ABOUT APPLIED ENERGETICS, INC.

Overview

Applied Energetics, Inc. specializes in advanced laser and photonics systems, particularly fiber-based ultrashort pulse (USP) laser technologies. With 28 patents and 5 patents pending, Applied Energetics' proprietary architecture enables orders of magnitude size-weight-power reductions, a key differentiator when compared with traditional continuous wave (CW) laser technology with larger footprints. AE's powerful, dual-use systems are designed for integration and deployment on numerous potential defense platforms for the delivery of high intensity, USPs of light to disable or destroy a target or disrupt a mission. These technologies have applications in both national security and commercial markets. Today, AE's USP optical technologies are being designed to offer flexibility and power for complex missions in national security such as enhancing layered defense strategies to counter complex threats.

Technology, Capabilities, and Patents

Applied Energetics, Inc. is as a leader in developing the next generation optical sources exhibiting ever-increasing output energy, peak power and frequency agility while also providing decreased size, weight, and cost of these systems for customers. Applied Energetics utilizes patented, dual-use technologies to advance critical industries. Leveraging our proprietary fiber-based architecture and wavelength- and pulse-agility capability, our USP technology can enable users to achieve specific effects across different use cases with an unmatched blend of size, weight, and power attributes. While initially designed to meet the emerging needs and priorities for the national security community, our directed energy technology also has commercial applications in both the biomedical and advanced manufacturing industries.

Our USP Lasers are designed to provide:

Frequency Agile Optical Sources from Ultraviolet (UV) to Far Infrared (IR)
Pulse Duration Agility
Size, Weight, and Power Optimization
Advanced Fiber Applications
Laser Guided Energy (LGE®)
Laser Induced Plasma Channel (LIPC®)

Applied Energetics' directed energy technologies are vastly different from conventional directed energy systems, i.e., Applied Energetics' proprietary fiber-based architecture is a key differentiator for our most recent technology demonstrators. Compared with traditional continuous wave laser technologies, with their larger footprints, AE's architecture enables orders of magnitude size-weight-power reductions on all deliverables, creating powerful, dual-use and agile systems that can fit a host of platforms while delivering very high-intensity, ultrashort pulses of light to the required target. This directed energy solution allows extremely high peak power and energy, with target and effects tunability, and is effective against a wide variety of potential targets.

Applied Energetics' optical fiber-based laser architectures also enable unmatched wavelength agility as well as pulse duration agility. Using innovative and highly specialized frequency shifting techniques, wavelengths can be custom tuned from the deep ultraviolet to the far infrared. In addition, temporal outputs can be adjusted from continuous wave to sub-picoseconds. The technology enables the customer to adjust the lasers' operating parameters, ultimately creating more flexibility to change wavelength and pulse width. This feature allows for optimization of laser performance for defense or commercial applications.

3

Our proprietary USP laser technology provides a significantly more compact solution than current continuous wave laser platforms while still delivering high peak power. Continuous wave laser systems are typically used to heat a target and, during continuous illumination, this heat transfer leads to melting or charring of the material. Using continuous wave output powers that now exceed 100 kilowatts (1kW = 1000 watts), it can take anywhere from seconds to minutes to impact a target. By contrast, Applied Energetics has delivered USP lasers to national security users that exceed five terawatts (1 TW = 1 trillion watts) in peak power, with the difference being that this peak power from a USP laser is delivered in a pulse that is less than a trillionth of a second. During this short pulse duration, and having such a high peak intensity, near-instantaneous ablation of the surface of the threat takes place. The net result of our innovative USP approaches is highly effective lasers capable of jamming, damaging, and destroying certain surveillance and reconnaissance sensors with mountable footprints that require only a fraction of the size, weight, and power requirements of other-directed energy technologies. We believe the combination of both low size, weight, and power characteristics with wavelength and pulse duration agility will help us achieve our vision statement of Directed Energy, Anywhere.

The Applied Energetics scientific team is continuously innovating with an eye toward expanding our patent portfolio to cover these technological breakthroughs and further enhance our suite of solutions for threat disruption for the Department of Defense, the intelligence community, and for commercial, biomedical and space applications with optical sources operating from the deep ultraviolet to the far infrared portions of the electromagnetic spectrum.

