Description of the Company's securities

Exhibit 4.5

DRUGS MADE IN AMERICA ACQUISITION CORP.

DESCRIPTION OF SECURITIES

The following summary of the material terms of the securities of Drugs Made In America Acquisition Corp. (“we,” “us,” “our” or “the Company”) is not intended to be a complete summary of the rights and preferences of such securities and is subject to and qualified by reference to our amended and restated memorandum and articles of association incorporated by reference as an exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (the “Report”) and applicable Cayman Islands law.

Pursuant to our amended and restated memorandum and articles of association, our authorized share capital consists of 220,000,000 ordinary shares, $0.0001 par value each, and 1,000,000 preference shares, $0.0001 par value each. The following description summarizes the material terms of our share capital.

UNITS

Each unit consists of one ordinary share and one right to receive one-eighth (1/8) of an ordinary share upon the consummation of an initial business combination, as described in more detail below. We will not issue fractional shares. Fractional shares will either be rounded down to the nearest whole share or otherwise addressed in accordance with the applicable provisions of Cayman Islands law.

The ordinary shares and rights comprising the units began separate trading on February 25, 2025. Holders have subsequently had the option to continue to hold units or separate their units into the component securities. Holders will need to have their brokers contact our transfer agent in order to separate the units into ordinary shares and rights. No fractional rights will be issued upon separation of the units and only whole rights will trade.

Additionally, the units will automatically separate into their component parts and will not be traded after completion of our initial business combination.

ORDINARY SHARES

As of the date of the Report, 33,517,143 ordinary shares are issued and outstanding.

Holders of record of ordinary shares are entitled to one vote for each share held on all matters to be voted on by shareholders and vote together as a single class, except as required by law.

Unless specified in our amended and restated memorandum and articles of association, or as required by applicable law or stock exchange rules, the affirmative vote of holders of a majority of the outstanding ordinary shares that are voted is required to approve any such matter voted on by our shareholders. Our board of directors will be divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected in each year. There is no cumulative voting with respect to the appointment of directors. Our shareholders are entitled to receive ratable dividends when, as and if declared by the board of directors out of funds legally available therefor.

Because our amended and restated memorandum and articles of association will authorize the issuance of up to 220,000,000 ordinary shares, if we were to enter into a business combination, we may (depending on the terms of such a business combination) be required to increase the number of ordinary shares which we are authorized to issue at the same time as our shareholders vote on the business combination to the extent we seek shareholder approval in connection with our initial business combination.

In accordance with Nasdaq corporate governance requirements, we are not required to hold an annual general meeting until one year after our first fiscal year end following our listing on Nasdaq.

Pursuant to our amended and restated memorandum and articles of association, if we have not completed our initial business combination within the completion window, we will (1) cease all operations except for the purpose of winding up, (2) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest (net of funds withdrawn to pay our taxes, if any, and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), and (3) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our board of directors, liquidate and dissolve, subject in each case to our obligations under Cayman laws to provide for claims of creditors and the requirements of other applicable law. Our initial shareholders have entered into a letter agreement with us, pursuant to which they have agreed to waive their rights to liquidating distributions from the trust account with respect to their founder shares and private shares if we fail to complete our initial business combination within the completion window. However, if our initial shareholders or any of our directors, officers or affiliates acquire public shares, they will be entitled to liquidating distributions from the trust account with respect to such public shares if we fail to complete our initial business combination within the prescribed time period.

In the event of a liquidation, dissolution or winding up of the company after a business combination, our shareholders at such time will be entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of shares, if any, having preference over the ordinary shares. Our shareholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the ordinary shares, except that we will provide our shareholders with the opportunity to redeem their public shares for cash equal to their pro rata share of the aggregate amount then on deposit in the trust account, including interest (net of funds withdrawn to pay our taxes, if any, and up to $100,000 of interest to pay dissolution expenses), upon the completion of our initial business combination, subject to the limitations described herein.

FOUNDER SHARES

The founder shares are identical to the ordinary shares included in the units being sold in our initial public offering, and holders of founder shares have the same shareholder rights as public shareholders, except that: (1) the founder shares are subject to certain transfer restrictions contained in a letter agreement that our initial shareholders, directors and officers have entered into with us, as described in more detail below; (2) pursuant to such letter agreement, our initial shareholders, directors and officers have agreed to waive: (i) their redemption rights with respect to any shares held by them, as applicable, in connection with the completion of our initial business combination; (ii) their redemption rights with respect to any shares held by them in connection with a shareholder vote to amend our amended and restated memorandum and articles of association (A) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we do not complete our initial business combination within the completion window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity; and (iii) their rights to liquidating distributions from the trust account with respect to any founder shares and private shares they hold if we fail to complete our initial business combination within the completion window (although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete our initial business combination within the completion window); and (3) the founder shares are entitled to registration rights. If we submit our initial business combination to our public shareholders for a vote, our initial shareholders, directors and officers have agreed (and their permitted transferees will agree), pursuant to the terms of a letter agreement entered into with us, to vote any shares held by them in favor of our initial business combination.

Pursuant to a letter agreement that our initial shareholders, directors and officers have entered into with us, with certain limited exceptions, the founder shares and the private units, including the underlying private shares and private rights, are not transferable, assignable or salable (except to our directors and officers and other persons or entities affiliated with our initial shareholders, each of whom will be subject to the same transfer restrictions) until the earlier of: (i) with respect to 50% of the founder shares and private units, the earlier of six months after the date of the consummation of our initial business combination and the date on which the closing price of our ordinary shares equals or exceeds $12.50 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing after our initial business combination and (ii) with respect to the remaining 50% of the founder shares and private units, six months after the date of the consummation of our initial business combination, or earlier, in either case, if, subsequent to our initial business combination, we consummate a liquidation, merger, share exchange or other similar transaction which results in all of our shareholders having the right to exchange their ordinary shares for cash, securities or other property.

Register of Members

Under Cayman Islands law, we must keep a register of members and there will be entered therein:

Under Cayman Islands law, the register of members of our company is prima facie evidence of the matters set out therein (i.e., the register of members will raise a presumption of fact on the matters referred to above unless rebutted) and a member registered in the register of members will be deemed as a matter of Cayman Islands law to have legal title to the shares as set against its name in the register of members. The shareholders recorded in the register of members will be deemed to have legal title to the shares set against their name. However, there are certain limited circumstances where an application may be made to a Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. If an application for an order for rectification of the register of members were made in respect of our ordinary shares, then the validity of such shares may be subject to re-examination by a Cayman Islands court.

PREFERENCE SHARES

Our amended and restated memorandum and articles of association authorize 1,000,000 preference shares and provide that preference shares may be issued from time to time in one or more series. Our board of directors are authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. Our board of directors is able to, without shareholder approval, issue preference shares with voting and other rights that could adversely affect the voting power and other rights of the holders of the ordinary shares and could have anti-takeover effects. The ability of our board of directors to issue preference shares without shareholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no preference shares issued and outstanding at the date hereof. As of the date of the Report, no preference shares are issued and outstanding.

RIGHTS

Except in cases where we are not the surviving company in a business combination, each holder of a right will automatically receive one-eighth (1/8) of one ordinary share upon consummation of our initial business combination, even if the holder of a public right redeemed all ordinary shares held by it in connection with the initial business combination or an amendment to our amended and restated memorandum and articles of association 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 its rights in order to receive the one-eighth (1/8) of one ordinary 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 its additional ordinary shares upon consummation of an initial business combination. 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 ordinary shares will receive in the transaction on an as-converted into ordinary share 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 Cayman Islands law. 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.

We have agreed that, subject to applicable law, any action, proceeding or claim against us arising out of or relating in any way to the rights agreement will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and we irrevocably submit to such jurisdiction, which jurisdiction will be the exclusive forum for any such action, proceeding or claim. Notwithstanding the foregoing, this provision does not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum. We note that there is uncertainty as to whether a court would enforce such provision, and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. The Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

DIVIDENDS

We have not paid any cash dividends on our ordinary shares to date and do not intend to pay cash dividends prior to the completion of our initial business combination. A Cayman Islands company may pay a dividend on its shares out of either profit or the share premium account, provided that in no circumstances may a dividend be paid if following such payment the company would be unable to pay its debts as they fall due in the ordinary course of business. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition subsequent to completion of our initial business combination. The payment of any cash dividends subsequent to our initial business combination will be within the discretion of our board of directors at such time. In addition, our board of directors is not currently contemplating and does not anticipate declaring any share dividends in the foreseeable future. Further, if we incur any indebtedness in connection with our initial business combination, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.

OUR TRANSFER AGENT AND RIGHTS AGENT

The transfer agent for our ordinary shares and rights agent for our rights is VStock Transfer, LLC. We have agreed to indemnify VStock Transfer, LLC in its roles as transfer agent and rights agent, its agents and each of its shareholders, directors, officers and employees against all liabilities, including judgments, costs and reasonable counsel fees that may arise out of acts performed or omitted for its activities in that capacity, except for any liability due to any gross negligence, willful misconduct or bad faith of the indemnified person or entity.

CERTAIN DIFFERENCES IN CORPORATE LAW

Cayman Islands companies are governed by the Companies Act. The Companies Act is modeled on English Law but does not follow recent English Law statutory enactments, and differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of the material differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the United States and their shareholders.

