Notes to Condensed Financial Statements

(Unaudited)

NOTE 1 — DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business

Miromatrix Medical Inc. (the “Company”) is a life sciences company pioneering a novel technology for bioengineering fully transplantable organs to help save and improve patients’ lives. Founded in 2009, the Company is one of a small group of companies at the forefront of developing alternatives to human-donor organ transplants, and within this small group of companies there are important differences between the technologies being developed. The Company’s proprietary technology is a scalable platform that uses a two-step method of decellularization and recellularization designed to remove the porcine cells from the organs obtained from pigs and replace them with unmodified human cells. The Company’s initial development focus is on bioengineering livers and kidneys, and the Company’s technology platform is also applicable to bioengineering other organs including hearts, lungs and pancreases. The Company has collaborations with Baxter International Inc. (“Baxter”), CareDx, Inc. (“CareDx”), the Mayo Clinic, the Mount Sinai Health System and the Texas Heart Institute, and we have received strategic investments from Baxter, CareDx and DaVita Inc.

Basis of Preparation

The accompanying unaudited condensed financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules of the United States (“U.S.”) Securities and Exchange Commission applicable to interim reports of companies filing as a smaller reporting company. These condensed financial statements should be read in conjunction with the audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

In the opinion of management, the accompanying condensed financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, stockholders’ equity and cash flows for the interim periods but are not necessarily indicative of the results of operations or cash flows to be anticipated for the full year 2023 or any future period. The Company has evaluated subsequent events occurring after the date of the condensed financial statements for events requiring recording or disclosure in the condensed financial statements.

Reclassifications

Certain reclassifications to previously reported financial information on the Condensed Balance Sheets and Condensed Statements of Operations have been made to conform to the current period presentation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires 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 revenues and expenses during the reporting period. Actual results could differ from those estimates.

Employee Retention Credit

Under the provisions of the extension of the Coronavirus Aid, Relief, and Economic Security Act, the Company is eligible for a refundable employee retention credit subject to satisfaction of certain eligibility criteria. The Company qualified for the employee retention credit for the first three quarters of 2020 and the second and third quarters of 2021. The Company recognized $527,143 during the six months ended June 30, 2023, consistent with guidance from International Accounting Standards 20, Accounting for Government Grants and Disclosure of Government Assistance, where the Company must have substantially met the program’s eligibility conditions to record revenue. It was reported as an employee retention credit receivable on the Condensed Balance Sheet and employee retention credit other income on the Condensed Statement of Operations for the six months ended June 30, 2023.

Table of Contents

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these condensed financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

The FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments and an updated ASU 2018-19 that clarifies the scope of the standard in the amendments in ASU 2016-13. This guidance introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. Financial instruments impacted are trade and other receivables, held-to-maturity debt securities, loans and other instruments. The Company adopted the standard effective January 1, 2023, using the modified retrospective approach. The adoption did not have an impact on the Company's financial statements.

NOTE 2 — GOING CONCERN

The accompanying condensed financial statements have been prepared on the basis that the Company will continue as a going concern. The Company has incurred losses since inception, negative cash flows from operations, and had an accumulated deficit of approximately $118.0 million as of June 30, 2023. The Company does not have adequate liquidity to fund its operations for at least twelve months from the issuance of these financial statements without raising additional capital and such actions are not solely within the control of the Company. If the Company is unable to raise additional capital, management believes planned expenditures may need to be reduced in order to extend the time period that existing resources can fund the Company’s operations. To date, the Company has funded its operations through the issuance of equity and debt securities, and the receipt of grants. The Company intends to fund ongoing operations by utilizing its current cash, cash equivalents and short-term investments on hand, and by exploring various dilutive and non-dilutive sources of funding, including equity financings, debt financings, strategic partnerships and collaborations, as well as other sources. If the Company is unable to obtain additional capital, it would have a material adverse effect on the operations of the Company and the development of its technology, and the Company may have to cease operations altogether. These factors raise substantial doubt about the Company’s ability to continue as a going concern.

NOTE 3 — FAIR VALUE MEASUREMENT

The fair value of the Company’s financial instruments reflects the amount that the Company estimates that it would receive in connection with the sale of an asset or paid in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). The Company uses a three-tier valuation hierarchy based upon observable and non-observable inputs to measure fair value:

Level 1: Inputs that include quoted prices in active markets for identical assets and liabilities.

Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company classifies cash and cash equivalents, as well as restricted cash, as Level 1 in the fair value hierarchy.

Table of Contents

The Company classifies its investments in U.S. Treasury notes as Level 1 in the fair value hierarchy. While the market for these securities are highly liquid and active, quoted prices for these securities may at times be derived from pricing models which use observable inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and other reference data including market research publications.

NOTE 4 — INVESTMENTS

The Company currently invests its excess cash in U.S. Treasury securities. The Company intends and has the ability to hold these investments to maturity. Securities with original maturity dates of more than three months are reported as held-to-maturity investments and are recorded at amortized cost, which approximates fair value due to the negligible risk of changes in value due to interest rates. All investments held as of June 30, 2023 had contractual maturities of less than one year.

The amortized cost and estimated fair values of the Company’s investments as of June 30, 2023 are as follows:


	Amortized		Unrealized		Unrealized		Fair
	Cost		Holding Gains		Holding Losses		Value
Short-term:
U.S. Treasury notes	$	15,828,281	$	—	$	50,181	$	15,778,100
Total	$	15,828,281	$	—	$	50,181	$	15,778,100

NOTE 5 — PROPERTY AND EQUIPMENT, NET

Property and equipment consisted of the following as of:


	June 30,		December 31,
	2023		2022
Lab equipment	$	2,009,971	$	1,977,436

NOTE 7 — DEBT

In January 2019, the Company issued the Regents of the University of Minnesota (the “University”) a promissory note in the amount of $385,997 in satisfaction of the Company’s minimum royalty obligation for the year ended December 31, 2018. The note bears interest at 6.0% per annum, compounded annually, and is due on January 31, 2025. As of both June 30, 2023 and December 31, 2022, the balance outstanding on this loan was $385,997. In addition, the Company issued the University a 10-year warrant to purchase 20,587 shares of the Company’s common stock at an exercise price of $3.75 per share, which remained outstanding through June 30, 2023.

Future principal maturities for debt were as follows:

NOTE 8 — EQUITY

Common Stock

The Company is authorized to issue 190,000,000 shares of common stock, with a par value of $0.00001. Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of common stockholders. Subject to preferences that may be applicable to any outstanding preferred shares, each share of common stock is entitled to share pro rata in any distributions. In any distribution of capital assets, holders of common stock are entitled to receive pro rata the assets remaining after payment of liabilities and liquidation preferences on any outstanding preferred stock.

In March 2023, the Company completed a public offering pursuant to which it sold an aggregate of 6,250,000 shares of the Company’s common stock at a public offering price of $1.60 per share, resulting in gross proceeds of $10 million. The offering closed on March 10, 2023, resulting in net proceeds of approximately $8.8 million, after deducting underwriting discounts and commissions and other offering expenses.

The Company previously capitalized $232,899 of deferred offering costs relating to the $200 million shelf registration statement declared effective on July 11, 2022. When the Company completed the public offering in March 2023, $11,645 was reclassified to additional paid-in capital on the Balance Sheet and $221,254 was written-off to general and administrative expenses in the Statement of Operations, on a pro-rata basis.

NOTE 12 — NET LOSS PER SHARE

Basic net loss per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is calculated by dividing the weighted average number of common shares outstanding, after taking into consideration all dilutive potential shares outstanding during the period. Due to the existence of net losses for the three and six months ended June 30, 2023 and 2022, basic and diluted net loss per share were the same, as the effect of potentially dilutive securities would have been anti-dilutive.

The following potentially dilutive securities outstanding have been excluded from the computations of diluted weighted average shares outstanding because such securities would have had an antidilutive impact due to losses reported for the periods presented:


	Three and Six Months Ended June 30,

Overview

We are a life sciences company pioneering a novel technology for bioengineering fully transplantable organs to help save and improve patients’ lives. Founded in 2009, we are one of a small group of companies at the forefront of developing alternatives to human-donor organ transplants, and within this small group of companies there are important differences between the technologies being developed. Our proprietary technology is a scalable platform that uses a two-step method of decellularization and recellularization designed to remove the porcine cells from the organs obtained from pigs and replace them with unmodified human cells. Our initial development focus is on bioengineering livers and kidneys, and our technology platform is also applicable to bioengineering other organs including hearts, lungs and pancreases. We have collaborations with the Mayo Clinic, Baxter, CareDx, Mount Sinai and the Texas Heart Institute, and have received strategic investments from Baxter, CareDx and DaVita.

Substantially all of our revenue to date has been generated by sales of and royalties we received from acellular biologic surgical products, which we spun out as Reprise Biomedical, Inc. (“Reprise”) effective June 30, 2019. We subsequently divested our minority ownership stake in Reprise in March 2021. We have continued to receive royalties on the sales of these products by Reprise. Our revenue for the three and six months ended June 30, 2023 was $8,517 and $16,498, respectively, consisting entirely of licensing revenue. Our net loss for the three and six months ended June 30, 2023 was $6,530,420 and $14,010,572, respectively. We have not been profitable since inception and as of June 30, 2023, we had an accumulated deficit of $118,022,483.

Table of Contents

Our product pipeline consists of three active programs, as described below:

●

miroliverELAP_®, our External Liver Assist Product (“ELAP”) designed to provide liver dialysis for acute liver failure patients.

●

miroliver, our fully implantable bioengineered liver intended to treat patients with acute and chronic liver failure.

●

mirokidney, our fully implantable bioengineered kidney intended to treat patients with end-stage renal disease.

Recent Developments

In the fourth quarter of 2022, we filed an IND application for our miroliverELAP to the FDA. In response to the IND application, we received a clinical hold letter from the FDA in January 2023 identifying certain nonclinical and clinical deficiencies and requesting responsive information, including, among other things, new toxicology studies in an appropriate animal model, biocompatibility studies, as well as various validations to be provided in our IND application. We plan to submit our complete response to the clinical hold letter to the FDA in the second half of 2023. If our complete response addresses the deficiencies to the FDA’s satisfaction and does not raise new concerns regarding risks to subjects, we expect the FDA will lift the clinical hold and we then intend to initiate a first-in-human, phase 1 clinical trial shortly thereafter. We have reallocated resources previously intended for miroliver and mirokidney, our fully implantable bioengineered liver and kidney programs, to miroliverELAP, which will likely delay the preclinical development of miroliver and mirokidney.

Components of Our Results of Operations

Licensing Revenue

For the periods presented, all of our revenue consists of licensing revenue pursuant to our license agreement with Reprise. Revenue pursuant to this agreement is recognized at the later of (i) when the related sales occur after the minimum guarantee is satisfied, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). Due to future uncertainty regarding the collectability of the 2021 and 2023 minimum royalties from Reprise, we determined the contract did not meet the requirements of Accounting Standards Codification, Topic 606, Revenue from Contracts with Customers (“ASC 606”); therefore, we did not record revenues or a receivable.

Cost of Goods Sold

Cost of goods sold relates to our license agreement with the University of Minnesota (the “University”), pursuant to which we owe the University royalties on our revenues, which are subject to annual minimum payments.

Gross Loss

Our gross loss is calculated by subtracting our cost of goods sold from our revenue.

Research and Development Expenses

Research and development expenses consist primarily of engineering, product development, consulting services, materials, depreciation and other costs associated with products and technologies in development. These expenses include payroll and related expenses, consulting expenses, laboratory supplies, and amounts incurred under certain collaborative agreements. Expenditures for research and development activities are charged to operations as incurred.

We expect research and development expenses to increase in the future, as we continue the development of our current product candidates. Research and development expenses will be dependent upon such factors including the results of our preclinical and clinical trials, and the number of product candidates under development.

Table of Contents

Regulatory and Clinical Expenses

Regulatory and clinical expenses include costs for developing our regulatory and clinical study strategies for our product candidates. These expenses include payroll and related expenses and consulting expenses. We expect regulatory and clinical expenses will be dependent on the size and duration of any clinical programs that we may initiate.

Quality Expenses

Quality expenses relate to costs of systems and procedures to develop a manufacturing facility that is compliant with Current Good Manufacturing Practices. These expenses include payroll and related expenses. We expect quality expenses to increase in future years as we continue to develop the process and systems needed to produce our product candidates.

General and Administrative Expenses

General and administrative expenses include costs for our executive, accounting and human resources functions. Costs consist primarily of payroll and related expenses, professional service fees related to accounting, legal and other contract and administrative services and related infrastructure expenses.

Interest Income

Interest income consists of interest earned on our cash and cash equivalents and U.S. Treasury securities.

