ABOUT ASTRA SPACE, INC.

Astra’s mission is to improve life on Earth from space^® by launching a new generation of space products and services. These products and services are enabled by new constellations of small satellites in Low Earth Orbit (“LEO”), which have rapidly become smaller, cheaper, and many times more numerous than traditional satellites. We believe that frequent, reliable, dedicated launches and space products enabled by scaled manufacturing are the keys to accelerating the growth of the space economy.

Astra aims to develop and operate a mass-producible dedicated mobile orbital launch system. Our system consists of a small launch vehicle that can be transported inside standard shipping containers and mobile ground launch infrastructure that we designed to be rapidly deployed anywhere in the world we are licensed to operate and where our spaceports are located. This system is designed by Astra and manufactured in Astra’s vertically integrated rocket factory in Alameda, California, which we have designed to manufacture and integrate the majority of the components. Our launch system requires a launch site with little more than a concrete pad and only six Astra employees on-site. Our system is designed to meet the needs of modern LEO satellite constellations, allowing precise and rapid placement of individual satellites into their required orbits. We believe this makes Astra’s system more responsive and affordable than other launch alternatives for the thousands of LEO satellites which commercial companies and governments plan to launch in the coming decade.

We have made significant progress in the development of the system to date. On November 20, 2021, we successfully launched launch vehicle LV0007 into orbit at an inclination of 86.0 degrees, an altitude of 500 km and velocity of 7.61 km/s, making Astra one of the fastest U.S. companies to have successfully demonstrated the orbital placement of a test payload. We commenced paid commercial launch services in 2022. To date, we have had three commercial launches and have delivered 23 satellites into low earth orbit.

During the third quarter of 2022, we decided to focus on the development and production of the next version of our launch system, which we announced at our inaugural Spacetech Day on May 12, 2022. As a result, we have discontinued the production of launch vehicles supported by our previous launch system, Launch System 1, and commenced development of our new launch system, Launch System 2. We anticipate conducting our first test launch of Launch System 2 by the end of 2023 and commencing commercial launches beginning in 2024.

In addition to Launch Services, we also offer Space Products to LEO operators. Currently, under our Space Products segment, we offer an industry leading spacecraft engine platform consisting of two in-space electric propulsion systems. In 2022, we began delivery of our Astra Spacecraft Engines^TM to our customers. Currently, our spacecraft engines have more than 600 on-orbit burns making it one of the most proven spacecraft engine products in the market.

We believe that these two operating segments will create an integrated space services platform that will allow our customers to focus on innovative applications rather than investing in bespoke satellite development and separately contracting Launch Services. Further details of our current and expected future service offerings are provided below.

2

Our ability to achieve these goals and objectives by our planned timelines are conditional upon a number of factors, including our ability to successfully and timely develop our launch vehicles and our ability to effectively market and sell our services and products. See “Risk Factors” on page 17 of this prospectus.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The statements contained in this prospectus that are not purely historical are forward-looking statements. These statements are indicated by words or phrases such as “anticipate,” “expect,” “estimate,” “seek,” “plan,” “project,” “aim,” “believe,” “could,” “should,” “intend,” “will,” and similar words or phrases. These forward-looking statements may include projections of financial information; statements about historical results that may suggest trends for our business; statements of the plans, strategies, and objectives of management for future operations; statements of expectation or belief regarding future events (including any acquisitions we may make), technology developments, our products, product sales, expenses, liquidity, cash flow and growth rates. Such statements are based on management’s current expectations, estimates, forecasts and projections of our performance, our industry’s performance and macroeconomic conditions, based on management’s judgment, beliefs, and views on current trends and market conditions. Such forward-looking statements involve risks and uncertainties that may cause actual results to differ materially from those contained in the forward-looking statements. We derive most of our forward-looking statements from our operating budgets and forecasts, which are based upon many detailed assumptions. While we believe that our assumptions are reasonable, we caution that it is very difficult to predict the impact of known factors, and it is impossible for us to anticipate all factors that could affect our actual results and undertake no obligation to update or revise publicly any forward-looking statements, whether because of new information, future events, or otherwise. Accordingly, we caution readers not to place undue reliance on these statements. Forward-looking statements in this prospectus may include, for example, statements about:

These forward-looking statements are based on information available as of the date of this prospectus, and current expectations, forecasts and assumptions, and involve a number of judgments, risks and uncertainties. Important factors could cause actual results to differ materially from those indicated or implied by forward-looking statements such as those contained in documents we have filed with the SEC. Accordingly, forward-looking statements should not be relied upon as representing our views as of any subsequent date, and we do not undertake any obligation to update or revise forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

As a result of a number of known and unknown risks and uncertainties, our actual results or performance may be materially different from those expressed or implied by these forward-looking statements. For a discussion of the risks involved in our business and investing in our common stock, see the section entitled, “Risk Factors.”

Should one or more of these risks or uncertainties materialize, or should any of the underlying assumptions prove incorrect, actual results may vary in material respects from those expressed or implied by these forward-looking statements. You should not place undue reliance on these forward-looking statements.

RISK FACTORS

An investment in our securities involves risks and uncertainties. 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 for the year ended December 31, 2022, field with the SEC on March 30, 2023, incorporated by reference in this prospectus and all of the other information contained or incorporated by reference in this prospectus, before investing in our securities. We operate in a changing environment that involves numerous known and unknown risks and uncertainties that could materially adversely affect our operations. Any of these risks could materially and adversely affect our business, financial condition, results of operations or prospects. However, these risks are not the only risks facing us. Additional risks and uncertainties not currently known to us or those we currently view to be immaterial may also materially and adversely affect our business, financial condition, results of operations or prospects. In such a case, the trading price of our securities could decline and you may lose all or part of your investment in us. 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 Exchange Act, which are also incorporated by reference into this prospectus. For more information, see “Where You Can Find More Information” and “Incorporation of Documents by Reference” herein and the risks related to this offering set forth below:

Risk Factors Relating to the Offering

It is not possible to predict the actual number of shares of Class A Common Stock we will sell to the Selling Stockholder under the Purchase Agreement, or the actual gross proceeds that will result from those sales.

On August 2, 2022, we entered into the Purchase Agreement with the Selling Stockholder, pursuant to which the Selling Stockholder has committed to purchase up to $100,000,000 of our Class A Common Stock, subject to certain limitations and the satisfaction of the conditions set forth in the Purchase Agreement. From and after the Commencement Date, we will have the right, but not the obligation, to sell shares of Class A Common Stock to the Selling Stockholder pursuant to the Purchase Agreement from time to time over a period of up to 24 months beginning on September 13, 2022 (the “Commencement Date”). We generally have the right to control the timing and amount of any sales of our shares of Class A Common Stock to the Selling Stockholder under the Purchase Agreement. Sales of our Class A Common Stock, if any, to the Selling Stockholder under the Purchase Agreement will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to the Selling Stockholder all, some or none of the shares of our Class A Common Stock that may be available for us to sell to the Selling Stockholder pursuant to the Purchase Agreement. Depending on market liquidity at the time, resales of those shares by the Selling Stockholder may cause the public trading price of our Class A Common Stock to decrease.

Because the purchase price per share to be paid by the Selling Stockholder for the shares of Class A Common Stock that we may elect to sell to the Selling Stockholder under the Purchase Agreement, if any, will fluctuate based on the market prices of our Class A Common Stock at the time we elect to sell shares to the Selling Stockholder pursuant to the Purchase Agreement, if any, it is not possible for us to predict, as of the date of this prospectus and prior to any such sales, the number of shares of Class A Common Stock that we will sell to the Selling Stockholder under the Purchase Agreement, the purchase price per share that the Selling Stockholder will pay for shares purchased from us under the Purchase Agreement, or the aggregate gross proceeds that we will receive from those purchases by the Selling Stockholder under the Purchase Agreement.

Although the Purchase Agreement provides that we may sell up to an aggregate of $100,000,000 of our Class A Common Stock to Selling Stockholder, we are only registering 33,640,902 shares of our Class A Common Stock under this prospectus, which (a) excludes 359,098 of Initial Commitment Shares that we issued to Selling Stockholder upon execution of the Purchase Agreement and which has since been sold by the Selling Stockholder and (b) includes up to 359,097 Additional Commitment Shares that we may issue to the Selling Stockholder pursuant to the Purchase Agreement if certain conditions are met. If it becomes necessary for us to

6

issue and sell to the Selling Stockholder under the Purchase Agreement more than the 33,640,902 shares of Class A Common Stock being registered for resale under this prospectus in order to receive aggregate gross proceeds equal to $100,000,000 under the Purchase Agreement, we must file with the SEC one or more additional registration statements to register under the Securities Act the resale by the Selling Stockholder of any such additional shares of our Class A Common Stock we wish to sell from time to time under the Purchase Agreement, which the SEC must declare effective, in each case before we may elect to sell any additional shares of our Class A Common Stock to the Selling Stockholder under the Purchase Agreement.

Additionally, under the applicable rules of NASDAQ, in no event may we issue to the Selling Stockholder under the Purchase Agreement more than the Exchange Cap, unless we first (i) obtain stockholder approval to issue shares of Class A Common Stock in excess of the Exchange Cap under the Purchase Agreement in accordance with applicable NASDAQ rules and (ii) file with the SEC one or more additional registration statements to register under the Securities Act the resale by the Selling Stockholder of any such additional shares of our Class A Common Stock we wish to sell from time to time under the Purchase Agreement, which the SEC must declare effective, in each case before we may elect to sell any additional shares of our Class A Common Stock to the Selling Stockholder under the Purchase Agreement. In addition, the Selling Stockholder will not be required to purchase any shares of Class A Common Stock if such sale would result in the Selling Stockholder’s beneficial ownership exceeding the Beneficial Ownership Limitation, which is defined in the Purchase Agreement as 4.99% of the outstanding shares of Class A Common Stock. Our inability to access a portion or the full amount available under the Purchase Agreement, in the absence of any other financing sources, could have a material adverse effect on our business or results of operation.

Investors who buy shares of Class A Common Stock from the Selling Stockholder at different times will likely pay different prices and may experience different levels of return on their investments.

Pursuant to the Purchase Agreement, we will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold to the Selling Stockholder. If and when we do elect to sell shares of our Class A Common Stock to the Selling Stockholder pursuant to the Purchase Agreement, after the Selling Stockholder has acquired such shares, the Selling Stockholder may resell all, some or none of such shares at any time or from time to time in its discretion and at different prices. As a result, investors who purchase shares of our Class A Common Stock from the Selling Stockholder at different times will likely pay different prices for those shares, and so may experience different outcomes in their investment results. Investors may experience a decline in the value of the shares they purchase from the Selling Stockholder in this offering as a result of future sales made by us to the Selling Stockholder at prices lower than the prices such investors paid to the Selling Stockholder for their shares in this offering. In addition, if we sell a substantial number of shares of our Class A Common Stock to the Selling Stockholder under the Purchase Agreement, or if investors expect that we will do so, the actual sales of shares or the mere existence of our arrangement with the Selling Stockholder may make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales.

Raising additional capital may cause substantial dilution to our stockholders.

Any issuance and sale by us under the Purchase Agreement of a substantial amount of shares of our Class A Common Stock in addition to the shares of Class A Common Stock being registered for resale by the Selling Stockholder under this prospectus could cause additional substantial dilution to our stockholders. The number of shares of our Class A Common Stock ultimately offered for sale by the Selling Stockholder is dependent upon the number of shares of Class A Common Stock, if any, we ultimately elect to sell to the Selling Stockholder under the Purchase Agreement. In addition, we may seek capital through other means, including private and public equity offerings, “at-the-market” issuances, equity-linked and structured transactions, convertible debt financings and other committed equity financing arrangements.

We may use these proceeds from sales under the Purchase Agreement in ways with which you may not agree.

We will not receive any proceeds from the sale of the Class A Common Stock being offered by the Selling Stockholder pursuant to this prospectus. However, we may receive up to $100,000,000 in aggregate gross proceeds from sales of our Class A Common Stock to the Selling Stockholder pursuant to the Purchase Agreement that we may, in our discretion, elect to make, from and after the Commencement Date from time to time over a period of up to 24 months beginning on the Commencement Date. The net proceeds we receive from sales of shares of our Class A Common Stock, if any, under the Purchase Agreement, will depend on the frequency and prices at which we sell shares of Class A Common Stock to the Selling Stockholder after the

To the extent we sell Class A Common Stock to the Selling Stockholder, we currently intend to use any proceeds therefrom for general corporate purposes; however, we have considerable discretion in the application of the proceeds. Our stockholders and others interested in investing in our Class A Common Stock will not have the opportunity, as part of their investment decision, to assess whether the proceeds we may receive from sales of Class A Common Stock to the Selling Stockholder pursuant to the Purchase Agreement are being used by us in a manner agreeable to them. Our stockholders and others interested in investing in our Class A Common Stock must rely on management’s judgment regarding the application of these proceeds. The proceeds may be used for corporate purposes that do not immediately improve our profitability or increase the price of our Class A Common Stock.

THE COMMITTED EQUITY FINANCING

On August 2, 2022, we entered into the Purchase Agreement and the Registration Rights Agreement with the Selling Stockholder. Pursuant to the Purchase Agreement, subject to satisfaction of specified conditions in the Purchase Agreement on and after the Commencement Date, we will have the right to sell to the Selling Stockholder up to $100,000,000 of our Class A Common Stock, subject to certain limitations and conditions set forth in the Purchase Agreement, from time to time during the term of the Purchase Agreement. Sales of Class A Common Stock pursuant to the Purchase Agreement, and the timing of any sales, are solely at our option, and we are under no obligation to sell any securities to the Selling Stockholder under the Purchase Agreement. In accordance with our obligations under the Registration Rights Agreement, we have filed the registration statement, of which this prospectus forms a part, with the SEC to register under the Securities Act the resale by the Selling Stockholder of up to 34,000,000 shares of Class A Common Stock, consisting of (i) 359,097 Additional Commitment Shares that we may issue if certain conditions are met, in each case, to the Selling Stockholder as consideration for its commitment to purchase shares of Class A Common Stock at our election under the Purchase Agreement and (ii) up to 33,281,805 shares of Class A Common Stock that we may elect, in our sole discretion, to issue and sell to the Selling Stockholder, from time to time from and after the Commencement Date under the Purchase Agreement. We had previously registered for resale 359,098 Initial Commitment Shares that we issued to the Selling Stockholder upon the execution of the Purchase Agreement, which have since been sold by the Selling Stockholder and are not included in this prospectus.

We did not have the right to commence any sales of our Class A Common Stock to the Selling Stockholder under the Purchase Agreement until September 13, 2022 (the “Commencement Date”), which is the date on which all of the conditions to the Selling Stockholder’s purchase obligation set forth in the Purchase Agreement have been initially satisfied, including that the registration statement that includes this prospectus be declared effective by the SEC and the final form of this prospectus is filed with the SEC. From and after the Commencement Date, we will have the right, but not the obligation, from time to time at our sole discretion over the 24-month period beginning on the Commencement Date, to direct the Selling Stockholder to purchase up to a specified maximum amount of shares of Class A Common Stock in one or more VWAP Purchases and Intraday VWAP Purchases as set forth in the Purchase Agreement by timely delivering a written Purchase Notice for each VWAP Purchase, and timely delivering a written Intraday VWAP Purchase Notice for each Intraday VWAP Purchase, if any, to the Selling Stockholder in accordance with the Purchase Agreement on any trading day we select as the Purchase Date therefor, so long as (i) the closing sale price of our Class A Common Stock on the trading day immediately prior to such Purchase Date is not less than the Threshold Price and (ii) all shares of Class A Common Stock subject to all prior VWAP Purchases and all prior Intraday VWAP Purchases effected by us under the Purchase Agreement have been received by the Selling Stockholder prior to the time we deliver such notice to the Selling Stockholder. The “Threshold Price,” which shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split or other similar transaction and, effective upon the consummation of any such reorganization, recapitalization, non-cash dividend, stock split or other similar transaction, shall mean the lower of (i) such adjusted price and (ii) $1.00. On May 3, 2023, the per share closing sale price of our Class A Common Stock was $0.3816.

From and after the Commencement Date, the Company will control the timing and amount of any sales of Class A Common Stock to the Selling Stockholder. Actual sales of shares of our Class A Common Stock to the Selling Stockholder under the Purchase Agreement will depend on a variety of factors to be determined by us from time to time, including, among other things, market conditions, the trading price of our Class A Common Stock and determinations by us as to the appropriate sources of funding for the Company and its operations.

Under the applicable NASDAQ rules, in no event may we issue to the Selling Stockholder under the Purchase Agreement shares of Class A Common Stock in excess of the Exchange Cap, which is 53,059,650 shares of Class A Common Stock (such number of shares equal to 19.99% of the shares of the Common Stock outstanding immediately prior to the execution of the Purchase Agreement), unless (i) we obtain stockholder approval to issue shares of Class A Common Stock in excess of the Exchange Cap in accordance with applicable

9

NASDAQ rules, or (ii) the average price per share paid by the Selling Stockholder for all of the shares of Class A Common Stock that we direct the Selling Stockholder to purchase from us pursuant to the Purchase Agreement, if any, equals or exceeds $1.424 per share (representing the lower of the official closing price of our Class A Common Stock on NASDAQ on the trading day immediately preceding the date of the Purchase Agreement and the average official closing price of our Class A Common Stock on NASDAQ for the five consecutive trading days ending on the trading day immediately preceding the date of the Purchase Agreement, as adjusted pursuant to applicable NASDAQ rules). Moreover, we may not issue or sell any shares of Class A Common Stock to the Selling Stockholder under the Purchase Agreement which, when aggregated with all other shares of Class A Common Stock then beneficially owned by the Selling Stockholder and its affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 thereunder), would result in the Selling Stockholder beneficially owning any shares of Class A Common Stock in excess of the Beneficial Ownership Limitation, which is defined in the Purchase Agreement as 4.99% of the outstanding shares of Class A Common Stock.

The net proceeds from sales, if any, under the Purchase Agreement, will depend on the frequency and prices at which we sell shares of Class A Common Stock to the Selling Stockholder. To the extent we sell shares under the Purchase Agreement, we currently plan to use any proceeds therefrom for general corporate purposes.

Neither we nor the Selling Stockholder may assign or transfer any of our respective rights and obligations under the Purchase Agreement or the Registration Rights Agreement, and no provision of the Purchase Agreement or the Registration Rights Agreement may be modified or waived by the parties.

As consideration for the Selling Stockholder’s commitment to purchase shares of our Class A Common Stock at our direction upon the terms and subject to the conditions set forth in the Purchase Agreement, we issued 359,098 shares of our Class A Common Stock to the Selling Stockholder upon execution of the Purchase Agreement, which shares have since been sold pursuant to the prospectus declared effective on September 13, 2022. In addition, (i) upon our receipt of total aggregate gross cash proceeds equal to $25,000,000 from the Selling Stockholder under the Purchase Agreement (if any), we will issue 179,549 additional shares of our Class A Common Stock to the Selling Stockholder as Additional Commitment Shares, and (ii) upon our receipt of total aggregate gross cash proceeds equal to $50,000,000 from the Selling Stockholder under the Purchase Agreement (if any), we will issue an additional 179,548 shares of our Class A Common Stock to the Selling Stockholder as Additional Commitment Shares, totaling 359,097 Additional Commitment Shares Furthermore, in conjunction with the execution of the Purchase Agreement, we paid $125,000 to the Selling Stockholder in reimbursement of the reasonable legal fees and disbursements of the Selling Stockholder’s legal counsel. In addition, we agreed to pay the Selling Stockholder up to $7,500 per fiscal quarter in reimbursement of its reasonable legal fees and disbursements, in each case in connection with the transactions contemplated by the Purchase Agreement and the Registration Rights Agreement.

The Purchase Agreement and the Registration Rights Agreement contain customary representations, warranties, conditions and indemnification obligations of the parties. The descriptions of the Purchase Agreement and Registration Agreement described in this prospectus are qualified in their entirety to the actual text of such documents on file as exhibits to the registration statement that includes this prospectus, which are also available electronically on the SEC’s website at www.sec.gov.

Purchases of Class A Common Stock Under the Purchase Agreement

VWAP Purchases

From and after the Commencement Date, we will have the right, but not the obligation, from time to time at our sole discretion over the 24-month period beginning on the Commencement Date, to direct the Selling Stockholder to purchase a specified number of shares of Class A Common Stock, not to exceed the applicable Purchase Maximum Amount in a VWAP Purchase under the Purchase Agreement, by timely delivering a

The actual number of shares of Class A Common Stock that the Selling Stockholder will be required to purchase in a VWAP Purchase, which we refer to as the Purchase Share Amount, will be equal to the number of shares that we specify in the applicable Purchase Notice, subject to adjustment to the extent necessary to give effect to the applicable Purchase Maximum Amount and other applicable limitations set forth in the Purchase Agreement, including the Beneficial Ownership Limitation and, if then applicable, the Exchange Cap.

The per share purchase price that the Selling Stockholder will be required to pay for the Purchase Share Amount in a VWAP Purchase effected by us pursuant to the Purchase Agreement, if any, will be equal to the VWAP of our Class A Common Stock for the applicable Purchase Valuation Period on the Purchase Date for such VWAP Purchase, less a fixed 3.0% discount to the VWAP for such Purchase Valuation Period. The Purchase Valuation Period for a VWAP Purchase is defined in the Purchase Agreement as the period beginning at the official open (or “commencement”) of the regular trading session on NASDAQ on the applicable Purchase Date for such VWAP Purchase, and ending at the earliest to occur of:

The Intraday Purchase Maximum Amount applicable to such Intraday VWAP Purchase will be equal to the lesser of:

The actual number of shares of Class A Common Stock that the Selling Stockholder will be required to purchase in an Intraday VWAP Purchase, which we refer to as the Intraday Purchase Share Amount, will be equal to the number of shares that we specify in the applicable Intraday VWAP Purchase Notice, subject to adjustment to the extent necessary to give effect to the applicable Intraday Purchase Maximum Amount and other applicable limitations set forth in the Purchase Agreement, including the Beneficial Ownership Limitation and, if then applicable, the Exchange Cap.

The per share purchase price that the Selling Stockholder will be required to pay for the Intraday Purchase Share Amount in an Intraday VWAP Purchase effected by us pursuant to the Purchase Agreement, if any, will be calculated in the same manner as in the case of a regular VWAP Purchase, except that the VWAP used to determine the purchase price for the Intraday Purchase Share Amount to be purchased in an Intraday VWAP Purchase will be equal to the VWAP for the applicable Intraday Purchase Valuation Period on the Purchase Date for such Intraday VWAP Purchase, less a fixed 3.0% discount to the VWAP for such Intraday Purchase Valuation Period. The Intraday Purchase Valuation Period for an Intraday VWAP Purchase is defined in the Purchase Agreement as the period during the regular trading session on NASDAQ on such Purchase Date, beginning at the latest to occur of:

and ending at the earliest to occur of:

12

We may, in our sole discretion, timely deliver multiple Intraday VWAP Purchase Notices to the Selling Stockholder prior to 3:30 p.m., New York City time, on a single Purchase Date to effect multiple Intraday VWAP Purchases on such same Purchase Date, provided that the Purchase Valuation Period for any earlier regular VWAP Purchase effected on the same Purchase Date (as applicable) and the Intraday Purchase Valuation Period for the most recent prior Intraday VWAP Purchase effected on the same Purchase Date have ended prior to 3:30 p.m., New York City time, on such Purchase Date, and so long as all shares of Class A Common Stock subject to all prior VWAP Purchases and all prior Intraday VWAP Purchases effected by us under the Purchase Agreement, including those effected earlier on the same Purchase Date (as applicable), have been received by the Selling Stockholder prior to the time we deliver to the Selling Stockholder a new Intraday VWAP Purchase Notice to effect an additional Intraday VWAP Purchase on the same Purchase Date as an earlier regular VWAP Purchase (as applicable) and one or more earlier Intraday VWAP Purchases effected on such same Purchase Date.

The terms and limitations that will apply to each subsequent additional Intraday VWAP Purchase effected on the same Purchase Date will be the same as those applicable to any earlier regular VWAP Purchase (as applicable) and any earlier Intraday VWAP Purchase effected on the same Purchase Date as such subsequent additional Intraday VWAP Purchase, and the per share purchase price for the shares of Class A Common Stock that we elect to sell to the Selling Stockholder in each subsequent additional Intraday VWAP Purchase effected on the same Purchase Date as an earlier regular VWAP Purchase (as applicable) and/or earlier Intraday VWAP Purchase(s) effected on such Purchase Date will be calculated in the same manner as in the case of such earlier regular VWAP Purchase (as applicable) and such earlier Intraday VWAP Purchase(s) effected on the same Purchase Date as such subsequent additional Intraday VWAP Purchase, with the exception that the Intraday VWAP Purchase Valuation Period(s) for each subsequent additional Intraday VWAP Purchase will begin and end at different times (and may vary in duration) during the regular trading session on such Purchase Date, in each case as determined in accordance with the Purchase Agreement.

In the case of the VWAP Purchases and Intraday VWAP Purchases effected by us under the Purchase Agreement, if any, all share and dollar amounts used in determining the purchase price per share of Class A Common Stock to be purchased by the Selling Stockholder in a VWAP Purchase or an Intraday VWAP Purchase (as applicable), or in determining the applicable maximum purchase share amounts or applicable volume or price threshold amounts in connection with any such VWAP Purchase or Intraday VWAP Purchase (as applicable), in each case, will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction occurring during any period used to calculate such per share purchase price, maximum purchase share amounts or applicable volume or price threshold amounts.

At or prior to 5:30 p.m., New York City time, on the applicable Purchase Date for a VWAP Purchase and/or an Intraday VWAP Purchase, the Selling Stockholder will provide us with a written confirmation for such VWAP Purchase and/or Intraday VWAP Purchase, as applicable, setting forth the applicable purchase price (both on a per share basis and the total aggregate purchase price) to be paid by the Selling Stockholder for the

13

shares of Class A Common Stock purchased by the Selling Stockholder in such VWAP Purchase and/or Intraday VWAP Purchase, as applicable.

The payment for, against delivery of, shares of Class A Common Stock purchased by the Selling Stockholder in any VWAP Purchase or any Intraday VWAP Purchase under the Purchase Agreement will be fully settled within two trading days immediately following the applicable Purchase Date for such VWAP Purchase or such Intraday VWAP Purchase (as applicable), as set forth in the Purchase Agreement.

Conditions Precedent to Commencement and Each VWAP Purchase

The Selling Stockholder’s obligation to accept Purchase Notices and Intraday VWAP Purchase Notices that are timely delivered by us under the Purchase Agreement and to purchase shares of our Class A Common Stock in Purchases and Intraday VWAP Purchases under the Purchase Agreement, are subject to (i) the initial satisfaction, at the Commencement, and (ii) the satisfaction, at the applicable “VWAP Purchase Commencement Time” or “Purchase Condition Satisfaction Time” (as such terms are defined in the Purchase Agreement) on the applicable Purchase Date for each VWAP Purchase or Intraday VWAP Purchase, after the Commencement Date, of the conditions precedent thereto set forth in the Purchase Agreement, all of which are entirely outside of the Selling Stockholder’s control, which conditions include the following:

14

Termination of the Purchase Agreement

Unless earlier terminated as provided in the Purchase Agreement, the Purchase Agreement will terminate automatically on the earliest to occur of:

15

We have the right to terminate the Purchase Agreement at any time after Commencement Date, at no cost or penalty, upon ten trading days’ prior written notice to the Selling Stockholder. We and the Selling Stockholder may also terminate the Purchase Agreement at any time by mutual written consent.

The Selling Stockholder also has the right to terminate the Purchase Agreement upon ten trading days’ prior written notice to us, but only upon the occurrence of certain events, including:

No termination of the Purchase Agreement by us or by the Selling Stockholder will become effective prior to the fifth trading day immediately following the date on which any pending (or not fully settled) VWAP Purchase or Intraday VWAP Purchase has been fully settled in accordance with the terms and conditions of the Purchase Agreement, and no termination will affect any of our respective rights and obligations under the Purchase Agreement with respect to any pending (or not fully settled) VWAP Purchase, any pending Intraday VWAP Purchase, the Initial Commitment Shares, the Additional Commitment Shares, and any fees and disbursements of the Selling Stockholder’s legal counsel in connection with the transactions contemplated by the Purchase Agreement and the Registration Rights Agreement, and both we and the Selling Stockholder have agreed to complete our respective obligations with respect to any such pending (or not fully settled) VWAP

16

Purchase or Intraday VWAP Purchase under the Purchase Agreement. Furthermore, no termination of the Purchase Agreement will affect the Registration Rights Agreement, which will survive any termination of the Purchase Agreement.

No Short-Selling or Hedging by the Selling Stockholder

The Selling Stockholder has agreed not to engage in or effect, directly or indirectly, for its own principal account or for the principal account of its sole member, any of its or its sole member’s respective officers, or any entity managed or controlled by it or its sole member, any (i) “short sale” (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of the Class A Common Stock or (ii) hedging transaction, which establishes a net short position with respect to the Class A Common Stock, during the term of the Purchase Agreement.

Prohibition on Variable Rate Transactions

Subject to specified exceptions included in the Purchase Agreement, we are limited in our ability to enter into specified “Variable Rate Transactions” (as such term is defined in the Purchase Agreement) during the term of the Purchase Agreement. Such transactions include, among others, the issuance of convertible securities with a conversion or exercise price that is based upon or varies with the trading price of our Class A Common Stock after the date of issuance, or our effecting or entry into any agreement for an “equity line of credit” or other substantially similar continuous offering with a third party (other than with the Selling Stockholder) whereby we may offer, issue, or sell Class A Common Stock or any securities exercisable, exchangeable, or convertible into Class A Common Stock at a future-determined price.

Effect of Sales of Our Class A Common Stock Under the Purchase Agreement on Our Stockholders

All shares of Class A Common Stock that may be issued or sold by us to the Selling Stockholder under the Purchase Agreement that are being registered under the Securities Act for resale by the Selling Stockholder in this offering are expected to be freely tradable. The shares of Class A Common Stock being registered for resale in this offering may be issued and sold by us to the Selling Stockholder from time to time at our discretion over a period of up to 24 months commencing on the Commencement Date. The resale by the Selling Stockholder of a significant number of shares registered for resale in this offering at any given time, or the perception that these sales may occur, could cause the market price of our Class A Common Stock to decline and to be highly volatile. Sales of our Class A Common Stock, if any, to the Selling Stockholder under the Purchase Agreement will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to the Selling Stockholder all, some or none of the shares of our Class A Common Stock that may be available for us to sell to the Selling Stockholder pursuant to the Purchase Agreement.

If and when we do elect to sell shares of our Class A Common Stock to the Selling Stockholder pursuant to the Purchase Agreement, after the Selling Stockholder has acquired such shares, the Selling Stockholder may resell all, some or none of such shares at any time or from time to time in its discretion and at different prices. As a result, investors who purchase shares from the Selling Stockholder in this offering at different times will likely pay different prices for those shares, and so may experience different levels of dilution, and in some cases, substantial dilution and different outcomes in their investment results. Investors may experience a decline in the value of the shares they purchase from the Selling Stockholder in this offering as a result of future sales made by us to the Selling Stockholder at prices lower than the prices such investors paid for their shares in this offering. In addition, if we sell a substantial number of shares to the Selling Stockholder under the Purchase Agreement, or if investors expect that we will do so, the actual sales of shares or the mere existence of our arrangement with the Selling Stockholder may make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales.

Because the purchase price per share to be paid by the Selling Stockholder for the shares of Class A Common Stock that we may elect to sell to the Selling Stockholder under the Purchase Agreement, if any, will

17

fluctuate based on the market prices of our Class A Common Stock during the applicable VWAP Purchase Valuation Period for each VWAP Purchase, or during the applicable Intraday Purchase Valuation Period for each Intraday VWAP Purchase, in each case made pursuant to the Purchase Agreement, if any, as of the date of this prospectus it is not possible for us to predict the number of shares of Class A Common Stock that we will sell to the Selling Stockholder under the Purchase Agreement, the actual purchase price per share to be paid by the Selling Stockholder for those shares, or the actual gross proceeds to be raised by us from those sales, if any. As of April May 3, 2023, there were 215,286,444 shares of our Class A Common Stock outstanding, of which 183,367,081 shares were held by non-affiliates. Although the Purchase Agreement provides that we may sell up to an aggregate of $100,000,000 of our Class A Common Stock to the Selling Stockholder, only 33,640,902 shares of our Class A Common Stock are being registered for resale under the registration statement that includes this prospectus. If all of the 33,640,902 shares offered for resale by the Selling Stockholder under this prospectus were issued and outstanding as of May 3, 2023, such shares would represent approximately 13.5% of the total number of shares of our Class A Common Stock outstanding (including the shares of Class A Common Stock offered for resale) and approximately 15.5% of the total number of outstanding shares of Class A Common Stock held by non-affiliates (including the shares of Class A Common Stock offered for resale).

If it becomes necessary for us to issue and sell to the Selling Stockholder under the Purchase Agreement more shares than are being registered for resale under this prospectus in order to receive aggregate gross proceeds equal to $100,000,000 under the Purchase Agreement, we must first file with the SEC one or more additional registration statements to register under the Securities Act the resale by the Selling Stockholder of any such additional shares of our Class A Common Stock we wish to sell from time to time under the Purchase Agreement, which the SEC must declare effective, in each case, before we may elect to sell any additional shares of our Class A Common Stock to the Selling Stockholder under the Purchase Agreement. Additionally, under the applicable rules of NASDAQ, in no event may we issue to the Selling Stockholder under the Purchase Agreement more than the Exchange Cap (as such term is defined in the Purchase Agreement), unless we first (i) obtain stockholder approval to issue shares of Class A Common Stock in excess of the Exchange Cap under the Purchase Agreement in accordance with applicable NASDAQ rules and (ii) file with the SEC one or more additional registration statements to register under the Securities Act the resale by the Selling Stockholder of any such additional shares of our Class A Common Stock we wish to sell from time to time under the Purchase Agreement, which the SEC must declare effective, in each case, before we may elect to sell any additional shares of our Class A Common Stock to the Selling Stockholder under the Purchase Agreement. The number of shares of our Class A Common Stock ultimately offered for sale by the Selling Stockholder is dependent upon the number of shares of our Class A Common Stock, if any, we ultimately sell to the Selling Stockholder under the Purchase Agreement. In addition, the Selling Stockholder will not be required to purchase any shares of Class A Common Stock if such sale would result in the Selling Stockholder’s beneficial ownership exceeding the Beneficial Ownership Limitation, which is defined in the Purchase Agreement as 4.99% of the outstanding shares of Class A Common Stock. Our inability to access a portion or the full amount available under the Purchase Agreement, in the absence of any other financing sources, could have a material adverse effect on our business or results of operation.

The issuance of our Class A Common Stock to the Selling Stockholder pursuant to the Purchase Agreement will not affect the rights or privileges of our existing stockholders, except that the economic and voting interests of each of our existing stockholders will be diluted. Although the number of shares of our Class A Common Stock that our existing stockholders own will not decrease, the shares of our Class A Common Stock owned by our existing stockholders will represent a smaller percentage of our total outstanding shares of our Class A Common Stock after any such issuance.

The following table sets forth the amount of gross proceeds we would receive from the Selling Stockholder from our sale of shares of Class A Common Stock to the Selling Stockholder under the Purchase Agreement at varying purchase prices:

19

USE OF PROCEEDS

This prospectus relates to the offer and resale of up to 33,640,902 shares of Class A Common Stock by the Selling Stockholder, which consist of 33,281,805 shares of Class A Common Stock that we may, in our discretion, elect to issue and sell to the Selling Stockholder, from time to time after the Commencement Date, pursuant to the Purchase Agreement, in which the Selling Stockholder has committed, subject to satisfaction of specified conditions, to purchase from us, at our direction, up to $100,000,000 of our Class A Common Stock, subject to limitations specified in the Purchase Agreement.

We are not selling any shares of Class A Common Stock being offered by this prospectus and will not receive any of the proceeds from the sale of such shares by the Selling Stockholder. However, we may receive up to $100,000,000 in aggregate gross proceeds from sales of our Class A Common Stock to the Selling Stockholder that we may, in our discretion, elect to make, from time to time after the Commencement Date, pursuant to the Purchase Agreement.

We intend that any funds we receive from our sale of shares to the Selling Stockholder under the Purchase Agreement will be used for general corporate purposes. We will have broad discretion in the way that we use these proceeds.

The Selling Stockholder will pay any underwriting discounts and commissions and expenses incurred by it for brokerage, accounting, tax or legal services or any other expenses incurred by it in disposing of the Class A Common Stock. We will bear all other costs, fees and expenses incurred in effecting the registration of the Class A Common Stock covered by this prospectus, including, without limitation, all registration and filing fees and fees and expenses of our counsel and our accountants.

DILUTION

Our net tangible book value as of March 31, 2023, was approximately $33.7 million, or $0.16 per share. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities excluding intangible liabilities, by the number of shares of our Class A common stock outstanding as of March 31, 2023. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by the Selling Stockholder of shares of our Class A Common Stock in this offering and the net tangible book value per share of our Class A Common Stock immediately after this offering.

After giving effect to the assumed sale of 33,281,805 shares of our Class A common stock in this offering at an assumed offering price of $0.3816 per share, the last reported sale price of our Class A common stock on NYSE on May 3, 2023, and after deducting commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of March 31, 2023 would have been approximately $45.6 million, or $0.18 per share. This would represent an immediate increase in net tangible book value of less than $0.02 per share to existing stockholders and immediate dilution of $0.02 per share to investors purchasing our Class A common stock in this offering at the assumed public offering price. The following table illustrates this dilution on a per share basis:

The table above assumes for illustrative purposes that an aggregate of 33,281,805 shares of our Class A common stock are sold during the terms of the Purchase Agreement at a price of $0.3816 per share, the last reported sale price of our Class A common stock on NASDAQ on May 3, 2023, for aggregate gross proceeds of $11.9 million. Pursuant to the Purchase Agreement, the shares are being sold from time to time at various prices. An increase of $0.10 per share in the price at which the shares are sold from the assumed offering price of $0.3816 per share shown in the table above, assuming 33,281,805 shares of our Class A Common Stock registered under this prospectus is sold at that price, would increase our adjusted net tangible book value per share after the offering to $0.20 per share and would increase the dilution in net tangible book value per share to new investors in this offering to $0.04 per share, after deducting commissions and estimated offering expenses payable by us. A decrease of $0.10 per share in the price at which the shares are sold from the assumed offering price of $0.3816 per share shown in the table above, assuming all 33,281,805 shares of our Class A common stock registered under this prospectus is sold at that price, would decrease our adjusted net tangible book value per share after the offering to $0.17 per share and would decrease the dilution in net tangible book value per share to new investors in this offering to $0.01 per share, after deducting commissions and estimated offering expenses payable by us. This information is supplied for illustrative purposes only and may differ based on the actual offering price and the actual number of shares offered.

The above discussion and table are based on 215,286,444 shares outstanding as of March 31, 2023, and exclude as of that date:

SELLING STOCKHOLDER

This prospectus relates to the offer and sale by the Selling Stockholder of up to 33,640,902 shares of Class A Common Stock that have been and may be issued by us to the Selling Stockholder under the Purchase Agreement. For additional information regarding the shares of Class A Common Stock included in this prospectus, see the section titled “The Committed Equity Financing” above. We are registering the shares of Class A Common Stock included in this prospectus pursuant to the provisions of the Registration Rights Agreement we entered into with the Selling Stockholder on August 2, 2022, in order to permit the Selling Stockholder to offer the shares included in this prospectus for resale from time to time. Except for the transactions contemplated by the Purchase Agreement and the Registration Rights Agreement, the Selling Stockholder has not had any material relationship with us within the past three years.

The table below presents information regarding the Selling Stockholder and the shares of Class A Common Stock that may be resold by the Selling Stockholder from time to time under this prospectus. This table is prepared based on information supplied to us by the Selling Stockholder, and reflects holdings as of May 3, 2023. The number of shares in the column “Maximum Number of Shares of Class A Common Stock to be Offered Pursuant to this Prospectus” represents all of the shares of Class A Common Stock being offered for resale by the Selling Stockholder under this prospectus. The Selling Stockholder may sell some, all or none of the shares being offered for resale in this offering. We do not know how long the Selling Stockholder will hold the shares before selling them, and, except as set forth in the section titled “Plan of Distribution (Conflicts of Interest)” in this prospectus, we are not aware of any existing arrangements between the Selling Stockholder and any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares of our Class A Common Stock being offered for resale by this prospectus.

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act, and includes shares of Class A Common Stock with respect to which the Selling Stockholder has sole or shared voting and investment power. The percentage of shares of Class A Common Stock beneficially owned by the Selling Stockholder prior to the offering shown in the table below is based on an aggregate of 215,286,444 shares of our Class A Common Stock outstanding on May 3, 2023. Because the purchase price to be paid by the Selling Stockholder for shares of Class A Common Stock, if any, that we may elect to sell to the Selling Stockholder in one or more VWAP Purchases and one or more Intraday VWAP Purchases from time to time under the Purchase Agreement will be determined on the applicable Purchase Dates therefor, the actual number of shares of Class A Common Stock that we may sell to the Selling Stockholder under the Purchase Agreement may be fewer than the number of shares being offered for resale under this prospectus. The fourth column assumes the resale by the Selling Stockholder of all of the shares of Class A Common Stock being offered for resale pursuant to this prospectus.

PLAN OF DISTRIBUTION (CONFLICT OF INTEREST)

The shares of Class A Common Stock offered by this prospectus are being offered by the Selling Stockholder, B. Riley Principal Capital II, LLC. The shares may be sold or distributed from time to time by the Selling Stockholder directly to one or more purchasers or through brokers, dealers, or underwriters who may act solely as agents at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. The sale of the shares of our Class A Common Stock offered by this prospectus could be effected in one or more of the following methods:

In order to comply with the securities laws of certain states, if applicable, the shares may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the shares may not be sold unless they have been registered or qualified for sale in the state or an exemption from the state’s registration or qualification requirement is available and complied with.

The Selling Stockholder is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act.

The Selling Stockholder has informed us that it presently anticipates using, but is not required to use, B. Riley Securities, Inc. (“BRS”), a registered broker-dealer and FINRA member and an affiliate of the Selling Stockholder, as a broker to effectuate resales, if any, of our Class A Common Stock that it may acquire from us pursuant to the Purchase Agreement, and that it may also engage one or more other registered broker-dealers to effectuate resales, if any, of such Class A Common Stock that it may acquire from us. Such resales will be made at prices and at terms then prevailing or at prices related to the then current market price. Each such registered broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act. The Selling Stockholder has informed us that each such broker-dealer it engages to effectuate resales of our Class A Common Stock on its behalf, excluding BRS, may receive commissions from the Selling Stockholder for executing such resales for the Selling Stockholder and, if so, such commissions will not exceed customary brokerage commissions.

The Selling Stockholder is an affiliate of BRS. BRS is a registered broker-dealer and FINRA member, which may act as an executing broker that will effectuate resales of our Class A Common Stock that have been and may be acquired by the Selling Stockholder from us pursuant to the Purchase Agreement to the public in this offering. Because the Selling Stockholder will receive all the net proceeds from such resales of our Class A Common Stock made to the public through BRS, BRS is deemed to have a “conflict of interest” within the meaning of FINRA Rule 5121. Consequently, this offering will be conducted in compliance with the provisions of FINRA Rule 5121. In accordance with FINRA Rule 5121, BRS is not permitted to sell shares of our Class A Common Stock in this offering to an account over which it exercises discretionary authority without the prior specific written approval of the account holder.

Except as set forth above, we know of no existing arrangements between the Selling Stockholder and any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares of our Class A Common Stock offered by this prospectus.

25

Brokers, dealers, underwriters or agents participating in the distribution of the shares of our Class A Common Stock offered by this prospectus may receive compensation in the form of commissions, discounts, or concessions from the purchasers, for whom the broker-dealers may act as agent, of the shares sold by the Selling Stockholder through this prospectus. The compensation paid to any such particular broker-dealer by any such purchasers of shares of our Class A Common Stock sold by the Selling Stockholder may be less than or in excess of customary commissions. Neither we nor the Selling Stockholder can presently estimate the amount of compensation that any agent will receive from any purchasers of shares of our Class A Common Stock sold by the Selling Stockholder.

We may from time to time file with the SEC one or more supplements to this prospectus or amendments to the registration statement of which this prospectus forms a part to amend, supplement or update information contained in this prospectus, including, if and when required under the Securities Act, to disclose certain information relating to a particular sale of shares offered by this prospectus by the Selling Stockholder, including with respect to any compensation paid or payable by the Selling Stockholder to any brokers, dealers, underwriters or agents that participate in the distribution of such shares by the Selling Stockholder, and any other related information required to be disclosed under the Securities Act.

We will pay the expenses incident to the registration under the Securities Act of the offer and sale of the shares of our Class A Common Stock covered by this prospectus by the Selling Stockholder.

As consideration for its irrevocable commitment to purchase our Class A Common Stock under the Purchase Agreement, we have agreed to issue to the Selling Stockholder up to an aggregate of 718,195 shares of our Class A Common Stock as Commitment Shares, which Commitment Shares have a total aggregate value equal to 1.0% of the Selling Stockholder’s $100,000,000 total dollar amount purchase commitment under the Purchase Agreement (assuming a purchase price of $1.3924 per Commitment Share, representing the volume weighted average price per share of our Class A Common Stock for the five-consecutive trading day period ending on the date of the Purchase Agreement). Of such 718,195 aggregate Commitment Shares, we issued 359,098 shares as Initial Commitment Shares upon execution of the Purchase Agreement and the Registration Rights Agreement, and we will issue up to 359,097 shares as Additional Commitment Shares in two tranches, the first of which we will issue to the Selling Stockholder when we have received aggregate gross proceeds of $25,000,000 from sales of our Class A Common Stock to the Selling Stockholder under the Purchase Agreement (if any), and the second of which we will issue to the Selling Stockholder when we have received aggregate gross proceeds of $50,000,000 from sales of our Class A Common Stock to the Selling Stockholder under the Purchase Agreement (if any). In accordance with FINRA Rule 5110, the Commitment Shares are deemed to be underwriting compensation in connection with sales of our Class A Common Stock by the Selling Stockholder to the public. In addition, we have reimbursed the Selling Stockholder for the reasonable legal fees and disbursements of the Selling Stockholder’s legal counsel in the amount of $125,000 in conjunction with the execution of the Purchase Agreement and Registration Rights Agreement. We have also agreed to pay the Selling Stockholder up to $7,500 per fiscal quarter in reasonable legal fees and disbursements of the Selling Stockholder’s legal counsel, in each case in connection with the transactions contemplated by the Purchase Agreement and the Registration Rights Agreement. In accordance with FINRA Rule 5110, these reimbursed fees and expenses are deemed to be underwriting compensation in connection with sales of our Class A Common Stock by the Selling Stockholder to the public.

We also have agreed to indemnify the Selling Stockholder and certain other persons against certain liabilities in connection with the offering of shares of our Class A Common Stock offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. The Selling Stockholder has agreed to indemnify us against liabilities under the Securities Act that may arise from certain written information furnished to us by the Selling Stockholder specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons, we have been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is therefore, unenforceable.

26

We estimate that the total expenses for the offering will be approximately $611,062.

The Selling Stockholder has represented to us that at no time prior to the date of the Purchase Agreement has the Selling Stockholder, its officers, its sole member, or any entity managed or controlled by the Selling Stockholder or its sole member, engaged in or effected, in any manner whatsoever, directly or indirectly, for its own account or for the account of any of its affiliates, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of our Class A Common Stock or any hedging transaction, which establishes a net short position with respect to our Class A Common Stock. The Selling Stockholder has agreed that during the term of the Purchase Agreement, none of the Selling Stockholder, its officers, its sole member, or any entity managed or controlled by the Selling Stockholder or its sole member, will enter into or effect, directly or indirectly, any of the foregoing transactions for its own account or for the account of any other such person or entity.

We have advised the Selling Stockholder that it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes the Selling Stockholder, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

Common Stock

Class A Common Stock

Holders of Class A Common Stock are entitled to cast one vote per share of Class A Common Stock. Generally, holders of all classes of Common Stock vote together as a single class, and an action is approved by stockholders if the number of votes cast in favor of the action exceeds the number of votes cast in opposition to the action, while directors are elected by a plurality of the votes cast in contested elections. Holders of Class A Common Stock are not entitled to cumulate their votes in the election of directors.

Dividend Rights

Holders of Class A Common Stock share ratably (based on the number of shares of Class A Common Stock held) if and when any dividend is declared by the Board out of funds legally available therefor, subject to restrictions, whether statutory or contractual (including with respect to any outstanding indebtedness), on the declaration and payment of dividends and to any restrictions on the payment of dividends imposed by the terms of any outstanding preferred stock or any class or series of stock having a preference over, or the right to participate with, the Class A Common Stock with respect to the payment of dividends.

Liquidation, Dissolution and Winding Up

On the liquidation, dissolution, distribution of assets or winding up of the Company, each holder of Class A Common Stock is entitled, pro rata on a per share basis, to all assets of the Company of whatever kind available for distribution to the holders of Common Stock, subject to the designations, preferences, limitations, restrictions and relative rights of any other class or series of preferred stock of the Company then outstanding.

Other Matters

Holders of shares of Class A common stock do not have subscription, redemption or conversion rights. All the outstanding shares of Class A common stock are validly issued, fully paid and non-assessable.

28

Class B Common Stock

Voting Rights

Holders of Class B Common Stock are entitled to cast 10 votes per share of Class B Common Stock. Generally, holders of all classes of Common Stock vote together as a single class, and an action is approved by stockholders if the number of votes cast in favor of the action exceeds the number of votes cast in opposition to the action, while directors are elected by a plurality of the votes cast in contested elections. Holders of Class B Common Stock are not entitled to cumulate their votes in the election of directors.

Dividend Rights

Holders of Class B Common Stock share ratably (based on the number of shares of Class B Common Stock held) if and when any dividend is declared by the Board out of funds legally available therefor, subject to restrictions, whether statutory or contractual (including with respect to any outstanding indebtedness), on the declaration and payment of dividends and to any restrictions on the payment of dividends imposed by the terms of any outstanding preferred stock or any class or series of stock having a preference over, or the right to participate with, the Class B Common Stock with respect to the payment of dividends.

Optional Conversion Rights

Holders of Class B Common Stock have the right to convert shares of their Class B Common Stock into fully paid and non-assessable shares of Class A Common Stock, on a one-to-one basis, at the option of the holder at any time upon written notice to the Company.

Mandatory Conversion Rights

Holders of Class B Common Stock shall have their Class B Common Stock automatically converted into Class A Common Stock, on a one-to-one basis, upon the occurrence of any of the events described below:

Liquidation Rights

On the liquidation, dissolution, distribution of assets or winding up of the Company, each holder of Class B Common Stock will be entitled, pro rata on a per share basis, to all assets of the Company of whatever kind available for distribution to the holders of Common Stock, subject to the designations, preferences, limitations, restrictions and relative rights of any other class or series of preferred stock of the Company then outstanding.

29

Preferred Stock

Our Second Amended and Restated Certificate of Incorporation provides that the Board has the authority, without action by the stockholders, to designate and issue shares of preferred stock in one or more classes or series, and the number of shares constituting any such class or series, and to fix the voting powers, designations, preferences, limitations, restrictions and relative rights of each class or series of preferred stock, including, without limitation, dividend rights, dividend rates, conversion rights, exchange rights, voting rights, rights and terms of redemption, dissolution preferences, and treatment in the case of a merger, business combination transaction, or sale of the Company’s assets, which rights may be greater than the rights of the holders of the Common Stock. There are no shares of preferred stock outstanding immediately upon consummation of the Business Combination.

At the Effective Time, by virtue of the merger of Merger Sub with and into Astra, each share of Astra Class A common stock and Astra Series A Preferred Stock, Astra Series B Preferred Stock and Astra Series C Preferred Stock was converted into the right to receive the applicable Per Share Merger Consideration and, as a result, there are no shares of preferred stock currently outstanding.

The purpose of authorizing the Board to issue preferred stock and determine the rights and preferences of any classes or series of preferred stock is to eliminate delays associated with a stockholder vote on specific issuances. The simplified issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of the outstanding voting stock. Additionally, the issuance of preferred stock may adversely affect the holders of Class A Common Stock by restricting dividends on the Class A Common Stock, diluting the voting power of the Class A Common Stock or subordinating the dividend or liquidation rights of the Class A Common Stock. As a result of these or other factors, the issuance of preferred stock could have an adverse impact on the market price of the Class A Common Stock.

Certain Anti-Takeover Provisions of Delaware Law and our Second Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

Certain provisions of our Second Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, and laws of the State of Delaware, where the Company is incorporated, may discourage or make more difficult a takeover attempt that a stockholder might consider in his or her best interest. These provisions may also adversely affect prevailing market prices for the Class A Common Stock and the Class B Common Stock. The Company believes that the benefits of increased protection give the Company the potential ability to negotiate with the proponent of an unsolicited proposal to acquire or restructure the Company and outweigh the disadvantage of discouraging those proposals because negotiation of the proposals could result in an improvement of their terms.

Authorized but Unissued Shares

Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of NASDAQ, which would apply if and so long as the Class A Common Stock remains listed on NASDAQ, require stockholder approval of certain issuances equal to exceeding 20% of the then outstanding voting power or then outstanding number of shares of Common Stock. Additional shares that may be used in the future may be issued for a variety of corporate purposes, including future public offerings, to raise additional capital, or to facilitate acquisitions. The existence of authorized but unissued and unreserved Common Stock and preferred stock could make more difficult or discourage an attempt to obtain control of the Company by means of a proxy contest, tender offer, merger, or otherwise.

30

Dual Class Stock

As described above, Our Second Amended and Restated Certificate of Incorporation provides for a dual class common stock structure which provides the Astra Founders with the ability to control the outcome of matters requiring stockholder approval, even though he owns significantly less than a majority of the shares of outstanding Class A Common Stock, including the election of directors and significant corporate transactions, such as a merger or other sale of the Company or its assets.

Number of Directors

Our Second Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provide that, subject to any rights of holders of preferred stock to elect additional directors under specified circumstances, the number of directors may be fixed from time to time pursuant to a resolution adopted by the Board; providing, however, that unless approved by (i) if before the first date on which the issued and outstanding shares of Class B Common Stock represents less than 50% of the total voting power of the then outstanding shares of capital stock that would then be entitled to vote in the election of directors at an annual meeting of stockholders, the holders of a majority in voting power of the shares of capital stock of the Company that would then be entitled to vote in the election of directors at an annual meeting or by written consent, or (ii) if after the first date on which the issued and outstanding shares of Class B Common Stock represents less than 50% of the total voting power of the then outstanding shares of capital stock that would then be entitled to vote in the election of directors at an annual meeting of stockholders, by the holders of two-thirds (2/3rds) of the voting power of the shares of capital stock that would then be entitled to vote in the election of directors at an annual meeting of stockholders, the number of directors may not exceed seven. The initial number of directors will be set at seven.

Requirements for Advance Notification of Stockholder Meetings, Nominations and Proposals

The Amended and Restated Bylaws establish advance notice procedures with respect to stockholder proposals and 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 to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide the Company with certain information. Generally, to be timely, a stockholder’s notice must be received at the Company’s principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary of the immediately preceding annual meeting of stockholders. The Amended and Restated Bylaws also specify requirements as to the form and content of a stockholder’s notice. The Amended and Restated Bylaws allow the chairman of the meeting at a meeting of the stockholders to adopt rules and regulations for the conduct of meetings 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 the Company.

Limitations on Stockholder Action by Written Consent

Our Second Amended and Restated Certificate of Incorporation provides that, subject to the terms of any series of preferred stock, any action required or permitted to be taken by the stockholders must be effected at an annual or special meeting of the stockholders and may not be effected by written consent in lieu of a meeting.

Amendment of the Second Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

The DGCL provides generally that the affirmative vote of a majority of the outstanding shares entitled to vote thereon, voting together a single class, is required to amend a corporation’s certificate of incorporation, unless the certificate of incorporation requires a greater percentage.

31

The Second Amended and Restated Certificate of Incorporation provides that it may be amended by the Company in the manners provided therein or prescribed by statute. The Second Amended and Restated Certificate of Incorporation provides that the affirmative vote of the holders of a majority of the voting power of the then-outstanding shares of capital stock of the Company entitled to vote generally in the election of directors, voting together as a single class, will be required to amend or repeal, or adopt any provision of the Charter providing for the capital stock of the Company, amendment of the charter, amendment of the bylaws, board of directors, election of directors, limitation of director liability, indemnification and special meetings of the stockholders.

If any of the Class B Common Stock shares are outstanding, the Company will not, without the prior affirmative vote of the holders of two-thirds (2/3rds) of the outstanding shares of Class B Common Stock, voting as a separate class, in addition to any other vote required by applicable law or the Second Amended and Restated Certificate of Incorporation, directly or indirectly, amend, alter, change, repeal, or adopt any provision of the Second Amended and Restated Certificate of Incorporation (1) in a manner that is inconsistent with, or otherwise alters or changes, any of the voting, conversion, dividend, or liquidation provisions of the shares of Class B Common Stock or other rights, powers, preferences, or privileges of the shares of Class B Common Stock, (2) to provide for each share of Class A Common Stock to have more than one vote per share or any rights to a separate class vote of the holders of shares of Class A Common Stock other than as provided in the Second Amended and Restated Certificate of Incorporation or required by the DGCL, or (3) to otherwise adversely impact or affect the rights, powers, preferences, or privileges of the shares of Class B Common Stock.

If any of the shares of Class A Common Stock are outstanding, the Company will not, without the prior affirmative vote of the holders of two-thirds (2/3rds) of the outstanding shares of Class A Common Stock, voting as a separate class, in addition to any other vote required by applicable law or the Second Amended and Restated Certificate of Incorporation, directly or indirectly, amend, alter, change, repeal, or adopt any provision of the Second Amended and Restated Certificate of Incorporation (1) in a manner that is inconsistent with, or otherwise alters or changes, any of the voting, conversion, dividend, or liquidation provisions of the shares of Class A Common Stock or other rights, powers, preferences, or privileges of the shares of Class A Common Stock or (2) to provide for each share of Class B Common Stock to have more than 10 votes per share or any rights to a separate class vote of the holders of shares of Class B Common Stock other than as provided in the Second Amended and Restated Certificate of Incorporation or required by the DGCL.

The Second Amended and Restated Certificate of Incorporation also provides that the Board shall have the power to adopt, amend, alter, or repeal the Amended and Restated Bylaws by the affirmative vote of a majority of the directors present at any regular or special meeting of the Board at which a quorum is present in any manner not inconsistent with the laws of the State of Delaware or the Second Amended and Restated Certificate of Incorporation. The stockholders of Amended and Restated are prohibited from adopting, amending, altering, or repealing the Amended and Restated Bylaws, or to adopt any provision inconsistent with the Amended and Restated Bylaws, unless such action is approved, in addition to any other vote required by the Second Amended and Restated Certificate of Incorporation, by the Requisite Stockholder Consent.

Business Combinations

Under Section 203 of the DGCL, a corporation will not be permitted to engage in a business combination with any interested stockholder for a period of three years following the time that such interested stockholder became an interested stockholder, unless:

32

Generally, a “business combination” includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years owned, 15% or more of the Company’s outstanding voting stock. For purposes of this section only, “voting stock” has the meaning given to it in Section 203 of the DGCL.

Since the Company has not opted out of Section 203 of the DGCL, it will apply to the Company. As a result, this provision will make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with the Company for a three-year period. This provision may encourage companies interested in acquiring the Company to negotiate in advance with the Board because the stockholder approval requirement would be avoided if the Board approves either the business combination or the transaction which results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing changes in the Board and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

Cumulative Voting

Under Delaware law, the right to vote cumulatively does not exist unless the charter specifically authorizes cumulative voting. The Second Amended and Restated Certificate of Incorporation does not authorize cumulative voting.

Limitations on Liability and Indemnification of Officers and Directors

The DGCL authorizes corporations to limit or eliminate the personal liability of directors of corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties, subject to certain exceptions. The Company’s Charter includes a provision that eliminates the personal liability of directors for damages for any breach of fiduciary duty as a director where, in civil proceedings, the person acted in good faith and in a manner that person reasonably believed to be in or not opposed to the best interests of the Company or, in criminal proceedings, where the person had no reasonable cause to believe that his or her conduct was unlawful.

The Amended and Restated Bylaws provide that the Company must indemnify and advance expenses to its directors and officers to the fullest extent authorized by the DGCL. The Company also is expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for its directors, officers, and certain employees for some liabilities. The Company believes 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 the Second Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws may discourage stockholders from bringing 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 the Company and its stockholders. In addition, your investment may be adversely affected to the extent the Company pays the costs of settlement and damage awards against directors and officer pursuant to these indemnification provisions.

33

Corporate Opportunities

The Second Amended and Restated Certificate of Incorporation provides for the renouncement by the Company of any interest or expectancy of the Company in, or being offered an opportunity to participate in any matter, transaction, or interest that is presented to, or acquired, created, or developed by, or which otherwise comes into possession of, any director of the Company who is not an employee or officer of the Company or any of its subsidiaries, unless such matter, transaction, or interest is presenting to, or acquired, created, or developed by, or otherwise comes into the possession of a director of the Company expressly and solely in that director’s capacity as a director of the Company.

Dissenters’ Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, the Company’s stockholders will 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 will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

Stockholders’ Derivative Actions

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