AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 1. Overview and Basis of Presentation Overview Harvard Apparatus Regenerative Technology, Inc., formerly Biostage, Inc., (HRGN or the Company) is a clinical-stage biotechnology company focused on the development of regenerative medicine treatments for disorders of the gastro-intestinal system and other organs that result from cancer, trauma or birth defects. The Company’s technology is based on our proprietary cell-therapy platform that uses a patient’s own stem cells to regenerate and restore function to damaged organs. The Company believes that its technology represents a next generation solution for restoring organ function because it allows the patient to regenerate their own organ, thus eliminating the need for human donor or animal transplants, the sacrificing of another of the patient’s own organs or permanent artificial implants. Since inception, the Company has devoted substantially all of its efforts to business planning, research and development, recruiting management and technical staff, and acquiring operating assets. The Company has two business segments and does not have significant costs or assets outside the United States. On October 31, 2013, Harvard Bioscience, Inc., or Harvard Bioscience, contributed its regenerative medicine business assets, plus $ 15 million of cash into HRGN, or the Separation. On November 1, 2013, the spin-off of the Company from Harvard Bioscience was completed. On that date, the Company became an independent company that operates the regenerative medicine business previously owned by Harvard Bioscience. The spin-off was completed through the distribution to Harvard Bioscience stockholders of all the shares of common stock of HRGN, or the Distribution. The Company filed an amendment (the “Certificate of Amendment”) to its Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) with the Secretary of State for the State of Delaware to change its name from Biostage, Inc. to Harvard Apparatus Regenerative Technology, Inc. The Company also amended and restated its Amended and Restated Bylaws, solely to reflect the name change (as amended, the “Third Amended and Restated Bylaws”). The Certificate of Amendment and the Third Amended and Restated Bylaws each became effective on July 20, 2023. In connection with the name change, the Company traded on the OTCQB under the new ticker symbol “HRGN”. The new ticker symbol was effective at the open of the market on July 20, 2023. Longevity Products In the second quarter of 2023, the Company’s subsidiary in Hong Kong, Harvard Apparatus Regenerative Technology Limited, or HRGN LTD, started a longevity products business. The longevity products business plans to include a broad range of products focused on longevity dietary supplements. The Company started selling longevity supplements through HRGN LTD in the third quarter of 2023. These products are marketed to the general public and initially targeted at consumers in the Great China Region through eCommerce (online sales). Going Concern The Company has incurred substantial operating losses since its inception, and as of September 30, 2023 had an accumulated deficit of approximately $ 90.1 million and will require additional financing to fund future operations. The Company expects that its operating cash and short-term investments on-hand as of September 30, 2023 of approximately $ 1.5 million will enable it to fund its operating expenses and capital expenditure requirements into the first quarter of 2024. Therefore, these conditions present risks about the Company’s ability to continue as a going concern. The Company will need to raise additional funds to fund its operations. In the event the Company is unable to raise additional capital from outside sources before or during the first quarter of 2024, it may be forced to curtail or cease its operations. Cash requirements and cash resource needs will vary significantly depending upon the timing of the financial and other resource needs that will be required to complete ongoing development, pre-clinical and clinical testing of product candidates, as well as regulatory efforts and collaborative arrangements necessary for the Company’s product candidates that are currently under development. The Company is currently seeking and will continue to seek financing from other existing and/or new investors to raise necessary funds through a combination of public or private equity offerings. The Company may also pursue debt financings, other financing mechanisms, research grants, or strategic collaborations and licensing arrangements. The Company may not be able to obtain additional financing on favorable terms, if at all. The Company’s operations will be adversely affected if it is unable to raise or obtain needed funding and may materially affect the Company’s ability to continue as a going concern. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern and therefore, the condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amount and classifications of liabilities that may result from the outcome of this uncertainty. 7 2. Summary of Significant Accounting Policies and Recently Issued Accounting Pronouncements Summary of Significant Accounting Policies The accounting policies underlying the accompanying unaudited condensed consolidated financial statements are those set forth in Note 2 to the consolidated financial statements for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K. Prior Period Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. “Selling and marketing” operating expenses was reclassified from “Selling, general and administrative” operating expenses on our condensed consolidated financial statements. Principles of Consolidation The condensed consolidated financial statements include the accounts of HRGN and its subsidiaries, Harvard Apparatus Regenerative Technology Limited (Hong Kong), Harvard Apparatus Regenerative Technology (Hangzhou) Limited (China), Harvard Apparatus Regenerative Technology GmbH (Germany) and HRGN Limited (UK). The functional currency for HRGN and these subsidiaries is the U.S dollar. All intercompany balances and transactions have been eliminated in consolidation. Basis of Presentation The condensed consolidated financial statements reflect the Company’s financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States, or U.S. GAAP. Use of Estimates The process of preparing condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include, but are not limited to, share-based compensation, valuation of warrant liability, accrued expenses and the valuation allowance for deferred income taxes. Actual results could differ from those estimates. Revenue We recognize revenue in accordance with FASB ASC 606, Revenue from Contracts