SPECIAL MEETING OF GREENWAY TECHNOLOGIES SHAREHOLDERS, INC.
TO BE HELD ON APRIL 4, 2019

_______

To the Greenway Technologies, Inc. shareholders:

Pursuant to a Definitive Proxy Statement filed by the Greenway Technologies Shareholder Committee on February 8, 2019, you have previously been notified that the 2019 Special Meeting of the shareholders of Greenway Technologies, Inc., a Texas corporation (sometimes “Greenway Technologies”) will be held at 4:00 p.m., Central Time, on April 4, 2019, at the Holiday Inn located at 3005 Airport Freeway, Bedford, Texas 76021 (the “2019 Special Meeting”), for the following purposes:

1.

If the current president of Greenway Technologies refuses to act as the chairman of the 2019 Special Meeting, to elect David Deison as the chairman of the 2019 Special Meeting as described in the Proxy Statement (Proposal 1);

2.

To elect seven persons to the Greenway Technologies board of directors as described in the Proxy Statement (Proposal 2);

3.

To approve the reimbursement of the Greenway Technologies Shareholder Committee for all of its expenses in connection with the Notice and Proxy Statement as described in the Proxy Statement (Proposal 3);

4.

After the election of the persons described in Proposal 2, to ratify the appointment of Soles, Heyn & Company LLC as Greenway Technologies’ independent registered public accounting firm for the fiscal year ended December 31, 2018, as described in the Proxy Statement (Proposal 4); and

5.

To transact such other business as may properly come before the 2019 Special Meeting or any adjournment or postponement thereof.

On February 20, 2019, D. Patrick Six, a member of the Greenway Technologies Shareholder Committee, resigned as a member of the committee and also requested that his name be withdrawn as a candidate for election as a director or officer of Greenway Technologies and as one of the members of the committee to whom proxies may be granted as described in the Proxy Materials filed by the Greenway Technologies Shareholder Committee.  At the same time, Mr. Six resigned as a current member of the board of directors of Greenway Technologies.

As a result of Mr. Six’s resignation as a member of the board of directors of Greenway Technologies, the board of Greenway Technologies now consists of only six members and not seven as previously described in the Greenway Technologies Shareholder Committee Proxy Materials.  By his actions, Mr. Six will not be considered for selection as Vice President and Secretary of Greenway Technologies by the newly elected board of directors of Greenway Technologies.

Inasmuch as the board of directors of Greenway Technologies has been reduced from seven to six, as a result of the resignation of Mr. Six, and due to the resignation of Mr. Six as a member of the Greenway Technologies Shareholder Committee, the proposal to elect seven persons to the Greenway Technologies board of directors as described in the Greenway Technologies Shareholder Committee Proxy Statement (Proposal 2) has been changed from seven to six persons (excluding D. Patrick Six).  The enclosed paper GREEN proxy card reflects the change, as well as removing Mr. Six as one of the persons to whom proxies may be granted.

On February 22, 2019, the management of Greenway Technologies filed with Securities and Exchange Commission a preliminary proxy statement pursuant to Section 14(a) of the Securities Exchange Act of 1934, as amended, (the “PRE 14A”), whereby management gave notice of its intention to call an annual meeting of shareholders (the “Annual Meeting”) of Greenway Technologies.

Before proxies can be solicited pursuant to the PRE 14A filed by the management of Greenway Technologies, a DEF 14A must be filed by management.  At this time, we have no idea when the Annual Meeting will be held, but it is unlikely that it will be before April 4, 2019, the date of the 2019 Special Meeting called by the Greenway Technologies Shareholder Committee, due to the notice requirements contained in the rules of the Securities and Exchange Commission.

Due to the actions of D. Patrick Six, as above-specified, it is necessary to discuss the effect of Mr. Six’s actions on those shareholders who have already submitted proxies with respect to the election of directors as described in the Greenway Technologies Shareholder Committee Proxy Materials.  In addition, it is necessary to discuss the effect of the filing of the PRE 14A by the management of Greenway Technologies.

IT IS IMPORTANT FOR YOU TO READ THIS PROXY SUPPLEMENT AND VOTE ON THE ENCLOSED GREEN PROXY CARD.

The members of the Greenway Technologies Shareholder Committee unequivocally continue to support the proposals set forth in the Greenway Technologies Shareholder Committee Proxy Materials, as modified by this proxy supplement, and respectfully ask for your vote in accordance therewith.

THE PASSAGE OF THE PROPOSALS PUT FORWARD BY THE GREENWAY TECHNOLOGIES SHAREHOLDER COMMITTEE ARE NECESSARY FOR THE SURVIVAL OF GREENWAY TECHNOLOGIES BY THE INSTALATION OF PROPER MANAGEMENT IN ORDER TO IMPLEMENT THE GREENWAY TECHNOLOGIES GAS TO LIQUID TECHNOLOGY SO AS TO ENSURE LONG TERM GROWTH FOR GREENWAY TECHNOLOGIES AND TO INCREASE SHAREHOLDER VALUE.

We believe it is important to address some key questions you may have.

What About The Annual Meeting Called By Management?

As mentioned above, management of Greenway Technologies has filed the PRE 14A on February 22, 2019, purporting to call an Annual Meeting.  The PRE 14A is deficient in many respects, all of which will have to be resolved, before proxies may be solicited by management, pursuant to a DEF 14A, in connection with the proposed Annual Meeting.

Consequently, the putative calling of the Annual Meeting by management should have no effect on the 2019 Special Meeting, due to the likelihood that the Annual Meeting cannot be held before April 4, 2019, inasmuch as management is not expected to meet the time requirements to call for a meeting before April 4, 2019. If, at the 2019 Special Meeting on April 4, 2019, management of Greenway Technologies is replaced by the slate proposed by the Greenway Technologies Shareholder Committee, which should be before the Annual Meeting, the PRE 14A filed by management is expected to be withdrawn by the new management.

If I Voted Previously for D. Patrick Six, But Do Not Submit a New Proxy, Will My Vote for Mr. Six Still Count?
