Notes to the Unaudited Condensed Consolidated Financial Statements

1. NATURE OF OPERATIONS

Serve Operating Co. (“Serve”) (formerly known as Serve Robotics Inc.) is a corporation formed on January 15, 2021 under the laws of the State of Delaware.

On July 31, 2023, Serve Acquisition Corp., a corporation formed in the State of Delaware on July 10, 2023 (“Acquisition Sub”) and wholly-owned subsidiary of Patricia Acquisition Corp., a Delaware corporation incorporated on November 9, 2020 (“Patricia”), merged with and into the Company (as defined below). Pursuant to this transaction (the “Merger”), Serve was the surviving corporation and became Patricia’s wholly owned subsidiary, and all of the outstanding stock of Serve was converted into shares of Patricia’s common stock. All of Serve’s outstanding warrants and options were assumed by Patricia. In addition, on July 31, 2023, the board of directors of Patricia and all of its pre-Merger stockholders approved a restated certificate of incorporation, which was effective upon its filing with the Secretary of State of the State of Delaware on July 31, 2023, and through which Patricia changed its name to “Serve Robotics Inc.” Following the consummation of the Merger, Serve Robotics Inc. changed its name to “Serve Operating Co.”

As a result of the Merger, Patricia acquired the business of Serve and continued the existing business operations of Serve as a public reporting company under the name Serve Robotics Inc. (the “Company”). The Company is developing autonomous robots for last-mile delivery services. The Company is headquartered in Redwood City, California. In accordance with “reverse merger” or “reverse acquisition” accounting treatment, the Company was determined the accounting acquirer. Patricia’s historical financial statements before the Merger have been replaced with the historical financial statements of Serve before the Merger in filings with the SEC since the Merger unless otherwise noted.

Public Offering

On April 17, 2024, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Aegis Capital Corp. (“Aegis”) in connection with the public offering of 10,000,000 shares of the Company’s common stock, par value $0.0001, at a public offering price of $4.00 per share (the “Offering”). The Company’s net proceeds from the Offering, after deducting the underwriting discount and other estimated offering expenses payable by the Company, were approximately $35.8 million. As a result of the Offering, the Company’s common stock was approved for listing on The Nasdaq Capital Market and commenced trading under the ticker symbol “SERV” beginning on April 18, 2024. See Note 7.

2. REVERSE MERGER ACCOUNTING

On July 31, 2023, Acquisition Sub, merged with and into the Company. Pursuant to the Merger, the Company was the surviving corporation and became Patricia’s wholly owned subsidiary, and all of the outstanding stock of Serve was converted into shares of Patricia’s common stock. All of Serve’s outstanding warrants and options were assumed by Patricia. Following the consummation of the Merger, Serve Robotics Inc. changed its name to “Serve Operating Co.”

The Merger was accounted for as a reverse-merger, and recapitalization in accordance with generally accepted accounting principles in the United States (“GAAP”). Serve Robotics Inc. was the acquirer for financial reporting purposes and Patricia was the acquired company. Consequently, the assets and liabilities and the operations that are reflected in the historical financial statements prior to the Merger are those of Serve Robotics Inc. and have been recorded at the historical cost basis of Serve Robotics Inc., and the financial statements after completion of the Merger include the assets and liabilities of Patricia and Serve Robotics Inc., historical operations of Serve Robotics Inc. and operations of Patricia from the closing date of the Merger. Common stock and the corresponding capital amounts of Patricia pre-merger were retroactively restated as capital stock shares reflecting the exchange ratio in the Merger. In conjunction with the Merger, the Company received no cash and assumed no liabilities from Patricia.

As a result of the Merger, each of Serve’s shares of capital stock issued and outstanding immediately prior to the closing of the Merger was converted into the right to receive 0.8035 shares of Patricia’s common stock (the “Common Share Conversion Ratio”). Accordingly, all share and per share amounts for all periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect the Common Share Conversion Ratio. There was no effect on the number of shares of common stock or preferred stock authorized for issuance under the Company’s certificate of incorporation or the par value of such securities.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accounting and reporting policies of the Company conform to GAAP. The Company’s fiscal year end is December 31.

Reclassifications

Certain amounts in prior periods have been reclassified to conform to the current period presentation.

Principles of Consolidation

These consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Serve Operating Co. and Serve Robotics Canada Inc. All inter-company transactions and balances have been eliminated on consolidation.

Unaudited Condensed Consolidated Financial Information

The unaudited condensed consolidated financial statements and related notes have been prepared in accordance with GAAP for interim financial information, within the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements have been prepared on a basis consistent with the audited financial statements and in the opinion of management, reflect all adjustments, consisting of only normal recurring adjustments, necessary for the fair presentation of the results for the interim periods presented and of the financial condition as of the date of the condensed consolidated balance sheet. The financial data and the other information disclosed in these notes to the condensed consolidated financial statements related to the three-month periods are unaudited. Unaudited interim results are not necessarily indicative of the results for the full fiscal year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto for the year ended December 31, 2023 included in the Form 10-K filed with the SEC on February 29, 2024.

Liquidity and Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern within one year after the date that the financial statements are issued and contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainty described below.

Management’s plans discussed below have alleviated the substantial doubt outlined below regarding the Company’s ability to continue as a going concern for the one-year period from the date that these financial statements were issued.

As of September 30, 2024, the Company had $50.91 million in cash and cash equivalents and had a working capital deficiency. During the three and nine months ended September 30, 2024, the Company incurred a net loss of $8.00 million and $26.07 million, respectively. During the nine months ended September 30, 2024, the Company had net cash flows used in operating activities of $15.28 million.

In accordance with Accounting Standards Codification (“ASC”) Topic 205-40, Presentation of Financial Statements - Going Concern, the Company evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. While the Company’s current cash flow forecast for the one-year going concern look forward period estimates that there will be sufficient capital available to fund operations, this forecast is subject to significant uncertainty, including as it relates to revenue for the next twelve months. The Company’s revenue projections depend on its ability to successfully design, develop and operate low-emissions robots that serve people in public spaces, which is inherently uncertain and subject to a number of risks.

Management believes that, given the history of recurring losses, negative working capital, expected future capital expenditures, and accumulated deficit, conditions or events exist that raise substantial doubt about the Company’s ability to continue as a going concern through one year from the date that these financial statements are issued. Management’s plans to alleviate such conditions or events may include pursuing equity financing, debt funding, and alternative funding sources. Management’s plans include execution of its commercial plans, primarily related to capital expenditures around its robot fleet. The Company has a successful history of accessing equity markets.

New financings may not be available to the Company on commercially acceptable terms, or at all. Also, any additional collaborations, strategic alliances, asset sales and marketing, distribution, or licensing arrangements may require the Company to give up some or all of its rights to a product or technology, which in some cases may be at less than the full potential value of such rights. If the Company is unable to obtain additional capital, the Company will assess its capital resources and may be required to delay, reduce the scope of, or eliminate some or all of its operations, including capital expenditures, or downsize its organization, any of which may have a material adverse effect on its business, financial condition, results of operations, and ability to operate as a going concern. In addition, geopolitical tensions, volatility of capital markets, and other adverse macroeconomic events, including those due to inflationary pressures, rising interest rates, banking instability, monetary policy changes and the ability of the U.S. government to manage federal debt limits as well as the potential impact of other health crises on the global financial markets may reduce the Company’s ability to access capital, which could negatively affect its liquidity and ability to continue as a going concern.

Use of Estimates

The preparation of the Company’s financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, the valuations of common stock and options. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates when there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company generally maintains balances in various operating accounts at financial institutions that management believes to be credit worthy, in amounts that may exceed federally insured limits. The Company has not experienced any losses related to its cash and cash equivalents and does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

Concentrations

During the nine months ended September 30, 2024, one customer accounted for 72% of the Company’s revenue and accounted for 88% of the Company’s accounts receivable. In the same period in 2023, a different customer accounted for 68% of the Company’s revenue.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents.

Fair Value Measurements

Certain assets and liabilities of the Company 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 (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. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

The carrying values of the Company’s accounts receivable, prepaid expenses and accounts payable and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities.

See Note 4 for fair value disclosures.

Accounts Receivable

Accounts receivable are derived from services delivered to customers and are stated at their net realizable value. The Company accounts for allowance for doubtful accounts under ASC 310-10-35. Each month, the Company reviews its receivables on a customer-by-customer basis and evaluates whether an allowance for doubtful accounts is necessary based on any known or perceived collection issues. Any balances that are eventually deemed uncollectible are written off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. As of September 30, 2024 and December 31, 2023, the Company determined there was no allowance for doubtful accounts necessary.

Inventory

Inventory is stated at the lower of cost or market value and accounted for using the specific identification cost method. As of September 30, 2024 and December 31, 2023, inventory primarily consists of robotic component parts purchased from the Company’s suppliers. Management reviews its inventory for obsolescence and impairment periodically and did not record a reserve for obsolete inventory for the nine months ended September 30, 2024 and 2023.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation expense is recognized using the straight-line method over the estimated useful life of the asset, which is three (3) to five (5) years for office equipment and two (2) years for the Company’s robot assets. Estimated useful lives are periodically assessed to determine if changes are appropriate. Maintenance and repairs are charged to expense as incurred. When assets are retired or otherwise disposed of, the cost of these assets and related accumulated depreciation or amortization are eliminated from the balance sheets and any resulting gains or losses are included in the statement of operations in the period of disposal.

Impairment of Long-Lived Assets

The Company continually monitors events and changes in circumstances that could indicate carrying amounts of long-lived assets may not be recoverable. When such events or changes in circumstances are present, the Company assesses the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the future cash flows is less than the carrying amount of those assets, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or the fair value less costs to sell.

Deferred Offering Costs

The Company complies with the requirements of ASC 340-10-S99-1 with regards to offering costs. Prior to the completion of an offering, offering costs are capitalized. The deferred offering costs are charged to additional paid-in capital or as a discount to debt, as applicable, upon the completion of an offering or to expense if the offering is not completed. As of September 30, 2024, the Company did not have any capitalized deferred offering costs.

Convertible Instruments

GAAP requires companies to bifurcate conversion options from their host instruments and account for them as free-standing derivative financial instruments according to certain criteria. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument. An exception to this rule is when the host instrument is deemed to be conventional as that term is described under applicable GAAP.

Revenue Recognition

The Company accounts for revenue in accordance with ASC 606 – Revenue from Contracts with Customers (“ASC 606”). The Company determines revenue recognition through the following steps:

Revenue is recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. As a practical expedient, the Company does not adjust the transaction price for the effects of a significant financing component if, at contract inception, the period between customer payment and the transfer of goods or services is expected to be one year or less.

The Company recognizes revenue on its software services over time. The Company utilizes labor hours as a measure of progress to estimate the percentage of completion of the performance obligation at each reporting period. Service fees that have been invoiced or paid but performance obligations have not been met are recorded as deferred revenue. As of September 30, 2024, the Company had $14,097 in deferred revenue pertaining to software services.

For delivery services, the Company satisfies its performance obligation when the delivery is complete, which is the point in time control of the delivered product transfers to the customer.

The Company recognizes branding fees over time as performance obligations are completed over the term of the agreement.

Disaggregation of Revenue

The disaggregation of revenue is as follows:

Cost of Revenue

Cost of revenue consists primarily of allocations of depreciation on robot assets used for revenue producing activities, personnel time related to revenue activities, and costs related to data, software and similar costs that allow the robots to function as intended and for the Company to communicate with the robots while in service.
