TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

This prospectus is part of an automatic shelf registration statement that we filed with the Securities and Exchange Commission (the "SEC") as a "well-known seasoned issuer," as defined in Rule 405 under the Securities Act of 1933, as amended (the "Securities Act").

By using a shelf registration statement, we may sell the securities described in this prospectus from time to time and in one or more offerings and any selling stockholders to be named in a supplement to this prospectus may, from time to time, sell shares of common stock in one or more offerings. There is no limit on the aggregate amount of securities that we or any selling stockholders may offer pursuant to the registration statement of which this prospectus is a part. This prospectus describes the general manner in which we or any selling stockholders may offer the securities described in this prospectus. Each time we or any selling stockholders offer and sell securities pursuant to the registration statement, we will provide a prospectus supplement that contains specific information about the offering and the securities offered, and may also add, update or change information contained in this prospectus. If there is any inconsistency between information in this prospectus and any accompanying prospectus supplement, you should rely on the information in the most recent applicable prospectus supplement and documents incorporated by reference therein.

Neither this prospectus nor any accompanying prospectus supplement is an offer to sell these securities or is soliciting an offer to buy these securities in any jurisdiction where the offer or sale is not permitted.

Neither we nor any selling stockholder have authorized any person, including any underwriter, salesperson or broker, to provide information other than that provided in this prospectus, a prospectus supplement, any free writing prospectus that we authorize or any pricing supplement that we authorize. We have not authorized anyone to provide you with different information. We and any selling stockholders take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you.

You should assume that the information in this prospectus, a prospectus supplement, any free writing prospectus that we authorize and any pricing supplement that we authorize is accurate only as of the date on its cover page and that any information we have incorporated by reference is accurate only as of the date of such document incorporated by reference.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the information incorporated by reference in this prospectus contain "forward-looking statements" within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and the Private Securities Litigation Reform Act of 1995. Forward-looking statements are not historical in nature, but rather are predictive of PAR's future operations, financial condition, financial results, business strategies, and prospects. Forward-looking statements are generally identified by words such as "believe," "could", "would," "should," "will," "continue," "anticipate," "expect," "plan," "intend," "estimate," "future," "may," "potential," and similar expressions.

Forward-looking statements are based on management's current expectations and assumptions and are inherently uncertain. Actual results and outcomes could differ materially from those expressed in or implied by forward-looking statements, including forward-looking statements relating to and our expectations regarding:

Factors, risks, trends, and uncertainties that could cause our actual results to differ materially from those expressed in or implied by forward-looking statements include:

We undertake no obligation to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise, except as may be required under applicable securities law

You should be aware that the occurrence of any of the events discussed under the heading "Risk Factors" in any prospectus supplement and any documents incorporated by reference herein or therein could substantially harm our business, operations, financial condition, financial results and prospects, and that if any of these events occur, it could adversely affect the value of an investment in our securities. Market, industry and other data included in this prospectus or incorporated by reference herein are from or based on our own internal good faith estimates and research, and on publicly available publications, research, surveys and studies conducted by third parties, which we believe are reliable, but have not independently verified. Similarly, while we believe our internal estimates and research are reliable, we have not independently verified our internal estimates or research. While we are not aware of any misstatements regarding any market, industry or other data used by us or expressed in this prospectus or incorporated by reference herein, such information, because it has not been verified or, by its nature-market surveys, estimates, projections or similar data-is inherently subject to uncertainties, and actual results may differ materially from the assumptions and circumstances reflected in this information.

You should read this prospectus, any prospectus supplement and the information incorporated by reference herein and therein completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all forward-looking statements by these cautionary statements.

Given these uncertainties, you should not place undue reliance on forward-looking statements, which speak only as of the date they were made and are not guarantees of future performance.

USE OF PROCEEDS

Unless otherwise specified in a prospectus supplement, the net proceeds from the sale of the securities to which this prospectus relates will be used for general corporate purposes. General corporate purposes may include repayment of debt, repurchases of outstanding shares of common stock, acquisitions, investments, additions to working capital (including cash reserves), capital expenditures and advances to or investments in our subsidiaries. Net proceeds may be temporarily invested prior to use.

All of the shares of common stock offered by the selling stockholders will be sold by the selling stockholders for their respective accounts. We will not receive any of the proceeds from those sales by the selling stockholders.

DESCRIPTION OF CAPITAL STOCK

General

The following is a summary of our capital stock and provisions of our restated certificate of incorporation (the "Certificate of Incorporation"), our amended and restated bylaws (the "Bylaws"), and certain provisions of the Delaware General Corporation Law ("DGCL"). This summary does not purport to be complete and is qualified in its entirety by reference to the Certificate of Incorporation and Bylaws, which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. References in this section to "the Company," "we," "us" and "our" refer to PAR Technology Corporation and not to its subsidiaries.

Our authorized capital stock consists of 117,000,000 shares of stock, par value $0.02 per share, consisting of 116,000,000 shares of common stock and 1,000,000 shares of undesignated preferred stock.

Common Stock

As of March 24, 2026, we had 41,245,277 shares of common stock outstanding.

Holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders, including the election of directors. At any meeting of stockholders, the holders of shares having a majority of the voting power of the capital stock of the Company issued and outstanding and entitled to vote thereat shall be present or represented by proxy to constitute a quorum for the transaction of business. If a quorum is present, the affirmative vote of the majority of the votes cast on a matter, other than the election of directors, will be the act of the stockholders, unless the vote of a minimum or other number or amount is provided for such matter by applicable law, the Certificate of Incorporation, the Bylaws or the rules and regulations of any stock exchange or other regulatory body, in which case such minimum or other vote will be the required vote of stockholders on such matter. Our directors are elected by a plurality, which means that at any meeting of the Company's stockholders for the election of directors at which a quorum is present, nominees receiving a plurality of votes cast will be elected directors.

Subject to the rights, if any, of the holders of any then outstanding preferred stock, holders of our common stock are entitled to receive dividends out of any of the Company's funds legally available when, as and if declared by our board of directors. Further, subject to the rights and preferences of the preferred stock, holders of our common stock share ratably in all assets of the Company in the event of the liquidation, dissolution or winding up of the Company.

Holders of our common stock have no preemptive, conversion, subscription or other rights, and the terms of our common stock contain no redemption or sinking fund provisions. The rights, preferences, and privileges of the holders of our common stock are subject to and may be adversely affected by the rights of holders of shares of any series of preferred stock that we may designate in the future.

Preferred Stock

As of March 24, 2026, there were no shares of preferred stock outstanding.

Pursuant to the Certificate of Incorporation, our board of directors has the authority, without further action by stockholders, to issue up to 1,000,000 shares of preferred stock in one or more series and to fix the number, rights, preferences, privileges, qualifications and restrictions granted to or imposed upon the preferred stock, including dividend rights, conversion rights, voting rights, rights and terms of redemption, liquidation preference and sinking fund terms, any or all of which may be greater than the rights of the common stock.

The issuance of our preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring, or preventing a change of control or other corporate action, or make the removal of management more difficult.

Additionally, the issuance of preferred stock may have the effect of decreasing the market price of the common stock.

Except as otherwise provided by Delaware law or by any resolution adopted by our board of directors fixing the rights, preferences and privileges, the qualifications or restrictions of the preferred stock, the entire voting power of the shares of our capital stock for the election of directors and for all other purposes, as well as all other rights pertaining to shares of our capital stock vest exclusively in the common stock.

Anti-Takeover Effects of Delaware Law, the Certificate of Incorporation and the Bylaws

Certain provisions of Delaware law and the Certificate of Incorporation and Bylaws could make the acquisition of the Company more difficult. These provisions of the DGCL could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us. These provisions, summarized below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids and are designed to encourage persons seeking to acquire control of us to negotiate with our board of directors.

Stockholder meetings. Under the Certificate of Incorporation, the board of directors, or the chair of the board of directors or the president pursuant to a resolution approved by a majority of the then authorized number of directors of the Company may call special meetings of stockholders.

Requirements for advance notification of stockholder nominations and proposals. The Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors.

Action by written consent. Pursuant to the Certificate of Incorporation, any action required or permitted to be taken by the stockholders of the Company must be effected at an annual or special meeting of stockholders of the Company, and no action required to be taken or that may be taken at any annual or special meeting of stockholders of the Company may be taken without a meeting except by the unanimous written consent of all stockholders entitled to vote on such action.

Election and removal of directors. Nominations for the election of directors may be made by the board of directors or a committee appointed by the board of directors, or by any stockholder entitled to vote generally in the election of directors who complies with the procedures set forth in the Bylaws. All directors (other than those who may be elected by the holders of any then outstanding preferred stock, voting as a separate class) shall be elected for a one-year term expiring at the next annual meeting of stockholders. Each director shall serve until his or her successor is duly elected and qualified or until his or her death, resignation, or removal.

The board of directors has the exclusive right to increase or decrease the size of the board of directors, provided such number will not be less than a minimum of three (3) and more than a maximum of 15 directors. Vacancies and newly created directorships resulting from any increase in the authorized number of directors, and any vacancies on the board of directors resulting from death, resignation, disqualification, removal or other cause shall be filled by the affirmative vote of a majority of the remaining directors then in office, even if less than a quorum of the board of directors, or by a sole remaining director, and the directors so chosen shall hold office, subject to the limitations set forth in the Bylaws, until the next annual meeting and until their respective successors are elected and qualified. Subject to the rights of the holders of any then outstanding preferred stock any director may be removed from office, with or without cause, by the affirmative vote of the holders of a majority of the voting power of all shares of the Company entitled to vote generally in the election of directors, voting together as a single class. This system of electing directors may discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes replacing a majority of directors more difficult for stockholders.

Undesignated preferred stock. The authorization of undesignated preferred stock makes it possible for the board of directors, without stockholder approval, to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to obtain control of us. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of the Company.

Amendment of provisions in the Certificate of Incorporation. The affirmative vote of the holders of at least 66 2⁄3% of all of the shares of the Company entitled to vote generally in the election of directors, voting together as a single class, is required to amend the provisions of the Certificate of Incorporation relating to calling special meetings of stockholders, stockholder actions by written consent, the number and election of directors, and director liability.

Amendment of provisions in the Bylaws. The affirmative vote of 66 2⁄3% of the stockholders entitled to vote generally for the election of directors, voting together as a single class, is required to amend the provisions of the Bylaws relating to calling special meetings of stockholders, the advance notice procedures, the number, nomination, election, term, and removal of directors.

Forum Selection provisions in the Bylaws. The Bylaws provide that unless we select or consent in writing to the selection of an alternative forum, all complaints asserting any internal corporate claims, which are claims (including claims brought on the Company's behalf): (i) that are based upon a violation of a duty (including any fiduciary duty) owed by a current or former director, officer, employee, or stockholder in such capacity; or (ii) as to which the DGCL confers jurisdiction upon the Court of Chancery, shall, to the fullest extent permitted by law and subject to

applicable jurisdictional requirements, be made in the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have, or declines to accept, subject matter jurisdiction, another state court or a federal court located within the State of Delaware).

Further, unless we select or consent in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. The choice-of-forum provision in the Bylaws does not apply to suits brought to enforce any liability or duty created by the Exchange Act and stockholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

Any person or entity purchasing or otherwise acquiring or holding any interest in our common stock shall be deemed to have notice of and to have consented to the forum selection provisions described in the Bylaws.

Transfer Agent and Registrar

Computershare Trust Company, N.A. is the transfer agent and registrar for our common stock.

Listing

Our common stock is listed on the New York Stock Exchange under the symbol "PAR."

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we include in any applicable prospectus supplement or free writing prospectus, summarizes certain general terms and provisions of the debt securities that we may offer under this prospectus. When we offer to sell a particular series of debt securities, we will describe the specific terms of the series in a supplement to this prospectus. We will also indicate in the supplement to what extent the general terms and provisions described in this prospectus apply to a particular series of debt securities.

We may issue debt securities either separately, or together with, or upon the conversion or exercise of or in exchange for, other securities described in this prospectus. Debt securities may be senior, senior subordinated or subordinated obligations of ours and, unless otherwise specified in a supplement to this prospectus, the debt securities will be our direct, unsecured obligations and may be issued in one or more series.

The debt securities will be issued under an indenture between us and U.S. Bank Trust Company, National Association, as trustee. We have summarized select portions of the indenture below. The summary is not complete. The form of the indenture has been filed as an exhibit to the registration statement and you should read the indenture for provisions that may be important to you. In the summary below, we have included references to the section numbers of the indenture so that you can easily locate these provisions. Capitalized terms used in the summary and not defined herein have the meanings specified in the indenture.

When we refer to "the Company," "we," "our" and "us" in this section, we mean PAR Technology Corporation excluding, unless the context otherwise requires or as otherwise expressly stated, our subsidiaries.

General

The terms of each series of debt securities will be established by or pursuant to a resolution of our board of directors and set forth or determined in the manner provided in a resolution of our board of directors, in an officer's certificate or by a supplemental indenture. (Section 2.2) The particular terms of each series of debt securities will be described in a prospectus supplement relating to such series (including any pricing supplement or term sheet).

We can issue an unlimited amount of debt securities under the indenture that may be in one or more series with the same or various maturities, at par, at a premium, or at a discount. (Section 2.1) We will set forth in a prospectus supplement (including any pricing supplement or term sheet) relating to any series of debt securities being offered, the aggregate principal amount and the following terms of the debt securities, if applicable:

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

If we denominate the purchase price of any of the debt securities in a foreign currency or currencies or a foreign currency unit or units, or if the principal of and any premium and interest on any series of debt securities is payable in a foreign currency or currencies or a foreign currency unit or units, we will provide you with information on the restrictions, elections, general tax considerations, specific terms and other information with respect to that issue of debt securities and such foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Transfer and Exchange

Each debt security will be represented by either one or more global securities registered in the name of The Depository Trust Company (the "Depositary"), or a nominee of the Depositary (we will refer to any debt security represented by a global debt security as a "book-entry debt security"), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a "certificated debt security") as set forth in the applicable prospectus supplement. Except as set forth under the heading "Global Debt Securities and Book-Entry System" below, book-entry debt securities will not be issuable in certificated form.

Certificated Debt Securities. You may transfer or exchange certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. (Section 2.4) No service charge will be made for any transfer or exchange of certificated debt securities, but we may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection with a transfer or exchange. (Section 2.7)

You may effect the transfer of certificated debt securities and the right to receive the principal of, premium and interest on certificated debt securities only by surrendering the certificate representing those certificated debt securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

Global Debt Securities and Book-Entry System. Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the Depositary, and registered in the name of the Depositary or a nominee of the Depositary.

We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of debt securities.

No Protection in the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions that may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) that could adversely affect holders of debt securities.

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to any person (a "successor person") unless:

Notwithstanding the above, any of our subsidiaries may consolidate with, merge into or transfer all or part of its properties to us. (Section 5.1)

Events of Default

"Event of Default" means with respect to any series of debt securities, any of the following, unless we state in the applicable prospectus supplement that the debt securities of a series will not have the benefit of any of the following:

indenture solely for the benefit of a series of debt securities other than that series), which default continues uncured for a period of 90 days after we receive written notice from the trustee or we and the trustee receive written notice from the holders of at least 25% in principal amount of the outstanding debt securities of that series as provided in the indenture;

No Event of Default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an Event of Default with respect to any other series of debt securities. (Section 6.1) The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiaries outstanding from time to time.

We will provide the trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action we are taking or propose to take in respect thereof. (Section 6.1)

If an Event of Default with respect to debt securities of any series at the time outstanding occurs and is continuing (except as to certain events of bankruptcy, insolvency or reorganization), then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture. (Section 6.2) We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The indenture provides that the trustee may refuse to perform any duty or exercise any of its rights or powers under the indenture unless the trustee receives indemnity satisfactory to it against the costs, expenses and liabilities that might be incurred by it in performing such duty or exercising such right or power. (Section 7.1(e)) Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series. (Section 6.12)

No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment. (Section 6.8)

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. (Section 4.3) If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall mail to each securityholder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities. (Section 7.5)

Modification and Waiver

We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:

We may also modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments. We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. (Section 9.2) The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration. (Section 6.13)

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of any series (subject to certain exceptions). We will be so discharged upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the beneficial owners of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred. (Section 8.3)

Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

The conditions include:

recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal of, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities; and

No Personal Liability of Directors, Officers, Employees or Securityholders

None of our past, present or future directors, officers, employees or securityholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

The indenture and the debt securities, including any claim or controversy arising out of or relating to the indenture or the securities, will be governed by the laws of the State of New York.

The indenture will provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the indenture, the debt securities or the transactions contemplated thereby.

The indenture will provide that any legal suit, action or proceeding arising out of or based upon the indenture or the transactions contemplated thereby may be instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the City of New York, and we, the trustee and the holder of the debt securities (by their acceptance of the debt securities) irrevocably submit to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The indenture will further provide that service of any process, summons, notice or document by mail (to the extent allowed under any applicable statute or rule of court) to such party's address set forth in the indenture will be effective service of process for any suit, action or other proceeding brought in any such court. The indenture will further provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the courts specified above and irrevocably and unconditionally waive and agree not to plead or claim any such suit, action or other proceeding has been brought in an inconvenient forum. (Section 10.10)

DESCRIPTION OF WARRANTS

We may issue warrants to purchase common stock, preferred stock or debt securities. The applicable prospectus supplement will describe, to the extent applicable, the following terms of any warrants:

SELLING STOCKHOLDERS

Information about selling stockholders, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment to the registration statement of which this prospectus is a part, or in filings we make with the SEC under the Exchange Act that are incorporated by reference.

PLAN OF DISTRIBUTION

We or any selling stockholders may sell securities:

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

We or any selling stockholders may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act, and describe any commissions that we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement. The distribution of the securities may be effected from time to time in one or more transactions:

Each prospectus supplement will describe the method of distribution of the securities in respect of which the prospectus supplement is delivered and any applicable restrictions.

A prospectus supplement or supplements (and any related free writing prospectus) will describe the terms of the offering of the securities in respect of which the prospectus supplement is delivered, including the following:

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we or any selling stockholders will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

If a dealer is utilized in the sale of the securities in respect of which this prospectus is delivered, we or any selling stockholders will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

In connection with the offering of securities, we or any selling stockholders may grant to the underwriters an option to purchase additional securities with an additional underwriting commission, as may be set forth in the applicable prospectus supplement.

Remarketing firms, agents, underwriters, dealers and other persons may be entitled under agreements which they may enter into with us or any selling stockholders to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

If so indicated in the applicable prospectus supplement, we or any selling stockholders will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

Certain agents, underwriters and dealers, and their associates and affiliates may be customers of, have borrowing relationships with, engage in other transactions with, and/or perform services, including investment banking services, for us, one or more of our respective affiliates or any selling stockholders in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise or the securities are sold by us to an underwriter in a firm commitment underwritten offering. The applicable prospectus supplement may provide that the original issue date for your securities may be more than one scheduled business day after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the first business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than one scheduled business day after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

The securities may be new issues of securities and may have no established trading market. The securities may or may not be listed on a national securities exchange. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

LEGAL MATTERS

Unless the applicable prospectus supplement indicates otherwise, the validity of the securities in respect of which this prospectus is being delivered will be passed upon by Proskauer Rose LLP, New York, New York. Any underwriters will also be advised about the validity of the securities and other legal matters by their own counsel, which will be named in the applicable prospectus supplement.

The selling stockholder has not had any position within, held any office of or had any other material relationship with us or our affiliates during the past three years. The information in the table below regarding shares of common stock to be beneficially owned after the offering assumes the sale of all shares being offered by the selling stockholder under this prospectus supplement.

PLAN OF DISTRIBUTION

Resales by the Selling Stockholder

We are registering the shares of common stock on behalf of the selling stockholder pursuant to the terms of that certain Asset Purchase Agreement, dated as of January 23, 2026 (the "Asset Purchase Agreement"), we entered into in connection with our acquisition from Cardlytics, Inc. of all the assets, properties and rights that are primarily related to, or primarily used in, the Bridg platform.

The selling stockholder may offer the shares of common stock from time to time, either in increments or in a single transaction. The selling stockholder may also decide not to sell all the shares of common stock it is allowed to sell under this prospectus supplement. The selling stockholder will act independently of us in making decisions with respect to the timing, manner and size of each sale.

The term "selling stockholder" also includes persons who obtain common stock from the selling stockholder as a gift, on foreclosure of a pledge, in a distribution or dividend of assets by an entity to its equity holders or partners, as an assignee, transferee or other successor-in-interest, or in another private transaction.

Types of Sale Transactions

The selling stockholder may sell the shares of common stock offered by this prospectus supplement at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices or at fixed prices that may be changed. Sales of shares of our common stock by the selling stockholder may occur from time to time in one or more of the following types of transactions (which may involve crosses or block transactions):

The selling stockholder may enter into hedging transactions from time to time in which it may:

The selling stockholder may use broker-dealers or other persons to sell its shares in transactions that may include one or more of the following:

Resales by the selling stockholder may be made directly to investors or through securities firms acting as underwriters, brokers or dealers. When resales are to be made through a securities firm, the securities firm may be engaged to act as the selling stockholder's agent in the resale of the shares of common stock by the selling stockholder, or the securities firm may purchase shares of our common stock from the selling stockholder as principal and thereafter resell those shares from time to time. The fees earned by or paid to the securities firm may be the normal stock exchange commission or negotiated commissions or underwriting discounts to the extent permissible. The securities firm may resell the securities through other securities dealers, and commissions or concessions to those other dealers may be allowed.

The selling stockholder and any agent, broker or dealer that participates in sales of common stock offered by this prospectus supplement may be deemed "underwriters" under the Securities Act, and any commissions or other consideration received by any agent, broker or dealer may be considered underwriting discounts or commissions under the Securities Act.

Instead of selling shares of common stock under this prospectus supplement, the selling stockholder may sell shares of common stock in compliance with the provisions of Rule 144 or applicable exemptions from registration under the Securities Act, if available.

Regulation M

We have informed the selling stockholder that the anti-manipulation provisions of Regulation M under the Exchange Act may apply to its sales of common stock.

Effectiveness of Registration Statement

Under the Asset Purchase Agreement, we will use commercially reasonable efforts to keep the registration statement of which this prospectus supplement and the accompanying base prospectus are part effective until the earlier of (1) the selling stockholder ceases to hold the shares of our common stock issued in connection with the closing pursuant to the Asset Purchase Agreement, (2) the date as of which all of the registrable securities have been sold pursuant to Rule 144 of the Securities and (3) the date as of which all such shares may be sold without any limitation as to volume or manner of sale restrictions pursuant Rule 144 of the Securities Act and any restrictive legend has been removed from such shares.

Expenses

Pursuant to the Asset Purchase Agreement, we and the selling stockholder have agreed that, subject to certain exceptions, all costs and expenses, including, without limitation, fees and disbursements of counsel, financial advisors and accountants, incurred in connection with the acquisition shall be paid by the party incurring such costs and expenses.

PART II

 

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth the fees and expenses payable by us in connection with the sale of the offered securities being registered hereby, other than underwriting discounts and commissions.

The following summary is qualified in its entirety by reference to the complete Delaware General Corporation Law ("DGCL") and our restated certificate of incorporation (the "Certificate of Incorporation"), and our amended and restated bylaws (the "Bylaws").

Section 145 of the DGCL provides, generally, that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (except actions by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. A corporation may similarly indemnify such person for expenses actually and reasonably incurred by such person in connection with the defense or settlement of any action or suit by or in the right of the corporation, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in the case of claims, issues and matters as to which such person shall have been adjudged liable to the corporation, provided that a court shall have determined, upon application, that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

Section 102(b)(7) of the DGCL provides, generally, that our certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director or officer to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director or officer, provided that such provision may not eliminate or limit the liability of (i) a director or officer for any breach of the director's or officer's duty of loyalty to the corporation or its shareholders, (ii) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) a director under section 174 of the DGCL, or (iv) a director or officer for any transaction from which the director derived an improper personal benefit. No such provision may eliminate or limit the liability of a director or officer for any act or omission occurring prior to the date when such provision became effective.

The Bylaws provide that the registrant shall to the fullest extent permitted by law indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was or has agreed

to become a director or officer of the registrant, or is or was serving or has agreed to serve at the request of the registrant as a director or officer, of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, and may indemnify any person who was or is a party or is threatened to be made a party to such an action, suit or proceeding by reason of the fact that such person is or was or has agreed to become an employee or agent of the registrant, or is or was serving or has agreed to serve at the request of the registrant as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person or on such person's behalf in connection with such action, suit or proceeding and any appeal therefrom, if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the registrant, and, with respect to any criminal action or proceeding had no reasonable cause to believe such person's conduct was unlawful; except that in the case of an action or suit by or in the right of the registrant to procure a judgment in its favor (1) such indemnification shall be limited to expenses (including attorneys' fees) actually and reasonably incurred by such person in the defense or settlement of such action or suit, and (2) no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the registrant unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper.

The Bylaws also provide that expenses (including attorneys' fees) incurred by a director or officer in defending any civil, criminal, administrative or investigative action, suit or proceeding shall to the fullest extent permitted by law be paid by the registrant in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the registrant as authorized in the Bylaws.

The Bylaws provide that the foregoing indemnification provisions shall be deemed to be a contract between the registrant and each director and officer who serves in any such capacity at any time while these provisions as well as the relevant provisions of the DGCL are in effect and any repeal or modification thereof shall not affect any right or obligation then existing with respect to any state of facts then or previously existing or any action, suit or proceeding previously or thereafter brought or threatened based in whole or in part upon any such state of facts. The Bylaws provide that such contract right may not be modified retroactively without the consent of such director or officer.

The Bylaws provide that the foregoing indemnification shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any by-law, agreement, vote of shareholders or disinterested directors or otherwise, both as to action in the indemnified person's official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

The Bylaws provide that the registrant shall purchase and maintain insurance on behalf of any person who is or was or has agreed to become a director or officer of the registrant, or is or was serving at the request of the registrant as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him or her and incurred by him or her or on his or her behalf in any such capacity, or arising out of his or her status as such, whether or not the registrant would have the power to indemnify him or her against such liability under the provisions of the Bylaws, provided that such insurance is available on acceptable terms, which determination shall be made by a vote of a majority of the entire board of directors.

The Certificate of Incorporation relieves the registrant's directors from personal liability for monetary damages to the registrant or its shareholders for breach of such director's fiduciary duty, except for liability (i) for any breach of the director's duty of loyalty to the registrant or its shareholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for willful or negligent violations of certain provisions in the DGCL imposing certain requirements with respect to stock repurchases, redemptions and dividends, or (iv) for any transaction from which the director derived an improper personal benefit. The Certificate of Incorporation relieves the registrant's officers from personal liability for monetary damages to the registrant or its shareholders for breach of such officer's fiduciary duty, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL.
