PRELIMINARY PROSPECTUS

Up to 24,616,551 Shares of Class A Common Stock

This prospectus relates to the resale from time to time by the selling securityholders named in this prospectus (the “Selling Securityholders”) of up to an aggregate of 24,616,551 shares of Class A Common Stock (as defined below), including (i) 19,800,000 shares of Class A Common Stock underlying those certain convertible debentures (the “YA Convertible Debentures”) issued and issuable pursuant to a Securities Purchase Agreement, dated November 30, 2022, entered into by and between Rubicon Technologies, Inc. (“Rubicon”) and YA II PN, Ltd. (the “Yorkville Investor”), (ii) 443,341 shares of Class A Common Stock (the “Cowen Deferred Fee Shares”) issued to Cowen Investments II LLC (“Cowen”) in satisfaction of outstanding amounts owed to Cowen and Company, LLC for financial advisory services provided in connection with the Business Combination (as defined below), comprised of (a) 440,529 shares of Class A Common Stock issued to Cowen on November 18, 2022 and (b) 2,812 shares of Class A Common Stock issued to Cowen on December 6, 2022 (the “Cowen Deferred Fee Arrangement”) and (iii) 4,373,210 shares of Class A Common Stock (the “Moelis Deferred Fee Shares”) issued to Moelis & Company Group LP (“Moelis”) on December 13, 2022 in satisfaction of outstanding amounts owed to Moelis & Company LLC for financial advisory services provided in connection with the Business Combination (the “Moelis Deferred Fee Arrangement”).

The shares of Class A Common Stock being offered for resale in this prospectus represent, as of the date of this prospectus, approximately 12.9% of our total outstanding shares of Common Stock (as defined below) (after giving effect to the conversion of the YA Convertible Debentures into all of the YA Conversion Shares (as defined below) registered for resale in this prospectus). The sale of some or all of the securities being offered in this prospectus, following the satisfaction of any applicable conditions, could have adverse effects on the market for our Class A Common Stock, including increasing volatility, limiting the availability of an active market and/or resulting in a significant decline in the public trading price. Despite any potential adverse effects, the Selling Securityholders may still experience a positive rate of return on the securities they purchased due to the differences in the purchase prices at which they purchased the securities described above. See the sections entitled “Summary—Information Related to Offered Securities” and “Risk Factors — Risks Related to Ownership of Our Securities.”

We will not receive any proceeds from the sale of shares of Class A Common Stock by the Selling Securityholders pursuant to this prospectus.

Each Selling Securityholder will pay any underwriting discounts and commissions and expenses incurred by the Selling Securityholder for brokerage, accounting, tax or legal services or any other expenses incurred by the Selling Securityholder in disposing of its securities; provided, however, that pursuant to the Deferred Fee Arrangements and the YA Registration Rights Agreement (each as defined below), we will bear the costs, fees and expenses incurred in effecting the registration of the securities covered by this prospectus, including all registration and filing fees, New York Stock Exchange (“NYSE”) listing fees and fees and expenses of our counsel and our independent registered public accounting firm, and certain fees incurred in connection with a Selling Securityholder’s exercise of certain block trade, piggyback and underwritten offering rights.

We are registering the securities for resale pursuant to the Selling Securityholders’ registration rights under certain agreements between us and the Selling Securityholders. Our registration of the securities covered by this prospectus does not mean that either we or the Selling Securityholders will offer or sell any of the shares of Class A Common Stock. The Selling Securityholders or their permitted transferees may offer, sell or distribute all or a portion of their shares of Class A Common Stock publicly or through private transactions at prevailing market prices or at negotiated prices. We provide more information about how the Selling Securityholders may sell the Class A Common Stock in the section entitled “Plan of Distribution.”

TABLE OF CONTENTS

INTRODUCTORY NOTE REGARDING THE BUSINESS COMBINATION AND CERTAIN OTHER TRANSACTIONS

On August 15, 2022 (the “Closing” and such date, the “Closing Date”), we consummated the business combination (the “Business Combination”) pursuant to that certain Agreement and Plan of Merger, dated December 15, 2021 (the “Merger Agreement”), by and among Founder SPAC, a Cayman Islands exempted company (together with its successors, including after the Domestication (as defined below), “Founder”), Ravenclaw Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of Founder (“Merger Sub”), Ravenclaw Merger Sub Corporation 1, a Delaware corporation and wholly owned subsidiary of Founder (“Merger Sub Inc. 1”), Ravenclaw Merger Sub Corporation 2, a Delaware corporation and wholly owned subsidiary of Founder (“Merger Sub Inc. 2”), Ravenclaw Merger Sub Corporation 3, a Delaware corporation and wholly owned subsidiary of Founder (“Merger Sub Inc. 3” and, together with Merger Sub Inc. 1 and Merger Sub Inc. 2, each a “Blocker Merger Sub”), Boom Clover Business Limited, a British Virgin Islands corporation (“Blocker Company 1”), NZSF Frontier Investments Inc., a Delaware corporation (“Blocker Company 2”), PLC Blocker A LLC, a Delaware limited liability company (“Blocker Company 3” and, together with Blocker Company 1 and Blocker Company 2, each a “Blocker Company” and collectively, the “Blocker Companies”), and Rubicon Technologies, LLC, a Delaware limited liability company (“Holdings LLC”).

Pursuant to the Merger Agreement, among other things, (a) Founder deregistered as an exempted company under the Cayman Islands Companies Act (As Revised) and continued and domesticated as a Delaware corporation under Section 388 of the Delaware General Corporation Law (the “Domestication”), and in connection therewith, changed its name from Founder SPAC to Rubicon Technologies, Inc. (“Rubicon”), (b) Merger Sub merged with and into Holdings LLC (the “Merger”), with Holdings LLC surviving the Merger as a wholly owned subsidiary of Rubicon, and (c) in a series of sequential two-step mergers (i) each Blocker Merger Sub merged with and into its corresponding Blocker Company, with each Blocker Company surviving as a wholly owned subsidiary of Rubicon, following which (ii) each surviving Blocker Company merged with and into Rubicon, with Rubicon surviving the merger (collectively the “Blocker Mergers” and, together with the Merger, the “Mergers”). The transactions contemplated by the Merger Agreement, including the Mergers, are collectively referred to in this prospectus as the “Business Combination”.

As a result of and upon the effective time of the Domestication, (a) each then-issued and outstanding Class A ordinary share, par value $0.0001 per share, of Founder (“Founder Class A Shares”) automatically converted into one share of Class A common stock, par value $0.0001 per share, of Rubicon (“Class A Common Stock”), (b) each then-issued and outstanding Class B ordinary share, par value $0.0001 per share, of Founder (“Founder Class B Shares” and, together with Founder Class A Shares, “Founder Ordinary Shares”), converted into one share of Class A Common Stock, pursuant to the Sponsor Agreement, dated December 15, 2021, by and among Founder, Founder SPAC Sponsor LLC (“Sponsor”), Holdings LLC, and certain insiders of Founder (the “Sponsor Agreement”), (c) each then-issued and outstanding public warrant of Founder, each representing a right to acquire one Founder Class A Share for $11.50 (a “Founder Public Warrant”), converted automatically, on a one-for-one basis, into a public warrant of Rubicon (a “Public Warrant”) that represents a right to acquire one share of Class A Common Stock for $11.50 pursuant to Section 4.5 of the Warrant Agreement, dated October 14, 2021, by and between Founder and Continental Stock Transfer and Trust Company (as amended by the Warrant Agreement Amendment (as defined below), the “Warrant Agreement”), (d) each then-issued and outstanding private placement warrant of Founder, each representing a right to acquire one Founder Class A Share for $11.50 (a “Founder Private Placement Warrant”), converted automatically, on a one-for-one basis, into a private placement warrant of Rubicon (the “Private Warrant” and together with the Public Warrants, the “Warrants”) that represents a right to acquire one share of Class A Common Stock for $11.50 pursuant to Section 4.5 of the Warrant Agreement, and (e) each then-issued and outstanding unit of Founder, each representing a Founder Class A Share and one-half of a Founder Public Warrant (a “Founder Unit”), that had not been previously separated into the underlying Founder Class A Share and one-half of one Founder Public Warrant upon the request of the holder thereof, was separated and automatically converted into one share of Class A Common Stock and one-half of one Public Warrant. No fractional Public Warrants were issued upon separation of the Founder Units. In addition, the certificate of incorporation of Rubicon (the “Charter”) authorizes Class V common stock, par value $0.0001 per share (“Class V Common Stock” and together with the Class A Common Stock, “Common Stock”). Class A Common Stock is entitled to economic rights and one vote per share and Class V Common Stock is entitled to one vote per share with no economic rights. In connection with the consummation of the Business Combination, Continental Stock Transfer and Trust Company and Rubicon amended the Warrant Agreement, to among other things, reflect the change in name and the Domestication (the “Warrant Agreement Amendment”).

Following the Merger, among other things, Rubicon was issued Class A Units in Holdings LLC (“Class A Units”) and all preferred units, common units, and incentive units of Holdings LLC (including such convertible instruments, the “Rubicon Interests”) outstanding as of immediately prior to the Merger were automatically recapitalized into Class A Units and Class B Units of Holdings LLC (“Class B Units”), as authorized by the Eighth Amended and Restated Limited Liability Company Agreement of Holdings LLC (“A&R LLCA”) that was adopted at the time of the Merger. Following the Blocker Mergers, (a) holders of Rubicon Interests immediately before the Closing, other than the Blocker Companies (the “Blocked Unitholders”), were issued Class B Units (the “Rubicon Continuing Unitholders”), (b) Rubicon Continuing Unitholders were issued a number of shares of Class V Common Stock equal to the number of Class B Units issued to the Rubicon Continuing Unitholders, (c) Blocked Unitholders were issued shares of Class A Common Stock (as a result of the Blocker Mergers), and (d) following the adoption of the equity incentive award plan of Rubicon adopted at the Closing (the “2022 Plan”) and the effectiveness of a registration statement on Form S-8 filed by Rubicon on October 19, 2022, holders of phantom units of Holdings LLC immediately prior to the Closing (“Rubicon Phantom Unitholders”) and those current and former directors, officers and employees of Holdings LLC entitled to certain cash bonuses (the “Rubicon Management Rollover Holders”) were awarded restricted stock units of Rubicon (“RSUs”) or deferred stock units (“DSUs”) (in each case depending on their employment status at the time of the award), and such RSUs and DSUs will vest into shares of Class A Common Stock on February 11, 2023, the date that is 180 days following the Closing. In addition to the securities issuable at the Closing and pursuant to the 2022 Plan, certain of the Rubicon Management Rollover Holders received one-time cash payments (the “Cash Transaction Bonuses”). In addition, pursuant to the Merger Agreement, (i) Blocked Unitholders immediately before the Closing received a right to receive a pro rata portion of 1,488,519 shares of Class A Common Stock (the “Earn-Out Class A Shares”) and (ii) Rubicon Continuing Unitholders immediately before the Closing received a right to receive a pro rata portion of 8,900,840 Class B Units (“Earn-Out Units”) and an equivalent number of shares of Class V Common Stock (“Earn-Out Class V Shares”, and together with Earn-Out Class A Shares and Earn-Out Units, “Earn-Out Interests”), in each case, depending upon the performance of Class A Common Stock during the five (5) year period after the Closing.

Concurrent with the execution of the Merger Agreement, Founder entered into certain Subscription Agreements, dated as of December 15, 2021, by and between Founder, on the one hand, and certain investors (“PIPE Investors”) on the other hand (collectively, the “Subscription Agreements”), pursuant to which, among other things, concurrent with the Closing, Rubicon issued and sold to the PIPE Investors an aggregate of 11,100,000 shares of Class A Common Stock, at a per share price of $10.00, for an aggregate purchase price of $111,000,000, on the terms and subject to the conditions set forth therein. On August 12, 2022, certain of the current PIPE Investors and new PIPE Investors entered into additional Subscription Agreements to purchase an aggregate of 1,000,000 shares of Class A Common Stock, at a per share price of $10.00, for an aggregate purchase price of $10,000,000 (together with the original Subscription Agreements, the “PIPE Financing” or “PIPE Investment”).

Concurrent with the execution of the Merger Agreement, the Sponsor and certain insiders of Founder (the “Insiders”) entered into the Sponsor Agreement with Founder and Holdings LLC, pursuant to which the Sponsor and the Insiders agreed, among other things, not to transfer any Class A Common Stock or Private Warrants (or any shares of Class A Common Stock issuable upon conversion or exercise thereof) until the earlier of (i) February 11, 2023 (180 days after the Closing Date) and (ii) the date after the Closing Date on which Rubicon completes a liquidation, merger, or similar transaction that results in all of Rubicon’s stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property. In the event that Rubicon waives, releases, or terminates a Lock-Up Agreement (as defined below) with respect to any shares or holders, the Sponsor and the Insiders will be granted a similar waiver, release, or termination with respect to a pro rata portion of the securities held by them and subject to the foregoing restrictions.

Concurrent with the execution of the Merger Agreement, certain holders of Rubicon Interests entered into lock-up agreements with Founder and Holdings LLC (the “Lock-Up Agreements”). Pursuant to the Lock-Up Agreements, each holder agreed to certain transfer restrictions with respect to the securities such holder received as transaction consideration pursuant to the Merger Agreement, until the earlier of (i) February 11, 2023 (180 days after the Closing Date) and (ii) the date after the Closing on which Rubicon completes a liquidation, merger, or similar transaction that results in all of Rubicon’s stockholders having the right to exchange their equity holdings for cash, securities or other property. The holders of Rubicon Interests further agreed pursuant to the Lock-Up Agreements not to exchange Class B Units for Class A Common Stock during this restricted period. In the event that Rubicon waives, releases, or terminates the lock-up provision in any other Lock-Up Agreement, then the other holders subject to the Lock-Up Agreements will be granted a similar waiver, release or termination with respect to a pro rata portion of the securities held thereby and subject to the foregoing restrictions. Between entry into the Merger Agreement and Closing, additional holders of Rubicon Interests entered into Lock-Up Agreements on the same terms.

Pursuant to that certain Rubicon Equity Investment Agreement entered into on May 25, 2022 (the “Rubicon Equity Investment Agreement”), by and among Holdings LLC and certain of its equityholders (the “New Equity Holders”) who are affiliated with Andres Chico (a member of our board of directors) and Jose Miguel Enrich (a beneficial owner of greater than 10% of the issued and outstanding Common Stock). Concurrent with the Closing and in satisfaction of the obligations thereunder, (a) Rubicon caused to be issued to the New Equity Holders 880,000 Class B Units pursuant to the Merger Agreement, (b) Rubicon issued 160,000 shares of Class A Common Stock to the New Equity Holders, and (c) Sponsor forfeited 160,000 Founder Class B Shares.

In connection with the extraordinary general meeting of Founder held on August 2, 2022 to approve the Business Combination and other related matters (the “Founder Special Meeting”), holders of 31,260,777 Founder Class A Shares (or approximately 98.8% of the issued and outstanding Founder Class A Shares on such date) exercised their right to redeem those shares for cash at a price of approximately $10.176 per share. On August 4, 2022, Founder, Holdings LLC and ACM ARRT F LLC, a Delaware limited liability company (“ACM Seller”, together with such other parties to which obligations of ACM Seller were novated, the “FPA Sellers”), entered into an agreement (the “Forward Purchase Agreement”) for an OTC Equity Prepaid Forward Transaction. The primary purpose of entering into the Forward Purchase Agreement was to help ensure that Founder’s initial listing application with the NYSE was approved, increasing the likelihood that the transaction would close. Pursuant to the Forward Purchase Agreement, prior to the consummation of the Business Combination, at an average purchase price of $10.15 per share, the FPA Sellers purchased an aggregate of 7,082,616 Founder Class A Shares from certain holders that elected to redeem Founder Class A Shares for cash and reversed such election (the “Redeeming Holders”), of which 666,667 shares were Share Consideration (as defined in the Forward Purchase Agreement). Pursuant to the Forward Purchase Agreement, each of the FPA Sellers waived its redemption rights under the governing documents of Founder in connection with the Closing. As a result of the Forward Purchase Agreement, at the Business Combination, holders of 24,178,161 Founder Class A Shares (or approximately 76.5% of the issued and outstanding Founder Class A Shares on such date) exercised their right to redeem those shares for cash at a price of approximately $10.176 per share, resulting in an aggregate redemption payment of approximately $246.0 million from Founder’s trust account. Following these redemptions, at the Closing we received approximately $75.8 million from Founder’s trust account, without accounting for the payment of transaction costs, payments under the Forward Purchase Agreement and Cash Transaction Bonuses. As a result of consummation of the Mergers and accounting for the foregoing redemption payments and receipt of funds from Founder’s trust account, we received approximately $73.8 million in net proceeds from the Business Combination after accounting for our payment of approximately $25.4 million of transaction costs, aggregate payments of $68.7 million by us to the FPA Sellers under the Forward Purchase Agreement, net proceeds of $121.0 million from the PIPE Investment, and the payment by us of an aggregate of $28.9 million in Cash Transaction Bonuses.

On August 15, 2022, prior to the Closing, Founder, Sponsor, and Holdings LLC entered into a forfeiture agreement (the “Sponsor Forfeiture Agreement”), whereby Sponsor forfeited 1,000,000 Founder Class B Shares immediately prior to the Closing.

At the Closing, Rubicon and Holdings LLC entered into a Tax Receivable Agreement (the “Tax Receivable Agreement” or “TRA”) with Rubicon Continuing Unitholders and Blocked Unitholders (the “TRA Holders”). Pursuant to the Tax Receivable Agreement, among other things, Rubicon is required to pay to the TRA Holders 85% of certain of Rubicon’s realized (or in certain cases deemed realized) tax savings as a result of certain tax benefits related to the transactions contemplated by the Merger Agreement and future exchanges of Class B Units for Class A Common Stock or cash.

At the Closing, Founder entered into an amended and restated registration rights agreement (the “A&R Registration Rights Agreement”) with the Sponsor, Holdings LLC, and certain holders of Rubicon Interests (the “Rubicon Legacy Holders” and together with the Sponsor and any persons who thereafter become party to the agreement, the “RRA Holders”). Pursuant to the A&R Registration Rights Agreement, within 30 days of the Closing Date, Rubicon was required to file a registration statement under the Securities Act of 1933, as amended (the “Securities Act”), registering for resale (i) all outstanding shares of Class A Common Stock held by the RRA Holders immediately following the Closing, (ii) all shares of Class A Common Stock issuable upon exercise, conversion or exchange of any option, warrant or convertible security held directly or indirectly by a RRA Holder immediately following the Closing, (iii) any Warrants or shares of Class A Common Stock that may be acquired by the RRA Holders upon the exercise of a Warrant or other right to acquire Class A Common Stock held by a RRA Holder immediately following the Closing, (iv) any shares of Class A Common Stock or Warrants otherwise acquired or owned by a RRA Holder following the date of the A&R Registration Rights Agreement to the extent that such securities are “restricted securities” (as defined in Rule 144 promulgated under the Securities Act (“Rule 144”)) or are otherwise held by an “affiliate” (as defined in Rule 144) of Rubicon, and (v) any other equity security of Rubicon or its subsidiaries issued or issuable with respect to any of the foregoing pursuant to a reorganization, stock split, stock dividend, or like transaction. Rubicon thereafter is required to maintain a registration statement that is continuously effective and to cause the registration statement to regain effectiveness in the event that it ceases to be effective. The RRA Holders have certain “demand” and “piggyback” registration rights under the agreement. Rubicon will bear the expenses incurred in connection with the filing of any registration statements pursuant to the A&R Registration Rights Agreement.

On August 31, 2022, Rubicon entered into a Standby Equity Purchase Agreement (the “SEPA”) with the Yorkville Investor, pursuant to which (a) Rubicon issued the Yorkville Investor 200,000 shares of Class A Common Stock, which represented an initial up-front commitment fee (the “Yorkville Commitment Shares”), and (b) assuming satisfaction of certain conditions and subject to the limitations set forth in the SEPA, Rubicon has the right, from time to time to issue and sell to the Yorkville Investor up to $200.0 million in shares of Class A Common Stock until the earlier of September 1, 2025 (the first day of the month next following the 36-month anniversary of the SEPA) or the date on which the facility has been fully utilized, in each case, with such sales first subject to the Securities and Exchange Commission (the “SEC”) declaring effective a registration statement covering the resale of such shares of Class A Common Stock (such registration statement, the “SEPA Registration Statement”).

On November 30, 2022, Rubicon and the Yorkville Investor entered into a letter agreement to amend the SEPA (the “SEPA Amendment”). Pursuant to the SEPA Amendment, the parties agreed that Rubicon will not file the SEPA Registration Statement until there is an effective registration statement covering the resale of at least 18,000,000 YA Conversion Shares (as defined below). The registration statement of which this prospectus forms a part is being filed in respect of this obligation.

On November 30, 2022, Rubicon terminated the Forward Purchase Agreement with the FPA Sellers pursuant to termination agreements with each of ACM Seller and Vellar Opportunity Fund SPV LLC – Series 2 (“Vellar”), an FPA Seller that was assigned and novated a portion of the Forward Purchase Agreement pursuant to that certain Assignment and Novation Agreement, dated August 5, 2022, by and among Rubicon, Holdings LLC, Vellar and ACM Seller. Pursuant to the termination agreement with ACM Seller (the “Atalaya Termination Agreement”), Rubicon, among other things, made a one-time $6.0 million cash payment to ACM Seller and ACM Seller forfeited, for no additional consideration, 2,222,119 shares of Class A Common Stock and further agreed to certain lock-up and transfer restrictions with respect to the remaining 500,000 shares of Class A Common Stock that it holds pursuant to the Forward Purchase Agreement. Pursuant to the termination agreement with Vellar (the “Vellar Termination Agreement” and, together with the Atalaya Termination Agreement, the “FPA Termination Agreements”), Vellar retained 1,640,848 shares of Class A Common Stock (the “Previously Owned Shares”) it holds pursuant to the Forward Purchase Agreement (subject to certain lock-up and transfer restrictions) and Rubicon agreed to make a $2.0 million payment to Vellar which can be settled, at Rubicon’s sole option, in cash or shares of Class A Common Stock, subject to certain adjustments.

On November 30, 2022, we entered into a securities purchase agreement (the “YA SPA”) with the Yorkville Investor, whereby we agreed to issue and sell to the Yorkville Investor (i) YA Convertible Debentures in the aggregate principal amount of up to $17.0 million, which are convertible into shares of Class A Common Stock (as converted, the “YA Conversion Shares”), and (ii) a pre-funded common stock purchase warrant (the “YA Warrant”), which is exercisable into $20.0 million of shares of Class A Common Stock (the “YA Warrant Shares”), in each case, on the terms and subject to the conditions set forth therein. Upon signing the YA SPA, we (i) issued and sold to the Yorkville Investor (a) a YA Convertible Debenture in the principal amount of $7.0 million for a purchase price of $7.0 million (the “First YA Convertible Debenture”), and (b) the YA Warrant for a pre-funded purchase price of $6.0 million, and (ii) paid the Yorkville Investor a cash commitment fee equal to $2.04 million, with such amount being deducted from the proceeds of the First YA Convertible Debenture, netting Rubicon approximately $10.96 million in total proceeds. Pursuant to the YA SPA, the parties further agreed that we will issue and sell to the Yorkville Investor and the Yorkville Investor will purchase from us a second YA Convertible Debenture in the principal amount of $10.0 million for a purchase price of $10.0 million (the “Second YA Convertible Debenture”), upon the satisfaction of certain conditions. The YA Convertible Debentures have a maturity date of May 30, 2024 and accrue interest at the rate of 4% per annum (provided that the interest rate will increase to 15% per annum in the event of certain defaults). The YA Warrant and YA Convertible Debentures may be exercised or converted, as applicable, into shares of Class A Common Stock, in each case to be issued at a variable rate dependent on the future volume-weighted average price (“VWAP”) of the Class A Common Stock, and subject to certain other adjustments as set forth therein. Concurrent with the entry into the YA SPA, we entered into a registration rights agreement with the Yorkville Investor (the “YA Registration Rights Agreement”), whereby, we agreed to, among other things, register for resale all of the YA Conversion Shares and YA Warrant Shares.

On December 16, 2022, Rubicon entered into a securities purchase agreement (the “Insider Securities Purchase Agreement”) with various investors comprised of members of Rubicon’s management team and board of directors (the “Insider Investors”). Pursuant to the Insider Securities Purchase Agreement, Rubicon agreed to issue and sell to the Insider Investors convertible debentures (the “Insider Convertible Debentures”) in the aggregate principal amount of up to $17.0 million, net of an original issuance discount of $2.0 million, which are convertible into shares of Class A Common Stock (the “Insider Conversion Shares”), which Insider Convertible Debentures may be purchased by the Insider Investors over the course of a first closing or second closing. The Insider Securities Purchase Agreement contained customary representations, warranties, and covenants for the sale and purchase of the Insider Convertible Debentures.

At the first closing, which closed on December 16, 2022, the Insider Investors purchased Insider Convertible Debentures in an aggregate amount of $10.5 million in United States dollars, net of an original issuance discount of $1.4 million, for a total principal amount of $11.9 million in Insider Convertible Debentures. At the second closing, Rubicon will issue Insider Convertible Debentures with an aggregate value of no less than $4.0 million and no greater than $5.0 million, to certain third-party investors, as designated thereby at the second closing. The Insider Convertible Debentures have a maturity date of June 16, 2024, 18 months after issuance, and accrue interest at the rate of 6% per annum (provided that the interest rate will increase to 12% per annum in the event of certain defaults). The Insider Convertible Debentures may be converted into shares of Class A Common Stock at an initial conversion price equal to the lower of 110% of: (i) the average closing price of Class A Common Stock for the five (5) trading days immediately preceding the date of the respective closing or (ii) the closing price of Class A Common Stock immediately preceding the date of the respective closing, subject to adjustments as further specified in the Insider Convertible Debentures. The Insider Convertible Debentures will be fully repayable in cash upon maturity. Concurrent with the entry into the Insider Securities Purchase Agreement, we entered into (i) a registration rights agreement (the “Insider Registration Rights Agreement”), pursuant to which Rubicon agreed to file a registration statement with the SEC registering the resale of Insider Conversion Shares within 45 days of the first closing, and to cause any such registration statement to become effective within 120 days after filing, and (ii) a lockup agreement (the “Insider Lockup Agreement”), pursuant to which the Insider Investors agreed to not offer, sell, or otherwise dispose of, directly or indirectly, any Insider Conversion Shares. As of the filing of this prospectus, Rubicon has received $3.5 million of proceeds for the Insider Convertible Debentures.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including statements about the anticipated benefits of the Business Combination and the financial condition, results of operations, earnings outlook, and prospects of Rubicon. Forward-looking statements appear in a number of places in this prospectus including, without limitation, in the sections titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business.” In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Forward-looking statements are typically identified by words such as “plan,” “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “would” and other similar words and expressions, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements involve a number of risks, uncertainties or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. You should understand that the following important factors, in addition to those factors described elsewhere in this prospectus, could affect the future results of Rubicon and could cause those results or other outcomes to differ materially from those expressed or implied in such forward-looking statements, including Rubicon’s ability to:

These and other factors that could cause actual results to differ from those implied by the forward-looking statements in this prospectus are more fully described under the heading “Risk Factors” and elsewhere in this prospectus. Forward-looking statements are not guarantees of performance and speak only as of the date hereof. The forward-looking statements are based on the current and reasonable expectations of Rubicon’s management but are inherently subject to uncertainties and changes in circumstances and their potential effects and speak only as of the date of such statements. There can be no assurance that future developments will be those that have been anticipated or that we will achieve or realize these plans, intentions or expectations.

All forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by the foregoing cautionary statements. The Company undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

In addition, statements of belief and similar statements reflect the beliefs and opinions of the Company on the relevant subject. These statements are based upon information available to the Company as of the date of this prospectus, and while the Company believes such information forms a reasonable basis for such statements, such information may be limited or incomplete, and statements should not be read to indicate that the Company has conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you are cautioned not to unduly rely upon these statements.

RISK FACTORS

Investing in our securities involves substantial risks. Before you make a decision to buy our securities, in addition to the risks and uncertainties discussed below you should carefully consider the specific risks and other information set forth in this prospectus, including “Cautionary Note Regarding Forward-Looking Statements,” “Unaudited Pro Forma Condensed Combined Financial Information,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and the related notes thereto included elsewhere in this prospectus. If any of these risks actually occur, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our securities could decline, and you could lose all or part of your investment. Additionally, the risks and uncertainties described in this prospectus or any prospectus supplement are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

Risks Related to Our Business and Industry

We have a history of net losses and project net losses in future periods. We may not appropriately manage our expenses, nor achieve nor maintain profitability in the future.

We have experienced net losses in each year since inception, including net losses of $73.2 million and $58.6 million for the fiscal years ended December 31, 2021 and 2020, respectively, and $263.7 million and $42.8 million for the nine months ended September 30, 2022 and 2021, respectively, and we may incur net losses in the future. While we project net losses to continue in future periods, it is difficult for us to predict our future results of operations, and we expect our operating expenses to increase significantly over the next several years as we continue to hire additional personnel, expand our operations and infrastructure, integrate completed acquisitions, make and integrate future acquisitions and invest in product development. In addition to the expected costs to grow our business, we also expect to incur significant additional legal, accounting and other expenses as a public company. Our indebtedness also bears interest at rates as high as 15%, which requires us to commit significant amounts to interest expense. If we fail to increase our revenue to offset the increases in our operating expenses, we may not achieve or sustain profitability in the future.

We may be unable to manage our growth effectively.

Our growth strategy places significant demands on our financial, operational and management resources. To continue our growth, we may need to add administrative, managerial and other personnel, and may need to make additional investments in operations and systems and this expansion will require us to increase our spending on working capital. We cannot assure you that we will be able to find and train qualified personnel, or do so on a timely basis, or to expand or otherwise modify our operations and systems to the extent, and in the time, required, or that we will be able to fund this expansion and increased spending on working capital from operating cash flows, debt or equity financing or other sources.

We are eligible to be treated as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including, but not limited to, (1) not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, which we refer to as the Sarbanes-Oxley Act or “SOX”, (2) reduced disclosure obligations regarding executive compensation in this prospectus and our periodic reports and proxy statements and (3) exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier, including if the market value of our common stock held by non-affiliates exceeds $700.0 million as of any June 30 before that time or if we have total annual gross revenue of $1.0 billion or more during any fiscal year before that time, in which cases we would no longer be an emerging growth company as of the following December 31 or, if we issue more than $1.0 billion in non-convertible debt during any three-year period before that time, we would cease to be an emerging growth company immediately. Even after we no longer qualify as an emerging growth company, we may still qualify as a “smaller reporting company” which would allow us to take advantage of many of the same exemptions from disclosure requirements, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We cannot predict if investors will find our Class A Common Stock less attractive because we may rely on these exemptions. If some investors find our Class A Common Stock less attractive as a result, there may be a less active trading market for our Class A Common Stock and our stock price may be more volatile.

Our independent registered public accounting firm is not required to formally attest to the effectiveness of our internal control over financial reporting until the later of our second annual report or the first annual report required to be filed with the SEC following the date that we are no longer an “emerging growth company” as defined in the JOBS Act. We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal controls in the future.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected, and expect to continue, to avail ourselves of this exemption from new or revised accounting standards and, therefore, will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

We are an emerging growth company and smaller reporting company and as such are subject to various risks unique only to emerging growth companies and smaller reporting companies, including but not limited to, no requirement to provide an assessment of the effectiveness of internal controls over financial reporting.

We are an “emerging growth company” as defined in the JOBS Act. We will remain an emerging growth company until the earlier of (i) December 31, 2026, the last day of the fiscal year following the fifth anniversary of the date of the first sale of Founder’s initial public offering (the “IPO”); (ii) the last day of the fiscal year in which we have total annual gross revenues of $1.0 billion or more; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under applicable SEC rules.

We expect that we will remain an emerging growth company for the foreseeable future but cannot retain our emerging growth company status indefinitely and will no longer qualify as an emerging growth company on or before December 31, 2026. References herein to “emerging growth company” have the meaning associated with it in the JOBS Act.

For so long as we remain an emerging growth company, we are permitted and intend to rely on exemptions from specified disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include:

Additionally, as an emerging growth company and smaller reporting company our status as such carries various unique risks such as the risk that our financial statements may not be comparable to those of other public companies, and the risk that we will not be required to provide an assessment of the effectiveness of our internal controls over financial reporting until our second annual report following our initial public offering.

For as long as we continue to be an emerging growth company, we expect that we will take advantage of the reduced disclosure obligations available to us as a result of that classification. We have taken advantage of certain of those reduced reporting burdens in this prospectus. Accordingly, the information contained herein may be different than the information you receive from other public companies in which you hold stock.

An emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected to avail ourselves of this extended transition period and, as a result, we will not be required to adopt new or revised accounting standards on the dates on which adoption of such standards is required for other public reporting companies.

We are also a “smaller reporting company” as defined in Rule 12b-2 of the Exchange Act, and have elected to take advantage of certain of the scaled disclosure available for smaller reporting companies.

If we fail to put in place appropriate and effective internal control over financial reporting and disclosure controls and procedures, we may suffer harm to our reputation and investor confidence levels.

Prior to the consummation of the Business Combination, we were not required to evaluate our internal control over financial reporting in a manner that meets the standards of publicly traded companies required by Section 404. As a public company, we have significant requirements for enhanced financial reporting and internal controls.

The process of designing and implementing effective internal controls is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a system of internal controls that is adequate to satisfy our reporting obligations as a public company. If we are unable to establish or maintain appropriate internal financial reporting controls and procedures, it could cause us to fail to meet our reporting obligations on a timely basis, result in material misstatements in our consolidated financial statements, and harm our operating results. In addition, we will be required, pursuant to Section 404, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting in our Annual Report on Form 10-K for the fiscal year ending December 31, 2022. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP. This assessment will need to include disclosure of any material weaknesses identified by our management in its internal control over financial reporting. The rules governing the standards that must be met for our management to assess our internal control over financial reporting are complex and require significant documentation, testing, and possible remediation. Testing and maintaining internal controls may divert our management’s attention from other matters that are important to our business. Our independent registered public accounting firm is not required to formally attest to the effectiveness of our internal control over financial reporting until the later of our second annual report or the first annual report required to be filed with the SEC following the date that we are no longer an “emerging growth company” as defined in the JOBS Act.

In connection with the implementation of the necessary procedures and practices related to internal control over financial reporting, we may identify deficiencies that we may not be able to remediate in time to meet the deadline imposed by SOX for compliance with the requirements of Section 404. In addition, we may encounter problems or delays in completing the remediation of any deficiencies identified by our independent registered public accounting firm in connection with the issuance of their attestation report. Our testing, or the subsequent testing (if required) by our independent registered public accounting firm, may reveal deficiencies in our internal control over financial reporting that are deemed to be material weaknesses. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the entity’s financial statements will not be prevented or detected on a timely basis. Any material weaknesses could result in a material misstatement of our annual or quarterly consolidated financial statements or disclosures that may not be prevented or detected. The existence of any material weakness would require management to devote significant time and incur significant expense to remediate any such material weakness, and management may not be able to remediate any such material weakness in a timely manner.

If we fail to implement the requirements of Section 404 in the required timeframe once we are no longer an emerging growth company or a smaller reporting company, we may be subject to sanctions or investigations by regulatory authorities, including the SEC and NYSE. Furthermore, if we are unable to conclude that our internal controls over financial reporting are effective, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our securities could decline, and we could be subject to sanctions or investigations by regulatory authorities. Failure to implement or maintain effective internal control over financial reporting and disclosure controls and procedures required of public companies could also restrict our future access to the capital markets.

The waste and recycling industry is highly competitive, and if we cannot successfully compete in the marketplace, our business, financial condition and operating results may be materially adversely affected.

Our industry is highly competitive. Competition in the waste and recycling industry is typically based on the quality of services, ease of doing business, and price. We encounter intense competition from governmental, quasi-governmental and private sources in all aspects of our operations. We principally compete with large national waste management companies, counties and municipalities that maintain and manage their own waste collection and disposal operations and regional and local companies of varying sizes and financial resources. Our industry also includes companies that specialize in certain discrete areas of waste management, operators of alternative disposal facilities, companies that seek to use parts of the waste stream as feedstock for renewable energy and other by-products, and other waste brokers that rely upon haulers in local markets to address customer needs. Any shortage of haulers or negative impact on our relationship with haulers in local markets may adversely affect our ability to serve our customers and result in a negative impact to our customer relationships, revenue and growth potential. In recent years, the waste and recycling industry has seen some additional consolidation, which has reduced the number of haulers, though the industry remains intensely competitive.

We compete with national waste management companies who may have significantly greater resources than we do and some of whom have and may internally develop services and solutions similar to ours. Counties and municipalities may have financial competitive advantages to us because of their ability to collect tax revenues and issue tax-exempt financing with the associated governmental underwriting bond ratings. In addition, some of our competitors may have lower costs, debt levels or financial expectations than we do, allowing them to reduce their prices to expand their reach or to win competitively-bid contracts, including large national accounts and exclusive franchise arrangements with municipalities. When this happens, we may lose customers and be unable to execute our pricing strategy, resulting in a negative impact to our revenue growth from yield on base business. Any failure to effectively compete would adversely affect our business, financial condition and results of operations.

Weakness in the U.S. economy may expose us to credit risk for amounts due from governmental entities, large national accounts, industrial customers and others.

Weakness in the U.S. economy, including contractions caused by the COVID-19 pandemic, reduces the amount of taxes collected by various governmental entities. We provide services to a number of these entities, including numerous municipalities. These governmental entities may suffer financial difficulties resulting from a decrease in tax revenue and may ultimately be unable or unwilling to pay amounts owed to us. In addition, weakness in the economy may cause other customers, including our large national accounts, or industrial or environmental services clients, to suffer financial difficulties and ultimately to be unable or unwilling to pay amounts owed to us. Purchasers of our recyclable commodities can be particularly vulnerable to financial difficulties in times of commodity price volatility. The inability of our customers to pay us in a timely manner or to pay increased rates, particularly governmental entities and large national accounts, could negatively affect our business, financial condition and results of operations.

The COVID-19 pandemic has adversely affected our business and may continue to do so in the future.

During 2021 and continuing into 2022, federal, state and local governments throughout North America, Europe, Asia and other parts of the world have imposed varying degrees of restriction on social, commercial and economic activity to slow the spread of COVID-19. The pandemic and related measures have had a significant adverse impact on many sectors of the economy, including the waste and recycling industry. The resulting business closures, increases in unemployment and loss of consumer financial stability and confidence resulted in waste and recycling volume declines and reductions in customers’ waste service needs, which adversely affected our business as well as those of our customers and others within the waste and recycling industry.

Our business and the waste and recycling industry have been adversely, and may be materially adversely affected, by the COVID-19 pandemic and the global response. Primarily due to the impact of COVID-19, a number of our customers either closed operations for a period of time and/or reduced operations or on-site work, particularly those in the restaurant and foodservice industries, resulting in the production of less waste and recyclable materials and, consequently, less demand for waste brokerage services. Several of our customers ultimately declared bankruptcy due to the impact of the pandemic. Additionally, within the waste and recycling industry, during the early stages of the pandemic, there was a decrease in the availability of haulers and other industry participants, primarily due to labor shortages. We also incurred some costs related to health, safety and financial security of our workforce during the COVID-19 pandemic, including increased automation in connection with transitioning our workforce to work-from-home. Costs increased for others within the waste and recycling industry as well, in part due to increased vendor costs particularly with respect to owners and operators of landfills and hauling services, many of which guaranteed full-time hourly employees compensation for a 40-hour work week regardless of any service decreases or reduced work schedules. It could be necessary for us and others within the waste and recycling industry to incur additional such costs in the future related to pandemic conditions or in connection with transitioning back to an in-office work environment.

We received $10.8 million in loans under the U.S. federal government’s Paycheck Protection Program established under the CARES Act. The receipt and any forgiveness of these loans was dependent on us having initially qualified for the loans and qualifying for forgiveness based on the funds being used for certain expenditures such as payroll costs and rent. We initially elected to repay $2.3 million of the loans during the year ended December 31, 2020, but the full $10.8 million amount of the loans was forgiven in March and June 2021. The SBA and other government communications have however indicated that all loans in excess of $2.0 million will be subject to audit and that those audits could take up to seven years to complete. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” Note 5 – Contingencies and uncertainties/COVID-19 pandemic and Note 19 – Subsequent events in the notes to our audited consolidated financial statements included elsewhere in this prospectus.

A broad-based economic slowdown resulting from prolonged negative effects of COVID-19 or otherwise could have significant adverse consequences for the financial condition of our customers or suppliers. As a result, customers may seek to reduce service levels or terminate contracts, or they may be unable to timely pay outstanding receivables owed to us, each of which would adversely affect our results of operations and cash flows. Additionally, such factors have, at times, made it more challenging to negotiate, renew or expand service contracts with acceptable pricing terms. Volume changes can fluctuate dramatically by line of business and decreases in volumes in higher margin businesses, such as what we have seen with COVID-19, can impact key financial metrics. Additionally, if stay-at-home orders and work from home trends continue or are re-instated, the demand for our services from our commercial and public customers could continue to or further negatively impact us. To the extent the landfills and waste haulers experience a deterioration in financial condition or operational capability as a result of the impacts of COVID-19 or another economic slowdown, we may experience material supply chain disruptions and delays, which could also increase our operating costs. If a large portion of our employee base or our hauler base were to become ill, it could impact our ability to provide timely and reliable service. Additionally, the transition of most of our back-office employees to work-from-home increases various operational risks, including potential exposure to cyber incidents, loss of data, fraud, internal control challenges and other disruptions as a consequence of more employees accessing our systems and information remotely in the course of their ordinary work. Many within the waste and recycling industry were exposed to these same risks as well.

The COVID-19 pandemic has adversely affected many industries as well as the economies and financial markets of many countries, initially causing a significant deceleration of economic activity. This slowdown reduced production, decreased demand for a broad variety of goods and services, diminished trade levels and led to widespread corporate downsizing, causing a sharp increase in unemployment. Although many of these impacts have lessened, there are still significant global supply chain issues impacting many different industries. We have also seen significant disruption of and extreme volatility in the global capital markets, which could increase the cost of, or entirely restrict access to, capital. The long-term impact of this outbreak on the United States and world economies is uncertain and these adverse impacts could worsen, impacting all segments of the global economy, and could result in a significant recession or worse, any of which could impact our business.

Considerable uncertainty still surrounds the COVID-19 virus and the new strains identified globally as well as the extent and effectiveness of responses taken on a local, national, and global level, including the roll-out and long-term efficacy of vaccines. While we expect the pandemic and related events will have a negative effect on our business and could accelerate or magnify one or more of the risks described in “Risk Factors” or elsewhere in this prospectus, the full extent and scope of the impact on our business and industry as well as on national, regional and global markets and economies is highly uncertain and cannot be predicted. Accordingly, our ability to conduct our business in the manner and on the timelines previously done or presently planned could be adversely affected. Any of the foregoing risks, or other direct or indirect effects of the COVID-19 pandemic that are not currently foreseeable, could materially and adversely affect our business, financial condition and results of operations.

Our sales cycles can be long and unpredictable, and our sales efforts require considerable investment of time and expense. If our sales cycle lengthens or we invest substantial resources pursuing unsuccessful sales opportunities, our operating results and growth would be harmed.

We have historically incurred significant costs and experienced long sales cycles when selling to customers. The decision to adopt our modules may require the approval of multiple technical and business decision makers, including security, compliance, operations, finance and treasury, marketing, and IT. In addition, before our customers will commit to deploying our modules at scale, they often require extensive education about our modules and significant customer support time or pilot programs, engage in protracted pricing negotiations and seek to secure development resources. In addition, sales cycles for our customers are inherently complex and unpredictable. These complex and resource intensive sales efforts could place additional strain on our development and engineering resources. Further, even after our customers contract to use our platform, they may require extensive integration or deployment resources from us before they become active customers, which has at times extended to multiple quarterly periods following the execution of the agreement. Finally, our customers may choose to develop their own solutions that do not include any or all of our modules. They also may demand reductions in pricing as their usage of our modules increases, which could have an adverse impact on our gross margin. If we are unable to increase the revenue that we derive from these customers, then our business, results of operations and financial condition may be adversely affected.

Subject to our obligations under the Term Loan, our management team will have broad discretion over the use of the net proceeds from our sale of shares of Class A Common Stock pursuant to the SEPA, if any, and you may not agree with how we use the proceeds and the proceeds may not be invested successfully.

Subject to our obligations under the Term Loan, our management team will have broad discretion as to the use of the net proceeds from our sale of shares of Class A Common Stock pursuant to the SEPA, if any, and we could use such proceeds for purposes other than those currently contemplated. Accordingly, you will be relying on the judgment of our management team with regard to the use of those net proceeds, and you will not have the opportunity to vote on or otherwise determine how or whether the proceeds are being used appropriately. It is possible that, pending their use, we may invest those net proceeds in a way that does not yield a favorable, or any, return for us. The failure of our management team to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flows.

We may have environmental liabilities that are not covered by our insurance, regardless of whether we are at fault.

We may incur environmental liabilities arising from our operations or third parties with whom we do business. Even if we obtain legally enforceable representations, warranties and indemnities from the parties with whom we do business, these protections may not fully cover the liabilities or these parties may not have sufficient funds to perform their obligations. Some environmental laws and regulations may impose strict, joint and several liability in connection with releases of regulated substances into the environment, and can impose liability on parties who were not to blame. New or increased regulation of substances, such as PFAS or other emerging contaminants, could also lead to increased or previously unauthorized remediation costs or litigation risk. Therefore, in some situations we could be exposed to liability as a result of our conduct that was lawful at the time it occurred or the conduct of, or conditions caused by, third parties for which we are not at fault. Further, we maintain insurance with respect to these environmental liabilities, but in certain cases we have determined to do so with high deductibles. If we were to incur substantial liability for environmental damage, our insurance coverage may be inadequate to cover such liability. Also, due to the variable condition of the insurance market, we have experienced, and may experience in the future, increased insurance retention levels and increased premiums or unavailability of insurance. As we assume more risk for insurance through higher retention levels, we may experience more variability in our insurance reserves and expense. If we were to incur liability for environmental damage, environmental clean-ups, corrective action or damage not covered by insurance or in excess of the amount of our coverage, our business, financial condition and results of operations could be adversely affected.

Our customers and the third parties with whom we contract, including waste haulers, are participants in the waste and recycling industry and are therefore subject to a number of unique risks specific to this industry, which directly or indirectly subjects our business to many of the same risks to which their respective operations are subject.

We participate within the waste and recycling industry by providing consulting and management services to our customers for waste removal, waste management, logistics, and recycling solutions. Many of our customers and each of the parties with whom we contract on behalf of our customers, including waste haulers, operate within the waste and recycling industry, some of which may also construct, own and operate landfills, recycling facilities and transfer stations, and own or lease and operate collection and transfer trucks and other equipment used for collection, transfer and disposal of waste. As a result, our future financial performance and success is dependent in large part upon the viability of the waste and recycling industry and the success and survival of industry participants. However, waste and recycling industry participants and their operations are subject to a number of unique risks, including:

If any of the foregoing risks or other risks adversely affects those in the waste and recycling industry, including the waste haulers and landfill operators with whom we contract, it could cause them to raise the prices that they charge us and our customers. Any reduction in the demand for their services could also cause certain haulers and operators to consider offering services and solutions similar to ours, increasing our direct competition. Further, any events that impact the viability of their business as presently conducted or proposed to be conducted in the future or reduce the number of waste and recycling facilities or haulers could have an adverse effect on the demand for certain of our services or increase the cost thereof. Therefore, any of the foregoing risks or others that adversely affect participants in the waste and recycling industry could similarly have an adverse effect on our business, financial condition and results of operations.

Demand for our solutions is subject to volatility in our accounts’ and our haulers’ underlying businesses.

Our sales are based on accounts’ demand for solutions to manage waste and recycling needs. This sector periodically experiences economic declines and may be exacerbated by other economic, environmental and social factors. If participants in this sector reduce spending or allocate future funding in a manner that results in fewer projects, then our accounts’ underlying business may be impacted and demand for our solutions may decrease or our rate of contract renewals may decrease. A prolonged decrease in such spending may harm our results of operations. Our accounts may request discounts or extended payment terms on new arrangements or seek to extend payment terms on existing arrangements due to lower levels of infrastructure spending or for other reasons, all of which may reduce revenue. For example, during the COVID-19 pandemic, a number of our customers in the restaurant and foodservice industries ceased or significantly scaled back operations, adversely affecting our results. We may not be able to adjust our operating expenses to offset such discounts or other arrangements because a substantial portion of our operating expenses relate to personnel, facilities, and marketing programs. The level of personnel and related expenses may not be able to be adjusted quickly and is based, in significant part, on our expectations for future revenues and demand.

Our sales are also premised on the availability of haulers to transport our accounts’ waste and recyclable materials. If there is volatility within the waste and recycling industry or decreased availability of adequate haulers or other necessary vendors we may not be able to meet our customers’ needs, which would adversely affect our business. Any increase in hauler or vendor costs may also adversely affect our margins or may require us to offset such expenses or to pass these increased expenses on to our customers which may further negatively impact our relationship with our accounts and demand for our solutions.

Demand for our solutions can be affected by changes in recyclable commodity prices and quantities.

Certain of our customers collect and process, purchase or sell recyclable materials such as paper, cardboard, plastics, aluminum and other metals, and utilize our solutions and services in connection with these activities. The sale prices of and the demand for recyclable commodities are frequently volatile and when they decline, demand for our solutions will be affected. The market demand for recyclable commodities is volatile due to changes in economic conditions and numerous other factors beyond our and our customers’ control. The value of plastics is influenced by the volatility of crude oil prices, and in 2020 there was a resulting decline in the value of plastic recyclables associated with the precipitous drop in the value of crude at the onset of the COVID-19 pandemic. The value of paper products is often influenced by quality concerns, which have resulted in the imposition of restrictions by other countries, including China, on the import of certain recyclables. For instance, in 2017 the Chinese government imposed strict limits on the import of recyclable materials, including by restricting the amount of contaminants allowed in imported recycled paper. These limitations significantly decreased the global demand for recyclable commodities and resulted in lower commodity prices. The war in Ukraine may also adversely affect the commodities markets, including trading prices and volatility. Additionally, future regulation, tariffs, international trade policies or initiatives may result in further reduced demand. Any decrease in recyclable commodity prices or other facts which cause the profitability of recycling operations to decline could adversely affect demand for our solutions and have an adverse effect on our business, financial condition and results of operations.

Our Charter provides, subject to limited exceptions, that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for certain stockholder litigation matters, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders.

Our Charter provides that, unless Rubicon selects or consents in writing to the selection of an alternative forum, to the fullest extent permitted by applicable law: (a) the sole and exclusive forum for any complaint asserting any internal corporate claims, to the fullest extent permitted by law, and subject to applicable jurisdictional requirements, shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have, or declines to accept, jurisdiction, another state court or a federal court located within the State of Delaware); and (b) the sole and exclusive forum for any complaint asserting a cause of action arising under the Securities Act, to the fullest extent permitted by law, shall be the federal district courts of the United States of America. For purposes of the foregoing, “internal corporate claims” means claims, including claims in the right of Rubicon that are based upon a violation of a duty by a current or former director, officer, employee or stockholder in such capacity, or as to which Delaware General Corporation Law (the “DGCL”) confers jurisdiction upon the Court of Chancery. Any person or entity purchasing or otherwise acquiring any interest in any shares of Class A Common Stock or Class V Common Stock will be deemed to have notice of and consented to the provisions of this provision.

This choice of forum provision may limit a Rubicon stockholder’s ability to bring a claim in a forum that it finds favorable for disputes with us or any of our directors, officers or employees, which may discourage lawsuits with respect to such claims. There is uncertainty as to whether a court would enforce this provision. If a court ruled the choice of forum provision was inapplicable or unenforceable in an action, Rubicon may incur additional costs to resolve such action in other jurisdictions. The choice of forum provision is intended to apply to the fullest extent permitted by law to the above-specified types of actions and proceedings, and is intended to require, in each case, to the fullest extent permitted by law, that (i) any claims arising under the Securities Act be brought in the federal district courts of the United States in accordance with clause (b) of the choice of forum provision, and (ii) any derivative actions, including those brought to enforce any duty or liability created by the Exchange Act be brought in the United States District Court for the District of Delaware in accordance with clause (a) of the choice of forum provision. The provision does not apply to any direct claims brought by Rubicon’s stockholders on their own behalf, or on behalf of any class of similarly situated stockholders, under the Exchange Act. Rubicon stockholders will not be deemed, by operation of the choice of forum provision, to have waived Rubicon’s obligation to comply with all applicable federal securities laws and the rules and regulations thereunder.

Our Cybersecurity and Technology Related Risks

If we fail to continue to improve and enhance the functionality, performance, reliability, design, security, or scalability of our platform in a manner that responds to our customers’ evolving needs, our business may be adversely affected.

The on-demand commerce and digital ordering markets are characterized by rapid technological change, frequent new product and service introductions, and evolving industry standards. Our success has been based on our ability to identify and anticipate the needs of our customers and design and maintain a platform that provides them with the tools they need to operate their businesses in a manner that is productive and meets or exceeds their expectations. Our ability to attract new customers, retain revenue from existing customers, and increase sales to both new and existing customers will depend in large part on our ability to continue to improve and enhance the functionality, performance, reliability, design, security, and scalability of our platform. Additionally, to achieve and maintain market acceptance for our platform, we must effectively integrate with new or existing solutions that meet changing customer demands in a timely manner.

As we expand our platform and services, and as the number of our customers with higher volume sales increases, we expect that we will need to offer increased functionality, scalability and support, including to keep our platform, systems, and services secure, which requires us to devote additional resources to such efforts. To the extent we are not able to enhance our platform’s functionality in order to maintain its utility and security, enhance our platform’s scalability in order to maintain its performance and availability, or improve our support functions in order to meet increased customer service demands, our business, operating results, and financial condition could be adversely affected.

The success of enhancements, new features and services depends on several factors, including the timely completion, introduction and market acceptance of the feature, service or enhancement by customers, as well as our ability to seamlessly integrate all of our product and service offerings and develop adequate selling capabilities in new markets. We may make significant investments in new modules or enhancements that may not achieve expected returns. The continual improvement and enhancement of our platform requires significant investment and we may not have the resources to make such investment. Our improvements and enhancements may not result in our ability to recoup our investments in a timely manner, or at all. The improvement and enhancement of the functionality, performance, reliability, design, security, and scalability of our platform is expensive and complex, and to the extent we are not able to perform it in a manner that responds to our customers’ evolving needs, our business, operating results, and financial condition will be adversely affected.

Quality problems, defects, errors, failures, or vulnerabilities in our solutions or services could harm our reputation and adversely affect our business, financial condition, results of operations, and prospects.

Our solutions are, in some cases, highly complex and incorporate advanced technologies that we attempt to make interoperable with the products of other providers. Despite testing prior to release, our solutions may contain undetected defects or errors. Further, the combined use of our solutions with those of other providers may cause errors or failures, or it may expose undetected defects, errors, or failures in our solutions. These defects, errors, or failures could affect performance of the solutions and damage the businesses of our accounts, as well as delay the development or release of new offerings or new versions of solutions. Allegations of unsatisfactory performance in any of these situations could damage our reputation in the market and our relationships with our accounts, cause us to lose revenue or market share, increase our service costs, cause us to incur substantial costs in analyzing, correcting, or redesigning the solutions, cause us to lose accounts, subject us to liability for damages, and divert our resources from other tasks, any one of which could adversely affect our business, financial condition, results of operations, and prospects. We may also be required to provide full replacements or refunds for such defective product. We cannot assure you that such remediation would not harm our business, financial condition, results of operations, and prospects.

If our security measures or those of our third-party cloud data hosts, cloud computing platform providers, or third-party service partners, are breached and unauthorized access is obtained to an account’s data, our data or our IT systems our services may be perceived as not being secure, accounts may curtail or stop using our services, and we may incur significant legal and financial exposure and liabilities.

As we digitize and use cloud and web-based technologies to leverage account data to deliver a more complete account experience, we are exposed to increased security risks and the potential for unauthorized access to, or improper use of, our and our accounts’ information. Certain of our services involve the storage and transmission of accounts’ proprietary information, and security breaches could expose us to a risk of loss of this information, litigation, and possible liability. Although we devote resources to maintaining our security and integrity, we may not prevent security incidents.

The risk of a security breach or disruption, particularly through cyber-attack or cyber intrusion, including by computer hackers, foreign governments, and cyber terrorists, has increased as the number, intensity, and sophistication of attempted attacks and intrusions from around the world have increased. These threats, some of which we have experienced, include but are not limited to identity theft, unauthorized access, domain name system attacks, wireless network attacks, viruses and worms, ransomware attacks, advanced persistent threat, application centric attacks, peer-to-peer attacks, phishing, backdoor trojans, and distributed denial of service attacks. Any of the foregoing could attack our accounts’ data (including their employees’ personal data), our data (including colleagues’ personal data), or our IT systems. It is virtually impossible for us to entirely eliminate this risk. Like all solutions, our products are vulnerable to cyber-attacks. For example, in April 2021 we discovered a ransomware event in which an unauthorized third party gained access to our network. Although the April 2021 incident was fully remediated and no incidents to date of which we have knowledge have had a material impact on our business, financial condition or results of operations, the impact of cyber-attacks could disrupt the proper functioning of our solutions or services, cause errors in the output of our accounts’ work, allow unauthorized access to sensitive, proprietary, or confidential information of ours or our accounts, and other destructive outcomes.

Additionally, third parties may attempt to fraudulently induce colleagues or accounts into disclosing sensitive information such as usernames, passwords, or other information in order to gain access to our accounts’ data, our data, or our IT systems. Malicious third parties may also conduct attacks designed to temporarily deny accounts access to our services. Any security breach could result in a loss of confidence in the security of our products and services, damage our reputation, negatively impact our future sales, disrupt our business, and lead to regulatory inquiry and legal liability.

Material portions of our business require the Internet infrastructure to be reliable.

Part of our future success continues to depend on the use of the Internet as a means to perform transactions electronically, including, for example, document digitization. This in part requires ongoing maintenance of the Internet infrastructure, especially to prevent interruptions in service, as well as additional development of that infrastructure. This requires a reliable network backbone with the necessary speed, data capacity, security, and timely development of complementary products for providing reliable Internet access and services. If this infrastructure fails to be sufficiently developed or be adequately maintained, our business would be harmed because users may not be able to access our portals.

Our General Business Risks

The success of our business depends, in part, on our ability to execute on our acquisition strategy.

A portion of our historical growth has occurred through acquisitions, and we anticipate continued growth through acquisitions in the future. We are presently evaluating, and we expect to continue to evaluate on an ongoing basis, a variety of possible acquisition transactions. We cannot predict the timing of any contemplated transactions, and there can be no assurances that we will identify suitable acquisition opportunities or, if we do identify such opportunities, that any transaction can be consummated on terms acceptable to us. A significant change in our business or the economy, an unexpected decrease in our cash flows or any restrictions imposed by our debt may limit our ability to obtain the necessary capital for acquisitions or otherwise impede our ability to complete an acquisition. Certain proposed acquisitions or dispositions may also trigger a review by the U.S. Department of Justice, or “DOJ”, and the U.S. Federal Trade Commission, or “FTC”, under their respective regulatory authority, focusing on the effects on competition, including the size or structure of the relevant markets and the pro-competitive benefits of the transaction. Any delay, prohibition or modification required by regulatory authorities could adversely affect the terms of a proposed acquisition or could require us to modify or abandon an otherwise attractive acquisition opportunity. The failure to identify suitable transaction partners and to consummate transactions on acceptable terms could have a material adverse effect on our business, financial condition and results of operations.

Acquisitions also involve risks that the businesses acquired will not perform as expected, that our judgments concerning the value, strengths and weaknesses of acquired businesses will prove wrong or that we will incur unanticipated costs as a result of a transaction. We may become liable for certain unforeseen pre-acquisition liabilities of an acquired business, including, among others, tax liabilities, environmental liabilities, contingent consideration and liabilities for employment practices. In addition, an acquisition could result in the impairment of client relationships and other acquired assets such as goodwill. We may also incur costs and experience inefficiencies to the extent an acquisition expands the services, markets or geographies in which we operate due to our limited exposure and experience. Acquisitions can also involve post-transaction disputes regarding a number of matters, including a purchase price or working capital adjustment, earn-out or other contingent payments, environmental liabilities, and indemnification or other obligations. Acquisitions also place significant demands on our management’s time, which may divert their attention from our day-to-day business operations, and may lead to significant due diligence and other expenses regardless of whether we pursue or consummate any acquisition. We may also not be able to manage our growth through acquisitions due to the number and the diversity of the businesses we have acquired or for other reasons. Acquisitions may require that we incur additional debt to finance the transaction, which could be substantial and limit our operating flexibility or, alternatively, acquisitions may require that we issue stock as consideration, which could dilute share ownership. If any of these risks were to occur, our business, financial condition and results of operations may be adversely affected.

Any inability to successfully integrate our recent or future acquisitions, or realize their anticipated benefits, could have a material adverse effect on us.

Acquisitions have required, and in the future will require, that we integrate into our existing operations separate companies that historically operated independently or as part of another, larger organization, and had different systems, processes and cultures. Risks involved with the successful integration of an acquired business include, but are not limited to:

We may not be able to successfully integrate any business we have acquired or may acquire, or may not be able to do so in a timely, efficient or cost-effective manner. Our inability to effectively complete the integration of new businesses on schedule and in an orderly manner could increase costs and lower profits. Our inability to manage our growth through acquisitions, including the integration process, and to realize the anticipated benefits of an acquisition could have a material adverse effect on our business, financial condition and results of operations.

A large percentage of our revenue is tied to a small number of customers, such that the loss of any of these customers could materially and adversely affect our business, results of operations and financial condition.

We derive a significant portion of our revenues from two customers. For the years ended December 31, 2021 and 2020, we derived approximately 30% and 28%, respectively, of our total revenues from these customers. For the nine months ended September 30, 2022 and 2021, we derived approximately 27% and 29%, respectively, of our total revenues from these customers. We cannot assure you that these customers will continue to contract with us on terms or at rates currently in effect, or will not elect to contract with our competitors or attempt to perform the services we provide themselves. Further, as of September 30, 2022, December 31, 2021 and 2020, approximately 22%, 23% and 23%, respectively, of our aggregate accounts receivable and contract assets were due from these two customers. The contract term with these two customers ranges from 2 to 3 years, but one of the customers has the right to terminate without penalty with 60 days advance written notice. These contracts do not include any minimum purchase requirements for the customers and were made in the ordinary course of business. As a result, these customers could stop purchasing our services, reduce their purchase levels or request reduced pricing structures at any time. We may therefore need to adapt our pricing and marketing strategies in response to a customer who may seek concessions in return for its continued or increased business. In addition, a macroeconomic downturn or any other cause of consolidation in our industry or among our other customers could significantly increase the market share and bargaining power of a limited number of customers and give them significant additional leverage to negotiate more favorable terms and place greater demands on us. The loss of either of these customers, if not offset by revenues from new or other existing customers, or any inability of either customer to pay amounts as and when due, could adversely affect our business, financial condition and results of operations.

Our business depends on customers using our platform, and any loss of customers or decline in their use of our platform could materially and adversely affect our business, results of operations, and financial condition.

Our ability to grow and generate incremental revenue depends, in part, on our ability to maintain and grow our relationships with existing customers, to have them increase their deployment and use of our platform, and to increase or maintain transaction volume on our platform. Although our customers generally have multi-year contracts with us, they can typically terminate the agreement without penalty by providing as little as 30 days written notice and may elect not to renew the agreement following the expiration date. In addition, if our customers do not increase their use of our platform or adopt and deploy additional modules, then our revenue may decline and our results of operations may be harmed. Customers may not renew their contracts with us or reduce their use of our platform for any number of reasons, including if they are not satisfied with our platform or modules, the value proposition of our platform or our ability to meet their needs and expectations, security or platform reliability issues, or if they decide to build their own solution internally. Additionally, consumers may change their purchasing habits or reduce their orders from our current customers, which could harm their business and reduce their use of our platform. We cannot accurately predict our customers’ usage levels and the loss of customers or their usage levels of our modules may each have a negative impact on our business, results of operations, and financial condition and may cause our expansion rate to decline. If a significant number of customers cease using or reduce their usage of our platform, then we may be required to spend significantly more on sales and marketing than we currently plan to spend in order to maintain or increase revenue from our customers. Such additional sales and marketing expenditures could adversely affect our business, results of operations, and financial condition.

Clients may elect to terminate our contracts and manage operations internally.

It is possible that our clients may elect to not renew contracts for our solutions. Alternatively, clients may elect to drop maintenance on certain modules that they ultimately decide not to use. This could adversely affect our revenues and profits. Additionally, they may inadvertently allow our intellectual property or other information to fall into the hands of third parties, including our competitors, which could adversely affect our business.

Selling products and services into the public sector poses unique challenges.

We derive a portion of our revenue from sales of software-as-a-service and professional services to state, county, and city governments, other federal or municipal agencies, and other public entities. We expect that sales to public sector clients will continue to account for a portion of our revenue in the future. We face many risks and challenges associated with contracting with governmental entities, including:

Each of these risks is outside our control. If we fail to adequately adapt to these risks and uncertainties, our financial performance could be adversely affected.

If we fail to attract and retain qualified management and skilled technical personnel, our business may be adversely affected.

Our long-term success depends, in significant part, upon the continued service and performance of our senior management and other key personnel. We rely on knowledgeable, experienced and skilled technical personnel, particularly analysts, product developers and service personnel to provide our services, often in a stringent regulatory environment. Certain of our employees, including our senior management and the key employees of the various businesses we have acquired, have exceptionally strong knowledge of our businesses, sectors and clients. Their departure could lead to the loss of know-how and information of value to us, and their departure could pose a risk to key client relationships. Our continued growth will also depend upon our ability to attract and retain additional skilled management and other key employees, including in new markets, whether organically or through acquisitions. For certain positions, there may be a limited number of qualified people to fulfill the roles, whether limited based on scarcity with respect to the particular skillset, within a given geography or otherwise. The loss of the services of one or more members of our management team or of qualified employees and other key personnel, or the inability to identify, hire and retain the key personnel that may be necessary to grow our business, could have a material adverse effect on our business, financial condition and results of operations.

Our international operations subject us to additional risks that could adversely affect our business.

We have activities outside of the United States and work with some international third-party providers, including product developers in Europe. Our operations, those of the third parties with which we work as well as those of our customers, are therefore subject to regulatory, economic, political and other events and uncertainties in countries where these operations are located. Further, our growth strategy includes expansion into additional international markets. In addition to the risks discussed elsewhere herein that are common to both our domestic and international operations, we face risks specific to our foreign activities, including but not limited to:

Foreign operations bring increased complexity and the costs of managing or overseeing foreign operations, including adapting and localizing services or systems to specific regions and countries, can be material. Further, international operations carry inherent uncertainties regarding the effect of local or domestic actions, such as the unpredictable impact of the referendum vote in the United Kingdom to leave the European Union (Brexit) and the uncertainty regarding the terms that govern its exit, any of which could be material. These and other risks related to our foreign operations, or the associated costs or liabilities, could have a material adverse effect on our business, financial condition and results of operations.

We may be unable to protect our proprietary rights.

Many of our product and service offerings incorporate proprietary information, trade secrets, know-how, and other intellectual property rights. We rely on a combination of contracts, patents, copyrights, and trade secret laws to establish and protect our proprietary rights in our technology. We cannot be certain that we have taken all appropriate steps to deter misappropriation of our intellectual property. There has also been an apparent evolution in the legal standards and regulations courts and the U.S. patent office may apply in favorably evaluating software patent rights. We are not currently involved in any material intellectual property litigation; however, we may be a party to such litigation in the future to protect our proprietary information, trade secrets, know-how, and other intellectual property rights. We cannot assure you that third parties will not assert infringement or misappropriation claims against us with respect to current or future products. Any claims or litigation, with or without merit, could be time-consuming, costly, and a diversion to management. Any such claims and litigation could also cause delays or require us to enter into royalty or licensing arrangements. Such royalty or licensing arrangements, if required, may not be available on terms acceptable to us, if at all. Therefore, litigation to defend and enforce our intellectual property rights could have a material adverse effect on our business, regardless of the final outcome of such litigation.

We rely on software licensed from, and services rendered by, third parties in order to provide our modules and run our business.

We rely on software licensed from, and services rendered by, third parties in order to provide our modules and run our business. Third-party software and services may not continue to be available on commercially reasonable terms, or at all. Any loss of the right to use, or any failures of, third-party software or services could result in delays in our ability to provide our modules or run our business until equivalent software or services are developed by us or, if available, identified, obtained and integrated, which could be costly and time-consuming and may not result in an equivalent module, any of which could cause an adverse effect on our business and operating results. Further, customers could assert claims against us in connection with such service disruption or cease conducting business with us altogether. Even if not successful, a claim brought against us by any of our customers would likely be time-consuming and costly to defend and could seriously damage our reputation and brand, making it harder for us to sell our modules.

Pending or future litigation or governmental proceedings could result in material adverse consequences, including judgments or settlements.

As a large company with international operations, across the U.S. and Canada in particular, we are, and from time to time become, involved in lawsuits, regulatory inquiries, and governmental and other legal proceedings arising out of the ordinary course of our business, including with respect to alleged infringement of third-party patents and other intellectual property rights, commercial, corporate and securities, labor and employment, wage and hour and other claims. Additionally, our participation in the waste and recycling industry, even though we are only an indirect market participant that does not own or operate any landfill or hauling operations, subjects us to additional claims that many other companies in other industries are not likely to face. Many of these matters raise complicated factual and legal issues and are subject to uncertainties and complexities, all of which make the matters costly and often divert management’s attention from day-to-day operations. For example, we may incur costs to defend against litigation brought by government agencies and private parties who allege we are in violation of our permits and applicable environmental laws and regulations, or who assert claims alleging nuisance, environmental damage, personal injury or property damage. Additionally, in recent years, wage and employment laws have changed regularly and become increasingly complex, which has fostered litigation, including purported class actions. The timing of the final resolutions to lawsuits, regulatory inquiries, and governmental and other legal proceedings is uncertain. We may be required to pay fines or judgments, which could be significant, or to implement corrective measures, or we may have our permits and licenses modified or revoked as a result of these actions. We establish accruals for our estimates of the costs associated with lawsuits, regulatory, governmental and other legal proceedings. We could underestimate such accruals. Such shortfalls could result in significant unanticipated charges to income. A significant judgment against us, the loss of a significant permit or license, or the imposition of a significant fine or other expenses in excess of any accrual or reserve could have a material adverse effect on our business, financial condition and results of operations. See Note 16 – Commitments and contingencies in our audited consolidated financial statements included elsewhere in this prospectus.

Risks Related to Our Indebtedness

Our current liquidity, including negative cash flows and a lack of existing financial resources, raises substantial doubt about our ability to continue as a going concern, which may materially and adversely affect our business, financial condition, results of operations and prospects.

Pursuant to ASC 205, Presentation of Financial Statements, we are required to and do evaluate at each annual and interim financial statement period whether there are conditions or events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. Based on the definitions in the relevant accounting standards and our history of operating losses and negative cash flows, we currently project that we will not have sufficient cash on hand or available liquidity under existing arrangements to meet our projected liquidity needs for the next 12 months, which raises substantial doubt about our ability to continue as a going concern.

Although we have taken, and plan to continue to take, proactive measures to enhance our liquidity position and provide additional financial flexibility, including, among other things, negotiation with respect to the New Debt Facilities and receipt of binding commitments for the Financing Commitment, there can be no assurance that these measures, including the timing and terms thereof, will be successful or sufficient. Any new financing may also lead to increased costs, increased interest rates, additional and more restrictive financial covenants and other lender protections, and whether we will be able to successfully complete any such refinancing will depend on market conditions, the negotiations with those lenders and investors, and our financial performance. The Financing Commitment and the New Debt Facilities are also proposed to include potential equity financing, the terms of which could cause substantial dilution to existing stockholders. In addition, we are formulating additional plans to extend cash availability, including modifying our operations to further reduce spending, but these steps may not produce the anticipated results or provide any benefit at all. While management believes that our plan to address the pending debt maturities is probable of being achieved, and our financial statements have accordingly been prepared assuming that we will continue as a going concern, there can be no assurance the necessary financing will be available on terms acceptable to us, or at all. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” and Note 19, Liquidity, and Note 20, Subsequent Events, in our unaudited condensed consolidated financial statements included elsewhere in this prospectus.

If we are unable to obtain adequate additional capital resources to fund our liquidity needs, we will not be able to continue to operate our business pursuant to our current business plan, which would require us to further modify our operations to reduce spending to a sustainable level by, among other things, delaying, scaling back or eliminating some or all of our ongoing or planned investments in corporate infrastructure, business development, sales and marketing, product development and other activities, selling certain business lines or assets or we may be forced to discontinue our operations entirely and/or liquidate our assets, in which case it is likely that equity investors would lose most or all of their investment. The substantial doubt about our ability to continue as a going concern may also affect the price of our common stock and our credit rating, negatively impact relationships with third parties with whom we do business, including customers, vendors, lenders and employees, prevent us from identifying, hiring or retaining the key personnel that may be necessary to operate and grow our business and limit our ability to raise additional capital. Any of the foregoing factors could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our substantial levels of indebtedness could adversely affect our business.

As of September 30, 2022, we had approximately $99.6 million of indebtedness, consisting of $69.5 million in borrowings under our term loan (including a subordinated term loan in the amount of $20.0 million) and $30.1 million under our revolving credit facility. As of December 31, 2021, we had approximately $103.6 million of indebtedness, consisting of $73.7 million in borrowings under our term loan (including a subordinated term loan in the amount of $20.0 million) and $29.9 million under our revolving credit facility. Our indebtedness could have important consequences for us and our investors, including, but not limited to:

In addition, as our indebtedness matures, or if we are unable to service our high level of indebtedness, we may need to restructure or refinance all or a portion of our indebtedness, sell material assets or operations or raise additional debt or equity capital. We may not be able to effect any of these actions on a timely basis, on commercially reasonable terms, or at all, and these actions may not be sufficient to meet our capital requirements. Furthermore, we may not be able to invest in our business and as a result, we may not be able to achieve our forecasted results of operations.

The interest rates under our existing indebtedness are significant – LIBOR plus 9.5% for our term loan, 15.0% for our subordinated term loan and SOFR plus 5.6% for our revolving credit facility bears interest. Our ability to make payments on debt (including interest), to repay existing or future indebtedness when due, to fund operations and significant planned capital expenditures and to support our growth strategy will depend on our ability to generate cash in the future. Our ability to produce cash from operations is, and will be, subject to a number of risks, including those described above in “—Risks Related to Our Business and Industry” and elsewhere in this prospectus. Our ability to repay debt will also depend on external factors that are outside of our control, including economic, financial, competitive, legislative, regulatory and other factors. If we are unable to make required interest and principal payments on our indebtedness, it would result in an event of default under the agreements governing such indebtedness, which may result in the acceleration of some or all of our outstanding indebtedness and foreclosure on the assets that secure such indebtedness.

Although our debt agreements contain restrictions on the incurrence of additional indebtedness, the amount of indebtedness that could be incurred in the future in compliance with these restrictions could be substantial, thereby exacerbating the risks associated with our high level of indebtedness. For example, under our credit facility, we may borrow up to $20.0 million in the form of a term loan and, subject to outstanding letters of credit, up to $60.0 million under our revolving credit facility.

Any of the foregoing risks could adversely affect our business, financial condition and results of operations. For additional information on our indebtedness, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Liquidity and Capital Resources” and Note 19, Liquidity, and Note 20, Subsequent Events, in our unaudited condensed consolidated financial statements included elsewhere in this prospectus.

The terms and covenants in our existing indebtedness restrict our ability to engage in some business and financial transactions, which could adversely affect our business.

Our credit facility has restrictive covenants that limit our and our subsidiaries’ ability to, among other things:

In addition, our credit facility contains financial maintenance covenants that, among other things, require us to maintain minimum qualified billed and unbilled receivables and to not exceed a specified borrowing base or net leverage ratio tested at the end of each quarter. Among other things, we may not be able to borrow money under our credit facility if we are unable to comply with the financial and other covenants included therein. Our credit facility also contains certain customary representations and warranties, affirmative covenants and events of default with acceleration rights (including, among other things, an event of default upon a material adverse change in our business condition (financial or otherwise), operations, properties or prospects, change of management, or change of control). If an event of default occurs, our lenders will be entitled to take various actions, including the acceleration of amounts due under our credit facility and all actions permitted to be taken by a secured creditor. Our revolving credit facility also includes a lockbox arrangement, which provides for receipts to be swept daily to reduce borrowings outstanding at the discretion of the lender. Our term loan also includes a qualified equity contributions requirement of $50.0 million during the period on or prior to June 30, 2022 and, because the Mergers did not occur prior to this date, we did not satisfy the equity contributions requirement, giving the lender the right to use our available funds under our revolving credit facility as term loan collateral.

The YA SPA contains restrictive covenants that limit our ability to, among other things:

The YA Warrant and YA Convertible Debentures also contain certain customary representations and warranties, affirmative covenants and events of default with acceleration rights (including, among other things, upon cross-defaults under other loan documents, bankruptcy or insolvency, and delisting of the Class A Common Stock). If an event of default occurs, the Yorkville Investor will be entitled to take various actions, which include the ability to (i) declare the full unpaid principal amount of the YA Convertible Debentures, together with interest and other amounts owing in respect thereof, immediately due and payable in cash and (ii) force Rubicon to purchase the YA Warrant in whole from the Yorkville Investor by paying to the Yorkville Investor a cash amount equal to the product of (a) $20.0 million, multiplied by (b) the quotient of (y) the number of YA Warrant Shares called for by the YA Warrant as of the date such payment is made divided by (z) the original number of YA Warrant Shares underlying the YA Warrant (plus any increase required pursuant to the terms thereof), which amount will be paid within 20 trading days of the date of notice from the Yorkville Investor.

Any future debt that we incur may contain additional and more restrictive negative covenants and financial maintenance covenants. These restrictions could limit our ability to obtain debt financing, repurchase stock, pay dividends, refinance or pay principal on our outstanding debt, complete acquisitions for cash or debt or react to changes in our operating environment or the economy.

Our failure to comply with our obligations or the agreements governing any future indebtedness may result in an event of default under the applicable agreement. A default, if not cured or waived, may permit acceleration of some or all of our other indebtedness and trigger other termination and similar rights under other contracts. We cannot be certain that we will be able to remedy any defaults and, if our indebtedness is accelerated, we cannot be certain that we will have sufficient funds available to pay the accelerated indebtedness or that we will have the ability to refinance the accelerated indebtedness on terms favorable to us or at all, any of which could have a material adverse effect on our business, financial condition and results of operations.

The required interest payments on our indebtedness under the credit facility may be impacted by reforms related to the London Interbank Offered Rate (“LIBOR”). The variable interest rates applicable under the credit facility are linked to LIBOR as the benchmark rate for establishing such rates. Recent national, international, and other regulatory guidance and reform proposals regarding LIBOR are requiring certain LIBOR tenors to be discontinued or become unavailable by the end of 2021 and LIBOR to be fully discontinued or become unavailable as a benchmark rate by June 2023. Although one or more of our credit facilities includes mechanics to facilitate the adoption by us and our lenders of an alternative benchmark rate for use in place of LIBOR, no assurance can be made that such alternative benchmark rate will perform in a manner similar to LIBOR or result in interest rates that are at least as favorable to us as those that would have resulted had LIBOR remained in effect, which could result in an increase in our interest expense and other debt service obligations. In addition, the overall credit market may be disrupted as a result of the replacement of LIBOR or in the anticipation thereof, which could have an adverse impact on our ability to refinance, reprice, or amend our existing indebtedness or incur additional indebtedness on favorable terms or at all.

Risks Related to Ownership of Our Securities

Certain existing shareholders purchased securities in Rubicon at a price below the current trading price of such securities, and may experience a positive rate of return based on the current trading price. Future investors in Rubicon may not experience a similar rate of return.

Certain shareholders in Rubicon, including certain Selling Securityholders, acquired and may acquire shares of Class A Common Stock (or Class B Units) or Private Warrants at prices below, in some cases considerably below, the current trading price of our Class A Common Stock or for no cash consideration at all and may experience a positive rate of return based on the current trading price.

Additionally, the Yorkville Investor acquired the Yorkville Commitment Shares for no cash consideration and may acquire additional Class A Common Stock at a discount to the current trading price in the case of any other shares of Class A Common Stock to be issued pursuant to the SEPA, YA Convertible Debentures and YA Warrant. The Insider Investors may acquire additional Class A Common Stock at a discount to the current trading price in the event that the Insider Convertible Debentures are converted to shares of Class A Common Stock. Given the relatively lower purchase prices that some of our shareholders paid to acquire securities and exercise prices that some of our shareholders may pay to exercise Private Warrants to acquire shares of Class A Common Stock compared to the current trading price of our shares of Class A Common Stock, these shareholders, some of whom are Selling Securityholders pursuant to this or other registration statements we are obligated to file to register the resale of shares of Class A Common Stock, in some instances will earn a positive rate of return on their investment, which may be a significant positive rate of return, depending on the market price of our shares of Class A Common Stock at the time that such shareholders choose to sell their shares of Class A Common Stock. Investors who purchased units in Founder SPAC’s initial public offering, who purchased Founder Class A Shares on the NYSE following the IPO or who purchase our Class A Common Stock and Public Warrants on the NYSE following the Business Combination may not experience a similar rate of return on the securities they purchase due to differences in the purchase prices and the current trading price. Based on the last reported sale price of our shares of Class A Common Stock on January 25, 2023 of $1.85 and their respective purchase prices, the Selling Securityholders may receive potential profits up to $0.99 per share. See the section titled “Summary—Information Related to Offered Securities” for additional information regarding the prices paid by and potential profits the Selling Securityholders may earn on sales of the securities registered hereunder.

Substantial future sales of shares of Class A Common Stock could cause the market price of our shares of Class A Common stock to decline.

We have agreed, at our expense, to prepare and file this and other registration statements with the SEC providing for the resale of shares of Class A Common Stock. The shares of Class A Common Stock being offered for resale in this prospectus represent approximately 12.9% of our total outstanding shares of Common Stock as of the date of this prospectus (after giving effect to the conversion of the YA Convertible Debentures into all of the YA Conversion Shares registered for resale in this prospectus).

After this registration statement and any others we file in respect of the resale of shares of Class A Common Stock become effective, and until such time that they are no longer effective, these registration statements will permit the resale of the applicable securities.

Potential new issuances of Class A Common Stock include (a) the exercise of all Warrants, (b) the vesting of all RSU and DSU awards, (c) the utilization of the SEPA, (d) conversion of the YA Convertible Debentures, (e) exercise of the YA Warrant, (f) settlement of the Deferred Fee Arrangements in stock, and (g) satisfaction of the Vellar Termination Agreement in stock:

The resale, or expected or potential resale, of a substantial number of our shares of Class A Common Stock in the public market could adversely affect the market price for our shares of Class A Common Stock and make it more difficult for you to sell your shares of Class A Common Stock at times and prices that you feel are appropriate. In particular, as a result of the SEPA, the Yorkville Investor is an “underwriter” as such term is defined in Section 2(a)(11) of Securities Act, and the SEPA contemplates that the Yorkville Investor expects to resell any shares of Class A Common Stock we may issue and sell pursuant thereto. The FPA Sellers may also resell a significant number of shares of Class A Common Stock in the market with respect to the shares that they retained pursuant to the FPA Termination Agreements and that may be issued in the future pursuant to the Vellar Termination Agreement. Furthermore, we expect that, because there will be a large number of shares registered pursuant to this and other registration statements, the applicable selling securityholders will continue to offer such covered securities for a significant period of time, the precise duration of which cannot be predicted. Accordingly, the adverse market and price pressures resulting from an offering pursuant to a registration statement may continue for an extended period of time.

In addition, because the current market price of our Class A Common Stock is higher than the price certain selling securityholders paid for their securities, there is more likelihood that selling securityholders holding shares of Class A Common Stock will sell their shares as soon as the applicable registration statement is declared effective and any applicable lock-up restrictions expire.

See the section entitled “Certain Financing Transactions” for additional information regarding the SEPA, the YA Convertible Debentures, the YA Warrant, the Forward Purchase Agreement, the FPA Termination Agreements, the Insider Convertible Debentures, and the Deferred Fee Arrangements.

The issuances of additional shares of Class A Common Stock under certain of our contracts and arrangements may result in dilution of holders of Class A Common Stock and have a negative impact on the market price of the Class A Common Stock.

Pursuant to the Vellar Termination Agreement, Rubicon may issue Vellar up to $2.0 million of shares of Class A Common Stock (“Settlement Shares”) on the earlier of May 30, 2024 or the six month anniversary of the conversion of 90% or more of the YA Convertible Debentures into shares of Class A Common Stock (the “Vellar Lock-Up Date”) or pay such obligation in cash, in each case on the terms and subject to the conditions set forth therein. The number of Settlement Shares issuable pursuant to the Vellar Termination Agreement will be determined based on the average daily VWAP of the Class A Common Stock over the ten scheduled trading days preceding such share issuance. Without giving effect to the exercise of any other potential future issuance, and assuming that (a) the full $2.0 million obligation set forth above is paid in Class A Common Stock, and (b) the VWAP at which we issue Settlement Shares is $5.00, such additional issuances would represent in the aggregate approximately 400,000 additional shares of Class A Common Stock or approximately 0.2% of the total number of shares of Common Stock outstanding as of January 25, 2023, after giving effect to only such issuance. If the 10 day VWAP price is $2.00, such additional issuances would represent in the aggregate approximately 1 million additional shares of Class A Common Stock or approximately 0.6% of the total number of shares of Common Stock outstanding as of January 25, 2023, after giving effect to only such issuance. The timing, frequency, and the price at which we issue shares of Class A Common Stock are subject to market prices and management’s decision to repay such amount in equity, if at all. Any shares of Class A Common Stock issued pursuant to the Vellar Termination Agreement will need to be registered for resale on a Form S-1 or Form S-3 (as applicable) registration statement. For more information, see “Certain Financing Transactions—FPA Termination Agreements.”

Pursuant to certain deferred fee arrangements entered into with certain of our advisors in connection with the consummation of the Business Combination, we issued 443,341, 4,373,210, and 2,485,604 shares of Class A Common Stock pursuant to the Cowen Deferred Fee Arrangement, Moelis Deferred Fee Arrangement, and Cohen Deferred Fee Arrangement, respectively, and may issue an aggregate of approximately $7.1 million of additional shares of Class A Common Stock in satisfaction of the outstanding amounts owed under a deferred fee arrangement with another financial advisor pursuant to the terms thereof (together with the Cowen Deferred Fee Arrangement, the Moelis Deferred Fee Arrangement, and the Cohen Deferred Fee Arrangement, the “Deferred Fee Arrangements”). Under the unsettled arrangement, at our election, we may pay the $7.1 million obligation in cash and/or equity within six months following the Closing (February 15, 2023). Any shares issued upon such election shall be issued at the ten trading-day VWAP prior to any such election. Without giving effect to any other potential future issuance or the issuance of the Cowen Deferred Fee Shares, Moelis Deferred Fee Shares, and Cohen Deferred Fee Shares and assuming that (a) the full $7.1 million is paid in Class A Common Stock, and (b) the VWAP at which we issue shares is $5.00, such additional issuances would represent in the aggregate approximately 1.4 million additional shares of Class A Common Stock or approximately 0.8% of the total number of shares of Common Stock outstanding as of January 25, 2023, after giving effect to only such issuance. If the 10 day VWAP price is $2.00, such additional issuances would represent in the aggregate approximately 3.5 million additional shares of Class A Common Stock or approximately 2.0% of the total number of shares of Common Stock outstanding as of January 25, 2023, after giving effect to only such issuance. The timing, frequency, and the price at which we issue shares of Class A Common Stock are subject to market prices and management’s decision to repay such amount in equity, if at all. Any shares of Class A Common Stock issued pursuant to these arrangements will need to be registered for resale on a Form S-1 registration statement.

Pursuant to the SEPA, we may issue and sell up to $200.0 million of shares of Class A Common Stock to the Yorkville Investor. The price at which we may issue and sell shares will be at 97% of the lowest daily VWAP of the Class A Common Stock during the three trading days following a notice to sell to the Yorkville Investor, provided that we are subject to certain caps on the amount of shares of Class A Common Stock that we may sell on any single day. The shares of Class A Common Stock issuable under the SEPA will be registered for resale on a different registration statement to be filed with the SEC following the effectiveness of the registration statement of which this prospectus forms a part. Without giving effect to the SEPA Exchange Cap (as defined below) or any other potential future issuance other than pursuant to the SEPA (although the Yorkville Investor may acquire and resell additional shares of Class A Common Stock pursuant to the YA Convertible Debentures and the YA Warrant, as discussed below), and assuming that (a) we issue and sell the full $200.0 million of shares of Class A Common Stock under the SEPA to the Yorkville Investor, (b) the beneficial ownership limitations set forth in the SEPA are waived, and (c) the issue price for such sales is $5.00 per share, such additional issuances would represent in the aggregate approximately 40 million additional shares of Class A Common Stock or approximately 19.0% of the total number of shares of Common Stock outstanding as of January 25, 2023, after giving effect to only such issuance. If the per share issue price is $2.00, such additional issuances would represent in the aggregate approximately 100 million additional shares of Class A Common Stock or approximately 36.9% of the total number of shares of Common Stock outstanding as of January 25, 2023, after giving effect to only such issuance. If the beneficial ownership limitations are not waived, at a $5.00 and $2.00 issue price per share of Class A Common Stock, such issuances would represent approximately 17.9 million additional shares of Class A Common Stock, or approximately 9.99% of the total number of shares of Common Stock outstanding at Closing. The timing, frequency, and the price at which we issue shares of Class A Common Stock are subject to market prices and management’s decision to sell shares of Class A Common Stock, if at all. Any shares of Class A Common Stock issued pursuant to this arrangement will need to be registered for resale on a Form S-1 registration statement. For more information, see “Certain Financing Transactions—SEPA.”

Pursuant to the YA Convertible Debentures and YA Warrant, we have agreed to issue up to $37.0 million of shares of Class A Common Stock upon the conversion of the YA Convertible Debentures or exercise of the YA Warrant, as applicable. Without giving effect to any other potential future issuance other than pursuant to the YA Convertible Debentures and YA Warrant and assuming that (a) the Second YA Convertible Debenture is issued, (b) the full amounts with respect to the conversion or exercise, as applicable, of the YA Convertible Debentures and YA Warrant are paid in Class A Common Stock (without giving effect to the interest and fees accrued thereunder), and (c) the VWAP at which we issue shares is $5.00, such issuances would represent in the aggregate approximately 7.4 million additional shares of Class A Common Stock or approximately 4.2% of the total number of shares of Common Stock outstanding as of January 25, 2023, after giving effect to only such issuances. If the VWAP price at which we issue shares is $2.00, such issuances would represent in the aggregate approximately 18.5 million additional shares of Class A Common Stock or approximately 9.8% of the total number of shares of Common Stock outstanding as of January 25, 2023, after giving effect to only such issuances. The timing, frequency, and the price at which we issue shares of Class A Common Stock are subject to market prices, management’s decision to pay such obligations in cash (if at all) and the Yorkville Investor’s decision to convert the YA Convertible Debentures into, and exercise the YA Warrant for, shares of Class A Common Stock. Any shares of Class A Common Stock issued pursuant to the YA Warrant will need to be registered for resale on a Form S-1 or Form S-3 (as applicable) registration statement. For more information, see “Certain Financing Transactions—YA Convertible Debentures” and “Certain Financing Transactions—YA Warrant.”

Pursuant to the Insider Securities Purchase Agreement, Rubicon has agreed to issue and sell to the Insider Investors Insider Convertible Debentures in the aggregate principal amount of up to $17.0 million, net of an original issuance discount of $2.0 million, which are convertible into shares of Class A Common Stock. Without giving effect to any other potential future issuance other than pursuant to the Insider Convertible Debentures and assuming that (a) the additional Insider Convertible Debentures are issued at the second closing, (b) the full amounts with respect to the conversion of the Insider Convertible Debentures are paid in Class A Common Stock (without giving effect to the interest and fees accrued thereunder), and (c) the VWAP at which we issue shares is $5.00, such issuances would represent in the aggregate approximately 3.4 million additional shares of Class A Common Stock or approximately 2.0% of the total number of shares of Common Stock outstanding as of January 25, 2023 after giving effect to only such issuances. If the VWAP price at which we issue shares is $2.00, such issuances would represent in the aggregate approximately 8.5 million additional shares of Class A Common Stock or approximately 4.7% of the total number of shares of Common Stock outstanding as of January 25, 2023, after giving effect to only such issuances. The timing, frequency, and the price at which we issue shares of Class A Common Stock are subject to market prices and the Insider Investors’ decision to convert the Insider Convertible Debentures into shares of Class A Common Stock. Any shares of Class A Common Stock issued pursuant to the Insider Convertible Debentures will need to be registered for resale on a Form S-1 or Form S-3 (as applicable) registration statement. Further, the Insider Convertible Debentures may be converted into shares of Class A Common Stock at an initial conversion price equal to the lower of 110% of: (i) the average closing price of Class A Common Stock for the five (5) trading days immediately preceding the date of the respective closing or (ii) the closing price of Class A Common Stock immediately preceding the date of the respective closing, subject to adjustments as further specified in the Insider Convertible Debentures. The Insider Convertible Debentures will be fully repayable in cash upon maturity. The Insider Securities Purchase Agreement contained customary representations, warranties, and covenants for the sale and purchase of the Insider Convertible Debentures. For more information, see “Certain Financing Transactions – Insider Convertible Debentures.” 

If and when we issue securities, such recipients, upon effectiveness of a Form S-1 or Form S-3 (as applicable) registration statement registering such securities for resale, may resell all, some or none of such shares in their discretion and at different prices subject to the terms of the applicable agreement. As a result, investors who purchase shares from such recipients at different times will likely pay different prices for those shares, and so may experience different levels of dilution (and in some cases substantial dilution) and different outcomes in their investment results. Investors may experience a decline in the value of the shares they purchase as a result of future issuances or issuances and sales made by Rubicon to such aforementioned parties or others at prices lower than the prices such investors paid for their shares. In addition, if we issue a substantial number of shares to such parties, or if investors expect that we will do so, the actual sales of shares or the mere existence of an arrangement with such parties may adversely affect the price of our securities or make it more difficult for us to sell equity or equity-related securities in the future at a desirable time and price, or at all.

The issuance, if any, of Class A Common Stock would not affect the rights or privileges of Rubicon’s existing stockholders, except that the economic and voting interests of existing stockholders would be diluted, potentially substantially. Although the number of shares of Class A Common Stock that existing stockholders own would not decrease as a result of these additional issuances, the shares of Class A Common Stock owned by existing stockholders would represent a smaller percentage of the total outstanding shares of Class A Common Stock after any such issuance, potentially significantly smaller.

See the section entitled “Certain Financing Transactions” for additional information regarding the SEPA, the Insider Convertible Debentures, the YA Convertible Debentures, the YA Warrant, the Forward Purchase Agreement, the FPA Termination Agreements, and the Deferred Fee Arrangements.

The Warrants are exercisable for Class A Common Stock, which may increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.

Rubicon has an aggregate of 30,016,851 Warrants issued and outstanding, representing the right to purchase an equivalent number of shares of Class A Common Stock in accordance with the terms of the Warrant Agreement. The exercise price of the Warrants is $11.50 per share. Without giving effect to the issuance of any shares of Class A Common Stock pursuant to the FPA Termination Agreements, the Deferred Fee Arrangements (other than the Cowen Deferred Fee Shares, the Moelis Deferred Fee Shares, and the Cohen Deferred Fee Shares), the Insider Convertible Debentures, the SEPA (other than the Yorkville Commitment Shares), the YA Convertible Debentures or the YA Warrant, assuming full exercise of all Warrants, the shares of Class A Common Stock issued upon such exercises would represent approximately 14.9% of the total number of shares of Common Stock outstanding on January 25, 2023, after giving effect to such exercises. To the extent such Warrants are exercised, additional shares of Class A Common Stock will be issued, which will result in dilution to Rubicon’s existing stockholders and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market or the fact that such Warrants may be exercised could adversely affect the market price of Class A Common Stock. However, there is no guarantee that the Warrants will ever be in the money prior to their expiration, and as such, the Warrants may expire worthless.

The Public Warrants may never be in the money, and they may expire worthless and the terms of such Public Warrants may be amended in a manner adverse to a holder if holders of at least a majority of the then-outstanding Public Warrants approve of such amendment.

The Public Warrants were issued in registered form pursuant to the Warrant Agreement. The Warrant Agreement provides that the terms of the Public Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval of the holders of at least a majority of the then-outstanding Public Warrants to make any change that adversely affects the interests of the registered holders of Public Warrants. Accordingly, we may amend the terms of the Public Warrants in a manner adverse to a holder if holders of at least a majority of the then-outstanding Public Warrants approve of such amendment. Notwithstanding the foregoing, any amendment to the terms of the Private Warrants only requires the consent of the Company and the holders of a majority of the Private Warrants.

We may redeem your unexpired Warrants prior to their exercise at a time that is disadvantageous to you, thereby making your Warrants worthless.

Rubicon may redeem outstanding Warrants prior to their exercise at a time that is disadvantageous to you, thereby significantly impairing the value of such warrants. Rubicon has the option to redeem not less than all of the outstanding Warrants at any time during the exercise period, at a price of $0.01 per Warrant, upon not less than 30 days’ prior written notice of redemption to each Warrant holder, (i) provided that the last reported sale price of the Class A Common Stock equals or exceeds $18.00 per share on each of 20 trading days within a 30 trading day period commencing after the Warrants become exercisable and ending on the third trading day prior to the notice of redemption to Warrant holders, and (ii) provided that there is an effective registration statement with respect to the Class A Common Stock underlying such Warrants, and a current prospectus relating thereto, available throughout the 30-day redemption or Rubicon has elected to require the exercise of the Warrants on a “cashless basis.”

If and when the Warrants become redeemable by Rubicon, it may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of the outstanding Warrants could force you (i) to exercise your Warrants and pay the exercise price therefor at a time when it may be disadvantageous for you to do so, (ii) to sell your Warrants at the then-current market price when you might otherwise wish to hold your Warrants, or (iii) to accept the nominal redemption price which, at the time that the outstanding Warrants are called for redemption, is likely to be substantially less than the market value of your Warrants.

The value received upon exercise of the Warrants (1) may be less than the value the holders would have received if they had exercised their Warrants at a later time where the underlying share price is higher and (2) may not compensate the holders for the value of the Warrants.

As of January 25, 2023, the last reported sale of price of the Class A Common Stock was $1.85 per share, which is below the threshold required for redemption.

In the event we elect to redeem the outstanding Warrants, we will mail notice of redemption by first class mail, postage prepaid, not less than thirty days prior to the redemption date to the registered holders of the Warrants to be redeemed at their last addresses as they appear on the registration books. Any notice mailed in such manner will be conclusively presumed to have been duly given whether or not the registered holder received such notice. If you do not exercise your Warrants prior to the redemption date, you would only receive the nominal redemption price for your Warrants upon surrender thereof.

There can be no assurance that we will continue to comply with the continued listing standards of NYSE.

Our Class A Common Stock and Public Warrants are currently listed on NYSE. If NYSE delists Rubicon’s securities for failure to meet the continued listing standards, Rubicon and its stockholders could face significant material adverse consequences including:
