Notes to Unaudited Condensed Consolidated Financial Statements For the Three and Six Months Ended June 30, 2025 |
Unless the context otherwise requires, references to the “Company,” the “combined company,” “Mosaic,” “we,” “our,” or “us” in this Quarterly Report on Form 10-Q ("Report" or “Quarterly Report”) refer to Mosaic ImmunoEngineering, Inc. and its subsidiaries.
| 1. | Organization and Business |
Organization
Mosaic ImmunoEngineering, Inc. (the “Company,” “Mosaic,” “we,” “us,” or “our”) is a corporation organized under Delaware law on March 24, 1992. We are a development-stage biotechnology company focused on advancing and eventually commercializing immunotherapies for the treatment of cancer. We have historically advanced early-stage product candidate and we are pursuing new product candidates and platforms to expand our pipeline based on our understanding of immunotherapies and our license agreements with University of California San Diego.
The Company has two inactive wholly owned subsidiaries: Mosaic ImmunoEngineering Development Company, a corporation organized under Delaware law on March 30, 2020 and Patriot Data Solutions Group, Inc.
Going Concern and Management’s Plans
The accompanying unaudited condensed consolidated
financial statements have been prepared assuming the Company will continue as a going concern. At June 30, 2025, the Company had cash
and cash equivalents of $
There are a number of uncertainties associated with our ability to raise additional capital and we have no current arrangements with respect to any additional financing. In addition, the continuation of disruptions caused by COVID-19 or other variants or pandemics, broad-based inflation, and various economic indicators that the United States economy may be entering a recession in upcoming quarters may cause investors to slow down or delay their decision to deploy capital which will adversely impact our ability to fund future operations. Consequently, there can be no assurance that any additional financing on commercially reasonable terms, or at all, will be available when needed. The inability to obtain additional capital will delay our ability to conduct our business operations. Any additional equity financing may involve substantial dilution to our then existing stockholders. The above matters raise substantial doubt regarding our ability to continue as a going concern.
| 2. | Basis of Presentation and Significant Accounting Policies |
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America. The accompanying unaudited condensed consolidated financial statements should therefore be read in conjunction with the consolidated financial statements and notes thereto for the fiscal year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern. In the opinion of management, the interim condensed consolidated financial statements reflect all adjustments of a normal recurring nature necessary for a fair presentation of the results for the interim period presented.

Significant Accounting Policies
There have been no material changes to the Company’s significant accounting policies during the three and six months ended June 30, 2025, as compared to the significant accounting policies disclosed in Note 2 – Summary of Significant Accounting Policies included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.
Recently Adopted Accounting Standards
There have been no additional accounting pronouncements adopted by the Company or new accounting pronouncements issued by the Financial Accounting Standards Board (“FASB”) during the three and six months ended June 30, 2025, as compared to the recent accounting pronouncements described in Note 2 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, that the Company believes are of significance or potential significance to the Company.
| 3. | Fair Value of Financial Instruments |
Under this authoritative guidance, we are required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We determine fair value based on quoted prices when available or through the use of alternative approaches, such as discounting the expected cash flows using market interest rates commensurate with the credit quality and duration of the investment or valuations by third-party professionals. The three levels of inputs that we may use to measure fair value are:
| · | Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; | |
| · | Level 2: Quoted prices in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and | |
| · | Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). |
The carrying amount of certain of the Company’s financial instruments, including cash and cash equivalents, accounts payable and accrued liabilities, approximate their estimated fair values primarily due to the short-term nature of the instruments or based on information obtained from market sources and management estimates. Convertible notes were initially recorded at their amortized cost and were accreted to their redemption value over the estimated conversion period using the effective interest method (Note 6).
| 4. | Accrued Expenses and Other Current Liabilities |
Accrued expenses and other current liabilities consisted of the following:

| 5. | License Agreements |
License Option Agreement and License Agreement with CWRU
On July 1, 2020, we signed a License Option Agreement
with CWRU, granting the Company the exclusive right to license certain technology covering an immunotherapy platform technology to treat
and prevent cancer in humans and for veterinary use. On May 4, 2022, we exercised our rights under the License Option Agreement and entered
into a license agreement with CWRU (“License Agreement”). On March 22, 2024, we received a notice of termination from CWRU
to terminate the License Agreement effective on the notice date. As of June 30, 2025 and December 31, 2024, we have accrued $
License Agreements with University of California San Diego (“UC San Diego”)
During July 2021, we licensed the exclusive rights
from UC San Diego to develop and commercialize technology that involves the loading of immuno-stimulatory molecules into plant virus protein
nanoparticles. These plant virus protein nanoparticles can be loaded with other TLR agonists to further tailor specific immune response
parameters. Under the licensing agreement, we are obligated to pay (i) a nominal upfront license access fee, (ii) all patent costs incurred
prior to the effective date of the license agreement, (iii) annual license maintenance fees beginning on the second anniversary date of
the agreement, (iv) aggregate future milestone payments based on potential clinical development and regulatory milestones of up to $

| 6. | Convertible Notes |
On May 7, 2021, we entered into a convertible note
purchase agreement (“May Note Agreement”) with five (5) accredited investors, including three (3) members of our Board of
Directors (“Board”) that participated on the same terms as other accredited investors. Pursuant to the Note Agreement, we
received $
| 10 |
On February 18, 2022, we entered into additional convertible
note purchase agreements (“February Note Agreement”) with sixteen (16) accredited investors, including five (5) members of
our Board that participated on the same terms as other accredited investors. Pursuant to the February Note Agreement, we received $
The May and February Convertible Notes (collectively,
the “Convertible Notes”) have no stated maturity date; bear interest at a simple rate equal to eight percent (
The Convertible Notes will convert into the same equity securities offered in the Qualified Financing or Smaller Financing (“Conversion Shares”), as described below, at a conversion price equal to the lower of (i) the product equal to 80% times the lowest per unit purchase price of the equity securities issued for cash in the Qualified Financing or Smaller Financing, or (ii) $2.377 for the May Convertible Notes (“May Conversion Price”) or $1.00 for the February Convertible Notes (“February Conversion Price”). Pursuant to the February Note Agreement, for each holder of the May Convertible Notes that purchased a February Convertible Note in the amount of (a) $50,000 or (b) an amount equivalent to the principal amount of their May Convertible Note, the conversion price of the May Convertible Notes was adjusted to the February Conversion Price. As of June 30, 2025, the principal amount of the Convertible Notes that may be converted at the February Conversion Price was $866,632. In addition, the conversion price may be reduced or increased proportionately as a result of stock splits, stock dividends, recapitalizations, reorganizations, and similar transactions. Upon any conversion of the Convertible Notes in connection with a Qualified Financing or a Smaller Financing, as applicable, the Convertible Notes shall convert immediately prior to the closing thereof, such that the investors paying cash in such Qualified Financing or Smaller Financing, as applicable, are not diluted by the conversion of the Convertible Notes.
Pursuant to the Convertible Notes, a Qualified Financing represents a single transaction or series of transactions whereby the Company receives aggregate gross proceeds of at least $5 million from the sale of equity securities following the issuance date (excluding proceeds from the issuance of any future convertible notes). A Smaller Financing represents any sale of equity securities whereby the aggregate gross proceeds are less than $5 million (excluding proceeds from the issuance of any future convertible notes).
In addition, in the event of a corporate transaction covering the sale of all or substantially all of the Company’s assets, or merger or consolidation with or into another entity, or change in ownership of at least 50% in voting securities of the Company, the holder of the Convertible Note may elect that either: (a) the Company pay the holder of such Convertible Note an amount equal to the sum of (i) all accrued and unpaid interest due on such Convertible Note and (ii) one and one-half (1.5) times the outstanding principal balance of such Convertible Note; or (b) such Convertible Note will convert into that number of conversion shares equal to the quotient obtained by dividing (i) the outstanding principal balance and unpaid accrued interest of such Convertible Note on the date of conversion by (ii) the May or February Conversion Price, as applicable.
Pursuant to ASC Topic 835-30, “Imputation of
Interest”, the Convertible Notes were initially recorded at their amortized cost of $916,632 and are being accreted to their redemption
value of $

