Overview

We were incorporated under Delaware law in 1992 as the successor to LightPath Technologies Limited Partnership, a New Mexico limited partnership formed in 1989, and its predecessor, Integrated Solar Technologies Corporation, a New Mexico corporation formed in 1985. Today, we are a global company with facilities in the United States, the People's Republic of China and the Republic of Latvia.

We have four direct wholly owned subsidiaries. InNovember 2005,we formedLightPath Optical Instrumentation (Shanghai) Co., Ltd ("LPOI"), a wholly owned subsidiary, located in Jiading, People's Republic of China, which was primarily engaged in sales and support functions. In December 2013, we formed LightPath Optical Instrumentation (Zhenjiang) Co., Ltd. ("LPOIZ"), a wholly owned subsidiary located in the New City district, of the Jiangsu province, of the People's Republic of China. LPOIZ's manufacturing facility (the "Zhenjiang Facility") serves as our manufacturing facility in China and provides a lower cost structure for production of larger volumes of optical components and assemblies. Effective February 28, 2023, the legal entities of LPOI and LPOIZ were merged, with LPOIZ as the surviving company and the operations of the two companies were merged.

In December 2016, we acquired ISP Optics Corporation ("ISP"), and its wholly owned subsidiary, ISP Optics Latvia, SIA, a limited liability company founded in 1998 under the Laws of the Republic of Latvia ("ISP Latvia"). ISP is a vertically integrated manufacturer offering a full range of infrared products from custom infrared optical elements to catalog and high-performance lens assemblies. ISP's manufacturing operation is located at our corporate headquarters facility in Orlando, Florida (the "Orlando Facility"). ISP Latvia is a manufacturer of high precision optics and offers a full range of infrared products, including catalog and custom infrared optics. ISP Latvia's manufacturing facility is located in Riga, Latvia (the "Riga Facility").

In July 2023, we acquired Liebert Consulting, LLC, dba Visimid Technologies ("Visimid"), an engineering and design firm, specializing in thermal imaging, night vision and internet of things ("IOT") applications. Visimid provides design and consulting services for U.S. Department of Defense ("DoD") contractors, commercial and industrial customers, and original equipment manufacturers ("OEMs") for original new products. Visimid's core competency is developing and producing custom thermal and night vision cores. Visimid's facility is located in Plano, Texas.

In February 2025, we acquired G5 Infrared LLC ("G5 Infrared"), a New Hampshire limited liability company. G5 Infrared is a leading vertically-integrated manufacturer of high- performance infrared camera systems and imaging solutions, specializing in advanced thermal imaging technology and long-range mission-critical detection solutions. G5 Infrared's existing revenue and future growth pipeline are driven by established multi-year contracts and multiple defense programs of record in shipboard long-range surveillance, border security, and counter unmanned aerial systems ("C-UAS") systems, as well as recurring federal, naval, and law enforcement programs. Additionally, G5 Infrared is an industry-leading provider of cutting-edge advanced infrared coatings, including for materials such as LightPath's BlackDiamond ("BlackDiamond") glass. G5 Infrared operates from a state-of-the-art manufacturing facility in Hudson, New Hampshire. We believe that this acquisition strengthens LightPath's position as a leader in infrared imaging by expanding the Company's portfolio to include cooled infrared cameras. The combination of LightPath and G5 Infrared creates a more robust, vertically-integrated solutions provider.

Our Product Groups

We categorize our products into four product groups: (i) infrared components, (ii) visible components, (iii) assemblies and modules, and (iv) engineering services. G5 Infrared's revenue is generally derived from infrared components (including coating services) and assemblies and modules.

