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, 2021 filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2022 or described in our other public filings. Our results may also be affected by factors of which we are not currently aware.

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, as well as the ongoing impact of the COVID-19 pandemic, 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.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">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 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 did not recognize any revenues during the quarters ended March 31, 2022 and 2021.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">Our product candidates are currently in development and have not yet received regulatory approval for sale anywhere in the world.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Financial Condition and Need for Additional Funds</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">We expect to continue to incur operating losses and negative cash flows from operations for 2022 and in future years.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Operating Losses and Cash Requirements</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">We have incurred substantial operating losses since our inception, and as of March 31, 2022 had an accumulated deficit of approximately $79.1 million and will require additional financing to fund future operations. We expect that our operating cash on-hand as of March 31, 2022 of approximately $0.7 million, along with cash proceeds of approximately $5.1 million received through May 16, 2022 from a private placement from new and existing investors, will enable us to fund our operating expenses and capital expenditure requirements into the first quarter of 2023. We expect to continue to incur operating losses and negative cash flows from operations for 2022 and in future years. Therefore, as disclosed in Note 1 to our Consolidated Financial Statements, these conditions raise substantial doubt about our ability to continue as a going concern.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;">We will need to raise additional funds to fund our operations.

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.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;">While our significant accounting policies are discussed in more detail in Note 2 to our 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.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt;">Share-based Compensation</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;">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. We estimate forfeitures at the time of grant and revise our estimate, if necessary, in subsequent periods. 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. </p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;"><span style="text-transform:uppercase;">18</span></p></div></div> <div style="background-color:#000000;clear:both;height:2pt;page-break-after:always;width:88.24%;border:0;margin:30pt 5.88% 30pt 5.88%;"/><div style="max-width:100%;padding-left:5.88%;padding-right:5.88%;position:relative;"><div style="margin-top:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 30pt 0pt;"><a href="#TOC"><span style="font-style:normal;font-weight:normal;">Table of Contents</span></a></p></div><div style="clear:both;max-width:100%;position:relative;min-height:11.5pt;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;">We base our assumptions on historical data when available or, when not available, on a peer group of companies.

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 income (expense) in the condensed consolidated statements of operations. The warrants classified as a liability expired unexercised during the three months ended March 31, 2022 and the remaining liability on the expiration date of approximately $2,000 was recognized as

Other than the ongoing civil lawsuit described in Item 3 of Part I of our Annual Report on Form 10-K filed with the SEC on March 31, 2021 and in our Form 8-K filed with the SEC on April 27, 2022, there are no such matters pending that we expect to be material in relation to our business, financial condition, and results of operations or cash flows.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;">As previously disclosed, including in the Form 8-K filing referenced above, 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 us 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 relates to our first-generation trachea scaffold technology for which we discontinued development in 2014, and not to our current Biostage Esophageal Implant.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">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 will result in the dismissal with prejudice of the wrongful death claim, and neither we nor HBIO admit any fault or liability in connection with the claim. The Settlement also resolves any and all claims by and between the parties and our products liability insurance carriers, which will result in the dismissal with prejudice of all claims asserted by or against those carriers, the Company and HBIO. However, based on review of the circumstances surrounding the Settlement, we recorded an accrual for the contingency matter of approximately $3.3 million in general and administrative expenses during the year ended December 31, 2021.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">In relation to the litigation, we estimate that we will incur an aggregate of approximately $6.0 million of costs, of which, approximately $5.5 million remains unpaid. This amount includes the cost of both the accrual for this matter of $3.3 million and approximately $2.7 million of legal and related costs incurred by us which consist of attorney’s fees and advisor and specialist costs as part of our defense in this matter. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">For the three months ended March, 31, 2022, we incurred legal and related costs of approximately $1.3 million recorded in general and administrative expenses. On March 3, 2022, we received a cash payment of approximately $0.1 million from Medmarc, our insurance carrier. This amount represented a reimbursement of previously incurred legal costs and was recorded as a reduction to general and administrative expenses during the three months ended March 31, 2022.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">We have incurred an additional $0.2 million of legal and related costs subsequent to March 31, 2022. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;"><span style="background:#ffffff;">With respect to such $6.0 million of estimated costs described above, we are required to either pay such costs directly or indemnify HBIO as to such amounts it incurs. Of such amounts, we anticipate that HBIO will pay an aggregate amount of $4.0 million by the end of the second quarter of 2022. With respect to this indemnification obligation of the Company to HBIO pertaining to such costs, we and HBIO have entered into a Preferred Issuance Agreement dated as of April 27, 2022, or the “PIA”. In connection with the PIA, we and HBIO have agreed that once HBIO has paid at least $4.0 million in such costs, to satisfy our indemnification obligations with respect thereto, in lieu of paying cash, we will issue senior convertible preferred stock to HBIO that will contain terms as described in the PIA. In addition, as described above, we will continue to pay, or otherwise indemnify HBIO as to its payment thereof, the remaining legal expenses incurred in connection with the litigation, Settlement and related matters. Assuming the issuance of such preferred stock, we currently estimate that the remaining aggregate amount of such costs we will be obligated to pay will be approximately $1.5 million.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="background:#ffffff;">The issuance of such preferred stock, and the terms thereof, are subject to the negotiation and execution of definitive documents relating thereto, but in accordance with the PIA, such preferred stock will automatically convert into shares of our common stock upon the earlier to occur of our offering that includes common stock (whether private placement or public offering) that coincides with its uplisting onto NASDAQ, its public offering that includes common stock following the issuance of the preferred stock, or its initial private placement that includes common stock following the issuance of the preferred stock in the event the gross proceeds of such private placement are $4,000,000 or more. In addition, in accordance with the PIA, such preferred stock will also be subject to optional conversion by HBIO at any time and prior to any such automatic or optional conversion, will have dividends paid quarterly in </span></p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;"><span style="text-transform:uppercase;">22</span></p></div></div> <div style="background-color:#000000;clear:both;height:2pt;page-break-after:always;width:88.24%;border:0;margin:30pt 5.88% 30pt 5.88%;"/><div style="max-width:100%;padding-left:5.88%;padding-right:5.88%;position:relative;"><div style="margin-top:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 30pt 0pt;"><a href="#TOC"><span style="font-style:normal;font-weight:normal;">Table of Contents</span></a></p></div><div style="clear:both;max-width:100%;position:relative;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;"><span style="background:#ffffff;">additional shares of preferred stock at a rate of 8% per annum.

While giving consideration to cash proceeds of approximately $5.1 million received through May 16, 2022 from a private placement from new and existing investors, we will need to raise additional capital in the first quarter of 2023 and beyond to fund operations. If we do not raise additional capital from outside sources during the first quarter of 2023, we may be forced to further curtail or cease our operations. Based on these circumstances, our ability to continue as a going concern is at risk as our independent registered public accounting firm included a “going concern” qualification as to our ability to continue as a going concern in their audit report dated March 31, 2022, included in our Form 10-K for the year ended December 31, 2021, which was filed with the SEC on March 31, 2022. Our cash requirements and cash resources will vary significantly depending upon the timing, and the financial and other resources that will be required to complete ongoing development and pre-clinical and clinical testing of our product candidates, regulatory efforts and collaborative arrangements necessary for our product candidates that are currently under development. In addition to development and other costs, we expect to incur capital expenditures from time to time. These capital expenditures will be influenced by our regulatory compliance efforts, our success, if any, at developing collaborative arrangements with strategic partners, our needs for additional facilities and capital equipment and the growth, if any, of our business in general. We will require additional funding to continue our anticipated operations and support our capital and operating needs. 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, strategic collaborations and licensing arrangements. We may not be able to obtain additional financing on terms favorable to us, if at all. In addition, general market conditions, including the effect of the COVID-19 pandemic on financial markets, as well as the effects of laws and regulations on foreign investment in the United States under the jurisdiction of the Committee on Foreign Investment in the United States (CFIUS), and other agencies and related regulations, including the Foreign Investment Risk Review Modernization Act (FIRRMA), adopted in August 2018, may make it difficult for us to seek financing from the capital markets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;">Any additional equity financings could result in significant dilution to our stockholders and possible restrictions on subsequent financings. Debt financing, if available, could result in agreements that include covenants limiting or restricting our ability to take certain actions, such as incurring additional debt, making capital expenditures or paying dividends. Other financing mechanisms may involve selling intellectual property rights, payment of royalties or participation in our revenue or cash flow. In addition, in order to raise additional funds through strategic collaborations or licensing arrangements, we may be required to relinquish certain rights to some or all of our technologies or product candidates. If we cannot raise funds or engage strategic partners on acceptable terms when needed, we may not be able to continue our research and development activities, develop or enhance our product candidates, take advantage of future opportunities, grow our business, respond to competitive pressures or unanticipated requirements, or at worst may be forced to curtail or cease our operations.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New
