Rhea-AI Filing Summary

Century Therapeutics, Inc. reported a net loss of $21.6 million for the three months ended March 31, 2026, compared with net income of $76.6 million a year earlier, when results included a large one-time collaboration revenue from Bristol-Myers Squibb.

Collaboration revenue was $0 this quarter versus $109.2 million in the prior-year period. Research and development expenses declined to $17.1 million from $26.6 million, and general and administrative expenses fell to $6.6 million from $8.4 million, reflecting cost controls and portfolio focus.

Cash, cash equivalents and investments totaled about $217.0 million, and management believes this will fund operations into the first quarter of 2029. During the quarter, the company closed a $126.4 million private placement, significantly increasing shares outstanding while supporting development of lead iPSC-derived cell therapy programs CNTY-813, CNTY-308 and CNTY-101.

Insights

Loss replaces prior one-time revenue, but balance sheet strengthened by new equity.

Century Therapeutics swung from prior-year profit to a $21.6M net loss as collaboration revenue fell to zero after the Bristol-Myers Squibb agreement ended. Operating expenses decreased, with research and development down to $17.1M and general and administrative down to $6.6M, indicating tighter spending.

The company ended the quarter with $217.0M in cash, cash equivalents and investments, helped by a $126.4M private placement. Management states this should fund operations into the first quarter of 2029, supporting IND-enabling and early clinical work on CNTY-813, CNTY-308 and CNTY-101.

The investment case now rests more heavily on internal pipeline execution rather than collaboration revenue. Subsequent filings and clinical updates around the planned 2026 IND for CNTY-813 and initiation of CNTY-308 studies will be important for assessing progress of this iPSC-derived cell therapy portfolio.

Private placement proceeds $126.4M Net proceeds from January 2026 offering
allogeneic cell therapies financial
"We are a biotechnology company harnessing the power of allogeneic pluripotent stem cell therapies"
induced pluripotent stem cells financial
"our focus on induced pluripotent stem cells, or iPSCs, which possess the unique ability to self-renew indefinitely"
Induced pluripotent stem cells (iPSCs) are adult cells that scientists have reprogrammed to behave like embryonic stem cells, meaning they can become many different cell types. For investors, iPSCs matter because they are a flexible platform for developing new drugs, testing safety, and creating personalized therapies; think of them as blank building blocks that can be used to prototype treatments and reduce development risk before large clinical bets.
contingent consideration liability financial
"Contingent consideration liability, short-term"
Contingent consideration liability is an obligation a company records when it may owe future payments tied to the outcome of a past deal, such as extra cash or shares if certain targets are met. Think of it like a promised bonus that depends on future results; it matters to investors because it can change a company's reported debt, future cash needs, and reported earnings volatility as those contingent payments are re-estimated over time.
available-for-sale financial
"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"
A classification for bonds, stocks or other investments that a company plans to keep but might sell before they reach full term. Think of it like items a shop keeps on a shelf for potential sale: their market value can go up or down while the company holds them, and those unrealized gains or losses are shown separately from operating profit until they are sold. Investors watch this because large swings can change a company’s reported net worth and signal how much flexibility it has to raise cash quickly.
At-The-Market financial
"to provide for the offering, issuance and sale of up to an aggregate amount of $150,000 of common stock from time to time in “at-the-market” offerings (the “ATM Program”)"
"At-the-market" is a method for companies to sell new shares of stock directly into the open market over time, rather than all at once. It allows companies to raise money gradually, similar to selling slices of a pie instead of the entire pie at once, which can help manage the sale's impact on the stock price. This approach gives investors a steady supply of shares while providing companies with flexible funding options.
Private Placement financial
"we entered into a securities purchase agreement with the 2026 Investors in connection with the 2026 Private Placement"
A private placement is a way for companies to raise money by selling securities directly to a small group of investors instead of through a public offering. This process is often quicker and less regulated, making it similar to offering a special, exclusive investment opportunity to select individuals or institutions. For investors, it can provide access to unique investment options that are not available on public markets.

NOTES TO FINANCIAL STATEMENTS

(Unaudited)

(in thousands, except share and per share amounts)

Note 1—Organization and description of the business

Century Therapeutics, Inc. (the “Company”) is an innovative biotechnology company developing transformative allogeneic cell therapies to create products for the treatment of autoimmune diseases, including Type 1 diabetes, and cancer. Since inception, the Company has devoted substantially all of its time and efforts to performing research and development activities, building infrastructure and raising capital. The Company is incorporated in the state of Delaware.

Principles of Consolidation

The consolidated financial statements include the consolidated financial position and consolidated results of operations of the Company and the Company’s subsidiaries, Clade Therapeutics (“Clade”) and Gadeta B.V. (“Gadeta”). All intercompany balances and transactions have been eliminated in consolidation.

Liquidity

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. The Company has limited operating history and its prospects are subject to risks, expenses, and uncertainties frequently encountered by companies in the biotechnology and pharmaceutical industries. These risks include, but are not limited to, the uncertainty of availability of additional financing and the uncertainty of achieving future profitability.

Since inception, the Company has incurred negative cash flows from operations and net losses in most periods. During the three months ended March 31, 2026, the Company recognized a net loss of $21,645 and the Company used $25,262 of cash in operating activities. Cash and cash equivalents and investments were $216,972 at March 31, 2026. Management expects to incur additional losses in the future to fund its operations and conduct product research and preclinical and clinical development and recognizes the need to raise additional capital to fully implement its business plan. The Company believes it has adequate cash and financial resources to operate for at least the next 12 months from the date of issuance of these consolidated financial statements.

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

Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. 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 March 31, 2026, and the consolidated statements of operations, comprehensive income (loss), changes in stockholders’ equity and cash flows for the three months ended March 31, 2026 and 2025, are unaudited, but, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, which the Company considers 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, 2026 or for any other subsequent interim period. The consolidated balance sheet at December 31, 2025 has been derived from the Company’s audited consolidated financial statements.

.

Table of Contents

Use of estimates

The preparation of consolidated financial statements in conformity with U.S. 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, the estimation of the incremental borrowing rate for operating leases, and intangible assets acquired in business combinations. 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 March 31, 2026 and December 31, 2025, 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 (the “FDA”) 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.

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.

Table of Contents

Cash and cash equivalents

Management considers all highly liquid investments with original maturities of three months or less to be cash equivalents.

Restricted cash

As of March 31, 2026 and December 31, 2025, the Company had $2,709 and $3,158, respectively, 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:

Investments

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. Unrealized gains and losses on investments are recorded in other comprehensive income (loss) on the consolidated statements of operations and comprehensive income (loss). 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.

Property and equipment, net

Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which is generally five years. Leasehold improvements are amortized over the shorter of the asset’s useful life or the remaining term of the lease. Construction in progress includes direct cost related to the construction of leasehold improvements and is stated at original cost. Such costs are not depreciated until the asset is completed and placed into service. Once the asset is placed into service, these capitalized costs will be allocated to leasehold improvements and will be depreciated over the shorter of the asset’s useful life or the remaining term of the lease. Computer software and equipment includes implementation costs for cloud-based software and network equipment.

Expenditures for major additions and improvements are capitalized, while minor replacements, maintenance, and repairs are charged to expense as incurred. When property is retired or otherwise disposed of, the costs and accumulated depreciation are removed from the respective accounts, with any resulting gain or loss recognized concurrently.

11

Table of Contents

Research and development expenses

Research and development expenses include costs directly attributable to the conduct of research and development programs, including the cost of salaries, payroll taxes, employee benefits, stock compensation, materials, supplies, rent, depreciation on and maintenance of research equipment with alternative future use, and the cost of services provided by outside contractors. All costs associated with research and development are expensed as incurred.

Clinical trial costs are a component of research and development expenses. The Company expenses costs for its clinical trial activities performed by third parties, including clinical research organizations and other service providers, as they are incurred, based upon estimates of the work completed over the life of the individual study in accordance with associated agreements. The Company uses information it receives from internal personnel and outside service providers to estimate the clinical trial costs incurred.

