To the Shareholders and the Board of Directors of

Amaze Software, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Amaze Software, Inc. (the “Company”) as of December 31, 2023, and 2022, and the related consolidated statements of operations and comprehensive loss, stockholders' equity and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023, and 2022, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgements. We determined that there are no critical audit matters.

Notes to Consolidated Financial Statements

1. DESCRIPTION OF BUSINESS

Nature of Business

Amaze Software, Inc. (the “Company” or “Amaze”) is an innovative software company dedicated to empowering creators by providing comprehensive software solutions and services that facilitate e-commerce, social commerce, and integrated commerce selling experiences. Established in 2011 under the name Famous Industries, the company rebranded to Amaze in 2021 to better reflect its mission and broaden its focus on serving creators, entrepreneurs, and a diverse range of users seeking to build and enhance their online brands.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The Company's financial statements have been prepared and are presented in accordance with United States generally accepted accounting principles (“U.S. GAAP”). The financial statements include, in the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair presentation of the financial statements. In certain instances, amounts reported in prior period financial statements have been reclassified to conform to the current financial statement presentation.

Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles (“GAAP”) in the United States of America (“U.S.”) as promulgated by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). 

The accompanying consolidated financial statements include the accounts of Amaze Software, Inc. and Amaze Holding LLC, which are consolidated due to direct ownership.

Liquidity and Capital Resources 

As of December 31, 2023, the Company maintained $1 million in cash reserves with a working capital deficiency of $11 million. This reflects a strategic allocation of resources to support operational growth and investment in key business areas. In comparison, as of December 31, 2022, the Company had $9 million in cash and a working capital deficit of $4 million. The change was primarily driven by a targeted deployment of $7.6 million, ensuring the Company's continued ability to execute its long-term strategy and sustain its market position.

The Company believes that its existing cash, coupled with additional capital raised through debt financing, will provide adequate liquidity to support ongoing operations and growth initiatives for at least 12 months from the filing of this report. Management remains focused on capital efficiency and cash flow optimization, ensuring that financial resources are utilized effectively to drive operational performance and revenue expansion.

As of December 31, 2023, the Company had $12.4 million in current liabilities, reflecting its commitment to fulfilling short-term obligations while maintaining operational flexibility. The breakdown of these liabilities includes:

The Company reported an accumulated deficit of $81 million as of December 31, 2023, reflecting the investments made in product development, strategic initiatives, and market expansion. Management is actively exploring opportunities to strengthen the Company's capital structure by securing additional funding through strategic partnerships, equity financing, and revenue-driven growth. While there is an expectation for additional capital needs, the Company remains proactive in identifying favorable financing opportunities, ensuring alignment with its long-term objectives.

Management is confident in the Company's ability to navigate its financial landscape effectively, leveraging a combination of cost optimizations, revenue enhancements, and capital market strategies. Although external financing may be required to further accelerate growth, the Company is well-positioned to capitalize on favorable market conditions and strategic business opportunities.

While these factors present financial challenges, they also underscore the Company's ongoing commitment to strengthening its financial position and enhancing long-term sustainability. The accompanying financial statements do not include any adjustments related to the potential recoverability of assets, classification of liabilities, or other financial modifications that may be necessary under a different operating scenario. 

Accounting Estimates

Management uses estimates and assumptions in preparing these financial statements in accordance with U.S. GAAP. Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Actual results could differ from those estimates.

 Cash

The Company maintains its cash in accounts at financial institutions, which may, at times, exceed amounts insured by the Federal Deposit Insurance Corporation. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk.

Accounts Receivable

Accounts receivable consists of amounts owed to the Company for sales of the Company's services on credit and are reported at net realizable value. Credit terms are extended to customers in the normal course of business. The Company estimates allowances for future returns and doubtful accounts based upon historical experience and its evaluation of the current status of receivables. Accounts considered uncollectible are written off against the allowance. As of December 31, 2023 and 2022 there was no allowance for doubtful accounts.

Revenue recognition

The Company's total revenue reflects the sale of merchandise sales, digital product sales and shipping domestically and internationally. Revenues are recognized as the Company transfers control of promised goods or services to sellers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Each contract includes a single performance obligation to transfer control of the product to the customer. Control is transferred when the product is either shipped or delivered, depending on the shipping terms, at which point the Company recognizes the transaction price for the product as revenue. The Company has elected to account for shipping and handling as a fulfillment activity, with amounts billed to customers for shipping and handling included in total revenue.

ASC 606 notes that when another party is involved in providing goods or services to a customer, the entity should determine whether the nature of its promise is a performance obligation to provide the specified goods or services itself (that is, the entity is a principal) or to arrange for those goods or services to be provided by the other party (that is, the entity is an agent). The Company does not bear responsibility for inventory losses and does not have pricing determination; therefore, the Company would be considered the agent and revenue should be recognized as net sales.

Products are sold for cash or on credit terms. The Company has elected the practical expedient to not account for significant financing components as its payment terms are less than one year, and the Company determines the terms at contract inception. The Company's sales terms do not allow for the right of return.

The following table presents the percentages of total revenue disaggregated by sales channels for the years ended December 31, 2023 and 2022:

Fair Value of Financial Instruments

The Company's accounting for fair value measurements of assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring or nonrecurring basis adheres to the Financial Accounting Standards Board (FASB) fair value hierarchy that prioritizes the inputs to valuation techniques used to measure 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 measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

The level in the fair value hierarchy within which a fair measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety.

The carrying values of cash, accounts receivable, accounts payable, deferred revenue and other financial working capital items approximate fair value at December 31, 2024 and 2023, due to the short maturity nature of these items.

Fixed Assets

Fixed assets are stated at cost, less accumulated depreciation. Additions and improvements to property and equipment are capitalized at cost. Depreciation of owned assets are computed using the straight-line method over the estimated useful lives. The cost of assets sold or retired, and the related accumulated depreciation are removed from the accounts and any resulting gains or losses are reflected in other income (expense) for the year. Expenditures on maintenance and repairs are charged to expense as incurred.

Intangible Assets

The Company capitalizes the fair value of intangible assets acquired in business combinations. Intangible assets are amortized on a straight-line basis over their estimated economic useful lives, generally the contract term. The Company performs valuations of assets acquired and liabilities assumed on each acquisition accounted for as a business combination and allocates the purchase price of each acquired business to its respective net tangible and intangible assets.

Long-lived Assets

Long-lived assets such as fixed assets and intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. There were no triggering events and no impairments of long-lived assets for the years presented.

Customer Deposits

The Company records customer deposits when a customer makes a payment for a product purchase in advance of shipping goods. Revenue is recognized, and the customer deposit liability is reduced, once the shipment occurs and therefore this balance is related to customer orders that have not been fulfilled.

Accounts Payable

The Company records accounts payable at the invoice amount when goods or services are received, regardless of when payment is made. All vendor payables are recorded at their gross amount, with any discounts available being recognized as a separate income item when taken, and are typically due within 30 – 60 days.

Income Taxes

The Company recognizes uncertain tax positions in accordance with ASC 740 on the basis of evaluating whether it is more likely than not that the tax positions will be sustained upon examination by tax authorities. For those tax positions that meet the more-likely-than not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement. The Company recognizes interest and/or penalties related to uncertain tax positions in income tax expense. There were no uncertain tax positions as of December 31, 2023 and 2022, and as such, no interest or penalties were recorded to income tax expense. As of December 31, 2023 and 2022, the Company has no unrecognized tax benefits. There are no unrecognized tax benefits included on the balance sheet that would, if recognized, impact the effective tax rate. The Company does not anticipate there will be a significant change in unrecognized tax benefits within the next 12 months.

Equity-Based Compensation

The Company measures equity-based compensation cost, according to ASC 718, at the grant date based on the fair value of the award and recognizes the compensation expense over the requisite service period, which is generally the vesting period. The Company recognizes any forfeitures as they occur.

See Note 9 for further discussion of equity-based compensation incurred in 2024 and 2023.

Advertising and Marketing

The Company expenses the costs of advertising and marketing as incurred. Advertising and marketing expenses were approximately $3.1 million and $1.1 million for the years ended December 31, 2023 and 2022, respectively.

Recently Issued Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, and also issued subsequent amendments to the initial guidance, collectively, ASC 326, to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that requires the reflection of expected credit losses and will also require consideration of a broader range of reasonable and supportable information to determine credit loss estimates. For many entities with financial instruments, the standard will require the use of a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses, which may result in the earlier recognition of credit losses on financial instruments. The Company adopted this guidance during the quarter ended March 31, 2023, which had no material impact on the financial statements.

3. LOSS PER SHARE

Basic net loss per share is determined by dividing net loss attributable to common shareholders by the weighted-average shares outstanding during the period. Diluted EPS reflects potential dilution and is computed by dividing net loss by the weighted average number of common shares outstanding during the period increased by the numbers of additional common shares that would have been outstanding if all potential common shares had been issued and were dilutive. However, potentially dilutive securities are excluded from the computation of diluted EPS to the extent that their effect is anti-dilutive. The following table shows the components of diluted shares for the periods ending:

4. PREPAID EXPENSES

Prepaid expenses consist of the following at December 31:

5. FIXED ASSETS

6. INTANGIBLE ASSETS
