The materiality assessment workflow at Othello has four stages: topic universe identification (drawn from GRI sector standards, IFRS S2, FTSE Russell themes, and peer benchmarking), stakeholder engagement (typically including investors, employees, suppliers, communities, regulators), impact and financial materiality scoring on a two-axis matrix, and validation with internal sustainability and finance leadership.

The deliverable is the bilingual materiality matrix ready for inclusion in the sustainability report and the 56-1 One Report ESG section. The matrix is supported by methodology disclosure (how impact and financial materiality were scored), stakeholder list (anonymized where confidentiality required), and the topic-prioritization narrative.

For listed companies under FTSE Russell methodology from 2026, the materiality matrix becomes a direct input to indicator weighting at the company level.

Best practice — and FTSE Russell expectation — is materiality refresh every two to three years, with annual reconfirmation. Full re-assessment is triggered by material business changes (M&A, new geographies, new product lines) or material regulatory changes (such as the 2026 SET-FTSE transition).
