Exhibit 99.1

SolarEdge Announces Second Quarter 2026 Financial Results

Revenue of $346.2 million, representing 20% growth year-over-year

Sixth consecutive quarter of gross margin expansion  year-over-year

MILPITAS, Calif. — August 5, 2026 — SolarEdge Technologies, Inc. (Nasdaq: SEDG), a global leader in smart energy technology, today announced its financial results for the second quarter ended June 30, 2026.

“Our second-quarter results mark an important milestone in SolarEdge’s turnaround,” said Shuki Nir, CEO of SolarEdge. “Revenue grew 20% year over year, GAAP operating loss narrowed significantly, and we returned to non-GAAP operating profitability for the first time since the second quarter of 2023, while continuing to generate positive free cash flow. Strong demand in Europe combined with strength in U.S. C&I, more than offset industry-wide softness in U.S. residential, driving overall year-over-year growth. We are focused on building on this momentum by scaling the Nexis platform in our core markets and continuing to advance the SolarEdge SST to address the significant opportunity in AI factories.”

Second Quarter 2026 Financial Highlights

(In millions, except percentages)

Outlook for the Third Quarter of 2026

The Company provides the following guidance for the third quarter ending September 30, 2026. This guidance does not include any significant pull-forward of revenue and excludes potential IEEPA  refunds in the third quarter.  When including the $11.5 million of IEEPA refunds we received in July, the midpoint of our guidance implies a non-GAAP operating profit in the third quarter.

*Non-GAAP gross margin and Non-GAAP operating expenses are non-GAAP financial measures, and these forward-looking measures have not been reconciled to the most comparable GAAP outlook because it is not possible to do so without unreasonable efforts due to the uncertainty and potential variability of reconciling items, which are dependent on future events and often outside of management’s control and which could be significant. Because such items cannot be reasonably predicted with the level of precision required, we are unable to provide outlook for the comparable GAAP measures. Forward-looking estimates of Non-GAAP gross margin and Non-GAAP operating expenses are made in a manner consistent with the relevant definitions and assumptions noted herein and in our filings with the SEC.

Use of Non-GAAP Financial Measures

To provide investors and others with additional information regarding SolarEdge’s results, SolarEdge has disclosed in this earnings release the following non-GAAP financial measures: non-GAAP revenue, non-GAAP operating income (loss), non-GAAP operating expenses, non-GAAP gross margin, non-GAAP net income (loss), non-GAAP net earnings (loss) per share, and non-GAAP net free cash flow. SolarEdge has provided a reconciliation of each non-GAAP financial measure used in this earnings release to the most directly comparable GAAP financial measure below. These non-GAAP financial measures differ from GAAP in that they exclude stock-based compensation, amortization and impairment of acquired intangible assets, restructuring and impairment charges, acquisition, disposition and other items, certain litigation and other contingencies, amortization of debt issuance cost, non-cash interest expense and non-cash revenue recognized from significant financing component, certain foreign currency exchange rates, gains and losses on investments, income and losses from equity method investments and discrete items that impacted our GAAP tax rate. Our non-GAAP financial measures also reflect the application of our non-GAAP tax rate.

SolarEdge’s management uses these non-GAAP financial measures to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, for short- and long-term operating plans, to calculate bonus payments and to evaluate SolarEdge’s financial performance, the performance of its individual functional groups and the ability of operations to generate cash. Management believes these non-GAAP financial measures reflect SolarEdge’s ongoing business in a manner that allows for meaningful period-to-period comparisons and analysis of trends in SolarEdge’s business, as they exclude charges and gains that are not reflective of ongoing operating results. Management also believes that these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating SolarEdge’s operating results and future prospects from the same perspective as management and in comparing financial results across accounting periods.

The use of non-GAAP financial measures has certain limitations because they do not reflect all items of income and expense that affect SolarEdge’s operations. These non-GAAP financial measures should be considered in addition to, not as a substitute for or in isolation from, measures prepared in accordance with GAAP and should not be considered measures of SolarEdge’s liquidity. Further, these non-GAAP measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore comparability may be limited. Management encourages investors and others to review SolarEdge’s financial information in its entirety and not rely on a single financial measure.
