MIROMATRIX MEDICAL INC.

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 the Mayo Clinic, Mount Sinai Health System and the Texas Heart Institute, and has received strategic investments from Baxter International, Inc., CareDx, Inc. 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 and the rules of the United States (“U.S.”) Securities and Exchange Commission (“SEC”) 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, 2021. 

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 2022 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.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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.

Investments

The Company 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.

7

Deferred Offering Costs

Deferred offering costs are expenses directly related to the Shelf Registration Statement on Form S-3 filed with the SEC on July 1, 2022 and declared effective on July 11, 2022 (the “Shelf Registration”). These costs consist of legal, accounting, printing and filing fees that the Company has capitalized, including fees incurred by the independent registered public accounting firm directly related to the Shelf Registration. Deferred costs associated with the Shelf Registration will be reclassified to additional paid-in capital on a pro-rata basis when the Company completes offerings under the Shelf Registration. Any remaining deferred offering costs will be charged to the statement of operations at the earlier of when it becomes probable that the offering will not result in the receipt of proceeds from the issuance of securities or at the end of the three-year life of the Shelf Registration.

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 Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“ASC 842”), which requires lessees to recognize the assets and liabilities that arise from leases on the balance sheet. The standard also requires expanded disclosures to help financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. The Company adopted the new standard effective January 1, 2022 using the modified retrospective approach.

The Company determines if an arrangement is a lease at inception. Operating leases are included in right of use assets and lease liabilities on the condensed balance sheets. The right of use assets and lease liabilities are recognized as the present value of the future minimum lease payments over the lease term at commencement date. The right of use asset is also adjusted for any lease payments made and excludes lease incentives and initial direct costs incurred. As most leases do not provide an implicit rate, and the Company does not have a readily available incremental borrowing rate, the Company uses the interest rate available for the lowest-grade debt in the marketplace based on the information available at commencement date in determining the present value of future payments.

The standard provides a number of optional practical expedients in transition. The Company elected to exercise the package of practical expedients, which, among other things, allows the Company to carryforward the determining lease classification and lease term.

As a result of adopting the new standard, the Company recognized right of use assets of $1,882,696 and lease liabilities of $2,020,839 as of January 1, 2022. Certain amounts in the prior year financial statements have been reclassified for comparative purposes to conform to the presentation for the three and nine months ended September 30, 2022. Specifically, prior to the adoption of ASC 842, the Company presented capital leases together with long-term debt on the balance sheets. Financing leases (previously capital leases) is now presented separately on the balance sheets. In addition, prior to the adoption of ASC 842, the Company presented the non-cash change in deferred rent as deferred rent within the operating section of the statement of cash flows. This balance is now presented on the operating lease right of use asset line within the operating section of the statement of cash flows. The adoption of this standard did not have a material impact on income or cash flows. See Note 11 for further details.

8

Accounting Pronouncements Not Yet Adopted

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. There are various transition methods available upon adoption. As an emerging growth company, the Company is permitted to defer adoption until the private company adoption date of annual periods started after December 15, 2022. The Company is currently evaluating the impact of adoption on its financial statements.

NOTE 2 — 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 on September 30, 2022 had contractual maturities of less than one year.

The amortized cost and estimated fair values of the Company’s investments as of September 30, 2022 are as follows:

	Amortized		Unrealized		Unrealized		Fair
	Cost		Holding Gains		Holding Losses		Value
Short-term:
U.S. Treasury notes	$	26,003,087	$	—	$	259,547	$	25,743,540
Total	$	26,003,087	$	—	$	259,547	$	25,743,540

NOTE 3 — PROPERTY AND EQUIPMENT

Property and equipment consisted of the following as of:

	September 30,		December 31,
	2022		2021
Lab equipment	$	1,977,436	$	1,549,416
Leasehold improvements		3,371,915		3,239,307
Furniture, fixtures and computers		2,022,894		1,671,793
		7,372,245		6,460,516
Less accumulated depreciation and amortization		(1,556,217)		(868,790)
	$	5,816,028	$	5,591,726

Depreciation and amortization expense was $281,285 and $34,401 for the three months ended September 30, 2022 and 2021, respectively, and $817,792 and $93,575 for the nine months ended September 30, 2022 and 2021, respectively.