Infrared Components Product Group. Our infrared product group is comprised of both molded and turned infrared lenses using a variety of infrared glass materials. This product group also includes revenue from sales of our BlackDiamond glass materials, and G5's optical component and coating business. This product group includes both conventional and CNC ground and polished lenses. Advances in chalcogenide materials have enabled compression molding for mid-wave ("MWIR") and long-wave ("LWIR") optics in a process similar to precision molded lenses. Our molded infrared optics technology enables high performance, cost-effective infrared aspheric lenses that do not rely on traditional diamond turning or lengthy polishing methods. Utilizing precision molded aspheric optics significantly reduces the number of lenses required for typical thermal imaging systems and the cost to manufacture these lenses. Molding is an excellent alternative to traditional lens processing methods particularly where volume and repeatability is required.

We offer Germanium, silicon or zinc selenide aspheres and spherical lenses, which are manufactured by diamond turning. This manufacturing technique allows us to offer larger lens sizes and the ability to use other optical materials that cannot be effectively molded. Our numerous manufacturing capabilities allow us to meet complex optical challenges that demand more exotic optical substrate materials that are non-moldable, as well as larger size optics.

We also have the ability to manufacture chalcogenide glass from which we produce infrared lenses. We developed this glass and melt it internally to produce our BlackDiamond glass, which has been trademarked, and is marketed as BD6. Historically, the majority of our thermal imaging products have been germanium-based, which is subject to market pricing and availability. BD6 offers a lower-cost alternative to germanium, which is beneficial to the cost structure of some of our current infrared products and we expect it will allow us to continue to expand our product offerings in response to the markets' increasing requirement for low-cost infrared optics applications. During fiscal year 2024, we also formally announced availability of BDNL-4, the first of our new materials licensed from the NRL. BDNL-4 is unique because it has a negative thermo-optic coefficient, an attribute that is key in a-thermalization of optical systems.

We have the capability to manufacture lenses from very small (with diameters of sub-millimeter) to over 300 millimeters, and with focal lengths from approximately 0.4 millimeters to over 2000 millimeters, utilizing our various manufacturing methods. In addition, we offer both catalog and custom designed infrared optics.

Overall, we anticipate moderate growth for our infrared components, particularly as our germanium alternatives continue to be adopted into new applications and designs. This product group also supports our assemblies and modules product group.

Visible Components Product Group. Aspheric lenses are known for their optimal performance. Aspheric lenses simplify and shrink optical systems by replacing several conventional lenses. However, aspheric lenses can be difficult and costly to machine. Our glass molding technology enables the production of both low and high volumes of aspheric optics, while still maintaining the highest quality at an affordable price. Molding is the most consistent and economical way to produce aspheres and we have perfected this method to offer the most precise molded aspheric lenses available.

Assemblies and Modules Product Group. Our assemblies and modules product group is comprised of both optical assemblies such as lens systems, and cameras, both in the form of camera modules and complete camera systems. Historically this product group also included optical fiber collimators and some visible lens assemblies, however those are now a very small part of our activity, making infrared cameras and assemblies the most dominant part of this group. Today, the majority of the revenue of this group is derived from cameras made in our Texas facility (uncooled camera systems and modules), cameras made in our New Hampshire facility (cooled cameras for long range surveillance and detection), and optical assemblies such as standard off the shelf lens assemblies, and custom lens assemblies. The latter of which are produced mainly in Orlando.

Engineering Services Product Group. We develop products pursuant to development agreements that we enter into with customers. Typically, customers approach us and request that we develop new products or applications utilizing our existing products to fit their particular needs or specifications. The purpose of those engineering services that we offer is not only to provide purely engineering services for a customer, but also to engineer new products which we later manufacture for the customer. The timing and extent of any such product development requests are unpredictable and outside of our control.

Our Technologies

We believe that to be the preferred partner to fulfill the photonics needs of our customers, domain expertise and differentiating technologies in photonics are key elements. Optics and photonics require multidisciplinary skills, including physics, mechanical engineering, material sciences, electrical engineering, and chemistry, among others. This is part of what makes using photonics so complicated, and at the same time part of what we see as the opportunity. Knowing what can and cannot be produced, designing the architecture and detailed design of the optical system, including electrical and mechanical interfaces, choosing and executing advanced manufacturing technologies, and delivering both the engineering prototypes that are needed, as well as producing a high volume of goods for the long-term, are all part of the domain expertise required. Additionally, to design the best solution for a customer, we not only need to know what can be produced and how to design it, we also must have unique capabilities that differentiate our solutions. Such technologies allow us to develop solutions and sub systems that outperform other solutions in size, weight, power, and cost.