| 7. | Note Payable |
On November 18, 2024, we entered into an unsecured
convertible promissory note (“Note Purchase Agreement”) with an accredited investor (“Investor”) for proceeds
of up to $
| 8. | Stockholders’ Equity and Share-Based Compensation |
Stockholders’ Equity (Deficit)
The Company’s authorized capital consists of shares of common stock, par value $ per share, and shares of preferred stock, par value $ per share (“Preferred Stock”). We designated shares of Series A Convertible Voting Preferred Stock (“Series A Preferred”) and designated and issued shares of Series B Convertible Voting Preferred Stock (“Series B Preferred”). As of June 30, 2025 and December 31, 2024, there are shares of Series A Preferred outstanding and shares of Series B Preferred outstanding.
Series B Preferred
On August 21, 2020, the Company issued 70,000 shares of Series B Preferred (classified as permanent equity), in exchange for 70,000 shares of Class B Common Stock in connection with the reverse merger in August 2020. Each share of Series B Preferred has a par value of $0.00001 per share, no dividend rate, a stated value of $6.50 per share, and each share of Series B Preferred initially converts into 11.46837 shares of common stock of the Company (“Series B Conversion Number”). In addition, the Series B Preferred possesses full voting rights, on an as-converted basis, as the common stock of the Company, as defined in the Series B Certificate of Designation. Furthermore, the Series B Preferred does not have any mandatory conversion rights and only converts upon written notice from the holder.
The Series B Preferred also includes certain anti-dilution rights (“anti-dilution issuance rights”), whereby the holder of Series B Preferred will continue to maintain ownership equal to 10% of the fully diluted shares of common stock outstanding, including for such purposes all other convertible securities outstanding and reserved for issuance except equity awards issued and outstanding and reserved for issuance under a board approved equity compensation plan reserving for issuance no more than ten percent (10%) of the outstanding common stock of the Company then outstanding, until the Capital Threshold is met. The anti-dilution issuance rights meet the definition of a derivative instrument under FASB’s ASC Topic 815. As of December 31, 2023, the $1 million dollar Capital Threshold was achieved and therefore, there is no remaining derivative liability.
In the event of any Liquidation Event, the Holders of Series B Preferred shall be entitled to receive, prior and in preference to any distribution of any of the assets or surplus funds of the Company to the holders of common stock, an amount per share in cash equal to the greater of (x) the stated value of $6.50 for each share of Series B Preferred then held by the holder or (y) the amount payable per share of common stock which such holder of Series B Preferred would have received if such Holder had converted to common stock immediately prior to the Liquidation Event.

Share-Based Compensation
2020 Omnibus Incentive Plan
On October 21, 2020, we adopted our 2020 Omnibus Incentive
Plan (the “2020 Plan”) and on October 22, 2020, the 2020 Plan was approved by our stockholders. The 2020 Plan was adopted
to promote our long-term success and the creation of stockholder value by motivating participants, through equity incentive awards, to
achieve long-term success in our business. The 2020 Plan permits the discretionary award of stock options, restricted stock, RSUs, and
other equity awards to selected participants. On October 21, 2021, the first anniversary date from the adoption date of the 2020 Plan,
the number of shares of common stock reserved for issuance under the 2020 Plan increased to 20% of the fully diluted shares of common
stock outstanding, including shares of common stock reserved for issuance under convertible securities. As of June 30, 2025, we have reserved
The cost of all share-based awards will be recognized in the consolidated financial statements based on the fair value of the awards. The fair value of stock option awards will be determined using the Black-Scholes valuation model on the date of grant. The fair value of restricted stock awards and RSUs will be equal to the closing market price of our common stock on the date of grant. The Company will generally recognize share-based compensation expense over the period of vesting or period that services will be provided for all time-based awards. There was no share-based compensation expense for the three months ended June 30, 2025 and 2024. Share-based compensation expense for the six months ended June 30, 2025 and 2024 was comprised of the following:

Legal Matters
While the Company is not involved in any litigation as of June 30, 2025, the Company may be involved in various lawsuits and claims arising in the ordinary course of business, including actions with respect to intellectual property, employment, and contractual matters. Any litigation could have a material adverse effect on the Company’s business, financial condition, results of operations, and/or cash flows in the period in which the unfavorable outcome occurs or becomes probable, and potentially in future periods.
Indemnification
We have made certain guarantees and indemnities, under which we may be required to make payments to a guaranteed or indemnified party. We indemnify our directors, officers, employees, and agents to the maximum extent permitted under the laws of the State of Delaware. The duration of the guarantees and indemnities varies, and in many cases is indefinite. These guarantees and indemnities do not provide for any limitation of the maximum potential future payments we could be obligated to make. Historically, we have not been obligated to make any payments for these obligations and no liabilities have been recorded for these guarantees and indemnities in the accompanying unaudited condensed consolidated balance sheets.
Escrow Shares
On August 31, 2009, we gave notice to the former shareholders of Crossflo and Union Bank of California (the “Escrow Agent”) under Section 2.5 of the Agreement and Plan of Merger between us and Crossflo (the “Agreement”), outlining damages incurred by us in conjunction with the acquisition of Crossflo, and seeking the return of 5,690 shares of our common stock held by the Escrow Agent. Subsequently, former shareholders of Crossflo, representing a majority of the escrowed shares responded in protest to our claim, delaying the release of the escrowed shares until a formal resolution is reached. In the event we fail to prevail in our claim against the escrowed shares, we may be obligated to deposit into escrow approximately $256,000 of cash consideration due to the decline in our average stock price over the one-year escrow period calculated in accordance with the agreement. We have evaluated the potential for loss regarding our claim and believe that it is probable that the resolution of this issue will not result in a material obligation to the Company, although there is no assurance of this. Accordingly, we have not recorded any liability for this matter.

During April 2021, we entered into consulting agreements (retroactive to September 1, 2020) with Nicole Steinmetz, Ph.D., former acting Chief Scientific Officer and former member of the Board of Directors, Jonathan Pokorski, Ph.D. (Dr. Steinmetz’s spouse), and Steve Fiering, Ph.D., each a co-founder of the company acquired in the reverse merger and greater than 5% shareholder of the Company (“Related Parties”), for their scientific contributions towards advancing the technology platforms. On May 2, 2023, Dr. Steinmetz resigned from the Board of Directors and her role as acting Chief Scientific Officer under her consulting agreement.

During the three six months ended June 30, 2025 and
2024, we did not incur any related party consulting expenses. Pursuant to the consulting agreements, Dr. Steinmetz, Dr. Pokorski, and
Dr. Fiering are initially paid 15% of their monthly amounts up and until the Company is able to raise at least $4 million in new funding.
In exchange for the deferral of consulting payments, the Company agreed to grant each of the Related Parties RSU’s with a fair market
value equal to 20% of their deferred cash compensation as of the closing date of the financing (the “20% Deferral”). The number
of RSU’s to be granted will be calculated based on the closing price of the Company’s common stock on the closing date of
the financing and will vest one-year from the date of grant. There was no share-based compensation expense recorded for the three and
six months ended June 30, 2025 and 2024 pertaining to the 20% Deferral as the terms are unknown and are based on a future performance
trigger. As of June 30, 2025 and December 31, 2024, we have accrued $

Of such amount, two current members of our Board and one former member of our Board invested $225,000 in aggregate (see Note 6).
Moreover, on February 18, 2022, we entered into convertible note purchase agreements with sixteen (16) accredited investors, including five (5) members of our Board that participated on the same terms as other accredited investors, in the aggregate principal amount of $341,632. Of such amount, three current members of our Board and two former members of our Board invested $155,000 in aggregate (see Note 6).

