Notes to Consolidated Financial Statements

Note 1 — Description of Organization and Business Operations

Description of Business

Rain Enhancement Technologies Holdco, Inc. (the “Company” or “Holdco”) was formed in Massachusetts to develop, improve and commercialize atmospheric enhancement by ionization (AEI) technology. The Company is developing improvements to existing AEI technologies by leveraging robust measurement tools, including software monitoring technology, machine learning, rain gauges, and weather stations.

Business Combination Agreement

On December 31, 2024 (the “Closing Date”), Holdco, Coliseum Acquisition Corp, a Cayman Islands exempted company (“Coliseum”), Rain Enhancement Technologies, Inc., a Massachusetts corporation (“RET”), Rainwater Merger Sub 1, Inc., a Cayman Islands exempted company and wholly-owned subsidiary of Holdco (“Merger Sub 1”), and Rainwater Merger Sub 2A, Inc., a Massachusetts corporation and wholly-owned subsidiary of Coliseum (“Merger Sub 2”) consummated the previously announced business combination (the “Business Combination”) pursuant to the terms of the Business Combination Agreement, dated as of June 25, 2024 (as amended on August 22, 2024, the “Business Combination Agreement”).

Pursuant to the Business Combination Agreement, on the Closing Date, (i) Coliseum merged with and into Merger Sub 1, with Merger Sub 1 as the surviving company of such merger (the “SPAC Merger”) and (ii) following the SPAC Merger and as a part of the same overall transaction, Merger Sub 2 merged with and into RET, with RET as the surviving entity of such merger (the “Company Merger” and, together with the SPAC Merger, the “Mergers”), and, after giving effect to such Mergers, each of Merger Sub 1 and RET became a wholly owned subsidiary of Holdco (the time that the SPAC Merger became effective being referred to as the “SPAC Merger Effective Time,” the time that the Company Merger became effective being referred to as the “Company Merger Effective Time,” and the time after which both Mergers became effective being referred to as the “Closing”). Following the Closing, Holdco holds all of the equity interests of RET and Merger Sub 1.

The Business Combination was treated as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Coliseum was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of RET issuing stock for the net assets of Coliseum, accompanied by a recapitalization. The net assets of Coliseum were stated at historical cost, with no goodwill or other intangible assets recorded.

The Company’s common stock and warrants commenced trading on the Nasdaq Stock Market LLC under the symbols “RAIN” and “RAINW”, respectively, on January 2, 2025. Refer to Note 4,*Business Combination,*for additional details.

Recent Developments

Nasdaq Compliance Notices

On February 18, 2025, the Company received written notice (the “MVLS Notice”) from the Listing Qualifications Staff (“Staff”) of the Nasdaq Stock Market LLC (“Nasdaq”) which notified the Company that, for the 30 consecutive business days ended February 14, 2025, the Company’s market value of listed securities (“MVLS”) closed below the $50,000,000 MVLS threshold required for continued listing on the Nasdaq Global Market under Nasdaq Listing Rule 5450(b)(2)(A) (the “MVLS Rule”). Also on February 18, 2025, the Company received written notice (the “MVPHS Notice”) from the Staff that for the 30 consecutive business days ended February 14, 2025, the Company’s market value of publicly held securities (“MVPHS”) closed below the $15,000,000 MVPHS threshold required for continued listing on Nasdaq under Nasdaq Listing Rule 5450(b)(2)C) (the “MVPHS Rule”).

On August 19, 2025, the Company received a notice (the “Notice”) from the Staff indicating that the Company had not regained compliance with either the MVLS Rule or the MVPHS Rule and, unless the Company timely requests a hearing before the Nasdaq Hearings Panel (the “Panel”), the Company’s securities would be subject to suspension and delisting from The Nasdaq Global Market. We timely submitted its request for a hearing before the Panel on August 21, 2025.

As part of the compliance plan submitted to the Panel, the Company requested a transfer of its listing from the Nasdaq Global Market to the Nasdaq Capital Market. A hearing before the Panel was held on September 18, 2025 and on October 14, 2025, the Panel granted the Company’s request for continued listing on Nasdaq, subject to the Company’s timely application to transfer its listing from the Nasdaq Global Market to the Nasdaq Capital Market and demonstrating compliance with the applicable listing requirements. We completed the transfer to the Nasdaq Capital Market and demonstrated compliance with the applicable listing rules. Nasdaq subsequently confirmed that we had regained compliance with its previously disclosed deficiencies,

The Company’s Class A common stock and warrants will continue to trade under the symbol “RAIN” and “RAINW”, respectively.

On February 18, 2026, the Company received an additional written notice from Nasdaq indicating that, for the 30 consecutive business days ended February 17, 2026, its MVLS had closed below the $35,000,000 minimum required for continued listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(2). In accordance with Nasdaq rules, the Company has 180 calendar days, or until August 17, 2026, to regain compliance with the MVLS requirement. To regain compliance, its MVLS must close at or above $35,000,000 for a minimum often consecutive business days during this compliance period. The Company intends to monitor its MVLS and evaluate available options to regain compliance with Nasdaq listing standards; however, there can be no assurance that it will regain or maintain compliance within the applicable compliance period.