Along those lines, we continue to focus on developing, acquiring and licensing new, innovative capabilities and technologies in all of our engineering and manufacturing groups, including systems design and testing, optical fabrication of components, material production, optical coatings, and electro mechanical design and production such as the following:

·

Infrared Imaging Technologies. Our optical solutions strategy focuses around infrared imaging. Infrared imaging is a growing market, with technology that is evolving at a fast rate, and in which we have distinct advantages, based on our core technologies. Continually evolving and developing our technologies is key to maintaining and continuing to build and develop technical leadership, which translates to better products, which translate to creating value, and capturing value. While the basis of our infrared technology originally centered around infrared materials and optics, it has become more than that. As we evolve from a pure optics company to an integrator and solution provider, our differentiating technologies are evolving. Those differentiating technologies are often at a system or application level, rather than at the component or material level. Some of those technologies are gained through acquisitions, such as Visimid, and most recently G5 Infrared, which added advanced cooled, long-range infrared camera systems to our portfolio. G5 Infrared's expertise in system integration, image stabilization, and ruggedized, defense-qualified platforms significantly expands our capabilities beyond uncooled solutions and imaging systems, positioning us as one of the few companies capable of addressing the full spectrum of infrared imaging applications, from compact commercial cameras to long-range defense and border security systems.

A key differentiator of our infrared imaging portfolio is the integration of our proprietary BlackDiamond materials into camera designs. Unlike Germanium, which is subject to severe supply chain constraints and geopolitical risks, BlackDiamond materials are U.S.-produced and globally sourced, offering secure supply and unique technical benefits such as multispectral performance and low thermo-optic coefficients. In 2025, we announced the redesign of several G5 Infrared cooled cameras, where Germanium lenses were replaced with lenses made from BlackDiamond materials. This shift not only mitigates supply chain risk for Germanium but also improves system performance, lowers thermal sensitivity, and reduces cost. Other recent examples of such system-level capabilities include our development of a novel, unique approach to shutterless imaging that we can apply to microbolometer based cameras, and development of a technology for early detection of flames and fires using a combination of optical technologies and sophisticated image processing algorithms.

·

Optical Assemblies and Testing . When we began shifting our focus from optical components to solutions, doing more optical assemblies was a natural first step for us. During the first couple of years of implementing our new strategic direction, our team expanded our optical assemblies business and capabilities considerably. As our reputation in the assemblies space grew, so did the level of complexity of assemblies and sub-systems customers request of us. This trend was recently amplified when we began making available our new, exclusive infrared glass materials, which enable customers to design systems that far exceed the performance of existing systems using conventional materials.

BlackDiamond materials provide a unique advantage in our assemblies. Because these glasses are designed, produced, and integrated within LightPath, we can deliver assemblies with unmatched speed and flexibility, ensuring shorter lead times for our customers. Moreover, our ability to build assemblies that are not based on Germanium optics gives us a differentiated position in the defense and security markets, where supply chain risk and strategic sourcing are increasingly critical factors. These assemblies not only reduce reliance on foreign-controlled materials but also offer superior optical performance in multispectral and athermalized designs.

Often, the new systems requested by customers require us to develop new assembly and testing capabilities. Each such new capability and technique we develop for such projects become another capability and technique we can market and offer to other customers. We expect this will create selfperpetuating development opportunities as our new capabilities and techniques bring in more business that may, again, require continuing development of new techniques.

·

Materials. Materials play an important role in providing design flexibility and allow tradeoffs between optical performance, weight, and performance in varying conditions. Additionally, the infrared imaging industry has traditionally relied heavily on the use of Germanium and Gallium (in the form of GaAs glass), which China dominates the supply of both materials and has been restricting its export. Traditionally, infrared applications have only a small number of materials, almost all of which are crystal based, with Germanium being the most commonly used material. Over the last few years LightPath has been investing in developing and commercializing our BlackDiamond glasses (which are labeled with a "BD" prefix) as alternatives to using Germanium. Some of these materials such as BD6 and BD2, are generic, and are produced by at least two other companies. The crown jewels of our materials, the BDNL type, are exclusive to us, and the most impactful to our products and to the market as a whole in terms of technology, innovation and value creation. In December 2021 we secured an exclusive license from the U.S. government for the Chalcogenide materials that have been developed by the NRL. Following a two-year effort to transition those new materials into production, we began making available for commercial use some of those new materials, starting with the introduction of BDNL-4 in April 2024. Our BlackDiamond materials offer multiple advantages over materials, such as Germanium. It is estimated that over 67% of the global Germanium supply originates out of China, with Russia being the second largest supplier. Those two countries together control over 90% of the supply of Germanium and Gallium, two critical materials in infrared optics. Restrictions on supply from Russia and China have increased prices of Germanium from around $1,000 per Kg a few years ago, to a price of over $4,000 a Kg today. Additionally, supply of Germanium has considerably shrunk and for most customers and applications is not available at all.

Our BlackDiamond materials, which are made in the USA and produced from raw ingredients available from many countries all over the globe, offer an alternative to the use of Germanium in infrared systems. Knowing that our materials are produced domestically and have a secure supply chain has been driving sales growth in our business and in particular in the defense sector. In addition to providing an alternative to the use of Germanium, the new materials we licensed exclusively from the NRL have unique technical advantages compared to traditional materials, including multispectral performance and low thermo-optic coefficients, making them less affected by changes in environmental temperature. The combination of providing an alternative to the use of Germanium and Gallium, together with distinct technological advantages, make these materials which we own exclusively, a very desirable and key element in every future infrared system.

As described above in Growth Strategy, we leverage these unique advantages to become not only the supplier of choice for materials and optics, but also to be producer of the subsystems and complete imaging solutions, a much larger part of the system than we previously had as a component manufacturer. The importance of those materials, both from a supply chain resilience perspective as well as from a technology leadership perspective has led to some significant collaborations and efforts together with various governmental groups, and in particular with the U.S. DoD. As announced on several separate occasions, LightPath has received funded development contracts from the U.S. DoD, the Defense Logistics Agency, the European Space Agency, and the U.S. Army, among others. Those fundings are all aimed at accelerating the qualification of the materials for use in their respective applications. We continue to develop those technical capabilities and materials, both using internal funding and federal funding. We expect infrared materials to continue to be an important technology in our portfolio.

·

High precision molded lenses. Historically, precision molding of lenses is the key technology we have built upon. Precision molding of optics is a unique technology that is well suited for both high volume production of optical components, as well as production of optics with unique shapes, which otherwise would require a very lengthy and complex process to individually polish each lens to shape. Precision molded optics ("PMOs") is a technology in which we continuously invest to pursue advancements in what materials can be molded and the shapes and sizes of the optics we can mold. Although there are several other competitors that can mold optical elements, we have an established leadership position in this area as the original developer of the technology, and we believe we are the preferred vendor for the most complex, high-end projects of many of our customers. Some recent advancements we have made in precision molded optics include molding of non-symmetric shapes such as freeform optical components, and qualifying new materials for availability as moldable materials.

·

Traditional polishing and diamond turned optics. Our capabilities include a wide range of traditional fabrication processes. These include CNC (computer numerical control) grinding and polishing of optical elements, traditional grinding and polishing of lenses, and diamond turning of infrared materials.

·

Optical coatings. Thin film coatings are designed to reduce losses and protect the optical material, which are a key part of any optical system. Through our recent investments, we have the ability to coat lenses in all of our facilities, providing efficient, high quality antireflective coatings, as well as reflective and protective coatings. Our coating facilities employ both physical vapor deposition techniques as well as chemical vapor deposition techniques. In addition to our library of dozens of standard coatings, our coating engineers often design coatings specific for an application, optimizing the performance of the system for a specific customer use. One of our most known advanced coatings is Diamond Like Carbon, which provides materials such as chalcogenide glass significant environmental protection. This coating is currently available only at a small number of vendors, and is an example of a capability that we believe gives us a competitive advantage by allowing us to design better optical solutions.

The following is a summary of all material characteristics of our capital stock as set forth in our Certificate of Incorporation, as amended (the "Certificate of Incorporation") and our Amended and Restated Bylaws, as further amended (the "Bylaws"), and as registered under Section 12 of the Exchange Act. The summary does not purport to be complete and is qualified in its entirety by reference to our Certificate of Incorporation and our Bylaws, each of which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part and to the provisions of the Delaware General Corporate Law (the "DGCL"). We encourage you to review complete copies of our Certificate of Incorporation and our Bylaws, and the applicable provisions of the DGCL for additional information.

General

Our authorized capital stock consists of 105,000,000 shares, divided into 100,000,000 shares of common stock, par value $0.01 per share (the "Common Stock"), and 5,000,000 shares of preferred stock, par value $0.01 per share ("Preferred Stock"). Under our Certificate of Incorporation, our board of directors (our "Board") has the authority to issue such shares of Common Stock and Preferred Stock in one or more classes or series, with such voting powers, designations, preferences and relative, participating, optional or other special rights, if any, and such qualifications, limitations or restrictions thereof, if any, as shall be provided for in a resolution or resolutions adopted by our Board and filed as designations.

Class A Common Stock

Of the 100,000,000 shares of Common Stock authorized in our Certificate of Incorporation, our Board has designated 94,500,000 shares as Class A Common Stock, par value $0.01 per share, or the Class A Common Stock. As of September 26, 2025, 44,670,213 shares of our Class A Common Stock were outstanding. The remaining 5,500,000 shares of authorized Common Stock were designated as Class E-1 Common Stock, Class E-2 Common Stock, or Class E-3 Common Stock, all previously outstanding shares of which have been previously redeemed or converted into shares of our Class A Common Stock.

Holders of our Class A Common Stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders, including the election of directors, and are entitled to receive dividends when and as declared by our Board out of funds legally available therefore for distribution to stockholders and to share ratably in the assets legally available for distribution to stockholders in the event of the liquidation or dissolution, whether voluntary or involuntary, of LightPath. We have not paid any dividends and do not anticipate paying any dividends on our Class A Common Stock in the foreseeable future. It is our present policy to retain earnings, if any, for use in the development of our business. Our Class A Common Stockholders do not have cumulative voting rights in the election of directors and have no preemptive, subscription, or conversion rights. Our Class A Common Stock is not subject to redemption by us.

As of September 26, 2025, we have reserved for issuance 1,080,953 shares of our Class A Common Stock underlying outstanding restricted stock units, 121,912 shares of our Class A Common Stock underlying outstanding restricted stock awards, 717,035 shares of our Class A Common Stock for issuance upon the exercise of outstanding stock options, 4,170,347 shares of our Class A Common Stock for issuance under the 2018 Stock and Incentive Compensation Plan, and 400,000 shares of our Class A Common Stock for issuance under our 2025 Employee Stock Purchase Plan.

The transfer agent and registrar for our Class A Common Stock is Computershare Trust Company, N.A.

