DALLAS, TEXAS, Aug. 1, 2018—InfraREIT, Inc. (NYSE: HIFR) (“InfraREIT” or the “Company”) today reported financial results for the second quarter and first half of 2018 and provided the Company’s financial outlook.

For the second quarter of 2018, InfraREIT reported the following highlights:

Guidance:

“We remain focused on executing our business strategy,” said David A. Campbell, Chief Executive Officer of InfraREIT.  “We are committed to investing in infrastructure needed to support the ERCOT transmission grid and the vibrant Texas economy.  At the same time, we continue to pursue possible De-REIT alternatives,” added Campbell.

Second Quarter 2018 Results

Lease revenue, consisting of only base rent, increased 18 percent to $47.8 million for the three months ended June 30, 2018, compared to $40.4 million for the same period in 2017.  The increase in lease revenue was driven by the change in the allocation of the total rent components between base and percentage rent and additional assets under lease.  There was no percentage rent recognized during the second quarter of 2018 or 2017.

Net income was $23.9 million in the second quarter of 2018, compared to net income of $10.1 million in the second quarter of 2017.  Net income attributable to InfraREIT, Inc. common stockholders was $0.39 per share during the second quarter of 2018 compared to $0.17 per share during the same period in 2017.  The $13.8 million increase in net income was a result of a $7.4 million increase in lease revenue, $5.6 million benefit from the Texas franchise tax settlement, $1.0 million decrease in depreciation expense and $0.4 million increase in other income, net partially offset by a $1.0 million increase in interest expense, net.  Additionally, the decrease in general and administrative expense contributed $0.3 million to net income.  During the second quarter of 2018, the Company incurred a $1.2 million professional services fee associated with the settlement of its Texas franchise taxes and a $0.4 million net increase in expenses primarily due to InfraREIT’s continued review of its De-REIT alternatives and decreased management fees.  During the second quarter of 2017, InfraREIT incurred $1.9 million of professional services fees related to the asset exchange transaction completed during the fourth quarter of 2017 (“Asset Exchange Transaction”).

Non-GAAP EPS was $0.29 per share for the second quarter of 2018 compared to $0.20 per share for the second quarter of 2017, representing an increase of 45 percent.  The drivers of growth in Non-GAAP EPS were due to an increase in lease revenue of $7.4 million, an increase of $0.4 million in other income, net and a $1.0 million decrease in depreciation expense offset by a $2.4 million base rent adjustment reduction, an increase of $1.0 million in interest expense, net and a $0.4 million net increase in general and administrative expense.  FFO was $35.9 million for the second quarter of 2018, compared to $23.1 million for the same period in 2017, representing an increase of $12.8 million.  For the second quarter of 2018, AFFO was $29.1 million, compared to $25.4 million for the same period in 2017, representing an increase of 15 percent.

First Half of 2018 Results

Lease revenue, consisting of only base rent, increased 17 percent to $93.5 million for the six months ended June 30, 2018, compared to $80.0 million for the same period in 2017.  The increase in lease revenue was driven by the change in the allocation of the total rent components between base and percentage rent and additional assets under lease.  There was no percentage rent recognized during the first half of 2018 or 2017 as Sharyland Utilities, L.P.’s (“Sharyland”) year-to-date adjusted gross revenue did not exceed the annual specified breakpoints under the Company’s leases.  The Company expects to begin recognizing percentage rent during the third quarter of 2018.

Net income was $41.7 million in the first half of 2018, compared to net income of $21.1 million for the same period in 2017.  Net income attributable to InfraREIT, Inc. common stockholders was $0.69 per share for the six months ended June 30, 2018 compared to $0.35 per share during the same period in 2017.  The $20.6 million increase in net income is a result of a $13.5 million increase in lease revenue, $5.6 million benefit from the Texas franchise tax settlement, $2.1 million decrease in depreciation expense and $1.1 million increase in other income, net partially offset by a $1.9 million increase in interest expense, net.  Additionally, the decrease in general and administrative expense contributed $0.1 million to net income.  During 2018, the Company incurred a $1.2 million professional services fee associated with the settlement of the Company’s Texas franchise taxes and a $1.0 million net increase in expenses primarily due to InfraREIT’s continued review of its De-REIT alternatives, evaluation of the impacts of the Tax Cuts and Jobs Act, Asset Exchange Transaction expenses and decreased management fees.  During 2017, the Company incurred $0.4 million of regulatory expenses and $1.9 million of professional services fees related to the Asset Exchange Transaction.

Non-GAAP EPS was $0.58 per share for the first half of 2018 compared to $0.40 per share for the first half of 2017, representing an increase of 45 percent.  The drivers of growth in Non-GAAP EPS were due to an increase in lease revenue of $13.5 million, an increase of $1.1 million in other income, net and a $2.1 million decrease in depreciation expense offset by a $3.4 million base rent adjustment reduction, an increase of $1.9 million in interest expense, net and a $0.6 million net increase in general and administrative expense.  FFO was $65.3 million for the first half of 2018, compared to $46.8 million for the same period in 2017, representing an increase of $18.5 million.  For the first six months of 2018, AFFO was $57.7 million, compared to $50.0 million for the same period in 2017, representing an increase of 15 percent.

Liquidity and Capital Resources

As of June 30, 2018, the Company had $2.1 million of unrestricted cash and cash equivalents and $225.5 million of unused capacity under its revolving credit facilities.

Outlook and Guidance

EPS is projected in the range of $1.36 to $1.46 for 2018, updated to reflect the impact of the Texas franchise tax settlement and related costs.  Non-GAAP EPS is estimated in the range of $1.22 to $1.32 for 2018.  The difference between Non-GAAP EPS and EPS is due to adjustments related to straight-line rent; expenses associated with the Asset Exchange Transaction; professional services fee related to the Texas franchise tax settlement; and the removal of the accrued taxes, penalties and interest related to the Texas franchise tax settlement.  InfraREIT expects to maintain the Company’s current quarterly cash dividend of $0.25 per share, or $1.00 per share annualized, through 2018.  These forecasted amounts assume that InfraREIT maintains its REIT status throughout 2018 and that the existing lease payments are made by Sharyland as scheduled during 2018.

The Company estimates footprint capital expenditures in the following ranges over the next three years: $50 million to $80 million for 2018; $10 million to $30 million for 2019; and $10 million to $50 million for 2020.  The footprint capital expenditures range for 2019 was updated to reflect the anticipated timing of the third synchronous condenser.

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 guidance provided above constitutes forward-looking statements, which are based on current economic conditions and estimates, and the Company does not include other potential impacts, such as changes in accounting or unusual items. Supplemental information relating to the Company’s financial outlook is posted in the Investor Relations section of the Company’s Web site at www.InfraREITInc.com.

Company Structure Review

As previously disclosed, InfraREIT’s Board of Directors completed its initial review of the Company’s REIT status and directed management to pursue an alternative structure that would involve, among other things, terminating InfraREIT’s REIT status and opting for a traditional C-corporation structure (a “De-REIT alternative”).  Any De-REIT alternative could involve one or more of the following: combining Sharyland with Sharyland Distribution & Transmission Services, L.L.C. (“SDTS”), terminating the leases between SDTS and Sharyland, terminating the Company’s operating partnership, and/or other negotiations with Hunt Consolidated, Inc. (“Hunt”), including terminating or renegotiating the Company’s management agreement and development agreement, and engaging in related negotiations.  As further disclosed, in tandem with our evaluation of a De-REIT alternative, the Conflicts

Committee continues to monitor Hunt’s Schedule 13D filings regarding their intentions with respect to InfraREIT, including those described below.  It is possible that any transaction that might be proposed as a result of the efforts described in Hunt’s Schedule 13D filings regarding InfraREIT could serve as the De-REIT alternative that InfraREIT ultimately chooses.

There is no specific timeline set for completing the evaluation of a De-REIT alternative, and the Company expects to continue operating as a REIT until the execution of a De-REIT alternative, if any.  Hunt has informed the Company that it agrees with the Board’s direction.

Hunt Consolidated, Inc.’s Schedule 13D

In January 2018, Hunt filed an amendment to its Schedule 13D with the U.S. Securities and Exchange Commission (“SEC”) stating its intent to focus on evaluating and developing a “going private” transaction with respect to InfraREIT.  On May 24, 2018, Hunt further amended its Schedule 13D (“13D Amendment”).  According to the 13D Amendment, Hunt did not believe that a “going private” transaction was likely to be viable, although Hunt may elect to consider and pursue such a transaction in the future.

As described in the 13D Amendment, during Hunt’s discussions with various parties about participating in a “going private” transaction, certain parties expressed interest in a possible direct acquisition of InfraREIT as an alternative to a “going private” transaction. Hunt further disclosed that it was engaged in discussions with potential third-party acquirers regarding certain transactions and arrangements that would be implemented in connection with an acquisition of InfraREIT by a third party (“Third-Party Acquisition”).  Hunt noted that these arrangements may include the possible termination of certain agreements between Hunt and its subsidiaries and affiliates, including Sharyland, and InfraREIT.