Going Concern Consideration

In connection with the Company’s assessment of going concern considerations in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Classification (“ASC”) Subtopic 205-40, “Presentation of Financial Statements - Going Concern,” the Company evaluates whether there are conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. This assessment considers the Company’s current cash position, projected cash requirements, and its ability to obtain additional funding.

As of December 31, 2025, the Company had approximately $214,000 in cash and had a working capital deficit of approximately $13.0 million. The Company expects to continue incurring expenses and losses as it scales its operations and begins to generate revenue. The Company has historically funded its operations primarily through related-party financing arrangements, including borrowings under its LOC (as defined in Note 7). As of December 31, 2025, the Company had drawn substantially all available amounts under this facility. While the Company expects to continue relying on these financing sources and projected cash flows from operations, its limited operating history and continuing operating losses raise substantial doubt about its ability to continue as a going concern.

Management’s plans to address this uncertainty include continued support from related parties, seeking additional financing through debt, equity, or a combination of both, and pursuing commercial opportunities for installation and service agreements. However, there is no assurance that such funding will be available on acceptable terms, or at all.

Accordingly, management has determined that the Company does not have sufficient liquidity to meet its anticipated obligations over the next year from the date of issuance of these consolidated financial statements. The consolidated financial statements included in this Annual Report do not include any adjustments that might result from the outcome of this uncertainty.

Risks and Uncertainties

Various macroeconomic, geopolitical and regulatory uncertainties and challenges pose risks to economic conditions in the U.S. and globally, including, among others, inflationary pressures; supply chain disruptions; increased cyberattacks against U.S. companies and critical infrastructure; changes to trade and tariff, immigration, energy and other policies resulting from governmental actions; changes in interest rate policies; the Russia-Ukraine war; conflicts in the Middle East including recent military confrontations involving the United States, Israel and Iran and related regional instability; and economic conditions and tensions involving China and other global powers.

Global geopolitical tensions and military conflicts have increased in recent years. These conflicts have contributed to volatility in global financial markets, disruptions in energy and commodity markets, and risks to global supply chains and international trade routes.

Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions, and subsequent sanctions or related actions, instability, volatility or lack of liquidity in the financial markets, could adversely affect the Company’s business, financial and operating results.

Note 2 — Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements

The Company identified an error related to the accounting for financed insurance premiums. The Company obtained its liability insurance coverage for directors and officers (“D&O”) effective December 31, 2024. On January 2, 2025, the Company executed a financing agreement with a financing company to finance $640,000 of the premium. On January 30, 2025, the down payment and first installment was paid. The Company should have recorded the premium financing agreement as liabilities, with an offset to prepaid expenses, upon its execution. The error was identified as part of the preparation of the Company’s consolidated financial statements for the year ended December 31, 2025. The misstatement affected the presentation of prepaid expenses and related liabilities on the Company’s balance sheets as of March 31, 2025 and June 30, 2025. Therefore, the audit committee of the board of directors, in consultation with management, concluded that the Company’s previously issued unaudited condensed consolidated financial statements for each of the quarters ended March 31, 2025 and June 30, 2025 (the “Affected Periods”) should not be relied upon and should be restated to reflect the correct presentation on the balance sheets.

Impact of the Restatement

The impact of the restatement on the unaudited condensed consolidated financial statements for the Affected Periods is presented below.

The following tables contain unaudited condensed consolidated quarterly financial information for the quarterly periods ended March 31, 2025 and June 30, 2025 that have been updated to reflect the restatements of the Company’s consolidated financial statements as described above. The restatements only affected the balance sheets and had no impact on the statement of operations or the statements of changes in stockholders’ deficit or cash flows. The Company has not amended its previously filed Quarterly Reports on Form 10-Q for the Affected Periods. The financial information that had been previously filed or otherwise reported for the Affected Periods is superseded by the information in this Annual Report, and the financial statements and related financial information for the Affected Periods contained in such previously filed reports should no longer be relied upon.

Note 3 — Summary of Significant Accounting Policies

Basis of Consolidation and Presentation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries: Rainwater Acquisition Corp (f.k.a Merger Sub 1) and RET. All significant intercompany accounts and transactions have been eliminated.

The consolidated financial statements are presented in U.S. dollars in conformity 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 (the “SEC”).

Certain prior period amounts have been reclassified to conform to the current period presentation, including reclassifications between property and equipment and construction in progress. These reclassifications had no impact on total assets, total liabilities, stockholders’ deficit, net loss, or cash flows as previously reported.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets, liabilities and expenses and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities at the date of purchase of three months or less to be cash equivalents. Cash and cash equivalents are stated at fair value and may include money market funds, U.S. Treasury and U.S. government-sponsored agency securities, corporate debt, commercial paper, and certificates of deposit. The Company hadno cash equivalents as of December 31, 2025 and 2024.

Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the accompanying consolidated balance sheets, either because of the short-term nature of the instruments or because the instrument is recognized at fair value.

Fair Value Measurements

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

●Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets;
●Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and
●Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

Derivative Financial Instruments

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to FASB ASC Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”) and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The assessment considers whether the financial instruments are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the financial instruments meet all of the requirements for equity classification under ASC 815, including whether the financial instruments are indexed to the Company’s own ordinary shares, among other conditions for equity classification.

Foreign Currency Translation and Transactions

The U.S. dollar is the Company’s functional currency. Transactions denominated in currency other than the Company’s functional currency are recorded upon initial recognition at the exchange rate on the date of the transaction. After initial recognition, monetary assets and liabilities denominated in foreign currency are remeasured at each reporting date into the foreign currency at the exchange rate on that date. Exchange rate differences, other than those accounted for as hedging transactions, are recognized as foreign currency transaction gain or loss included in the Company’s consolidated statements of operations within the general and administrative expenses.

During the years ended December 31, 2025 and 2024, the only foreign currency transaction the Company incurred was the amount paid to its senior technology advisor in Australian Dollars. The amount of these foreign currency payments was translated into U.S. dollars.

Equipment and Construction In-Process Equipment

The Company capitalizes its cost to build its rainfall ionization equipment (the “Equipment”), including materials and allocated labor costs directly attributable to the construction of the Equipment. Upon the installation of the Equipment, the Company transfers its capitalized cost from Construction in-process to Equipment. Equipment that has been completed but has not yet been installed or otherwise placed into service remains within construction in-process Equipment and is not depreciated until transferred into Equipment and placed into service. Construction in-process equipment includes costs for units under construction or in transit prior to installation.

In July 2024, the Company completed its building process for its two initial units. In October and December 2025, the Company completed building another 7 units. All of these units were included in the Construction in-process equipment in the accompanying consolidated balance sheets until they were placed in services.

Depreciation begins when the equipment is placed into service and is recorded on a straight-line basis over the estimated useful life of the assets, which the Company currently estimates to be 10 years. At the time of retirement or other disposition of the Equipment, the cost and accumulated depreciation will be removed from the accounts and the resulting gain or loss, if any, will be reflected in operations.

As of December 31, 2024, no Equipment has been placed in service. During the year ended December 31, 2025, the Company placed two systems into service and was moved from Construction in-process into Equipment. The Company recorded approximately $7,000 of depreciation expense related to those systems in the accompanying consolidated statements of operations. The remaining seven completed units were not placed in service and remained included in the Construction in-process as of December 31, 2025.

Installation costs represent expenses incurred in connection with the installation of the Company’s AEI systems deployed in pilot installations and evaluation projects. These costs are expensed as incurred and primarily consist of labor, travel, site preparation and related operational expenses associated with system deployment and testing. As the Company is currently in an early stage of commercial deployment, certain installation activities may occur prior to the execution of revenue-generating customer agreements.

Equipment, including construction in-process equipment, as of December 31, 2025 and 2024 was comprised of the following:

December 31,
20252024
Equipment:
Rainfall ionization equipment and systems, in-process$987,805$414,034
Rainfall ionization equipment and systems, completed414,034-
Rainfall ionization equipment and systems, accumulated depreciation(6,901)-
Total$1,394,938$414,034

Recognized intangible assets have finite lives and include acquired licenses for market-ready technology and designs of weather modification and rainfall ionization equipment. Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses.

Intangible assets with finite lives are amortized using the straight-line method over the estimated useful economic life. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to modify the amortization period or method, as appropriate, and are treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the statements of operations and in the expense category that is consistent with the function of the intangible assets.

Intangible assets with finite lives are tested for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. These conditions may include a change in the extent or manner in which the asset is being used or a change in future operations. The Company assesses the recoverability of the carrying amount by preparing estimates of future revenue, margins, and cash flows. If the sum of expected future cash flows (undiscounted and without interest charges) is less than the carrying amount, an impairment loss is recognized. The impairment loss recognized is the amount by which the carrying amount exceeds the fair value of the asset. Fair value of these assets may be determined by a variety of methodologies, including discounted cash flow models. No impairment was recorded for the years ended December 31, 2025 or 2024.

As of December 31, 2025 and 2024, the Company didnot have any intangible assets with indefinite useful lives.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development expenses consist of expenditures incurred in the discovery and development of new products, processes or services and the improvement of existing products, processes or services and the cost of conducting trials.

Leases

The Company follows the guidance of ASC 842, “Leases,” which requires an entity to recognize a right-of-use (“ROU”) asset and a lease liability for virtually all leases. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company determines the present value of lease payments utilizing its incremental borrowing rate, as the implicit rate of interest in the respective leases is not readily determinable. The Company’s incremental borrowing rate is a hypothetical rate based on its understanding of what its credit rating would be.

The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have a lease term of 12 months or less. The Company recognizes the lease payments associated with its short-term land leases as an expense on a straight-line basis over the lease term.

Stock-based Compensation

The Company’s policy is to account for stock-based compensation expense in accordance with FASB ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation associated with equity awards is measured at fair value upon the grant date and recognized over the requisite service period. To the extent a stock-based award is subject to performance conditions, the amount of expense recorded in a given period, if any, reflects an assessment of the probability of achieving such performance condition, with compensation recognized once the event is deemed probable to occur. Forfeitures are recognized as incurred.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the consolidated financial statements carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC 740 prescribes a recognition threshold and a measurement attribute for the consolidated financial statements recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There wereno unrecognized tax benefits as of December 31, 2025 and 2024. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of December 31, 2025 and 2024. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major tax authorities since inception.

Net Loss Per Common Share

Basic net loss per share of common stock is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the periods. Diluted net loss per common share is computed by giving effect to all potential shares of common stock, including restricted stock awards (“RSAs”), warrants, and stock options, to the extent dilutive. Stock options and warrants with exercise prices greater than the average market price of the Company’s common stock for the period are excluded from the calculation of diluted net loss per share as their inclusion would be anti-dilutive. For the years ended December 31, 2025 and 2024, due to a net loss, all potential shares of common stock were not included in the calculation of dilutive net loss per share as their effect would have been anti-dilutive. As a result, diluted net loss per common share is the same as basic net loss per common share for the periods presented.

The net loss per common share presented in the consolidated statements of operations is based on the following for the years ended December 31, 2025 and 2024:

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09 (Topic 740), Improvements to Income Tax Disclosures. The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as an expansion of other income tax disclosures. The ASU is effective on a prospective basis for annual reporting periods beginning after December 15, 2024. The Company adopted ASU 2023-09 in its fourth quarter of 2025 for the period ending December 31, 2025, and the adoption impacted only the disclosures with no material impact on the Company’s consolidated financial statements.

Issued in November 2024, ASU 2024-03, Disaggregation of income Statement Expenses (Subtopic 220-40), requires the disaggregated disclosure of specific expense categories, including purchases of inventory, employee compensation, depreciation, and amortization, within relevant income statement captions. This ASU also requires disclosure of the total amount of selling expenses along with the definition of selling expenses. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Adoption of this ASU can either be applied prospectively to consolidated financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the consolidated financial statements. While early adoption is permitted, the Company does not plan to adopt this standard early. This ASU will likely result in additional disclosures being included in the Company’s consolidated financial statements once adopted. The Company is currently evaluating the provisions of this ASU and the impact it will have on its consolidated financial statements.

Note 4 — Business Combination

Business Combination

On December 31, 2024, the Company consummated its Business Combination pursuant to the terms of the Business Combination Agreement. The Business Combination was structured as follows:

a)Prior to Closing, the sole outstanding Coliseum Class B Ordinary Share was converted into one Coliseum Class A Ordinary Share, which was then converted into one share of Holdco Class A Common Stock at Closing.
b)Prior to Closing, pursuant to Extension Non-Redemption Agreements and the Sponsor Support Agreement, the Previous Sponsor and Sponsor Affiliate forfeited and surrendered for no consideration an aggregate of 606,972 Coliseum Class A Ordinary Shares, and Coliseum issued 606,972 newly-issued Coliseum Class A Ordinary Shares to the Extension Non-Redeeming Shareholders.
c)On the Closing Date, each Coliseum Class A Ordinary Share issued and outstanding immediately prior to Closing (excluding redeemed public shares) was automatically converted into the right to receive one share of Holdco Class A Common Stock, and each whole Coliseum Public Warrant issued and outstanding immediately prior to Closing was assumed by Holdco and became exercisable for shares of Holdco Class A Common Stock.
d)On the Closing Date, each Private Placement Warrant was exchanged for 0.25 shares of Holdco Class A Common Stock in the Warrant Exchange.
e)On the Closing date, (i) each outstanding share of RET Preferred Stock and RET Class A Common Stock issued and outstanding immediately prior to Closing was converted into the right to receive a number of shares of Holdco Class A Common Stock equal to the Exchange Ratio and (ii) each share of RET Class B Common Stock issued and outstanding immediately prior to Closing was converted into the right to receive a number of shares of Holdco Class B Common Stock equal to the Exchange Ratio. The Exchange Ratio was approximately 1,434 shares of Holdco Common Stock for every outstanding share of RET Common Stock. Following the Closing, an aggregate of 1,232 shares of RET Preferred Stock and 250 shares of RET Class A Common Stock were converted into 2,125,539 shares of Holdco Class A Common Stock, and an aggregate of 40 shares of RET Class B Common Stock were converted into 57,752 shares of Holdco Class B Common Stock.
f)At Closing, each of the RET 1,500 Options outstanding was converted into 2,150,838 Holdco Option on the same terms and conditions as were in effect with respect to RET Option immediately prior to Closing, except that the exercise price per share of such Holdco Option is equal to the quotient of (x) the exercise price per share of such RET Option in effect immediately prior to Closing divided by (y) the Exchange Ratio (the exercise price per share, as so determined, being rounded up to the nearest full cent), which is equal to an exercise price of $2.06 per share.

PIPE Subscriptions Receivable

In connection with the Closing, Holdco entered into subscription agreements (collectively, the “PIPE Subscription Agreements”) with certain investors and related parties (the “PIPE Investors”) to sell an aggregate of 118,557 shares of Holdco Class A Common Stock at a purchase price of approximately $11.39 per share, for gross proceeds of $1.35 million. At the Closing, Holdco received $700,000 of the PIPE investment and issued an aggregate of 61,474 shares of Holdco Class A Common Stock to the PIPE Investors and recorded a subscription receivable of $650,000 for the remaining PIPE investment on the consolidated balance sheet as of December 31, 2024.

On January 29, 2025, the Company received $500,000 pursuant to the PIPE Subscription Agreements and issued 43,910 shares of Class A Common Stock. On February 6, 2025, the Company received the remaining $150,000 and issued 13,173 shares of Class A Common Stock. The subscription receivable was fully paid on February 6, 2025.

Forward Purchase Agreement with Meteora

On December 30, 2024, Holdco entered into a forward purchase agreement (the “Forward Purchase Agreement”) with Meteora Capital Partners, LP and affiliated funds (“Meteora”) for an OTC equity prepaid forward transaction. An aggregate of 361,858 shares of Holdco Class A Common Stock (the “Forward Purchase Shares”) are subject to the Forward Purchase Agreement, for which Meteora was paid approximately $4.1 million at Closing (the “Prepayment”) and the Company retained approximately $20,000 (the “Prepayment Shortfall”). The Forward Purchase Agreement matures on the date of the effectiveness of a certain registration statement filed by Holdco with the Securities and Exchange Commission following the Closing Date (the “Maturity Date”). Meteora may sell the Forward Purchase shares at any time following the Closing Date until the Maturity Date at a price not less than $10.00 per share. If Meteora sells any of the Forward Purchase Shares, Meteora will pay to Holdco $10.00 for each share sold, less the Prepayment Shortfall. On Maturity Date, any Forward Purchase Shares that have not been sold by Meteora will be returned to the Company for no consideration, provided that if the proceeds of the shares sold by Meteora prior to the Maturity Date is less than the Prepayment Shortfall, then Holdco will pay cash to Meteora in an amount equal to such difference.

The Company’s management determined that the prepaid Forward Purchase Agreement is a hybrid instrument with an embedded derivative (forward purchase contract), which meets the definition of a derivative and does not meet the criteria for the derivative accounting scope exception in ASC 815. As such, the embedded derivative is recognized initially and subsequently at fair value, with changes in fair value reported in earnings in accordance with ASC 815. Because the bifurcated embedded derivative is a forward contract, it must have an initial fair value of zero. As a result, the prepayment amount was allocated entirely to the host contract, which represents a receivable classified as contra-equity. Any shares issued under the Forward Purchase Agreement were accounted for and classified as issued and outstanding for accounting purposes.

Until the earlier of 1) the Maturity Date, and 2) the date that gross proceeds from the sale of the shares by Meteora equal 100% of the “Prepayment Shortfall”, the Company recognizes a liability for the Prepayment Shortfall at fair value, with subsequent changes in fair value recognized in the Company’s consolidated statements of operations each reporting period until the Maturity Date. As of December 31, 2024, the prepayment shortfall liability was recorded at maximum value.

Upon receipt of consideration related to the sale of any shares sold by Meteora, the Company will record the receipt of funds as an increase to cash and a decrease to the “Prepayment Shortfall liability” until the “Prepayment Shortfall Liability” is zero, and then any remaining proceeds received will reduce the receivable previously recorded as contra-equity.

The Company incurred no transaction costs that were directly related to issuance of the Forward Purchase Agreement.

As of December 31, 2024, the Company recorded the $4.1 million of Prepayment amount paid at closing within additional paid-in capital and approximately $20,000 in shortfall payment liability in the accompanying consolidated balance sheet.

As of December 31, 2025, the value of the shortfall payment liability of approximately $21,000 remained unchanged.

Public and Private Placement Warrants

Prior to Closing, Coliseum had 5,000,000 Public Warrants and 3,225,000 Private Placement Warrants outstanding. In connection with the Business Combination, as discussed above, an aggregate of 3,225,000 Private Placement Warrants were converted into 806,250 shares of Holdco Class A Common Stock, and the Public Warrants were exchanged into warrants to purchase 5,000,000 shares of Holdco Class A Common Stock.

Redemption

Prior to the Closing, certain Coliseum public shareholders exercised their right to redeem certain of their outstanding shares for cash, resulting in the redemption of 1,063,698 Coliseum public shares for an aggregate payment of approximately $12.1 million. After redemptions, there was a total of 723,414 Coliseum public shares and an aggregate of approximately $8.25 million remaining in Coliseum Trust Account, and was later converted into Holdco Class A Common Stock in connection with the Business Combination.

Consulting Agreement for Rainfall Ionization Equipment

The Company entered into a consulting agreement to engage its senior technology advisor, Scott Morris in 2022, pursuant to which the Company agreed to pay him a one-time fee upon execution of the agreement and a consulting fee of AUD 250,000 per year (equivalent to approximately $170,000 as of the effective date). In February 2025, the agreement was amended to increase the annual consulting fee to $186,000, and in June 2025, it was further increased to $252,000 in exchange for the consultant assuming an additional role and responsibilities. The agreement also provides for success fees payable upon the achievement of specified sales and development milestones. During the year ended December 31, 2025, the Company paid an aggregate of $50,000 in milestone payments to the Technical Advisor in connection with the achievement of certain development milestones.

In connection with the consulting agreement, the Company also obtained from Mr. Morris an irrevocable, perpetual, non-exclusive license under certain engineering designs in connection with rainfall ionization equipment and systems. The Company fully paid the license amount of $83,750 in June 2023.

Intangible assets as of December 31, 2025 and 2024 are composed of licenses under certain patents and designs for weather modification and rainfall ionization equipment to Dr. Anderson and Mr. Morris as discussed above.

The Company amortizes these intangible assets on a straight-line basis over the estimated useful lives of the assets under the full-month convention. The Company plans to continually adapt to incorporate new technologies and to expand into markets that may be created by new technologies for rainfall, snowfall enhancement and fog dispersion. As a result, the Company estimates a useful life often years for these intangible assets based on the Company’s expected period of technological relevance and use.

Intangible assets as of December 31, 2025 and 2024 were comprised of the following:

Note 7 — Related Party Transactions

On February 2, 2023, RET issued a promissory note (the “Note”) to its former CEO, Mr. You, and Mr. de Masi for $200,000 each, or an aggregate amount of $600,000. The Note has an annual interest rate of 5%. The Note amount owed to RET’s former CEO and Mr. de Masi totaling $400,000 remains as outstanding due on demand, and the $200,000 Note amount owed to Mr. You was included in the Rollover amount described below.

On December 30, 2024, Holdco entered into a loan agreement (the “Loan Agreement”) with RHY Management LLC (“RHY”), an affiliate of Harry You, Holdco’s Chairman, pursuant to which RHY agreed to issue a line of credit (the “LOC”) to Holdco for up to $7 million, in addition to the Rollover amount described below (such amounts borrowed under the LOC, together with the Rollover, the “Loan”). The Loan bears interest at the greater of 5% per annum or the applicable IRS short-term rate in the month of each drawdown (“Interest Rate”), payable quarterly in arrears. If a quarterly payment is missed, the loan balance increases by an amount equal to the principal multiplied by the Default Rate (as defined below). If an event of default has occurred and is continuing, then upon written notice by RHY to Holdco, the outstanding principal balance and any unpaid accrued interest will accrue interest at 2% above the Interest Rate (the “Default Rate”).

Prior to closing of the Business Combination, the outstanding amount that Coliseum and RET owed to Mr. You and his affiliates was approximately $3.1 million. All of these outstanding amounts (the “Rollover”) were assigned to and assumed by Holdco and are treated for all purposes as Loans outstanding under the Loan Agreement. The Rollover amount does not reduce the $7 million funding available to the Company under the LOC. As a result, as of December 31, 2024, the Company had approximately $3.1 million outstanding under the LOC, comprised solely of the Rollover amount.

As of December 31, 2025, the Company had drawn approximately $6.0 million under the LOC, in the combined form of cash proceeds and payments made on behalf of the Company, bringing the total outstanding balance under the Loan Agreement to approximately $9.1 million (including the $3.1 million Rollover).

As of December 31, 2025 and 2024, the Company had an outstanding accrued interest balance in connection with both the Note and the LOC of approximately $323,000 and $38,000, respectively.

Board of Directors Agreement

On April 1, 2025, the Board increased the size of the Board from five to seven directors and appointed Mr. Marcus Peperzak and Mr. Robert Reardon to the Board to fill the resulting vacancies. On December 22, 2025, the Board further increased its size from seven to eight directors and appointed Mr. David Sylvester as a Class II director.

In connection with their appointments to the Board, Mr. Reardon, Mr. Peperzak and Mr. Sylvester each entered into Director Agreements which are the form of agreement adopted by the Board in April 2025 to govern the terms of service and compensation of the Company’s non-employee directors (the “Director Agreements”). Additionally, effective as of April 4, 2025, the Company entered into Director Agreements with Lyman Dickerson, Alexandra Steele, and Christopher Riley, each non-employee members of the Board. Pursuant to the terms of the Director Agreements, the Company agreed to pay to each Board member (i) subject to approval by the Board and compensation committee of the Board (the “Compensation Committee”), a cash payment of $12,500 promptly following attendance at each quarterly Board meeting, for a total annual cash compensation of $50,000; and (ii) subject to approval by the Board and the Compensation Committee, a grant of restricted stock, with the number of shares and terms to be determined by the Board. The Company recognized an aggregate of $225,000 in connection with such agreements during the year ended December 31, 2025 within general and administrative expenses in the accompanying consolidated statements of operations. As of December 31, 2025, there has been no grants of restricted stock to the directors.

Note 8 — Warrants

As of December 31, 2025 and 2024, the Company has 5,000,000 warrants to purchase Holdco Class A Common Stock (“Warrants”) outstanding, which was the rollover of the 5,000,000 Coliseum Public Warrants upon closing of the Business Combination. The Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Warrants. The Warrants became exercisable on January 31, 2025 and will expire on December 31, 2029 at 5:00 p.m., New York City time, or earlier upon liquidation. Each Warrant entitles the holder thereof to purchaseone share of Class A Common Stock at an initial exercise price of $11.50 per share and exercisable on a cashless basis under certain circumstances specified in the warrant agreement.

The Warrants are being accounted for as derivative warrant liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The warrant liabilities are subject to re-measurement at each balance sheet date. With each such re-measurement, the warrant liabilities are adjusted to current fair value, with the change in fair value recognized in the Company’s statements of operations. The Company will reassess the classification at each balance sheet date. If the classification changes as a result of events during the period, the warrants will be reclassified as of the date of the event that causes the reclassification. Refer to Notes 3 and 9 for additional information on the fair value measurements of these warrants.

Note 9 — Fair Value Measurements

Financial liabilities measured at fair value during the periods on a recurring basis consisted of the following as of December 31, 2025 and 2024:

The Warrants are listed on the Nasdaq under the ticker “RAINW”. As of December 31, 2025 and 2024, the fair value measurements for the Warrants were classified as Level 2 due to low trading volume.

During the years ended December 31, 2025 and 2024, there were no transfers between levels of the fair value hierarchy.

Shares Authorization

The Company is authorized to issue 30,000,000 shares of Holdco Class A Common Stock, par value $0.0001,1,000,000 shares of Holdco Class B Common Stock, par value $0.0001, and 1,000,000 shares of preferred stock, par value $0.0001.

Holdco Class A Common Stock entitles the holders thereof toone vote per share on all matters on which the shares of Holdco Class A Common Stock is entitled to vote, and Holdco Class B Common Stock entitles the holders thereof tofifteen votes per share on all matters on which the shares of Holdco Class B Common Stock are entitled to vote.

The Holdco Class A Common Stock and the Holdco Class B Common Stock have identical economic rights, including dividend and liquidation rights.

Holdco Incentive Plan

Effective December 31, 2024, in connection with the Closing, the Company adopted the 2024 Equity Incentive Plan (the “2024 Incentive Plan”), which authorizes the grant of equity and equity-based incentive awards to officers, employees, non-employee directors and consultants.

Holdco initially reserved 747,168 shares of Class A Common Stock for the issuance of awards under the 2024 Incentive Plan. The number of shares reserved for issuance under the 2024 Incentive Plan will increase automatically on January 1 of each of 2025 through 2034 by the number of shares equal to 5.0% of the total number of outstanding shares (rounded down to the nearest whole share) of Class A Common Stock as of December 31 of the immediately preceding year. Notwithstanding anything to the contrary in the 2024 Incentive Plan, no more than the number of shares of Class A Common Stock initially reserved under the 2024 Incentive Plan may be issued pursuant to the exercise of incentive stock options (“ISOs”) under the 2024 Incentive Plan.

Shares of Class A Common Stock underlying awards that are forfeited, canceled, expire unexercised, or are settled in cash will again become available for issuance under the 2024 Incentive Plan. In the event of any change in Holdco’s capitalization, the plan’s Compensation Committee may, in its sole discretion, make equitable adjustments to (i) the number of shares reserved under the plan, (ii) the number of shares subject to outstanding awards, (iii) applicable award limits, and (iv) the exercise price of outstanding options.

The 2024 Incentive Plan has a term of 10 years from December 31, 2024, after which no additional awards may be granted. The Board may amend, suspend, or terminate the plan at any time, subject to stockholder approval to the extent required by law or the plan’s provisions.

On December 1, 2025, the number of shares reserved for issuance under the 2024 Incentive Plan was automatically increased by 5% pursuant to the terms of the 2024 Incentive Plan, resulting a total of 1,123,606 shares of Class A Common stock authorized for issuance.

As of December 31, 2025, the Company had issued 602,320 RSAs under the 2024 Incentive Plan to Mr. Seidl as described above, leaving 521,286 shares reserved and unissued under the plan.

Holdco Preferred Stock

As of December 31, 2025 and 2024, there wereno preferred shares outstanding, as retroactively restated to reflect the Business Combination.

Holdco Class A Common Stock

As of December 31, 2025 and 2024, the Company had an aggregate of 8,131,081 and 7,528,761 shares (including 602,320 and 0 restricted stock awards, respectively), of Class A Common Stock issued and outstanding, respectively.

Holdco Class B Common Stock

As of December 31, 2025 and 2024, the Company had an aggregate of 57,752 shares of Class B Common Stock issued and outstanding as a result of the conversion of shares in connection with the closing of the Business Combination as discussed in the Company’s Annual Report on Form 10-K filed with the SEC on April 16, 2025.

Stock Options

On August 23, 2024, the Company granted 1,433,892 and 716,946 options, as retroactively restated to reflect the Business Combination, to purchase RET’s Class A common stock to Harry You and Niccolo de Masi, respectively. The options expireten years from the date of grant, had an exercise price of $2.06 and were fully vested upon the grant date. As of December 31, 2025 and 2024, the Company had an aggregate of 2,150,838 options issued and outstanding.

The Company recognized approximately $2.8 million for stock-based compensation expenses upon issuance of such options in August 2024 within general and administrative expenses in the accompanying consolidated statements of operations during the year ended December 31, 2024. The fair value of the operations was measured on the date of grant using a hybrid method of probability weighted expected return (“PWERM”), where the equity value was allocated in one or more of the scenarios using a Black-Scholes option pricing model.

The assumptions used in the Company’s model represent management’s best estimates. These estimates are complex, involve a number of variables, uncertainties and assumptions and the application of management’s judgment, so that they are inherently subjective. If factors change and different assumptions are used, the stock-based compensation expense could be materially different in the future.

These assumptions are estimated as follows:

●Estimated value of common stock: The Company allocated equity value in one or more of the scenarios using a Black-Scholes option pricing model to derive the estimated value of common stock
●Risk-free interest rate: The Company used the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term of the options for each option group.
●Expected term: The expected term represents the period that the stock-based awards are expected to be outstanding. Because of the limitations on the sale or transfer or the Company’s common stock as a privately held company as of grant date, the Company does not believe its historical exercise pattern is indicative of the pattern it will experience as a publicly traded company. The Company estimated that the options issued to its holders of Founder Shares will be held for the full ten-year term.
●Volatility: The Company determined the price volatility factor based on the historical volatilities of selected peer group as the Company did not have a sufficient trading history for its common stock.
●Dividend yield: The expected dividend assumption is based on the Company’s current expectations about our anticipated dividend policy. The Company currently does not expect to issue any dividends.

The following assumptions were used in determining the fair value of the options granted during the year ended December 31, 2024:

Risk free interest rate4.17%
Expected term (in years)10
Expected volatility45.0%
Dividend yield0.0%
Estimated underlying stock price$2,897.12
Fair value of options (per share)$1,851.67

Restricted Stock Awards (RSAs)

RSAs are awards of common stock that are legally issued and outstanding. RSAs are subject to time-based restrictions on transfer and unvested portions are generally subject to a risk of forfeiture if the award recipient ceases providing services to the Company prior to the lapse of the restrictions or does not meet certain performance conditions.

The following summarizes the Company’s restricted stock award activity and the RSAs outstanding:

Granted602,3204.40
Forfeited--
Vested--
Unvested at December 31, 2025602,3204.400.50

The aggregate fair value was calculated based on the closing market price of the Company’s common stock on the date of grant and is recognized ratable over the vesting period. The Company recognized approximately $1.6 million of stock compensation expense within the general and administrative expenses in the accompanying consolidated statements of operations for the year ended December 31, 2025. As of December 31, 2025, total unrecognized compensation cost related to RSAs was approximately $1.0 million, which is expected to be recognized over a remaining weighted-average vesting period of 0.5 years.

Deferred tax asset, net of allowance$-$-

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax assets, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance as of December 31, 2025 and 2024.

The provision for income taxes differs from the amount of income tax determined by applying the applicable U.S. statutory federal income tax rate to income from continuing operations before income taxes as follows for the year ended December 31:

The Company’s income tax expense was related to taxes incurred in Massachusetts. The Company didnot pay any other income taxes, net of refunds, during the year ended December 31, 2025. There wereno unrecognized tax benefits or accruals for interest and penalties as of December 31, 2025 and 2024. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company has been subject to income tax examinations by major taxing authorities since inception. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Legislative and Regulatory Considerations

In 2025, the U.S. government enacted federal tax legislation that modifies certain provisions of the Internal Revenue Code, including changes to the limitation on the deductibility of business interest expense under Section 163(j), the capitalization and amortization of research and experimental expenditures under Section 174, bonus depreciation rules, and certain loss and credit utilization provisions.

The Company evaluated the impact of the legislation in accordance with ASC 740, Income Taxes. The effects of changes in tax law are recognized in the period of enactment. Based on the Company’s analysis, the enactment of this legislation did not result in a material change to the Company’s deferred tax assets or liabilities as of December 31, 2025 and did not materially impact the Company’s effective tax rate for the year then ended.

Note 12 — Segment Information

ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the Company’s chief operating decision maker, or group, in deciding how to allocate resources and assess performance.

The Company operates and manages the business asone reportable and operating segment, which is the business of developing, manufacturing and commercializing ionization AEI technology. The Company’s Chief Executive Officer has been identified as the chief operating decision maker (“CODM”), who reviews the operating results for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that the Company only hasone operating segment.

When evaluating the Company’s performance and making key decisions regarding resource allocation, the CODM reviews several key metrics, which include the following:

For the years ended December 31,
2025 · 2024
Installation costs$402,422$-
General and administrative and state tax expenses6,014,6284,491,931
Research and development expenses62,011-
Other significant non-cash items:
Stock based compensation expense1,634,864-
Depreciation expense6,901-
Amortization expense11,67511,675
Loss from operations(8,132,501)(4,503,606)
Total other income (expenses)(958,853)(30,155)
Net loss$(9,091,354)$(4,533,761)

As the Company has not earned any revenue, the key measures of segment profit or loss reviewed by the Company’s CODM are general and administrative expenses, installation and research and development expenses to monitor, manage and forecast cash to ensure enough capital is available for working capital needs. The CODM also reviews general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget.
