Pursuant to this prospectus supplement and the accompanying prospectus, we are offering in a registered direct offering to certain institutional investors, 4,545,456 ordinary shares of a par value of US$0.0001 each (the “Ordinary Shares”), and warrants to purchase up to 4,545,456 Ordinary Shares (the “Purchase Warrants”). Each Ordinary Share is being sold together with one Purchase Warrant. The offering price per Ordinary Share and accompanying Purchase Warrant is $11.00. We are also offering the Ordinary Shares that are issuable from time to time upon exercise of the Purchase Warrants.

The Purchase Warrants will have an exercise price per share of $13.20 and will be exercisable beginning on the date of issuance until the five-year anniversary of the date of issuance.

Our Ordinary Shares is currently listed on the Nasdaq Capital Market under the symbol “TOYO.” On June 23, 2026, the last reported sale price of our Ordinary Shares on the Nasdaq Capital Market was $12.93 per share. Certain of our warrants outstanding prior to this offering is trading on the OTC Markets under the trading symbol “TOYWF.” On June 23, 2026, the closing price for our warrants on OTC Markets was $2.80. However, there is no established public trading market for the Purchase Warrants, and we do not expect a market to develop. In addition, we do not intend to list the Purchase Warrants on the Nasdaq Capital Market, any other national securities exchange or any other nationally recognized trading system.

This summary does not contain all of the information you should consider before making an investment decision.

Company Overview

Our mission is to power the world with green and clean energy.

We are an early-stage company incorporated in November 2022 to separate the solar cell and module production businesses from VSUN, a majority-owned subsidiary of Fuji Solar and our affiliate. We are committed to becoming a reliable integrated service solar solutions provider in the United States and globally, integrating the upstream production of wafer and silicon, midstream production of solar cell, downstream production of photovoltaic (PV) modules, and potentially other stages of the solar power supply chain.

We are headquartered in Japan. Currently, we have established two solar cell plants located in Vietnam and Ethiopia. To date, our cell plant in Vietnam has commenced commercial production since the second half of 2023 and achieved its full 2GW annual capacity. By locating our solar cell production in Vietnam, Southeast Asia and incorporating automatic guided vehicles (AGVs) and TOPCon technology in our cell plant, we are well positioned to produce high quality solar cells at a competitive scale and cost. We may plan to further expand the capacity of our facility in Vietnam, and the management is actively observing and analyzing the recent changes and development in relevant regulations and government policies and environmental conditions and evaluating the construction plan and expects to commence the construction when there is more clarity in the relevant regulations and government policies. We have strategically selected a solar cell plant located in Hawassa, Ethiopia, taking advantage of the country’s favorable investment policies, tariff status and ample hydropower supply. Our solar cell plant in Ethiopia has commence production in April 2025 with 2GW production capacity and expanded the capacity to 4GW in August 2025. We aim to fully utilize our annual solar cell production capacity from Vietnam and Ethiopia, as well as collaborations with some OEMs to fulfill additional orders, and supply our solar cells under the “TOYO Solar” brand to our affiliate VSUN and a select group of PV module manufacturers. As of December 31, 2025, we had entered into supply agreements with over 50 third-party solar cell customers and are in active negotiation with several potential customers to supply our solar cells.

We are preparing ourselves for the manufacturing of solar PV modules for sales in the United States, allowing our affiliate VSUN to focus on ex-U.S. PV module markets. Specifically, we have leased a facility located in Texas to accommodate our solar module production. We completed the construction for the first 1GW capacity and commenced production in October 2025. We plan to supply our solar PV modules, initially in collaboration with VSUN, leveraging its experience and certification. Later, we will independently manufacture and supply PV modules under the VSUN brand acquired by us in September 2025. Our module facility in the Houston metropolitan area commenced commercial operations in October 2025. We also plan to continue our collaboration with VSUN to support our PV module supply under VSUN brand based on market demands and our business development. We plan to construct a 1.5 GW heterojunction (HJT) solar cell plant at our existing solar module site in Texas, and continue to be dedicated to becoming a reliable integrated service solar solutions provider in the United States and globally.

S-1

VSUN, our affiliate, is a specialized PV modules producer with an established presence and brand recognition in regions including the United States, Europe and Asia. Since the third quarter of 2019, VSUN has been listed by Bloomberg New Energy Finance (NEF) as one of Tier 1 PV module manufacturers. VSUN’s solar modules are recognized as the core assets of efficient and reliable PV power stations, which would be beneficial for solar market players who utilize VSUN’s solar modules to obtain financing from such banks and financial institutions. In September 2025, TOYO acquired the VSUN brand from VSUN. The acquisition supports TOYO’s strategic expansion into the U.S market, complementing its existing manufacturing footprint for solar cells in Vietnam and Ethiopia. We believe that by leveraging VSUN’s successful experience and market insights, as well as its strong presence and reputation in the solar industry, we will be able to quickly obtain access to the U.S. market with minimal upfront marketing and brand promotion, and establish ourselves as a trusted PV module supplier in the United States and even globally.

We believe our Japanese-style corporate culture will enable us to strive for and sustain operational excellence. This Japanese-style corporate culture values discipline and a down-to-earth attitude, aligns corporate growth and personal career goals, and encourages employees to be self-driven. Further, we intend to implement the Japanese-style management system which is centered around the manufacturing sites and intended to resolve issues arising from the sites in the most efficient and effective manner. We believe our corporate culture and management style could enable us to quickly grow as an independent entity and achieve our operational objectives.

We are the first Japanese solar cell company listed in the United States, uniquely positioned to combine the U.S. capital markets, Japanese products, brands and management team, as well as Southeast Asia’s manufacturing resources, to enhance its competitiveness in the solar industry and become a reliable supplier of quality solar cells and PV modules to the global solar energy community.

Implications of Being an Emerging Growth Company, a Foreign Private Issuer and a Controlled Company

Emerging Growth Company

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and we may take advantage of reduced reporting requirements that are otherwise applicable to public companies. Section 107 of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with those standards. The JOBS Act also exempts us from having to provide an auditor attestation of internal control over financial reporting under Sarbanes-Oxley Act Section 404(b).

We will remain an emerging growth company until the earlier of: (i) the last day of the fiscal year (a) following the fifth anniversary of the July 1, 2024, (b) in which we have an annual total gross revenue of at least US$1.235 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our ordinary equity that is held by non-affiliates exceeds US$700 million as of the last business day of the second fiscal quarter of such fiscal year; and (ii) the date on which we have issued more than US$1 billion in non-convertible debt securities during the prior three-year period. References herein to “emerging growth company” have the meaning associated with it in the JOBS Act.

Foreign Private Issuer

As a “foreign private issuer,” we are subject to different U.S. securities laws than domestic U.S. issuers. The rules governing the information that we must disclose differ from those governing U.S. companies pursuant to the Exchange Act. We will be exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements to shareholders. Those proxy statements are not expected to conform to Schedule 14A of the proxy rules promulgated under the Exchange Act.

S-2

In addition, as a “foreign private issuer,” our officers and directors and holders of more than 10% of the issued and outstanding Ordinary Shares, will be exempt from the rules under the Exchange Act requiring insiders to report purchases and sales of Ordinary Shares as well as from Section 16 short swing profit reporting and liability. We may take advantage of these exemptions until such time as we are no longer a foreign private issuer. We would cease to be a foreign private issuer at such time as more than 50% of our outstanding voting securities are held by U.S. residents and any of the following three circumstances applies: (i) the majority of our executive officers or directors are U.S. citizens or residents, (ii) more than 50% of our assets are located in the United States or (iii) our business is administered principally in the United States. See “Risk Factors — Risks Related to Our Securities — As we are a “foreign private issuer” and intend to follow certain home country corporate governance practices, our shareholders may not have the same protections afforded to shareholders of companies that are subject to all Nasdaq corporate governance requirements” starting on page 26 of our most recent annual report on Form 20-F.

Controlled Company

As of the date hereof, Mr. Junsei Ryu, our former chief executive officer and chairman of the board of directors, controls approximately 66.87% of the aggregated voting power of the Company’s total issued and outstanding share capital, without taking into account of potential source of dilution. As a result, we are a “controlled company” within the meaning of applicable Nasdaq listing rules. Under these rules, a company of which more than 50% of the voting power for the election of directors is held by an individual, group or another company is a “controlled company.” For so long as we remain a “controlled company,” we may elect not to comply with certain corporate governance requirements, including the requirements:

●

that a majority of the board of directors consists of independent directors;

●

for an annual performance evaluation of the nominating and corporate governance and compensation committees;

●

that we have a nominating and corporate governance committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and

●

that we have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibility.

We intend to use these exemptions and may continue to use all or some of these exemptions in the future. As a result, you may not have the same protections afforded to shareholders of companies that are subject to all of the Nasdaq corporate governance requirements.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully review the risks and uncertainties described below and under the section titled “Risk Factors” in our Annual Report on Form 20-F for the year ended December 31, 2025, filed with the Securities and Exchange Commission on April 1, 2026 (the “Annual Report”) that is incorporated by reference into this prospectus supplement, together with other information in this prospectus supplement and the accompanying prospectus and the information and documents incorporated by reference therein before you make a decision to invest in our securities. Each of the risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations. Please also read carefully “Note Regarding Forward-Looking Statements” in this prospectus supplement.

Risks Related to this Offering

If you purchase Ordinary Shares sold in this offering, you will experience immediate and substantial dilution in the net tangible book value of your shares. In addition, we may issue additional equity or convertible debt securities in the future, which may result in additional dilution to investors.

The offering price per Ordinary Share in this offering exceeds the net tangible book value per share of our outstanding Ordinary Shares. As a result, investors purchasing Ordinary Shares in this offering may experience immediate and substantial dilution in the net tangible book value of the shares they purchase. For a more detailed discussion of the foregoing, see the section entitled “Dilution” below. To the extent outstanding stock options or warrants are exercised, there will be further dilution to new investors. In addition, to the extent we need to raise additional capital in the future and we issue additional equity or convertible debt securities, our then existing stockholders may experience dilution and the new securities may have rights senior to those of the securities offered in this offering.

Our management team may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a significant return.

Our management will have broad discretion over the use of proceeds from this offering. We intend to use the net proceeds from this offering, together with our existing cash and cash equivalents and short-term investments, for the construction of previously announced 1.5 GW heterojunction (HJT) solar cell manufacturing facility in the Houston metropolitan area, Texas, and other general corporate and working capital purposes. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be used for corporate purposes that do not increase our operating results or enhance the value of our Ordinary Shares.

We do not intend to apply for any listing of the Purchase Warrants on any exchange or nationally recognized trading system, and we do not expect a market to develop for the Purchase Warrants.

We do not intend to apply for any listing of Purchase Warrants on the Nasdaq Capital Market or any other securities exchange or nationally recognized trading system, and we do not expect a market to develop for the Purchase Warrants. Without an active market, the liquidity of the Purchase Warrants will be limited. Further, the existence of the Purchase Warrants may act to reduce both the trading volume and the trading price of our Ordinary Shares.

S-5

The Purchase Warrants purchased in this offering are speculative in nature and do not entitle the holder to any rights as shareholders until the holder exercises the warrant for Ordinary Shares, except as set forth in the Purchase Warrants.

Until you acquire Ordinary Shares upon exercise of your Purchase Warrants purchased in this offering, such warrants will not provide you any rights as a shareholder, such as voting rights, except as set forth therein. Upon exercise of your Purchase Warrants purchased in this offering, you will be entitled to exercise the rights of a shareholder only as to matters for which the record date occurs on or after the exercise date. Moreover, following this offering, the market value of the Purchase Warrants is uncertain and there can be no assurance that the market value of the Purchase Warrants will equal or exceed their offering price.

We may not receive any additional funds upon the exercise of the Purchase Warrants.

Each Purchase Warrant may be exercised by way of a cashless exercise if permitted by the terms of such warrants, meaning that the holder may not pay a cash purchase price upon exercise, but instead would receive upon such exercise the net number of Ordinary Shares determined according to the formula set forth in the Purchase Warrant. Accordingly, we may not receive any additional funds upon the exercise of the Purchase Warrants.

Risks Related to TOYO’s Business and Industry

We may face risks associated with the current and future manufacturing, marketing, distribution and sale of our products internationally and the construction and operation of our overseas manufacturing facilities. If we are unable to effectively manage these risks, our business and operations abroad may be adversely affected and our ability to maintain, develop and expand our business abroad may be restricted.

While we are headquartered in Japan, we have constructed a solar cell plant in Vietnam and established a new solar cell plant in Ethiopia and a solar module plant in Texas, U.S. We are also analyzing and evaluating the timing and venues to further expand to build our solar cell plants. The current and future manufacturing, marketing, distribution and sale of our products internationally, as well as the construction and operation of our manufacturing facilities internationally may expose us to a number of risks, including those associated with:

●

fluctuations in currency exchange rates;

●

costs associated with understanding local markets and trends;

●

costs associated with establishment of overseas manufacturing facilities;

●

marketing and distribution costs;

●

customer services and support costs;

●

risk management and internal control structures for our overseas operations;

●

compliance with the different commercial, operational, environmental and legal requirements;

●

obtaining or maintaining certifications for production, marketing, distribution and sales of our products or, if applicable, services;

●

maintaining our reputation as an environmentally friendly enterprise for our products or services;

●

obtaining, maintaining or enforcing intellectual property rights;

●

changes in prevailing economic conditions and regulatory requirements;

●

transportation and freight costs;

●

employing and retaining manufacturing, technology, sales and other personnel who are knowledgeable about, and can function effectively in, overseas markets;

S-6

●

trade barriers such as trade remedies, which could increase the prices of the raw materials for our solar products, and export requirements, tariffs, taxes and other restrictions and expenses, which could increase the prices of our products and make us less competitive in some countries;

●

challenges due to our unfamiliarity with local laws, regulation and policies, our absence of significant operating experience in local market, increased cost associated with establishment of overseas operations and maintaining a multinational organizational structure; and

●

other various risks that are beyond our control.

Our manufacturing capacity in Vietnam, Ethiopia and Texas, U.S. requires us to comply with different laws and regulations, including national and local regulations relating to production, environmental protection, employment and the other related matters. Our failure to obtain the required approvals, permits, licenses, filings or to comply with the conditions associated therewith could result in fines, sanctions, suspension, revocation or non-renewal of approvals, permits or licenses, or even criminal penalties, which could have a material adverse effect on our business, financial condition and results of operations.

