Recent Developments

Warrant Inducement Agreement

On December 30, 2024, we entered into a letter agreement (the “Warrant Inducement Agreement”) with the holders (the “Investors”) of all of our outstanding warrants which provides the Investors with an opportunity to exercise such warrants to purchase Ordinary Shares, at a reduced exercise price and to receive additional Ordinary Shares upon exercise of such warrants, in each case prior to the Exercise Date (as defined below).

Under the Warrant Inducement Agreement, we agreed to reduce the exercise price per Ordinary Share issuable upon exercise of a Warrant (the “Warrant Share(s)”) for (i) the warrants issued in July 2023 (the “First Tranche Warrants”) to purchase Warrant Shares, (ii) the warrants issued in January 2024 (the “Second Tranche Warrants”) to purchase Warrant Shares, and (iii) the warrants issued in March 2024 (the “Third Tranche Warrants” and collectively with the First Tranche Warrants and the Second Tranche Warrants, the “Warrants”) to purchase Warrant Shares, in each case from $2.00 to $1.65 per Warrant Share payable in cash provided that the Investors exercise the Warrants on or prior to 5:00 p.m. (New York Time) on January 3, 2025 (the “Exercise Date”). In addition, under the terms of the Warrant Inducement Agreement, in the event that the Warrants are exercised by the Exercise Date, the number of Warrant Shares issuable upon the exercise of the Warrants shall be increased such that the aggregate exercise price payable upon the exercise of such Warrants after taking into account the decrease in exercise price of such Warrants shall be equal to the aggregate exercise price of such Warrants prior to such adjustment. As a result, if the First Tranche Warrants are exercised by the Exercise Date, the number of Warrant Shares issuable upon the timely exercise of the First Tranche Warrants will be 4,469,382 Warrant Shares; if the Second Tranche Warrants are exercised by the Exercise Date, the number of Warrant Shares issuable upon the timely exercise of the Second Tranche Warrants will be 3,033,159 Warrant Shares; if the Third Tranche Warrants are exercised by the Exercise Date, the number of Warrant Shares issuable upon timely exercise of the Third tranche Warrants will be 2,821,498 Warrant Shares.

With respect to the purchase of the Warrant Shares underlying the First Tranche Warrants, if no effective registration statement and current prospectus is available on or prior to 9:00 a.m. (New York Time) on January 3, 2025, the exercise price of the Warrant Shares underlying the First Tranche Warrants shall be further reduced to $1.30 per Warrant Share and the number of Warrant Shares issuable upon the exercise of the First Tranche Warrants shall be further increased such that the aggregate exercise price payable upon the exercise of such First Tranche Warrants after taking into account the additional decrease in exercise price of such First Tranche Warrants shall be equal to the aggregate exercise price of such First Tranche Warrants prior to such adjustment.

Under the Warrant Inducement Agreement, the Company and the Investors agreed to waive the obligations of the Company and the Investors as set forth in (i) Section 4.19 of the Securities Purchase Agreement, dated as of December 12, 2024, by and among the Company and the Investors, to close an additional convertible note tranche in an aggregate principal amount of $10.0 million pursuant to that certain securities purchase agreement, dated July 11, 2023, as amended, by January 16, 2025 (the “Note Tranche Closing”), and (ii) Section 4.15 in each of the Securities Purchase Agreements, dated as of December 12, 2024, December 16, 2024 and December 17, 2024, by and among the Company and the Investors.

All of the Warrants were exercised on or prior to the Exercise Date and as a result the Company issued 10,324,039 new Warrant Shares to the Investors.

Nasdaq Compliance

On December 26, 2024, we received formal written confirmation from The Nasdaq Stock Market, LLC (“Nasdaq”) confirming that the Company has regained compliance with Nasdaq’s minimum bid price requirement.

The regaining of compliance is a result of the Company’s closing bid price of the Ordinary Shares being at least $1.00 for at least 10 consecutive business days prior to January 28, 2025 deadline, as described in the initial notice from Nasdaq received by the Company on August 1, 2024.

The closing bid price of the Company’s Ordinary Shares has been at $1.00 per share or greater from December 11 to December 24, 2024. Accordingly, Nasdaq Listing Qualifications Staff has determined that the Company has regained compliance with Nasdaq Listing Rule 5550(a)(2), and the matter is now closed.

SEALCOIN

The responsibility for the development of the decentralized technology project “SEALCOIN” was transferred to our parent company, WISeKey, as of June 27, 2024. While the SEALCOIN project was originally under development by WISeKey and SEALSQ as a collaborative ‘proof of concept’ (with the aim of assessing the practical potential of the concept), the parties concluded that the SEALCOIN platform and tokens would be developed by WISeKey (capitalizing on WISeKey’s cybersecurity expertise), whereas SEALSQ is to focus on the development of the related semiconductor technology hardware and firmware (capitalizing on SEALSQ’s semiconductor and PKI expertise). The future role of SEALSQ in this project is expected to be as a supplier of secure semiconductors to or through SEALCOIN AG, a subsidiary of WISeKey, with SEALCOIN AG as a distributor of those chips to B2B participants in the platform SEALCOIN AG will be developing. Agreements between SEALSQ Corp and SEALCOIN AG are to be entered into reflecting the commercial terms and the Company anticipates that the terms of this contract will be negotiated on an arm’s length basis and that the Company would aim to be the preferred supplier of secure semiconductors to SEALCOIN AG.

RISK FACTORS

Investing in our securities involves significant risks. Before making an investment decision, you should carefully consider the risks described under “Risk Factors” in the applicable prospectus supplement and under “Item 3.D: Key Information—Risk Factors” in our most recent Annual Report on Form 20-F, or any updates in our Reports on Form 6-K, together with all of the other information appearing in this prospectus or incorporated by reference into this prospectus and any applicable prospectus supplement, in light of your particular investment objectives and financial circumstances.

The risks so described are not the only risks facing us. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. Our business, financial condition and results of operations could be materially adversely affected by any of these risks. The trading price of our securities could decline due to any of these risks, and you may lose all or part of your investment. The discussion of risks includes or refers to forward-looking statements; you should read the explanation of the qualifications and limitations on such forward-looking statements discussed elsewhere in this prospectus.

Delays in development, launch and/or rollout of our next-generation post-quantum cryptography products and services could have a material adverse effect on our business, results of operations and financial condition.

Our 2024 fiscal year end revenue was approximately $11 million, which represented a decline from $30 million reported for fiscal year end 2023. This decline was mainly due to our customers gradually shifting from our traditional microcontrollers to next generation post-quantum cryptography products and their delay of building inventory until the release of these new products. While we have expanded our revenue streams from Matter certification adoption and implementing new Cyber Trust Mark standards, our ability to generate and grow our revenues in the future will largely be dependent on our ability to develop our next-generation post-quantum cryptography products and services.

We currently expect to release our post-quantum cryptography products beginning in 2026. While we expect to recognize revenue in 2025 relating to the implementation of the new technologies into our planned Open Semiconductor and Test centers including the provision of professional services, we project to start to generate substantial returns from the full-scale commercial deployment of the post-quantum resistant chips starting in 2026. However, if we experience delays in the development and production of these products, it could have a material adverse effect on our business, results of operations and financial condition. Delays could result from either the “qualification” process, the “certification” process or both.

Our quantum-resistant chip is a newly developed product, and its qualification process is still ongoing. During this process, unforeseen issues may arise that require debugging and potentially a remask. Such adjustments could result in a delay of six to nine months in the chip’s market availability, impacting our ability to meet customer demand and production timelines.

