INNOSPEC INC.

Innospec believes that honest and transparent business conduct is vital and is committed to ethical business practices and actively enforcing compliance with all applicable laws, regulations and rules. We have therefore adopted a Supplier Code of Conduct, pursuant to which our suppliers are required to comply with all applicable laws, rules and regulations, including those related to business integrity, human rights and safety, health and the environment. Innospec engages EcoVadis to conduct corporate social responsibility risk assessments of key suppliers and those operating out of high-risk locations. Among other things, EcoVadis assessments allow us to evaluate supplier policies and actions taken by the supplier and to identify further actions required to enforce compliance with internationally recognized human rights standards and fair labor practices. In 2021, Innospec extended the scope of its EcoVadis assessment program from raw material suppliers to also include non-raw material suppliers. Since December 2018, all new raw materials suppliers, regardless of location, are also required to undergo an EcoVadis assessment if the Company forecasts that its annual expenditures to such supplier will be above minimum value thresholds designated by the Company.

We also have an internal protocol to support our review of, and response to, concerns raised regarding our supply chain. Innospec may invoke sanctions against suppliers, up to and including termination of the business relationship, if they violate modern slavery laws.
