NOTE 1 - ORGANIZATION AND DESCRIPTION OF BUSINESS

TFF Pharmaceuticals, Inc. (the “Company”) was incorporated in the State of Delaware on January 24, 2018. The Company’s initial focus is on the development of inhaled dry powder drugs to enhance the treatment of pulmonary diseases and conditions. In December 2019, the Company established a wholly-ownedwholly owned Australian subsidiary, TFF Pharmaceuticals Australia Pty Ltd (“TFF Australia”), in order to conduct clinical research. TFF Pharmaceuticals, Inc., along with TFF Australia, are collectively referred to as the “Company”. The Company is in the development stage and is devoting substantially all of its efforts toward technology research and development and the human clinical trials of its initial product candidates.

COVID-19

As of the date of this report, the COVID-19 pandemic has had a relatively insignificant impact on the Company’s operations and has not caused the Company to forego, abandon or materially delay any proposed activities. While the Company believes it has been able to effectively manage the disruption caused by the COVID-19 pandemic to date, there can be no assurance that its operations, including the development of its drug candidates, will not be disrupted or materially adversely affected in the future by the COVID-19 pandemic or an epidemic or outbreak of an infectious disease like the outbreak of COVID-19.

NOTE 2 -– LIQUIDITY AND MANAGEMENT’S PLANS

As of JuneFor the three and nine months ended September 30, 2022, the Company reported a net loss of $7.3 million and $24.4 million, respectively, and negative cash flow from operations for the nine months ended September 30, 2022 of $19.6 million. The Company had an accumulated deficit of $89.7 million and cash and cash equivalents of approximately $20,890,000 and a working capital$13.1 million as of approximately $21,354,000.September 30, 2022. The Company has not generated revenues from commercial operations since inception and has incurred recurring operating losses. The Company expects to continue incurring losses for the foreseeable future and may needneeds to raise additional capital to continue the pursuit of its product development.

For The Three and Nine Months Ended September 30, 2022 and 2021

NOTE 2 – LIQUIDITY AND MANAGEMENT’S PLANS (continued)

The Company expects to further increase its research and development activities, which will increase the amount of cash utilized subsequent to JuneSeptember 30, 2022. Specifically, the Company expects increased spending on research and development activities and higher payroll expenses as it increases itshires additional professional and scientific staff and continues to prepare for anticipated manufacturing activities. If the Company encounters unforeseen delays or expenses, it has the ability to curtail its presently planned level of operations. The Company currentlyplans to seek additional funding through various financing sources, including the sale of its equity and/or debt securities, and/or licensing fees for its technology and co-development and joint ventures with industry partners. The Company believes that its existingcurrent cash and cash equivalents, along withand its access to capital through the expected proceeds fromsale of its equity securities, including the ATM offering, commenced in June 2022, will beare sufficient to fund its operating expenses and capital expenditure requirementspresent plan of operations for at least the next 12 months from the date of issuancefiling of these condensed consolidated financial statements. In addition, the Company will consider alternatives to its current business plan that may enable it to achieve its product development goals with a smaller amount of capital.

NOTE 3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements and with Form 10-Q and Article 10 of Regulation S-X of the United States Securities and Exchange Commission (“SEC”). Accordingly, they do not contain all information and footnotes required by GAAP for annual financial statements. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements contain all the adjustments necessary (consisting only of normal recurring accruals) to present the financial position of the Company as of JuneSeptember 30, 2022 and the results of operations, changes in stockholders’ equity and cash flows for the periods presented. The results of operations for the three and sixnine months ended JuneSeptember 30, 2022 are not necessarily indicative of the operating results for the full fiscal year or any future period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Reclassification

Certain prior period amounts have been reclassified to conform to the current period classification. Amounts received from the United States Internal Revenue Service (“IRS”) for payroll tax credits have been reclassified from other income to operating expenses in the condensed consolidated statements of operations to net the amounts with the related expense that was incurred with no changes in the previously reported net losses.

