Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Introduction

The following unaudited pro forma condensed combined financial information is presented to illustrate the estimated effect of the recently completed acquisition (the “DERMAdoctor Acquisition”) by NovaBay Pharmaceuticals, Inc. (“NovaBay”, “we”, “our” and “us”) of DERMAdoctor, LLC (“DERMAdoctor”) pursuant to the terms of the Membership Unit Purchase Agreement, dated September 27, 2021 (the “Acquisition Purchase Agreement”), by and among (i) NovaBay, (ii) DERMAdoctor, (iii) Dr. Jeffrey Kunin and Dr. Audrey Kunin (the “Founders”), (iv) Papillon Partners, Inc., a Missouri corporation that is owned by the Founders (“Papillon”) and (v) Midwest Growth Partners, L.L.L.P., an Iowa limited liability limited partnership (together with Papillon, the “Sellers”), for the purchase price of approximately $15.0 million (the “Purchase Price”). The DERMAdoctor Acquisition closed on November 5, 2021 (the “Acquisition Closing”). The Purchase Price was comprised of a payment to the Sellers of approximately $12.0 million in cash at the Acquisition Closing, which amount was (x) reduced by amounts paid to satisfy DERMAdoctor’s indebtedness and its transaction expenses as of the Acquisition Closing, and (y) increased by the amount of remaining DERMAdoctor cash and cash equivalents as of the Acquisition Closing. In addition, $1.2 million of the Purchase Price paid at the Acquisition Closing was deposited into an escrow account, which amount is available to NovaBay to satisfy indemnification obligations of the Founders and the Sellers in accordance with the Acquisition Purchase Agreement. The remaining amount of the Purchase Price is comprised of up to an aggregate of $3.0 million in earn out payments, which are contingent upon the legacy DERMAdoctor business achieving predetermined financial targets for the 2022 and the 2023 calendar years (the “Earn Out Payments”).

The unaudited pro forma condensed combined financial information also presents the pro forma effects of our private placement of 15,000 shares of our Series B Non-Voting Convertible Preferred Stock, par value $0.01 per share (the “Preferred Stock”), convertible into an aggregate of 37,500,000 shares of NovaBay common stock, par value $0.01 per share (the “Common Stock”), and Common Stock warrants (the “Warrants”) exercisable for an aggregate of 37,500,000 shares of Common Stock, which we completed on November 2, 2021 (the “Private Placement”). We received gross proceeds of $15.0 million in the Private Placement, which proceeds were partially used to fund the Purchase Price at the Acquisition Closing.

The unaudited pro forma condensed combined financial information presented has been prepared in accordance with Article 11 of Regulation S-X, Pro Forma Financial Information, as amended by the SEC’s final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses,” and are being provided pursuant to Rule 3-05 of Regulation S-X as a result of the DERMAdoctor Acquisition having been completed.

Release No. 33-10786 replaces the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction (the “Transaction Accounting Adjustments”) and the option to present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). NovaBay has elected not to present Management’s Adjustments and has only presented Transaction Accounting Adjustments in the following unaudited pro forma condensed combined financial information. 

The unaudited pro forma condensed combined balance sheet as of September 30, 2021 combines the historical balance sheets of NovaBay and DERMAdoctor on a pro forma basis giving effect to the DERMAdoctor Acquisition and Private Placement as if they had been completed on September 30, 2021. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2021 and for the year ended December 31, 2020 combine the historical statements of operations of NovaBay and DERMAdoctor giving effect to the DERMAdoctor Acquisition and Private Placement as if they had been completed on January 1, 2020, the earliest period presented.

The pro forma adjustments and allocation of the Purchase Price are preliminary, are based on management’s current estimates of the fair value of the acquired assets and assumed liabilities, and are based on currently available information, including preliminary work performed by independent valuation specialists. In addition to the DERMAdoctor Acquisition, the unaudited pro forma condensed combined financial information provides for the anticipated effects of and the use of proceeds from the Private Placement.

As of the date of this Amendment No. 1, we have not completed the detailed valuation analysis and calculations necessary to arrive at final estimates of the fair market value of the assets of DERMAdoctor to be acquired and the liabilities to be assumed and the related allocations of the Purchase Price, nor have we identified all adjustments necessary to conform DERMAdoctor’s accounting policies to our accounting policies. Accordingly, certain of DERMAdoctor’s assets and liabilities are presented at their respective carrying amounts and should be treated as preliminary values. 

Actual results will differ from the unaudited pro forma condensed combined financial information provided herein once we have completed the valuation analysis necessary to finalize the required Purchase Price allocations and identified any additional conforming accounting policy changes for DERMAdoctor. There can be no assurance that such finalization will not result in material changes to the unaudited pro forma condensed combined financial information presented.

Additionally, we have not yet completed a detailed analysis of the accounting impact of the Private Placement and therefore, the pro forma presentation of the Private Placement is also preliminary. Actual results will differ from the unaudited pro forma condensed combined financial information provided herein once we have completed a detailed analysis.

There can be no assurance that such finalization of the items above will not result in material changes to the unaudited pro forma condensed combined financial information presented.

Assumptions and estimates underlying the unaudited pro forma adjustments set forth in the unaudited pro forma condensed combined financial statements are described in the accompanying notes below. The unaudited pro forma adjustments represent management’s estimates based on information available as of the date of these unaudited pro forma condensed combined financial statements and are subject to change as additional information becomes available and analyses are performed.

The unaudited pro forma condensed combined financial information and accompanying notes are based on, and should be read in conjunction with, (i) the historical audited consolidated financial statements of NovaBay and accompanying notes for the year ended December 31, 2020, which are included in our Annual Report on Form 10-K filed with the SEC on March 25, 2021 and the historical unaudited consolidated financial statements of NovaBay and accompanying notes for the period ended September 30, 2021, which are included in our Quarterly Report on Form 10-Q filed with the SEC on November 12, 2021, (ii) the historical audited financial statements of DERMAdoctor and accompanying notes included for the year ended December 31, 2020 and the historical unaudited financial statements of DERMAdoctor and accompanying notes for the nine-month period ended September 30, 2021, each of which are included in this Amendment No. 1.

The following unaudited pro forma condensed combined financial statements are provided for illustrative purposes only and are based on currently available information and assumptions that we believe are reasonable under the circumstances. They do not purport to represent what our actual consolidated results of operations or the consolidated financial position would have been had the DERMAdoctor Acquisition and Private Placement been completed on the dates indicated, or on any other date, nor are they necessarily indicative of our future consolidated results of operations or consolidated financial position after the DERMAdoctor Acquisition is completed. Accordingly, our actual financial position and results of operations will differ, perhaps significantly, from the pro forma amounts reflected herein due to a variety of factors, including changes in value not currently identified and changes in operating results of NovaBay and DERMAdoctor following the date of the unaudited pro forma condensed combined financial statements.

Note 1. Basis of Pro Forma Presentation

The unaudited pro forma condensed combined financial statements are derived from the historical consolidated financial statements of NovaBay and the historical financial statements of DERMAdoctor. The unaudited pro forma condensed combined financial statements are prepared as a business combination using the purchase accounting method.

The unaudited pro forma condensed combined balance sheet has been prepared to reflect the transaction as if the DERMAdoctor Acquisition had been completed on September 30, 2021. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2021 and for the year ended December 31, 2020 combine the historical statements of operations of NovaBay and DERMAdoctor giving effect to the DERMAdoctor Acquisition as if it had been completed on January 1, 2020, the earliest period presented.

The DERMAdoctor Acquisition will be accounted for under the purchase accounting method of accounting in accordance with FASB ASC 805, Business Combinations, using the fair value concepts defined in ASC 820, Fair Value Measurements and Disclosures. We are treated as the “acquirer” and DERMAdoctor is treated as the “acquired” company for financial reporting purposes. Accordingly, the purchase consideration allocated to the DERMAdoctor business’s assets and liabilities for preparation of the unaudited pro forma condensed combined sheet is based upon its estimated preliminary fair values assuming the DERMAdoctor Acquisition was completed as of September 30, 2021. The amount of the purchase consideration that was in excess of the estimated preliminary fair values of the DERMAdoctor business’s net assets and liabilities at September 30, 2021 is recorded as goodwill in the unaudited pro forma condensed combined balance sheet. 

