NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. Overview and Basis of Presentation

Overview

Biostage, Inc. (Biostage or the Company) is a clinical-stage biotechnology company developing bioengineered organ implants based on the Company’s novel Cellspan^TM technology. The Company’s Cellspan technology is comprised of a biocompatible scaffold that is seeded with the recipient’s own stem cells. The Company believes that this technology may prove to be effective for treating patients across a number of life-threatening medical indications who currently have unmet medical needs. The Company is currently developing its Cellspan technology to treat life-threatening conditions of the esophagus, bronchus and trachea with the objective of dramatically improving the treatment paradigm for those patients. 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 one business segment and does not have significant costs or assets outside the United States.

On October 31, 2013, Harvard Bioscience, Inc. (Harvard Bioscience) contributed its regenerative medicine business assets, plus $15 million of cash, into Biostage (formerly “Harvard Apparatus Regenerative Technologies”) in a spin-off transaction. 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 of all the shares of common stock of Biostage to stockholders of Harvard Bioscience (the “HBIO Distribution”).

The Company’s common stock is currently traded on the OTCQB Venture Market under the symbol “BSTG”.

Basis of Presentation

The 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 (GAAP).

Use of Estimates

The preparation of the Company’s consolidated financial statements requires the Company to make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities, equity, expenses and related disclosures. On an ongoing basis the Company evaluates its estimates, judgments and methodologies. The Company bases its estimates on historical experience and on various other assumptions that the Company believes are reasonable, the results of which form the basis for making judgments about the carrying values of assets, liabilities and equity and the amount of expenses. Actual results may differ from these estimates.

Going Concern

The Company has incurred substantial operating losses since its inception, and future losses are anticipated. As of June 30, 2020, the Company has an accumulated deficit of approximately $67.3 million and will require additional financing to fund future operations. The Company expects that its operating cash on-hand at June 30, 2020 of $0.6 million, along with net proceeds received subsequent to the end of the quarter of approximately $0.2 million from the issuance of 58,932 shares of its common stock from the exercise of 58,932 previously issued warrants at $3.70 per share will enable it to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2020. In addition, on January 30, 2020 the World Health Organization declared the COVID-19 outbreak a “Public Health Emergency of International Concern” and on March 11, 2020, declared it a pandemic. The full extent to which the COVID-19 pandemic may directly or indirectly impact our business, results of operations and financial condition, expenses, clinical trial, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain it or treat COVID-19, as well as the economic impact that may impact the Company. Therefore, these conditions have caused management to determine there is substantial doubt 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 does not raise additional capital from outside sources before the fourth quarter of 2020, 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 pre-clinical and clinical testing of products, research and development, and regulatory efforts and collaborative arrangements necessary for the Company’s products that are currently under development. In addition, the Company received $404,221 of loan proceeds in May 2020 as part of the Paycheck Protection Program (PPP), established as part of the Coronavirus Aid, Relief, and Economic Security (CARES) Act. Based on the current loan terms, payments begin in November 2020 subject to the Company meeting the partial or full loan forgiveness requirements. See Note 4. The Company is 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. 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.

8

The Company’s operations will be adversely affected if it is unable to raise or obtain needed funding and such circumstance may materially affect the Company’s ability to continue as a going concern. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern and therefore, the 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.

Net Loss Per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the sum of the weighted average number of common shares outstanding during the period and, if dilutive, the weighted average number of potential shares of common stock, including the assumed exercise of stock options, warrants, and the impact of unvested restricted stock.

The Company applies the two-class method to calculate basic and diluted net loss per share attributable to common stockholders as its warrants to purchase common stock are participating securities.

The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. However, the two-class method does not impact the net loss per share of common stock as the Company has been in a net loss position and the warrant holders do not participate in losses.

Basic and diluted shares outstanding are the same for each period presented as all common stock equivalents would be antidilutive due to the net losses incurred. 

Unaudited Interim Financial Information

The accompanying interim consolidated balance sheet as of June 30, 2020, consolidated interim statements of operations and stockholders’ equity for the three and six months ended June 30, 2020 and 2019, and consolidated statements of cash flows for the six months ended June 30, 2020 and 2019 are unaudited. The interim unaudited 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 June 30, 2020, its consolidated results of operations and consolidated stockholders’ equity for the three and six month periods ended June 30, 2020 and 2019 and consolidated statements of cash flows for the six month periods ended June 30, 2020 and 2019. The financial data and other information disclosed in these notes related to the three and six-month periods ended June 30, 2020 and 2019 are unaudited. The results for the three and six months ended June 30, 2020 are not necessarily indicative of results to be expected for the year ending December 31, 2020, any other interim periods or any future year or period.

2. Summary of Significant Accounting Policies and Recently Issued Accounting Pronouncements

Summary of Significant Accounting Policies

The accounting policies underlying the accompanying unaudited consolidated financial statements are those set forth in Note 2 to the consolidated financial statements for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K.

SBIR Award

On March 28, 2018, the Company was awarded a Fast-Track Small Business Innovation Research (SBIR) grant by the Eunice Kennedy National Institute of Child Health and Human Development (NICHD) of the National Institutes of Health to support testing of pediatric Cellspan Esophageal Implants. The award for Phase I, which was earned over the nine months ended September 30, 2018, provided for the reimbursement for up to approximately $0.2 million of qualified research and development costs. 

On October 26, 2018, the Company was awarded Phase II of the SBIR grant totaling $1.1 million to support expenses for development, testing, and translation to the clinic through September 2019. As of September 30, 2019, the Company had expended $0.6 million of the $1.1 million awarded, and in December 2019 submitted a modified Phase II grant development plan totaling $1.0 million, including $0.5 million unspent from the Phase 2 grant awarded and an additional $0.5 million for the next year of the project, subject to the NICHD approval. This modified development plan was approved by the NICHD on August 3, 2020. See Note 11. The SBIR grant has the potential to provide a total award of approximately $1.8 million, of which approximately $0.8 million has been recognized to date. The Company did not recognize grant income from Phase II of the SBIR grant for the three and six months ended June 30, 2020.

9

Grant income is recognized when qualified research and development costs are incurred and recorded in other income (expense), net in the consolidated statements of operations. When evaluating grant revenue from the SBIR grant, the Company considered accounting requirements under the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 606, Revenue From Contracts With Customers. The Company concluded that ASC 606 did not apply as there is no exchange of goods or services or an exchange of intellectual property between the parties; therefore, the Company presents grant income in other income.

Restricted Cash

Restricted cash consists of $50,000 held as collateral for the Company’s credit card program as of June 30, 2020 and December 31, 2019. The Company’s consolidated statements of cash flows include restricted cash with cash when reconciling the beginning-of-period and end-of-period total amounts shown on such statements.

A reconciliation of the cash and restricted cash reported within the balance sheet that sum to the total of the same amounts shown in the consolidated statements of cash flows is as follows:

	June 30,		December 31,
	2020		2019
	(In thousands)
Cash	$	618	$	913
Restricted cash		50		50
Total cash and restricted cash as shown in the consolidated statements of cash flows	$	668	$	963

Recently Adopted Accounting Pronouncements

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework – Changes to the Disclosure Requirement for Fair Value Measurement. This ASU removes, modifies and adds certain disclosure requirements of ASC Topic 820. The Company adopted this ASU effective January 1, 2020 as required and its adoption did not have a material impact on the Company’s consolidated financial statements for the reporting period.

Other 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 consolidated financial statements upon adoption. 

3. Capital Stock 

During the six months ended June 30, 2020, the Company issued a total of 151,027 shares of its common stock at a purchase price of $3.70 per share and warrants to purchase 151,027 shares of common stock at an exercise price of $3.70 per share to a group of investors for aggregate gross and net proceeds of approximately $0.6 million, of which $0.5 million and $0.1 million was allocated to the common stock and warrants, respectively. The Company classified these warrants on its consolidated balance sheets as equity as the warrants do not have any redemption features nor a right to put for cash that is outside the control of the Company, and valued using the Black-Scholes model based on the following weighted average assumptions:

Risk-free interest rate		0.88	%
Expected volatility		106.7	%
Expected term		2	months
Expected dividend yield		-
Exercise price	$	3.70
Market value of common stock	$	3.11

During the six months ended June 30, 2020, the Company issued 141,533 shares of its common stock to a group of investors in connection with the exercise of 141,533 previously issued warrants at $3.70 per share for aggregate gross and net proceeds of approximately $0.5 million.

During the six months ended June 30, 2020, the Company issued 214,000 shares of its common stock to a group of investors in connection with the exercise of 214,000 previously issued warrants at $2.00 per share for aggregate gross and net proceeds of approximately $0.4 million.

During the six months ended June 30, 2020, the Company issued a total of 25,948 shares of its common stock to employees due to the vesting of restricted stock units and issuance of a common stock award.

10

Warrant to purchase common stock activity for the six months ended June 30, 2020 was as follows:

	Amount			Weighted-Average Exercise Price
Outstanding at December 31, 2019		2,673,051		$	5.38
Issued		151,027			3.70
Exercised		(355,553	)		2.68
Outstanding at June 30, 2020		2,468,525		$	5.66

4. Notes Payable

On May 4, 2020, the Company obtained a loan (Loan) from the Bank of America (Lender) in the aggregate amount of $404,221, pursuant to the PPP, established as part of the CARES Act. The Loan is evidenced by a promissory note dated May 4, 2020 issued by the Company and will accrue interest at a fixed interest rate of 1% per annum from the funding date of May 4, 2020. Payments of principal and interest are deferred for the first six months following funding under the original terms of the promissory note.

Under the terms of the PPP, certain amounts of the Loan may be forgiven if they are used for qualifying expenses as described in the CARES Act. The terms of the promissory note, including eligibility and forgiveness, may be subject to additional requirements adopted by the SBA. Any unforgiven portion of the PPP loan, including principal and interest, will mature on May 4, 2022 and will be payable monthly commencing on November 4, 2020. The Note may be prepaid by the Company at any time prior to maturity with no prepayment penalties.

On June 5, 2020, the PPP Flexibility Act was signed into law, providing companies with the option to extend the loan forgiveness period from 8 weeks to 24 weeks after loan origination, a reduction of the required amount of payroll expenditures from 75% to 60%, and the removal of payroll tax deferrals upon loan forgiveness. The PPP Flexibility Act also provides the lender the right to extend the maturity date of the promissory note from two years to five years.

The Company has recorded the borrowings under the Loan in the accompanying balance sheet based on the terms of the Loan, using a two-year repayment schedule, commencing November 4, 2020. In the event the Loan is amended to provide for a five year repayment schedule or certain of the amounts are forgiven, each of which are at the sole discretion of the Lender, the Company will account for the change in terms in the period in which the events occur. There is no assurance that the term of the Loan will be extended or any portion of the Loan will be forgiven.

The Company has accounted for the loan under FASB ASC 470, Debt. Repayment amounts due within 1 year have been recorded as current liabilities, and the remaining amounts due in more than 1 year as long-term liabilities. If the Company is successful in receiving forgiveness for any portion of the loan used for qualifying expenses, those amounts will be recorded as a gain upon extinguishment.

5. Fair Value Measurements

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 as of June 30, 2020 and December 31, 2019. The Company’s restricted cash that serves as collateral for the Company’s credit card program is held in a demand money market account and is measured at fair value based on quoted prices, which are Level 1 inputs. The Company classifies warrants to purchase common stock that are accounted for as liabilities as Level 3 liabilities, as discussed below.

The Company's notes payable carrying value at June 30, 2020 approximates fair value due to the relatively small amount of principal and the short duration of the note payable. The Company had no notes payable at December 31, 2019. See Note 4.

6.  Share-Based Compensation

Biostage 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.

In June 2020, the Company’s shareholders approved the Amended and Restated Equity Incentive Plan, to among other things, increase of the number of shares of the Company’s common stock available for issuance pursuant to the 2013 Equity Incentive Plan by 3,000,000 shares, which increased the total shares authorized to be issued under the Plan to 5,098,000. There are 3,329,430 shares available for issuance as of June 30, 2020.

The Company has granted options to purchase common stock and restricted stock units (RSUs) under the Plan. Stock option and restricted stock unit activity during the six months ended June 30, 2020 was as follows:

	Stock Options					Restricted Stock Units
	Amount			Weighted – Average Exercise Price		Amount			Weighted – Average Grant Date Fair Value
Outstanding at December 31, 2019		1,772,761		$	6.04		3,300		$	7.68
Granted		275,337			2.87		-			-
Vested (RSUs)		-			-		(3,300	)		7.68
Canceled		(343,377	)		2.70		-			-
Outstanding at June 30, 2020		1,704,721		$	6.20		-		$	-

The Company’s outstanding stock options include 338,663 performance-based awards that have vesting provisions subject to the achievement of certain business milestones. In September 2019, the Company deemed the achievement of one of the performance-based milestones totaling 95,131 shares probable for accounting purposes, are now exercisable, and recognized approximately $0.3 million of expense associated with this milestone during the year ended December 31, 2019. Total unrecognized compensation expense for the remaining 243,532 performance-based awards is approximately $0.8 million. No expense has been recognized for these unvested awards as of June 30, 2020 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 for the year ended June 30, 2020 was approximately $43,000 based on the Company’s closing stock price of $2.51 per share as of June 30, 2020. As of June 30, 2020, unrecognized compensation cost related to unvested nonperformance-based awards amounted to $0.8 million, which will be recognized over a weighted average period of 0.8 years.

The Company uses the Black-Scholes option pricing model to value its stock options. The weighted average assumptions for valuing options granted during the six months ended June 30, 2020 were as follows: 

Risk-free interest rate	0.71	%
Expected volatility	109.7	%
Expected term	4.2	years
Expected dividend yield	n/a

In February 2020, as part of the termination arrangement with the Company’s former chief executive officer, the Company modified certain options to purchase 236,970 shares of common stock, issued an 80,000 fully vested stock option grant, and accelerated the vesting of 3,300 restricted stock units resulting in recording $153,000, $70,000, and $4,000, respectively, of share-based compensation.

13

In March 2020, the Company issued 35,000 common stock awards to an employee to be earned upon the achievement of certain milestones. Such milestones were achieved as of June 30, 2020 and the Company issued 23,793 fully vested share of common stock to the employee with 11,207 common shares withheld to cover taxes. The Company recognized share-based compensation of $65,200 and $140,000 for the three and six months ended June 30, 2020, respectively.

The Company recorded share-based compensation expense in the following expense categories of its consolidated statements of operations:

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
	(In thousands)				(In thousands)
Research and development	$	69	$	81	$	161	$	153
General and administrative		196		450		692		671
Total share-based compensation	$	265	$	531	$	853	$	824

The Company estimates the fair value of non-employee share options using the Black-Scholes option pricing model reflecting the same assumptions as applied to employee and director options in each of the reporting periods, other than the expected life, which is assumed to be the remaining contractual life of the options.

7.  Commitments and Contingencies

First Pecos Breach Notice

In June 2017, the Company entered into a binding Memorandum of Understanding with First Pecos, LLC (First Pecos), pursuant to which the Company agreed to issue to First Pecos in a private placement 485,000 shares of its common stock on a post-reverse split basis at a purchase price of $6.30 per share or, to the extent First Pecos, following the transaction, would own more than 19.9% of the Company’s common stock, shares of a new class of preferred stock of the Company with a per-share purchase price of $1,000.

In October 2017, as a result of the First Pecos failure to deliver the Purchase Price to the Company following satisfaction of all closing conditions in the Purchase Agreement, the Company delivered a notice to First Pecos and its manager, Leon “Chip” Greenblatt III, stating that First Pecos was in breach of the Purchase Agreement. None of the shares of common stock, shares of preferred stock or warrants were issued to First Pecos. Also in October 2017, First Pecos delivered a notice to the Company stating that, as a result of alleged breaches by the Company of its obligations pursuant to the Purchase Agreement, First Pecos terminated the Purchase Agreement and demanded that the Company pay a $500,000 termination fee pursuant to the terms of the Purchase Agreement.

The Company believes that it was not in breach of the Purchase Agreement at any time, and that the First Pecos notice was unjustified and without any legal merit or factual basis. Accordingly, the Company believes that First Pecos was not entitled to terminate the Purchase Agreement, and was not entitled to any termination fee thereunder, as the failure to consummate the Pecos Placement resulted from the First Pecos breach of the Purchase Agreement. The Company has not accrued for this liability as the Company believes the claim to be without merit.

