Management Commentary

“We are pleased to report a 27.3% sequential increase in quarterly revenues, making it our seventh sequential increase in a row,” said Zvi Alon, Chairman and CEO of Tigo. “While the fourth quarter is typically a seasonally slower period for our industry, we expect revenues to remain largely in line with the third quarter, supported by continued strong demand for our products and a healthy backlog as we close out the year.”

“In the third quarter, we saw strong growth in the EMEA and Americas regions, which comprised 70% and 26%, respectively, of our revenue. Noteworthy, we performed exceptionally well in the U.S., as sales grew by approximately 68% sequentially from the second quarter of 2025 as we continue to make inroads in the repower market. We expect our manufacturing and marketing partnership with EG4 Electronics to further increase our performance in our domestic market.”

“We are pleased to report a return to GAAP operating profitability this quarter, following our achievement of adjusted EBITDA profitability at the end of the second quarter,” stated Bill Roeschlein, Chief Financial Officer of Tigo. “Supported by a measured use of our at-the-market (ATM) program, which concluded this month, we increased cash on hand to $40.3 million at quarter-end.”

	●	Revenues totaled $30.6 million, a 115.0% increase from $14.2 million. On a sequential quarter basis, revenues increased by 27.3% compared to the second quarter of 2025.

	●	Gross profit totaled $13.1 million, or 42.7% of net revenue, compared to gross profit of $1.8 million, or 12.5% of net revenue.

These forward-looking statements are based upon the current beliefs and expectations of Tigo’s management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are difficult to predict and generally beyond our control. Actual results and the timing of events may differ materially from the results anticipated in these forward-looking statements.

In addition to factors previously disclosed, or that will be disclosed in, our reports filed with the SEC, factors which may cause actual results to differ materially from current expectations include, but are not limited to, our capital requirements and our ability to meet our future liquidity requirements and continue as a going concern; our indebtedness and liabilities and our ability to pay amounts when due under our existing indebtedness; our ability to effectively develop and sell our product offerings and services, our ability to compete in the highly-competitive and evolving solar industry; our failure to meet the continued listing requirements of Nasdaq which could result in a delisting of our securities; our ability to manage risks associated with U.S. and global geopolitical and macroeconomic conditions including the potential softening of the economy, seasonal trends and the cyclical nature of the solar industry, including any periods of prolonged downturn; whether we continue to grow our customer base and expand our market share; whether we continue to develop new products and innovations to meet constantly evolving customer demands; the timing and level of demand for our solar energy solutions; changes in government subsidies and economic incentives, including tax incentives, for solar energy solutions; trade tariffs and other trade barriers that could directly affect us, our customers and the solar industry; our ability to forecast our customer demand and manufacturing requirements, and manage our inventory; our ability to acquire or make investments in other businesses, patents, technologies, products or services to grow the business and realize the anticipated benefits therefrom; our ability to respond to fluctuations in foreign currency exchange rates and political unrest and regulatory changes in the U.S. and international markets into which we expand or otherwise operate in; our failure to attract, hire retain and train highly qualified personnel in the future; and if we are unable to maintain key strategic relationships with our partners and distributors.

Actual results, performance or achievements may differ materially, and potentially adversely, from any projections and forward-looking statements and the assumptions on which those forward-looking statements are based. There can be no assurance that the forward-looking statements contained herein are reflective of future performance to any degree. You are cautioned not to place undue reliance on forward-looking statements as a predictor of future performance as projected financial information and other information are based on estimates and assumptions that are inherently subject to various significant risks, uncertainties and other factors, many of which are beyond our control. All information set forth herein speaks only as of the date hereof, and we disclaim any intention or obligation to update any forward-looking statements as a result of new information, future developments or otherwise occurring after the date of this communication.

Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with GAAP, we use the following non-GAAP financial measure: adjusted EBITDA. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

We use adjusted EBITDA for financial and operational decision-making and as a means to evaluate period-to-period comparisons. We define adjusted EBITDA, a non-GAAP financial measure, as earnings (loss) before interest and other expenses, net, income tax expense (benefit), depreciation and amortization, as adjusted to exclude stock-based compensation and merger transaction related expenses. We believe that adjusted EBITDA provides helpful supplemental information regarding our performance by excluding certain items that may not be indicative of our core business operating results. We believe that both management and investors benefit from referring to adjusted EBITDA in assessing our performance and when planning, forecasting, and analyzing future periods. Adjusted EBITDA also facilitates management’s internal comparisons to our historical performance and comparisons to our competitors’ operating results. We believe adjusted EBITDA is useful to investors both because they (i) allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (ii) are used by our institutional investors and the analyst community to help them analyze the health of our business.

The items excluded from adjusted EBITDA may have a material impact on our financial results. Certain of those items are non-recurring, while others are non-cash in nature. Accordingly, adjusted EBITDA is presented as supplemental disclosure and should not be considered in isolation of, as a substitute for, or superior to, the financial information prepared in accordance with GAAP.

There are a number of limitations related to the use of non-GAAP financial measures. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures and evaluating these non-GAAP financial measures together with their relevant financial measures in accordance with GAAP.

We refer investors to the reconciliation adjusted EBITDA to net income (loss) included below. A reconciliation for adjusted EBITDA provided as guidance is not provided because, as a forward-looking statement, such reconciliation is not available without unreasonable effort due to the high variability, complexity, and difficulty of estimating certain items such as charges to stock-based compensation expense and currency fluctuations which could have an impact on our consolidated results.