Stock-based compensation

Employees, consultants, and members of the Board of Directors of the Company have received stock options and restricted stock of the Company. The Company recognizes the cost of the stock-based compensation incurred as its employees and board members vest in the awards. The Company accounts for stock-based compensation arrangements in accordance with provisions of Accounting Standards Codification (“ASC”) 718, Compensation—Stock Compensation. ASC 718 requires the recognition of compensation expense, using a fair-value based method, for costs related to all share-based payments including stock options. ASC 718 requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The Company uses the Black-Scholes option-pricing model (“Black Scholes”) to determine the fair value of options granted. The Company’s stock-based awards are subject to service-based vesting conditions and performance-based vesting conditions. Compensation expense related to awards to employees and directors with service-based vesting conditions is recognized on a straight-line basis based on the grant date fair value over the associated service period of the award, which is generally the vesting term. For performance-based awards, the Company reassesses at each reporting date whether achievement of the performance condition is probable and accrues compensation expense if and when achievement of the performance condition is probable.

Black Scholes requires inputs based on certain subjective assumptions, including (i) the expected stock price volatility, (ii) the expected term of the award, (iii) the risk-free interest rate and (iv) expected dividends. The historical volatility is calculated based on a period of time commensurate with expected term assumption. The risk-free interest rate is based on U.S. Treasury securities with a maturity date commensurate with the expected term of the associated award. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on its common stock. Forfeitures are recognized as they occur.

Warrants

Warrants are accounted for in accordance with applicable accounting guidance provided in ASC Topic 815, Derivatives and Hedging—Contracts in Entity’s Own Equity, as either derivative liabilities or as equity instruments depending on the specific terms of the warrant agreement.

Foreign currency translation

The reporting currency of the Company is the U.S. dollar. The functional currency of Century Canada is the Canadian dollar. The functional currency of Gadeta is the Euro. Assets and liabilities of Century Canada and Gadeta 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

12

Table of Contents

from foreign currency transactions are reflected within the Company’s consolidated statements of operations and comprehensive income (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 income (loss) and accumulated other comprehensive income within the Company’s consolidated balance sheets.

Basic and diluted net income (loss) per common share

Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding, including any pre-funded warrants to purchase shares of common stock that may be outstanding during the period. The Company computes diluted net income (loss) per common share by dividing the net income (loss) 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.

Acquisition-Related Contingent Consideration

Acquisition-related contingent consideration consist of our future obligation owed to shareholders of Clade and Gadeta and includes contingent milestone payments, earn out considerations, and indemnification obligations. Acquisition-related contingent consideration was recorded on the acquisition date at the estimated fair value of the obligation, in accordance with the acquisition method of accounting. The fair value measurement is based on significant inputs that are unobservable in the market and thus represents a Level 3 fair value measurement. The fair value of the acquisition-related contingent considerations are remeasured each reporting period, with changes in fair value recorded in the consolidated statements of operations and comprehensive income (loss) within general and administrative expense.

Business Combinations

The Company accounts for business combinations using the acquisition method of accounting in accordance with ASC 805, Business Combinations. Identifiable assets acquired and liabilities assumed are recorded at their acquisition date fair values. The excess of the fair value of purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Acquisition related costs are expensed as incurred. Upon acquisition, the accounts and results of operations are consolidated as of and subsequent to the acquisition date.

When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible assets. The Company utilizes commonly accepted valuation techniques, such as the income approach in establishing the fair value of intangible assets.

13

Table of Contents

Intangible Assets

Indefinite-lived intangibles are carried at the initially recorded fair value less any recognized impairment. Indefinite-lived intangibles are tested at least annually for impairment. Impairment assessments are conducted more frequently if certain conditions exist, including a change in the competitive landscape, any internal decisions to pursue new or different technology strategies, or a significant change in the marketplace, including changes in the size of the market for the Company’s products. In performing the impairment test, the Company estimates the fair value of the indefinite-lived intangible asset and compares it to the carrying value. If the carrying value exceeds the estimated fair value, the Company records an impairment loss for the difference. For the three months ended March 31, 2026 and March 31, 2025, there were no impairment charges on the Company’s indefinite-lived intangible assets.

Recent accounting pronouncements

In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”). The ASU includes enhanced disclosure requirements, which mandate transparency in financial statements by requiring detailed disclosures of specific expenses like inventory purchases, employee compensation, depreciation, and intangible asset amortization. In January 2025, the FASB issued ASU 2025-01, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40) An Amendment of the FASB ASC, Clarifying the Effective Date, which clarifies that public business entities are required to adopt the ASU 2024-03 guidance in annual reporting periods beginning after December 15, 2026 and interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of adopting this pronouncement on the Company’s consolidated financial statements and disclosures.

There were no transfers between levels during the period ended March 31, 2026. The Company uses the services of its investment manager, which uses widely accepted models for assumptions in valuing securities with inputs from major third-party data providers.

The Company classifies all of its investments in fixed maturity debt securities as available-for-sale and, accordingly, are carried at estimated fair value.

The amortized cost, gross unrealized gains and losses, and fair value of investments in fixed maturity securities are as follows as of March 31, 2026:

The Company has evaluated the unrealized losses on the fixed maturity securities and determined that they are not attributable to credit risk factors. For fixed maturity securities, losses in fair value are viewed as temporary if the fixed maturity security can be held to maturity and it is reasonable to assume that the issuer will be able to service the debt, both as to principal and interest.

At March 31, 2026 and December 31, 2025, the Company had 157 and 17 available-for-sale investment debt securities in an unrealized loss position without an allowance for credit losses, respectively. Unrealized losses on corporate debt securities have not been recognized into income because the issuers’ bonds are of high

15

Table of Contents

credit quality (rated BBB+ or higher) and the decline in fair value is largely due to market conditions and or changes in interest rates. Management does not intend to sell and it is likely that management will not be required to sell the securities prior to the anticipated recovery of their amortized cost basis. The issuers continue to make timely payments on the bonds. The fair value is expected to recover as the bonds approach maturity.

As of March 31, 2026 and December 31, 2025, accrued interest receivable on available-for-sale investment debt securities totaling $1,373 and $393, respectively, is excluded from the estimate of credit losses and is included in prepaid expenses and other current assets.

Note 6—Bristol-Myers Squibb Collaboration

On January 7, 2022, the Company entered into the Collaboration Agreement with Bristol-Myers Squibb to collaborate on the research, development and commercialization of iNK and iT cell programs for hematologic malignancies and solid tumors . The Collaboration Agreement was within the scope of ASC 808, Collaborative Arrangements, as both parties were active participants in the arrangement and are exposed to significant risks and rewards. While this arrangement was in the scope of ASC 808, the Company analogizes to ASC 606 for the accounting for the Collaboration Agreement, including for the delivery of goods and services (i.e., units of account). Revenue recognized by analogizing to ASC 606 is recorded as collaboration revenue in the statements of operations.

Following an internal corporate portfolio prioritization process, Bristol-Myers Squibb notified the Company on December 12, 2024 that it would be terminating the Collaboration Agreement in its entirety without cause. The termination was effective on March 12, 2025. As a result of the notice of termination, the Company concluded that the research and development services being provided to Bristol-Myers Squibb were substantially complete as of December 31, 2024, and accordingly, the remaining transaction price allocated to that performance obligation was recorded in the fourth quarter of 2024. The remaining transaction price related to the license option rights, which represented a material right of $109,164 was recognized in the first quarter of 2025 when the option right expired upon the termination of the Collaboration Agreement. There will be no future collaboration revenues recognized under the Collaboration Agreement.

Note 7—Commitments and contingencies

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues a liability for such matters when future expenditures are probable and such expenditures can be reasonably estimated.

FCDI Agreements

The Company owns a non-exclusive license agreement with FujiFilm Cellular Dynamics, Inc. (“FCDI”). The license provides the Company with certain patents and know-how related to the reprogramming of human somatic cells to induce pluripotent stem cells (“iPSCs”) (“Reprogramming License Agreement”). Under this agreement, the Company is required to make certain developmental and regulatory milestone payments as well as royalty payments upon commercialization. Royalties are in the low single digits on the sale of all licensed products.

The Company also owns an exclusive license agreement with FCDI (“Differentiation Licenses Agreement”). The Differentiation Licenses Agreement provides the Company with patents and know-how related to human iPSC exclusively manufactured by FCDI.

In October 2019, the Company entered into the Master Collaboration Agreement with FCDI (“Collaboration Agreement”), whereby FCDI provides certain services to the Company to develop and manufacture iPSCs and immune cells derived therefrom. FCDI provides services in accordance with the approved research plan

17

Table of Contents

and related research budget. The initial research plan covered the period from October 2019 through March 31, 2022. In July, 2022 the Company amended the Collaboration Agreement to extend the term through September 30, 2025, and in September 2023, the Company amended the Collaboration Agreement in connection with the Autoimmune License (as defined below).

In March 2021, the Company entered into a Manufacturing Agreement with FCDI (“Manufacturing Agreement”), pursuant to which FCDI provides certain agreed upon technology transfer, process development, analytical testing and cGMP manufacturing services to the Company.

In January 2022, the Company and FCDI entered into a letter agreement (the “Letter Agreement”), which amended the Reprogramming License Agreement, Differentiation License Agreement and Manufacturing Agreement (the “FCDI Agreements”) pursuant to the Company’s Research Collaboration and License Agreement with Bristol-Myers Squibb. Pursuant to the Letter Agreement, and in consideration for amending the FCDI Agreements, the Company paid to FCDI an upfront payment of $10,000 and will pay FCDI (i) a percentage of any milestone payments received by the Company under the FCDI Collaboration Agreement in respect of achievement of development or regulatory milestones specific to Japan, and (ii) a percentage of all royalties received by the Company under the FCDI Collaboration Agreement in respect of sales of products in Japan.

In September 2023 the Company and FCDI entered into a worldwide license agreement whereby FCDI will grant non-exclusive licenses to the Company for certain patent rights and know-how related to cell differentiation and reprogramming for the development and commercialization of iPSC-derived therapies for the treatment of inflammatory and autoimmune diseases (the “Autoimmune License”). In addition, the Company and FCDI entered into an amendment to each of the Reprogramming License and the Differentiation License to expand the licenses related to the development and commercialization of iPSC-derived cancer immunotherapeutic to also include inflammatory and autoimmune diseases. Under the terms of these agreements, FCDI will be eligible to receive certain development and regulatory milestone payments as well as low single-digit royalties related to products developed in connection with such agreements. 

During the three months ended March 31, 2026 and 2025 the Company made payments of $0 and $1,517 and incurred research and development expenses of $0 and $1,492, respectively, recorded within research and development expenses in its consolidated statements of operations and comprehensive income (loss).

Distributed Bio Master Service Agreement

On July 24, 2019, the Company entered into a Master Service Agreement with Distributed Bio, Inc (“DBio”), whereby DBio will screen for protein binders that bind to specific therapeutic targets (the “Master Service Agreement”). The Company pays for such services according to a payment schedule, and if the Company brings the protein binders into the clinic for further development, DBio will receive milestone payments of up to $16,100 in total for each product as the products move through the clinical development and regulatory approval processes. No milestone payments were due since the inception of the agreement.

The Company had $0 within accounts payable as of March 31, 2026 and December 31, 2025, in its consolidated balance sheets related to the Master Service Agreement. During the three months ended March 31, 2026 and 2025, there were $0 and $66 in research and development expenses, respectively, related to this arrangement.

iCELL Inc. Sublicense Agreement

In March 2020, the Company entered into a Sublicense Agreement with iCELL Inc (“iCELL”) whereby iCELL granted the Company a license of certain patents and technology. The Company will pay iCELL royalties in the low single digits on net sales of the licensed product. In addition to the earned royalties, the Company will pay sales milestones, not to exceed $70,000, for the sales of the licensed product. iCELL is also eligible to

18

Table of Contents

receive payments of up to $4,250 in development and regulatory approval milestone payments. No milestones or royalties were due as of March 31, 2026 or March 31, 2025.

Clade Therapeutics

In connection with the acquisition of Clade Therapeutics in 2024, the Company is subject to a contingent milestone payment to the shareholders of Clade. The milestone payment is $10,000 and is payable in cash, shares of Century, or a combination thereof, at the discretion of Century.

Catalent Dusseldorf GmbH

On December 12, 2022, Clade entered into a non-exclusive license agreement with Catalent Dusseldorf GmbH (“Catalent”), which was subsequently amended in March 2026, pursuant to which Catalent granted Clade a worldwide, non-exclusive, non-transferrable, royalty-bearing license under all rights owned or controlled by Catalent to one of its GMP-grade iPSC cell lines derived from human cord blood CD34+ cells, to develop, have developed, make, have made, use, have used, sell, offer for sale, have sold, distribute, have distributed, import, have imported and otherwise exploit or have exploited cell therapy products. The license (as amended, the “Catalent License”), permits the genetic modification of the licensed cell line and the development and commercialization of resulting cell therapy products for any indication. We have a right to use the Catalent License as a result of our acquisition of Clade.

Under the Catalent License, we may grant sublicenses to third parties to develop, manufacture and commercialize resulting products, but we may not sublicense the original cell line itself. Catalent retains ownership of the original cell line, and we own the modified cells and resulting products that we make from the original cell line, subject to certain restrictions and limited rights granted back to Catalent.

In consideration for the rights granted, Clade paid Catalent an upfront fee. We are also required to pay certain product-by-product milestone payments upon the achievement of certain development and regulatory milestones up to an aggregate of $16.2 million or $12.15 million depending on the product. We additionally agreed to pay royalties equal to a low single digit percentage of net sales of each product during a defined royalty term, after which royalty term the license automatically becomes fully paid-up, perpetual, irrevocable and royalty-free. We also agreed to pay annual minimum fees during a defined period, with milestone payments and royalties paid in a calendar year creditable against the annual minimum fees payable for the same calendar year.

The agreement remains in effect until terminated and may be terminated by us for convenience upon prior written notice or by either party for material breach, subject to specified cure periods. Certain provisions, including payment obligations, indemnification obligations and confidentiality obligations, survive termination. During the three months ended March 31, 2026 and 2025, no payments were made to Catalent.

Note 8—Leases

The Company has commitments under operating leases for certain facilities used in its operations. The Company maintains security deposits on certain leases in the amounts of $95 and $403 within security deposits and noncurrent assets in its consolidated balance sheets at March 31, 2026 and December 31, 2025, respectively. In September 2025, the Company executed a series of lease modifications with the same landlord that resulted in the early termination of its leases in Seattle, WA (“Seattle”) and Boston, MA (“Boston”). Concurrently, the Company entered into a new lease agreement in Watertown, MA (“Watertown”), set to begin upon the termination of the Boston lease. The Seattle lease is terminated on December 31, 2025, while the Boston lease is terminated on January 27, 2026, aligning with the commencement date of the Watertown lease. As a result of these lease modifications, the Company recorded a reduction of its right-of-use assets of $6,455 and lease liabilities totaling $7,850, which resulted in the recognition of a gain of $1,395 in the third quarter of 2025 related to the Seattle lease which had previously been impaired.

19

Table of Contents

The Watertown lease commenced on January 27, 2026 and the Company recognized $5,245 of right-of-use asset and lease liability, upon the commencement of the lease.

The Company’s leases have initial lease terms ranging from 5 to 16 years. Certain lease agreements contain provisions for future rent increases. Variable lease costs generally include common area maintenance and real estate taxes.