Preferred Stock

Of the 5,000,000 shares of preferred stock authorized, our Board has previously designated:

·

250 shares of Preferred Stock as Series A Preferred Stock, all previously outstanding shares of which have been previously redeemed or converted into shares of our Class A Common Stock and may not be reissued;

·

300 shares of Preferred Stock as Series B Preferred Stock, all previously outstanding shares of which have been previously redeemed or converted into shares of our Class A Common Stock and may not be reissued;

·

500 shares of Preferred Stock as Series C Preferred Stock, all previously outstanding shares of which have been previously redeemed or converted into shares of our Class A Common Stock and may not be reissued;

·

500,000 shares of Preferred Stock as Series D Preferred Stock, none of which have been issued; however, in 1998, our Board declared a dividend distribution as a right to purchase one share of Series D Preferred Stock for each outstanding share of Class A Common Stock upon occurrence of certain events. The rights expired on February 28, 2021;

·

500 shares of Preferred Stock as Series F Preferred Stock, all previously outstanding shares of which have been previously redeemed or converted into shares of our Class A Common Stock and may not be reissued; and

·

35,111 shares of Preferred Stock as Series G Convertible Preferred Stock.

Of the 5,000,000 shares of Preferred Stock, 4,463,339 shares of our Preferred Stock remain available for designation by our Board. Accordingly, our Board is empowered, without stockholder approval, to issue Preferred Stock with dividend, liquidation, conversion, voting or other rights that could adversely affect the voting power or other rights of the holders of Common Stock. The issuance of Preferred Stock could have the effect of restricting dividends on the Class A Common Stock, diluting the voting power of the Class A Common Stock, impairing the liquidation rights of the Class A Common Stock, or delaying or preventing a change in control of us, all without further action by our stockholders.

Options

As of September 26, 2025, we had 717,035 shares of our Class A Common Stock underlying stock options outstanding, having a weighted-average exercise price of approximately $2.12 per share.

Warrants

As of September 26, 2025, we had 4,523,471 warrants outstanding to purchase shares an aggregate of 4,523,471 shares of Class A Common Stock (collectively, the "Warrants").

The Warrants have an exercise price equal to $2.58 per share (the "Exercise Price"). The Exercise Price and the number of underlying shares of Class A Common Stock are subject to proportional adjustment in the event of customary stock splits, stock dividends, combinations or similar events. The Warrants will expire on February 18, 2031, the six-year anniversary of issuance, and are exercisable at any time on or after the issuance date. The Warrants may be exercised on a cashless basis at any time, at the election of the holder in its sole discretion, and the Warrants will automatically be exercised on a cashless basis upon the expiration of the Warrants if not otherwise exercised prior thereto.

Certain Provisions of our Certificate of Incorporation, our Bylaws, and the DGCL

Certain provisions in our Certificate of Incorporation and Bylaws, as well as certain provisions of the DGCL, may be deemed to have an anti-takeover effect and may delay, deter, or prevent a tender offer or takeover attempt that a stockholder might consider to be in its best interests, including attempts that might result in a premium being paid over the market price of the shares held by stockholders. These provisions contained in our Certificate of Incorporation and Bylaws include the items described below.

·

Classified Board . Our Certificate of Incorporation provides that our Board is to be divided into three classes, as equal in number as possible, with directors in each class serving three-year terms. Provisions of this type may serve to delay or prevent an acquisition of us or a change in our directors and officers.

·

No Written Consents . Our Certificate of Incorporation and Bylaws provide that all stockholder actions must be effected at a duly called meeting of stockholders and not by written consent.

·

Special Meetings of Stockholders . Our Bylaws provide that special meetings of our stockholders may be called only by the Chairman of the Board, President, or a majority of our Board.

·

Stockholder Advance Notice Procedures . Our Bylaws provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide timely notice in writing and also specify requirements as to the form and content of a stockholder's notice. These provisions may delay or preclude stockholders from bringing matters before a meeting of our stockholders or from making nominations for directors at a meeting of stockholders, which could delay or deter takeover attempts or changes in our management.

·

No Cumulative Voting . Our Certificate of Incorporation does not include a provision for cumulative voting for directors. Under cumulative voting, a minority stockholder holding a sufficient percentage of a class of shares could be able to ensure the election of one or more directors.

·

Exclusive Forum . Our Bylaws provide that unless we consent in writing to the selection of an alternative forum, the courts in the State of Delaware are, to the fullest extent permitted by applicable law, the sole and exclusive forum for any claims, including claims in the right of the Company, brought by a stockholder (i) that are based upon a violation of a duty by a current or former director or officer or stockholder in such capacity or (ii) as to which the DGCL confers jurisdiction upon the Court of Chancery of the State of Delaware.

·

Undesignated Preferred Stock . Because our Board has the power to establish the preferences and rights of the shares of any additional series of Preferred Stock, it may afford holders of any Preferred Stock preferences, powers, and rights, including voting and dividend rights, senior to the rights of holders of our Class A Common Stock, which could adversely affect the holders of our Class A Common Stock and could discourage a takeover of us even if a change of control of LightPath would be beneficial to the interests of our stockholders.

These and other provisions contained in our Certificate of Incorporation and Bylaws are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our Board. However, these provisions could delay or discourage transactions involving an actual or potential change in control of us, including transactions in which stockholders might otherwise receive a premium for their shares over then current prices. Such provisions could also limit the ability of stockholders to remove current management or approve transactions that stockholders may deem to be in their best interests.

In addition, we are subject to the provisions of Section 203 of the DGCL. Section 203 of the DGCL prohibits a publicly-held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the person became an interested stockholder, unless:

·

The board of directors of the corporation approved the business combination or other transaction in which the person became an interested stockholder prior to the date of the business combination or other transaction;

·

Upon consummation of the transaction that resulted in the person becoming an interested stockholder, the person owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding, shares owned by persons who are directors and also officers of the corporation and shares issued under which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

·

On or subsequent to the date the person became an interested stockholder, the board of directors of the corporation approved the business combination and the stockholders of the corporation authorized the business combination at an annual or special meeting of stockholders by the affirmative vote of at least 66-2/3% of the outstanding voting stock of the corporation that is not owned by the interested stockholder.

A "business combination" includes mergers, asset sales, and other transactions resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an "interested stockholder" is a person who, together with affiliates and associates, owns, or within the prior three years did own, 15% or more of a corporation's voting stock.

Section 203 of the DGCL could depress our stock price and delay, discourage, or prohibit transactions not approved in advance by our Board, such as takeover attempts that might otherwise involve the payment to our stockholders of a premium over the market price of our Class A Common Stock.

Limitation of Liability and Indemnification of Officers and Directors

Our Certificate of Incorporation limits the personal liability of directors for breach of fiduciary duty to the maximum extent permitted by the DGCL. Our Certificate of Incorporation provides that no director will have personal liability to us or to our stockholders for monetary damages for breach of fiduciary duty or other duty as a director, except for:

·

any breach of the director's duty of loyalty to us or our stockholders;

·

acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

·

any transaction from which the director derived an improper personal benefit; or

·

under Section 174 of the DGCL.

Any amendment to or repeal of these provisions will not eliminate or reduce the effect of these provisions in respect of any act or failure to act, or any cause of action, suit or claim that would accrue or arise prior to any amendment or repeal or adoption of an inconsistent provision. If the DGCL is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the Delaware Law.

In addition, our Bylaws provides that we are required to indemnify to the fullest extent permitted by applicable law, any person made or threatened to be made a party or involved in a lawsuit action or proceeding by reason that such person is or was our officer, director, employee, or agent. Indemnification is against all liability and loss suffered and expenses reasonably incurred to the fullest extent permitted by applicable law. Unless required by law, no such indemnification is required by us of any person initiating such suit, action, or proceeding without Board authorization. Expenses are payable in advance if, to the extent required by law, the indemnified party agrees to repay the amount if he or she is ultimately found to not be entitled to indemnification.

The Bylaws further provide that the indemnification rights provided for in the Bylaws shall not be deemed exclusive of any rights to the indemnified party under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

We provide indemnity insurance pursuant to which officers and directors are indemnified or insured against liability or loss under certain circumstances, which may include liability or related loss under the Securities Act and the Exchange Act.

SELLING STOCKHOLDERS

The following table sets forth certain information provided to us by the selling stockholders with respect to the beneficial ownership of our Class A Common Stock by the selling stockholders as of September 26, 2025. The following table assumes that the selling stockholders sell all of their shares; however, we are unable to determine the exact number of shares that will actually be sold. The percentage of shares beneficial owned prior to the offering is based on 44,670,213 shares outstanding at September 26, 2025, determined in accordance with Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rule, beneficial ownership includes any shares as to which the individual has sole or shared voting power or investment power and also any shares which the individual has the right to acquire within sixty days of September 26, 2025, through the exercise of any warrants or other right.

PLAN OF DISTRIBUTION

Each selling stockholder of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on The Nasdaq Capital Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling stockholder may use any one or more of the following methods when selling securities:

·

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

·

block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

·

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

·

an exchange distribution in accordance with the rules of the applicable exchange;

·

privately negotiated transactions;

·

settlement of short sales;

·

in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

·

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

·

a combination of any such methods of sale; or

·

any other method permitted pursuant to applicable law.

The selling stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The selling stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

We are required to pay certain fees and expenses incurred by us incident to the registration of the securities. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the selling stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect, (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect, or (iii) the three year anniversary of the effective date of the registration statement. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Certain legal matters in connection with the issuance and sale of our securities offered hereby will be passed on for us by Baker & Hostetler LLP, Orlando, Florida.

Item 15. Indemnification of Directors and Officers.

Section 145 of the DGCL provides for the indemnification of officers and directors of corporations in terms sufficiently broad to indemnify our officers and directors under certain circumstances from liabilities (including reimbursement of expenses incurred) arising under the Securities Act. Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) in respect of certain unlawful dividend payments or stock redemptions or repurchases, or (iv) for any transaction from which the director derived an improper personal benefit.

As permitted by the DGCL, our Certificate of Incorporation provides that the personal liability of each member of our Board or our stockholders for monetary damages for breach of fiduciary duty as a director is eliminated. The effect of this provision in the Certificate of Incorporation is to eliminate our rights and the rights of our stockholders (through stockholders' derivative suits on our behalf) to recover monetary damages against a director for breach of fiduciary duty as a director thereof (including breaches resulting from negligent or grossly negligent behavior) except in the situations described in clauses (i)-(iv), inclusive, above. Specifically, Article TENTH of the Certificate of Incorporation provides as follows:

TENTH: No director of the corporation shall be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for any transaction from which the director derived an improper personal benefit, or (iv) under Section 174 of the GCL. This Article shall eliminate or limit the liability of a director for any act or omission occurring prior to the time this Article became effective.

In addition, Article 7 of our Bylaws provides, in summary, that we are required to indemnify to the fullest extent permitted by applicable law, any person made or threatened to be made a party or involved in a lawsuit action or proceeding by reason that such person is or was our officer, director, employee, or agent. Indemnification is against all liability and loss suffered and expenses reasonably incurred to the fullest extent permitted by applicable law. Unless required by law, no such indemnification is required by us of any person initiating such suit, action, or proceeding without Board authorization. Expenses are payable in advance if the indemnified party agrees to repay the amount if he or she is ultimately found to not be entitled to indemnification.

The Bylaws further provide that the indemnification rights provided for in the Bylaws shall not be deemed exclusive of any rights to the indemnified party under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

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

We provide indemnity insurance pursuant to which officers and directors are indemnified or insured against liability or loss under certain circumstances, which may include liability or related loss under the Securities Act and the Exchange Act.

Exhibits and/or schedules have been omitted pursuant to Item 601(a)(5) and/or 601(b)(10)(iv) of Regulation S-K. The registrant hereby undertakes to furnish supplementally copies of any of the omitted exhibits and schedules upon request by the SEC; provided, however, that the registrant may request confidential treatment pursuant to Rule 24b-2 of the Exchange Act for any exhibits or schedules so furnished.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

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

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended, or the Securities Act;

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

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are incorporated by reference in this registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement.

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

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

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

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

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

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

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