FINANCIAL CALENDAR / IMPRINT

Dear shareholders, employees, and business partners,

IONOS Group SE has made a successful start to the 2025 financial year. Revenue, EBITDA, and customer base have all increased further.

The customer base grew by around 80,000 to 6.40 million customers in the first quarter of 2025 (December 31, 2024: 6.32 million customers). Revenue increased by 19.7% to €446.3 million (Q1 2024: €373.0 million). Adjusted EBITDA increased by 23.8% to €131.0 million (Q1 2024: €105.8 million). The adjusted EBITDA margin improved accordingly to 29.4% (Q1 2024: 28.4%).

IONOS introduced segment reporting at the end of the 2024 financial year. The "Digital Solutions & Cloud" segment comprises the core business with revenues from the Web Presence & Productivity and Cloud Solutions business units as well as intercompany revenues with affiliated companies of the United Internet Group. The "AdTech" segment includes revenues from digital advertising and the domain trading platform.

Revenue in the Digital Solutions & Cloud segment increased by 7.3% to €329.6 million in the first quarter of 2025 (Q1 2024: €307.3 million) or by 7.8% excluding intercompany revenue. Adjusted EBITDA for the segment increased by 20.9% to €112.8 million (Q1 2024: €93.2 million).

We are currently seeing high demand for powerful and trustworthy infrastructures in the cloud business – especially from companies that value data security, transparency, and independence. This confirms the relevance of our solutions for a digitally sovereign economy in Europe and our positioning as a reliable partner.

In the lower-margin AdTech segment, revenues increased significantly by 77.7% to €116.7 million (Q1 2024: €65.7 million), starting from an exceptionally weak prior-year quarter and supported by a positive product transition.

Based on the better-than-expected business performance in the AdTech segment in the first three months, IONOS is specifying its forecast for the 2025 financial year and now expects currency-adjusted revenue of approximately €400 million in this segment (previous forecast: above the previous year's level; 2024: €312.2 million). In the medium term, the product changeover is also expected to have a positive impact on the segment's sustainable revenue and earnings development.

In its core business (Digital Solutions & Cloud segment), revenue adjusted for currency effects is expected to grow by approximately 8% (2024: €1,248.1 million), with an adjusted EBITDA margin of approximately 35% (2024: 32.9%).

Due to the positive development in the AdTech segment and continued cost discipline, we now expect adjusted EBITDA for the 2025 financial year to grow by approximately 15% to around €520 million (previous forecast: €510 million; 2024: €452.2 million).

INTERIM STATEMENT ON THE FIRST QUARTER 2025

Business Development

The Group's operating activities are divided into two business segments: "Digital Solutions & Cloud" and "AdTech."

The Digital Solutions & Cloud segment comprises the Web Presence & Productivity and Cloud Solutions business units. In the Web Presence & Productivity business unit, IONOS offers its customers customized products that enable them to quickly and easily set up an online presence. The Cloud Solutions offering includes both public cloud and private cloud solutions with a wide range of services in the areas of Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS).

The AdTech segment (previously referred to as the "Aftermarket" unit) represents the secondary market for the use and trading of domains. The product portfolio is primarily marketed through the Sedo brand.

On the one hand, IONOS acts as a domain parking provider, placing automated and targeted advertising on the domains, operating the technical platform, and optimizing traffic. In the parking segment, revenues are increasingly being generated with the "RSOC" (Related Search On Content) product provided by Google, for which IONOS operates a platform for monetizing traffic via advertising links. On the other hand, IONOS offers suitable solutions under the Sedo brand via its own marketplace, where domains can be offered at attractive prices or sold in an auction format.

As part of group-wide standardization measures, some products were reclassified and reassigned. In addition, the AdTech segment is reported for the first time, having been reported in the Web Presence & Productivity business unit in the previous year.

Development in the Digital Solutions & Cloud segment

In the Digital Solutions & Cloud segment, the focus in the first three months of the financial year 2025 remained on acquiring new customers.

Overall, the number of customers increased by approximately 80,000 to a total of approximately 6.4 million customers.

Due to customer growth and successful upselling and cross-selling, revenue in the Digital Solutions & Cloud segment increased by 7.3% from €307,305k in the previous year to €329,641k. Further growth in virtual private server products and in the enterprise cloud business with large customers also contributed to this increase in the Cloud Solutions business unit.