Applied Energetics has developed, successfully demonstrated, and holds all crucial intellectual property rights to a dynamic directed energy technology called Laser Guided Energy (LGE®) and Laser Induced Plasma Channel (LIPC®). LGE and LIPC are technologies that can be used in a new generation of high-tech directed energy systems. Applied Energetics' LGE and LIPC technologies are wholly owned by Applied Energetics and protected by one or more of Applied Energetics' 28 issued patents and 9 Government Sensitive Patent Applications (GSPA). These GSPA's are held under secrecy orders of the US government, providing the Company with extended protection rights.

More recently, the Company has been awarded a new patent for application in the national security domain (Pulsed Laser Thermal Excitation, Patent No.: US 12,171,055 B2) and received notice of an allowed patent application in the healthcare domain (Pathogen Detection and Neutralization Using Deep UV-C Generation Via Seeded Raman Amplification and Second Harmonic Generation, Patent Application No.: US 2023/01804590 A1). The Company also has five pending patent applications. We continue to file patent applications as we deem appropriate to protect our intellectual property and enhance our competitive advantage.

As Applied Energetics looks toward the future, our corporate strategic roadmap builds upon the significant value of the Company's USP laser capabilities and key intellectual property, including LGE and LIPC, to offer our prospective partners, co-developers and system integrators a variety of next-generation ultrashort pulse and frequency-agile optical sources, from the ultraviolet to the far infrared portion of the electromagnetic spectrum, to address numerous challenges within the national security, biomedical, and advanced manufacturing market sectors.

Transactions with Selling Stockholders

Each of the Selling Stockholders listed above purchased the shares registered for possible resale in one or more of the following transactions:

On May 10, 2024, the Company completed the placement of 1,896,182 shares of its common stock, par value, $0.001 per share, in a private sale to individual purchasers at a price of $2.20 per share, for aggregate proceeds in the amount of $4,171,600.

On January 14, 2025, the Company completed the placement of 6,405,666 shares of its common stock, par value, $0.001 per share, some of which were underlying pre-funded common stock purchase warrants, in a private sale to individual purchasers at a price of $0.75 per share (or $0.749 per underlying share for pre-funded warrants), for aggregate proceeds in the approximate amount of $ 4,804,249. The pre-funded warrants are exercisable immediately at a price of $0.001 per share but may not be executed in any amount which would cause the holder thereof to beneficially own 5% or more of the Company's common stock.

On February 6, 2025, the Company completed the placement of 1,600,000 shares of its common stock, par value, $0.001 per share, some of which were underlying pre-funded common stock purchase warrants, in a private sale to individual purchasers at a price of $0.75 per share (or $0.749 per underlying share for pre-funded warrants), for aggregate proceeds in the amount of $1,200,000. The pre-funded warrants are exercisable immediately at a price of $0.001 per share but may not be executed in any amount which would cause the holder thereof to beneficially own 5% or more of the Company's common stock. The Company has agreed to use its best efforts to include the shares for registration with the SEC in the registration statement it files.

On October 8, 2025, the Company completed the placement of 5,995,675 shares of its common stock, par value, $0.001 per share, some of which were underlying pre-funded common stock purchase warrants, in a private sale to individual purchasers at a price of $1.80 per share (or $1.799 per underlying share for pre-funded warrants), for aggregate proceeds in the amount of $10,789,999.

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 OTCQB 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 entered into after the effective date of the registration statement of which this prospectus is a part;
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 under the Securities Act of 1933, as amended (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 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440.

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).

9

We will pay all of the expenses incident to the registration, offering, and sale of the shares to the public other than commissions or discounts of underwriters, broker-dealers, or agents. Any commissions, discounts or other fees payable to brokers-dealers in connection with any sale of the shares of common stock will be borne by the selling stockholders, the purchasers participating in such transaction, or both.

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. We know of no existing arrangements between the selling stockholders, any other shareholder, broker, dealer, underwriter, or agent relating to the sale or distribution of the shares offered by this prospectus. In no event shall any broker-dealer receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%).

Because Selling Stockholders may be deemed to be "underwriters" within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder. In addition, any securities covered by this Prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this Prospectus.

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 or (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. 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 Securities Exchange Act of 1934, as amended (the "Exchange Act"), any person engaged in the distribution of the resale shares 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 shares 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).

Penny Stock Rules

Our shares of common stock are subject to the "penny stock" rules of the Exchange Act. In general terms, "penny stock" is defined as any equity security that has a market price less than $5.00 per share, subject to certain exceptions. The rules provide that any equity security is considered to be a penny stock unless that security is registered and traded on a national securities exchange meeting specified criteria set by the SEC, authorized for quotation from the NASDAQ stock market, issued by a registered investment company, and excluded from the definition on the basis of price (at least $5.00 per share), or based on the issuer's net tangible assets or revenues. In the last case, the issuer's net tangible assets must exceed $3,000,000 if in continuous operation for at least three years or $5,000,000 if in operation for less than three years, or the issuer's average revenues for each of the past three years must exceed $6,000,000.

10

Trading in shares of penny stock is subject to additional sales practice requirements for broker-dealers who sell penny stocks to persons other than established customers and accredited investors. Accredited investors, in general, include individuals with assets in excess of $1,000,000 or annual income exceeding $200,000 (or $300,000 together with their spouse), and certain institutional investors. For transactions covered by these rules, broker-dealers must make a special suitability determination for the purchase of the security and must have received the purchaser's written consent to the transaction prior to the purchase. Additionally, for any transaction involving a penny stock, the rules require the delivery, prior to the first transaction, of a risk disclosure document relating to the penny stock. A broker-dealer also must disclose the commissions payable to both the broker-dealer and the registered representative, and current quotations for the security. Finally, monthly statements must be sent disclosing recent price information for the penny stocks.

Item 15. Indemnification of Officers and Directors

Article NINTH of our Restated Certificate of Incorporation states:

All persons who the Corporation is empowered to indemnify pursuant to the provisions of Section 145 of the General Corporation Law of the State of Delaware (or any similar provision or provisions of applicable law at the time in effect), shall be indemnified by the Corporation to the full extent permitted thereby. The foregoing right of indemnification shall not be deemed to be exclusive of any other rights to which those seeking indemnification may be entitled under any by-law, agreement, vote of stockholders or disinterested directors, or otherwise. No repeal or amendment of this Article NINTH shall adversely affect any rights of any person pursuant to this Article NINTH which existed at the time of such repeal or amendment with respect to acts or omissions occurring prior to such repeal or amendment.

Article V of our First Amended and Restated Bylaws states: The Corporation shall indemnify and hold harmless to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit, or proceeding, whether civil, criminal, administrative, or investigative (a "Proceeding"), by reason of the fact that such person, or a person for whom such person is the legal representative, is or was a director, or officer, or employee, or agent of the Corporation or, while a director, or officer, or employee, or agent of the Corporation, is or was serving at the specific request communicated in writing from the Board of Directors of the Corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, enterprise, or nonprofit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys' fees) actually and reasonably incurred by such person. Notwithstanding the preceding sentence, the Corporation shall be required to indemnify a person in connection with a Proceeding (or part thereof) commenced by such person only if the commencement of such Proceeding (or part thereof) by the person was authorized in the specific case by the Board of Directors.

Section 145 of the Delaware General Corporation Law authorizes us to indemnify any director or officer under prescribed circumstances and subject to certain limitations against certain costs and expenses, including attorneys' fees actually and reasonably incurred in connection with any action, suit or proceedings, whether civil, criminal, administrative or investigative, to which such person is a party by reason of being one of our directors or officers if it is determined that the person acted in accordance with the applicable standard of conduct set forth in such statutory provisions.

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

Item 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(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;

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

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

provided, however, that paragraphs (a)(1)(i), (ii) and (iii) of this section shall 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 SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

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

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

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

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

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

II-3

(5) 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 Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the 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.

(6) That for purposes of determining any liability under the Securities Act,

(i) the information omitted from the form of prospectus filed as part of the registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the registrant pursuant to Rule 424(b)(l) or (4) or 497(h) under the Securities Act shall be deemed to be a part of the registration statement as of the time it was declared effective; and

(ii) each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offing of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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 foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC 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.
