MARKET AND INDUSTRY DATA

The data included and incorporated by reference in this prospectus supplement regarding markets, ranking and other industry information are based on reports of government agencies or published industry sources, and our own internal estimates are based on our management's knowledge and experience in the markets in which we operate. Data regarding the industry in which we compete and our market position and market share within this industry are inherently imprecise and are subject to significant business, economic and competitive uncertainties beyond our control, but we believe they generally indicate size, position and market share within this industry. Our own estimates are based on information obtained from our customers, suppliers, trade and business organizations and other contacts in the markets we operate. We are responsible for all of the disclosure contained or incorporated by reference in this prospectus supplement, and we believe these estimates to be accurate as of the date of this prospectus supplement or such other date stated in this prospectus supplement or such date as of the document incorporated herein. However, this information may prove to be inaccurate because of the method by which we obtained some of the data for the estimates or because this information cannot always be verified with complete certainty due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties. While we believe that each of the publications used or incorporated by reference in this prospectus supplement are prepared by reputable sources, neither we nor the underwriters have independently verified market and industry data from third-party sources. While we believe our internal company research and estimates are reliable, such research and estimates have not been verified by any independent source. In addition, assumptions and estimates of our and our industry's future performance are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on March 27, 2026 ("Annual Report"), which is incorporated by reference into this prospectus supplement. These and other factors could cause our future performance to differ materially from our assumptions and estimates. See "Cautionary Note Regarding Forward-Looking Statements." As a result, you should be aware that market, ranking, and other similar industry data included or incorporated by reference in this prospectus supplement, and estimates and beliefs based on that data may not be reliable. Neither we nor the underwriters can guarantee the accuracy or completeness of any such information contained or incorporated by reference in this prospectus supplement.

S-1

BASIS OF PRESENTATION

Unless otherwise indicated or the context otherwise requires, financial data in this prospectus supplement reflects the business and operations of the Company and its consolidated subsidiaries. Amounts included, or incorporated by reference, in this prospectus are presented in U.S. dollars rounded to the nearest million, unless otherwise noted. Certain amounts presented in tables are subject to rounding adjustments and, as a result, the totals in such tables may not sum. The accounting policies set out in the audited consolidated financial statements incorporated by reference in this prospectus have been consistently applied to all periods presented.

NON-GAAP FINANCIAL MEASURES

This prospectus supplement contains certain non-GAAP financial measures. EBITDA, EBITDA Margin, ROE (Annualized), Capital Adequacy Ratio, D/E, BPS and Net Interest-Bearing Debt, are non-GAAP financial measures that we use in evaluating our operating results and for financial and operational decision-making purposes. We define EBITDA as income from operations before depreciation and amortization expense and impairment loss. We define EBITDA Margin as EBITDA divided by total revenues, net. We define ROE (Annualized) as net income attributable to SBC Medical Group Holdings Incorporated divided by the average of SBC Medical Group Holdings Incorporated's stockholders' equity (beginning period and end of the period). We define Capital Adequacy Ratio as total stockholders' equity divided by total assets. We define D/E as interest-bearing debt divided by total stockholders' equity. We define BPS as total stockholders' equity divided by shares outstanding. We define Net Interest-Bearing Debt as interest-bearing debt less cash and cash equivalents. We believe that the non-GAAP financial measures provide useful information about the Company's results of operations, enhance the overall understanding of our past performance and future prospects and allow for greater visibility with respect to key metrics used by our management in its financial and operational decision-making. The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. The non-GAAP financial measures have limitations as analytical tools, and when assessing our operating performance, cash flows or liquidity, investors should not consider them in isolation, or as a substitute for income from operations, cash flows provided by operating activities or other consolidated statements of operations and cash flows data prepared in accordance with U.S. GAAP. We mitigate these limitations by reconciling the non-GAAP financial measures to the most comparable U.S. GAAP performance measures, all of which should be considered when evaluating our performance. For more information on the non-GAAP financial measures and a reconciliation of the most directly comparable GAAP measures, see "Summary of Historical Consolidated Financial Information and Other Data."

Our Company

History

We were originally incorporated in Delaware on March 11, 2022 under the name "Pono Capital Two, Inc.," referred to herein as "Pono," as a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses.

On August 9, 2022, Pono consummated its IPO of 11,500,000 units (the "Units" and, with respect to the Class A common stock included in the Units being offered, the "Public Shares" and with respect to the warrants included in the Units, the "Public Warrants") (the "Pono IPO").

Simultaneously with the consummation of the closing of the Pono IPO, Pono consummated the private placement of an aggregate of 634,375 units (the "Placement Units") at a price of $10.00 per Placement Unit in a private placement to the Sponsor (the "Private Placement").

On September 26, 2022, the Class A common stock and Public Warrant included in the Units began separate trading on The Nasdaq Global Market under the symbols "PTWO," and "PTWOW," respectively.

On January 31, 2023, Pono entered into an Agreement and Plan of Merger (as subsequently amended from time to time, the "Merger Agreement") with Pono Two Merger Sub, Inc., a Delaware corporation ("Merger Sub") and then a wholly-owned subsidiary of Pono, SBC Medical Group, Inc., then named SBC Medical Group Holdings Incorporated, a Delaware corporation ("Legacy SBC"), Mehana Capital LLC, a Delaware limited liability company ("Sponsor" or "Purchaser Representative") in its capacity as the representative of the stockholders of Pono, and Yoshiyuki Aikawa in his personal capacity and his capacity as the representative of the stockholders of Legacy SBC ("Seller Representative").

On September 17, 2024, the closing (the "Closing") of the merger (the "Merger") and other transactions contemplated thereby (collectively, the "Business Combination") took place and the Merger was consummated with Merger Sub merging with and into Legacy SBC with Legacy SBC surviving the Merger as a wholly-owned subsidiary of Pono, and Pono then changed its name to SBC Medical Group Holdings Incorporated and on September 17, 2024, Legacy SBC changed its named to SBC Medical Group, Inc.

Effective September 17, 2024, Pono's units ceased trading, and effective September 18, 2024, SBC's common stock began trading on the Nasdaq Global Market under the symbol "SBC" and the public warrants began trading on the Nasdaq Capital Market under the symbol "SBCWW."

As a result of the Closing of the Merger and the Business Combination, the business of SBC Medical Group, Inc. ("Legacy SBC"), became the business of the Company.

Business Overview

The Company is a management company with offices in Irvine, California and Tokyo, Japan, and, through our subsidiaries, we provide management services to aesthetic clinics in Japan that are owned and operated by medical corporations and other franchisees we support. We also own and operate clinics in Vietnam and Singapore, and we are pursuing U.S. market initiatives primarily through strategic investments and alliances. The history of Legacy SBC began with the establishment of L'Ange Cosmetique Co., Ltd. in 2003 and SBCMG (formerly Aikawa Medical) in 2017 for the purpose of providing management services to medical corporations and the medical clinics of the medical corporations. The history of the medical corporations and the medical clinics began in 2000 with the opening of Shonan Beauty Clinic in Fujisawa City, Japan, where Dr. Aikawa opened in private practice. Subsequently, Dr. Aikawa opened clinics in Yokohama in 2001 and Shinjuku in 2003, incorporated as Medical Corporation Shobikai in 2004, acquired a medical corporation named Medical Corporation Kowakai in 2009 and Medical Corporation Nasukai in 2009.

The Company and its subsidiaries are primarily focused on providing comprehensive management services to franchisee clinics. These services include advertising and marketing across various platforms (such as social media networks), staff management (such as recruitment and training), booking and reservation services for franchisee clinic customers. We also support franchisee clinics through assistance with employee housing rentals and facility rentals, leasehold improvement and design of clinics, medical equipment and medical consumables procurement (resale), the provision of cosmetic products to clinics for resale to clinic customers, licensure of the use of patent-pending and non-patented medical technologies, trademark and brand use, IT software solutions (including but not limited to remote medical consultations), management of the customer rewards program (customer loyalty point program), and payment tools.

In 2017, we began providing our management services to our franchisee treatment centers. Unless otherwise indicated, the operational metrics in this section are as of December 31, 2025. As of December 31, 2025, the Company and its subsidiaries provided management services to a total of 237 franchisee treatment centers located in Japan, including 5 independently operated clinics in Japan under separate franchise arrangements. In addition, we operate 21 treatment centers in Singapore through Aesthetic Healthcare Holdings ("AHH") and its subsidiaries. The Company also (i) owned and operated 1 treatment center under its "SBC" brand name in Ho Chi Minh City, Vietnam, as well as (ii) previously provided management services to 1 treatment center under its "SBC" brand name in Irvine, California in the United States (the "CA Clinic"), which was owned and operated by the related party, until it was permanently closed at the end of May 2025, and we no longer provide management services to any clinic in the United States. However, in the United States, we have pursued market entry through a strategic minority equity investment in OT Midco, through which we hold an indirect minority interest in the OrangeTwist business ("OT"), and we may explore potential commercial arrangements with OT on a non-binding basis. OT operates 24 treatment centers across the United States, rather than through directly owned and operated clinics or management service arrangements. Our franchisee treatment centers in Japan, together with our treatment centers in Singapore and Vietnam, provide an array of surgical and non-surgical medical services that vary based upon location, including cosmetic surgery, dermatology, and dentistry. These medical services include but are not limited to breast augmentation, liposuction, rejuvenation treatments (including treatment of wrinkles, acne, scars, cellulite, excess fat, discoloration, and signs of aging), laser skin toning and spot removal, eyes double fold surgery, rhinoplasty, treatment of osmidrosis and hyperhidrosis, hair transplants, gynecological formation treatments, laser hair removal, face line surgeries, cosmetic dental procedures, tattoo removal, lasik eye surgery, lateral canthoplasty, brow lift procedures, androgenetic alopecia treatment, and cheek sagging prevention methods.

To further our growth and global expansion, we have recently completed or announced several strategic transactions and initiatives:

In November 2024, we acquired a 100% equity interest in Aesthetic Healthcare Holdings ("AHH") and its subsidiaries, which are incorporated in Singapore and principally engaged in medical aesthetics business, for cash consideration of SGD$7.8 million (equivalent to approximately US$5.8 million). As a result of this acquisition, we operate clinics in Singapore owned and operated through AHH and its subsidiaries.
In July 2025, we acquired 100% equity interest in MB career lounge, Co., Ltd. ("MB career lounge"), a company providing comprehensive management supporting services for medical institutions in Japan, including medical professional recruiting and operational consulting, with a cash consideration of JPY 2,040 million (approximately $14.2 million). In the same month, we appointed Dr. Steven R. Cohen as Medical Strategy Advisor to support our global expansion initiatives and enhance our medical quality and physician training programs.
In November 2025, we entered into a consulting agreement with BLEZ ASIA Co., Ltd., which operates more than 20 clinics and pharmacies in Thailand, to support our entry into Thailand, including management support for a new dermatology-focused clinic BLEZ is preparing to open in Bangkok.
S-4
In December 2025, we acquired a controlling interest in Waqoo, Inc. ("Waqoo"), a company listed on the Tokyo Stock Exchange Growth Market and a medical research and development company specializing in regenerative medicine technologies. We initially conducted a tender offer for Waqoo's common stock from November 14, 2025 through December 12, 2025, through which we acquired 575,052 shares, or 16.27% of the voting rights. Concurrently, on December 19, 2025, we acquired additional shares through an off-market transaction from Yoshiyuki Aikawa, the Company's CEO, a related party to the Company and the then-largest shareholder of Waqoo, resulting in our total ownership of Waqoo's voting rights exceeding 50% and Waqoo becoming our consolidated subsidiary.
Additionally, on December 29, 2025, we acquired an approximately 18.2% voting interest in OT Midco Holdings, LLC ("OT Midco"), a holding company through which we hold an indirect minority interest in the OrangeTwist business ("OrangeTwist"), a lifestyle medicine and medical aesthetics provider operating treatment centers across the United States, for a total cash consideration of $20 million. In addition, we committed to make an additional cash contribution of $5.0 million in December 2026 for newly issued common units of OT Midco. We account for this investment under the equity method due to our board representation and participation in policy-making processes.
As part of our ongoing expansion strategy, we also continuously evaluate other potential investments and acquisitions. For example, in May 2025, we announced that we began reviewing a potential acquisition of Risenet Co., Ltd., and, as of the date of our Annual Report, we have not entered into a definitive agreement.

Since our inception, we have been committed to delivering high quality management services to our franchisee clinics and other alliance clinics. We believe our team of highly qualified and experienced professionals has underpinned our strong reputation as we continue to provide multifaceted management services to our franchisee clinics.

As of December 31, 2025, we had 283 clinic locations, including our franchisee clinics. During the fiscal year ended December 31, 2025, we estimate that we had approximately 6.6 million annual customer visits at our clinic locations and franchisee clinics, of which we estimate that approximately 2.1 million were unique customers. During the same period, we estimate that our franchisee clinics had an average repeat customer rate (measured as customers visiting at least two times and excluding free counseling) of over 72% and an estimated average revenue per visit of approximately $316 (calculated after giving effect to points and discounts and excluding free counseling).

Implications of Being a Controlled Company

The Company is a "controlled company" within the meaning of the applicable rules of Nasdaq and, as a result, we qualify for exemptions from certain corporate governance requirements. If the Company relies on these exemptions, its stockholders will not have the same protections afforded to stockholders of companies that are subject to such requirements. As of April 16, 2026, Dr. Aikawa and entities he controls collectively control approximately 85.2% of the voting power of our outstanding common stock. After this offering, Dr. Aikawa and entities he controls would collectively control approximately % (or %, if the underwriters fully exercise their option to purchase additional shares) of the voting power of our outstanding common stock. Accordingly, the Company is, and following this offering will continue to be, a "controlled company" within the meaning of applicable rules of Nasdaq. 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" and may elect not to comply with certain corporate governance requirements, including the requirements:

that a majority of the board consists of independent directors;
for an annual performance evaluation of the nominating and corporate governance and compensation committees;
that the controlled company has 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 the controlled company has a compensation committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibility.

While the Company does not intend to rely on these exemptions, the Company may use these exemptions now or in the future. As a result, the Company's stockholders may not have the same protections afforded to stockholders of companies that are subject to all of the Nasdaq corporate governance requirements.

(1) EBITDA, EBITDA Margin, ROE (Annualized), Capital Adequacy Ratio, D/E, BPS and Net Interest-Bearing Debt, are non-GAAP financial measures that we use in evaluating our operating results and for financial and operational decision-making purposes. We define EBITDA as income from operations before depreciation and amortization expense and impairment loss. We define EBITDA Margin as EBITDA divided by total revenues, net. We define ROE (Annualized) as net income attributable to SBC Medical Group Holdings Incorporated divided by the average of SBC Medical Group Holdings Incorporated's stockholders' equity (beginning period and end of the period). We define Capital Adequacy Ratio as total stockholders' equity divided by total assets. We define D/E as interest-bearing debt divided by total stockholders' equity. We define BPS as total stockholders' equity divided by shares outstanding. We define Net Interest-Bearing Debt as interest-bearing debt less cash and cash equivalents. We believe that the non-GAAP financial measures provide useful information about the Company's results of operations, enhance the overall understanding of our past performance and future prospects and allow for greater visibility with respect to key metrics used by our management in its financial and operational decision-making. The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. The non-GAAP financial measures have limitations as analytical tools, and when assessing our operating performance, cash flows or liquidity, investors should not consider them in isolation, or as a substitute for income from operations, cash flows provided by operating activities or other consolidated statements of operations and cash flows data prepared in accordance with U.S. GAAP. We mitigate these limitations by reconciling the non-GAAP financial measures to the most comparable U.S. GAAP performance measures, all of which should be considered when evaluating our performance.

RISK FACTORS

Before you invest in our common stock, in addition to the other information in this prospectus supplement and accompanying prospectus, you should carefully read and consider the following risk factors together with the information included or incorporated by reference herein and therein, including under "Risk Factors" contained in Part I, Item 1A of our Annual Report. Each of the risks described in these documents could materially and adversely affect our business, financial condition, liquidity, results of operations and prospects, and could result in a partial or complete loss of your investment.

Risks Related to the Offering and Our Common Stock

An active market for our securities may not develop, which would adversely affect the liquidity and price of our securities.

Our common stock began trading on the Nasdaq Global Market under the symbol "SBC" on September 18, 2024. The price of our securities may vary significantly due to factors specific to the Company as well as to general market or economic conditions. Furthermore, an active trading market for our securities may never develop or, if developed, it may not be sustained. You may be unable to sell your securities unless a market can be established and sustained.

Nasdaq may delist our securities from trading on its exchange, which could limit investors' ability to make transactions in our securities and subject the Company to additional trading restrictions.

Our common stock began trading on the Nasdaq Global Market under the symbol "SBC" on September 18, 2024. However, we cannot assure you that our securities will continue to be listed on Nasdaq in the future. In order to continue listing its securities on Nasdaq, the Company must maintain certain financial, distribution and stock price levels. Generally, the Company must maintain a minimum number of holders of its securities (including requirements relating to the minimum number of holders of its securities).

If Nasdaq delists the Company's securities from trading on its exchange and the Company is not able to list its securities on another national securities exchange, we expect our securities could be quoted on an over-the-counter market. If this were to occur, the Company could face significant material adverse consequences, including:

a limited availability of market quotations for its securities;
reduced liquidity for its securities;
a determination that our common stock is a "penny stock" which will require brokers trading in the common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities;
a limited amount of news and analyst coverage; and
a decreased ability to issue additional securities or obtain additional financing in the future.

The market price of our common stock may decline.

The market price of our common stock may decline for a number of reasons including if:

investors react negatively to our operating results or future prospects;
our actual financial and operating results are not consistent with the expectations of financial or industry analysts; or
we do not achieve the growth as rapidly or to the extent anticipated by financial or industry analysts.
S-12

The market price of our common stock may be volatile, and you could lose all or part of your investment.

The trading price of our common stock is likely to be volatile. The stock market recently has experienced extreme volatility. This volatility often has been unrelated or disproportionate to the operating performance of particular companies. You may not be able to resell your shares of common stock at an attractive price due to a number of factors such as those listed in this Risk Factors section and the following:

results of operations that vary from the expectations of securities analysts and investors;
results of operations that vary from those of the Company's competitors;
changes in expectations as to the Company's future financial performance, including financial estimates and investment recommendations by securities analysts and investors;
declines in the market prices of stocks generally;
strategic actions by the Company or its competitors;
announcements by the Company or its competitors of significant contracts, acquisitions, joint ventures, other strategic relationships or capital commitments;
announcements of estimates by third parties of actual or anticipated changes in the size of the Company's customer base or the level of customer engagement;
any significant change in the Company's management;
changes in general economic or market conditions or trends in the Company's industry or markets;
changes in business or regulatory conditions, including new laws or regulations or new interpretations of existing laws or regulations applicable to the Company's business;
additional shares of the Company's securities being sold or issued into the market by the Company or any of the existing stockholders or the anticipation of such sales, including if the Company issues shares to satisfy restricted stock unit related tax obligations or if existing stockholders sell shares into the market when applicable "lock-up" periods end;
investor perceptions of the investment opportunity associated with the Company's common stock relative to other investment alternatives;
the public's response to press releases or other public announcements by the Company or third parties, including the Company's filings with the SEC;
litigation involving the Company, the Company's industry, or both, or investigations by regulators into the Company's operations or those of the Company's competitors;
guidance, if any, that the Company provides to the public, any changes in this guidance or the Company's failure to meet this guidance;
the development and sustainability of an active trading market for the Company's common stock;
actions by institutional or activist stockholders;
developments in new legislation and pending lawsuits or regulatory actions, including interim or final rulings by judicial or regulatory bodies;
changes in accounting standards, policies, guidelines, interpretations or principles; and
other events or factors, including those resulting from pandemics, natural disasters, war, acts of terrorism or responses to these events.

These broad market and industry fluctuations may adversely affect the market price of the Company's common stock, regardless of the Company's actual operating performance. In addition, price volatility may be greater if the public float and trading volume of the Company's common stock is low.

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If the Company was involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from our business regardless of the outcome of such litigation.

S-13

Because there are no current plans to pay cash dividends on the Company's common stock for the foreseeable future, you may not receive any return on investment unless you sell your shares of the Company's common stock at a price greater than what you paid for it.

The Company intends to retain future earnings, if any, for future operations, expansion and debt repayment, and there are no current plans to pay any cash dividends for the foreseeable future. The declaration, amount and payment of any future dividends on shares of the Company's common stock will be at the sole discretion of the Company's board of directors. The Company's board of directors may take into account general and economic conditions, the Company's financial condition and results of operations, the Company's available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions, implications of the payment of dividends by the Company to its stockholders or by its subsidiaries to it and such other factors as the Company's board of directors may deem relevant. As a result, you may not receive any return on an investment in the Company's common stock unless you sell your shares of the Company's common stock for a price greater than that which you paid for it.

The Company's stockholders may experience dilution in the future.

The percentage of shares of the Company's common stock owned by current stockholders may be diluted in the future because of equity issuances for acquisitions, capital market transactions or otherwise, including, without limitation, equity awards that the Company may grant to its directors, officers and employees, exercise of the Company's warrants. Such issuances may have a dilutive effect on the Company's earnings per share, which could adversely affect the market price of the Company's common stock.

If securities or industry analysts do not publish research or reports about the Company's business, if they change their recommendations regarding the Company's common stock or if the Company's operating results do not meet their expectations, the Company's common stock price and trading volume could decline.

The trading market for the Company's common stock will depend in part on the research and reports that securities or industry analysts publish about the Company or its businesses. If no securities or industry analysts commence coverage of the Company, the trading price for the Company's common stock could be negatively impacted. In the event securities or industry analysts initiate coverage, if one or more of the analysts who cover the Company downgrade its securities or publish unfavorable research about its businesses, or if the Company's operating results do not meet analyst expectations, the trading price of the Company's common stock would likely decline. If one or more of these analysts cease coverage of the Company or fail to publish reports on the Company regularly, demand for the Company's common stock could decrease, which might cause the Company's common stock price and trading volume to decline.

Future sales, or the perception of future sales, by the Company or its stockholders in the public market following the Business Combination could cause the market price for the Company's common stock to decline.

The sale of shares of the Company's common stock and/or public warrants in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of the Company's common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for the Company to sell equity securities in the future at a time and at a price that it deems appropriate.

As an emerging growth company within the meaning of the Securities Act, the Company is permitted to rely on certain exemptions from disclosure requirements available to emerging growth companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We qualify as an "emerging growth company" within the meaning of the Securities Act, as modified by the JOBS Act. We plan to continue to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, the company's stockholders may not have access to certain information they may deem important. We cannot predict whether investors will find securities issued by the Company less attractive because the Company will rely on these exemptions. If some investors find those securities less attractive as a result of its reliance on these exemptions, the trading prices of the Company's securities may be lower than they otherwise would be, there may be a less active trading market for the Company's securities and the trading prices of the Company's securities may be more volatile.

S-14

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make a comparison of the Company's financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

The Company will remain an emerging growth company until the earliest of: (i) the last day of the fiscal year following the fifth anniversary of the closing of the IPO, (ii) the last day of the fiscal year in which the Company has total annual gross revenue of at least $1.235 billion; (iii) the last day of the fiscal year in which the Company is deemed to be a "large accelerated filer" as defined in Rule 12b-2 under the Exchange Act, which would occur if the market value of the Company's common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year; or (iv) the date on which the Company has issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

Substantial future sales of shares of our common stock could cause the market price of our common stock to decline.

The market price of shares of our common stock could decline as a result of substantial sales of our common stock, particularly sales by our directors, executive officers and significant stockholders, a large number of shares of our common stock becoming available for sale or the perception in the market that holders of a large number of shares intend to sell their shares.

If we fail to maintain effective internal control over financial reporting, the price of our securities may be adversely affected.

Our internal control over financial reporting may have weaknesses and conditions that could require correction or remediation, the disclosure of which may have an adverse impact on the price of our common stock. We are required to establish and maintain appropriate internal control over financial reporting. Failure to establish those controls, or any failure of those controls once established, could adversely affect our public disclosures regarding our business, prospects, financial condition or results of operations. In addition, management's assessment of internal control over financial reporting may identify weaknesses and conditions that need to be addressed in our internal control over financial reporting or other matters that may raise concerns for investors. Any actual or perceived weaknesses and conditions that need to be addressed in our internal control over financial reporting or disclosure of management's assessment of our internal control over financial reporting may have an adverse impact on the price of our common stock.

As an emerging growth company, our auditor is not required to attest to the effectiveness of our internal controls.

Our independent registered public accounting firm is not required to attest to the effectiveness of our internal control over financial reporting while we are an emerging growth company. This means that the effectiveness of our financial operations may differ from our peer companies in that they may be required to obtain independent registered public accounting firm attestations as to the effectiveness of their internal controls over financial reporting and we are not. While our management will be required to attest to internal control over financial reporting and we will be required to detail changes to our internal controls on a quarterly basis, we cannot provide assurance that the independent registered public accounting firm's audit process in assessing the effectiveness of our internal controls over financial reporting, if obtained, would not find one or more material weaknesses or significant deficiencies. Further, once we cease to be an emerging growth company and cease to be a smaller reporting company (as described below), we will be subject to independent registered public accounting firm attestation regarding the effectiveness of our internal controls over financial reporting. Even if management finds such controls to be effective, our independent registered public accounting firm may decline to attest to the effectiveness of such internal controls and issue a qualified report.

S-15

Our common stock may be subject to the "penny stock" rules in the future. It may be more difficult to resell securities classified as "penny stock."

Our common stock may be subject to "penny stock" rules (generally defined as non-exchange traded stock with a per-share price below $5.00) in the future. While our common stock is not currently considered "penny stock" since it is listed on Nasdaq, if we are unable to maintain that listing and our common stock is no longer listed on Nasdaq, unless we maintain a per-share price above $5.00, our common stock will become "penny stock." These rules impose additional sales practice requirements on broker-dealers that recommend the purchase or sale of penny stocks to persons other than those who qualify as "established customers" or "accredited investors." For example, broker-dealers must determine the appropriateness for non-qualifying persons of investments in penny stocks. Broker-dealers must also provide, prior to a transaction in a penny stock not otherwise exempt from the rules, a standardized risk disclosure document that provides information about penny stocks and the risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, disclose the compensation of the broker-dealer and its salesperson in the transaction, furnish monthly account statements showing the market value of each penny stock held in the customer's account, provide a special written determination that the penny stock is a suitable investment for the purchaser, and receive the purchaser's written agreement to the transaction.

Legal remedies available to an investor in "penny stocks" may include the following:

If a "penny stock" is sold to the investor in violation of the requirements listed above, or other federal or states securities laws, the investor may be able to cancel the purchase and receive a refund of the investment.
If a "penny stock" is sold to the investor in a fraudulent manner, the investor may be able to sue the persons and firms that committed the fraud for damages.

These requirements may have the effect of reducing the level of trading activity, if any, in the secondary market for a security that becomes subject to the penny stock rules. The additional burdens imposed upon broker-dealers by such requirements may discourage broker-dealers from effecting transactions in our securities, which could severely limit the market price and liquidity of our securities. These requirements may restrict the ability of broker-dealers to sell our common stock and may affect your ability to resell our common stock.

Many brokerage firms will discourage or refrain from recommending investments in penny stocks. Most institutional investors will not invest in penny stocks. In addition, many individual investors will not invest in penny stocks due, among other reasons, to the increased financial risk generally associated with these investments.

For these reasons, penny stocks may have a limited market and, consequently, limited liquidity. We can give no assurance at what time, if ever, our common stock will not be classified as a "penny stock" in the future.

We believe we will be considered a smaller reporting company and will be exempt from certain disclosure requirements, which could make our common stock less attractive to potential investors.

Rule 12b-2 of the Exchange Act defines a "smaller reporting company" as an issuer that is not an investment company, an asset-backed issuer, or a majority-owned subsidiary of a parent that is not a smaller reporting company and that:

had a public float of less than $250 million as of the last business day of its most recently completed second fiscal quarter, computed by multiplying the aggregate worldwide number of shares of its voting and non-voting common equity held by non-affiliates by the price at which the common equity was last sold, or the average of the bid and asked prices of common equity, in the principal market for the common equity; or
in the case of an initial registration statement under the Securities Act or the Exchange Act for shares of its common equity, had a public float of less than $250 million as of a date within 30 days of the date of the filing of the registration statement, computed by multiplying the aggregate worldwide number of such shares held by non-affiliates before the registration plus, in the case of a Securities Act registration statement, the number of such shares included in the registration statement by the estimated public offering price of the shares; or
S-16
in the case of an issuer whose public float as calculated under paragraph (1) or (2) of this definition was zero or whose public float was less than $700 million, had annual revenues of less than $100 million during the most recently completed fiscal year for which audited financial statements are available.

As a smaller reporting company, we are not required to, and may not, include a Compensation Discussion and Analysis section in our proxy statements; we will provide only two years of financial statements; and we need not provide the table of selected financial data. We also will have other "scaled" disclosure requirements that are less comprehensive than issuers that are not smaller reporting companies which could make our common stock less attractive to potential investors, which could make it more difficult for our stockholders to sell their shares.

We incur significant costs as a result of operating as a public company, and our management is required to devote substantial time to new compliance initiatives.

As a public company, we incur significant legal, accounting and other expenses that we did not previously incur as a private company. In addition, the Sarbanes-Oxley Act has imposed various requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls. Our management and other personnel need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations have increased and will continue to increase our legal and financial compliance costs and will make some activities more time-consuming and costly. We cannot predict or estimate the amount of additional costs we will incur as a public company or the timing of such costs.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we must perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. In addition, we will be required to have our independent registered public accounting firm attest to the effectiveness of our internal control over financial reporting for Form 10-K or the first annual report on Form 10-K following the date on which we are no longer an emerging growth company or a non-accelerated filer. Our compliance with Section 404 of the Sarbanes-Oxley Act will require that we incur substantial expense and expend significant management efforts. We currently do not have an internal audit group, and we will need to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge. If we are not able to comply with the requirements of Section 404 in a timely manner, or if we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the value of our securities could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources.

Our ability to successfully implement our business plan and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. We expect that we will need to continue to improve existing, and implement new operational and financial systems, procedures and controls to manage our business effectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations to suffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls from our auditors as required under Section 404 of the Sarbanes-Oxley Act. This, in turn, could have an adverse impact on value of our securities, and could adversely affect our ability to access the capital markets.

Delaware law and the Company certificate of incorporation and bylaws contain certain provisions, including anti-takeover provisions, that limit the ability of stockholders to take certain actions and could delay or discourage takeover attempts that stockholders may consider favorable.

The Amended Charter and the Company's bylaws and the DGCL, contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by the Company's board of directors and therefore depress the trading price of the Company's common stock. These provisions could also make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the Company's board of directors or taking other corporate actions, including effecting changes in the management of the Company. Among other things, the Amended Charter and the Company's bylaws include provisions regarding:

the ability of the Company's board of directors to issue shares of one or more series of preferred stock, out of the Company's "blank check" preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;
a board of directors consisting of one class of directors, with directors generally elected for one-year terms;
S-17
the limitation of the liability of, and the indemnification of, the Company's directors and officers;
the fact that the total number of directors constituting the Company's board of directors (other than directors elected by the holders of one or more series of our preferred stock voting separately as a class or series) may be fixed exclusively by our board of directors and the fact that vacancies and newly created directorships on the Company's board of directors may be filled solely and exclusively by a majority of the directors, which prevents stockholders from being able to fill vacancies and newly created directorships on the Company's board of directors;
limitations on stockholder action by written consent, including that certain actions may be taken by written consent only if approved by a majority of our directors and subject to applicable law;
restriction on stockholder action by written consent (except where the action is approved by a majority of our directors), which, absent the approval of a majority of our directors, requires stockholder action to be taken at an annual or special meeting of stockholders and could delay the ability of stockholders to force consideration of a stockholder proposal or to take action, including the removal of directors, outside of an annual or special meeting of stockholders;
the procedures for the conduct and scheduling of board of directors and stockholder meetings;
the ability of the Company's board of directors to amend the bylaws, which may allow the Company's board of directors to take additional actions to prevent an unsolicited takeover and inhibit the ability of an acquirer to amend the bylaws to facilitate an unsolicited takeover attempt; and
advance notice procedures with which stockholders must comply to nominate candidates to the Company's board of directors or to propose matters to be acted upon at a stockholders' meeting, which could preclude stockholders from bringing matters before annual or special meetings of stockholders and delay changes in the Company's board of directors and also may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer's own slate of directors or otherwise attempting to obtain control of the Company.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in the Company's board of directors or management.

Any provision of the Amended Charter, the Company's bylaws or Delaware law that has the effect of delaying or preventing a change in control could limit the opportunity for stockholders to receive a premium for their shares of the Company's capital stock and could also affect the price that some investors are willing to pay for the Company's common stock.

S-18

The Amended Charter designates a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between the Company and its stockholders, and also provides that the federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, each of which could limit the ability of the Company's stockholders to choose the judicial forum for disputes with the Company or its directors, officers, or employees.

