On October 14, 2020 (the “Closing Date”), CuriosityStream Inc., a Delaware corporation (formerly named Software Acquisition Group Inc.) (the “Company”), consummated the merger pursuant to that certain Agreement and Plan of Merger (the “Merger Agreement”), dated August 10, 2020, by and among the Company, CS Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of the Company (“Merger Sub”), CuriosityStream Operating Inc., a Delaware corporation (subsequently renamed Curiosity Inc.) (“Legacy CuriosityStream”), and Hendricks Factual Media LLC, a Delaware limited liability company (“HFM”).

PROSPECTUS SUMMARY

The following summary highlights selected information contained elsewhere in this prospectus and does not contain all of the information that you should consider in making your investment decision. Before investing in our securities, you should carefully read this entire prospectus and the information incorporated by reference, including the information set forth under “Risk Factors.” Some of the statements in this prospectus constitute forward-looking statements. See “Cautionary Statement Regarding Forward-Looking Statements.”

Our mission is to provide premium factual entertainment that informs, enchants and inspires. We are seeking to meet demand for high-quality factual entertainment via subscription video on-demand (“SVoD”) platforms, as well as via bundled content licenses for SVoD and linear offerings, partner bulk sales, brand partnerships and content sales. We are well-positioned for growth as a digital-native video platform monetizing content across this broad revenue stack.

Through the rapid expansion of our library of high-quality titles and by exploiting multiple channels to monetize our programming, we believe that we have achieved global leadership in factual content streaming, and are well positioned to capitalize on favorable ongoing industry trends to create value for our shareholders and other stakeholders.

Corporate Information

We are a Delaware corporation. Our principal executive offices are located at 8484 Georgia Ave., Suite 700, Silver Spring, Maryland 20910, and our telephone number is (301) 755-2050. Our corporate website address is www.investors.curiositystream.com.

Implications of Being an Emerging Growth Company

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”). As such, we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. If some investors find our securities less attractive as a result, there may be a less active trading market for our securities and the prices of our securities may be more volatile.

In addition, Section 107 of the JOBS Act also provides that 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. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We intend to take advantage of the benefits of this extended transition period.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of our initial public offering, or (b) in which we have total annual gross revenue of at least $1.07billion, (2) the date on which we have issued more than $1.0billion in non-convertible debt securities during the prior three-year period and (3) the date on which we are deemed to be a large accelerated filer under the rules of the SEC. References herein to emerging growth company will have the meaning associated with it in the JOBS Act.

An investment in our securities involves a high degree of risk. You should carefully consider the risks set forth under “Risk Factors” in any applicable prospectus, under “Risk Factors” under Item 1A of Part I of our Annual Report on Form 10-K filed with the SEC, and in any Quarterly Report on Form 10-Q filed with the SEC subsequent thereto, each, incorporated by reference herein, and all of the other information contained or incorporated by reference in this prospectus, before investing in our securities. If any of these events occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment. In addition, much of the business information, as well as the financial and operational data contained in our risk factors, are updated by our periodic reports filed with the SEC pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which are also incorporated by reference into this prospectus. For more information, see “Where You Can Find More Information” and “Information Incorporated by Reference.”

We will not receive any of the proceeds from the sale of the shares of our Common Stock by the selling securityholders.

The following is a description of the material terms of, and is qualified in its entirety by, the Second Amended and Restated Certificate of Incorporation of the Company (the “Charter”) and the Amended and Restated Bylaws of the Company (the “Bylaws”). We urge you to read in their entirety our Charter and Bylaws. For information on how to obtain copies of such documents, please see “Where You Can Find More Information”.

Our authorized capital stock consists of 125,000,000 shares of common stock, $0.0001 par value per share, and 1,000,000 shares of undesignated preferred stock, $0.0001 par value per share. No shares of preferred stock are issued or outstanding. We have issued all shares of our capital stock in uncertificated form. As of March 25, 2022, there were 52,761,542 shares of Common Stock outstanding.

Holders of 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 or removal of directors. Holders of Common Stock vote together as a single class on all matters submitted to a vote of our stockholders, except as required by law. Unless specified in our Charter or Bylaws, or as required by applicable provisions of the Delaware General Corporation Law (the “DGCL”) or applicable stock exchange rules, the affirmative vote of a majority of the shares of Common Stock that are voted is required to approve any such matter voted on by its stockholders. The board of directors of the Company (the “Board”) is divided into three classes, each of which generally serve for a term of three years with only one class of directors being elected each year. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting shares are able to elect all of the directors. Our stockholders are entitled to receive ratable dividends, if any, as may be declared from time-to-time by our Board out of legally available funds.

Our Charter provides that shares of preferred stock may be issued from time to time in one or more series. Our Board is authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. Our Board is able, without stockholder approval, to issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of our Common Stock and could have anti-takeover effects. The ability of our Board to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no preferred stock outstanding at the date hereof. Although we do not currently intend to issue any shares of preferred stock, we cannot assure you that we will not do so in the future.

The warrants issued to Software Acquisition Holdings LLC in the private placement that closed concurrently with our IPO (the “Private Placement Warrants”), the warrants issued to PIPE Investors in connection with our Business Combination (the “PIPE Warrants”) and the warrants sold as part of the Units in the IPO (the “Public Warrants”, together with the Private Placement Warrants and the PIPE Warrants, the “Warrants”), were issued in registered form under a Warrant Agreement between Continental Stock Transfer & Trust Company (the “Warrant Agent”), and the Company (the “Warrant Agreement”), as amended. The Warrant Agreement provides that the terms of the Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by 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.

The Warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the Warrant Agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to us, for the number of Warrants being exercised. The warrantholders do not have the rights or privileges of holders of Common Stock and any voting rights until they exercise their Warrants and receive shares of Common Stock. After the issuance of shares of Common Stock upon exercise of the Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by our stockholders.

Each whole Warrant entitles the registered holder to purchase one whole share of Common Stock at a price of $11.50 per share, subject to adjustment as discussed below. Pursuant to the Warrant Agreement, a warrantholder may exercise its Warrants only for a whole number of shares of Common Stock. This means that only a whole Warrant may be exercised at any given time by a warrantholder. Only whole Warrants are traded. The Warrants will expire on October 14, 2025, at 5:00 p.m. Eastern Time, or earlier upon redemption or liquidation.

No Warrant is exercisable and we will not be obligated to issue shares of Common Stock upon exercise of a Warrant unless Common Stock issuable upon such Warrant exercise has been registered, qualified, or deemed to be exempt under the securities laws of the state of residence of the registered holder of such Warrant. In the event that the conditions in the immediately preceding sentence are not satisfied with respect to a Warrant, the holder of such Warrant will not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless. In no event will we be required to net cash settle any Warrant. In the event that a registration statement is not effective for the exercised Warrants, the purchaser of a Unit containing such Warrant will have paid the full purchase price for the Unit solely for the share of Common Stock underlying such Unit.

During any period when we will have failed to maintain an effective registration statement with respect to the Warrants or the Common Stock issuable upon exercise of the Warrants, warrantholders may exercise Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. If that exemption, or another exemption, is not available, holders will not be able to exercise their Warrants on a cashless basis.

If and when the Warrants become redeemable, we may not exercise our redemption right if the issuance of shares of Common Stock upon exercise of the Warrants is not exempt from registration or qualification under applicable state blue sky laws or we are unable to effect such registration or qualification. We will use our best efforts to register or qualify such shares of Common Stock under the blue sky laws of the state of residence in those states in which the Warrants were offered by us in our IPO.

We established the last of the redemption criteria discussed above to prevent a redemption call unless there is, at the time of the call, a significant premium to the Warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the Warrants, each warrantholder is entitled to exercise its Warrant prior to the scheduled redemption date. However, the price of the Common Stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) as well as the $11.50 Warrant exercise price after the redemption notice is issued.

If we call the Warrants for redemption as described above, our management will have the option to require any holder that wishes to exercise its Warrant to do so on a “cashless basis.” In determining whether to require all holders to exercise their Warrants on a “cashless basis,” management will consider, among other factors, our cash position, the number of Warrants that are outstanding and the dilutive effect on stockholders of issuing the maximum number of shares of Common Stock issuable upon the exercise of the Warrants. If our management takes advantage of this option, all holders of Warrants would pay the exercise price by surrendering their Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference between the exercise price of the Warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of the Common Stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of Warrants. If our management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Warrants, including the “fair market value” in such case. Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a Warrant redemption. We believe this feature is an attractive option to the Company if it does not need the cash from the exercise of the Warrants. If we call our Warrants for redemption and our management does not take advantage of this option, the Company’s former sponsor, Software Acquisition Group LLC (“Sponsor”), and its permitted transferees would still be entitled to exercise their Private Placement Warrants for cash or on a cashless basis using the same formula described above that other warrantholders would have been required to use had all warrantholders been required to exercise their Warrants on a cashless basis, as described in more detail below.

A holder of a Warrant may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such Warrant, to the extent that, to the Warrant Agent’s actual knowledge, after giving effect to such exercise, such person (together with such person’s affiliates) would beneficially own in excess of 4.9% or 9.8% (or such other amount as a holder may specify) of the shares of Common Stock outstanding immediately after giving effect to such exercise.

If the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Warrant will be increased in proportion to such increase in the outstanding shares of Common Stock. A rights offering to holders of Common Stock entitling holders to purchase shares of Common Stock at a price less than the fair market value will be deemed a stock dividend of a number of shares of Common Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Common Stock) and (ii) one minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided by (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for Common Stock, in determining the price payable for Common Stock, any consideration received for such rights, as well as any additional amount payable upon exercise or conversion, will be taken into account and (ii) fair market value means the volume weighted average price of Common Stock as reported during the 10-day trading period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if we, at any time while the Warrants are outstanding and unexpired, pay a dividend or make a distribution in cash, securities, or other assets to the holders of Common Stock on account of such shares of Common Stock (or other shares of our capital stock into which the Warrants are convertible), other than (a) as described above or (b) certain ordinary cash dividends, then the Warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each share of Common Stock in respect of such event.

If the number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant will be decreased in proportion to such decrease in outstanding shares of Common Stock.

Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as described above, the Warrant exercise price will be adjusted by multiplying the Warrant exercise price immediately prior to such adjustment by a fraction, (x) the numerator of which will be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of shares of Common Stock so purchasable immediately thereafter.

In case of any reclassification or reorganization of the outstanding shares of Common Stock (other than those described above or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of us with or into another corporation (other than a consolidation or merger in which we are the continuing corporation and that does not result in any reclassification or reorganization of our outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety in connection with which we are dissolved, the warrantholders will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised their Warrants immediately prior to such event. If less than 70% of the consideration receivable by the holders of Common Stock in such a transaction is payable in the form of common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the Warrant properly exercises the Warrant within 30 days following public disclosure of such transaction, the Warrant exercise price will be reduced as specified in the Warrant Agreement based on the Black-Scholes value (as defined in the Warrant Agreement) of the Warrant. The purpose of such exercise price reduction is to provide additional value to warrantholders when an extraordinary transaction occurs during the exercise period of the Warrants pursuant to which the warrantholders otherwise do not receive the full potential value of the Warrants in order to determine and realize the option value component of the Warrant. This formula is to compensate the warrantholder for the loss of the option value portion of the Warrant due to the requirement that the warrantholder exercise the Warrant within 30 days of the event. The Black-Scholes model is an accepted pricing model for estimating fair market value where no quoted market price for an instrument is available.

Our annual stockholder meetings are held at a date, time and place exclusively selected by our Board. To the extent permitted under applicable law, we may conduct meetings by remote communications, including by webcast.

Anti-Takeover Effects of Our Charter and Bylaws and Certain Provisions of Delaware Law

Our Charter and Bylaws contain and the DGCL contains provisions, as summarized in the following paragraphs, that are intended to enhance the likelihood of continuity and stability in the composition of our Board. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change of control and enhance the ability of our Board to maximize stockholder value in connection with any unsolicited offer to acquire the Company. However, these provisions may have an anti-takeover effect and may delay, deter, or prevent a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of Common Stock held by stockholders.

Delaware law does not require stockholder approval for any issuance of authorized shares.

However, the listing requirements of NASDAQ, which would apply so long as our Common Stock remains listed on the NASDAQ, require stockholder approval of certain issuances equal to or exceeding 20% of the then-outstanding voting power of our capital stock or the-then outstanding number of shares of common stock. These additional shares may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

Our Board may generally issue preferred shares on terms calculated to discourage, delay or prevent a change of control of the Company or the removal of its management. Moreover, our authorized but unissued shares of preferred stock will be available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, to facilitate acquisitions and employee benefit plans.

One of the effects of the existence of unissued and unreserved Common Stock or preferred stock may be to enable our Board to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of the Company by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of our management and possibly deprive our stockholders of opportunities to sell their shares of Common Stock at prices higher than prevailing market prices.

Our Charter provides that our Board is classified into three classes of directors, with the classes to be as nearly equal in number as possible, and with each director serving a three-year term. As a result, approximately one-third of our Board members are elected each year. The classification of directors has the effect of making it more difficult for stockholders to change the composition of our Board. Our Charter and Bylaws provide that, subject to any rights of holders of preferred stock to elect additional directors under specified circumstances, the number of directors will be fixed from time to time exclusively pursuant to a resolution adopted by the Board.

The Company is subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. This statute prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with:

A “business combination” includes a merger or sale of more than 10% of our assets. However, the above provisions of Section 203 do not apply if:

Under the DGCL, and as provided in our Charter, a director serving on a classified board may be removed by the stockholders only for cause and only by the affirmative vote of holders of a majority in voting power of all outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class. In addition, our Charter provides that, subject to the rights granted to one or more series of preferred stock then outstanding and the rights granted pursuant to the Investor Rights Agreement (as defined below), any newly created directorship on our Board that results from an increase in the number of directors and any vacancies on our Board will be filled only by the affirmative vote of a majority of the remaining directors (other than directors elected by the holders of any series of preferred stock, voting separately as a series or together with one or more series, as the case may be), even if less than a quorum, by a sole remaining director or by the stockholders.

Under Delaware law, the right to vote cumulatively does not exist unless our Charter specifically authorizes cumulative voting. Our Charter does not authorize cumulative voting.

Our Charter provides that special meetings of our stockholders may be called at any time only by or at the direction of the chief executive officer, the Board or the chairperson of the Board pursuant to a resolution adopted by a majority of our Board. Our Bylaws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of the Company.

Requirements for Advance Notification of Director Nominations and Stockholder Proposals

Our Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the Board or a committee of the Board. In order for any matter to be “properly brought” before a meeting, a stockholder must comply with advance notice requirements and provide us with certain information. Generally, to be timely, a stockholder’s notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the immediately preceding annual meeting of stockholders. Our Bylaws also specify requirements as to the form and content of a stockholder’s notice. Our Bylaws allow our Board to adopt rules and regulations for the conduct of meetings as it deems appropriate, which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These provisions may also defer, delay, or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of us.

Under the DGCL, with certain exceptions, the Company’s stockholders have appraisal rights in connection with a merger or consolidation of the Company. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

Under the DGCL, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

Our Charter provides that unless we consent to the selection of an alternative forum, the Delaware Chancery Court will be the exclusive forum for any (1) derivative action or proceeding brought on our behalf, (2) action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of ours or our stockholders, (3) action asserting a claim against our Charter or our Bylaws, or (4) action asserting a claim against us, our directors, officers or employees governed by the internal affairs. Our Charter provides that the Delaware Chancery Court is the exclusive jurisdiction for any stockholder to bring any action asserting an “internal corporate claim” as defined in Section 115 of the DGCL. In addition, our Charter provides that the Federal District Courts of the United States of America are the exclusive forum for resolution of any complaint asserting a cause of action under the Securities Act, or with respect to the offer or sale of our securities.

Delaware law permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors, or stockholders. Our Charter, to the maximum extent permitted from time to time by Delaware law, renounces any interest or expectancy that we have in, or right to be offered an opportunity to participate in, specified business opportunities that are from time to time presented to our officers, directors or stockholders or their respective affiliates, other than those officers, directors, stockholders or affiliates who are our or our subsidiaries’ employees. Our Charter provides that, to the fullest extent permitted by law, none of the stockholder parties or any of their affiliates or any director who is not employed by us (including any non-employee director who serves as one of our officers in both his director and officer capacities) or his or her affiliates will have any duty to refrain from (1) engaging in a corporate opportunity in the same or similar lines of business in which we or our affiliates now engage or propose to engage or (2) otherwise competing with us or our affiliates. In addition, to the fullest extent permitted by law, in the event that any stockholder party or non-employee director acquires knowledge of a potential transaction or other business opportunity which may be a corporate opportunity for itself or himself or its or his affiliates or for us or our affiliates, such person will have no duty to communicate or offer such transaction or business opportunity to us or any of our affiliates and they may take any such opportunity for themselves or offer it to another person or entity. Our Charter does not renounce our interest in any business opportunity that is expressly offered to a non-employee director solely in his or her capacity as a director or officer of the Company. To the fullest extent permitted by law, no business opportunity is deemed to be a potential corporate opportunity for us unless we would be permitted to undertake the opportunity under our Charter, we have sufficient financial resources to undertake the opportunity and the opportunity would be in line with our business.

The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties, subject to certain exceptions. Our Charter includes a provision that eliminates the personal liability of directors for monetary damages for any breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. The effect of these provisions is to eliminate the rights of the Company and its stockholders, through stockholders’ derivative suits on our behalf, to recover monetary damages from a director for breach of fiduciary duty as a director, including breaches resulting from grossly negligent behavior. However, exculpation does not apply to any director if the director has acted in bad faith, knowingly or intentionally violated the law, authorized illegal dividends or redemptions or derived an improper benefit from his or her actions as a director.

Our Bylaws provide that we must indemnify and advance expenses to our directors and officers to the fullest extent authorized by the DGCL. We are also expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for our directors, officers and certain employees for some liabilities. We believe that these indemnification and advancement provisions and insurance are useful to attract and retain qualified directors and executive officers.

The limitation of liability, advancement and indemnification provisions in our Charter and Bylaws may discourage our stockholders from bringing a lawsuit against directors for breach of their fiduciary duty.

These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

There is currently no pending material litigation or proceeding involving our directors, officers or employees for which indemnification is sought.

In connection with the consummation of the Merger, we entered into an Investor Rights Agreement with Legacy CuriosityStream, the Sponsor, HFM and officers and directors of Legacy CuriosityStream (the “Investor Rights Agreement”).

Under the Investor Rights Agreement, we agree to nominate two (2) individuals designated by the Sponsor (each a “Sponsor Director”) for election as members of our Board if, at such time, the Board does not contain a Sponsor Director and the Sponsor and their affiliates (the “Sponsor Entities”) together continue to beneficially own at least 50% of the shares of our common stock entitled to vote generally in the election of directors as of the date of the consummation of the Merger. Further, under the Investor Rights Agreement, HFM and the officers and directors of Legacy CuriosityStream agree to vote in favor of, or otherwise consent to, the election or appointment of a Sponsor Director at any meeting of the stockholders under the terms set forth above. If the Sponsor does not elect to nominate two (2) Sponsor Directors, we will agree to permit the Sponsor to select one (1) non-voting observer to participate in any Board meeting (including any committee thereof), for so long as the Sponsor and its affiliates continue to beneficially own at least 50% of the shares of our common stock entitled to vote generally in the election of directors as of the date of the consummation of the Merger.

In the case of a vacancy on our Board created by the death, disability, disqualification, removal or resignation of a Sponsor Director, we agree to notify Sponsor of such vacancy and nominate an individual timely designated by the Sponsor for election to fill the vacancy, provided that such nomination would not constitute a breach by our Board of its fiduciary duties or applicable laws.

Pursuant to the Investor Rights Agreement, the Company must provide to certain Legacy CuriosityStream officers and directors certain customary “mandatory,” “demand” and “piggyback” registration rights in respect of its Common Stock.

In addition, in connection with the Registration Rights Agreement dated as of November 19, 2019 by and between the Company and the Sponsor, the Company must provide to certain Sponsor Entities certain customary “demand” and “piggyback” registration rights in respect of their securities of the Company.

Rule 144 under the Securities Act (“Rule 144”) is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

Upon the Closing of the Business Combination, the Company ceased to be a shell company and at least one year has elapsed from the time that the Company filed current Form 10 type information with the SEC reflecting its status as an entity that is not a shell company.

Now that Rule 144 has become available for the resale of our securities, a person who has beneficially owned restricted shares of our Common Stock or Warrants for at least six months would be entitled to sell their securities, provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (ii) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months (or such shorter period as we were required to file reports) preceding the sale.

Persons who have beneficially owned restricted shares of our Common Stock or Warrants for at least six months but who are our affiliates at the time of, or at any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

Sales by our affiliates under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

The term “selling securityholders” includes the securityholders listed in the table below and their permitted transferees.

The following table provides, as of November 20, 2020 (unless as of later date as indicated in the footnotes), information regarding the beneficial ownership of our Common Stock by each selling securityholder, the number of shares of our Common Stock that may be sold by each selling securityholder under this prospectus and that each selling securityholder will beneficially own after this offering.

Because each selling securityholder may dispose of all, none or some portion of their securities, no estimate can be given as to the number of securities that will be beneficially owned by a selling securityholder upon termination of this offering. For purposes of the table below, however, we have assumed that after termination of this offering none of the securities covered by this prospectus will be beneficially owned by the selling securityholders and further assumed that the selling securityholders will not acquire beneficial ownership of any additional securities during the offering. In addition, the selling securityholders may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time and from time to time, our securities in transactions exempt from the registration requirements of the Securities Act after the date on which the information in the table is presented.

We may amend or supplement this prospectus from time to time in the future to update or change this selling securityholders list and the securities that may be resold.

Please see the section titled “Plan of Distribution” for further information regarding the selling securityholders’ method of distributing these shares.

The selling securityholders include certain of our directors and their affiliates. For a description of our relationships with the selling securityholders and their affiliates not discussed above see the sections of our Definitive Proxy Statement filed with the SEC on April 29, 2021, entitled “Corporate Governance and Board Matters,” “Executive Compensation” and “Certain Relationships and Related Party Transactions.”

The selling securityholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of our Common Stock or interests in shares of our Common Stock received after the date of this prospectus from a selling securityholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of our Common Stock or interests in shares of our Common Stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling securityholders may use any one or more of the following methods when disposing of shares or interests therein:

In addition, a selling securityholder that is an entity may elect to make an in-kind distribution of securities to its members, partners or stockholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus with a plan of distribution. Such members, partners or stockholders would thereby receive freely tradeable securities pursuant to the distribution through a registration statement. To the extent a distributee is an affiliate of ours (or to the extent otherwise required by law), we may file a prospectus supplement in order to permit the distributees to use the prospectus to resell the securities acquired in the distribution.

The selling securityholders may, from time to time, pledge or grant a security interest in some or all of the shares of our Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of our Common Stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling securityholders to include the pledgee, transferee or other successors in interest as selling securityholders under this prospectus. The selling securityholders also may transfer the shares of our Common Stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of shares of our Common Stock or interests therein, the selling securityholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of our Common Stock in the course of hedging the positions they assume. The selling securityholders may also sell shares of our Common Stock short and deliver these securities to close out their short positions, or loan or pledge the shares of our Common Stock to broker-dealers that in turn may sell these securities. The selling securityholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling securityholders from the sale of the Common Stock offered by them will be the purchase price of the Common Stock less discounts or commissions, if any. Each of the selling securityholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of Common Stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

The selling securityholders and any underwriters, broker-dealers or agents that participate in the sale of the Common Stock or interests therein may be deemed “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling securityholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the shares of our Common Stock to be sold, the names of the selling securityholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the Common Stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the Common Stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling securityholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling securityholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling securityholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling securityholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the selling securityholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

We have agreed with the selling securityholders to keep the registration statement of which this prospectus constitutes a part effective until such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with the registration statement or such securities have been withdrawn.

The validity of the securities offered by this prospectus have been passed upon for us by Arnold & Porter Kaye Scholer LLP, New York, New York.

The following table sets forth all costs and expenses, other than underwriting discounts and commissions, in connection with the sale of our securities being registered, all of which will be paid by us. All amounts shown are estimates, except for the SEC registration fee.

Section 145 of the DGCL provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent of the registrant. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaws, agreement, vote of stockholders or disinterested directors or otherwise. The registrant’s certificate of incorporation and bylaws provide for indemnification by the registrant of its directors and officers to the fullest extent permitted by the DGCL.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions or (4) for any transaction from which the director derived an improper personal benefit. The registrant’s second amended and restated certificate of incorporation provides for such limitation of liability to the fullest extent permitted by the DGCL.

The registrant has entered into indemnification agreements with each of its directors and executive officers to provide contractual indemnification in addition to the indemnification provided in its second amended and restated certificate of incorporation. Each indemnification agreement provides for indemnification and advancements by the registrant of certain expenses and costs relating to claims, suits or proceedings arising from his or her service to the registrant or, at the registrant’s request, service to other entities, as officers or directors to the maximum extent permitted by applicable law. The registrant believes that these provisions and agreements are necessary to attract qualified directors and executive officers.

The registrant also maintains standard policies of insurance under which coverage is provided (1) to its directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act, while acting in their capacity as directors and officers of the registrant, and (2) to the registrant with respect to payments which may be made by the registrant to such officers and directors pursuant to any indemnification provision contained in the registrant’s second amended and restated certificate of incorporation and amended and restated bylaws or otherwise as a matter of law

All schedules have been omitted as not applicable or not required under the rules of Regulation S-X.

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that:

Paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act, that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) Each prospectus filed by a registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6) That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(7) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act, the Registrant has duly caused this Post-Effective Amendment No. 3 on Form S-3 to the Registration Statement on Form S-1 to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Silver Spring, Maryland, on March 31, 2022.

Pursuant to the requirements of the Securities Act, this Post-Effective Amendment No. 3 on Form S-3 to the Registration Statement on Form S-1 has been signed by the following persons in the capacities and on the dated indicated.
