[S-3] Amplitech Group, Inc. Warrants Shelf Registration Statement

Rhea-AI Filing Summary

Savers Value Village, Inc. (SVV) filed a Form 144 indicating that an insider intends to sell up to 600 common shares through Fidelity Brokerage Services on or after 22 Jul 2025. Based on the reference price in the notice, the stake is valued at $6,306. With 157,451,564 shares outstanding, the proposed sale equals roughly 0.0004 % of the float, implying negligible market impact.

The seller, identified in the three-month sales table as Richard Medway, has already disposed of 36,513 shares between May and July 2025 for gross proceeds of about $402 k. The 600 shares originate from a stock option granted 12 Jun 2019 and exercised for cash on the planned sale date.

This filing is routine compliance with Rule 144 for restricted/control securities. Given the de-minimis size relative to daily volume and market cap, the event is unlikely to influence valuation, though investors may note the ongoing insider selling trend.

Positive

• None.

Negative

• Ongoing insider selling: The filer disposed of 36,513 shares in the past three months and now plans an additional 600-share sale, which some investors may view cautiously despite the small size.

Insights

Securities Analyst

600-share Form 144; negligible vs float; cumulative 36k shares sold; transaction routine; unlikely to move SVV valuation.

The proposed 600-share sale represents just 0.0004 % of Savers Value Village’s outstanding stock and follows earlier dispositions totalling 36,513 shares (~0.02 % of float). Such volumes will not affect supply-demand dynamics or dilute existing holders. The shares stem from an option exercised the same day, signalling normal liquidity management rather than strategic exit. Absent wider insider selling or adverse fundamentals, market impact is neutral.

Corporate Governance Expert

Insider’s continued disposals small but persistent; monitor alignment, though current filing alone lacks material significance.

Rule 144 disclosures enhance transparency on insider trading. While 600 shares is trivial, four earlier sales in three months show the individual gradually trimming exposure. Percentages remain immaterial, yet persistent selling can draw scrutiny if paired with deteriorating operations. Governance risk appears low; the filer certifies no undisclosed negative information. Investors should simply watch for accelerating volumes or additional insiders following suit.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, including the documents incorporated by reference herein, may contain or incorporate “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934. Forward-looking statements discuss matters that are not historical facts. Because they discuss future events or conditions, forward-looking statements may include words such as “anticipate,” “believe,” “estimate,” “intend,” “could,” “should,” “would,” “may,” “seek,” “plan,” “might,” “will,” “expect,” “anticipate,” “predict,” “project,” “forecast,” “potential,” “continue” negatives thereof or similar expressions. Forward-looking statements speak only as of the date they are made, are based on various underlying assumptions and current expectations about the future and are not guarantees. Such statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, level of activity, performance or achievement to be materially different from the results of operations or plans expressed or implied by such forward-looking statements.

We cannot predict all the risks and uncertainties. Accordingly, such information should not be regarded as representations that the results or conditions described in such statements or that our objectives and plans will be achieved, and we do not assume any responsibility for the accuracy or completeness of any of these forward-looking statements. These forward-looking statements are found at various places throughout this prospectus, including the documents incorporated by reference herein, and include information concerning possible or assumed future results of our operations, including statements about potential acquisition or merger targets; business strategies; future cash flows; financing plans; plans and objectives of management; any other statements regarding future acquisitions, future cash needs, future operations, business plans and future financial results, and any other statements that are not historical facts.

Accordingly, forward-looking statements should be not be relied upon as a predictor of actual results. Readers are urged to carefully review and consider the various disclosures made in this report and in our other filings with the SEC that attempt to advise interested parties of the risks and factors that may affect our business. We do not undertake to update our forward-looking statements to reflect events or circumstances that may arise after the date of this prospectus, except as required by law.

AmpliTech Group, Inc.

AmpliTech Group Inc. (“AMPG,” “AmpliTech” or the “Company”), incorporated in 2010 in the state of Nevada, is the parent company of AmpliTech, Inc., and the Company’s divisions, Specialty Microwave, Spectrum Semiconductor Materials, AmpliTech Group MMIC Design Center (“AGMDC”) and AmpliTech Group True G Speed Services (“AGTGSS”).

AmpliTech, Inc. designs, engineers and assembles micro-wave component-based amplifiers that meet individual customer specifications. Our products consist of Radio Frequency (“RF”) amplifiers and related subsystems, operating at multiple frequencies from 50kHz to 44GHz, including low noise amplifiers (“LNA”), medium power amplifiers, cryogenic amplifiers, and custom assembly designs for the global satellite communications, telecom (5G & IoT), space, defense, and quantum computing markets. We also offer non-recurring engineering services on a project-by-project basis, for a predetermined fixed contractual amount, or on a time plus material basis. We have both domestic and international customers in such industries as aerospace, governmental, defense and commercial satellite.

Specialty Microwave designs and manufactures state-of- the-art precision SATCOM microwave components, RF subsystems and specialized electronic assemblies for the military and commercial markets, flexible and rugged waveguides, wave guide adapters and more.

3

On December 15, 2021, we acquired substantially all of the assets of Spectrum Semiconductor Materials Inc. (“SSM”), a globally authorized distributor of integrated circuit (IC) packaging and lids for semiconductor device assembly, prototyping, testing, and production requirements founded in 1990 and headquartered in San Jose, CA.

In 2021, the Company opened AGMDC, a monolithic microwave integrated circuits (“MMIC”) chip design center, in Texas and has started to implement several of its proprietary amplifier designs into MMIC components. MMICs are semiconductor chips used in high-frequency communications applications. MMICs are widely desired for power amplification solutions to service emerging technologies, such as phased array antennas and quantum computing. MMICs carry a smaller footprint enabling them to be incorporated into a broader array of systems while reducing costs. AGMDC designs, develops and manufactures state-of-the-art signal processing components for satellite and 5G communications networks, defense, space and other commercial applications, allowing the Company to market its products to wider base of customers requiring high technology in smaller packages.

In August 2022, we formed our AGTGSS division to enable “true G speeds” to the industry. AGTGSS’ main function will be to plan and configure 5G radio systems and make them O-RAN compliant. AGTGSS will implement AmpliTech’s low noise amplifier devices in these systems to promote greater coverage, longer range and faster speeds.

On March 26, 2025, we entered into an asset purchase agreement, as amended by that certain amendment dated April 15, 2025, with Titan Crest, LLC, a Delaware limited liability company (“Titan”), and its affiliate, to purchase certain assets including intellectual property used in developing, manufacturing, marketing and selling products that use radio frequency technology (“5G ORAN radio products).

Our mission is to patent our proprietary IP and trade secrets that were used in small volume niche markets and expand our capabilities through strategic partnerships, joint ventures, mergers/acquisitions with key industry leaders in the 5G/6G, quantum computing, and cybersecurity markets. We believe this will enable us to scale up our products and revenue by developing full systems and subsystems with our unique technology as a core component, which we expect will position us as a global leader in these rapidly emerging technology sectors and addresses large volume markets as well, such as cellphone handsets, laptops, server networks, and many other applications that improve everyday quality of life.

The Company’s research and development initiative to expand its product line of low noise amplifiers to include its new 5G and wireless infrastructure products, cryogenic amplifiers and MMIC designs is progressing significantly. Our combined engineering and manufacturing resources are expected to complement the development of new subsystems for satellite, wireless, and 5G infrastructures, as well as advanced military and commercial markets.

Our Corporate History and Structure

AmpliTech Group Inc. was incorporated under the laws of the State of Nevada on December 30, 2010. On August 13, 2012, the Company acquired AmpliTech Inc., by issuing 833,750 shares of the Company’s common stock to the shareholders of AmpliTech Inc. in exchange for 100% of the outstanding shares of AmpliTech Inc. (the “Share Exchange”). After the Share Exchange, the selling shareholders owned 60,000 shares of the outstanding 893,750 shares of Company common stock, resulting in a change in control. Accordingly, the transaction was accounted for as a reverse acquisition in which AmpliTech, Inc. was deemed to be the accounting acquirer, and the operations of the Company were consolidated for accounting purposes.

AmpliTech designs, engineers and assembles microwave component based low noise amplifiers (“LNA”) that meet individual customer specifications. Application of the Company’s proprietary technology results in maximum frequency gain with minimal background noise distortion as required by each customer. The Company has both domestic and international customers in such industries as aerospace, governmental, defense and commercial satellite.

On September 12, 2019, AmpliTech Group Inc. acquired substantially all of the assets of Specialty Microwave Corporation, a privately held company based in Ronkonkoma, NY. The purchase included all inventory, orders, customers, property and equipment, and goodwill. Following the closing of the asset purchase, we hired all eight team members of SMW. In connection with the acquisition, the Company began using the trade name “Specialty Microwave”. Specialty designs and manufactures passive microwave components and related subsystems that meet individual customer specifications for both domestic and international customers for use in satellite communication ground networks.

On February 17, 2021, AmpliTech Group Inc.’s common stock and warrants commenced trading on NASDAQ under the symbols “AMPG” and “AMPGW,” respectively. A reverse split of the outstanding common stock at a 1-for-20 ratio became effective February 17, 2021, as of 12:01 a.m., Eastern Time. All share amounts have been retroactively re-stated to reflect the reverse split.

On November 19, 2021, AmpliTech Group, Inc. entered into an Asset Purchase Agreement with SSM, pursuant to which AmpliTech would acquire substantially all of the assets of SSM. SSM, located in Silicon Valley (San Jose, CA), was a global authorized distributor of IC packaging and lids for semiconductor device assembly, prototyping, testing, and production requirements. The acquisition was completed on December 15, 2021.

In 2021, the Company opened a MMIC chip design center in Texas and has started to implement several of its proprietary amplifier designs into MMIC components. MMICs are semiconductor chips used in high-frequency communications applications. MMICs are widely desired for power amplification solutions to service emerging technologies, such as phased array antennas and quantum computing. MMICs carry a smaller footprint enabling them to be incorporated into a broader array of systems while reducing costs. AGMDC designs, develops and manufactures state-of-the-art signal processing components for satellite and 5G communications networks, defense, space and other commercial applications, allowing the Company to market its products to a wider base of customers requiring high technology in smaller packages.

In August 2022, our AGTGSS division was founded to serve and provide complete system integration and ORAN compliant O-RU’s (Radio Units) for telcos, enabling the industry to access ‘True 5G Speeds’. AGTGSS provides Managed Services, Cyber Security, Cloud Services, Data Sciences and Telco Cloud Services. AGTGSS will also be providing full installation of Private 5G Networks (P5G), which includes the deployment of AmpliTech Group developed radio units. AGTGSS will implement AmpliTech’s low noise amplifier devices in these systems to promote greater coverage, longer range and faster speeds.

On March 26, 2025, we entered into an asset purchase agreement, as amended by that certain amendment dated April 15, 2025, with Titan, and its affiliate, to purchase certain assets including intellectual property used in developing, manufacturing, marketing and selling products that use radio frequency technology (“5G ORAN radio products). The aggregate purchase price for the assets is $8,000,000, which consists of $4,000,000 in cash and $4,000,000 in restricted shares of common stock of which the first $3,500,000 in cash was paid and $1,500,000 in restricted common stock was issued on April 24, 2025. The remaining $500,000 in cash to be paid and $2,500,000 in shares of restricted common stock will be issued to Titan upon the transfer of the 5G ORAN radio products’ technology and intellectual property rights by Titan to the Company. The second milestone is expected to be achieved towards the end of the year 2025.

Implications of Being a Smaller Reporting Company

We are a “smaller reporting company” meaning that the market value of our common stock held by non-affiliates is less than $250.0 million measured on the last business day of our most recent second fiscal quarter or our annual revenue is less than $100.0 million during the most recent completed fiscal year and the market value of our common stock held by non-affiliates is less than $700.0 million measured on the last business day of our most recent second fiscal quarter. Accordingly, we may provide less public disclosure than larger public companies, including the inclusion of only two years of audited financial statements and only two years of management’s discussion and analysis of financial condition and results of operations disclosure. As a result, the information that we provide to our stockholders may be different than what you might receive from other public reporting companies in which you hold equity interests.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making an investment decision, you should carefully consider any risk factors set forth in the applicable prospectus supplement and in the documents incorporated by reference in this prospectus. See “Where You Can Find More Information” and “Information We Incorporate By Reference.” Each of the risks described in these documents could materially and adversely affect our business, financial condition, results of operations and prospects, and could result in a partial or complete loss of your investment. Additional risks and uncertainties not presently known to us, or that we currently deem immaterial, may also adversely affect our business. In addition, past financial performance may not be a reliable indicator of future performance and historical trends should not be used to anticipate results or trends in future periods. This prospectus and the documents incorporated herein by reference also contain forward-looking statements that involve risks and uncertainties. Actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks described in the documents incorporated herein by reference.

Our authorized capital stock consists of 500,000,000 shares of common stock, $0.001 par value per share, and 1,000,000 shares of blank check preferred stock, $0.001 par value per share. As of July 22, 2025, there are 20,573,595 shares of common stock and no shares of preferred stock outstanding.

Common Stock

Holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders, and do not have cumulative voting rights. Subject to preferences that may be applicable to any outstanding shares of preferred stock, holders of common stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by our Board of Directors out of funds legally available for dividend payments. All outstanding shares of common stock are fully paid and non-assessable, and the shares of common stock to be issued upon completion of this offering will be fully paid and non-assessable. The holders of common stock have no preferences or rights of cumulative voting, conversion, or pre-emptive or other subscription rights. There is no redemption or sinking fund provisions applicable to the common stock. In the event of any liquidation, dissolution or winding up of our affairs, holders of common stock will be entitled to share ratably in any of our assets remaining after payment or provision for payment of all of our debts and obligations and after liquidation payments to holders of outstanding shares of preferred stock, if any.

Preferred Stock

The Board generally will be authorized, without further stockholder approval, to issue from time to time up to an aggregate of 1,000,000 shares of preferred stock, in one or more series. Each series of preferred stock will have the number of shares, designations, preferences, voting powers (or special, preferential or no voting powers), relative, participating, optional or other special rights and privileges and such qualifications, limitations or restrictions as is determined by the Board, which may include, among others, the right to provide that the shares of each such series may be: (i) subject to redemption at such time or times and at such price or prices; (ii) entitled to receive dividends (which may be cumulative or non-cumulative) at such rates, on such conditions, and at such times, and payable in preference to, or in such relation to, the dividends payable on any other class or classes or any other series; (iii) entitled to such rights upon the dissolution of, or upon any distribution of the assets of, the Company; (iv) convertible into, or exchangeable for, shares of any other class or classes of stock, or of any other series of the same or any other class or classes of stock of the Company at such price or prices or at such rates of exchange and with such adjustments, if any; or (v) entitled to the benefit of such limitations, if any, on the issuance of additional shares of such series or shares of any other series of preferred stock.

7

Our stockholders have granted the Board authority to issue the preferred stock and to determine the rights and preferences of the preferred stock in order to eliminate delays associated with a stockholder vote on specific issuances. The rights of the holders of common stock will be subordinate to the rights of holders of any preferred stock issued in the future. The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could adversely affect the voting power or other rights of the holders of common stock, and could make it more difficult for a third party to acquire, or discourage a third party from attempting to acquire, a majority of our outstanding voting stock.

We will fix the designations, voting powers, preferences and rights of the preferred stock of each series we issue under this prospectus, as well as the qualifications, limitations or restrictions thereof, in the certificate of designation relating to that series. We will file as an exhibit to the registration statement of which this prospectus is a part or will incorporate by reference from reports that we file with the SEC, the form of any certificate of designation that contains the terms of the series of preferred stock we are offering. We will describe in the applicable prospectus supplement the terms of the series of preferred stock being offered, including, to the extent applicable:

● the title and stated value;

● the number of shares we are offering;

● the liquidation preference per share;

● the purchase price;

● the dividend rate, period and payment date and method of calculation for dividends;

● whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;

● the procedures for any auction and remarketing, if applicable;

● the provisions for a sinking fund, if applicable;

● the provisions for redemption or repurchase, if applicable, and any restrictions on our ability to exercise those redemption and repurchase rights;

● any listing of the preferred stock on any securities exchange or market;

● whether the preferred stock will be convertible into our common stock, and, if applicable, the conversion price, or how it will be calculated, and the conversion period;

● whether the preferred stock will be exchangeable into debt securities, and, if applicable, the exchange price, or how it will be calculated, and the exchange period;

● voting rights of the preferred stock;

● preemptive rights, if any;

● restrictions on transfer, sale or other assignment;

● whether interests in the preferred stock will be represented by depositary shares;

● a discussion of material United States federal income tax considerations applicable to the preferred stock;

● the relative ranking and preferences of the preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs;

● any limitations on the issuance of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs; and

● any other specific terms, preferences, rights or limitations of, or restrictions on, the preferred stock.

Anti-Takeover Effects of Some Provisions of Nevada Law

The following provisions of the Nevada Revised Statutes (“NRS”) could, if applicable, have the effect of discouraging takeovers of our Company.

Transactions with Interested Stockholders. The NRS prohibits a publicly traded Nevada company from engaging in any business combination with an interested stockholder for a period of three years following the date that the stockholder became an interested stockholder unless, prior to that date, the Board of Directors of the corporation approved either the business combination itself or the transaction that resulted in the stockholder becoming an interested stockholder.

An “interested stockholder” is defined as any entity or person beneficially owning, directly or indirectly, 10% or more of the outstanding voting stock of the corporation and any entity or person affiliated with, controlling, or controlled by any of these entities or persons. The definition of “business combination” is sufficiently broad to cover virtually any type of transaction that would allow a potential acquirer to use the corporation’s assets to finance the acquisition or otherwise benefit its own interests rather than the interests of the corporation and its stockholders.

In addition, business combinations that are not approved and therefore take place after the three year waiting period may also be prohibited unless approved by the board of directors and stockholders or the price to be paid by the interested stockholder is equal to the highest of (i) the highest price per share paid by the interested stockholder within the 3 years immediately preceding the date of the announcement of the business combination or in the transaction in which he or she became an interested stockholder, whichever is higher; (ii) the market value per common share on the date of announcement of the business combination or the date the interested stockholder acquired the shares, whichever is higher; or (iii) if higher for the holders of preferred stock, the highest liquidation value of the preferred stock.

Acquisition of a Controlling Interest. The NRS contains provisions governing the acquisition of a “controlling interest” and provides generally that any person that acquires 20% or more of the outstanding voting shares of an “issuing corporation,” defined as Nevada corporation that has 200 or more stockholders at least 100 of whom are Nevada residents (as set forth in the corporation’s stock ledger); and does business in Nevada directly or through an affiliated corporation, may be denied voting rights with respect to the acquired shares, unless a majority of the disinterested stockholder of the corporation elects to restore such voting rights in whole or in part.

The statute focuses on the acquisition of a “controlling interest” defined as the ownership of outstanding shares sufficient, but for the control share law, to enable the acquiring person, directly or indirectly and individually or in association with others, to exercise (i) one-fifth or more, but less than one-third; (ii) one-third or more, but less than a majority; or (iii) a majority or more of the voting power of the corporation in the election of directors.

The question of whether or not to confer voting rights may only be considered once by the stockholders and once a decision is made, it cannot be revisited. In addition, unless a corporation’s articles of incorporation or bylaws provide otherwise (i) acquired voting securities are redeemable in whole or in part by the issuing corporation at the average price paid for the securities within 30 days if the acquiring person has not given a timely information statement to the issuing corporation or if the stockholders vote not to grant voting rights to the acquiring person’s securities; and (ii) if voting rights are granted to the acquiring person, then any stockholder who voted against the grant of voting rights may demand purchase from the issuing corporation, at fair value, of all or any portion of their securities.

The provisions of this section do not apply to acquisitions made pursuant to the laws of descent and distribution, the enforcement of a judgment, or the satisfaction of a security interest, or acquisitions made in connection with certain mergers or reorganizations.

DESCRIPTION OF WARRANTS

The following is a general description of the terms of the warrants we may issue from time to time. Particular terms of any warrants we offer will be described in the prospectus supplement relating to such warrants, as well as any warrant agreement that contains the terms of the warrants. We urge you to read the applicable prospectus supplements related to the warrants that we may sell under this prospectus, as well as the complete warrant agreements that will contain the terms of any warrants.

We may issue warrants to purchase shares of our common stock or preferred stock. Such warrants may be issued in one or more series, independently or together with shares of common stock or preferred stock or other equity or debt securities and may be attached or separate from such securities. The warrants may also be in the form of pre-funded warrants. The terms of any warrants offered under a prospectus supplement may differ from the terms described below. We may issue warrants directly or under a separate warrant agreement to be entered into between us and a warrant agent. We will name any warrant agent in the applicable prospectus supplement. Any warrant agent will act solely as our agent in connection with the warrants of a particular series and will not assume any obligation or relationship of agency or trust for or with holders or beneficial owners of warrants.

The applicable prospectus supplement and the applicable warrant agreement will describe the particular terms of any series of warrants we may issue, including the following:

	●	the title of such warrants;
	●	the aggregate number of such warrants offered;
	●	the price or prices at which such warrants will be issued;
	●	if applicable, the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each such security or each principal amount of such security;
	●	in the case of warrants to purchase debt securities, the principal amount of debt securities purchasable upon exercise of one warrant and the price at, and currency in which, this principal amount of debt securities may be purchased upon such exercise;
	●	in the case of warrants to purchase common stock or preferred stock, the number of shares of common stock or preferred stock, as the case may be, purchasable upon the exercise of one warrant and the price at which these shares may be purchased upon such exercise;
	●	the date on which the right to exercise such warrants shall commence and the date on which such right will expire;
	●	whether such warrants will be issued in registered form or bearer form;
	●	if applicable, the minimum or maximum amount of such warrants which may be exercised at any one time;
	●	if applicable, the date on and after which such warrants and the related securities will be separately transferable;

10

	●	information with respect to book-entry procedures, if any;
	●	the terms of the securities issuable upon exercise of the warrants;
	●	the anti-dilution provisions of the warrants, if any;
	●	any redemption or call provisions;
	●	if applicable, a discussion of certain federal United States income tax considerations; and
	●	any other terms of such warrants, including terms, procedures and limitations relating to the exchange and exercise of such warrants.

We and the warrant agent, if any, may amend or supplement the warrant agreement for a series of warrants without the consent of the holders of the warrants issued thereunder to effect changes that are not inconsistent with the provisions of the warrants and that do not materially and adversely affect the interests of the holders of the warrants.

Prior to exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including the right to receive distributions or dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise any voting rights.

DESCRIPTION OF RIGHTS

The following description, together with the additional information we include in any applicable prospectus supplement, summarizes the general features of the rights that we may offer under this prospectus. We may issue rights to our stockholders to purchase shares of our common stock and/or any of the other securities offered hereby. Each series of rights will be issued under a separate rights agreement to be entered into between us and a bank or trust company, as rights agent. When we issue rights, we will provide the specific terms of the rights and the applicable rights agreement in a prospectus supplement. Because the terms of any rights we offer under a prospectus supplement may differ from the terms we describe below, you should rely solely on information in the applicable prospectus supplement if that summary is different from the summary in this prospectus. We will incorporate by reference into the registration statement of which this prospectus is a part the form of rights agreement that describes the terms of the series of rights we are offering before the issuance of the related series of rights. The applicable prospectus supplement relating to any rights will describe the terms of the offered rights, including, where applicable, the following:

	●	the date for determining the persons entitled to participate in the rights distribution;
	●	the exercise price for the rights;
	●	the aggregate number or amount of underlying securities purchasable upon exercise of the rights;
	●	the number of rights issued to each stockholder and the number of rights outstanding, if any;
	●	the extent to which the rights are transferable;
	●	any conditions to completing the rights offering;
	●	the date on which the right to exercise the rights will commence and the date on which the right will expire;
	●	the extent to which the rights include an over-subscription privilege with respect to unsubscribed securities;
	●	anti-dilution provisions of the rights, if any; and
	●	any other terms of the rights, including terms, procedures and limitations relating to the distribution, exchange and exercise of the rights.

11

Holders may exercise rights as described in the applicable prospectus supplement. Upon receipt of payment and the rights certificate properly completed and duly executed at the corporate trust office of the rights agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the securities purchasable upon exercise of the rights. If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting arrangements, as described in the applicable prospectus supplement.

DESCRIPTION OF UNITS

We may issue units comprising two or more securities described in this prospectus in any combination. For example, we might issue units consisting of a combination of common stock, preferred stock, warrants to purchase common stock or any combination of such securities. The following description sets forth certain general terms and provisions of the units that we may offer pursuant to this prospectus. The particular terms of the units and the extent, if any, to which the general terms and provisions may apply to the units offered will be described in the applicable prospectus supplement.

Each unit will be issued so that the holder of the unit also is the holder of each security included in the unit. Thus, the unit will have the rights and obligations of a holder of each included security. Units will be issued pursuant to the terms of an agreement, which may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date. A copy of the forms of such agreement and the unit certificate, if applicable, relating to any particular issue of units will be filed with the SEC each time we issue units, and you should read those documents for provisions that may be important to you. For more information on how you can obtain copies of the forms of the unit agreement and the related unit certificate, see “Where You Can Find More Information.”

The prospectus supplement relating to any particular issuance of units will describe the terms of those units, including, to the extent applicable, the following:

	●	the designation and terms of the units and the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;
	●	any provision for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and
	●	whether the units will be issued in fully registered or global form.

12

PLAN OF DISTRIBUTION

We may sell the securities from time to time, by a variety of methods, including the following:

	●	on any national securities exchange or quotation service on which our securities may be listed at the time of sale, including Nasdaq;
	●	in the over-the-counter market;
	●	in transactions otherwise than on such exchange or in the over-the-counter market, which may include privately negotiated transactions and sales directly to one or more purchasers;
	●	through ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
	●	through purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
	●	through underwriters, broker-dealers, agents, in privately negotiated transactions, or any combination of these methods;
	●	through short sales;
	●	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
	●	a combination of any of these methods; or
	●	by any other method permitted pursuant to applicable law.

The securities may be distributed from time to time in one or more transactions:

	●	at a fixed price or prices, which may be changed;
	●	at market prices prevailing at the time of sale;
	●	at prices related to such prevailing market prices; or
	●	at negotiated prices.

A prospectus supplement or supplements (and any related free writing prospectus that we may authorize to be provided to you) will describe the terms of the offering of the securities, including, to the extent applicable:

	●	the name or names of the underwriters, dealers or agents, if any;
	●	the purchase price of the securities or other consideration therefor, and the proceeds, if any, we will receive from the sale;
	●	any over-allotment or other options under which underwriters may purchase additional securities from us;
	●	any agency fees or underwriting discounts and other items constituting agents’ or underwriters’ compensation;
	●	any public offering price;
	●	any discounts or concessions allowed or reallowed or paid to dealers; and
	●	any securities exchange or market on which the securities may be listed.

Offers to purchase the securities being offered by this prospectus may be solicited directly. Agents may also be designated to solicit offers to purchase the securities from time to time. Any agent involved in the offer or sale of our securities will be identified in a prospectus supplement.

13

If a dealer is utilized in the sale of the securities being offered by this prospectus, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If an underwriter is utilized in the sale of the securities being offered by this prospectus, an underwriting agreement will be executed with the underwriter at the time of sale and the name of any underwriter will be provided in the prospectus supplement that the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we, or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best-efforts basis and a dealer will purchase securities as a principal and may then resell the securities at varying prices to be determined by the dealer.

Any compensation paid to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers will be provided in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc., or FINRA, the maximum amount of underwriting compensation, including underwriting discounts and commissions, to be paid in connection with any offering of securities pursuant to this prospectus may not exceed 8% of the aggregate principal amount of securities offered. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain expenses. The securities may or may not be listed on a national securities exchange. To facilitate the offering of 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 involve the sale by persons participating in the offering of more securities than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. 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.

If indicated in the applicable prospectus supplement, underwriters or other persons acting as agents may be authorized to solicit offers by institutions or other suitable purchasers to purchase the securities at the public offering price set forth in the prospectus supplement, pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the prospectus supplement. These purchasers may include, among others, commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions. Delayed delivery contracts will be subject to the condition that the purchase of the securities covered by the delayed delivery contracts will not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which the purchaser is subject. The underwriters and agents will not have any responsibility with respect to the validity or performance of these contracts.

We may engage in at-the-market offerings into an existing trading market in accordance with rule 415(a)(4) under the Securities Act. In addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us, or borrowed from us or others to settle those sales or to close out any related open borrowings of common stock and may use securities received from us in settlement of those derivatives to close out any related open borrowings of our common stock. In addition, we may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

14

The underwriters, dealers and agents may engage in transactions with us, or provide services for us, in the ordinary course of business for which they receive compensation.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION

FOR SECURITIES ACT LIABILITIES

Nevada law provides that a Nevada corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation (i.e., a “non-derivative proceeding”), by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with the action, suit or proceeding if he or she:

● Is not liable under Section 78.138 of the Nevada Revised Statutes for breach of his or her fiduciary duties to the corporation; or

● Acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

In addition, a Nevada corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor (i.e., a “derivative proceeding”), by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses, including amounts paid in settlement and attorneys’ fees actually and reasonably incurred by him or her in connection with the defense or settlement of the action or suit if he:

● Is not liable under Section 78.138 of the Nevada Revised Statute for breach of his or her fiduciary duties to the corporation; or

● Acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation.

Under Nevada law, indemnification may not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any non-derivative proceeding or any derivative proceeding, or in defense of any claim, issue or matter therein, the corporation is obligated to indemnify him or her against expenses, including attorneys’ fees, actually and reasonably incurred in connection with the defense.

Further, Nevada law permits a Nevada corporation to purchase and maintain insurance or to make other financial arrangements on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise for any liability asserted against him or her and liability and expenses incurred by him or her in his or her capacity as a director, officer, employee or agent, or arising out of his or her status as such, whether or not the corporation has the authority to indemnify him or her against such liability and expenses.

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

SUBJECT TO COMPLETION, DATED JULY 22, 2025

PROSPECTUS SUPPLEMENT

 

AMPLITECH GROUP, INC.

Up to $3,343,000

Shares of Common Stock

We have entered into an equity distribution agreement, or the Equity Distribution Agreement, with Maxim Group LLC, or Maxim, relating to shares of our common stock offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the Equity Distribution Agreement, we may offer and sell shares of our common stock, par value $0.001, having an aggregate offering price of up to $3,343,000 from time to time through Maxim, acting as our exclusive sales agent, at our discretion.

Our common stock and warrants are listed on the Nasdaq Capital Market and trade under the symbols “AMPG” and “AMPGW” respectively. The last reported sale price of our Common Stock on the Nasdaq Capital Market on July 18, 2025, was $2.86 per share. We are a “smaller reporting company” as defined under the federal securities laws and, as such, have elected to comply with certain reduced reporting requirements for this prospectus supplement and may elect to do so in future filings.

As of the date of this prospectus supplement, the aggregate market value of our outstanding common stock held by non-affiliates is approximately $51,516,230 which is calculated based on 20,573,595 shares of outstanding common stock, of which 17,582,331 shares are held by non-affiliates, and a per share price of $2.93, which was the closing price of our common stock on July 17, 2025, which is the highest closing sale price of our common stock on Nasdaq Capital Market within the prior sixty (60) days of the filing a registration statement of which this prospectus supplement is a part. During the prior twelve calendar month period that ends on and includes the date hereof, the Company sold an aggregate of $13,827,802 shares of common stock pursuant to General Instruction I.B.6 to Form S-3.

Sales of our common stock, if any, under this prospectus supplement and accompanying prospectus may be made in sales deemed to be “at the market offerings” as defined in rule 415 promulgated under the Securities Act of 1933, as amended, or the Securities Act. Maxim is not required to sell any specific number or dollar amount of securities but will act as a sales agent using commercially reasonable efforts consistent with its normal trading and sales practices, on mutually agreed terms between Maxim and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

The compensation to Maxim for sales of common stock sold pursuant to the Equity Distribution Agreement will be an amount equal to 3.0% of the gross proceeds of any shares of common stock sold under the Equity Distribution Agreement. In connection with the sale of the common stock on our behalf, Maxim will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of Maxim will be deemed to be underwriting commissions or discounts. We have also agreed to provide indemnification and contribution to Maxim with respect to certain liabilities, including liabilities under the Securities Act or the Exchange Act of 1934, as amended, or the Exchange Act.

Investing in our securities involves a high degree of risk. Before buying any of our securities, you should carefully read “Risk Factors” on page S-8 of this prospectus supplement, and under similar headings in the other documents that are incorporated by reference into this prospectus supplement and the accompanying prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

PROSPECTUS SUPPLEMENT SUMMARY

This summary contains basic information about us and this offering. Because it is a summary, it does not contain all of the information that you should consider before deciding to invest in our securities. Before you decide to invest in our securities, you should read this entire prospectus supplement and the accompanying prospectus carefully, any related free writing prospectus that we have authorized for use in connection with the offering and the documents incorporated by reference herein, including the information under the heading “Risk Factors.”

Overview

AmpliTech Group Inc. (“AMPG,” “AmpliTech” or the “Company”), incorporated in 2010 in the state of Nevada, is the parent company of AmpliTech, Inc., and the Company’s divisions, Specialty Microwave, Spectrum Semiconductor Materials, AmpliTech Group MMIC Design Center (“AGMDC”) and AmpliTech Group True G Speed Services (“AGTGSS”).

AmpliTech, Inc. designs, engineers and assembles micro-wave component-based amplifiers that meet individual customer specifications. Our products consist of Radio Frequency (“RF”) amplifiers and related subsystems, operating at multiple frequencies from 50kHz to 44GHz, including low noise amplifiers (“LNA”), medium power amplifiers, cryogenic amplifiers, and custom assembly designs for the global satellite communications, telecom (5G & IoT), space, defense, and quantum computing markets. We also offer non-recurring engineering services on a project-by-project basis, for a predetermined fixed contractual amount, or on a time plus material basis. We have both domestic and international customers in such industries as aerospace, governmental, defense and commercial satellite.

Specialty Microwave designs and manufactures state-of- the-art precision SATCOM microwave components, RF subsystems and specialized electronic assemblies for the military and commercial markets, flexible and rugged waveguides, wave guide adapters and more.

On December 15, 2021, we acquired substantially all of the assets of Spectrum Semiconductor Materials Inc. (“SSM”), a globally authorized distributor of integrated circuit (IC) packaging and lids for semiconductor device assembly, prototyping, testing, and production requirements founded in 1990 and headquartered in San Jose, CA.

In 2021, the Company opened AGMDC, a monolithic microwave integrated circuits (“MMIC”) chip design center, in Texas and has started to implement several of its proprietary amplifier designs into MMIC components. MMICs are semiconductor chips used in high-frequency communications applications. MMICs are widely desired for power amplification solutions to service emerging technologies, such as phased array antennas and quantum computing. MMICs carry a smaller footprint enabling them to be incorporated into a broader array of systems while reducing costs. AGMDC designs, develops and manufactures state-of-the-art signal processing components for satellite and 5G communications networks, defense, space and other commercial applications, allowing the Company to market its products to wider base of customers requiring high technology in smaller packages.

In August 2022, we formed our AGTGSS division to enable “true G speeds” to the industry. AGTGSS’ main function will be to plan and configure 5G radio systems and make them O-RAN compliant. AGTGSS will implement AmpliTech’s low noise amplifier devices in these systems to promote greater coverage, longer range and faster speeds.

On March 26, 2025, we entered into an asset purchase agreement, Titan Crest, LLC, a Delaware limited liability company (“Titan”), and its affiliate, to purchase certain assets including intellectual property used in developing, manufacturing, marketing and selling products that use radio frequency technology (“5G ORAN radio products).

Our mission is to patent our proprietary IP and trade secrets that were used in small volume niche markets and expand our capabilities through strategic partnerships, joint ventures, mergers/acquisitions with key industry leaders in the 5G/6G, quantum computing, and cybersecurity markets. We believe this will enable us to scale up our products and revenue by developing full systems and subsystems with our unique technology as a core component, which we expect will position us as a global leader in these rapidly emerging technology sectors and addresses large volume markets as well, such as cellphone handsets, laptops, server networks, and many other applications that improve everyday quality of life.

S-4

The Company’s research and development initiative to expand its product line of low noise amplifiers to include its new 5G and wireless infrastructure products, cryogenic amplifiers and MMIC designs is progressing significantly. Our combined engineering and manufacturing resources are expected to complement the development of new subsystems for satellite, wireless, and 5G infrastructures, as well as advanced military and commercial markets.

Our Corporate History and Structure

AmpliTech Group Inc. was incorporated under the laws of the State of Nevada on December 30, 2010. On August 13, 2012, the Company acquired AmpliTech Inc., by issuing 833,750 shares of the Company’s common stock to the shareholders of AmpliTech Inc. in exchange for 100% of the outstanding shares of AmpliTech Inc. (the “Share Exchange”). After the Share Exchange, the selling shareholders owned 60,000 shares of the outstanding 893,750 shares of Company common stock, resulting in a change in control. Accordingly, the transaction was accounted for as a reverse acquisition in which AmpliTech, Inc. was deemed to be the accounting acquirer, and the operations of the Company were consolidated for accounting purposes.

AmpliTech designs, engineers and assembles microwave component based low noise amplifiers (“LNA”) that meet individual customer specifications. Application of the Company’s proprietary technology results in maximum frequency gain with minimal background noise distortion as required by each customer. The Company has both domestic and international customers in such industries as aerospace, governmental, defense and commercial satellite.

On September 12, 2019, AmpliTech Group Inc. acquired substantially all of the assets of Specialty Microwave Corporation, a privately held company based in Ronkonkoma, NY. The purchase included all inventory, orders, customers, property and equipment, and goodwill. Following the closing of the asset purchase, we hired all eight team members of SMW. In connection with the acquisition, the Company began using the trade name “Specialty Microwave”. Specialty designs and manufactures passive microwave components and related subsystems that meet individual customer specifications for both domestic and international customers for use in satellite communication ground networks.

On February 17, 2021, AmpliTech Group Inc.’s common stock and warrants commenced trading on NASDAQ under the symbols “AMPG” and “AMPGW,” respectively. A reverse split of the outstanding common stock at a 1-for-20 ratio became effective February 17, 2021, as of 12:01 a.m., Eastern Time. All share amounts have been retroactively re-stated to reflect the reverse split.

On November 19, 2021, AmpliTech Group, Inc. entered into an Asset Purchase Agreement with SSM, pursuant to which AmpliTech would acquire substantially all of the assets of SSM. SSM, located in Silicon Valley (San Jose, CA), was a global authorized distributor of IC packaging and lids for semiconductor device assembly, prototyping, testing, and production requirements. The acquisition was completed on December 15, 2021.

In 2021, the Company opened a MMIC chip design center in Texas and has started to implement several of its proprietary amplifier designs into MMIC components. MMICs are semiconductor chips used in high-frequency communications applications. MMICs are widely desired for power amplification solutions to service emerging technologies, such as phased array antennas and quantum computing. MMICs carry a smaller footprint enabling them to be incorporated into a broader array of systems while reducing costs. AGMDC designs, develops and manufactures state-of-the-art signal processing components for satellite and 5G communications networks, defense, space and other commercial applications, allowing the Company to market its products to a wider base of customers requiring high technology in smaller packages.

In August 2022, our AGTGSS division was founded to serve and provide complete system integration and ORAN compliant O-RU’s (Radio Units) for telcos, enabling the industry to access ‘True 5G Speeds’. AGTGSS provides Managed Services, Cyber Security, Cloud Services, Data Sciences and Telco Cloud Services. AGTGSS will also be providing full installation of Private 5G Networks (P5G) which includes the deployment of AmpliTech Group developed radio units. AGTGSS will implement AmpliTech’s low noise amplifier devices in these systems to promote greater coverage, longer range and faster speeds.

S-5

On March 26, 2025, we entered into an asset purchase agreement, as amended by that certain amendment dated April 15, 2025, with Titan, and its affiliate (as amended, the “Titan APA”) to purchase certain assets including intellectual property used in developing, manufacturing, marketing and selling products that use radio frequency technology (“5G ORAN radio products). The aggregate purchase price for the assets is $8,000,000, which consists of $4,000,000 in cash and $4,000,000 in restricted shares of common stock of which the first $3,500,000 in cash was paid and $1,500,000 in restricted common stock was issued on April 24, 2025. The remaining $500,000 in cash to be paid and $2,500,000 in shares of restricted common stock will be issued to Titan upon the transfer of the 5G ORAN radio products’ technology and intellectual property rights by Titan to the Company. The second milestone is expected to be achieved towards the end of the year 2025.

Implications of Being a Smaller Reporting Company

We are a “smaller reporting company” meaning that the market value of our common stock held by non-affiliates is less than $250.0 million measured on the last business day of our most recent second fiscal quarter or our annual revenue is less than $100.0 million during the most recent completed fiscal year and the market value of our common stock held by non-affiliates is less than $700.0 million measured on the last business day of our most recent second fiscal quarter. Accordingly, we may provide less public disclosure than larger public companies, including the inclusion of only two years of audited financial statements and only two years of management discussion and analysis of financial condition and results of operations disclosure. As a result, the information that we provide to our stockholders may be different than what you might receive from other public reporting companies in which you hold equity interests.

S-7

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risks described below and all of the information contained or incorporated by reference in this prospectus supplement, including the risk factors described in our Annual Report on Form 10-K for the year ended December 31, 2024, Quarterly Reports on Form 10-Q for the period ended March 31, 2025 and any subsequent periodic report that we may file with the SEC, and all other information contained or incorporated by reference into this prospectus supplement and the accompanying prospectus before deciding whether to purchase the securities offered hereby. Our business, financial condition, results of operations and prospects could be materially and adversely affected by these risks.

Risks Related to This Offering

If our business developments and achievements do not meet the expectations of investors or securities analysts or for other reasons the expected benefits do not occur, the market price of shares of our Common Stock traded on Nasdaq may decline.

If our business developments and achievements do not meet the expectations of investors or securities analysts, the market price of shares of our Common Stock traded on Nasdaq may decline. The trading price of shares of our Common Stock could be volatile and subject to wide fluctuations in response to various factors, some of which are beyond our control. Any of the factors mentioned in this “Risk Factors” section and elsewhere in this prospectus could have a negative impact on your investment in our securities and our securities may trade at prices significantly below the price you paid for them. In such circumstances, the trading price of our securities may not recover and may experience a further decline.

The price of shares of our Common Stock has fluctuated substantially.

The price of shares of our Common Stock has fluctuated substantially. Therefore, some investors who have purchased our Common Stock at high prices face the risk of losing a significant portion of their original investment if they have to sell at a time when the price of shares of our Common Stock has declined.

For example, during the fourth quarter of 2024, and in particular the months of November and December 2024, the price of our Common Stock and trading volume significantly increased. During this period, we did not make any significant announcements other than our financial condition and results of operations for the three and nine months ended September 30, 2024. Accordingly, the market price of our Common Stock may fluctuate dramatically and may decline rapidly after you purchase shares in this offering, irrespective of any developments in our business. In addition, the volatility of our stock price could cause other consequences including causing a short squeeze due to the difference in investment decisions by short sellers of our Common Stock shares and buy-and-hold decisions of longer investors.

You should consider an investment in our securities to be risky, and you should invest in our securities only if you can withstand a significant loss and wide fluctuations in the market value of your investment. Some factors that may cause the market price of shares of our Common Stock to fluctuate, in addition to the other risks mentioned in this “Risk Factors” section and elsewhere in this prospectus, are:

	●	sale of shares of our Common Stock by our stockholders;
	●	volatility in trading volumes of our shares of Common Stock;
	●	our ability to obtain financings to conduct and complete our business activities;
	●	possible delays in the expected recognition of revenue due to lengthy and sometimes unpredictable sales timelines;
	●	failures to meet external expectations or management guidance;
	●	changes in our capital structure and future issuances of securities;
	●	our cash position;
	●	announcements and events surrounding financing efforts;
	●	changes in general economic, political and market conditions in any area in which we conduct our business;
	●	analyst research reports, recommendations and changes in recommendations, price targets, and withdrawals of coverage;

S-8

	●	quarterly variations in our results of operations or those of our competitors;
	●	delays in end-user deployments of products;
	●	our ability to develop and market new and enhanced products on a timely basis;
	●	commencement of, or our involvement in, litigation;
	●	major changes in our Board of Directors or management, including the departure of Mr. Maqbool;
	●	our failure to generate material revenues;
	●	our public disclosure of the terms of any financing which we may consummate in the future;
	●	cancellation of key contracts;
	●	short selling activities; and
	●	other events or factors, many of which may be out of our control.

In addition, if the market for stocks in our industry or industries related to our industry, or the stock market in general, experiences a loss of investor confidence, the trading price of shares of our Common Stock could decline for reasons unrelated to our business, financial condition and results of operations. If any of the foregoing occurs, it could cause our stock price to fall and may expose us to lawsuits that, even if unsuccessful, could be costly to defend and a distraction to management.

Our management will have broad discretion over the use of the net proceeds from this offering, you may not agree with how we use the proceeds, and the proceeds may not be invested successfully.

Our management will have broad discretion as to the use of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of commencement of this offering. Accordingly, you will be relying on the judgment of our management regarding the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that, pending their use, we may invest the net proceeds in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flows.

You will experience immediate and substantial dilution in the net tangible book value per share of the common stock you purchase.

The offering price per share in this offering may exceed the historical and pro forma as adjusted net tangible book value per share of our common stock outstanding prior to this offering. If the price per share of our common stock being offered is substantially higher than the pro forma as adjusted net tangible book value per share of our common stock, you will suffer immediate and substantial dilution in the pro forma net tangible book value of the common stock you purchase in this offering. Assuming that an aggregate of 1,168,881 shares of our common stock are sold at a price of $2.86 per share, the last reported sale price of our common stock on Nasdaq on July 18, 2025, for aggregate gross proceeds of $3,343,000 and after deducting commissions and estimated offering expenses payable by us, you would experience immediate dilution of $1.5549 per share, representing the difference between our pro forma as adjusted net tangible book value per share of common stock as of March 31, 2025. If we were to sell shares of our common stock in this offering at a price per share greater than our pro forma net tangible book value, it would result in dilution of your investment. The exercise of outstanding stock options or warrants, or issuance of shares of common stock issuable to Titan under the Titan APA or issuance of additional options under our Equity Plan would result in further dilution of your investment. See the section entitled “Dilution” below for a more detailed illustration of the dilution you may incur if you participate in this offering. Because the sales of the shares offered hereby will be made directly into the market or in negotiated transactions, the prices at which we sell these shares will vary and these variations may be significant. Purchasers of the shares we sell, as well as our existing shareholders, will experience significant dilution if we sell shares at prices significantly below the price at which they invested.

S-9

You may experience future dilution as a result of future equity offerings and other issuances of our common stock or other securities. In addition, this offering and future equity offerings and other issuances of our common stock or other securities may adversely affect our common stock price.

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price per share in this offering. We may not be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by the investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or securities convertible into common stock in future transactions may be higher or lower than the price per Share in this offering. You will incur dilution upon exercise of any outstanding stock options, warrants or upon the issuance of shares of common stock under our stock incentive programs. In addition, the sale of Shares in this offering and any future sales of a substantial number of shares of our common stock in the public market, or the perception that such sales may occur, could adversely affect the price of our common stock. We cannot predict the effect, if any, that market sales of those shares of common stock or the availability of those shares for sale will have on the market price of our common stock.

The common stock offered hereby will be sold in “at the market offering” and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares of common stock in this offering at different times will likely pay different prices and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares of common stock sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares of common stock as a result of sales of common stock made at prices lower than the prices they paid.

The actual number of shares of common stock we will issue under the Equity Distribution Agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the Equity Distribution Agreement and compliance with applicable law, we have the discretion to deliver a sales notice to Maxim at any time throughout the term of the Equity Distribution Agreement. The number of shares of common stock that are sold by Maxim after delivering a sales notice will fluctuate based on the market price of the common stock during the sales period and limits we set with Maxim. Because the price per share of each share of common stock sold will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares of common stock that will be ultimately issued.

We are subject to certain continuing listing requirements under the Nasdaq Listing Rules, if we fail to comply with The Nasdaq Capital Market continued listing requirements, our Common Stock may be delisted.

The listing of our Common Stock on The Nasdaq Capital Market is contingent upon our compliance with The Nasdaq Capital Market’s conditions for continued listing. If we fail to meet any Nasdaq listing requirements, including the minimum bid price, and do not regain compliance, we may be subject to delisting by Nasdaq. In the event our common stock is no longer listed for trading on Nasdaq, our trading volume and share price may decrease and you may have a difficult time selling your shares of common stock. In addition, we may experience difficulties in raising capital which could materially adversely affect our operations and financial results. Further, delisting from Nasdaq markets could also have other negative effects, including potential loss of confidence by partners, lenders, suppliers and employees. Finally, delisting could make it harder for you and the Company to sell the securities and hard for us to raise capital.

We have material weaknesses in our internal accounting control over financial reporting.

Our management has identified material weaknesses in our internal control over financial reporting related to lack of segregation of duties resulting from our limited personnel and ineffective control over financial statement disclosure as controls were not designed and in place to ensure that all disclosures required were originally addressed in our financial statements and has concluded that, due to such material weaknesses, our disclosure controls and procedures were not effective as of December 31, 2024.

During the three months ended March 31, 2024, we made several transactions in digital currency in the total amount of approximately $3.25 million (the “Digital Currency Investment”) which was fraudulently induced. As a result, we identified further additional material weaknesses regarding our internal controls over financial reporting including, but not limited to, the lack of segregation of duties involved in the execution and approvals of wire transfers for material investments in digital assets.

S-10

We have identified certain steps necessary to address the material weaknesses, and in the first and second quarter of 2024, we continued to implement the remedial procedures. However, if not remediated, or if we identify further material weaknesses in our internal controls, our failure to establish and maintain effective disclosure controls and procedures and internal control over financial reporting could result in material misstatements in our financial statements and a failure to meet our reporting and financial obligations, each of which could have a material adverse effect on our financial condition and the trading price of our common stock.

On October 31, 2024, the Company received a shareholder letter demanding that the Company’s Board take action against certain and/or former officers and directors of the Company asserting violations of fiduciary duties of good faith, loyalty and due care, and/or the aiding and abetting of such breaches of fiduciary duty in connection with the Digital Currency Investment. We have established a Board committee to review this letter and to prepare a response thereto. In addition, as previously discussed, the Company’s Board has taken steps and adopted procedures in response to the material weakness related to the Digital Currency Investment.

If not remediated, or if we identify further material weaknesses in our internal controls, our failure to establish and maintain effective disclosure controls and procedures and internal control over financial reporting could result in material misstatements in our financial statements and a failure to meet our reporting and financial obligations, each of which could have a material adverse effect on our financial condition and the trading price of our common stock.

There is no assurance that we will realize the anticipated benefits under the Titan APA

There can be no guarantees that the acquisition of the assets under the Titan APA will materialize into purchase orders and new customers and that we will generate the financial and strategic benefits we expected. In addition, purchase orders are subject to cancellation, modification or delays, which could negatively impact our revenues and return on investment. In addition, we may face operational challenges and unforeseen liabilities that may negatively impact our business.

We have entered into non-binding letter of intent for purchase orders and there is no assurance that we will enter into definitive purchase orders or generate revenues as expected.

On March 20, 2025, the Company entered into a non-binding letter of intent with a contract manufacturer on behalf of its end user for the purchase of $78 million of the Company’s Oran radios. There is no assurance that the letter of intent will result in a series of definitive purchase orders or generate revenues as expected. Even if we enter into definitive purchase orders, they are subject to delay, modification or cancellation, which may adversely affect our revenue and financial performance.

Potential Adverse Effect of Tariffs

During the quarter ended March 31, 2025, the U.S. government increased certain existing tariffs and implemented new tariffs on imported products. In April 2025, the U.S. government increased import tariffs across a wide range of countries at various rates, including on product imports from almost all countries, and individualized higher tariffs on certain countries, which include certain countries where the Company sources raw materials and components. As a result, selling prices of the Company’s finished products are likely to increase if tariffs continue to be enforced at current levels or are increased in the future, which may have a negative impact on the Company’s revenues and cash flows. Some of these tariff announcements have since been followed by announcements of limited exemptions and temporary pauses, however, due to the uncertainties pertaining to tariffs and tariff levels, it is difficult to for us to reliably forecast their short-term or ongoing impact to our business or that of our customers. While we are actively evaluating the potential impacts of these tariffs, as well as our ability to mitigate their related impacts, such tariffs may have a negative impact on our revenues, profitability and cash flows.

S-11

USE OF PROCEEDS

We may offer and sell shares of our common stock having aggregate sales proceeds of up to $1.0 million from time to time. The amount of proceeds we receive, if any, will depend on the actual number of shares of our common stock sold and the market price at which such shares are sold. There can be no assurance that we will be able to sell any shares or fully utilize the Equity Distribution Agreement with Maxim as a source of financing. Because there is no minimum offering amount required as a condition to close this offering, the net proceeds to us, if any, are not determinable at this time.

The precise amount and timing of the application of such net proceeds will depend upon our funding requirements and the availability and cost of other funds. Our board of directors and management will have considerable discretion in the application of the net proceeds from this offering, and it is possible that we may allocate the proceeds differently than investors in the offering may desire or that we may fail to maximize the return on these proceeds. You will be relying on the judgment of our management with regard to the use of proceeds from this offering, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately.

DIVIDEND POLICY

We have never declared or paid dividends on our common stock. We do not anticipate paying any dividends on our common stock in the foreseeable future. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business. Any future determination to declare dividends will be subject to the discretion of our Board of Directors and will depend on various factors, including applicable laws, our results of operations, financial condition, future prospects and any other factors deemed relevant by our Board of Directors.

DESCRIPTION OF SECURITIES WE ARE OFFERING

Common Stock

We are offering up to $3,343,000 shares of our common stock in this offering pursuant to this prospectus supplement and the accompanying prospectus. As of July 22, 2025, there were 20,573,595 of common stock issued and outstanding, held by approximately 46 stockholders of record. Not reflected in the number of stockholders of record are persons who beneficially own shares of common stock held in nominee or street name. See “Descriptions of Capital Stock” beginning on page 7 in the accompanying prospectus for more information regarding our shares of common stock.

DILUTION

Our net tangible book value on March 31, 2025 was approximately $28,739,597 or $1.4619 per share. “Net tangible book value” is total assets minus the sum of liabilities and intangible assets. “Net tangible book value per share” is net tangible book value divided by the total number of shares of our outstanding common stock.

After giving effect to (i) the payment of $3,500,000 and issuance of 914,635 shares of common stock at price of $1.64 per share for an aggregate amount of $1,500,000 in connection with the Titan APA, our pro forma net tangible book value as of March 31, 2025 would have been approximately $25,239,597 or $1.2268 per share.

After giving effect to the sale of 1,168,881 shares of common stock in this offering, at an assumed offering price of $2.86 per share, which was the last reported sale price of our common stock on the Nasdaq Capital Market on July 18, 2025, and after deducting Maxim fees and estimated offering expenses payable by us in connection with this offering, our pro forma as adjusted net tangible book value as of March 31, 2025 would have been approximately $28,375,143, or $1.3051 per share. This represents an immediate increase in net tangible book value of $0.0783 per share to our existing shareholders and an immediate dilution of $1.5549 per share to the investors participating in this offering.

S-12

The following table illustrates this per-share dilution of our common stock:

Assumed offering price per share						$	2.86
Net tangible book value per share as of March 31, 2025		$	1.4619
Pro forma net tangible book value per share as of March 31, 2025			1.2268
Increase to pro forma net tangible book value per share attributable to this offering			0.0783
Pro forma as adjusted net tangible book value per share after this offering						$	1.3051
Dilution per share to new investors in this offering						$	1.5549

The table above assumes for illustrative purposes that an aggregate 1,168,881 shares of our common stock are sold during the term of the Equity Distribution Agreement with Maxim at an assumed offering price of $2.86 per share, the last reported sale price of our common stock on Nasdaq Capital Market on July 18, 2025 for aggregate gross proceeds of $3,343,000. The shares subject to the Equity Distribution Agreement with Maxim are being sold from time to time at various prices.

An increase of $0.40 per share in the price at which the shares are sold from the assumed offering price of $2.86 per share shown in the table above, assuming all of our common stock in the aggregate amount of $3,343,000 during the term of the Equity Distribution Agreement with Maxim is sold at that price, would increase the dilution in pro forma as adjusted net tangible book value per share to new investors in this offering to $1.3259 per share, after deducting commissions and estimated aggregate offering expenses payable by us. A decrease of $0.40 per share in the price at which the shares are sold from the assumed offering price of $2.86 per share shown in the table above, assuming all of our common stock in the aggregate amount of $3,343,000 during the term of the Equity Distribution Agreement with Maxim is sold at that price, would decrease the dilution in pro forma as adjusted net tangible book value per share to new investors in this offering to $1.2842 per share, after deducting commissions and estimated aggregate offering expenses payable by us. This information is supplied for illustrative purposes only.

The foregoing table is based on shares of common stock outstanding as of March 31, 2025 and excludes the following:

	●	1,320,000 shares of common stock issuable upon exercise of stock options granted under the Equity Plan, which are outstanding as of March 31, 2025 and subject to vesting and of which 1,295,000 were issued at a weighted-average exercise price of $2.28 and 25,000 were issued at a weighted-average exercise price of $2.32;
	●	735,142 shares of common stock reserved for issuance under the Equity Plan; and
	●	3,296,942 shares of common stock issuable upon the exercise of the warrants outstanding as of March 31, 2025, at a weighted average exercise price of $7.83 per share.

To the extent that any of the above outstanding options or warrants are exercised or we issue additional shares under our equity incentive plans, there will be further dilution to new investors. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our shareholders.

S-13

PLAN OF DISTRIBUTION

We entered into the Equity Distribution Agreement with Maxim Group LLC (“Maxim”) on July 22, 2025. In accordance with the Equity Distribution Agreement, Maxim has agreed to act as exclusive sales agent in connection with this offering of our common stock having an aggregate offering price of up to approximately $3,343,000 pursuant to this prospectus supplement and the accompanying base prospectus. Maxim is not purchasing or selling any of the shares of our common stock offered by this prospectus supplement, nor is it required to arrange the purchase or sale of any specific number or dollar amount of shares of our common stock but has agreed to use its reasonable best efforts to arrange for the sale of all of the shares of our common stock offered hereby.

Upon delivery of a placement notice and subject to the terms and conditions of the Equity Distribution Agreement, Maxim may sell shares of our common stock by any method permitted by law deemed to be an “at-the-market” equity offering as defined in Rule 415 promulgated under the Securities Act, including sales made directly on or through the Nasdaq Capital Market, the existing trading market for our common stock, sales made to or through a market maker other than on an exchange or otherwise, in negotiated transactions at market prices prevailing at the time of sale or at prices related to such prevailing market prices, and/or any other method permitted by law, including in privately negotiated transactions.

We will pay Maxim in cash, upon each sale of shares of our common stock pursuant to the Equity Distribution Agreement, a commission equal to 3.0% of the gross proceeds from each sale of shares of our common stock. Because there is no minimum offering amount required as a condition to this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We have also agreed to reimburse Maxim for certain specified expenses, including actual reasonable and documented out-of-pocket costs and expenses, including the fees and disbursements of its legal counsel, in an amount of up to $30,000. In addition to such fees, at the end of each quarter in which the offering is open and during which sales of our common stock have occurred, we have agreed to pay Maxim’s legal counsel an additional legal fee equal to $3,000.

Settlement for sales of shares of our common stock will occur on the second business day, or such shorter settlement cycle as may be in effect under Rule 15c6-1 of the Securities Exchange Act of 1934 from time to time, following the date on which any sales are made, or on some other date that is agreed upon by us and Maxim in connection with a particular transaction, in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement. Sales of shares of our common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and Maxim may agree upon.

We have agreed to provide indemnification and contribution to Maxim and specified persons against certain civil liabilities, including liabilities under the Securities Act, and the Securities Exchange Act of 1934, as amended, or the Exchange Act, and to contribute to payments that Maxim may be required to make in respect of such liabilities.

Maxim may be deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act, and any commissions received by them and any profit realized on the resale of the shares sold by them while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. As an underwriter, Maxim would be required to comply with the requirements of the Securities Act and the Exchange Act, including, without limitation, Rule 415(a)(4) under the Securities Act and Rule 10b-5 and Regulation M under the Exchange Act. These rules and regulations may limit the timing of purchases and sales of shares by the agent acting as principal. Under these rules and regulations, Maxim:

● may not engage in any stabilization activity in connection with our securities; and

● may not bid for or purchase any of our securities or attempt to induce any person to purchase any of our securities, other than as permitted under the Exchange Act, until it has completed its participation in the distribution.

The offering of shares of our common stock pursuant to the Equity Distribution Agreement will terminate upon the earliest of (i) the sale of all common stock having an aggregate offering price of $3,343,000 as provided for in this prospectus supplement, and (iii) the termination of the Equity Distribution Agreement by the provision of five (5) days prior written notice by either party or otherwise pursuant to the terms of the Equity Distribution Agreement.

S-14

This prospectus supplement and the accompanying base prospectus in electronic format may be made available on a website maintained by Maxim and Maxim may distribute this prospectus supplement and the accompanying base prospectus electronically.

The foregoing does not purport to be a complete statement of the terms and conditions of the Equity Distribution Agreement. A copy of the Equity Distribution Agreement is included as an exhibit to our Current Report on Form 8-K that will be filed with the SEC.

Our common stock is traded on the Nasdaq Capital Market under the symbol “AMPG.”

Other than in the United States, no action has or will be taken by us or Maxim that would permit a public offering of the securities offered by this prospectus supplement in any jurisdiction where action for that purpose is required. The securities offered by this prospectus supplement may not be offered or sold, directly or indirectly, nor may this prospectus supplement or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this prospectus supplement comes are advised to inform themselves about and to observe any restrictions relating to the offering and the distribution of this prospectus supplement. This prospectus supplement does not constitute an offer to sell or a solicitation of an offer to buy any securities offered by this prospectus supplement in any jurisdiction in which such an offer or a solicitation is unlawful.

Other Relationships

From September to December 2024, we conducted multiple offerings to institutional investors pursuant to which we issued 9,886,847 shares of our common stock for gross proceeds of approximately $23,624,159 in gross proceeds, in which Maxim acted as our placement agent. Pursuant to the terms of prior placement agency agreements, we agreed to pay to Maxim a tail fee equal to 7.0% the aggregate gross proceeds raised from any investor who was contacted or introduced by Maxim in connection with our prior offerings for any other financing of equity or equity-linked capital-raising activity during the 9-month period following the completion of a prior offering.

Maxim and certain of its 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, financing, and brokerage activities. The sales agent and certain of its affiliates may, in the future, perform various commercial and investment banking and financial advisory services for us and our affiliates, for which they would receive customary fees and expenses.

In the ordinary course of their various business activities, Maxim and certain of its 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 the accounts of their customers, and such investment and securities activities may involve securities and/or instruments issued by us and our affiliates. The sales agent and certain of its respective affiliates may also communicate independent investment recommendations, market color, or trading ideas and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Nevada law provides that a Nevada corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation (i.e., a “non-derivative proceeding”), by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with the action, suit or proceeding if he or she:

● Is not liable under Section 78.138 of the Nevada Revised Statutes for breach of his or her fiduciary duties to the corporation; or

● Acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

In addition, a Nevada corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor (i.e., a “derivative proceeding”), by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses, including amounts paid in settlement and attorneys’ fees actually and reasonably incurred by him or her in connection with the defense or settlement of the action or suit if he:

● Is not liable under Section 78.138 of the Nevada Revised Statute for breach of his or her fiduciary duties to the corporation; or

● Acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation.

II-1

Under Nevada law, indemnification may not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any non-derivative proceeding or any derivative proceeding, or in defense of any claim, issue or matter therein, the corporation is obligated to indemnify him or her against expenses, including attorneys’ fees, actually and reasonably incurred in connection with the defense.

Further, Nevada law permits a Nevada corporation to purchase and maintain insurance or to make other financial arrangements on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise for any liability asserted against him or her and liability and expenses incurred by him or her in his or her capacity as a director, officer, employee or agent, or arising out of his or her status as such, whether or not the corporation has the authority to indemnify him or her against such liability and expenses.

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

ITEM 16. EXHIBITS

A list of exhibits included as part of this registration statement is set forth in the Exhibit Index and is incorporated herein by reference.

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:

(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 Filing Fee Tables” 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;

II-2

provided, however, that subparagraphs (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 SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, 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; or

(5) That, for the purpose of determining liability of the Registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

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

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

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

(iv) Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

(b) The undersigned Registrant hereby undertakes that, for the purpose 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 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 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.
