Company Reiterates Full-Year 2015 Revenue and Adjusted EBITDA Guidance

RENO, Nevada, August 3, 2015 -- Ormat Technologies, Inc. (NYSE: ORA) today announced financial results for the second quarter ended June 30, 2015.

Second Quarter Highlights and Recent Developments:

Isaac Angel, chief executive officer of Ormat, stated, “Our balanced business model enabled Ormat to deliver another quarter of solid, double-digit revenue growth largely driven by 38.0% growth from our Product segment. We essentially matched last year’s revenue in our Electricity segment, mainly due to the McGinness Hills complex performance, overcoming lower oil and natural gas prices, as well as reduced generation at Puna due to last summer’s hurricane, which impacted our revenue in this segment. The enhancements implemented in our power plants that improved the efficiency of our operating portfolio along with the new capacity that came on line increased the margins in the Electricity segment despite the significant impact of the lower oil and natural gas prices on our revenue. Higher revenue and improvements in our consolidated gross margin drove a 27.0% increase in our operating income excluding an $8.1 million write off in the second quarter of 2014, demonstrating again the strength of our balanced business model.”

“We remain confident in the multi-year plan we outlined at our analyst day in March,” continued Mr. Angel. “We are focused on expanding our geographic reach and broadening our technology offering with a vision to position Ormat as a leading provider of renewable energy. We remain excited about the growing number of opportunities before us and believe the tailwinds expected from the potential PTC extension and other regulatory initiatives in the regions we are targeting, will complement our efforts.”

Guidance

Mr. Angel added, “Our guidance assumes the continued impact on our results due to lower oil and natural gas prices, which translates to a $28.6 million reduction in revenues compared to last year. However, we reiterate our 2015 revenue guidance and expect electricity segment revenues to be between $380.0 million and $390.0 million, and product segment revenues to be between $180.0 million and $190.0 million. We reiterate our 2015 Adjusted EBITDA guidance of $280.0 to $290.0 million for the full year, which is also impacted by current oil and natural gas prices. We expect Northleaf’s annual portion of the adjusted EBITDA guidance to be approximately $14.0 million.”

Second Quarter Financial Summary 

Total revenues for the three months ended June 30, 2015 were $140.5 million, an increase of 10.1% compared to $127.6 million for the three months ended June 30, 2014. Electricity revenues were $90.9 million for the quarter compared to $91.7 million in the second quarter last year. Product revenues increased 38.0% to $49.6 million for the second quarter of 2015, from $35.9 million in the second quarter last year.

The slight decrease in the electricity segment was primarily attributable to lower generation at the Puna power plant due to well field maintenance and lower energy rates resulting from the decrease in oil prices as well as lower revenues in some of Ormat’s power plants due to lower natural gas prices. The decrease was offset by the commencement of operations of second phase of the McGinness Hills power plant in Nevada, which began commercial operation in February 2015.

The company reported net income attributable to the company’s shareholders of $14.4 million or $0.28 per share (diluted) in the second quarter of 2015 compared to $9.1 million or $0.20 per share for the second quarter of 2014. The net income includes a $1.7 million related loss from extinguishment of a liability resulting from the repurchase of a portion of the OFC Senior Secured Notes as well as non-recurring and non-operating expenses of $0.4 million associated with due diligence related to a potential M&A transaction that management ultimately decided not to pursue.

Adjusted EBITDA for the three months ended June 30, 2015 was $67.8 million, compared to $61.8 million for the three months ended June 30, 2014 an increase of 9.7%. The reconciliation of GAAP net cash provided by operating activities and net income to EBITDA and Adjusted EBITDA and additional cash flow information is set forth below in this release.

On August 3, 2015, ORMAT’s Board of Directors approved a payment of a quarterly dividend of $0.06 per share. The dividend will be paid on September 2, 2015 to shareholders of record as of the close of business on August 18, 2015. In addition, the company expects to pay quarterly dividends of $0.06 per share in the next quarter.

Reconciliation of EBITDA, Adjusted EBITDA and Additional Cash Flows Information

For the Six and Three-Month Period Ended June 30, 2015 and 2014

(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, and (vii) gain from extinguishment of liability. 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 operating activities and net income to EBITDA and Adjusted EBITDA for the six and three-month period ended June 30, 2015 and June 30, 2014:
