Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Represents the portions of previous awards of restricted stock rights that vested effective as of March 7, 2018.
(10) Total represents phantom stock shares of PNM Resources, Inc. Common Stock acquired under the PNM Resources, Inc. Executive Savings Plan II as of February 28, 2018.
(2) Represents shares withheld by PNM Resources, Inc. to satisfy the tax withholding obligations arising in connection with the settlement of equity awards. The company utilizes a modified "share withholding" approach in connection with settling equity awards, in which it (i) withholds (in cash) an amount to satisfy tax withholding obligations and remits such amount to the relevant tax authorities, and (ii) directs a designated broker to purchase on the open market the number of shares of the company's common stock that can be acquired with the after-tax value of equity awards at the prevailing market price. Only these "net shares" are delivered to the recipient of the equity awards.
(3) Each restricted stock right represents a contingent right to receive one share of PNM Resources, Inc. common stock.
(4) The restricted stock units vest in three equal annual installments. Vested shares will be delivered to the reporting person on the applicable vesting dates (or, if the company is in a blackout period under its insider trading policy on any vesting date, at a later date after such blackout period ends).
(5) Based on the closing price on the date of the grant.
(6) The options vested in three equal annual installments from grant date and are fully vested.
(7) The options expire 10 years from grant date.
(8) The security converts to common stock on a one-for-one basis.
(9) The phantom stock shares were acquired under the PNM Resources, Inc. Executive Savings Plan, and will settle upon the Reporting Person's retirement or other termination of service.