No assurances can be given that InfraREIT will agree to any transaction proposed as a result of the efforts described in Hunt’s 13D Amendment or that any De-REIT alternatives will be executed.  InfraREIT’s Board of Directors and the Conflicts Committee intend to explore various De-REIT alternatives and will carefully consider any proposal that may be submitted to the Company in conjunction with the efforts described in Hunt’s 13D Amendment.  InfraREIT’s Board of Directors and its Conflicts Committee are committed to advancing the interests of its stockholders.

InfraREIT does not plan to provide further updates on the status of any Third-Party Acquisition or other De-REIT alternative. If any agreement is reached, or if Hunt further updates its Schedule 13D, InfraREIT will provide additional information at that time.

Dividends and Distributions

On June 1, 2018, InfraREIT’s Board of Directors declared cash distributions and dividends of $0.25 per unit and share, respectively, to unitholders and stockholders of record on June 29, 2018, which were paid on July 19, 2018.

Conference Call and Webcast

As previously announced, management will host a teleconference call on August 1, 2018, at 10 a.m. U.S. Central Time (11 a.m. U.S. Eastern Time).  David A. Campbell, Chief Executive Officer, and Brant Meleski, Chief Financial Officer, will discuss InfraREIT’s results and financial outlook.

Non-GAAP Measures

This press release contains certain financial measures that are not recognized under generally accepted principles in the United States of America (“GAAP”). In particular, InfraREIT uses Non-GAAP EPS, FFO and AFFO as important supplemental measures of the Company’s operating performance.  InfraREIT is no longer including cash available for distribution (“CAD”); earnings before interest, taxes, depreciation and amortization (“EBITDA”); and Adjusted EBITDA.  The Company presents non-GAAP performance measures because management believes they help investors understand InfraREIT’s business, performance and ability to earn and distribute cash to its stockholders by providing perspectives not immediately apparent from net income. Reporting on these measures in InfraREIT’s public disclosures also ensures that this information is available to all of InfraREIT’s investors.  The non-GAAP measures presented in this press release are not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

InfraREIT offers these measures to assist users in assessing the Company’s operating performance under GAAP, but these measures are non-GAAP measures and should not be considered measures of liquidity, alternatives to net income or indicators of any other performance measures determined in accordance with GAAP, nor are they indicative of funds available to fund the Company’s cash needs, including capital expenditures, make payments on the Company’s indebtedness or make distributions.  In addition, InfraREIT’s method of calculating these measures may be different from methods used by other companies and, accordingly, may not be comparable to similar measures as calculated by other companies.  Investors should not rely on these measures as a substitute for any GAAP measure, including net income, cash flows from operating activities or revenues.  Reconciliations of these measures to their most directly comparable GAAP measures are included in the Schedules to this press release.

InfraREIT, Inc.

Explanation and Reconciliation of Non-GAAP EPS

Non-GAAP EPS

InfraREIT defines non-GAAP net income as net income (loss) adjusted in a manner the Company believes is appropriate to show its core operational performance, which includes (a) an adjustment for the difference between the amount of base rent payments that the Company receives with respect to the applicable period and the amount of straight-line base rent recognized under GAAP; (b) adding back the transaction costs related to the Asset Exchange Transaction; (c) adding back the professional services fee related to the franchise tax settlement with the state of Texas; and (d) removing the effect of the Texas franchise tax settlement.  The Company defines Non-GAAP EPS as non-GAAP net income (loss) divided by the weighted average shares outstanding calculated in the manner described in the footnotes below.

Schedule 2

InfraREIT, Inc.

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. Applying the NAREIT definition to the Company’s consolidated financial statements, which is the basis for the FFO presented in this press release and the reconciliations below, results in FFO representing net income (loss) before depreciation, impairment of assets and gain (loss) on sale of assets. FFO does not represent cash generated from operations as defined by GAAP and it is not indicative of cash available to fund all cash needs, including distributions.

AFFO is defined as FFO adjusted in a manner the Company believes is appropriate to show its core operational performance, including: (a) an adjustment for the difference between the amount of base rent payments that the Company receives with respect to the applicable period and the amount of straight-line base rent recognized under GAAP; (b) adding back the transaction costs related to the Asset Exchange Transaction; (c) adjusting for other income (expense), net; (d) adding back the professional services fee related to the franchise tax settlement with the state of Texas; and (e) removing the effect of the Texas franchise tax settlement.

The following table sets forth a reconciliation of net income to FFO and AFFO:

The Company provides yearly guidance for Non-GAAP EPS, which is one of the supplemental financial measures it uses in evaluating the Company’s operating performance.  The Company believes that Non-GAAP EPS helps the Company and investors better understand the Company’s business and performance by providing perspectives not immediately apparent from net income.
