Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. The Company’s significant estimates used in these consolidated financial statements include, but are not limited to, revenue recognition, fair value of stock-based compensation, and the determination of the economic useful life of depreciable property and equipment. Certain of the Company’s estimates could be affected by external conditions, including those unique to the Company and general economic conditions. It is reasonably possible that these external factors could have an effect on the Company’s estimates and could cause actual results to differ from those estimates.

Accounts Receivable. Accounts receivable are carried at their contractual amounts, less an estimated allowance for credit losses. Credit is granted in the normal course of business without collateral. The typical payment term is 30 days. Management estimates the allowance for credit losses using a loss-rate approach based on historical loss information, adjusted for management’s expectations about current and future economic conditions, as the basis to determine expected credit losses. Management exercises significant judgment in determining expected credit losses. Key inputs include macroeconomic factors, industry trends, the creditworthiness of counterparties, historical experience, the financial conditions of the customers, and the amount and age of past due accounts. Management believes that the composition of receivables at year-end is consistent with historical conditions as credit terms and practices and the client base has not changed significantly. Receivables are considered past due if full payment is not received by the contractual due date. Past due accounts are generally written off against the allowance for credit losses only after all collection

attempts have been exhausted. The allowance for credit losses was $232,206 and $203,960 as of March 31, 2026 and December 31, 2025, respectively. There were two and one customers who represented in the aggregate 25% and 12% of total accounts receivable as of March 31, 2026 and December 31, 2025, respectively.

Property and Equipment. Property and equipment are stated at cost, net of accumulated depreciation and amortization, which is recorded commencing at the in-service date using the straight-line method over the estimated useful lives of the assets, as follows: 3 to 5 years for lab, office and computer equipment, 5 to 7 years for furniture and fixtures, 10 to 15 years for building improvements, and 5 years for software. When fixed assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the statements of comprehensive loss for the respective period. Minor additions and repairs are expensed in the period incurred. Major additions and repairs which extend the useful life of existing assets are capitalized and depreciated using the straight-line method over their remaining estimated useful lives.

Major additions and repairs which extend the useful life of existing assets are capitalized and depreciated using the straight-line method over their remaining estimated useful lives.

Contingent Liabilities. The Company, from time to time, may be involved in certain legal proceedings. Based upon consultation with outside counsel handling its defense in these matters and the Company’s analysis of potential outcomes, if the Company determines that a loss arising from such matters is probable and can be reasonably estimated, an estimate of the contingent liability is recorded in its consolidated financial statements. If only a range of estimated loss can be determined, an amount within the range that, based on estimates, assumptions and judgments, reflects the most likely outcome, is recorded as a contingent liability in the consolidated financial statements. In situations where none of the estimates within the estimated range is a better estimate of probable loss than any other amount, the Company records the low end of the range. Any such accrual would be charged to expense in the appropriate period. Litigation expenses for these types of contingencies are recognized in the period in which the litigation services were provided.

Warrants. The Company classifies a warrant to purchase shares of its common stock as equity on its consolidated balance sheets as this warrant is a free-standing financial instrument that is indexed to the Company’s own stock and meets the criteria for equity classification. Each warrant is initially recorded within equity at the date of grant, net of issuance costs, and is not subsequently re-measured. Changes in the fair value of the warrant are not recognized after the initial measurement. The warrants will remain classified in equity until they are exercised or expire.

Foreign Currency Transactions and Translation. Exyn’s functional currency is the United States Dollar (“USD”) and Exyn Latam’s functional currency is the Chilean Peso (“CLP”).

For the purpose of presenting these consolidated financial statements the reporting currency is USD. The Company’s assets and liabilities are expressed in USD at the exchange rate on the balance sheet date, equity accounts are translated at historical rates, and income and expense items are translated at the weighted average exchange rate during the period. The resulting translation adjustments are reported under accumulated other comprehensive income in the stockholders’ equity section of the balance sheets.

Transactions in currencies other than the entity’s functional currency are recorded at the rates of exchange prevailing on the date of the transaction.

Exchange rate used for the translation are as follows:

Deferred Financing Costs. Deferred financing costs include debt discounts and debt issuance costs related to a recognized debt liability and are presented in the balance sheet as a direct deduction from the carrying value of the debt liability. Amortization of deferred financing costs are included as a component of interest expense. Deferred financing costs are amortized using the straight-line method over the term of the recognized debt liability which approximates the effective interest method.

Fair Value Measurements. The Company measures the fair value of financial assets and liabilities based on the guidance of ASC 820 “Fair Value Measurements and Disclosures” (“ASC 820”) which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements.

ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an 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. ASC 820 also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 describes three levels of inputs that may be used to measure fair value:

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

Level 2 — quoted prices for similar assets and liabilities in active markets or inputs that are observable

Level 3 — inputs that are unobservable (for example, cash flow modeling inputs based on assumptions)

The following table shows the fair value measurements used by level as of March 31, 2026:

​

​

The following table shows the fair value measurements used by level as of December 31, 2025:

​

​

The carrying amounts of the Company’s financial instruments, such as cash, accounts receivable, accounts payable and other current liabilities approximate fair values due to the short-term nature of these instruments The estimated fair value of the Company’s long-term debt approximates the carrying value of these instruments, due to the interest rates on this debt approximating current market interest rates.

