RE100 Technical Criteria

Cigna's internal reporting criteria and definitions

Assurance standard

and level of assurance

We performed a limited assurance engagement, in accordance with the International Standard on Assurance Engagements ISAE 3000 (Revised) 'Assurance Engagements other than Audits or Reviews of Historical Financial Information'.

Independent Limited Assurance Report

ERM Certification & Verification Services Incorporated ("ERM CVS") was engaged by Cigna Corporate Services LLC ("Cigna") to provide limited assurance in relation to the Selected Information set out below and presented in the Cigna 2024 Corporate Impact Report (the "Report").

The procedures performed in a limited assurance engagement vary in nature and timing from and are less in extent than for a reasonable assurance engagement and consequently, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained had a reasonable assurance engagement been performed.

Respective responsibilities

Cigna is responsible for preparing the Report and for the collection and presentation of the information within it, and for the designing, implementing and maintaining of internal controls relevant to the preparation and presentation of the Selected Information.

ERM CVS' responsibility is to provide a conclusion to Cigna on the agreed assurance scope based on our engagement terms with Cigna, the assurance activities performed and exercising our professional judgement.

OUR CONCLUSION

Based on our activities, as described below, nothing has come to our attention to indicate that the Selected Information for 2024 is not fairly presented in the Report, in all material respects, in accordance with the reporting criteria.

OUR ASSURANCE ACTIVITIES

Considering the level of assurance and our assessment of the risk of material misstatement of the Selected Information a multi-disciplinary team of sustainability and assurance specialists performed a range of procedures that included, but was not restricted to, the following:

Evaluating the appropriateness of the reporting criteria for the Selected Information;

Interviewing management representatives responsible for managing the Selected Information;

Interviewing relevant staff to understand and evaluate the management systems and processes (including internal review and control processes) used for collecting and reporting the Selected Information;

Reviewing of a sample of qualitative and quantitative evidence supporting the Selected Information at a corporate level;

Performing an analytical review of the year-end data submitted by all locations included in the consolidated 2024 group data for the Selected Information which included testing the completeness and mathematical accuracy of conversions and calculations, and consolidation in line with the stated reporting boundary;

Evaluating the conversion factors, emission factors and assumptions used;

Reviewing the presentation of information relevant to the assurance scope in the Report to ensure consistency with our findings.

THE LIMITATIONS OF OUR ENGAGEMENT

The reliability of the Selected Information is subject to inherent uncertainties, given the available methods for determining, calculating or estimating the underlying information. It is important to understand our assurance conclusions in this context. Our work was undertaken at Cigna's head office. We did not undertake source data verification at any operated facilities.

OUR INDEPENDENCE, INTEGRITY AND QUALITY CONTROL