We have not yet performed the detailed valuation studies necessary to arrive at the final estimates of the fair value of DERMAdoctor’s acquired assets, the assumed liabilities and the related allocations of the Purchase Price.

The unaudited pro forma condensed financial information includes pro forma adjustments that are (i) directly attributable to the DERMAdoctor Acquisition, (ii) factually supportable, and (iii) with respect to the unaudited condensed pro forma statements of operations, expected to have a continuing impact on the results of operations of the combined company.

Actual results may differ from these unaudited pro forma condensed combined financial statements once we have determined the final Purchase Price for DERMAdoctor and have completed the valuation studies necessary to finalize the required Purchase Price allocations and identified any additional conforming accounting policy changes for DERMAdoctor. There can be no assurance that such finalization will not result in material changes to the unaudited pro forma condensed combined financial information presented. The preliminary unaudited pro forma Purchase Price allocation has been made solely for preparing these unaudited pro forma condensed combined financial statements.

Additionally, we have not yet completed a detailed analysis of the accounting impact of the Private Placement and therefore, the pro forma presentation of the Private Placement is also preliminary. Actual results will differ from the unaudited pro forma condensed combined financial information provided herein once we have completed a detailed analysis. These unaudited pro forma condensed combined financial statements are presented for illustrative purposes only and do not give effect to any cost savings from operating efficiencies, revenue synergies, differences in stand-alone costs of the DERMAdoctor business or costs for the integration of DERMAdoctor’s business operations with NovaBay. These unaudited pro forma condensed combined financial statements do not purport to represent what the actual consolidated results of operations of NovaBay would have been had the DERMAdoctor Acquisition been completed on the dates assumed, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position. Any transaction, separation or integration costs will be expensed in the appropriate accounting periods after completion of the DERMAdoctor Acquisition. 

Note 2. Accounting Policies 

The unaudited pro forma condensed combined financial statements may not reflect all reclassifications necessary to conform DERMAdoctor’s presentation to that of NovaBay’s due to limitations on the availability of information as of the date of this Amendment No. 1. As a result of the completion of the DERMAdoctor Acquisition, we will further review DERMAdoctor’s accounting policies. As a result of that review, we may identify differences between the accounting policies of the two companies that, when conformed, could have a material impact on the combined financial statements. 

Note 3. Preliminary Purchase Consideration and Purchase Price Allocation 

Under the purchase method of accounting, the identifiable assets acquired and liabilities assumed are recorded at the fair values. The Purchase Price allocation provided in these unaudited pro forma condensed combined financial statements is preliminary and based on estimates of the fair value as of September 30, 2021 and not the actual date of the Acquisition Closing.

We have engaged a third-party valuation company to assist us with the valuation of DERMAdoctor and its assets and liabilities. The detailed valuation necessary to estimate the fair value of the assets acquired and liabilities assumed has not yet been completed; accordingly, the adjustments to record the assets acquired and liabilities assumed at fair value reflect the best estimate of NovaBay based on the information currently available and are subject to change once additional analyses are completed.

There can be no assurance that such third-party valuation work will not result in material changes from the preliminary accounting treatment included in the accompanying unaudited pro forma condensed combined financial statements.

The Purchase Price as provided in the Acquisition Purchase Agreement provides for the Sellers to receive up to $15.0 million in connection with the DERMAdoctor Acquisition, of which $12.0 million in cash was paid at the Acquisition Closing and up to $3.0 million in Earn Out Payments may become payable to the Sellers in the future if the legacy DERMAdoctor business achieves predetermined financial targets for the 2022 and the 2023 calendar years. In addition, $1.2 million of the Purchase Price at the Acquisition Closing was deposited into an escrow account, which amount is available to NovaBay to satisfy indemnification obligations of the Founders and the Sellers in accordance with the Acquisition Purchase Agreement. As a result of the contingent nature of the Earn Out Payments and for purposes of the unaudited pro forma condensed combined financial statements, we have estimated the total amount for the DERMAdoctor Acquisition to be $12.75 million, comprised of a cash payment of $12.0 million and $750,000 for the preliminary estimated fair value of the Earn Out Payments.

