Executive Commentary

Enric Asuncion, CEO of Wallbox, said, “2023 was a year of transitions at Wallbox. The EV adoption curve is in the process of crossing the chasm, which combined with higher interest rates and increased channel inventory, to drive variability in our forecasts and results. While those disruptions made for a challenging year, we focused on executing our long-term strategic plan, and achieved several outstanding milestones, highlighting our strength and resilience. We

launched innovative new products, streamlined our cost base to accelerate our path to profitability, forged meaningful new partnerships with global brands including Generac, Costco, Kia, and Free2Move. With ABL, we acquired the leading EV charging company in Germany, positioning us at the forefront of the largest European market, and we added almost €143 million of cash to our balance sheet.”

Mr. Asuncion continued, “We are more lean, focused and determined than ever before, and we believe we are better positioned to lead in the markets in which we compete. The opportunities are compelling, and include our DC portfolio coming to North America, integrating ABL into our global channels, advancing our partnership with Generac, and so much more. We believe 2024 will be a year of growth and profitability for Wallbox, and we are excited to show customers, partners, and investors what we’re truly capable of.”

Conference Call Information

Wallbox NV will host a conference call to discuss the results and provide a business update at 8:00 AM Eastern Time today, February 28, 2024.

Except as required by law, Wallbox disclaims any obligation to update or revise, or to publicly announce any update or revision to, any of the forward-looking statements, whether as a result of new information, future events or otherwise.

Non-IFRS **** Financial **** Measures

Wallbox reports its financial information required in accordance with the International Financial Reporting Standards (“IFRS”). This release includes financial measures not based on IFRS, including Adjusted EBITDA (the “Non-IFRS Measure”). See the definitions set forth below for a further explanation of these terms.

Wallbox defines EBITDA as loss for the period before income tax credit, financial income, interest expenses, amortization and depreciation and share of profit of equity-accounted investees. We define Adjusted EBITDA as net income (loss) before depreciation and amortization, provision (benefit) for income taxes and interest expense adjusted to take account of the impact of certain non-cash and other items that we do not consider in our evaluation of our ongoing operating performance. These non-cash and other items include, but not are limited to: change in fair value of convertible bonds and derivative warrants liabilities, share listing expenses, foreign exchange gains/(losses), share based payment plan transaction costs related to the Business Combination, certain one-time expenses related to a reduction in force initiated in January 2023, certain non-cash expenses related to the ESPP plan launched in January 2023, and other items outside the scope of our ordinary activities. Management uses these Non-IFRS Measures as measurements of operating performance because they assist management in comparing the Company’s operating performance on a consistent basis, as they remove the impact of items not directly resulting from the Company’s core operations; for planning purposes, including the preparation of management’s internal annual operating budget and financial projections; to evaluate the performance and effectiveness of our strategic initiatives; and to evaluate the Company’s capacity to fund capital expenditures and expand its business.

The Non-IFRS Measures may not be comparable to similar measures disclosed by other companies, because not all companies and analysts calculate these measures in the same manner. We present the Non-IFRS Measures because we consider them to be important supplemental measures of our performance, and we believe they are frequently used by securities analysts, investors and other interested parties in the evaluation of companies. Management believes that investors’ understanding of our performance is enhanced by including the Non-IFRS Measures as a reasonable basis for comparing our ongoing results of operations. By providing the Non-IFRS Measures, together with reconciliations to IFRS, we believe we are enhancing investors’ understanding of our business and our results of operations, as well as assisting investors in evaluating how well we are executing our strategic initiatives.

Items excluded from the Non-IFRS Measures are significant components in understanding and assessing financial performance. The Non-IFRS Measures have limitations as analytical tools and should not be considered in isolation, or as an alternative to, or a substitute for loss for the period, revenue or other financial statement data presented in our consolidated financial statements as indicators of financial performance. Some of the limitations are: such measures do not reflect revenue related to fulfillment, which is necessary to the operation of our business; such measures do not reflect our expenditures, or future requirements for capital expenditures or contractual commitments; such measures do not reflect changes in our working capital needs; such measures do not reflect our share based payments, income tax benefit/(expense) or the amounts necessary to pay our taxes; although depreciation and amortization are not included in the calculation of Adjusted EBITDA, the assets being depreciated and amortized will often have to be replaced in the future and such measures do not reflect any costs for such replacements; and other companies may calculate such measures differently than we do, limiting their usefulness as comparative measures.

Due to these limitations, Adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business and are in addition to, not a substitute for or superior to, measures of financial performance prepared in accordance with IFRS. In addition, the Non-IFRS Measures we use may differ from the non-IFRS financial measures used by other companies and are not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with IFRS. Furthermore, not all companies or analysts may calculate similarly titled measures in the same manner. We compensate for these limitations by relying primarily on our IFRS results and using the Non-IFRS Measures only as supplemental measures.