Interest Expense

Interest expense consists of interest under our loan agreements. See “— Liquidity and Capital Resources.”

Licensing Revenue

Licensing revenue was $8,517 for the three months ended June 30, 2023 and $3,952 for the three months ended June 30, 2022, an increase of $4,565, or 115.5%. The licensing revenue is a result of the license agreement with Reprise. The remainder of minimum royalties due from Reprise for 2023 are due in January 2024. The remainder of the minimum royalties due from Reprise for 2021 have been deferred to 2023. Due to the uncertainty regarding the collectability of the 2021 and 2023 minimum royalties from Reprise, we determined the contract did not meet the requirements of ASC 606; therefore, we did not record revenues or a receivable.

Cost of Goods Sold

Cost of goods sold was $125,000 for both the three months ended June 30, 2023 and 2022. Cost of goods sold relates to the minimum royalty due to the University under our license agreement.

Gross Loss

Gross loss was $116,483 for the three months ended June 30, 2023 and $121,048 for the three months ended June 30, 2022, a decrease of $4,565, or 3.8%.

The decrease was primarily due to a lab supply expense decrease of $1,315,041, consulting expense decrease of $234,266 and office expense decrease of $96,172. The decrease was partially offset by a headcount increase which resulted in an increase in payroll expense of $257,238 and other expense increase of $21,232.

Regulatory and Clinical

Regulatory and clinical expenses were $397,448 for the three months ended June 30, 2023 and $419,394 for the three months ended June 30, 2022, a decrease of $21,946, or 5.2%. The decrease was primarily due to lower consulting expenses.

Quality

Quality expenses were $515,575 for the three months ended June 30, 2023 and $517,333 for the three months ended June 30, 2022, a decrease of $1,758, or 0.3%.

General and Administrative

General and administrative expenses were $2,037,682 for the three months ended June 30, 2023 and $2,188,460 for the three months ended June 30, 2022, a decrease of $150,778, or 6.9%. The decrease was primarily due to professional service fee decrease of $85,450, office expense decrease of $44,218, travel and entertainment expense decrease of $34,549, consulting expense decrease of $29,037 and other expense decrease of $2,849. The decrease was partially offset by taxes and licenses expense increase of $45,325.

Interest Income

Interest income was $166,162 for the three months ended June 30, 2023 and $61,078 for the three months ended June 30, 2022, an increase of $105,084, or 172.0%. The increase was primarily due to U.S. Treasury securities purchased during the second quarter of 2022 and the second quarter of 2023 with cash received from our initial public offering and our secondary public offering, which was completed in the first quarter of 2023.

Licensing Revenue

Licensing revenue was $16,498 for the six months ended June 30, 2023 and $10,720 for the six months ended June 30, 2022, an increase of $5,778, or 53.9%. The licensing revenue is a result of the license agreement with Reprise. The remainder of minimum royalties due from Reprise for 2023 are due in January 2024. The remainder of the minimum royalties due from Reprise for 2021 have been deferred to 2023. Due to the uncertainty regarding the collectability of the 2021 and 2023 minimum royalties from Reprise, we determined the contract did not meet the requirements of ASC 606; therefore, we did not record revenues or a receivable.

Cost of Goods Sold

Cost of goods sold was $250,000 for both the six months ended June 30, 2023 and 2022. Cost of goods sold relates to the minimum royalty due to the University under our license agreement.

Gross Loss

Gross loss was $233,502 for the six months ended June 30, 2023 and $239,280 for the six months ended June 30, 2022, a decrease of $5,778, or 2.4%.

Research and Development

Research and development expenses were $8,013,342 for the six months ended June 30, 2023 and $8,994,899 for the six months ended June 30, 2022, a decrease of $981,557, or 10.9%. The decrease was primarily due to lab supply expense decrease of $1,512,769, contract services expense decrease of $151,181, consulting expense decrease of $87,436, office expense decrease of $77,418 and travel and entertainment expense decrease of $22,664. The decrease was partially offset by payroll expense increase of $806,397 and other expense increase of $63,514.

Table of Contents

Regulatory and Clinical

Regulatory and clinical expenses were $803,763 for the six months ended June 30, 2023 and $774,632 for the six months ended June 30, 2022, an increase of $29,131, or 3.8%. The increase was primarily due to a headcount increase which resulted in an increase in payroll expense of $85,199, partially offset by consulting expense decrease of $30,940, office expense decrease of $7,951, contract services expense decrease of $7,658, travel and entertainment expense decrease of $6,087 and other expense decrease of $3,432.

Quality

Quality expenses were $1,098,917 for the six months ended June 30, 2023 and $958,268 for the six months ended June 30, 2022, an increase of $140,649, or 14.7%. The increase was primarily due to an increase in lab supply expense of $341,972 and other expense increase of $22,982. The increase was partially offset by a decrease in payroll expense of $143,708, consulting expense decrease of $70,882, contract services expense decrease of $7,652 and office expense decrease of $2,063.

General and Administrative

General and administrative expenses were $4,637,917 for the six months ended June 30, 2023 and $4,461,017 for the six months ended June 30, 2022, an increase of $176,900, or 4.0%. The increase was primarily due to deferred offering costs write-off of $221,254, payroll expense increase of $122,278, shareholder expense increase of $7,420 and professional service expense increase of $3,551. The increase was partially offset by travel and entertainment expense decrease of $59,875, office expense decrease of $45,842, insurance expense decrease of $34,059, consulting expense decrease of $31,604 and other expense decrease of $6,223.

Interest Income

Interest income was $268,139 for the six months ended June 30, 2023 and $61,848 for the six months ended June 30, 2022, an increase of $206,291, or 333.5%. The increase was primarily due to U.S. Treasury securities purchased during the second quarter of 2022 and the second quarter of 2023 with cash received from our initial public offering and our secondary public offering, which was completed in the first quarter of 2023.

Interest Expense

Interest expense was $18,413 for the six months ended June 30, 2023 and $19,690 for the six months ended June 30, 2022, a decrease of $1,277, or 6.5%.

Employee Retention Credit

Employee retention credit income was $527,143 for the six months ended June 30, 2023. This is a refundable credit against certain employment taxes recognized under the provisions of the Coronavirus Aid, Relief, and Economic Security Act.

Liquidity and Capital Resources

We have incurred net losses since our inception. For the three months ended June 30, 2023 and 2022, we incurred net losses of $6,530,420 and $8,182,189, respectively. For the six months ended June 30, 2023 and 2022, we incurred net losses of $14,010,572 and $15,385,938, respectively. As of June 30, 2023, we had an accumulated deficit of $118,022,483.

Table of Contents

We expect to incur additional losses in the near future, and we expect our expenses to increase in connection with our ongoing activities, particularly as we continue to develop our bioengineered organs, conduct clinical trials and other studies for our bioengineered organs, seek regulatory clearances or approvals for miroliverELAP, mirokidney and miroliver, continue preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights, invest in our infrastructure to support our future manufacturing and other activities, and incur costs associated with operating as a public company in the U.S. The timing and amount of our operating expenditures will depend largely on our ability to, among other things:

●

advance clinical development of our product candidates;

●

manufacture, or have manufactured on our behalf, our preclinical and clinical materials and develop processes for commercial manufacturing of any product candidates that may receive regulatory approval;

●

seek regulatory approvals for any product candidates that successfully complete clinical trials;

●

establish a sales, marketing, medical affairs and distribution infrastructure to commercialize any product candidates for which we may obtain marketing approval and intend to commercialize on our own;

●

establish collaborations to commercialize any product candidates for which we may obtain marketing approval but do not intend to commercialize on our own;

●

expand our operational, financial and management systems and hire additional personnel, including personnel to support our clinical development, quality control, research and development, manufacturing and commercialization efforts, our general and administrative activities and our operations as a public company; and

●

obtain new intellectual property and maintain, expand and protect our intellectual property portfolio.

Sources of Liquidity

The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. To date, we have primarily financed our operations through equity and debt financings, including public offerings of our common stock, as well as research grants. We do not have adequate liquidity to fund our operations for at least twelve months from the issuance of these financial statements without raising additional capital and such actions are not solely within our control. If we are unable to raise additional capital, we believe planned expenditures may need to be reduced in order to extend the time period that existing resources can fund our operations. We have based this estimate on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. As of June 30, 2023, we had cash and cash equivalents of $4,571,777 and short-term investments of $15,828,281.

Until such time, if ever, as we can generate substantial revenue from sales of our bioengineered organs, we expect to finance our cash needs through a combination of equity offerings, debt financings, strategic partnerships and collaborations, as well as other sources. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Additional capital may not be available when needed, on reasonable terms, or at all, and our ability to raise additional capital may be adversely impacted by factors not solely within our control. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we may be required to delay, curtail or discontinue our product development or future commercialization efforts, or grant rights to develop and market products that we would otherwise prefer to develop and market ourselves.

Debt Financing

In January 2019, we issued the University a promissory note in the amount of $385,997 in satisfaction of our minimum royalty obligation under the license agreement with the University for the year ended December 31, 2018. The note bears interest at 6% per annum, compounded annually, and is due on January 31, 2025. In addition, we issued the University a 10-year warrant to purchase 20,587 shares of our common stock at an exercise price of $3.75 per share. As of both June 30, 2023 and December 31, 2022, the principal outstanding on this loan was $385,997.

Table of Contents

Registration Statement

We filed a Registration Statement on Form S-3 with the SEC on July 1, 2022, which was declared effective on July 11, 2022 (the “Registration Statement”). The Registration Statement registered the offer and sale of an indeterminate number of shares of common stock and preferred stock, an indeterminate principal amount of debt securities and an indeterminate number of warrants to purchase common stock, preferred stock, and various series of debt securities and warrants to purchase any of such securities, having an aggregate initial offering price of $200.0 million.

Equity Distribution Agreement

On July 1, 2022, we entered into an Equity Distribution Agreement with Piper Sandler & Co. (“Piper Sandler”). The Equity Distribution Agreement provides that, upon the terms and subject to the conditions set forth therein, we may issue and sell through Piper Sandler, acting as the sales agent, shares of our common stock having an aggregate offering price of up to $50.0 million. We have no obligation to sell any such shares under the Equity Distribution Agreement. The sale of the shares of our common stock by Piper Sandler, if any, will be effected pursuant to the Registration Statement. We did not issue any shares under the Equity Distribution Agreement in the six months ended June 30, 2023.

Public Offering

In March 2023, we completed a public offering pursuant to which we sold an aggregate of 6,250,000 shares of our common stock at a public offering price of $1.60 per share. The offering closed on March 10, 2023, resulting in net proceeds of approximately $8.8 million, after deducting underwriting discounts and commissions and other offering expenses.

Employee Retention Credit

On July 31, 2023, we received cash payments totaling $457,143 of the $527,143 employee retention receivable.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not required for smaller reporting companies.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended June 30, 2023, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were not effective as of June 30, 2023 because of our previously reported material weaknesses in our internal control over financial reporting, which we describe in Part II, Item 9A of our Annual Report on Form 10-K for the year ended December 31, 2022.

Table of Contents

Management is committed to remediating its material weaknesses as promptly as possible and is in the process of implementing its remediation plan. We are in the process of designing, implementing, documenting and testing the effectiveness of our processes, procedures and internal controls over financial reporting. The material weakness cannot be considered completely remediated until the applicable internal controls over financial reporting have operated for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. We cannot reasonably assure we will be able to remediate the material weaknesses we have identified or avoid potential future material weaknesses.

Changes in Internal Control over Financial Reporting

As outlined above, due to the identification of the material weaknesses, we continued to design, implement, document and test the effectiveness of our processes, procedures and internal controls over financial reporting. We made no other changes in our internal control over financial reporting that occurred during the fiscal quarter of 2023 covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

We are not presently a party to any litigation the outcome of which, we believe, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, cash flows or financial condition.

Item 1A. Risk Factors

This Quarterly Report on Form 10-Q should be read in conjunction with the risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the SEC on March 31, 2023. Other than as set forth below, there have been no material changes to the risk factors disclosed under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

As a result of our limited financial liquidity, we have expressed substantial doubt regarding our ability to continue as a “going concern.”

As a result of our current limited financial liquidity, the notes accompanying our unaudited interim condensed financial statements, which are included as part of this report, contain a statement concerning our ability to continue as a “going concern.” Our limited liquidity could make it more difficult for us to secure additional financing or enter into strategic relationships on terms acceptable to us, if at all, and may materially and adversely affect the terms of any financing that we may obtain and our public stock price generally.

