The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and the related notes to the consolidated financial statements included elsewhere in this report.

This discussion contains forward-looking statements that involve risks and uncertainties. Such statements, which include statements concerning future revenue sources and concentration, selling, general and administrative expenses, research and development expenses, capital resources, additional financings and additional losses, are subject to risks and uncertainties, including, but not limited to, those discussed above in Part I, Item 1 and elsewhere in this Annual Report, particularly in "Risk Factors," that could cause actual results to differ materially from those projected. The forward-looking statements set forth in this Annual Report are as of December 31, 2022, unless expressly stated otherwise, and we undertake no duty to update this information.

Results of Operations-Comparison of the years ended December 31, 2022 and 2021

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, which provides professional engineering services 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, which develops and sells medical products based on our
    technology;




  ? BioLargo Water, located in Edmonton, Alberta Canada, that has been
    historically pure research and development, and is now transitioning to focus
    on commercializing our AOS system; and

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



Our consolidated revenue for the year ended December 31, 2022 was $5,884,000, which is a 133% increase over the same period in 2021. Services revenue increased 53% ($491,000), while revenue from product sales increased by 182% ($2,862,000). The increase in service revenues was related to increased third-party client work by our subsidiary BLEST. The increase in product revenues was almost entirely due to an increase in the volume sales of private-label odor-control products, specifically the Pooph branded pet-odor product.





ONM Environmental



Our wholly-owned subsidiary ONM Environmental generates revenues through sales of our flagship product CupriDyne Clean, by providing design, installation, and maintenance services on the systems that deliver CupriDyne Clean at its clients' facilities, and through sales of private-label products based on our CupriDyne Clean technology.

Revenue (ONM Environmental)

ONM Environmental's revenues for the year ended December 31, 2022, were $4,374,000, an increase of $2,862,000 or 182% from the same period in 2021. The increase in revenues was almost entirely due to an increase in the volume of sales of private label odor-control products, specifically the Pooph branded pet-odor product (which increased by $2,712,000). Because ONM Environmental has no control over the marketing and sales activity or levels of Pooph, it cannot predict sales volumes related to it in future periods. Pooph management has indicated their intentions to continue their national advertising campaign as they place the product in national retail chains, including the introduction of the product in Walmart nationally. While they have performed well in the past, their execution of those future plans has inherent risks that are out of our control. (See the Risk Factor above titled "A significant portion of our revenue is concentrated with a select number of customers.")

Revenues from sales of industrial odor control products (e.g., CupriDyne Clean) were $1,190,000 for the year ended December 31, 2022, $1,000 less than the prior year.

Cost of Goods Sold (ONM Environmental)

ONM Environmental'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 Environmental's costs of goods decreased 2% in 2022 to 45%. The decrease was related to normal price fluctuations for raw materials and increased purchase volume.

Selling, General and Administrative Expense (ONM Environmental)

ONM Environmental's SG&A expenses were $1,276,000 in 2022, compared to $1,235,000 in 2021. We expect these expenses to remain flat in 2023.

Operating Income (ONM Environmental)

ONM Environmental generated operating income of $1,130,000 in 2022, compared to an operating loss of $511,000 in 2021. Provided that its private-label clients continue to increase their purchase of product, we expect this trend to continue.

BLEST (engineering division)





Revenue (BLEST)


BLEST generated $1,453,000 of revenue from third parties in 2022, compared to $961,000 in 2021, representing a 51% increase from the prior year. The increase is due to an increased number of client contracts, including those as a subcontractor for Bhate pursuant to which BLEST is providing services to U.S. Air Force bases.

In addition to providing service to third party clients, BLEST provides services to BioLargo and its subsidiaries for internal BioLargo projects. These services are billed internally, are considered intersegment revenue, and are eliminated in the consolidation of our financial statements. In the year ended December 31, 2022, it totaled $490,000, primarily used to further engineer and develop our flagship AOS water filtration system and our AEC PFAS treatment system. In addition, BLEST engineers are performing a critical role in the AOS pilot projects, some of which are supported by third-party research grants and has been instrumental in developing and supporting a professional engineered design service for misting systems being sold by our ONM operating unit.

Cost of Goods (Services) Sold (BLEST)

BLEST's cost of services includes employee labor, materials, as well as subcontracted labor costs. In 2022, its cost of services were 61% of its revenues, versus 69% in 2021. This decrease is due to contracts with better margins. We expect the cost of services to remain consistent in 2023 based on the contracts currently in progress.

Selling, General and Administrative Expense (BLEST)

BLEST SG&A expenses were $549,000 in 2022, compared to $411,000 in 2021, due to increased head-count related expenses. We expect these expenses to continue to increase in the current year as its revenues increase.





Operating Loss (BLEST)


BLEST had an operating loss of $452,000 in 2022, compared to an operating loss of $629,000 in 2021.

BLEST provides substantial support to BioLargo's other operations. While we are unable to record revenues generated from services by the engineering group to other BioLargo operating divisions for important projects such as the development of the AOS and AEC technologies, it is important to note that its net loss would be eliminated if it were selling these services to a third party at fair market value.

Because the subsidiary had a net loss, we invested cash during the year to allow it to maintain operations. BLEST's need for a cash subsidy to support its operations has decreased over time. We expect that in 2023 its sales and thus its gross profit will continue to increase. Our goal for this operation is that it produces a profit and contributes to corporate overhead in a significant way, although predicting when that will happen is difficult.

Selling, General and Administrative Expense - consolidated





Our Selling, General and Administrative expense ("SG&A") include both cash (for
example, salaries to employees) and non-cash expenses (for example, stock option
compensation expense). Our consolidated SG&A increased by 9% ($559,000) in the
year ended December 31, 2022, to $6,731,000. Our non-cash expenses (through the
issuance of stock and stock options) were $2,362,000 in 2022, compared with 2021
total of $2,241,000. The largest components of our SG&A expenses included (in
thousands):



                                 December 31, 2022       December 31, 2021
Salaries and payroll related   $             2,754     $             2,581
Professional fees                              629                     662
Consulting                                     867                     920

                                       28

--------------------------------------------------------------------------------

Table of Contents

Our salaries and payroll-related increased in the year ended December 31, 2022, primarily related to the implementation of a stock option bonus compensation program for employees and other related stock option compensation expenses, and also the hiring of additional personnel to support increasing operations. Office expense increased due to an increase in square footage of rented space and an increase in general office expenses related to expanded operations. Consulting expense decreased as we have reduced the use of consultants to identify business opportunities. The reduction in professional fees is largely due to the reduced use of outside legal counsel and other service providers. Board of director expense increased due to options issued to two new board members in November 2022, and replacement of expired options.





Impairment Expense


Impairment expense decreased by 42% for the year ended December 31, 2022, as compared with the year ended December 31, 2021, due to a one-time impairment expense related to the sale back to Scion Solutions, LLC ("Scion') of certain intellectual property, recorded on our balance sheet as "In-Process Research and Development" (see Note 9), recorded in the year ended December 31, 2021. During each of the years ended December 31, 2022 and 2021, management recognized

$197,000 impairment of Clyra's prepaid marketing asset (see Note 9).





Research and Development


In the year ended December 31, 2022, we spent $1,319,000 in the research and development of our technologies and products. This was a decrease of 4% ($48,000) compared to 2021, due to decreased activity and limited liquidity.





Other Income and Expense


Primarily through our wholly owned Canadian subsidiary, we have been awarded more than 80 research grants over the years from various 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. The amount of grant income increased $19,000 in the year ended December 31, 2022, to $74,000. Grant funds paid directly to third parties are not included as income in our financial statements.

Our Canadian subsidiary applied for and received a refund on our income taxes pursuant to the "Scientific Research and Experimental Development Program", a Canadian federal tax incentive program designed to encourage Canadian businesses to conduct research and development in Canada. For the years ended December 31, 2022 and 2021, we recorded a refund of $63,000 and $20,000, respectively.

The U.S. Small Business Administration forgave a portion ($174,000) of the Paycheck Protection Program loan granted to our subsidiary ONM Environmental during the year ended December 31, 2022; in the prior year, a $43,000 Paycheck Protection Program loan granted to our subsidiary Clyra Medical was forgiven. The Company currently has $97,000 outstanding in Paycheck Protection Program loans that were denied forgiveness, and has appealed those decisions.





Interest expense


Our interest expense for the year ended December 31, 2022, was $53,000, a decrease of 77% compared with 2021. The significant decrease in interest expense is related to the significant decrease of our debt obligations and a reduction of debt issued during 2022 versus 2021. Of our interest expense, $36,000 was paid in cash. Our non-cash interest expenses were $17,000 in amortization of debt discounts related to warrants issued in conjunction with debt instruments.

Our outstanding debt as of December 31, 2022, was lower than as of December 31, 2021. We expect our interest expense in the year ending December 31, 2023, to be in line with the prior year, provided we do not issue debt with attached warrants during the remainder of the year. We also are currently selling units of common stock and warrants instead of using convertible debt for financing our working capital needs, which if continued, will continue to reduce our ongoing interest expense as compared with prior years.

Net Loss


Net loss for the year ended December 31, 2022, was $5,132,000 a loss of $0.02 per share, compared to a net loss for the year ended December 31, 2021, of $6,894,000 a loss of $0.03 per share, a decrease in net loss of 26%. Our net loss this year declined because of the 132% increase in revenues, and 159% increase in gross profit.

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





Net income (loss)        Year ended December       Year ended December
                              31, 2022                  31, 2021
ONM Environmental       $               1,304     $                (511 )
BLEST                                    (425 )                    (629 )
Clyra Medical                          (1,412 )                     593
BioLargo Water                           (604 )                    (566 )
BioLargo corporate                     (3,995 )                  (5,781 )
Consolidated net loss   $              (5,132 )   $              (6,894 )



In the year ended December 31, 2022, approximately 50% of our net loss was attributable to non-cash expenses, including $2,071,000 of stock option compensation expense, and $291,000 of services paid by the issuance of our common stock.

In the year ended December 31, 2021, approximately 40% of our net loss was attributable to non-cash expenses, including $135,000 in interest expense, $1,872,000 of stock option compensation expense, and $367,000 of services paid by the issuance of our common stock. Clyra Medical's net income of $593,000 during the year ended December 31, 2021, was not due to operating activities, but rather due to the recent transaction with Scion Solutions (see Note 9).

The change in Clyra Medical's net income/loss in the years ended December 31, 2022 and 2021 of $2,005,000 is due to the one-time recognition of gain resulting from the March 1, 2022 Scion transaction (see Note 9). Without the one-time recognition of gain, Clyra Medical's net loss for the year ended December 31, 2021, was $1,412,000.

Liquidity and Capital Resources

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of our business. For the year ended December 31, 2022, we had a net loss of $5,132,000, used $2,762,000 cash in operations, and at December 31, 2022, we had working capital of $1,587,000, and current assets of $3,153,000. We do not believe gross profits in 2023 will be sufficient to fund our current level of operations or pay our debts as they become due during the next 12 months, and therefore we will have to obtain further investment capital to continue to fund operations and seek to refinance our existing debt. We have been, and anticipate that we will continue to be, limited in terms of our capital resources.

During the year ended December 31, 2022, we generated revenues of $5,884,000 through our subsidiaries. (See Note 12.) Other than ONM Environmental, our subsidiaries did not individually or in the aggregate generate enough revenues or gross profits to fund their operations, or fund our corporate operations or other business segments. To meet our cash obligations during the year ended December 31, 2022, we (i) sold 6,011,701 shares of our common stock to Lincoln Park for $1,253,000 (see Part II, Item 9B), and (ii) sold 13,568,524 shares of common stock, and issued warrants to purchase 27,137,048 shares of common stock, to private investors for $2,364,000 (see Notes 3 and 6).





                                       30

--------------------------------------------------------------------------------

Table of Contents

As of December 31, 2022, our cash and cash equivalents totaled $1,851,000, and our total liabilities included: $50,000 in convertible debt that was due in March 2023 (subsequent to year end converted to equity); $261,000 owed by our partially owned subsidiary Clyra Medical Technologies, Inc. ("Clyra") due in Sept 2024 (see Note 9); $140,000 due in U.S. Small Business Administration ("SBA") loans issued pursuant to the Paycheck Protection Program (see Note 4); and $150,000 due on an Economic Injury Disaster program (EIDL) payable to the SBA over 30 years at $800 per month.

Subsequent to December 31, 2022, we continue to sell common stock to Lincoln Park for working capital (see Note 14).

If we are unable to rely on our current arrangement with Lincoln Park to fund our working capital requirements, 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. To reduce our operational cash burdens, we regularly issue officers and vendors stock or options 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.

We operate our business in five distinct business segments. Each of these segments obtains cash to fund operations in unique ways. ONM and BLEST generate cash by selling products and services. Clyra Medical obtains cash from revenues, and third-party investments of sales of its common stock. BioLargo Water generates cash through government research grants and tax credits. BioLargo Energy Technologies, Inc. has been capitalized primarily through investments from third parties. Our corporate operations generate cash through private offerings of stock, debt instruments, and warrants.

Although ONM Environmental, BLEST, and Clyra Medical generated revenues in the year ended December 31, 2022, only ONM generated operating and net income. We provided cash subsidies to each of these business segments to allow them to continue operations.





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.





                                       31

--------------------------------------------------------------------------------

Table of Contents

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.

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 two subsidiaries, ONM and BLEST. ONM identifies 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. ONM recognizes revenue at a point in time when the order for its goods are shipped if its agreement with the customer is FOB ONM's warehouse facility, 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 in arrears 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.





Warrants


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.





                                       32

--------------------------------------------------------------------------------

Table of Contents

The warrant 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.





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, 2022 and 2021, approximate their respective fair values because of the short-term nature of these instruments. Such instruments include cash, accounts receivable, prepaid assets, accounts payable, line of credit, and other assets and liabilities. The carrying amount of debt instruments are believed to approximate fair value as the stated interest rates are reflective of the prevailing market rates.