NOTE 3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued

Principles of Consolidation

The consolidated financial statements include the accounts of TFF Pharmaceuticals, Inc. and its wholly-ownedwholly owned subsidiary, TFF Australia. All material intercompany accounts and transactions have been eliminated in consolidation.

Foreign Currency

The currency of TFF Australia, the Company’s international subsidiary, is in Australian dollars. Foreign currency denominated assets and liabilities are translated into U.S. dollars using the exchange rates in effect at each balance sheet date. Results of operations and cash flows are translated using the average exchange rates throughout the period. The effect of exchange rate fluctuations on translation of assets and liabilities is included as a separate component of stockholders’ equity in accumulated other comprehensive loss.

Cash and Cash Equivalents

The Company maintains its operating accounts in financial institutions in the U.S. and in Australia. The balances are insured up to specified limits. At times, the Company’s cash balances may be uninsured for deposit accounts that exceed insured limits. The Company has not experienced any losses on such accounts. The Company’s cash is maintained in checking accounts and money market funds with maturities of less than three months when purchased, which are readily convertible to known amounts of cash, and which in the opinion of management are subject to insignificant risk of loss in value. As of JuneSeptember 30, 2022 and December 31, 2021, the Company had cash in Australia of AUD$81,70259,664 (US$56,494)38,376) and AUD$831,984 (US$604,944), respectively.

Leases

At the inception of an arrangement, the Company determines whether an arrangement is or contains a lease based on the facts and circumstances present in the arrangement. An arrangement is or contains a lease if the arrangement conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Leases with a term greater than one year are recognized on the condensed consolidated balance sheets as operating lease right-of-use assets and current and long-term operating lease liabilities, as applicable. The Company has elected not to recognize on the condensed consolidated balance sheets leases with terms of 12 months or less. The Company typically only includes the initial lease term in its assessment of a lease arrangement. Options to extend a lease are not included in the Company’s assessment unless there is reasonable certainty that the Company will renew.

Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected remaining lease term. Certain adjustments to the right-of-use asset may be required for items such as prepaid or accrued rent. The interest rate implicit in the Company’s leases is typically not readily determinable. As a result, the Company utilizes its incremental borrowing rate, which reflects the fixed rate at which the Company could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar economic environment.

Revenue Recognition

The Company has entered into feasibility and material transfer agreements (“Feasibility Agreements”) with third parties that provide the Company with funds in return for certain research and development activities. Revenue from the Feasibility Agreements is recognized in the period during which the related qualifying services are rendered and costs are incurred, provided that the applicable conditions under the Feasibility Agreements have been met.

The Feasibility Agreements are on a best-effort basis and do not require scientific achievement as a performance obligation. All fees received under the Feasibility Agreements are non-refundable. The costs associated with the Feasibility Agreements are expensed as incurred and are reflected as a component of research and development expense in the accompanying condensed consolidated statements of operations.

Funds received from the Feasibility Agreements are recorded as revenue as the Company is the principal participant in the arrangement because the activities under the Feasibility Agreements are part of the Company’s development programs. In those instances where the Company first receives consideration in advance of providing underlying services, the Company classifies such consideration as deferred revenue until (or as) the Company provides the underlying services. In those instances where the Company first provides the underlying services prior to its receipt of consideration, the Company records a grant receivable. During the three months ended JuneSeptember 30, 2022 and 2021, the Company rendered the related services and recognized revenue and research and development expenses of $28,004$87,586 and $1,850,$50,000, respectively. During the sixnine months ended JuneSeptember 30, 2022 and 2021, the Company rendered the related services and recognized revenue and research and development expenses of $95,439$183,025 and $1,850,$76,165, respectively. As of JuneSeptember 30, 2022 and December 31, 2021, the Company had receivables due related to Feasibility Agreements of $78,003$232,296 and $11,996, respectively, which is included in prepaid assets and other current assets in the accompanying condensed consolidated balance sheets, and deferred grant revenue of approximately $268,000$362,710 and $50,000, respectively.

