Summary of Significant Accounting Policies

The accounting policies underlying the accompanying unaudited condensed consolidated financial statements are those set forth in Note 2 to the consolidated financial statements for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Biostage and its three wholly-owned subsidiaries, Harvard Apparatus Regenerative Technology Limited (Hong Kong), Harvard Apparatus Regenerative Technology GmbH (Germany) and Biostage Limited (UK). The functional currency for Biostage and these subsidiaries is the U.S dollar. All intercompany balances and transactions have been eliminated in consolidation.

Basis of Presentation

The condensed consolidated financial statements reflect the Company’s financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States, or U.S. GAAP.

Use of Estimates

The process of preparing condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include, but are not limited to, share-based compensation, valuation of warrant liability, accrued expenses and the valuation allowance for deferred income taxes. Actual results could differ from those estimates.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets as follows:

Leasehold improvements	Shorter of expected useful life or lease term
Furniture, machinery and equipment, computer equipment and software		3-7 years

Maintenance and repairs are charged to expense as incurred, while any additions or improvements are capitalized.

Net Loss Per Share

Basic net loss per share is calculated by dividing net loss applicable to common stockholders by the weighted-average number of shares outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by adjusting the weighted-average number of shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method. For purposes of the diluted net loss per share calculation, warrants to purchase common stock and stock options are considered to be common stock equivalents, but have been excluded from the calculation of diluted net loss per share, as their effect would be anti-dilutive for all periods presented. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented.

Unaudited Interim Financial Information

The accompanying interim condensed consolidated balance sheet as of March 31, 2023, condensed consolidated interim statements of operations, stockholders’ deficit and cash flows for the three months ended March 31, 2023 and 2022 are unaudited. The interim unaudited condensed consolidated financial statements have been prepared in accordance with GAAP on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments necessary for a fair statement of the Company’s financial position as of March 31, 2023, its condensed consolidated results of operations, stockholders’ deficit and cash flows for the three months ended March 31, 2023 and 2022. The financial data and other information disclosed in these notes related to the three months ended March 31, 2023 and 2022 are unaudited. The results for the three months ended March 31, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023, any other interim periods or any future year or period.

Recently Adopted Accounting Pronouncements

Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s condensed consolidated financial statements upon adoption.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-12). The new standard requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. It also limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. The Company adopted this standard on January 1, 2023, and the adoption of ASU 2016-13 did not have a material impact on its consolidated financial statements.