EBITDA increased by 19.9% to €106,389k due to revenue growth and a higher margin resulting from scale and price effects.

Adjusted for special items, operating segment EBITDA increased by 20.9% year-on-year in the first three months, from €93,241k to €112,772k.

Development in the AdTech segment

The growth from the second half of 2024 in the AdTech segment continued to accelerate in the first three months, resulting in a 77.7% year-on-year increase in revenue.

Mainly due to higher margins, combined with strong growth in the first three months, EBITDA increased by 45.1% compared with the previous year.

Position of the Group

In the first three months of 2025, there were no significant acquisition and divestment effects on revenue and EBITDA at Group and segment level.

Earnings position

Revenue from contracts with customers increased by +20.5% from €361,487k in the first three months of 2024 to €435,629k in the first three months of 2025. The increase in revenue is mainly attributable to the continued positive development of new customer business, higher revenue from cross-selling and upselling to existing customers and the strong increase in AdTech revenue compared to the same quarter of the previous year. In addition, the rising level of revenue is also driven by the further expansion of our business activities in the Cloud Solutions product area.

EBITDA showed a positive development in the first three months, rising by €23,325k to €124,627k (+23.0%), despite temporarily higher marketing expenses (+13.0%) compared to the same period last year and increased expenses for purchased services (+39.6%), which is primarily attributable to the strong growth of the AdTech business compared to the same quarter last year.

The EBITDA margin increased year-on-year from 27.2% in the first three months to 27.9%.

Adjusted EBITDA increased as planned in the first three months of 2025, with marketing expenses shifted over time from €105,807k by 23.8% to €131,010k. At 29.4%, the adjusted EBITDA margin in the first three months was above the previous year's margin of 28.4%.

EBIT increased by 31.0% from €74,158k to €97,166k, thus developing positively as a result of the effects described above.

At 21.8%, the EBIT margin for the first three months of 2025 was above the previous year's margin of 19.9%.

Costs of sales increased by +24.5% to €226,583k in the first three months of 2025 compared to the previous year, with revenue rising by +19.7%, resulting in an increase in the gross margin from 48.8% to 50.8%. This development is primarily attributable to the increased volume of Sedo's AdTech business in conjunction with a margin increase.

Selling expenses increased by +7.5% (€6,550k) in the first three months of 2025 compared with the previous year. This was mainly due to a temporary increase in purchased marketing services (€4,571k or 13.0% compared with the previous year). As a result of the developments described above, the sales expense ratio fell by -2.4 percentage points in the first three months.

Administrative expenses increased by +8.1% (€2,002k) in the first three months of 2025 compared with the previous year. This was primarily due to higher personnel expenses.

The net position from other operating income and expenses increased by €3,409k to €3,738k (previous year: €329k).

The financial result amounted to €-23,623k (previous year: €-24,398k) and is characterized by a valuation adjustment of the purchase price liability in connection with the acquisition of STRATO GmbH (-€10,347k; previous year: -€8,324k). In addition, interest expenses decreased as a result of the ongoing repayment of the loan from United Internet AG (in the first three months of 2025: €-12,393k; previous year: €-15,662k).

Earnings per share (EPS) amounted to €0.37 as of March 2025, compared with €0.24 as of March 2024. As in the previous year, the annual result was significantly influenced by expenses from the change in a purchase price liability (EPS effect: €-0.07; previous year: €-0.06). Adjusted EPS (excluding the effect on earnings from the measurement of the contingent purchase price liability) amounted to €0.44 in the first three months of 2025 and €0.31 in the first three months of the previous year (+41.9%).

Net cash flows from operating activities amounted to €77,242k, down €8,216k on the previous year (previous year: €85,458k). This development is mainly attributable to payments for employee participation programs in the first three months of 2025. This was offset by the continued positive business development.

During the reporting period, net cash flows from investing activities amounted to €-32,713k, which is below the corresponding figure for the previous year (€-68,692k). Payments from surplus liquidity invested with United Internet AG amounted to €-18,301k, which is €-34,727k below the previous year's level. Investments in intangible assets and property, plant, and equipment also decreased by €-1,060k to €- 14,875k (previous year: €-15,935k).

At IONOS, free cashflow is defined as net cash inflows from operating activities, less investments in intangible assets and property, plant and equipment, plus cash inflows from disposals of intangible assets and property, plant and equipment, and including the repayment portion of lease liabilities, which have been reported in net cash flows from financing activities since fiscal year 2019. Free cash flow in March 2025 was €59,129k, compared to €66,153k in March 2024, mainly due to the effects described above.

As of March 2025, cash flow from financing activities amounted to €-32,283k from the acquisition of treasury shares (previous year: €0k). Interest payments on the loan to United Internet AG amounted to €- 4,337k in March, down €3,894k on the previous year (March: €-8,231k). This effect is mainly due to the further repayment of the loan to United Internet AG.

Cash and cash equivalents amounted to €34,305k as of March 31, 2025 (previous year: €30,180k).

Asset position

At €1,680,483k, total assets were slightly higher than the total assets as of December 31, 2024 (€1,643,586k).

The increase in current assets of €48,857k is mainly due to the €18,504k increase in receivables from related parties. This item includes cash pool receivables, which increased by €18,301k as a result of the build-up of surplus liquidity invested with United Internet AG. In addition, trade receivables are €12,930k higher than the respective balances at the end of the fiscal year.

Current liabilities increased by a total of €27,814k compared with the end of financial year 2024. Other financial liabilities increased by €24,130k, mainly due to the higher subsequent valuation of a purchase price liability in connection with the acquisition of STRATO GmbH. Current liabilities due to banks increased by €9,214k due to interest accruals. Income tax liabilities decreased by €7,335k.

Non-controlling interests	149	144	3,4%
Total equity	168,480	158,760	6,1%

The issued capital of the Group rose from €158,760k as of December 31, 2024, to €168,480k as of March 31, 2025. The increase is mainly due to the change in reserves. In the first three months, the allocation of consolidated net income in the amount of €50,709k and the valuation and exercise of employee participation programs in the amount of €-15,587k were responsible for this change. This was offset by the acquisition of treasury shares, which are to be deducted from equity.

On May 8, 2024, the Management Board of IONOS Group SE, with the approval of the Supervisory Board and based on the authorization of the Extraordinary General Meeting on January 26, 2023, to acquire Treasury shares, initially decided to acquire up to 850,000 Treasury shares via the stock exchange. This corresponds to approximately 0.6% of the issued capital of €140,000k. The buyback program is to be carried out from mid-May 2024 and no later than February 28, 2025.

As part of the share buyback program, IONOS Group SE acquired a total of 850,000 Treasury shares for the first time in the period from May 17 to July 25, thereby completing the share buyback program. The purchase price excluding transaction costs amounted to €22,319k.

On January 21, 2025, the Management Board of IONOS Group SE, with the approval of the Supervisory Board and based on the authorization of the extraordinary General Meeting of January 26, 2023, resolved to launch a share buyback program and acquire up to 1,500,000 Treasury shares (corresponding to approximately 1.1% of the issued capital of €140,000k) via the stock exchange. The total volume of the buyback program amounts to up to €40 million (excluding incidental acquisition costs).

The share buyback program is to be carried out by December 31, 2025, at the latest. The share buyback will be used, among other things, to settle claims arising from employee participation programs, but may in principle be used for all purposes specified in the authorization granted by the Annual General Meeting.

By March 31, 2025, IONOS Group SE had acquired 1,326,244 treasury shares. The purchase price, excluding incidental acquisition costs, amounted to €32,283k.

As part of the employee stock ownership program, 374,176 treasury shares were issued in the first three months (previous year: 386,435 treasury shares).

Net debt (i.e., the balance of liabilities to related parties and banks, receivables from related parties, and cash and cash equivalents) decreased by €12,934k from €855,292k as of December 31, 2024, to €842,358k as of March 31, 2025.

Management Board's overall assessment of the business situation

In the first three months of financial year 2025, the company further increased its revenue, adjusted EBITDA and customer numbers.

Revenue in the Digital Solutions & Cloud segment increased by 7.3% to €329.6 million in the first quarter of 2025 (Q1 2024: €307.3 million) or by 7.8% after adjusting for intercompany revenue with the United Internet Group. Adjusted EBITDA for the segment increased by 20.9% to €112.8 million (Q1 2024: €93.2 million).

Based on the better-than-expected business performance in the AdTech segment in the first three months, the company specifies its forecast for the 2025 financial year and now expects currency-adjusted revenue of approximately €400 million in this segment (previous forecast: above the previous year's level; 2024: €312.2 million). In the medium term, the product changeover is also expected to have a positive impact on the segment's sustainable revenue and earnings development.

Due to the positive development in the AdTech segment and continued cost discipline, adjusted EBITDA for the 2025 financial year is now expected to grow by approximately 15% to around €520 million (previous forecast: €510 million; 2024: €452.2 million).

Based on the revenue and earnings figures achieved in the first three months of 2025 and in view of the investments made in sustainable corporate development, the Management Board believes that the company remains very well positioned for future growth. Based on the forecast continuation of overall economic growth in IONOS' core sales markets, the ongoing digitalization and increasing importance of artificial intelligence, and the stable business model based primarily on electronic subscriptions, the Management Board continues to expect a positive development of the key financial and non-financial performance indicators.

Subsequent events

No events of particular significance occurred at IONOS after the balance sheet date of March 31, 2025, that would have a material impact on the Group's financial position, results of operations, or cash flows and would require disclosure in accordance with the accounting and reporting principles applied by the Group.

Risk and opportunity report

IONOS' risk and opportunity policy is geared toward maintaining and sustainably increasing the value of the company by seizing opportunities and identifying and managing risks at an early stage. Risk and opportunity management regulates the responsible handling of uncertainties that are always associated with entrepreneurial activity.

Overall statement by the Executive Board on the Group's risk and opportunity situation

The assessment of the overall risk situation is the result of a consolidated review of all significant risk areas and individual risks, taking into account their interdependencies.

The overall risk and opportunity situation remained largely stable in the first three months of 2025 compared with the risk and opportunity reporting in the 2024 consolidated financial statements.

Compared to December 31, 2024, there were no changes in the risk areas during the first quarter of 2025.

No risks that could significantly affect IONOS were identified during the reporting period or at the time this quarterly report was prepared, either from individual risk positions or from the overall risk situation.

IONOS addresses these risks through the continuous expansion of its risk management system and, where appropriate, minimizes them by implementing specific measures.

Forecast Report

2025 Forecasts for financial year 2025 specified

Based on the better-than-expected business performance in the AdTech segment in the first three months, the company is specifying its forecast for the 2025 financial year and now expects currencyadjusted revenue of approximately €400 million in this segment (previous forecast: above the previous year's level; 2024: €312.2 million). In the medium term, the product changeover is also expected to have a positive impact on the segment's sustainable revenue and earnings development.

Forward-looking statements and forecasts

This quarterly report contains forward-looking statements based on the current expectations, assumptions, and forecasts of the Management Board of IONOS Group SE and the information currently available to it. Forward-looking statements are subject to various risks and uncertainties and are based on expectations, assumptions, and forecasts that may not prove to be accurate in the future. IONOS does not guarantee that the forward-looking statements will prove to be correct and does not undertake any obligation to update or revise the forward-looking statements contained in this interim report.

Notes to the Quarterly Statement

Significant accounting, measurement and consolidated principles

The quarterly report of IONOS Group SE as of March 31, 2025, like the consolidated financial statements as of December 31, 2024, has been prepared in accordance with International Financial Reporting Standards (IFRS) as adopted by the European Union (EU).

The quarterly report does not constitute interim financial reporting within the meaning of IAS 34. The accounting policies applied in this quarterly report are consistent with those applied in the previous year, with the exception of the new standards that are required to be applied, and should be read in conjunction with the consolidated financial statements as of December 31, 2024.

Mandatory adoption of new accounting standards

The following standards will be mandatory in the EU for the first time for the financial year beginning on January 1, 2025:

Standard		Mandatory for fiscal
		years beginning on or	Endorsed by EU
		after	Commission
IAS 21	Amendment: insufficient convertibility of a currency	January 1, 2025	Yes

The first-time application of the new accounting standards did not have any significant impact on the quarterly financial statement.

Use of estimates and assumptions

In preparing this quarterly statement, management makes judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the disclosure of contingent liabilities at the reporting date. However, the uncertainty associated with these assumptions and estimates could lead to results that may require material adjustments to the carrying amounts of the assets or liabilities affected in the future.

Miscellaneous

This quarterly report includes all significant subsidiaries and associated companies.

The scope of consolidation remained unchanged compared with the consolidated financial statements as of December 31, 2024

This Interim Statement was not audited in accordance with §317 of the German Commercial Code (HGB) or reviewed by an auditor.