NOTE 3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued

Collaborative Arrangements

The Company considers the nature and contractual terms of arrangements and assesses whether an arrangement involves a joint operating activity pursuant to which the Company is an active participant and is exposed to significant risks and rewards dependent on the commercial success of the activity. If the Company is an active participant and is exposed to significant risks and rewards dependent on the commercial success of the activity, the Company accounts for such arrangement as a collaborative arrangement under Accounting Standards Codification (“ASC”) 808, Collaborative Arrangements. ASC 808 describes arrangements within its scope and considerations surrounding presentation and disclosure, with recognition matters subjected to other authoritative guidance, in certain cases by analogy.

For arrangements determined to be within the scope of ASC 808 where a collaborative partner is not a customer for certain research and development activities, the Company accounts for payments received for the reimbursement of research and development costs as a contra-expense in the period such expenses are incurred. This reflects the joint risk sharing nature of these activities within a collaborative arrangement. The Company classifies payments owed or receivables recorded as other current liabilities or prepaid expenses and other current assets, respectively, in the Company’s consolidated balance sheets. Please refer to Note 5, “Joint Development Agreement” for additional details regarding the Company’s joint development agreement (“JDA”) with Augmenta Bioworks, Inc. (“Augmenta”).

If payments from the collaborative partner to the Company represent consideration from a customer in exchange for distinct goods and services provided, then the Company accounts for those payments within the scope of ASC 606, Revenue from Contracts with Customers. The Company does not currently have any collaborative arrangements that are accounted for under ASC 606.

Research and Development Tax Incentive

The Company is eligible to obtain a cash refund from the Australian Taxation Office for eligible research and development expenditures under the Australian R&D Tax Incentive Program (the “Australian Tax Incentive”). The Company recognizes the Australian Tax Incentive when there is reasonable assurance that the cash refund will be received, the relevant expenditure has been incurred, and the consideration can be reliably measured. During the year ended December 31, 2021, the Company received its first cash refund under the Australian Tax Incentive, which was for expenditures incurred during 2020. Therefore, the Company recorded amounts received, or that it expects to receive, for expenditures incurred during 2020 as other income in the condensed consolidated statements of operations during the period ended JuneSeptember 30, 2021.

As the Company has determined that it has reasonable assurance that it will receive the cash refund for eligible research and development expenditures, beginning with expenditures incurred during the year ended December 31, 2021, the Company records the Australian Tax Incentive as a reduction to research and development expenses as the Australian Tax Incentive is not dependent on the Company generating future taxable income, the Company’s ongoing tax status, or tax position. At each period end, management estimates the refundable tax offset available to the Company based on available information at the time. This percentage of eligible research and development expenses reimbursable under the Australian Tax Incentive is 43.5% for the periods ended JuneSeptember 30, 2022 and 2021. In addition, the Company is also eligible to receive amounts from the United States Internal Revenue Service (“IRS”)IRS related to research and development tax credits for expenditures.

The research and development incentive receivable represents amounts due in connection with the Australian Tax Incentive and from the IRS. The Company has recorded a research and development tax incentive receivable of $994,549$949,168 and $966,646 as of JuneSeptember 30, 2022 and December 31, 2021, respectively, in the condensed consolidated balance sheets. The Company has recorded other income (expense) of $20,606$(13,129) and $77,783,$659,695, in the condensed consolidated statements of operations for the three and sixnine months ended June 30, 2022, respectively, related to refundable IRS and Australian research and development incentive program payments for expenditures incurred during 2020. The Company has recorded other income of $441,546 and $672,824, in the condensed consolidated statements of operations for the three and six months ended JuneSeptember 30, 2021, respectively, related to refundable research and development incentive program payments for expenditures incurred during 2020. The Company recorded an increase to research and development expenses as a result of exchange rate changes and adjustments to the estimated amount to be received of $28,834 during the three months ended June 30, 2022 and a reduction to research and development expenses of $144,667 during the six months ended June 30, 2022$25,544 and $516,407$103,307 during the three and sixnine months ended JuneSeptember 30, 2021.2022, respectively, and $219,520 and $735,927 during the three and nine months ended September 30, 2021, respectively.