For example, the U.S. government has begun enforcing a long-existing ban on U.S. importation of products produced with forced labor in ways that may adversely affect our business. Section 307 of the U.S. Tariff Act of 1930, as amended, (“Section 307”), prohibits U.S. importation of goods that are produced or manufactured, wholly or in part, in any non-U.S. country by forced or indentured labor. On June 24, 2021, U.S. Customs and Border Protection (“CBP”) issued a Withhold Release Order against Hoshine Silicon Industry Co. Ltd. (“Hoshine WRO”). As a result, personnel at all U.S. ports of entry have been instructed to immediately begin detaining shipments that contain silica-based products made by Hoshine or materials and goods derived from or produced using those silica-based products.

On December 23, 2021, President Biden signed the Uyghur Forced Labor Prevention Act (the “UFLPA”) into law. The UFLPA aims to strengthen the existing laws on forced labor by prohibiting the importation and entry of any goods made with forced labor in the Xinjiang Uyghur Autonomous Region (“XUAR”) of the PRC, and establishes several enforcement mechanisms and procedures to do so. Since June 21, 2022, CBP has begun applying the “Rebuttal Presumption” established in Section 3 of UFLPA and prohibits any “goods, wares, articles, or merchandise mined, produced, or manufactured wholly or in part in the XUAR” or produced by an entity on the list to be issued pursuant to the UFLPA, unless CBP determines that importer of record has (i) fully complied with the supply chain guidance described in Section 2 of the UFLPA and any accompanying regulations, and (ii) completely and substantively responded to inquiries for information by CBP. Pursuant to UFLPA, the U.S. government issued a list of entities involved in and products produced from forced labor, “guidance to importers” with respect to forced labor due diligence as well as a strategy report to prevent importation of goods produced with forced labor. Since the UFLPA took effect on June 12, 2022, CBP has been actively reviewing and detaining shipments of solar panels and solar cells to the United States. Recently, we have observed that the CBP has increased its scrutiny and enforcement efforts under the UFLPA, and certain of our shipments of solar cells and modules have been detained by CBP for UFLPA related review. We have engaged outside counsel specialized in CBP enforcement to fully cooperate with the CBP to promptly provide requested information. Although, as of the date hereof, such detentions have not, and may not in the future, cause material interruption to our operation and we believe that we will be able to provide full and transparent information to demonstrate our compliance, there can be no assurance whether and when CBP will be satisfied with our responses and release the detained shipments, and if any additional shipments may be subject to further review or detention.

In addition to the actions taken or being considered by the U.S. government as discussed above, there is a growing concern regarding the alleged use of forced labor issue in the XUAR in the European Union, Australia, Japan and certain other countries. For example, in June 2022, the European Parliament passed Resolution on the human rights situation in the XUAR, including the Xinjiang police files. European Commission issued, on September 14, 2022, a Proposal for a Regulation of the European Parliament and of the Council on prohibiting products made with forced labor on the European Union. If any new legislation or regulatory action with respect to these issues were to be enacted in those regions that impose additional restrictions or requirements on importation of goods that are produced or manufactured, wholly or in part, in the XUAR, our business and operation in these regions would be adversely affected.

S-7

Except as disclosed above, although such policies have impacted the operations of some participants in the solar industry, our operations have not yet been adversely affected by Hoshine WRO or UFLPA or other regulations or government initiatives discussed above.

On April 24, 2024, the American Alliance for Solar Manufacturing Trade Committee (the “Committee”) filed AD and CVD petitions on imports of crystalline silicon photovoltaic (“CSPV”) cells from Cambodia, Malaysia, Thailand, and Vietnam. The AD petition alleges that imports of CSPV cells from the targeted countries are being sold in the United States at less than fair value. The CVD petition alleges that the governments of the targeted countries are providing countervailable subsidies with respect to the manufacture, production, and export of CSPV cells. The Commerce Department will determine whether imports of CSPV cells from the targeted countries were dumped in the United States, and establish the ADs that will be imposed. It will also determine whether the governments of the targeted countries subsidized exports of CSPV cells to the United States. The International Trade Commission (“ITC”) will determine whether imports of the subject merchandise are materially injuring, or threaten to materially injure, the domestic industry. In April 2025, the Commerce Department announced its final affirmative AD/CVD determinations and, among the others, assigned a final AD rate of 271.28% and a final CVD rate of 124.57% for solar cells and modules from Vietnam involved in circumvention of U.S. duties, and further, among the others, assigned a different AD rate of 77.12% to our affiliate VSUN.

Recently, the U.S. government and President Trump have made public statements and taken certain actions indicating significant changes in U.S. trade policy, including imposing new or increased tariffs on certain goods imported into the United States. We currently have three plants located in Vietnam, Ethiopia and Texas, U.S. U.S. will continue to be an important market for us. It is uncertain if there will be any changes to the imposed tariffs, with respect to the subject countries, products or rates, and how those tariffs would impact our operations. Furthermore, changes in U.S. trade policy could trigger retaliatory actions by affected countries, which could impose restrictions on our ability to purchase and import raw material or equipment from other countries to the U.S. to our solar module plant in Texas. As of the date hereof, we cannot predict what actions may ultimately be taken with respect to tariffs or trade relations between the United States and other countries, what products may be subject to such actions, or what actions may be taken by the other countries in retaliation. Any additional tariffs imposed on our products, raw material or equipment for our plants could have a material adverse effect on our business, results of operations and financial position.

However, there is no guarantee that our operations will not be materially adversely affected by laws and regulations in the United States or other jurisdictions in the future. As we enter into new markets in different jurisdictions, we will face different business environments and industry conditions, and we may spend substantial resources familiarizing ourselves with the new environment and conditions. To the extent that our business operations are affected by unexpected and adverse economic, regulatory, social and political conditions in the jurisdictions in which we have operations, we may experience project disruptions, loss of assets and personnel, and other indirect losses that could adversely affect our business, financial condition and results of operations. Any of these events may increase the related costs, or impair our ability to run our operations in the future on a cost effective basis, which could in turn have a material adverse effect on our business and results of operations.

Use of Proceeds

We estimate that the net proceeds to us from the sale of securities in this offering will be approximately $47.1 million, after deducting placement agent fees and estimated offering expenses payable by us, excluding the proceeds, if any, from the cash exercise of the Purchase Warrants issued in this offering.

We will only receive additional proceeds from the exercise of the Purchase Warrants if the Purchase Warrants are exercised and the holders of such Purchase Warrants pay the exercise price in cash upon such exercise and do not utilize the cashless exercise provision of the Purchase Warrants.

We intend to use the net proceeds from this offering, if any, to build our previously announced 1.5 GW heterojunction (HJT) solar cell manufacturing facility in the Houston metropolitan area, Texas, as well as for general corporate purposes.

The amounts and timing of our actual expenditures will depend on numerous factors, including our development and commercialization efforts with respect to our product candidates, as well as the amount of cash used in our operations. We therefore cannot estimate with certainty the amount of net proceeds to be used for the purposes described above. We may find it necessary or advisable to use the net proceeds for other purposes, and we will have broad discretion in the application of the net proceeds.