with Customers. We offer consumer products primarily through a third-party online store. Revenue is recognized at a point in time when control of the goods is transferred to the customer, which generally occurs upon the delivery to the customer. For any company direct sales to customers, revenue is recognized at a point in time upon shipment of product or hand-delivery to customer. Revenue also excludes any amounts collected on behalf of third parties, including sales and indirect taxes. We identify a performance obligation as distinct if both the following criteria are true: the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract. Determining the standalone selling price (“SSP”) and allocation of consideration from a contract to the individual performance obligations, and the appropriate timing of revenue recognition, is the result of significant qualitative and quantitative judgments. Management considers a variety of factors such as historical sales, usage rates, costs, and expected margin, which may vary over time depending upon the unique facts and circumstances related to each performance obligation in making these estimates. While changes in the allocation of the SSP between performance obligations will not affect the amount of total revenue recognized for a particular contract, any material changes could impact the timing of revenue recognition, which would have a material effect on our financial position and result of operations. This is because the contract consideration is allocated to each performance obligation, delivered or undelivered, at the inception of the contract based on the SSP of each distinct performance obligation. Cost of Sales Cost of sales primarily consists of the purchase price of consumer products, taxes, inbound and outbound shipping costs. Shipping costs to receive products from our suppliers are recognized as cost of sales when incurred. E-commerce processing and related transaction costs, including those associated with seller transactions, are classified in sales and marketing on our condensed consolidated statements of operations. Sales and Marketing Sales and marketing costs include advertising and payroll and related expenses for personnel engaged in marketing and selling activities. General and Administrative General and administrative expenses primarily consist of costs for corporate functions, including payroll and related expenses; facilities and equipment expenses, such as depreciation and amortization expense and rent; and professional fees. Cash Concentrations The Company maintains its cash balances with a financial institution in federally insured accounts and may periodically have cash balances in excess of insurance limits. The Company maintains its accounts with financial institutions with a high credit rating. The Company has not experienced any losses to date and believes that it is not exposed to any significant credit risk on cash. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents. The Company currently invests available cash in money market funds. Inventory Inventory, consisting of products available for sale, are primarily accounted for using the first-in, first-out method, and are valued at the lower of cost and net realizable value. This valuation requires us to make judgments, based on currently available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, or liquidations, and expected recoverable values of each disposition category. We maintain ownership of our inventory at the third-party warehouse, regardless of whether fulfillment is provided by us or the third-party e-commerce seller, and therefore these products are included in our inventories. Long-term prepaid contracts We have contracted with partners relating to our clinical trial activities. Upon execution of the contracts, we made initial payments as deposits to be held on account and reconciled against final invoices when the clinical trial is substantially completed. Property, Plant and Equipment Property, plant and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets as follows: Schedule of Property Plant and Equipment Estimated Useful Lives Leasehold improvements Shorter of expected useful life or lease term Furniture, machinery and equipment, computer equipment and software 3 - 7 years Maintenance and repairs are charged to expense as incurred, while any additions or improvements are capitalized. Net Loss Per Share Basic net loss per share is calculated by dividing net loss applicable to common stockholders by the weighted-average number of shares outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by adjusting the weighted-average number of shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method. For purposes of the diluted net loss per share calculation, warrants to purchase common stock and stock options are considered to be common stock equivalents, but have been excluded from the calculation of diluted net loss per share, as their effect would be anti-dilutive for all periods presented. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented. Unaudited Interim Financial Information The accompanying interim condensed consolidated balance sheet as of September 30, 2023, condensed consolidated interim statements of operations and stockholders’ equity (deficit) for the three and nine months ended September 30, 2023 and 2022, and cash flows for the nine months ended September 30, 2023 and 2022 are unaudited. The interim unaudited condensed consolidated financial statements have been prepared in accordance with GAAP on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments necessary for a fair statement of the Company’s financial position as of September 30, 2023, its condensed consolidated results of operations and stockholders’ equity (deficit) for the three and nine months ended September 30, 2023 and 2022, and cash flows for the nine months ended September 30, 2023 and 2022. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2023 and 2022 are unaudited. The results for the three and nine months ended September 30, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023, any other interim periods or any future year or period. 8 Recently Adopted Accounting Pronouncements Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s condensed consolidated financial statements upon adoption. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-12) . The new standard requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. It also limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. The Company adopted this standard on January 1, 2023, and the adoption of ASU 2016-13 did not have a material impact on its consolidated financial statements. 