Basic and Diluted Earnings per Common Share

Basic net loss per common share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and dilutive share equivalents outstanding for the period, determined using the treasury-stock and if-converted methods. Since the Company has had net losses for all periods presented, all potentially dilutive securities are anti-dilutive.

NOTE 3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued

For the sixnine months ended JuneSeptember 30, 2022 and 2021, the Company had the following potential common stock equivalents outstanding which were not included in the calculation of diluted net loss per common share because inclusion thereof would be anti-dilutive:

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Significant estimates include the fair value of stock-based compensation and warrants and the valuation allowance against deferred tax assets and related disclosures. Actual results could differ from those estimates.

Risks and Uncertainties

In December 2019, COVID-19, a novel strain of coronavirus, was first identified in China. In March 2020, the World Health Organization categorized COVID-19 as a pandemic, and the virus has spread to over 100 countries, including the United States. The impact of this pandemic has been and will likely continue to be extensive in many aspects of society, which has resulted in and will likely continue to result in significant disruptions to the global economy, as well as businesses and capital markets around the world.

Potential impacts to the Company’s business include, but are not limited to, temporary closures of facilities of its vendors, disruptions or restrictions on its employees’ ability to travel, disruptions to or delays in ongoing laboratory experiments, preclinical studies, clinical trials, third-party manufacturing supply and other operations, the supply of comparator products, the potential diversion of healthcare resources and staff away from the conduct of clinical trials to focus on pandemic concerns, interruptions or delays in the operations of the U.S. Food and Drug Administration or other regulatory authorities, and the Company’s ability to raise capital and conduct business development activities.

The Company has experienced COVID-19 related delays in its Phase 2 clinical trials for TFF Voriconazole Inhalation Powder (“TFF Vori”) and TFF Tacrolimus Inhalation Powder (“TFF Tac-Lac”). While the Company believes it will be able to effectively manage the delays, there can be no assurance that its operations, including the development of its drug candidates, will not be disrupted or materially adversely affected in the future by the COVID-19 pandemic or an epidemic or outbreak of an infectious disease like the outbreak of COVID-19.

Recent Accounting Standards

There have been no recent accounting pronouncements, changes in accounting pronouncements or recently adopted accounting guidance during the sixnine months ended JuneSeptember 30, 2022 that are of significance or potential significance to the Company.

NOTE 7 - STOCK-BASED COMPENSATION

In January 2018, the Company’s board of directors approved its 2018 Stock Incentive Plan (“2018 Plan”). The 2018 Plan provides for the grant of non-qualified stock options and incentive stock options to purchase shares of the Company’s common stock, the grant of restricted and unrestricted share awards and grant of restricted stock units. The Company initially reserved 1,630,000 shares of its common stock under the 2018 Plan; however, upon completion of the Company’s IPO the number of shares reserved for issuance under the 2018 Plan increased to 3,284,480, representing 15% of the Company’s outstanding shares of common stock calculated on a fully diluted basis upon the close of the IPO. All of the Company’s employees and any subsidiary employees (including officers and directors who are also employees), as well as all of the Company’s nonemployee directors and other consultants, advisors and other persons who provide services to the Company will be eligible to receive incentive awards under the 2018 Plan.

In September 2021, the Company’s board of directors approved its 2021 Stock Incentive Plan (“2021 Plan”), which was also approved by the stockholders of the Company at the Company’s annual meeting of stockholders held on November 4, 2021. The 2021 Plan provides for the grant of non-qualified stock options and incentive stock options to purchase shares of the Company’s common stock, the grant of restricted and unrestricted share awards and grant of restricted stock units. The Company has 4,200,000 shares of its common stock reserved under the 2021 Plan. All of the Company’s employees and any subsidiary employees (including officers and directors who are also employees), as well as all of the Company’s nonemployee directors and other consultants, advisors and other persons who provide services to the Company will be eligible to receive incentive awards under the 2021 Plan.

