of Changes in Redeemable Noncontrolling Interest and Stockholders’ Deficit for the three and six months ended June 30, 2025 and 2024 and Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2025 and 2024 are unaudited. These unaudited financial statements have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.

The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) necessary to state fairly the Company’s financial position as of June 30, 2025, the results of operations for the three and six months ended June 30, 2025 and 2024 and cash flows for the six months ended June 30, 2025 and 2024. Certain prior year amounts have been reclassified to conform to the current year presentation. The December 31, 2024 Condensed Consolidated Balance Sheet included herein was derived from the audited financial statements but does not include all disclosures or notes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the audited financial statements and the accompanying notes for the year ended December 31, 2024, contained in the Company’s Annual Report on Form 10-K filed with the SEC on March 17, 2025.

Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). These unaudited consolidated financial statements are presented in U.S. Dollars.

Interim results are not necessarily indicative of results for an entire year.

Use of Estimates

The preparation of unaudited condensed consolidated financial statements, in accordance with GAAP, requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the condensed consolidated financial statements, and the amounts of expenses during the reported periods. Certain estimates in these condensed consolidated financial statements have been made in connection with the calculation of research and development expenses, equity-based compensation expense and the provision for or benefit from income taxes. The Company bases its estimates on historical experience and various other assumptions, including in certain circumstances future projections, which management believes to be reasonable under the circumstances. Actual results could differ from those estimates. Changes in estimates are reflected in reported results in the period in which they become known.

Cash Equivalents and Marketable Securities

The Company considers all highly liquid investments with an original maturity of 90 days or less on the date of purchase to be cash equivalents. The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these items.

The Company’s investments in marketable debt securities have been classified and accounted for as available-for-sale. The Company classifies its marketable debt securities as short-term due to its availability for use in its current operations. The cost of securities sold is determined using the specific identification method.

The Company considers all available evidence to evaluate if a credit loss exists, and if so, recognizes an allowance for credit loss.

Accrued Expenses

Accrued expenses as presented in the Condensed Consolidated Balance Sheets as of June 30, 2025 and December 31, 2024 consisted of the following (in thousands):


	June 30, 2025		December 31, 2024
Compensation	$	7,233	$	10,217
Severance		663		1,236
Clinical study related costs		13,576		16,452
Facility related costs		871		369
Accrued legal costs		1,068		395
Accrued consulting and professional fees		297		557
Other accrued expenses		1,208		1,911
Total accrued expenses and other	$	24,916	$	31,137

Research and Development Costs

Research and development costs are expensed as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries, benefits, third party license fees, and external costs of outside vendors engaged to conduct manufacturing and preclinical development activities and clinical trials.

The Company records accruals based on estimates of services received, efforts expended, and amounts owed pursuant to contracts with numerous contract research organizations. In the normal course of business, the Company contracts with third parties to perform various clinical study activities in the ongoing development of potential products. The financial terms of these agreements are subject to negotiation and variation from contract to contract and may result in uneven payment flows. Payments under the contracts depend on factors such as the achievement of certain events and the completion of portions of the clinical study or similar conditions. The objective of the Company’s accrual policy is to match the recording of expenses in its financial statements to the actual services received and efforts expended. As such, expense accruals related to clinical studies are recognized based on the company’s estimate of the degree of completion of the event or events specified in the specific clinical study.

The Company records nonrefundable advance payments it makes for future research and development activities as prepaid expenses. Prepaid expenses are recognized as expense in the Condensed Consolidated Statement of Operations and Comprehensive Loss as the Company receives the related goods or services.

Costs incurred in obtaining technology licenses are charged to research and development expense as purchased in-process research and development if the technology licensed has not reached technological feasibility and has no alternative future use.

Fixed Assets

Fixed assets are stated at cost, less accumulated depreciation. Generally, expenditures for maintenance and repairs are charged to expense and major improvements or replacements are capitalized. The Company computes depreciation and amortization using the straight-line method over the estimated useful life of the asset. Leasehold improvements are amortized over the lesser of the life of the lease or the estimated useful life of the leasehold improvement. The estimated useful lives are as follows:


Buildings	25-30 years
Computer equipment and software	3-5 years
Furniture and equipment	5-7 years
Leasehold improvements	remainder of lease term

Fixed assets consisted of the following (in thousands):


	June 30, 2025			December 31, 2024
Land	$	1,405		$	1,405
Buildings		21,095			21,095
Leasehold improvements		22,263			21,822
Furniture and equipment		6,678			5,647
Computer equipment and software		1,431			838
Construction in progress		4,534			2,447
Less: accumulated depreciation		(13,881	)		(11,032	)
Total fixed assets, net	$	43,525		$	42,222

Depreciation expense for the three months ended June 30, 2025 and 2024 was $1,491,000 and $964,000, respectively. Depreciation expense for the six months ended June 30, 2025 and 2024 was $2,875,000 and $1,797,000, respectively

Impairment of Long-Lived Assets and Assets Held for Sale

Long-lived assets such as fixed assets and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset.

The Company’s real property in Greensboro, North Carolina continues to meet the criteria for held-for-sale accounting. The carrying value of this asset has been reflected as a component of total current assets in the accompanying Condensed Consolidated Balance Sheets as of June 30, 2025 and December 31, 2024.

No impairment charges were recorded for the three or six months ended June 30, 2025 or 2024.

Income Taxes

The Company uses the liability method in accounting for income taxes as required by ASC Topic 740 — Income Taxes, under which deferred tax assets and liabilities are recorded for the future tax consequences attributable to the differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, available taxes in the carryback periods, projected future taxable income and tax planning strategies in making this assessment. Accordingly, the Company has provided a full valuation allowance to offset the net deferred tax assets at June 30, 2025 and December 31, 2024.

Interest and penalties related to income taxes are included in the expense for income taxes in the Company’s Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company has not incurred any significant interest or penalties related to income taxes in any of the periods presented.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy that prioritizes the inputs used to measure fair value is described below. The three levels of inputs used to measure fair value are as follows:

•

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities

•

Level 2 – Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable through correlation with market data

•

Level 3 – Unobservable inputs that are supported by little or no market data, which require the reporting entity to develop its own assumptions

For assets and liabilities recorded at fair value, it is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy. Fair value measurements for assets and liabilities where there exists limited or no observable market data are based primarily upon estimates and are often calculated based on the economic and competitive environment, the characteristics of the asset or liability and other factors. Therefore, fair value measurements cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset or liability. Additionally, there may be inherent weaknesses in any calculation technique and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the calculated current or future fair values. The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.

The carrying values of cash equivalents, accounts payable, and accrued liabilities approximate fair value due to the short term nature of these instruments.

Leases

The Company determines if an arrangement is a lease at inception. Balances recognized related to the Company’s operating and finance leases are included in right-of-use assets, net and lease liabilities in the Condensed Consolidated Balance Sheets. Right of use assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Lease terms may include options to extend or terminate the lease if it is reasonably certain that the Company will exercise the option. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. The right of use asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. The Company has elected a practical expedient to not separate its lease and non-lease components and instead account for them as a single lease component. Leases with a term of 12 months or less are not recorded on the balance sheet.

Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Lease payments for short-term leases are recorded to operating expense on a straight-line basis and variable lease payments are recorded in the period in which the obligation for those payments is incurred.

The grant date fair value of time and performance-based stock option awards is estimated using the Black-Scholes option pricing formula. Due to the lack of sufficient historical trading information with respect to its own shares, the Company estimates expected volatility based on the volatility of its own Class A common stock as well as a portfolio of selected stocks of companies believed to have market and economic characteristics similar to its own. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. Due to a lack of historical exercise data, the Company estimates the expected life of its outstanding stock options using the simplified method specified under Staff Accounting Bulletin Topic 14.D.2.
