Note 2—Summary of significant accounting policies and basis of presentation

The Company’s significant accounting policies are disclosed in the audited consolidated financial statements for the year ended December 31, 2020, included in the Company’s final prospectus that forms part of the Company’s Registration Statement on Form S-1 (Reg. No. 333-256648) and filed with the SEC pursuant to Rule 424(b)(4) on June 21, 2021. Since the date of those financial statements, there have been no changes to its significant accounting policies.

Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the interim period reporting requirements of Form 10-Q and Article 10 of Regulation S-X. The consolidated balance sheet as of September 30, 2021, the consolidated statements of operations and comprehensive loss, and consolidated statements of convertible preferred stock and stockholders’ equity (deficit) for the three and nine months ended September 30, 2021 and 2020, and the consolidated statements of cash flows for the nine months ended September 30, 2021 and 2020 are unaudited, but, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, which we consider necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented.  The results for any interim period are not necessarily indicative of results for the year ending December 31, 2021 or for any other subsequent interim period.  The consolidated balance sheet at December 31, 2020 has been derived from our audited consolidated financial statements.

Merger and capital restructuring

Upon the conversion of Century Therapeutics, LLC to a corporation and the merger of the newly converted corporation with Prior Century, the existing capital structure of Century Therapeutics, LLC was restructured with no consideration transferred. In accordance with ASC 505-10-S99-4, such a restructuring requires retroactive effect within the balance sheets presented. As such, the Company retroactively adjusted its consolidated balance sheets to cancel the existing LLC units and give effect to their conversion into capital

stock of the Company as if those effects happened as of January 1, 2020. See Note 10 for further information on the Company’s capital restructuring.

Reverse Stock Split

In June 2021, the Company’s Board of Directors approved an amendment to the Company’s amended and restated certificate of incorporation to effect a 2.5161-for-1 reverse stock split of the Company’s common stock, which was effected on June 11, 2021. Stockholders entitled to fractional shares as a result of the reverse stock split will receive a cash payment in lieu of receiving fractional shares. The par value of the common stock was not adjusted as a result of the reverse stock split. Shares of common stock underlying outstanding stock options and other equity instruments were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased in accordance with the terms of the appropriate securities agreements. Shares of common stock reserved for issuance upon the conversion of the convertible preferred stock were proportionately reduced and the respective conversion prices were proportionately increased. All common share and per share data have been retrospectively revised to reflect the reverse stock split.

Segment information

Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions on how to allocate resources and assess performance. The Company views its operations and manages the business as one operating segment.

Use of estimates

The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of expenses during the reporting period. Estimates and assumptions are primarily made in relation to the valuations supporting stock compensation and the estimation of the incremental borrowing rate for operating leases. If actual results differ from the Company’s estimates, or to the extent these estimates are adjusted in future periods, the Company’s results of operations could either benefit from, or be adversely affected by, any such change in estimate.

Concentration of credit risk and other risks and uncertainties

Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist of cash, cash equivalents, U.S. Treasury bills and bonds, as well as corporate bonds. Cash and cash equivalents, as well as short and long-term investments include a checking account and asset management accounts held by a limited number of financial institutions. At times, such deposits may be in excess of insured limits. As of September 30, 2021 and December 31, 2020, the Company has not experienced any losses on its deposits of cash and cash equivalents.

The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, rapid technological change, uncertainty of market acceptance of its products, competition from substitute products and larger companies, protection of proprietary technology, strategic relationships, and dependence on key individuals.

Products developed by the Company require clearances from the U.S. Food and Drug Administration or other international regulatory agencies prior to commercial sales. There can be no assurance the Company’s future products will receive the necessary clearances. If the Company was denied clearance, clearance was delayed, or if the Company was unable to maintain clearance, it could have a material adverse impact on the Company.

In January 2020, the World Health Organization declared the outbreak of a novel coronavirus (COVID-19) as a “Public Health Emergency of International Concern,” which continues to spread throughout the world and has adversely impacted global commercial activity and contributed to significant declines and volatility in financial markets. The COVID-19 outbreak and government responses are creating disruption in global supply chains and adversely impacting many industries. The outbreak could have a continued material adverse impact on economic and market conditions and trigger a period of global economic slowdown. Vaccines were introduced late in the fourth quarter of 2020 and became widely available by the end of the first quarter of 2021. While the vaccines have proven effective in reducing the severity and mortality of COVID-19 including the variants that have evolved to date, the overall vaccination rate in the United States may not have reached the level required for herd immunity. Certain variants of COVID-19, such as the delta variant, are proving to be more easily spread than earlier variants. The incomplete vaccination rate, and the emergence of new variants which could prove resistant to existing vaccines could again result in major disruptions to businesses and markets worldwide. The Company continues to monitor the impact of the COVID-19 outbreak closely. The extent to which the COVID-19 outbreak will impact its operations or financial results is uncertain.

Fair value of financial instruments

The Company discloses and recognizes the fair value of its assets and liabilities using a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The hierarchy gives the highest priority to valuations based upon unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to valuations based upon unobservable inputs that are significant to the valuation (Level 3 measurements). The guidance establishes three levels of the fair value hierarchy as follows:

Level 1

Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date;

Level 2

Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be active;

Level 3

Inputs are unobservable in which there is little or no market data available, which require the reporting entity to develop its own assumptions that are unobservable.

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.

Cash and cash equivalents

Management considers all highly liquid investments with an insignificant interest rate risk and original maturities of three months or less to be cash equivalents.