The following table summarizes the stock-based compensation expense recorded in the Company’s results of operations during the three and sixnine months ended JuneSeptember 30, 2022 and 2021 for stock options and warrants:

As of JuneSeptember 30, 2022, there was approximately $8,045,000$6,708,000 of total unrecognized compensation expense related to non-vested share-based compensation arrangements that are expected to vest. This cost is expected to be recognized over a weighted-average period of 2.11.9 years.

The Company records compensation expense for awards with graded vesting using the straight-line method. The Company recognizes compensation expense over the requisite service period applicable to each individual award, which generally equals the vesting term. The Company estimates the fair value of each option award using the Black-Scholes-Merton option pricing model. Forfeitures are recognized when realized.

The Company estimated the fair value stock options using the Black-Scholes option pricing model.

NOTE 7 - STOCK BASED COMPENSATION, continued

The risk-free interest rate was obtained from U.S. Treasury rates for the applicable periods. The Company’s expected volatility was based upon the historical volatility for industry peers and used an average of those volatilities. The expected life of the Company’s options was determined using the simplified method as a result of limited historical data regarding the Company’s activity for employee awards and the contractual term for nonemployee awards. The dividend yield considers that the Company has not historically paid dividends, and does not expect to pay dividends in the foreseeable future. The Company uses the closing stock price on the date of grant as the fair value of the common stock

The following table summarizes stock option activity during the sixnine months ended JuneSeptember 30, 2022:

The aggregate intrinsic value of stock options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had strike prices lower than the fair value of the Company’s common stock. The intrinsic value of the options exercised during 2022 was approximately $4,000.$76,000.

Option Modification

Effective March 21, 2022, one of the members of the Company’s board of directors, Dr. Brian Windsor, resigned. As part of his resignation from the board of directors, modifications were made to Dr. Windsor’s vested and non-vested stock option awards including acceleration of certain non-vested option awards and the extension of the post-termination exercise period of certain stock option awards. During the sixnine months ended JuneSeptember 30, 2022, in accordance with ASC Topic 718, Compensation—Stock Compensation, the Company recorded a one-time, non-cash incremental compensation expense net of the required reversal of previously recognized compensation attributed to non-vested shares in the amount of approximately $339,000, which is included in general and administrative expense in the accompanying condensed consolidated statements of operations.

Warrants

On June 7, 2022, the Company issued a five-year warrant to purchase 25,000 shares of common stock at $5.70 per share to a consultant. The fair value of the warrant on the grant date was estimated using the Black-Scholes-Merton option pricing model with a common stock value of $5.74 per share, a contractual life of 5.0 years, a dividend yield of 0%, volatility of 96.87% and an assumed risk-free interest rate of 2.99%. The warrant is immediately exercisable. The fair value of the warrant was determined to be approximately $107,000 and was recorded in general and administrative expenses in the condensed consolidated statements of operations forduring the three and six monthsperiod ended JuneSeptember 30, 2022.

In determining the fair value for warrants, the expected life of the Company’s warrants was determined using the contractual life. The methodology in determining all other inputs to calculate the fair value utilizing the Black-Scholes-Merton option pricing model is the same as the stock option methodology described above for stock options.

General

TFF Pharmaceuticals, Inc. (NASDAQ: TFFP) is a clinical stage biopharmaceutical company focused on developing and commercializing innovative drug products based on our patented Thin Film Freezing, or TFF technology platform. We believe, and early testing confirms, that our TFF platform can significantly improve the solubility of poorly water-soluble drugs, a class of drugs that makes up approximately 33% of the major pharmaceuticals worldwide, thereby improving the pharmacokinetic effect of those drugs. We believe that in the case of some new drugs that cannot be developed due to poor water-solubility, our TFF platform has the potential to increase the pharmacokinetic effect of the drug to a level allowing for its development and commercialization.