The Amended Charter provides that, unless the Company consents in writing to the selection of an alternative forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on its behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of its directors, officers, or other employees to the Company or its stockholders, (iii) any action arising pursuant to any provision of the DGCL, or the certificate of incorporation or the bylaws or (iv) any other action asserting a claim that is governed by the internal affairs doctrine shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware), in all cases subject to the court having jurisdiction over indispensable parties named as defendants. The Amended Charter also provides that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. The exclusive forum provision will be applicable to the fullest extent permitted by applicable law, subject to certain exceptions. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. We note, however, that there is uncertainty as to whether a court would enforce this provision and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Section 22 of the Securities Act creates concurrent jurisdiction for state and federal courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

Any person or entity purchasing or otherwise acquiring any interest in any of the Company's securities shall be deemed to have notice of and consented to this provision. This exclusive-forum provision may limit a stockholder's ability to bring a claim in a judicial forum of its choosing for disputes with the Company or its directors, officers, or other employees, which may discourage lawsuits against the Company and its directors, officers, and other employees. If a court were to find the exclusive-forum provision to be inapplicable or unenforceable in an action, the Company may incur additional costs associated with resolving the dispute in other jurisdictions, which could harm its results of operations.

Anti-takeover effects of certain provisions of Delaware state law could hinder a potential takeover of the Company.

The Company is subject to provisions of Section 203 of the DGCL, which is Delaware's anti-takeover law. In general, Section 203 of the DGCL restricts certain "business combinations" (which generally includes mergers, asset sales and other transactions) with an "interested stockholder" (which is defined generally as a person that, together with the person's affiliates and associates, owns 15% or more of the Company's outstanding voting stock ) for a period of three years following the date a person became an interested stockholder, unless prior approval of our board of directors is obtained or as otherwise provided. These anti-takeover provisions and other provisions in the Company's Amended Charter and amended and restated bylaws could make it more difficult for stockholders or potential acquirers to obtain control of the Company's board of directors or initiate actions that are opposed by the then-current board of directors and could also delay or impede a merger, tender offer or proxy contest involving the Company. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing or cause the Company to take other corporate actions you desire. Any delay or prevention of a change of control transaction or changes in the Company's board of directors could cause the market price of the Company's common stock to decline.

Certain provisions of the Company's bylaws are intended to strengthen the position of the Company's board of directors in the event of a hostile takeover attempt. These provisions have the effect of providing the Company's board of directors with the sole power to fix the total number of directors constituting the board of directors, to fill vacancies and newly created directorships on the Company's board of directors, restricting stockholders' ability to act by written consent in lieu of a meeting, and prohibiting stockholders from calling special meetings. The Company may include provisions in its certificate of incorporation that may discourage a third party from making a proposal to acquire us, even if some of its stockholders might consider the proposal to be in their best interests. For example, the Company may amend its certificate of incorporation to authorize its board of directors to issue one (1) or more classes or series of preferred stock that could discourage or delay a tender offer or change in control. In addition, the Company may enter into a stockholder rights plan, commonly known as a "poison pill," that may delay or prevent a change of control.

Provisions in the Amended Charter and Delaware law may have the effect of discouraging lawsuits against the Company and its directors and officers.

The Amended Charter provides that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on its behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of its directors, officers, or other employees to the Company or its stockholders, (iii) any action asserting a claim against the Company, its directors, officers or employees arising pursuant to any provision of the DGCL, or the certificate of incorporation or the bylaws or (iv) any other action asserting a claim against the Company, its directors, officers or employees that is governed by the internal affairs doctrine shall be the Court of Chancery of the State of Delaware, except (with respect to the foregoing items (i) through (iv)) any claim (a) as to which the Court of Chancery of the State of Delaware determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery of the State of Delaware (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery of the State of Delaware within ten days following such determination), (b) that is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery of the State of Delaware, or (c) for which the Court of Chancery of the State of Delaware does not have subject matter jurisdiction, as to which the Court of Chancery and the U.S. federal district court for the District of Delaware shall have concurrent jurisdiction. The Amended Charter also provides that, unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. The exclusive forum provision will be applicable to the fullest extent permitted by applicable law, subject to certain exceptions. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. We note, however, that there is uncertainty as to whether a court would enforce this provision and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Section 22 of the Securities Act creates concurrent jurisdiction for state and federal courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

Any person or entity purchasing or otherwise acquiring any interest in any of the Company's securities shall be deemed to have notice of and consented to this provision. This exclusive-forum provision may limit a stockholder's ability to bring a claim in a judicial forum of its choosing for disputes with the Company or its directors, officers, or employees, which may discourage lawsuits against the Company and its directors, officers, and employees. If a court were to find the exclusive-forum provision to be inapplicable or unenforceable in an action, the Company may incur additional costs associated with resolving the dispute in other jurisdictions, which could harm its results of operations.

S-19

The Company's bylaws further provide that, unless the Company consents in writing to an alternative forum, the United States District Court for the District of Delaware will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. The Company's bylaws also provide that any person or entity purchasing or otherwise acquiring any interest in shares of the Company's capital stock will be deemed to have notice of and to have consented to this choice of forum provision. The Company recognizes that the forum selection clause in the Company's bylaws may impose additional litigation costs on stockholders in pursuing any such claims, particularly if the stockholders do not reside in or near the State of Delaware. Additionally, the forum selection clause in the Company's bylaws may limit the Company's stockholders' ability to bring a claim in a forum that they find favorable for disputes with us or the Company's directors, officers or employees, which may discourage such lawsuits against us and the Company's directors, officers and employees even though an action, if successful, might benefit the Company's stockholders. If a court were to find these exclusive-forum provisions in the Company's certificate of incorporation or bylaws to be inapplicable or unenforceable in an action, the Company may incur additional costs associated with resolving the dispute in other jurisdictions, which could seriously harm the Company's business. Nothing in the Company's certificate of incorporation or bylaws will preclude stockholders that assert claims under the Securities Act or the Exchange Act from bringing such claims in state or federal court, subject to applicable law.

The Company is a "controlled company" within the meaning of the applicable rules of Nasdaq and, as a result, we qualify for exemptions from certain corporate governance requirements. If the Company relies on these exemptions, its stockholders will not have the same protections afforded to stockholders of companies that are subject to such requirements.

As of April 16, 2026, Dr. Aikawa and entities he controls collectively control approximately 85.2% of the voting power of our outstanding common stock. After this offering, Dr. Aikawa and entities he controls would collectively control approximately % (or %, if the underwriters fully exercise their option to purchase additional shares) of the voting power of our outstanding common stock. Accordingly, the Company is, and following this offering will continue to be, a "controlled company" within the meaning of applicable rules of Nasdaq. 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" and may elect not to comply with certain corporate governance requirements, including the requirements:

that a majority of the board consists of independent directors;
for an annual performance evaluation of the nominating and corporate governance and compensation committees;
that the controlled company has 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 the controlled company has a compensation committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibility.

While the Company does not intend to rely on these exemptions, the Company may use these exemptions now or in the future. As a result, the Company's stockholders may not have the same protections afforded to stockholders of companies that are subject to all of the Nasdaq corporate governance requirements.

If the voting power of our capital stock continues to be highly concentrated, it may prevent you and other minority shareholders from influencing significant corporate decisions and may result in conflicts of interest.

As of April 16, 2026, Dr. Aikawa and entities he controls collectively control approximately 85.2 % of the voting power of our outstanding common stock. After this offering, Dr. Aikawa and entities he controls would collectively control approximately % (or %, if the underwriters fully exercise their option to purchase additional shares) of the voting power of our outstanding common stock. As a result, Dr. Aikawa has, and after the completion of this offering, will continue to have, majority voting power over all matters requiring shareholder votes, including: the election of directors; mergers, consolidations and acquisitions; the sale of all or substantially all of our assets and other decisions affecting our capital structure; amendments to our certificate of incorporation or our bylaws; and our winding up and dissolution.

This concentration of voting power may delay, deter or prevent acts that would be favored by our other stockholders. The interests of Dr. Aikawa may not always coincide with our interests or the interests of our other stockholders. This concentration of voting power may also have the effect of delaying, preventing or deterring a change in control of us. Also, Dr. Aikawa may seek to cause us to take courses of action that, in his judgment, could enhance his investment in us, but which might involve risks to our other stockholders or adversely affect us or our other stockholders. As a result, the market price of our shares of common stock could decline or stockholders might not receive a premium over then-current market price of our shares of common stock upon a change in control. In addition, this concentration of voting power may adversely affect the trading price of our shares of common stock.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following is a summary of certain United States federal income tax consequences of the ownership and disposition of our common stock. This summary deals only with common stock that is held as a capital asset by a non-U.S. holder (as defined below).

A "non-U.S. holder" means a beneficial owner of our common stock (other than an entity or arrangement treated as a partnership for United States federal income tax purposes) that is not, for United States federal income tax purposes, any of the following:

an individual who is a citizen or resident of the United States;
a corporation (or any other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;
an estate the income of which is subject to United States federal income taxation regardless of its source; or
a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended (the "Code"), and regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income tax consequences different from those summarized below. This summary does not address all of the United States federal income tax consequences that may be relevant to you in light of your particular circumstances, nor does it address the Medicare tax on net investment income, United States federal estate and gift taxes or the effects of any state, local or non-United States tax laws. In addition, it does not represent a detailed description of the United States federal income tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws (including if you are a United States expatriate, foreign pension fund, "controlled foreign corporation," "passive foreign investment company" or a partnership or other pass-through entity for United States federal income tax purposes). We cannot assure you that a change in law will not alter significantly the tax considerations that we describe in this summary.

If a partnership (or other entity or arrangement treated as a partnership for United States federal income tax purposes) holds our common stock, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner of a partnership considering an investment in our common stock, you should consult your tax advisors.

If you are considering the purchase of our common stock, you should consult your own tax advisors concerning the particular United States federal income tax consequences to you of the ownership and disposition of our common stock, as well as the consequences to you arising under other United States federal tax laws and the laws of any other taxing jurisdiction.

Dividends

In the event that we make a distribution of cash or other property (other than certain pro rata distributions of our stock) in respect of our common stock, the distribution generally will be treated as a dividend for United States federal income tax purposes to the extent it is paid from our current or accumulated earnings and profits, as determined under United States federal income tax principles. Any portion of a distribution that exceeds our current and accumulated earnings and profits generally will be treated first as a tax-free return of capital, causing a reduction in the adjusted tax basis of a non-U.S. holder's common stock, and to the extent the amount of the distribution exceeds a non-U.S. holder's adjusted tax basis in our common stock, the excess will be treated as gain from the disposition of our common stock (the tax treatment of which is discussed below under "- Gain on Disposition of Common Stock").

Dividends paid to a non-U.S. holder generally will be subject to withholding of United States federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. However, dividends that are effectively connected with the conduct of a trade or business by the non-U.S. holder within the United States (and, if required by an applicable income tax treaty, are attributable to a United States permanent establishment) are not subject to the withholding tax, provided certain certification and disclosure requirements are satisfied (generally, by providing the applicable withholding agent with a properly executed Internal Revenue Service ("IRS") Form W-8ECI certifying that the dividends are effectively connected with such holder's conduct of a trade or business in the United States and are includible in such holder's gross income). Instead, such dividends are subject to United States federal income tax on a net income basis generally in the same manner as if the non-U.S. holder were a United States person as defined under the Code. Any such effectively connected dividends received by a foreign corporation may be subject to an additional "branch profits tax" at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

S-23

A non-U.S. holder who wishes to claim the benefit of an applicable treaty rate and avoid backup withholding, as discussed below, for dividends will be required (a) to provide the applicable withholding agent with a properly executed IRS Form W-8BEN or Form W-8BEN-E (or other applicable form) certifying under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (b) if our common stock is held through certain foreign intermediaries, to satisfy the relevant certification requirements of applicable United States Treasury regulations. Special certification and other requirements apply to certain non-U.S. holders that are pass-through entities rather than corporations or individuals.

A non-U.S. holder eligible for a reduced rate of United States federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Gain on Disposition of Common Stock

Subject to the discussion of backup withholding below, any gain realized by a non-U.S. holder on the sale or other disposition of our common stock generally will not be subject to United States federal income tax unless:

the gain is effectively connected with a trade or business of the non-U.S. holder within the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment of the non-U.S. holder);
the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met; or
we are or have been a "United States real property holding corporation" for United States federal income tax purposes and certain other conditions are met.

A non-U.S. holder described in the first bullet point immediately above will be subject to tax on the gain derived from the sale or other disposition in the same manner as if the non-U.S. holder were a United States person as defined under the Code. In addition, if any non-U.S. holder described in the first bullet point immediately above is a foreign corporation, the gain realized by such non-U.S. holder may be subject to an additional "branch profits tax" at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. An individual non-U.S. holder described in the second bullet point immediately above will be subject to a 30% (or such lower rate as may be specified by an applicable income tax treaty) tax on the gain derived from the sale or other disposition, which gain may be offset by United States source capital losses even though the individual is not considered a resident of the United States.

Generally, a corporation is a "United States real property holding corporation" if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business (all as determined for United States federal income tax purposes). We believe we are not and do not anticipate becoming a "United States real property holding corporation" for United States federal income tax purposes.

Information Reporting and Backup Withholding

Distributions paid to a non-U.S. holder and the amount of any tax withheld with respect to such distributions generally will be reported to the IRS. Copies of the information returns reporting such distributions and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty.

A non-U.S. holder will not be subject to backup withholding on distributions received if such holder certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that such holder is a United States person as defined under the Code), or such holder otherwise establishes an exemption.

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale or other disposition of our common stock within the United States or conducted through certain United States-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person as defined under the Code), or such owner otherwise establishes an exemption.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a non-U.S. holder's United States federal income tax liability provided the required information is timely furnished to the IRS.

Additional Withholding Requirements

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as "FATCA"), a 30% United States federal withholding tax may apply to any dividends paid on our common stock to (i) a "foreign financial institution" (as specifically defined in the Code and whether such foreign financial institution is the beneficial owner or an intermediary) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner which avoids withholding, or (ii) a "non-financial foreign entity" (as specifically defined in the Code and whether such non-financial foreign entity is the beneficial owner or an intermediary) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) adequate information regarding certain substantial United States beneficial owners of such entity (if any). If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under "- Dividends," an applicable withholding agent may credit the withholding under FATCA against, and therefore reduce, such other withholding tax. While withholding under FATCA would also have applied to payments of gross proceeds from the sale or other taxable disposition of our common stock, proposed United States Treasury regulations (upon which taxpayers may rely until final regulations are issued) eliminate FATCA withholding on payments of gross proceeds entirely. You should consult your own tax advisors regarding these requirements and whether they may be relevant to your ownership and disposition of our common stock.

S-24

DIVIDEND POLICY

We have not paid any cash dividends on our common stock and do not currently anticipate paying cash dividends in the foreseeable future. The agreements into which we may enter in the future, including indebtedness, may impose limitations on our ability to pay dividends or make other distributions on our capital stock. Payment of future dividends on our common stock, if any, will be at the discretion of our board of directors and will depend on, among other things, our results of operations, cash requirements and surplus, financial condition, contractual restrictions and other factors that our board of directors may deem relevant. We intend to retain future earnings, if any, for reinvestment in the development and expansion of our business. See "Risk Factors-Risks Related to the Offering and Ownership of Our Common Stock-Because there are no current plans to pay cash dividends on the Company's common stock for the foreseeable future, you may not receive any return on investment unless you sell your shares of the Company's common stock at a price greater than what you paid for it."

For a discussion of the application of withholding taxes on dividends, see "Material U.S. Federal Income Tax Consequences for Non-U.S. Holders."

Listing

Our common stock is listed on Nasdaq under the symbol "SBC."

Price Stabilization, Short Positions and Penalty Bids

Until the distribution of the shares is completed, SEC rules may limit the underwriters and selling group members from bidding for and purchasing our common stock. However, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriters may over-allot or otherwise create a short position in our common stock for their own account by selling more common stock than we have sold to the underwriters. The underwriters may close out any short position by either exercising their option to purchase additional shares or purchasing shares in the open market.

In addition, the underwriters may stabilize or maintain the price of our common stock by bidding for or purchasing shares in the open market and may impose penalty bids. If penalty bids are imposed, selling concessions allowed to broker-dealers participating in this offering are reclaimed if shares previously distributed in this offering are repurchased, whether in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of our common stock at a level above that which might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of our common stock to the extent that it discourages resales of our common stock. The magnitude or effect of any stabilization or other transactions is uncertain. These transactions may be effected on the Nasdaq or otherwise and, if commenced, may be discontinued at any time.

In connection with this offering, the underwriters may also engage in passive market making transactions in our common stock on the Nasdaq. Passive market making consists of displaying bids on the Nasdaq at the prices of independent market makers and effecting purchases limited by those prices in response to order flow. Rule 103 of Regulation M promulgated by the SEC limits the amount of net purchases that each passive market maker may make and the displayed size of each bid. Passive market making may stabilize the market price of our common stock at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

S-27

None of us, the selling stockholder or the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, none of us, the selling stockholder or the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Electronic Distribution

In connection with the offering, the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail. A prospectus in electronic format may be made available on the websites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make internet distributions on the same basis as other allocations.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financial and brokerage activities. The underwriters and its affiliates have provided, and may in the future provide, a variety of these services to the issuer and to persons and entities with relationships with the issuer, for which it received or will receive customary fees and expenses.

In addition, in the ordinary course of their business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

THE COMPANY

Company Overview

History

We were originally incorporated in Delaware on February 12, 2021 under the name "Pono Capital Two, Inc.," referred to herein as "Pono," as a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses.

On August 9, 2022, Pono consummated its IPO of 11,500,000 units (the "Units" and, with respect to the Class A common stock included in the Units being offered, the "Public Shares" and with respect to the warrants included in the Units, the "Public Warrants") (the "Pono IPO").

Simultaneously with the consummation of the closing of the Pono IPO, Pono consummated the private placement of an aggregate of 634,375 units (the "Placement Units") at a price of $10.00 per Placement Unit in a private placement to the Sponsor (the "Private Placement").

On September 26, 2022, the Class A common stock and Public Warrant included in the Units began separate trading on The Nasdaq Global Market under the symbols "PTWO" and "PTWOW," respectively.

On January 31, 2023, Pono entered into an Agreement and Plan of Merger (as subsequently amended from time to time, the "Merger Agreement") with Pono Two Merger Sub, Inc., a Delaware corporation ("Merger Sub") and then a wholly-owned subsidiary of Pono, SBC Medical Group, Inc., then named SBC Medical Group Holdings Incorporated, a Delaware corporation ("Legacy SBC"), Mehana Capital LLC, a Delaware limited liability company ("Sponsor" or "Purchaser Representative") in its capacity as the representative of the stockholders of Pono, and Yoshiyuki Aikawa in his personal capacity and his capacity as the representative of the stockholders of Legacy SBC ("Seller Representative").

On September 17, 2024, the closing (the "Closing") of the merger (the "Merger") and other transactions contemplated thereby (collectively, the "Business Combination") took place and the Merger was consummated with Merger Sub merging with and into Legacy SBC with Legacy SBC surviving the Merger as a wholly-owned subsidiary of Pono, and Pono then changed its name to SBC Medical Group Holdings Incorporated and on September 17, 2024, Legacy SBC changed its named to SBC Medical Group, Inc.

Effective September 17, 2024, Pono's units ceased trading, and effective September 18, 2024, SBC's common stock began trading on the Nasdaq Global Market under the symbol "SBC" and the public warrants began trading on the Nasdaq Capital Market under the symbol "SBCWW."

As a result of the Closing of the Merger and the Business Combination, the business of SBC Medical Group, Inc. ("Legacy SBC"), became the business of the Company.

Business Overview

The Company is a management company headquartered in Irvine California and Tokyo, Japan, that owns, operates, and provides management services to cosmetic treatment centers mainly in Japan, with footprint also in Vietnam, Singapore and the United States. The history of Legacy SBC began with the establishment of L'Ange Cosmetique Co., Ltd. in 2003 and SBCMG (formerly Aikawa Medical) in 2017 for the purpose of providing management services to medical corporations and the medical clinics of the medical corporations. The history of the medical corporations and the medical clinics began in 2000 with the opening of Shonan Beauty Clinic in Fujisawa City, Japan, where Dr. Aikawa opened in private practice. Subsequently, Dr. Aikawa opened clinics in Yokohama in 2001 and Shinjuku in 2003, incorporated as Medical Corporation Shobikai in 2004, acquired a medical corporation named Medical Corporation Kowakai in 2009 and Medical Corporation Nasukai in 2009.

The Company and its subsidiaries are primarily focused on providing comprehensive management services to franchisee clinics, including but not limited to advertising and marketing needs across various platforms (such as social media networks), staff management (such as recruitment and training), booking reservations for franchisee clinic customers, assistance with franchisee employee housing rentals and facility rentals, construction and design of franchisee clinics, medical equipment and medical consumables procurement (resale), the provision of cosmetic products to franchisee clinics for resale to clinic customers, licensure of the use of patent-pending and non-patented medical technologies, trademark and brand use, IT software solutions (including but not limited to remote medical consultations), management of the franchisee clinic's customer rewards program (customer loyalty point program), and payment tools for the franchisee clinics.

Our wholly owned subsidiary, SBC Medical Group Co., Ltd., a Japan corporation ("SBC Medical Sub", or "SBC Japan") is designated as a "medical service corporation" in Japan. In Japan, a medical service corporation is a legal entity that provides management service to "medical corporations". The management services are conducted through franchisor-franchisee contracts and/or service contracts between SBC Medical Sub and the medical corporations that own all 258 of the treatment centers in Japan as of September 30, 2025. These clinics provide include but are not limited to breast augmentation, liposuction, rejuvenation treatments (including treatment of wrinkles, acne, scars, cellulite, excess fat, discoloration, and signs of aging), laser skin toning and spot removal, eyes double fold surgery, rhinoplasty, treatment of osmidrosis and hyperhidrosis, hair transplants, gynecological formation treatments, laser hair removal, face line surgeries, cosmetical dental procedures, tattoo removal, lasik eye surgery, lateral canthoplasty, brow lift procedures, androgenetic alopecia treatment, and cheek sagging prevention methods. In addition, similar management services are provided to four independently operated clinics.

The Company's subsidiaries have entered into franchisor-franchisee contracts and service contracts with six medical corporations, consisting of Medical Corporation Shobikai, Medical Corporation Kowakai, Medical Corporation Nasukai, Medical Corporation Aikeikai, Medical Corporation Jukeikai and Medical Corporation Ritz Cosmetic Surgery. In addition, the Company has entered into service contracts since September 2023 with Medical Corporation Association Furinkai and Medical Corporation Association Junikai; and in July 2025 with Medical Corporation Misakikai and General Incorporated Association Miotokai, following the acquisition of MB Career Lounge Co., Ltd. (collectively with the six franchisee medical corporations, the "Medical Corporations and/or General Incorporated Associations" or "MCs"). All of the Medical Corporations and General Incorporated Associations are deemed to be related parties of the Company since relatives of the CEO of the Company are the members* of general meetings of members** of the Medical Corporations or General Incorporated Associations. The CEO of the Company was previously a member* of the six franchisee Medical Corporations until he ceased being a member* in July 2023. The Company, through SBC Medical Sub, owns equity interests*** of the six franchisee medical corporations. Although the Company, through SBC Medical Sub, has an equity interest*** to the rights to receive a distribution of residual assets in proportion to the amount of contribution in certain circumstances as provided in the Japanese Medical Care Act and in the articles of incorporation (except Medical Corporation Association Furinkai, Medical Corporation Association Junikai, Medical Corporation Misakikai and General Incorporated Association Miotokai), the Company or SBC Medical Sub does not have voting control over the corporate actions at general meetings of members** of the Medical Corporations or General Incorporated Associations per the requirements of the Japanese Medical Care Act.

* "Members (or shain) of general meeting of members (or shain)" means one of the organs of a Japanese Medical Corporation, and element of general meeting of members (as explained below) of the Medical Corporation. Each member (or shain) of general meeting of members (or shain) has one voting right.

** "General meeting of members (or shain)" means one of the organs of a Japanese Medical Corporation, and the highest decision-making body of the Medical Corporation, of which the main duties include the election and dismissal of directors (or riji) and corporate auditors (or kanji) of the Medical Corporation, and the approval of financial statements and statutory business reports of the Medical Corporation.

*** "Equity interest (or mochibun)" means the right to receive distribution of the residual assets of a Japanese Medical Corporation in proportion to the amount of contribution (Article 10.3.3.2 brackets of the Supplementary Provision of the Japanese Medical Care Act.). However, the procedures for an equity interest (or mochibun) holder to exercise and realize the right to receive distribution of the residual assets of the Medical Corporation is more complicated than that of a stock corporation due to the restrictions under the Medical Care Act.

Implications of Being a Controlled Company

The Company is a "controlled company" within the meaning of the applicable rules of Nasdaq and, as a result, we qualify for exemptions from certain corporate governance requirements. If the Company relies on these exemptions, its stockholders will not have the same protections afforded to stockholders of companies that are subject to such requirements. As of December 23, 2025, Dr. Yoshiyuki Aikawa controlled approximately 90.36% of the voting power of our outstanding common stock, and, therefore controls a majority of the voting power of the Company's outstanding common stock, and the Company is a "controlled company" within the meaning of applicable rules of Nasdaq. 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" and may elect not to comply with certain corporate governance requirements, including the requirements:

that a majority of the board consists of independent directors;
for an annual performance evaluation of the nominating and corporate governance and compensation committees;
that the controlled company has 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 the controlled company has a compensation committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibility.

While the Company does not intend to rely on these exemptions, the Company may use these exemptions now or in the future. As a result, the Company's stockholders may not have the same protections afforded to stockholders of companies that are subject to all of the Nasdaq corporate governance requirements.

RISK FACTORS

Before you invest in any of our securities, in addition to the other information in this prospectus and any applicable prospectus supplement or free writing prospectus, you should carefully read and consider the risk factors under the heading "Risk Factors" contained in Part I, Item 1A in our most recent Annual Report on Form 10-K as well as any risk factors contained in our subsequent Quarterly Reports on Form 10-Q, which are incorporated by reference into this prospectus and any applicable prospectus supplement, as the same may be updated from time to time by our future filings under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Each of the risks described in these documents could materially and adversely affect our business, financial condition, liquidity, results of operations and prospects, and could result in a partial or complete loss of your investment.

USE OF PROCEEDS

Unless otherwise indicated in any applicable prospectus supplement, we intend to use the net proceeds we receive from the offering of securities under this prospectus for general corporate purposes. The net proceeds may be invested temporarily in short-term securities until they are used for their stated purpose. Further details relating to the use of net proceeds we receive from the offering of securities under this prospectus will be set forth in any applicable prospectus supplement.

We will not receive any of the proceeds from the sale of securities to which this prospectus relates that are offered by the selling securityholders.

We will receive up to an aggregate of approximately $139,545,312 from the exercise of Warrants, assuming the exercise in full of all of the Warrants for cash of $11.50 per share. We expect to use the net proceeds from the exercise of the Warrants for general corporate purposes.

DESCRIPTION OF SECURITIES

The following summary of the registered securities of SBC Medical Group Holdings Incorporated does not purport to be complete and is qualified in its entirety by reference to our certificate of incorporation, as amended and bylaws, as amended, each of which are included as an exhibit to the registration statement related to this prospectus and certain provisions of Delaware law. Unless the context requires otherwise, all references to the "Company," "we," "our," and "us" in this Exhibit refer to SBC Medical Group Holdings Incorporated.

Authorized Capital Stock

Our authorized capital stock consists of 400,000,000 shares of common stock, $0.0001 par value, and 20,000,000 shares of undesignated preferred stock, $0.0001 par value. The number of shares of registrant's Common Stock outstanding as of December 23, 2025 was 102,576,943 (excluding 270,000 shares held by a wholly owned subsidiary).

Common Stock

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Unless specified in the Amended Charter or bylaws, or as required by applicable provisions of the DGCL or applicable stock exchange rules, the affirmative vote of a majority of our shares of our common stock that are voted is required to approve any such matter voted on by our stockholders. Our board of directors consists of one class of directors, with each director elected for a one year term. There is no cumulative voting with respect to the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all of the directors. Our stockholders are entitled to receive ratable dividends when, as and if declared by the board of directors out of funds legally available therefor.

No shareholders of the Company holding common stock have any preemptive or other right to subscribe for any additional unissued or treasury shares of stock or for other securities of any class, or for rights, warrants or options to purchase stock, or for scrip, or for securities of any kind convertible into stock or carrying stock purchase warrants or privileges unless so authorized by the Company.

Preferred Stock

The Amended Charter provides that shares of preferred stock may be issued from time to time in one or more series. Our board of directors is authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. Our board of directors will be able to, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the common stock and could have anti-takeover effects. The ability of our board of directors to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no preferred stock outstanding at the date hereof. Although we do not currently intend to issue any shares of preferred stock, we cannot assure you that we will not do so in the future.

Warrants

Public Warrants

Each Public Warrant entitles the registered holder to purchase one share of our common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the closing of the Business Combination. The Public Warrants will expire five years after the Closing of the Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

We will not be obligated to deliver any shares of our common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the shares of our common stock underlying the warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described below with respect to registration. No warrant will be exercisable and we will not be obligated to issue shares of our common stock upon exercise of a warrant unless the Company's common stock issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Public Warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will we be required to net cash settle any warrant.

If a registration statement covering the shares of our common stock issuable upon exercise of the warrants is not effective, warrant holders may during any period when we will have failed to maintain an effective registration statement, exercise warrants on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act or another exemption. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis.

Once the Public Warrants become exercisable, we may call the warrants for redemption:

in whole and not in part;
at a price of $0.01 per warrant;
upon not less than 30 days' prior written notice of redemption to each warrant holder; and
if, and only if, the reported last sale price of our common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending three business days before we send the notice of redemption to the warrant holders.

To date, the shares of common stock have not traded at a price that would allow us to call the Public Warrants for redemption. If and when the Public Warrants become redeemable by us, we may not exercise our redemption right if the issuance of shares of common stock upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or we are unable to effect such registration or qualification. In the event that the Company elects to redeem all of the redeemable warrants as described above, the Company will fix a date for the redemption (the "Redemption Date"). Pursuant to the terms of the warrant agreement, notice of redemption will be mailed by first class mail, postage prepaid, by the Company not less than 30 days prior to the Redemption Date to the registered holders of the redeemable warrants to be redeemed at their last addresses as they appear on the registration books. In addition, the Company will issue a press release and file a current report on Form 8-K with the SEC containing notice of redemption. The Company is not contractually obligated to notify investors when its warrants become eligible for redemption and does not intend to so notify investors upon eligibility of the warrants for redemption, unless and until it elects to redeem such warrants pursuant to the terms of the warrant agreement.

9

We have established the last of the redemption criteria discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the Public Warrants, each warrant holder will be entitled to exercise its warrant prior to the scheduled redemption date. However, the price of our common stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) as well as the $11.50 warrant exercise price after the redemption notice is issued.

If we call the Public Warrants for redemption as described above, our management will have the option to require any holder that wishes to exercise its warrant to do so on a "cashless basis." In determining whether to require all holders to exercise their warrants on a "cashless basis," our management will consider, among other factors, our cash position, the number of warrants that are outstanding and the dilutive effect on our stockholders of issuing the maximum number of shares of our common stock issuable upon the exercise of our warrants. If our management takes advantage of this option, all holders of Public Warrants would pay the exercise price by surrendering their warrants for that number of shares of our common stock equal to the quotient obtained by dividing (x) the product of the number of shares of our common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the "fair market value" (defined below) by (y) the fair market value. The "fair market value" shall mean the average reported last sale price of our common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. If our management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of our common stock to be received upon exercise of the Public Warrants, including the "fair market value" in such case. Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption. We believe this feature is an attractive option to us if we do not need the cash from the exercise of the warrants after the Closing. If we call our Public Warrants for redemption and our management does not take advantage of this option, the Sponsor and its permitted transferees would still be entitled to exercise their Placement Warrants for cash or on a cashless basis using the same formula described above that other warrant holders would have been required to use had all warrant holders been required to exercise their warrants on a cashless basis, as described in more detail below.

A holder of a Public Warrant may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such warrant, to the extent that after giving effect to such exercise, such person (together with such person's affiliates), to the warrant agent's actual knowledge, would beneficially own in excess of 4.9% or 9.8% (or such other amount as a holder may specify) of the shares of our common stock outstanding immediately after giving effect to such exercise.

If the number of outstanding shares of our common stock is increased by a stock dividend payable in shares of our common stock, or by a split-up of shares of our common stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of our common stock issuable on exercise of each Public Warrant will be increased in proportion to such increase in the outstanding shares of our common stock. A rights offering to holders of our common stock entitling holders to purchase shares of our common stock at a price less than the fair market value will be deemed a stock dividend of a number of shares of our common stock equal to the product of (i) the number of shares of our common stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for our common stock) and (ii) one (1) minus the quotient of (x) the price per share of our common stock paid in such rights offering divided by (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for our common stock, in determining the price payable for our common stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) fair market value means the volume weighted average price of our common stock as reported during the ten (10) trading day period ending on the trading day prior to the first date on which the shares of our common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

10

In addition, if we, at any time while the Public Warrants are outstanding and unexpired, pay a dividend or make a distribution in cash, securities or other assets to the holders of our common stock on account of such shares of our common stock (or other shares of our capital stock into which the warrants are convertible), other than (a) as described above, (b) certain ordinary cash dividends, (c) to satisfy the redemption rights of the holders of our common stock in connection with the Closing of the Business Combination, (d) to satisfy the redemption rights of the holders of our common stock in connection with an Extension requiring a stockholder vote to amend the Charter (i) for an Extension or (ii) with respect to any other provision relating to stockholders' rights or pre-initial business combination activity, or (e) in connection with the redemption of our public shares upon our failure to complete our initial business combination, then the warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each share of our common stock in respect of such event.

If the number of outstanding shares of our common stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of our common stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of our common stock issuable on exercise of each Public Warrant will be decreased in proportion to such decrease in outstanding shares of our common stock.

Whenever the number of shares of our common stock purchasable upon the exercise of the Public Warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of shares of our common stock purchasable upon the exercise of the warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of shares of our common stock so purchasable immediately thereafter.

In case of any reclassification or reorganization of the outstanding shares of our common stock (other than those described above or that solely affects the par value of such shares of our common stock), or in the case of any merger or consolidation of us with or into another corporation (other than a consolidation or merger in which we are the continuing corporation and that does not result in any reclassification or reorganization of our outstanding shares of our common stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety in connection with which we are dissolved, the holders of the Public Warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the warrants and in lieu of the shares of our common stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the warrants would have received if such holder had exercised their warrants immediately prior to such event. If less than 70% of the consideration receivable by the holders of our common stock in such a transaction is payable in the form of our common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the warrant properly exercises the warrant within thirty days following public disclosure of such transaction, the warrant exercise price will be reduced as specified in the warrant agreement based on the Black-Scholes value (as defined in the warrant agreement) of the warrant. The purpose of such exercise price reduction is to provide additional value to holders of the warrants when an extraordinary transaction occurs during the exercise period of the warrants pursuant to which the holders of the warrants otherwise do not receive the full potential value of the warrants in order to determine and realize the option value component of the warrant. This formula is to compensate the warrant holder for the loss of the option value portion of the warrant due to the requirement that the warrant holder exercise the warrant within 30 days of the event. The Black-Scholes model is an accepted pricing model for estimating fair market value where no quoted market price for an instrument is available.

11

The Public Warrants and the Placement Warrants were issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and Pono. You should review a copy of the warrant agreement, which has been publicly filed with the SEC and which you can find in the list of exhibits to the Annual Report on Form 10-K incorporated by reference into this prospectus, for a complete description of the terms and conditions applicable to the warrants. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least a majority of the then outstanding Public Warrants to make any change that adversely affects the interests of the registered holders of Public Warrants.

The Public Warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of our common stock and any voting rights until they exercise their warrants and receive shares of our common stock. After the issuance of shares of our common stock upon exercise of the warrants, each holder will be entitled to one (1) vote for each share held of record on all matters to be voted on by stockholders.

No fractional shares will be issued upon exercise of the Public Warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number of shares of our common stock to be issued to the warrant holder.

Placement Warrants

Except as described below, the Placement Warrants have terms and provisions that are identical to those of the Public Warrants, including as to exercise price, exercisability and exercise period. The Placement Warrants (including our common stock issuable upon exercise of the Placement Warrants) are not transferable, assignable or salable until 30 days after the Closing (except, among certain other limited exceptions to our officers and directors and other persons or entities affiliated with the Sponsor) and will be entitled to registration rights, so long as they are held by the Sponsor or its permitted transferees. The Sponsor, or its permitted transferees, has the option to exercise the Placement Warrants on a cashless basis. The Placement Warrants will be subject to the same terms and conditions as the Public Warrants, and among other matters, be redeemable by us and exercisable by the holders on the same basis as the Public Warrants.

If holders of the Placement Warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering their warrants for that number of shares of our common stock equal to the quotient obtained by dividing (x) the product of the number of shares of our common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the "fair market value" (defined below) by (y) the fair market value. The "fair market value" shall mean the average reported last sale price of our common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of warrant exercise is sent to the warrant agent.

Dividends

We have not paid any cash dividends on our common stock to date and do not intend to pay cash dividends in the foreseeable future. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial conditions. The payment of any cash dividends will be within the discretion of our board of directors at such time. Further, if we incur any indebtedness, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.

12

Our Transfer Agent and Warrant Agent

The transfer agent for our common stock and warrant agent for our warrants is Continental Stock Transfer & Trust Company. We have agreed to indemnify Continental Stock Transfer & Trust Company in its roles as transfer agent and warrant agent, its agents and each of its stockholders, directors, officers and employees against all claims and losses that may arise out of acts performed or omitted for its activities in that capacity, except for any liability due to any gross negligence, willful misconduct or bad faith of the indemnified person or entity.

Certain Anti-Takeover Provisions of Delaware Law and our Amended and Restated Certificate of Incorporation and Bylaws

The Amended Charter and the Company's bylaws and the DGCL, contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by the Company's board of directors and therefore depress the trading price of the Company's common stock. These provisions could also make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the Company's board of directors or taking other corporate actions, including effecting changes in the management of the Company. Among other things, the Amended Charter and the Company's bylaws include provisions regarding:

the ability of the Company's board of directors to issue shares of preferred stock, including "blank check" preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;
the limitation of the liability of, and the indemnification of, the Company's directors and officers;
the exclusive right of the Company's board of directors to elect a director to fill a vacancy created by the expansion of the Company's board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on the Company's board of directors;
the requirement that directors may only be removed from the Company's board of directors for cause;
the requirement that a special meeting of stockholders may be called only by the Company's board of directors, the chairperson of the Company's board of directors, the Company's chief executive officer or the Company's president (in the absence of a chief executive officer), which could delay the ability of stockholders to force consideration of a proposal or to take action, including the removal of directors;
the procedures for the conduct and scheduling of board of directors and stockholder meetings;
the ability of the Company's board of directors to amend the bylaws, which may allow the Company's board of directors to take additional actions to prevent an unsolicited takeover and inhibit the ability of an acquirer to amend the bylaws to facilitate an unsolicited takeover attempt; and
advance notice procedures with which stockholders must comply to nominate candidates to the Company's board of directors or to propose matters to be acted upon at a stockholders' meeting, which could preclude stockholders from bringing matters before annual or special meetings of stockholders and delay changes in the Company's board of directors and also may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer's own slate of directors or otherwise attempting to obtain control of the Company.
13

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in the Company's board of directors or management.

Any provision of the Amended Charter, the Company's bylaws or Delaware law that has the effect of delaying or preventing a change in control could limit the opportunity for stockholders to receive a premium for their shares of the Company's capital stock and could also affect the price that some investors are willing to pay for the Company's common stock.

The Company is subject to statutory "anti-takeover" provisions under Delaware law; the provisions of Section 203 of the DGCL, an anti-takeover law. In general, Section 203 of the DGCL which may prohibit certain business combinations with stockholders owning 15% or more of the Company's outstanding voting stock. These anti-takeover provisions and other provisions in the Company's Amended Charter and amended and restated bylaws could make it more difficult for stockholders or potential acquirers to obtain control of the Company's board of directors or initiate actions that are opposed by the then-current board of directors and could also delay or impede a merger, tender offer or proxy contest involving the Company. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing or cause the Company to take other corporate actions you desire. Any delay or prevention of a change of control transaction or changes in the Company's board of directors could cause the market price of the Company's common stock to decline.

Certain provisions of the Company's amended and restated bylaws are intended to strengthen the position of the Company's board of directors in the event of a hostile takeover attempt. These provisions have the effect of providing the Company's board of directors with the sole power to fill vacancies on the Company's board of directors and providing that stockholders may only call a special meeting by the request, in writing, of stockholders owning individually or together ten percent (10%) or more of the entire capital stock of the corporation issued and outstanding and entitled to vote. The Company may include provisions in its certificate of incorporation that may discourage a third party from making a proposal to acquire us, even if some of its stockholders might consider the proposal to be in their best interests. For example, the Company may amend its certificate of incorporation to authorize its board of directors to issue one (1) or more classes or series of preferred stock that could discourage or delay a tender offer or change in control. In addition, the Company may enter into a stockholder rights plan, commonly known as a "poison pill," that may delay or prevent a change of control.

Exclusive Forum for Certain Lawsuits

The Amended Charter provides that, unless the Company consents in writing to the selection of an alternative forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on its behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of its directors, officers, or other employees to the Company or its stockholders, (iii) any action arising pursuant to any provision of the DGCL, or the certificate of incorporation or the bylaws or (iv) any other action asserting a claim that is governed by the internal affairs doctrine shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware), in all cases subject to the court having jurisdiction over indispensable parties named as defendants. The Amended Charter also provides that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. The exclusive forum provision will be applicable to the fullest extent permitted by applicable law, subject to certain exceptions. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. We note, however, that there is uncertainty as to whether a court would enforce this provision and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Section 22 of the Securities Act creates concurrent jurisdiction for state and federal courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

14

Any person or entity purchasing or otherwise acquiring any interest in any of the Company's securities shall be deemed to have notice of and consented to this provision. This exclusive-forum provision may limit a stockholder's ability to bring a claim in a judicial forum of its choosing for disputes with the Company or its directors, officers, or other employees, which may discourage lawsuits against the Company and its directors, officers, and other employees. If a court were to find the exclusive-forum provision to be inapplicable or unenforceable in an action, the Company may incur additional costs associated with resolving the dispute in other jurisdictions, which could harm its results of operations.

Registration Rights

The holders of the Founder Shares and Placement Units (and any securities underlying the Placement Units) are entitled to registration rights pursuant to the registration rights agreement that was signed at the time of the IPO, requiring the Company to register such securities for resale. The holders of the majority of these securities are entitled to make up to two demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain "piggy-back" registration rights with respect to registration statements filed subsequent to the completion of the Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Additionally, in connection with the closing of the Business Combination, the Company entered into registration rights agreements with certain stockholders.

Listing of Securities

The Company's common stock and warrants are currently quoted on the Nasdaq Global Market and the Nasdaq Capital Market, respectively, under the symbols "SBC" and "SBCWW," respectively.

SELLING SECURITYHOLDERS

The Selling Securityholders may offer and sell, from time to time, any or all of the shares of common stock they hold registered for resale covered by this prospectus.

This prospectus relates to the possible offer and resale from time to time by the Selling Securityholders of 98,796,461 shares of common stock under this prospectus.

The following table provides, as of December 23, 2025 (unless otherwise noted), information regarding the beneficial ownership of our securities held by each Selling Securityholder, the securities that may be sold by each Selling Securityholder under this prospectus and the number and percentage of securities that each Selling Securityholder will beneficially own after the offerings pursuant to this prospectus. Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act, and includes shares of common stock with respect to which the Selling Securityholders have voting and investment power.

The Selling Securityholders are not making any representation that any shares of common stock covered by this prospectus will be offered for sale. Because each Selling Securityholder may dispose of all, none or some portion of their securities, no estimate can be given as to the number of securities that will be beneficially owned by a Selling Securityholder upon completion of the offerings pursuant to this prospectus. For purposes of the table below, however, we have assumed that after completion of the offerings pursuant to this prospectus none of the securities covered by this prospectus will be beneficially owned by the Selling Securityholders and further assumed that the Selling Securityholders will not acquire beneficial ownership of any additional securities during the effective period of this prospectus. In addition, the Selling Securityholders may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time and from time to time, our securities in transactions exempt from the registration requirements of the Securities Act after the date on which the information in the table is presented.

We may amend or supplement this prospectus from time to time in the future to update or change this Selling Securityholders list and the securities that may be resold.

See the section entitled "Plan of Distribution" for further information regarding the securityholders' method of distributing these shares.

(1) The amounts and percentages of common stock beneficially owned are determined in accordance with the SEC's rules, pursuant to which a person is deemed to be a "beneficial owner" of a security if that person has or shares voting or investment power or has the right to acquire such power within 60 days through exercise of any option, warrant or other right. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person's ownership percentage, but not for purposes of computing any other person's percentage. Under these rules, more than one person may be deemed beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest. Except as otherwise indicated in these footnotes, each of the beneficial owners has, to our knowledge, sole voting and investment power with respect to the indicated shares of common stock.

PLAN OF DISTRIBUTION

General

We and/or the selling securityholders, and their pledgees, donees, transferees or other successors in interest, may sell the securities being offered by this prospectus in one or more of the following ways from time to time:

to or through underwriters or dealers;
through agents;
in "at the market offerings" to or through a market maker or into an existing trading market, or a securities exchange or otherwise;
directly to purchasers; or
through a combination of any of these methods of sale or by any other legally available means.

A distribution of the securities offered by this prospectus may also be effected through the issuance of derivative securities, including without limitation, warrants, subscriptions, exchangeable securities, forward delivery contracts and the writing of options. In addition, the manner in which we and/or the selling securityholders may sell some or all of the securities covered by this prospectus includes, without limitation, through:

a block trade in which a broker-dealer will attempt to sell as agent, but may position or resell a portion of the block, as principal, in order to facilitate the transaction;
purchases by a broker-dealer, as principal, and resale by the broker-dealer for its account;
ordinary brokerage transactions and transactions in which a broker solicits purchasers; or
privately negotiated transactions.

We may also enter into derivative, hedging, forward sale, option or other types of transactions. For example, we may:

enter into transactions with a broker-dealer or affiliate thereof in connection with which such broker-dealer or affiliate will engage in short sales of, or maintain short positions in, the common stock pursuant to this prospectus, in which case such broker-dealer or affiliate may use common stock received from us to close out or hedge its short positions;
sell securities short and redeliver such shares to close out or hedge our short positions;
enter into option or other types of transactions that require us to deliver common stock to a broker-dealer or an affiliate thereof, who will then resell or transfer the common stock under this prospectus; or
loan or pledge the common stock to a broker-dealer or an affiliate thereof, who may sell the loaned shares or, in an event of default in the case of a pledge, sell the pledged shares pursuant to this prospectus.

In addition, we may enter into derivative, hedging, forward sale, option or other types of transactions with third parties, or sell securities not covered by this prospectus to third parties, through a stock exchange, including block trades or ordinary broker's transactions, or through broker-dealers acting either as principal or agent, or through an underwritten public offering, through privately negotiated transactions or through a combination of any such methods of sale. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement or pricing supplement, as the case may be. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out or hedge any related short positions. We may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement or pricing supplement, as the case may be.

20

If indicated in an applicable prospectus supplement, we may sell shares of our common stock under a direct stock purchase and dividend reinvestment plan. The terms of any such plan will be set forth in the applicable prospectus supplement.

A prospectus supplement with respect to each series of securities will state the terms of the offering of the securities, including:

the terms of the offering;
the name or names of any underwriters, dealers or agents and the amounts of securities underwritten or purchased by each of them, if any;
the public offering price or purchase price of the securities and the net proceeds to be received by us from the sale;
any delayed delivery arrangements;
any initial public offering price;
any underwriting discounts and commissions or agency fees and other items constituting underwriters' or agents' compensation;
any discounts or concessions allowed or reallowed or paid to dealers; and
any securities exchange on which the securities may be listed.

The offer and sale of the securities described in this prospectus by us and/or the selling securityholders or the underwriters or the third parties described above may be effected from time to time in one or more transactions, including privately negotiated transactions, either:

at a fixed price or prices, which may be changed;
at market prices prevailing at the time of sale, including in "at the market offerings";
at prices related to the prevailing market prices; or
at negotiated prices.

Selling Securityholders

The selling securityholders, and their pledgees, donees, transferees or other successors in interest, may offer our securities in one or more offerings, and if required by applicable law or in connection with an underwritten offering, pursuant to one or more prospectus supplements, and any such prospectus supplement will set forth the terms of the relevant offering as described above. To the extent our securities offered by a selling stockholder pursuant to a prospectus supplement remain unsold, the selling stockholder may offer those securities on different terms pursuant to another prospectus supplement. Sales by the selling securityholders may not require the provision of a prospectus supplement.

In addition to the foregoing, each of the selling securityholders may offer our securities at various times in one or more of the following transactions: through short sales, derivative and hedging transactions; by pledge to secure debts and other obligations; through offerings of securities exchangeable, convertible or exercisable for our securities; under forward purchase contracts with trusts, investment companies or other entities (which may, in turn, distribute their own securities); through distribution to its members, partners or stockholders; in exchange or over-the-counter market transactions; and/or in private transactions.

21

Each of the selling securityholders also may resell all or a portion of our securities that the selling stockholder owns in open market transactions in reliance upon Rule 144 under the Securities Act provided the selling stockholder meets the criteria and conforms to the requirements of Rule 144.

We will not receive any of the proceeds from the sale of securities by selling securityholders.

Underwriting Compensation

Any public offering price and any fees, discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers, agents or remarketing firms may be changed from time to time. Underwriters, dealers, agents and remarketing firms that participate in the distribution of the offered securities may be "underwriters" as defined in the Securities Act. Any discounts or commissions they receive from us and/or the selling securityholders and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify any underwriters, agents or dealers and describe their fees, commissions or discounts in the applicable prospectus supplement or pricing supplement, as the case may be.

Underwriters and Agents

If underwriters are used in a sale, they will acquire the offered securities for their own account. The underwriters may resell the offered securities in one or more transactions, including negotiated transactions. We and/or the selling securityholders may offer the securities to the public either through an underwriting syndicate represented by one or more managing underwriters or through one or more underwriter(s). The underwriters in any particular offering will be identified in the applicable prospectus supplement or pricing supplement, as the case may be.

Unless otherwise specified in connection with any particular offering of securities, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions contained in an underwriting agreement that we and/or the selling securityholders will enter into with the underwriters at the time of the sale to them. The underwriters will be obligated to purchase all of the securities of the series offered if any of the securities are purchased, unless otherwise specified in connection with any particular offering of securities. Any initial offering price and any discounts or concessions allowed, reallowed or paid to dealers may be changed from time to time.

We and/or the selling securityholders may designate agents to sell the offered securities. Unless otherwise specified in connection with any particular offering of securities, the agents will agree to use their best efforts to solicit purchases for the period of their appointment. We and/or the selling securityholders may also sell the offered securities to one or more remarketing firms, acting as principals for their own accounts or as agents for us and/or the selling securityholders. These firms will remarket the offered securities upon purchasing them in accordance with a redemption or repayment pursuant to the terms of the offered securities. A prospectus supplement or pricing supplement, as the case may be will identify any remarketing firm and will describe the terms of its agreement, if any, with us and/or the selling securityholders, and its compensation.

In connection with offerings made through underwriters or agents, we and/or the selling securityholders may enter into agreements with such underwriters or agents pursuant to which we receive our outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us under these arrangements to close out any related open borrowings of securities.

22

Dealers

We and/or the selling securityholders may sell the offered securities to dealers as principals. We and/or the selling securityholders may negotiate and pay dealers' commissions, discounts or concessions for their services. The dealer may then resell such securities to the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with us at the time of resale. Dealers engaged by us may allow other dealers to participate in resales.

Direct Sales

We and/or the selling securityholders may choose to sell the offered securities directly to multiple purchasers or a single purchaser. In this case, no underwriters or agents would be involved.

Indemnification; Other Relationships

We and/or the selling securityholders may agree to indemnify underwriters, dealers, agents and remarketing firms against certain civil liabilities, including liabilities under the Securities Act and to make contributions to them in connection with those liabilities. Underwriters, dealers, agents and remarketing firms, and their affiliates, may engage in transactions with, or perform services for us, and our affiliates, in the ordinary course of business, including commercial banking transactions and services.

Market Making, Stabilization and Other Transactions

Each series of securities will be a new issue of securities and will have no established trading market, other than our common stock, which is listed on Nasdaq. Any common stock sold pursuant to a prospectus supplement will be listed on Nasdaq, subject to official notice of issuance. Any underwriters to whom we and/or the selling securityholders sell securities for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The securities, other than the common stock, may or may not be listed on a national securities exchange, and any such listing if pursued will be described in the applicable prospectus supplement.

To facilitate the offering of the securities, certain persons participating in the offering may engage in transactions that stabilize, maintain, or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involves the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover the over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

Issuance of Common Stock Underlying Warrants

Pursuant to the terms of the Warrants, the shares of Common Stock issuable upon exercise thereof will be distributed to those Warrant holders who surrender the certificates representing the Warrants and provide payment of the exercise price through their brokers to our warrant agent, Continental Stock Transfer & Trust Company.

23

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, certain legal matters will be passed upon for us by Simpson Thacher & Bartlett LLP. If the validity of any securities is also passed upon by counsel for the underwriters, dealers or agents of an offering of those securities, that counsel will be named in the applicable prospectus supplement.

EXPERTS

The financial statements of SBC Medical Group Holdings Incorporated as of December 31, 2024 and 2023, and for the years then ended, incorporated by reference in this prospectus have been so included in reliance upon the report of MaloneBailey, LLP, an independent registered public accounting firm, given on the authority of said firm as experts in accounting and auditing.

Our website address is http://sbc-holdings.com/en. The information on our website is not, and should not be deemed to be, a part of this prospectus.

This prospectus and any prospectus supplement are part of a registration statement that we filed with the SEC and do not contain all of the information in the registration statement. The full registration statement may be obtained from the SEC or us, as provided below. The documents establishing the terms of any offered securities are or may be filed as exhibits to the registration statement or documents incorporated by reference in the registration statement. Statements in this prospectus or any prospectus supplement about these documents are summaries and each statement is qualified in all respects by reference to the document to which it refers. You should refer to the actual documents for a more complete description of the relevant matters. You may inspect a copy of the registration statement through the SEC's website, as provided above.

INCORPORATION BY REFERENCE

The SEC's rules allow us to "incorporate by reference" information into this prospectus, which means that we can disclose important information to you by referring you to another document filed separately with the SEC. The information incorporated by reference is deemed to be part of this prospectus, and subsequent information that we file with the SEC will automatically update and supersede that information. Any statement contained in this prospectus or a previously filed document incorporated by reference will be deemed to be modified or superseded for purposes of this prospectus to the extent that a statement contained in this prospectus or a subsequently filed document incorporated by reference modifies or replaces that statement.

This prospectus and any accompanying prospectus supplement incorporate by reference the documents set forth below that have previously been filed with the SEC:
