TRANSFERABLE UNIT SUBSCRIPTION RIGHTS

CERTIFICATE

PLEASE CONSULT THE INFORMATION AGENT, SUBSCRIPTION AGENT, ESCROW AGENT, YOUR BANK OR BROKER FOR ANY QUESTIONS

The following instructions relate to the rights offering being conducted by AMPLITECH GROUP, INC., a Nevada corporation, to holders of our common stock, and certain eligible warrantholders (pursuant to contractual rights), as described in the prospectus supplement dated October 30, 2025. Holders of our common stock and certain eligible warrantholders (pursuant to contractual rights), as of 5:00 p.m., Eastern time, on November 10, 2025 (the “Record Date”) are receiving, at no charge, (i) two transferable subscription rights (the “Unit Subscription Rights”), each entitling such holders to purchase one unit (“Unit”) for each basic subscription right at a price equal to $4.00 (the “Unit Subscription Price”), subject to potential pro rata adjustment due to the maximum Unit Subscription Rights limitation as set forth in the Prospectus; and (ii) an oversubscription privilege, which will be exercisable only if holder exercises his or her basic subscription right in full and will entitle holder to purchase additional Units for which other rights holders do not subscribe, subject to certain pro rata allocations and ownership limitations. Each Unit will consist of one share of common stock, par value $0.001 per share (“Common Stock”), one series A right (“Series A Right”) and one series B right (“Series B Right”, together with the Series A Right, collectively, the “Series Rights”), with each Series Right entitling the holder to purchase one share of our Common Stock. The offering of the Unit Subscription Rights and the Series Rights is referred to as the “offering.”

The Common Stock, Series A Right and Series B Right comprising the Units will separate upon the closing of the Unit Subscription Rights offering and will be issued separately but may only be purchased as a Unit. The Units will not be issued or traded as a separate security.

The Series Rights are exercisable commencing on their date of issuance at an exercise price equal to (i) in the case of the Series A Right, $5.00 and (ii) in the case of the Series B Right, $6.00.

The Unit Subscription Rights will be evidenced by transferable Unit Subscription Rights certificates (the “Transferable Unit Subscription Rights Certificate”). The number of basic subscription rights to which you are entitled is printed on the face of your Transferable Unit Subscription Rights Certificate.

Oversubscription Privilege

If a holder purchases all of the Units available to it pursuant to its basic subscription rights, it may also exercise an oversubscription privilege to purchase additional Units to the extent other rights holders do not exercise their basic subscription rights in full. Oversubscription privilege will be allocated pro rata among rights holders who oversubscribe, based on the number of oversubscription Units for which the rights holders have over-subscribed. If you exercise fewer than all of your basic subscription rights, however, you will not be entitled to purchase any additional Units pursuant to the oversubscription privilege. There will be no oversubscription privilege for the Series Rights.

If you wish to exercise your oversubscription privilege, you should deliver a completed Transferable Unit Subscription Rights Certificate indicating the number of additional Units that you would like to purchase in this rights offering to VStock Transfer, LLC (“Subscription Agent”) and the required payment to Citizens Bank, N.A. (“Escrow Agent”) by December 10, 2025, the expiration date of the subscription offering or, if your shares of Common Stock are held in an account with a broker-dealer, trust company, bank or other nominee that qualifies as an Eligible Guarantor Institution, deliver the required Nominee Holder Certification to the Subscription Agent and the required payment to the Escrow Agent by the expiration date of the Unit Subscription Rights offering. When you send in your Transferable Unit Subscription Rights Certificate to Subscription Agent, you must also send the aggregate Unit Subscription Price for the number of additional Units that you have requested to purchase to the Escrow Agent.

If the number of basic subscription rights exercised exceed the number of Units available, we will allocate the Units pro-rata among rights holders who subscribed based on the number of basic subscription rights for which the rights holders subscribed. If the number of Units remaining after the exercise of Unit Subscription Rights is not sufficient to satisfy all requests for Units pursuant to oversubscription privilege, we will allocate the remaining available Units pro rata among rights holders who oversubscribed based on the number of oversubscription Units for which the rights holders have oversubscribed. The Escrow Agent will promptly return any excess payments in the form in which made. To the extent your aggregate subscription payment for the actual number of Units available to you pursuant to the oversubscription privilege is less than the amount actually paid in connection with the exercise of the oversubscription privilege, you will be allocated only the number of unsubscribed Units available to you, and any excess subscription payment will be promptly returned to you, without interest or penalty, after the expiration of the Unit Subscription Rights offering.

In connection with the exercise of the oversubscription privilege, banks, brokers and other nominee holders of the basic subscription rights who act on behalf of beneficial owners will be required to certify to us and to the Subscription Agent as to the aggregate number of basic subscription rights exercised, and the number of Units requested through the oversubscription privilege, by each beneficial owner on whose behalf the nominee holder is acting.

Unit Subscription Rights may only be exercised in aggregate for whole numbers of Units. Only whole numbers of shares of Common Stock and Series Rights exercisable for whole numbers of shares of Common Stock will be issuable to you in this offering; any right to a fractional share to which you would otherwise be entitled will be terminated, without consideration to you. You are not required to exercise any or all of your basic subscription rights. If you do not exercise your Unit Subscription Rights, you will lose any value represented by your Unit Subscription Rights, and if you do not exercise your Unit Subscription Rights in full, your percentage ownership interest and related rights in our company will be diluted. Your percentage ownership of our voting stock may also decrease if you do not exercise your Unit Subscription Rights in full.

Expiration Time – Unit Subscription Rights

THE UNIT SUBSCRIPTION RIGHTS WILL EXPIRE AND WILL HAVE NO VALUE AT 5:00 P.M., EASTERN TIME, DECEMBER 10, 2025, SUBJECT TO EXTENSION OR EARLIER TERMINATION (THE “UNIT SUBSCRIPTION RIGHTS EXPIRATION DATE”). YOUR TRANSFERABLE UNIT SUBSCRIPTION RIGHTS CERTIFICATE MUST BE RECEIVED BY THE SUBSCRIPTION AGENT ON OR BEFORE 5:00 P.M., EASTERN TIME AND SUBSCRIPTION PAYMENT FOR EACH UNIT SUBSCRIPTION RIGHT THAT IS EXERCISED PURSUANT TO THE UNIT SUBSCRIPTION RIGHTS MUST BE RECEIVED BY THE ESCROW AGENT ON OR BEFORE 5:00 P.M., EASTERN TIME, ON THE UNIT SUBSCRIPTION RIGHTS EXPIRATION DATE. ONCE YOU HAVE EXERCISED YOUR UNIT SUBSCRIPTION RIGHTS, SUCH EXERCISE MAY NOT BE REVOKED OR CHANGED, EVEN IF YOU LATER LEARN INFORMATION THAT YOU CONSIDER TO BE UNFAVORABLE TO THE EXERCISE OF YOUR UNIT SUBSCRIPTION RIGHTS. UNIT SUBSCRIPTION RIGHTS NOT EXERCISED PRIOR TO 5:00 P.M., EASTERN TIME, ON THE UNIT SUBSCRIPTION RIGHTS EXPIRATION DATE WILL EXPIRE WITHOUT VALUE.

If you do not exercise your Unit Subscription Rights prior to that time, your Unit Subscription Rights will expire and will no longer be exercisable. We will not be required to sell Units to you if the Subscription Agent receives your Transferable Unit Subscription Rights Certificate after 5:00 p.m., Eastern time, on the Unit Subscription Rights Expiration Date or if the Escrow Agent receives your subscription payment after 5:00 p.m., Eastern time, on the Unit Subscription Rights Expiration Date regardless of when the Transferable Unit Subscription Rights Certificate and subscription payment were sent. If you send your Unit Transferable Subscription Rights Certificate, we recommend that you send them by registered mail, properly insured, with return receipt requested, and that a sufficient number of days be allowed to ensure delivery to the subscription agent and clearance of payment prior to the expiration of the subscription period or the date guaranteed payments are due under a notice of guaranteed delivery (as applicable).

The maximum number of Units available for issuance in this offering is 8,000,000. If at any time the issuance of Units pursuant to the exercise of the Unit Subscription Rights exceeds such share limitation, no additional Units will be issued, the Unit Subscription Rights offering will be terminated and any outstanding Unit Subscription Rights will immediately expire and the amount subscribed for by each holder will be proportionally reduced. In addition, if you own a small number of shares of Common Stock, your exercise of your Unit Subscription Rights may not result in the issuance of any Units. Although we intend to honor all properly exercised Unit Subscription Rights, there are circumstances under which a stockholder may not receive any shares upon exercising such rights. If the total number of Units requested in connection with the exercise of basic Unit Subscription Rights exceeds the maximum number of Units that may be issued under this Prospectus Supplement or the Registration Statement, allocations may be reduced on a pro rata basis, which could result in certain stockholders receiving none of the shares requested. In any such case, any payments made in connection with your subscription will be returned without interest, and you may not receive any Units even though you exercised your rights.
