Notes to Condensed Consolidated Financial Statements

(Unaudited)

1.         Description of Business

Overview

ThermoGenesis Holdings, Inc. (“ThermoGenesis Holdings,” the “Company,” “we,” “our,” “us”) develops and commercializes a range of automated technologies for cell-banking, cell-processing, and cell-based therapeutics. Since the 1990’s, ThermoGenesis Holdings has been a pioneer in, and a leading provider of automated systems that isolate, purify and cryogenically store units of hematopoietic stem and progenitor cells for the cord blood banking industry. The Company was founded in 1986 and is incorporated in the State of Delaware and headquartered in Rancho Cordova, CA. Our common stock is traded on the Nasdaq Capital Market under the ticker symbol “THMO”.

Medical Device Products for Automated Cell Processing

The Company provides the AutoXpress® and BioArchive® platforms for automated clinical bio-banking, PXP® platform for point-of-care cell-based therapies and the CAR-TXpress™ platform for large scale cell manufacturing services. All product lines are reporting as a single reporting segment in the financial statements.

CDMO Business

The Company is expanding its business to include contract development and manufacturing services for cell and cell-based gene therapies. The Company is in the process of building out the capabilities to become a world-class Contract Development and Manufacturing Organization (“CDMO”) for cell and cell-based gene therapies. The Company is rolling out a new facility in the Sacramento metro area, containing a total of 12, class-7, ReadyStart cGMP Suites available for lease by early-stage life science and cell gene therapy companies. The ReadyStart Suites are located in a 35,500+ square foot cGMP facility that will meet the highest scientific, quality, and regulatory requirements. We expect the CDMO facility to be completed in 2023.

Reverse Stock Split

On December 22, 2022, we effected a one (1) for forty-five (45) reverse stock split of our issued and outstanding common stock. All historical share amounts disclosed in this quarterly report on Form 10-Q have been retroactively restated to reflect the reverse split and subsequent share exchange. No fractional shares were issued as a result of the reverse stock split, as fractional shares of common stock were rounded up to the nearest whole share.

2.         Going Concern

The Company has incurred historical losses from operations and expects to continue to incur operating losses in the near future. The Company may need to raise additional capital to grow its business, fund operating expenses and make interest payments. The Company’s ability to fund its liquidity needs is subject to various risks, many of which are beyond its control. The Company may seek additional funding through debt borrowings, sales of debt or equity securities or strategic partnerships. The Company cannot guarantee that such funding will be available on a timely basis, in needed quantities or on terms favorable to the Company, if at all. These factors and other indicators raise substantial doubt about the Company’s ability to continue as a going concern within one year from the filing date of this report.

5

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should the Company be unable to continue as a going concern.

3.         Summary of Significant Accounting Polices

There have been no material changes in the Company’s significant accounting policies to those disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such Securities and Exchange Commission (“SEC”) rules and regulations and accounting principles applicable for interim periods. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of the results for the periods presented have been included. Events subsequent to the balance sheet date have been evaluated for inclusion in the accompanying condensed consolidated financial statements through the date of issuance.

Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the Company’s fiscal year ending December 31, 2023. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in ThermoGenesis Holdings’ Annual Report on Form 10-K for the year ended December 31, 2022.

Principles of Consolidation

The consolidated financial statements include the accounts of ThermoGenesis Holdings and its wholly-owned subsidiaries, ThermoGenesis Corp. and TotipotentRX Cell Therapy, Pvt. Ltd and ThermoGenesis Corp’s majority-owned subsidiary, CARTXpress Bio, Inc (“CARTXpress Bio”). All significant intercompany accounts and transactions have been eliminated upon consolidation.

The 20% ownership interest of CARTXpress Bio that is not owned by ThermoGenesis Holdings is accounted for as a non-controlling interest as the Company has an 80% ownership interest in CARTXpress Bio. Earnings or losses attributable to other stockholders of a consolidated affiliated company are classified separately as "non-controlling interest" in the Company's consolidated statements of operations. Net loss attributable to non-controlling interests reflects only its share of the after-tax earnings or losses of an affiliated company. The Company's condensed consolidated balance sheets reflect non-controlling interests within the equity section.

Recently Adopted Accounting Standards

On January 1, 2022, we adopted Accounting Standards Update (“ASU”) 2020-06 “Debt-Debt with Conversion and Other Options (“Subtopic 470-20”) and Derivatives and Hedging-Contracts in Entity’s Own Equity (“Subtopic 815-40”): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” using the modified retrospective method. ASU 2020-06 provides guidance on how to account for contracts on an entity’s own equity. This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. Specifically, the ASU eliminated the need for the Company to assess whether a contract on the entity’s own equity (1) permits settlement in unregistered shares, (2) whether counterparty rights rank higher than shareholder’s rights, and (3) whether collateral is required. The Company recognized a cumulative effect of $9,739,000 of initially applying the ASU as an adjustment to the January 1, 2022 opening balance of accumulated deficit. Due to the recombination of the equity conversion component of our convertible debt outstanding, the 2022 opening balance of additional paid in capital was reduced by $10,681,000 and the debt discounts of the convertible promissory notes were reduced $942,000.

6

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (“Topic 326”). The ASU introduced a new accounting model, the Current Expected Credit Losses model (“CECL”), which requires earlier recognition of credit losses and additional disclosures related to credit risk. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses at the time the financial asset is originated or acquired. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2022, including interim reporting periods within those annual reporting periods. The Company adopted the standard effective January 1, 2023. Based on the composition of the Company’s trade receivables and unbilled revenue, and expected future losses, the adoption of ASU 2016-13 did not have a material impact on its condensed consolidated financial statements.

4.         Related Party Transactions

Convertible Promissory Note and Revolving Credit Agreement

In March 2017, ThermoGenesis Holdings entered into a Credit Agreement with Boyalife Group (USA), Inc. (the “Lender”), which is owned and controlled by the Company’s Chief Executive Officer and Chairman of our Board of Directors. The Credit Agreement, as amended, grants the Company the right to borrow up to $10,000,000 (the “Loan”) at any time prior to the maturity date. On March 6, 2023, the Company entered into an Amendment No. 2 (the “Amendment to the Note”) to its Second Amended and Restated Convertible Promissory Note with Boyalife Group Inc. (the “Note”), and an Amendment No. 3 to its First Amended and Restated Revolving Credit Agreement with Boyalife Group Inc. The Amendment to the Note amended and extended the maturity date of the Note from March 6, 2023 to December 31, 2023 (the “Maturity Date”) and added to the principal balance of the Note all accrued and unpaid interest at the time of the extension, resulting in an outstanding principal balance of $7,278,000 as of March 6, 2023.

The Company performed a debt extinguishment vs. modification analysis on the Amendment to the Note and determined that the amendment would be considered an extinguishment, due to an increase of more than 10% to the value of the embedded conversion option. However, no gain or loss was recorded in the condensed consolidated statements of operations and comprehensive loss at the time of the Amendment as it was determined that the fair value of the Amendment to the Note and accrued interest was $7,278,000 both before and after the extension.

The Credit Agreement and the Note, as amended provide that the principal and all accrued and unpaid interest under the Loan will be due and payable on the Maturity Date, with payments of interest-only due on the last day of each calendar year. The Loan bears interest at 22% per annum, simple interest. The Company has five business days after the Lender demands payment to pay the interest due before the Loan is considered in default. The Loan can be prepaid in whole or in part by the Company at any time without penalty.

The following summarizes the Note:

	Maturity Date	Stated Interest Rate			Conversion Price		Face Value		Debt Discount			Carrying Value
June 30, 2023	12/31/23		22	%	$	2.65	$	7,278,000	$	(521,000	)	$	6,757,000
December 31, 2022	12/31/23		22	%	$	6.30	$	7,000,000	$	(1,223,000	)	$	5,777,000

The Note includes a down-round anti-dilution provision that lowers its conversion price if the Company sells shares of common stock or issues convertible debt at a lower price per share. Through June 30, 2023, the down-round provision was triggered as noted below:

In January 2023, when the conversion price of the Note was at $6.30 per share, the Company amended a previously outstanding convertible note, resulting in a triggering event lowering the conversion price of the Note to $2.87. The Company determined that it created an incremental value of $2,350,000 which was treated as a discount to the carrying amount of the Note and amortized over its remaining term.

In March 2023, the Company sold shares of common stock and warrants at $2.65 per share, resulting in a down round triggering event lowering the conversion price of the Note to that value. The triggering event created an incremental value of $810,000 which was treated as a discount to the carrying amount of the Note and will be amortized over its remaining term.

A Black-Scholes pricing model was utilized to determine the change in the before and after incremental value of the conversion option at each triggering event, with the following inputs:

	January 2023			March 2023
Conversion price before	$	6.30		$	2.87
Conversion price after	$	2.87		$	2.65
Term (years)		0.09			0.78
Volatility		167	%		168.9	%
Dividend rate		0	%		0	%
Risk free rate		4.46	%		4.20	%

For the three and six months ended June 30, 2023, the Company amortized $258,000 and $3,862,000 of debt discount related to triggering events, compared to $742,000 and $955,000 for the three and six months ended June 30, 2022. In addition to the amortization, the Company also recorded interest expense of $405,000 and $794,000 for the three and six months ended June 30, 2023, compared to $552,000 and $1,102,000 for the three and six months ended June 30, 2022, respectively. The interest payable balance as of June 30, 2023 and December 31, 2022 was $516,000 and $1,492,000, respectively.

Boyalife Genomics

On March 24, 2022, the Company entered into a License and Technology Access Agreement with Boyalife Genomics Tianjin Ltd. (“Boyalife Genomics”), a China-based CDMO and an affiliate of ThermoGenesis’ Chairman and Chief Executive Officer, Chris Xu, Ph.D. The agreement provides for a U.S. license to certain existing and future know-how and other intellectual property relating to cell manufacturing and related processes.

Z3 Investment

On March 24, 2022, the Company entered into a five-year Lease Agreement with Z3 Investment LLC, an affiliate owned by the Company’s CEO and Chairman of the Board and the Company’s Chief Operating Officer who is also a Board Member, beginning April 1, 2022, for approximately 35,000 square feet of laboratory and office space in Rancho Cordova, California. Under the terms of the agreement, monthly rent is $104,000 per month (with a 4% annual increase). Additionally, the Company will pay all operating expenses as they become due estimated to be approximately $10,000 per month and will be expensed in the period incurred. The Company has the option to renew the lease for up to ten years after the commencement of the initial five-year term.

Operating Lease

Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, we use the Company’s cost of capital based on existing debt instruments. We recognize the expense for this lease on a straight-line basis over the lease term.

The following summarizes the Company’s operating lease:

	June 30, 2023			December 31, 2022
Right-of-use operating lease assets – related party, net	$	3,331,000		$	3,550,000
Current lease liability (included in other current liabilities)		509,000			433,000
Non-current lease liability – related party		3,220,000			3,495,000
Weighted average remaining lease term		4.3			4.8
Discount rate		22	%		22	%

Maturities of lease liabilities by year for our operating lease are as follows:

2023 (Remaining)	$	634,000
2024		1,307,000
2025		1,359,000
2026		1,428,000
Thereafter		1,133,000
Total lease payments	$	5,861,000
Less: imputed interest		(2,132,000	)
Present value of operating lease liabilities	$	3,729,000

Statement of Cash Flows

Cash paid for amounts included in the measurement of operating lease liabilities was $622,000 and $138,000 for the six months ended June 30, 2023 and 2022, respectively.

6.         Convertible Promissory Note

July 2019 Note

On July 23, 2019, the Company entered into a private placement with Orbrex (USA) Co. Limited (“Orbrex”), pursuant to which the Company issued and sold to Orbrex an unsecured convertible promissory note in the original principal amount of $1,000,000 (the “July 2019 Note”). The July 2019 Note bears interest at a rate of twenty-four percent (24%) per annum and is payable quarterly in arrears. On January 31, 2023, the Company entered into Amendment No. 3 to the July 2019 Note. The amendment extended the maturity date from January 31, 2023 to July 31, 2023 and changed the fixed conversion price to $2.87 per share.

The Company performed a debt extinguishment vs. modification analysis on the amendment to the July 2019 Note and determined that the extension would be considered an extinguishment, due to an increase of more than 10% to the value of the embedded conversion option. The Company determined that the fair value of the July 2019 Note after the amendment was $1,239,000 representing a $239,000 increase in its fair value. The increase will be recorded as a premium to the July 2019 Note and amortized over the remaining term.

Subsequent to June 30, 2023, the Company entered into an Amendment No. 4 to the July 2019 Note with Orbrex (USA) Co. Limited (the “July 2019 Note Amendment”). The July 2019 Note Amendment amends the July 2019 Note to extend the maturity date of the July 2019 Note from July 31, 2023 to January 31, 2024. The Note Amendment also changed the fixed conversion price to $1.07 per share, provided that in the event that the Company issues shares, options, warrants, or convertible securities, subject to certain exceptions, at an effective price per common share lower than $1.07, then the conversion price will be adjusted to such lower issuance price.

The following summarizes the July 2019 Note:

	Maturity Date	Stated Interest Rate			Conversion Price		Face Value		Debt Discount/ Premium			Carrying Value
June 30, 2023	7/31/2023		24	%	$	2.65	$	397,000	$	7,000		$	404,000
December 31, 2022	7/31/2023		24	%	$	6.30	$	1,000,000	$	(38,000	)	$	962,000

The Note includes a down-round anti-dilution provision that lowers its conversion price if the Company sells shares of common stock or issues convertible debt at a lower price per share. In 2023, the anti-dilution provision was triggered, as noted below:

In March 2023, the Company sold shares of common stock at $2.65 per share, resulting in a down round triggering event lowering the conversion price of the Note to that value. The triggering event created an incremental value of $43,000 which was treated as a discount to the carrying amount of the July 2019 Note and will be amortized over its remaining term.

10

A Black-Scholes pricing model was utilized to determine the change in the before and after incremental value of the conversion option at each triggering event, with the following inputs:

	March 2023
Conversion price before	$	2.87
Conversion price after	$	2.65
Term (years)		0.36
Volatility		182	%
Dividend rate		0	%
Risk free rate		4.20	%

The Company recorded amortization expense for the July 2019 Note of $(18,000) and $(190,000) for the three and six months ended June 30, 2023, respectively. In addition to the amortization, the Company also recorded interest expense related to the July 2019 Note of $24,000 and $66,000 for the three and six months ended June 30, 2023, compared to $60,000 and $120,000 for the three and six months ended June 30, 2022, respectively.

7.         Stockholders’ Equity

Common Stock

On March 15, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an accredited investor (the “Investor”) pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Offering”) (i) 125,000 shares of its common stock, $0.001 par value (the “Common Shares”), (ii) 946,429 pre-funded warrants to purchase Common Shares at a purchase price of $2.80, and (iii) common stock warrants to purchase up to an aggregate 1,071,429 Common Shares were issued (the “Underlying Shares”). The common stock warrants have an exercise price of $2.65 per share and are exercisable immediately upon issuance and expire five and one-half years following the issuance. The Offering resulted in a total net proceeds of approximately $2.6 million, excluding legal and other transaction fees of $360,000. The Offering closed on March 20, 2023. All 946,429 pre-funded warrants were exercised in the quarter ended June 30, 2023.

In connection with the Offering, the Company entered into a Warrant Amendment Agreement (the "Warrant Amendment Agreement”), dated March 15, 2023, with the Investor, whereby the Company agreed to amend existing warrants, held by the Investor, to purchase up to an aggregate of 158,731 shares of common stock that were previously issued in October 2022. These warrants had an exercise price of $6.30 per share and pursuant to the Warrant Amendment Agreement have been amended to reduce the exercise price to $2.65 per share effective upon the closing of the Offering. During the six months ended June 30, 2023, 158,731 common warrants were exercised. The Company received approximately $421,000 from the exercises of the warrants.

11

The warrant repricing resulted in an immediate and incremental increase of approximately $50,000 in the estimated fair value of the common warrants issued in the Company’s October 2022 public offering. The common warrants were valued on the date of the warrant repricing using the Black-Scholes option pricing model based on the following assumptions:

	March 2023
Conversion price before	$	6.30
Conversion price after	$	2.65
Term (years)		4.9
Volatility		123	%
Dividend rate		0	%
Risk free rate		4.20	%

On February 3, 2022, the Company entered into Amendment No. 2 to the At the Market Offering Agreement (the “Offering Agreement”) with H.C. Wainwright & Co., LLC to further increase the maximum aggregate offering price of shares of Common Stock that may be offered and sold from time to time under the Offering Agreement from $15,280,000 to $19,555,000, which enables the Company to sell an additional $4,275,000 of shares after taking into account prior sales under the Offering Agreement (the “Additional Shares”). In March 2022, the total offering price was updated to $18,573,000 based on the shares that were currently available on Company’s existing Form S-3. The terms and conditions of the Offering Agreement otherwise remain unchanged. For the six months ended June 30, 2022, the Company sold a total of 20,407 shares of common stock under the Offering Agreement for aggregate gross proceeds of $681,000 at an average selling price of $33.30 per share, resulting in net proceeds of approximately $594,000 after deducting commissions and other transaction costs of approximately $87,000.

12

Net Loss Per Share

Net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding plus the pre-funded warrants. For the purpose of calculating basic net loss per share, the additional shares of common stock that are issuable upon exercise of the pre-funded warrants have been included since the shares are issuable for a negligible consideration and have no vesting or other contingencies associated with them. As of June 30, 2023, all pre-funded warrants previously issued have been exercised and none are outstanding. The calculation of the basic and diluted earnings per share is the same for all periods presented, as the effect of the potential common stock equivalents noted below is anti-dilutive due to the Company’s net loss position for all periods presented. Anti-dilutive securities consisted of the following at June 30:

	2023		2022
Common stock equivalents of convertible promissory notes and accrued interest		3,108,264		649,667
Warrants		1,239,547		14,518
Stock options		6,400		6,526
Total		4,354,211		670,711

Warrants

A summary of warrant activity for the six months ended June 30, 2023 is as follows:

	Number of Shares			Weighted-Average Exercise Price Per Share		Weighted- Average Remaining Contract Term
Balance at December 31, 2022		340,689		$	19.40		1.90

Expansion of Business – Contract Development and Manufacturing Services for Cell and Cell-Based Gene Therapies

The Company expanded its business to include contract development and manufacturing services for cell and cell-based gene therapies. The Company is in the process of building out the capabilities to become a world-class Contract Development and Manufacturing Organization (“CDMO”) for cell and cell-based gene therapies. The Company is rolling out a new facility in the Sacramento metro area, containing a total of 12, class-7, ReadyStart cGMP Suites available for lease by early-stage life science and cell gene therapy companies. The ReadyStart Suites are located in a 35,500+ square foot cGMP facility that will meet the highest scientific, quality, and regulatory requirements. We intend to leverage our existing technology and combine it with the in-licensed technologies to develop a proprietary manufacturing platform for cell manufacturing activities.

The Company plans to develop and operate its planned CDMO business through a newly formed division named TG Biosynthesis^TM. It is anticipated that TG Biosynthesis will provide high-quality development and manufacturing capabilities, cell and tissue processing development, quality systems, regulatory compliance, and other cell manufacturing solutions for clients with therapeutic candidates in various stages of development.

We expect the CDMO facility to be completed in 2023. The successful development and launch of TG Biosynthesis will require us to acquire various equipment for the planned operations, hire certain personnel needed to launch the operation, and timely complete the build-out of our leased Sacramento facility. There is no assurance that we will be able to successfully obtain such additional capital resources, as such capital may not be available on reasonable terms, or available at all. We will need to hire, train, and retain additional employees who have experience in the cell manufacturing field in order for our CDMO business to be successful.

Results of Operations

Three Months Ended June 30, 2023 as Compared to the Three Months Ended June 30, 2022

Net Revenues

Net revenues decreased by $756,000 or 25%, from $3,029,000 to $2,273,000 for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022. The decrease in revenue was driven by lower AXP disposable sales to the Company’s distributor in China, which were offset by higher domestic AXP disposables sales and BioArchive device revenue for the quarter ended June 30, 2023.

The following table summarizes revenue by product line:

	June 30, 2023		June 30, 2022
AXP	$	1,316,000	$	1,963,000
BioArchive		789,000		643,000
CAR-TXpress		130,000		292,000
Manual Disposables		14,000		102,000
Other		24,000		29,000
Total	$	2,273,000	$	3,029,000

Gross Profit

The Company’s gross profit decreased by $470,000 to $469,000 or 21% of net revenues for the three months ended June 30, 2023, compared to $939,000 or 31% for three months ended June 30, 2022. The primary drivers of the decrease were the reduced revenue and lower absorption driven by excess manufacturing capacity in the second quarter of 2023.

Selling, General and Administrative

Sales, general and administrative expenses for the three months ended June 30, 2023 were $1,816,000 compared to $1,989,000 for the three months ended June 30, 2022, a decrease of $173,000 or 9%. The decrease was driven by lower employee benefit expenses of approximately $120,000 and decreased legal fees of approximately $60,000.

Research and Development Expenses

Research and development expenses were $383,000 for the three months ended June 30, 2023 as compared to $392,000 for the three months ended June 30, 2022, a decrease of $9,000 or 2%.

18

Interest Expense

Interest expense for the three months ended June 30, 2023 was $668,000 compared to $1,359,000, for the three months ended June 30, 2022, a decrease of $691,000. The decrease was driven by approximately $500,000 less in amortization expenses resulting from triggering events and approximately $175,000 less in interest expense related to the Note and July 2019 Note in the three months ended June 30, 2023 as compared to the same period in 2022.

Six Months Ended June 30, 2023 as Compared to the Six Months Ended June 30, 2022

Net Revenues

Net revenues decreased by $847,000 or 15%, from $5,692,000 to $4,845,000 for the six months ended June 30, 2023 as compared to the six months ended June 30, 2022. The decrease in revenue was driven by lower AXP disposable sales to the Company’s distributor in China and lower CAR-TXpress sales which were offset by BioArchive device revenue for the six months ended June 30, 2023.

	Six Months Ended June 30,
	2023		2022
AXP	$	2,855,000	$	3,730,000
BioArchive		1,446,000		1,096,000
CAR-TXpress		276,000		604,000
Manual Disposables		221,000		207,000
Other		47,000		55,000
Total	$	4,845,000	$	5,692,000

Gross Profit

The Company’s gross profit was $1,574,000 or 32% of net revenues for the six months ended June 30, 2023, compared to $1,879,000 or 33% of net revenues for the six months ended June 30, 2022, a decrease of $305,000. The primary drivers of the decrease were lower sales in the six months ended June 30, 2023.

Selling, General and Administrative

Sales, general and administrative expenses for the six months ended June 30, 2023 were $3,660,000 compared to $3,682,000 for the six months ended June 30, 2022, a decrease of $22,000 or 1%. The variance was driven by increased operating expenses for the Company’s CDMO facility of approximately $350,000 and offset by lower employee benefit expenses.

Research and Development Expenses

Research and development expenses were $689,000 for the six months ended June 30, 2023, compared to $847,000 for the six months ended June 30, 2022, a decrease of $158,000 or 19%.  The decrease was driven by lower personnel expenses of approximately $50,000 and lower project expenses of approximately $100,000. 

Interest Expense

Interest expense increased to $4,571,000 for the six months ended June 30, 2023 as compared to $2,182,000 for the six months ended June 30, 2022, an increase of $2,389,000.  The increase was driven by approximately $2,900,000 in additional amortization expenses related to triggering events that occurred in the six months ended June 30, 2023 for Company’s convertible notes payable, which were offset by approximately $400,000 less in interest expense for the Note with Boyalife Group, Inc. and the July 2019 Note.

19

Liquidity and Capital Resources

The Company had cash and cash equivalents of $4,450,000 and $4,177,000 and working capital deficit of $2,534,000 and $625,000 at June 30, 2023 and December 31, 2022, respectively. We have primarily financed cash shortfalls from operations through private and public placement of equity and debt securities.

On March 15, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an accredited investor (the “Investor”) pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Offering”) (i) 125,000 shares of its common stock, $0.001 par value (the “Common Shares”), (ii) 946,429 pre-funded warrants to purchase Common Shares at a purchase price of $2.80, and (iii) common stock warrants to purchase up to an aggregate of 1,071,429 Common Shares. The warrants have an exercise price of $2.65 per share and are exercisable immediately upon issuance and expire five and one-half years following the issuance for a total net proceeds of approximately $2.6 million, excluding legal and transaction fees. The Offering closed on March 20, 2023. As of June 30, 2023, all pre-funded warrants were exercised.

Subsequent to June 30, 2023, on July 31, 2023 the Company entered into an Amendment No. 4 to the July 2019 Note with Orbrex (USA) Co. Limited (the "July 2019 Note Amendment”). The July 2019 Note Amendment amends the July 2019 Note to extend the maturity date of the July 2019 Note from July 31, 2023 to January 31, 2024. The July 2019 Note Amendment also changed the fixed conversion price under the July 2019 Note to $1.07 per share, provided that in the event that the Company issues shares, options, warrants, or convertible securities, subject to certain exceptions, at an effective price per common share lower than $1.07, then the conversion price will be adjusted to such lower issuance price.  As a result of the July 2019 Note Amendment, the conversion price of the Note with Boyalife Group was likewise reduced to $1.07 under the down-round conversion price adjustment provisions of such Note.

The Company has incurred historical losses from operations and expects to continue to incur operating losses in the near future. We anticipate opening our new CDMO facility in 2023 and increasing cash from operations. The Company will likely need to raise additional capital to grow its business, fund operating expenses and make interest payments. The Company’s ability to fund its liquidity needs is subject to various risks, many of which are beyond its control. The Company may seek additional funding through debt borrowings, sales of debt or equity securities or strategic partnerships. The Company cannot guarantee that such funding will be available on a timely basis, in needed quantities or on terms favorable to the Company, if at all. These factors and other indicators raise substantial doubt about the Company’s ability to continue as a going concern within one year from the filing date of this report.

We manage the concentration of credit risk with our customers and distributors through a variety of methods including pre-shipment deposits, credit reference checks and credit limits. Although management believes that our customers and distributors are sound and creditworthy, a severe adverse impact on their business operations could have a corresponding material effect on their ability to pay timely and therefore on our net revenues, cash flows and financial condition.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

ThermoGenesis Holdings is a smaller reporting company as defined by Rule 12b-2 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”) and is not required to provide information under this item.

ITEM 4. Controls and Procedures

The Company carried out an evaluation, under the supervision, and with the participation of management, including both the Company’s Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined by Exchange Act Rule 13a-15(e) or 15d-15(e)) as of June 30, 2023. Disclosure controls and procedures cover controls and other procedures that are designed to ensure that information required to be disclosed by the Company in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have both concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2023.

20

There were no changes in the Company’s internal controls over financial reporting that occurred during the three months ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting. Management believes that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within any company, have been detected.

PART II - OTHER INFORMATION

ITEM 1.         Legal Proceedings

In the normal course of operations, we may have disagreements or disputes with distributors, vendors or employees. Such potential disputes are seen by management as a normal part of business and while the outcome of such disagreements and disputes cannot be predicted with certainty, we do not believe that any pending legal proceedings are material. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

ITEM 1A.         Risk Factors

There have been no material changes to the risk factors relating to the Company set forth in, “Item IA. Risk Factors” of its Annual Report on Form 10-K for the year ended December 31, 2022.

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

None.

Business Description and Basis of Presentation [Text Block]

1.         Description of Business

Overview

ThermoGenesis Holdings, Inc. (“ThermoGenesis Holdings,” the “Company,” “we,” “our,” “us”) develops and commercializes a range of automated technologies for cell-banking, cell-processing, and cell-based therapeutics. Since the 1990’s, ThermoGenesis Holdings has been a pioneer in, and a leading provider of automated systems that isolate, purify and cryogenically store units of hematopoietic stem and progenitor cells for the cord blood banking industry. The Company was founded in 1986 and is incorporated in the State of Delaware and headquartered in Rancho Cordova, CA. Our common stock is traded on the Nasdaq Capital Market under the ticker symbol “THMO”.

Medical Device Products for Automated Cell Processing

The Company provides the AutoXpress® and BioArchive® platforms for automated clinical bio-banking, PXP® platform for point-of-care cell-based therapies and the CAR-TXpress™ platform for large scale cell manufacturing services. All product lines are reporting as a single reporting segment in the financial statements.

CDMO Business

The Company is expanding its business to include contract development and manufacturing services for cell and cell-based gene therapies. The Company is in the process of building out the capabilities to become a world-class Contract Development and Manufacturing Organization (“CDMO”) for cell and cell-based gene therapies. The Company is rolling out a new facility in the Sacramento metro area, containing a total of 12, class-7, ReadyStart cGMP Suites available for lease by early-stage life science and cell gene therapy companies. The ReadyStart Suites are located in a 35,500+ square foot cGMP facility that will meet the highest scientific, quality, and regulatory requirements. We expect the CDMO facility to be completed in 2023.

Reverse Stock Split

On December 22, 2022, we effected a one (1) for forty-five (45) reverse stock split of our issued and outstanding common stock. All historical share amounts disclosed in this quarterly report on Form 10-Q have been retroactively restated to reflect the reverse split and subsequent share exchange. No fractional shares were issued as a result of the reverse stock split, as fractional shares of common stock were rounded up to the nearest whole share.

Substantial Doubt about Going Concern [Text Block]

2.         Going Concern

The Company has incurred historical losses from operations and expects to continue to incur operating losses in the near future. The Company may need to raise additional capital to grow its business, fund operating expenses and make interest payments. The Company’s ability to fund its liquidity needs is subject to various risks, many of which are beyond its control. The Company may seek additional funding through debt borrowings, sales of debt or equity securities or strategic partnerships. The Company cannot guarantee that such funding will be available on a timely basis, in needed quantities or on terms favorable to the Company, if at all. These factors and other indicators raise substantial doubt about the Company’s ability to continue as a going concern within one year from the filing date of this report.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should the Company be unable to continue as a going concern.

Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]

3.         Summary of Significant Accounting Polices

There have been no material changes in the Company’s significant accounting policies to those disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such Securities and Exchange Commission (“SEC”) rules and regulations and accounting principles applicable for interim periods. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of the results for the periods presented have been included. Events subsequent to the balance sheet date have been evaluated for inclusion in the accompanying condensed consolidated financial statements through the date of issuance.

Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the Company’s fiscal year ending December 31, 2023. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in ThermoGenesis Holdings’ Annual Report on Form 10-K for the year ended December 31, 2022.

Principles of Consolidation

The consolidated financial statements include the accounts of ThermoGenesis Holdings and its wholly-owned subsidiaries, ThermoGenesis Corp. and TotipotentRX Cell Therapy, Pvt. Ltd and ThermoGenesis Corp’s majority-owned subsidiary, CARTXpress Bio, Inc (“CARTXpress Bio”). All significant intercompany accounts and transactions have been eliminated upon consolidation.

The 20% ownership interest of CARTXpress Bio that is not owned by ThermoGenesis Holdings is accounted for as a non-controlling interest as the Company has an 80% ownership interest in CARTXpress Bio. Earnings or losses attributable to other stockholders of a consolidated affiliated company are classified separately as "non-controlling interest" in the Company's consolidated statements of operations. Net loss attributable to non-controlling interests reflects only its share of the after-tax earnings or losses of an affiliated company. The Company's condensed consolidated balance sheets reflect non-controlling interests within the equity section.

Recently Adopted Accounting Standards

On January 1, 2022, we adopted Accounting Standards Update (“ASU”) 2020-06 “Debt-Debt with Conversion and Other Options (“Subtopic 470-20”) and Derivatives and Hedging-Contracts in Entity’s Own Equity (“Subtopic 815-40”): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” using the modified retrospective method. ASU 2020-06 provides guidance on how to account for contracts on an entity’s own equity. This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. Specifically, the ASU eliminated the need for the Company to assess whether a contract on the entity’s own equity (1) permits settlement in unregistered shares, (2) whether counterparty rights rank higher than shareholder’s rights, and (3) whether collateral is required. The Company recognized a cumulative effect of $9,739,000 of initially applying the ASU as an adjustment to the January 1, 2022 opening balance of accumulated deficit. Due to the recombination of the equity conversion component of our convertible debt outstanding, the 2022 opening balance of additional paid in capital was reduced by $10,681,000 and the debt discounts of the convertible promissory notes were reduced $942,000.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (“Topic 326”). The ASU introduced a new accounting model, the Current Expected Credit Losses model (“CECL”), which requires earlier recognition of credit losses and additional disclosures related to credit risk. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses at the time the financial asset is originated or acquired. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2022, including interim reporting periods within those annual reporting periods. The Company adopted the standard effective January 1, 2023. Based on the composition of the Company’s trade receivables and unbilled revenue, and expected future losses, the adoption of ASU 2016-13 did not have a material impact on its condensed consolidated financial statements.

Convertible Promissory Note and Revolving Credit Agreement

In March 2017, ThermoGenesis Holdings entered into a Credit Agreement with Boyalife Group (USA), Inc. (the “Lender”), which is owned and controlled by the Company’s Chief Executive Officer and Chairman of our Board of Directors. The Credit Agreement, as amended, grants the Company the right to borrow up to $10,000,000 (the “Loan”) at any time prior to the maturity date. On March 6, 2023, the Company entered into an Amendment No. 2 (the “Amendment to the Note”) to its Second Amended and Restated Convertible Promissory Note with Boyalife Group Inc. (the “Note”), and an Amendment No. 3 to its First Amended and Restated Revolving Credit Agreement with Boyalife Group Inc. The Amendment to the Note amended and extended the maturity date of the Note from March 6, 2023 to December 31, 2023 (the “Maturity Date”) and added to the principal balance of the Note all accrued and unpaid interest at the time of the extension, resulting in an outstanding principal balance of $7,278,000 as of March 6, 2023.

The Company performed a debt extinguishment vs. modification analysis on the Amendment to the Note and determined that the amendment would be considered an extinguishment, due to an increase of more than 10% to the value of the embedded conversion option. However, no gain or loss was recorded in the condensed consolidated statements of operations and comprehensive loss at the time of the Amendment as it was determined that the fair value of the Amendment to the Note and accrued interest was $7,278,000 both before and after the extension.

The Credit Agreement and the Note, as amended provide that the principal and all accrued and unpaid interest under the Loan will be due and payable on the Maturity Date, with payments of interest-only due on the last day of each calendar year. The Loan bears interest at 22% per annum, simple interest. The Company has five business days after the Lender demands payment to pay the interest due before the Loan is considered in default. The Loan can be prepaid in whole or in part by the Company at any time without penalty.

The following summarizes the Note:

	Maturity Date	Stated Interest Rate			Conversion Price		Face Value		Debt Discount			Carrying Value
June 30, 2023	12/31/23		22	%	$	2.65	$	7,278,000	$	(521,000	)	$	6,757,000
December 31, 2022	12/31/23		22	%	$	6.30	$	7,000,000	$	(1,223,000	)	$	5,777,000

The Note includes a down-round anti-dilution provision that lowers its conversion price if the Company sells shares of common stock or issues convertible debt at a lower price per share. Through June 30, 2023, the down-round provision was triggered as noted below:

In January 2023, when the conversion price of the Note was at $6.30 per share, the Company amended a previously outstanding convertible note, resulting in a triggering event lowering the conversion price of the Note to $2.87. The Company determined that it created an incremental value of $2,350,000 which was treated as a discount to the carrying amount of the Note and amortized over its remaining term.

In March 2023, the Company sold shares of common stock and warrants at $2.65 per share, resulting in a down round triggering event lowering the conversion price of the Note to that value. The triggering event created an incremental value of $810,000 which was treated as a discount to the carrying amount of the Note and will be amortized over its remaining term.

A Black-Scholes pricing model was utilized to determine the change in the before and after incremental value of the conversion option at each triggering event, with the following inputs:

	January 2023			March 2023
Conversion price before	$	6.30		$	2.87
Conversion price after	$	2.87		$	2.65
Term (years)		0.09			0.78
Volatility		167	%		168.9	%
Dividend rate		0	%		0	%
Risk free rate		4.46	%		4.20	%

For the three and six months ended June 30, 2023, the Company amortized $258,000 and $3,862,000 of debt discount related to triggering events, compared to $742,000 and $955,000 for the three and six months ended June 30, 2022. In addition to the amortization, the Company also recorded interest expense of $405,000 and $794,000 for the three and six months ended June 30, 2023, compared to $552,000 and $1,102,000 for the three and six months ended June 30, 2022, respectively. The interest payable balance as of June 30, 2023 and December 31, 2022 was $516,000 and $1,492,000, respectively.

Boyalife Genomics

On March 24, 2022, the Company entered into a License and Technology Access Agreement with Boyalife Genomics Tianjin Ltd. (“Boyalife Genomics”), a China-based CDMO and an affiliate of ThermoGenesis’ Chairman and Chief Executive Officer, Chris Xu, Ph.D. The agreement provides for a U.S. license to certain existing and future know-how and other intellectual property relating to cell manufacturing and related processes. The Company plans to develop and operate the CDMO cell therapy manufacturing business through a division named TG Biosynthesis.

Under the terms of the agreement, the Company transferred its remaining 8.64% interest in ImmuneCyte, Inc. to Boyalife Genomics and agreed to pay a running royalty of 7.5% of its annual net sales of products and services that are covered by one or more of Boyalife Genomics’ granted U.S. patents and a royalty of 5.0% of other products and services covered by other licensed intellectual property. In the three and six months ended June 30, 2023, no sales were recorded under the license agreement and no royalty payments were made to Boyalife Genomics.

The Company has the option to renew the lease for up to ten years after the commencement of the initial five-year term.

Operating Lease

Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, we use the Company’s cost of capital based on existing debt instruments. We recognize the expense for this lease on a straight-line basis over the lease term.

The following summarizes the Company’s operating lease:

	June 30, 2023			December 31, 2022

6.         Convertible Promissory Note

July 2019 Note

On July 23, 2019, the Company entered into a private placement with Orbrex (USA) Co. Limited (“Orbrex”), pursuant to which the Company issued and sold to Orbrex an unsecured convertible promissory note in the original principal amount of $1,000,000 (the “July 2019 Note”). The July 2019 Note bears interest at a rate of twenty-four percent (24%) per annum and is payable quarterly in arrears. On January 31, 2023, the Company entered into Amendment No. 3 to the July 2019 Note. The amendment extended the maturity date from January 31, 2023 to July 31, 2023 and changed the fixed conversion price to $2.87 per share.

The Company performed a debt extinguishment vs. modification analysis on the amendment to the July 2019 Note and determined that the extension would be considered an extinguishment, due to an increase of more than 10% to the value of the embedded conversion option. The Company determined that the fair value of the July 2019 Note after the amendment was $1,239,000 representing a $239,000 increase in its fair value. The increase will be recorded as a premium to the July 2019 Note and amortized over the remaining term.

Subsequent to June 30, 2023, the Company entered into an Amendment No. 4 to the July 2019 Note with Orbrex (USA) Co. Limited (the “July 2019 Note Amendment”). The July 2019 Note Amendment amends the July 2019 Note to extend the maturity date of the July 2019 Note from July 31, 2023 to January 31, 2024. The Note Amendment also changed the fixed conversion price to $1.07 per share, provided that in the event that the Company issues shares, options, warrants, or convertible securities, subject to certain exceptions, at an effective price per common share lower than $1.07, then the conversion price will be adjusted to such lower issuance price.

The following summarizes the July 2019 Note:

	Maturity Date	Stated Interest Rate			Conversion Price		Face Value		Debt Discount/ Premium			Carrying Value
June 30, 2023	7/31/2023		24	%	$	2.65	$	397,000	$	7,000		$	404,000
December 31, 2022	7/31/2023		24	%	$	6.30	$	1,000,000	$	(38,000	)	$	962,000

The Note includes a down-round anti-dilution provision that lowers its conversion price if the Company sells shares of common stock or issues convertible debt at a lower price per share. In 2023, the anti-dilution provision was triggered, as noted below:

In March 2023, the Company sold shares of common stock at $2.65 per share, resulting in a down round triggering event lowering the conversion price of the Note to that value. The triggering event created an incremental value of $43,000 which was treated as a discount to the carrying amount of the July 2019 Note and will be amortized over its remaining term.

A Black-Scholes pricing model was utilized to determine the change in the before and after incremental value of the conversion option at each triggering event, with the following inputs:

	March 2023
Conversion price before	$	2.87
Conversion price after	$	2.65
Term (years)		0.36
Volatility		182	%
Dividend rate		0	%
Risk free rate		4.20	%

The Company recorded amortization expense for the July 2019 Note of $(18,000) and $(190,000) for the three and six months ended June 30, 2023, respectively. In addition to the amortization, the Company also recorded interest expense related to the July 2019 Note of $24,000 and $66,000 for the three and six months ended June 30, 2023, compared to $60,000 and $120,000 for the three and six months ended June 30, 2022, respectively.

7.         Stockholders’ Equity

Common Stock

On March 15, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an accredited investor (the “Investor”) pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Offering”) (i) 125,000 shares of its common stock, $0.001 par value (the “Common Shares”), (ii) 946,429 pre-funded warrants to purchase Common Shares at a purchase price of $2.80, and (iii) common stock warrants to purchase up to an aggregate 1,071,429 Common Shares were issued (the “Underlying Shares”). The common stock warrants have an exercise price of $2.65 per share and are exercisable immediately upon issuance and expire five and one-half years following the issuance. The Offering resulted in a total net proceeds of approximately $2.6 million, excluding legal and other transaction fees of $360,000. The Offering closed on March 20, 2023. All 946,429 pre-funded warrants were exercised in the quarter ended June 30, 2023.

In connection with the Offering, the Company entered into a Warrant Amendment Agreement (the "Warrant Amendment Agreement”), dated March 15, 2023, with the Investor, whereby the Company agreed to amend existing warrants, held by the Investor, to purchase up to an aggregate of 158,731 shares of common stock that were previously issued in October 2022. These warrants had an exercise price of $6.30 per share and pursuant to the Warrant Amendment Agreement have been amended to reduce the exercise price to $2.65 per share effective upon the closing of the Offering. During the six months ended June 30, 2023, 158,731 common warrants were exercised. The Company received approximately $421,000 from the exercises of the warrants.

The warrant repricing resulted in an immediate and incremental increase of approximately $50,000 in the estimated fair value of the common warrants issued in the Company’s October 2022 public offering. The common warrants were valued on the date of the warrant repricing using the Black-Scholes option pricing model based on the following assumptions:

	March 2023
Conversion price before	$	6.30
Conversion price after	$	2.65
Term (years)		4.9
Volatility		123	%
Dividend rate		0	%
Risk free rate		4.20	%

On February 3, 2022, the Company entered into Amendment No. 2 to the At the Market Offering Agreement (the “Offering Agreement”) with H.C. Wainwright & Co., LLC to further increase the maximum aggregate offering price of shares of Common Stock that may be offered and sold from time to time under the Offering Agreement from $15,280,000 to $19,555,000, which enables the Company to sell an additional $4,275,000 of shares after taking into account prior sales under the Offering Agreement (the “Additional Shares”). In March 2022, the total offering price was updated to $18,573,000 based on the shares that were currently available on Company’s existing Form S-3. The terms and conditions of the Offering Agreement otherwise remain unchanged. For the six months ended June 30, 2022, the Company sold a total of 20,407 shares of common stock under the Offering Agreement for aggregate gross proceeds of $681,000 at an average selling price of $33.30 per share, resulting in net proceeds of approximately $594,000 after deducting commissions and other transaction costs of approximately $87,000.

Net Loss Per Share

Net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding plus the pre-funded warrants. For the purpose of calculating basic net loss per share, the additional shares of common stock that are issuable upon exercise of the pre-funded warrants have been included since the shares are issuable for a negligible consideration and have no vesting or other contingencies associated with them. As of June 30, 2023, all pre-funded warrants previously issued have been exercised and none are outstanding. The calculation of the basic and diluted earnings per share is the same for all periods presented, as the effect of the potential common stock equivalents noted below is anti-dilutive due to the Company’s net loss position for all periods presented. Anti-dilutive securities consisted of the following at June 30:

	2023		2022
Common stock equivalents of convertible promissory notes and accrued interest		3,108,264		649,667
Warrants		1,239,547		14,518
Stock options		6,400		6,526
Total		4,354,211		670,711

Warrants

A summary of warrant activity for the six months ended June 30, 2023 is as follows:

	Number of Shares			Weighted-Average Exercise Price Per Share		Weighted- Average Remaining Contract Term

Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such Securities and Exchange Commission (“SEC”) rules and regulations and accounting principles applicable for interim periods. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of the results for the periods presented have been included. Events subsequent to the balance sheet date have been evaluated for inclusion in the accompanying condensed consolidated financial statements through the date of issuance.

Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the Company’s fiscal year ending December 31, 2023. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in ThermoGenesis Holdings’ Annual Report on Form 10-K for the year ended December 31, 2022.

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The consolidated financial statements include the accounts of ThermoGenesis Holdings and its wholly-owned subsidiaries, ThermoGenesis Corp. and TotipotentRX Cell Therapy, Pvt. Ltd and ThermoGenesis Corp’s majority-owned subsidiary, CARTXpress Bio, Inc (“CARTXpress Bio”). All significant intercompany accounts and transactions have been eliminated upon consolidation.

The 20% ownership interest of CARTXpress Bio that is not owned by ThermoGenesis Holdings is accounted for as a non-controlling interest as the Company has an 80% ownership interest in CARTXpress Bio. Earnings or losses attributable to other stockholders of a consolidated affiliated company are classified separately as "non-controlling interest" in the Company's consolidated statements of operations. Net loss attributable to non-controlling interests reflects only its share of the after-tax earnings or losses of an affiliated company. The Company's condensed consolidated balance sheets reflect non-controlling interests within the equity section.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Standards

On January 1, 2022, we adopted Accounting Standards Update (“ASU”) 2020-06 “Debt-Debt with Conversion and Other Options (“Subtopic 470-20”) and Derivatives and Hedging-Contracts in Entity’s Own Equity (“Subtopic 815-40”): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” using the modified retrospective method. ASU 2020-06 provides guidance on how to account for contracts on an entity’s own equity. This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. Specifically, the ASU eliminated the need for the Company to assess whether a contract on the entity’s own equity (1) permits settlement in unregistered shares, (2) whether counterparty rights rank higher than shareholder’s rights, and (3) whether collateral is required. The Company recognized a cumulative effect of $9,739,000 of initially applying the ASU as an adjustment to the January 1, 2022 opening balance of accumulated deficit. Due to the recombination of the equity conversion component of our convertible debt outstanding, the 2022 opening balance of additional paid in capital was reduced by $10,681,000 and the debt discounts of the convertible promissory notes were reduced $942,000.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (“Topic 326”). The ASU introduced a new accounting model, the Current Expected Credit Losses model (“CECL”), which requires earlier recognition of credit losses and additional disclosures related to credit risk. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses at the time the financial asset is originated or acquired. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2022, including interim reporting periods within those annual reporting periods. The Company adopted the standard effective January 1, 2023. Based on the composition of the Company’s trade receivables and unbilled revenue, and expected future losses, the adoption of ASU 2016-13 did not have a material impact on its condensed consolidated financial statements.
