IMPLICATIONS OF BEING A SMALLER-REPORTING COMPANY

We are a smaller reporting company as defined in the Exchange Act. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as (i) the market value of our voting and non-voting common stock held by non-affiliates is less than $250 million measured on the last business day of our second fiscal quarter or (ii) our annual revenue is less than $100 million during the most recently completed fiscal year and the market value of our voting and non-voting common stock held by non-affiliates is less than $700 million measured on the last business day of our second fiscal quarter. Specifically, as a smaller reporting company, we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report and have reduced disclosure obligations regarding executive compensation, and if we are a smaller reporting company with less than $100 million in annual revenue, we would not be required to obtain an attestation report on internal control over financial reporting issued by our independent registered public accounting firm.

RISK FACTORS

An investment in our common stock involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described below, as well as the risks described under the caption "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2023 and in the other filings we make with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended, which we have incorporated herein by reference. The impacts of the contingencies contemplated by these risks could materially adversely affect our business, financial condition or results of operations. The risks described in these documents are not the only ones we face, but those that we consider to be material. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations and financial condition. Please also read carefully the section titled "Cautionary Note Regarding Forward-Looking Statements," where we describe additional uncertainties associated with our business and the forward-looking statements included or incorporated by reference in this prospectus.

Risks Related to this Offering and Ownership of Our Common Stock

The sale or issuance of our common stock to Lincoln Park may cause dilution and the sale of the shares of common stock acquired by Lincoln Park, or the perception that such sales may occur, could cause the price of our common stock to decrease.

On August 30, 2024, we entered into the Purchase Agreement with Lincoln Park, pursuant to which (i) we issued 600,000 shares to Lincoln Park as the Initial Commitment Shares, (ii) we have reserved and may issue 600,000 additional shares to Lincoln Park as the Additional Commitment Shares, in each case, as consideration for Lincoln Park's commitment to purchase shares of common stock under the Purchase Agreement, and (iii) Lincoln Park has committed to purchase up to $30,000,000 of our common stock.

The shares of our common stock that may be issued under the Purchase Agreement may be sold by us to Lincoln Park at our discretion from time to time over a 24-month period commencing after the satisfaction of certain conditions set forth in the Purchase Agreement, including that the SEC has declared effective the registration statement that includes this prospectus (such date on which all of such conditions are satisfied, the "Commencement Date"). The purchase price for the shares that we may sell to Lincoln Park under the Purchase Agreement will fluctuate based on the price of our common stock. Depending on market liquidity at the time, sales of such shares may cause the trading price of our common stock to decrease.

We generally have the right to control the timing and amount of any future sales of our shares to Lincoln Park. Additional sales of our common stock, if any, to Lincoln Park will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the additional shares of our common stock that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell additional shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us could result in substantial dilution to the interests of other holders of our common stock. Additionally, the sale of a substantial number of shares of our common stock to Lincoln Park, or the anticipation of such sales, could 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 sales.

Further, we are not restricted from issuing additional securities in the future, including our common stock, securities that are convertible into or exchangeable for, or that represent the right to receive, our common stock or substantially similar securities. To the extent that we raise additional funds through the sale of equity or convertible debt securities, the issuance of such securities will result in dilution to our stockholders.

We may require additional financing to sustain our operations, without which we may not be able to continue operations, and the terms of subsequent financings may adversely impact our stockholders.

We may direct Lincoln Park to purchase up to $30,000,000 worth of shares of our common stock under our agreement over a 24-month period in amounts up to 150,000 shares of our common stock, which may be increased depending on the market price of our common stock at the time of sale, and, in each

case, subject to a maximum limit of $1,000,000 per purchase, on any single business day (such share amounts being subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction as provided in the Purchase Agreement). Assuming a purchase price of $0.52 per share (the closing sale price of the common stock on September 5, 2024) and the purchase by Lincoln Park of 10,468,189 purchase shares, gross proceeds to us would only be $5.4 million.

The extent we rely on Lincoln Park as a source of funding will depend on a number of factors including the prevailing market price of our common stock and the extent to which we are able to secure financing from other sources. If obtaining sufficient financing from Lincoln Park were to prove unavailable or prohibitively dilutive, we may need to secure another source of funding in order to satisfy our financing needs. Even if we sell all $30,000,000 under the Purchase Agreement to Lincoln Park, we may still need additional capital to finance our future working capital needs, and we may have to raise funds through the issuance of equity or debt securities. Depending on the type and the terms of any financing we pursue, stockholders' rights and the value of their investment in our common stock could be reduced. A financing could involve one or more types of securities including common stock, convertible debt or warrants to acquire common stock. These securities could be issued at or below the then prevailing market price for our common stock. We currently have no authorized preferred stock. In addition, if we issue secured debt securities, the holders of the debt would have a claim to our assets that would be prior to the rights of stockholders until the debt is paid. Interest on these debt securities would increase costs and negatively impact operating results. If the issuance of new securities results in diminished rights to holders of our common stock, the market price of our common stock could be negatively impacted.

