SCHEDULE 13D

Explanatory Note

This Amendment No. 10 (this “ Amendment ”) amends and supplements the Schedule 13D (the “ Schedule 13D ”) jointly filed by Hunt Consolidated, Inc., a Delaware corporation (together with its subsidiaries, “ Hunt Consolidated ”), and Hunter L. Hunt, a citizen of the United States and (prior to the date hereof) a member of the board of directors (the “ Board ”) of InfraREIT, Inc., a Maryland corporation (“ InfraREIT Inc. ” and, together with its subsidiaries, the “ Company ”). Mr. Hunt is Co-Chairman, Co-CEO and Co-President of Hunt Consolidated and controls Hunt Consolidated through one or more intermediaries. Hunt Consolidated and Mr. Hunt are collectively referred to as the “ Reporting Persons .” This Amendment No. 10 relates to the common stock, par value $0.01 per share, of InfraREIT Inc. (“ Common Stock ”), including common units (“ common units ” and, together with the Common Stock, “ Securities ”) representing limited partnership interests in InfraREIT Partners, LP, a Delaware limited partnership (the “ Operating Partnership ”).

The Reporting Persons are filing this Amendment No. 10 to reflect certain updates described in Item 4 below regarding the consummation of the transactions contemplated by the InfraREIT Merger Agreement and the Asset Exchange Agreement (each as defined below). As a result of such transactions, the Reporting Persons’ beneficial ownership of the Securities has dropped below the 5% Schedule 13D reporting threshold. Therefore, this Amendment constitutes the final amendment to the Reporting Persons’ Schedule 13D and an exit filing for the Reporting Persons terminating the Reporting Persons’ obligation to further amend the Schedule 13D.

Item 2 is hereby supplemented and amended as follows:

(d) and (e). During the last five years, neither of the Reporting Persons nor, to the knowledge of the Reporting Persons, any person named on Appendix A  attached hereto has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which he was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or a finding of any violation with respect to such laws.

Item 4 is hereby supplemented and amended by replacing the final four paragraphs thereto with following:

On May 16, 2019, the transactions contemplated by the InfraREIT Merger Agreement, the Asset Exchange Agreement and the other agreements described above were consummated. The consequences of such transactions included the following:

In connection with seeking regulatory approvals necessary to consummate the transactions, Oncor and SU (i) waived the requirement to enter into the Future Development Agreement at the closing of the transactions and (ii) agreed to enter into an agreement addressing only certain operation services in lieu of the Operation and Maintenance Agreement at the closing of the transactions.

As a result of the transactions described above, the Reporting Persons no longer beneficially own any Securities.

Item 5 is hereby amended and restated in its entirety with the following:

(a), (b) As a result of the transactions described in Item 4, as of May 16, 2019, the Reporting Persons no longer beneficially own any Securities. As such, the Reporting Persons no longer have any voting or dispositive power over any shares of Securities.

(c) Except for the transactions described in Item 4, there were no transactions in the Securities effected by the Reporting Persons during the past 60 days.

(d) Not applicable.

(e) As a result of the transactions described in Item 4, as of May 16, 2019, the Reporting Persons ceased to be the beneficial owner of more than five percent of the Securities.