NOTE 4 — EQUITY METHOD INVESTMENT

The Company previously manufactured and sold acellular medical devices in the hernia mesh and wound care markets through a separately identifiable business unit (the “Acellular Business”). On June 30, 2019, the Acellular Business was spun-out to Reprise Biomedical, Inc. (“Reprise”). At the time of the spin-out and until November 15, 2020, the Company owned 4,500,000 shares of common stock of Reprise, which represented 45% ownership in Reprise. In November 2020, the Company sold 2,700,000 shares of common stock of Reprise for $3,000,000 and retained an 18% ownership interest in Reprise.

NOTE 6 — 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.

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 13 — 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 share is calculated by dividing net income by 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 nine months ended September 30, 2022 and 2021, 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 Nine Months Ended September 30,
	2022	2021
Common stock options outstanding	3,874,186	3,464,805
Common stock warrants	599,191	950,879

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, Mount Sinai and the Texas Heart Institute, and have received strategic investments from Baxter, CareDx and DaVita.

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 Biomedical, Inc. (“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 the uncertainty regarding the collectability of these minimum royalties from Reprise, the Company has set up an allowance to offset the entire remaining minimum royalty receivable amount.

17

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.

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 in absolute dollars to increase in the future as we develop our product candidates. We expect research and development expenses as a percentage of revenue to vary over time depending on the level and timing of new product development initiatives.

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.

Over time we expect our regulatory and clinical expenses to increase in absolute dollars as we develop our product candidates and move through various regulatory processes. We expect our regulatory and clinical expenses to decrease as a percentage of revenue primarily as, and to the extent, our revenue grows.

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 our quality expenses in absolute dollars 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, insurance and other contract and administrative services and related infrastructure expenses.

We expect that our general and administrative expenses in absolute dollars will increase as we expand our headcount to support our growth.

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.”

Regulatory and Clinical

Regulatory and clinical expenses were $381,903 for the three months ended September 30, 2022 and $105,208 for the three months ended September 30, 2021, an increase of $276,695, or 263.0%.

Quality expenses were $634,511 for the three months ended September 30, 2022 and $150,675 for the three months ended September 30, 2021, an increase of $483,836, or 321.1%. The increase was primarily due to a lab supply increase of $330,617 and consulting expense increase of $134,362.

General and Administrative

General and administrative expenses were $2,052,731 for the three months ended September 30, 2022 and $1,487,654 for the three months ended September 30, 2021, an increase of $565,077, or 38.0%. The increase was primarily due to a headcount increase which resulted in an increase in payroll expenses of $340,134, office expense increase of $168,024, and depreciation expense increase of $149,868. The increase was partially offset by consulting expense decrease of $73,184, insurance expense decrease of $52,109 and legal and accounting expense decrease of $44,752.

Interest Income

Interest income was $143,555 for the three months ended September 30, 2022 and $766 for the three months ended September 30, 2021, an increase of $142,789. The increase was primarily due to U.S. Treasury securities purchased during the second quarter of 2022 with cash received from our initial public offering (“IPO”).

Interest Expense

Interest expense was $15,325 for the three months ended September 30, 2022 and $15,255 for the three months ended September 30, 2021, a decrease of $70, or 0.5%.

Research Grants

Research grants were $0 for the three months ended September 30, 2022 and $115,069 for the three months ended September 30, 2021. The decrease in research grants was primarily due to decreases in pre-clinical contracting, resulting in lower grant funds.

Gain on Debt Extinguishment

The Company recognized a gain on the extinguishment of debt of $50,455 for the three months ended September 30, 2021 related to the forgiveness of our loan under the Small Business Administration’s Paycheck Protection Program.

Licensing Revenue

Licensing revenue was $23,115 for the nine months ended September 30, 2022 and $25,066 for the nine months ended September 30, 2021, an increase of $1,951, or 7.8%. The licensing revenue is a result of the licensing agreement with Reprise. The remainder of minimum royalties due from Reprise for 2020 and 2021 have been deferred to 2022 and 2023, respectively. The remainder of minimum royalties due from Reprise for 2022 are due in January 2023. Due to the uncertainty regarding the collectability of these minimum royalties from Reprise, the Company has set up an allowance to offset the entire remaining minimum royalty receivable amount.

Cost of Goods Sold

Cost of goods sold was $375,000 for both the nine months ended September 30, 2022 and 2021. Cost of goods sold relates to the minimum royalty due to the University under our license agreement.

Research and Development

Research and development expenses were $13,569,434 for the nine months ended September 30, 2022 and $7,698,786 for the nine months ended September 30, 2021, an increase of $5,870,648, or 76.3%. The increase was primarily due to lab supply increase of $2,551,888, headcount increase which resulted in an increase in payroll expenses of $1,543,323, contract pre-clinical cost increase of $632,372, consulting expense increase of $792,193 and depreciation expense increase of $277,662.

Regulatory and Clinical

Regulatory and clinical expenses were $1,156,535 for the nine months ended September 30, 2022 and $292,169 for the nine months ended September 30, 2021, an increase of $864,366, or 295.8%. The increase was primarily due to a headcount increase which resulted in an increase in payroll expenses of $577,700, as well as an increase in regulatory consulting and contracting expense of $202,568.

21

Quality

Quality expenses were $1,592,778 for the nine months ended September 30, 2022 and $322,719 for the nine months ended September 30, 2021, an increase of $1,270,059, or 393.5%. The increase was primarily due to a headcount increase which resulted in an increase in payroll expenses of $414,730, lab supply increase of $521,564 and consulting expense increase of $320,741.

General and Administrative

General and administrative expenses were $6,513,748 for the nine months ended September 30, 2022 and $2,836,850 for the nine months ended September 30, 2021, an increase of $3,676,898, or 129.6%. The increase was primarily due to a headcount increase which resulted in an increase in payroll expenses of $1,718,601, insurance expense increase of $523,972, office expense increase of $517,406, depreciation expense increase of $446,555, stockholder expense increase of $113,750, legal and accounting expense increase of $103,507 and consulting expense increase of $17,841. These increases can primarily be attributed to the cost of being a public company.

Interest Income

Interest income was $205,403 for the nine months ended September 30, 2022 and $851 for the nine months ended September 30, 2021, an increase of $204,552. The increase was primarily due to U.S. Treasury securities purchased during the second quarter of 2022 with cash received from the IPO.

Interest Expense

Interest expense was $35,015 for the nine months ended September 30, 2022 and $601,292 for the nine months ended September 30, 2021, a decrease of $566,277, or 94.2%. The decrease was primarily due to the interest expense on the $6,000,000 convertible promissory note issued to Cheshire MD Holdings, LLC ( the “Cheshire Note”) being converted to equity in June 2021, and therefore there was no interest expense related to the Cheshire Note in 2022 compared to 2021.

Amortization of Discount on Note

Amortization expense related to the Cheshire Note was $0 for the nine months ended September 30, 2022 and $62,638 for the nine months ended September 30, 2021. The decrease was due to the Cheshire Note being converted to equity in June 2021, and therefore there was no amortization expense related to the Cheshire Note in 2022 compared to 2021.

Change in Fair Value of Derivative

The fair value of the embedded derivative related to the Cheshire Note was $0 for the nine months ended September 30, 2022 and $246,962 for the nine months ended September 30, 2021. The decrease in the change in fair value of the embedded derivative was due to the Cheshire Note being converted to equity in June 2021.

Research Grants

Research grants were $0 for the nine months ended September 30, 2022 and $393,034 for the nine months ended September 30, 2021. The decrease in research grants was primarily due to decreases in pre-clinical contracting, resulting in lower grant funds.

Equity Loss in Affiliate

Equity loss in affiliate was $0 for the nine months ended September 30, 2022 and $223,633 for the nine months ended September 30, 2021. The Company sold its remaining ownership interest in Reprise in March 2021, eliminating the need to record any such losses for future periods, including the nine months ended September 30, 2022.

22

Gain on Sale of Equity Investment

The Company recognized a gain of $1,983,912 related to the sale of its remaining 1,800,000 shares of common stock of Reprise in March 2021.

Gain on Debt Extinguishment

The Company recognized a gain on the extinguishment of debt of $568,505 for the nine months ended September 30, 2021 related to the forgiveness of our loan under the Small Business Administration’s Paycheck Protection Program.

Liquidity and Capital Resources

We have incurred net losses since our inception. For the three months ended September 30, 2022 and 2021, we incurred net losses of $7,628,054 and $5,057,581, respectively. For the nine months ended September 30, 2022 and 2021, we incurred net losses of $23,013,992 and $9,194,757, respectively. As of September 30, 2022, we had an accumulated deficit of $97,065,906.

We expect to incur additional losses in the near future, and we expect our expenses to increase substantially in connection with our ongoing activities, particularly as we continue to develop our bioengineered organs, as we conduct clinical trials and other studies for our bioengineered organs, seek regulatory clearances or approvals for Miroliver and Mirokidney, continue preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and to invest in our infrastructure to support our future manufacturing and other activities. We expect to incur additional costs associated with operating as a public company in the United States. 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

To date, we have primarily financed our operations through equity and debt financings, as well as research grants and our IPO. We believe that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements through December 2023. As of September 30, 2022, we had cash and cash equivalents of $5,537,818 and short-term investments of $26,003,087. 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.

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 and debt financings. 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

23

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 potential worsening global economic conditions. 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 2012, we signed a promissory note with the University for $405,559. The promissory note bears interest at 3% per annum, compounded monthly. The note is scheduled to mature on December 31, 2022 and is unsecured. We are required to make monthly principal and interest payments of $7,737 until the note is paid in full. In connection with the promissory note, we issued the University warrants to purchase 80,000 shares of our common stock at an exercise price of $1.69. As of September 30, 2022 and December 31, 2021, the principal outstanding on this loan was $15,417 and $83,849, respectively.

In May 2015, we entered into a loan agreement with the Minnesota Department of Employment & Economic Development under which we borrowed $250,000. The loan was unsecured and did not bear interest. The loan was due in a lump sum payment on April 1, 2022. As of September 30, 2022 and December 31, 2021, the balance outstanding on this loan was $0 and $250,000.

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 September 30, 2022 and December 31, 2021, the principal outstanding on this loan was $385,997.

Initial Public Offering

In June 2021, we completed our IPO through which we issued and sold 5,520,000 shares of common stock at $9.00 per share. In connection with the IPO, we raised $44,528,060, after deducting the underwriting discount and offering expenses payable by us.

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 a Registration Statement on Form S-3, filed with the SEC on July 1, 2022 and declared effective on July 11, 2022 (the “Registration Statement”). We did not issue any shares under the Equity Distribution Agreement in the nine months ended September 30, 2022.

Registration Statement

We filed the Registration Statement with the SEC on July 1, 2022 which was declared effective on July 11, 2022. 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/or warrants to purchase any of such securities, having an aggregate initial offering price of $200.0 million.

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:

DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

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 the Mayo Clinic, Mount Sinai Health System and the Texas Heart Institute, and has received strategic investments from Baxter International, Inc., CareDx, Inc. 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 and the rules of the United States (“U.S.”) Securities and Exchange Commission (“SEC”) 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, 2021. 

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 2022 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.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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.

Investments

The Company 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.

Deferred Offering Costs

Deferred offering costs are expenses directly related to the Shelf Registration Statement on Form S-3 filed with the SEC on July 1, 2022 and declared effective on July 11, 2022 (the “Shelf Registration”). These costs consist of legal, accounting, printing and filing fees that the Company has capitalized, including fees incurred by the independent registered public accounting firm directly related to the Shelf Registration. Deferred costs associated with the Shelf Registration will be reclassified to additional paid-in capital on a pro-rata basis when the Company completes offerings under the Shelf Registration. Any remaining deferred offering costs will be charged to the statement of operations at the earlier of when it becomes probable that the offering will not result in the receipt of proceeds from the issuance of securities or at the end of the three-year life of the Shelf Registration.

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 Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“ASC 842”), which requires lessees to recognize the assets and liabilities that arise from leases on the balance sheet. The standard also requires expanded disclosures to help financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. The Company adopted the new standard effective January 1, 2022 using the modified retrospective approach.

The Company determines if an arrangement is a lease at inception. Operating leases are included in right of use assets and lease liabilities on the condensed balance sheets. The right of use assets and lease liabilities are recognized as the present value of the future minimum lease payments over the lease term at commencement date. The right of use asset is also adjusted for any lease payments made and excludes lease incentives and initial direct costs incurred. As most leases do not provide an implicit rate, and the Company does not have a readily available incremental borrowing rate, the Company uses the interest rate available for the lowest-grade debt in the marketplace based on the information available at commencement date in determining the present value of future payments.

The standard provides a number of optional practical expedients in transition. The Company elected to exercise the package of practical expedients, which, among other things, allows the Company to carryforward the determining lease classification and lease term.

As a result of adopting the new standard, the Company recognized right of use assets of $1,882,696 and lease liabilities of $2,020,839 as of January 1, 2022. Certain amounts in the prior year financial statements have been reclassified for comparative purposes to conform to the presentation for the three and nine months ended September 30, 2022. Specifically, prior to the adoption of ASC 842, the Company presented capital leases together with long-term debt on the balance sheets. Financing leases (previously capital leases) is now presented separately on the balance sheets. In addition, prior to the adoption of ASC 842, the Company presented the non-cash change in deferred rent as deferred rent within the operating section of the statement of cash flows. This balance is now presented on the operating lease right of use asset line within the operating section of the statement of cash flows. The adoption of this standard did not have a material impact on income or cash flows. See Note 11 for further details.

Accounting Pronouncements Not Yet Adopted

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. There are various transition methods available upon adoption. As an emerging growth company, the Company is permitted to defer adoption until the private company adoption date of annual periods started after December 15, 2022. The Company is currently evaluating the impact of adoption on its financial statements.

NOTE 2 — 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 on September 30, 2022 had contractual maturities of less than one year.

The amortized cost and estimated fair values of the Company’s investments as of September 30, 2022 are as follows:

	Amortized		Unrealized		Unrealized		Fair
	Cost		Holding Gains		Holding Losses		Value
Short-term:

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT

NOTE 6 — 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.

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.

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 and the rules of the United States (“U.S.”) Securities and Exchange Commission (“SEC”) 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, 2021. 

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 2022 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.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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.

Investments

Investments

The Company 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.

Deferred Offering Costs

Deferred Offering Costs

Deferred offering costs are expenses directly related to the Shelf Registration Statement on Form S-3 filed with the SEC on July 1, 2022 and declared effective on July 11, 2022 (the “Shelf Registration”). These costs consist of legal, accounting, printing and filing fees that the Company has capitalized, including fees incurred by the independent registered public accounting firm directly related to the Shelf Registration. Deferred costs associated with the Shelf Registration will be reclassified to additional paid-in capital on a pro-rata basis when the Company completes offerings under the Shelf Registration. Any remaining deferred offering costs will be charged to the statement of operations at the earlier of when it becomes probable that the offering will not result in the receipt of proceeds from the issuance of securities or at the end of the three-year life of the Shelf Registration.

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 and Accounting Pronouncements Not Yet Adopted

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“ASC 842”), which requires lessees to recognize the assets and liabilities that arise from leases on the balance sheet. The standard also requires expanded disclosures to help financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. The Company adopted the new standard effective January 1, 2022 using the modified retrospective approach.

The Company determines if an arrangement is a lease at inception. Operating leases are included in right of use assets and lease liabilities on the condensed balance sheets. The right of use assets and lease liabilities are recognized as the present value of the future minimum lease payments over the lease term at commencement date. The right of use asset is also adjusted for any lease payments made and excludes lease incentives and initial direct costs incurred. As most leases do not provide an implicit rate, and the Company does not have a readily available incremental borrowing rate, the Company uses the interest rate available for the lowest-grade debt in the marketplace based on the information available at commencement date in determining the present value of future payments.

The standard provides a number of optional practical expedients in transition. The Company elected to exercise the package of practical expedients, which, among other things, allows the Company to carryforward the determining lease classification and lease term.

As a result of adopting the new standard, the Company recognized right of use assets of $1,882,696 and lease liabilities of $2,020,839 as of January 1, 2022. Certain amounts in the prior year financial statements have been reclassified for comparative purposes to conform to the presentation for the three and nine months ended September 30, 2022. Specifically, prior to the adoption of ASC 842, the Company presented capital leases together with long-term debt on the balance sheets. Financing leases (previously capital leases) is now presented separately on the balance sheets. In addition, prior to the adoption of ASC 842, the Company presented the non-cash change in deferred rent as deferred rent within the operating section of the statement of cash flows. This balance is now presented on the operating lease right of use asset line within the operating section of the statement of cash flows. The adoption of this standard did not have a material impact on income or cash flows. See Note 11 for further details.

Accounting Pronouncements Not Yet Adopted

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. There are various transition methods available upon adoption. As an emerging growth company, the Company is permitted to defer adoption until the private company adoption date of annual periods started after December 15, 2022. The Company is currently evaluating the impact of adoption on its financial statements.
