Organization Consolidation And Presentation Of Financial Statements [Abstract]

Description of Business

1. Description of Business

We are a global provider of advanced solar tracker systems, supported by proprietary software and value-added engineering services. Our mission is to provide differentiated products, software and services that maximize energy generation and cost savings for our customers, and to help facilitate the continued growth and adoption of solar power globally. Trackers significantly increase the amount of solar energy produced at a solar installation by moving solar panels throughout the day to maintain an optimal orientation relative to the sun. Our tracker systems are currently marketed under the Voyager brand name (“Voyager Tracker” or “Voyager”). Voyager is a next-generation two-panel in-portrait single-axis tracker solution that we believe offers industry-leading performance and ease of installation. FTC Solar, Inc. (the “Company”, “we”, “our”, or “us”) was founded in 2017 and is incorporated in the state of Delaware. The Company is a team of dedicated renewable energy professionals focused on delivering cost reductions to our clients across the solar project development and construction cycle. With significant US and worldwide project installation experience, our differentiated offerings drive value for solar solutions spanning a range of applications including ground mount, tracker, canopy, and rooftop. The Company is headquartered in Austin, Texas and has subsidiaries in Australia, India, Singapore, and South Africa.

Initial Public Offering and Related Transaction

The Company’s common stock began trading on the Nasdaq Stock Exchange on April 28, 2021, under the symbol “FTCI” and on April 30, 2021, the Company completed its Initial Public Offering (“IPO”). In connection with the IPO, the Company issued and sold 19,840,000 shares of its common stock at a public offering price of $13.00 per share.

Prior to the completion of the IPO, the Board of Directors and Stockholders approved an approximately 8.25-for-1 forward stock split (the “Forward Stock Split”) of the Company’s shares of common stock which became effective on April 28, 2021.

The Company received aggregate proceeds of $241.2 million from the IPO, net of the underwriting discount and commissions and before offering costs and used $54.2 million to purchase and retire an aggregate of 4,455,384 shares of our common stock, some of which resulted from the settlement of certain vested RSUs and the exercise of certain options in connection with the IPO at the IPO price less underwriting discounts and commissions.

Offering costs, including legal, accounting, printing and other IPO-related costs, have been reclassified to Additional paid-in capital and recorded against the proceeds from the offering during the quarter ended June 30, 2021.

JOBS Act Accounting Election

We are an emerging growth company, as defined in the Jumpstart Our Business Startups (JOBS) Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. Accordingly, we will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies or that have opted out of using such extended transition period.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

These unaudited condensed consolidated financial statements include the results of the Company and its wholly owned subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). Intercompany accounts and transactions have been eliminated upon consolidation.

Forward Stock Split

On April 28, 2021, we effected an approximately 8.25-for-1 forward split of our issued and outstanding shares of common stock, par value $0.0001 per share. As a result of the Forward Stock Split, one (1) share of common stock issued and outstanding was automatically increased to approximately 8.25 shares of issued and outstanding common stock, without any change in the par value per share. All information related to common stock, stock options, restricted stock awards and earnings per share have been retroactively adjusted to give effect to the Forward Stock Split for all periods presented.

Use of Estimates

The preparation of the Company’s financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities, expenses, and the disclosure of contingent assets and liabilities in the Company’s financial statements and accompanying notes. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis.

COVID-19 Pandemic

In March 2020, the World Health Organization declared the novel coronavirus 2019 (“COVID-19”) a global pandemic. The COVID-19 pandemic has had and may continue to have an unfavorable impact on certain parts of our business. The broader implications of the COVID-19 pandemic on our business, financial condition and results of operations remain uncertain and will depend on certain developments, including the duration and severity of the COVID-19 pandemic, the impact of virus variants, the rate of vaccinations, the COVID-19 pandemic’s impact on our customers and suppliers and the range of governmental and community reactions to the pandemic. We may continue to experience reduced customer demand in certain parts of our business or constrained supply that could materially and adversely impact our business, financial condition, results of operations, liquidity and cash flows in future periods.

Unaudited Interim Financial Information

The accompanying unaudited condensed consolidated financial statements as of June 30, 2021 and for the three and six months ended June 30, 2020 and 2021, have been prepared in accordance with GAAP for interim financial statements and pursuant to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments have been made that are considered necessary for a fair statement of our financial position as of December 31, 2020 and June 30, 2021, our results of operations for the three and six months ended June 30, 2020 and 2021 and our cash flows for the six months ended June 30, 2020 and 2021. The condensed consolidated balance sheets as of December 31, 2020 have been derived from the Company’s audited consolidated financial statements. Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.

Certain information and disclosures normally included in the notes to annual financial statements prepared in accordance with GAAP have been omitted from these interim financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s final prospectus (the “IPO Prospectus”) dated as of April 29, 2021, and filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended (the “Securities Act”).

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to concentration of credit risk, consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company is exposed to credit risk in the event of default by the financial institutions holding our cash and cash equivalents that are recorded on our

balance sheets. The Company mitigates its risk by investing in high-grade instruments and limiting the concentration in any one issuer, which limits its exposure. The Company has not experienced any losses since inception.

The carrying amounts of cash and cash equivalents, prepaid expenses, accounts payable and accrued other

liabilities are reasonable estimates of their fair value because of the short maturity of these items.

Equity Method Investments

The Company uses the equity method of accounting for equity investments if the investment provides the ability to exercise significant influence, but not control, over operating and financial policies of the investee. The Company’s proportionate share of the net income or loss of these investees is included in our Condensed Consolidated Statements of Comprehensive Loss. Judgment regarding the level of influence over each equity method investment includes considering key factors such as the Company’s ownership interest, legal form of the investee, representation on the board of directors, participation in policy-making decisions and material intra-entity transactions.

The Company evaluates equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by the Company when reviewing an equity method investment for impairment include the length of time and the extent to which the fair value of the equity method investment has been less than cost, the investee’s financial condition and near-term prospects and the intent and ability to hold the investment for a period of time sufficient to allow for anticipated recovery. An impairment that is other-than temporary is recognized in the period identified.

The Company accounts for distributions received from equity method investees under the “nature of the distribution” approach. Under this approach, distributions received from equity method investees are classified on the basis of the nature of the activity or activities of the investee that generated the distribution as either a return on investment (classified as cash inflows from operating activities) or a return of investment (classified as cash inflows from investing activities).

The Company has made an accounting policy election, as a result of disposing of its equity method investment on June 24, 2021, to account for the contingent gains from the earnout provision and projects escrow release only when those amounts become realizable in the periods subsequent to the disposal date. (See Note. 6)

Stock Based Compensation

The Company recognizes compensation expense for all share-based payment awards made, including stock options and restricted stock, based on the estimated fair value of the award on the grant date, in the accompanying consolidated statements of operations over the requisite service period of the awards. The Company calculates the fair value of stock options using the Black-Scholes Option-Pricing model. The fair value of restricted stock grants represents the estimated fair value of the Company's common stock on the date of grant. The Company accounts for forfeitures as they occur. For service-based awards, stock-based compensation is recognized using the straight-line attribution approach over the requisite service period. For performance-based awards, stock-based compensation is recognized based on graded vesting over the requisite service period when the performance condition is probable of being achieved.

Revenue Recognition

The Company derives its revenue primarily from sale of: (1) Voyager Tracker and customized components of Voyager Tracker, (2) individual parts of Voyager Tracker for certain specific transactions, (3) shipping and handling services, (4) term-based software licenses, (5) maintenance and support services for the term-based software licenses, and (6) subscription services. Product revenue includes revenue from Voyager Tracker and customized components of Voyager Tracker, individual part sales for certain specific transactions, and sale of term-based software licenses. Service revenue includes revenue from shipping and handling services, subscription-based enterprise licensing model, and maintenance and support services in connection with the term-based software licenses.

Voyager Tracker and individual parts of Voyager Tracker (including shipping and handling)

The Company contracts with customers for sale of Voyager Trackers under two different types of arrangements: (1) Purchase Agreements and Equipment Supply Contracts (“Purchase Agreements”) and (2) sale of individual parts of the Voyager Tracker.

The Company’s Purchase Agreements typically include two performance obligations- (1) Voyager Tracker or customized components of Voyager Tracker and (2) shipping and handling services. The deliverables included as part of the Voyager Tracker are predominantly accounted for as one performance obligation, as these deliverables are part of a combined promise to deliver a project. Voyager Tracker and customized components of Voyager Tracker performance obligations in the contract are satisfied over-time as work progresses for its custom assembled Voyager Tracker, utilizing an input measure of progress determined by cost-to-cost measures on these projects as this faithfully depicts the Company’s performance in transferring control.

The revenue for shipping and handling services is recognized over-time based on shipping terms of the arrangements, as this faithfully depicts the Company’s performance in transferring control.

The Company’s sale of individual parts of Voyager Tracker for certain specific transactions include multiple performance obligations consisting of individual parts of the Voyager Tracker. Revenue recognized for the Company’s part sales are recorded at a point in time and recognized when obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is in line with shipping terms.

Term-based software license revenue

Term-based software license revenue included under product revenue is primarily derived from sale of term-based software licenses that are deployed on the customers’ own servers and have significant standalone functionality. The revenue is recognized upon transfer of control to the customer. The control for term-based software licenses is transferred at the later of delivery to the customer or the software license start date. Term-based software license revenue is immaterial for the three and six month periods ended June 30, 2020 and June 30, 2021.

Subscription and Maintenance and support services revenue

Subscription revenue is derived from a subscription-based enterprise licensing model with contract terms typically ranging from one to two years and consists of subscription fees from the licensing of Subscription services. Subscription services revenue is immaterial for the three and six month periods ended June 30, 2020 and June 30, 2021. The hosted on-demand service arrangements do not provide customers with the right to take possession of the software supporting the hosted services. Services revenue includes maintenance and support service revenue related to term-based software licenses. Support revenue is derived from ongoing security updates, upgrades, bug fixes, and maintenance. A time-elapsed method is used to measure progress because the Company transfers control evenly over the contractual period. Accordingly, the fixed consideration related to these revenues is generally recognized on a straight-line basis over the contract term beginning on the date access is provided.

Cost of Revenue

Cost of revenue consists primarily of costs related to raw materials, freight and delivery, product warranty, and personnel costs (salaries, bonuses, benefits, and stock-based compensation). Personnel costs in cost of revenue include both direct labor costs as well as costs attributable to any individuals whose activities relate to the procurement, installment and delivery of the finished product and services. Deferred cost of revenue results from the timing differences between the costs incurred in advance of the satisfaction of all revenue recognition criteria consistent with our revenue recognition policy.

Warranty

We provide standard assurance type warranties with our Voyager Trackers for periods generally ranging from five to ten years. We record a provision for estimated warranty expenses, net of amounts recoverable from manufacturers, to cost of sales when we recognize

revenue. These estimates are based on our historical experience and forward-looking factors including the expected nature and frequency of product failure rates and costs to address future claims. These estimates are inherently uncertain given our relatively short history of sales and changes to our historical or projected warranty experience may result in material changes to our warranty reserve in the future. We do not maintain general or unspecified reserves; all warranty reserves are related to specific projects. All actual or estimated material costs incurred in subsequent periods are charged to those established reserves.

Remaining Performance Obligations

Remaining performance obligations relate to contracts that have original expected durations of one year or less. Therefore, the transaction price allocated to performance obligations that are unsatisfied or partially satisfied as of the end of the reporting period are not required to be disclosed under ASC 606.

Recent Accounting Pronouncements

Recently Adopted Accounting Standards

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 removes certain exceptions related to the approach for intra period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of GAAP. The Company adopted ASU 2019-12 in the first quarter of 2021, and the adoption had no material impact to the Company's consolidated financial statements.

New Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 changes the impairment model for most financial assets and requires the use of an expected loss model in place of the currently used incurred loss method. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The Company is currently evaluating the impact that the adoption of ASU 2016-13 will have on its condensed consolidated financial statements and the Company plans to adopt in beginning of year 2023.

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This standard provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The Company is currently evaluating the impact this adoption will have on the Company’s condensed consolidated financial statements and the Company plans to adopt in year 2022.

On June 24, 2021, the Company disposed of its 4,791,566 Class A common unit interest in Dimension Energy LLC, (“Dimension”) representing approximately 23% of the total outstanding common shares, for approximately $22.0 million, net of a success-based fee of $1.9 million. For the six months period ended June 30, 2021, the Company recognized a gain of $20.6 million due to its disposal of approximately 23% non-controlling interest in Dimension. The Company recognized net loss from the unconsolidated subsidiary of $0.2 million and $0.4 million for the six months ended June 30, 2020 and 2021, respectively.

Below is the summarized financial information of the investee through June 24, 2021, the date the Company disposed its entire interest in the investee, and the calculated share of loss from equity investment that is reported in net loss from unconsolidated subsidiary on the accompanying unaudited condensed consolidated statements of comprehensive loss for the six months ended June 30, 2020 and 2021(in thousands):

Share of net loss from equity method investment		(159	)		(354	)

The sales agreement with Dimension includes an earnout provision which provides the potential to receive an additional contingent consideration of up to approximately $14.0 million through December 2024, based on Dimension achieving certain performance milestones. This potential earnout is calculated each quarter starting January 1, 2022. The potential payment is calculated as $200 per the number of kilowatts constituting each Notice To Proceed (NTP) megawatt (MW) achieved during such quarterly earnout period, provided that no earnout amount is payable in respect to the first 100 NTP MW achieved in any earnout year. The sales agreement also includes a projects escrow release which is an additional contingent consideration to receive $7 million based on Dimension’s completion of certain construction projects currently in progress. The Company has made an accounting policy election to account for the contingent gains from the earnout provision and projects escrow release only when those amounts become realizable in the periods subsequent to the disposal date.

On June 29, 2021, the Company made a success-based fee payment in the amount of $1.9 million to two Executive Members of Dimension for entering into voting and support letter agreements and for recommending to all Executive Members of Dimension to support the purchase agreement and the consummation of the transaction on June 24, 2021.

Debt Disclosure [Abstract]

Debt and Other Borrowings

. Debt and Other Borrowings

On January 30, 2017, the Company sold $7.0 million in aggregate principal amount of secured five-year promissory notes (“the notes”) through a private placement. Pursuant to the issuance of the notes, the Company issued 25,000 shares of common stock for every $250,000 of notes purchased. The fair value of common stock issued was accounted for as debt discount and was amortized over the term of the notes. The notes had a fixed rate of 5% per annum payable at maturity. The Company repaid the principal during the year ended December 31, 2020.

On June 17, 2019, the Company entered into a revolving line of credit agreement with the Western Alliance Bank for a total principal amount of $1.0 million and maturity in two years from the date of borrowing. The line of credit had a variable rate of interest, based on movement of prime rate as calculated and published by the Wall Street Journal and required the Company to pay regular monthly payments of all interest accrued as of each payment date. The prime rate at the time of borrowing was at 5.50% per annum. The outstanding balance for the revolving line of credit as of December 31, 2020 was $1 million and as of March 31, 2021, the outstanding balance was paid in full and the revolving credit line was closed.

On April 30, 2020, the Company received a Paycheck Protection Program (“PPP”) loan pursuant to the Coronavirus Aid, Relief, and Economic Security Act (the “CARES” Act) in the amount of $0.8 million. The loan had a two-year term and bore a fixed interest rate of 1%. Under the terms of the CARES act, the loan was eligible to be forgiven, in part or whole, if the proceeds were used to retain and pay employees and for other qualifying expenditures. On January 20, 2021, the Company received notification from the Small Business Administration ("SBA") that they approved the forgiveness of the full $0.8 million PPP loan. The Company recorded the forgiveness of the PPP loan as a gain on debt extinguishment in other income.

On April 30, 2021, the Company entered into a $100 million senior secured revolving credit facility, by and among the Company, as borrower, the several financial institutions from time to time parties thereto, and Barclays Bank PLC, as an issuing lender, the swingline lender and as administrative agent (the “Credit Agreement”). The Credit Agreement has an initial three-year term, and it will be used for working capital and for other general corporate purposes. The Company has not made any draws on the revolving credit facility. The Credit Agreement includes the following terms: (i) aggregate commitments of up to $100 million, with letter of credit and swingline sub-limits; (ii) customary base rate of LIBOR plus 3.25% per annum, respectively; (iii) initial commitment fees of 0.50% per annum; (iv) initial letter of credit fees of 3.25% per annum; and (v) other customary terms for a corporate revolving credit facility.

The facility is secured by a first priority lien on substantially all of the Company’s assets, subject to certain exclusions, and customary guarantees. The Credit Agreement includes the following financial condition covenants that the Company is required to satisfy: (i) maintain a liquidity ratio with a minimum limit of $125 million for each quarter (ii) maintain a 3.75 times leverage ratio and (iii) maintain a 1.5 times interest coverage ratio. Once the leverage and interest coverage ratios are triggered the liquidity ratio will not have a minimum limit. The liquidity ratio covenant was the only financial condition covenant the Company had to satisfy as of the period ended June 30, 2021. As of June 30, 2021, the Company was in full compliance with its financial condition covenant.

The Company added $2.1 million in debt issuance costs related to the revolving credit facility which was included in other assets in the Condensed Consolidated Balance Sheets. The debt issuance costs are being amortized over a three year initial term of the loan. As of June 30, 2021 the unamortized debt issuance cost amounted to $2.0 million.

The Company recognized $0.1 million and $0.2 million of interest expense on its debt and other borrowings for the three months ended June 30, 2020 and 2021 and $0.2 million and $0.2 million for the six months ended June 30, 2020 and 2021, respectively.

. Commitments and Contingencies

Litigation

The Company may be involved in various claims, lawsuits, investigations, and other proceedings, arising from normal course of its business. The Company accrues a liability when management believes information available prior to the issuance of financial statements indicates it is probable a loss has been incurred as of the date of the financial statements and the amount of loss can be reasonably estimated. The Company adjusts its accruals to reflect the impact of negotiation, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Legal costs are expensed as incurred.

On April 21, 2021, FCX Solar, LLC (“FCX”), filed a lawsuit against us in the United States District Court for the Southern District of New York. The complaint alleges breach of contract and tort claims related to a patent license agreement and consulting relationship between FCX and us. FCX seeks damages of approximately $134 million in the lawsuit. On July 2, 2021, we filed a motion to dismiss the tort claims. On July 16, 2021, rather than responding to that motion, FCX filed an amended complaint asserting the same claims as the original complaint. On July 22, 2021, we advised the court that FTC would stand on its motion to dismiss, and at the request of the court, we filed a revised motion citing the amended complaint. FCX's response to the motion is due on August 13, 2021. On May 29, 2021, FCX filed a separate lawsuit against us in the United States District Court for the Western District of Texas, alleging a claim for patent infringement related to U.S. Patent No. 10,903,782. FCX seeks an unspecified amount of damages, including past and future royalties, and injunctive relief. Our answer to that complaint was filed on June 22, 2021, along with our motion to transfer the patent suit to the Southern District of New York to be consolidated with the New York litigation. FCX filed an amended complaint asserting claims for direct patent infringement, indirect infringement by active inducement, and contributory infringement on July 27, 2021, and we filed our answer to that complaint on August 10, 2021. The Company believes the claims asserted in both lawsuits are without merit, and we plan to vigorously defend against them. The Company and its management considered (a) the facts described above, (b) the preliminary stages of the proceedings and (c) the advice of outside legal counsel on the claims and determined that it is not probable that FCX will prevail on the merits. At this time the Company believes that the likelihood of any material loss related to these matters is remote given the strength of the Company’s defenses.

The Company has not recorded any material loss contingency in the Condensed Consolidated Balance Sheets as of December 31, 2020 and June 30, 2021.

Warranties

The Company provides standard warranties on its hardware products. The liability amount is based on actual historical warranty spending activity by type of product, customer, and geographic region, modified for any known differences such as the impact of reliability improvements. As of June 30, 2021, warranty reserves totaling $1.7 million were recorded in accrued expenses and other current liabilities and $3.8 million were recorded in other non-current liabilities, in the Company’s Condensed Consolidated Balance Sheets.

Changes in the Company’s product warranty reserves were as follows (in thousands):

We utilized a graded vesting method which results in an accelerated recognition of compensation costs. Stock-based compensation expense incurred was $0.5 million and $56.2 million for the three months ended June 30, 2020 and 2021 and $0.9 million and $56.6 million for the six months ended June 30, 2020 and 2021, respectively.

Income Tax Disclosure [Abstract]

Income Taxes

12. Income Taxes

For the three months ended June 30, 2020 and 2021, the Company recorded an income tax expense of $0.02 million and $0.12 million respectively. For the six months ended June 30, 2020 and 2021, the Company recorded an income tax benefit of $0.14 million and income tax expense of $0.1 million, respectively. Income tax expense recorded for three and six months ended June 30, 2020 and 2021, was lower than the statutory tax rate of 21% primarily due to a valuation allowance established against the U.S. deferred tax assets.

As of June 30, 2021, the Company had total unrecognized tax benefits of approximately $0.1 million. All of our gross unrecognized tax benefits, if recognized, would affect our effective tax rate. We recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. As of June 30, 2021, the Company had not accrued any interest or penalties related to unrecognized tax benefits.

Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Jun. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation These unaudited condensed consolidated financial statements include the results of the Company and its wholly owned subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). Intercompany accounts and transactions have been eliminated upon consolidation.
Forward Stock Split	Forward Stock Split On April 28, 2021, we effected an approximately 8.25-for-1 forward split of our issued and outstanding shares of common stock, par value $0.0001 per share. As a result of the Forward Stock Split, one (1) share of common stock issued and outstanding was automatically increased to approximately 8.25 shares of issued and outstanding common stock, without any change in the par value per share. All information related to common stock, stock options, restricted stock awards and earnings per share have been retroactively adjusted to give effect to the Forward Stock Split for all periods presented.
Use of Estimates	Use of Estimates The preparation of the Company’s financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities, expenses, and the disclosure of contingent assets and liabilities in the Company’s financial statements and accompanying notes. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis.
Covid-19 Pandemic	COVID-19 Pandemic In March 2020, the World Health Organization declared the novel coronavirus 2019 (“COVID-19”) a global pandemic. The COVID-19 pandemic has had and may continue to have an unfavorable impact on certain parts of our business. The broader implications of the COVID-19 pandemic on our business, financial condition and results of operations remain uncertain and will depend on certain developments, including the duration and severity of the COVID-19 pandemic, the impact of virus variants, the rate of vaccinations, the COVID-19 pandemic’s impact on our customers and suppliers and the range of governmental and community reactions to the pandemic. We may continue to experience reduced customer demand in certain parts of our business or constrained supply that could materially and adversely impact our business, financial condition, results of operations, liquidity and cash flows in future periods.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The accompanying unaudited condensed consolidated financial statements as of June 30, 2021 and for the three and six months ended June 30, 2020 and 2021, have been prepared in accordance with GAAP for interim financial statements and pursuant to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments have been made that are considered necessary for a fair statement of our financial position as of December 31, 2020 and June 30, 2021, our results of operations for the three and six months ended June 30, 2020 and 2021 and our cash flows for the six months ended June 30, 2020 and 2021. The condensed consolidated balance sheets as of December 31, 2020 have been derived from the Company’s audited consolidated financial statements. Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. Certain information and disclosures normally included in the notes to annual financial statements prepared in accordance with GAAP have been omitted from these interim financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s final prospectus (the “IPO Prospectus”) dated as of April 29, 2021, and filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended (the “Securities Act”).
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments, which potentially subject the Company to concentration of credit risk, consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company is exposed to credit risk in the event of default by the financial institutions holding our cash and cash equivalents that are recorded on our balance sheets. The Company mitigates its risk by investing in high-grade instruments and limiting the concentration in any one issuer, which limits its exposure. The Company has not experienced any losses since inception. The carrying amounts of cash and cash equivalents, prepaid expenses, accounts payable and accrued other liabilities are reasonable estimates of their fair value because of the short maturity of these items.
Equity Method Investments	Equity Method Investments The Company uses the equity method of accounting for equity investments if the investment provides the ability to exercise significant influence, but not control, over operating and financial policies of the investee. The Company’s proportionate share of the net income or loss of these investees is included in our Condensed Consolidated Statements of Comprehensive Loss. Judgment regarding the level of influence over each equity method investment includes considering key factors such as the Company’s ownership interest, legal form of the investee, representation on the board of directors, participation in policy-making decisions and material intra-entity transactions. The Company evaluates equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by the Company when reviewing an equity method investment for impairment include the length of time and the extent to which the fair value of the equity method investment has been less than cost, the investee’s financial condition and near-term prospects and the intent and ability to hold the investment for a period of time sufficient to allow for anticipated recovery. An impairment that is other-than temporary is recognized in the period identified. The Company accounts for distributions received from equity method investees under the “nature of the distribution” approach. Under this approach, distributions received from equity method investees are classified on the basis of the nature of the activity or activities of the investee that generated the distribution as either a return on investment (classified as cash inflows from operating activities) or a return of investment (classified as cash inflows from investing activities). The Company has made an accounting policy election, as a result of disposing of its equity method investment on June 24, 2021, to account for the contingent gains from the earnout provision and projects escrow release only when those amounts become realizable in the periods subsequent to the disposal date. (See Note. 6) Stock Based Compensation The Company recognizes compensation expense for all share-based payment awards made, including stock options and restricted stock, based on the estimated fair value of the award on the grant date, in the accompanying consolidated statements of operations over the requisite service period of the awards. The Company calculates the fair value of stock options using the Black-Scholes Option-Pricing model. The fair value of restricted stock grants represents the estimated fair value of the Company's common stock on the date of grant. The Company accounts for forfeitures as they occur. For service-based awards, stock-based compensation is recognized using the straight-line attribution approach over the requisite service period. For performance-based awards, stock-based compensation is recognized based on graded vesting over the requisite service period when the performance condition is probable of being achieved.
Stock-Based Compensation	Stock Based Compensation The Company recognizes compensation expense for all share-based payment awards made, including stock options and restricted stock, based on the estimated fair value of the award on the grant date, in the accompanying consolidated statements of operations over the requisite service period of the awards.

For service-based awards, stock-based compensation is recognized using the straight-line attribution approach over the requisite service period. For performance-based awards, stock-based compensation is recognized based on graded vesting over the requisite service period when the performance condition is probable of being achieved.
Revenue Recognition	Revenue Recognition The Company derives its revenue primarily from sale of: (1) Voyager Tracker and customized components of Voyager Tracker, (2) individual parts of Voyager Tracker for certain specific transactions, (3) shipping and handling services, (4) term-based software licenses, (5) maintenance and support services for the term-based software licenses, and (6) subscription services. Product revenue includes revenue from Voyager Tracker and customized components of Voyager Tracker, individual part sales for certain specific transactions, and sale of term-based software licenses. Service revenue includes revenue from shipping and handling services, subscription-based enterprise licensing model, and maintenance and support services in connection with the term-based software licenses. Voyager Tracker and individual parts of Voyager Tracker (including shipping and handling) The Company contracts with customers for sale of Voyager Trackers under two different types of arrangements: (1) Purchase Agreements and Equipment Supply Contracts (“Purchase Agreements”) and (2) sale of individual parts of the Voyager Tracker. The Company’s Purchase Agreements typically include two performance obligations- (1) Voyager Tracker or customized components of Voyager Tracker and (2) shipping and handling services. The deliverables included as part of the Voyager Tracker are predominantly accounted for as one performance obligation, as these deliverables are part of a combined promise to deliver a project. Voyager Tracker and customized components of Voyager Tracker performance obligations in the contract are satisfied over-time as work progresses for its custom assembled Voyager Tracker, utilizing an input measure of progress determined by cost-to-cost measures on these projects as this faithfully depicts the Company’s performance in transferring control. The revenue for shipping and handling services is recognized over-time based on shipping terms of the arrangements, as this faithfully depicts the Company’s performance in transferring control. The Company’s sale of individual parts of Voyager Tracker for certain specific transactions include multiple performance obligations consisting of individual parts of the Voyager Tracker. Revenue recognized for the Company’s part sales are recorded at a point in time and recognized when obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is in line with shipping terms. Term-based software license revenue Term-based software license revenue included under product revenue is primarily derived from sale of term-based software licenses that are deployed on the customers’ own servers and have significant standalone functionality. The revenue is recognized upon transfer of control to the customer. The control for term-based software licenses is transferred at the later of delivery to the customer or the software license start date. Term-based software license revenue is immaterial for the three and six month periods ended June 30, 2020 and June 30, 2021. Subscription and Maintenance and support services revenue Subscription revenue is derived from a subscription-based enterprise licensing model with contract terms typically ranging from one to two years and consists of subscription fees from the licensing of Subscription services. Subscription services revenue is immaterial for the three and six month periods ended June 30, 2020 and June 30, 2021. The hosted on-demand service arrangements do not provide customers with the right to take possession of the software supporting the hosted services. Services revenue includes maintenance and support service revenue related to term-based software licenses. Support revenue is derived from ongoing security updates, upgrades, bug fixes, and maintenance. A time-elapsed method is used to measure progress because the Company transfers control evenly over the contractual period. Accordingly, the fixed consideration related to these revenues is generally recognized on a straight-line basis over the contract term beginning on the date access is provided. Cost of Revenue Cost of revenue consists primarily of costs related to raw materials, freight and delivery, product warranty, and personnel costs (salaries, bonuses, benefits, and stock-based compensation). Personnel costs in cost of revenue include both direct labor costs as well as costs attributable to any individuals whose activities relate to the procurement, installment and delivery of the finished product and services. Deferred cost of revenue results from the timing differences between the costs incurred in advance of the satisfaction of all revenue recognition criteria consistent with our revenue recognition policy. Warranty We provide standard assurance type warranties with our Voyager Trackers for periods generally ranging from five to ten years. We record a provision for estimated warranty expenses, net of amounts recoverable from manufacturers, to cost of sales when we recognize revenue. These estimates are based on our historical experience and forward-looking factors including the expected nature and frequency of product failure rates and costs to address future claims. These estimates are inherently uncertain given our relatively short history of sales and changes to our historical or projected warranty experience may result in material changes to our warranty reserve in the future. We do not maintain general or unspecified reserves; all warranty reserves are related to specific projects. All actual or estimated material costs incurred in subsequent periods are charged to those established reserves. Remaining Performance Obligations Remaining performance obligations relate to contracts that have original expected durations of one year or less. Therefore, the transaction price allocated to performance obligations that are unsatisfied or partially satisfied as of the end of the reporting period are not required to be disclosed under ASC 606.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Standards In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 removes certain exceptions related to the approach for intra period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of GAAP. The Company adopted ASU 2019-12 in the first quarter of 2021, and the adoption had no material impact to the Company's consolidated financial statements. New Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 changes the impairment model for most financial assets and requires the use of an expected loss model in place of the currently used incurred loss method. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The Company is currently evaluating the impact that the adoption of ASU 2016-13 will have on its condensed consolidated financial statements and the Company plans to adopt in beginning of year 2023. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This standard provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The Company is currently evaluating the impact this adoption will have on the Company’s condensed consolidated financial statements and the Company plans to adopt in year 2022.
