Completion of 1-for-10 Reverse Stock Split

On October 5, 2026, Granite Point Mortgage Trust Inc. (the “Company”)

completed the previously announced reverse stock split of shares of the Company’s common stock (the “Common Stock”)

at a ratio of one share for every ten shares outstanding (the “Reverse Stock Split”). The Reverse Stock Split took effect

at 5:00 p.m. Eastern Time on October 5, 2026 (the “Effective Time”) and automatically converted every ten shares

of Common Stock outstanding at that time into one share of Common Stock.

The Reverse Stock Split affected all holders of Common Stock uniformly

and did not affect any common stockholder’s percentage ownership interest in the Company, except for de minimis changes resulting

from the elimination of fractional shares, as described below under “Charter Amendments.” Holders of Common Stock were not

required to take any action related to the Reverse Stock Split. Their accounts were automatically adjusted to reflect the number of shares

owned.

As a net result of the Reverse Stock Split, the number of shares of

Common Stock issued and outstanding decreased from 48,198,166 shares to approximately 4,819,100 shares as of the Effective Time.

At the Effective Time, the aggregate number of shares of Common Stock

available for awards under the Company’s Amended and Restated 2022 Omnibus Incentive Plan (the “Incentive Plan”) and

the terms of outstanding awards that had been issued under the Incentive Plan were ratably adjusted to reflect the Reverse Stock Split.

The Reverse Stock Split will not affect payment of the previously announced

Common Stock dividend. The dividend will remain payable on October 15, 2026, to stockholders of record at the close of business on

October 1, 2026, based on their pre-split holdings of Common Stock, at the previously announced rate of $0.01 per pre-split share.

The Reverse Stock Split applies only to the Common Stock and did not

affect the outstanding shares or terms of the Company’s 7.00% Series A Fixed-to-Floating Rate Cumulative Redeemable Preferred

Stock.

Charter Amendments

In connection with and to implement the Reverse Stock Split, on October 2,

2026, the Company filed two Articles of Amendment to its charter with the State Department of Assessments and Taxation of Maryland that

provided for:

i. a 1-for-10 Reverse Stock Split of the Common Stock, effective at 5:00 p.m. Eastern Time on October 5, 2026, payment of fractional

shares in cash, and a corresponding and statutorily required increase in the par value per share of Common Stock from $0.01 per share

to $0.10 per share (the “First Amendment”); and

ii. the restoration of the par value per share of the Common Stock to $0.01 per share, effective immediately following the effectiveness

of the First Amendment (the “Second Amendment”).

Trading of the Common Stock on the New York Stock Exchange commenced

on a Reverse Stock Split-adjusted basis on October 6, 2026, under the existing trading symbol “GPMT.” The new CUSIP number

for the Common Stock following the Reverse Stock Split is 38741L 404.

Pursuant to the First Amendment, any fractional share of Common Stock

that would otherwise have resulted from the Reverse Stock Split will be settled by cash payment, calculated on the basis of the closing

price of the Common Stock on October 5, 2026.

The foregoing descriptions of the First Amendment and the Second Amendment

do not purport to be complete and are qualified in their entirety by reference to each amendment, copies of which are filed as Exhibit 3.1

and Exhibit 3.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.

Exhibit 3.1

GRANITE POINT MORTGAGE TRUST INC.

ARTICLES OF AMENDMENT

Granite Point Mortgage Trust

Inc., a Maryland corporation (the “Corporation”), hereby certifies to the State Department of Assessments and Taxation of

Maryland that:

FIRST: The Corporation

desires to, and does hereby, amend its charter as currently in effect (the “Charter”), pursuant to Section 2-309(e) of

the Maryland General Corporation Law (the “MGCL”), to effect a reverse stock split of the issued and outstanding shares of

the common stock, par value $0.01 per share (the “Common Stock”), of the Corporation such that:

(i) every ten (10) shares

of Common Stock of the Corporation, par value $0.01 per share, that are issued and outstanding immediately prior to the Effective Time

(as defined herein) shall, at the Effective Time, be combined and changed into one (1) issued and outstanding share of Common Stock

of the Corporation, par value $0.10 per share;

(ii) no fractional shares

of Common Stock of the Corporation resulting from such combination and change will be or remain issued and outstanding following the

Effective Time, and each stockholder otherwise entitled to a fractional share will be entitled to receive, in lieu thereof, cash in an

amount equal to the product obtained by multiplying (x) the fraction of a share by (y) the last reported price per share at

which shares of Common Stock of the Corporation sold on the New York Stock Exchange at the close of market on the date on which the Effective

Time occurs;

(iii) shares of Common

Stock of the Corporation representing the difference between the number of shares of Common Stock of the Corporation issued and outstanding

immediately prior to the Effective Time and the number of shares Common Stock of the Corporation issued and outstanding immediately following

the Effective Time, shall be and become authorized and unissued shares of Common Stock of the Corporation having a par value of $0.10

per share; and

(iv) immediately upon

the Effective Time, each certificate representing shares of Common Stock of the Corporation will continue to be valid but will be deemed

for all corporate purposes after the Effective Time, until such certificate is surrendered in accordance with procedures established

by the Corporation, to evidence ownership of the appropriately reduced number of shares of Common Stock of the Corporation, and upon

proper surrender of such certificates, new certificates representing the appropriate number of shares (excluding fractional shares) of

Common Stock of the Corporation after the combination and change described above will be issued by the Corporation.

SECOND: The Corporation

desires to, and does hereby, further amend its Charter pursuant to Section 2-605 of the MGCL to change the par value of each authorized

share of Common Stock of the Corporation from $0.01 per share to $0.10 per share, effective as of the Effective Time.

THIRD: As of immediately

before the reverse stock split described in Article FIRST and the change in the par value per share of the authorized shares of

Common Stock of the Corporation described in Article SECOND, the total number of shares of stock of all classes that the Corporation

had authority to issue was 500,000,000 shares of stock, consisting of 450,000,000 shares of Common Stock, par value $0.01 per share,

and 50,000,000 shares of preferred stock, par value $0.01 per share. The aggregate par value of all such authorized shares of stock having

par value was $5,000,000.

FOURTH: As of the

Effective Time, after giving effect to the reverse stock split described in Article FIRST and the change in the par value per share

of the authorized shares of Common Stock of the Corporation described in Article SECOND, the total number of shares of stock of

all classes that the Corporation has authority to issue will be 500,000,000 shares of stock, consisting of 450,000,000 shares of Common

Stock, par value $0.10 per share, and 50,000,000 shares of preferred stock, par value $0.01 per share. By virtue of the change in the

par value per share of the shares of Common Stock of the Corporation from $0.01 per share to $0.10 per share, the aggregate par value

of the total number of shares of stock of all classes that the Corporation has authority to issue will be $45,500,000.

FIFTH: The foregoing

amendments to the Charter as set forth in these Articles of Amendment are for the purpose of effecting a reverse stock split that results

in a combination of issued and outstanding shares of Common Stock of the Corporation and a change in the par value of the authorized

shares of Common Stock of the Corporation, and such amendments are limited to changes expressly authorized by Sections 2-309(e) and

2-605 of the MGCL, respectively, to be made without action by the stockholders of the Corporation and were approved by a majority of

the entire board of directors of the Corporation without action by the stockholders of the Corporation.

SIXTH: The foregoing

amendments to the Charter as set forth in these Articles of Amendment do not increase the authorized stock of the Corporation.

SEVENTH: The information

NEW YORK, October 6,

common stock (the “Reverse Stock Split”). The Reverse Stock Split, which was effective at 5:00 p.m. Eastern Time on

Reverse Stock Split, including the applicability and effect of any U.S. federal, state, local or foreign tax laws.