Description of Securities Offered

Ordinary Shares

The material terms and provisions of our Ordinary Shares and each other class of our securities which qualifies or limits our Ordinary Shares are described in the section entitled “Description of Share Capital” of the accompanying prospectus and the Description of Registered Securities included as Exhibit 2.5 to the Annual Report.

Purchase Warrants

The following summary of certain terms and provisions of the Purchase Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Purchase Warrants the form of which will be filed as an exhibit to our Current Report on Form 6-K. Prospective investors should carefully review the terms and provisions of the form of Purchase Warrant for a complete description of the terms and conditions of the Purchase Warrants.

Duration and Exercise Price. Each Purchase Warrant offered hereby has an initial exercise price per share equal to $13.20. The Purchase Warrants are immediately exercisable upon issuance and may be exercised at any time until the five year anniversary of the date of issuance. The exercise price and number of Ordinary Shares issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our Ordinary Shares and the exercise price.

Exercisability. The Purchase Warrants will be exercisable, at the option of the holder, in whole or in part by delivering to us a duly executed exercise notice and, at any time a registration statement registering the issuance of Ordinary Shares underlying the Purchase Warrants under the Securities Act is effective and available for the issuance of such shares, or an exemption from registration under the Securities Act is available for the issuance of such shares, by payment in full in immediately available funds for the number of Ordinary Shares purchased upon such exercise.

Cashless Exercise. If at the time of exercise there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Ordinary Shares underlying the Purchase Warrants, then the Purchase Warrants may also be exercised, in whole or in part, at such time by means of a cashless exercise, in which case the holder would receive upon such exercise the net number of Ordinary Shares determined according to the formula set forth in the warrant.

Exercise Limitation. A holder will not have the right to exercise any portion of the Purchase Warrants if the holder (together with its affiliates) would beneficially own in excess of 4.99% (or, upon election of the holder, 9.99%) of the number of our Ordinary Shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Purchase Warrants. However, any holder may increase or decrease such percentage, but in no event may such percentage be increased to more than 9.99%, provided that any increase will not be effective until the 61st day after such election.

Exercise Price Adjustment. The exercise price of the Purchase Warrants is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our Ordinary Shares.

Transferability. Subject to applicable laws, the Purchase Warrants may be offered for sale, sold, transferred or assigned without our consent.

S-10

Exchange Listing. There is no established trading market for the Purchase Warrants, and we do not expect a market to develop. In addition, we do not intend to apply for the listing of the Purchase Warrants on any national securities exchange or other trading market.

Fundamental Transactions. In the event of any fundamental transaction, as described in the Purchase Warrants and generally including any merger with or into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our Ordinary Shares, then upon any subsequent exercise of a Purchase Warrant, the holder will have the right to receive as alternative consideration, for each Ordinary Share that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of Ordinary Shares of the successor or acquiring corporation of our company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of Ordinary Shares for which the Purchase Warrant is exercisable immediately prior to such event.

Notwithstanding the foregoing, in the event of a fundamental transaction, we or a successor entity shall, at the holder’s option, exercisable at any time concurrently or within thirty (30) days following the consummation of a fundamental transaction, purchase the Purchase Warrant by paying to the holder an amount equal to the Black Scholes Value (as defined in each Purchase Warrant) of the remaining unexercised portion of the Purchase Warrant on the date of the fundamental transaction. If the fundamental transaction is not within our control, the holders of the Purchase Warrants will only be entitled to receive from us or a successor entity the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of the Purchase Warrant, that is being offered and paid to the holders of our Ordinary Shares in connection with the fundamental transaction, whether that consideration is in the form of cash, stock or any combination thereof, or whether the holders of our Ordinary Shares are given the choice to receive alternative forms of consideration in connection with the fundamental transaction.

Rights as a Stockholder. Except as otherwise provided in the Purchase Warrants or by virtue of such holder’s ownership of our Ordinary Shares, the holder of a Purchase Warrant will not have the rights or privileges of a holder of our Ordinary Shares, including any voting rights, until the holder exercises the warrant.

S-11

Dilution

If you invest in our securities in this offering, your interest will be diluted to the extent of the difference between the offering price per share and the net tangible book value per share of our Ordinary Shares after this offering, assuming no value is attributed to the Purchase Warrants issued in this offering.

Our net tangible book value as of December 31, 2025 was $111.1 million, or $2.94 per share. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of Ordinary Shares outstanding as of December 31, 2025. After giving effect to our sale in ATM of 413,784 Ordinary Shares at net proceeds of $5,546,293, our net tangible book value, as adjusted, as of December 31, 2025 was $116.6 million, or $3.06 per share. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by purchasers of Ordinary Shares in this offering and the net tangible book value per share, as adjusted, immediately after this offering.

After giving effect to our sale in this offering of 4,545,456 Ordinary Shares and Purchase Warrants at an offering price of $11.00 per Ordinary Share and accompanying Purchase Warrant, after deducting placement agent fees and estimated offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2025 would have been $163.7 million, or $3.83 per share. This represents an immediate increase of net tangible book value of $0.78 per share to our existing stockholders and an immediate dilution of $7.17 per share to new investors purchasing securities in this offering. The following table illustrates this per share dilution.

Offering price per share	$	11.00
Net tangible book value per share as of December 31, 2025, as adjusted	$	3.06
Increase in net tangible book value per share attributable to new investors	$	0.78
As adjusted net tangible book value per share after giving effect to this offering	$	3.83
Dilution per share to new investors participating in this offering	$	7.17

To the extent that any outstanding warrants or options are exercised or settled, new options are issued, or we issue additional Ordinary Shares or other equity or convertible debt securities in the future, there will be further dilution to investors participating in this Offering.

The above discussion and table are based on 38,173,492 Ordinary Shares issued and outstanding as of the date hereof, excluding (i) 2,832,990 Ordinary Shares reserved for future issuance under the Company’s 2024 Share Incentive Plan (the “2024 Plan”), and (ii) up to 4,969,296 Ordinary Shares issuable upon the exercise of our warrants outstanding as of the date hereof.

Plan of Distribution

We engaged the Placement Agents to act as our exclusive co-placement agents in connection with this offering pursuant to this prospectus supplement and accompanying prospectus. The Placement Agents are not purchasing or selling any securities offered by us in this offering, nor are they required to arrange for the purchase and sale of any specific number or dollar amount of such securities, other than to use their “reasonable best efforts” to arrange for the sale of such securities by us. Therefore, we may not sell all of securities being offered. The terms of this offering were subject to market conditions and negotiations between us, the Placement Agents and prospective investors. Our engagement agreement with the Placement Agents does not give rise to any commitment by the Placement Agents to purchase any of the securities, and the Placement Agents will have no authority to bind us by virtue of our engagement agreement with them. We have entered into securities purchase agreements directly with certain institutional investors who have agreed to purchase securities in this offering. We will only sell securities in this offering to investors who have entered into securities purchase agreements.

Delivery of the securities offered hereby is expected to take place on or about June 25, 2026, subject to satisfaction of certain closing conditions.

We have agreed to pay the Placement Agents collectively (i) a cash fee equal to 5.50% of the aggregate gross proceeds of this offering, (ii) up to $50,000 for fees and expenses of legal counsel and other out-of-pocket expenses, and (iii) clearing fees of $15,950.

We have also agreed to pay the Placement Agents a tail fee equal to the cash compensation in this offering for any financing or capital provided to us or subsidiaries by investors (i) that were introduced to us by the Placement Agents or with whom the Placement Agents had substantive communication on behalf of us “wall-crossed” by the Placement Agents during our engagement of the Placement Agents and (ii) who have expressed a bona fide interest in a potential investment during our engagement of the Placement Agents, and such offering is consummated or an agreement for sale of securities is entered into within the six (6) month period following either the expiration or the termination of our engagement of the Placement Agents, subject to certain exceptions.

We estimate the total expenses of this offering paid or payable by us, excluding the placement agent fees and expenses, will be approximately $145,950. After deducting the fees due to the Placement Agents and our estimated expenses in connection with this offering, we expect the net proceeds from this offering will be approximately $47.1 million.

Lock-Up Agreements

Our officers and directors and Mr. Junsei Ryu, as our controlling shareholder, will enter into lock-up agreements to agree, subject to specified exceptions, not to offer, sell, contract to sell, hypothecate, pledge or otherwise dispose of any Ordinary Shares or securities convertible into, or exchangeable or exercisable for, our Ordinary Shares for 90 days following the closing of this offering.

Subsequent Equity Sales

We have also agreed under the terms of the securities purchase agreements, until 90 days after the closing of this offering, not to (i) issue or sell any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional Ordinary Shares either (A) at a conversion price, exercise price or exchange rate or other price that is based upon and/or varies with the trading prices of or quotations for the Ordinary Shares at any time after the initial issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Ordinary Shares or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit or an “at-the-market” facility, subject to certain exceptions (including our ability to use our “at-the-market” facility with the Placement Agents).

S-13

Pricing of this Offering

The offering price was determined by negotiations between us and the purchasers. Among the factors considered in determining the offering price were our future prospects and those of our industry in general, earnings and certain other financial and operating information in recent periods, and the market prices of securities, and certain financial and operating information of companies engaged in activities similar to ours.

Indemnification

We have agreed to indemnify the Placement Agents against certain liabilities, including liabilities under the Securities Act and liabilities arising from breaches of representations and warranties contained in our engagement agreement with the Placement Agents. We have also agreed to contribute to payments the Placement Agents may be required to make in respect of such liabilities.

Other Relationships

From time to time, the Placement Agents may provide in the future various advisory, investment and commercial banking and other services to us in the ordinary course of business, for which they have received and may continue to receive customary fees and commissions. However, except as disclosed in this prospectus supplement, we have no present arrangements with the Placement Agents for any further services.

The Placement Agents have been acting as our sales agents in connection with our “at-the-market offering” pursuant to a Sales Agreement dated April 22, 2026, for which they have received compensation.

Regulation M Compliance

The Placement Agents may be deemed to be underwriters within the meaning of Section 2(a)(11) of the Securities Act, and any commissions received by them and any profit realized on the sale of our Ordinary Shares offered hereby by them while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. The Placement Agents will be required to comply with the requirements of the Securities Act and the Exchange Act, including, without limitation, Rule 10b-5 and Regulation M under the Exchange Act. These rules and regulations may limit the timing of purchases and sales of our securities by the placement agents. Under these rules and regulations, the Placement Agents may not (i) engage in any stabilization activity in connection with our securities; and (ii) bid for or purchase any of our securities or attempt to induce any person to purchase any of our securities, other than as permitted under the Exchange Act, until they have completed their participation in the distribution.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, or the SEC, under the Securities Act of 1933, as amended, or the Securities Act, using a “shelf” registration process. Under this shelf registration process, we may from time to time sell Ordinary Shares, warrants to purchase Ordinary Shares, debt securities or any combination of the foregoing, either individually or as units comprised of one or more of the other securities, in one or more offerings up to a total dollar amount of $200,000,000. We have provided to you in this prospectus a general description of the securities we may offer.

Company Overview

Our mission is to power the world with green and clean energy.

We are an early-stage company incorporated in November 2022 to separate the solar cell and module production businesses from Vietnam Sunergy Joint Stock Company, a Vietnam joint stock company (“VSUN”), a majority-owned subsidiary of Fuji Solar Co., Ltd, a Japanese company (“Fuji Solar”) and our affiliate. We are committed to becoming a reliable integrated service solar solutions provider in the United States and globally, integrating the upstream production of wafer and silicon, midstream production of solar cell, downstream production of photovoltaic (PV) modules, and potentially other stages of the solar power supply chain.

We are headquartered in Japan. Currently, we have established two solar cell plants located in Vietnam and Ethiopia. To date, our cell plant in Vietnam has commenced commercial production since the second half of 2023 and achieved its full 2GW annual capacity. By locating our solar cell production in Vietnam, Southeast Asia and incorporating automatic guided vehicles (AGVs) and TOPCon technology in our cell plant, we are well positioned to produce high quality solar cells at a competitive scale and cost. We may plan to further expand the capacity of our facility in Vietnam, and the management is actively observing and analyzing the recent changes and development in relevant regulations and government policies and environmental conditions and evaluating the construction plan and expects to commence the construction when there is more clarity in the relevant regulations and government policies. We have strategically selected a solar cell plant located in Hawassa, Ethiopia, taking advantage of the country’s favorable investment policies, tariff status and ample hydropower supply. Our solar cell plant in Ethiopia has commence production since April 2025 with 2GW production capacity. We commenced production of an additional 2 GW of solar cells at our Ethiopian facility and expect to reach full capacity in October 2025. As of the date hereto, we have received confirmed orders covering the 4 GW production capacity for our Ethiopian facility through the first half year of 2026. . We aim to fully utilize our annual solar cell production capacity from Vietnam and Ethiopia, as well as collaborations with some OEMs to fulfill additional orders, and supply our solar cells under the “TOYO Solar” brand to our affiliate VSUN and a select group of PV module manufacturers. For the six months ended June 30, 2025, we had entered into supply agreements with over 34 third-party solar cell customers and are in active negotiation with several potential customers to supply our solar cells.

In line with the overall strategy of Fuji Solar and its controlling shareholder WWB Corporation, a Japanese company, we are preparing ourselves for the manufacturing of solar PV modules for sales in the United States, allowing our affiliate VSUN to focus on ex-U.S. PV module markets. Specifically, we have leased a facility located in Texas to accommodate our solar module production with an expected annual capacity of 6.5GW by 2029. The first 1 GW solar module plant at this facility in in Texas has begun the trial production and is expected to gradually increase deliveries of solar modules by the end of 2025. We plan to supply our solar PV modules, initially in collaboration with VSUN, leveraging its experience and certification. Later, we will independently manufacture and supply PV modules under VSUN brand acquired by us in September 2025. Our module facility in the Houston metropolitan area has commenced trial production. We also plan to continue our collaboration with VSUN to support our PV module supply under VSUN brand based on market demands and our business development.Thereafter, we also plan to construct a solar cell plant in the U.S. and our own wafer slicing plant at a selected location, and continue to be dedicated to becoming a reliable integrated service solar solutions provider in the United States and globally.

We derive competitive edge from our relationship with Fuji Solar, WWB, Abalance and VSUN. Fuji Solar, our affiliate, is a majority-owned subsidiary of WWB, a Japanese company that develops photo voltaic systems and sells construction equipment and related parts. WWB is a subsidiary of Abalance, a public company listed on the Tokyo Stock Exchange that has extensive experience and expertise in the investment, development, construction and operation of solar energy projects globally. VSUN, our affiliate and a majority-owned subsidiary of Fuji Solar, is a specialized PV modules producer with an established presence and brand recognition in regions including the United States, Europe and Asia. Since the third quarter of 2019, VSUN has been listed by Bloomberg New Energy Finance (NEF) as one of Tier 1 PV module manufacturers. VSUN’s solar modules are recognized as the core assets of efficient and reliable PV power stations, which would be beneficial for solar market players who utilize VSUN’s solar modules to obtain financing from such banks and financial institutions. In September, TOYO acquired the VSUN brand from VSUN The acquisition supports TOYO’s strategic expansion into the U.S market, complementing its existing manufacturing footprint for solar cells in Vietnam and Ethiopia. We believe that, with the acquisition of VSUN brand, by leveraging VSUN’s successful experience and market insights, as well as its strong presence and reputation in the solar industry, we are able to quickly obtain access to the U.S. market with minimal upfront marketing and brand promotion, and establish ourselves as a trusted PV module supplier in the United States and even globally.

We inherited corporate culture from Fuji Solar, WWB and Abalance, which we believe will enable us to strive for and sustain operational excellence. This Japanese-style corporate culture values discipline and a down-to-earth attitude, aligns corporate growth and personal career goals, and encourages employees to be self-driven. Further, we intend to implement the Japanese-style management system that was proven to be effective by Fuji Solar, WWB, Abalance and VSUN, which is centered around the manufacturing sites and intended to resolve issues arising from the sites in the most efficient and effective manner. We believe sharing the same corporate culture and management style with Fuji Solar, WWB, Abalance and VSUN and leveraging their successful experience will enable us to quickly grow as an independent entity and achieve our operational objectives.

As a result, we are a “controlled company” within the meaning of applicable Nasdaq listing rules. Under these rules, a company of which more than 50% of the voting power for the election of directors is held by an individual, group or another company is a “controlled company.” For so long as we remain a “controlled company,” we may elect not to comply with certain corporate governance requirements, including the requirements:

●

that a majority of the board of directors consists of independent directors;

●

for an annual performance evaluation of the nominating and corporate governance and compensation committees;

●

that we have a nominating and corporate governance committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and

●

that we have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibility.

●

our results of operations and cash flow;

our expected financial performance and working capital needs;

●

our future prospects;

●

our capital expenditures and other investment plans

●

other investment and growth plans;

●

dividend yields of comparable companies globally;

●

restrictions on payment of dividend that may be imposed on us by financing arrangements; and

●

the general economic and business conditions and other factors deemed relevant by our board of directors and statutory restrictions on the payment of dividends.

Liquidation

On the winding up of TOYO, if the assets available for distribution amongst our shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of winding up, the surplus shall be distributed amongst our shareholders in proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of all monies payable to us for unpaid calls or otherwise. If our assets available for distribution are insufficient to repay the whole of the share capital, the assets will be distributed so that the losses are borne by our shareholders in proportion to the par value of the shares held by them.

DESCRIPTION OF DEBT SECURITIES

As used in this prospectus, the term “debt securities” means the debentures, notes, bonds and other evidences of indebtedness that we may issue from time to time. The debt securities will either be senior debt securities, senior subordinated debt or subordinated debt securities. We may also issue convertible debt securities. Debt securities issued under an indenture (which we refer to herein as an Indenture) will be entered into between us and a trustee to be named therein. It is likely that convertible debt securities will not be issued under an Indenture.

The Indenture or forms of Indentures, if any, will be filed as exhibits to the registration statement of which this prospectus is a part.

As you read this section, please remember that for each series of debt securities, the specific terms of your debt security as described in the applicable prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in the summary below. The statement we make in this section may not apply to your debt security.

Events of Default Under the Indenture

Unless we provide otherwise in the prospectus supplement or free writing prospectus applicable to a particular series of debt securities, the following are events of default under the indentures with respect to any series of debt securities that we may issue:

●

if we fail to pay the principal or premium, if any, when due and payable at maturity, upon redemption or repurchase or otherwise;

●

if we fail to pay interest when due and payable and our failure continues for certain days;

●

if we fail to observe or perform any other covenant contained in the Securities of a Series or in this Indenture, and our failure continues for certain days after we receive written notice from the trustee or holders of at least certain percentage in aggregate principal amount of the outstanding debt securities of the applicable series. The written notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default”;

●

if specified events of bankruptcy, insolvency or reorganization occur; and

●

if any other event of default provided with respect to securities of that series, which is specified in a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate as defined in the Form of Indenture.

We covenant in the Form of Indenture to deliver a certificate to the trustee annually, within certain days after the close of the fiscal year, to show that we are in compliance with the terms of the indenture and that we have not defaulted under the indenture.

Nonetheless, if we issue debt securities, the terms of the debt securities and the final form of indenture will be provided in a prospectus supplement. Please refer to the prospectus supplement and the form of indenture attached thereto for the terms and conditions of the offered debt securities. The terms and conditions may or may not include whether or not we must furnish periodic evidence showing that an event of default does not exist or that we are in compliance with the terms of the indenture.

The statements and descriptions in this prospectus or in any prospectus supplement regarding provisions of the Indentures and debt securities are summaries thereof, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the Indentures (and any amendments or supplements we may enter into from time to time which are permitted under each Indenture) and the debt securities, including the definitions therein of certain terms.

General

Unless otherwise specified in a prospectus supplement, the debt securities will be direct secured or unsecured obligations of our Company. The senior debt securities will rank equally with any of our other unsecured senior and unsubordinated debt. The subordinated debt securities will be subordinate and junior in right of payment to any senior indebtedness.

We may issue debt securities from time to time in one or more series, in each case with the same or various maturities, at par or at a discount. Unless indicated in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of the issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the applicable Indenture and will be equal in ranking.

Should an indenture relate to unsecured indebtedness, in the event of a bankruptcy or other liquidation event involving a distribution of assets to satisfy our outstanding indebtedness or an event of default under a loan agreement relating to secured indebtedness of our company or its subsidiaries, the holders of such secured indebtedness, if any, would be entitled to receive payment of principal and interest prior to payments on the senior indebtedness issued under an Indenture.

Prospectus Supplement

Each prospectus supplement will describe the terms relating to the specific series of debt securities being offered. These terms will include some or all of the following:

●

the title of debt securities and whether they are subordinated, senior subordinated or senior debt securities;

●

any limit on the aggregate principal amount of debt securities of such series;

●

Holders of such debt securities may receive a principal amount on any principal payment date, or interest payments on any interest payment date, that are greater or less than the amount of principal or interest otherwise payable on such dates, depending upon the value on such dates of applicable currency, commodity, equity index or other factors. The applicable prospectus supplement will contain information as to how we will determine the amount of principal or interest payable on any date, as well as the currencies, commodities, equity indices or other factors to which the amount payable on that date relates and certain additional tax considerations.

