HIGHLIGHTS

RENO, Nev. May 7, 2025, Ormat Technologies, Inc. (NYSE: ORA) (the “Company” or “Ormat”), a leading renewable energy company, today announced financial results for the first quarter ended March 31, 2025.

KEY FINANCIAL RESULTS

¹ Net Income attributable to the Company’s stockholder

² See reconciliation table below

“Ormat had a strong start to 2025, achieving a 2.5% increase in revenue, a 4.6% rise in net income attributable to the Company’s stockholders, and a 6.4% increase in adjusted EBITDA. This growth was driven by improved performance in both our Product and Storage segments,” said Doron Blachar, Chief Executive Officer of Ormat Technologies. “Our Storage segment benefited from new capacity added over the last 12 months and from higher merchant prices in the PJM market. We expect continued good performance throughout 2025 as we transition our Storage segment to a more predictable portfolio designed to maximize profitability.”

“While our Electricity segment experienced a slight year-over-year decline in the quarter due to previously disclosed curtailments in California and Nevada, the balance of our geothermal operations delivered a consistent, solid performance. We have several projects under development that we anticipate will reach commercial operation by the end of 2025, which we expect will deliver solid generation growth and further strengthen our earnings trajectory. Additionally, we believe that the potential easing of project permitting timelines combined with increased focus on geothermal exploration will further support our growth in the segment, expand our revenues, and help us achieve our long-term targets.”

“I am pleased to announce that Ormat signed an agreement to acquire the Blue Mountain geothermal power plant from Cyrq Energy for $88 million, subject to standard working capital adjustments. The 20 MW facility, located in Humboldt County, was built using Ormat technology, features an existing 51 MW interconnection capacity and a Power Purchase Agreement (PPA) with NV Energy (NVE) that expires at the end of 2029. Following the acquisition, Ormat plans to upgrade the power plant, increasing its capacity by 3.5 MW. Additionally, subject to permit and PPA approval, Ormat intends to add a 13 MW solar facility to support the plant's auxiliaries. The acquisition is anticipated to close towards the end of the second quarter. This acquisition underscores Ormat's capability to strategically expand and enhance assets in the U.S., leveraging our advanced technology and expertise to optimize performance and efficiency. The planned upgrades and solar addition demonstrate our commitment to innovation and maximizing renewable energy output, contributing to a sustainable future.”

Blachar continued, “The demand for electricity, particularly from baseload renewable sources, remains strong, and we continue to observe high PPA pricing in the Electricity Segment, and increased Resource Adequacy (RA) pricing in the Storage Segment. Regarding the recent reciprocal tariffs, we anticipate a limited short-term impact on our Storage Segment as we have already procured batteries for all projects currently under construction. Additionally, our Electricity Segment operations and project development have limited exposure to China, mitigating potential adverse effects from the tariffs. Ormat remains committed to delivering reliable and sustainable energy solutions and enhancing shareholder value. We will continue navigating this fluid regulatory environment with a focus on maintaining our growth trajectory and supporting the transition to a cleaner energy future.”

Reconciliation of EBITDA and Adjusted EBITDA

For the Three Months Ended March 31, 2025, and 2024

We calculate EBITDA as net income before interest, taxes, depreciation, amortization and accretion. We calculate Adjusted EBITDA as net income before interest, taxes, depreciation, amortization and accretion, adjusted for (i) mark-to-market gains or losses from accounting for derivatives not designated as hedging instruments; (ii) stock-based compensation, (iii) merger and acquisition transaction costs; (iv) gain or loss from extinguishment of liabilities; (v) cost related to a settlement agreement; (vi) non-cash impairment charges; (vii) write-off of unsuccessful exploration and storage activities; and (viii) other unusual or non-recurring items. We adjust for these factors as they may be non-cash, unusual in nature and/or are not factors used by management for evaluating operating performance. We believe that presentation of these measures will enhance an investor’s ability to evaluate our financial and operating performance. EBITDA and Adjusted EBITDA are not measurements of financial performance or liquidity under accounting principles generally accepted in the United States, or U.S. GAAP, 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 U.S. GAAP. Our Board of Directors and senior management use EBITDA and Adjusted EBITDA to evaluate our financial performance. However, other companies in our industry may calculate EBITDA and Adjusted EBITDA differently than we do.

The following table reconciles net income to EBITDA and Adjusted EBITDA for the three months ended March 31, 2025, and 2024:
