourages us to continue investing in infrastructure and sales and marketing to increase revenues. We estimate there are approximately 2,000 active landfills¹, 8,000 transfer stations², and 15,000 wastewater treatment agencies³ in the United States. While all may not have ongoing odor problems or neighbor complaints, we believe many of the facilities have need for a disruptive odor solution like CupriDyne Clean.

Cannabis Industry

In 2019, we granted non-exclusive rights to Mabre Systems to sell our CupriDyne Clean product to the Cannabis industry under a private-label brand. Testing shows that CupriDyne Clean removes eliminates the odors emitted by Cannabis grow and production facilities. We have been installing CupriDyne Clean delivery misting systems for Mabre customers, and they continue to sell their branded CupriDyne Clean to clients in the industry. We continue to receive requests for CupriDyne Clean delivery system installations, and have over 20 facilities regularly buying product from our distributor. Mabre intends to launch a consumer odor product based on CupriDyne Clean in the near future.

South Korean Joint Venture

On February 12, 2020, we executed a “Joint Venture Framework Agreement” with a leading wastewater treatment solution provider based in South Korea (BKT Co. Ltd., “BKT”), to create a South Korean entity that would manufacture odor and VOC control products based on our CupriDyne Clean products. We received a $350,000 investment from BKT and issued 1,593,087 shares of our common stock, and invested $100,000 into the joint venture for a 40% ownership share. BKT and its U.S. based subsidiary invested $150,000 into the joint venture for the remaining 60% ownership share. Although the joint venture established manufacturing and is marketing the product, the COVID-19 pandemic has significantly impacted the expected growth of the company. Recently, the joint venture (under the name Odin) moved its headquarters to the Korea Water Cluster, which is a new world-renowned water innovation campus located in Daegu, South Korea, a center for industrial innovation in Asia.

Full Service Environmental Engineering

Our subsidiary BioLargo Engineering, Science & Technologies, LLC (“BLEST”) offers full service environmental engineering to third parties and provides engineering support services to our internal teams to accelerate the commercialization of our technologies. Its website is found at www.BioLargoEngineering.com.

BLEST focuses its efforts in three areas:

● Providing engineering services to third-party clients;

● Supporting internal product development and business units’ services to customers (e.g., the AOS) and

● Advancing their own technical innovations such as the AEC, legionella control systems.

The subsidiary is located in Oak Ridge (a suburb of Knoxville, Tennessee), and employs seven scientists and engineers who collectively worked together for almost 30 years and experience in diverse engineering fields. The team is led by Randall Moore, who served as Manager of Operations for Consulting and Engineering for the Knoxville office of CB&I Environmental & Infrastructure and was formerly a leader at The Shaw Group, Inc., a Fortune 500 global engineering firm. The other team members are also former employees of CB&I and Shaw. The team is highly experienced across multiple industries and they are considered experts in their respective fields, including chemical engineering, wastewater treatment (including design, operations, data gathering and data evaluation), process safety, energy efficiency, air pollution, design and control, technology evaluation, technology integration, air quality management & testing, engineering management, permitting, industrial hygiene, applied research and development, air testing, environmental permitting, HAZOP review, chemical processing, thermal design, computational fluid dynamics, mechanical engineering, mechanical design, NEPDES permitting, RCRA/TSCA compliance and permitting,  project management, storm water design & permitting, computer assisted design (CAD), bench chemistry, continuous emission monitoring system operator, data handling and evaluation and decommissioning and decontamination of radiological and chemical contaminated facilities.

29

BLEST is comprised of industry veterans with experience in executing high-profile environmental engineering projects (like anthrax for the US Postal Service, remediation work post Katrina, the largest dioxin remediation in USA) and served as technical leaders with one of the largest global engineering firms before agreeing to join the BioLargo family of companies as owner operators. They are well-recognized for the value they provide to high-profile clients including the US Air Force, a recent win with one of the global leaders in chemical manufacturing, a leading food producer in the USA and more. As an example, BLEST was awarded a contract to assist in the reconfiguration of the Regenerative Thermal Oxidizer (RTO) systems used at a large chemical manufacturing plant on the East Coast, owned by a global chemical company, that produces phenolic resins, antioxidants and related synthetic organic products. The contract is expected to execute with a series of milestones through mid-2021, with anticipated scope expanding the contract period to at least 24 months and over $500,000 in total revenue.

New Technology – Mineral Extraction

BLEST developed a proprietary and patent-pending process to extract valuable minerals from certain types of industrial waste. As a consequence of this new process, a client is planning a substantial long-term project expected to generate over $1B in revenues, avoiding expensive remediation costs. As the client’s engineering services provider, and developer of the extraction technology, BLEST is in discussions with the client to secure its role as the project manager and/or lead engineer. We believe there are a number of similarly situated industrial waste sites across the country and around the world that would benefit from our newly developed process, and, as resources permit, we intend to explore these opportunities.

BioLargo Water and the Advanced Oxidation System – AOS

BioLargo Water is our wholly owned subsidiary located on campus at the University of Alberta, Canada, that, until recently, has been primarily engaged in the research and development of our Advanced Oxidation System (AOS).  The AOS is our patented water treatment device that generates a series of highly oxidative species of iodine and other molecules that, because of its proprietary configuration and inner constituents, allow it to eliminate pathogenic organisms and organic contaminants as water passes through the device and it performs with extreme efficacy while consuming very little electricity. Its key application is extremely efficient decontamination and the disinfection of various waste waters. The key value proposition of the AOS is its ability to eliminate a wide variety of contaminants with high performance while consuming extremely low levels of input electricity and extremely low levels of chemistry inputs – a trait made possible by the complex set of highly oxidative iodine compounds generated within the AOS reactor. Our proof-of-concept studies and case studies have generated results that project the AOS will be more cost- and energy-efficient than commonly used advanced water treatment technologies such as UV, electro-chlorination, and ozonation. This value proposition sets the AOS technology above other water treatment options, as we believe the AOS may allow safe and reliable water treatment for significantly lower cost compared to its competitors and may even enable advanced water treatment in applications where it otherwise would have been prohibitively costly. Secondly, the AOS has been proven effective against certain soluble organic molecules, pharmaceuticals and a host of micropollutants, which are difficult to treat with other conventional tertiary water treatment technologies like UV. This characteristic of the AOS may offer a significant incentive for prospective customers to choose this technology over established incumbents because of the need in certain contexts to address these hard-to-treat contaminants, in addition to traditional targets of tertiary treatment like microorganisms.

The AOS has the potential to allow reliable and cost-effective water treatment in numerous industries and applications where high-level disinfection or elimination of hard-to-treat organic contaminants is required. We believe the total serviceable market for our AOS is $10.75 billion for the poultry processing, food & beverage, and storm water segments with a target beachhead market for poultry processing in North America at an estimated $240 million.

Sunworks Farm pilot

Our efforts to establish our first commercial pilot for the AOS system, at a poultry and livestock farm in Alberta, Canada, is progressing as planned. We expect to have installed a fully functional treatment train featuring our AOS water system at the client’s farm in the first or second quarter 2021. When complete, the system will be the first of its kind to allow for the complete reuse of this industrial wastewater, allowing the client to expand production and significantly save on water costs. The project budget of approximately $600,000 will be funded in part by government grants and in part by the client. We are finalizing grant funding, and have been working with government regulators.

30

If successful, this project will set a precedent for the AOS and BioLargo’s total water treatment solutions for future customers seeking water reuse, or even “zero liquid discharge” systems, and we believe will lead to follow-up projects with customers who follow Sunworks’ example.  

Wastewater Treatment Pilot - Montreal

BioLargo Water is working on a second AOS demonstration pilot, to be installed at a municipal wastewater treatment facility near Montreal, Quebec, to be run in partnership with acclaimed water experts at the Centre des Technologies de L’Eau (CTE). BLEST engineers are building the AOS unit. The purpose of the project is to assess the AOS (and eventually, an AEC unit to be added on to the treatment train) as effective, cost-efficient, and complementary solutions for disinfecting and eliminating a broad range of recalcitrant contaminants from municipal wastewater in an operating wastewater treatment plant.It is our belief that once these pre-commercial pilots have concluded with the AOS, our ability to entice major water industry players to partner with BioLargo Water to accelerate market adoption of the AOS will be increased dramatically.

Clyra Medical Technologies

We initially formed Clyra Medical to commercialize our technology in the medical products industry, which we believe can be disruptive to many competing product lines.

When the COVID-19 crisis began, we immediately responded by supporting the team at Clyra Medical in any way possible to help them create Clyraguard Personal Protection Spray. Testing has confirmed that Clyraguard inactivates the COVID-19 pandemic coronavirus, and these data have been published in a peer-reviewed journal called Faculty 1000 Research (https://f1000research.com/articles/9-674). See details above in “COVID-19 Response and Related Business Development.”

Recently Clyra Medical Technologies has welcomed two key team members to its roster. The company recruited Shawn Dougherty, experienced C-level executive responsible for several successful high-profile product launches, to serve as Clyra’s Chief Revenue Officer. Prior to joining Clyra, Shawn co-founded Mophie, the number one selling battery case manufacturer for mobile devices in North America. As COO and founder, she helped Mophie create the first juice pack battery case for the iPhone in North America and built an exclusive partnership with Apple. Clyra also recruited John A. Sirpilla to serve as its Chief Business Development Officer, where he is working with Clyra’s senior executive team on brand expansion and retail channel development, and will work to develop strategic partnerships to help make Clyra products widely available to individuals, businesses, and the healthcare industry. Mr. Sirpilla is the former President of Camping World Accessory Stores, a 140-store nationwide retail chain serving the RV industry and was promoted in 2012 to Chief Business Development Officer for the parent company, Camping World and Good Sam with annual sales of nearly $4 billion.

CupriDyne Plus

BioLargo’s CupriDyne® technology has been used successfully and safely for years to oxidize airborne contaminants like VOCs and other odor-causing compounds.

At the outset of the Covid-19 pandemic, we set out to revisit and modify the CupriDyne technology with the goal of creating a powerful yet comparatively safer, non-toxic, and environmentally friendly disinfectant and/or surface sanitizer. The result of this redevelopment process, which involved over 500 hours by our engineers and scientists, was CupriDyne Plus, a product that delivers a potent concentration of the active ingredient iodine (I-2) as compared to traditional CupriDyne based formulations, meaning it can achieve much faster results..

We are actively working to obtain an EPA registration for CupriDyne Plus for a number of different applications (see EPA Registration, below), and we are optimistic about those efforts. CupriDyne Plus has the potential to offer a safer, more environmentally friendly alternative to bleach and other common antimicrobials for applications like hard surface disinfection, sanitization of non-porous non-food contact surfaces, disinfection of air, textiles, and more.

EPA Registration of CupriDyne Plus

We intend to pursue registration of CupriDyne Plus as a hard surface disinfectant and/ or sanitizer. Doing so would allow us to expand our label and marketing claims such that it would compete against less gentle and less environmentally sensitive chemicals being used in competing products. Since research demonstrated that CupriDyne Plus kills the SARS-CoV-2 coronavirus that has caused the current global pandemic, we knew there was a need for a safe alternative to cleaning agents such as bleach. Our scientists have spent more than 600 hours testing the product against EPA standards. Based on our extensive work, we are confident it meets the minimum performance requirements required for EPA registration as a disinfectant and/or surface sanitizer. We have met with and presented data to officials at the EPA for the purpose of refining our product and determining additional data requirements, and have retained a firm specializing in EPA registration work to help us through the process. While we are not able to predict the results of any EPA application we submit, or the time it will take to complete the process, we believe the market opportunities are large, with the U.S. market for surface disinfectants coming in at greater than $3.4 billion (https://www.grandviewresearch.com/industry-analysis/surface-disinfectant-market), and that we will ultimately be successful in obtaining registration.

Results of Operations

We operate our business in distinct business segments:

● ONM Environmental, which manufactures and sells our odor and VOC control products and services, including our flagship product, CupriDyne Clean;

● BLEST, our professional engineering services division supporting our internal business units, advancing innovations like the AEC to remove PFAS contaminants from water, and serving outside clients on a fee for service basis;

● Clyra Medical, our partially owned subsidiary which develops and sells medical products based on our technology, including the recently released Clyraguard Personal Protection Spray; and

● BioLargo Water, our Canadian division that has been historically pure research and development, and is now transitioning to focus on commercializing our AOS system and supporting the work to advance CupriDyne technology-based products through an EPA registration;

● Our corporate operations, which support the operating segments with legal, accounting, human resources, and other services.

Consolidated revenue for the three and nine months ended September 30, 2020 was $666,000 and $1,522,000, which is a 26% and 15% increase over the same periods in 2019. Sales at our operating divisions decreased upon the initial shutdown of California and most the U.S. in late March due to the COVID-19 pandemic, but have since rebounded. Our product revenue includes sales of our CupriDyne Clean industrial odor control product, Clyraguard Personal Protection Spray, and hand sanitizers. We expect revenues to continue to increase in the foreseeable future, as our operating divisions have significant contracted-for work in the pipeline. Given its brief experience with the product, Clyra’s management is unable to identify any definitive trends in the sales of Clyraguard Personal Protection Spray, which are in large part dependent on the success of third-party sales agents and distributors and thus out of its control. Its recent addition to the Amazon selling platform is being managed by a professional marketing and sales group that is actively testing and refining the product offering, its messaging and related marketing. As a product focused on the COVID-19 pandemic, sales of the product are also in-part dependent on the length of the pandemic and consumer’s wiliness to spend money on personal protective equipment.

ONM Environmental (formerly, Odor-No-More)

Our wholly owned subsidiary ONM Environmental generated revenues through sales of its flagship product CupriDyne Clean, by providing design, installation, and maintenance services on the systems that deliver CupriDyne Clean at its clients’ facilities, and through other related products. Of its gross sales in the three and nine months ended September 30, 2020, approximately two-thirds were to the waste handling industry.

Revenue (ONM)

ONM’s revenues for the three and nine months ended September 30, 2020, were $356,000 and $952,000, a decrease of $60,000 and $40,000 from the same periods in 2019. Sales on a quarter-to-quarter basis had been increasing until the COVID-19 pandemic shut down businesses across the country, and have since started to rebound. ONM has multiple contracts scheduled for completion in the fourth quarter that had been delayed due to the pandemic.

Cost of Goods Sold (ONM)

ONM’s cost of goods sold includes costs of raw materials, contract manufacturing, and portions of depreciation, salaries and expenses related to the manufacturing and installation of its products. As a percentage of revenue, ONM’s costs of goods improved 7% and 5% in the three and nine months ended September 30, 2020 to 36% and 39%. The decrease in cost of goods is due to increase sales of higher-margin products, an increase in product prices, and a slight decrease in the cost of our raw materials resulting from increased purchasing power.

Selling, General and Administrative Expense (ONM)

ONM’s selling, general and administrative expenses increased by 25% to $996,000 during the nine months ended September 30, 2020. These expenses have increased alongside its efforts to increase revenues by hiring additional sales and support staff. We expect these expenses to increase when compared to 2019 but remain consistent in 2020 unless and until its revenues increase.

32

Net Loss (ONM)

For the nine months ended September 30, 2020, ONM generated $952,000 in revenue, a gross margin of $565,000, total costs and expenses of $996,000, and a tax credit of $10,000, resulting in a net loss of $421,000. For the three months ended September 30, 2020, ONM generated $356,000 in revenue, a gross margin of $228,000, had total costs and expenses of $371,000, and a tax credit of $2,000, resulting in a net loss of $142,000.

BLEST (engineering division)

Revenue (BLEST)

Our engineering segment (BLEST) generated $160,000 and $436,000 of revenues from third party clients in the three and nine months ended September 30, 2020, an increase of $22,000 and $126,000 from the same periods in 2019. The increases this year compared with 2019 is due to an increase in the number of client contracts being serviced. BLEST revenues reported on our consolidated statement of operations do not include work performed on internal BioLargo projects, such as its engineering and development of the AOS water filtration system, development of the AEC to combat the PFAS crisis (see Development of AEC to Combat PFAS Crisis, above), and other projects included in research and development.

Cost of Goods (Services) Sold (BLEST)

BLEST’s cost of services includes employee labor as well as subcontracted labor costs. In the three and nine months ended September 30, 2020, its cost of services were 74% and 78% of its revenues, versus 68% and 74% in the comparable periods in 2019, as a result of an increased use of subcontracted labor.

Selling, General and Administrative Expense (BLEST)

BLEST’S SG&A expenses include expense related to its operations, although because it primarily delivers services to its clients, most of its labor costs are included in its cost of services (for third party clients), and in research and development for its work on BioLargo technologies. BLEST selling, general and administrative expenses during the nine months ended September 30, 2020 totaled $300,000 compared to $331,000 for the nine months ended September 30, 2019.

Net Loss (BLEST)

For the nine months ended September 30, 2020, BLEST generated $443,000 in revenue, a gross margin of $107,000, and had total costs and expenses of $572,000, resulting in a net loss of $465,000. Reported revenue does not include revenue billed by BLEST to other BioLargo operating divisions, which are not paid in cash, and eliminated in the consolidation of our financial statements. It is important to note that BLEST’s net loss would be eliminated if it were an outside contract-for-hire services company selling services to our water company or our industrial odor and VOC control operating unit.

Other Income

Our wholly owned Canadian subsidiary has been awarded more than 80 research grants over the years from various Canadian public and private agencies, including the Canadian National Research Institute – Industrial Research Assistance Program (NRC-IRAP), the National Science and Engineering Research Council of Canada (NSERC), and the Metropolitan Water District of Southern California’s Innovative Conservation Program “ICP”. The research grants received are considered reimbursement grants related to costs we incur and therefore are included as Other Income. We continued to win grants and it is important to note that amounts paid directly to third parties are not included as revenue in our financial statements.

Although we are continuing to apply for government and industry grants, and indications from the various grant agencies is highly encouraging, we cannot be certain of continuing those successes in the future.

33

Selling, General and Administrative Expense – consolidated

Our SG&A expenses include both cash expenses (for example, salaries to employees) and non-cash expenses (for example, stock option compensation expense). Our SG&A expenses increased by $108,000 (6%) and $799,000 (18%) in the three and nine months ended September 30, 2020, compared to the three and nine months ended September 30, 2019, due primarily to increases in salaries and payroll of $162,000 and $464,000 and sales and marketing of $44,000 and $88,000 in the three and nine months ended September 30, 2020 versus 2019, offset by a reduction of professional fee and consulting expense during the three months ended September 30, 2020. Much of the increase is due to non-cash expenses related to the issuance of stock options, and the hiring of sales personnel. Our employees, vendors and consultants chose to receive a greater number of stock and stock options in lieu of cash owed and as part of an employee retention program. The largest components of our SG&A expenses included (in thousands):

	Three months ended:				Nine months ended:
	September 30, 2019		September 30, 2020		September 30, 2019		September 30, 2020
Salaries and payroll related	$	624	$	786	$	1,594	$	2,061
Professional fees		194		125		554		597
Consulting		474		449		1,067		1,134
Office expense		281		260		744		750
Sales and marketing		70		114		162		250
Investor relations		63		35		145		139
Board of director expense		97		77		232		198

The increase in salaries and payroll expenses is related to the implementation of stock option bonus compensation programs for employees. Professional fees have varied over time due to occasional increases and increases in our need for those services. Consulting expenses have increased, as well as sales and marketing and investor relations, as the Company has increased efforts to sell its products and services and increased efforts in the capital markets. Board of director expenses varied from prior periods due to stock options issued in 2019.

Research and Development

In the three and nine months ended September 30, 2020, we spent approximately $347,000 and $1,031,000 in the research and development of our technologies and products. This was an increase of 5% and a decrease of 8% compared to the same periods in 2019, due to increased needs to develop sales and production objectives and less on further research.

Interest expense 

Our interest expense for the three and nine months ended September 30, 2020 was $318,000 and $1,823,000, a decrease of 75% and 34% compared to the same periods in 2019. The decreases in the 2020 periods are due to non-cash expenses from warrants issued to investors in our OID convertible note offering incurred in 2019. All of the OID investments have converted and the discount fully amortized to interest, therefore we have less debt and less interest.

Loss on extinguishment of debt

In the three months ended September 30, 2020, we recorded a loss on extinguishment of debt related to the extension of a due date for convertible note payable. In exchange for the due date extension, we reduced the note conversion price from $0.17 to $0.14 and extended the expiration date of warrants held by the note holder by one and two years. The fair value of these concessions resulted in a fair value totaling $228,000, which was recorded as loss on extinguishment.

In the nine months ended September 30, 2020, we recorded a loss on extinguishment of debt related to transactions with current vendor and employees where Clyra Medical is unable to pay obligations in cash. In lieu of cash, the vendors and employees accepted options to purchase shares of Clyra stock. The fair value of those options exceeded the debt that was converted by $214,000.

In the three months ended September 30, 2019, we recorded a loss on extinguishment of debt related to transactions with prior investors to extend the maturity dates of promissory notes. As consideration, we increased principal amounts, modified conversion terms, and/or issued stock purchase warrants. We had no such activities in the comparable period in 2020. We extended the maturity dates of the promissory notes due to a lack of sufficient cash to satisfy the obligations at maturity. Unless our cash position changes substantially, we anticipate we will continue to do so as additional notes come due.

Net Loss

Net loss for the three months ended September 30, 2020 was $2,390,000, a loss of $0.01 per share, compared with $3,886,000 and $0.02 per share in the prior year comparable period. Net loss for the nine months ended September 30, 2020 was $7,707,000, a loss of $0.04 per share, compared to a net loss for the nine months ended September 30, 2019 of $8,625,000, a loss of $0.06 per share. The decrease in net loss in the 2020 periods is primarily due to decreased interest expenses.

34

The net loss per business segment is as follows (in thousands):

	Three months ended						Nine months ended
	September 30, 2019			September 30, 2020			September 30, 2019			September 30, 2020
BioLargo corporate		(3,393	)		(1,374	)		(6,985	)		(4,954	)
ONM Environmental		(119	)		(142	)		(260	)		(421	)
Clyra Medical		(351	)		(528	)		(982	)		(1,493	)
BLEST		27			(298	)		(110	)		(465	)

Net loss		(3,886	)		(2,390	)		(8,625	)		(7,707	)

Liquidity and Capital Resources

For the nine months ended September 30, 2020, we had a net loss of $7,707,000, used $3,318,000 cash in operations, and at September 30, 2020, we had a working capital deficit of $1,316,000, and current assets of $1,873,000. We do not believe operating profits in the immediate future will be sufficient to fund our current level of operations. We have been, and anticipate that we will continue to be, limited in terms of our capital resources. None of our business segments have ever generated enough revenues to fund their operations, or to contribute to our corporate operations or overhead. Thus, in light of our cash position at year end, in order to continue operations, in calendar year 2020 we have continued to sell our stock in private securities offerings and to Lincoln Park (see Note 3). Thus far this year, we have received approximately $1.7 million from Lincoln Park (an average of approximately $160,000 per month). The proceeds we receive from stock sales to Lincoln Park is a function of stock price and volume – a lower stock price and less trading volume results in less money we can receive from Lincoln Park. Although we have relied on investment funds through our agreement with Lincoln Park this year, there is no assurance that it will continue to provide the funds we need for our operations, and if it does not, we will have to rely on other forms of financing, and there is no assurance that we will be able to do so, or if we do so, it will be on favorable terms. We also regularly pay officers and vendors equity in lieu of cash, and anticipate that we will continue to be able to do so in the future. The foregoing factors raise substantial doubt about our ability to continue as a going concern, unless we are able to continue to raise funds through stock sales to Lincoln Park or other private financings, and in the long term, our ability to attain a reasonable threshold of operating efficiencies and achieve profitable operations by licensing or otherwise commercializing products incorporating our technologies. The consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

Critical Accounting Policies

Our discussion and analysis of our results of operations and liquidity and capital resources are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, valuation of offerings of debt with equity or derivative features which include the valuation of the warrant component, any beneficial conversion feature and potential derivative treatment, and share-based payments. We base our estimates on anticipated results and trends and on various other assumptions that we believe are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results that differ from our estimates could have a significant adverse effect on our operating results and financial position. We believe that the following significant accounting policies and assumptions may involve a higher degree of judgment and complexity than others.

The methods, estimates and judgments the Company uses in applying these most critical accounting policies have a significant impact on the results of the Company reports in its financial statements.

Revenue Recognition

We adopted ASU 2014-09, “Revenue from Contracts with Customers”, Topic 606, on January 1, 2018. The guidance focuses on the core principle for revenue recognition.

The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps:

Step 1: Identify the contract(s) with a customer.

35

Step 2: Identify the performance obligations in the contract.

Step 3: Determine the transaction price.

Step 4: Allocate the transaction price to the performance obligations in the contract.

Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

We have revenue from three subsidiaries, ONM, BLEST and Clyra. ONM and Clyra identify its contract with the customer through a written purchase order, in which the details of the contract are defined including the transaction price and method of shipment. The only performance obligation is to create and ship the product and each product has separate pricing. Revenue is recognized at a point in time when the order for its goods are shipped if its agreement with the customer is FOB manufacturer, and when goods are delivered to its customer if its agreement with the customer is FOB destination. Revenue is recognized with a reduction for sales discounts, as appropriate and negotiated in the customer’s purchase order. ONM also installs misting systems for which it bills on a time and materials basis. It identifies its contract with the customer through a written purchase order in which the details of the time to be billed and materials purchased and an estimated completion date. The performance obligation is the completion of the installation. Revenue is recognized over time as the work is performed.

BLEST identifies services to be performed in a written contract, which specifies the performance obligations and the rate at which the services will be billed. Each service is separately negotiated and priced. Revenue is recognized as services are performed and completed. BLEST’s contracts typically call for invoicing for time and materials incurred for that contract. A few contracts have called for milestone or fixed cost payments where BLEST bills an agreed to amount per month for the life of the contract. In these instances, completed work, billed hourly, is recognized as revenue. If the billing amount is greater or lesser than the completed work, a receivable or payable is created. These accounts are adjusted upon additional billings as the work is completed. To date, there have been no discounts or other financing terms for the contracts. 

In the future, we may generate revenues from royalties or license fees from our intellectual property. In the event we do so, we anticipate a licensee would pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. Upon entering into a licensing agreement, we will determine the appropriate method of recognizing the royalty and license fees.

Warrants and Conversion Features

Warrants issued with our convertible and non-convertible debt instruments are accounted for under the fair value and relative fair value method.

The warrant is first analyzed per its terms as to whether it has derivative features or not. If the warrant is determined to be a derivative and not qualify for equity treatment, then it is measured at fair value using the Black Scholes option model, and recorded as a liability on the balance sheet. The warrant is re-measured at its then current fair value at each subsequent reporting date (it is “marked-to-market”).

If the warrant is determined to not have derivative features, it is recorded into equity at its fair value using the Black Scholes option model, however, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the convertible note.

Convertible debt instruments are recorded at fair value, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the warrant. Further, the convertible debt instrument is examined for any intrinsic beneficial conversion feature (“BCF”) of which the conversion price is less than the closing common stock price on date of issuance. If the relative fair value method is used to value the convertible debt instrument and there is an intrinsic BCF, a further analysis is undertaken of the BCF using an effective conversion price which assumes the conversion price is the relative fair value divided by the number of shares the convertible debt is converted into by its terms. The BCF value is accounted for as equity.

The warrant and BCF relative fair values are also recorded as a discount to the convertible promissory notes. At present, these equity features of the convertible promissory notes have recorded a discount to the convertible notes that is substantially equal to the proceeds received.

Share-based Payments

It is the Company’s policy to expense share-based payments as of the date of grant or over the term of the vesting period in accordance with Auditing Standards Codification Topic 718 “Share-Based Payment.” Application of this pronouncement requires significant judgment regarding the assumptions used in the selected option pricing model, including stock price volatility and employee exercise behavior. Most of these inputs are either highly dependent on the current economic environment at the date of grant or forward-looking expectations projected over the expected term of the award.

36

 Fair Value Measurement

Generally accepted accounting principles establishes a hierarchy to prioritize the inputs of valuation techniques used to measure fair value. The hierarchy gives the highest ranking to the fair values determined by using unadjusted quoted prices in active markets for identical assets (Level 1) and the lowest ranking to fair values determined using methodologies and models with unobservable inputs (Level 3). Observable inputs are those that market participants would use in pricing the assets based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company’s assumptions about inputs market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The Company has determined the appropriate level of the hierarchy and applied it to its financial assets and liabilities.

Management believes the carrying amounts of the Company’s financial instruments as of December 31, 2019 and September 30, 2020, approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, convertible notes, and other assets and liabilities.

Item 4. Controls and Procedures

We conducted an evaluation, under the supervision and with the participation of management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Report.

Our procedures have been designed to ensure that the information relating to our company, including our consolidated subsidiaries, required to be disclosed in our SEC reports is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow for timely decisions regarding required disclosure. However, our Company is continuing to grow and evolve in 2018, as we have added a new accounting manager for ONM and the engineering division and implemented more detailed reviews of the accounting records. In late 2017, we added an engineering division operating in Tennessee. The volume of our product sales continues to grow, increasing strain on our accounting systems. And, our operations do not yet generate enough cash to fund operations, and thus we rely on financing activities to maintain our level of operations and fund our anticipated growth. These activities put stress on our overall controls and procedures. Although we have made some improvements, our chief executive officer and chief financial officer have concluded that, as of the evaluation date, our disclosure controls and procedures were not effective, due to the material weakness identified below.

It should be noted that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets; (ii) 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 are being made only in accordance with authorizations of management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Under the supervision and with the participation of our management, including our chief executive officer and the chief financial officer, we have established internal control procedures in accordance with the guidelines established in the 2013 Framework —Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Recognizing the dynamic nature and growth of the Company’s business, its business segments operating in multiple locations, and the lack of sophisticated reporting systems, management recognizes the strain on the overall internal control environment. As a result, management has concluded that its internal controls over financial reporting are not effective. Management identified a material weakness with respect to deficiencies in its financial closing and reporting procedures. Management believes this is due to a lack of resources. Management intends to add accounting personnel and operating staff and more sophisticated systems in order to improve its reporting procedures and internal controls, subject to available capital. A material weakness is a significant deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected. There was no further change in our internal control over financial reporting that occurred during the nine-month period covered by this Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls or our internal control over financial reporting, or any system we design or implement in the future, will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Item 2.  Unregistered Sales of Equity Securities and Use of Proceeds

The following is a report of the sales of unregistered securities during the period covered by this report not previously reported in an annual report on Form 10-K, a Quarterly Report on Form 10-Q, or a Current Report on Form 8-K.

In the three months ended September 30, 2020, we issued 24,776,554 shares of our common stock in conversion of principal and interest due on convertible promissory notes in the principal amount of $2,286,000.

In the three months ended September 30, 2020, we received gross and net proceeds of $125,000 and issued 746,528 shares of our common stock pursuant to a Unit Offering whereby we accepted investments and issued units consisting of shares of common stock, a six-month stock purchase warrant, and a five-year stock purchase warrant, at unit prices of $0.16 and $0.18. The number of shares issued to each investor, and purchasable by each warrant, is the quotient of the unit price and investment amount. The exercise price of each six-month warrant is 120% of the unit price, and for the six-month warrant, 150% of the unit price. So long as 18 months has passed and the warrant shares are not registered with the SEC, the warrants allow for cashless exercise.

In the three months ended September 30, 2020, we issued 189,762 shares of our common stock to vendors in exchange for reduction of $28,000 of amounts owed.

All of these offerings and sales were made in reliance on the exemption from registration contained in Section 4(2) of the Securities Exchange Act and/or Regulation D promulgated thereunder as not involving a public offering of securities.

Business and Organization

Description of Business

BioLargo, Inc. is an innovative technology developer and environmental engineering company driven by a mission to "make life better" by delivering robust, sustainable solutions for a broad range of industries and applications, with a focus on clean water, clean air. The company also owns a minority interest in an advanced wound care subsidiary that has licensed BioLargo Technologies and it plans to spin out or sell when the appropriate opportunity is identified.  Our business strategy is straightforward: we invent or acquire technologies that we believe have the potential to be disruptive in large commercial markets; we develop and validate these technologies to advance and promote their commercial success as we leverage our considerable scientific, engineering, and entrepreneurial talent; we then monetize these technical assets through a variety of business structures that

may

include licensure, joint venture, sale, spin off, or by deploying direct to market strategies.

Liquidity / Going concern

For the

nine

months ended

September 30, 2020,

we had a net loss of

$7,707,000,

used

$3,318,000

cash in operations, and at

September 30, 2020,

we had a working capital deficit of

$1,316,000,

and current assets of

$1,873,000.

We do

not

believe operating profits in the immediate future will be sufficient to fund our current level of operations. We have been, and anticipate that we will continue to be, limited in terms of our capital resources.

None

of our business segments (see Note

10,

“Business Segment Information”) have ever generated enough revenues to fund their operations, or to contribute to our corporate operations or overhead. Thus, in light of our cash position at year end, in order to continue operations, in calendar year

2020

we have continued to sell our stock in private securities offerings and to Lincoln Park (see Note

3

). Thus far this year, we have received approximately

$1.7

million from Lincoln Park (an average of approximately

$160,000

per month). The proceeds we receive from stock sales to Lincoln Park is a function of stock price and volume – a lower stock price and less trading volume results in less money we can receive from Lincoln Park. Although we have relied on investment funds through our agreement with Lincoln Park this year, there is

no

assurance that it will continue to provide the funds we need for our operations, and if it does

not,

we will have to rely on other forms of financing, and there is

no

assurance that we will be able to do so, or if we do so, it will be on favorable terms. We also regularly pay officers and vendors equity in lieu of cash, and anticipate that we will continue to be able to do so in the future. The foregoing factors raise substantial doubt about our ability to continue as a going concern, unless we are able to continue to raise funds through stock sales to Lincoln Park or other private financings, and in the long term, our ability to attain a reasonable threshold of operating efficiencies and achieve profitable operations by licensing or otherwise commercializing products incorporating our technologies. The consolidated financial statements do

not

include any adjustments that might be necessary if we are unable to continue as a going concern.

Organization

We are a Delaware corporation formed in

1991.

We have

four

wholly-owned subsidiaries: BioLargo Life Technologies, Inc., organized under the laws of the State of California in

2006;

ONM Environmental, Inc. (formerly, Odor-

No

-More, Inc.), organized under the laws of the State of California in

2009;

BioLargo Water Investment Group Inc. organized under the laws of the State of California in

2019,

which wholly owns BioLargo Water, Inc., organized under the laws of Canada in

2014;

and BioLargo Development Corp., organized under the laws of the State of California in

2016.

Additionally, we own

97.5%

(see Note

9

) of BioLargo Engineering Science and Technologies, LLC (“BLEST”), organized under the laws of the State of Tennessee in

2017.

We also own

47%

of Clyra Medical Technologies, Inc. (“Clyra Medical”), organized under the laws of the State of California in

2012,

and consolidate their financial statements (see Note

2,

subheading “Principles of Consolidation,” and Note

8

).

The unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to Rule

8

-

03

of Regulation S-

X

under the Securities Act of

1933,

as amended. Accordingly, they do

not

include all of the information and notes required by generally accepted accounting principles for annual financial statements.  In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. We are still operating in the early stages of the sales and distribution process, and therefore our operating results for the

three

and

nine

months ended

September 30, 2020,

are

not

necessarily indicative of the results that

may

be expected for the year ending

December 

31,

 

2020,

or for any other period. These unaudited consolidated financial statements and notes should be read in conjunction with the Company's audited consolidated financial statements and accompanying notes included in the Annual Report on Form

filed with the Securities and Exchange Commission (the “SEC”) on

Note

Summary of Significant Accounting Policies

In the opinion of management, the accompanying balance sheet and related statements of operations, cash flows, and stockholders' deficit include all adjustments, consisting only of normal recurring items, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, and its wholly- and partially-owned subsidiaries, including Clyra Medical. Management believes Clyra Medical's financial statements are appropriately consolidated with that of the Company after reviewing the guidance of ASC Topic 

810

,

 “Consolidation”, and concluding that BioLargo controls Clyra Medical. While BioLargo does

not

have voting interest control through a majority stock ownership of Clyra Medical (it owns

47%

of the outstanding voting stock), it does exercise control under the “Variable Interest Model”: there is substantial board overlap, BioLargo is the primary beneficiary since it has the power to direct Clyra Medical's activities that most significantly impact Clyra Medical's performance, and it has the obligation to absorb losses or receive benefits (through royalties and licensing) that could be potentially significant to Clyra Medical. BioLargo has consolidated Clyra Medical's operations for all periods presented. (See Note

8.

)

All intercompany accounts and transactions have been eliminated. 

Foreign Currency

The Company has designated the functional currency of BioLargo Water, Inc., our Canadian subsidiary, to be the Canadian dollar. Therefore, translation gains and losses resulting from differences in exchange rates are recorded in accumulated other comprehensive income.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of

three

-months or less when acquired to be cash equivalents. Substantially all cash equivalents are held in short-term money market accounts at

one

of the largest financial institutions in the United States. From time to time, our cash account balances are greater than the Federal Deposit Insurance Corporation insurance limit of

$250,000

per owner per bank, and during such times, we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the financial institution. We do

not

anticipate non-performance by our financial institution.

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts as of 

December 31, 2019 

was

$24,000

and

September 30, 2020

was 

$35,000.

Credit Concentration

We have a limited number of customers that account for significant portions of our revenue. For the

nine

months ended

September 30, 2019

and

2020,

each period had

two

customers that accounted for

10%

or more of our consolidated revenues, as follows:

	September 30 , 2019			September 30 , 2020
Customer A	<10		%		12	%
Customer B		13	%	<10		%
Customer C		10	%	<10		%

We had

two

customers that accounted for more than

10%

of consolidated accounts receivable at

December 31, 2019

and

three

customers that accounted for more than

10%

of consolidated accounts receivable at

September 30, 2020,

as follows:

	December 31, 2019			September 30 , 2020
Customer A	<20		%		15	%
Customer D	<10		%		15	%
Customer E	<10		%		10	%
Customer F		14	%	<10		%
Customer G		13	%	<10		%

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. The allowance for obsolete inventory as of 

December 31, 2019

and

September 30, 2020

was

$3,000

.

 As of

December 31, 2019,

and

September 30, 2020,

inventories consisted of (in thousands):

	December 31, 2019		September 30 , 2020
Raw material	$	11	$	180
Finished goods		5		112
Total	$	16	$	292

Other Non-Current Assets

Other non-current assets consisted of (i) security deposits of

$35,000

related to our business offices, and (ii) prepaid consulting fees from the issuance of Clyra Medical stock, resulting in a fair value of

$787,500

(see Note

8

In

February 2016,

the FASB issued ASU Update

No.

2016

-

02,

“Leases,” which requires lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability, and lessors to recognize a net lease investment. Additional qualitative and quantitative disclosures are also required. We adopted this standard effective

January 1, 2019

using the effective date option, which resulted in a

$399,000

gross up of assets and liabilities; this balance

may

fluctuate over time as we enter into new leases, extend or terminate current leases. Upon the transition to the ASC

842,

the Company elected to use hindsight as a practical expedient with respect to determining the lease terms (as we considered our updated expectations of acceptance of the Westminster California facility lease renewal) and in assessing any impairment of right-of-use assets for existing leases.

No

impairment is expected at this time. As of

September 30, 2020,

the right-of-use assets on our balance sheet related to our operating leases totals

$356,000.

Impairment

Long-lived and definite lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset

may

not

be recoverable. If the sum of the expected future undiscounted cash flows from the use of the asset and its eventual disposition is less than the carrying amount of the asset, then an impairment loss is recognized. The impairment loss is measured based on the fair value of the asset. Any resulting impairment is recorded as a reduction in the carrying value of the related asset in excess of fair value and a charge to operating results. As of

September 30, 2019

and

2020,

management determined that there was

no

impairment of its long-lived assets, including its In-process Research and Development at Clyra Medical (see Note

8

).

Equity

Method of

Accounting

On

March 20, 2020,

we invested

$100,000

into a South Korean entity (Odin Co. Ltd., “Odin”) pursuant to a Joint Venture agreement we had entered into with BKT Co. Ltd. and its U.S. based subsidiary, Tomorrow Water. We received a

40%

non-dilutive equity interest, and BKT and Tomorrow Water each received

30%

equity interests for an aggregate

$150,000

investment.

We account for our investment in the joint venture under the equity method of accounting. We have determined that while we have significant influence over the joint venture through our technology license and our position on the Board of Directors, we do

not

control the joint venture or are otherwise involved in managing the entity and we own less than a majority of the equity. Therefore, we record the asset on our consolidated balance sheet and record an increase or decrease the recorded balance by our percentage ownership of the profits or losses in the joint venture. During the

nine

months ended

September 30, 2020,

the joint venture incurred a loss and our

40%

ownership share reduced our investment interest by

$27,000.

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the

three

and

nine

months ended

September 30, 2019

and

2020,

the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company's net loss.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, debt transactions, derivative liabilities, allowance for bad debt, asset depreciation and amortization, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-Based Compensation Expense

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Fair value is determined on the grant date. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model.

For stock and stock options issued to consultants and other non-employees for services, the Company measures and records an expense as of the earlier of the date at which either: a commitment for performance by the non-employee has been reached or the non-employee's performance is complete. The equity instruments are measured at the current fair value, and for stock options, the instruments are measured at fair value using the Black Scholes option model.

The following methodology and assumptions were used to calculate share-based compensation for the

three

and

nine

months ended

September 30, 2019

and

2020:

	2019						2020
	Non Plan			2018 Plan			Non Plan			20 18 Plan
Risk free interest rate	2.00	–	2.65%	2.0	–	2.65%	0.66	–	1.02%	0.64	–	1.90%
Expected volatility	147	–	152%	147	–	152%	129	–	131%	126	–	133%
Expected dividend yield		—			—			—			—
Forfeiture rate		—			—			—			—
Life in years		10			10			10			10

Expected price volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Expected volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility.

The risk-free interest rate used in the Black-Scholes calculation is based on the prevailing U.S. Treasury yield as determined by the U.S. Federal Reserve. We have never paid any cash dividends on our common stock and do

not

anticipate paying cash dividends on our common stock in the foreseeable future.

Historically, we have

not

had significant forfeitures of unvested stock options granted to employees and Directors. A significant number of our stock option grants are fully vested at issuance or have short vesting provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock options as

zero

.

Warrants

Warrants issued with our convertible promissory notes, note payables, and lines of credit, are accounted for under the fair value and relative fair value method. The warrant is

first

analyzed per its terms as to whether it has derivative features or

not.

If the warrant is determined to be a derivative and

not

qualify for equity treatment, then it is measured at fair value using the Black Scholes option model, and recorded as a liability on the balance sheet. The warrant is re-measured at its then current fair value at each subsequent reporting date (it is “marked-to-market”). If the warrant is determined to

not

have derivative features, it is recorded into equity at its fair value using the Black Scholes option model, however, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the convertible note.

The convertible note issued with the warrant is recorded at its fair value, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the warrant. Further, the convertible promissory note is examined for any intrinsic beneficial conversion feature (“BCF”) of which the convertible price of the note is less than the closing common stock price on date of issuance. If the relative fair value method is used to value the convertible promissory note and there is an intrinsic BCF, a further analysis is undertaken of the BCF using an effective conversion price which assumes the conversion price is the relative fair value divided by the number of shares the convertible debt is converted into by its terms. The BCF value is accounted for as equity.

The warrant and BCF relative fair values are also recorded as a discount to the convertible promissory notes.

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue Recognition

We account for revenue in accordance with ASC

606,

“revenue from Contacts with Customers”. The guidance focuses on the core principle for revenue recognition, which is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, the guidance provides that an entity should apply the following steps:

Step

1:

Identify the contract(s) with a customer.

Step

2:

Identify the performance obligations in the contract.

Step

3:

Determine the transaction price.

Step

4:

Allocate the transaction price to the performance obligations in the contract.

Step

5:

Recognize revenue when (or as) the entity satisfies a performance obligation.

We have revenue from

four

subsidiaries, ONM, BLEST, BioLargo Water, and Clyra. ONM, BioLargo Water, and Clyra identify its contract with the customer through a written purchase order, in which the details of the contract are defined including the transaction price and method of shipment. The only performance obligation is to create and ship the product and each product has separate pricing. Revenue is recognized at a point in time when the order for its goods are shipped if its agreement with the customer is FOB manufacturer, and when goods are delivered to its customer if its agreement with the customer is FOB destination. Revenue is recognized with a reduction for sales discounts, as appropriate and negotiated in the customer's purchase order. ONM also installs misting systems for which it bills on a time and materials basis. It identifies its contract with the customer through a written purchase order in which the details of the time to be billed and materials purchased and an estimated completion date. The performance obligation is the completion of the installation. Revenue is recognized over time as the work is performed.

BLEST identifies services to be performed in a written contract, which specifies the performance obligations and the rate at which the services will be billed. Each service is separately negotiated and priced. Revenue is recognized as services are performed and completed. BLEST's contracts typically call for invoicing for time and materials incurred for that contract. A few contracts have called for milestone or fixed cost payments, where BLEST invoices an agreed-to amount per month for the life of the contract. In these instances, completed work, billed hourly, is recognized as revenue. If the billing amount is greater or lesser than the completed work, a receivable or payable is created. These accounts are adjusted upon additional billings as the work is completed. To date, there have been

no

discounts or other financing terms for the contracts.

In the event that we generate revenues from royalties or license fees from our intellectual property, we anticipate a licensee would pay a license fee in

one

or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. Upon entering into a licensing agreement, we will determine the appropriate method of recognizing the royalty and license fees.

Government Grants

We have been awarded multiple research grants from governmental and quasi-governmental institutions. The grants received are considered “other income” and are included in our Consolidated Statements of Operations. We received our

first

grant in

2015

and have been awarded over

80

 grants totaling over

$3.7

million. Some of the funds from these grants are given directly to

third

parties (such as the University of Alberta or a

third

-party research scientist) to support research on our technology. The grants have terms generally ranging between

nine

and

eighteen

months and support a majority, but

not

all, of the related research budget costs. This cooperative research allows us to utilize (i) a depth of resources and talent to accomplish highly skilled work, (ii) financial aid to support research and development costs, (iii) independent and credible validation of our technical claims.

The grants typically provide for (i) recurring monthly amounts, (ii) reimbursement of costs for research talent for which we invoice to request payment, and (iii) ancillary cost reimbursement for research talent travel related costs. All awarded grants have specific requirements on how the money is spent, typically to employ researchers.

None

of the funds

may

be used for general administrative expenses or overhead in the United States. These grants have substantially increased our level of research and development activities in Canada. We continue to apply for Canadian government and agency grants to fund research and development activities. There was

no

grant income for the

three

months ended

September 30, 2020.

Not

all of our grant applications have been awarded, and

no

assurance can be made that any pending grant application, or any future grant applications, will be awarded.

Fair Value of Financial Instruments

Management believes the carrying amounts of the Company's financial instruments (excluding debt and equity instruments) as of

December 31, 2019,

and

September 30, 2020,

approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, lines of credit, and other assets and liabilities.

Lincoln Park

During the

three

months ended

March 31, 2020,

pursuant to our

August 2017

agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”), we elected to sell to Lincoln Park

1,398,223

shares of our common stock, for which we received

$295,000

in gross and net proceeds. Additionally, we issued Lincoln Park

14,420

“additional commitment” shares required under the agreement. We did

not

sell any shares to Lincoln Park during the

three

and

nine

months ended

September 30, 2019.

In conjunction with the signing of the

March 2020

agreement with Lincoln Park (see below), we recorded the remaining deferred offering costs on our

August 2017

agreement totaling

$122,000

as additional paid in capital on our consolidated balance sheet.

On

March 30,

, 

2020,

we entered into a Purchase Agreement with Lincoln Park, pursuant to which Lincoln Park agreed to purchase from us at our request up to an aggregate of

$10,250,000

of our common stock (subject to certain limitations) from time to time over a period of

three

years. The agreement allows us, at our sole discretion, to direct Lincoln Park to purchase shares of our common stock, subject to limitations in both volume and dollar amount. The purchase price of the shares that

may

be sold to Lincoln Park under the Purchase Agreement is the lower of (i) the lowest sale price on the date of purchase, or (ii) the average of the

three

lowest closing prices in the prior

12

business days. There are

no

restrictions on future financings, rights of

first

refusal, participation rights, penalties or liquidated damages other than a prohibition on entering into a “Variable Rate Transaction,” as defined in the agreement. Lincoln Park

may

not

assign or transfer its rights and obligations under the Purchase Agreement. This agreement replaced the

August 2017

agreement with Lincoln Park. Concurrently with the Purchase Agreement, we entered into a Registration Rights Agreement, pursuant to which we filed a registration statement on Form S-

1

with the SEC on

April 10, 2020.

This registration statement was declared effective on

April 21, 2020,

and as of

April 29, 2020,

we commenced regular purchases under the agreement.

In the

March 30, 2020

agreement, we agreed to issue

2,928,571

shares to Lincoln Park as a commitment fee, valued at

$527,000

and recorded as additional paid in capital on our consolidated balance sheet as of

March 31, 2020.

Additionally, the Purchase Agreement provided for an initial sale of

1,785,715

shares to Lincoln Park for

$250,000.

We received those funds and issued the shares on

March 31, 2020.

Since inception of the

Vista Capital)

On

January 7, 2019,

Vista Capital Investments LLC (“Vista Capital”) invested

$300,000

and in exchange we issued a convertible promissory note in the principal amount of

$330,000.

Originally set to mature

nine

months from the date of issuance, the maturity date was extended multiple times. The note earned a

one

-time interest charge of

12%,

which was recorded as a discount on convertible notes and was amortized over the term of the note. The note allowed conversion of the note into our common stock at a price equal to

65%

of the lowest closing bid price of the Company's common stock during the

25

consecutive trading days immediately preceding the conversion date. The intrinsic value of the beneficial conversion feature resulted in a fair value totaling

$300,000,

and is recorded as a discount on convertible notes on our balance sheet. This discount was amortized over the term of the note as interest expense, all of which was recorded in

2019.

During the

three

months ended

March 31, 2020,

Vista Capital elected to convert the remaining balance of

$270,000

of the outstanding principal and interest due on the note, and we issued

2,417,059

shares of our common stock.

Convertible Twelve-month OID notes

From

June 7, 2019

through

September 30, 2019,

we received

$2,235,000

and issued convertible promissory notes (each, a “Twelve-Month OID Note”) in the aggregate principal amount of

$2,794,000,

with a

25%

original issue discount, to

34

accredited investors. The original issuance discount totaled

$559,000

and is recorded as a discount on convertible notes payable on our balance sheet. The intrinsic value of the beneficial conversion features resulted in an aggregate fair value of

$2,235,000,

and is recorded as a discount on convertible notes on our balance sheet. The discounts were amortized and recorded to interest expense over the term of the notes. These notes each mature

twelve

months from the date of issuance.

During the

three

months ended

September 30, 2019,

in exchange for

$305,000

of convertible note payables that were coming due, we issued an additional

$381,000

in Twelve-Month OID Notes, with a

25%

original issue discount. The original issue discount totaled

$76,000

and is recorded as a discount on convertible notes payable on our balance sheet. The intrinsic value of the beneficial conversion features resulted in an aggregate fair value of

$381,000

and is recorded as debt extinguishment expense on our statement of operations. The discount will be amortized and recorded to interest expense over the term of the notes. These notes mature

twelve

months from the date of issuance.  

Each Twelve-month OID Note is convertible by the investor at any time at

$0.17

per share. The notes earn interest at a rate of

five

percent (

5%

) per annum, due at maturity. At the maturity of each note, the Company exercised its right to redeem the notes through the issuance of common stock at a conversion price equal to the lower of the “conversion price” (initially

$0.17,

as

may

be adjusted), and

70%

of the lowest daily volume weighted average price of the Company's common stock during the

25

trading days preceding the conversion date. During the

nine

months ended

September 30, 2020,

$3,112,000

of the remaining outstanding principal of

12

-Month OID Notes was converted, and we issued

30,208,453

shares of our common stock. Of that amount,

1,415,221

shares were issued as payment for interest due on the notes.

Note Maturity Extensions

On

August 10, 2020,

we and the holder of a convertible promissory note in the principal amount of

$475,000

due

August 12, 2020,

entered into an agreement to extend the maturity date of the note to

August 12, 2021.

As consideration for the extension of the maturity date, we agreed to lower the conversion price from

$0.17

to

$0.14,

we agreed extend the expiration date from

September 18, 2023

to

September 18, 2025,

of

a

a

warrant to purchase

2,095,588

shares of common stock. The fair value of the reduced conversion price and extended warrant expirations dates resulted in a fair value totaling

$228,000,

recorded as a loss on extinguishment on our statement of operations. The noteholder then converted

$119,000

of principal into

848,214

shares of common stock and

$24,000

may

be made under this plan for a period of

The plan authorizes the following types of awards: (i) incentive and non-qualified stock options, (ii) restricted stock awards, (iii) stock bonus awards, (iv) stock appreciation rights, (v) restricted stock units, and (vi) performance awards. The total number of shares reserved and available for awards pursuant to this Plan as of the date of adoption of this

2018

Plan by the Board is

40

million shares. The number of shares available to be issued under the

2018

Plan increases automatically each

Fair Value – Interest Expense

To determine interest expense related to our outstanding warrants issued in conjunction with debt offerings, the fair value of each award grant is estimated on the date of grant using the Black-Scholes option pricing model and the relative fair values are amortized over the life of the warrant. For the determination of expense of warrants issued for services, extinguishment of debt and settlement management also uses the option-pricing model. The principal assumptions we used in applying this model were as follows:

	September 30, 2019			September 30, 2020
Risk free interest rate	1.42	–	2.62%	0.15	–	0.23%
Expected volatility	86	–	110%	100	–	112
Expected dividend yield		—			—
Forfeiture rate		—			—
Expected life in years	2	–	5	0.33	–	5

The risk-free interest rate is based on U.S. Treasury yields in effect at the time of grant. Expected volatilities are based on historical volatility of our common stock. The expected life in years is based on the contract term of the warrant.

Acquisition of In-process Research and Development

On

September 26, 2018,

Clyra Medical entered into a transaction with Scion Solutions, LLC, for the purchase of its intellectual property, including its SkinDisc. The consideration provided to Scion is subject to an escrow agreement (“Escrow Agreement”) and earn out provisions and includes: (i)

21,000

shares of the Clyra Medical common stock; (ii)

10,000

shares of Clyra Medical common stock redeemable for

7,142,858

BioLargo common shares held by Clyra Medical; and (iii) a promissory note in the principal amount of

$1,250,000

to be paid through new capital investments and revenue, as detailed below. This consideration was initially held in escrow pending Clyra Medical raising

$1

million “base capital” to fund its business operations.

On

December 17, 2018,

the parties entered into a closing agreement (“Closing Agreement”) reflecting the satisfaction of the obligation to raise

$1

million “base capital”; at that time,

one

-half of the shares of Clyra Medical common stock exchanged for the Scion assets were released to Scion. The remaining Clyra Medical common shares (a total of

15,500

shares) remain subject to the Escrow Agreement's performance metrics, each vesting

one

-

fifth

of the remaining shares of common stock (e.g.,

2,000

shares of Clyra common stock, and an additional

1,100

shares redeemable for

785,714

BioLargo shares): (a) notification of FDA premarket clearance of certain orthopedics products, or recognition by Clyra Medical of

$100,000

gross revenue; (b) the recognition by Clyra Medical of

$100,000

in aggregate gross revenue; (c) the granting of all or any part of the patent application for the SkinDisc product, or recognition by Clyra Medical of

$500,000

in gross revenue; (d) recognition by Clyra Medical of

$1

million in aggregate gross revenue; and (e) recognition by Clyra Medical of

$2

million in gross revenue.

During the

three

months ended

September 30, 2020,

Clyra gross revenue exceeded

$100,000,

and thus the

first

performance metric was met. As a result, Scion vested

3,100

common shares. The fair value of the shares vested total

$128,000

and was recorded on our balance sheet as In-Process Research and Development, and Liability to Clyra Medical Shareholder.

Scion Solutions – Note Payable and Clyra Liability

The promissory note in the principal amount of

$1,250,000

issued by Clyra Medical to Scion on

September 26, 2018 (

“Clyra-Scion Note”) accrues interest at the rate of

5%.

Principal and interest due under the note are to be paid periodically at a rate of

25%

of investment proceeds received by Clyra Medical. At the initial maturity of

June 17, 2020,

the maturity date of the note automatically extended for

12

months and will continue to automatically extend for additional

12

-month periods until the note is repaid in full. Clyra is required to make annual payments on the note in an amount equal to the greater of (i)

25%

of investment proceeds received during the

12

-month period, and (ii)

5%

of Clyra Medical's gross revenues.

At

September 30, 2020,

the balance due on the Clyra-Scion Note equaled

$1,007,000.

The shares of BioLargo common stock held by Clyra for the benefit of Scion (the redemption shares) totals

$771,000

and is recorded on our balance sheet as a liability to “Clyra Medical Shareholder”.

Inventory Line of Credit

On

June 30, 2020,

Clyra entered into a Revolving Line of Credit Agreement whereby Vernal Bay Capital Group, LLC committed to provide a

$1,000,000

inventory line of credit to Clyra, with a

first

draw of

$200,000

received

July 6, 2020.

Clyra is required to use funds from the line of credit to manufacture inventory. Additional draws are conditional upon Clyra presenting invoices or purchase orders to the lender equal to the greater of

one

-half of principal outstanding on the line of credit, and

$200,000.

The line of credit note earns interest at

15%,

matures in

one

year, and requires Clyra pay interest and principal from gross product sales. For the

first

180

days, on a monthly basis, Clyra is required to pay

30%

of gross product sales to reduce amounts owed, and thereafter

60%

of gross sales. Clyra issued Vernal Bay

323

shares of its common stock as a commitment fee for the line of credit, valued at

$100,000.

A security agreement of the same date grants Vernal Bay a security interest in Clyra's inventory, as that term is defined in the Uniform Commercial Code. Clyra

may

prepay the note at any time.

Clyra has received a

second

draw under this line of credit (see Note

12

).

Clyra Financing

During the

nine

months ended

September 30, 2020,

Clyra sold

2,742

shares of its common stock at

$310

per Clyra share.