The estimated fair value of the Earn Out Payments is preliminary and based upon available information and certain assumptions, known at the time of this report, which management believes are reasonable. This preliminary fair value estimate for the Earn Out Payments may change as additional information becomes available and such changes could be material. Upon final determination of the fair value of the Earn Out Payments, any differences in the actual Earn Out Payments will be recorded in operating income (expense) in the consolidated statements of operations.

The table below represents a preliminary allocation of the estimated total Purchase Price to the DERMAdoctor business’s assets and liabilities in the DERMAdoctor Acquisition based on our preliminary estimate of their respective fair values: 

Goodwill represents the amount of the Purchase Price in excess of the estimated preliminary amounts assigned to the fair value of the DERMAdoctor assets acquired and the liabilities assumed. Since these amounts are estimates, the final amount of goodwill recorded may differ materially from the amount presented.

Our unaudited preliminary allocation of the estimated total Purchase Price includes certain identifiable intangible assets with an estimated fair value of approximately $3.3 million. Customer relationships and trade secrets / product formulation are expected to have a finite life and are expected to be amortized using the straight-line method over the respective lives of each asset, while trade name is not expected to be amortized. Trade name will be tested for impairment at least annually for events or circumstances that may indicate a possible impairment exists.

Goodwill is expected to be recorded for the excess of the consideration transferred over the preliminary fair value of the assets acquired and liabilities assumed. Goodwill will not be amortized, but instead will be tested for impairment at least annually for events or circumstances that may indicate a possible impairment exists. In the event management determines that the value of goodwill has been impaired, we will incur an impairment charge during the period in which the determination is made.

The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2021 and for the year ended December 31, 2020 include pro forma adjustments related to the amortization of the intangible assets acquired. For pro forma purposes, the finite life intangible assets are amortized on a straight-line basis beginning on January 1, 2020, as if the DERMAdoctor Acquisition occurred on that date.

The preliminary fair value of the identifiable intangible assets acquired was estimated using a combination of asset-based and income-based valuation methodologies. The asset-based valuation methodology established a fair value estimate based on the cost of replacing the asset, less amortization from functional use and economic obsolescence, if present and measurable. The income-based valuation methodology utilizes a discounted cash flow technique where the expected future economic benefits of ownership of an asset are discounted back to present value. This valuation technique requires us to make certain assumptions about future operating performance and cash flow, and other such variables which are discounted to present value using a discount rate that reflects the risk factors associated with future cash flow, the characteristics of the assets acquired, and the experience of the acquired business. Such valuation methodologies and estimates are subject to change, possibly materially, as additional information becomes available and as additional analyses are performed.

The unaudited preliminary allocation of the estimated Purchase Price has been made solely for the purpose of preparing these unaudited pro forma condensed combined financial statements.

The final total consideration and amounts allocated to DERMAdoctor’s acquired assets and assumed liabilities could differ materially from the preliminary amounts presented in these unaudited pro forma condensed combined financial statements. A decrease in the fair value of the assets or an increase in the fair value of the liabilities from the preliminary valuations presented would result in a dollar-for-dollar corresponding increase in the amount of goodwill that will result from the DERMAdoctor Acquisition. In addition, if the value of the property and equipment and identifiable intangible assets is higher than the amounts included in these unaudited pro forma condensed combined financial statements, it may result in higher depreciation and amortization expense than is presented in the unaudited pro forma condensed combined statements of operations. Any such increases could be material and could result in our actual future financial condition and results of operations differing materially from those presented in the unaudited pro forma condensed combined financial statements. 

Note 4. Adjustments to Unaudited Pro Forma Condensed Combined Financial Statements 

The unaudited pro forma condensed combined financial information has been prepared to illustrate the effect of the DERMAdoctor Acquisition and has been prepared for informational purposes only. They do not purport to indicate the results of future operations or the financial position of either company.

The historical financial statements have been adjusted in the unaudited pro forma condensed combined financial information to give pro forma effect to events that are directly attributable to the DERMAdoctor Acquisition, factually supportable, and with respect to the statements of operations, expected to have a continuing impact on the results of NovaBay.

The following items are presented as reclassifications in the unaudited pro forma condensed combined financial statements for purposes of conforming DERMAdoctor’s classification of certain assets, liabilities, income, and expenses to our presentation for the combined presentation:
