Outlook and Guidance

Non-GAAP EPS is estimated in the range of $1.15 to $1.25 for 2016, excluding the impact of potential acquisitions.  InfraREIT is introducing Non-GAAP EPS as a supplemental measure of the Company’s operating performance to enable investors to compare InfraREIT with traditional regulated utility companies.  InfraREIT anticipates CAD per share for 2016 in the range of $1.15 to $1.25, excluding the impact of potential acquisitions.  

The Company estimates footprint capital expenditures in its current service territory in the following ranges over the next three years: $220 million to $240 million for 2016; $250 million to $280 million for 2017; and $170 million to $220 million for 2018.  The Company’s consolidated debt profile continues to target debt as a percentage of total capitalization at or below 60 percent and AFFO-to-debt of at least 12 percent.

The Company anticipates that footprint capital expenditures will enable a projected CAGR range in dividends per share of 8 percent to 10 percent from 2015 through 2018, with a targeted payout ratio of 80 percent to 90 percent. Additionally, the potential acquisition of both the Golden Spread Project and Cross Valley Project could add 1 percent to 2 percent growth to the Company’s projections for dividends per share CAGR from 2015 through 2018.

Recently filed Shelf Registration Statements are Unrelated to Company Financing Plans

On February 18, 2016, and March 3, 2016, the Company filed shelf registration statements on Form S-3 with the U.S. Securities and Exchange Commission (SEC).  However, these registration statements have no effect on, and do not relate to, the Company’s financing plans for its business.  The March 3^rd registration statement covers the potential resale from time-to-time of up to 22,192,899 shares of its common stock owned by certain of the Company’s founding investors. InfraREIT will not receive any cash proceeds from sales of the Company common stock pursuant to the registration statements.  These registration statements were filed in order to

2

comply with the Company’s obligations under the registration rights agreement entered into in connection with the Company’s IPO.  This agreement was subsequently amended on March 1, 2016 to, among other things, postpone the Company’s obligation to register for resale a portion of the shares owned by Hunt until Hunt’s lock-up obligations with respect to those securities expire in 2018 and 2020.  These registration statements have been filed with the SEC but have not yet become effective, and the securities registered thereunder may not be sold nor may offers to buy be accepted prior to the time the applicable registration statement becomes effective.

ROFO Project Updates

In November 2015, the Conflicts Committee of InfraREIT’s board of directors received an offer for the purchase of the Golden Spread Project.  The Conflicts Committee also received an offer for the purchase of the Cross Valley Project in February 2016.  Negotiations are in progress regarding the purchase of both projects.

Generally, InfraREIT’s monthly “ROFO Project Updates” will be provided after the closing of trading on the New York Stock Exchange on or about the 15th day of each month.  These ROFO Project Updates can be found on the Company’s Web site (www.InfraREITInc.com) under the “Hunt Transmission-Our Developer” and “Investor Relations” sections.  InfraREIT has also provided a ROFO Project Update in its “2015 Full Year Results & Supplemental Information” presentation posted on the Company’s Web site as of today.  The next ROFO Project Update will be issued on April 15, 2016.

Explanation and Reconciliation of FFO and AFFO

FFO and AFFO

The National Association of Real Estate Investment Trusts (NAREIT) defines FFO as net income (computed in accordance with GAAP), excluding gains and losses from sales of property (net) and impairments of depreciated real estate, plus real estate depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures.