Should the financing we require to sustain our financing needs be unavailable or prohibitively expensive when we require it, the consequences could be a material adverse effect on our business, operating results, financial condition and prospects.

Our management will have broad discretion over the use of the net proceeds from our sale of shares of common stock to Lincoln Park, you may not agree with how we use the proceeds and the proceeds may not be invested successfully.

Our management will have broad discretion as to the use of the net proceeds from our sale of shares of common stock to Lincoln Park, and we could use them for purposes other than those contemplated at the time of commencement of this offering. Accordingly, you will be relying on the judgment of our management with regard to the use of those net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used as you may deem to be appropriate. It is possible that, pending their use, we may invest those net proceeds in a manner that may not yield a favorable, or any, return for us. The manner in which our management uses such funds could have a material adverse effect on our business, financial condition, operating results and cash flows.

Our stock price has been and may continue to be volatile and may fluctuate significantly, which may adversely impact investor confidence and results and increase the likelihood of securities class action litigation.

Our common stock price has experienced volatility in the past and may remain volatile in the future. For example, during 2023, the sale price of our common stock ranged from a high of $1.31 per share to a low of $0.49 per share. Volatility in our stock price can be driven by many factors including, but not limited to, general market conditions, market conditions in the energy materials industry, announcements that we may make regarding our business plans or strategy, including announcements concerning our anticipated battery-graphite business, the increase in the sale and issuance of shares of our common stock to finance our operations, and the accuracy of expectations and predictions of financial analysts and the market as they pertain to our future business prospects. In addition, the price of our common stock may increase or decrease substantially for reasons unrelated to our operating performance or prospects. If our common stock continues to experience price volatility, any shares investors purchase may rapidly lose some or substantially all of their value.

Stockholders of a public company sometimes bring securities class action suits against the company following periods of instability in the market price of that company's securities. If we were involved in a class action suit, it could divert a significant amount of our management's attention and other resources from our business and operations, which could harm our results of operations and require us to incur significant

expenses to defend the suit. Any such class action suit, whether or not successful, could harm our reputation and restrict our ability to raise capital in the future. In addition, if a claim is successfully made against us, we may be required to pay damages, which could have a material adverse effect on our results of operations and financial condition.

Furthermore, our ability to raise funds through the issuance of equity or otherwise use our common stock as consideration is impacted by the price of our common stock. A low stock price may adversely impact our ability to fund our operating and growth plans, including Phase I of the Kellyton Graphite Plant, which would harm our business and prospects.

The Company has no history of paying dividends on its common stock, and we do not anticipate paying dividends in the foreseeable future.

The Company has not previously paid dividends on its common stock. We currently anticipate that we will retain all of our available cash, if any, for use as working capital and for other general corporate purposes. Any payment of future dividends will be at the discretion of our Board of Directors and will depend upon, among other things, our earnings, financial condition, capital requirements, level of indebtedness, statutory and contractual restrictions applicable to the payment of dividends and other considerations that our Board of Directors deems relevant. Investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize a return on their investment.

Terms of subsequent financings may adversely impact holders of our securities.

In order to finance our future production plans and working capital needs, we may have to raise funds through the issuance of equity or debt securities. Depending on the type and the terms of any financing we pursue, holders of our securities' rights and the value of their investment in our common stock could be reduced. A financing could involve one or more types of securities including common stock, convertible debt or warrants to acquire common stock. These securities could be issued at or below the then prevailing market price for our common stock. We currently have no authorized preferred stock. In addition, if we issue secured debt securities, the holders of the debt would have a claim to our assets that would be senior to the rights of holders of our other securities until the debt is paid. Interest on these debt securities would increase financing and interest costs and could negatively our impact our operating results. If the issuance of new securities results in diminished rights to holders of our common stock, the market price of our common stock could be negatively impacted.

Stockholders would be diluted if we use common stock to raise capital, and the perception that such sales may occur, could cause the price of our common stock to decrease.

We plan to seek additional capital to carry out our business plan. This financing could involve one or more types of securities including common stock, convertible debt or warrants to acquire common stock. These securities could be issued at or below the then prevailing market price for our common stock. Any issuance of additional shares of our common stock could be dilutive to existing holders of our securities and could adversely affect the market price of our common stock.

THE LINCOLN PARK TRANSACTION

General

On August 30, 2024, we entered into a purchase agreement with Lincoln Park, pursuant to which Lincoln Park has agreed to purchase from us up to an aggregate of $30,000,000 of our common stock (subject to certain limitations) from time to time over the term of the Purchase Agreement. Also on August 30, 2024, we entered into a registration rights agreement with Lincoln Park, which we refer to in this prospectus as the Registration Rights Agreement. Pursuant to our obligations under the Registration Rights Agreement, we have filed with the SEC the registration statement that includes this prospectus to register for resale under the Securities Act the shares of common stock that have been or may be issued to Lincoln Park under the Purchase Agreement. Terms used but not defined herein shall have the respective meaning ascribed to each such term in the Purchase Agreement.

This prospectus covers the resale by the selling stockholder of 11,668,189 shares of our common stock, comprised of: (i) 600,000 Initial Commitment Shares that we issued to Lincoln Park; (ii) 600,000 Additional Commitment Shares that we may issue to Lincoln Park from time to time in connection with each purchase of common stock by Lincoln Park, in each case, as consideration for Lincoln Park's commitment to purchase shares of common stock under the Purchase Agreement; and (iii) 10,468,189 shares we have reserved for issuance and sale and may issue and sell to Lincoln Park in the future under the Purchase Agreement, if and when we sell shares to Lincoln Park under the Purchase Agreement.

We do not have the right to commence any sales of our common stock to Lincoln Park under the Purchase Agreement until all of the conditions set forth in the Purchase Agreement have been satisfied, including that the SEC has declared effective the registration statement that includes this prospectus registering the shares that will be issued and sold to Lincoln Park, which we refer to in this prospectus as the Commencement. Thereafter, we may, from time to time and at our sole discretion for a period of 24-months, on any business day that we select, direct Lincoln Park to purchase up to 150,000 shares of common stock, which amounts may be increased depending on the market price of our common stock at the time of sale, which we refer to in this prospectus as "regular purchases." In addition, at our discretion, Lincoln Park has committed to purchase other "accelerated amounts" and/or "additional accelerated amounts" under certain circumstances.

We will control the timing and amount of any sales of our common stock to Lincoln Park. The purchase price of the shares that may be sold to Lincoln Park in regular purchases under the Purchase Agreement will be based on an agreed upon fixed discount to the market price of our common stock immediately preceding the time of sale as computed under the Purchase Agreement. The purchase price per share will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, or other similar transaction occurring during the business days used to compute such price.

We may at any time in our sole discretion terminate the Purchase Agreement without fee, penalty or cost upon one business day notice. There are no restrictions on future financings, rights of first refusal, participation rights, penalties or liquidated damages in the Purchase Agreement or Registration Rights Agreement, other than a prohibition on us effecting or entering into an agreement to effect an "equity line of credit" or other continuous offering or similar offering in which we or our subsidiaries may offer, issue or sell common stock or any securities exercisable, exchangeable or convertible into common stock at a future determined price, subject to certain exemptions, for a period continuing until the earlier of: (A) the 90-day anniversary of the effective date of the termination of the Purchase Agreement, or (B) the later of (i) the 24-month anniversary of the date of the Purchase Agreement, or (ii) the 24-month anniversary of the Commencement Date. Lincoln Park may not assign or transfer its rights and obligations under the Purchase Agreement.

As of September 5, 2024, there were 58,970,133 shares of our common stock outstanding, of which 57,946,110 shares were held by non-affiliates, including the 600,000 Initial Commitment Shares that we have issued to Lincoln Park under the Purchase Agreement. Although the Purchase Agreement provides that we may sell up to an aggregate of $30,000,000 of our common stock to Lincoln Park, only 11,668,189 shares of our common stock are being offered under this prospectus, which represents the 600,000 Initial Commitment Shares that we issued to Lincoln Park under the Purchase Agreement, up to 600,000 Additional

Commitment Shares that we may issue to Lincoln Park from time to time under the Purchase Agreement, and the 10,468,189 shares which may be issued and sold to Lincoln Park in the future under the Purchase Agreement, if and when we sell shares to Lincoln Park under the Purchase Agreement. Depending on the market prices of our common stock at the time we elect to issue and sell shares to Lincoln Park under the Purchase Agreement, we may need to register for resale under the Securities Act additional shares of our common stock in order to receive aggregate gross proceeds equal to the $30,000,000 total commitment available to us under the Purchase Agreement. If all of the 11,668,189 shares offered by Lincoln Park under this prospectus were issued and outstanding as of the date hereof, such shares would represent approximately 16.7% of the total number of shares of our common stock outstanding and approximately 16.9% of the total number of outstanding shares held by non-affiliates, in each case as of the date hereof. If we elect to issue and sell more than the 11,668,189 shares offered under this prospectus to Lincoln Park, which we have the right, but not the obligation, to do, we must first (i) register for resale under the Securities Act any such additional shares, which could cause additional substantial dilution to our stockholders, and (ii) obtain stockholder approval to issue shares of common stock in excess of the Exchange Cap under the Purchase Agreement in accordance with NYSE American rules. The number of shares ultimately offered for resale by Lincoln Park is dependent upon the number of shares we sell to Lincoln Park under the Purchase Agreement.

Under applicable rules of NYSE American, in no event may the Company issue or sell to Lincoln Park under the Purchase Agreement any shares of its common stock to the extent the issuance of such shares of Common Stock, when aggregated with all other shares of common stock issued pursuant to the Purchase Agreement (including the Commitment Shares), would cause the aggregate number of shares of common stock issued pursuant to the Purchase Agreement to exceed the Exchange Cap, or 11,668,189 shares of common stock, unless and until the Company obtains stockholder approval to issue shares of common stock in excess of the Exchange Cap or otherwise, and in accordance with applicable NYSE American listing rules. The Purchase Agreement specifically provides that the Company may not issue or sell any shares of its common stock under the Purchase Agreement if such issuance or sale would breach any applicable NYSE American rules.

The Purchase Agreement also prohibits us from directing Lincoln Park to purchase any shares of common stock if those shares, when aggregated with all other shares of our common stock then beneficially owned by Lincoln Park and its affiliates, would result in Lincoln Park and its affiliates having beneficial ownership, at any single point in time, of more than 9.99% of the then total outstanding shares of our common stock, as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and Rule 13d-3 thereunder, which limitation we refer to as the Beneficial Ownership Cap.

Issuances of our common stock in this offering 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 as a result of any such issuance. Although the number of shares of common stock that our existing stockholders own will not decrease, the shares owned by our existing stockholders will represent a smaller percentage of our total outstanding shares after any such issuance to Lincoln Park.

Purchase of Shares Under the Purchase Agreement

Under the Purchase Agreement, upon Commencement, on any business day that we select (the "Purchase Date") (and provided (A) the closing sale price of our common stock on the Purchase Date is not less than $0.10 (as adjusted pursuant to the Purchase Agreement) and (B) all shares of common stock subject to all prior Regular Purchases and all Additional Commitment Shares required to be issued to Lincoln Park have been properly delivered to Lincoln Park in accordance with the Purchase Agreement), we may direct Lincoln Park to purchase up to 150,000 shares of our common stock in a regular purchase on such business day, which is referred to as a "Regular Purchase" in this prospectus, provided, however, that (i) the Regular Purchase may be increased to up to 200,000 shares, provided that the closing sale price of our common stock is not below $0.50 on the Purchase Date, (ii) the Regular Purchase may be increased to up to 250,000 shares, provided that the closing sale price of our common stock is not below $0.75 on the Purchase Date, and (iii) the Regular Purchase may be increased to up to 300,000 shares, provided that the closing sale price of the common stock is not below $1.00 on the Purchase Date (such share amount limitation, the

"Regular Purchase Share Limit"). In each case, Lincoln Park's maximum commitment in any single Regular Purchase may not exceed $1,000,000. The Regular Purchase Share Limit is subject to proportionate adjustment in the event of a reorganization, recapitalization, non-cash dividend, stock split or other similar transaction; provided, that if after giving effect to such full proportionate adjustment, the adjusted Regular Purchase Share Limit would preclude us from requiring Lincoln Park to purchase common stock at an aggregate purchase price equal to or greater than $100,000 in any single Regular Purchase, then the Regular Purchase Share Limit will not be fully adjusted, but rather the Regular Purchase Share Limit for such Regular Purchase shall be adjusted as specified in the Purchase Agreement, such that, after giving effect to such adjustment, the Regular Purchase Share Limit will be equal to (or as close as can be derived from such adjustment without exceeding) $100,000.

The purchase price per share for each such Regular Purchase will be equal to 97% of the lower of:

•

the lowest sale price for our common stock on the purchase date of such shares; and

​

•

the arithmetic average of the three lowest closing sale prices for our common stock during the 10 consecutive business days ending on the business day immediately preceding the purchase date of such shares.

​

In addition to Regular Purchases described above, we may also direct Lincoln Park, on the Purchase Date on which we have properly submitted a Regular Purchase notice directing Lincoln Park to purchase the maximum number of shares of our common stock that we are then permitted to include in a single Regular Purchase notice (and provided all shares of common stock subject to all prior Regular Purchases, Accelerated Purchases and Additional Accelerated Purchases effected prior to such Purchase Date and all Additional Commitment Shares required to be issued to Lincoln Park have been properly delivered to Lincoln Park in accordance with the Purchase Agreement), to purchase an additional amount of our common stock, which we refer to as an "Accelerated Purchase," on the next business day following such Purchase Date for such corresponding Regular Purchase, which we refer to as the "Accelerated Purchase Date," not to exceed the lesser of:

•

three times the number of shares of common stock purchased pursuant to the corresponding Regular Purchase; and

​

•

30% of the total number of shares of our common stock traded on NYSE American during the period on the applicable Accelerated Purchase Date beginning at the Accelerated Purchase Commencement Time (as defined in the Purchase Agreement) for such Accelerated Purchase and ending at the Accelerated Purchase Termination Time (as defined in the Purchase Agreement) for such Accelerated Purchase, which we refer to as the "Accelerated Purchase Measurement Period."

​

The purchase price per share for each such Accelerated Purchase will be equal to 97% of the lower of:

•

the volume weighted average price of our common stock during the Accelerated Purchase Measurement Period on the applicable Accelerated Purchase Date; and

​

•

the closing sale price of our common stock on the applicable Accelerated Purchase Date.

​

We may also direct Lincoln Park, not later than 1:00 p.m., Eastern Time, on a business day on which an Accelerated Purchase has been completed (the "Additional Accelerated Purchase Date"), to purchase an additional amount of our common stock, which we refer to as an "Additional Accelerated Purchase," not to exceed the lesser of:

•

three times the number of shares of common stock purchased pursuant to the Regular Purchase corresponding to the Accelerated Purchase that was completed on such Accelerated Purchase date on which an Additional Accelerated Purchase notice was properly received; and

​

•

30% of the total number of shares of our common stock traded on NYSE American during the period on the applicable Additional Accelerated Purchase Date beginning at the Additional Accelerated Purchase Commencement Time (as defined in the Purchase Agreement) for such Additional Accelerated Purchase and ending at the Additional Accelerated Purchase Termination Time (as defined in the Purchase Agreement) for such Additional Accelerated Purchase, which we refer to as the "Additional Accelerated Purchase Measurement Period."

​

We may, in our sole discretion, submit multiple Additional Accelerated Purchase notices to Lincoln Park prior to 1:00 p.m., Eastern Time, on a single Additional Accelerated Purchase Date, provided that (A) all prior Accelerated Purchases and Additional Accelerated Purchases (including those that have occurred earlier on the same day) have been completed and (B) all of the shares to be purchased thereunder (and under the corresponding Regular Purchase) and all Additional Commitment Shares required to be issued to Lincoln Park have been properly delivered to Lincoln Park in accordance with the Purchase Agreement.

The purchase price per share for each such Additional Accelerated Purchase will be equal to 97% of the lower of:

•

the volume weighted average price of our common stock during the Additional Accelerated Purchase Measurement Period on the applicable Additional Accelerated Purchase Date; and

​

•

the closing sale price of our common stock on the applicable Additional Accelerated Purchase Date.

​

In the case of the Regular Purchases, Accelerated Purchases and Additional Accelerated Purchases, the purchase price per share will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction occurring during the business days used to compute the purchase price.

Other than as described above, there are no trading volume requirements or restrictions under the Purchase Agreement, and we will control the timing and amount of any sales of our common stock to Lincoln Park.

Suspension Events

Suspension events under the Purchase Agreement include the following:

•

the effectiveness of the registration statement of which this prospectus forms a part lapses for any reason (including, without limitation, the issuance of a stop order), or such registration statement (or the prospectus forming a part thereof) are unavailable for the resale by Lincoln Park of our common stock offered hereby, and such lapse or unavailability continues for a period of 10 consecutive business days or for more than an aggregate of 30 business days in any 365-day period;

​

•

suspension by our principal market of our common stock from trading for a period of one business day;

​

•

the de-listing of our common stock from NYSE American, our principal market, provided our common stock is not immediately thereafter trading on The Nasdaq Capital Market, The Nasdaq Global Market, The Nasdaq Global Select Market, the New York Stock Exchange, the NYSE Arca, or the OTCQX or OTCQB operated by the OTC Markets Group Inc. (or any nationally recognized successors thereto);

​

•

the failure of our transfer agent to issue to Lincoln Park shares of our common stock within two business days after the applicable date on which Lincoln Park is entitled to receive such shares;

​

•

any breach of the representations or warranties or covenants contained in the Purchase Agreement or Registration Rights Agreement that has or could have a material adverse effect on us and, in the case of a breach of a covenant that is reasonably curable, that is not cured within five business days;

​

•

any voluntary or involuntary participation or threatened participation in insolvency or bankruptcy proceedings by or against us;

​

•

if at any time we are not eligible to transfer our common stock electronically; or

​

•

if at any time the Exchange Cap is reached, to the extent applicable.

​

Lincoln Park does not have the right to terminate the Purchase Agreement upon any of the suspension events set forth above. During a suspension event, all of which are outside of Lincoln Park's control, we may not direct Lincoln Park to purchase any shares of our common stock under the Purchase Agreement.

Our Termination Rights

We have the unconditional right, at any time, for any reason and without any payment or liability to us, to give notice to Lincoln Park to terminate the Purchase Agreement. In the event of bankruptcy proceedings by or against us, the Purchase Agreement will automatically terminate without action of any party.

No Short-Selling or Hedging by Lincoln Park

Lincoln Park has agreed that neither it nor any of its affiliates shall engage in any direct or indirect short-selling or hedging of our common stock during any time prior to the termination of the Purchase Agreement.

Prohibitions on Variable Rate Transactions

There are no restrictions on future financings, rights of first refusal, participation rights, penalties or liquidated damages in the Purchase Agreement or Registration Rights Agreement other than a prohibition on us effecting or entering into an agreement to effect an "equity line of credit" or other continuous offering or similar offering in which we or our subsidiaries may offer, issue or sell common stock or any securities exercisable, exchangeable or convertible into common stock at a future determined price, subject to certain exemptions, for a period continuing until the earlier of: (A) the 90-day anniversary of the effective date of the termination of the Purchase Agreement, or (B) the later of (i) the 24-month anniversary of the date of the Purchase Agreement, or (ii) the 24-month anniversary of the Commencement Date.

Effect of Performance of the Purchase Agreement on Our Stockholders

All 11,668,189 shares registered in this offering that have been and may be issued as Commitment Shares and may be issued or sold by us to Lincoln Park under the Purchase Agreement are expected to be freely tradable. It is anticipated that shares registered in this offering, excluding the Commitment Shares, will be sold to Lincoln Park over a period of up to 24-months commencing on the Commencement Date. The resale by Lincoln Park of a significant amount of shares registered in this offering, at any given time during the pendency of this offering, could cause the market price of our common stock to decline and to be volatile. Resales of our common stock to Lincoln Park, if any, will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the shares of our common stock that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us under the Purchase Agreement may result in substantial dilution to the interests of other holders of our common stock. In addition, if we sell a substantial number of shares to Lincoln Park 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 Lincoln Park 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. However, we have the right to control the timing and amount of any additional sales of our shares to Lincoln Park and the Purchase Agreement may be terminated by us at any time at our discretion without any cost to us.

Pursuant to the terms of the Purchase Agreement, we have the right, but not the obligation, to direct Lincoln Park to purchase up to $30,000,000 of our common stock. Depending on the price per share at which we sell our common stock to Lincoln Park pursuant to the Purchase Agreement, we may need to sell to Lincoln Park under the Purchase Agreement more shares of our common stock than are offered under this prospectus in order to receive aggregate gross proceeds equal to the $30,000,000 total commitment available to us under the Purchase Agreement. If we choose to do so, in addition to obtaining stockholder approval to issue shares of common stock in excess of the Exchange Cap under the Purchase Agreement in accordance with NYSE American rules, we must first register for resale under the Securities Act such additional shares of our common stock, which could cause additional substantial dilution to our stockholders. The number of shares ultimately offered for resale by Lincoln Park under this prospectus is dependent upon the number of shares we direct Lincoln Park to purchase under the Purchase Agreement.

The Purchase Agreement prohibits us from issuing or selling to Lincoln Park under the Purchase Agreement (i) shares of our common stock in excess of the Exchange Cap, unless we obtain stockholder

approval to issue shares in excess of the Exchange Cap, and (ii) any shares of our common stock if those shares, when aggregated with all other shares of our common stock then beneficially owned by Lincoln Park and its affiliates, would exceed the Beneficial Ownership Cap. We would seek stockholder approval before issuing shares in excess of the Exchange Cap.

The following table sets forth the amount of gross proceeds we would receive from Lincoln Park from our sale of shares to Lincoln Park under the Purchase Agreement at varying purchase prices:

​

(1)

Although the Purchase Agreement provides that we may sell up to $30,000,000 of our common stock to Lincoln Park, we are only registering 11,668,189 shares under this prospectus, which are equal to the Exchange Cap and include 600,000 shares issued to Lincoln Park as the Initial Commitment Shares and up to 600,000 additional shares that may be issued to Lincoln Park as the Additional Commitment Shares, in each case, as consideration for Lincoln Park's commitment to purchase shares of common stock under the Purchase Agreement, which may or may not cover all the shares we ultimately sell to Lincoln Park under the Purchase Agreement, depending on the purchase price per share. We would seek stockholder approval before issuing more than 11,668,189 shares to Lincoln Park. The number of shares to be issued as set forth in this column (i) gives effect to the Exchange Cap and (ii) is without regard for the Beneficial Ownership Cap.

​

(2)

The denominator is based on 58,970,133 shares outstanding as of September 5, 2024 (which number includes the 600,000 Initial Commitment Shares), adjusted to include the number of shares set forth in the column titled "Number of Registered Shares to be Issued if Full Purchase," which we would have sold to Lincoln Park, assuming the purchase price in the adjacent column. The numerator is based on the number of shares issuable under the Purchase Agreement, set forth in the column titled "Number of Registered Shares to be Issued if Full Purchase," at the corresponding assumed purchase price set forth in the adjacent column. The table does not give effect to the prohibition contained in the Purchase Agreement that prevents us from selling and issuing to Lincoln Park shares such that, after giving effect to such sale and issuance, Lincoln Park and its affiliates would beneficially own more than 9.99% of the then outstanding shares of our common stock.

USE OF PROCEEDS

This prospectus relates to shares of our common stock that may be offered and sold from time to time by Lincoln Park. We will receive no proceeds from the sale of shares of common stock by Lincoln Park in this offering. We may receive up to $30 million aggregate gross proceeds (subject to certain limitations) under the Purchase Agreement from any sales we make to Lincoln Park pursuant to the Purchase Agreement after the date of this prospectus. We estimate that the net proceeds to us from the sale of our common stock to Lincoln Park pursuant to the Purchase Agreement would be up to $28.5 million over an approximately 24-month period, assuming that we sell the full amount of our common stock that we have the right, but not the obligation, to sell to Lincoln Park under the Purchase Agreement, and after other estimated fees and expenses. See "Plan of Distribution" elsewhere in this prospectus for more information.

We intend to use any net proceeds that we received under the Purchase Agreement for general corporate purposes, which may include advancing the development of Phase I of the Kellyton Graphite Plant and our graphite business, developing the Coosa Graphite Deposit, and making additions to our working capital. It is possible that no shares will be issued under the Purchase Agreement.

MARKET FOR COMMON STOCK AND DIVIDEND POLICY

Our common stock is traded on NYSE American under the symbol "WWR." The last reported sale price of our common stock on September 5, 2024 on NYSE American was $0.52 per share. As of March 15, 2024, there were 69 holders of record of our common stock.

We have never paid any cash or other dividends on our common stock, and we do not anticipate paying dividends for the foreseeable future. We expect to retain our earnings, if any, for the growth and development of our business. Any future determination to declare dividends will be made at the discretion of our Board and will depend on our financial condition, results of operations, capital requirements, general business conditions and other factors that our Board may consider relevant.

SELLING STOCKHOLDER

This prospectus relates to the possible resale by the selling stockholder, Lincoln Park, of shares of our common stock that have been or may be issued to Lincoln Park pursuant to the Purchase Agreement. We are filing the registration statement of which this prospectus forms a part pursuant to the provisions of the Registration Rights Agreement, which we entered into with Lincoln Park on August 30, 2024, concurrently with our execution of the Purchase Agreement, in which we agreed to provide certain registration rights with respect to sales by Lincoln Park of the shares of our common stock that have been or may be issued to Lincoln Park under the Purchase Agreement.

Lincoln Park, as the selling stockholder, may, from time to time, offer and sell pursuant to this prospectus any or all of the shares that we may issue to Lincoln Park from time to time at our discretion under the Purchase Agreement. The "selling stockholder" may sell some, all or none of its shares. We do not know how long the selling stockholder will hold the shares before selling them, and we currently have no agreements, arrangements or understandings with the selling stockholder regarding the sale of any of the shares.

The following table presents information regarding the selling stockholder and the shares that it may offer and sell from time to time under this prospectus. The table is prepared based on information supplied to us by the selling stockholder, and reflects its holdings as of September 5, 2024. Neither Lincoln Park nor any of its affiliates has held a position or office, or had any other material relationship, with us or any of our predecessors or affiliates. Beneficial ownership is determined in accordance with Section 13(d) of the Exchange Act and Rule 13d-3 thereunder. The percentage of shares beneficially owned prior to the offering is based on 58,970,133 shares of our common stock outstanding as of September 5, 2024.

​

Assumes the sale of all shares of common stock registered pursuant to this prospectus, although the selling stockholder is under no obligation known to us to sell any shares of common stock at this time.

Furthermore, under the terms of the Purchase Agreement, issuances and sales of shares of our common stock to Lincoln Park are subject to certain limitations on the amounts we may sell to Lincoln Park at any time, including the Exchange Cap and the Beneficial Ownership Cap. See the description under the heading "Lincoln Park Transaction" for more information about the Purchase Agreement.

​

The sale of the common stock offered by this prospectus could be effected in one or more of the following methods:

ordinary brokers' transactions;

any combination of the foregoing.

​

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.

Lincoln Park is an "underwriter" within the meaning of Section 2(a)(11) of the Securities Act.

Lincoln Park has informed us that it intends to use an unaffiliated broker-dealer to effectuate all sales, if any, of the common stock that it may purchase from us pursuant to the Purchase Agreement. Such sales will be made at prices and at terms then prevailing or at prices related to the then current market price. Each such unaffiliated broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act. Lincoln Park has informed us that each such broker-dealer will receive commissions from Lincoln Park that will not exceed customary brokerage commissions.

Brokers, dealers, underwriters or agents participating in the distribution of the shares 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 common stock sold by Lincoln Park through this prospectus. The compensation paid to any such particular broker-dealer by any such purchasers of common stock sold by Lincoln Park may be less than or in excess of customary commissions. Neither we nor Lincoln Park can presently estimate the amount of compensation that any agent will receive from any purchasers of common stock sold by Lincoln Park.

We know of no existing arrangements between Lincoln Park or any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares offered by this prospectus.

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 the names of any brokers, dealers, underwriters or agents participating in the distribution of such shares by the selling stockholder, any compensation paid by Lincoln Park to any such brokers, dealers, underwriters or agents, and any other required information.

We have agreed to indemnify Lincoln Park and certain other persons against certain liabilities in connection with the offering of shares of 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. Lincoln Park has agreed to indemnify us

against liabilities under the Securities Act that may arise from certain written information furnished to us by Lincoln Park specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities.

Lincoln Park has represented to us that at no time prior to the date of the Purchase Agreement has Lincoln Park or its agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of our common stock or any hedging transaction, which establishes a net short position with respect to our common stock. Lincoln Park agreed that during the term of the Purchase Agreement, it, its agents, representatives or affiliates will not enter into or effect, directly or indirectly, any of the foregoing transactions.

We have advised Lincoln Park 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.

This offering will terminate on the date that all shares offered by this prospectus have been sold by Lincoln Park.

Our common stock is traded on NYSE American under the symbol "WWR."

DESCRIPTION OF COMMON STOCK

The following description of our common stock and the material provisions of our restated certificate of incorporation, as amended, and amended and restated bylaws is only a summary. You should refer to the terms of our common stock contained in our restated certificate of incorporation, as amended, and our amended and restated bylaws for more complete information.

Our certificate of incorporation authorizes us to issue 200,000,000 shares of common stock, par value $0.001 per share. As of September 5, 2024, there were 58,970,294 shares of our common stock issued and 58,970,133 shares of our common stock outstanding, all of which are fully paid and non-assessable. As of September 5, 2024, there were 649,345 shares of common stock issuable upon the exercise of outstanding options, 4,117,189 shares of common stock issuable upon the vesting of outstanding restricted stock units and 100,003 additional shares of common stock reserved for future issuance under our 2013 Omnibus Incentive Plan, as amended. As of such date, there were also 114,429 additional shares of common stock reserved for future issuance under our Employment Inducement Incentive Award Plan.

Each share of our common stock is entitled to one vote for all purposes and cumulative voting is not permitted in the election of directors. Accordingly, the holders of more than fifty percent of all of the outstanding shares of our common stock can elect all of the directors. Matters to be voted upon by the holders of our common stock require the affirmative vote of a majority of the votes cast at a stockholders meeting at which a quorum is present.

There are no preemptive, subscription, conversion or redemption rights pertaining to our common stock. The absence of preemptive rights could result in a dilution of the interest of existing stockholders should additional shares of common stock be issued. Holders of our common stock are entitled to receive such dividends as may be declared by our Board out of assets legally available and to share ratably in our assets upon liquidation.

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

Our common stock is listed on NYSE American under the symbol "WWR."

Possible Anti-Takeover Effects of Delaware Law and our Restated Certificate of Incorporation and Amended and Restated Bylaws

Certain provisions of Delaware law, our restated certificate of incorporation and our amended and restated bylaws discussed below could discourage or make it more difficult to accomplish a proxy contest or other change in our management or the acquisition of control by a holder of a substantial amount of our common stock. It is possible that these provisions could make it more difficult to accomplish, or could deter, transactions that stockholders may otherwise consider to be in their best interests or in our best interests. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our Board and in the policies formulated by the Board and may discourage certain types of transactions that may involve an actual or threatened change of control of us. The provisions also are intended to discourage certain tactics that may be used in proxy fights. Such provisions also may have the effect of preventing changes in our management.

Delaware Statutory Business Combinations Provision

We are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. For purposes of Section 203, a "business combination" is defined broadly to include a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder, and, subject to certain exceptions, an "interested stockholder" is a person who, together with his or her affiliates and associates, owns (or within three years prior, did own) 15% or more of the corporation's voting stock.

Authorized but Unissued Stock

Our restated certificate of incorporation authorizes us to issue 200,000,000 shares of common stock, par value $0.001 per share. As of September 5, 2024, there were 58,970,294 shares of our common stock issued and 58,970,133 shares of our common stock outstanding, all of which are fully paid and non-assessable. Our Board has the authority, without further approval of the stockholders and subject to certain restrictions imposed by NYSE American, to issue authorized but unissued shares, which issuances would adversely affect the voting power and ownership interest of holders of our common stock. This authority may have the effect of deterring hostile takeovers, delaying or preventing a change in control, and discouraging bids for our common stock at a premium over the market price.

Advance Notice Provisions for Stockholder Proposals and Stockholder Nominations of Directors

Our amended and restated bylaws, for nominations to the Board of Directors or for other business to be properly brought by a stockholder before a meeting of stockholders (other than proposals to be included in the Company's proxy statement pursuant to Rule 14a-8 under the Exchange Act), requires, among other requirements: a stockholder to have given timely and proper notice thereof in writing to the Secretary of the Company; a stockholder to constitute an Eligible Holder and meet certain ownership requirements; a Stockholder Notice to include certain information about the proposing stockholders, Stockholder Associated Persons and proposed nominees; each proposed nominee to complete a written questionnaire with respect to the background and qualifications of such proposed nominee, in the form required by the Company; each proposed nominee to enter into a written representation and agreement in the form required by the Company; that a stockholder cannot include in a Stockholder Notice more proposed nominees for election as directors than the number of directors to be elected to the Board at the stockholders' meeting to which that Stockholder Notice relates; that the Company may require any stockholder providing a Stockholder Notice with respect to a proposed nominee to furnish such other information (i) as may be reasonably required by the Company to determine the eligibility or suitability of such proposed nominee to serve as a director, or (ii) that could be material to a reasonable stockholder's understanding of the independence, or lack thereof, of such proposed nominee; and that a stockholder, at all times before and after the submission of a Stockholder Notice, comply with all applicable requirements of state law and of the Exchange Act and the rules and regulations thereunder (including, but not limited to, the requirements contained in Rule 14a-19 of the Exchange Act), as well as any interpretative guidance and/or requests from the Staff of the SEC, in connection with submitting a Stockholder Notice and taking any actions contemplated thereby. Defined terms used in but not defined in this provision shall have the meanings ascribed to such terms in the amended and restated bylaws. Detailed requirements as to the form of the notice and information required in the notice are specified in the amended and restated bylaws. If it is determined that business was not properly brought before a meeting in accordance with our bylaw provisions, such business will not be conducted at the meeting.

Amendment of Bylaws

Our Board is expressly authorized to alter or repeal our amended and restated bylaws.

Special Meetings of Stockholders

Special meetings of the stockholders may be called only by our Chairman, President or pursuant to a resolution adopted by a majority of the total number of directors. Stockholders may not propose business to be brought before a special meeting of the stockholders.