Following the reduction in force that occurred in July 2025, the Company is planning to sublease part of its Philadelphia, PA headquarters location. The Company evaluated the right-of-use asset for impairment as a result of this change in strategy and recorded an impairment charge of $6,763 during the third quarter of 2025.

Note 9—Income taxes

During the three months ended March 31, 2026 and 2025, the Company recorded no income tax benefits for the net operating losses incurred or for the research and development tax credits generated in the U.S. due to its uncertainty of realizing a benefit from those items.

The Company’s tax provision and the resulting effective tax rate for interim periods is determined based upon its estimated annual effective tax rate (“AETR”), adjusted for the effect of discrete items arising in that quarter. The impact of such inclusions could result in

a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings or losses versus annual projections. In each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual tax rate changes, a cumulative adjustment is made in that quarter.

The Company has evaluated the positive and negative evidence bearing upon its ability to realize its deferred tax assets, which primarily consist of net operating loss carryforwards. While the Company utilized a portion of its existing net operating loss carryforwards during tax year 2023, the Company has considered its history of cumulative net losses in the U.S., estimated future taxable income and prudent and feasible tax planning strategies and has concluded that it is more likely than not that the Company will not realize the benefits of its U.S. deferred tax assets. As a result, as of March 31, 2026, the Company has recorded a full valuation

21

allowance against its net deferred tax assets, exclusive of its deferred tax liability on in-process research and development (“IPR&D”) in the U.S.

Note 10—Basic and diluted net income (loss) per common share

The Company’s potentially dilutive securities, which include Restricted Stock Units (“RSUs”), restricted stock, warrants, early exercised stock options and stock options to purchase shares of the Company’s common stock, have been included in the computation of dilutive net income (loss) per share as applicable. The Company excluded the following potential shares of common stock presented based on amounts outstanding at each stated period end, from the computation of diluted net income (loss) per share for the three months ended March 31, 2026 and 2025 because including them would have had an anti-dilutive effect.

Note 11—Defined contribution plan

The Company has a 401(k) Employee Savings Plan (“401(k) Plan”) that is available to all employees of the Company. The Company has elected a Safe-Harbor provision for the 401(k) Plan in which participants are always fully vested in their employer contributions. The Company matches 100% of the first 3% of participating employee contributions and 50% of the next 2% of participating employee contributions. Contributions are made in cash. Contributions were approximately $240 and $397 for the three months ended March 31, 2026 and 2025 respectively. Such contribution expense has been recognized in the consolidated statement of operations for each period.

Note 12—Stock-based compensation

On June 17, 2021, the Company adopted the Century Therapeutics, Inc. 2021 Equity Incentive Plan (the “2021 Incentive Plan”) which superseded the 2018 Incentive Plan and from that date forward all issuances of incentive awards will be governed by the 2021 Incentive Plan.

The 2021 Incentive Plan provides for the Company to sell or issue common stock or restricted common stock, RSUs, or to grant incentive stock options or nonqualified stock options for the purchase of common stock, to employees, members of the Board of Directors, and consultants of the Company under terms and provisions established by the Board of Directors. Under the terms of the 2021 Incentive Plan, options may be granted at an exercise price not less than fair market value.

Upon adoption of the 2021 Incentive Plan, the Company was authorized to issue 5,481,735 shares of Common Stock under the 2021 Incentive Plan (which represents 5,640,711 shares of Common Stock initially available for grant under the 2021 Incentive Plan less 158,976 shares of Common Stock reserved for issuance upon the exercise of previously granted stock options that remain outstanding under the 2018 Incentive Plan). The number of shares of common stock initially reserved for issuance under the 2021 Incentive Plan shall be increased, upon approval by the Board of Directors, on January 1, 2022 and each January 1 thereafter, in an amount equal to the least of (i) five percent (5%) of the outstanding common stock on the immediately preceding December 31, or (ii) such number of common stock determined by the Board of Directors no later than the immediately preceding December 31. For 2026, the 2021 Incentive Plan reserved shares were increased under clause (i) by 4,375,955 shares, effective as of January 1, 2026. As of March 31, 2026, there were 3,950,926 shares available for issuance under the 2021 Incentive Plan.

Table of Contents

The Company’s stock-based awards are subject to service-based vesting conditions. Compensation expense related to awards to employees and directors with service-based vesting conditions is recognized on a straight-line basis based on the grant date fair value over the associated service period of the award, which is generally the vesting term. Stock awards granted typically vest over a four-year period but may be granted with different vesting terms. The Company may also issue awards with performance-based vesting conditions. For performance-based awards, the Company would reassess at each reporting date whether achievement of the performance condition is probable and accrue compensation expense if and when the achievement of the performance condition is probable.

The Company recognizes the costs of the stock-based compensation as the employees vest in the awards.

The weighted average grant date fair value of awards for options granted during the three months ended March 31, 2026 was $1.36. As of March 31, 2026, there was $6,540 of total unrecognized compensation expense related to unvested stock options with time-based vesting terms, which is expected to be recognized over a weighted average period of 3.10 years. The aggregate intrinsic value of options vested and exercisable as of March 31, 2026 and 2025 is calculated based on the difference between the exercise price and the fair value of our common stock. The intrinsic value of options exercised in 2026 and 2025 was $120 and $32, respectively.

The Company estimates the fair value of its option awards to employees and directors using Black-Scholes, which requires inputs and subjective assumptions, including (i) the expected stock price volatility, (ii) the calculation of the expected term of the award, (iii) the risk-free interest rate and (iv) expected dividends. Due to the lack of substantial company-specific historical and implied volatility data of its common stock, the Company has based its estimate of expected volatility on the historical volatility of a group of similar public companies. Starting in June of 2023, the Company had sufficient historical information regarding stock trading history, and started to use the Company’s own stock volatility. The Company has never paid dividends and does not expect to in the foreseeable future. The expected term of the options granted to employees is derived from the “simplified” method as described in Staff Accounting Bulletin 107 relating to stock-based compensation. The risk-free interest rates for periods within expected term of the option are based on the U.S. Treasury securities with a maturity date commensurate with the expected term of the associated award. The Company will account for actual forfeitures as they occur.

Employee Stock Purchase Plan

The ESPP was adopted by the Board of Directors in May 2021. A total of 564,071 shares of common stock were initially reserved for issuance under this plan, which shall be increased, upon approval by the Board of Directors, on January 1, 2022 and each January 1 thereafter, to the lesser of (i) one percent (1%) of the outstanding shares of common stock on the last day of the immediately preceding fiscal year, or (ii) an amount determined by the Board of Directors no later than the last day of the immediately preceding fiscal year. For 2022, the ESPP reserved shares were increased under clause (i) by 550,055 shares, effective as of January 1, 2022. For 2023, 2024, 2025 and 2026, the board waived the annual increase to the shares reserved under the ESPP. As of March 31, 2026, there were 579,499 shares available for issuance, under the ESPP.

Note 13Common Stock

At-The-Market

The Company has a Sales Agreement (“Sales Agreement”), with Cowen and Company, LLC, or (“Cowen”) to provide for the offering, issuance and sale of up to an aggregate amount of $150,000 of common stock from time to time in “at-the-market” offerings (the “ATM Program”). Shares of common stock pursuant to the ATM program were previously made pursuant to the Company’s shelf registration statement on Form S-3 (File No.333-265975) (the “Prior Shelf”). Upon the expiration of the Prior Shelf, the Company filed a new shelf registration statement on Form S-3 (No. 333-288616) (the “New Shelf”), which became effective in January 2026. The Company filed a prospectus supplement to the New Shelf for the ATM Program in March 2026. During the three months ended March 31, 2025, and March 31, 2026, the Company did not have any sales in the ATM Program.

Private Placement Offering

On January 7, 2026, the Company entered into a securities purchase agreement with certain institutional accredited investors (the “2026 Investors”), pursuant to which the Company issued and sold to the 2026 Investors in a private placement (the “2026 Private Placement”) (i) 92,030,595 shares of its common stock and accompanying warrants to purchase an aggregate of 58,695,648 shares of common stock (or pre-funded warrants in lieu thereof) and (ii) in lieu of common stock, to certain investors, pre-funded warrants to purchase an aggregate of up to 25,360,704 shares of its common stock and accompanying warrants to purchase 12,680,352 shares of common stock (or pre-funded warrants in lieu thereof), at an exercise price of $0.0001 per pre-funded warrant. The combined offering price of each share of common stock and accompanying common stock warrant was $1.15. The combined offering price of each pre-funded warrant and accompanying common stock warrant was $1.1499. The pre-funded warrants are exercisable immediately. Each common stock warrant has an exercise price per share of $2.60. The common stock warrants are exercisable from the date of issuance and will expire 30 days following the public announcement of initial Phase 1 clinical data for CNTY-813 or, if earlier, on the third anniversary of closing.

The 2026 Private Placement closed on January 9, 2026. The net proceeds received by the Company was approximately $126,400. The Company intends to use the net proceeds from the 2026 Private Placement to fund development of its lead product candidate, CNTY-813, and for working capital and other general corporate purposes.

The Company determined that each of the pre-funded warrants and common stock warrants are freestanding financial instruments that are legally detachable and separately exercisable from the common stock and from each other.

The Company evaluated both instruments under ASC 480, Distinguishing Liabilities from Equity, and concluded that neither represents an ASC 480 liability. Neither instrument (i) embodies an unconditional obligation to redeem by transferring assets, (ii) embodies an obligation to repurchase the Company's shares by transferring assets, or (iii) embodies an obligation settleable in a variable number of shares with a monetary value based predominantly on a fixed amount, variations in something other than the fair value of the Company's shares, or variations inversely related to the Company's share price.

The Company further evaluated whether the instruments meet the definition of a derivative under ASC 815. Both instruments meet the definition of a derivative; however, the Company concluded that they qualify for the scope exception in ASC 815-10-15-74(a) for contracts that are both indexed to the Company's own stock and classified in stockholders' equity. Under the two-step indexation framework in ASC 815-40-15, neither the exercise contingencies nor the settlement provisions preclude indexation. Under the equity classification guidance in ASC 815-40-25, both instruments meet all applicable conditions, including that settlement is in the Company's shares, the Company has sufficient authorized and unissued shares, and settlement is within the Company's control.

26

Table of Contents

Accordingly, both the pre-funded warrants and common stock warrants were classified as a component of permanent stockholders' equity within additional paid-in capital.

Note 14—Segment Reporting

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 (“CODM”) in making decisions on how to allocate resources and assess performance. The Company views its operations and manages the business as one operating segment. The Company’s CODM is its Chief Executive Officer. The CODM uses research and development expenses, general and administrative expenses, and net loss as measures of profit or loss to assess performance and allocate resources, all of which are presented on the face of the financial statements. The CODM also uses a further breakdown of research and development expenses to assess performance and allocate resources as presented below:

Overview

We are a biotechnology company harnessing the power of allogeneic pluripotent stem cell therapies to develop potentially curative cell therapy products for autoimmune diseases, including type 1 diabetes, or T1D, and cancer. Our islet, T cell and NK cell programs are allogeneic, meaning they are derived from healthy donors for use in any patient, rather than being sourced from an individual for their own specific use, as is the case with autologous T cells. As a result, we believe such “off-the-shelf" therapies have the potential to overcome the limitations of first-generation cell therapies by providing readily available treatments more quickly, reliably, at greater scale, and to a broader patient population. What we believe further sets us apart from other allogeneic approaches is our focus on induced pluripotent stem cells, or iPSCs, which possess the unique ability to self-renew indefinitely and differentiate into any cell type, enabling virtually unlimited genetic editing, consistent reproducibility, and scalable manufacturing. We have created a comprehensive, genetically engineered allogeneic cell therapy platform that includes:

Industry-leading iPSCs and differentiation know-how to generate fully functional mature cells from iPSCs, or iPSC-derived cells;
Clustered regularly interspaced short palindromic repeats, or CRISPR mediated precision gene editing that allows us to incorporate multiple transgenes and disrupt target genes intended to optimize cell product performance;
Our proprietary Allo-Evasion™ technology intended to prevent rejection of our cell products by the host immune system, enabling the potential for persistence and re-dosing of therapy; and
Cutting-edge manufacturing capabilities intended to drive scale advantages and reduce cost of goods sold, or COGs, while minimizing product development and supply risk.

We are leveraging our expertise in cellular reprogramming, differentiation, genetic engineering, and manufacturing to develop therapies with the potential to provide enhanced clinical outcomes compared to existing cell therapy technologies and available therapeutic options. We are unique in the breadth of cell types we can generate from iPSCs, including iPSC-derived islet cells, iPSC-derived CD4+ and CD8+

ab T cells,or ab iT cells, and iPSC- natural killer cells, or iNK cells. We believe this capability enables optimal matching of cell characteristics to disease indication, ensuring we target the right cell for the right indication.

Our vision is to become a premier, fully integrated biotechnology company by developing and ultimately commercializing off-the-shelf allogeneic cell therapies that dramatically and positively transform the lives of patients suffering from life-threatening autoimmune diseases and cancers. To achieve our vision, our world-class team is applying its decades of collective experience in cell therapy and drug development, manufacturing, and commercialization.

In November 2025, we announced our plans to develop an iPSC-derived islet program, CNTY-813, for T1D. We are leveraging our deep expertise in selective iPSC differentiation to advance this program, engineered with Allo-Evasion™ 5.0, toward clinical evaluation subject to regulatory clearance. We have advanced CNTY-813 into IND-enabling studies and expect to submit an IND in the fourth quarter of 2026.

28

Table of Contents

We also continue to make progress with IND-enabling studies for CNTY-308, a CD19-targeted CD4+/CD8+ ab CAR-iT cell therapy functionally comparable to primary T cells and engineered with Allo-Evasion™ 5.0. CNTY-308 is being developed as a potential treatment for B-cell-mediated diseases. Following successful completion of these IND-enabling studies, and the receipt of requisite regulatory approval, we expect to initiate clinical studies in 2026.

In November 2025, we announced that we will prioritize clinical development activities for CNTY-101, a CAR-iNK cell therapy with six precision gene edits, in CARAMEL, a Phase 1/2 investigator sponsored trial, or IST, which is currently enrolling and dosing patients living with B-cell-mediated autoimmune diseases, led by Professors Georg Schett and Andreas Mackensen and is sponsored by the Friedrich-Alexander University Erlangen-Nürnberg. Accordingly, we discontinued our company-sponsored clinical activities under the CALiPSO-1 trial and will redirect these resources to other programs. Investigators of the CARAMEL IST presented initial data in December 2025.

In January 2026, we entered into a securities purchase agreement with the 2026 Investors in connection with the 2026 Private Placement.

Based on our current business plans, we believe our cash, cash equivalents and investments as of March 31, 2026 of $217.0 million will be sufficient for us to fund our operating expenses and capital expenditures requirements into the first quarter of 2029. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. We anticipate that our expenses and operating losses will increase substantially over the foreseeable future. The expected increase in expenses will be driven in large part by our ongoing activities, if and as we:

continue to advance our iPSC cell therapy platforms;
progress preclinical and clinical development of our product candidates;
seek to discover and develop additional product candidates;
expand and validate our own clinical-scale cGMP facilities;
seek regulatory approvals for any of our product candidates that successfully complete clinical trials;
maintain, expand, protect, and enforce our intellectual property portfolio;
continue to incur costs associated with operating as a public company;
acquire or in-license other product candidates and technologies;
incur additional costs associated with operating as a public company, which will require us to add operational, financial and management information systems and personnel, including personnel to support our drug development and any future commercialization efforts; and
increase our employee headcount and related expenses to support these activities.

29

Table of Contents

We are also investing in building our capabilities in key areas of manufacturing sciences and operations, including development of our iPSC cell therapy platforms, product characterization, and process analytics from the time product candidates are in early research phases. Our investments also include scaled research solutions, scaled infrastructure, and novel technologies intended to improve efficiency, characterization, and scalability of manufacturing.

We anticipate that we will need to raise additional financing in the future to fund our operations, including funding for preclinical studies, clinical trials and the commercialization of any approved product candidates. We intend to use the proceeds from such financings to, among other uses, fund research and development of our product candidates and development programs. Until such time, if ever, as we can generate significant product revenue, we expect to finance our operations with our existing cash, cash equivalents, and investments, any future equity or debt financings, and upfront and milestone and royalty payments, if any, received under future licenses or collaborations. We may not be able to raise additional capital on terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, results of operations, and financial condition would be adversely affected. Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability.

License and collaboration agreements

Bristol-Myers Squibb

On January 7, 2022, we entered into the Collaboration Agreement with Bristol-Myers Squibb to collaborate on the research, development and commercialization of induced pluripotent stem cell derived, engineered natural killer cell and/or gamma delta T cell programs for hematologic malignancies, initially focused on acute myeloid leukemia, and multiple myeloma.

Under the terms of the Collaboration Agreement, Bristol-Myers Squibb made a non-refundable, upfront cash payment of $100.0 million and purchased 2,160,760 shares of our common stock at a price per share of $23.14, for an aggregate purchase price of $50.0 million.

Following an internal corporate portfolio prioritization process, Bristol-Myers Squibb notified the Company on December 12, 2024 that it would be terminating the Collaboration Agreement in its entirety without cause. The termination was effective as of March 12, 2025.

Fujifilm Cellular Dynamics, Inc.

On September 18, 2018, we entered into the Differentiation License with FCDI. The Differentiation License, as amended, provides us with an exclusive license under certain patents and know-how related to human iPSC consisting of cells that are or are modifications of NK cells, T cells, dendritic cells and macrophages derived from human iPSC. In consideration for the Differentiation License, FCDI received 2,980,803 shares of common stock.

Also on September 18, 2018, we entered into the Reprogramming License with FCDI. The Reprogramming License, as amended, provides us with a non-exclusive license under certain patents and know-how related to the reprogramming of human somatic cells to iPSCs and provide us access to iPSC lines for clinical use. Under the Reprogramming License, we are required to make certain developmental and regulatory milestone payments as well as royalty payments upon commercialization in the low single digits. In connection with the Reprogramming License, we entered into the FCDI Collaboration Agreement with FCDI on October 21, 2019, pursuant to which we agreed to fund research and development work at FCDI pursuant to a research plan.

30

Table of Contents

Under the FCDI Collaboration Agreement, FCDI provides certain services to us to develop and manufacture iPSCs and immune cells derived therefrom. Under the terms of the FCDI Collaboration Agreement, as amended, FCDI will provide services in accordance with the approved research plan and related research budget. The initial research plan covers the period from the date of execution of the FCDI Collaboration Agreement through March 31, 2022. On July 29, 2022 we amended the FCDI Collaboration Agreement to extend the term through September 30, 2025.

On January 7, 2022, we and FCDI entered into the Letter Agreement, which amends each of the FCDI Agreements. Pursuant to the Letter Agreement, and in consideration for amending the FCDI Agreements, we agreed to pay to FCDI (i) an upfront payment of $10.0 million, (ii) a percentage of any milestone payments received by us under the FCDI Collaboration Agreement, in respect of achievement of development or regulatory milestones specific to Japan, and (iii) a percentage of all royalties received by us under the FCDI Collaboration Agreement in respect of sales of products in Japan.

On September 22, 2023, we entered into the Autoimmune License with FCDI, whereby FCDI will grant non-exclusive licenses to us for certain patent rights and know-how related to cell differentiation and reprogramming for the development and commercialization of iPSC-derived therapies for the treatment of inflammatory and autoimmune diseases. Under the terms of the Autoimmune License, FCDI will be eligible to receive certain development and regulatory milestone payments as well as low single-digit royalties related to products developed in connection with the Autoimmune License. In addition, on September 22, 2023, we and FCDI amended the Reprogramming License, Differentiation License and the FCDI Collaboration Agreement to expand our existing license related to the development and commercialization of iPSC-derived cancer immunotherapeutic to also include inflammatory and autoimmune diseases.

During the three months ended March 31, 2026 and 2025, we made payments of $0 and $1.5 million and incurred research and development expenses of $0 and $1.5 million, in-process research and development expenses of $0 and $0.5 million and legal fees of $0 million and $0.1 million, respectively, related to the FCDI Agreements. The legal fees are recorded within general and administrative expenses in the consolidated statements of operations and comprehensive loss.

iCELL Inc. and Distributed Bio, Inc.

We also have entered into a sublicense agreement with iCELL and a master services agreement with DBio. See “Note 7—Commitments and contingencies” to our consolidated financial statements.

Catalent Dusseldorf GmbH

On December 12, 2022, Clade entered into a non-exclusive license agreement with Catalent, which was subsequently amended in March 2026, pursuant to which Catalent granted Clade a worldwide, non-exclusive, non-transferrable, royalty-bearing license under all rights owned or controlled by Catalent to one of its GMP-grade iPSC cell lines derived from human cord blood CD34+ cells, to develop, have developed, make, have made, use, have used, sell, offer for sale, have sold, distribute, have distributed, import, have imported and otherwise exploit or have exploited cell therapy products. The license (as amended, the “Catalent License”), permits the genetic modification of the licensed cell line and the development and commercialization of resulting cell therapy products for any indication. We have a right to use the Catalent License as a result of our acquisition of Clade.

Under the Catalent License, we may grant sublicenses to third parties to develop, manufacture and commercialize resulting products, but we may not sublicense the original cell line itself. Catalent retains ownership of the original cell line, and we own the modified cells and resulting products that we make from the original cell line, subject to certain restrictions and limited rights granted back to Catalent.

31

Table of Contents

In consideration for the rights granted, Clade paid Catalent an upfront fee. We are also required to pay certain product-by-product milestone payments upon the achievement of certain development and regulatory milestones up to an aggregate of $16.2 million or $12.15 million depending on the product. We additionally agreed to pay royalties equal to a low single digit percentage of net sales of each product during a defined royalty term, after which royalty term the license automatically becomes fully paid-up, perpetual, irrevocable and royalty-free. We also agreed to pay annual minimum fees during a defined period, with milestone payments and royalties paid in a calendar year creditable against the annual minimum fees payable for the same calendar year.

The agreement remains in effect until terminated and may be terminated by us for convenience upon prior written notice or by either party for material breach, subject to specified cure periods. Certain provisions, including payment obligations, indemnification obligations and confidentiality obligations, survive termination.

Components of operating results

Collaboration revenue

We have not generated any revenue from product sales and do not expect to generate any revenue from the sale of products for the foreseeable future. Our revenues to date were generated through our collaboration, option and license agreement with Bristol-Myers Squibb, which was terminated in March 2025. We recognized revenue over the expected performance period under this agreement. We expect that our revenue for the next several years will be derived primarily from any collaborations that we may enter into in the future. To date, we have not received any royalties under any of our existing and former collaboration agreements.

Operating expenses

Research and development

To date, research and development expenses have related primarily to the discovery and development of our iPSC cell therapy platform technology and product candidates and acquired in-process research and development. Research and development expenses are recognized as incurred and payments made prior to the receipt of goods or services to be used in research and development are recorded as prepaid expenses until the goods or services are received.

Research and development expenses consist of personnel-related costs, including salaries, and benefits, stock compensation expense, external research and development expenses incurred under arrangements with third parties, laboratory supplies, costs to acquire and license technologies facility and other allocated expenses, including rent, depreciation, and allocated overhead costs, and other research and development expenses.

We deploy our employee and infrastructure resources across multiple research and development programs for developing our iPSC cell therapy platforms, identifying and developing product candidates, and establishing manufacturing capabilities. Due to the number of ongoing projects and our ability to use resources across several projects, the vast majority of our research and development costs are not recorded on a program-specific basis. These include costs for personnel, laboratory, and other indirect facility and operating costs.

Research and development activities account for a significant portion of our operating expenses. We anticipate that our research and development expenses will increase for the foreseeable future as we expand our research and development efforts including expanding the capabilities of our iPSC cell therapy platforms, identifying product candidates, progressing preclinical studies and clinical trials, including for our first clinical product candidate CNTY-101, seeking regulatory approval of our product candidates, and incurring costs to acquire and license technologies aligned with our goal of translating iPSCs to therapies. A change in the outcome of any of these variables could mean a significant change in the costs and timing associated with the development of our product candidates.

Table of Contents

General and administrative

General and administrative expenses consist of personnel-related costs, including salaries, benefits, and non-cash stock-based compensation, for our employees in executive, legal, finance, human resources, information technology, and other administrative functions, legal fees, consulting fees, recruiting costs, and facility costs not otherwise included in research and development expenses. Legal fees include those related to corporate and patent matters.

Impairment of long-lived assets

We review our amortizable long lived assets, consisting primarily of our lease related right of use assets and property and equipment, when impairment indicators are present by comparing the carrying values of the assets with their estimated future undiscounted cash flows. Should the carrying value of the long lived assets exceed the undiscounted cash flows, the Company calculates the fair value of the underlying long lived assets, utilizing a discounted cash flow approach, which is considered a level three fair value estimate.

We incurred no impairment expense during the three months ended March 31, 2026 and 2025.

Interest income

Interest income consists of interest earned on our cash, cash equivalents and investment balances.

Income taxes

Due to historical losses, we maintain a full valuation allowance against the unrealizable portion of our deferred tax assets.

Collaboration revenue

During the three months ended March 31, 2026 and 2025, we recognized revenue of $0 million and $109.2 million under our collaboration agreement with Bristol-Myers Squibb, respectively. See “Note 6—Bristol-Myers Squibb collaboration” to our consolidated financial statements for additional information. The Collaboration Agreement was terminated, effective as of March 12, 2025. As such, we recognized the remaining transaction price of $109.2 million as collaboration revenue during the three months ended March 31, 2025. There will be no future collaboration revenues recognized under this collaboration agreement.

Research and development expenses were $17.1 million and $26.6 million for the three months ended March 31, 2026 and 2025, respectively. The decrease of $9.5 million was primarily due to:

a decrease in personnel and related costs of $4.4 million due to a reduction in research and development staff.
a decrease in facility and other allocated costs of $1.9 million primarily due to a decrease in facility and other allocated costs due to the portfolio prioritization announced in the third quarter of 2025.
a decrease in research and laboratory expenses of $2 million primarily due to reduced spending on clinical trial related expenses for CNTY-101.

General and administrative expenses

General and administrative expenses were $6.6 million and $8.4 million for the three months ended March 31, 2026 and 2025, respectively. This decrease was primarily due to a reduction in personnel, and remeasurement of the contingent consideration liability offset by an increase in facility and other allocated costs due to the portfolio prioritization announced in the third quarter of 2025.

Interest income

Interest income was $2.0 million and $2.4 million for the three months ended March 31, 2026 and 2025, respectively, which related to interest earned on our cash, cash equivalents, and investment balances.

Liquidity, capital resources, and capital requirements

Sources of liquidity

To date, we have funded our operations from the issuance and sale of our equity securities, debt financing and collaboration revenues. Since our inception, we have raised approximately $792 million in net proceeds from the sales of our equity securities. As of March 31, 2026, we had cash, and cash equivalents of $51.0 million and investments of $165.9 million. Based on our research and development plans, we believe our existing cash, cash equivalents and investments, will be sufficient to fund our operating expenses and capital expenditures requirements into the first quarter of 2029. Since our inception, we have incurred significant operating losses. We have not yet commercialized any products and we do not expect to generate revenue from sales of any product candidates for a number of years, if ever. We had an accumulated deficit of $813.6 million as of March 31, 2026.

In July 2022, we entered into a Sales Agreement with Cowen under which we may offer and sell, from time to time in our sole discretion, shares of our common stock, having an aggregate offering price of up to $150 million through Cowen as sales agent. In February of 2024, 4,084,502 shares of common stock were issued and sold pursuant to the Sales Agreement at a weighted-average price of $4.50 per share, resulting in approximately $18.4 million in gross proceeds.

In April 2024, we entered into a securities purchase agreement or, the Securities Purchase Agreement, with certain institutional accredited investors, or the Investors, pursuant to which we agreed to issue and sell to the Investors in a private placement an aggregate of 15,873,011 shares of common stock, or the Private Placement Shares, at a price of $3.78 per share, or the Private Placement. We received aggregate gross proceeds from the Private Placement of approximately $60 million, before deducting placement agent fees and offering expenses.

In January 2026, we entered into a securities purchase agreement with certain institutional accredited investors (the “2026 Investors”), pursuant to which we issued and sold to the 2026 Investors in a private placement (the “2026 Private Placement”) (i) 92,030,595 shares of its common stock and accompanying warrants to purchase an aggregate of 58,695,648 shares of common stock (or pre-funded warrants in lieu thereof) and (ii) in lieu of common stock, to certain investors, pre-funded warrants to purchase an aggregate of up to 25,360,704 shares of its common stock and accompanying warrants to purchase 12,680,352 shares of common stock (or pre-funded warrants in lieu thereof), at an exercise price of $0.0001 per pre-funded warrant. The combined offering price of each share of common stock and accompanying common stock warrant was $1.15. The combined offering price of each pre-funded warrant and accompanying common stock warrant was $1.1499. The pre-funded warrants are exercisable immediately. Each common stock warrant has an exercise price per share of $2.60. The common stock warrants are exercisable from the date of issuance and will expire 30 days following the public announcement of initial Phase 1 clinical data for CNTY-813 or, if earlier, on the third anniversary of closing. Aggregate gross proceeds were $135.0 million before deducting placement agent fees and offering expenses.

Future funding requirements

We expect to incur additional losses in the foreseeable future as we conduct and expand our research and development efforts, including conducting preclinical studies and clinical trials, developing new product candidates, establishing internal and external manufacturing capabilities, and funding our operations generally. We anticipate that we will need to raise additional financing in the future to fund our operations, including the commercialization of any approved product candidates. We are subject to the risks typically related to the development of new products, and we may encounter unforeseen expenses, difficulties, complications, delays, and other unknown factors that may adversely affect our business.

35

Table of Contents

Our future capital requirements will depend on many factors, including:

the scope, timing, progress, costs, and results of discovery, preclinical development, and clinical trials for our current and future product candidates;
the number of clinical trials required for regulatory approval of our current and future product candidates;
the costs, timing, and outcome of regulatory review of any of our current and future product candidates;
the cost of manufacturing clinical and commercial supplies of our current and future product candidates;
the costs and timing of future commercialization activities, including manufacturing, marketing, sales, and distribution, for any of our product candidates for which we receive marketing approval;
the costs and timing of preparing, filing, and prosecuting patent applications, obtaining, maintaining, protecting, and enforcing our intellectual property rights, and defending any intellectual property-related claims, including any claims by third parties that we are infringing upon, misappropriating, or violating their intellectual property rights;
our ability to maintain existing, and establish new, strategic collaborations, licensing, or other arrangements and the financial terms of any such agreements, including the timing and amount of any future milestone, royalty, or other payments due under any such agreement;
the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval;
expenses to attract, hire and retain, skilled personnel;
costs of operating as a public company;
our ability to establish a commercially viable pricing structure and obtain approval for coverage and adequate reimbursement from third-party and government payors;
the effect of competing technological and market developments; and
the extent to which we acquire or invest in businesses, products, and technologies.

36

Table of Contents

Until and unless we can generate substantial product revenue, we expect to finance our cash needs through the proceeds from a combination of equity offerings and debt financings, and potentially through additional license and development agreements or strategic partnerships or collaborations with third parties. Financing may not be available in sufficient amounts or on reasonable terms. In addition, market volatility resulting from the effects of pandemics, inflationary pressures, disruptions of financial institutions, political unrest and hostilities, war or other factors could adversely impact our ability to access capital as and when needed. We have no commitments for any additional financing and will likely be required to raise such financing through the sale of additional securities, which, in the case of equity securities, may occur at prices lower than the offering price of our common stock. If we sell equity or equity-linked securities, our current stockholders, may be diluted, and the terms may include liquidation or other preferences that are senior to or otherwise adversely affect the rights of our stockholders. Moreover, if we issue debt, we may need to dedicate a substantial portion of our operating cash flow to paying principal and interest on such debt and we may need to comply with operating restrictions, such as limitations on incurring additional debt, which could impair our ability to acquire, sell or license intellectual property rights which could impede our ability to conduct our business.

Operating activities

Net cash used in operating activities was $25.3 million and $34.6 million for the three months ended March 31, 2026 and 2025, respectively. Net cash used in operating activities during the three months ended March 31, 2026 consisted primarily of our net loss of $21.6 million offset by non-cash charges of $2.8 million and a decrease of $6.4 million in our net operating assets and liabilities. The non-cash charges of $2.8 million consisted primarily of $3 million for depreciation expense, non-cash operating lease expense of $0.4 million, and stock-based compensation expense of $1.4 million, partially offset by gain on remeasurement of contingent consideration liability of $1.8 million, and amortization of marketable securities of $0.2 million. The change in operating assets and liabilities was primarily due to a $0.8 million decrease in operating lease liability, a $1.6 million decrease in accounts payable, and a $4 million decrease in accrued expenses.

Net cash used in operating activities during the three months ended March 31, 2025 consisted primarily of our net income of $76.5 million and a decrease of $116.2 million in our net operating assets and liabilities, partially offset by non-cash charges of $5.0 million. The non-cash charges of $5.0 million consisted primarily of $3.2 million for depreciation expense, non-cash operating lease benefit of $0.5 million, a decrease in lease liability due to a lease termination, and stock-based compensation expense of $2.4 million, partially offset by amortization of marketable securities of $0.9 million and gain on contingent consideration liability of $0.2 million. The change in operating assets and liabilities was primarily due to a $1.2 million decrease in operating lease liability, a $109.2 million decrease in deferred revenue due to the termination of the Collaboration Agreement with Bristol-Myers Squibb, and a $6.5 million decrease in accrued expenses.

Payment obligations under our license, collaboration, and acquisition and merger agreements as of March 31, 2026 are contingent upon future events such as our achievement of pre-specified development, regulatory, and commercial milestones, or royalties on net product sales. As of March 31, 2026, the timing and likelihood of achieving the milestones and success payments and generating future product sales are uncertain and therefore, any related payments are not included in the table above. We also enter into agreements in the normal course of business for sponsored research, preclinical studies, contract manufacturing, and other services and products for operating purposes, which are generally cancelable upon written notice. These obligations and commitments are not included in the table above. See Note 7 “Commitments and contingencies” for additional information.

We have commitments under operating leases for certain facilities used in our operations.

JOBS Act accounting election

As a company with less than $1.235 billion in revenue during our last fiscal year, we qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. An emerging growth company may take advantage of specified reduced reporting requirements that are otherwise generally applicable to public companies. As such, we may take advantage of reduced disclosure and other requirements otherwise generally applicable to public companies, including:

not being required to have our registered independent public accounting firm attest to management’s assessment of our internal control over financial reporting;

38

Table of Contents

presenting reduced disclosure about our executive compensation arrangements;
an exemption from compliance with any requirement that the Public Company Accounting Oversight Board may adopt regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;
not being required to hold non-binding advisory votes on executive compensation or golden parachute arrangements; and,
extended transition periods for complying with new or revised accounting standards.

The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This provision allows an emerging growth company to delay the adoption of some accounting standards until those standards would otherwise apply to private companies. We have elected to use the extended transition period to enable us to comply with new or revised accounting standards and, therefore, we will adopt new or revised accounting standards at the time private companies adopt the new or revised accounting standard and will do so until such time that we either (i) irrevocably elect to “opt out” of such extended transition period or (ii) no longer qualify as an emerging growth company.

We will remain an emerging growth company until the earliest of (i) December 31, 2026, (ii) the last day of the fiscal year in which we have total annual gross revenue of at least $1.235 billion, (iii) the last day of the fiscal year in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

We are also a “smaller reporting company,” meaning that the market value of our stock held by non-affiliates is less than $700.0 million and our annual revenue is less than $100.0 million during the most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250.0 million or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700.0 million as of the last business day of the second fiscal quarter of such year. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

Critical accounting policies and significant judgments and estimates

Refer to Note 2, Summary of Significant Accounting Policies, included in Part I, Item 1 of this Quarterly Report on Form 10-Q for a discussion of our critical accounting policies.

During the three months ended March 31, 2026, there were no material changes to our critical accounting policies from those described in our audited financial statements for the year ended December 31, 2025 included in our Annual Report on Form 10-K filed with the SEC on March 12, 2026, except as noted above.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate sensitivities. We do not currently have any material exposure to foreign currency fluctuations and do not engage in any hedging activities as part of our normal course of business.

39

Table of Contents

Interest rate risk

We had cash, cash equivalents, and restricted cash of $53.8 million as of March 31, 2026, which consisted of bank deposits and money market funds. We also had investments of $165.9 million as of March 31, 2026. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. However, because of the low risk profile of the instruments in our portfolio, a change in market interest rates would not have a material impact on our financial condition and/or results of operations.

Banking Instability

Future disruptions of financial institutions where we bank or have credit arrangements, or disruptions of the financial services industry in general, could adversely affect our ability to access our cash and cash equivalents.

Effects of Inflation

Inflation generally affects us by increasing our cost of labor and laboratory consumables. We believe that inflation has not had a material effect on our financial statements.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosures controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of March 31, 2026. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2026, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Control over Financial Reporting

Management determined that, as of March 31, 2026, there were no changes in our internal control over financial reporting that occurred during the three months then ended that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. Our management believes that there are currently no claims or actions pending against us, the ultimate disposition of which would have a material adverse effect on our results of operations, financial condition or cash flows.

Item 1A. Risk Factors

There have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025.

FAQ

How did Century Therapeutics (IPSC) perform financially in Q1 2026?

Century Therapeutics reported a net loss of $21.6 million for Q1 2026. This compares to net income of $76.6 million in Q1 2025, when results included significant one-time collaboration revenue. Operating expenses declined year over year as the company streamlined spending.

Why did Century Therapeutics’ revenue drop in the first quarter of 2026?

Quarterly revenue fell because collaboration revenue was $0 in Q1 2026, versus $109.2 million in Q1 2025. The prior year benefited from revenue recognition tied to the now-terminated Bristol-Myers Squibb collaboration, which no longer contributes to Century Therapeutics’ top line.

What is Century Therapeutics’ cash position and runway as of March 31, 2026?

As of March 31, 2026, Century Therapeutics held about $217.0 million in cash, cash equivalents and investments. Management believes this balance will fund operating expenses and capital needs into the first quarter of 2029, supporting ongoing preclinical and early clinical development.

How much did Century Therapeutics raise in its January 2026 private placement?

Century Therapeutics raised approximately $126.4 million in net proceeds from a January 2026 private placement. The deal included 92.0 million common shares plus pre-funded and common stock warrants, significantly increasing share count to support development of lead iPSC-derived cell therapy programs.

What are Century Therapeutics’ lead pipeline programs mentioned in the Q1 2026 report?