About Mosaic
We are a development-stage biotechnology company focused on advancing and eventually commercializing immunotherapies for the treatment of cancer. We have historically advanced early-stage product candidates and we are pursuing new product candidates and platforms to build a new pipeline based on our understanding of immunotherapies.
As part of our strategy, on April 26, 2024, we entered into a binding term sheet (“Binding Term Sheet”) with Oncotelic Therapeutics, Inc.(“Oncotelic”) pursuant to which we intend to acquire (i) certain rights to Oncotelic’s clinical stage necroptosis cancer therapies associated with its vascular disruptive agents (“VDAs”) and related regulatory and clinical packages, and (ii) non-exclusive access to its proprietary Artificial Intelligence (“AI”) technologies for identifying immunotherapy combinations, in exchange for shares of our common stock valued at $15.0 million upon execution of the definitive agreement, or a combination of common stock and preferred stock to be determined by the parties, along with additional milestones allowing Oncotelic to earn up to an additional $15.0 million in shares of common stock that would be valued at the time of issuance, if earned. Pursuant to the Binding Term Sheet, we and Oncotelic agreed to negotiate in good faith towards the execution of a definitive agreement and the closing of the transaction, which is subject to customary due diligence and other conditions, including obtaining shareholder approval for the transaction and receiving waivers from our holders of Convertible Notes representing at least 90% of the principal amount outstanding from any payment that would become due and payable upon a corporate transaction as contemplated under the Binding Term Sheet. The Binding Term Sheet expired on June 30, 2025.
| 17 |
On November 18, 2024, we entered into an unsecured convertible promissory note (“Note Purchase Agreement”) with an accredited investor (“Investor”) for proceeds of up to $200,000 to be used for general corporate purposes. On December 4, 2024, the Company received $200,000 under the note purchase agreement and issued an unsecured convertible note bearing interest at a rate of 5% per annum that is due and payable upon closing a financing of at least $10.0 million or convertible into shares of common stock of the Company, at the sole discretion of the accredited investor. The number of shares of common stock to be issued, if converted, would be equal to the unpaid principal amount and accrued and unpaid interest thereon divided by the closing price of our common stock on the date that is one day prior to such election.
Critical Accounting Policies and Estimates
Our unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which require us to make estimates and judgments that significantly affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates, and such differences could affect the results of operations reported in future periods. During the six months ended June 30, 2025, there have been no material changes to the Company’s significant accounting policies as compared to the significant accounting policies disclosed in Note 2 – Summary of Significant Accounting Policies included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.
Results of Operation
Three Months Ended June 30, 2025 and 2024:
Research and Development Expenses
Research and development expenses of approximately $16,000 for the three months ended June 30, 2025 are primarily related to salaries and related costs for personnel in research and development functions. The decrease in research and development expenses of approximately $45,000 for the three months ended June 30, 2025 as compared to the same prior year period was primarily due to a decrease in payroll and related costs due to a reduced time commitment by certain employees.
General and Administrative Expenses
General and administrative expenses of approximately $133,000 for the three months ended June 30, 2025 consist principally of salaries and related costs for personnel and consultants in executive and administrative functions of approximately $112,000, accounting and filing fees of approximately $11,000, director and officer insurance of approximately $8,000, and other expenses of approximately $2,000. The decrease in general and administrative expenses of approximately $81,000 for the three months ended June 30, 2025 as compared to the same prior year period was primarily due to (i) a decrease in payroll and related expenses of approximately $58,000 due to a reduced time commitment by certain employees, (ii) a decrease in accounting and filing fees of approximately $17,000 due to timing of services provided and (iii) a decrease in other expenses of approximately $6,000.
Other Income (Expense)
Interest Expense and Accretion to Redemption Value on Convertible Notes
Interest expense of approximately $21,000 and $19,000 for the three months ended June 30, 2025 and 2024, respectively, represents interest expense on convertible notes and loan payables.
| 18 |
Six Months Ended June 30, 2025 and 2024:
Research and Development Expenses
Research and development expenses of approximately $32,000 for the six months ended June 30, 2025 are primarily related to salaries and related costs for personnel in research and development functions. The decrease in research and development expenses of approximately $96,000 for the six months ended June 30, 2025 as compared to the same prior year period was primarily due to a decrease in payroll and related costs due to a reduced time commitment by certain employees.
General and Administrative Expenses
General and administrative expenses of approximately $292,000 for the six months ended June 30, 2025 consist principally of salaries and related costs for personnel and consultants in executive and administrative functions of approximately $221,000, accounting and filing fees of approximately $48,000, director and officer insurance of approximately $16,000, and other expenses of approximately $7,000. The decrease in general and administrative expenses of approximately $123,000 for the six months ended June 30, 2025 as compared to the same prior year period was primarily due to (i) a decrease in payroll and related expenses of approximately $125,000 due to a reduced time commitment by certain employees, (ii) a decrease in other expenses of approximately $7,000 offset by an increase in accounting and filing fees of approximately $9,000 due to timing of services provided.
Other Income (Expense)
Master Services Agreement with Oncotelic
On July 1, 2024, we entered into a Master Services Agreement with Oncotelic whereby we perform advisory and related services in connection with studies and projects. For the six months ended June 30, 2025, we earned $14,000 for advisory and related services which is recorded in other income in the accompanying unaudited condensed consolidated statements of operations.
Interest Expense and Accretion to Redemption Value on Convertible Notes
Interest expense of approximately $41,000 and $38,000 for the six months ended June 30, 2025 and 2024, respectively, represents interest expense on convertible notes and loan payables.
Accretion to redemption value on convertible notes of approximately $1,000 for the six months ended June 30, 2024 pertains to the accretion of the convertible notes to their redemption value using the effective interest method. The Convertible Notes have been accreted to their full redemption value as of March 31, 2024.
Liquidity and Capital Resources
As of June 30, 2025, we had cash and cash equivalents of approximately $54,000. Our ability to continue our operations is highly dependent on our ability to raise capital to fund future operations. We anticipate, based on currently proposed plans and assumptions, that our cash on hand will not satisfy our operational and capital requirements through twelve months from the filing date of this Annual Report.
Our primary uses of capital to date are primarily related to payroll, consulting and related costs, corporate formation and ongoing public company expenses, audit fees, fees associated with license agreements, including patent-related expenses, and costs of the reverse merger. Pending our ability to identify new product candidates and license or acquire those rights, then on a go forward basis, we will need significant additional capital to support our research and development efforts, compensation and related expenses, and hiring additional staff (including clinical, scientific, operational, financial, and management personnel) and to reduce our current liabilities. Pending our ability to identify new product candidates and license or acquire those rights, we would expect to incur substantial expenditures in the foreseeable future for the research and development of new potential product candidates, provided we are able to raise sufficient capital to advance these technologies and technologies under the Binding Term Sheet, as noted below.

