Item 3.03 below is incorporated herein by reference in its entirety.

On April 8, 2020, the Board of Directors (the “Board”) of Neuronetics, Inc. (“Neuronetics”), a Delaware corporation, declared a dividend of one preferred share purchase right (each, a “Right”) for each outstanding share of Common Stock, par value $0.01 per share, of Neuronetics (“Neuronetics Common Stock”), and adopted a rights plan, as set forth in the Rights Agreement, dated as of April 8, 2020 (the “Rights Agreement”), by and between Neuronetics and American Stock Transfer & Trust Company, LLC, as rights agent. The dividend is payable to Neuronetics stockholders of record as of the close of business on April 20, 2020. The Rights will expire April 8, 2021.

The Board has adopted the Rights Agreement following careful consideration, among other factors, of the COVID-19 pandemic’s disruptive impact on market stability and its unprecedented effect on equity market valuations, including the recent dislocation of the Company’s stock price. The Rights Agreement is designed to assure that all of the Company’s stockholders receive fair and equal treatment in the event of any proposed takeover of the Company and to guard against opportunistic tactics to exert control over the Company. The Rights Agreement is intended to encourage anyone seeking to acquire the Company to negotiate with the Board prior to attempting a takeover. In general terms, the Rights Agreement deters abusive takeover tactics by significantly diluting any person or group that acquires 10% (15% in the case of a passive institutional investor) or more of the outstanding shares of Neuronetics Common Stock without the approval of the Board. The Rights Agreement should not interfere with any merger or other business combination approved by the Board.

A summary of the terms of the Rights Agreement and the Rights follows:

The Rights. The Rights will initially trade with, and will be inseparable from, the shares of Neuronetics Common Stock. New Rights will accompany any new shares of Neuronetics Common Stock issued after April 20, 2020 until the expiration, exchange or redemption of the Rights.

Exercisability. The Rights will not be exercisable until the earlier of (a) 10 days after the public announcement or disclosure that a person or group has become an “Acquiring Person” (as defined in the Rights Agreement) by obtaining beneficial ownership of 10% (15% in the case of a passive institutional investor) or more of the outstanding shares of Neuronetics Common Stock (the “Shares Acquisition Date”)  or, in the event that the Board determines on or before such 10th day to effect an exchange (as described below) and determines that a later date is advisable, such later date that is not more than 20 days after the Shares Acquisition Date or (b) 10 business days (or such later date as may be determined by action of the Board prior the time that any person or group has become an “Acquiring Person” (as defined in the Rights Agreement)) after the commencement by any person or group of, or the first public announcement that a person or group intends to commence a tender or exchange offer for Neuronetics Common Stock, the consummation of which would result in ownership by such person or group becoming an “Acquiring Person” (as defined in the Rights Agreement) by obtaining beneficial ownership of 10% (15% in the case of a passive institutional investor) or more of the outstanding shares of Neuronetics Common Stock. Prior to exercise, the Right does not give its holder any dividend, voting or liquidation rights.

The date when the Rights become exercisable is referred to herein as the “Distribution Date.” Until that date, Neuronetics Common Stock certificates or, in the case of uncertificated shares, notations in the book-entry account system, will evidence the Rights, and any transfer of shares of Neuronetics Common Stock will also constitute a transfer of such Rights. After the Distribution Date, the Rights will separate from the shares of Neuronetics Common Stock and be evidenced by book-entry credits or by Rights certificates that Neuronetics will mail to all applicable holders of Neuronetics Common Stock. Any Rights held by an Acquiring Person are null and void and may not be exercised.

Exercise Price. Each Right will allow its holder to purchase from Neuronetics one one-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share (“Preferred Share”), for $12.00 (the “Exercise Price”), once the Rights become exercisable. This portion of a Preferred Share will give the stockholder approximately the same dividend, voting and liquidation rights as would one share of Neuronetics Common Stock.

Beneficial Ownership. Certain synthetic interests in securities created by derivative positions — whether or not such interests are considered to be ownership of underlying shares of Neuronetics Common Stock or are reportable for purposes of Regulation 13D of the Securities Exchange Act of 1934, as amended — are treated as beneficial ownership of the number of shares of Neuronetics Common Stock equivalent to the economic exposure created by the derivative position, to the extent actual shares of Neuronetics Common Stock are directly or indirectly held by counterparties to the derivatives contracts. In addition, shares held by Affiliates and Associates of an Acquiring Person, and shares which are the subject of, or the reference securities for, or that underlie any Derivative Position of an Acquiring Person or such

Acquiring Person’s Affiliates or Associates, will be deemed to be beneficially owned by the Acquiring Person (in each case as such capitalized terms are defined in the Rights Agreement).

Consequences of a Person or Group Becoming an Acquiring Person.

Each one one-thousandth of a Preferred Share, if issued (among other matters):

The value of a one one-thousandth interest in a Preferred Share approximates the value of one share of Neuronetics Common Stock.

Expiration. The Rights will expire on April 8, 2021.

Redemption. The Board may redeem the Rights for $0.01 per Right at any time before any person or group becomes an Acquiring Person. If the Board redeems any Rights, it must redeem all of the Rights. Once the Rights are redeemed, the only right of the holders of Rights will be to receive the redemption price of $0.01 per Right. The redemption price will be adjusted if Neuronetics effects a stock split or stock dividend of Neuronetics Common Stock.

Anti-Dilution Provisions. The Board may adjust the Exercise Price, the number of Preferred Shares issuable and the number of outstanding Rights to prevent dilution that may occur from a stock dividend, a stock split or other reclassification of the Preferred Shares or Neuronetics Common Stock. No adjustments to the Exercise Price of less than 1% will be made.

Amendments. The terms of the Rights Agreement may be amended by the Board without the consent of the holders of the Rights. After a person or group becomes an Acquiring Person, the Board may not amend the Rights Agreement in a way that adversely affects holders of the Rights.