Other

On April 14, 2017, representatives for the estate of a deceased individual filed a civil lawsuit in the Suffolk Superior Court, in Boston, Massachusetts, against the Company and Harvard Bioscience. The complaint alleges that the decedent’s injury and death were caused by two tracheal implants that incorporated synthetic trachea scaffolds and a biologic component combined by the implanting surgeon with a bioreactor, and surgically implanted in the decedent in two surgeries performed in 2012 and 2013. The civil complaint seeks a non-specific sum of money to compensate the plaintiffs. This civil lawsuit relates to the Company’s first-generation trachea scaffold technology for which the Company discontinued development in 2014, and not to the Company’s current Cellspan technology nor to its lead development product candidate, the Cellspan Esophageal Implant. The Company intends to vigorously defend this case. While the Company believes that such claim lacks merit, the Company is unable to predict the ultimate outcome of such litigation. In accordance with a separation and distribution agreement between Harvard Bioscience and the Company relating to the spin-off, the Company would be required to indemnify Harvard Bioscience against losses that Harvard Bioscience may suffer as a result of this litigation. The Company has been informed by its insurance provider that the case has been accepted as an insurable claim under the Company’s product liability insurance policy. The Company does not believe a loss is probable at this time and therefore has not accrued any amounts for this contingent liability.

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.

8. Leases

The Company leases laboratory and office space and certain equipment with remaining terms ranging approximately from 1 year to 4.5 years.

The laboratory and office space arrangement is under a sublease that was renewed in December of 2019 and currently extends through May 31, 2021. This lease automatically renews annually for a one-year period unless the Company or the counterparty provides a notice of termination within one hundred and eighty days prior to May 31 of each year.

All of the Company’s leases qualify as operating leases. The following table summarizes the presentation of the Company’s operating leases in its consolidated balance sheets:

(In thousands)	Balance Sheet Classification	At June 30, 2020
Assets:
Operating lease assets	Right-of-use asset	$	141
Liabilities:
Current operating lease liabilities	Current portion of operating lease liabilities	$	100
Non-current operating lease liabilities	Operating lease liabilities, net of current portion		41
Total operating lease liabilities		$	141

The Company recorded operating lease expense in the following categories in its consolidated statements of operations:

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
	(In thousands)				(In thousands)
Research and development	$	19	$	18	$	22	$	36
General and administrative		11		10		39		20
Total operating lease expense	$	30	$	28	$	61	$	56

The minimum lease payments for the next five years are expected to be as follows:

(In thousands)	As Of June 30, 2020
2020	$	61
2021		62
2022		19
2023		12
2024		7
Total lease payments	$	161
Less: imputed interest		20
Present value of operating lease liabilities	$	141

Cash paid included in the computation of the right of use asset and lease liability during the six months ended June 30, 2020 and 2019 amounted to approximately $61,000 and $56,000, respectively.

15

The weighted average remaining lease term and weighted average discount rate of the Company’s operating leases are as follows:

	As Of June 30, 2020
Weighted average remaining lease term (in years)		2.07
Weighted average discount rate		13.13	%

9. Net Loss Per Share

The following potential common shares were excluded from the calculation of diluted net loss per share attributable to common stockholders for the six months ended June 30, 2020 and 2019 because including them would have had an anti-dilutive effect:

	Six Months Ended June 30,
	2020		2019
Warrants to purchase common stock		2,468,525		3,523,821
Options to purchase common stock		1,704,721		1,627,811
Unvested restricted common stock units		-		3,300
Total		4,173,246		5,154,932

10. Income Taxes

The Company did not provide for any income taxes in its consolidated statements of operations for the three and six months ended June 30, 2020 and 2019. The Company has provided a valuation allowance for the full amount of its net deferred tax assets because, at June 30, 2020 and December 31, 2019, it was more likely than not that any future benefit from deductible temporary differences and net operating loss and tax credit carryforwards would not be realized.

The Company has not recorded any amounts for unrecognized tax benefits as of June 30, 2020 or December 31, 2019. As of June 30, 2020 and December 31, 2019, the Company had no accrued interest or tax penalties recorded related to income taxes. The Company is subject to U.S. federal income tax and Massachusetts state income tax. The statute of limitations for assessment by the IRS and state tax authorities is open for all periods from inception through December 31, 2018; currently, no federal or state income tax returns are under examination by the respective taxing authorities.

Under the provisions of the Internal Revenue Code, the net operating loss and tax credit carryforwards are subject to review and possible adjustment by the IRS and state tax authorities. Net operating loss and tax credit carryforwards may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant shareholders over a three-year period in excess of 50 percent, as defined under Sections 382 and 383 of the Internal Revenue Code, respectively, as well as similar state provisions. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value of the Company immediately prior to the ownership change. Subsequent ownership changes may further affect the limitation in future years. The Company has recently completed several equity financing transactions which have either individually or cumulatively resulted in a change in control as defined by Sections 382 and 383 of the Internal Revenue Code, or could result in a change in control in the future. The Company does not believe the impact of any limitation on the use of its net operating loss or credit carryforwards will have a material impact on the Company’s consolidated financial statements since the Company has a full valuation allowance against its deferred tax assets due to the uncertainty regarding future taxable income for the foreseeable future.

For all periods through June 30, 2020, the Company generated research credits but has not conducted a study to document the qualified activities. This study may result in an adjustment to the Company’s research and development credit carryforwards; however, until a study is completed and any adjustment is known, no amounts are being presented as an uncertain tax position. A full valuation allowance has been provided against the Company’s research and development credits and, if an adjustment is required, this adjustment would be offset by an adjustment to the deferred tax asset established for the research and development credit carryforwards and the valuation allowance.

Coronavirus Aid, Relief and Economic Security Act

In response to the COVID-19 pandemic, the CARES Act was signed into law in March 2020. The CARES Act lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (2017 Tax Act). Corporate taxpayers may carryback federal and state net operating losses (NOLs) originating during 2018 through 2020 for up to five years, which was not previously allowed under the 2017 Tax Act. The CARES Act also eliminates the 80% of taxable income limitations by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018, 2019 or 2020. Taxpayers may generally deduct interest up to the sum of 50% of adjusted taxable income plus business interest income (30% limit under the 2017 Tax Act) for tax years beginning January 1, 2019 and 2020. The CARES Act allows taxpayers with alternative minimum tax credits to claim a refund in 2020 for the entire amount of the credits instead of recovering the credits through refunds over a period of years, as originally enacted by the 2017 Tax Act.

In addition, the CARES Act raises the corporate charitable deduction limit to 25% of taxable income and makes qualified improvement property generally eligible for 15-year cost-recovery and 100% bonus depreciation. The enactment of the CARES Act did not result in any material adjustments to the Company’s income tax provision for the three and six months ended June 30, 2020, or to the Company’s net deferred tax assets as of June 30, 2020.

11. Subsequent Events

Equity Transactions

Subsequent to end of the quarter ended June 30, 2020, the Company issued 58,932 shares of its common stock to a group of investors in connection with the exercise of 58,932 previously issued warrants at $3.70 per share for aggregate gross and net proceeds of approximately $0.2 million. See Note 1.

SBIR Award

On August 3, 2020, the Company was awarded the second year of a Phase II Fast-Track SBIR grant from the Eunice Kennedy NICHD totaling $0.5 million for support of development, testing, and translation to the clinic covering qualified expenses incurred from October 1, 2019 through September 30, 2020. The Company is evaluating the impact of this grant award. See Note 2.

The Company has performed an evaluation of subsequent events through the time of filing this Quarterly Report on Form 10-Q with the Securities Exchange Commission and has determined that there are no such events to report other than those disclosed above.

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.

Biostage, Inc. is referred to herein as “we,” “our,” “us,” and “the Company”.

Business Overview

We are a clinical-stage biotechnology company developing bioengineered organ implants based on our novel technology. The foundation of our Cellframe^TM technology is a proprietary biocompatible scaffold that is seeded with the recipient’s own mesenchymal stromal cells to form our Cellspan^TM implant. Our technology combines the clinically proven principles of tissue engineering, cell biology and materials science. This technology is being developed to treat life-threatening conditions of the esophagus, trachea and bronchus with the objective of dramatically improving the treatment paradigm for those patients.

We believe our technology will provide surgeons with new ways to address damage to the esophagus, bronchus, and trachea due to congenital abnormalities, diseases, infections and traumas. Products being developed based on our technology for those indications are called Cellspan products.

The Cellspan Esophageal Implant (CEI) product candidate is our lead development product candidate. We are pursuing two development programs that address conditions of the esophagus: esophageal atresia (EA) in pediatric patients and esophageal disease in adult patients. Our Cellspan esophageal product candidates are each intended to provide a surgical solution to stimulate regeneration of a segment of the esophagus missing due to a congenital abnormality or following surgical removal to establish or reestablish the organ’s continuity and integrity.

We believe that a pediatric CEI may provide pediatric surgeons with a better procedure to treat EA that would result in a connected esophagus with higher success rates, lower complications and lower overall costs to the healthcare system. Approximately one in 4,000 infants in the U.S. is born with esophageal atresia, a congenital condition where the child’s esophagus is underdeveloped and does not extend completely from the mouth to the stomach. When a long segment of the esophagus is lacking, the current standard of care is a series of surgical procedures where surgical sutures are applied to both ends of the esophagus in an attempt to stretch them together so they can be connected at a later date. This process can take weeks and the procedure can result in serious complications and may carry high rates of failure. Such approach also requires, in time, at least two separate surgical interventions. Other options include the use of the child’s stomach that would be pulled up, or a piece of the patient’s intestine that would be moved to the gap, to allow a connection to the mouth. We are working to develop a CEI product candidate to address newborns’ EA, which we expect to provide a simpler, more effective and potentially organ-sparing solution.

18

A portion of all patients diagnosed with esophageal cancer are treated via a surgical procedure known as an esophagectomy. The current standard of care for an esophagectomy requires a complex surgical procedure that involves moving the patient’s stomach or a portion of their colon into the chest to replace the portion of esophagus resected by the removal of the tumor. These current procedures have high rates of complications, can lead to a severely diminished quality of life, and require costly ongoing care. Our CEIs aim to simplify the procedure, reduce complications, result in a better quality of life and reduce the overall cost of these patients to the healthcare system.

In October 2019, we filed an Investigational New Drug (IND) application with the U.S Food and Drug Administration (FDA) to treat patients with esophageal disease, absent of cancer, in adults that would require a short segment esophageal implant following clinically indicated short segment resection of the thoracic esophagus with our CEI product candidate. In November 2019, we received notice from the FDA placing our IND on clinical hold and providing a preliminary list of clinical hold and non-clinical hold questions. In December 2019, we received the formal letter with clinical hold and non-clinical hold questions and submitted our response to the clinical hold questions on February 18, 2020. On March 19, 2020, the FDA notified us that the IND for our CEI product candidate has been removed from clinical hold and that we can proceed with our study. This FDA approval enables us to start clinical planning, engaging with a clinical research organization and site readiness in advance of starting the clinical trial for our CEI product candidate. On May 7, 2020, we submitted responses to certain non-clinical hold questions and expect to submit remaining non-clinical hold responses in Q3 2020, except for our clinical trial details once a clinical research organization is selected. The COVID-19 pandemic could adversely impact our business, including planned clinical trials, as discussed below in this Item.

We believe that receiving regulatory approval to treat pediatric EA with our CEI may provide a shorter time to a commercial product and the greater overall potential value in the U.S. market. In addition to providing a novel solution for what we believe is a great medical need, approval of our pediatric EA product candidate may result in receipt of a priority review voucher, which if achieved, in our opinion, could potentially provide significant value and non-dilutive funding to Biostage in the future. We have continued to advance our CEI pediatric esophagus program and plan to file a protocol amendment with the FDA to update our CEI esophageal disease clinical program after the initial adult patients are treated in the esophageal disease trial, subject to FDA approval.

Our products are currently in development and have not yet received regulatory approval for sale anywhere in the world.

Business Overview Update regarding COVID-19

On January 30, 2020, the World Health Organization declared the COVID-19 outbreak a “Public Health Emergency of International Concern” and on March 11, 2020, declared it a pandemic. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, expenses, clinical trial, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain it or treat COVID-19, as well as the economic impact that may impact us. Our employees have been working remotely since early March 2020, and we continue to conduct limited operations including administration functions and planning for our future Cellspan Esophageal Implant (CEI) clinical trial that was removed from clinical hold on March 19, 2020. While we are currently planning the clinical trial, we expect that COVID-19 precautions may directly or indirectly impact the timeline of the clinical trial. The global outbreak of the COVID-19 coronavirus continues to rapidly evolve. The extent to which the COVID-19 coronavirus may impact our business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the duration of the outbreak, travel restrictions and social distancing in the U.S. and other countries, business closures or business disruptions and the effectiveness of actions taken in the U.S. and other countries to contain and treat the disease.

Financial Condition and Need for Additional Funds

We expect to continue to incur operating losses and negative cash flows from operations for 2020 and in future years.

Operating Losses and Cash Requirements

We have incurred substantial operating losses since our inception, and as of June 30, 2020 had an accumulated deficit of approximately $67.3 million, which will require us to seek additional financing to fund future operations. We expect that our operating cash on-hand at June 30, 2020 of $0.6 million, along with net proceeds received subsequent to the end of the quarter of approximately $0.2 million from the issuance of 58,932 shares of our common stock from the exercise of 58,932 previously issued warrants at $3.70 per share will enable it to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2020. In addition, in May 2020 we received $404,221 of loan proceeds as part of the Paycheck Protection Program (PPP), established as part of the Coronavirus Aid, Relief, and Economic Security (CARES) Act. Based on the current loan terms, payments begin in November 2020 subject to us meeting the partial or full loan forgiveness requirements (See Note 4 in the Consolidated Financial Statements included in Part I “Financial Information”, Item 1 of this report for further discussion). As discussed in Note 1 to the consolidated financial statements, these conditions raise substantial doubt about our ability to continue as a going concern.

We are currently investing significant resources in development of products for use by clinicians in the field of regenerative medicine. We will need to raise additional funds in future periods to fund our operations. In the event that we do not raise additional capital from outside sources, we may be forced to further curtail or cease our operations. Cash requirements and cash resource needs will vary significantly depending upon the timing of clinical and animal studies and other resource needs that will be required to complete ongoing development and pre-clinical and clinical testing of products, as well as related regulatory efforts and collaborative arrangements necessary for our product candidates that are currently under development. We are currently seeking and continue to seek financings from 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, or strategic collaborations and licensing arrangements. We may not be able to obtain additional financing on terms favorable to us, if at all.

Small Business Innovation Research Grant

On March 28, 2018, we were awarded a Fast-Track Small Business Innovation Research (SBIR) grant by the Eunice Kennedy National Institute of Child Health and Human Development (NICHD) to support testing of pediatric Cellspan™ Esophageal Implants (CEIs). The award for Phase I, which was earned over the nine months ended September 30, 2018, provided for the reimbursement for up to approximately $0.2 million of qualified research and development costs. 

On October 26, 2018, we were awarded Phase II of the SBIR grant totaling $1.1 million to support activities for development, testing, and translation to the clinic through September 2019. As of September 30, 2019, we had expended $0.6 million of the $1.1 million awarded, and in December 2019 submitted a modified Phase II grant development plan totaling $1.0 million, including $0.5 million of the unspent Phase 2 grant awarded and an additional $0.5 million for the next year of the project, subject to the NICHD approval. This modified development plan was approved by the NICHD on August 3, 2020. (See Note 11 in the Consolidated Financial Statements included in Part I “Financial Information”, Item 1 of this report for further discussion). The SBIR grant has the potential to provide a total award of approximately $1.8 million, of which approximately $0.8 million has been expended through June 30, 2020.

Grant income is recognized based on timing of when qualified research and development costs are incurred and recorded and classified as grant income in other income (expense), net in the consolidated statements of operations. We recognized $473,000 from Phase II during 2019 and $225,000 from Phase I and $176,000 from Phase II in 2018. There was no activity under the SBIR grant for the three and six months ended June 30, 2020.

Management and Employees

We disclosed in our Current Report on Form 8-K dated June 17, 2019 that Thomas McNaughton, our former Chief Financial Officer, resigned from his role effective June 14, 2019. We also disclosed in our Current Report on Form 8-K dated February 7, 2020 that James McGorry, our former Chief Executive Officer, resigned from his role effective February 7, 2020. We are currently in the process of evaluating our options to fill these positions. At June 30, 2020, we had 9 employees, of whom eight were full-time and one was part-time.

Results of Operations

Components of Operating Loss

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, autoseeders, and 3D bioreactors, 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.

Selling, general and administrative expense. Selling, general and administrative expense consists primarily of salaries and other related expenses, including share-based compensation, for personnel in executive, accounting, information technology and human resources roles. Other costs include professional fees for legal and accounting services, insurance, investor relations and facility costs.

Other Income (Expense)

Grant income. Grant income reflects income earned under the SBIR grant. Grant income is recognized based on timing of when qualified research and development costs are incurred.

21

Changes in fair value of warrant liability. Changes in fair value of warrant liability represent the change in the fair value of common stock warrants classified as liability awards during the three and six months ended June 30, 2020 and 2019. We use the Black-Scholes pricing model to value the related warrant liability. The costs associated with the issuance of the warrants have been recorded as an expense upon issuance.

The following table summarizes the results of our operations for the three and six months ended June 30, 2020 and 2019 ($ in thousands):

Comparison of the three months ended June 30, 2020 compared to the three months ended June 30, 2019

Research and Development Expense

Research and development expense decreased approximately 61% to $0.5 million for the three months ended June 30, 2020 compared to $1.4 million for the three months ended June 30, 2019. This decrease was due primarily to $0.5 million of lower outsourced study costs and lab operating supplies, a $0.2 million decrease in regulatory consulting expenses, $0.1 million of lower employee expenses, and a $0.1 decrease in all other expenses.

Based on the removal of our IND from clinical hold by the FDA on March 19, 2020, we expect our research and development costs will increase significantly when we start clinical trial activities to the extent that we have funds available. Due to the impact of COVID-19 on operations, the start of our clinical trial is dependent on planning activities in addition to site availability to commence a clinical trial for our product.

Selling, General and Administrative Expense

Selling, general and administrative expense decreased approximately 44% to $0.7 million for the three months ended June 30, 2020 compared to $1.3 million the same period in 2019. This decrease was due primarily to $0.4 million of lower employee based expenses due to reduced staff, and $0.2 million of lower share-based compensation due primarily to costs in the prior year period associated with the separation arrangement with our former chief financial officer.

Grant income

There was no grant income for qualified expenditures from an SBIR grant for the three-month period ended June 30, 2020 as the modified Phase II grant development plan we submitted to the NICHD has not yet been approved as of June 30, 2020. For the three months ended June 30, 2019 we recorded grant income of $223,000 for qualified expenditures under the SBIR grant.

22

Change in fair value of warrant liability

During the three months ended June 30, 2020, the change in fair value of our warrant liability resulted in other income of $78,000 due primarily to a lower stock price of the underlying common shares. This compared to $16,000 of other income for three months ended June 30, 2019 due to a decrease in the price of the underlying common shares. The other income in both periods was partly offset by an increase in the volatility of the underlying common shares.

Comparison of the six months ended June 30, 2020 to the six months ended June 30, 2019

Research and Development Expense

Research and development expense decreased approximately 51% to $1.2 million for the six months ended June 30, 2020 compared to $2.4 million for the comparable six-month period in 2019. This decrease was due primarily to $0.6 million of lower outsourced study costs and lab operating supplies, a $0.3 million decrease in regulatory consulting expenses, $0.2 million of lower employee expenses, and a $0.1 decrease in all other expenses.

Selling, General and Administrative Expense

Selling, general and administrative expense decreased approximately 14% to $2.0 million compared to $2.3 million for the same period in 2019. This decrease was due primarily to $0.4 million of lower employee-based expenses due to the separation of our former chief executive officer and chief financial officer, offset in part by a $0.1 million increase in all other expenses.

Grant income

There was no grant income for qualified expenditures from an SBIR grant for the six-month period ended June 30, 2020 as the modified Phase II grant development plan we submitted to the NICHD has not yet been approved as of June 30, 2020. For the six months ended June 30, 2019 we recorded grant income of $337,000 for qualified expenditures under the SBIR grant.

Change in fair value of warrant liability

During the six months ended June 30, 2020, the change in fair value of our warrant liability resulted in other expense of $22,000 due primarily to a higher stock price and volatility of the underlying common shares. This compared to other income of $9,000 for six months ended June 30, 2019 due primarily to a decrease in the remaining expected term of the underlying common shares during the six months ended June 30, 2019, offset in part by an increase in the price and volatility of the underlying common shares.

Liquidity and Capital Resources

Sources of liquidity.  We have incurred operating losses since inception, and as of June 30, 2020 we had an accumulated deficit of approximately $67.3 million. We are currently investing significant resources in the development and commercialization of our products 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.

The following table sets forth the primary uses of cash for the six months ended June 30, 2020 (in thousands):

	Six Months Ended June 30,
	2020			2019
Net Cash Used in Operating Activities	$	(2,165	)	$	(3,253	)
Net Cash Used by Investing Activities	$	-		$	(78	)
Net Cash Provided by Financing Activities	$	1,870		$	3,277

Comparison of Six Months Ended June 30, 2020 and 2019

Operating activities.  Net cash used in operating activities of $2.2 million for the six months ended June 30, 2020 was due primarily to our net loss of $3.2 million, partially offset by $1.0 million add-back for non-cash expenses including share-based compensation, depreciation, change in fair value of warrant liability, and amortization of right-of-use assets. The cash impact of working capital due to the timing of prepaid expenses and accounts payable was negligible during the period.

Net cash used in operating activities of $3.3 million for the six months ended June 30, 2019 was primarily due primarily to our net loss of $4.4 million, partially offset by $0.9 million non-cash expenses related to share-based compensation, depreciation, change in fair value of warrant liability, and amortization of right-of-use assets, and $0.2 million of cash provided from working capital due to the timing of accounts payable and prepaid expenses.

23

Investing activities.  There were no investing activities for the six months ended June 30, 2020. Net cash used for investing activities for the six months ended June 30, 2019 reflected $78,000 of equipment purchases.

Financing activities. Net cash generated from financing activities during the six months ended June 30, 2020 of $1.9 million consisted of $0.6 million of net proceeds received from private placement transactions that resulted in the issuance of 151,027 shares of our common stock and warrants to purchase 151,027 shares of common stock to a group of investors at an exercise price of $3.70 per share, $1.0 million received from the issuance of 355,553 shares of our common stock to a group of investors in connection with previously issued warrants, and $0.4 million from a loan granted to us in May 2020 pursuant to the PPP established as part of the CARES Act. These proceeds were offset slightly by $46,000 of payments for employee tax withholdings for common shares repurchased for vested stock awards.

Net cash generated from financing activities of $3.3 million during the six months ended June 30, 2019 consisted of $1.3 million of net proceeds received from private placement transactions that resulted in the issuance of 345,174 shares of our common stock and warrants to purchase 345,174 shares of common stock to a group of investors at an exercise price of $3.70 per share, and $2.0 million received from the issuance of 1,000,000 shares of our common stock to a group of investors in connection with previously issued warrants.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which we have prepared in accordance with accounting principles generally accepted in the United States, or. GAAP. The preparation of these consolidated 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 consolidated 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 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.

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. 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 these models. 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 warrant are recognized as a component of other income (expense) in the condensed consolidated statements of operations. We will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrant.

24

Off-Balance Sheet Arrangements

We do not have any material off-balance sheet arrangements as of June 30, 2020.

Other Information

JOBS Act

On April 5, 2012, the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act, for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.

We have evaluated the benefits of relying on other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, as an “emerging growth company,” we rely on certain of these exemptions, including without limitation, (i) providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (ii) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board (PCAOB) regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the consolidated financial statements, known as the auditor discussion and analysis. We will remain an “emerging growth company” until the earliest of (a) the last day of the fiscal year in which we have total annual gross revenues of $1 billion or more, (b) the last day of our fiscal year following the fifth anniversary of the date of the completion of our initial public offering, or December 31, 2020, (c) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years or (d) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

The Company is a smaller reporting company and is not required to provide this information pursuant to Item 305(e), Regulation S-K.

Item 4. Controls and Procedures.

This report includes the certifications of our President (who is our principal executive officer) and our Vice President of Finance (who is our principal financial and accounting officer) required by Rule 13a-14 of the Exchange Act. See Exhibits 31.1 and 31.2. This Item 4 includes information concerning the controls and control evaluations referred to in those certifications

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including the President and Vice President of Finance, to allow timely decisions regarding required disclosures.

In connection with the preparation of this Quarterly Report on Form 10-Q, our management, under the supervision and with the participation of our President and Vice President of Finance, conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of June 30, 2020. Based upon the evaluation described above, our President and Vice President of Finance have concluded that they believe our disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report on Form 10-Q.

Changes in Internal Control over Financial Reporting

Our management, with the participation of the President and Vice President of Finance, has evaluated whether any change in our internal control over financial accounting and reporting occurred during the quarter ended June 30, 2020. During the period covered by this report, we have concluded that there were no changes during the fiscal quarter in our internal control over financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act, which have materially affected, or are reasonably likely to materially affect, our internal control over financial accounting and reporting. 

25

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be involved in various claims and legal proceedings arising in the ordinary course of business. 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 27, 2020, 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.

Item 1A. Risk Factors

To our knowledge and except to the extent additional factual information disclosed in this Quarterly Report on Form 10-Q relates to such risk factors, and the additional risk factor noted below, there have been no material changes in the risk factors described in Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2019, which was filed with the SEC on March 27, 2020.

Financial Position, Need for Capital and Operating Risks - All or a portion of the PPP Loan may not be forgivable and our application for the PPP Loan could in the future be determined to have been impermissible which could adversely impact our business and reputation.

On May 4, 2020, we obtained a loan (Loan) from the Bank of America (Lender) in the aggregate amount of $404,221, pursuant to the Paycheck Protection Program (PPP), established as part of the Coronavirus Aid, Relief and Economic Security Act (CARES Act). Our application for the PPP Loan could in the future be determined to have been impermissible which could adversely impact our business and reputation. Under the CARES Act, we may be eligible to apply for forgiveness of all loan proceeds used to pay payroll costs, rent, utilities and other qualifying expenses, provided that we retain a certain number of employees and maintain compensation within certain regulatory parameters of the PPP. However, we cannot provide any assurance that we will be eligible for loan forgiveness or that any amount of the PPP Loan will ultimately be forgiven.

In applying for the PPP Loan, we were required to certify, among other things, that the then current economic uncertainty made the PPP Loan necessary to support our ongoing operations. We made these certifications in good faith after analyzing, among other things, the requirements of the PPP loan, our current business activity and our ability to access other sources of liquidity sufficient to support our ongoing operations in a manner that would not be significantly detrimental to our business. We believe that we satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan was consistent with the broad objectives of the PPP of the CARES Act. The certification regarding necessity described above did not at the time contain any objective criteria and continues to be subject to interpretation. If, despite our good-faith belief that we satisfied all eligibility requirements for the PPP Loan, we are later determined to have violated any of the laws or governmental regulations that apply to us in connection with the PPP Loan, or it is otherwise determined that we were ineligible to receive the PPP Loan, we may be subject to civil, criminal and administrative penalties. Any violations or alleged violations may result in adverse publicity and damage to our reputation, a review or audit by the SBA or other government entity, or claims under the False Claims Act. These events could consume significant financial and management resources and could have a material adverse effect on our business, results of operations and financial condition.

Overview and Basis of Presentation

Overview and Basis of Presentation

1.  Overview and Basis of Presentation

Overview

Biostage, Inc. (Biostage or the Company) is a clinical-stage biotechnology company developing bioengineered organ implants based on the Company’s novel CellspanTM technology. The Company’s Cellspan technology is comprised of a biocompatible scaffold that is seeded with the recipient’s own stem cells. The Company believes that this technology may prove to be effective for treating patients across a number of life-threatening medical indications who currently have unmet medical needs. The Company is currently developing its Cellspan technology to treat life-threatening conditions of the esophagus, bronchus and trachea with the objective of dramatically improving the treatment paradigm for those patients. 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 one business segment and does not have significant costs or assets outside the United States.

On October 31, 2013, Harvard Bioscience, Inc. (Harvard Bioscience) contributed its regenerative medicine business assets, plus $15 million of cash, into Biostage (formerly “Harvard Apparatus Regenerative Technologies”) in a spin-off transaction. 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 of all the shares of common stock of Biostage to stockholders of Harvard Bioscience (the “HBIO Distribution”).

The Company’s common stock is currently traded on the OTCQB Venture Market under the symbol “BSTG”.

Basis of Presentation

The 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 (GAAP).

Use of Estimates

The preparation of the Company's consolidated financial statements requires the Company to make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities, equity, expenses and related disclosures. On an ongoing basis the Company evaluates its estimates, judgments and methodologies. The Company bases its estimates on historical experience and on various other assumptions that the Company believes are reasonable, the results of which form the basis for making judgments about the carrying values of assets, liabilities and equity and the amount of expenses. Actual results may differ from these estimates.

Going Concern

The Company has incurred substantial operating losses since its inception, and future losses are anticipated. As of June 30, 2020, the Company  has an accumulated deficit of approximately $67.3 million and will require additional financing to fund future operations. The Company expects that its operating cash on-hand at June 30, 2020 of $0.6 million, along with net proceeds received subsequent to the end of the quarter of approximately $0.2 million from the issuance of 58,932 shares of its common stock from the exercise of 58,932 previously issued warrants at $3.70 per share will enable it to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2020. In addition, on January 30, 2020 the World Health Organization declared the COVID-19 outbreak a "Public Health Emergency of International Concern" and on March 11, 2020, declared it a pandemic. The full extent to which the COVID-19 pandemic may directly or indirectly impact our business, results of operations and financial condition, expenses, clinical trial, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain it or treat COVID-19, as well as the economic impact that may impact the Company. Therefore, these conditions have caused management to determine there is substantial doubt 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 does not raise additional capital from outside sources before the fourth quarter of 2020, 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 pre-clinical and clinical testing of products, research and development, and regulatory efforts and collaborative arrangements necessary for the Company’s products that are currently under development. In addition, the Company received $404,221 of loan proceeds in May 2020 as part of the Paycheck Protection Program (PPP), established as part of the Coronavirus Aid, Relief, and Economic Security (CARES) Act. Based on the current loan terms, payments begin in November 2020 subject to the Company meeting the partial or full loan forgiveness requirements. See Note 4. The Company is 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. 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 such circumstance may materially affect the Company’s ability to continue as a going concern. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern and therefore, the 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.

Net Loss Per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the sum of the weighted average number of common shares outstanding during the period and, if dilutive, the weighted average number of potential shares of common stock, including the assumed exercise of stock options, warrants, and the impact of unvested restricted stock.

The Company applies the two-class method to calculate basic and diluted net loss per share attributable to common stockholders as its warrants to purchase common stock are participating securities.

The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. However, the two-class method does not impact the net loss per share of common stock as the Company has been in a net loss position and the warrant holders do not participate in losses.

Basic and diluted shares outstanding are the same for each period presented as all common stock equivalents would be antidilutive due to the net losses incurred.

Unaudited Interim Financial Information

The accompanying interim consolidated balance sheet as of June 30, 2020, consolidated interim statements of operations and stockholders’ equity for the three and six months ended June 30, 2020 and 2019, and consolidated statements of cash flows for the six months ended June 30, 2020 and 2019 are unaudited. The interim unaudited 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 June 30, 2020, its consolidated results of operations and consolidated stockholders’ equity for the three and six month periods ended June 30, 2020 and 2019 and consolidated statements of cash flows for the six month periods ended June 30, 2020 and 2019. The financial data and other information disclosed in these notes related to the three and six-month periods ended June 30, 2020 and 2019 are unaudited. The results for the three and six months ended June 30, 2020 are not necessarily indicative of results to be expected for the year ending December 31, 2020, any other interim periods or any future year or period.

Summary of Significant Accounting Policies and Recently Issued Accounting Pronouncements

2.  Summary of Significant Accounting Policies and Recently Issued Accounting Pronouncements

Summary of Significant Accounting Policies

The accounting policies underlying the accompanying unaudited consolidated financial statements are those set forth in Note 2 to the consolidated financial statements for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10‑K.

SBIR Award

On March 28, 2018, the Company was awarded a Fast-Track Small Business Innovation Research (SBIR) grant by the Eunice Kennedy National Institute of Child Health and Human Development (NICHD) of the National Institutes of Health to support testing of pediatric Cellspan Esophageal Implants. The award for Phase I, which was earned over the nine months ended September 30, 2018, provided for the reimbursement for up to approximately  $0.2 million of qualified research and development costs.

On October 26, 2018, the Company was awarded Phase II of the SBIR grant totaling $1.1 million to support expenses for development, testing, and translation to the clinic through September 2019. As of September 30, 2019, the Company had expended $0.6 million of the $1.1 million awarded, and in December 2019 submitted a modified Phase II grant development plan totaling $1.0 million, including $0.5 million unspent from the Phase 2 grant awarded and an additional $0.5 million for the next year of the project, subject to the NICHD approval. This modified development plan was approved by the NICHD on August 3, 2020. See Note 11. The SBIR grant has the potential to provide a total award of approximately $1.8 million, of which approximately $0.8 million has been recognized to date. The Company did not recognize grant income from Phase II of the SBIR grant for the three and six months ended June 30, 2020.

Grant income is recognized when qualified research and development costs are incurred and recorded in other income (expense), net in the consolidated statements of operations. When evaluating grant revenue from the SBIR grant, the Company considered accounting requirements under the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 606, Revenue From Contracts With Customers. The Company concluded that ASC 606 did not apply as there is no exchange of goods or services or an exchange of intellectual property between the parties; therefore, the Company presents grant income in other income.

Restricted Cash

Restricted cash consists of $50,000 held as collateral for the Company’s credit card program as of June 30, 2020 and December 31, 2019. The Company’s consolidated statements of cash flows include restricted cash with cash when reconciling the beginning-of-period and end-of-period total amounts shown on such statements.

A reconciliation of the cash and restricted cash reported within the balance sheet that sum to the total of the same amounts shown in the consolidated statements of cash flows is as follows:

	June 30,		December 31,
	2020		2019
	(In thousands)
Cash	$	618	$	913
Restricted cash		50		50
Total cash and restricted cash as shown in the consolidated statements of cash flows	$	668	$	963

Recently Adopted Accounting Pronouncements

In August 2018, the FASB issued ASU 2018‑13, Fair Value Measurement (Topic 820), Disclosure Framework – Changes to the Disclosure Requirement for Fair Value Measurement. This ASU removes, modifies and adds certain disclosure requirements of ASC Topic 820. The Company adopted this ASU effective January 1, 2020 as required and its adoption did not have a material impact on the Company’s consolidated financial statements for the reporting period.

Other 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 consolidated financial statements upon adoption.

4.  Notes Payable

On May 4, 2020, the Company obtained a loan (Loan) from the Bank of America (Lender) in the aggregate amount of $404,221, pursuant to the PPP, established as part of the CARES Act. The Loan is evidenced by a promissory note dated May 4, 2020 issued by the Company and will accrue interest at a fixed interest rate of 1% per annum from the funding date of May 4, 2020. Payments of principal and interest are deferred for the first six months following funding under the original terms of the promissory note.

Under the terms of the PPP, certain amounts of the Loan may be forgiven if they are used for qualifying expenses as described in the CARES Act. The terms of the promissory note, including eligibility and forgiveness, may be subject to additional requirements adopted by the SBA. Any unforgiven portion of the PPP loan, including principal and interest, will mature on May 4, 2022 and will be payable monthly commencing on November 4, 2020. The Note may be prepaid by the Company at any time prior to maturity with no prepayment penalties.

On June 5, 2020, the PPP Flexibility Act was signed into law, providing companies with the option to extend the loan forgiveness period from 8 weeks to 24 weeks after loan origination, a reduction of the required amount of payroll expenditures from 75% to 60%, and the removal of payroll tax deferrals upon loan forgiveness. The PPP Flexibility Act also provides the lender the right to extend the maturity date of the promissory note from two years to five years.

The Company has recorded the borrowings under the Loan in the accompanying balance sheet based on the terms of the Loan, using a two-year repayment schedule, commencing November 4, 2020. In the event the Loan is amended to provide for a five year repayment schedule or certain of the amounts are forgiven, each of which are at the sole discretion of the Lender, the Company will account for the change in terms in the period in which the events occur. There is no assurance that the term of the Loan will be extended or any portion of the Loan will be forgiven.

The Company has accounted for the loan under FASB ASC 470, Debt. Repayment amounts due within 1 year have been recorded as current liabilities, and the remaining amounts due in more than 1 year as long-term liabilities. If the Company is successful in receiving forgiveness for any portion of the loan used for qualifying expenses, those amounts will be recorded as a gain upon extinguishment.

Fair Value Measurements

5.  Fair Value Measurements

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 as of June 30, 2020 and December 31, 2019. The Company’s restricted cash that serves as collateral for the Company’s credit card program is held in a demand money market account and is measured at fair value based on quoted prices, which are Level 1 inputs. The Company classifies warrants to purchase common stock that are accounted for as liabilities as Level 3 liabilities, as discussed below.

The Company's notes payable carrying value at June 30, 2020 approximates fair value due to the relatively small amount of principal and the short duration of the note payable. The Company had no notes payable at December 31, 2019. See Note 4.

The following fair value hierarchy table presents information about the Company’s financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2020:

Biostage 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. In June 2020, the Company's shareholders approved the Amended and Restated Equity Incentive Plan, to among other things, increase of the number of shares of the Company’s common stock available for issuance pursuant to the 2013 Equity Incentive Plan by 3,000,000 shares, which increased the total shares authorized to be issued under the Plan to 5,098,000. There are 3,329,430 shares available for issuance as of June 30, 2020.

The Company has granted options to purchase common stock and restricted stock units (RSUs) under the Plan. Stock option and restricted stock unit activity during the six months ended June 30, 2020 was as follows:

	Stock Options			Restricted Stock Units
					Weighted –
		Weighted –			Average
		Average			Grant Date
	Amount	Exercise Price		Amount	Fair Value
Outstanding at December 31, 2019	1,772,761	$	6.04	3,300	$	7.68

Canceled	(343,377)		2.70	—		—
Outstanding at June 30, 2020	1,704,721	$	6.20	—	$	—

The Company’s outstanding stock options include 338,663 performance-based awards that have vesting provisions subject to the achievement of certain business milestones. In September 2019, the Company deemed the achievement of one of the performance-based milestones totaling 95,131 shares probable for accounting purposes, are now exercisable, and recognized approximately $0.3 million of expense associated with this milestone during the year ended December 31, 2019. Total unrecognized compensation expense for the remaining 243,532 performance-based awards is approximately $0.8 million. No expense has been recognized for these unvested awards as of June 30, 2020 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 for the year ended June 30, 2020 was approximately $43,000 based on the Company’s closing stock price of $2.51 per share as of June 30, 2020. As of June 30, 2020, unrecognized compensation cost related to unvested nonperformance-based awards amounted to $0.8 million, which will be recognized over a weighted average period of 0.8 years.

The Company uses the Black-Scholes option pricing model to value its stock options. The weighted average assumptions for valuing options granted during the six months ended June 30, 2020 were as follows:

Risk-free interest rate	0.71	%
Expected volatility	109.7	%
Expected term	4.2	years
Expected dividend yield	n/a

In February 2020, as part of the termination arrangement with the Company’s former chief executive officer, the Company modified certain options to purchase 236,970 shares of common stock, issued an 80,000 fully vested stock option grant, and accelerated the vesting of 3,300 restricted stock units resulting in recording $153,000,  $70,000, and $4,000, respectively, of share-based compensation.

In March 2020, the Company issued 35,000 common stock awards to an employee to be earned upon the achievement of certain milestones. Such milestones were achieved as of June 30, 2020 and the Company issued 23,793 fully vested share of common stock to the employee with 11,207 common shares withheld to cover taxes. The Company recognized share-based compensation of $65,200 and $140,000 for the three and six months ended June 30, 2020, respectively.