During

June 2020,

BioLargo increased its investment in Clyra by

23,004

shares. Of this amount,

22,513

shares were issued to BioLargo pursuant to an amendment to the BioLargo/Clyra license agreement whereby BioLargo has granted Clyra rights to commercialize its technology in certain medical fields. The amendment provided, among other things, for the payment of the “initial license fee” through the issuance of

22,513

shares of Clyra common stock. (See Note

the Company had issued options to purchase

7,624

three

and

nine

months ended

September 30, 2020,

Clyra issued options to purchase

645

and

2,685

shares of Clyra Medical common stock. Each option issued has an exercise price of

$1.00

10

years from the date of grant. The fair value of the options issued in the

three

and

nine

months ended

September 30, 2020,

totaled

$140,000

and

$580,000,

respectively, and the additional fair value totaling

$214,000

was recorded as a loss on extinguishment of debt in our consolidated statement of operations. We used the Black-Scholes model to calculate the initial fair value, assuming a stock price on date of grant of

$310

per share. Because Clyra is a private company with

no

secondary market for its common stock, the resulting fair value was discounted by

30%.

Consulting Agreement

Clyra entered into a consulting agreement with Beach House Consulting, LLC, through which Jack B. Strommen will be providing consulting services to Clyra related to its sales and marketing activities, and in exchange receive

$23,000

four

years. On

June 30, 2020,

at Clyra's request, Beach House Consulting agreed to accept

3,639

shares of Clyra common stock as full payment of the consulting fee, in lieu of cash. The obligation to provide the consulting services is dependent on Clyra generating an average of

$250,000

in monthly sales over

three

consecutive months. The value of the shares issued to Beach House is recorded as a prepaid asset (see Note

Wholly-Owned Subsidiary [Text Block]

Note

9.

BioLargo Engineering, Science and Technologies, LLC

In

September 2017,

we commenced a full-service environmental engineering firm and formed a Tennessee entity named BioLargo Engineering, Science & Technologies, LLC (“BLEST”). In conjunction with the start of this subsidiary, we entered into a

three

-year office lease in the Knoxville, Tennessee area (since extended), and entered into employment agreements with

six

scientists and engineers. The company was capitalized with

two

classes of membership units: Class A,

100%

owned by Biolargo, and Class B, held by management of BLEST, and which initially had

no

“profit interest,” as that term is defined in Tennessee law. However, over the succeeding

five

years, the Class B members can earn up to a

30%

profit interest. They were also granted options to purchase up to an aggregate

1,750,000

shares of BioLargo, Inc. common stock. The profit interest and option shares are subject to a

five

year vesting schedule tied to the performance of the subsidiary, including gross revenue targets that increase over time, obtaining positive cash flow by

March 31, 2018 (

which was

not

met), collecting

90%

of its account receivables, obtaining a profit of

10%

in its

first

year (and increasing in subsequent years), making progress in the scale-up and commercialization of our AOS system, and using BioLargo research scientists (such as our Canadian team) for billable work on client projects. These criteria are to be evaluated annually by BLEST's compensation committee (which includes BioLargo's president, CFO, and BLEST's president), beginning

September 2018.

Given the significant performance criteria, the Class B units and the stock options will only be recognized in compensation expense if or when the criteria are satisfied.

Since the commencement of operations, the Compensation Committee has met twice, once in

September 2018,

and once in

November 2019.

In

2018,

it reviewed the operating performance and determined that the performance metrics were

not

met and as a result, did

not

award any Class B units or stock options. The Committee decided to roll forward

one

additional year to the time allowed for the performance metrics to be met and for the Class B units and stock options to be awarded.

In

November 2019,

the Compensation Committee again reviewed the operating performance and determined that a portion of the performance metrics were met. It was agreed that

one

-half of the eligible profits interests would be vested (

2.5%

in the aggregate). The fair value of the profit interest was nominal and

not

recorded. Nevertheless, Biolargo treats the

2.5%

profits interest as part of the noncontrolling interest on both the balance sheet and the statement of operations.

Business Segment Information

BioLargo currently has

four

operating business segments, plus its corporate entity which is responsible for general corporate operations, including administrative functions, finance, human resources, marketing, legal, etc. The

four

operational business segments are:

1. ONM Environmental (formerly Odor- No -More) (“ONM”) -- which sells odor and volatile organic control products and services (located in Westminster, California);

2. Clyra Medical Technologies (“Clyra Medical”) -- which develops and sells medical products based on our technologies, including Clyraguard Personal Protective Spray;

3. BLEST -- which provides professional engineering services on a time and materials basis for outside clients and supports our internal operations as needed (located in Oak Ridge, Tennessee); and

4. BioLargo Water (“Water”) -- which historically focused entirely on R&D, and has now shifted its focus to commercializing the AOS technology, developing manufacturing operations for hand sanitizers and supporting the development of iodine based disinfecting products for the company (located in Edmonton, Alberta Canada).

Historically,

none

of our operating business units have operated at a profit and therefore each required additional cash to meet its monthly expenses. The additional sources of the cash to fund the shortfall from operations of ONM, BLEST and BioLargo Water have been provided by BioLargo's sales of debt or equity, research grants, and tax credits. Clyra Medical has been funded by

third

party investors who invest directly in Clyra Medical in exchange for equity ownership in that entity.

COVID-

19

On

March 11, 2020,

the World Health Organization declared the outbreak of Coronavirus Disease

2019

(“COVID-

19”

or “virus”) as a global pandemic. The full impact of COVID-

19

is unknown and rapidly evolving. The outbreak and any preventative or protective actions that the Company or its customers

may

take in respect of this virus

may

result in a period of disruption, including the Company's financial reporting capabilities or its operations generally, and could potentially impact the Company's customers and other

third

parties. Any resulting financial impact cannot be reasonably estimated at this time, but

may

materially affect the business and the Company's financial condition and results of operations. The extent to which the COVID-

19

impacts the Company's results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which

may

emerge concerning the severity of COVID-

19

and the actions to contain the virus or treat its impact, among others. The Company has been operating remotely without any significant disruption of operations, although its clients have been disrupted. The Company is currently evaluating the impact, if any, on its financial statements, and has

not

yet quantified what material impacts to the financial statements

may

result from the actions taken by the Company and its customers in respect of this virus.

Office Leases

We have long-term operating leases for office, industrial and laboratory space in Westminster, California, Oak Ridge, Tennessee, and Alberta, Canada. Payments made under operating leases are charged to the Consolidated Statement of Operations and Comprehensive Loss on a straight-line basis over the term of the operating lease agreement. For the

nine

months ended

September 30, 2019

and

2020,

rental expense was

$156,000

and

$167,000,

respectively.  On

January 1, 2019,

we adopted ASC

842

which resulted in a right-of-use asset and lease liability. Short-term leases are

not

included in our analysis. The adoption resulted in an immaterial cumulative effect of an accounting change that was

not

recorded.  The lease of our Westminster facility qualifies for the new treatment; it originated in

August 2016,

was originally scheduled to expire

August 2020,

contains a yearly escalation of

3%,

and includes a

four

-year renewal option whereby the base rent is adjusted to then market value. We exercised our option to extend the lease for

four

years. It is too early for management to determine if it will extend another

four

years, therefore the additional

four

-year extension is

not

included in the analysis. The lease of our Oak Ridge, Tennessee facility also qualifies, and it had

one

executed extension to

September 2022,

and has

one

renewal option for another

five

years where the rental rate would adjust to greater of the current price and fair market value.

No

determination has been made whether to exercise the renewal option for the Oak Ridge facility. The lease of our Canadian facility is less than

one

year.

None

of our leases have additional terms related to the payments or mechanics of the lease: there are

not

any common area maintenance charges or tax sharing arrangements, easement provisions or any free rent. Since there is

no

explicit interest rate in leases, management used its incremental borrowing rate, which is estimated to be

18%.

As of

September 30, 2020,

our weighted average remaining lease term is

three

years and the total remaining operating lease payments is

$578,000.

Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2020

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, and its wholly- and partially-owned subsidiaries, including Clyra Medical. Management believes Clyra Medical's financial statements are appropriately consolidated with that of the Company after reviewing the guidance of ASC Topic 

810

,

 “Consolidation”, and concluding that BioLargo controls Clyra Medical. While BioLargo does

not

have voting interest control through a majority stock ownership of Clyra Medical (it owns

47%

of the outstanding voting stock), it does exercise control under the “Variable Interest Model”: there is substantial board overlap, BioLargo is the primary beneficiary since it has the power to direct Clyra Medical's activities that most significantly impact Clyra Medical's performance, and it has the obligation to absorb losses or receive benefits (through royalties and licensing) that could be potentially significant to Clyra Medical. BioLargo has consolidated Clyra Medical's operations for all periods presented. (See Note

8.

)

All intercompany accounts and transactions have been eliminated. 

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency

The Company has designated the functional currency of BioLargo Water, Inc., our Canadian subsidiary, to be the Canadian dollar. Therefore, translation gains and losses resulting from differences in exchange rates are recorded in accumulated other comprehensive income.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of

three

-months or less when acquired to be cash equivalents. Substantially all cash equivalents are held in short-term money market accounts at

one

of the largest financial institutions in the United States. From time to time, our cash account balances are greater than the Federal Deposit Insurance Corporation insurance limit of

$250,000

per owner per bank, and during such times, we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the financial institution. We do

not

anticipate non-performance by our financial institution.

Receivable [Policy Text Block]

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts as of 

December 31, 2019 

was

$24,000

and

September 30, 2020

was 

$35,000.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Credit Concentration

We have a limited number of customers that account for significant portions of our revenue. For the

nine

months ended

September 30, 2019

and

2020,

each period had

two

customers that accounted for

10%

or more of our consolidated revenues, as follows:

	September 30 , 2019			September 30 , 2020
Customer A	<10		%		12	%
Customer B		13	%	<10		%
Customer C		10	%	<10		%

We had

two

customers that accounted for more than

10%

of consolidated accounts receivable at

December 31, 2019

and

three

customers that accounted for more than

10%

of consolidated accounts receivable at

September 30, 2020,

as follows:

	December 31, 2019			September 30 , 2020
Customer A	<20		%		15	%
Customer D	<10		%		15	%
Customer E	<10		%		10	%
Customer F		14	%	<10		%
Customer G		13	%	<10		%

Inventory, Policy [Policy Text Block]

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. The allowance for obsolete inventory as of 

December 31, 2019

and

September 30, 2020

was

$3,000

.