As of the date of this report, we have three product candidates under development, TFF Voriconazole Inhalation Powder, or TFF Vori; TFF Tacrolimus Inhalation Powder, or TFF Tac-Lac; and TFF Niclosamide Inhalation Powder, or TFF Niclo. In July 2020, we completed Phase I human clinical trials of our lead product, TFF Vori, and completed a Phase 1b clinical trial of TFF Vori in asthma patients in the first quarter of 2022. DosingA Phase 2 clinical trial of TFF Vori in patients with invasive pulmonary aspergillosis in a Phase 2 clinical trial is expected to beginwas initiated in 2022, and we anticipate interim readouts later in the year. Dosing of areporting individual patient in a Compassionate Use Study commenceddata in the first quarter of 2022 for2023. We have reported the positive efficacy and safety data of two patients who have been dosed with Voriconazole Inhalation Powder in a lung transplant patient with a pulmonary fungal infection.compassionate use study. In September 2021, we completed Phase 1 human clinical trials of our TFF Tac-Lac product in Australia. DosingA Phase 2 clinical trial of TFF Tac-Lac in lung transplant patients in a Phase 2 clinical trial is expected to beginwas initiated in 2022 and we anticipate interim readouts laterreporting individual patient data in the year.first half of 2023. In November 2021, we commenced dosing of TFF Niclosamide in a Phase 1 human clinical trial in Canada and completed dosing the Phase 1 trial in January 2022. We and our partner, Union Therapeutics, have not further progressed TFF Niclosamide pending the parties’ further review of the Phase 1 results, animal data, and anti-viral market opportunities. We have not progressed the development of any other of our drug candidates to human clinical trials, and our efforts have focused on the formulation, early-stage animal testing and formal toxicology studies of our initial drug candidates in preparation for our first clinical trials.

We also focused on the joint development of dry powder formulations of proprietary drugs owned or licensed by other pharmaceutical companies. As of the date of this report, we are engaged in the joint development of an inhaled SARS-CoV2 Monoclonal Antibody ina collaboration agreement with Augmenta BioWorks andUNION therapeutics A/S to develop a dry powder formulation of niclosamide in collaboration agreement with UNION therapeutics A/S.niclosamide. We are also actively engaged in the analysis and testing of dry powder formulations of several drugs and vaccines through topical, ocular and nasal applications pursuant to feasibility studies and material transfer agreements with U.S. and international pharmaceutical companies and certain government agencies.

We intend to initially focus on the development of inhaled dry powder drugs for the treatment of pulmonary diseases and conditions. While the TFF platform was designed to improve solubility of poorly water-soluble drugs generally, the researchers at the University of Texas at Austin, or UT, found that the technology was particularly useful in generating dry powder particles with properties which allow for superior inhalation delivery, especially to the deep lung, which is an area of extreme interest in respiratory medicine. We believe that our TFF platform can significantly increase the number of pulmonary drug products that can be delivered by way of breath-actuated inhalers, which are generally considered to be the most effective and patient-friendly means of delivering medication directly to the lungs. Our dry powder drug products will be designed for use with dry powder inhalers, which are generally considered to be the most effective of all breath-actuated inhalers. We plan to focus on developing inhaled dry powder formulations of existing off-patent drugs intended for lung diseases and conditions, which we believe includes dozens of potential drug candidates, many of which have a potential market ranging from $100 million to over $500 million.

We intend to initially focus on the development of the following product candidates:

We have identified a number of additional drug candidates that show promise upon initial evaluation, including dry powder formulations of:

As of the date of this report, we intend to focus on the development of dry powder formulations of CBD and salt containing vaccines in partnership with pharmaceutical companies.   Our intent is for TFF to be involved only through performance characterization of the formulations and early animal efficacy trials.  Beyond that work, if successful, we will transfer further development and commercialization responsibility to the partner as part of a negotiated licensing transaction.