The Company recorded share-based compensation expense in the following expense categories of its consolidated statements of operations:

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019

General and administrative		196		450		692		671
Total share-based compensation	$	265	$	531	$	853	$	824

The Company estimates the fair value of non-employee share options using the Black-Scholes option pricing model reflecting the same assumptions as applied to employee and director options in each of the reporting periods, other than the expected life, which is assumed to be the remaining contractual life of the options.

First Pecos Breach Notice

In June 2017, the Company entered into a binding Memorandum of Understanding with First Pecos, LLC (First Pecos), pursuant to which the Company agreed to issue to First Pecos in a private placement 485,000 shares of its common stock on a post-reverse split basis at a purchase price of $6.30 per share or, to the extent First Pecos, following the transaction, would own more than 19.9% of the Company’s common stock, shares of a new class of preferred stock of the Company with a per-share purchase price of $1,000.

In October 2017, as a result of the First Pecos failure to deliver the Purchase Price to the Company following satisfaction of all closing conditions in the Purchase Agreement, the Company delivered a notice to First Pecos and its manager, Leon “Chip” Greenblatt III, stating that First Pecos was in breach of the Purchase Agreement. None of the shares of common stock, shares of preferred stock or warrants were issued to First Pecos. Also in October 2017, First Pecos delivered a notice to the Company stating that, as a result of alleged breaches by the Company of its obligations pursuant to the Purchase Agreement, First Pecos terminated the Purchase Agreement and demanded that the Company pay a $500,000 termination fee pursuant to the terms of the Purchase Agreement.

The Company believes that it was not in breach of the Purchase Agreement at any time, and that the First Pecos notice was unjustified and without any legal merit or factual basis. Accordingly, the Company believes that First Pecos was not entitled to terminate the Purchase Agreement, and was not entitled to any termination fee thereunder, as the failure to consummate the Pecos Placement resulted from the First Pecos breach of the Purchase Agreement. The Company has not accrued for this liability as the Company believes the claim to be without merit.

Other

On April 14, 2017, representatives for the estate of a deceased individual filed a civil lawsuit in the Suffolk Superior Court, in Boston, Massachusetts, against the Company and Harvard Bioscience. The complaint alleges that the decedent’s injury and death were caused by two tracheal implants that incorporated synthetic trachea scaffolds and a biologic component combined by the implanting surgeon with a bioreactor, and surgically implanted in the decedent in two surgeries performed in 2012 and 2013. The civil complaint seeks a non-specific sum of money to compensate the plaintiffs. This civil lawsuit relates to the Company’s first-generation trachea scaffold technology for which the Company discontinued development in 2014, and not to the Company’s current Cellspan technology nor to its lead development product candidate, the Cellspan Esophageal Implant. The Company intends to vigorously defend this case. While the Company believes that such claim lacks merit, the Company is unable to predict the ultimate outcome of such litigation. In accordance with a separation and distribution agreement between Harvard Bioscience and the Company relating to the spin-off, the Company would be required to indemnify Harvard Bioscience against losses that Harvard Bioscience may suffer as a result of this litigation. The Company has been informed by its insurance provider that the case has been accepted as an insurable claim under the Company’s product liability insurance policy. The Company does not believe a loss is probable at this time and therefore has not accrued any amounts for this contingent liability.

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.

10.  Income Taxes

The Company did not provide for any income taxes in its consolidated statements of operations for the three and six months ended June 30, 2020 and 2019. The Company has provided a valuation allowance for the full amount of its net deferred tax assets because, at June 30, 2020 and December 31, 2019, it was more likely than not that any future benefit from deductible temporary differences and net operating loss and tax credit carryforwards would not be realized.

The Company has not recorded any amounts for unrecognized tax benefits as of June 30, 2020 or December 31, 2019. As of June 30, 2020 and December 31, 2019, the Company had no accrued interest or tax penalties recorded related to income taxes. The Company is subject to U.S. federal income tax and Massachusetts state income tax. The statute of limitations for assessment by the IRS and state tax authorities is open for all periods from inception through December 31, 2018; currently, no federal or state income tax returns are under examination by the respective taxing authorities.

Under the provisions of the Internal Revenue Code, the net operating loss and tax credit carryforwards are subject to review and possible adjustment by the IRS and state tax authorities. Net operating loss and tax credit carryforwards may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant shareholders over a three-year period in excess of 50 percent, as defined under Sections 382 and 383 of the Internal Revenue Code, respectively, as well as similar state provisions. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value of the Company immediately prior to the ownership change. Subsequent ownership changes may further affect the limitation in future years. The Company has recently completed several equity financing transactions which have either individually or cumulatively resulted in a change in control as defined by Sections 382 and 383 of the Internal Revenue Code, or could result in a change in control in the future. The Company does not believe the impact of any limitation on the use of its net operating loss or credit carryforwards will have a material impact on the Company’s consolidated financial statements since the Company has a full valuation allowance against its deferred tax assets due to the uncertainty regarding future taxable income for the foreseeable future.

For all periods through June 30, 2020, the Company generated research credits but has not conducted a study to document the qualified activities. This study may result in an adjustment to the Company’s research and development credit carryforwards; however, until a study is completed and any adjustment is known, no amounts are being presented as an uncertain tax position. A full valuation allowance has been provided against the Company’s research and development credits and, if an adjustment is required, this adjustment would be offset by an adjustment to the deferred tax asset established for the research and development credit carryforwards and the valuation allowance.

Coronavirus Aid, Relief and Economic Security Act

In response to the COVID-19 pandemic, the CARES Act was signed into law in March 2020. The CARES Act lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (2017 Tax Act). Corporate taxpayers may carryback federal and state net operating losses (NOLs) originating during 2018 through 2020 for up to five years, which was not previously allowed under the 2017 Tax Act. The CARES Act also eliminates the 80% of taxable income limitations by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018, 2019 or 2020. Taxpayers may generally deduct interest up to the sum of 50% of adjusted taxable income plus business interest income (30% limit under the 2017 Tax Act) for tax years beginning January 1, 2019 and 2020. The CARES Act allows taxpayers with alternative minimum tax credits to claim a refund in 2020 for the entire amount of the credits instead of recovering the credits through refunds over a period of years, as originally enacted by the 2017 Tax Act.

In addition, the CARES Act raises the corporate charitable deduction limit to 25% of taxable income and makes qualified improvement property generally eligible for 15-year cost-recovery and 100% bonus depreciation. The enactment of the CARES Act did not result in any material adjustments to the Company's income tax provision for the three and six months ended June 30, 2020, or to the Company's net deferred tax assets as of June 30, 2020.

SBIR Award

SBIR Award

On March 28, 2018, the Company was awarded a Fast-Track Small Business Innovation Research (SBIR) grant by the Eunice Kennedy National Institute of Child Health and Human Development (NICHD) of the National Institutes of Health to support testing of pediatric Cellspan Esophageal Implants. The award for Phase I, which was earned over the nine months ended September 30, 2018, provided for the reimbursement for up to approximately  $0.2 million of qualified research and development costs.

On October 26, 2018, the Company was awarded Phase II of the SBIR grant totaling $1.1 million to support expenses for development, testing, and translation to the clinic through September 2019. As of September 30, 2019, the Company had expended $0.6 million of the $1.1 million awarded, and in December 2019 submitted a modified Phase II grant development plan totaling $1.0 million, including $0.5 million unspent from the Phase 2 grant awarded and an additional $0.5 million for the next year of the project, subject to the NICHD approval. This modified development plan was approved by the NICHD on August 3, 2020. See Note 11. The SBIR grant has the potential to provide a total award of approximately $1.8 million, of which approximately $0.8 million has been recognized to date. The Company did not recognize grant income from Phase II of the SBIR grant for the three and six months ended June 30, 2020.

Grant income is recognized when qualified research and development costs are incurred and recorded in other income (expense), net in the consolidated statements of operations. When evaluating grant revenue from the SBIR grant, the Company considered accounting requirements under the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 606, Revenue From Contracts With Customers. The Company concluded that ASC 606 did not apply as there is no exchange of goods or services or an exchange of intellectual property between the parties; therefore, the Company presents grant income in other income.
