Report of the statutory auditor

to the General Meeting of SIG Group AG, Neuhausen am Rheinfall

Report on the audit of the consolidated financial statements

Opinion

We have audited the consolidated financial statements of SIG Group AG and its subsidiaries (the Group), which comprise the consolidated statement of profit or loss and other comprehensive income for the year ended December 31, 2025, the consolidated statement of financial position as at December 31, 2025, the consolidated statement of changes in equity and the consolidated statement of cash flows for the year then ended, and notes to the consolidated financial statements, including material accounting policy information.

In our opinion, the consolidated financial statements (pages 223 to 289) give a true and fair view of the consolidated financial position of the Group as at December 31, 2025, and of its consolidated financial performance and its consolidated cash flows for the year then ended in accordance with IFRS Accounting Standards and comply with Swiss law.

Basis for opinion

We conducted our audit in accordance with Swiss law, International Standards on Auditing (ISA) and Swiss Standards on Auditing (SA-CH). Our responsibilities under those provisions and standards are further described in the ‘Auditor’s responsibilities for the audit of the consolidated financial statements’ section of our report. We are independent of the Group in accordance with the provisions of Swiss law and the requirements of the Swiss audit profession that are relevant to audits of the financial statements of public interest entities, as well as the International Code of Ethics for Professional Accountants (including International Independence Standards) issued by the International Ethics Standards Board for Accountants (IESBA Code), as applicable to audits of financial statements of public interest entities. We have also fulfilled our other ethical responsibilities in accordance with these requirements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Our audit approach

Overview

Overall group materiality: €32 million

The entities addressed by our full scope audit work as well as specified procedures contribute to 83% of the Group’s revenues

As key audit matters the following areas of focus have been identified:

Recoverability of goodwill
Impairment of intangible and other long-lived assets

Materiality

The scope of our audit was influenced by our application of materiality. Our audit opinion aims to provide reasonable assurance that the consolidated financial statements are free from material misstatement. Misstatements may arise due to fraud or error. They are considered material if, individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the consolidated financial statements.

Based on our professional judgement, we determined certain quantitative thresholds for materiality, including the overall Group materiality for the consolidated financial statements as a whole as set out in the table below. These, together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures and to evaluate the effect of misstatements, both individually and in aggregate, on the consolidated financial statements as a whole.

Auditor’s report – materiality
Overall Group materiality		€32 million
Benchmark applied		Revenue
Rationale for the materiality benchmark applied		We chose revenue as the benchmark as, in our view, it is the most appropriate measure considering the Group’s current year’s result is impacted by effects from purchase price accounting. It is further a generally accepted benchmark.

We agreed with the Audit and Risk Committee that we would report to them misstatements above €3 million identified during our audit as well as any misstatements below that amount which, in our view, warranted reporting for qualitative reasons.

Audit scope

We designed our audit by determining materiality and assessing the risks of material misstatement in the consolidated financial statements. In particular, we considered where subjective judgements were made; for example, in respect of significant accounting estimates that involved making assumptions and considering future events that are inherently uncertain. As in all of our audits, we also addressed the risk of management override of internal controls, including among other matters consideration of whether there was evidence of bias that represented a risk of material misstatement due to fraud.

We tailored the scope of our audit in order to perform sufficient work to enable us to provide an opinion on the consolidated financial statements as a whole, taking into account the structure of the Group, the accounting processes and controls, and the industry in which the Group operates.

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the consolidated financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Recoverability of goodwill

Auditor’s report – key audit matters – goodwill
Key audit matter		How our audit addressed the key audit matter
As at December 31, 2025, the carrying amount of goodwill was €3,034.8 million, allocated to different groups of cash generating units (CGUs), which for impairment testing purpose are the four operating (and reportable) segments. The recoverable amounts of the respective group of CGUs are calculated based on their value in use. Deriving the value in use requires significant management judgement specifically in determining future cash flows, discount rates and terminal growth rates. Management also used third-party valuation support. We consider the recoverability of goodwill to be a key audit matter, as management applies significant judgement in this area. Refer to the consolidated financial statements Note 14 – Intangible assets and Note 5.4 – Significant accounting judgements, estimates and assumptions as well as Note 5.5.3 Impairment of non-financial assets.		We assessed whether the CGUs identified by Management are appropriate. We further assessed whether the allocation of goodwill to the respective group of CGUs is the appropriate basis for impairment testing. With the involvement of our internal valuation experts, we assessed the methodology used to perform the impairment test in accordance with the provisions of IAS 36 and evaluated and challenged Management’s value in use calculation for each group of CGUs. This included an assessment of the appropriateness of the model used, as well as challenging the key assumptions made by Management.
		With the involvement of our internal valuation experts, we evaluated the reasonableness of the discount rates and terminal growth rates, as determined by Management. We ensured consistency of Management’s cash flow assumptions by comparing them to the Group’s 5-year business plan as approved by the Board of Directors. We challenged Management’s cash flow assumptions and sensitivity analyses. We evaluated the planning accuracy of Management’s forecast model by comparing historical forecasts to actual results. We verified the mathematical accuracy of the model and recalculated the headroom for each group of CGUs.
		We further performed independent sensitivity analyses around the key assumptions to ascertain the extent of changes in those assumptions that either individually or collectively would be required for the goodwill to be impaired and verified proper disclosure of these sensitivities in the notes. We also considered the market capitalisation of the Group in comparison with the Group’s equity value.

Impairment of intangible and other long-lived assets

Auditor’s report – key audit matters – Impairment of intangible and other long-lived assets
Key audit matter		How our audit addressed the key audit matter
As announced on September 18, 2025, following a strategic review of the business and in light of the prevailing soft market conditions, the Group has recognized impairment losses and other charges of €350.7 million pre-tax. The total charges include an impairment of € 95 million to the value of the bag-in-box and spouted pouch business reflecting weak consumer sentiment and business performance, an impairment of €85.7 million to the value of the chilled carton business principally reflecting weak market conditions in China. Another €37.6 million impairment related to the Indian aseptic carton business. The recoverable amounts of the related businesses and operating capacities are calculated based on the higher of their value in use and fair value less costs of disposal. Deriving the value in use or fair value less costs of disposal requires significant management judgement specifically in determining future cash flows, discount rates and terminal growth rates. Management also used third-party valuation support. We consider the impairment of intangible and other long-lived assets to be a key audit matter, as management applies significant judgement in this area. Refer to the consolidated financial statements Note 4 – Key events and transactions, Note 12 – Property, plant and equipment, Note 13 – Right-of-use assets, Note 14 – Intangible assets and Note 5.4 – Significant accounting judgements, estimates and assumptions.		We assessed whether the businesses identified by Management are the appropriate basis for impairment testing. With the involvement of our internal valuation experts, we assessed the methodology used to perform the impairment test in accordance with the provisions of IAS 36 and evaluated and challenged Management’s value in use calculation for each business, identified as a cash generating unit. This included an assessment of the appropriateness of the model used, as well as challenging the key assumptions made by Management.
		With the involvement of our internal valuation experts, we evaluated the reasonableness of the discount rates and terminal growth rates, as determined by Management, by assessing the cost of capital for the business, as well as by considering regional specific factors We challenged Management’s cash flow assumptions. We evaluated the planning accuracy of Management’s forecast model by comparing historical forecasts to actual results. We verified the mathematical accuracy of the model.
		We also involved our internal valuation experts to evaluate Management’s fair value less costs of disposal calculation for individual assets. We verified whether the allocation of the impairment charges to intangible assets, property, plant and equipment and right-of-use assets categories have been in accordance with IAS 36, and we also verified that the disclosures in the consolidated financial statements are in accordance with IFRS Accounting Standards.

Other information

The Board of Directors is responsible for the other information. The other information comprises the information included in the annual report, but does not include the financial statements, the consolidated financial statements, the compensation report and our auditor’s reports thereon.

Our opinion on the consolidated financial statements does not cover the other information and we do not express any form of assurance conclusion thereon.

In connection with our audit of the consolidated financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the consolidated financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated.

If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.

Board of Directors’ responsibilities for the consolidated financial statements

The Board of Directors is responsible for the preparation of consolidated financial statements, that give a true and fair view in accordance with IFRS Accounting Standards and the provisions of Swiss law, and for such internal control as the Board of Directors determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, the Board of Directors is responsible for assessing the Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Board of Directors either intends to liquidate the Group or to cease operations, or has no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Swiss law, ISA and SA-CH will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

A further description of our responsibilities for the audit of the consolidated financial statements is located on EXPERTsuisse’s website: http://www.expertsuisse.ch/en/audit-report. This description forms an integral part of our report.

Report on other legal and regulatory requirements

In accordance with article 728a para. 1 item 3 CO and PS-CH 890, we confirm the existence of an internal control system that has been designed, pursuant to the instructions of the Board of Directors, for the preparation of the consolidated financial statements.

We recommend that the consolidated financial statements submitted to you be approved.