We have incurred losses since inception, negative cash flows from operations, and had an accumulated deficit of approximately $118.0 million as of June 30, 2023. The Company does not have adequate liquidity to fund its operations for at least twelve months from the issuance of these financial statements without raising additional capital and such actions are not solely within the control of the Company. If the Company is unable to raise additional capital, management believes planned expenditures may need to be reduced in order to extend the time period that existing resources can fund the Company’s operations. To date, the Company has funded its operations through the issuance of equity and debt securities, and the receipt of grants. The Company intends to fund ongoing operations by utilizing its current cash, cash equivalents and short-term investments on hand, and by exploring various dilutive and non-dilutive sources of funding, including equity financings, debt financings, strategic partnerships and collaborations, as well as other sources. If the Company is unable to obtain additional capital on commercially reasonable terms, or at all, it would have a material adverse effect on the operations of the Company and the development of its technology, and the Company may have to cease operations altogether. These factors raise substantial doubt about the Company’s ability to continue as a going concern.

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

Unregistered Sales of Equity Securities

None.

Use of Proceeds

On June 28, 2021, we completed our initial public offering on common stock (the “IPO”) in which we sold 5,520,000 shares of common stock at a public offering price of $9.00 per share. The offer and sale of all of the shares in the IPO were registered under the Securities Act pursuant to the Company’s registration statement on Form S-1 (File No. 333-256649), as amended, which was declared effective on June 23, 2021 pursuant to Rule 462(b) under the Securities Act. Craig-Hallum Capital Group acted as sole managing underwriter for the IPO.

We received net proceeds of approximately $44.5 million from the IPO, after paying $342,500 of fees and expenses of Craig-Hallum. We are using the net proceeds from the IPO as follows:

●

between approximately $34.8 million to $40.0 million to fund our research and development activities, including, but not limited to, our Phase I trial for the miroliverELAP product and certain pre-clinical trials for our bioengineered organs;

●

between approximately $3.0 million and $4.0 million to fund the full cost of constructing a new facility; and

●

the remaining funds for working capital and general corporate purposes.

Pending the uses of proceeds above, we have invested in a variety of capital preservation instruments, including short-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the United States government.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures

Not applicable.

Item 5. Other Information

During the three months ended June 30, 2023, no director or officer of the Company adopted, modified or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.

CERTIFICATION OF CHIEF EXECUTIVE OFFICER

I, Jeffrey Ross, certify that:

I have reviewed this quarterly report on Form 10-Q of Miromatrix Medical Inc.;

DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2023
DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
Basis of Preparation	Basis of Preparation The accompanying unaudited condensed financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules of the United States (“U.S.”) Securities and Exchange Commission applicable to interim reports of companies filing as a smaller reporting company. These condensed financial statements should be read in conjunction with the audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022. In the opinion of management, the accompanying condensed financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, stockholders’ equity and cash flows for the interim periods but are not necessarily indicative of the results of operations or cash flows to be anticipated for the full year 2023 or any future period. The Company has evaluated subsequent events occurring after the date of the condensed financial statements for events requiring recording or disclosure in the condensed financial statements.
Reclassifications	Reclassifications Certain reclassifications to previously reported financial information on the Condensed Balance Sheets and Condensed Statements of Operations have been made to conform to the current period presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires 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 revenues and expenses during the reporting period. Actual results could differ from those estimates.
Employee Retention Credit - CARES Act	Employee Retention Credit Under the provisions of the extension of the Coronavirus Aid, Relief, and Economic Security Act, the Company is eligible for a refundable employee retention credit subject to satisfaction of certain eligibility criteria. The Company qualified for the employee retention credit for the first three quarters of 2020 and the second and third quarters of 2021. The Company recognized $527,143 during the six months ended June 30, 2023, consistent with guidance from International Accounting Standards 20, Accounting for Government Grants and Disclosure of Government Assistance, where the Company must have substantially met the program’s eligibility conditions to record revenue. It was reported as an employee retention credit receivable on the Condensed Balance Sheet and employee retention credit other income on the Condensed Statement of Operations for the six months ended June 30, 2023.
Emerging Growth Company Status	Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these condensed financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.
Recently Adopted Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements The FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments and an updated ASU 2018-19 that clarifies the scope of the standard in the amendments in ASU 2016-13. This guidance introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. Financial instruments impacted are trade and other receivables, held-to-maturity debt securities, loans and other instruments. The Company adopted the standard effective January 1, 2023, using the modified retrospective approach. The adoption did not have an impact on the Company's financial statements.