Mergers and Similar Arrangements.    In certain circumstances, the Companies Act allows for mergers or consolidations between two Cayman Islands companies, or between a Cayman Islands exempted company and a company incorporated in another jurisdiction (provided that is facilitated by the laws of that other jurisdiction).

Where the merger or consolidation is between two Cayman Islands companies, the directors of each company must approve a written plan of merger or consolidation containing certain prescribed information. That plan or merger or consolidation must then be authorized by either (a) a special resolution (a majority of two-thirds of the voting shares voted at a general meeting) of the shareholders of each company; or (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. No shareholder resolution is required for a merger between a parent company (i.e., a company that owns at least 90% of the issued shares of each class in a subsidiary company) and its subsidiary company. The consent of each holder of a fixed or floating security interest of a constituent company must be obtained, unless the court waives such requirement. If the Cayman Islands Registrar of Companies is satisfied that the requirements of the Companies Act (which includes certain other formalities) have been complied with, the Registrar of Companies will register the plan of merger or consolidation.

Where the merger or consolidation involves a foreign company, the procedure is similar, save that with respect to the foreign company, the directors of the Cayman Islands exempted company are required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (i) that the merger or consolidation is permitted or not prohibited by the constitutional documents of the foreign company and by the laws of the jurisdiction in which the foreign company is incorporated, and that those laws and any requirements of those constitutional documents have been or will be complied with; (ii) that no petition or other similar proceeding has been filed and remains outstanding or order made or resolution adopted to wind up or liquidate the foreign company in any jurisdictions; (iii) that no receiver, trustee, administrator or other similar person has been appointed in any jurisdiction and is acting in respect of the foreign company, its affairs or its property or any part thereof; and (iv) that no scheme, order, compromise or other similar arrangement has been entered into or made in any jurisdiction whereby the rights of creditors of the foreign company are and continue to be suspended or restricted.

Where the surviving company is the Cayman Islands exempted company, the directors of the Cayman Islands exempted company are further required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (i) that the foreign company is able to pay its debts as they fall due and that the merger or consolidated is bona fide and not intended to defraud unsecured creditors of the foreign company; (ii) that in respect of the transfer of any security interest granted by the foreign company to the surviving or consolidated company (a) consent or approval to the transfer has been obtained, released or waived; (b) the transfer is permitted by and has been approved in accordance with the constitutional documents of the foreign company; and (c) the laws of the jurisdiction of the foreign company with respect to the transfer have been or will be complied with; (iii) that the foreign company will, upon the merger or consolidation becoming effective, cease to be incorporated, registered or exist under the laws of the relevant foreign jurisdiction; and (iv) that there is no other reason why it would be against the public interest to permit the merger or consolidation.

Where the above procedures are adopted, the Companies Act provides for a right of dissenting shareholders to be paid a payment of the fair value of his shares upon their dissenting to the merger or consolidation if they follow a prescribed procedure. In essence, that procedure is as follows: (a) the shareholder must give his written objection to the merger or consolidation to the constituent company before the vote on the merger or consolidation, including a statement that the shareholder proposes to demand payment for his shares if the merger or consolidation is authorized by the vote; (b) within 20 days following the date on which the merger or consolidation is approved by the shareholders, the constituent company must give written notice to each shareholder who made a written objection; (c) a shareholder must within 20 days following receipt of such notice from the constituent company, give the constituent company a written notice of his intention to dissent including, among other details, a demand for payment of the fair value of his shares; (d) within seven days following the date of the expiration of the period set out in paragraph (b) above or seven days following the date on which the plan of merger or consolidation is filed, whichever is later, the constituent company, the surviving company or the consolidated company must make a written offer to each dissenting shareholder to purchase his shares at a price that the company determines is the fair value and if the company and the shareholder agree the price within 30 days following the date on which the offer was made, the company must pay the shareholder such amount; and (e) if the company and the shareholder fail to agree a price within such 30 day period, within 20 days following the date on which such 30 day period expires, the company (and any dissenting shareholder) must file a petition with the Cayman Islands Grand Court to determine the fair value and such petition must be accompanied by a list of the names and addresses of the dissenting shareholders with whom agreements as to the fair value of their shares have not been reached by the company. At the hearing of that petition, the court has the power to determine the fair value of the shares together with a fair rate of interest, if any, to be paid by the company upon the amount determined to be the fair value. Any dissenting shareholder whose name appears on the list filed by the company may participate fully in all proceedings until the determination of fair value is reached. These rights of a dissenting shareholder are not available in certain circumstances, for example, to dissenters holding shares of any class in respect of which an open market exists on a recognized stock exchange or recognized interdealer quotation system at the relevant date or where the consideration for such shares to be contributed are shares of any company listed on a national securities exchange or shares of the surviving or consolidated company.

Moreover, Cayman Islands law has separate statutory provisions that facilitate the reconstruction or amalgamation of companies in certain circumstances, schemes of arrangement will generally be more suited for complex mergers or other transactions involving widely held companies, commonly referred to in the Cayman Islands as a “scheme of arrangement” which may be tantamount to a merger. In the event that a merger was sought pursuant to a scheme of arrangement (the procedures for which are more rigorous and take longer to complete than the procedures typically required to consummate a merger in the United States), the arrangement in question must be approved by a majority in number of each class of shareholders and creditors with whom the arrangement is to be made and who must in addition represent three-fourths in value of each such class of shareholders or creditors, as the case may be, that are present and voting either in person or by proxy at an annual general meeting, or extraordinary general meeting summoned for that purpose. The convening of the meetings and subsequently the terms of the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder would have the right to express to the court the view that the transaction should not be approved, the court can be expected to approve the arrangement if it satisfies itself that:

If a scheme of arrangement or takeover offer (as described below) is approved, any dissenting shareholder would have no rights comparable to appraisal rights (providing rights to receive payment in cash for the judicially determined value of the shares), which would otherwise ordinarily be available to dissenting shareholders of United States corporations.

Squeeze-out Provisions. When a takeover offer is made and accepted by holders of 90% of the shares to whom the offer relates within four months, the offeror may, within a two-month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands, but this is unlikely to succeed unless there is evidence of fraud, bad faith, collusion or inequitable treatment of the shareholders.

Further, transactions similar to a merger, reconstruction and/or an amalgamation may in some circumstances be achieved through means other than these statutory provisions, such as a share capital exchange, asset acquisition or control, or through contractual arrangements of an operating business.

Shareholders’ Suits.    Derivative actions have been brought in the Cayman Islands courts, and the Cayman Islands courts have confirmed the availability for such actions. In most cases, we will be the proper plaintiff in any claim based on a breach of duty owed to us, and a claim against (for example) our officers or directors usually may not be brought by a shareholder. However, based both on Cayman Islands authorities and on English authorities, which would in all likelihood be of persuasive authority and be applied by a court in the Cayman Islands, exceptions to the foregoing principle apply in circumstances in which:

A shareholder may have a direct right of action against us where the individual rights of that shareholder have been infringed or are about to be infringed.

Enforcement of Civil Liabilities. The Cayman Islands has a different body of securities laws as compared to the United States and provides less protection to investors. Additionally, Cayman Islands companies may not have standing to sue before the Federal courts of the United States.

The courts of the Cayman Islands are unlikely (i) to recognize or enforce against us judgments of courts of the United States predicated upon the civil liability provisions of the federal securities laws of the United States or any state; and (ii) in original actions brought in the Cayman Islands, to impose liabilities against us predicated upon the civil liability provisions of the federal securities laws of the United States or any state, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, and or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands Court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

Special Considerations for Exempted Companies.    We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

Our Amended and Restated Memorandum and Articles of Association

Our amended and restated memorandum and articles of association contain certain requirements and restrictions that will apply to us until the consummation of our initial business combination. Our amended and restated memorandum and articles of association provide that, if we seek to amend our amended and restated memorandum and articles of association (A) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we do not complete our initial business combination within the completion window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity, we will provide public shareholders with the opportunity to redeem their public shares in connection with any such amendment. Our sponsor, officers and directors have agreed to waive any redemption rights with respect to any founder shares and any public shares held by them in connection with any such amendment. Specifically, our amended and restated memorandum and articles of association provide, among other things, that:

These provisions cannot be amended without the approval of a special resolution under Cayman Islands law, which requires the affirmative vote of shareholders holding at least two-thirds of our ordinary shares who, being entitled to do so, attend and vote, in person or by proxy, at a general meeting of the company. A quorum for such general meeting will consist of the holders present in person or by proxy of shares of the company representing a majority of the issued and outstanding shares entitled to vote at such general meeting.

Unless specified in our amended and restated memorandum and articles of association, or as required by applicable law or stock exchange rules, the affirmative vote of holders of a majority of the outstanding ordinary shares that are voted is required to approve any such matter voted on by our shareholders.

Certain Anti-Takeover Provisions of our Amended and Restated Memorandum and Articles of Association

Our authorized but unissued ordinary shares are available for future issuances without shareholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved ordinary shares could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Our amended and restated memorandum and articles of association contain provisions that may discourage unsolicited takeover proposals that shareholders may consider to be in their best interests. These provisions include the ability of the board of directors to designate the terms of and issue new series of preference shares, which may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our securities.

We are also subject to anti-takeover provisions under the Companies Act which could delay or prevent a change of control. Together these provisions may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our securities.

LISTING OF SECURITIES

Our units are listed on Nasdaq under the symbol “DMAAU” and, once the ordinary shares and rights begin separate trading, they are expected to be listed on Nasdaq under the symbols “DMAA” and “DMAAR,” respectively.
