Skye Bioscience, Inc.

1. Nature of Operations and Business Activities

Nature of Operations

Skye Bioscience, Inc. (the “Company” or “Skye”) was incorporated in Nevada on March 16, 2011. The Company is a clinical stage biotechnology company developing next-generation molecules that modulate G-protein-coupled receptors ("GPCRs") to treat obesity, overweight, and related conditions.

As of December 31, 2025, the Company has devoted substantially all its efforts to securing its product pipeline, carrying out its own research and development, preparing for and conducting clinical trials, building infrastructure and raising capital. The Company has not yet realized revenue from its planned principal operations and is a number of years away from potentially being able to do so.

Liquidity and Going Concern

The Company has incurred operating losses and negative cash flows from operations since inception and as of December 31, 2025, had a working capital of $18,888,688 and an accumulated deficit of 186,874,486. As of December 31, 2025, the Company had unrestricted cash, cash equivalents and short-term investments in the amount of $25,737,221. For the years ended December 31, 2025 and 2024, the Company incurred losses from operations of $58,163,565 and $30,192,718, respectively. For the years ended December 31, 2025 and 2024, the Company incurred net losses of $55,924,814 and $26,567,123, respectively. The Company expects to continue to incur significant losses and negative cash flows from operations through 2026 and expects to incur significant losses and negative cash flows from operations in the future.

The Company’s continued existence is dependent on its ability to raise sufficient additional funding to cover operating expenses and to carry out its research and development activities. As the Company is continuing its clinical trials, it has increased research and development spending and increased cash used in operating activities. This factor, among others, has resulted in an overall increase in cash used in operating activities for the year ended December 31, 2025. As of the date that these financials are filed, management estimates that the Company has sufficient capital to continue its operations through the fourth quarter of 2026, excluding the anticipated clinical cost of a proposed Phase 2b study and additional anticipated drug manufacturing costs to supply any such Phase 2b study. However, the Company's continued operations beyond the fourth quarter of 2026 will depend on its ability to successfully raise additional capital through various potential sources, such as equity and/or debt financings, or strategic relationships. If adequate funds are not available to the Company when needed it will be required to curtail or perhaps cease operations which would, in turn, further raise substantial doubt about its ability to continue as a going concern. These conditions give rise to substantial doubt as to the Company’s ability to continue as a going concern within one year after the date that these financial statements are issued.

It is possible that the Company may encounter issues relating to supply chain issues, a lack of production or laboratory resources, global economic and political conditions, pandemics or cyberattacks that could cause business disruptions and clinical trial delays which will need to be managed in the future. The factors to take into account in going concern judgments and financial projections include travel bans, restrictions, government assistance and potential sources of replacement financing, financial health of service providers and the general economy. In addition, increased inflation has had, and may continue to have, an effect on interest rates. Increased interest rates may adversely affect the terms under which the Company can obtain, any potential additional funding.

After considering the plans to alleviate substantial doubt, management has concluded that there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that these financial statements are issued. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

2. Summary of Significant Accounting Policies

Basis of Presentation

The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from those estimates.

Certain reclassifications have been made to the amounts in prior periods to conform to the current period’s presentation, including reclassifying discovery research and development expense amounts from external clinical development expenses into other research and development expenses, as described in Note 13, Segment Reporting. Such reclassifications did not have a material impact on the accompanying unaudited condensed consolidated financial statements.

Principles of Consolidation

The accompanying consolidated financial statements as of December 31, 2025, include the accounts of the Company and its wholly owned subsidiaries SKYE Bioscience Australia, EHT, BRB and Nemus Sub. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the consolidated financial statements in conformity with 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 the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates. The most significant accounting estimates inherent in the preparation of the Company’s financial statements include estimates and judgements used in determining stock based compensation expense, estimated legal contingencies and estimates related to the vendors' percentage of completion under its research and development contracts, which are not readily apparent from other sources.

Risks and Uncertainties

The Company’s operations are subject to a number of risks and uncertainties, including but not limited to, changes in the general economy, the size and growth of the potential market for the Company’s product candidates, uncertainties related to the current global environment, including economic factors such as inflation, and risks related to the global supply chain disruptions (Note 1), risks related to operating in a virtual environment, results of research and development activities, uncertainties surrounding regulatory developments in the United States, Canada, the European Union, and Australia and the Company’s ability to attract new funding.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. The carrying values of those investments approximate their fair value due to their short maturity and liquidity. Cash and cash equivalents includes cash on hand and amounts on deposit with financial institutions, which amounts may at times exceed federally insured limits. The Company has not experienced any losses on such accounts and does not believe it is exposed to any significant credit risk.

Property and Equipment, net

Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, generally three tofive years. Leasehold improvements are amortized over the shorter of the estimated useful life of the improvements or the remaining lease term. Expenditures for repairs and maintenance, which do not extend the useful life of the property and equipment, are expensed as incurred. Upon retirement, the asset cost and related accumulated depreciation are relieved from the accompanying Consolidated Balance Sheets.

Fair Value Measurements

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (the “exit price”) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. A fair value hierarchy based on three levels of inputs, of which the first two are considered observable, and the last is considered unobservable, is used to measure fair value:

Level 1: Valuations for assets and liabilities traded in active markets from readily available pricing sources such as quoted prices in active markets for identical assets or liabilities.

Level 2: Observable inputs (other than Level 1 quoted prices) such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.

Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

The carrying values of the Company’s financial instruments approximate their fair value due to their short maturities.

Income Taxes

The Company accounts for deferred income tax assets and liabilities based on differences between the financial reporting and tax bases of assets and liabilities, net operating loss carryforwards (the “NOLs”) and other tax credit carryforwards. These items are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period that includes the enactment date. Any interest or penalties would be recorded in the Company’s Consolidated Statements of Operations in the period incurred. When necessary, the Company recognizes interest and penalties related to income tax matters in income tax expense.

The Company records a valuation allowance against deferred tax assets to the extent that it is more likely than not that some portion or all of the deferred tax assets will not be realized. In making such determinations, management considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. Due to the substantial doubt related to the Company’s ability to utilize its deferred tax assets, a valuation allowance for the full amount of the deferred tax assets has been established at December 31, 2025 and 2024. As a result of this valuation allowance, there are no income tax benefits reflected in the accompanying Consolidated Statements of Operations to offset pre-tax losses.

The Company recognizes a tax benefit from uncertain tax positions when it is more likely than not (50%) that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position.

Warrants Issued in Connection with Financings

The Company generally accounts for warrants issued in connection with debt and equity financings as a component of equity, unless the warrants include a conditional obligation to issue a variable number of shares or there is a deemed possibility that the Company may need to settle the warrants in cash. For warrants issued with a conditional obligation to issue a variable number of shares or the deemed possibility of a cash settlement, the Company records the fair value of the warrants as a liability at each balance sheet date and records changes in fair value in other expense, net in the Consolidated Statements of Operations.

Research and Development Expenses and Licensed Technology

Research and development costs are expensed when incurred. These costs may consist of external research and development expenses incurred under agreements with third party contract research organizations and investigative sites; third party manufacturing organizations and consultants; license fees; employee-related expenses, which include salaries and benefits for the personnel involved in the Company’s preclinical; and clinical drug development activities, other expenses and equipment and laboratory supplies.

Costs incurred for the rights to use licensed technologies in the research and development process, including licensing fees and milestone payments, are charged to research and development expense as incurred in situations where the Company has not identified an alternative future use for the acquired rights, and are capitalized in situations where there is an identified alternative future use. None of the costs associated with the use of licensed technologies has been capitalized to date.

Stock-based compensation expense is estimated at the grant date based on the fair value of the award, and the fair value is recognized as expense ratably over the vesting period with forfeitures accounted for as they occur.

Upon the exercise of stock option awards, the Company's policy is to issue new shares of its common stock. The Company uses the Black-Scholes valuation method for estimating the grant date fair value of stock options using the following assumptions:

•Volatility - Stock price volatility is estimated over the expected term based on a blended daily rate of industry peers stock volatility.

•Expected term - The expected term is based on a simplified method which defines the life as the weighted average of the contractual term of the options and the vesting period for each award.

•Risk-free rate - The risk-free interest rate for the expected term of the option is based on the average market rate on U.S. Treasury securities in effect during the period in which the awards were granted.

•Dividends - The dividend yield assumption is based on the Company’s history and expectation of paying no dividends in the foreseeable future.

Additionally, the Company uses the Monte Carlo Simulation model to evaluate the derived service period and fair value of awards with market conditions, including assumptions of historical volatility and risk-free interest rate commensurate with the vesting term.

Loss Per Common Share

The Company applies ASC No. 260, Earnings per Share in calculating its basic and diluted loss per common share. Basic loss per common share is computed by dividing net loss available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Diluted loss per share of common stock is computed by giving effect to all potential common stock equivalents outstanding for the period determined using the treasury stock method. For purposes of this calculation, options to purchase common stock, restricted stock units and warrants to purchase common stock are considered to be common stock equivalents. In periods with a reported net loss, such common stock equivalents are excluded from the calculation of diluted net loss per share of common stock if their effect is anti-dilutive. For additional information regarding the loss per share (see Note 10).

Leases

The Company applies ASU, No. 2016-02, Leases (Topic 842), in accounting for operating lease arrangements.

At the inception of an arrangement, the Company determines whether the arrangement is, or contains, a lease based on the unique facts and circumstances present. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in the lease contract is typically not readily determinable. As such, the Company utilizes its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received.

Lease expense is recognized over the expected term on a straight-line basis. Operating leases are recognized on the Consolidated Balance Sheets as operating lease right-of-use assets, operating lease liability, current portion and operating lease liability, net of current portion.

Government Assistance

The Company adopted ASU 2021-10 Government Assistance on January 1, 2022. The Company accounts for the tax rebates received from the Australian Taxation Office ("ATO") under such guidance. The Company accounts for the rebates that it receives under the AusIndustry research and development tax incentive program under the income recognition model of IAS 20. Under this model, when there is reasonable assurance that the rebate will be received, the Company recognizes the income from the tax rebate as an offset to research and development expense during the period which the benefit applies to the research and development costs incurred. The total tax rebates received under the AusIndustry incentive program were $0 for the year ended December 31, 2025 related to incentives earned in the prior year and $493,362 for the year ended December 31, 2024.

Foreign Currency Translation

The Company’s reporting currency and the functional currency of its foreign subsidiaries is the United States dollar. The local currencies of its foreign subsidiaries are the Canadian Dollar (“CAD”) and Australian dollar (“AUD”). Assets and liabilities are remeasured based on the exchange rates at the balance sheet date 0.7305 for the CAD,0.6703 for the AUD as of December 31, 2025 and 0.6952 for the CAD and 0.623 for the AUD as of December 31, 2024, while expense accounts are remeasured at the weighted average exchange rate for the period 0.7249 for the CAD and 0.6645 for the AUD for the year ended December 31, 2025 and 0.7023 for the CAD and 0.6342 for the AUD as of December 31, 2024. Equity accounts are remeasured at historical exchange rates. The resulting remeasurement adjustments are recognized in general and administrative expenses in the consolidated financial statements.

During the years ended December 31, 2025 and 2024, the Company recorded foreign currency remeasurement gain of $96,190 and a loss of $148,023, respectively, which are reflected in general and administrative expenses in the accompanying Consolidated Statements of Operations.

Foreign currency gains and losses resulting from transactions denominated in foreign currencies are recorded in the Consolidated Statements of Operations. During the years ended December 31, 2025 and 2024, the Company recorded foreign currency transaction loss of $1,085,098 and gain of $49,984, respectively, which is reflected in the loss from operations in the accompanying consolidated statement of operations.

Commitments and Contingencies

The Company follows ASC 440, Commitments and ASC 450, Contingencies, subtopic 450-20 to report accounting for contingencies and commitments respectively. Certain conditions may exist as of the date the financial statements are issued, which may result in a loss to the Company, but which will only be resolved when one or more future events occur or fail to occur.

The Company assesses such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Company or un-asserted claims that may result in such proceedings, the Company evaluates the perceived merits of any legal proceedings or un-asserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein.

If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability would be accrued in the Company’s financial statements. If the assessment indicates that a potentially material loss contingency is not probable but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, and an estimate of the range of possible losses, if determinable and material, would be disclosed. Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the guarantees would be disclosed. Refer to Note 12 for additional information.

In accordance with ASC 450, Contingencies, subtopic 450-20, the Company does not reflect a contingency that may result in a gain until it is realized.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this ASU require disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), as well as the aggregate amount of other segment items included in the reported measure of segment profit or loss. This ASU requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. This ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. The amendments in this ASU should be applied retrospectively to all prior periods presented in the financial statements. The Company adopted the ASU and determined that its adoption did not have a material impact on the Company’s consolidated financial statements and related disclosures. As defined in the ASU, operating segments are components of an enterprise about which discrete financial information is regularly provided to the CODM in making decisions on how to allocate resources and assess performance for the organization. The Company operates and manages its business as one reportable and operating segment — pharmaceutical development. The Company’s CODM is the Chief Executive Officer. The Company’s CODM reviews consolidated operating results to make decisions about allocating resources and assessing performance for the entire Company. See Segment Note 13.

In December 2023, the FASB issued Accounting Standards Update ("ASU") 2023-09, Improvements to Income Tax Disclosures. This ASU requires greater disaggregation of information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. This ASU applies to all entities subject to income taxes and is intended to help investors better understand an entity’s exposure to potential changes in jurisdictional tax legislation and assess income tax information that affects cash flow forecasts and capital allocation decisions. This ASU is effective for annual periods beginning after December 15, 2024, with early adoption permitted. This ASU should be applied on a prospective basis although retrospective application is permitted. The Company adopted this ASU as of January 1, 2025, and the related disclosure, a tabular reconciliation of the provision for income taxes to the amount computed, is described in Note 11.

Recent Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued Accounting Standards Update ("ASU") 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional disclosure of the nature of expenses included in the income statement. The standard requires disclosures about specific types of expenses included in the expense captions presented in the income statement as well as disclosures about selling expenses. This ASU is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The requirements should be applied on a prospective basis while retrospective application is permitted. The Company is currently evaluating the impact the adoption of this ASU will have on its consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-11 – Interim Reporting (“ASU 2025-11”) which is intended to improve the navigability of the guidance in ASC 270, Interim Reporting, and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, and early adoption is permitted. The Company is currently evaluating the impact the adoption of ASU 2025-11 may have on the Company’s consolidated financial statements and disclosures.

In December 2025, the FASB issued its final Accounting Standard Update ("ASU") which makes improvements to the Accounting Standards Codification ("ASC") in response to feedback from stakeholders. This standard, issued as ASU 2025-12, specifically updates the ASC for a broad range of topics arising from technical corrections, unintended application of the ASC, clarifications, and other minor improvements. This update is effective for annual reporting periods beginning after December 15, 2026, including interim reporting periods within those annual reporting periods. The Company is currently evaluating the effect of this guidance on its financial statements and related disclosures.

3. Fair Value Measurement

The following table sets forth the Company’s financial instruments that were measured at fair value on a recurring basis by level within the fair value hierarchy:

4. Assets Acquisitions and Dispositions

Acquisition of Emerald Health Therapeutics, Inc.

On May 11, 2022, the Company entered into an Arrangement Agreement, as amended on June 14, 2022, July 15, 2022 and October 14, 2022 (the “Arrangement Agreement”) with Emerald Health Therapeutics, Inc., a corporation existing under the laws of the Province of British Columbia, Canada (“EHT”), pursuant to a plan of arrangement under the Business Corporations Act (British Columbia) (the “EHT Acquisition”).

At the time of the EHT Acquisition there were arrangements in place to sell the acquired assets and liabilities that comprised two of EHT's subsidiaries, Emerald Health Therapeutics Canada, Inc. ("EHTC") and VDL. As of December 31, 2024 the Company has divested both of EHT's former operating entities, and the divestiture of substantially all of EHT's assets, including the real estate held by AVI.

Sale of real estate

The wind down of EHT's operations included the disposition of real estate held by AVI (the "AVI building"). At the time of the Company’s acquisition of EHT on November 10, 2022 (the “EHT Acquisition”), none of the purchase consideration was allocated to the fair value of the AVI building. As a result of the sale of the AVI building, for the year ended December 31, 2024, the Company recorded a gain of $1,145,141 as a Gain from Asset Sales within the Other Income and Expense section of the Company's Consolidated Statements of Operations.

Divestiture of VDL, Release and Discharge Agreement

On July 17, 2024, the Company entered into a transaction, release and discharge agreement with the purchaser of Verdelite Sciences, Inc. ("VDL"). Under the transaction, release and discharge agreement, the purchase price of VDL was adjusted in exchange for a full release of any future claims by VDL against the Company. As part of the agreement, the parties agreed to a reduced installment payment schedule for the remaining aggregate balance of the purchase price of $2,047,080 through December 2027. The remainder of the purchase price receivable bears interest at 8%. Upon signing the transaction, release and discharge agreement, the Company recorded $360,750 and $213,404 as a Gain from Asset Sales within the Other Income and

Expense section of the Company's Consolidated Statement of Operations for twelve months ended December 31, 2025 and 2024, respectively.

5. Prepaid Expenses, Other Current Assets, Property and Equipment and Other Current Liabilities

Prepaid expenses consist of the following:

Other current assets consist of the following:

Property and equipment, net consists of the following:

Depreciation and amortization expense for the twelve months ended December 31, 2025 and twelve months ended December 31, 2024 was $540,135 and $203,757, respectively.

Other current liabilities consist of the following:

6. Warrants

There are significant judgements and estimates inherent in the determination of the fair value of the Company’s warrants. These judgements and estimates include assumptions regarding the Company’s future operating performance and the determination of the appropriate valuation methods. If the Company had made different assumptions, the fair value of the warrants could have been significantly different (See Note 2).

Warrants

Warrants vested and outstanding as of December 31, 2025 are summarized as follows:

As of December 31, 2025, all of the Company's warrants are fully vested.

January 2024 Pre-Funded Warrants

In connection with the January 2024 PIPE Financing (as defined in Note 8), the Company issued the Pre-Funded Warrants. The Pre-Funded Warrants have an exercise price of $0.001 per share, and were exercisable immediately upon issuance until exercised in full. The gross proceeds from the issuance of these Pre-Funded Warrants was $22,991,015. The Company determined that the Pre-Funded Warrants are freestanding instruments that do not meet the definition of a liability or derivative. The Pre-Funded Warrants are indexed to the Company’s common stock and meet all other conditions for equity classification. Accordingly, the Pre-Funded Warrants are classified as equity and are accounted for as a component of additional paid-in capital at the time issued. The Company also determined that the Pre-Funded Warrants should be included in the determination of basic and diluted earnings per share.

7. Debt

Convertible Note - Related Party

On August 15, 2023, the Company entered into a Secured Note and Warrant Purchase Agreement with MFDI, LLC (“MFDI”), pursuant to which the Company issued to MFDI a $5,000,000 secured convertible promissory note (the "Convertible Note") and a warrant to purchase 340,000 shares of common stock on August 18, 2023 . The Convertible Note accrued interest at a rate of 10% per annum and had a fixed conversion price at $5.16.

On August 8, 2024, MFDI exercised the conversion option under the Convertible Note and converted the full principal balance. This conversion resulted in the issuance of 968,973 shares of the Company's common stock and the payment of accrued interest in cash.

In the original accounting for the Convertible Note, the Company allocated $4,068,424 in proceeds to the debt host and $931,576 in proceeds to the freestanding warrants based on relative fair value. The debt discounts of $931,576 and $26,316 related to the warrants, and debt issuance costs, respectively, were amortized over the term of the Convertible Note using the effective interest rate method. Amortization of the debt discount was recognized as non-cash interest expense in Other expense within the Consolidated Statements of Operations.

Accrued interest on the Convertible Note was payable quarterly within 30 days of the last day of each calendar quarter. The debt discounts related to the warrants, and debt issuance costs, were amortized over the term of the Convertible Note using the effective interest rate method. Amortization of the debt discount is recognized as non-cash interest expense in Other (income) expense within the Consolidated Statements of Operations. Through the date of conversion, the Convertible Note is classified as Level 2 of the fair value hierarchy model based on market prices that can be corroborated with observable market data for the Company's common stock.

For the year ended December 31, 2024, the effective interest rate on the Convertible Note was 31.39%.

Interest Expense

There wasno interest expense in 2025. The Company’s interest expense for 2024 consists of the following:

8. Stockholders’ Equity and Capitalization

The January 2024 PIPE Financing was priced at $2.31 per common share and $2.30 per Pre-Funded Warrant based on the 5-day average share price preceding January 29, 2024. The Pre-Funded Warrants are exercisable at any time for an exercise price of $0.001.

In connection with the January 2024 PIPE Financing, the Company incurred $3,823,752 in direct equity issuance costs for net proceeds of $46,167,258.

March 2024 PIPE Financing

On March 11, 2024, the Company entered into a Securities Purchase Agreement with certain institutional investors, pursuant to which on March 13, 2024, the Company issued an aggregate of 4,000,000 shares of common stock (the "March 2024 PIPE Financing") for an aggregate purchase price of $40,000,000. The March 2024 PIPE Financing was priced at $10.00 per common share.

In connection with the March 2024 PIPE Financing, the Company incurred $2,610,695 in direct equity issuance costs for net proceeds of approximately $37,389,305.

Convertible Note - Related Party

The 2014 Plan authorizes the issuance of awards including stock options, stock appreciation rights, restricted stock, stock units and performance units to employees, directors, and consultants of the Company. On June 14, 2022, the Board approved the 2014 Amended and Restated Omnibus Incentive Plan (the “2014 Amended and Restated Plan”) which replaced the 2014 Plan in its entirety. On September 29, 2023, the Board and Majority Stockholders adopted and approved Amendment No. 1 to the 2014 Amended and Restated Plan. Amendment No. 1 to the 2014 Amended and Restated Plan became effective on November 6, 2023. On October 22, 2024, the second amendment and restatement of the Company's 2014 Amended and Restated Plan was approved to increase the number of shares of the Company's common stock issuable thereunder by 1,535,655 to increase the number of incentive stock options that may be granted thereunder to 4,000,000, extend the expiration date of the plan to September 10, 2034, update the name of the plan to the “Skye Bioscience, Inc. Amended and Restated Omnibus Incentive Plan” and make certain administrative amendments (as so amended and restated, the "Amended and Restated Plan").

The Amended and Restated Plan, among other things, provides that each January 1 beginning in 2023 and ending on (and including) January 1, 2032 the number of shares will increase by 5% of the outstanding shares of common stock as of the prior December 31, unless the Board of Directors of the Company decides to a lesser increase.

As of December 31, 2025, the shares available for future grant under the Amended and Restated Plan are as follows:

2024 Inducement Equity Incentive Plan

On July 2, 2024, the Board adopted the Skye Bioscience, Inc. 2024 Inducement Equity Incentive Plan (as amended and restated, the "Inducement Plan"). The Inducement Plan was adopted in order to grant share-based awards to newly hired employees as an inducement to join the Company. The terms of the Inducement Plan are substantially similar to the terms of the Company’s 2014 Amended and Restated Plan with the exception that awards may only be made to an employee who has not previously been an employee or member of the Board of Directors of the Company if the award is in connection with commencement of employment. The Company has reserved 600,000 shares of the Company’s common stock for issuance pursuant to awards granted under the Inducement Plan.

As of December 31, 2025, the shares available for future grant under the Amended and Restated Plan are as follows:

Stock Options

Options granted under the Company's equity incentive plans expire no later thanten years from the date of grant. Options granted under the Company's equity incentive plans may be either incentive or non-qualified stock options. For incentive and non-qualified stock option grants, the option price shall be at least 100% of the fair value on the date of grants, as determined by the Company’s Board of Directors. If at any time the Company grants an option, and the optionee directly or by attribution owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, the option price shall be at least 110% of the fair value and shall not be exercisable more than five years after the date of grant. The shares issued generally vest over a period ofone tofour years from the date of grant.

The following is a summary of option activities under the Company’s Amended and Restated Plan and the Inducement Plan for the year ended December 31, 2025:

*The aggregate intrinsic value is the sum of the amounts by which the quoted market price of the Company’s stock exceeded the exercise price of the stock options at December 31, 2025 for those stock options for which the quoted market price was in excess of the exercise price ("in-the-money options").

The weighted-average grant-date fair value of stock options granted for the years ended December 31, 2025 and 2024, was $2.09 and $6.04, respectively. The total fair value of the stock options that vested during the years ended December 31, 2025 and 2024 was $5,655,038 and $4,034,671, respectively.

The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option-pricing model under the following assumptions:

Restricted Stock Units

On February 29, 2024, the Company granted restricted stock units ("RSUs") to its executive management team and to certain members of the Board with market-based vesting conditions. The RSUs are eligible to vest subject to the achievement and attainment of certain market capitalization target goals and share price targets (market-based vesting conditions). The Company used the Monte Carlo Simulation model to evaluate the derived service period and fair value of awards with market and performance conditions, including assumptions of historical volatility and risk-free interest rate commensurate with the vesting term.

The fair value of the Company's market-based RSUs were estimated on the date of grant under the following assumptions:

On August 22, 2024, the Board approved a modification to the terms of the RSUs issued on August 25, 2023, and September 29, 2023 to its executive management team and to a member of the Board. The vesting condition was modified from a performance-based condition to a market-based condition. Since the performance condition under the original award was improbable of being met at the time of the modification, no expense was previously recognized. Therefore, on the modification date, the Company established a new fair value and will recognize the expense over the derived service period. The Company used the Monte Carlo Simulation model to evaluate the derived service period and fair value of the awards.

The fair value of the Company's market-based RSUs were estimated on the modification date under the following assumptions:

The following is a summary of restricted stock unit activity during the year ended December 31, 2025:

The Company used the Monte Carlo Simulation model to evaluate the derived service period and fair value of awards with market and performance conditions, including assumptions of historical volatility and risk-free interest rate commensurate with the vesting term.

Stock Compensation Adjustments Related to Board Member Resignations

On July 2, 2024, the Board accepted the resignations of several Board members effective August 1, 2024. Concurrently, the Board approved a modification to the option awards granted such Board members, which modification accelerated the vesting of all unvested options as of the resignation date and extended the post-termination exercise period to December 31, 2025. As a result of the modification, the Company recognized $274,019 in incremental stock compensation expense during the year ended December 31, 2024.

The Company recognizes stock-based compensation expense using the straight-line method over the requisite service period. The Company recognized stock-based compensation expense, including compensation expense for warrants with vesting provisions issued to a service provider (Note 6), and the RSUs discussed above, in its Consolidated Statements of Operations as follows:

The total amount of unrecognized compensation cost was $10,276,636 as of December 31, 2025. This amount will be recognized over a weighted-average period of 2.5 years.

2022 Employee Stock Purchase Plan

In June 2022, the Board approved the 2022 Employee Stock Purchase Plan (the "ESPP"), under which the Company may offer eligible employees the option to purchase common stock at a 15% discount to the lower of the market value of the stock at the beginning or end of each participation period under the terms of the ESPP. Total individual purchases in any year are limited to 15% of compensation. The ESPP was approved by the Company's stockholders on September 30, 2022. As of December 31, 2025,18,461 shares were issued under the ESPP. The compensation expense, computed using the Black-Scholes model was immaterial.

10. Loss Per Share of Common Stock

The following tables are a reconciliation of the numerators and denominators used in the calculation of basic and diluted net loss per share computations:

The following outstanding shares of common stock equivalents were excluded from the computation of diluted net loss per share of common stock for the periods presented because including them would have been anti-dilutive:

11. Income Taxes

The components of loss before the income tax provision consist of the following:

The components of the income tax expense consisted of the following:

The Company is subject to taxation in the United States, various states, Australia, and Canada. The Company’s tax years for 2022 (federal), 2021 (States), 2021 (Australia) and 2021 (Canada) and forward are subject to examination by the United States, state, Australian, and Canadian tax authorities. However, to the extent allowed by law, the taxing authorities may have the right to examine periods where NOLs and credits were generated and carried forward and make adjustments up to the amount of the NOL and credit carryforwards. The Company is not currently under examination by any jurisdiction.

At December 31, 2025, the Company had federal and state NOLs aggregating $159,062,533 and $188,066,339, respectively. If not used, $46,622,953 of Federal NOLs and $188,066,339 of state NOLs will begin to expire in 2031, $112,439,580 of federal NOLs will carry forward indefinitely subject to an 80% limitation against taxable income. At December 31, 2025, the Company had Australia NOLs aggregating $453,074 which do not expire and $43,879,070 of Canadian NOLS which begin to expire in 2026.

At December 31, 2025, the Company had Canadian capital loss carryforwards of approximately $35,277,475 which may be carried forward indefinitely.

At December 31, 2025, the Company had federal and California research credit carryforwards of $6,156,218 and $2,445,548, respectively. The federal research credit carry forwards will begin to expire in 2027, unless previously utilized. The California research credits will carry forward indefinitely. The Company’s NOLs and research credit carryforwards are subject to a reserve. Additionally, the Company had Canadian SR&ED credits as of December 31, 2025 of $909,791 which may be carried forward indefinitely.

Utilization of the domestic NOL's and research credits could be subject to a substantial annual limitation due to ownership change limitations that may have occurred, or that could occur in the future, as required by Section 382 and 383 of the Internal Revenue Code of 1986, as amended (the Code), as well as similar state provisions. These ownership changes may limit the amount of NOLs and credits that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders.

Upon the occurrence of an ownership change under Section 382 as outlined above, utilization of the NOLs and credits are subject to an annual limitation under Section 382 of the Code, which is determined by first multiplying the value of the Company’s stock at the time of the ownership change by the applicable long-term, tax-exempt rate, and then could be subject to additional adjustments, as required. Any limitation may result in expiration of a portion of the NOLs and credits before utilization. While the Company has not performed a Section 382 study, multiple ownership changes may have already occurred as the Company raised capital through the issuance of stock. However, due to the existence of the valuation allowance for deferred tax assets, any potential change in ownership will not impact the Company’s effective tax rate.

The tax effects of temporary differences and carryforwards that give rise to significant portions of the deferred income tax assets as of December 31, 2025 and December 31, 2024 are as follows:

A reconciliation of the provision for income taxes to the amount computed by applying the 21% statutory U.S. federal income tax rate to income (loss) from continuing operations before income taxes after the adoption of ASU 2023-09 is as follows:

[a] The State of California comprises greater than 50 percent of the state tax expense for the period ended December 31, 2025.

The provision for income taxes on earnings subject to income taxes differs from the statutory Federal rate at December 31, 2024, due to the following:

The Company records a valuation allowance against deferred tax assets to the extent that it is more likely than not that some portion, or all of, the deferred tax assets will not be realized. Due to the substantial doubt related to the Company's ability to utilize its deferred tax assets, a valuation allowance for the full amount of the deferred tax assets has been established at December 31, 2025. During the year ended December 31, 2025, the valuation allowance increased by $6,591,212.

Under the FASB’s accounting guidance related to income tax positions, among other things, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, the guidance provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

A reconciliation of the beginning and ending amounts of unrecognized tax positions are as follows:

If recognized, none of the unrecognized tax positions would impact the Company’s income tax benefit or effective tax rate as long as the Company’s net deferred tax assets remain subject to a full valuation allowance.

The Company hadno accrual for interest or penalties on the Company’s Consolidated Balance Sheets at December 31, 2025 and 2024 and hasnot recognized interest and/or penalties in the Consolidated Statements of Operations for the years then ended.

12. Commitments and Contingencies

Office Leases

The Company leases office space for its corporate headquarters, located at 11250 El Camino Real, Suite 100 San Diego, California 92130. The original lease term was effective from September 1, 2021 through October 31, 2023 and contained a renewal option for atwo-year extension after the current expiration date. At the commencement date, the Company did not expect to exercise the renewal option, and has therefore excluded the option from the calculation of the right of use asset and lease liability. The lease provides fortwo months of rent abatement and the initial monthly rent is $8,067 per month with annual increases of 3% commencing on November 1, 2022. The lease included non-lease components (i.e., property management costs) that are paid separately from rent, based on actual costs incurred, and therefore were not included in the right-of-use asset and lease liability but are reflected as an expense in the period incurred. In calculating the present value of the lease payments, the Company has elected to utilize its incremental borrowing rate based on the lease term.

The Company entered into an amended and restated lease agreement on June 27, 2023 for its corporate headquarters, extending the lease term to 36 months, retroactive to September 1, 2021 through October 31, 2026. The Company treated the amended and restated lease agreement as a single modified lease.

On September 25, 2024, the Company entered into a new lease agreement for approximately 2,077 square feet of office space located at 632 Commercial Street, 5th Floor, San Francisco, California 94111. The lease has a term ofthree years and two months, beginning on October 01, 2024, with a monthly rent of $9,000 and annual increases of 3%. This office space will support the Company's continued growth and operational needs as the Company expands its development activities. In calculating the present value of the lease payments, the Company has elected to utilize its incremental borrowing rate based on the lease term.

For the years ended December 31, 2025 and 2024, lease expense comprised of $207,400 and $130,658, respectively in lease cost from the Company's non-cancellable operating leases.

The remaining lease term and discount rate related to the operating lease are presented in the following table:

Future minimum lease payments as of December 31, 2025 are presented in the following table:

General Litigation and Disputes

From time to time, in the normal course of operations, the Company may be a party to litigation and other dispute matters and claims. Litigation can be expensive and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. An unfavorable outcome to any legal matter, if material, could have a materially adverse effect on the Company’s operations or financial position, liquidity or results of operations.

Wendy Cunning vs Skye Bioscience, Inc.

The Company is a party to a legal proceeding with a former employee alleging, among other things, wrongful termination, violation of whistleblower protections under the Sarbanes-Oxley Act of 2002, and retaliation under California law against the Company relating to certain actions and events that occurred with the Company's former management during the employee's employment term from March 2018 to July 2019. The case, entitled Wendy Cunning vs Skye Bioscience, Inc., was filed in U.S. District Court (the "District Court") for the Central District of California (the “Cunning Lawsuit”). On January 18, 2023, a jury rendered a verdict in favor of Ms. Cunning and awarded her $512,500 in economic damages (e.g., lost earnings, future earnings and interest), $840,960 in non-economic damages (e.g., emotional distress) and $3,500,000 in punitive damages. On August 2, 2023, the District Court ruled on the plaintiff's motion for attorney fees and awarded the plaintiff $1,200,008. Based on this order, the Company reduced the aggregate estimate for the legal contingency by $151,842, the difference between the attorney fees awarded by the District Court and the Company's previous estimate. On August 17, 2023, the Company obtained a stay on enforcement of the judgment in the Cunning Lawsuit by posting an appeal bond in the amount of $9,080,202.

In March of 2023, the Company appealed the judgment in the Cunning Lawsuit to the United States Court of Appeals for the Ninth District (the "Ninth Circuit"). Subsequent to quarter end, on October 22, 2024, the Ninth Circuit issued its decision in the Company's favor which vacated the judgment and remanded the case back to the District Court for a new trial. As a result, the Company recovered the $9,080,202 restriction on its cash related to the bond during the year ended December 31, 2024. The District Court has tentatively set a new trial date in March 2026.

During the year ended December 31, 2024, management revised its assumptions related to its estimate of the legal contingency and the Company reversed the accrued interest on the original judgment and recognized a gain of $4,234,717 in change in estimate for legal contingencies. As of December 31, 2025, the estimated legal contingency, including accrued legal expenses is $2,069,067.

In arriving at the conclusion that a significant portion of the estimated legal contingency should be reversed, the Company considered the following in revising its assumptions:

•Advice from external advisors including its technical accounting advisors regarding the appropriate application of GAAP and legal counsel’s advice with regard to prior experience with similar cases,

•the damages and potential attorney fee awards if the case were to be retried, including the likelihood of a subsequent loss if the Company were to be unsuccessful while giving consideration to the facts and circumstances that would be inadmissible due to the Ninth Circuit’s decision,

•the likelihood of settlement and information obtained during settlement discussions prior to the first trial,

•the Company’s possible defenses and counterclaims, and

•the case history and the amount of the prior judgment.

The final amount of the loss and loss recoveries remain uncertain. The ultimate amount of the potential loss may be significantly less than the amount of the revised legal contingency and there is no guarantee that the Company will be successful in its efforts to recover additional losses. The Company believes that it is at least reasonably possible that the estimated amount of the potential loss may change in the near term.

Securities Class Action and Derivative Lawsuit

A putative securities class action lawsuit was filed on November 17, 2025, in the United States District Court for the Southern District of California, captioned Stout v. Skye Bioscience, Inc., et al., Case No. 3:25-cv-03177-WQH. The complaint asserts that the Company and certain of the Company's executives violated Section 10(b) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and SEC Rule 10b-5, by making materially false or misleading statements related to the efficacy of and prospects for nimacimab between November 4, 2024 and October 3, 2025. The plaintiff also alleges that the Company's executives, whom they named as defendants, violated Section 20(a) of the Exchange Act. The plaintiff seeks class certification, an award of unspecified damages, an award of costs and expenses, including attorneys’ fees and expert fees, and further relief as the Court may deem just and proper. On January 16, 2026, two stockholders moved to be appointed lead plaintiff.

A putative derivative lawsuit was filed on January 29, 2026, in the United States District Court for the Southern District of California, captioned Domulot v. Dhillon et al., Case No. 3:26-cv-00600-WQH. The lawsuit asserts claims, purportedly on behalf of the Company, against certain officers and directors of the Company for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, violations of Sections 14(a) of the Exchange Act, and for contribution under Sections 10(b) and 21D of the Exchange Act based on the dissemination of allegedly false and misleading statements related to nimacimab. The plaintiff seeks unspecified damages, an award of costs and expenses, including attorneys’ fees and expert fees, and other relief, including corporate governance reforms.

License Agreement with Halozyme

On December 18, 2025, the Company entered into a Non-exclusive Collaboration and License Agreement (the “Halozyme License Agreement”) with Halozyme, Inc. (“Halozyme”).

Under the terms of the Halozyme License Agreement, Halozyme granted the Company a non-exclusive license to Halozyme’s ENHANZE® drug delivery technology for the development of a subcutaneous formulation of nimacimab (such combination, the “Product”). Halozyme will also be the Company’s exclusive supplier of clinical and commercial supplies of the API for Halozyme’s rHuPH20 bulk drug product.

Among other considerations, the Company will make milestone payments to Halozyme tied to achievement of certain development and commercialization milestone events with respect to the Product, as well as milestone payments based on achievement of certain net sales levels of the Product. The Company will also make mid-single digit royalty payments based on worldwide net sales of the Product. To date, none of such milestones has been achieved.

The Halozyme License Agreement became effective in December 2025 and, unless earlier terminated, will continue until the expiration of the royalty term for the applicable product in each country, which begins upon the first commercial sale of the product in such country and continues until the last valid patient claim covering the product in that country or the length of time specified in the Halozyme License Agreement. The Halozyme License Agreement also includes customary termination rights, representations and warranties, covenants and indemnification obligations for a transaction of this nature.

13. Segment Reporting

The Company operates inone business segment, which includes the business of research and development activities related to developing medicine for obesity and metabolic diseases. The determination of a single business segment is consistent with the consolidated financial information regularly provided to the Company’s chief operating decision maker (“CODM”). The Company’s CODM is its Chief Executive Officer, who reviews and evaluates consolidated net loss for purposes of assessing performance, making operating decisions, allocating resources, and planning and forecasting for future periods.

In addition to the significant expense categories included within consolidated net loss presented on the Company's Consolidated Statements of Operations, see below for disaggregated amounts that comprise research and development expenses which are presented to the Company's CODM for review:

(1) External clinical development expenses include expenses for clinical trial costs and clinical manufacturing, as well as costs for discovery in research and development studies.

(2) Other research and development expenses include expenses for travel and entertainment, consulting and advisory and general business expenses.

14 Subsequent Events

Subsequent to December 31, 2025, the Company granted an aggregate of 1,367,800 common stock options to members of management, employees and directors under the Amended and Restated Plan.

Concurrently, with the separation of the Company's Chief Financial Officer, on February 20, 2026 (the "Separation Date"), the Board approved a modification to the option awards granted Ms Arsenault, which extended the post-termination exercise period to the later of February 20, 2027, or ninety (90) days after the expiration of her Advisor Agreement. In addition, in the event of a change in control withinone year from the Separation Date,100% of Ms. Arsenault's equity will vest immediately prior to the consummation of such change in control.

On February 18, 2026, the Company formally requested to terminate its lease for the San Francisco office effective 60 days after the notice. As a result of this termination, the Company will derecognize a right-of-use asset and lease liability of approximately $170,000 in the first quarter of 2026. The Company has also initiated a claim for the full refund of its security deposit related to this termination.

The following exhibits are filed with this Annual Report on Form 10-K.
