Jade Biosciences, Inc.

1. Nature of the Business and Basis of Presentation

Background and Basis of Presentation

Jade Biosciences, Inc. (“Jade” or the “Company”), formerly known as Aerovate Therapeutics, Inc., is the resulting company of the Merger and Redomestication discussed below. Prior to the Merger and Redomestication, the private corporation Jade Biosciences, Inc. (“Pre-Merger Jade”) was established and incorporated under the laws of the state of Delaware on June 18, 2024 (referred to in these notes as the inception of the Company). Jade is focused on developing best-in-class therapies to address critical unmet needs in autoimmune diseases. Its lead candidate, JADE101, targets the cytokine called“A PRoliferation Inducing Ligand” (“APRIL”) for the treatment of immunoglobulin A nephropathy. Jade’s pipeline also includes two undisclosed antibody discovery programs, JADE-002 and JADE-003, which are currently in preclinical development. Jade has nominated a development candidate for the JADE-002 program, referred to as JADE201. Jade was launched based on assets licensed from Paragon Therapeutics Inc. (“Paragon”), an antibody discovery engine founded by healthcare investor Fairmount Funds Management LLC (“Fairmount”).

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of its financial position as of June 30, 2025, its results of operations for the three and six months ended June 30, 2025 and for the period from June 18, 2024 (inception) through June 30, 2024 and cash flows for the six months ended June 30, 2025 and for the period from June 18, 2024 (inception) through June 30, 2024. The condensed consolidated balance sheet at December 31, 2024 was derived from the audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. The accompanying condensed consolidated financial statements include accounts of the Company and its wholly owned subsidiaries, Jade Biosciences Canada ULC, Jade Biosciences MA Security Corporation, and Aerovate MA Securities Corporation. All intercompany amounts are eliminated in consolidation.

Reverse Recapitalization and Pre-Closing Financing

On April 28, 2025 (the “Closing Date”), the Company consummated the previously announced transaction (the “Closing”) pursuant to that certain Agreement and Plan of Merger and Reorganization, dated as of October 30, 2024, (the “Merger Agreement”) by and among Pre-Merger Jade, Aerovate Therapeutics, Inc., a Delaware corporation (“Aerovate”), Caribbean Merger Sub I, Inc., a Delaware corporation and wholly-owned subsidiary of Aerovate (“First Merger Sub”), and Caribbean Merger Sub II, LLC, a Delaware limited liability company and wholly-owned subsidiary of Aerovate (“Second Merger Sub”). As part of the Closing, First Merger Sub merged with and into Pre-Merger Jade, with Pre-Merger Jade continuing as a wholly owned subsidiary of Aerovate and the surviving corporation of the merger (the “First Merger” and such time, the “First Effective Time”), and Pre-Merger Jade merged with and into Second Merger Sub, with Second Merger Sub being the surviving entity of the merger (the “Second Merger” and, together with the First Merger, the “Merger”). In connection with the Merger, Second Merger Sub changed its name to “Jade Biosciences, LLC” and Aerovate changed its name to “Jade Biosciences, Inc.” Subsequently, Jade Biosciences, LLC merged with and into Jade Biosciences, Inc. The combined company following the Merger is the “Company.” The Company is led by Pre-Merger Jade’s management team and focuses on developing differentiated biologic therapies for patients living with autoimmune diseases.

In accordance with an exchange ratio determined in accordance with the terms of the Merger Agreement (the “Exchange Ratio”), as a result of and upon the First Effective Time, (i) each then-outstanding share of common stock, par value $0.0001 per share, of Pre-Merger Jade (the “Pre-Merger Jade common stock”) (including shares of Pre-Merger Jade common stock issued in connection with the Pre-Closing Financing (as defined below)) immediately prior to the First Effective Time (excluding shares cancelled pursuant to the Merger Agreement and excluding dissenting shares) automatically converted into the right to receive a number of shares of common stock, par value $0.0001, of Aerovate (the “Company common stock” and prior to the effective time of the Merger, the “Aerovate common stock”) equal to the Exchange Ratio, (ii) each then-outstanding share of Series Seed Convertible Preferred Stock, par value $0.0001 per share, of Pre-Merger Jade (the “Pre-Merger Jade Series Seed Convertible Preferred Stock”) immediately prior to the First Effective Time (excluding shares cancelled pursuant to the Merger Agreement and excluding dissenting shares) automatically converted into the right to receive a number of shares of Series A Non-Voting Convertible Preferred Stock, par value $0.0001 per share, of Aerovate (the “Series A Preferred Stock”), which are each convertible into 1,000 shares of Company common stock, equal to the Exchange Ratio divided by 1,000, (iii) each then-outstanding option to purchase Pre-Merger Jade common stock was assumed by Aerovate and was converted into an option to purchase shares of Company common stock, subject to adjustment as set forth in the Merger Agreement, and (iv) each then-outstanding pre-funded warrant to purchase shares of Pre-Merger Jade common stock (including any pre-funded warrants to purchase shares of Pre-Merger Jade common stock issued in the Jade Pre-Closing Financing) was converted into a pre-funded warrant to purchase shares of Company common stock (subject to adjustment as set forth in the Merger Agreement and the form of pre-funded warrant).

The Exchange Ratio was calculated as 0.6311 shares of Aerovate common stock for each share of Pre-Merger Jade common stock (and 0.0006311 shares of Series A Preferred Stock for each share of Pre-Merger Jade Series Seed Convertible Preferred Stock) on the Closing Date, which gives effect to a 1-for-35 reverse stock split of shares of Aerovate common stock immediately prior to the Merger. The par value per share and the number of authorized shares were not adjusted as a result of the Exchange Ratio. The shares of Company common stock underlying outstanding stock options, restricted stock awards, and other equity instruments were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased in accordance with the terms of the agreements governing such securities. All references to common stock, options to purchase common stock, common stock share data, per share data, and related information contained in the condensed consolidated financial statements have been retrospectively adjusted to reflect the effect of the Exchange Ratio for all periods presented, unless otherwise specifically indicated or the context otherwise requires.

Immediately prior to the completion of the Merger, and in order to provide Jade with additional capital for its development programs, Pre-Merger Jade entered into a subscription agreement with certain investors (the “Subscription Agreement”), pursuant to which Pre-Merger Jade issued and sold, and certain new and existing investors purchased,43,947,116 shares of Pre-Merger Jade common stock and 12,305,898 pre-funded warrants, exercisable for 12,305,898 shares of pre-exchange Pre-Merger Jade common stock (before giving effect to the Exchange Ratio), at a purchase price of $5.9407 per share or $5.9406 per Pre-Merger Jade pre-funded warrant, for an aggregate amount of $334.2 million, which included $95.0 million of proceeds previously received from the issuance of Convertible Notes (as defined herein) and accrued interest of $8.3 million on such Convertible Notes and the related conversion of the Convertible Notes into shares of Pre-Merger Jade common stock and Pre-Merger Jade pre-funded warrants (the “Pre-Closing Financing”). At the Closing, based on the Exchange Ratio, the Pre-Merger Jade common stock and Pre-Merger Jade pre-funded warrants subscribed for were converted into the right to receive 27,734,940 shares of Aerovate common stock and 7,766,247 Aerovate pre-funded warrants.

The Merger was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Pre-Merger Jade was deemed to be the accounting acquirer for financial reporting purposes. This determination was primarily based on the fact that, immediately following the Merger: (i) Pre-Merger Jade stockholders owned a substantial majority of the voting rights in the combined company; (ii) Pre-Merger Jade’s largest stockholders retained the largest interest in the combined company; (iii) Pre-Merger Jade designated a majority of the initial members of the board of directors of the combined company; and (iv) Pre-Merger Jade’s executive management team became the management team of the combined company. Accordingly, for accounting purposes: (i) the Merger was treated as the equivalent of Pre-Merger Jade issuing stock to acquire the net assets of Aerovate, and (ii) the reported historical operating results of the combined company prior to the Merger are those of Pre-Merger Jade. Additional information regarding the Merger is included in Note 3.

Redomestication

On April 28, 2025, Jade changed its jurisdiction of incorporation from the State of Delaware to the State of Nevada (the “Redomestication”) pursuant to a plan of conversion. The Redomestication became effective on April 28, 2025.

The common stock of the Nevada corporation resulting from the conversion continues to be traded on The Nasdaq Capital Market (“Nasdaq”) under the symbol “JBIO.” The Redomestication did not cause any interruption in the trading of such common stock.

Liquidity and Going Concern

Since its inception, the Company has devoted substantially all of its resources to advancing the development of its portfolio of programs, organizing and staffing the Company, business planning, raising capital, and providing general and administrative support for these operations. Current and future programs will require significant research and development efforts, including preclinical and clinical trials, and, if the Company is successful in obtaining regulatory approval for one or more product candidates, significant commercialization efforts. Until such time as the Company can generate significant revenue from product sales, if ever, the Company expects to finance its operating activities principally through equity offerings.

The Company has not generated any revenue from product sales or other sources and has incurred significant operating losses and negative cash flows from operations since inception. The Company has incurred a net loss of$32.1 million and$70.3 million for the three and six months ended June 30, 2025, respectively. For the six months ended June 30, 2025, the Company used net cash of $38.9 million for its operating activities. As of June 30, 2025, the Company had cash and cash equivalents of$220.9 million.

The Company expects that its research and development and general and administrative costs will continue to increase significantly, including in connection with conducting future pre-clinical activities and clinical trials and manufacturing for its product candidates and providing general and administrative support for its operations, including the costs associated with operating as a public company. The Company expects that its existing cash and cash equivalents of $220.9 million as of June 30, 2025 will be sufficient to fund its forecasted operating expenses and capital expenditure requirements for at least 12 months from the date these unaudited condensed consolidated financial statements were issued.

2. Summary of Significant Accounting Policies

The Company’s significant accounting policies are disclosed in Note 2 to its audited financial statements as of December 31, 2024 and June 18, 2024 and for the period from June 18, 2024 (inception) to December 31, 2024 and the related notes thereto in Aerovate’s definitive proxy statement/prospectus filed on Form S-4 with the SEC, most recently amended on March 24, 2025 and declared effective on March 25, 2025, beginning on page F-22. Since the date of those financial statements, there have been no changes to the Company's significant accounting policies except as noted below.

Foreign Currency and Currency Translation

Assets and liabilities in foreign currency amounts are translated into United States dollars at the exchange rate in effect on the condensed consolidated balance sheet date. Income and expenses are translated at the average exchange rate in effect during the period. Unrealized translation gains and losses are recorded as a translation adjustment, which is included in the Company’s condensed consolidated statements of convertible preferred stock and stockholders’ equity (deficit) as a component of accumulated other comprehensive loss. Adjustments that arise from exchange rate changes on transactions denominated in a currency other than the functional currency are included in other expense, net in total expense, net in the Company’s condensed consolidated statements of operations and comprehensive loss.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation expense is recognized using the straight-line method over the estimated useful life of each asset as follows:

Leases

The Company evaluates arrangements entered into to determine whether or not it includes a lease. At the lease commencement date, when control of the underlying asset is transferred from the lessor to the Company, the Company classifies a lease as either an operating or finance lease and recognizes a right-of-use (“ROU”) asset and a current and non-current lease liability, as applicable, in the balance sheet if the lease has a term greater than one year. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise its option.

At the lease commencement date, operating lease liabilities and their corresponding ROU assets are recorded at the present value of future minimum lease payments over the expected remaining lease term. The Company determines the present value of lease payments using the implicit rate, if it is readily determinable, or the incremental borrowing rate for the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate to discount lease payments. The incremental borrowing rate represents an estimated rate of interest that the Company would have to pay to borrow equivalent funds on a collateralized basis at the lease commencement date. For operating leases, lease expense for lease payments is recognized on a straight-line basis over the lease term. For finance leases, lease expense includes amortization expense of the ROU asset recognized on a straight-line basis over the lease term and interest expense recognized on the finance lease liability. In addition, certain adjustments to the ROU asset may be required for items such as lease prepayments, incentives received or initial direct costs. As of June 30, 2025, the Company hasone operating lease andno finance leases.

The Company accounts for lease and non-lease components related to operating leases as a single lease component. The Company has elected that costs associated with leases having an initial term of 12 months or less are recognized in the condensed consolidated statement of operations and comprehensive loss on a straight-line basis over the lease term and are not recorded on its condensed consolidated balance sheets. Variable lease expense is recognized as incurred and consists primarily of real estate taxes, utilities, and other office space related expenses.

Classification of Convertible Preferred Stock

Prior to the reverse recapitalization, Pre-Merger Jade had classified the Pre-Merger Jade Series Seed Convertible Preferred Stock outside of stockholders’ equity (deficit) on the Company’s condensed consolidated balance sheet because the holders of such stock had certain liquidation rights in the event of a deemed liquidation event that, in certain situations, was not solely within the control of Pre-Merger Jade and would require the redemption of the then-outstanding convertible preferred stock.

Upon the closing of the Merger, the Company converted the Pre-Merger Jade Series Seed Convertible Preferred Stock to Series A Preferred Stock and has classified the Series A Preferred Stock within stockholders’ equity (deficit) on its condensed consolidated balance sheet because the Series A Preferred Stock is not redeemable or puttable to the Company by the holder under any circumstances.

Net Loss per Share Attributable to Common Stockholders

Basic and diluted net loss attributable to stockholders per share is presented in conformity with the two-class method required for participating securities (Pre-Merger Jade Series Seed Convertible Preferred Stock). Basic earnings per share is computed by dividing net income available to each class of shares by the weighted-average number of shares of common stock and participating securities outstanding during the period. Pre-funded warrants were included as the exercise price is negligible and these warrants are fully vested and exercisable. Series A Preferred Stock shares the same characteristics as common stock and has no substantive preference attributed to them and, accordingly, has been considered a class of common stock in the computation of net loss per share regardless of their legal form.

Net loss is allocated to common stock based on its proportional ownership on an as-converted basis. Net loss is not allocated to participating securities as they do not have an obligation to fund losses. The weighted-average number of shares outstanding of common stock reflects changes in ownership over the periods presented.

Diluted net loss per share is computed by dividing the net loss attributable to stockholders adjusted for income (expenses), net of tax, related to any diluted securities, by the weighted-average number of shares of common stock and potentially dilutive securities outstanding for the period. For purposes of this calculation, stock options to purchase common stock, and unvested shares of restricted stock awards (“RSAs”) are considered potentially dilutive securities.

The Company generated a net loss for the periods presented. Accordingly, basic and diluted net loss per share is the same because the inclusion of the potentially dilutive securities would be anti-dilutive.

Recently Issued Accounting Pronouncements Not Yet Adopted

In May 2025, the Financial Accounting Standards Board (“FASB”) issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity (“ASU 2025-03”), which revises current guidance for determining the accounting acquirer for a transaction effected primarily by exchanging equity interests in which the legal acquiree is a variable interest entity that meets the definition of a business. The amendments require that an entity consider the same factors that are currently required for determining which entity is the accounting acquirer in other acquisition transactions. ASU 2025-03 is effective for the Company’s annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, with early adoption permitted. ASU 2025-03 is required to be applied prospectively. As of the date of these unaudited condensed consolidated financial statements, the Company has not early adopted ASU 2025-03, therefore it did not apply the amendment to the Merger which closed on April 28, 2025.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU expands disclosures in an entity’s income tax rate reconciliation table and disclosures regarding taxes paid both in the U.S. and foreign jurisdictions. This update is effective beginning with the Company’s 2025 fiscal year annual reporting period. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures(Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”). The amendments in ASU 2024-03 require public entities to disclose specified information about certain costs and expenses. ASU 2024-03 is effective for the Company’s annual reporting period beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

3. Reverse Recapitalization and Pre-Closing Financing

Asdescribed within the Reverse Recapitalization and Pre-Closing Financing section in Note 1, on April 28, 2025, the reverse Merger between Pre-Merger Jade and Aerovate was consummated. The Merger was accounted for as a reverse recapitalization in accordance with U.S. GAAP. At the effective time of the Merger, substantially all of the assets of Aerovate consisted of cash and cash equivalents and other non-operating assets and liabilities. No goodwill or intangible assets were recognized as a result of the Merger.

As part of the recapitalization, the Company acquired the assets and assumed the liabilities listed below (in thousands):

4. Fair Value Measurements

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2025 and December 31, 2024 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine the fair value (in thousands):

Cash equivalents consist of money market funds, which were valued by the Company based on quoted market prices, which represent a Level 1 measurement within the fair value hierarchy. The Convertible Notes payable were revalued at each remeasurement-date, prior to the conversion of the Convertible Notes into Pre-Merger Jade common stock and Pre-Merger Jade pre-funded warrants upon the Closing, using inputs that are generally unobservable and reflect management’s estimates of assumptions that market participants would use in pricing the liability, which represent a Level 3 measurement within the fair value hierarchy. For the six months ended June 30, 2025 and the period from June 18, 2024 (inception) to December 31, 2024, there were no transfers between Level 1, Level 2 and Level 3 measurements within the fair value hierarchy.

The following table presents the changes in the fair value of the Level 3 Convertible Notes payable (in thousands):

The Convertible Notes payable in the table above consists of the fair value of an aggregate principal amount of $95.0 million, and a fair value adjustment of $34.2 million, which includes accrued interest of $8.3 million, in Convertible Notes which the Company issued and sold to certain investors. Each holder of Convertible Notes was expected to contribute the principal amount and all accrued interest under the applicable Convertible Note in exchange for the Company’s common stock or non-voting preferred stock in connection with a financing event under the Convertible Notes (see Note 6). As of December 31, 2024 the fair value of Convertible Notes was $107.6 million. The Company’s valuation of the Convertible Notes payable utilized a scenario-based valuation analysis, which incorporated assumptions and estimates to value the Convertible Notes and a probability assessment of the achievement of the Next Equity Financing (as defined in the Convertible Notes). The Company assessed these assumptions and estimates on a quarterly basis as additional information impacting the assumptions was obtained. Immediately prior to the effective time of the Merger, shares of Pre-Merger Jade Common Stock and pre-funded warrants were issued pursuant to the conversion of the Convertible Notes (including accrued interest), which automatically converted into 9,433,831 shares of Jade Common Stock and 4,289,744 Jade pre-funded warrants at the effective time of the Merger.

The Convertible Notes were issued on July 24, 2024 and September 30, 2024. The following table presents the significant assumptions related to the change in fair value for the period ending December 31, 2024:

5. Accrued Expenses and Other Current Liabilities

Accrued expenses and other current liabilities consisted of the following (in thousands):

6. Convertible Notes Payable

In July 2024, the Company entered into the Purchase Agreement with a series of investors, pursuant to which the Company issued the convertible notes (the “Convertible Notes”) with an initial principal amount of $80.0 million (of which $20.0 million is from Fairmount, a related party). In September 2024, the Company received an additional $15.0 million in gross proceeds from issuing additional Convertible Notes to additional investors. Under the terms of the Convertible Notes, the principal amount and all accrued interest of the Convertible Notes would automatically convert into the Company’s common stock, pre-funded warrants or preferred stock in connection with the closing of a Next Equity Financing or certain other events (e.g., a sale of substantially all Company assets, a merger, etc.). On April 28, 2025, this automatic conversion took place. The Convertible Notes accrued interest at a rate of 12.0% per annum, compounded annually. All unpaid interest and principal were scheduled to mature on December 31, 2026 (the “Maturity Date”). Prepayment was not permitted without prior written consent of the majority of the holders of the Convertible Notes. The principal payment along with the accrued interest on each Convertible Note was due in full on the Maturity Date.

In connection with the automatic conversion described above, the Convertible Notes were convertible into a number of shares of common stock equal to the quotient obtained by dividing the initial purchase price plus accrued and unpaid interest by the conversion price of the Convertible Notes, which is the product resulting from multiplying the price per share in the Next Equity Financing by 80% (“conversion price”).

There was less than $0.1 million of debt issuance cost incurred in connection with the Convertible Notes which was recognized in the financial statements for the period from June 18, 2024 (inception) to December 31, 2024. The Convertible Notes were recorded at the fair value of $95.0 million on the respective issuance dates and were remeasured to the fair value of $107.6 million as of December 31, 2024. The Convertible Notes were remeasured immediately prior to the Closing with a fair value of $129.2 million. For the three and six months ended June 30, 2025, the change in fair value of $6.2 million and $21.6 million, respectively, which includes accrued interest of $0.8 million and $3.6 million, respectively, was recorded within other expense, net in the Company's condensed consolidated statement of operations and comprehensive loss.

Immediately prior to the effective time of the Merger, the Convertible Notes converted into shares of Pre-Merger Jade Common Stock and Pre-Merger Jade pre-funded warrants based on the aggregate principal amount of $95.0 million plus unpaid accrued interest divided by the conversion price in connection with the Pre-Closing Financing. As of June 30, 2025, there wereno Convertible Notes outstanding. At the effective time of the Merger, the Pre-Merger Jade shares and warrants issued upon conversion of the Convertible Notes (including accrued interest) automatically converted into 9,433,831 shares of Pre-Merger Jade Common Stock and 4,289,744 Pre-Merger Jade pre-funded warrants.

7. Convertible Preferred Stock and Stockholders' Equity

Pre-Funded Warrants

In April 2025, pursuant to the Subscription Agreement and immediately prior to the Closing, certain new and current investors purchased Pre-Merger Jade pre-funded warrants, which, at the effective time of the Merger, were exercisable for 7,766,247 shares of Pre-Merger Jade Common Stock, at a price of $0.0001 per share. At the Closing, the Pre-Merger Jade common stock and Pre-Merger Jade pre-funded warrants were converted into shares of the Company common stock and Company pre-funded warrants, respectively.

The pre-funded warrants were recorded as a component of stockholders’ equity (deficit) within additional paid-in-capital and have no expiration date. As of June 30, 2025,390,853 of the pre-funded warrants have been exercised and 7,375,394 pre-funded warrants remain outstanding.

Convertible Preferred Stock

In June 2024, Pre-Merger Jade issued 20,000,000 shares of Series Seed Convertible Preferred Stock to a related party, Fairmount Healthcare Fund II L.P., an affiliate fund of Fairmount, at a purchase price of $0.0001 per share for gross proceeds of less than $0.1 million.

Upon the issuance of the Series Seed Convertible Preferred Stock, the Company assessed the embedded conversion and liquidation features of the securities as described below and determined that such features did not require the Company to separately account for these features as embedded derivatives.

In April 2025, upon the Closing, the Pre-Merger Jade Series Seed Convertible Preferred Stock was converted to 12,622 shares of Company Series A Preferred Stock.

As of June 30, 2025, Series A Preferred Stock consisted of the following (in thousands, except share amounts):

Pursuantto the Certificate of Designation of Preferences, Rights and Limitations of the Series A Preferred Stock (the “Series A Certificate of Designation”) filed in connection with the Redomestication, holders of Series A Preferred Stock are entitled to receive dividends on shares of Series A Preferred Stock equal to, on an as-if-converted-to-Company common stock basis, and in the same formas, dividends actually paid on shares of Company common stock. Except as provided in the Series A Certificate of Designation or as otherwise required by law, the Series A Preferred Stock does not have voting rights. The Series A Preferred Stock shall rank on parity with the Company common stock as to the distribution of assets upon any liquidation, dissolution, or winding-up of the Company. Each share of Series A Preferred Stock is convertible at the option of the holder, at any time, and without the payment of additional consideration by the holder. As of June 30, 2025, each outstanding share of Series A Preferred Stock was convertible into common stock at a ratio of approximately 1:1,000.

Common Stock

As of June 30, 2025, the Company has the auth ority to issue a total of 300,000,000 shares of common stock at a par value of $0.0001 per share. As of June 30, 2025,32,626,730 shares of common stock, including 495,739 RSAs were issued and outstanding. Each share of common stock entitles the holder to one vote, together with the holders of Series A Preferred Stock, on all matters submitted to the stockholders for a vote. The holders of common stock are entitled to receive dividends, if any, as declared by the Company’s board of directors (the “Board of Directors”), subject to the preferential dividend rights of the holders of Series A Preferred Stock.

As of June 30, 2025, there were 36,485,024 shares of common stock reserved for issuance for the potential conversion of shares of Series A Preferred Stock into common stock, shares issuable under the exercise of pre-funded warrants, shares reserved under the 2025 Equity Incentive Plan, shares reserved under the 2025 Employee Share Purchase Plan, and exercise of outstanding stock options for common stock under the 2024 Plan.

The Company’s RSAs have service-based vesting conditions only and vest over afour-year period or vest upon grant, during which time all unvested shares are subject to forfeiture by the Company in the event the holder’s service with the Company voluntarily or involuntarily terminates.

The following table summarizes the RSA activity for thesix months ended June 30, 2025:

Parade Warrant Obligation

In July 2024, the Company entered into the Paragon Option Agreement (as defined below) with Paragon and Parade Biosciences Holding, LLC (“Parade”). Under the terms of the Paragon Option Agreement, Parade will be entitled to grants of warrants to purchase a number of shares equal to 1.00%of the then outstanding shares of the Company’s stock, on a fully diluted basis, on December 31,

2025 and December 31, 2026, at the fair market value determined by the Board of Directors (the “Parade Warrant Obligation”). The grant dates for the issuance of warrants are expected to be December 31, 2025 and December 31, 2026, as all terms of the award, including number of shares and exercise price, will be known by all parties. Parade’s research and discovery related activities has a service inception period for the grant preceding the grant date, with the full award being vested as of the grant date with no post-grant date service requirement. As of June 30, 2025, the estimated fair value of warrants to be granted on December 31, 2025 was $5.5 million. For the three and six months ended June 30, 2025, the Company recognized $1.5 million and $2.4 million, respectively, as stock-based compensation expense related to the Parade Warrant Obligation. The warrants expected to be granted to Parade are liability-classified and after the initial recognition, the liability is adjusted to fair value at the end of each reporting period, with changes in fair value recorded in the condensed consolidated statements of operations and comprehensive loss within research and development.

The following table summarizes the assumptions used in calculating the fair value of the warrant obligation for thethree and six months ended June 30, 2025:

Stock-Based Compensation Expense

The following table summarizes the classification of the Company’s stock-based compensation expense in the condensed consolidated statement of operations and comprehensive loss (in thousands):

As of June 30, 2025, total unrecognized compensation cost related to the unvested stock options was $36.5 million, which is expected to be recognized over a weighted average period of approximately 3.5 years. As of June 30, 2025, total unrecognized compensation cost related to the unvested RSAs was less than less than $0.1 million, which is expected to be recognized over a weighted average period of 3.1 years. As of June 30, 2025, the unrecognized compensation cost related to the Parade Warrant Obligation was $1.9 million, which is expected to be recognized over a weighted average period of 0.5 years.

The following table summarizes the stock-based compensation based on type of award for thethree months ended June 30, 2025:

9. Income Taxes

The Company records a provision or benefit for income taxes on pre-tax income or loss based on its estimated effective tax rate for the year. Given the Company’s uncertainty regarding future taxable income, the Company maintains a full valuation allowance on its deferred tax assets. There wasno income tax expense recorded for thethree and six months ended June 30, 2025, or for the period from June 18, 2024 (inception) to June 30, 2024.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework, and the restoration of favorable tax treatment for certain business tax provisions. The Company is currently evaluating the potential impacts of the OBBBA on the Company’s financial statements.

10. Significant Agreements

Paragon Option Agreement

In July 2024, the Company entered into an Antibody Discovery and Option Agreement with Paragon and Parade (the “Paragon Option Agreement”) for the selected target, APRIL, for the Company’s initial research program, JADE-001. The Paragon Option Agreement, was amended in September 2024 to add two additional undisclosed targets for additional research programs named JADE-002 and JADE-003. Under the Paragon Option Agreement, Jade has the exclusive option (an “Option”), on a Research Program-by-Research Program (as defined below) basis, to enter into a separate agreement with Paragon consistent with a set of terms that are pre-negotiated and attached to the Paragon Option Agreement as an exhibit (a “License Agreement”). If the Company exercises its options and finalizes the related license agreement, it will be required to make non-refundable milestone payments to Paragon of up to $12.0 million under each respective agreement upon the achievement of certain clinical development milestones, up to $10.0 million under each respective agreement upon the achievement of certain regulatory milestones, as well as tiered royalty payments in the low-to-mid single-digits beginning on the first commercial sale of each developed product. From time to time, the Company can choose to add additional targets to the Paragon Option Agreement by mutual agreement with Paragon.

Under the terms of the Paragon Option Agreement, Paragon agreed to perform certain research activities to discover, generate, identify, and characterize one or more antibody candidates directed to certain mutually agreed therapeutic targets of interest to Jade (each, a “Research Program”). The Option with respect to each Research Program is exercisable at Jade’s sole discretion at any time during the period beginning on the initiation of activities under the associated Research Program and ending a specified number of days following the delivery of the data package from Paragon related to the results of the Research Program (an “Option Period”). The Paragon Option Agreement requires Jade, Paragon, and Parade to develop a research plan for each target that includes design, modeling, synthesis, evaluation, and other mutually agreed activities (each, a “Research Plan”), which activities may include performing preclinical studies. Paragon will perform the activities set forth in each Research Plan on the timelines set forth in such Research Plan and in compliance with a mutually agreed budget. Each Research Program will be overseen and coordinated by a joint development committee consisting oftwo employees from Jade andtwo employees from Paragon, with Jade and Paragon each havingone vote with respect to decisions of the committee. When Paragon and Parade have produced an antibody against a selected target, and upon the completion of each Research Program, Paragon and Parade will deliver to Jade a data package that includes sequence information for all then-existing antibodies and information directed to such target. Jade, Paragon and Parade have developed a Research Plan for JADE-001, JADE-002, and JADE-003 consistent with the foregoing, and Paragon and Parade have delivered the respective antibodies in accordance with the Research Plans.

Any License Agreement entered into with respect to a given Research Program is expected to be consistent with pre-negotiated terms attached to the Paragon Option Agreement and shall contain the same milestone payment obligations as the Paragon Option Agreement, provided that any milestone set in the Paragon Option Agreement that has not yet been achieved and is duplicated in such License Agreement shall no longer be achievable and payable under the terms of the Paragon Option Agreement and shall only be achievable under the terms of the License Agreement. For the avoidance of doubt, if a milestone is achieved and paid by Jade pursuant to the Paragon Option Agreement for a certain Research Program, then there shall be no milestone payment due for the achievement of such milestone under a subsequently executed License Agreement for such Research Program. Further, under a License Agreement, Jade would also be required to make royalty payments to Paragon in the low single-digit percentage range based on net sales of products, subject to certain reductions. The royalty term will terminate on a product-by-product and country-by-country basis upon the later of the expiration of the last-to-expire valid claim within the relevant patent rights or the twelfth anniversary of the first commercial sale of such product in such country.

Unless terminated earlier, the Paragon Option Agreement shall continue in force on a Research Program-by-Research Program basis until the later of: (i) the end of the Option Period for such Research Program, as applicable, if such Option is not exercised by the Company; (ii) if the Company exercises its Option with respect to a Research Program, but the parties are unable to finalize and execute a License Agreement within 30 days, the expiration of such 30-day period (subject to any mutually agreed extension of such period); and (iii) the expiration of the applicable Research Term (as defined under the Paragon Option Agreement). The Company may terminate the Paragon Option Agreement or any Research Program at any time for any or no reason upon 30 days’prior written notice to Paragon, provided that the Company must pay certain unpaid fees due to Paragon upon such termination, as well as any non-cancellable obligations reasonably incurred by Paragon in connection with its activities under any terminated Research Program. Paragon may terminate the Paragon Option Agreement or a Research Program immediately upon written notice to the Company if, as aresult of any action or failure to act by the Company or its affiliates, such Research Program or all material activities under the applicable Research Plan are suspended, discontinued or otherwise delayed for a certain consecutive number of months. Each party has the right to terminate the Paragon Option Agreement or any Research Program upon (i)30 days’ prior written notice of the other party’s material breach that remains uncured for the 30-day period and (ii) the other party’s bankruptcy.

Under the Paragon Option Agreement, the Company is responsible for any additional development costs incurred by Paragon, which from January 1, 2025 to June 30, 2025 totaled $2.0 million relating to APRIL, of which $1.9 million was recognized as research and development expense in the Company’s condensed consolidated statement of operations and comprehensive loss during thesix months ended June 30, 2025 and the remaining $0.1 million was recognized in general and administrative expenses. For the three months ended June 30, 2025 the Company incurred a total of $0.6 million which was recognized as research and development expense in the Company's condensed consolidated statement of operations and comprehensive loss. As of June 30, 2025, a total of $0.6 million related to APRIL remains in related party accrued expenses and other current liabilities in the Company’s condensed balance sheet.

Additionally, the Company is responsible to reimburse Paragon for development costs related to JADE-002, which from January 1, 2025 to June 30, 2025 totaled $4.1 million and was recognized as research and development expense in the Company’s condensed consolidated statement of operations and comprehensive loss during thesix months ended June 30, 2025. The Company is also obligated to pay Paragon $1.5 million following the nomination of a development candidate for JADE-002 which occurred in March 2025 and was subsequently paid in April 2025. For the three months ended June 30, 2025 the Company incurred a total of $0.8 million for JADE-002 under the Paragon Option Agreement, which was recognized as research and development expense in the Company's condensed consolidated statement of operations and comprehensive loss. As of June 30, 2025, a total of $0.8 million related to JADE-002 remains in related party accrued expenses and other current liabilities in the Company's condensed balance sheet.

The Company was also obligated to reimburse Paragon for development costs related to JADE-003 for the period of January 1, 2025 to June 30, 2025 totaling $1.7 million relating to research and development costs, as well as for subsequent development costs related to JADE-003. These amounts were recognized as research and development expense in the Company’s condensed consolidated statement of operations and comprehensive loss during the six months ended June 30, 2025. For the three months ended June 30, 2025 the Company incurred a total of $0.9 million which was recognized as research and development expense in the Company's condensed consolidated statement of operations and comprehensive loss. As of June 30, 2025, a total of $0.9 million remains in the Company's condensed balance sheet in related party accrued expenses and other current liabilities.

Additionally, as part of the Paragon Option Agreement, on each of December 31, 2025 and December 31, 2026, Jade will grant Parade warrants to purchase a number of shares equal to 1.00% of Jade’s outstanding capital stock as of the date of the grant on a fully-diluted basis, with an exercise price equal to the fair market value of the underlying shares of Jade common stock on each respective grant date. Parade is an entity formed by Paragon as a vehicle to hold equity in Jade in order to share profits with certain employees of Paragon and will not perform any substantive role under the Paragon Option Agreement other than to receive such warrants. The warrants are liability-classified and after the initial recognition, the liability is adjusted to fair value at the end of each reporting period, with changes in fair value recorded in the condensed consolidated statement of operations and comprehensive loss (see Note 8).

The Company expenses the fees incurred under the Paragon Option Agreement as the associated costs are incurred when the underlying services are rendered. Such amounts are classified within research and development expenses in the accompanying condensed consolidated statement of operations and comprehensive loss.

The Company concluded that the rights obtained under the Paragon Option Agreement represent an asset acquisition whereby the underlying assets comprise in-process research and development assets with no alternative future use. The Paragon Option Agreement did not qualify as a business combination because substantially all of the fair value of the assets acquired was concentrated in the exclusive license options, which represent a group of similar identifiable assets. The research initiation fees represent a one-time cost on a research program-by research program basis for accessing research services or resources with benefits that are expected to be consumed in the near term, therefore the amounts paid are expensed as part of research and development costs immediately. Amounts paid as reimbursements of on-going development cost, monthly development cost fee and additional development expenses incurred by Paragon due to work completed for selected targets prior to the effective date of the Paragon Option Agreement and Amendment to the Paragon Option Agreement that associated with services being rendered under the related Research Programs is recognized as research and development expense when incurred.

JADE-001 License Agreement

On October 30, 2024, Jade entered into a License Agreement with Paragon for all antibodies discovered, generated, identified or characterized by Paragon in the course of performing the JADE-001 research program directed to APRIL, antibodies created by Jade derived from the licensed antibodies and directed to APRIL, and products that comprise the foregoing (the “JADE-001 License

Agreement”)consistent with the pre-negotiated terms agreed to upon execution of the Paragon Option Agreement, pursuant to which Paragon granted Jade a royalty-bearing, worldwide, exclusive and sublicensable license with respect to certain inventions, patent rights, sequence information and other intellectual property rights related to monospecific antibodies directed at the APRIL target (the “Licensed Antibody Technology”) to use, make, sell, import, export and otherwise exploit certain monospecific antibodies and products targeting APRIL in the field of prophylaxis, palliation, treatment and diagnosis of human disease and disorders in all therapeutic areas (the “field”) and worldwide (the “territory”). Under the terms of the JADE-001 License Agreement, Jade is obligated to pay Paragon up to $22.0 million based on specific development and regulatory milestones, including a $1.5 million fee for nomination of a development candidate, which was paid in December 2024, and a further milestone payment of $2.5 million upon the first dosing of a human patient in a Phase 1 trial. Following the execution of the JADE-001 License Agreement, Jade is solely responsible for, and has sole authority and control over, all aspects of the development, manufacturing and commercialization of product candidates under the JADE-001 program, including regulatory strategy, communications, filings and activities (including clinical trials). Paragon also granted Jade a royalty-bearing, worldwide, non-exclusive, sublicensable right and license under the Licensed Antibody Technology to use, make, sell, import, export, or otherwise exploit certain multispecific antibodies and products targeting APRIL. In addition, the following summarizes other key terms of the JADE-001 License Agreement:

•

Paragon will not conduct any new campaigns that generate APRIL monospecific antibodies in the field for at least five years.

•

Paragon may pursue the development and commercialization of multispecific antibodies and products directed at the APRIL target in the field and in the territory, and Jade has a right of first negotiation for any such multispecific antibodies and products proposed by Paragon for a period of five years from the execution of the JADE-001 License Agreement. If Jade does not exercise its right of first negotiation, or if the parties are unable to agree on a definitive agreement, Paragon may proceed without any obligations to Jade with respect to the right of first negotiation, and Jade’s non-exclusive license will exclude any multispecific antibodies and products that were the subject of the right of first negotiation.

•

Jade will pay Paragon a low-to-mid single-digit percentage royalty based on annual net sales of the products in the field and in the territory, and a mid single-digit percentage royalty based on annual net sales of the multispecific products in the field and in the territory, subject to a 30% reduction if there is no valid patent covering the product in the country.

•

The royalty term ends on the later of (i) the twelfth anniversary of such date or (ii) the expiration of the last-to- expire valid patent covering the product or the multispecific product in the country at issue.

•

The JADE-001 License Agreement may be terminated on 60 days’ notice by Jade, upon material breach without cure; and to the extent permitted by law, upon a party’s insolvency or bankruptcy.

•

With respect to patents licensed to Jade under the JADE-001 License Agreement that have been filed as of the effective date of the JADE-001 License Agreement, Jade will control the preparing, filing, prosecuting and maintenance of such patents. With respect to patents filed after the effective date of the JADE-001 License Agreement, Paragon will control the preparing, filing, prosecuting and maintaining of such patents until the final deliverable for the relevant research program is delivered to Jade, after which Jade will control the preparing, filing, prosecuting and maintain of such patents.

•

Jade shall have the right to grant sublicenses under the JADE-001 License Agreement, provided that (i) any sublicense agreement is consistent with all relevant terms, conditions and restrictions of the JADE-001 License Agreement, (ii) Jade provides Paragon with a copy of each sublicense agreement and any amendments thereto within 30 days following execution thereof and (iii) Jade remains responsible for all payments and obligations due under the JADE-001 License Agreement.

•

On a product-by-product basis, Jade is obligated to pay sublicensing fees of up to approximately $20.1 million, mainly upon the achievement of commercial milestones. Jade has the option, during specified periods, to pay a non-refundable lump-sum buyout payment on a product-by-product basis to extinguish future milestone payment obligations with respect to such product.

In December 2024, Jade completed its selection of its development candidate for the JADE-001 program, which is called JADE101, and Jade paid Paragon the related $1.5 million milestone payment and recorded the payment as research and development expense. In December 2024, Jade recorded a $0.1 million nonrefundable sublicensee fee under the JADE-001 License Agreement as research and development expense.

Cell Line License Agreement

On February 3, 2025, the Company entered into an amended and restated cell line license agreement (the “Cell Line License Agreement”) with WuXi Biologics Ireland Limited (“WuXi Biologics Ireland”). Under the Cell Line License Agreement, the Company received a non-exclusive, worldwide, sublicensable license to certain of WuXi Biologics Ireland’s patent rights, know-how, cell line, biological materials and media and feeds to develop, manufacture, have manufactured, make, have made, import, sell, keep, commercialize and otherwise deal in, use and exploit certain therapeutic products produced through the use of the cell lines licensed by WuXi Biologics Ireland under the Cell Line License Agreement (the “WuXi Biologics Ireland Licensed Products”). JADE-001 is, and Jade anticipates that any future product candidates under the JADE-001 and JADE-002 programs will be, manufactured using a cell line licensed under the Cell Line License Agreement. A cell line has not yet been selected for the JADE-003 program.

In consideration for the license, the Company incurred a non-refundable license fee of $0.2 million in November 2024, which was recorded as research and development expense. Additionally, in June 2025 the Company incurred a non-refundable license fee of $0.1 million, which was recorded as research and development expense. Additionally, if the Company manufactures all of its commercial supplies of bulk drug product for a particular product with a manufacturer other than WuXi Biologics Ireland or its affiliates, it is required to make royalty payments to WuXi Biologics Ireland in an amount equal to a fraction of a single digit percentage of global net sales of the WuXi Biologics Ireland Licensed Products manufactured by a third-party manufacturer (the “Royalty”). If the Company manufactures part of its commercial supplies of the WuXi Biologics Ireland Licensed Products with WuXi Biologics Ireland or its affiliates, then the Royalty will be reduced accordingly on a pro rata basis. The Company has the option, at any time, to pay WuXi Biologics Ireland a non-refundable lump-sum royalty buyout payment on a drug product-by-drug product basis to extinguish future Royalty obligations with respect to such drug product.

The Cell Line License Agreement will continue indefinitely unless terminated (i) by the Company upon six months’ prior written notice and its payment of all undisputed amounts due to WuXi Biologics Ireland through the effective date of termination, (ii) by either party for a material breach by the other party that remains uncured for 60 days after written notice, (iii) by WuXi Biologics Ireland if the Company fails to make a payment and such failure continues for 30 days after receiving notice of such failure, or (iv) by either party upon the other party’s bankruptcy.

11. Leases

In February 2025, the Company entered into a nonc ancelable operating lease agreement for office space located in Vancouver, Canada. The lease commencement date is March 1, 2025, with an initial term of 67 months. The rent commencement date is October 1, 2025. The total lease payment is expected to be approximately $1.2 million of principal payments plus $0.4 million of interest payments over the initial lease term. Payments for rent are made in Canadian dollars and therefore subject to foreign exchange impact. Lease liabilities are based on the net present value of the remaining lease payments over the remaining lease term. In determining the present value of lease payments, the Company used its incremental borrowing rate when measuring operating lease liabilities as discount rates were not implicit or readily determinable.

As of June 30, 2025, the Company had $0.8 million of operating lease ROU asset and long term lease liability of $0.8 million on its condensed consolidated balance sheets. As of June 30, 2025, the operating lease arrangement had a remaining lease term of 5.3 years and an internal borrowing rate of return of 14.24%. For thethree and six months ended June 30, 2025, the Company recorded operating lease expense of less than $0.1 million and $0.1 million, respectively, in general and administrative expenses in its condensed consolidated statements of operations and comprehensive loss. No lease payments were made during the three and six months ended June 30, 2025 related to the Company's Vancouver office space.

As of June 30, 2025, the total remaining operating lease payments included in the measurement of lease liabilities was as follows (in thousands):

12. Commitments and Contingencies

401(k) Plan

The Company maintains a defined-contribution plan under Section 401(k) of the Internal Revenue Code of 1986 (the “401(k) Plan”). The 401(k) Plan covers all employees who meet defined minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. Matching contributions to the 401(k) Plan may be made at the discretion of management. For the three and six months ended June 30, 2025 and the period from June 18, 2024 (Inception) through June 30, 2024, the Company hasnot recorded any expense related to 401(k) Plan match contributions.

Indemnification Agreements

In the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with each of its directors and executive officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or executive officers. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many cases, unlimited. To date, the Company hasnot incurred any material costs as a result of such indemnifications. The Company is not aware of any indemnification arrangements that could have a material effect on its financial position, results of operations or cash flows, and it hasnot accrued any liabilities related to such obligations in its condensed consolidated financial statements as of June 30, 2025.

Legal Proceedings

From time to time, the Company may become involved in legal proceedings or other litigation relating to claims arising in the ordinary course of business. The Company accrues a liability for such matters when it is probable that future expenditures will be made and that such expenditures can be reasonably estimated. Significant judgment is required to determine both probability and estimated exposure amount. Legal fees and other costs associated with such proceedings are expensed as incurred. As of June 30, 2025, the Company was not a party to any material legal proceedings or claims.

13. Net Loss per Share

Basic and diluted net loss per share attributable to common stockholders and Series A Preferred stockholders was calculated as follows (in thousands, except share and per share amounts):

(1) The weighted average number of shares of as-converted Series A Preferred Stock used in the loss allocation was 8,780,522 and 4,438,505 for the three and six months ended June 30, 2025, respectively.

For the computation of basic net loss per share attributable to common stockholders, the amount of weighted-average common shares outstanding excludes all shares of unvested restricted common stock as such shares are not considered outstanding for accounting purposes until vested. The amount of weighted-average shares outstanding includes the pre-funded warrants as the exercise price is negligible and these warrants are fully vested and exercisable.

The potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have had an anti-dilutive effect were as follows:

14. Related Party Transactions

Paragon and Parade each beneficially own less than 5% of the Company’s share capital through their respective holdings of Company’s common stock.

Fairmount beneficially owns more than 5% of the Company’s capital, currently has two representatives appointed to the board of directors and beneficially owns more than 5% of Paragon.

The following is a summary of related party accounts payable and other current liabilities (in thousands):

15. Segment Reporting

The Company hasone reportable segment relating to the research and development of its programs, JADE-001, JADE-002, and JADE-003. The Company’s chief operating decision maker (“CODM”), its Chief Executive Officer, manages the Company’s operations on a consolidated basis and uses consolidated net loss for the allocation of resources and the assessment of performance. Although the Company’s financial reporting package that is reviewed and approved by the CODM disaggregates significant expenses such as program-level external research and development costs, personnel costs, including stock-based compensation expense, and professional and consulting fees, all decisions made by the CODM are based upon reviewing operating metrics and performance indicators at the Company-wide consolidated level and consolidated net loss. The CODM uses consolidated net loss to evaluate loss generated from the Company’s business activities in deciding how to allocate company resources and in monitoring budget versus actual results. Assets are also managed on a Company-wide consolidated basis.

The table below is a summary of the significant expenses categories regularly provided to the CODM (in thousands):