3. Fair Value Measurements and Short-term Investments Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value that prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The Company had no assets or liabilities classified as Level 2 or Level 3 as of September 30, 2023 and December 31, 2022. The Company’s short-term investments consist of a certificate of deposit account held to maturity and is carried at amortized cost. The carrying value of financial instruments (consisting of cash, accounts payable, accrued compensation and accrued expenses) is considered to be representative of their respective fair values due to the short-term nature of those instruments. The certificate of deposit matured in October 2023 with the remaining $ 1.2 million released from short-term investments into cash and cash equivalents. The company has investments classified as short term and held-to-maturity on the accompanying condensed consolidated balance sheets. Investment income is included as other income. Investment income for the three months ended September 30, 2023 and September 30, 2022 consists primarily of interest earned of $ 18,000 and $ 0 , respectively. Investment income for the nine months ended September 30, 2023 and September 30, 2022 consists of interest earned of $ 59,000 and $ 0 , respectively. The Company had approximately $ 0.3 million in cash equivalents and $ 1.2 million in short-term investments that consist of a certificate of deposit held to maturity and is carried at amortized cost on the Company’s balance sheet as of September 30, 2023. The Company had $ 1.2 million in cash equivalents and $ 0 in short-term investments that were measured and recorded at fair value on the Company’s balance sheet at December 31, 2022. Schedule of Short Term Investment Securities September 30, 2023 (in thousands) Amortized cost Held-to-maturity Certificate of deposit $ 1,232 Total investment securities $ 1,232 4. Accrued and Other Current Liabilities Accrued and other current liabilities consist of the following: Schedule of Accrued and Other Current Liabilities September 30, December 31, 2023 2022 (in thousands) Research and development $ 39 $ — Advisory costs 300 300 Legal costs — 135 Audit services 84 80 Payroll 110 55 Other liabilities 6 12 Total accrued and other current liabilities $ 539 $ 582 5. Capital Stock Private Placement On April 12, 2023 and on March 31, 2023, the Company entered into Securities Purchase Agreements, each a Purchase Agreement, with new and existing investors, the Investors, pursuant to which the Investors agreed to purchase in a private placement an aggregate of 1,000,967 shares of common stock for the aggregate purchase price of approximately $ 6 million with a purchase price per unit of $ 6.00 . 9 The Company had 1,113,622 warrants to purchase common stock outstanding as of September 30, 2023 with a weighted-average exercise price of $ 4.69 . 6. Series E Convertible Preferred Stock On April 28, 2022, the Company entered into a Preferred Issuance Agreement, or PIA, with Harvard Bioscience, Inc., or HBIO, dated as of April 27, 2022. Pursuant to the PIA, the Company and HBIO agreed that once HBIO had paid at least $ 4.0 million in certain settlement and related legal expenses, to satisfy the Company’s indemnification obligations with respect thereto, in lieu of paying cash, the Company would issue senior convertible preferred stock to HBIO that will contain terms as described in the PIA. On June 10, 2022, following the execution of a subscription agreement and HBIO providing evidence of payment of the requisite $ 4.0 million amount, the Company issued HBIO 4,000 shares of Series E Convertible Preferred Stock, or Series E Preferred Stock, at a price of $ 1,000 per share to satisfy the Company’s related indemnification obligations pertaining to the $ 4.0 million, in lieu of paying cash. On January 18, 2023, HBIO converted 200 Series E Preferred Shares with accrued dividends of $ 9,545 into 31,933 shares of common stock. In connection with the private placement, as of April 12, 2023, the Company had received $ 6.0 million in aggregate proceeds in such private placement. The private placement resulted in gross proceeds of at least $ 4.0 million which triggered the mandatory conversion of all the Company’s outstanding Series E Preferred Stock and related accrued dividends into shares of common stock at a conversion price of $ 6.00 per share. The conversion resulted in 674,693 shares of common stock being issued to the holder of the Series E Preferred Stock. Following such conversion, there are no shares of Series E Preferred Stock outstanding. There were no shares of any of the classes of preferred stock outstanding as of September 30, 2023. Authorized shares for each preferred stock class are as follows: Schedule of Categories of Preferred Stock Authorized Undesignated preferred stock 979,000 Series B convertible preferred stock 1,000,000 Series C convertible preferred stock 4,000 Series D convertible preferred stock 12,000 Series E convertible preferred stock 5,000 7. Share-Based Compensation HRGN Amended and Restated Equity Incentive Plan The Company maintains the Amended and Restated Equity Incentive Plan (the Plan) for the benefit of certain officers, employees, non-employee directors, and other key persons (including consultants and advisory board members). All options and awards granted under the Plan consist of the Company’s shares of common stock. The Company’s policy is to issue stock available from its registered but unissued stock pool through its transfer agent to satisfy stock option exercises and vesting of the restricted stock units. The vesting period for awards is generally four years and the contractual life is ten years . Canceled and forfeited options and awards are available to be reissued under the Plan. The Company’s Plan has 9,098,000 authorized shares to be issued under the Plan. There were 5,035,775 shares available for issuance as of September 30, 2023. The following table summarizes information concerning options outstanding and exercisable: Schedule of Options Outstanding and Exercisable Amount Weighted-average exercise price Weighted-average contractual life (years) Aggregate intrinsic value (in thousands) Outstanding at December 31, 2022 2,516,924 $ 3.95 7.68 $ 6,917 Granted 2,120,913 5.81 Canceled / forfeited ( 593,333 ) 6.12 Outstanding at September 30, 2023 4,044,504 4.61 7.93 6,909 Options exercisable 2,109,399 4.70 7.31 4,605 Options vested and expected to vest 3,945,086 4.65 7.93 6,667 The Company’s outstanding stock options include 773,195 performance-based awards that have vesting provisions subject to the achievement of certain business milestones. Total unrecognized compensation expense for the remaining performance-based awards is approximately $ 2.9 million. No expense has been recognized for these awards as of September 30, 2023 given that the milestone achievements for these awards have not yet been deemed probable for accounting purposes. Aggregate intrinsic value for outstanding options and exercisable options as of September 30, 2023, was approximately $ 6.9 million and $ 4.6 million, respectively, based on the Company’s closing stock price of $ 5.36 per share as of September 30, 2023. As of September 30, 2023, unrecognized compensation cost related to unvested non-performance-based awards amounted to $ 4.4 million, which will be recognized over a weighted-average period of 2.43 years. 10 The Company uses the Black-Scholes option pricing model to value its stock options. The weighted average assumptions for valuing options granted during the nine months ended September 30, 2023 and 2022 were as follows: Schedule of Weighted Average Assumptions Nine months ended September 30, 2023 2022 Risk-free interest rate 3.82 % 2.71 % Expected volatility 125.38 % 1 23.53 % Expected term (in years) 5.8 years 5.8 years Expected dividend yield — % — % The Company recorded share-based compensation expense in the following expense categories of its condensed consolidated statements of operations: Schedule of Share-based Compensation Expense Three months ended September 30, Nine months ended September 30, 2023 2022 2023 2022 (in thousands) (in thousands) Research and development $ 69 $ 72 $ 182 $ 220 General and administrative 466 172 2,672 536 Total $ 535 $ 244 $ 2,854 $ 756 8. Commitments and Contingencies On April 14, 2017, representatives for the estate of an individual plaintiff filed a wrongful death complaint with the Suffolk Superior Court, in the County of Suffolk, Massachusetts, against the Company and other defendants, including Harvard Bioscience, Inc., or HBIO, the former parent of the Company that spun off the Company in 2013, as well as another third party. The complaint sought payment for an unspecified amount of damages and alleged that the plaintiff sustained terminal injuries allegedly caused by products provided by certain of the named defendants and utilized in connection with surgeries performed by third parties in Europe in 2012 and 2013. This lawsuit related to the Company’s first-generation trachea scaffold technology for which the Company discontinued development in 2014, and not to the Company’s current HRGN Esophageal Implant. On April 27, 2022, the Company and HBIO executed a settlement with the plaintiffs (the “Settlement”), which resolves all claims relating to the litigation. The Settlement resulted in the dismissal with prejudice of the wrongful death claim, and neither the Company nor HBIO admit any fault or liability in connection with the claim. The Settlement also resolved any and all claims by and between the parties and the Company’s product liability insurance carriers, which resulted in the dismissal with prejudice of all claims asserted by or against those carriers, the Company and HBIO. In relation to the litigation, the Company paid approximately $ 5.9 million of aggregate costs related to the lawsuit. As of December 31, 2022, all such lawsuit related costs had been paid or otherwise satisfied as provided below. This aggregate amount included the cost of legal and related costs incurred by the Company, which consisted of attorneys’ fees and advisor and specialist costs as part of its defense in this matter. On March 3, 2022, the Company received a cash payment of approximately $ 0.1 million from Medmarc, the Company’s insurance carrier. This amount represented a reimbursement of previously incurred legal costs and was recorded as a reduction to selling, general and administrative expenses during the nine months ended September 30, 2022. 11 With respect to such $ 5.9 million of costs described above, the Company was required to either pay such costs directly or indemnify HBIO as to such amounts it incurs. Of such amounts, the Company anticipated that HBIO would pay an aggregate amount of $ 4.0 million by the end of the second quarter of 2022. With respect to the indemnification obligation of the Company to HBIO pertaining to such costs, the Company and HBIO entered into a Preferred Issuance Agreement dated as of April 27, 2022 (the PIA). In connection with the PIA, the Company and HBIO agreed that once HBIO had paid at least $ 4.0 million in such costs, to satisfy the Company’s indemnification obligations with respect thereto, in lieu of paying cash, the Company would issue senior 8 % convertible preferred stock to HBIO that will contain terms as described in the PIA, including the term sheet attached thereto. On June 10, 2022, following the execution of a subscription agreement and HBIO providing evidence of payment of the requisite $ 4.0 million amount, the Company issued HBIO 4,000 shares of Series E 8 % Convertible Preferred Stock at a price of $ 1,000 per share to satisfy the Company’s related indemnification obligations aggregating $ 4.0 million, which included the accrual for contingency of $ 3.3 million and approximately $ 0.8 million of legal and related costs paid on behalf of the Company by HBIO previously included in accrued expenses. From time to time, the Company may be involved in various claims and legal proceedings arising in the ordinary course of business. Other than the above matter, there are no such matters pending that the Company expects to be material in relation to its business, financial condition, results of operations, or cash flows. 9. Leases The Company leases laboratory and office space and certain equipment with remaining terms ranging from 1 to 2 years. The laboratory and office space arrangement is under a sublease that was renewed in December of 2022 and currently extends through May 31, 2024. This lease automatically renews annually for one-year periods unless the Company or the counterparty provides a notice of termination within one hundred and eighty days prior to May 31 st of each year. On January 5, 2022, the Company executed a four-month sublease agreement for certain laboratory and office space at its Holliston, Massachusetts facility. The Company further extended the sublease agreement on a month-to-month basis until August 31, 2022 when the other party vacated the premises. For the nine months ended September 30, 2022, the Company recorded sublease income of approximately $ 61,000 relating to this agreement. All of the Company’s leases qualify as operating leases. The following table summarizes the presentation of the Company’s operating leases in its condensed consolidated balance sheets: Schedule of Operating Leases in Consolidated Balance Sheets Balance Sheet Classification September 30, 2023 December 31, 2022 (in thousands) Assets: Operating lease assets Right-of-use asset, net $ 103 $ 147 Liabilities: Current portion of operating lease liabilities Current portion of operating lease liabilities 92 99 Operating lease liabilities, net of current portion Operating lease liabilities, net of current portion 11 48 Total operating lease liabilities $ 103 $ 147 The Company recorded operating lease expense in the following categories in its condensed consolidated statements of operations: Schedule of Operating Lease Expense Categories in Consolidated Statements of Operations Three months ended September 30, Nine months ended September 30, 2023 2022 2023 2022 (in thousands) (in thousands) Research and development $ 17 $ 19 $ 51 $ 58 Sales and marketing 5 — 5 — General and administrative 11 11 33 33 Total $ 33 $ 30 $ 89 $ 91 12 Cash paid included in the computation of the operating lease assets and lease liabilities during the three and nine months ended September 30, 2023 amounted to approximately $ 33,000 and $ 89,000 , respectively. Cash paid included in the computation of the operating lease assets and lease liabilities during the three and nine months ended September 30, 2022 amounted to approximately $ 30,000 and $ 91,000 , respectively.

Income Taxes The Company did not record a federal or state income tax provision or benefit for the nine months ended September 30, 2023 and 2022, respectively, due to the expected loss before income taxes to be incurred for the years ended December 31, 2023 and 2022, as well as the Company’s continued maintenance of a full valuation allowance against its net deferred tax assets. 12. Subsequent Events The Company performed a review of events subsequent to the balance sheet through the date the financial statements were issued and determined that there were no such events requiring recognition or disclosure in the financial statements. 13 Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations. Forward Looking Statements This Quarterly Report on Form 10-Q contains statements that are not statements of historical fact and are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”). The forward-looking statements are principally, but not exclusively, contained in “Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Forward-looking statements include, but are not limited to, statements about management’s confidence or expectations and our plans, objectives, expectations and intentions that are not historical facts and the potential impact of COVID-19 on our business and operations. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “could,” “would,” “expects,” “plans,” “anticipates,” “believes,” “goals,” “sees,” “estimates,” “projects,” “predicts,” “intends,” “think,” “potential,” “objectives,” “optimistic,” “strategy,” and similar expressions intended to identify forward-looking statements. These statements reflect our current views with respect to future events and are based on assumptions and subject to risks and uncertainties. Given these uncertainties, you should not place undue reliance on these forward-looking statements. Factors that may cause our actual results to differ materially from those in the forward-looking statements include our ability to access debt and equity markets and raise additional funds when needed; the success of our collaborations, clinical trials and pre-clinical development efforts and programs, which success may not be achieved on a timely basis or at all; our ability to obtain and maintain regulatory approval for our implant products, bioreactors, scaffolds and other devices we pursue, including for the esophagus or airway, which approvals may not be obtained on a timely basis or at all; the number of patients who can be treated with our products; the amount and timing of costs associated with our development of implant products, bioreactors, scaffolds and other devices; our failure to comply with regulations and any changes in regulations; unpredictable difficulties or delays in the development of new technology; our collaborators or other third parties we contract with, including with respect to conducting any clinical trial or pre-clinical development efforts, not devoting sufficient time and resources to successfully carry out their duties or meet expected deadlines; our ability to attract and retain qualified personnel and key employees and retain senior management; potential liability exposure with respect to our products; the availability and price of acceptable raw materials and components from third-party suppliers; difficulties in obtaining or retaining the management and other human resource competencies that we need to achieve our business objectives; increased competition in the field of regenerative medicine and bioengineering, and the financial resources of our competitors; our ability to obtain and maintain intellectual property protection for our device and product candidates; our inability to implement our growth strategy; the control our principal stockholders can exert based on holding a majority of voting power; plus factors described under the heading “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (the “SEC”) on March 30, 2023 or described in our other public filings. Our results may also be affected by factors of which we are not currently aware. We may not update these forward-looking statements, even though our situation may change in the future, unless we have obligations under the federal securities laws to update and disclose material developments related to previously disclosed information. Harvard Apparatus Regenerative Technology, Inc. is referred to herein as “we,” “our,” “us”, and “the Company”. Business Overview We are a clinical-stage biotechnology company focused on the development of regenerative medicine treatments for disorders of the gastro-intestinal system and other organs that result from cancer, trauma or birth defects. Our technology is based on our proprietary cell-therapy platform that uses a patient’s own stem cells to regenerate and restore function to damaged organs. We believe that our technology represents a next generation solution for restoring organ function because it allows the patient to regenerate their own organ, thus eliminating the need for human donor or animal transplants, the sacrificing of another of the patient’s own organs or permanent artificial implants. 14 We conducted the world’s first successful regeneration of the esophagus in a cancer patient in August 2017. This surgery was performed by Dr. Dennis Wigle, Chair of Thoracic Surgery at the Mayo Clinic in a patient with esophageal cancer. The results were published in the Journal of Thoracic Oncology Clinical and Research Reports in August 2021. The procedure demonstrated that using HRGN’s technology, we were able to successfully regenerate esophageal tissue, including the mucosal lining, to restore the integrity, continuity and functionality of the esophageal tube. This successful first-in-human experience, plus the research we have performed on 45 pigs, led the U.S. Food and Drug Administration (“FDA”) to approve our 10-patient combined phase 1 and phase 2 clinical trial. This combination trial will measure both safety and efficacy in the patient population. We were incorporated and commenced operations on November 1, 2013 as a result of a spin-off from Harvard Bioscience, Inc., or Harvard Bioscience. On that date, we became an independent company that operates the regenerative medicine business previously owned by Harvard Bioscience. The spin-off was completed through the distribution of all the shares of common stock of HRGN to Harvard Bioscience stockholders. We continue to assess the market and regulatory approval pathway in China as to our implant products. We are not certain at this time as to which market, including U.S. or China for example, may provide the most viable initial pathway for regulatory approval to a commercial product. This will depend on a number of factors, including the approval and development processes, related costs, ability to raise capital and the terms and conditions thereof, among other factors. Any development and capital raising efforts in China may include a joint venture in relation to our Hong Kong subsidiary, and would also involve a number of commercial variables, including rights and obligations pertaining to licensing, development, and financing, among others. Our failure to receive or obtain such clearances or approvals on a timely basis or at all, whether that be in the U.S., China or otherwise, would have an adverse effect on our results of operations. We filed an amendment (the “Certificate of Amendment”) to our Amended and Restated Certificate of Incorporation with the Secretary of State for the State of Delaware to change our name from Biostage, Inc. to Harvard Apparatus Regenerative Technology, Inc. We also amended and restated our Amended and Restated Bylaws, solely to reflect the name change (as amended, the “Third Amended and Restated Bylaws”). The Certificate of Amendment and the Third Amended and Restated Bylaws each became effective on July 20, 2023. Since our incorporation, we have devoted substantially all of our resources to developing our programs, building our intellectual property portfolio, business planning, raising capital and providing selling, general and administrative support for these operations. To date, we have financed our operations with proceeds from the sales of common stock and preferred stock. In December 2017, we sold the inventory and rights to manufacture and sell research-only versions of our bioreactors to Harvard Bioscience. We have contracted with IQVIA, a leading global provider of advanced analytics, technology solutions and clinical research services to the life sciences industry, as the contract research organization (CRO) to manage our first clinical trial. We activated the first clinical trial site and started screening patients in the third quarter of 2023. Our product candidates are currently in development and have not yet received regulatory approval for sale anywhere in the world. In the second quarter of 2023, the Company’s subsidiary in Hong Kong, Harvard Apparatus Regenerative Technology Limited, or HRGN LTD, started a longevity products business. The longevity products business plans to include a broad range of products focused on personal healthcare including longevity dietary supplements. The Company started selling longevity supplements through the Hong Kong subsidiary in the third quarter of 2023. These products are marketed to the general public and initially targeted at consumers in the Great China Region through eCommerce (online sales). Financial Condition and Need for Additional Funds We expect to continue to incur operating losses and negative cash flows from operations for 2023 and in future years. Operating Losses and Cash Requirements We have incurred substantial operating losses since our inception, and as of September 30, 2023 had an accumulated deficit of approximately $90.1 million and will require additional financing to fund future operations. We expect that our operating cash and short-term investments on-hand as of September 30, 2023 of approximately $1.5 million will enable us to fund our operating expenses and capital expenditure requirements into the first quarter of 2024. We expect to continue to incur operating losses and negative cash flows from operations for 2023 and in future years. Therefore, as disclosed in Note 1 to our Condensed Consolidated Financial Statements appearing elsewhere in this Quarterly Report on Form 10-Q, these conditions raise substantial doubt about our ability to continue as a going concern. We will need to raise additional funds to fund our operations. In the event we do not raise additional capital from outside sources before or during the first quarter of 2024, we may be forced to curtail or cease our operations. 15 Cash requirements and cash resource needs will vary significantly depending upon the timing of the financial and other resource needs that will be required to complete ongoing development, pre-clinical and clinical testing of product candidates, as well as regulatory efforts and collaborative arrangements necessary for our product candidates that are currently under development. We are currently seeking and will continue to seek financings from other existing and/or new investors to raise necessary funds through a combination of public or private equity offerings. We may also pursue debt financings, other financing mechanisms, research grants, or strategic collaborations and licensing arrangements. We may not be able to obtain additional financing on favorable terms, if at all. Our operations will be adversely affected if we are unable to raise or obtain needed funding and may materially affect our ability to continue as a going concern. Our condensed consolidated financial statements have been prepared assuming that we will continue as a going concern and therefore, the condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amount and classifications of liabilities that may result from the outcome of this uncertainty. Components of Operating Loss Product revenue . Product revenue consists of longevity product sales, launched in the Asia region in the third quarter of 2023. We had not generated any revenue prior to the launch of our longevity products. Research and development expense . Research and development expense consists of salaries and related expenses, including share-based compensation, for personnel and contracted consultants and various materials and other costs to develop our new products, primarily: synthetic scaffolds, including