In addition, the quantum-resistant chip is currently undergoing certification for FIPS 140-3 Level 3, Hardware (HW) Common Criteria certification, and Combination (HW+SW) Common Criteria certification. If the certification labs identify a critical flaw that prevents compliance with required security standards, we may need to partially redesign the affected components. This could significantly delay product availability for customers that require these certifications for deployment. Additionally, there is a risk of delays in the final certification process. Once the certification labs complete their testing and release the test report, there may be further delays in obtaining the FIPS certificate from NIST (the U.S. standards authority). Any such delays could postpone customer acceptance, impact sales cycles, and shift the anticipated production ramp-up schedule.

The quantum computing industry is in its early stages and is volatile, and if it does not develop, if it develops slower than we expect, if it develops in a manner that does not require use of our post-quantum cryptography products and services, if it encounters negative publicity or if our post-quantum cryptography products and services do not drive commercial engagement, the growth of our business will be harmed.

The nascent market for quantum computers is still rapidly evolving, characterized by rapidly changing technologies, competitive pricing and competitive factors, evolving government regulation and industry standards, and changing customer demands and behaviors. If the market for quantum computers in general does not develop as expected, or develops more slowly than expected, our business, prospects, financial condition and operating results could be harmed.

In addition, our growth and future demand for our products is highly dependent upon the adoption by developers and customers of quantum computing. Negative publicity concerning our post-quantum cryptography products and services or the quantum computing industry as a whole could limit market acceptance of our products. If our customers do not perceive the benefits of our post-quantum cryptography products and services, or if our post-quantum cryptography products and services do not drive customer engagement, then our market may not develop at all, or it may develop more slowly than we expect. If any of these events occur, it could have a material adverse effect on our business, financial condition or results of operations.

Our business could suffer as a result of tariffs and trade sanctions or similar actions.

The imposition by the United States of tariffs, sanctions or other restrictions on goods exported from the United States or imported into the United States or countermeasures imposed in response to such government actions could adversely affect our operations or our ability to sell our products globally, which could adversely affect our operating results and financial condition. Recently, U.S. government leaders have increased their frequency of discussion of the imposition of stronger tariffs, sanctions, and other restrictions on goods exported from the United States or imported into the United States, and non-U.S. government leaders have increased their discussion of countermeasures. For example, in February 2025, the United States announced a proposed 25% tariff on imports of all semiconductor chips into the United States. As of February 2025, the U.S. executive order contains provisions allowing for further increases in the scope and amount of tariffs in the event of retaliatory countermeasures, and the future of existing tariffs, and the possibility for new tariffs, remains very uncertain. Although a large amount of our supply chain does not currently directly import products to the United States as we supply to contract manufacturers outside the United States, there is a possibility that any future tariffs may still impact upon our ability to sell our product and to remain competitive in the market. Such escalations in these trade measures may directly impair our business by increasing trade-related costs or disrupting established supply chains and may indirectly impair our business by causing a negative effect on global economic conditions and financial markets. The ultimate impact of these trade measures is uncertain and may be affected by various factors, including whether and when such trade measures are implemented, the timing when such measures may become effective, and the amount, scope, or nature of such trade measures.

Additional changes or threatened changes in U.S. trade measures have affected and may continue to affect trade involving additional countries as well, including Mexico, Canada, Colombia, Taiwan, the United Kingdom, and the member countries of the European Union. Each of these measures or threatened measures may instigate reciprocal countermeasures by affected countries, potentially accelerating further increases in trade measures. Significant new tariffs scheduled to be imposed by the United States on imports of Mexican and Canadian origin goods have been temporarily delayed pending further negotiations between these countries. If the United States and Mexico or the United States and Canada are unable to reach long-term agreements, or if the President were to impose significant new tariffs against the European Union, Taiwan, or any other country or countries, the macroeconomic effect of any such tariffs could be significant. The tariff threatened against Taiwan may specifically target imports of semiconductor products, which, if imposed, could seriously and negatively affect our business and the U.S. economy overall. The materials subject to these tariffs may impact the cost or availability of raw materials used by our suppliers or in our customers’ products. The imposition of further tariffs by the United States on a broader range of imports, or further retaliatory trade measures taken in response to additional tariffs, could increase costs in our supply chain or reduce demand of our customers’ products, either of which could adversely affect our results of operations. Any increase in trade-related costs associated with such measures may impair the profitability of such international production, may strain our suppliers’ ability to reliably provide inputs necessary to produce these items, and may otherwise affect our partners’ abilities to provide our products at previously contracted prices. Our business and financial results could be negatively affected as a result.

Our stock price has been and may continue to be volatile.

The market price of our Ordinary Shares has been, and is likely to continue to be, volatile. The variance in our stock price makes it difficult to forecast the stock price at which an investor may be able to buy or sell Ordinary Shares. The market price for our Ordinary Shares could be subject to fluctuations as a result of factors that are out of our control, such as:

actual or anticipated variations in our results of operations;

general conditions and trends in the semiconductor industry; and

general economic, political and market conditions.

An active trading market for our Ordinary Shares may not be sustained.

Although our Ordinary Shares are listed on the Nasdaq Stock Market, LLC, the market for our Ordinary Shares has demonstrated varying levels of trading activity. The current level of trading may not be sustained in the future. The lack of an active market for our Ordinary Shares may impair investors’ ability to sell their Ordinary Shares at the time they wish to sell them or at a price that they consider reasonable, may reduce the fair market value of their Ordinary Shares and may impair our ability to raise capital to continue to fund operations by selling Ordinary Shares and may impair our ability to acquire additional assets by using our Ordinary Shares as consideration.

DESCRIPTION OF ORDINARY SHARES

The following description of our share structure is a summary of the material terms of our amended and restated memorandum and articles of association and BVI corporate law regarding our shares and the holders thereof. This description contains all material information concerning our shares but does not purport to be complete.

General

We are a British Virgin Islands Business Company (company number 2095496) and our affairs are governed by our memorandum and articles of association (“Articles”), the BVI Business Companies Act (“BVI Act”) and common law of the British Virgin Islands. Based upon the Articles, we are authorized to issue a maximum of 210,000,000 shares in two classes as follows:

(a)

200,000,000 Ordinary Shares with a par value of USD 0.01 per share (“Ordinary Shares”); and

(b)

10,000,000 Class F Shares with a par value of USD 0.05 per share (“Class F Shares”).

As of the date of this prospectus, 104,508,901 Ordinary Shares are issued and outstanding and 1,499,800 Class F Shares are issued and outstanding. No preferred shares are issued or outstanding or authorized by our Articles. The following description summarizes the material terms of our shares as set out more particularly in our Articles. Because it is only a summary, it may not contain all the information that is important to you.

Share Rights

Each Ordinary Share confers upon the shareholder:

(a)

the right to attend any meeting of shareholders;

(b)

the right to one vote per Ordinary Share on any resolution of shareholders as against each other Ordinary Share but, as a class, the Ordinary Shares shall retain 50.01% of the Company’s voting power;

(c)

the right to an equal share in any dividend paid by the Company against each other Ordinary Share, which shall be one fifth of any amount paid by the Company against each Class F Share but which shall not rank in preference or be subordinate to any other share;

(d)

the right to an equal share in the distribution of the surplus assets of the Company against each other Ordinary Share, which shall be one fifth of any amount paid by the Company against each Class F Share but which shall not rank in preference to any other share; and

(e)

such other rights and entitlements as may be specified in the Articles.

Our Ordinary Shareholders have no conversion, pre-emptive or other subscription rights and there are no sinking fund or redemption provisions applicable to the Ordinary Shares.

Each Class F Share confers upon the shareholder:

(a)

the right to attend any meeting of shareholders;

(b)

a number of votes per Class F Share, on any matter that is submitted to a vote of shareholders, that would cause the total votes of all Class F Shares to equal 49.99% of the voting power of all shares (or, if the applicable voting standard is “a majority of the shares present in person or represented by proxy and entitled to vote on such matter”, 49.999999% of the voting power of shares present in person or represented by proxy and entitled to vote on such matter);

(c)

the right to an equal share in any dividend paid by the Company against each other Class F Shares, and which shall be five times greater than any amount paid by the Company against each Ordinary Share but which shall not rank in preference to any other share; and

(d)

the right to an equal share in the distribution of the surplus assets of the Company against each other Class F Shares, and which shall be five times greater than any amount paid by the Company against each Ordinary Share but which shall not rank in preference to any other share.

The Class F Shares are subject to mandatory and automatic redemption, in the event of a change of control (being the acquisition by any person or entity, alone or jointly, of more than 50% of the voting rights of any Class F Shareholder which is a corporate entity), as determined by the Company’s board of directors, in exchange for the issuance of new Ordinary Shares at a ratio of five (5) Ordinary Shares for each one (1) Class F Share redeemed.

The Class F Shares are non-transferable.

The Company and the holders of the Class F Shares have entered into a Class F Shareholders’ Agreement that provides, among other things, that the holders of Class F Shares:

will vote the Class F Shares held by them as one and in accordance with the majority (by the number of shares held) view of the holders of the Class F Shares; and

are bound by the redemption provisions set out in the Articles and that they will take all necessary action to comply with them.

Register of Members

Under the BVI Act, the shares are deemed to be issued when the name of the shareholder is entered in the register of members. Our register of members will be maintained by our transfer agent, Computershare Inc.

If:

(a)

information that is required to be entered in the register of members is omitted from the register or is inaccurately entered in the register; or

(b)

there is unreasonable delay in entering information in the register,

a shareholder of the company, or any person who is aggrieved by the omission, inaccuracy or delay, may apply to the British Virgin Islands Courts for an order that the register be rectified, and the court may either refuse the application or order the rectification of the register, and may direct the Company to pay all costs of the application and any damages the applicant may have sustained.

Dividends

We have not paid any cash dividends on our shares to date. The payment of cash dividends in the future will be dependent upon our revenues and earnings. Under the laws of the British Virgin Islands and our Articles, we may only pay a dividend or make a distribution to our shareholders if, following such dividend or distribution, the value of our assets will exceed our liabilities and we will be able to pay our debts as they fall due. In addition, the Second Tranche Notes prohibit us and our subsidiaries from paying dividends or other cash distributions, except for intercompany transfers to us and payments to WISeKey.

Comparison of Shareholder Rights

DELAWARE CORPORATE LAW

BVI CORPORATE LAW

Class actions and derivative actions generally are available to shareholders of a Delaware corporation for, among other things, breach of fiduciary duty, corporate waste and actions not taken in accordance with applicable law. In such actions, the court has discretion to permit the winning party to recover attorneys’ fees incurred in connection with such action.

Class actions and derivative actions are generally not available to shareholders under British Virgin Islands law.

The British Virgin Islands courts, however, would ordinarily be expected to permit a shareholder to commence an action in the name of a company to remedy a wrong to the company where the act complained of is alleged to be beyond the corporate power of the company or illegal, or would result in the violation of the company’s memorandum and articles of association. Furthermore, consideration would be given by a British Virgin Islands court to acts that are alleged to constitute a fraud against the minority shareholders or, for instance, where an act requires the approval of a greater percentage of the company’s shareholders than that which actually approved it.

When the affairs of a company are being conducted in a manner which is oppressive or prejudicial to the interests of some part of the shareholders, one or more shareholders may apply to the High Court of the British Virgin Islands, which may make such order as it sees fit, including an order regulating the conduct of the company’s affairs in the future or ordering the purchase of the shares of any shareholders by other shareholders or by the company.

DELAWARE CORPORATE LAW	BVI CORPORATE LAW
Under the Delaware General Corporation Law, the board of directors has the authority to fix the compensation of directors, unless otherwise restricted by the certificate of incorporation or bylaws.	The Articles contain a provision that the board of directors has the power to determine the remuneration, if any, of the directors.
Unless directors are elected by written consent in lieu of an annual meeting, directors are elected in an annual meeting of stockholders on a date and at a time designated by or in the manner provided in the bylaws. Re-election is possible. Classified boards are permitted.	The Articles provide that the directors shall be appointed at the Company’s annual general meeting and will hold office until the next annual general meeting or until their earlier death, resignation or removal. Re-election is possible. The directors of the Company may appoint directors where there is a vacancy.
The Delaware General Corporation Law provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of directors (but not other controlling persons) of the corporation for monetary damages for breach of a fiduciary duty as a director, except no provision in the certificate of incorporation may eliminate or limit the liability of a director for: · any breach of a director’s duty of loyalty to the corporation or its shareholders; · acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; · statutory liability for unlawful payment of dividends or unlawful stock purchase or redemption; or · any transaction from which the director derived an improper personal benefit. A Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any proceeding, other than an action by or on behalf of the corporation, because the person is or was a director or officer, against liability incurred in connection with the proceeding if the director or officer acted in good faith and in a manner reasonably believed to be in, or not opposed to, the best interests of the corporation; and the director or officer, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Unless ordered by a court, any foregoing indemnification is subject to a determination that the director or officer has met the applicable standard of conduct: · by a majority vote of the directors who are not parties to the proceeding, even though less than a quorum; · by a committee of directors designated by a majority vote of the eligible directors, even though less than a quorum; · by independent legal counsel in a written opinion if there are no eligible directors, or if the eligible directors so direct; or ·  by the shareholders. Moreover, a Delaware corporation may not indemnify a director or officer in connection with any proceeding in which the director or officer has been adjudged to be liable to the corporation unless and only to the extent that the court determines that, despite the adjudication of liability but in view of all the circumstances of the case, the director or officer is fairly and reasonably entitled to indemnity for those expenses which the court deems proper.	Section 132 of the BVI Act, and the Articles, provide that, subject to certain limitations, SEALSQ shall indemnify its directors and officers against all expenses, including legal fees, and against all judgments, fines and amounts paid in settlement and reasonably incurred in connection with legal, administrative or investigative proceedings. Such indemnity only applies if the person acted honestly and in good faith with a view to the best interests of the company and, in the case of criminal proceedings, the person had no reasonable cause to believe that their conduct was unlawful. Section 133 of the BVI Act permits a company to purchase and maintain insurance for the benefit of any officer or director in respect of any loss or liability attaching to them in respect of any negligence, default, breach of duty or breach of trust, whether or not we may otherwise indemnify such officer or director.

DELAWARE CORPORATE LAW

BVI CORPORATE LAW

A director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components:

· the duty of care; and

· the duty of loyalty.

The BVI Act imposes a duty on directors and officers of a British Virgin Islands company:

(a) to act honestly and in good faith and in what the director believes to be in the best interests of the company when exercising their powers as a director;

(b) to exercise the reasonable care, diligence, and skill that a reasonable director would exercise in the same circumstances taking into account, but without limitation:

i. the nature of the company;

ii.  the nature of the decision; and

iii.  the position of the director and the nature of their responsibilities;

(c) to exercise their duties for proper purpose and in accordance with the BVI Act and the memorandum and association of the company; and

(d)   to disclose any interest which they have in a transaction entered into or to be entered into by the company.

The statutory duties imposed on directors, by the BVI Act, are further supplemented by common law duties established (over centuries) of case law. There is considerable overlap between the common law and the BVI Act and in most circumstances it is not necessary to consider the two separately.

In addition, the BVI Act imposes various duties on directors and officers of a company with respect to certain matters of management and administration of the company.

The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he reasonably believes to be in the best interests of the corporation. He must not use his corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence a breach of one of the fiduciary duties.

Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

The BVI Act also imposes a duty on directors and officers of a British Virgin Islands company to:

(a) act honestly and in good faith with a view to the best interests of the company; and

(b) exercise the care, diligence and skill that a reasonable director or officer would exercise in the same circumstances.

In addition, the BVI Act imposes various duties on directors and officers of a company with respect to certain matters of management and administration of the company.

DELAWARE CORPORATE LAW	BVI CORPORATE LAW
A Delaware corporation may, in its certificate of incorporation, eliminate the right of shareholders to act by written consent.	The BVI Act provides that shareholders may take action by written consent. Under the Articles a resolution in writing is passed when it is signed by the shareholders of the Company who at the date of the notice of the resolution represent such majority of votes of shares as would be entitled to vote on such resolution.
A shareholder of a Delaware corporation has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.	Under the Articles, shareholders entitled to exercise 30% or more of the voting rights, in respect of the matter for which the meeting is requested, can require the directors to convene a meeting of shareholders.
Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation provides for it.	Under British Virgin Islands law, the voting rights of shareholders are regulated by the company’s memorandum and articles of association and, in certain circumstances, by the BVI Act. The Articles do not provide for cumulative voting.
A Delaware corporation with a classified board may be removed only for cause with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise.	Under the Articles, a director may be removed: (a) with or without cause, by resolution of shareholders passed at a meeting of shareholders called for the purpose of removing the director or for purposes including the removal of the director or by a written resolution passed by at least 75% of the votes of the shares entitled to vote; or (b) with cause, by resolution of directors passed by all directors other than the director being removed at a meeting of directors called for the purpose of removing the director or for purposes including the removal of the director.
The Delaware General Corporation Law generally prohibits a Delaware corporation from engaging in certain business combinations with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or group who or which owns or owned 15.0% or more of the corporation’s outstanding voting stock within the past three years.	There is no similar law in the British Virgin Islands.
Unless the board of directors of a Delaware corporation approves the proposal to dissolve, dissolution must be approved by shareholders holding 100.0% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board.	As permitted by the BVI Act and our Articles, we may be voluntarily liquidated under Part XII of the BVI Act by resolution of directors or resolution of shareholders if we have no liabilities or we are able to pay our debts as they fall due and the value of our assets equals or exceeds our liabilities. A company may also be wound up where a court deems it just and equitable to do so and in circumstances where they are insolvent in accordance with the terms of the BVI Insolvency Act.

DELAWARE CORPORATE LAW	BVI CORPORATE LAW
A Delaware corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise.	Under the Articles, the rights conferred upon the holders of our shares of any class may only be varied with the consent in writing of the holders of a majority of the issued shares of that class or by a resolution approved at a meeting of the shares of that class by the affirmative vote of a majority of the votes of the shares of that class which were present at the meeting and were voted.
A Delaware corporation’s governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise.	A British Virgin Islands company’s memorandum and articles of association may be amended by resolutions of the board of directors and the shareholders, subject to the BVI Act and the memorandum and articles of association.
Shareholders of a Delaware corporation, upon written demand under oath stating the purpose thereof, have the right during the usual hours for business to inspect for any proper purpose, and to obtain copies of list(s) of shareholders and other books and records of the corporation and its subsidiaries, if any, to the extent the books and records of such subsidiaries are available to the corporation.	Under the BVI Act, members of the general public, on payment of a nominal fee, can obtain copies of the public records of a company available at the office of the BVI Registrar which will include the company’s certificate of incorporation, its memorandum and articles of association (with any amendments), a list of the current directors and records of license fees paid to date and will also disclose any articles of dissolution, articles of merger and a register of charges if the company has elected to file such a register. A shareholder of a company is entitled, on giving written notice to the company, to inspect: (a) the memorandum and articles; (b) the register of members; (c) the register of directors; and (d) the minutes of meetings and resolutions of members and of those classes of members of which they are a member, and to make copies of or take extracts from the documents and records referred to above. Subject to the memorandum and articles of association, the directors may, if they are satisfied that it would be contrary to the company’s interests to allow a member to inspect any document, or part of a document, specified above, refuse to permit the member to inspect the document or limit the inspection of the document, including limiting the making of copies or the taking of extracts from the records. Where a company fails or refuses to permit a member to inspect a document or permits a member to inspect a document subject to limitations, that member may apply to a British Virgin Islands Court for an order that they should be permitted to inspect the document or to inspect the document without limitation.

DELAWARE CORPORATE LAW	BVI CORPORATE LAW
The board of directors may approve a dividend without shareholder approval. Subject to any restrictions contained in its certificate of incorporation, the board may declare and pay dividends upon the shares of its capital stock either: · out of its surplus, or · in case there is no such surplus, out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. Stockholder approval is required to authorize capital stock in excess of that provided in the charter. Directors may issue authorized shares without stockholder approval.	Under British Virgin Islands law, the board of directors may declare a dividend without shareholder approval, but a company may not declare or pay dividends if there are reasonable grounds for believing that: (a) the company is, or would after the payment be, unable to pay its debts as they fall due; or (b)  that the value of the company’s assets would be less than its liabilities.
All creation of shares require the board of directors to adopt a resolution or resolutions, pursuant to authority expressly vested in the board of directors by the provisions of the company’s certificate of incorporation.	The number of shares that a British Virgin Islands company is authorized to issue is set out in the memorandum and articles of association. The Articles provide that the company is authorized to issue 210,000,000 shares in two classes as follows: (a) 200,000,000 Ordinary Shares; and (b) 10,000,000 Class F Shares.
Under the Delaware General Corporation Law, with certain exceptions, a merger, consolidation, sale, lease or transfer of all or substantially all of the assets of a corporation must be approved by the board of directors and a majority of the outstanding shares entitled to vote thereon. A shareholder of a Delaware corporation participating in certain major corporate transactions may, under certain circumstances, be entitled to appraisal rights pursuant to which such shareholder may receive cash in the amount of the fair value of the shares held by such shareholder (as determined by a court) in lieu of the consideration such shareholder would otherwise receive in the transaction. The Delaware General Corporation Law also provides that a parent corporation, by resolution of its board of directors, may merge with any subsidiary, of which it owns at least 90.0% of each class of capital stock without a vote by the shareholders of such subsidiary. Upon any such merger, dissenting shareholders of the subsidiary would have appraisal rights.	The consolidation or merger of a British Virgin Islands company with another company or corporation (other than certain affiliated companies) requires the consolidation or merger to be approved by the company’s board of directors and by its shareholders. Unless the company’s memorandum and articles of association provide otherwise, the approval of a majority of the shareholders voting at a meeting of shareholders is required to approve the consolidation or merger agreement. Under British Virgin Islands law, in the event of a consolidation or merger of a British Virgin Islands company with another company or corporation, a shareholder of the British Virgin Islands company who did not vote in favor of the amalgamation or merger and who is not satisfied that fair value has been offered for such shareholder’s shares may seek fair value for those shares in accordance with Section 179 of the BVI Act.

DESCRIPTION OF WARRANTS

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the warrants that we may offer under this prospectus and the related warrant agreements and warrant certificates. While the terms summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe the particular terms of any series of warrants that we may offer in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any warrants offered under that prospectus supplement may differ from the terms described below. However, no prospectus supplement shall fundamentally change the terms that are set forth in this prospectus or offer a security that is not registered and described in this prospectus at the time of its effectiveness. Specific warrant agreements will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement that includes this prospectus or as an exhibit to a report filed under the Exchange Act.

General

The applicable prospectus supplement will describe the terms of the warrants, including as applicable:

the offering price;

the aggregate number or amount of underlying securities purchasable upon exercise of the warrants and the exercise price;

the number of warrants being offered;

the date, if any, after which the warrants and the underlying securities will be transferable separately;

the date on which the right to exercise the warrants will commence, and the date on which the right will expire;

the number of warrants outstanding, if any;

any material BVI and/or U.S. federal income tax consequences;

the terms, if any, on which we may accelerate the date by which the warrants must be exercised; and

any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

Warrants will be offered and exercisable for U.S. dollars only and will be in registered form only.

Holders of warrants will be able to exchange warrant certificates for new warrant certificates of different denominations, present warrants for registration of transfer, and exercise warrants at the designated office of the warrant agent in the applicable prospectus supplement. Prior to the exercise of any warrants, holders of the warrants to purchase Ordinary Shares will not have any rights of holders of Ordinary Shares, including the right to receive payments of dividends, if any, or to exercise any applicable right to vote.

Certain Risk Considerations

Any warrants we issue will involve a degree of risk, including risks arising from fluctuations in the price of the underlying Ordinary Shares and general risks applicable to the securities market (or markets) on which the underlying securities trade, as applicable. Prospective purchasers of the warrants will need to recognize that the warrants may expire worthless, and, thus, purchasers should be prepared to sustain a total loss of the purchase price of their warrants. This risk reflects the nature of a warrant as an asset that, other factors held constant, tends to decline in value over time and that may, depending on the price of the underlying securities, become worthless when it expires. The trading price of a warrant at any time is expected to increase if the price of or, if applicable, the dividend rate on, the underlying securities increases. Conversely, the trading price of a warrant is expected to decrease as the time remaining to expiration of the warrant decreases and as the price of or, if applicable, the dividend rate on, the underlying securities, decreases. Assuming all other factors are held constant, the more a warrant is “out-of-the-money” (i.e., the more the exercise price exceeds the price of the underlying securities and the shorter its remaining term to expiration), the greater the risk that a purchaser of the warrant will lose all or part of his or her investment. If the price of the underlying securities does not rise before the warrant expires to an extent sufficient to cover a purchaser’s cost of the warrant, the purchaser will lose all or part of his or her investment in the warrant upon expiration.

In addition, prospective purchasers of the warrants should be experienced with respect to options and option transactions, should understand the risks associated with options and should reach an investment decision only after careful consideration, with their financial advisers, of the suitability of the warrants in light of their particular financial circumstances and the information discussed in this prospectus and, if applicable, the prospectus supplement. Before purchasing, exercising or selling any warrants, prospective purchasers and holders of warrants should carefully consider, among other things:

the trading price of the warrants;

the price of the underlying securities at that time;

the time remaining to expiration; and

any related transaction costs.

Some of the factors referred to above are in turn influenced by various political, economic and other factors that can affect the trading price of the underlying securities and should be carefully considered prior to making any investment decisions.

Purchasers of the warrants should further consider that the initial offering price of the warrants may be in excess of the price that a purchaser of options might pay for a comparable option in a private, less liquid transaction. In addition, it is not possible to predict the price at which the warrants will trade in the secondary market or whether any such market will be liquid. We may, but will not be obligated to, file an application to list any warrants on a U.S. national securities exchange. To the extent that any warrants are exercised, the number of warrants outstanding will decrease, which may result in a lessening of the liquidity of the warrants. Finally, the warrants will constitute our direct, unconditional and unsecured obligations and, as such, will be subject to any changes in our perceived creditworthiness.

Exercise of Warrants

Each holder of a warrant will be entitled to purchase that number or amount of underlying securities, at the exercise price, as will in each case be described in the prospectus supplement relating to the offered warrants. After the close of business on the warrant expiration date (which may be extended by us), unexercised warrants will become void.

Holders may exercise warrants by delivering to the warrant agent payment as provided in the applicable prospectus supplement of the amount required to purchase the underlying securities purchasable upon exercise, together with the information set forth on the reverse side of the warrant certificate. Warrants will be deemed to have been exercised upon receipt of payment of the exercise price, subject to the receipt of the warrant certificate evidencing the exercised warrants. Upon receipt of payment and the warrant certificate properly completed and duly executed at the designated office of the warrant agent in the applicable prospectus supplement, we will, as soon as practicable, issue and deliver the underlying securities purchasable upon such exercise. If fewer than all of the warrants represented by a warrant certificate are exercised, we will issue a new warrant certificate for the remaining amount of warrants.

Amendments and Supplements to Warrant Agreements

We may amend or supplement the warrant agreement without the consent of the holders of the warrants issued under the agreement to effect changes that are not inconsistent with the provisions of the warrants and that do not adversely affect the interests of the holders of warrants.

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase our Ordinary Shares. These subscription rights may be issued independently or together with any other security offered hereby and may or may not be transferable by the shareholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

The prospectus supplement relating to any subscription rights we offer, if any, will, to the extent applicable, include specific terms relating to the offering, including some or all of the following:

the price, if any, for the subscription rights;

the exercise price payable for each Ordinary Share upon the exercise of the subscription rights;

the number of subscription rights to be issued to each shareholder;

the number and terms of the Ordinary Shares which may be purchased per each subscription right;

the extent to which the subscription rights are transferable;

any other terms of the subscription rights, including the terms, procedures and limitations relating to the exchange and exercise of the subscription rights;

the date on which the right to exercise the subscription rights shall commence, and the date on which the subscription rights shall expire;

the extent to which the subscription rights may include an over-subscription privilege with respect to unsubscribed securities; and

if applicable, the material terms of any standby underwriting or purchase arrangement which may be entered into by us in connection with the offering of subscription rights.

The description in the applicable prospectus supplement of any subscription rights we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable subscription right agreement, which will be filed with the SEC if we offer subscription rights. For more information on how you can obtain copies of the applicable subscription right agreement if we offer subscription rights, see “Where You Can Find More Information” below and “Incorporation of Certain Documents by Reference” below. We urge you to read the applicable subscription right agreement and any applicable prospectus supplement in their entirety.

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

The applicable prospectus supplement will describe:

the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

the material terms of a unit agreement under which the units will be issued;

any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and

whether the units will be issued in fully registered or global form.

The applicable prospectus supplement will describe the terms of any units. The preceding description and any description of units in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the unit agreement and, if applicable, collateral arrangements and depositary arrangements relating to such units. For more information on how you can obtain copies of the applicable unit agreement if we offer units, see “Where You Can Find More Information” below and “Incorporation of Certain Documents by Reference” below. We urge you to read the applicable unit agreement and any applicable prospectus supplement in their entirety.

TAXATION

The material BVI and U.S. federal income tax consequences relating to the purchase, ownership and disposition of any of the securities offered by this prospectus will be set forth in the applicable prospectus supplement offering those securities or incorporated by reference from our Annual Report on Form 20-F or other public filings we make with the SEC.

SELLING SHAREHOLDERS

Selling shareholders are persons or entities that, directly or indirectly, have acquired or will from time to time acquire from us, our securities. If the registration statement of which this prospectus forms a part is used by selling shareholders for the resale of any securities registered thereunder, we will provide you with a prospectus supplement, which will set forth the name of each selling shareholder, the number of securities beneficially owned by such selling shareholder and the number of securities they are offering. The prospectus supplement also will disclose whether any of the selling shareholders have held any position or office with, have been employed by or otherwise have had a material relationship with us during the three years prior to the date of the prospectus supplement.