We are also focused on the joint development of dry powder formulations of proprietary drugs owned or licensed by other pharmaceutical companies. As of the date of this report, we are at various stages of different feasibility studies of new chemical entities owned by international pharmaceutical companies. In addition, we recently commenced preliminary analysis and testing of dry powder formulations of certain drugs and vaccines through topical, ocular and nasal applications in connection with our participation in submissions made to certain government agencies for government contracts. Also, in May 2020, we authorized a third party to conduct feasibility studies and market testing of dry powder formulations of cannabis and cannabis-derived products. These efforts have resulted in refinement of specific formulations that we believe could achieve a positive position in the marketplace.

Our business model is to develop proprietary innovative drug product candidates that offer commercial or functional advantages, or both, to currently available alternatives. In our initial evaluation of the market, we have identified a number of potential drug candidates that show promise upon initial assessment. In most cases, these are off-patent drugs for which we would directly pursue the development of a dry powder formulation, however, we do not expect any dry powder formulation of a CBD drug product to be off-patent and our dry powder formulation of aluminum salt vaccines may not be off-patent. In those cases where our initial dry powder drug candidate will be established drugs that are off-patent, such as TFF Vori and TFF Tac-Lac, we believe that our drug product candidates may qualify for approval by the FDA through the FDA’s 505(b)(2) regulatory pathway and in corresponding regulatory paths in other foreign jurisdictions.

The 505(b)(2) pathway sometimes does not require clinical trials other than a bioequivalence trial. Our dry powder formulation of a CBD drug candidate will likely require a full NDA through the FDA’s 505(b)(1) regulatory pathway, however, a non-pharmaceutical CBD dry formulation, such as a dietary supplement, may not require FDA approval. We expect that our dry powder formulation of aluminum salt vaccines will require a biological license application, or BLA, which is very similar to a full NDA through the FDA’s 505(b)(1) regulatory pathway. In addition, to the extent we claim that any of our off-patent drug product candidates target a new indication or offer improved safety compared to the existing approved products, and it is our present expectation that we will in many cases, it is likely that we will be required to conduct additional clinical trials in order to obtain marketing approval.

On November 1, 2020, the Company entered into a joint development and collaboration agreement (the “Agreement”) with Augmenta Bioworks, Inc. (“Augmenta”) pursuant to which the parties agreed to collaborate on the joint development of novel commercial products incorporating Augmenta’s human-derived monoclonal antibodies (“mAbs”) for potential COVID-19 therapeutics. Both companies collaborated to conduct pre-clinical evaluations and successfully formulated the active pharmaceutical ingredient. Based on the pre-clinical results in the Omicron COVID-19 variant, we have suspended further development at this time.

Based on the February 2019 pre-Investigational New Drug Application, or IND, meeting with the FDA, and a March 2022 post-Phase 1 meeting with the FDA concerning TFF Vori, we believe we will need to conduct one Phase 2 study and may need a second Phase 2 or a Phase 2b/3a study prior to filing for marketing approval for TFF Vori. Concerning TFF Tac-Lac, based on a pre-IND meeting with the FDA, we believe we will need to conduct Phase 1 and Phase 2b/3a studies prior to filing for marketing approval for TFF Tac-Lac. However, there can be no assurance that the FDA will not ask for additional clinical data for either TFF Vori or TFF Tac-Lac.

We also believe that in some cases our dry powder drug products may qualify for the FDA’s orphan drug status, such as designated for TFF Tac-Lac. Upon and subject to receipt of the requisite approvals, we intend to commercialize our drug products through a combination of our internal direct sales and third-party marketing and distribution partnerships. In some cases, such as the development of combination drugs or the development of dry powder formulations of patented drugs, we intend to pursue the licensing of our TFF platform or a joint development arrangement.

We were incorporated under the laws of the state of Delaware on January 24, 2018. Our principal executive offices are located at 1751 River Run, Suite 400, Fort Worth, Texas 76107 and our telephone number is (817) 438-6168. Our website address is www.tffpharma.com. The information contained in, or accessible through, our website is not incorporated by reference into this report, and you should not consider any information contained in, or that can be accessed through, our website as part of this report or in deciding whether to purchase our common stock.

On June 10, 2022, we entered into an Open Market Sale Agreement with Jefferies LLC, as agent, under which we may offer and sell, from time to time at our sole discretion, shares of our common stock having an aggregate offering price of up to $35.0 million in an “at-the-market” or ATM offering, to or through the agent. As of JuneThrough September 30, 2022, no shares had beenthe Company sold in the ATM offering. Between July 1, 2022 and August 5, 2022, we sold 72,096104,011 shares of ourits common stock at average price of $5.92$5.96 per share resulting in net proceeds of approximately $414,273.$405,000, after deducting offering expenses.

Results of Operations

We were formed in January 2018 and have not commenced revenue-producing operations. To date, our operations have consisted of the development and early-stage testing and Phase 1 human clinical trials of our initial product candidates.

In December 2019, we established a wholly-ownedwholly owned Australian subsidiary, TFF Pharmaceuticals Australia Pty Ltd. in order to conduct clinical research.

As of the date of this report, the COVID-19 pandemic has had a relatively insignificant impact on our operations and has not caused us to forego, abandon or materially delay any proposed activities. While we believe we have been able to effectively manage the disruption caused by the COVID-19 pandemic to date, there can be no assurance that our operations, including the development of our drug candidates, will not be disrupted or materially adversely affected in the future by the COVID-19 pandemic or an epidemic or outbreak of an infectious disease like the outbreak of COVID-19.

The following table summarizes our results of operations with respect to the items set forth below for the three months ended JuneSeptember 30, 2022 and 2021 together with the percentage change for those items.

We have entered into feasibility and material transfer agreements with third parties that provide us with funds in return for certain research and development activities. During the three months ended JuneSeptember 30, 2022 and 2021, we recognized $28,004$87,586 and $1,850,$50,000, respectively, of grant revenue.

During the three months ended JuneSeptember 30, 2022 and 2021, we incurred $5.1$4.0 million and $2.8$6.3 million of research and development expenses and $3.7$3.3 million and $2.4 million of general and administrative expenses, respectively.

The change in research and development expenses during 2022 was mainly due to increased clinical expenses of approximately $1.8 million$210,000 related to Niclosamide, TFF Vori and TFF Tac-Lac, increased payroll and related expense of approximately $289,000 and increased stock-based compensation of approximately $175,000,$91,000, and increased lab expenses of approximately $122,000, offset by a decrease in manufacturing costs of approximately $102,000$1.7 million (which includes a decrease of approximately $374,000$342,000 in manufacturing expense related to the Augmenta monoclonal antibody), and a decrease in preclinical expenses of approximately $148,000.$1.0 million and a decrease in payroll and related expense of approximately $84,000. The change in research and development expenses also includes our preliminary analysis and testing of dry powder formulations of several drugs and vaccines owned or licensed by third parties we believe may lead to the out-licensing of our TFF technology for the development of dry powder product candidates. We expect our spending on research and development activities to increase in upcoming quarters due primarily to clinical trial activity.

The increase in general and administrative expenses in 2022 from the prior year was mainly a result of increases in insurance and investor relation expenses of approximately $464,000,$544,000, and consulting and business development expenses of approximately $299,000, stock-based compensation expenses of approximately $280,000 and payroll and related expenses of approximately $95,000.$288,000, along with other general increases. While we expect our general and administrative expenses to continue to increase over the next few years, we anticipate the rate of increase has begun to decrease.

The following table summarizes our other income and interest income for the three months ended JuneSeptember 30, 2022 and 2021 together with the percentage change for those items.
