Exhibit 4.5

DESCRIPTION OF THE REGISTRANT’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

As of December 31, 2021, Welsbach Technology Metals Acquisition Corp. (“we,” “our,” “us” or the “Company”) had the following three classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): (i) its units, consisting of one share of common stock (as defined below) and one right (as defined below), with each right entitling the holder thereof to receive one-tenth of one share of common stock (the “units”), (ii) its common stock, $0.0001 par value per share (“common stock”), and (iii) its public rights, with each right exchangeable for one-tenth of one share of common stock (the “rights”).

Pursuant to our amended and restated certificate of incorporation, our authorized capital stock consists of 100,000,000 shares of common stock and 1,000,000 shares of undesignated preferred stock, $0.0001 par value. The following description summarizes the material terms of our capital stock and does not purport to be complete. It is subject to, and qualified in its entirety by reference to, our amended and restated certificate of incorporation, our amended and restated bylaws and our warrant agreement, each of which is incorporated by reference as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2021 (the “Report”) of which this Exhibit 4.5 is a part.

Defined terms used herein but not otherwise defined shall have the meaning ascribed to such terms in the Report.

Units

Each unit consists of one share of common stock and one right. Each right entitles the holder thereof to receive one-tenth (1/10) of a share of common stock upon consummation of our initial business combination. In addition, we will not issue fractional shares in connection with an exchange of rights. Fractional shares will either be rounded down to the nearest whole share or otherwise addressed in accordance with the applicable provisions of Delaware Law. As a result, you must hold rights in multiples of 10 in order to receive shares for all of your rights upon closing of a business combination.

Common Stock

Our holders of record of our common stock are entitled to one vote for each share held on all matters to be voted on by stockholders. In connection with any vote held to approve our initial business combination, our insiders, officers and directors, have agreed to vote their respective shares of common stock owned by them immediately prior to our initial public offering, including both the founder shares and the private shares, and any shares acquired in our initial public offering or following our initial public offering in the open market, in favor of the proposed business combination.

We will consummate our initial business combination only if public stockholders do not exercise conversion rights in an amount that would cause our net tangible assets to be less than $5,000,001 and a majority of the outstanding shares of common stock voted are voted in favor of the business combination.

Pursuant to our certificate of incorporation, if we do not consummate our initial business combination within 9 months from the closing of our initial public offering, or September 30, 2022, we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors, dissolve and liquidate, subject (in the case of (ii) and (iii) above) to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Our insiders have agreed to waive their rights to share in any distribution with respect to their founder shares and private shares. However, if we anticipate that we may not be able to consummate our initial business combination within 9 months, our insiders or their affiliates may, but are not obligated to, extend the period of time to consummate a business combination by an additional three months each time for a total of up to 15 months to complete a business combination, or March 30, 2023, provided that, pursuant to the terms of our amended and restated certificate of incorporation and the trust agreement entered into between us and Continental, our insiders or their affiliates or designees, upon five days’ advance notice prior to the applicable deadline, deposit into the trust account $772,686.60, or ($0.10 per share), on or prior to the date of the applicable deadline. In the event that they elected to extend the time to complete a business combination and deposited the applicable amount of money into trust, the insiders would receive a non-interest bearing, unsecured promissory note equal to the amount of any such deposit that will not be repaid in the event that we are unable to close a business combination unless there are funds available outside the trust account to do so. Such notes would either be paid upon consummation of our initial business combination solely from funds available outside of the trust account or, at the relevant insider’s discretion, converted upon consummation of our business combination into additional private units at a price of $10.00 per unit. Our stockholders have approved the issuance of the private units upon conversion of such notes, to the extent the holder wishes to so convert such notes at the time of the consummation of our initial business combination. In the event that we receive notice from our insiders five days prior to the applicable deadline of their intent to effect an extension, we intend to issue a press release announcing such intention at least three days prior to the applicable deadline. In addition, we intend to issue a press release the day after the applicable deadline announcing whether or not the funds had been timely deposited. Our insiders and their affiliates or designees are not obligated to fund the trust account to extend the time for us to complete our initial business combination. To the extent that some, but not all, of our insiders, decide to extend the period of time to consummate our initial business combination, such insiders (or their affiliates or designees) may deposit the entire amount required.

Our stockholders have no conversion, preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable to the shares of common stock, except that public stockholders have the right to sell their shares to us in any tender offer or have their shares of common stock converted to cash equal to their pro rata share of the trust account if they vote on the proposed business combination and the business combination is completed. If we hold a stockholder vote to amend any provisions of our certificate of incorporation relating to stockholder’s rights or pre-business combination activity (including the substance or timing within which we have to complete a business combination), we will provide our public stockholders with the opportunity to redeem their shares of common stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our franchise and income taxes, divided by the number of then outstanding public shares, in connection with any such vote. In either of such events, converting stockholders would be paid their pro rata portion of the trust account promptly following consummation of the business combination or the approval of the amendment to the certificate of incorporation. If the business combination is not consummated or the amendment is not approved, stockholders will not be paid such amounts.

Rights

Except in cases where we are not the surviving company in a business combination, each holder of a right will automatically receive one-tenth (1/10) of a share of common stock upon consummation of our initial business combination, even if the holder of a public right converted all shares of common stock held by him, her or it in connection with the initial business combination or an amendment to our certificate of incorporation with respect to our pre-business combination activities. In the event we will not be the surviving company upon completion of our initial business combination, each holder of a right will be required to affirmatively convert his, her or its rights in order to receive the one-tenth (1/10) of a share underlying each right upon consummation of the business combination. No additional consideration will be required to be paid by a holder of rights in order to receive his, her or its additional shares of common stock upon consummation of an initial business combination. The shares issuable upon exchange of the rights will be freely tradable (except to the extent held by affiliates of ours). If we enter into a definitive agreement for a business combination in which we will not be the surviving entity, the definitive agreement will provide for the holders of rights to receive the same per share consideration the holders of the common stock will receive in the transaction on an as-converted into common stock basis.

We will not issue fractional shares in connection with an exchange of rights. Fractional shares will either be rounded down to the nearest whole share or otherwise addressed in accordance with the applicable provisions of the Delaware General Corporation Law. As a result, you must hold rights in multiples of 10 in order to receive shares for all of your rights upon closing of a business combination. If we are unable to complete an initial business combination within the required time period and we liquidate the funds held in the trust account, holders of rights will not receive any of such funds with respect to their rights, nor will they receive any distribution from our assets held outside of the trust account with respect to such rights, and the rights will expire worthless. Further, there are no contractual penalties for failure to deliver securities to the holders of the rights upon consummation of an initial business combination. Additionally, in no event will we be required to net cash settle the rights. Accordingly, the rights may expire worthless.
