ORMAT TECHNOLOGIES REPORTS SECOND QUARTER 2026 FINANCIAL RESULTS

CONTINUED EXECUTION ON ORMAT'S GROWTH STRATEGY DROVE DOUBLE-DIGIT REVENUE GROWTH WHILE ADVANCING EGS DEVELOPMENT

HIGHLIGHTS

RENO, Nev., August 5, 2026 - Ormat Technologies, Inc. (NYSE: ORA) (the “Company” or “Ormat”), a leading geothermal and renewable energy company, today announced financial results for the second quarter ended June 30, 2026.

KEY FINANCIAL RESULTS

¹ See reconciliation table below

“Our second quarter results reflect the continued successful execution of our diversified growth strategy. We delivered double-digit revenue growth while expanding gross profit by more than 20%, reflecting the strength and balance of our three operating segments. Based on our strong first-half performance and positive momentum across our business, we are raising our full-year 2026 revenue and Adjusted EBITDA guidance," said Doron Blachar, Chief Executive Officer of Ormat.

Blachar continued, "Our Electricity segment built on its growth momentum during the quarter, driven by contributions from our Blue Mountain geothermal power plant acquired in June 2025, improved performance at our Olkaria and Puna power plants, and lower curtailments in the USA compared to the prior-year period. Our Energy Storage segment delivered another outstanding quarter, with revenues increasing nearly threefold year-over-year. The combination of new capacity additions, high asset availability and favorable merchant pricing highlights the value of our strategy of combining long-term contracted revenues with selective merchant exposure to maximize returns while maintaining disciplined risk management."

Blachar added, "Beyond our strong quarterly results, we continue to execute on the projects that will drive our growth. Since the start of the year, we expanded our generation portfolio by 155 MW with the addition of the Hoku solar and energy storage facility, the Shirk energy storage facility, the completion of the 5 MW Cove Fort upgrade and the recent commencement of commercial operations at our 10 MW Dominica geothermal power plant. Today, we have 202 MW of electricity generation projects under construction and development, all backed by long-term PPAs, together with 497 MW / 1,888 MWh of energy storage projects under construction and development, providing strong visibility into our continued growth. Combined with increasing demand for reliable renewable electricity and improving power pricing, these developments reinforce our confidence in achieving our long-term growth objectives."

EGS UPDATE

Blachar commented, “We continued to make significant progress on our EGS strategy during the quarter. On the subsurface side, we advanced both the SLB and Sage Geosystems pilot projects toward field execution, with each partnership taking concrete steps toward commercial-scale validation. At the Desert Peak project with SLB, we completed geophysical data acquisition, updated the subsurface model, advanced permitting and procurement of long-lead materials, and entered the final stages of vendor selection ahead of planned drilling in the fourth quarter of 2026. At the Sage Geosystems pilot, we selected a power plant in Nevada, advanced permitting activities, neared completion of procurement for drilling services and equipment and progressed engineering work to integrate the two-well EGS facility into the selected Ormat power plant.

We are also actively working to expand our substantial geothermal land position and water rights to support future EGS development, in addition to applying for new interconnections, recognizing that building a strong EGS pipeline will enable us to accelerate our project development.

On the surface technology side, we introduced our Ormega100 surface generation unit, a significant advancement in our ability to convert subsurface EGS resources into grid-scale power by connecting upstream development capabilities with downstream generation at an accelerated pace. Together with our growing pipeline of partnership opportunities, we anticipate that these initiatives position Ormat to accelerate the commercialization of EGS technology and capture increasing demand for next-generation geothermal power."

FINANCIAL HIGHLIGHTS

BUSINESS HIGHLIGHTS

2026 GUIDANCE

The Company provides a reconciliation of Adjusted EBITDA, a non-GAAP financial measure for the three and six months ended June 30, 2026. However, the Company does not provide guidance on net income and is unable to provide a reconciliation for its Adjusted EBITDA guidance range to net income without unreasonable efforts due to high variability and complexity with respect to estimating certain forward-looking amounts, the probable significance of which cannot be determined. These include impairments and disposition and acquisition of business interests, income tax expense, and other non-cash expenses and adjusting items that are excluded from the calculation of Adjusted EBITDA.

DIVIDEND

On August 5, 2026, the Company’s Board of Directors declared, approved, and authorized payment of a quarterly dividend of $0.12 per share pursuant to the Company’s dividend policy. The dividend will be paid on September 2, 2026, to stockholders of record as of the close of business on August 19, 2026. In addition, the Company expects to pay a dividend of $0.12 per share in the next quarter.

Reconciliation of EBITDA and Adjusted EBITDA

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; (viii) allowance for bad debts; and (ix) 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 and six months ended June 30, 2026, and 2025:

Reconciliation of Adjusted Net Income attributable to the Company's stockholders and Adjusted diluted EPS²

Adjusted Net Income attributable to the Company's stockholders and Adjusted diluted EPS are adjusted for one-time expense items that are not representative of our ongoing business and operations. The use of Adjusted Net income attributed to the Company's stockholders and Adjusted diluted EPS is intended to enhance the usefulness of our financial information by providing measures to assess the overall performance of our ongoing business.

The following tables reconcile Net income attributable to the Company's stockholders and Adjusted diluted EPS for the three and six months ended June 30, 2026, and 2025:

² Adjusted diluted EPS is computed based on adjusted net income attributable to the Company’s stockholders and diluted weighted-average shares outstanding before rounding. The individual components in the table are rounded to the nearest applicable unit; therefore, recalculation using the rounded amounts may not result in the adjusted diluted EPS presented.
