E.U., which are proposing a ban on the production of leaded fuel for the aviation industry earlier than the FAA timetable, unless an authorization under E.U. REACH is granted to the fuel producer.
Previous report
In 2021, the Organization for Economic Cooperation and Development (“OECD”) released Pillar Two Global Anti-Base Erosion model rules (“Pillar Two Rules”), designed to ensure large corporations are taxed at a minimum rate of 15% in all countries of operation. Although the U.S. has not enacted legislation implementing Pillar Two Rules, other countries where Innospec does business, including the U.K., have enacted legislation implementing Pillar Two Rules, which came into effect from January 1, 2024. We have evaluated the Pillar Two Rules and their impact on the current and future periods, and we have determined that the Pillar Two Rules do not have a material impact on the Company’s effective tax rate in the current period, and we do not expect the rules to have a material impact on the Company’s effective tax rate in future periods.
Previous report
Diverse chemical regulatory processes in different countries around the world might create complexity and additional cost. U.K. REACH, which was precipitated by the U.K.’s exit from the E.U., is one such example.

We are currently in the process of developing and implementing a new, company-wide, information system platform. The new platform provider is well established in the market. The implementation is a phased, risk-managed, site deployment following a multistage user acceptance program with the existing platforms providing a fallback position. We have implemented the new platform for a number of our sites across EMEA and ASPAC in the third quarter of 2024. In connection with this implementation, the Company has updated, and continues to update, its internal controls over financial reporting, as necessary, to accommodate modifications to its business processes and accounting procedures.

The U.S. Federal Aviation Administration (“FAA”) program (Piston Aviation Fuels Initiative) has been established to identify a replacement fuel, and candidate fuels are undergoing testing. In 2022, various general aviation industry groups in conjunction with the US EPA and FAA created a new team named Eliminate Aviation Gasoline Lead Emissions (“EAGLE”). This is a government-industry partnership that also encompasses fuel producers and distributors, airport operators, communities that support general aviation airports, and environmental experts. The most significant announcement impacting the Company is the stated aim of EAGLE to eliminate lead emissions from general aviation in the U.S. by the end of 2030 with Alaska having a derogation out to end 2032. Regulatory action in the EU on the prohibition of TEL use by EU based leaded avgas blenders under the EU REACH Regulations has resulted in three users successfully applying for EU REACH Authorization permitting continued TEL use until end of April 2032.
Previous wording
The outcome of new or potential legislation or regulation in the U.S. and other jurisdictions in which we operate may result in new or additional requirements, additional charges to fund energy efficiency activities, fees or restrictions on certain activities. Compliance with these initiatives may also result in additional costs to us, including, among other things, increased production costs, additional taxes, reduced emission allowances or additional restrictions on production or operations. Any climate change regulations enacted in the future could also negatively impact our ability to compete with companies situated in areas not subject to such limitations. Even without such regulation, increased public awareness and adverse publicity about potential impacts on climate change emanating from us or our industry could harm us. We may not be able to recover the cost of compliance with new or more stringent laws and regulations, which could adversely affect our business and negatively impact our growth. Furthermore, the potential impacts of climate change and related regulation on our customers are highly uncertain and may adversely affect us.