 As of

December 31, 2019,

and

September 30, 2020,

inventories consisted of (in thousands):

	December 31, 2019		September 30 , 2020
Raw material	$	11	$	180
Finished goods		5		112
Total	$	16	$	292

Other Assets, Policy [Policy Text Block]

Other Non-Current Assets

Other non-current assets consisted of (i) security deposits of

$35,000

related to our business offices, and (ii) prepaid consulting fees from the issuance of Clyra Medical stock, resulting in a fair value of

$787,500

(see Note

8

).

Lessee, Leases [Policy Text Block]

Leases

In

February 2016,

the FASB issued ASU Update

No.

2016

-

02,

“Leases,” which requires lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability, and lessors to recognize a net lease investment. Additional qualitative and quantitative disclosures are also required. We adopted this standard effective

January 1, 2019

using the effective date option, which resulted in a

$399,000

gross up of assets and liabilities; this balance

may

fluctuate over time as we enter into new leases, extend or terminate current leases. Upon the transition to the ASC

842,

the Company elected to use hindsight as a practical expedient with respect to determining the lease terms (as we considered our updated expectations of acceptance of the Westminster California facility lease renewal) and in assessing any impairment of right-of-use assets for existing leases.

No

impairment is expected at this time. As of

September 30, 2020,

the right-of-use assets on our balance sheet related to our operating leases totals

$356,000.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment

Long-lived and definite lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset

may

not

be recoverable. If the sum of the expected future undiscounted cash flows from the use of the asset and its eventual disposition is less than the carrying amount of the asset, then an impairment loss is recognized. The impairment loss is measured based on the fair value of the asset. Any resulting impairment is recorded as a reduction in the carrying value of the related asset in excess of fair value and a charge to operating results. As of

September 30, 2019

and

2020,

management determined that there was

no

impairment of its long-lived assets, including its In-process Research and Development at Clyra Medical (see Note

8

).

Equity Method Investments [Policy Text Block]

Equity

Method of

Accounting

On

March 20, 2020,

we invested

$100,000

into a South Korean entity (Odin Co. Ltd., “Odin”) pursuant to a Joint Venture agreement we had entered into with BKT Co. Ltd. and its U.S. based subsidiary, Tomorrow Water. We received a

40%

non-dilutive equity interest, and BKT and Tomorrow Water each received

30%

equity interests for an aggregate

$150,000

investment.

We account for our investment in the joint venture under the equity method of accounting. We have determined that while we have significant influence over the joint venture through our technology license and our position on the Board of Directors, we do

not

control the joint venture or are otherwise involved in managing the entity and we own less than a majority of the equity. Therefore, we record the asset on our consolidated balance sheet and record an increase or decrease the recorded balance by our percentage ownership of the profits or losses in the joint venture. During the

nine

months ended

September 30, 2020,

the joint venture incurred a loss and our

40%

ownership share reduced our investment interest by

$27,000.

Earnings Per Share, Policy [Policy Text Block]

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the

three

and

nine

months ended

September 30, 2019

and

2020,

the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company's net loss.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, debt transactions, derivative liabilities, allowance for bad debt, asset depreciation and amortization, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-based Payment Arrangement [Policy Text Block]

Share-Based Compensation Expense

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Fair value is determined on the grant date. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model.

For stock and stock options issued to consultants and other non-employees for services, the Company measures and records an expense as of the earlier of the date at which either: a commitment for performance by the non-employee has been reached or the non-employee's performance is complete. The equity instruments are measured at the current fair value, and for stock options, the instruments are measured at fair value using the Black Scholes option model.

The following methodology and assumptions were used to calculate share-based compensation for the

three

and

nine

months ended

September 30, 2019

and

2020:

	2019						2020
	Non Plan			2018 Plan			Non Plan			20 18 Plan
Risk free interest rate	2.00	–	2.65%	2.0	–	2.65%	0.66	–	1.02%	0.64	–	1.90%
Expected volatility	147	–	152%	147	–	152%	129	–	131%	126	–	133%
Expected dividend yield		—			—			—			—
Forfeiture rate		—			—			—			—
Life in years		10			10			10			10

Expected price volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Expected volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility.

The risk-free interest rate used in the Black-Scholes calculation is based on the prevailing U.S. Treasury yield as determined by the U.S. Federal Reserve. We have never paid any cash dividends on our common stock and do

not

anticipate paying cash dividends on our common stock in the foreseeable future.

Historically, we have

not

had significant forfeitures of unvested stock options granted to employees and Directors. A significant number of our stock option grants are fully vested at issuance or have short vesting provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock options as

zero

.

Warrant Policy [Policy Text Block]

Warrants

Warrants issued with our convertible promissory notes, note payables, and lines of credit, are accounted for under the fair value and relative fair value method. The warrant is

first

analyzed per its terms as to whether it has derivative features or

not.

If the warrant is determined to be a derivative and

not

qualify for equity treatment, then it is measured at fair value using the Black Scholes option model, and recorded as a liability on the balance sheet. The warrant is re-measured at its then current fair value at each subsequent reporting date (it is “marked-to-market”). If the warrant is determined to

not

have derivative features, it is recorded into equity at its fair value using the Black Scholes option model, however, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the convertible note.

The convertible note issued with the warrant is recorded at its fair value, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the warrant. Further, the convertible promissory note is examined for any intrinsic beneficial conversion feature (“BCF”) of which the convertible price of the note is less than the closing common stock price on date of issuance. If the relative fair value method is used to value the convertible promissory note and there is an intrinsic BCF, a further analysis is undertaken of the BCF using an effective conversion price which assumes the conversion price is the relative fair value divided by the number of shares the convertible debt is converted into by its terms. The BCF value is accounted for as equity.

The warrant and BCF relative fair values are also recorded as a discount to the convertible promissory notes.

Non Cash Transactions [Policy Text Block]

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue from Contract with Customer [Policy Text Block]

Revenue Recognition

We account for revenue in accordance with ASC

606,

“revenue from Contacts with Customers”. The guidance focuses on the core principle for revenue recognition, which is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, the guidance provides that an entity should apply the following steps:

Step

1:

Identify the contract(s) with a customer.

Step

2:

Identify the performance obligations in the contract.

Step

3:

Determine the transaction price.

Step

4:

Allocate the transaction price to the performance obligations in the contract.

Step

5:

Recognize revenue when (or as) the entity satisfies a performance obligation.

We have revenue from

four

subsidiaries, ONM, BLEST, BioLargo Water, and Clyra. ONM, BioLargo Water, and Clyra identify its contract with the customer through a written purchase order, in which the details of the contract are defined including the transaction price and method of shipment. The only performance obligation is to create and ship the product and each product has separate pricing. Revenue is recognized at a point in time when the order for its goods are shipped if its agreement with the customer is FOB manufacturer, and when goods are delivered to its customer if its agreement with the customer is FOB destination. Revenue is recognized with a reduction for sales discounts, as appropriate and negotiated in the customer's purchase order. ONM also installs misting systems for which it bills on a time and materials basis. It identifies its contract with the customer through a written purchase order in which the details of the time to be billed and materials purchased and an estimated completion date. The performance obligation is the completion of the installation. Revenue is recognized over time as the work is performed.

BLEST identifies services to be performed in a written contract, which specifies the performance obligations and the rate at which the services will be billed. Each service is separately negotiated and priced. Revenue is recognized as services are performed and completed. BLEST's contracts typically call for invoicing for time and materials incurred for that contract. A few contracts have called for milestone or fixed cost payments, where BLEST invoices an agreed-to amount per month for the life of the contract. In these instances, completed work, billed hourly, is recognized as revenue. If the billing amount is greater or lesser than the completed work, a receivable or payable is created. These accounts are adjusted upon additional billings as the work is completed. To date, there have been

no

discounts or other financing terms for the contracts.

In the event that we generate revenues from royalties or license fees from our intellectual property, we anticipate a licensee would pay a license fee in

one

or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. Upon entering into a licensing agreement, we will determine the appropriate method of recognizing the royalty and license fees.

Government Grants [Policy Text Block]

Government Grants

We have been awarded multiple research grants from governmental and quasi-governmental institutions. The grants received are considered “other income” and are included in our Consolidated Statements of Operations. We received our

first

grant in

2015

and have been awarded over

80

 grants totaling over

$3.7

million. Some of the funds from these grants are given directly to

third

parties (such as the University of Alberta or a

third

-party research scientist) to support research on our technology. The grants have terms generally ranging between

nine

and

eighteen

months and support a majority, but

not

all, of the related research budget costs. This cooperative research allows us to utilize (i) a depth of resources and talent to accomplish highly skilled work, (ii) financial aid to support research and development costs, (iii) independent and credible validation of our technical claims.

The grants typically provide for (i) recurring monthly amounts, (ii) reimbursement of costs for research talent for which we invoice to request payment, and (iii) ancillary cost reimbursement for research talent travel related costs. All awarded grants have specific requirements on how the money is spent, typically to employ researchers.

None

of the funds

may

be used for general administrative expenses or overhead in the United States. These grants have substantially increased our level of research and development activities in Canada. We continue to apply for Canadian government and agency grants to fund research and development activities. There was

no

grant income for the

three

months ended

September 30, 2020.

Not

all of our grant applications have been awarded, and

no

assurance can be made that any pending grant application, or any future grant applications, will be awarded.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial Instruments

Management believes the carrying amounts of the Company's financial instruments (excluding debt and equity instruments) as of

December 31, 2019,

and

September 30, 2020,

approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, lines of credit, and other assets and liabilities.