PLAN OF DISTRIBUTION

We may sell the securities described in this prospectus through underwriters or dealers, through agents, directly to one or more purchasers, “at-the-market” offerings, negotiated transactions, block trades or through a combination of these methods. The applicable prospectus supplement will describe the terms of the offering of the securities, including:

●

the name or names of any underwriters, if any, and if required, any dealers or agents, and the amount of securities underwritten or purchased by each of them, if any;

●

the public offering price or purchase price of the securities from us and the net proceeds to us from the sale of the securities;

●

any underwriting discounts and other items constituting underwriters’ compensation;

●

any discounts or concessions allowed or re-allowed or paid to dealers; and

●

any securities exchange or market on which the securities may be listed.

We may distribute the securities from time to time in one or more transactions at:

●

a fixed price or prices, which may be changed;

●

market prices prevailing at the time of sale;

●

varying prices determined at the time of sale related to such prevailing market prices; or

●

negotiated prices.

Only underwriters named in the prospectus supplement will be underwriters of the securities offered by the prospectus supplement.

If we use underwriters in the sale, the underwriters will either acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale, or sell the securities on a “best efforts, minimum/maximum basis” when the underwriters agree to do their best to sell the securities to the public. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may change from time to time.

If we use a dealer in the sale of the securities being offered pursuant to this prospectus or any prospectus supplement, the securities will be sold directly to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

Our ordinary shares are listed on the Nasdaq Capital Market. Unless otherwise specified in the related prospectus supplement, all securities we offer, other than ordinary shares, will be new issues of securities with no established trading market. Any underwriter may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We may apply to list securities that we offer on an exchange, but we are not obligated to do so. Therefore, there may not be liquidity or a trading market for any series of securities.

We may sell the securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we may pay the agent in the applicable prospectus supplement.

We may authorize agents or underwriters to solicit offers by institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the applicable prospectus supplement.

In connection with the sale of the securities, underwriters, dealers or agents may receive compensation from us or from purchasers of the securities for whom they act as agents in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of the securities, and any institutional investors or others that purchase securities directly and then resell the securities, may be deemed to be underwriters, and any discounts or commissions received by them from us and any profit on the resale of the securities by them may be deemed to be underwriting discounts and commissions under the Securities Act of 1933.

Certain legal matters with respect to British Virgin Islands law in connection with this offering are being passed upon for us by Harney Westwood & Riegels LP. Certain matters of U.S. federal and New York law are being passed upon for us by Patterson Belknap Webb & Tyler LLP, New York, New York.

We will also incorporate by reference all subsequent Annual Reports on Form 20-F that we file with the SEC. In addition, we will incorporate by reference certain future materials furnished to the SEC on Form 6-K after the date of the initial registration statement, but only to the extent specifically indicated in those submissions or in a future prospectus supplement. Each subsequently filed Annual Report should be deemed to supersede entirely each earlier filed Annual Report and the materials furnished on an earlier Form 6-K and, unless explicitly stated otherwise, such earlier reports should not be deemed to be part of this prospectus or any accompanying prospectus supplement and you should not rely upon statements made in those earlier periodic reports.

The information relating to us contained in this prospectus is not comprehensive and should be read together with the information contained in the incorporated documents. Descriptions contained in the incorporated documents as to the contents of any contract or other document may not contain all of the information which is of interest to you. You should refer to the copy of such contract or other document filed as an exhibit to our filings.

WHERE YOU CAN FIND MORE INFORMATION

We have filed with the SEC a registration statement on Form F-3 under the Securities Act, relating to this offering of securities. As permitted by SEC rules, this prospectus does not contain all of the information contained in the registration statement of which this prospectus forms a part. Statements made in this prospectus concerning the contents of any contract, agreement or other document are summaries of all material information about the documents summarized, but are not complete descriptions of all terms of these documents. If we filed any of these documents as an exhibit to the registration statement, you may read the document itself for a complete description of its terms.

We are subject to the informational requirements of the Exchange Act applicable to foreign private issuers. In accordance with the Exchange Act, we file reports, including annual reports on Form 20-F containing financial statements audited by an independent accounting firm. We also furnish to the SEC, under cover of Reports of Foreign Private Issuer on Form 6-K, material information required to be made public by us or filed by us with and made public by any stock exchange or distributed by us to our shareholders. Such reports and other information filed with the SEC are available to the public over the internet at the SEC’s website at http://www.sec.gov. We also generally make available on our own website (www.sealsq.com) our half-year and year-end financial statements as well as other information.

As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements to shareholders, and our officers, directors and principal shareholders are exempt from the “short-swing profits” reporting and liability provisions contained in Section 16 of the Exchange Act and related Exchange Act rules. In addition, we are not required under the Exchange Act to file periodic reports and financial statements as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act.

We maintain a corporate website at www.sealsq.com. Information contained on, or that can be accessed through, our website does not constitute a part of this prospectus. We have included our website address in this prospectus solely as an inactive textual reference.

ENFORCEABILITY OF CIVIL LIABILITIES

We are incorporated under the laws of the British Virgin Islands and our principal executive offices are located outside the United States. Most of our directors and officers and those of our subsidiaries are residents of countries other than the United States. Substantially all of our and our subsidiaries’ assets and a substantial portion of the assets of our directors and officers are located outside the United States. As a result, it may be difficult or impossible for United States investors to effect service of process within the United States upon us, our directors or officers or our subsidiaries, or to realize against us or them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States.

Furthermore, there is substantial doubt that courts in jurisdictions outside the U.S. (i) would enforce judgments of U.S. courts obtained in actions against us or our directors or officers based upon the civil liability provisions of applicable U.S. federal and state securities laws or (ii) would enforce, in original actions, liabilities against us or our directors or officers based on those laws.

PROSPECTUS

PART II: INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 8. Indemnification of Directors and Officers

The Articles provide that, subject to certain limitations, the Company shall indemnify its directors and officers against all expenses, including legal fees, and against all judgments, fines and amounts paid in settlement and reasonably incurred in connection with legal, administrative or investigative proceedings. Such indemnity is only permitted under the BVI Act and the Articles if the person acted honestly and in good faith with a view to the best interests of the Company and, in the case of criminal proceedings, the person had no reasonable cause to believe that their conduct was unlawful. The decision of the directors as to whether the person acted honestly and in good faith and with a view to the best interests of the Company and as to whether the person had no reasonable cause to believe that their conduct was unlawful, is, in the absence of fraud, sufficient for the purposes of the Articles, unless a question of law is involved. The termination of any proceedings by any judgment, order, settlement, conviction or the entering of a nolle prosequi does not, by itself, create a presumption that the person did not act honestly and in good faith and with a view to the best interests of the Company or that the person had reasonable cause to believe that their conduct was unlawful.

The Company has entered into agreements with its officers and directors to provide contractual indemnification in addition to the indemnification provided for in the Articles. The Articles also permit the Company to purchase and maintain insurance on behalf of any officer or director who at the request of the Company is or was serving as a director or officer of, or in any other capacity is or was acting for, another company or a partnership, joint venture, trust or other enterprise, against any liability asserted against the person and incurred by the person in that capacity, whether or not the Company has or would have had the power to indemnify the person against the liability as provided in the Articles. The Company has purchased a policy of directors’ and officers’ liability insurance that insures the Company’s officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures the Company against its obligations to indemnify the Company’s officers and directors.

These provisions may discourage shareholders from bringing a lawsuit against the Company’s directors for breach of their statutory or fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against officers and directors, even though such an action, if successful, might otherwise benefit the Company and the shareholders. Furthermore, a shareholder’s investment may be adversely affected to the extent the Company pays the costs of settlement and damage awards against officers and directors pursuant to these indemnification provisions.

The Company believes that these provisions, the insurance and the indemnity agreements are reasonable and necessary to attract and retain talented and experienced officers and directors.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

The index to exhibits appears below on the page immediately following the signature pages of this Registration Statement.

Item 10. Undertakings

(a)

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales of securities are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i), (a)(1) (ii), and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering.

Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act of 1933, or Rule 3-19 of Regulation S- X if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

(5)

That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i)

If the registrant is relying on Rule 430B:

(a) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(b) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

II-2

(ii) If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(6) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about, prepared by or on behalf of, the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s Annual Report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s Annual Report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(h) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

Dear SEALSQ Corp

SEALSQ Corp, Company No 2095496 (the Company)

We are lawyers qualified to practise in the British Virgin Islands and have been asked to provide this legal opinion to you with regard to the laws of the British Virgin Islands in connection with the Company’s registration statement on Form F-3, including all amendments or supplements thereto, and accompanying prospectus filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the Registration Statement) relating to the offer and sale, from time to time, by the Company of certain of its ordinary shares with a par value of USD$0.01 per share (the Ordinary Shares), warrants to purchase Ordinary Shares (the Warrants), subscription rights (the Rights) and a combination of such securities, separately or as units in one or more offerings, as described in the Registration Statement (the Securities).

Where the context provides, capitalised terms defined in the Registration Statement shall have the same meanings when used in this opinion.

We are furnishing this opinion as Exhibit 5.1 and 23.1 to the Registration Statement.

As part of the corporate actions taken and to be taken in connection with the issuance and sale of the Securities (the corporate proceedings), the Company has informed us that before the Securities are issued and sold under the Registration Statement, the board of directors of the Company (Board) will authorise the issuance and approve the terms of any Securities to be issued and sold from time to time under the Registration Statement, and, in each case in a form acceptable to us and British Virgin Islands law, and such applicable corporate proceedings (hereinafter referred to as the Board Authorisations) shall be in full force and effect at the time of any such issuance and sale.

The Company has informed us that the Securities will be sold or delivered on a delayed or continuous basis from time to time as set forth in the Registration Statement (and any amendments and/or supplement thereto), the prospectus contained therein and any prospectus supplement. We understand that prior to the sale of any Securities under the Registration Statement, the Company will afford us an opportunity to review the applicable Board Authorisations and, if necessary, amendments to the Memorandum and Articles (as defined in Schedule 1) and operative documents pursuant to which such Securities are to be sold and will file any applicable amendment and/or supplement to the Registration Statement (which may include as an exhibit thereto an amended opinion) or prospectus supplement as we may reasonably consider necessary or appropriate by reason of the terms of the sale of such Securities.

Jersey legal services are provided through a referral arrangement with Harneys (Jersey) which is an independently owned and controlled Jersey law firm.

A list of partners is available for inspection at our offices.

In each case, except as otherwise set forth in any applicable amendment and/or supplement to the Statement or prospectus supplement:

(i)

any Ordinary Shares will be issued by the Company under and in accordance with the Memorandum and Articles, as amended from time to time;

(ii)

any Warrants will be issued pursuant to one or more warrant agreements (each, a Warrant Agreement) entered into between the Company and one or more warrant agents in a form filed as an exhibit to a prospectus supplement to the Statement or incorporated by reference therein, and one or more resolutions of the Board;

(iii)

any Rights will be issued pursuant to one or more rights agent agreements (each, a Rights Agreement) entered into between the Company and one or more rights agents in a form filed as an exhibit to a prospectus supplement to the Registration Statement or incorporated by reference therein, and one or more resolutions of the Board; and

(iv)

any Units will be issued pursuant to one or more unit agreements (each, a Unit Agreement) to be entered into by the Company and one or more unit agents in a form filed as an exhibit to a prospectus supplement to the Registration Statement or incorporated by reference therein, and one or more resolutions of the Board.

For the purposes of giving this opinion, we have examined the Documents (as defined in Schedule 1). We have not examined any other documents, official or corporate records or external or internal registers and have not undertaken or been instructed to undertake any further enquiry or due diligence in relation to the transaction which is the subject of this opinion.

In giving this opinion we have relied upon the assumptions set out in Schedule 2 which we have not verified.

Based solely upon the foregoing examinations and assumptions and having regard to legal considerations which we deem relevant, and subject to the qualifications set out in Schedule 3, we are of the opinion that under the laws of the British Virgin Islands:

Existence and Good Standing.

1.1

The Company is a company duly incorporated with limited liability and is validly existing and in good standing under the laws of the British Virgin Islands. The Company is a separate legal entity and is subject to suit in its own name.

Authorised Shares.

2.1

The Company is authorised to issue a maximum of 210,000,000 shares in two classes as follows:

(a)

200,000,000 Ordinary Shares with a par value of US$0.01; and

(b)

10,000,000 Class F Shares with a par value of US$0.05 (Class F Shares).

Issued Shares.

3.1

As of the date of the Director’s Certificate (as defined in Schedule 1) the Company has:

(a)

104,508,901 Ordinary Shares, issued and outstanding;

(b)

1,499,800 Class F Shares, issued and outstanding.

Capacity and Power.

4.1

The execution and delivery of the Registration Statement by the Company and the performance of its obligations thereunder is within the corporate capacity and power of the Company and has been duly authorised and approved by all necessary corporate action of the Company.

Valid Issuance of Ordinary Shares.

5.1

The allotment and issue of Ordinary Shares as contemplated by the Registration Statement has been duly authorised and, when allotted, issued and fully paid for in accordance with the Registration Statement, and when the names of the shareholders are entered in the register of members of the Company, the Ordinary Shares will be validly issued, allotted, fully paid and non-assessable, and there will be no further obligation of the holders of any of the Ordinary Shares to make any further payment to the Company in respect of such Ordinary Shares.

Valid Issuance of Warrants, Rights, and Units.

6.1

When:

(a)

the applicable Warrants have been duly authorised by the Company;

(b)

the final terms of the Warrants have been duly established and approved by the appropriate Board Authorisations; and

(c)

the applicable Warrants have been duly executed by the Company and countersigned or authenticated in accordance with the applicable Warrant Agreement and delivered to and paid for by the purchasers thereof as contemplated by the Statement (including any amendments and/or supplement thereto) and any prospectus supplements relating thereto, and as contemplated by the applicable Board Authorisations or other corporate proceedings, such Warrants will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms.

6.2

When:

(a)

the applicable Rights have been duly authorised by the Company;

(b)

the final terms of the Rights have been duly established and approved by the appropriate Board Authorisations; and

(c)

the applicable Rights have been duly executed by the Company and countersigned or authenticated in accordance with the applicable Rights Agreement and delivered to and paid for by the purchasers thereof as contemplated by the Statement (including any amendments and/or supplement thereto) and any prospectus supplements relating thereto, and as contemplated by the applicable Board Authorisations or other corporate proceedings, such Rights will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms.

6.3

When:

(a)

the applicable Units have been duly authorised by the Company;

(b)

the final terms of the Units have been duly established and approved; and

(c)

the applicable Units have been duly executed by the Company and countersigned or authenticated in accordance with the applicable Unit Agreement and delivered to and paid for by the purchasers thereof as contemplated by the Statement (including any amendments and/or supplement thereto) and any prospectus supplements relating thereto, and as contemplated by the applicable Board Authorisations or other corporate proceedings, such Units will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms.

Searches.

7.1

No court proceedings pending against the Company are indicated from our searches at the British Virgin Islands High Court Registry referred to in paragraph 3 of Schedule 1.

7.2

Based on our searches at the British Virgin Islands Registry of Corporate Affairs and the British Virgin Islands High Court Registry referred to in paragraphs 2 and 5 of Schedule 1, no currently valid order or resolution for liquidation of the Company and no current notice of appointment of a receiver over the Company or any of its assets appears on the records maintained in respect of the Company.

This opinion is confined to the matters expressly opined on herein and given on the basis of the laws of the British Virgin Islands as they are in force and applied by the British Virgin Islands courts at the date of this opinion. We have made no investigation of, and express no opinion on, the laws of any other jurisdiction. We express no opinion as to matters of fact. Except as specifically stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in the Statement. We express no opinion with respect to the commercial terms of the transactions the subject of this opinion.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our name under the heading “Legal Matters” and elsewhere in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act, as amended, or the Rules and Regulations of the Commission thereunder.

Yours faithfully

Harney Westwood & Riegels (BVI) LP

Schedule 1

List of Documents and Records Examined

A copy of the Company’s certificate of incorporation obtained from the Registry of Corporate Affairs on 4 August 2023 and the memorandum and articles of association of the Company dated 15 March 2023, as amended on 21 December 2023, (Memorandum and Articles) which our searches dated 28 February 2025 indicated have not been subsequently amended.

The records and information certified by Harneys Corporate Services Limited, the registered agent of the Company, on 28 February 2025 of the statutory documents and records maintained by the Company at its registered office (the Registered Agent’s Certificate).

The public records of the Company on file and available for inspection at the Registry of Corporate Affairs, Road Town, Tortola, British Virgin Islands on 28 February 2025.

A certificate of good standing issued by the Registrar of Corporate Affairs with respect to the Company dated 14 January 2025 (which expires on 2 July 2025).

The records of proceedings on file with, and available for inspection on 28 February 2025 at the High Court of Justice, British Virgin Islands.

A certificate from a director of the Company, dated 27 February 2025 (Director’s Certificate).

A copy of the resolutions of the board of directors of the Company dated 28 February 2025 approving the issue of the Ordinary Shares (the Resolutions).

(1 to 7 above are the Corporate Documents).

The Registration Statement.

The Corporate Documents and the Registration Statement are collectively referred to in this opinion as the Documents.

Schedule 2

Assumptions

Directors. The board of directors of the Company considers the filing of the Registration Statement and the transactions contemplated thereby to be in the best interests of the Company and no director has a financial interest in or other relationship to a party or the transactions contemplated by the Statement which has not been properly disclosed in the Resolutions.

Solvency. The Company was on the date of this opinion able to pay its debts as they became due, and issuing the securities as contemplated by the Registration Statement will not cause the Company to become unable to pay its debts as they fall due.

Authenticity of Documents. All original Documents are authentic, all signatures, initials and seals are genuine, all copies of Documents are true and correct copies and the Registration Statement conforms in every material respect to the latest draft of the same produced to us and, where the Registration Statement has been provided to us in successive drafts marked-up to indicate changes to such documents, all such changes have been so indicated.

Corporate Documents. All matters required by law to be recorded in the Corporate Documents are so recorded, all corporate minutes, resolutions, certificates, documents and records which we have reviewed are accurate and complete, and all facts expressed in or implied thereby are accurate and complete. The information recorded in the Registered Agent’s Certificate was accurate as at the date of the passing of the Resolutions.

Resolutions. The written Resolutions have been duly executed (and where executed by a corporate entity, such execution has been duly authorised if so required) by or on behalf of each director or shareholder (as the case may be), and the signatures and initials thereon are those of a person or persons in whose name the Resolutions have been expressed to be signed. The Resolutions remain in full force and effect.

Unseen Documents. Save for the Documents provided to us there are no resolutions, agreements, documents or arrangements which materially affect, amend or vary the transactions envisaged in the Documents.

Director’s Certificate. The contents of the Director’s Certificate are true and accurate as at the date of this opinion and there is no information not contained in the Director’s Certificate that will in any way affect this opinion.

Schedule 3

Qualifications

Enforceability. The term enforceable as used above means that the obligations assumed by the Company under the relevant instrument are of a type which the courts of the British Virgin Islands enforce. It does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular:

(a)

Insolvency. Rights and obligations may be limited by bankruptcy, insolvency, liquidation, winding-up, reorganisation, moratorium, readjustment of debts, arrangements and other similar laws of general application affecting the rights of creditors.

(b)

Limitation Periods. Claims under the Statement may become barred under the Limitation Act 1961 relating to the limitation of actions in the British Virgin Islands or may be or become subject to defences of set-off, estoppel or counterclaim.

(c)

Equitable Rights and Remedies. Equitable rights may be defeated by a bona fide purchaser for value without notice. Equitable remedies such as injunctions and orders for specific performance are discretionary and will not normally be available where damages are considered an adequate remedy.

(d)

Fair Dealing. Strict legal rights may be qualified by doctrines of good faith and fair dealing - for example a certificate or calculation as to any matter might be held by a British Virgin Islands court not to be conclusive if it could be shown to have an unreasonable or arbitrary basis, or in the event of manifest error.

(e)

Prevention of Enforcement. Enforcement may be prevented by reason of fraud, coercion, duress, undue influence, unreasonable restraint of trade, misrepresentation, public policy or mistake or limited by the doctrine of frustration of contracts.

(f)

Penal Provisions. Provisions, for example, for the payment of additional interest in certain circumstances, may be unenforceable to the extent a court of the British Virgin Islands determines such provisions to be penal.

(g)

Currency. A British Virgin Islands court retains a discretion to denominate any judgment in US dollars.

(h)

Confidentiality. Provisions imposing confidentiality obligations may be overridden by the requirements of legal process.

(i)

Award of Costs. In principle the courts of the British Virgin Islands will award costs and disbursements in litigation in accordance with the relevant contractual provisions but there remains some uncertainty as to the way in which the rules of the High Court will be applied in practice.

(j)

Inappropriate Forum. The courts of the British Virgin Islands may decline to exercise jurisdiction in relation to substantive proceedings brought under or in relation to the Statement in matters where they determine that:

(i)

such proceedings may be tried in a more appropriate forum;

(ii)

proceedings are already underway in a different forum; or

(iii)

the issues have already been finally determined by another forum.

(k)

Financial Services Business. An agreement made by a person in the course of carrying on unlicensed financial services business is unenforceable against the other party to the agreement under section 50F of the Financial Services Commission Act 2001.

Public Records. Records reviewed by us may not be complete for various reasons. In particular you should note that:

(a)

in special circumstances the court may order the sealing of the court record, which would mean that a record of the court action would not appear on the High Court register;

(b)

failure to file notice of appointment of a receiver with the Registry of Corporate Affairs does not invalidate the receivership but merely gives rise to penalties on the part of the receiver;

(c)

a liquidator of a British Virgin Islands company has 14 days after their appointment within which they must file notice of their appointment at the Registry of Corporate Affairs; and

(d)

although amendments to the Memorandum and Articles of Association of a company are normally effective from the date of registration with the Registry of Corporate Affairs, it is possible for a British Virgin Islands court to order that they be treated as being effective from an earlier date, and searches would not reveal the amendments until the court order was subsequently filed,

and accordingly our searches would not indicate such issues.

Foreign Statutes. We express no opinion in relation to provisions making reference to foreign statutes in the Statement.

Good Standing. To maintain the Company in good standing under the laws of the British Virgin Islands, annual licence fees must be paid to the Registrar of Corporate Affairs.

Statutory Powers. Provisions in the Statement which fetter any statutory power of the Company may not be enforceable.

Conflict of Laws. An expression of an opinion on a matter of British Virgin Islands law in relation to a particular issue in this opinion should not necessarily be construed to imply that the British Virgin Islands courts would treat British Virgin Islands law as the proper law to determine that issue under its conflict of laws rules.

Sanctions. The obligations of the Company may be subject to restrictions pursuant to United Nations and United Kingdom sanctions as implemented under the laws of the British Virgin Islands.

Economic Substance. We have undertaken no enquiry and express no view as to the compliance of the Company with the Economic Substance (Companies and Limited Partnerships) Act 2018.