As of December 31, 2025, the Company issued SAFEs, with gross proceeds totaling $4,700,000. The Company did not issue any additional SAFEs in the three months ended March 31, 2026.

Measurement

As there are no quoted prices or observable market inputs available for these instruments, the SAFEs are classified within Level 3 of the fair value hierarchy. The Company engaged a third-party valuation specialist to assist in the estimation of fair value at each reporting date using a Probability-Weighted Expected Return Method to probability-weight discrete outcomes (including equity

financing, liquidity event, termination, and dissolution) and an Option Pricing Model to value the option-like conversion features within the applicable scenarios.

For the April 5, 2025 ($1,500,000 SAFE) issuance, the significant unobservable inputs used in the Level 3 valuation include:

​

​

For the August 1, 2025 ($3,000,000 SAFE) and December 1, 2025 ($100,000 SAFEs each) issuances, the significant unobservable inputs used in the Level 3 valuation include the inputs set forth in the table below. Because the December 2025 SAFEs had terms identical to the August 1, 2025 SAFE and management concluded there were no significant changes in the Company’s facts and circumstances or key valuation drivers between issuance dates, the Company applied the same valuation methodology and significant unobservable inputs used for the August 1, 2025 issuance to estimate the initial fair values of the December 2025 SAFEs.

​

​

The following table summarizes the changes in SAFE liabilities for the three months ended March 31, 2026:

​

​

As a Level 3 fair value measurement, the estimated fair value of the SAFE liabilities is sensitive to changes in significant unobservable inputs, including the assumed probability and timing of future equity financings and liquidity events, the Company’s implied equity value, volatility, and the discount rate. Changes in these inputs may increase or decrease the estimated fair value depending on their effect on the probability-weighted expected payoff to SAFE holders. For example, a decrease in the discount rate generally increases the estimated fair value; however, changes in event probabilities or volatility may have different directional effects depending on the contractual terms and modeled outcomes.

During the year ended December 31, 2025, the Company issued SAFEs, with gross proceeds totaling $4,700,000.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Liability classification

The Company evaluates its SAFEs for equity classification and has concluded the instruments do not qualify for equity classification under ASC 815-40. Accordingly, the SAFEs are classified as liabilities and remeasured at fair value each reporting date, with changes in fair value recognized in earnings. See Note 10, SAFE Liabilities, for additional information.

Measurement

As there are no quoted prices or observable market inputs available for these instruments, the SAFEs are classified within Level 3 of the fair value hierarchy. The Company engaged a third-party valuation specialist to assist in the estimation of fair value at each reporting date using a Probability-Weighted Expected Return Method (“PWERM”) to probability-weight discrete outcomes (including equity financing, liquidity event, termination, and dissolution) and an Option Pricing Model (“OPM”) to value the option-like conversion features within the applicable scenarios.

The supplemental reconciliation above is provided to bridge cash proceeds to the initial and subsequent fair value measurements and to reconcile to the income statement caption Noncash Change in Fair Value of SAFE Liabilities. For the year ended December 31, 2025, the Company recognized a total noncash loss of $2,187,000, consisting of $1,318,000 attributable to initial recognition of SAFEs issued during the year where the initial fair value exceeded cash proceeds and $869,000 attributable to changes in fair value subsequent to issuance through December 31, 2025.

As a Level 3 fair value measurement, the estimated fair value of the SAFE liabilities is sensitive to changes in significant unobservable inputs, including the assumed probability and timing of future equity financings and liquidity events, the Company’s implied equity value, volatility, and the discount rate. Changes in these inputs may increase or decrease the estimated fair value depending on their effect on the probability- weighted expected payoff to SAFE holders. For example, a decrease in the discount rate generally increases the estimated fair value; however, changes in event probabilities or volatility may have different directional effects depending on the contractual terms and modeled outcomes.

Leases. The Company leases certain facilities and office space. Lease assets and lease liabilities are recognized at the commencement of an arrangement where it is determined at inception that a lease exists. Lease assets represent the right to use an

underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. These assets and liabilities are initially recognized based on the present value of lease payments over the lease term calculated using an incremental borrowing rate generally applicable to the location of the lease asset, unless the implicit rate is readily determinable. Lease assets also include any upfront lease payments made and exclude lease incentives. Lease terms include options to extend or terminate the lease when it is reasonably certain that those options will be exercised. The Company has operating lease arrangements with lease and non-lease components. The non-lease components in these arrangements are not significant when compared to the lease components. For all operating leases, the Company accounts for the lease and non-lease components as a single component. In the calculation of the lease asset and corresponding liability.

Variable lease payments are generally expensed as incurred. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and the expense for these short-term leases is recognized on a straight-line basis over the lease term. The depreciable life of lease assets and leasehold improvements is limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

Segment Reporting. The Company uses “the management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer (“CEO”) of the Company, who reviews operating results to make decisions about allocating resources and assessing performance for the entire Company. The Company’s primary revenue stream includes the sale of aerial robotic systems and related software solutions that enable data collection, mapping, and inspection. Based on the CODM’s evaluation and internal reporting, the Company has one reportable segment: Aerial Robotic Systems.