DESCRIPTION OF WARRANTS

We may issue warrants to purchase our Ordinary Shares. Warrants may be issued independently or together with any other securities that may be sold by us pursuant to this prospectus or any combination of the foregoing and may be attached to, or separate from, such securities. To the extent warrants that we issue are to be publicly-traded, each series of such warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. While the terms we have summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe in particular the terms of any series of warrants that we may offer in more detail in the applicable prospectus supplement and any applicable free writing prospectus. The terms of any warrants offered under a prospectus supplement may differ from the terms described below.

We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from another report that we file with the SEC, the form of the warrant and/or warrant agreement, if any, which may include a form of warrant certificate, as applicable that describes the terms of the particular series of warrants we may offer before the issuance of the related series of warrants. We may issue the warrants under a warrant agreement that we will enter into with a warrant agent to be selected by us. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any registered holders of warrants or beneficial owners of warrants. The following summary of material provisions of the warrants and warrant agreements is subject to, and qualified in its entirety by reference to, all the provisions of the form of warrant and/or warrant agreement and warrant certificate applicable to a particular series of warrants. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete form of warrant and/or the warrant agreement and warrant certificate, as applicable, that contain the terms of the warrants.

The particular terms of any issue of warrants will be described in the prospectus supplement relating to the issue. Those terms may include:

●

the title of the warrants;

●

the price or prices at which the warrants will be issued;

●

the designation, amount and terms of the securities or other rights for which the warrants are exercisable;

●

the designation and terms of the other securities, if any, with which the warrants are to be issued and the number of warrants issued with each other security;

●

the aggregate number of warrants;

●

any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants;

●

the price or prices at which the securities or other rights purchasable upon exercise of the warrants may be purchased;

●

if applicable, the date on and after which the warrants and the securities or other rights purchasable upon exercise of the warrants will be separately transferable;

●

a discussion of any material U.S. federal income tax considerations applicable to the exercise of the warrants;

●

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

●

the maximum or minimum number of warrants that may be exercised at any time;

●

information with respect to book-entry procedures, if any; and

●

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

Exercise of Warrants

Each warrant will entitle the holder of warrants to purchase the number of Ordinary Shares of the relevant class or series at the exercise price stated or determinable in the prospectus supplement for the warrants. Warrants may be exercised at any time up to the close of business on the expiration date shown in the applicable prospectus supplement, unless otherwise specified in such prospectus supplement. After the close of business on the expiration date, if applicable, unexercised warrants will become void. Warrants may be exercised in the manner described in the applicable prospectus supplement. When the warrant holder makes the payment and properly completes and signs the warrant certificate at the corporate trust office of the warrant agent, if any, or any other office indicated in the prospectus supplement, we will, as soon as possible, forward the securities or other rights that the warrant holder has purchased. If the warrant holder exercises less than all of the warrants represented by the warrant certificate, we will issue a new warrant certificate for the remaining warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

Prior to the exercise of any warrants to purchase Ordinary Shares of the relevant class or series, holders of the warrants will not have any of the rights of holders of Ordinary Shares purchasable upon exercise, including the right to vote or to receive any payments of dividends or payments upon our liquidation, dissolution or winding up on the Ordinary Shares purchasable upon exercise, if any.

DESCRIPTION OF RIGHTS

We may issue rights to purchase our securities. The rights may or may not be transferable by the persons purchasing or receiving the rights. In connection with any rights offering, we may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such rights offering. Each series of rights will be issued under a separate rights agent agreement to be entered into between us and one or more banks, trust companies or other financial institutions, as rights agent, that we will name in the applicable prospectus supplement. The rights agent will act solely as our agent in connection with the rights and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights.

The prospectus supplement relating to any rights that we offer will include specific terms relating to the offering, including, among other matters:

●

the date of determining the security holders entitled to the rights distribution;

●

the aggregate number of rights issued and the aggregate amount of securities purchasable upon exercise of the rights;

●

the exercise price;

●

the conditions to completion of the rights offering;

●

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

●

any applicable federal income tax considerations.

Each right would entitle the holder of the rights to purchase for cash the principal amount of securities at the exercise price set forth in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised rights will become void.

If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than our security holders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

DESCRIPTION OF UNITS

The following description, together with the additional information we may include in any applicable prospectus supplement, summarizes the material terms and provisions of the units that we may offer under this prospectus. While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement and any related free writing prospectus. The terms of any units offered under a prospectus supplement may differ from the terms described below. However, no prospectus supplement will 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.

We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from another report we file with the SEC, the form of unit agreement that describes the terms of the series of units we may offer under this prospectus, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete unit agreement and any supplemental agreements that contain the terms of the units.

We may issue units consisting of any combination of the other types of securities offered under this prospectus in one or more series. We may evidence each series of units by unit certificates that we may issue under a separate agreement. We may enter into unit agreements with a unit agent. Each unit agent, if any, may be a bank or trust company that we select. We will indicate the name and address of the unit agent, if any, in the applicable prospectus supplement relating to a particular series of units. Specific unit agreements, if any, will contain additional important terms and provisions. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from a current report that we file with the SEC, the form of unit and the form of each unit agreement, if any, relating to units offered under this prospectus.

If we offer any units, certain terms of that series of units will be described in the applicable prospectus supplement, including, without limitation, the following, as applicable

●

the title of the series of units;

●

identification and description of the separate constituent securities comprising the units;

●

the price or prices at which the units will be issued;

●

the date, if any, on and after which the constituent securities comprising the units will be separately transferable;

●

a discussion of certain United States federal income tax considerations applicable to the units; and

●

any other material terms of the units and their constituent securities.

The provisions described in this section, as well as those described under “Description of Share Capital – Ordinary Shares” and “Description of Warrants” will apply to each unit and to any Ordinary Shares or warrant included in each unit, respectively.

Issuance in Series

We may issue units in such amounts and in numerous distinct series as we determine.

PLAN OF DISTRIBUTION

We may sell the securities offered through this prospectus (i) to or through underwriters or dealers, (ii) directly to purchasers, including our affiliates, (iii) through agents, or (iv) through a combination of any these methods. The securities may be distributed at a fixed price or prices, which may be changed, market prices prevailing at the time of sale, prices related to the prevailing market prices, or negotiated prices. The prospectus supplement will include the following information:

●

the terms of the offering;

●

the names of any underwriters or agents;

●

the name or names of any managing underwriter or underwriters;

●

the purchase price of the securities;

●

any over-allotment options under which underwriters may purchase additional securities from us;

●

the net proceeds from the sale of the securities;

●

any delayed delivery arrangements;

●

any underwriting discounts, commissions and other items constituting underwriters’ compensation;

●

any initial public offering price;

●

any discounts or concessions allowed or reallowed or paid to dealers;

●

any commissions paid to agents; and

●

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

Sale Through Underwriters or Dealers

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement. If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.

We will provide in the applicable prospectus supplement any compensation we will pay to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers.

Direct Sales and Sales Through Agents

We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.

We may also sell equity securities covered by this registration statement in an “at the market offering” as defined in Rule 415 under the Securities Act. Such offering may be made into an existing trading market for such securities in transactions at other than a fixed price, either:

●

on or through the facilities of the Nasdaq Capital Market or any other securities exchange or quotation or trading service on which such securities may be listed, quoted or traded at the time of sale; and/or

●

to or through a market maker other than on the Nasdaq Capital Market or such other securities exchanges or quotation or trading services.

Such “at the market offerings”, if any, may be conducted by underwriters acting as principal or agent.

Delayed Delivery Contracts

If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

Market Making, Stabilization and Other Transactions

Unless the applicable prospectus supplement states otherwise, other than our Ordinary Shares, all securities we offer under this prospectus will be a new issue and will have no established trading market. We may elect to list offered securities on an exchange or in the over-the-counter market. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Securities Exchange Act. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

General Information

Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act. Our agents, underwriters, and dealers, or their affiliates, may be customers of, engage in transactions with or perform services for us, in the ordinary course of business.

LEGAL MATTERS

Except as otherwise set forth in the applicable prospectus supplement, certain legal matters in connection with the securities offered pursuant to this prospectus will be passed upon for us by Robinson & Cole LLP to the extent governed by the laws of the State of New York, and by Harney Westwood & Riegels to the extent governed by the laws of the Cayman Islands. If legal matters in connection with offerings made pursuant to this prospectus are passed upon by counsel to underwriters, dealers or agents, such counsel will be named in the applicable prospectus supplement relating to any such offering.

ENFORCEABILITY OF CIVIL LIABILITIES

We are incorporated under the laws of the Cayman Islands as an exempted company with limited liability. We are incorporated in the Cayman Islands to take advantage of certain benefits associated with being a Cayman Islands exempted company, such as:

●

political and economic stability;

●

an effective judicial system;

●

tax neutrality;

●

the absence of exchange control or currency restrictions; and

●

the availability of professional and support services.

However, certain disadvantages accompany incorporation in the Cayman Islands. These disadvantages include but are not limited to:

●

the Cayman Islands has a less developed body of securities laws as compared to the United States and these securities laws provide significantly less protection to investors as compared to those of the United States; and

●

Cayman Islands companies may not have standing to sue before the federal courts of the United States.

Our amended and restated memorandum and articles of association do not contain provisions requiring that disputes, including those arising under the securities laws of the United States, between us, our officers, directors and shareholders, be arbitrated.

We have appointed Puglisi & Associates, located at 850 Library Avenue, Suite 204, Newark, Delaware 19711, as our agent upon whom process may be served in any action brought against us under the securities laws of the United States.

A majority of our directors are nationals or residents of jurisdictions other than the United States and most of their assets are located outside the United States. As a result, it may be difficult for a shareholder to effect service of process within the United States upon these individuals, or to bring an action against us or these individuals in the United States, or to enforce 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.

Cayman Islands

We have been advised by Harney Westwood & Riegels that although there is no statutory enforcement in the Cayman Islands of judgments obtained in the federal or state courts of the United States (and the Cayman Islands are not a party to any treaties for the reciprocal enforcement or recognition of such judgments), the Grand Court of the Cayman Islands will at common law enforce final and conclusive in personam judgments of state and/or federal courts of the United States of America, or the “Foreign Court”, of a debt or definite sum of money against TOYO (other than a sum of money payable in respect of taxes or other charges of a like nature, a fine or other penalty (which may include a multiple damages judgment in an anti-trust action) or where enforcement would be contrary to public policy). The Grand Court of the Cayman Islands may also at common law enforce final and conclusive in personam judgments of the Foreign Court that are non-monetary against TOYO, for example, declaratory judgments ruling upon the true legal owner of shares in a Cayman Islands company. The Grand Court of the Cayman Islands will exercise its discretion in the enforcement of non-money judgments by having regard to the circumstances, such as considering whether the principles of comity apply. To be treated as final and conclusive, any relevant judgment must be regarded as res judicata by the Foreign Court. A debt claim on a foreign judgment must be brought within six years of the date of the judgment, and arrears of interest on a judgment debt cannot be recovered after six years from the date on which the interest was due. The courts of the Cayman Islands are unlikely to enforce a judgment obtained from the Foreign Court under civil liability provisions of U.S. federal securities law if such a judgment is found by the courts of the Cayman Islands to give rise to obligations to make payments that are penal or punitive in nature. Such a determination has not yet been made by the Grand Court of the Cayman Islands. A court of the Cayman Islands may stay enforcement proceedings if concurrent proceedings are being brought elsewhere. A judgment entered in default of appearance by a defendant who has had notice of the Foreign Court’s intention to proceed may be final and conclusive notwithstanding that the Foreign Court has power to set aside its own judgment and despite the fact that it may be subject to an appeal the time-limit for which has not yet expired. The Grand Court of the Cayman Islands may safeguard the defendant’s rights by granting a stay of execution pending any such appeal and may also grant interim injunctive relief as appropriate for the purpose of enforcement.

Singapore

SinCo is incorporated under the laws of the Republic of Singapore, and certain of its officers and directors are residents outside the United States. There is no treaty between the U.S. and Singapore providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters and a final judgment for the payment of money rendered by any federal or state court in the U.S. based on civil liability, whether or not predicated solely upon the federal securities laws, would, therefore, not be automatically enforceable in Singapore. In making a determination as to enforceability of a foreign judgment, the Singapore courts need to be satisfied that the foreign judgment was final and conclusive and on the merits of the case, given by a court of law of competent jurisdiction, and was expressed to be for a fixed sum of money. In general, a foreign judgment would be enforceable in Singapore unless procured by fraud, or if the proceedings in which such judgments were obtained were not conducted in accordance with principles of natural justice, or if the enforcement thereof would be contrary to the public policy of Singapore, or if the judgment would conflict with earlier judgments from Singapore or earlier foreign judgments recognized in Singapore, or if the judgment would amount to the direct or indirect enforcement of foreign penal, revenue or other public laws.

Civil liability provisions of the federal and state securities law of the U.S. permit the award of punitive damages against SinCo and its directors and officers. The Singapore courts do not allow the enforcement of foreign judgments which amount to the direct or indirect enforcement of foreign penal, revenue or other public laws. It is uncertain as to whether a judgment of the courts of the U.S. awarding such punitive damages would be regarded by the Singapore courts as being pursuant to foreign, penal, revenue or other public laws. Such determination has yet to be conclusively made by a Singapore court in a reported decision.

Vietnam

Vietnam is a party to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (the “New York Convention”), and a few bilateral treaties relating to the recognition and enforcement of foreign judgments but not to any other multinational treaty in this regard. Foreign arbitral awards can be enforceable in Vietnam under the New York Convention after being recognized by Vietnamese courts in accordance with statutory procedures. However, in principle, Vietnam’s Civil Procedure Code provides that a civil judgment or decision of a foreign court is enforceable in Vietnam only if there is a treaty in this regard between Vietnam and such foreign country (including international treaties) or on a reciprocal basis. Vietnam’s Civil Procedure Code also sets out several grounds for Vietnamese courts to refuse the recognition and enforcement of foreign judgments and decisions or foreign arbitral awards. Therefore, it may be difficult to enforce in Vietnam any judgment or decision issued by a U.S. court against TOYO Solar or its directors and officers who are citizens of Vietnam.