Restricted cash

As of September 30, 2021 and December 31, 2020, the Company had $1,717 and $517 in cash on deposit to secure certain lease commitments. Restricted cash is recorded separately in the Company’s consolidated balance sheets.

The following provides a reconciliation of the Company’s cash, cash equivalents, and restricted cash as reported in the consolidated balance sheets to the amounts reported in the consolidated statements of cash flows:

Fixed maturity securities

The Company invests in fixed maturity securities including U.S. Treasury bills and bonds as well as corporate bonds. The investments are classified as available-for-sale and reported at fair value. Unrealized gains or losses are determined by comparing the fair market value of the securities with their cost or amortized cost. Realized gains and losses on investments are recorded on the trade date and are included in the statement of operations. The cost of securities sold is based on the specified identification method. Investment income is recognized as earned and discounts or premiums arising from the purchase of debt securities are recognized in investment income using the interest method over the remaining term of the security. Securities with an original maturity date greater than three months that mature within one year of the balance sheet date are classified as short-term, while investments with a maturity date greater than one year are classified as long-term.

Foreign currency translation

The reporting currency of the Company is the U.S. dollar. The functional currency of Century Canada is the Canadian dollar. Assets and liabilities of Century Canada are translated into U.S. dollars based on exchange rates at the end of each reporting period. Expenses are translated at average exchange rates during the reporting period. Gains and losses arising from the translation of assets and liabilities are included as a component of accumulated other comprehensive loss or income on the company’s consolidated balance sheets. Gains and losses resulting from foreign currency transactions are reflected within the Company’s consolidated statements of operations and comprehensive loss. The Company has not utilized any foreign currency hedging strategies to mitigate the effect of its foreign currency exposure.

Intercompany payables and receivables are considered to be long-term in nature and any change in balance due to foreign currency fluctuation is included as a component of the Company’s consolidated comprehensive loss and accumulated other comprehensive loss within the Company’s consolidated balance sheets.

Basic and diluted net loss per common shares

Basic net loss per common share is computed by dividing net loss applicable to common shareholders by the weighted-average number of common shares outstanding during the period. The Company computes diluted net loss per common share by dividing the net loss applicable to common shareholders by the sum of the weighted- average number of common shares outstanding during the period plus the potential dilutive effects of its warrants, restricted stock and stock options to purchase common shares, but such items are excluded if their effect is anti-dilutive. Because the impact of these items are anti-dilutive during periods of net loss, there were no differences between the Company’s basic and diluted net loss per common share for the three and nine months ended September 30, 2021 and 2020.

Early exercised options

The Company allowed certain of its employees and its consultants to exercise options granted under the 2018 Plan (Note 15) prior to vesting. The shares related to early exercised stock options are subject to the Company’s repurchase right upon termination of employment or services at the lesser of the original purchase price or fair market value at the time of repurchase. In order to vest, the holders are required to provide continued service to the Company. The early exercise by an employee or consultant of a stock option

is not considered to be a substantive exercise for accounting purposes, and therefore, the payment received by the employer for the exercise price is recognized as a liability. For accounting purposes, unvested early exercised shares are not considered issued and outstanding and therefore not reflected as issued and outstanding in the accompanying consolidated balance sheets or the consolidated statements of changes in convertible preferred stock and stockholders’ equity (deficit) until the awards vest. The deposits received are initially recorded in deposit liability. The liabilities are reclassified to common stock and additional paid-in-capital as the repurchase right lapses. At September 30, 2021, $3,220 was recorded in deposit liability related to shares held by employees and nonemployees that were subject to repurchase. At December 31, 2020, there was no deposit liability as the initial deposit liability was recognized on February 25, 2021 when the merger discussed in Note 2 occurred.

All shares that were early exercised by the executives of the Company are considered legally issued, however, for accounting purposes, only vested shares are considered issued. Below is a reconciliation of shares issued and outstanding:

Restricted stock

In 2018, the Company issued 1,704,256 restricted stock awards at a purchase price of $0.03 per share. In 2019, the Company issued 850,312 restricted stock awards at a weighted average purchase price of $0.70 per share. In October 2019, the Company repurchased 298,080 shares at $1.03 per share. In 2021, the Company issued 194,320 restricted stock awards. As of September 30, 2021, the number of restricted stock awards vested were 1,632,594. For accounting purposes, unvested restricted stock awards are not considered issued and outstanding and therefore are not reflected as issued and outstanding in the accompanying consolidated balance sheets or the consolidated statements of changes in convertible preferred stock and stockholders’ equity (deficit) until the awards vest. The Company recorded stock-based compensation expense for these awards of $567 and $695, respectively, for the three and nine months ended September 30, 2021, in the statements of operations and comprehensive loss. The Company recorded stock-based compensation expense for these awards of $39 and $117, respectively, for the three and nine months ended September 30, 2020, in the statements of operations and comprehensive loss.

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for convertible debt instruments and convertible preferred stock by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. The update also requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share. The new guidance is effective for annual periods beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. This update can be adopted on either a fully retrospective or a modified retrospective basis. The Company adopted ASU 2020-06, effective January 1, 2021, which did not have a material effect on the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework— Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which eliminates, adds, and modifies certain disclosure requirements for fair value measurements. ASU 2018-13 is effective for the Company for fiscal years beginning after December 15, 2020, and earlier adoption is

permitted. The Company adopted this standard on January 1, 2021 and adoption had no impact on its consolidated financial statements.