investigation and development of materials and investigation and optimization of cellularization, as well as studies of cells and cell behavior. Other research and development expenses include the costs of outside service providers and material costs for prototype and test units and outside laboratories and testing facilities performing cell growth and materials experiments, as well as the costs of all other preclinical research and testing including animal studies and expenses related to potential patents. We expense research and development costs as incurred. Sales and marketing expense . Sales and marketing costs include advertising and payroll and related expenses for personnel engaged in marketing and selling activities. General and administrative expense . Selling, general and administrative expense consists primarily of salaries and other related expenses, including share-based compensation. Other costs include professional fees for legal and accounting services, insurance, investor relations and facility costs. Sublease income. On January 5, 2022, we executed a four-month sublease agreement for certain laboratory and office space at its Holliston, Massachusetts facility. We further extended the sublease agreement to a month-to-month basis until August 31, 2022 when the other party vacated the premises. We have no sublease agreements generating sublease income as of September 30, 2023. Other income, net. Other income, net, consists primarily of interest income and the changes in fair value of our warrant liability from the change in the fair value of common stock warrants classified as liability awards during the nine months ended September 30, 2022. We previously used the Black-Scholes pricing model to value the related warrant liability. In February of 2022, the underlying common stock warrants expired unexercised. Critical Accounting Policies and Estimates Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have prepared in accordance with accounting principles generally accepted in the United States, or. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the expenses during the reporting periods. We evaluate these estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Our actual results may differ materially from these estimates under different assumptions or conditions. While our significant accounting policies are discussed in more detail in Note 2 to our Condensed Consolidated Financial Statements appearing elsewhere in this Quarterly Report on Form 10-Q, we believe that the following accounting policies are the most critical for fully understanding and evaluating our financial condition and results of operations. 16 Share-based Compensation We account for our share-based compensation in accordance with the fair value recognition provisions of current authoritative guidance. Share-based awards, including stock options, are measured at fair value as of the grant date and recognized as expense over the requisite service period (generally the vesting period), which we have elected to amortize on a straight-line basis. Expense on share-based awards for which vesting is performance or milestone based is recognized on a straight-line basis from the date when we determine the achievement of the milestone is probable to the vesting/milestone achievement date. Since share-based compensation expense is based on awards ultimately expected to vest, it has been reduced by an estimate for future forfeitures. Until December 31, 2022, we estimated forfeitures at the time of grant and would revise our estimate, if necessary, in subsequent periods. As of January 1, 2023, we account for forfeitures as they occur. We estimate the fair value of options granted using the Black-Scholes option valuation model. Significant judgment is required in determining the proper assumptions used in this model. The assumptions used include the risk-free interest rate, expected term, expected volatility, and expected dividend yield. We base our assumptions on historical data when available or, when not available, on a peer group of companies. However, these assumptions consist of estimates of future market conditions, which are inherently uncertain and subject to our judgment, and therefore any changes in assumptions could significantly impact the future grant date fair value of share-based awards. Warrant Liability Most of the warrants to purchase shares of our common stock have been classified on our condensed consolidated balance sheets as equity. We classify warrants as a liability in our condensed consolidated balance sheets if the warrant is a free-standing financial instrument that may require us to transfer cash consideration upon exercise and that cash transfer event would be out of our control. Such a “liability warrant” is initially recorded at fair value on the date of grant using the Black-Scholes model, net of issuance costs, and it is subsequently re-measured to fair value at each subsequent balance sheet date. Changes in fair value of the warrants is recognized as a component of other expense in the condensed consolidated statements of operations. The warrants classified as a liability expired unexercised during the nine months ended September 30, 2022 and the remaining liability on the expiration date of approximately $2,000 was recognized as other income. Results of Operations The following table summarizes the results of our operations for the three and nine months ended September 30, 2023 and 2022 (in thousands): Three months ended September 30, Change 2023 vs. 2022 Nine months ended September 30, Change 2023 vs. 2022 2023 2022 Change % 2023 2022 Change % Product revenue $ 40 $ — $ 40 100 % $ 40 $ — $ 40 100 % Operating expenses Cost of sales 13 — 13 100 % 13 — 13 100 % Research and development 339 369 (30 ) (8) % 2,414 998 1,416 142 % Sales and marketing 143 — 143 100 % 198 — 198 100 % General and administrative 1,169 711 458 64 % 4,577 3,662 915 25 % Total operating expenses 1,664 1,080 584 54 % 7,202 4,660 2,542 55 % Other income Sublease (expense) income (5 ) 26 (31 ) nm % (5 ) 87 (92 ) nm % Other income (expense), net 14 (2 ) 16 nm % 48 (5 ) 53 nm % Total other income, net 9 24 (15 ) (63) % 43 82 (39 ) (48 )% Net loss $ (1,615 ) $ (1,056 ) $ (559 ) 53 % $ (7,119 ) $ (4,578 ) $ (2,541 ) 56 % nm = not meaningful 17 Comparison of the three months ended September 30, 2023 and September 30, 2022 Product Revenue Product revenue was $40,000 and zero for the three months ended September 30, 2023 and 2022, respectively. Product revenue consists of longevity product sales, launched in the Asia region in the third quarter of 2023. We had not generated any revenue prior to the launch of our longevity products. Cost of Sales Cost of sales was $13,000 and zero for the three months ended September 30, 2023 and 2022, respectively. For the three months ended September 30, 2023, cost of sales consists of the purchase price of consumer products, taxes, inbound and outbound shipping costs. Research and Development Expense Research and development expense decreased approximately $30,000, or 8%, to approximately $0.3 million for the three months ended September 30, 2023 as compared to approximately $0.4 million for the three months ended September 30, 2022. This decrease was primarily due to lower advisory costs for the three months ended September 30, 2023. Sales and Marketing Expense HRGN Limited launched its longevity products Business in the second quarter of 2023 so there were no prior comparable period costs. Selling and marketing expense was $0.1 million for the three months ended September 30, 2023 as compared to zero for the three months ended September 30, 2022. General and Administrative Expense General and administrative expense increased approximately $0.5 million, or 64%, to approximately $1.2 million for the three months ended September 30, 2023 as compared to approximately $0.7 million for the three months ended September 30, 2022. This increase was primarily due to share-based compensation expense of $0.3 million from the vesting of time-based awards in the third quarter of 2023 and increased headcount related costs of approximately $0.2 million. Sublease (expense) income On January 5, 2022, we executed a four-month sublease agreement for certain laboratory and office space at our Holliston, Massachusetts facility. We further extended the sublease agreement on a month-to-month basis until August 31, 2022 when the other party vacated the premises. For the three months ended September 30, 2022, we recorded sublease income of approximately $26,000 relating to this agreement. We have no sublease agreements generating sublease income as of September 30, 2023. In 2023, we refunded $5,000 of a deposit not utilized, which was recorded as sublease income in 2022. Other income, net During the three months ended September 30, 2023, we recorded interest income of approximately $18,000 earned from our money market account and certificate of deposit offset by approximately $4,000 on insurance installment payments. During the three months ended September 30, 2022, we recorded interest expense of approximately $2,000 on insurance installment payments. Comparison of the nine months ended September 30, 2023 and September 30, 2022 Product Revenue Product revenue was $40,000 and zero for the nine months ended September 30, 2023 and 2022, respectively. Product revenue consists of longevity product sales, launched in the Asia region in the third quarter of 2023. We had not generated any revenue prior to the launch of our longevity products. 18 Cost of Sales Cost of sales was $13,000 and zero for the nine months ended September 30, 2023 and 2022, respectively. For the nine months ended September 30, 2023, cost of sales consists of the purchase price of consumer products, taxes, inbound and outbound shipping costs. Research and Development Expense Research and development expense increased approximately $1.4 million, or 142%, to approximately $2.4 million for the nine months ended September 30, 2023 as compared to approximately $1.0 million for the nine months ended September 30, 2022. This increase was primarily due to preclinical trial activities to increase our product pipeline and clinical trial activities resulting in our first site activation in the third quarter of 2023. Sales and Marketing Expense HRGN Limited launched its longevity products Business in the second quarter of 2023 so there were no prior period costs. Selling and marketing expense was $0.2 million for the nine months ended September 30, 2023 as compared to zero for the nine months ended September 30, 2022. General and Administrative Expense General and administrative expense increased approximately $0.9 million, or 25%, to approximately $4.6 million for the nine months ended September 30, 2023 as compared to approximately $3.7 million for the nine months ended September 30, 2022. This increase was primarily due to share-based compensation expense of $2.1 million from the vesting of performance based awards in the first half of 2023 and increased headcount related costs of approximately $0.4 million offset by a decrease of approximately $0.3 million for supporting our ongoing public company requirements and reduced legal and related costs of approximately $1.3 million relating to the completion of litigation for a wrongful death complaint and related matters more fully described in Note 8 to our condensed consolidated financial statements. Sublease (expense) income On January 5, 2022, we executed a four-month sublease agreement for certain laboratory and office space at our Holliston, Massachusetts facility. We further extended the sublease agreement on a month-to-month basis until August 31, 2022 when the other party vacated the premises. For the nine months ended September 30, 2022, we recorded sublease income of approximately $87,000 relating to this agreement. We have no sublease agreements generating sublease income as of September 30, 2023. In 2023, we refunded $5,000 of a deposit not utilized, which was recorded as sublease income in 2022. Other income, net During the nine months ended September 30, 2023, we recorded interest income of approximately $59,000 earned from our money market account and certificate of deposit offset by approximately $11,000 on insurance installment payments. During the nine months ended September 30, 2022, we recorded a gain on expiration of the common share warrants of approximately $2,000 in other expense, net as they expired unexercised in February 2022. We also recorded interest expense of approximately $7,000 on insurance installment payments. Liquidity and Capital Resources Sources of liquidity. We have incurred operating losses since inception, and as of September 30, 2023, we had an accumulated deficit of approximately $90.1 million. We are currently investing significant resources in the development and commercialization of our product candidates for use by clinicians and researchers in the fields of regenerative medicine and bioengineering. As a result, we expect to incur operating losses and negative operating cash flows for the foreseeable future. 19 The following table sets forth the primary uses of cash for the three months ended September 30, 2023 and 2022 (in thousands): Nine Months Ended September 30, 2023 2022 Net cash used in operating activities $ (5,721 ) $ (3,373 ) Net cash used by investing activities $ (1,243 ) $ (8 ) Net cash provided by financing activities $ 5,992 $ 5,060 Comparison of nine months ended September 30, 2023 and 2022 Operating activities.
