Ormat Technologies Reports 2017 Second Quarter Earnings

Total Revenues increased 12% and Net income attributable to the company's shareholders increased 44%

Company Reiterates Full-Year Guidance

RENO, Nev. August 3, 2017 - Ormat Technologies, Inc. (NYSE: ORA) today announced financial results for the second quarter ended June 30, 2017.

Financial Summary:

Second Quarter 2017 Highlights and Recent Developments:

__________________________________

^[1] Adjusted Net income attributable to the Company’s stockholders and diluted EPS excludes $5.5 million and $0.11 per diluted share, respectively, of one-time benefit related to tax restructuring as will be fully described in our quarterly report on Form 10Q that will be filled with the SEC on August 4, 2017.

“Continued growth in our electricity segment and a strong quarter for our products segment enabled us to deliver 12.2% top-line growth in the second quarter,” commented Isaac Angel, Chief Executive Officer. “Our focus on streamlining our entire value chain over the past three years enabled us to increase electricity segment gross margin to 41.5% and to grow our Adjusted EBITDA by 8.5%, demonstrating the strength of our business.”

“During the second quarter we signed the new portfolio PPA with SCPPA. This portfolio PPA will enable both the development of multiple new projects as well as the sustainable operation of several of our existing geothermal power plants. With the SCPPA portfolio PPA in place, Ormat is well positioned for consistent growth in the US. Another recent noteworthy development is that with the closing of ORIX’s acquisition of an approximately 22% ownership stake in Ormat, the Commercial Cooperation Agreement that Ormat and ORIX executed in connection with that acquisition became effective last week, and we expect that it will expand our business opportunities in Asia and other key geographies and may also improve our access to capital,” added Mr. Angel.

Guidance 

Mr. Angel added, “We reiterate our guidance and expect full-year 2017 total revenues between $680.0 million and $700.0 million with electricity segment revenues between $460.0 million and $470.0 million and product segment revenues between $220.0 million and $230.0 million. We expect 2017 Adjusted EBITDA between $340 million and $350 million for the full year. We expect annual Adjusted EBITDA attributable to non-controlling interest to be approximately $23.0 million.”

Second Quarter 2017 Financial Results

For the three months ended June 30, 2017, total revenues were $179.4 million, up from $159.9 million for the three months ended June 30, 2016, an increase of 12.2%. Electricity segment revenues increased 7.5% to $111.8 million in the three months ended June 30, 2017, up from $104.0 million for the three months ended June 30, 2016. Product segment revenues increased 21.0% to $67.6 million for the three months ended June 30, 2017, up from $55.9 million in the three months ended June 30, 2016.

__________________________________

² Backlog as of August 3, 2017 includes revenues for the period between July 1, 2017 and August 3, 2017.

General and administrative expenses for the three months ended June 30, 2017 were $12.2 million, or 6.8% of total revenues, compared to $8.8 million, or 5.5% of total revenues, for the three months ended June 30, 2016. The increase was mainly due to a $2.1 million non-cash charge for stock-based compensation expense associated with the acceleration of the vesting period of the stock options of the CEO and the CFO as part of ORIX’s acquisition of 22% of ownership stake in Ormat; and $0.9 million of costs associated with the ORIX transaction and Ormat’s M&A activities.

The company reported net income attributable to the company’s shareholders of $35.0 million, or $0.69 per diluted share, compared to net income attributable to the company’s shareholders of $24.3 million, or $0.49 per diluted share, for the same period last year. Adjusted net income attributable to the company’s shareholders was $29.5 million, or $0.58 per diluted share, which excludes $5.5 million and $0.11 per diluted share, respectively, of one-time benefit related to tax restructuring.

Adjusted EBITDA for the three months ended June 30, 2017 was $88.1 million, compared to $81.2 million for the three months ended June 30, 2016, an increase of 8.5%. The reconciliation of GAAP net cash provided by (used in) operating activities and net income to EBITDA and Adjusted EBITDA and additional cash flow information is set forth below in this release.

Reconciliation of EBITDA, Adjusted EBITDA and Additional Cash Flows Information

For the Three and Six-Month Periods Ended June 30, 2017 and 2016

(Unaudited)

We calculate EBITDA as net income before interest, taxes, depreciation and amortization. We calculate Adjusted EBITDA as net income before interest, taxes, depreciation and amortization, adjusted for (i) termination fees, (ii) impairment of long-lived assets, (iii) write-off of unsuccessful exploration activities, (iv) any mark-to-market gains or losses from accounting for derivatives, (v) merger and acquisition transaction cost, (vi) stock-based compensation, (vii) gain from extinguishment of liability, and (viii) gain on sale of subsidiary and property, plant and equipment. EBITDA and Adjusted EBITDA are not a measurement of financial performance or liquidity under accounting principles generally accepted in the United States of America and should not be considered as an alternative to cash flow from operating activities or as a measure of liquidity or an alternative to net earnings as indicators of our operating performance or any other measures of performance derived in accordance with accounting principles generally accepted in the United States of America. EBITDA and Adjusted EBITDA are presented because we believe they are frequently used by securities analysts, investors and other interested parties in the evaluation of a company’s ability to service and/or incur debt. However, other companies in our industry may calculate EBITDA and Adjusted EBITDA differently than we do.

The following tables reconcile net cash provided by (used in) operating activities and net income to EBITDA and Adjusted EBITDA for the three-month and six months periods ended June 30, 2017 and 2016.