On July 1, 2024, we entered into a Master Services Agreement with Oncotelic whereby we perform advisory and related services in connection with studies and projects. During the six months ended June 30, 2025, we earned $14,000 for advisory and related services which is recorded in other income in the accompanying unaudited condensed consolidated statements of operations.
On November 18, 2024, we entered into an unsecured convertible promissory note (“Note Purchase Agreement”) with an accredited investor (“Investor”) for proceeds of up to $200,000 to be used for general corporate purposes. On December 4, 2024, the Company received $200,000 under the note purchase agreement and issued an unsecured convertible note bearing interest at a rate of 5% per annum that is due and payable upon closing a financing of at least $10.0 million or convertible into shares of common stock of the Company, at the sole discretion of the accredited investor. The number of shares of common stock to be issued, if converted, would be equal to the unpaid principal amount and accrued and unpaid interest thereon divided by the closing price of our common stock on the date that is one day prior to such election.
We plan to continue to fund losses from operations and future funding needs through our cash on hand and future potential equity and/or debt offerings. There are a number of uncertainties associated with our ability to raise additional capital and we have no current arrangements with respect to any additional financing. If we raise funds from the issuance of equity securities (which will be challenging in light of current market conditions combined with our limited technologies), substantial dilution to our existing stockholders would likely result. If we raise additional funds by incurring debt financing (also challenging in light of current market conditions combined with our limited technologies), the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict our ability to operate our business. Since the closing date of the Reverse Merger, our limited cash position has required us to perform only limited development activities and to delay and scale back our development programs and other activities to remain afloat. If we continue to have insufficient funds, we may be required to cease our operations altogether.
In addition, the continuation of disruptions caused by COVID-19 or other related variants, broad-based inflation, and various economic indicators that the United States economy may be entering a recession in upcoming quarters may cause investors to slow down or delay their decision to deploy capital which will adversely impact our ability to fund future operations. Consequently, there can be no assurance that any additional financing on commercially reasonable terms, or at all, will be available when needed. If we are unable to raise additional capital and continue to have insufficient funds, we may be required to cease our operations altogether. The above matters raise substantial doubt regarding our ability to continue as a going concern.
