CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING STATEMENTS

This quarterly report on Form 6-K contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that reflect the current views of Stevanato Group S.p.A. (“we”, “our”, “us”, “Stevanato Group”, the “Company” and, together with its subsidiaries, the “Group”). These forward-looking statements include, or may include, words such as “anticipate,” "assumes," "believe," "derive," "drive," "estimated," "expect," "forecast," "foreseeable," "future," "growing," "increase," "may," "plan," “potential,” “remain,” “to be,” “will,” "would," and other similar terminology. Forward-looking statements contained in this report include, but are not limited to, statements about: our future financial performance, including our revenue, operating expenses and our ability to maintain profitability and operational and commercial capabilities; our expectations regarding the development of our industry and the competitive environment in which we operate; the expansion of our plants and sites, and our expectations related to our capacity expansion; the global supply chain and our committed orders; customer demand and customers' ability to destock higher inventories accumulated during the COVID-19 pandemic; our expectation that most of the tariff-related costs will be absorbed by customers but we continue to take measures to monitor the evolving tariff situation; the success of our initiatives to optimize the industrial footprint, harmonize processes and enhance supply chain and logistics strategies; our geographical and industrial footprint; and our goals, strategies and investment plans. These statements are neither promises nor guarantees but involve known and unknown risks, uncertainties and other important factors and circumstances that may cause Stevanato Group's actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including conditions in the U.S. capital markets, negative global and domestic economic and political conditions, inflation, the impact of the conflict between Russia and Ukraine, the evolving events in Israel and Gaza, the Iran regional conflict (including U.S. participation), supply chain and logistical challenges and other negative developments in Stevanato Group’s business or unfavorable legislative or regulatory developments. The following are some of the factors that could cause our actual results to differ materially from those expressed in or underlying our forward-looking statements: (i) our product offerings are highly complex, and, if our products do not satisfy applicable quality criteria, specifications and performance standards, we could experience lost sales, delayed or reduced market acceptance of our products, increased costs and damage to our reputation; (ii) we must develop new products and enhance existing products, adapt to significant technological and innovative changes and respond to introductions of new products by competitors to remain competitive; (iii) if we fail to maintain and enhance our brand and reputation, our business, results of operations and prospects may be materially and adversely affected; (iv) we are highly dependent on our management and employees. Competition for our employees is intense, and we may not be able to attract and retain the highly skilled employees that we need to support our business and our intended future growth; (v) our business, financial condition and results of operations depend upon maintaining our relationships with suppliers and service providers; (vi) our business, financial condition and results of operations depend upon the availability and price of high-quality materials and energy supply and our ability to contain production costs; (vii) significant interruptions in our operations could harm our business, financial condition and results of operations; (viii) as a consequence of the COVID-19 pandemic, sales of vials to and for vaccination programs globally increased resulting in a revenue growth acceleration. The demand for such products may fluctuate, as the need for COVID-19 related solutions continue to decline;(ix) our manufacturing facilities are subject to operating hazards which may lead to production curtailments or shutdowns and have an adverse effect on our business, results of operations, financial condition or cash flows; (x) our business, financial condition and results of operations may be impacted by our ability to successfully expand capacity to meet customer demand; (xi) the loss of a significant number of customers or a reduction in orders from a significant number of customers, including through destocking initiatives or lack of transparency of our products held by customers, could reduce our sales and harm our financial performance; (xii) we may face significant competition in implementing our strategies for revenue growth in light of actions taken by our competitors; (xiii) our global operations are subject to international market risks that may have a material effect on our liquidity, financial condition, results of operations and cash flows; (xiv) we are required to comply with a wide variety of laws and regulations and are subject to regulation by various federal, state and foreign agencies; (xv) given the relevance of our activities in the healthcare sector, investments by non-Italian entities in the Company, as well as certain asset disposals by the Company, may be subject to the prior authorization of the Italian Government (so called "golden powers"); (xvi) if relations between China and the U.S. deteriorate (including in connection with the current trade policy of the U.S. government), our business in the U.S. and China could be materially and adversely affected; (xvii) the U.S. government recently imposed tariffs on certain products manufactured in several jurisdictions, including China, the United Kingdom and the European Union, and other jurisdictions. Such tariffs, including our ability or inability to recover tariffs and duties previously paid as well as other trade policies that the U.S. government may implement in the future and the restrictive trade measures that other countries may adopt in response thereto, could adversely affect our business by making it more difficult or costly to trade goods between different jurisdictions; (xviii) cyber security risks and the failure to maintain the confidentiality, integrity and availability of our computer hardware, software and internet applications and related tools and functions, could result in damage to our reputation, data integrity and/or subject us to costs, fines or lawsuits under data privacy or other laws or contractual requirements; (xix) our trade secrets may be misappropriated or disclosed, and confidentiality agreements with directors, employees and third parties may not adequately prevent disclosure of trade secrets and protect other proprietary information; (xx) if we are unable to obtain and maintain patent protection for our technology, products and potential products, or if the scope of the patent protection obtained is not sufficiently broad, we may not be able to compete effectively in our markets; (xxi) we depend in part on proprietary technology licensed from others, and if we lose our existing licenses or are unable to acquire or license additional proprietary rights from third parties, we may not be able to continue developing our potential products; and (xxii) we are obligated to maintain proper and effective internal controls over financial reporting. Our internal controls were not effective for the year ended December 31, 2025, and in the future may not be determined to be effective, which may adversely affect investor confidence in us and, as a result, the value of our ordinary shares. This list is not exhaustive. We caution you therefore against relying on these forward-looking statements, and we qualify all of our forward-looking statements by these cautionary statements.

These forward-looking statements speak only as at their dates. The Company undertakes no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible to predict all of these factors. Further, the Company cannot assess the impact of each such factor on our business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statements.

For a description of certain additional factors that could cause the Company’s future results to differ from those expressed in any such forward-looking statements, refer to the risk factors discussed under “Risk Factors” below and “Item 3D. Risk Factors” in our Annual Report on Form 20-F for the year ended December 31, 2025 filed with the U.S. Securities and Exchange Commission on March 4, 2026.

Stevanato Group S.p.A.

Notes to the Unaudited Interim Condensed Consolidated Financial Statements

(Unaudited)

Stevanato Group S.p.A. (herein referred to as the “Company” and together with its subsidiaries the “Group”) is headquartered in Italy and its registered office is located at via Molinella 17, Piombino Dese (Padova, Italy). The Group is active in the design, production and distribution of products and processes to provide integrated solutions for the bio-pharma and healthcare industries, leveraging on regular investment and the selected acquisition of skills and new technologies to maintain and enhance its status as a global leader in the bio-pharma industry. Principal products are containment solutions, drug delivery systems, medical devices, diagnostic and analytical services, visual inspection machines, assembling and packaging machines, and glass forming machines.

The Group has 12 manufacturing plants, including: (i) nine production plants for manufacturing and assembly of bio-pharma and healthcare products (in Italy, Germany, Slovakia, Brazil, Mexico, China, United States), and (ii) three plants for the production of machinery and equipment (in Italy and Denmark). In addition to the manufacturing plants, the Group has two sites for analytical services (in Italy and United States) and five commercial sites/ offices (in Italy, China, Japan, and India, which was incorporated on February 23, 2025). The Group continues to expand its global industrial footprint, primarily to support high-value solutions production in Italy and the United States. In Latina (Italy), commercial production began in 2023, with ongoing ramp‑up of high‑value syringe output. The Group is also preparing the next phase of ready-to-use cartridge manufacturing, currently expected to become commercially operational in 2027. In the United States, the Group is progressing with the development of its new EZ-fill® manufacturing hub in Fishers, Indiana. Customer validations -initiated in late 2023-, are expected to continue throughout 2026 and beyond. Commercial production began in the third quarter of 2024, and additional production lines will continue to be installed, validated and commercialized throughout 2026 and beyond. The facility is preparing for drug device contract manufacturing activities that are expected to become commercially available by the end of 2026. The global footprint allows the Group to sell products and provide services in approximately 65 countries worldwide.

Stevanato Group S.p.A. is controlled by Stevanato Holding S.r.l. which holds 73.73% of its share capital.

On July 16, 2021, Stevanato Group began trading on the New York Stock Exchange under the symbol "STVN".

These Unaudited Interim Condensed Consolidated Financial Statements of Stevanato Group S.p.A. were authorized for issuance on August 3, 2026 and have been prepared in accordance with IAS 34 - Interim Financial Reporting. These Unaudited Interim Condensed Consolidated Financial Statements should be read in conjunction with the Group’s consolidated financial statements at and for the year ended December 31, 2025 (the “Consolidated Financial Statements”), which have been prepared in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (“IFRS”). The accounting policies adopted are consistent with those used at December 31, 2025, except as described in Note 3 - Basis of preparation for the Unaudited Interim Condensed Consolidated Financial Statements “New standards, amendments and interpretations”.

The preparation of the Unaudited Interim Condensed Consolidated Financial Statements requires management to make estimates and assumptions that affect the reported amounts of revenue, expenses, assets and liabilities as well as disclosures of contingent liabilities. If in the future such estimates and assumptions, which are based on management’s best judgment at the date of these Unaudited Interim Condensed Consolidated Financial Statements, deviate from the actual circumstances, the original estimates and assumptions will be modified as appropriate in the period in which the circumstances change. Reference should be also made to the section “Use of estimates” in the Consolidated Financial Statements for a detailed description of the more significant valuation procedures used by the Group.

Revenue from contracts with customers include variable consideration. The Group estimates variable consideration using the expected value method and recognizes amounts to the extent that it is highly probable that a significant reversal of cumulative revenue would not occur. During the period, the Group revised its estimates based on updated information available at the reporting date, resulting in a corresponding update to the amount of expected customer variable consideration recognized in revenue.

Impairment tests of non-current assets (including goodwill and assets with an indefinite useful life for which impairment tests are performed for the preparation of the annual Consolidated Financial Statements) are not performed for the preparation of the Unaudited Interim Condensed Consolidated Financial Statements unless impairment indicators have been identified.

The actuarial valuations that are required for the determination of employee benefit provisions are also usually carried out during the preparation of the annual consolidated financial statements, except in the event of significant market fluctuations or significant plan amendments, curtailments or settlements. IAS 34 also requires the disclosure of the nature and amount of items affecting net income that are unusual due to their nature, size or significance.

It is also to be noted that income tax expense is recognized based on management’s estimate of the weighted average effective annual income tax rate expected for the full financial year.

These Unaudited Interim Condensed Consolidated Financial Statements include the interim condensed consolidated income statement, the interim condensed consolidated statement of comprehensive income, the interim condensed consolidated statement of financial position, the interim condensed consolidated statement of changes in equity, the interim condensed consolidated cash flow statement and the accompanying condensed notes. The Unaudited Interim Condensed Consolidated Financial Statements are presented in Euro, which is the functional and presentation currency of the Company, and amounts are stated in thousands of Euros, unless otherwise indicated.

The Group has prepared the financial statements on the basis that it will continue to operate as a going concern. The Company’s management considers that there are currently no material uncertainties that may cast significant doubts over this assumption. Management has formed a judgment that there is a reasonable expectation that the Group has adequate resources to continue in operational existence for the foreseeable future, and not less than one year after the date the unaudited interim condensed financial statements are approved to be issued.

As the Group is not including the full set of disclosures, as required in a complete set of financial statements, the interim financial statements of the Group are regarded as ‘condensed’, as per IAS 34.

During the period, the Group received refunds of certain U.S. import duties previously paid under measures imposed pursuant to the International Emergency Economic Powers Act (IEEPA). Refunds relating to inventories previously recognized in profit or loss were recorded as a reduction of cost of sales, while refunds relating to imported property, plant and equipment reduced the carrying amount of the related assets. As at June 30, 2026, the Group had not recognized any receivable in respect of potential additional refunds not yet received.

New standards, amendments and interpretations

The accounting policies adopted in the preparation of the Unaudited Interim Condensed Consolidated Financial Statements are consistent with those followed in the preparation of the Consolidated Financial Statements for the year ended December 31, 2025, except for the adoption of new standards and amendments effective from January 1, 2026. The Group has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

The following amendments and new standards effective from January 1, 2026 were adopted for the first time in 2026 and did not have a material impact on the Unaudited Interim Condensed Consolidated Financial Statements of the Group:

In May 2024, the IASB issued amendments to IFRS 9 — Financial Instruments and IFRS 7— Financial Instruments-Disclosure, with the aim to set financial liabilities using an electronic payment system and to assess contractual cash flow characteristics of financial assets, including those with environmental, social and governance (ESG)-linked features. They also amended disclosure requirements relating to investments in equity instruments designated at fair value through other comprehensive income and added disclosure requirements for financial instruments with contingent features that do not relate directly to basic lending risks and costs. These amendments became effective on or after January 1, 2026.

As part of the adoption of the amendments to IFRS 9 — Financial Instruments, the Group performed an assessment of its existing payment systems, including payment arrangements used across the Group’s legal entities, in order to evaluate their scope of

application under the new requirements and to assess the applicability of the available accounting policy elections. Based on the outcome of this assessment, the adoption of the new standard did not result in any impact on profit or loss or on equity at the date of first application. The identified effects relate to changes in the presentation and classification of certain transactions within the statement of cash flows and statement of financial position, including the restatement of the opening cash balance of the period, reflecting the revised guidance introduced by the new standard.

In July 2024, the IASB published 'Annual Improvements to IFRS Accounting Standards — Volume 11'. It contains amendments to five standards as a result of the IASB's annual improvements project (IFRS 1 — First-time Adoption of International Financial Reporting Standards, IFRS 7 — Financial Instruments: Disclosures, IFRS 9 — Financial Instruments, IFRS 10 — Consolidated Financial Statements, IAS 7 — Statement of Cash Flows). These amendments became effective on or after January 1, 2026.

The standards, amendments and interpretations issued by the IASB that will have mandatory application in 2027 or subsequent years are listed below:

In April 2024, the IASB issued the new standard IFRS 18 — Presentation and Disclosure in Financial Statements, with the aim to give investors more transparent and comparable information about companies' financial performance through the introduction of three sets of new requirements: improved comparability in the income statement; enhanced transparency of management-defined performance measures; more useful grouping of information in the financial statements. The new standard will affect all companies using IFRS Accounting Standards and will replace IAS 1 — Presentation of Financial Statements (while some of its requirements will be carried forward in IFRS 18). The standard is effective on or after January 1, 2027 but early adoption is possible. The Group is currently assessing the potential impact from the adoption of IFRS 18 on its consolidated financial statements.

Stevanato Group S.p.A. is the parent company of the Group and it holds, directly and indirectly, interests in the Group’s operating companies. The only change in the consolidation perimeter during the period relates to the deconsolidation of Balda C. Brewer Inc. following its sale to a third party on June 30, 2026, as further described in Note 13.

Subsidiaries

The Unaudited Interim Condensed Consolidated Financial Statements of the Group include the following companies controlled by the parent company Stevanato Group S.p.A. directly or indirectly through the subsidiaries Stevanato Group International a.s. and Balda Medical GmbH.:

Non-controlling interests

The equity and the net profit attributable to non-controlling interests at June 30, 2026 relate to Medical Glass a.s. in which the Group holds a 99.74% interest.

The Group is exposed to the following financial risks connected with its operations:

These risks could significantly affect the Group’s financial position, results of operations and cash flows. Therefore, the Group identifies and monitors these risks to identify potential negative effects in advance and takes action to mitigate them, primarily through its operating and financing activities and, if required, through the use of derivative financial instruments.

The Unaudited Interim Condensed Consolidated Financial Statements do not include all the information and notes on financial risk management required in the annual consolidated financial statements. For a detailed description of the financial risk factors and financial risk management of the Group, reference should be made to Note 38 of the Consolidated Financial Statements at and for the year ended December 31, 2025.

The principal foreign currency exchange rates used to translate other currencies into Euro were as follows:

The Group is not significantly impacted by seasonality. Although revenue and operating results have historically been stronger in the second half of the year, such fluctuations are a result of the timing of customer orders and deliveries rather than other demand patterns in the markets in which the Group operates.

Management identifies two operating segments, based on the internal organization and reporting structure of Stevanato Group. The criteria used to identify the Group’s operating segments are consistent with the way the chief operating decision-maker (identified as the Chief Executive Officer of Stevanato Group S.p.A.) assigns resources and monitors performance. They are:

The operating segments described above are also identified as reportable segments.
