SELLING STOCKHOLDERS

On April 30, 2022, we entered into an investment agreement, or the Investment Agreement, with Antara Capital LP, on behalf of certain advised or managed funds and accounts, or Antara, pursuant to which we sold $200.0 million aggregate principal amount of 8.00% / 11.00% Convertible Senior PIK Toggle Notes due 2026, or the Notes, to the selling stockholders. The Notes were issued pursuant to an indenture, dated as of June 1, 2022, as supplemented by the first supplemental indenture dated as of April 3, 2023, by the second supplemental indenture dated April 10, 2023 and by the third supplemental indenture dated as of June 23, 2023, or as so supplemented, the 2022 Indenture, by and among us, the guarantors named therein, and U.S. Bank Trust Company, National Association, as trustee. On March 29, 2023, we entered into an exchange agreement, or the Exchange Agreement, with Antara and the guarantors named therein, pursuant to which Antara agreed to exchange $100.0 million aggregate principal amount of the Notes for $100.0 million of our 8.00% / 11.00% Series B Convertible Senior PIK Toggle Notes due 2026, or the Series B Notes. The Series B Notes were issued pursuant to an indenture, dated as of April 11, 2023, as supplemented by the first supplemental indenture dated as of June 23, 2023, or as so supplemented, the 2023 Indenture, by and among us, the guarantors named therein, and U.S. Bank Trust Company, National Association, as trustee. The Exchange closed on April 11, 2023. In addition, in June 2023, we issued $11.0 million aggregate principal amount of 8.00% / 8.00% Series C Convertible Senior PIK Toggle Notes due 2026, or the Series C Notes, in connection with obtaining consents from the holders of the Notes and the Series B Notes to release Romeo Power, Inc. as a guarantor of such Notes and Series B Notes. We can elect to pay interest on the Notes through cash or through payment in kind by an increase in the principal amount of the Notes, or PIK Interest.

We sold the Notes in a transaction exempt from the registration requirements of the Securities Act of 1933, or the Securities Act, and expect to rely on an exemption for any issuance of the shares of common stock issuable upon conversion of the Notes. Under the Investment Agreement, we have agreed to file the registration statement of which this prospectus is a part to register the resale of the shares issuable upon conversion of the Notes.

As of August 9, 2023, all Series B Notes and PIK interest payments on the Series B Notes were converted into an aggregate of 72,458,789 shares of common stock and issued to the selling stockholders.

The following table sets forth, as of August 18, 2023, the name of the selling stockholders, the maximum aggregate number of shares of common stock held by the selling stockholder underlying the Notes (including the shares of common stock issuable upon conversion of the maximum principal amount of Notes potentially issuable as PIK interest payments on the Notes and the additional shares that may be issued assuming the potential maximum “make-whole” adjustment to the initial conversion rate), the number of shares of common stock that may be sold by the selling stockholders under this prospectus and the number of shares of common stock that the selling stockholders will beneficially own after this offering.

The following table is based on information supplied to us by the selling stockholders. We have determined beneficial ownership in accordance with the rules of the SEC and the information is not necessarily indicative of beneficial ownership for any other purpose. Unless otherwise indicated below, to our knowledge, the persons and entities named in the table have sole voting and sole investment power with respect to all securities that they beneficially own, subject to community property laws where applicable.

The selling stockholders may sell or otherwise transfer all, some or none of such shares in this offering. See “Plan of Distribution.”

(1) Represents the number of shares of common stock issued to, and as of August 18, 2023 held by, the selling stockholders upon conversion of the Series B Notes. The conversion rights under the Notes and the Series C Notes are not exercisable until February 28, 2026, other than during the five business days following a “measurement period” of ten consecutive trading days during which, on each trading day of such measurement period, a bid solicitation agent determines that the trading price of the Notes or the Series C Notes, as applicable, is less than 98% of the product of the last reported sale price of the common stock on such date for such Notes or Series C Notes, as applicable, and the number of shares into which such Notes or Series C Notes, as applicable, could be converted.

(2) Reflects 856,326,046 shares of our common stock outstanding as of August 15, 2023 and gives effect to the total number of shares of our common stock beneficially owned and offered hereby by such selling stockholder.

Represents the maximum number of shares of common stock that may be issuable upon conversion of the Notes, including shares issuable upon conversion of the maximum principal amount of Notes potentially issuable as PIK interest payments on the Notes and additional shares that may be issued assuming the potential maximum “make-whole” adjustment to the initial conversion rate of 114.3602 shares per $1,000 principal amount of Notes, and assumes that we elect physical settlement for all conversions of the Notes. The initial conversion rate is subject to adjustment under certain circumstances described in the 2022 Indenture. As a result, the maximum number of shares of common stock issuable upon conversion of the Notes may increase or decrease in the future. Selling stockholders will receive cash in lieu of any fractional share of common stock issuable upon conversion of the Notes.

(4) Assumes that all shares of common stock being registered under the registration statement of which this prospectus forms a part are sold in this offering, and that such selling stockholder does not acquire additional shares of common stock after the date of this prospectus and prior to completion of this offering.

Antara Capital Fund GP LLC, a Delaware limited liability company, serves as the general partner of the Antara Funds. Each of the Antara Funds is an exempted company incorporated under the laws of the Cayman Islands. Himanshu Gulati is the Managing Member of Investment Manager and, accordingly, may be deemed to have voting and dispositive power with respect to the shares of common stock issuable upon the conversion of the Notes held by the Antara Funds.

We will not receive any of the proceeds from the sale of shares by the selling stockholders.

The aggregate proceeds to the selling stockholders will be the purchase price of the shares less any discounts and commissions borne by the selling stockholders.

Once issued and upon effectiveness of the registration statement of which this prospectus is a part, the shares of our common stock beneficially owned by the selling stockholder covered by this prospectus may be offered and sold from time to time by the selling stockholders. The term “selling stockholders” includes donees, pledgees, transferees or other successors-in-interest selling our common stock or interests in our common stock received after the date of this prospectus from a registered stockholder as a gift, pledge, partnership, limited liability company or other entity distribution or other transfer, and may, or may not, elect to sell or transfer their shares of our common stock or interests in our common stock covered by this prospectus, as and to the extent they may determine. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. The selling stockholders reserve the right to accept and, together with their agents, to reject, any proposed purchase of shares to be made directly or through agents. The selling stockholders and any permitted transferees may sell or transfer their shares of our common stock offered by this prospectus on any stock exchange, market or trading facility on which the shares of our common stock are traded or in private transactions. These sales may be at a fixed price or varying prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to prevailing market prices or at negotiated prices. The shares of our common stock may be offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate.

The selling stockholders may use any one or more of the following methods when selling the shares of our common stock offered by this prospectus:

• purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

• ordinary brokerage transactions and transactions in which the broker solicits purchasers;

• block trades in which the broker-dealer so engaged will attempt to sell the shares of our common stock as agent but may position and resell a portion of the block as principal to facilitate the transaction;

• an over-the-counter distribution in accordance with the rules of the applicable exchange;

• through trading plans entered into by the selling stockholders pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, or the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their shares of common stock on the basis of parameters described in such trading plans;

• through one or more underwritten offerings on a firm commitment or best efforts basis;

• settlement of short sales entered into after the date of this prospectus;

• agreements with broker-dealers to sell a specified number of the shares of our common stock at a stipulated price per share;

• in “at the market” offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales

made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

• directly to purchasers, including through a specific bidding, auction or other process or in privately negotiated transactions;

• through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

• through a combination of any of the above methods of sale; or

• any other method permitted pursuant to applicable law.

The selling stockholders may also sell the shares of our common stock under Rule 144 under the Securities Act, if available, or in other transactions exempt from registration, rather than under this prospectus.

In addition, the selling stockholders may elect to make an in-kind distribution of the shares of our common stock 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 the registration statement of which this prospectus is a part. 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 shares of our common stock acquired in the distribution.

The selling stockholders 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. Upon being notified by the selling stockholders that a donee, pledgee, transferee, other successor- in-interest intends to sell the shares of our common stock, we will, to the extent required, promptly file a supplement to this prospectus to name specifically such person as a selling stockholder.

There can be no assurance that the selling stockholders will sell all or any of the shares of our common stock offered by this prospectus. In addition, the selling stockholders may also sell the shares under Rule 144 under the Securities Act, if available, or in other transactions exempt from registration, rather than under this prospectus. The selling stockholders have the sole and absolute discretion not to accept any purchase offer or make any sale of the shares if they deem the purchase price to be unsatisfactory at any particular time.

To the extent required, the shares of our common stock to be sold, the name of the selling stockholders, the respective purchase prices and public offering prices, the proceeds to be received from the sale, if any, and other material terms of the offering, the settlement of short sales entered into after the date of this prospectus, the names of any agents, dealer or underwriter, any applicable commissions or discounts or any other items constituting compensation from the selling stockholders 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 of which this prospectus is a part.

In connection with the sale of shares of our common stock, the selling stockholders 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 stockholders may also sell shares of our common stock short and deliver the shares of our common stock to close out their short positions, or loan or pledge the shares of our common stock to broker-dealers that in turn may sell the shares of our common stock. The selling stockholders 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 the shares of our common stock 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).

10

In order to facilitate the offering of the shares, any underwriters or agents, as the case may be, involved in the offering of such shares may engage in transactions that stabilize, maintain or otherwise affect the price of our securities. Specifically, the underwriters or agents, as the case may be, may over-allot in connection with the offering, creating a short position in our securities for their own account. In addition, to cover over-allotments or to stabilize the price of our securities, the underwriters or agents, as the case may be, may bid for, and purchase, such securities in the open market. Finally, in any offering of securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allotted to an underwriter or a broker-dealer for distributing such securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. The underwriters or agents, as the case may be, are not required to engage in these activities, and may end any of these activities at any time.

In offering the shares of our common stock covered by this prospectus, the selling stockholders and any underwriters, broker-dealers or agents who execute sales for the selling stockholder may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. Any discounts, commissions, concessions or profit they earn on any resale of those shares may be underwriting discounts and commissions under the Securities Act.

The selling stockholders may solicit offers to purchase the shares directly from, and may sell such Shares directly to, institutional investors or others. In this case, no underwriters or agents would be involved. The terms of any of those sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement.

It is possible that one or more underwriters may make a market in our securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for its securities.

The selling stockholders may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell the shares of our common stock covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by the selling stockholders or borrowed from the selling stockholder or others to settle those sales or to close out any related open borrowings of stock, and may use the shares of our common stock received from the selling stockholders in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, the selling stockholders may otherwise loan or pledge the shares of our common stock to a financial institution or other third party that in turn may sell the shares of our common stock short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

In effecting sales, broker-dealers or agents engaged by the selling stockholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the selling stockholders in amounts to be negotiated immediately prior to the sale.

In compliance with the guidelines of the Financial Industry Regulatory Authority, or FINRA, the aggregate maximum discount, commission, fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of the gross proceeds of any offering pursuant to this prospectus and any applicable prospectus supplement.

11

If at the time of any offering made under this prospectus a member of FINRA participating in the offering has a “conflict of interest” as defined in FINRA Rule 5121, or Rule 5121, that offering will be conducted in accordance with the relevant provisions of Rule 5121.

Underwriters, broker-dealers or agents may facilitate the marketing of an offering online directly or through one of their affiliates. In those cases, prospective investors may view offering terms and a prospectus online and, depending upon the particular underwriter, broker-dealer or agent, place orders online or through their financial advisors.

The underwriters, broker-dealers and agents may engage in transactions with us or the selling stockholders, or perform services for us or the selling stockholders, in the ordinary course of business.

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

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the securities may not simultaneously engage in market making activities with respect to our common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of our common stock by the selling stockholder or any other person. We will make copies of this prospectus available to the selling shareholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Pursuant to the Investment Agreement, we have agreed to indemnify the selling stockholders against certain liabilities, including certain liabilities under the Securities Act, the Exchange Act or other federal or state law.
