CAUTIONARY STATEMENT RELATIVE TO FORWARD-LOOKING STATEMENTS

FORWARD-LOOKING STATEMENTS

This Form 10-K contains certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts included or incorporated herein may constitute forward-looking statements. Such forward-looking statements include statements (covered by words like “expects,” “estimates,” “anticipates,” “may,” “could,” “believes,” “feels,” “plans,” “intends” or similar words or expressions, for example) which relate to earnings, growth potential, operating performance, events or developments that we expect or anticipate will or may occur in the future. Although forward-looking statements are believed by management to be reasonable when made, they are subject to certain risks, uncertainties and assumptions, and our actual performance or results may differ materially from these forward-looking statements. You are urged to review our discussion of risks and uncertainties that could cause actual results to differ from forward-looking statements under the heading “Risk Factors.” Innospec undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

PART I

Item 1 Business

When we use the terms “Innospec,” “the Corporation,” “the Company,” “Registrant,” “we,” “us” and “our,” we are referring to Innospec Inc. and its consolidated subsidiaries unless otherwise indicated or the context otherwise requires.

General

Innospec develops, manufactures, blends, markets and supplies a wide range of specialty chemicals to markets in the Americas, Europe, the Middle East, Africa and Asia-Pacific. Our Performance Chemicals business creates innovative technology-based solutions for our customers in the personal care, home care, agrochemical, mining and industrial markets. Our Fuel Specialties business specializes in manufacturing and supplying fuel additives that improve fuel efficiency, boost engine performance and reduce harmful emissions. Our Oilfield Services business supplies drilling, completion and production chemicals which make exploration and production more effective, cost-efficient and environmentally friendly.

Segment Information

The Company reports its financial performance based on three reportable segments which are Performance Chemicals, Fuel Specialties and Oilfield Services.

Our Octane Additives segment has previously ceased trading and is no longer a reporting segment from July 1, 2020, as reported in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2020.

For financial information about each of our segments, see Note 3 of the Notes to the Consolidated Financial Statements.

Performance Chemicals

Our Performance Chemicals segment provides innovative technology-based solutions for our customers’ processes or products focused in the personal care, home care, agrochemical, mining and other industrial markets.

This segment has grown through acquisitions, together with the organic development and marketing of innovative products in these end-markets.

Our customers in this segment include large multinational companies, manufacturers of personal care and home care products and global mining, agriculture and building products and other industrial companies.

Fuel Specialties

Our Fuel Specialties segment develops, manufactures, blends, markets and supplies a range of specialty chemical products used as additives in diesel, jet, marine, fuel oil and other fuels.

2

These fuel additive products help improve fuel efficiency, boost engine performance and reduce harmful emissions; and are most commonly used in the efficient operation of commercial trucking, marine and aviation engines, power station generators, heating oil and other industrial machinery applications.

The segment has grown organically through our development of new products to address increased demand for fuel, focus on fuel economy, higher efficiency engine technologies and legislative developments, including tightening global emissions regulations. We are also applying these fuels technologies to an increasing number of non-fuel applications in a variety of industries.

Our customers in this segment include national and multinational oil companies, fuel marketers and retailers, fuel terminals, marine lines, coating & plastics producers and other heavy industrial end-users.

Oilfield Services

Our Oilfield Services segment develops and markets chemical solutions for fracturing, drilling, stimulation and completion operations, products for oil and gas production and transport which aid flow assurance and maintain asset integrity.

Our customers in this segment include multinational public and independent exploration & production and oilfield services companies currently operating principally in the Americas.

Strategy

Our strategy is to develop new and improved products and technologies to continue to strengthen and increase our market positions within our Performance Chemicals, Fuel Specialties and Oilfield Services segments. We also actively continue to assess potential strategic acquisitions, partnerships and other opportunities that would enhance and expand our customer offering. We focus on opportunities that would extend our technology base, geographical coverage or product portfolio. We believe that focusing on the Performance Chemicals, Fuel Specialties and Oilfield Services segments, in which the Company has existing experience, expertise and knowledge, provides opportunities for positive returns on investment with reduced operating risk. We also continue to expand our geographical footprint, consistent with the development of global markets.

Geographical Area Information

Financial information with respect to our domestic and foreign operations is contained in Note 3 of the Notes to the Consolidated Financial Statements.

Working Capital

The nature of our customers’ businesses generally requires us to hold appropriate amounts of inventory in order to respond quickly to customers’ needs. We therefore require corresponding amounts of working capital for normal operations. We do not believe that this is materially different to our competitors.

3

The purchase of large amounts of certain raw materials across all our segments can create some variations in working capital requirements, but these are planned and managed by the business.

We do not believe that our terms of sale or purchase differ markedly from those of our competitors.

Raw Materials and Product Supply

We use a variety of raw materials and chemicals in our manufacturing and blending processes and believe that sources for these are adequate for our current operations. Our major purchases are oleochemicals and derivatives, cetane number improvers, ethylene, various solvents, amines, alcohols, olefin and polyacrylamides. These purchases account for a substantial portion of the Company’s variable manufacturing costs. These materials are, with the exception of ethylene for our operations in Germany, available from more than one source. Although ethylene is, in theory, available from several sources, it is not permissible to transport ethylene by road in Germany. As a result, we source ethylene for our German operations via a direct pipeline, making it effectively a single source. Ethylene is used as a primary raw material for one of our German operations in products representing approximately 5% of Innospec’s sales.

We use long-term contracts (generally with fixed or formula-based costs) and advance bulk purchases to help ensure availability and continuity of supply, and to manage the risk of cost increases. From time to time, for some raw materials, the risk of cost increases is managed with commodity swaps.

We continue to monitor the situation and adjust our procurement strategies as we deem appropriate. The Company forecasts its raw material requirements substantially in advance, and seeks to build long-term relationships and contractual positions with supply partners to safeguard its raw material positions. In addition, the Company operates an extensive risk management program which seeks to source key raw materials from multiple sources and to develop suitable contingency plans.

Intellectual Property

Our intellectual property, including trademarks, patents and licenses, forms a significant part of the Company’s competitive advantage for all our segments. The Company does not, however, consider its business as a whole to be dependent on any one trademark, patent or license.

The Company has a portfolio of trademarks and patents, both granted and in the application stage, covering products and processes in several jurisdictions. The majority of these patents were developed by the Company and, subject to maintenance obligations including the payment of renewal fees, have at least 10 years life remaining.

The trademark “Innospec and the Innospec device” in Classes 1, 2 and 4 of the “International Classification of Goods and Services for the Purposes of the Registration of Marks” are

4

registered in all jurisdictions in which the Company has a significant market presence. The Company also has trademark registrations for certain product names in all jurisdictions in which it has a significant market presence.

We actively protect our inventions, new technologies, and product developments by filing patent applications and maintaining trade secrets. In addition, we vigorously participate in patent opposition proceedings around the world where necessary to secure a technology base free from infringement of intellectual property.

Customers

In 2022, the Company had a significant customer in the Oilfield Services segment which accounted for $222.2 million (11.3%) of our net group sales.

Competition

Certain markets in which the Company operates are subject to significant competition. The Company competes on the basis of a number of factors including, but not limited to, product quality and performance, specialized product lines, customer relationships and service, and regulatory expertise.

Performance Chemicals: Within the Performance Chemicals segment we operate in the personal care, home care, agrochemical, mining markets and other industrial markets, which are highly fragmented, and the Company experiences substantial competition from a large number of multinational and specialty chemical suppliers in each geographical market. Our competitive position in these markets is based on us supplying a superior, diverse product portfolio which solves particular customer problems or enhances the performance of new or existing products. In a number of specialty chemicals markets, we also supply niche product lines, where we enjoy market-leading positions.

Fuel Specialties: The Fuel Specialties segment is generally characterized by a small number of competitors, none of which hold a dominant position. We consider our competitive edge to be our proven technical development capacity, independence from major oil companies and strong long-term customer relationships. We believe we remain the world’s only producer of tetra ethyl lead (“TEL”) for use in aviation gasoline, which we market as our AvGas product line.

Oilfield Services: Our Oilfield Services segment is very fragmented and although there are a small number of very large competitors, there are also a large number of smaller players focused on specific technologies or regions. Our competitive strength is our proven technology, broad regional coverage and strong customer relationships.

Research, Development, Testing and Technical Support

Research, product/application development and technical support (“R&D”) provide the basis for the growth of our Performance Chemicals, Fuel Specialties and Oilfield Services

5

segments. Accordingly, the Company’s R&D activity has been, and will continue to be, focused on the development of new products and formulations. Our R&D department provides technical support for all of our reporting segments. Expenditures to support R&D services were $38.7 million, $37.4 million and $30.9 million in 2022, 2021 and 2020, respectively.

We believe that our proven technical capabilities provide us with a significant competitive advantage. Our Performance Chemicals business has launched significant new mild surfactants, which are well aligned with developing customer needs. In addition, the business has developed further formulations in emollients, silicones and surfactants for the personal care, home care, agrochemical, mining markets and other industrial markets. Fuel Specialties has continued to innovate, focused on bringing new technologies to market which reduce pollution and improve fuel economy, including detergents and cold flow improvers. In Oilfield Services, new technologies have been introduced to improve the hydrocarbon yield from customers’ operations and to protect assets, including friction modifiers, biocide formulations and additives to improve drilling muds.

Health, Safety and Environmental Matters

We are subject to environmental laws in the countries in which we operate and conduct business. Management believes that the Company is in material compliance with applicable environmental laws and has made the necessary provisions for the continued costs of compliance with environmental laws.

Our principal site giving rise to asset retirement obligations is our Ellesmere Port manufacturing site in the United Kingdom. There are also asset retirement obligations and environmental remediation liabilities on a much smaller scale in respect of other manufacturing sites. We regularly review the future expected costs of remediation and the current estimate is reflected in the Consolidated Balance Sheets and Note 13 of the Notes to the Consolidated Financial Statements.

The European Union (“E.U.”) legislation known as the Registration, Evaluation and Authorization of Chemical Substances Regulations (“REACH”) requires most of the substances in the Company’s products to be registered with the European Chemicals Agency. Under this legislation the Company has to demonstrate that the substances it uses in its products are safe for use and appropriate for their intended purposes in the E.U.. During this registration and continual evaluation process, the Company incurs expenses to test and register substances it manufactures or imports in the E.U..

Following the end of the Brexit transition process, on January 11, 2021 the United Kingdom (“U.K.”) government introduced U.K. REACH with the same registration requirements for substances produced in or imported into the U.K.. Furthermore, globally, similar regulatory regimes to the E.U. and U.K. REACH are also entering into force or are being proposed in several other countries. These registration based regulatory regimes will result in increasing test expenses and registration fees to ensure Innospec products remain compliant with the appropriate regulations and can continue to be sold in these markets.

Environmental, Social & Governance (“ESG”) and Corporate Social Responsibility Reporting

As part of our commitment to being open and transparent about our performance, our latest Responsible Business Report, which is our 2021 Report, was independently assured to assess its adherence to the globally recognized AA1000 Assurance Standard.

The Responsible Business Report, along with further information on our sustainability program and performance is available online in the “Corporate Social Responsibility” section of the Company’s website at https://innospecsustainability.com. Such information does not constitute part of, and is not incorporated by reference into this Annual Report on Form 10-K.

Employees and Human Capital Management

The Company had approximately 2,100 employees in 25 countries as at December 31, 2022.

Human capital management is critical to Innospec’s ongoing business success, which requires investing in our people. Our aim is to create a highly engaged and motivated workforce where employees are inspired by leadership, engaged in purpose-driven, meaningful work and have opportunities for growth and development.

An effective approach to human capital management requires that we invest in talent, development, culture and employee engagement. We aim to create an environment where our employees are encouraged to make positive contributions and fulfill their potential.

The Company’s Board of Directors (the “Board”) is also actively involved in reviewing and approving executive compensation, selections and succession plans so that we have leadership in place with the requisite skills and experience to deliver results the right way. The Company’s Chief Executive Officer (“CEO”) periodically provides the Board with an assessment of senior executives that have potential as successor for the CEO position, as well as perspectives on potential candidates for other senior management positions.

Core Values & Culture

Responsible Growth through Innovation and Customer Service: Financial stability and growth are essential to maintain our goal of making a positive contribution towards a more sustainable future. Generating economic benefits for our employees, stockholders, and local communities, while encouraging ongoing innovation in our product portfolio alongside excellent customer service which will allow our business to be competitive and sustainable.

Caring for People: We strive to create a safe and caring culture where our employees are supported and encouraged to make positive contributions. Our continued success depends on keeping people safe, promoting a healthy lifestyle, protecting human rights, improving education, training and maintaining good relations with our neighbors.

Conserving & Protecting the Environment: We aim to use resources as efficiently as practicable and minimize the impact of our operations on the environment. We look to supply

7

safe, sustainable products, designed to meet the needs of society now and in the future while minimizing their environmental impact.

Leading by Example: We understand that honest, ethical and transparent conduct is vital to our success and reputation. Every employee plays an essential part in complying with local and national laws, rules and regulations. We uphold a high standard of corporate and business integrity across all of our activities.

Employee Engagement

Attracting Talent: We believe our hardworking team of employees is our greatest asset. We employ approximately 2,100 people across 25 countries and we believe that the skills, commitment and enthusiasm of our employees helps us to deliver long-term growth for investors.

Training: Across our sites, we provide local support and opportunities for the next generation of talent in our industry by offering a range of placements, internships, work experience and apprenticeships. We strive to attract and retain the best talent in a changing and competitive working environment.

As an organization, we are committed to making Innospec a great company to work for and we invest, as appropriate, in the development of our employees to meet this ambition.

Our employees are offered both internal and external training, where appropriate, to support their continued development and to meet the needs of our business. Where relevant, we support our employees’ ongoing professional training and development to encourage their progression within our business.

Pay and Benefits: We offer what we believe are competitive reward and recognition programs, based on both business-wide and individual performance. Our packages have been designed to attract and retain the best employees, reward achievement and encourage our teams to deliver superior performance for our customers and our company.

In addition to our company-wide performance incentive plans, we encourage our employees to share in the long-term success of our company with incentive programs, such as our Global Sharesave Plan. This plan gives employees the opportunity to participate in a savings plan linked to an option to buy shares in Innospec at a discount and, therefore, benefit from any growth in the share price over the savings period. We also provide a range of other benefits in line with the market practice in each location we operate in, including insurance and pension arrangements.

Performance Management Framework: We conduct an annual performance management process across the organization. Together with their line managers, employees agree upon annual objectives, and, at the end of the year, review with their line manager their performance against those objectives and their overall performance. The results of each annual performance review affect performance bonus amounts, pay reviews and career advancement decisions.

8

Senior Leadership Communications and Transparency: We actively seek opportunities for regular engagement and communication by our CEO and other senior executives with our broader employee population. Communications are through a variety of means including written communications, webcasts and conference calls. For example, we hold a CEO Call at least once a year, during which the CEO and CFO discuss current issues and developments in the business, including a Q&A session answering questions raised by employees. The CEO Call is accessible to all employees across the Company. In addition to the CEO Calls, each financial quarter, following the quarterly financial results announcement, the CEO and CFO provide a written review of the financial results to all employees.

Diversity and Inclusion

Innospec aims to attract and retain the best people by ensuring that employment decisions are based on merit, performance, ability and contribution to the Company. As part of our Global HR Policy, our diversity and equal opportunities policy ensures that current and prospective employees receive equal opportunities irrespective of gender, sexual orientation, race, color, ethnic or national origin, marital status, age, disability, religion or belief.

Health and Safety

Objectives: We prioritize the safety of employees, communities and everyone involved in the manufacture, use or disposal of our products. We set high standards for process and occupational safety, which is managed by our network of Safety, Health and Environment (“SHE”) professionals throughout the business. Our three core objectives being that:

• No-one gets hurt

• We don’t annoy our neighbors

• We leave only the gentlest footprints on our environment

Leadership: The Company periodically reviews the Corporate SHE structure and organization so that we have the optimum resources and correct approach. We strive to embed SHE in our culture by having leadership that comes from executive management. Our Responsible Care Executive Committee (known as RESPECT) comprises members of the senior leadership team and is led by the CEO. RESPECT is responsible for setting the group’s SHE and Sustainability policies and objectives across the global business. It also monitors ongoing performance in these areas throughout the year. Through this structure, we have established a strong culture of safety within our organization.

Training: Training is an essential part of our health and safety strategy. To minimize the risk of accident or injury, we give our employees the information they need, delivered effectively and at the appropriate time. Our ongoing training programs demonstrate our commitment to targeting zero accidents, making sure that safety is always front of mind and that we continually raise standards.

Every year, employees across our sites take part in a variety of site-specific training courses to enable them to be competent and safe in their roles.

Item 1A    Risk Factors

The factors described below represent the principal risks associated with our business.

Global Conditions

Competition and market conditions may adversely affect our operating results.

In certain markets, our competitors are larger than us and may have greater access to financial, technological and other resources. As a result, competitors may be better able to adapt to changes in conditions in our industries, fluctuations in the costs of raw materials or changes in global economic conditions. Competitors may also be able to introduce new products with enhanced features that may cause a decline in the demand and sales of our products. Consolidation of customers or competitors, or economic problems of customers in our markets could cause a loss of market share for our products, place downward pressure on prices, result in payment delays or non-payment, or declining plant utilization rates. These risks could adversely impact our results of operations, financial position and cash flows.

Russian military invasion of the sovereign state of Ukraine.

On February 24, 2022, Russia launched an invasion into Ukraine which has had some effect on our ability to obtain and import certain raw materials used to manufacture our products and our ability to export and sell our products in these countries. The ongoing conflict, and sanctions imposed upon Russia and Belarus, may impact on the Company’s sales, cost of procuring raw materials or distribution costs in future periods. The wider implications of the conflict have driven up the cost of energy and utilities used to operate our manufacturing plants, particularly in Europe, with the further potential for issues relating to the supply of energy, particularly natural gas, for our manufacturing sites in countries reliant on supplies from Russia. The fluidity and continuation of the conflict may result in additional economic sanctions and other impacts which could have a negative impact on the Company’s financial condition, results of operations and cash flows. These include decreased sales; supply chain and logistics disruptions; volatility in foreign exchange rates and interest rates; inflationary pressures on raw materials and energy; and heightened cybersecurity threats.

Continuing adverse global economic conditions could materially affect our current and future businesses.

Global economic factors affecting our business include, but are not limited to, geopolitical instability in some markets, consumer demand for premium personal care and cosmetic products, miles driven by passenger and commercial vehicles, legislation to control fuel quality, impact of alternative propulsion systems, and oil and gas drilling and production rates. The availability, cost and terms of credit have been, and may continue to be, adversely affected by the foregoing factors and these circumstances have produced, and may in the future result in, illiquid markets and wider credit spreads, which may make it difficult or more expensive for us to obtain credit.

11

The level of inflation and energy costs, particularly in Europe, may result in an adverse impact to the Group’s results from employee wages and other costs of operations of our manufacturing sites.

Continuing uncertainties in the U.S. and international markets and economies leading to a decline in business and consumer spending could adversely impact our results of operations, financial position and cash flows.

Domestic or international natural disasters or terrorist attacks may disrupt our operations, decrease the demand for our products or otherwise have an adverse impact on our business.

Chemical related assets, and U.S. corporations such as us, may be at greater risk of future terrorist attacks than other possible targets in the U.S., the U.K. and throughout the world. Extraordinary events such as natural disasters may negatively affect local economies, including those of our customers or suppliers. The occurrence and consequences of such events cannot be predicted, but they can adversely impact economic conditions in general and in our specific markets. The resulting damage from such events could include loss of life, severe injury and property damage or site closure. Any of these matters could adversely impact our results of operations, financial position and cash flows.

While Innospec maintains business continuity plans that are intended to allow it to continue operations or mitigate the effects of events that could disrupt its business, Innospec cannot provide assurances that its plans would fully protect it from all such events. In addition, insurance maintained by Innospec to protect against property damage, loss of business and other related consequences resulting from catastrophic events is subject to coverage limitations, depending on the nature of the risk insured. This insurance may not be sufficient to cover all of Innospec’s damages or damages to others in the event of a catastrophe. In addition, insurance related to these types of risks may not be available now or, if available, may not be available in the future at commercially reasonable rates.

Our business and operations have been, and may in the future, be adversely affected by epidemics, pandemics, outbreaks of disease and other adverse public health developments, including COVID-19.

Epidemics, pandemics, outbreaks of novel diseases and other adverse public health developments in countries and states where we operate may arise at any time. Such developments, including the COVID-19 pandemic, have had, and in the future may have, an adverse effect on our business, financial condition and results of operations. These effects include a potentially negative impact on the availability of our key personnel, labor shortages and increased turnover, temporary closures of our facilities or facilities of our business partners, customers, suppliers, third-party service providers or other vendors, and interruption of domestic and global supply chains, distribution channels and liquidity and capital or financial markets. In particular, restrictions on or disruptions of transportation, port closures or increased border controls or closures, or other impacts on domestic and global supply chains or distribution channels, could increase our costs for raw materials and commodity costs,

12

increase demand for raw materials and commodities from competing purchasers, limit our ability to meet customer demand or otherwise have a material adverse effect on our business, financial condition and results of operations or cash flows.

Precautionary measures that we may take in the future intended to limit the impact of any epidemic, pandemic, disease outbreak or other public health development, may result in additional costs. In addition, such epidemics, pandemics, disease outbreaks or other public health developments may adversely affect economies and financial markets throughout the world, such as the effect that COVID-19 has had on world economies and financial markets, which may affect our ability to obtain additional financing for our businesses and demand for our products and services. The extent to which COVID-19 or other pandemics will impact our business and our financial results in the future will depend on future developments, which are highly uncertain and cannot be predicted. Such developments may include ongoing spread of the virus, disease severity, outbreak duration, extent of any reoccurrence of the coronavirus or any evolutions or mutations of the virus, and availability, administration and effectiveness of vaccines and development of therapeutic treatments that can restore consumer and business economic confidence.

Business Operations

We face risks related to our foreign operations that may adversely affect our business.

We serve global markets and operate in certain countries with political and economic instability, including the Middle East, Northern Africa, Asia-Pacific, Eastern Europe and South American regions. Our international operations are subject to numerous international business risks including, but not limited to, geopolitical and economic conditions, military actions and war, risk of expropriation, import and export restrictions, trade wars, exchange controls, national and regional labor strikes, high or unexpected taxes, government royalties and restrictions on repatriation of earnings or proceeds from liquidated assets of overseas subsidiaries. Any of these could have a material adverse impact on our results of operations, financial position and cash flows.

We may not be able to consummate, finance or successfully integrate future acquisitions, partnerships or other opportunities into our business, which could hinder our strategy or result in unanticipated expenses and losses.

Part of our strategy is to pursue strategic acquisitions, partnerships and other opportunities to complement and expand our existing business. The success of these transactions depends on our ability to efficiently complete transactions, integrate assets and personnel acquired in these transactions and apply our internal control processes to these acquired businesses. Consummating acquisitions, partnerships or other opportunities and integrating acquisitions involves considerable expense, resources and management time commitments, and our failure to manage these as intended could result in unanticipated expenses and losses. Post-acquisition integration may result in unforeseen difficulties and may deplete significant financial and management resources that could otherwise be available for the ongoing

13

development or expansion of existing operations. Furthermore, we may not realize the benefits of an acquisition in the way we anticipated when we first entered the transaction. Any of these risks could adversely impact our results of operations, financial position and cash flows.

Our success depends on our management team and other key personnel, the loss of any of whom could disrupt our business operations.

Our future success will depend in substantial part on the continued services of our senior management. The loss of the services of one or more of our key executive personnel could affect the implementation of our business plan and result in reduced profitability. Our future success also depends on the continued ability to attract, develop, retain and motivate highly-qualified technical and support staff. We cannot guarantee that we will be able to retain our key personnel or attract or retain qualified personnel in the future. If we are unsuccessful in our efforts in this regard, this could adversely impact our results of operations, financial position and cash flows.

An information technology system failure may adversely affect our business.

We rely on information technology systems to transact our business. Like other global companies, we and our third party service providers have, from time to time, been and will likely in the future be, subject to or targets of unauthorized or fraudulent access, including, but not limited to, physical or electronic break-ins or unauthorized tampering, as well as attempted cyber and other security threats and other computer-related penetrations including by state actors, terrorists or organized crime. Also, like other global companies, we have an increasing challenge of attracting and retaining highly qualified security personnel to assist us in combatting these security threats. The frequency and sophistication of such threats continue to increase, with malicious actors frequently changing tactics and techniques. These threats often become further heightened in connection with geopolitical tensions. Although we have implemented administrative and technical controls and take protective actions to reduce the risk of cyber incidents and breaches of our information technology, and we endeavor to modify such procedures as circumstances warrant, such measures may be insufficient to prevent physical and electronic break-ins, cyber-attacks or other security breaches to our computer systems.

Our systems, processes, software and network and those of our third party service providers may be vulnerable to internal or external security breaches, computer viruses, malware or other malicious code or cyber-attacks, catastrophic events, power interruptions, hardware failures, fire, natural disasters, human error, system failures and disruptions, and other events that could have security consequences. An information technology failure or disruption could prevent us from being able to process transactions with our customers, operate our manufacturing facilities, and properly report those transactions in a timely manner. Our information technology costs may increase to ensure the appropriate level of cyber security as we continuously adapt to the changing technological environment.

While we have limited insurance coverage in place that may, subject to policy terms and conditions, cover certain aspects of cyber risks, this insurance coverage is subject to certain

14

limitations and may not be applicable to a particular incident or otherwise be sufficient to cover all our losses beyond any coverage limitations. Furthermore, a significant or protracted information technology system failure may result in a material adverse effect on our results of operations, financial position and cash flows.

Decline in our AvGas business

The sales of our AvGas product line for use in aviation fuel are recorded within our Fuel Specialties business. The piston aviation industry has been, and is currently, researching a safe replacement fuel to replace leaded fuel. The U.S. Federal Aviation Administration (“FAA”) program (Piston Aviation Fuels Initiative) has been established to identify a replacement fuel, and candidate fuels are at an early pre-screening stage. In 2022, the 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 by the end of 2030. There are also regulatory projects underway for the European Union, which are considering the phase out of leaded fuel for the aviation industry earlier than the FAA timetable.

While we expect that at some point in the future a replacement fuel will be identified, trialed and supplied to the industry, there is no currently available alternative. If a suitable product is identified and the use of leaded fuel is prohibited in piston aviation the Company’s future operating income and cash flows from operating activities would be adversely impacted.

Failure to protect our intellectual property rights could adversely affect our future performance and cash flows.

Failure to maintain or protect our intellectual property rights may result in the loss of valuable technologies, or us having to pay other companies for infringing on their intellectual property rights. Measures taken by us to protect our intellectual property may be challenged, invalidated, circumvented or rendered unenforceable. In addition, international intellectual property laws may be more restrictive or may offer lower levels of protection than under U.S. law. We may also face patent infringement claims from our competitors which may result in substantial litigation costs, claims for damages or a tarnishing of our reputation even if we are successful in defending against these claims, which may cause our customers to switch to our competitors. Any of these events could adversely impact our results of operations, financial position and cash flows.

Industry Matters

Trends in oil and gas prices affect the level of exploration, development and production activity of our customers, and the demand for our services and products, which could have a material adverse impact on our business.

Demand for our services and products in our Oilfield Services business is particularly sensitive to the level of exploration, development and production activity of, and the

15

corresponding capital spending by, oil and gas companies. The level of exploration, development and production activity is directly affected by trends in demand for and prices of oil and gas, which historically have been volatile and are likely to continue to be volatile. Prices for oil and gas are subject to large fluctuations in response to relatively minor changes in the supply of and demand for oil and gas, market uncertainty, and a variety of other economic and political factors that are beyond our control. Even the perception of longer-term lower oil and gas prices by oil and gas companies can similarly reduce or defer major expenditures given the long-term nature of many large-scale development projects. Factors affecting the prices of oil and gas include, but are not limited to, the level of supply and demand for oil and gas; governmental regulations, including the policies of governments regarding the exploration for and production and development of their oil and gas reserves; weather conditions and natural disasters; worldwide political, military and economic conditions; the level of oil and gas production by non-OPEC (“Organization of the Petroleum Exporting Countries”) countries and the available excess production capacity within OPEC; the cost of producing and delivering oil and gas; and potential acceleration of the development of alternative power generation, fuels and engine technologies. Any prolonged reduction in oil and gas prices will depress the immediate levels of exploration, development and production activity, which could have a material adverse impact on our results of operations, financial position and cash flows.

We could be adversely affected by technological changes in our industry.

Our ability to maintain or enhance our technological capabilities, develop and market products and applications that meet changing customer requirements, and successfully anticipate or respond to technological changes in a cost effective and timely manner will likely impact our future business success. We compete on a number of fronts including, but not limited to, product quality and performance. In the case of some of our products, our competitors are larger than us and may have greater access to financial, technological and other resources. Technological changes include, but are not limited to, the development of electric and hybrid vehicles, and the subsequent impact on the demand for gasoline and diesel. Our inability to maintain a technological edge, innovate and improve our products could cause a decline in the demand and sales of our products, and adversely impact our results of operations, financial position and cash flows.

Sharp and unexpected fluctuations in the cost of our raw materials and energy could adversely affect our profit margins.

We use a variety of raw materials, chemicals and energy in our manufacturing and blending processes. Many of these raw materials are derived from petrochemical-based and vegetable-based feedstocks which can be subject to periods of rapid and significant cost instability. These fluctuations in cost can be caused by political instability in oil producing nations and elsewhere, weather conditions or other factors influencing global supply and demand of these materials, over which we have little or no control. We use long-term contracts (generally with fixed or formula-based costs) and advance bulk purchases to help ensure availability and continuity of supply, and to manage the risk of cost increases. From time to time, we have

16

entered into hedging arrangements for certain utilities and raw materials, but do not typically enter into hedging arrangements for all raw materials, chemicals or energy costs. If the costs of raw materials, chemicals or energy increase, and we are not able to pass on these cost increases to our customers, then profit margins and cash flows from operating activities would be adversely impacted. If raw material costs increase significantly, then our need for working capital could increase. Any of these risks could adversely impact our results of operations, financial position and cash flows.

Our business is subject to the risk of manufacturing disruptions, the occurrence of which would adversely affect our results of operations.

We are subject to hazards which are common to chemical manufacturing, blending, storage, handling and transportation. These hazards include, but are not limited to, fires, explosions, chemical spills and the release or discharge of toxic or hazardous substances together with the more generic risks of labor strikes or slowdowns, mechanical failure in scheduled downtime, extreme weather or transportation interruptions. These hazards could result in loss of life, severe injury, property damage, environmental contamination and temporary or permanent manufacturing cessation. Any of these factors could adversely impact our results of operations, financial position and cash flows.

Legal, Regulatory and Tax Matters

We are subject to extensive regulation of our international operations that could adversely affect our business and results of operations.

Due to our global operations, we are subject to many laws governing international commercial activity, conduct and relations, including, but are not limited to, those that prohibit improper payments to government officials, restrict where and with whom we can do business and limit the products, software and technology that we can supply to certain countries and customers. These laws include, but are not limited to, the U.S. Foreign Corrupt Practices Act and U.K. Bribery Act, sanctions and assets control programs administered by the U.S. Department of the Treasury and/or the European Union from time to time, and the U.S. export control laws such as the regulations under the U.S. Export Administration Act, as well as similar laws and regulations in other countries relevant to our business operations. Violations of any of these laws or regulations, which are often complex in their application, may result in criminal or civil penalties that could have a material adverse effect on our results of operations, financial position and cash flows.

Our United Kingdom defined benefit pension plan could adversely impact our financial condition, results of operations and cash flows.

Movements in the underlying plan asset value and Projected Benefit Obligation (“PBO”) of our United Kingdom defined benefit pension plan (“UK Plan”) are dependent on our assumptions in respect of the discount rate, annual member mortality rates, future return on assets and future inflation. A change in any one of these assumptions could impact the plan asset value, PBO and pension credit recognized in the income statement.

17

In May 2022, the Trustees of the UK Plan entered into an agreement with Legal and General Assurance Society Limited to acquire an insurance policy that operates as an investment asset, with the intent of matching the remaining uninsured part of the UK Plan’s future cash outflow arising from the accrued pension liabilities of members. Such an arrangement is commonly termed as a “buy-in”. The benefit obligation was not transferred to the insurer, and the Company remains responsible for paying pension benefits. The initial value of the asset associated with this contract was equal to the premium paid to secure the contract and is adjusted each reporting period to reflect the estimated fair value of the premium that would be paid for such a contract at that time. The buy-in reduces the UK Plan’s value at risk in relation to key risks associated with improved longevity, inflation and interest rate movements while improving the security to the UK Plan and its members. The Company consequently benefits from the buy-in as it reduces the UK Plan’s potential reliance on the Company for future cash funding requirements. However, should an unexpected issue arise, there could be consequences which adversely impact our results of operations, financial position and cash flows.

We may have additional tax liabilities.

We are subject to income and other taxes in the U.S., the U.K., and a number of other jurisdictions. Tax laws are dynamic and subject to change as new laws are passed and new interpretations of the law are issued or applied. Significant judgment is required in estimating our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our tax estimates are reasonable, any final determination pursuant to tax audits and any related litigation could be materially different to the amounts reflected in our Consolidated Financial Statements. Should any tax authority disagree with our estimates and determine any additional tax liabilities, including interest and penalties for us, this could adversely impact our results of operations, financial position and cash flows.

Our products are subject to extensive government scrutiny and regulation.

We are subject to regulation by federal, state, local and foreign government authorities. In some cases, we need government approval of our products, manufacturing processes and facilities before we may sell certain products. Many products are required to be registered with the U.S. Environmental Protection Agency (EPA), with the European Chemicals Agency (ECHA) and with comparable government agencies elsewhere. We are also subject to ongoing reviews of our products, manufacturing processes and facilities by government authorities, and must also produce product data and comply with detailed regulatory requirements.

In order to obtain regulatory approval of certain new products we must, among other things, demonstrate that the product is appropriate and effective for its intended uses, that the product has been appropriately tested for safety and that we are capable of manufacturing the product in accordance with applicable regulations. This approval process can be costly, time consuming, and subject to unanticipated and significant delays. We cannot be sure that necessary approvals will be granted on a timely basis or at all. Any delay in obtaining, or any

18

failure to obtain or maintain, these approvals would adversely affect our ability to introduce new products and to generate income from those products. New or stricter laws and regulations may be introduced that could result in additional compliance costs and prevent or inhibit the development, manufacture, distribution and sale of our products. Such outcomes could adversely impact our results of operations, financial position and cash flows.

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.

Legal proceedings and other claims could impose substantial costs on us.

We are from time to time involved in legal proceedings that result from, and are incidental to, the conduct of our business, including employee and product liability claims. Although we maintain insurance to protect us against a variety of claims, if our insurance coverage is not adequate to cover such claims, then we may be required to pay directly for such liabilities. Such outcomes could adversely impact our results of operations, financial position and cash flows.

Environmental liabilities and compliance costs could have a substantial adverse impact on our results of operations.

We operate a number of manufacturing sites and are subject to extensive federal, state, local and foreign environmental, health and safety laws and regulations, including, but not limited to, those relating to emissions to the air, discharges to land and water, and the generation, handling, treatment and disposal of hazardous waste and other materials on these sites. We operate under numerous environmental permits and licenses, many of which require periodic notification and renewal, which is not automatic. New or stricter laws and regulations could increase our compliance burden or costs and adversely affect our ability to develop, manufacture, blend, market and supply products.

Our operations, and the operations of prior owners of our sites, pose the risk of environmental contamination which may result in fines or criminal sanctions being imposed or require significant amounts in environmental remediation payments.

We anticipate that certain manufacturing sites may cease production over time and on closure, will require safely decommissioning and some environmental remediation. The extent of our obligations will depend on the future use of the sites that are affected and the environmental laws in effect at the time. We currently hold a plant closure provision in our Consolidated Financial Statements based on current known obligations, anticipated plans for sites or existing environmental laws. If there were to be unexpected or unknown contamination at these sites, or future plans for the sites or environmental laws change, then current provisions may prove inadequate, which could adversely impact our results of operations, financial position and cash flows.

19

We may be exposed to certain regulatory and financial risks related to climate change

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.

Key Third Party Relationships

Having a small number of significant customers may have a material adverse impact on our results of operations.

Our principal customers are personal and home care companies, oil refiners, oil and gas exploration and production companies, and other chemical and industrial companies. These industries are characterized by a concentration of a few large participants. The loss of a significant customer, a material reduction in demand by a significant customer or termination or non-renewal of a significant customer contract could adversely impact our results of operations, financial position and cash flows.

A disruption in the supply of raw materials or transportation services would have a material adverse impact on our results of operations.

Although we try to anticipate problems with supplies of raw materials or transportation services by building certain inventories of strategic importance, transport operations are exposed to various risks such as extreme weather conditions, natural disasters, technological problems, work stoppages, geopolitical tensions, pandemics, as well as transportation regulations. If the Company experiences transportation problems, or if there are significant changes in the cost of these services, the Company may not be able to arrange efficient alternatives and timely means to obtain raw materials or ship finished products, which could adversely impact our results of operations, financial position and cash flows.

The inability of counterparties to meet their contractual obligations could have a substantial adverse impact on our results of operations.

Credit limits, ongoing credit evaluation and account monitoring procedures are used to minimize bad debt risk. Collateral is not generally required. We have in place a credit facility with a syndicate of banks. From time to time, we use derivatives, including, but not limited to,

20

interest rate swaps, commodity swaps and foreign currency forward exchange contracts, in the normal course of business to manage market risks. We enter into derivative instruments with a diversified group of major financial institutions in order to manage the exposure to non-performance of such instruments.

We remain subject to market and credit risks including the ability of counterparties to meet their contractual obligations and the potential non-performance of counterparties to deliver contracted commodities or services at the contracted price. The inability of counterparties to meet their contractual obligations could have an adverse impact on our results of operations, financial position and cash flows.

Finance and Investment

We are exposed to fluctuations in foreign currency exchange rates, which may adversely affect our results of operations.

We generate a portion of our revenues and incur some operating costs in currencies other than the U.S. dollar. In addition, the financial position and results of operations of some of our overseas subsidiaries are reported in the relevant local currency and then translated to U.S. dollars at the applicable currency exchange rates for inclusion in our Consolidated Financial Statements. Fluctuations in these currency exchange rates affect the recorded levels of our assets and liabilities, results of operations and cash flows.

The primary exchange rate fluctuation exposures we have are with the E.U. euro, British pound sterling and Brazilian real. Exchange rates between these currencies and the U.S. dollar have fluctuated in recent years and may continue to do so. We cannot accurately predict future exchange rate variability among these currencies or relative to the U.S. dollar. While we take steps to manage currency exchange rate exposure, including entering into hedging transactions, we cannot eliminate all exposure to future exchange rate variability. These exchange risks could adversely impact our results of operations, financial position and cash flows.

A high concentration of significant stockholders may have a material adverse impact on our stock price.

Approximately 44% of our common stock is held by four stockholders. A decision by any of these, or other substantial, stockholders to sell all or a significant part of its holding, or a sudden or unexpected disposition of our stock, could result in a significant decline in our stock price. This could in turn adversely impact our ability to access equity markets, which could adversely impact our results of operations, financial position and cash flows.

21

Our amended and restated by-laws designate specific Delaware courts as the exclusive forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our amended and restated by-laws (the “By-laws”) provide that, unless we consent in writing to the selection of an alternative forum, the appropriate court within the State of Delaware is the sole and exclusive forum, to the fullest extent provided by law, for the following types of actions or proceedings:

• any derivative action or proceeding brought on behalf of the Corporation,

• any action asserting a claim of breach of a fiduciary duty owed by any director, officer, other employee or stockholder of the Corporation to the Corporation or the Corporation’s stockholders,

• any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law (“DGCL”), our amended and restated certificate of incorporation, the By-laws, or as to which the DGCL confers jurisdiction upon the Court of Chancery of the State of Delaware,

• any action asserting a claim governed by the internal affairs doctrine, or

• any other internal corporate claim as defined in Section 115 of the DGCL.

This includes, to the extent permitted by the federal securities laws, lawsuits asserting both state law claims and claims under the federal securities laws.

This forum selection provision in the By-laws may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us. It is also possible that, notwithstanding the forum selection clause included in the By-laws, a court could rule that such a provision is inapplicable or unenforceable.

Application of the choice of forum provision may be limited in some instances by law. Section 27 of the Securities Exchange Act of 1934 (“Exchange Act”) provides for exclusive federal court jurisdiction over Exchange Act claims. Accordingly, to the extent the exclusive forum provision is held to cover a shareholder derivative action asserting claims under the Exchange Act, such claims could not be brought in the Delaware Court of Chancery and would instead be within the jurisdiction of the federal district court for the District of Delaware. Section 22 of the Securities Act of 1933 (“Securities Act”) creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Our stockholders will not be deemed by operation of our choice of forum provision to have waived our compliance with the federal securities laws and the regulations promulgated thereunder. The selection of legal jurisdiction for litigation claims may impact the outcome of legal proceedings which could in turn impact our results of operations, financial position and cash flows.

22

The provisions of our revolving credit facility may restrict our ability to incur additional indebtedness or to otherwise expand our business.

Our revolving credit facility contains restrictive clauses which may limit our activities as well as operational and financial flexibility. We may not be able to borrow under the revolving credit facility if an event of default under the terms of the facility occurs. An event of default under the credit facility includes a material adverse change to our assets, operations or financial condition, and certain other events. The revolving credit facility also contains a number of restrictions that limit our ability, among other things, and subject to certain limited exceptions, to incur additional indebtedness, pledge our assets as security, guarantee obligations of third parties, make investments, undergo a merger or consolidation, dispose of assets or materially change our line of business.

In addition, the revolving credit facility requires us to meet certain financial ratios, including ratios based on net debt to earnings before income tax, depreciation and amortization (“EBITDA”) and net interest expense to EBITDA. Net debt, net interest expense and EBITDA are non-GAAP measures of liquidity defined in the credit facility. Our ability to meet these financial covenants depends upon the future successful operating performance of the business. If we fail to comply with these financial covenants, we would be in default under the revolving credit facility and the maturity of our outstanding debt could be accelerated unless we were able to obtain waivers from our lenders. If we were found to be in default under the revolving credit facility, it could adversely impact our results of operations, financial position and cash flows.

Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations

This discussion should be read in conjunction with our Consolidated Financial Statements and the Notes thereto.

EXECUTIVE OVERVIEW

In 2022 Innospec delivered double-digit sales and operating income growth with expanded margins, and each of our businesses contributed meaningfully to our results. We benefited from our balanced end-market exposure in late 2022 as the negative impact of year-end customer destocking in Performance Chemicals was offset by continued growth in Oilfield Services and Fuel Specialties.

In Performance Chemicals, despite aggressive customer destocking which drove lower volumes and margins in the fourth quarter, full-year operating income increased by 34 percent, and operating margin improved for the fifth consecutive year. Our industry-leading personal care technologies drove the majority of operating income growth in 2022.

Fuel Specialties delivered double-digit operating income growth for the full year. Gross margins remained below our expected range, but improvement continues to be a key focus and opportunity for our business in 2023. We believe there is potential for gross margin expansion once inflation normalizes and demand for our higher margin jet fuel additives recovers.

Oilfield Services achieved significant sales and operating income growth over the prior year. In 2023, we anticipate that a portion of our sales will moderate versus the extremely strong third and fourth quarters of 2022. However, we expect potential for further improvement in the other markets within our oilfield business.

CRITICAL ACCOUNTING ESTIMATES

Note 2 of the Notes to the Consolidated Financial Statements includes a summary of the significant accounting policies and methods used in the preparation of the consolidated financial statements.

Plant Closure Provisions

We are subject to environmental laws in the countries in which we conduct business. Ellesmere Port in the United Kingdom is our principal site giving rise to asset retirement obligations, associated with the production of TEL. There are also asset retirement obligations and environmental remediation liabilities on a much smaller scale in respect of other manufacturing sites. At Ellesmere Port there is a continuing asset retirement program related to certain manufacturing units that have been closed.

Plant closure provisions at December 31, 2022 amounted to $57.2 million and relate principally to our Ellesmere Port site in the United Kingdom. We recognize environmental

29

remediation liabilities when they are probable and costs can be reasonably estimated, and asset retirement obligations when there is a legal requirement, including those arising from a Company promise, and the costs can be reasonably estimated. The Company has to anticipate the program of work required and the associated future expected costs, and comply with environmental legislation in the countries in which it operates or has operated in. We develop these assumptions utilizing the latest information available together with recent costs. While we believe our assumptions for plant closure provisions are reasonable, they are subjective estimates and it is possible that variations in any of the assumptions will result in materially different calculations to the liabilities we have reported.

Income Taxes

We are subject to income and other taxes in the U.S., the U.K., and a number of other jurisdictions. Tax laws are dynamic and subject to change as new laws are passed and new interpretations of the law are issued or applied.

The calculation of our tax liabilities involves evaluating uncertainties in the application of accounting principles and complex tax regulations. We recognize liabilities for anticipated tax audit issues based on our estimate of whether, and the extent to which, additional taxes will be required. If we ultimately determine that payment of these amounts is unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary.

We also recognize tax benefits to the extent that it is more likely than not that our positions will be sustained, based on technical merits of the position, when challenged by the taxing authorities. To the extent that we prevail in matters for which liabilities have been established or are required to pay amounts in excess of the liabilities recorded in our financial statements, our effective tax rate in a given period may be materially affected. An unfavorable tax settlement may require cash payments and result in an increase in our effective tax rate in the year of resolution. We report interest and penalties related to uncertain tax positions as income taxes. For additional information regarding uncertain income tax positions, see Note 11 of the Notes to the Consolidated Financial Statements.

Pensions

The Company maintains a defined benefit pension plan covering certain current and former employees in the United Kingdom (“UK Plan”). The UK Plan is closed to future service accrual but has a large number of deferred and current pensioners. The Company also has other smaller pension arrangements in the U.S. and overseas.

In May 2022, the Trustees of the UK Plan entered into an agreement with Legal and General Assurance Society Limited to acquire an insurance policy that operates as an investment asset, with the intent of matching the remaining uninsured part of the UK Plan’s future cash outflow arising from the accrued pension liabilities of members. Such an arrangement is commonly termed as a “buy-in”. The benefit obligation was not transferred to the insurer, and the Company remains responsible for paying pension benefits. The initial value of the asset associated with this contract was equal to the premium paid to secure the contract and is

30

adjusted each reporting period to reflect the estimated fair value of the premium that would be paid for such a contract at that time. The buy-in reduces the UK Plan’s value at risk in relation to key risks associated with improved longevity, inflation and interest rate movements while improving the security to the UK Plan and its members. The Company consequently benefits from the buy-in as it reduces the UK Plan’s potential reliance on the Company for future cash funding requirements.

Movements in the UK Plan’s Projected Benefit Obligation (“PBO”) are dependent on our assumptions in respect of the discount rate, annual member mortality rates, future return on assets and future inflation. A change in any one of these assumptions could impact the plan asset value, PBO and pension charge recognized in the income statement. Such changes could adversely impact our results of operations and financial position. For example, a 0.25% change in the discount rate assumption would change the PBO at December 31, 2022 by approximately $10.3 million and the net pension credit for 2023 would change by approximately $0.1 million. A 0.25% change in the level of price inflation assumption would change the PBO at December 31, 2022 by approximately $6.5 million and the net pension credit for 2022 by approximately $0.6 million.

Further information is provided in Note 10 of the Notes to the Consolidated Financial Statements.

Goodwill

The Company’s reporting units, the level at which goodwill is assessed for potential impairment, are consistent with the reportable segments. The components in each segment (including products, markets and competitors) have similar economic characteristics and the segments, therefore, reflect the lowest level at which operations and cash flows can be sufficiently distinguished, operationally and for financial reporting purposes, from the rest of the Company.

To test for impairment the Company performs a qualitative step zero assessment to determine whether it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a segment is less than the carrying amount prior to performing the quantitative goodwill impairment test. Factors utilized in the qualitative assessment process include macroeconomic conditions; industry and market considerations; cost factors; overall financial performance; and Company specific events.

If a quantitative test is required, we assess the fair value based on projected post-tax cash flows discounted at the Company’s weighted average cost of capital. These fair value techniques require management judgment and estimates including revenue growth rates, projected operating margins, changes in working capital and discount rates. We would develop these assumptions by considering recent financial performance and trends and industry growth estimates. While we believe our assumptions for impairment assessments are reasonable, they are subjective judgments, and it is possible that variations in any of the assumptions will result in materially different calculations of any potential impairment charges.

31

At December 31, 2022 we had $358.8 million of goodwill relating to our Performance Chemicals, Fuel Specialties and Oilfield Services segments. Our step zero impairment review at December 31, 2022 indicated the fair value of each segment is, more likely than not, higher than the carrying value, meaning no step one impairment review was required to be performed.

Property, Plant and Equipment and Other Intangible Assets (Net of Depreciation and Amortization, respectively)

As at December 31, 2022 we had $220.9 million of property, plant and equipment and $45.0 million of other intangible assets (net of depreciation and amortization, respectively), that are discussed in Notes 6 and 9 of the Notes to the Consolidated Financial Statements, respectively. These long-lived assets relate to all of our reporting segments and are being amortized or depreciated straight-line over periods of up to 17 years in respect of the other intangible assets and up to 25 years in respect of the property, plant and equipment.

We continually assess the markets and products related to these long-lived assets, as well as their specific carrying values, and have concluded that these carrying values, and amortization and depreciation periods, remain appropriate.

Performance Chemicals

Net sales: the table below details the components which comprise the year over year change in net sales spread across the markets in which we operate:

Change (%)	Americas		EMEA		ASPAC		Total
Volume		+20		-9		+7		+2
Price and product mix		+20		+33		+18		+28
Exchange rates		—		-14		-7		-8
		+40		+10		+18		+22

Higher sales volumes for the Americas and ASPAC were primarily driven by increased demand for our personal care products. Lower sales volumes for EMEA were due to

34

reductions in demand for our home care products when compared to strong sales volumes in the prior year. All our regions benefited from a favorable price and product mix due to increased sales of higher priced products together with the impact of increased raw materials pricing being passed on through higher selling prices. EMEA and ASPAC were adversely impacted by exchange rate movements year over year, due to a strengthening of the U.S. dollar against the British pound sterling and the European Union euro.

Gross margin: the year over year decrease of 0.4 percentage points was primarily due to adverse manufacturing variances and higher raw materials costs in the fourth quarter of 2022, being partly offset by a favorable sales mix from increased sales of higher margin products.

Operating expenses: the year over year increase of $0.4 million was due to higher selling expenses to support our increased sales and higher personnel-related expenses, including higher share-based compensation accruals and higher performance-related remuneration accruals; being partly offset by lower provisions for doubtful debts.

Fuel Specialties

Net sales: the table below details the components which comprise the year over year change in net sales spread across the markets in which we operate:

Change (%)	Americas		EMEA		ASPAC		AvGas		Total
Volume		+10		-11		+11		+4		—
Price and product mix		+28		+32		+14		-7		+26
Exchange rates		—		-17		-4		—		-8
		+38		+4		+21		-3		+18

The Americas and ASPAC sales volumes have increased year over year as the global demand for refined fuel products has increased. EMEA sales volumes were lower year over year primarily due to a reduction for the sales of higher volume lower margin products. Price and product mix was favorable in all our regions due to a favorable sales mix with an increased proportion of sales of higher margin products, together with the impact of increased raw materials pricing being passed on through higher selling prices. AvGas volumes were higher than the prior year due to variations in the demand from customers, being offset by an adverse price and product mix with a higher proportion of sales being made to lower margin customers. EMEA and ASPAC were adversely impacted by exchange rate movements year over year, due to a strengthening of the U.S. dollar against the British pound sterling and the European Union euro.

Gross margin: the year over year decrease of 0.8 percentage points was due to the impact of the time lag for passing higher raw material costs through to selling prices.

Operating expenses: the year over year increase of $11.6 million was due to higher personnel-related expenses, including higher share-based compensation accruals, higher travel expenses, increased sales promotions and increased provisions for doubtful debts.

35

Oilfield Services

Net sales: have increased year over year by $254.0 million, or 75 percent, with the majority of our customer activity being concentrated in the Americas region. Customer demand has increased through each quarter in 2022, which we believe represents a positive sign for further sales growth going into 2023.

Gross margin: the year over year increase of 1.9 percentage points was due to a favorable sales mix, while management are continuing to maintain prices in a competitive market.

Operating expenses: the year over year increase of $67.0 million was driven by higher customer service costs which are necessary to support the increase in demand, together with higher personnel-related expenses, including higher share-based compensation accruals and higher performance-related remuneration accruals, and increased provisions for doubtful debts.

Other Income Statement Captions

Corporate costs: the year over year increase of $15.8 million was driven by higher personnel-related expenses, including higher share-based compensation accruals and higher performance-related remuneration accruals, together with increased maintenance expenditure for our information technology infrastructure.

Profit on disposal: in the prior year there was a profit on disposal of $1.8 million, which principally related to the sale of land within our oilfield services business in the U.S..

Other net income/(expense): for 2022 and 2021, includes the following:

(in millions)	2022			2021			Change
Net pensions credit	$	4.8		$	5.4		$	(0.6	)
Foreign exchange gains/(losses) on translation		(7.1	)		(2.6	)		(4.5	)
Foreign currency forward contracts gains/(losses)		0.7			1.0			(0.3	)
	$	(1.6	)	$	3.8		$	(5.4	)

Interest expense, net: was $1.1 million in 2022 compared to $1.5 million in 2021. Interest expense includes a commitment fee to retain the Company’s revolving credit facility for the term of the agreement.

Income taxes: The effective tax rate was 28.0% and 30.7% in 2022 and 2021, respectively. The adjusted effective tax rate, once adjusted for the items set out in the following table, was 27.0% in 2022 compared with 22.7% in 2021. The Company believes that this adjusted effective tax rate, a non-GAAP financial measure, provides useful information to investors and may assist them in evaluating the Company’s underlying performance and identifying operating trends. In addition, management uses this non-GAAP financial measure internally to evaluate the performance of the Company’s operations and for planning and forecasting in subsequent periods.

Adjusted income taxes	$	52.6			32.5
GAAP effective tax rate		28.0	%		30.7	%
Adjusted effective tax rate		27.0	%		22.7	%

The GAAP effective tax rate and adjusted effective tax rate in 2022 have been negatively impacted by foreign income inclusions, net of foreign tax credits, which arise each year from certain types of income earned overseas being taxable under U.S. tax regulations.

As a consequence of the Company having operations outside of the U.S., it is exposed to foreign currency fluctuations. These have also had a negative impact on the GAAP effective tax rate and adjusted effective tax rate in 2022.

The adjusted effective tax rate is lower than the GAAP effective tax rate, primarily due to elimination of stock compensation activity to better reflect the Company’s underlying business performance.

The most significant factor impacting our adjusted effective tax rate in 2021 is the elimination of the impact of the increase in the U.K. statutory income tax rate.

For additional information regarding the GAAP effective tax rate in 2022, see Note 11 of the Notes to the Consolidated Financial Statements.

Higher volumes for the Americas were driven by increased demand for our personal care products. Volumes in EMEA were favorable including the continued recovery of demand across several markets which have been adversely impacted by the pandemic. Lower volumes in ASPAC were primarily driven by a reduction in demand for our personal care products. All our regions benefited from a favorable price and product mix due to increased sales of higher priced products and increased raw materials pricing being passed on through higher selling prices. EMEA and ASPAC benefited from favorable exchange rate movements year over year, due to a strengthening of the British pound sterling and the European Union euro against the U.S. dollar.

Gross margin: the year over year decrease of 0.6 percentage points was due to adverse manufacturing variances as activity slowed over the holiday season in the fourth quarter, together with some one-off provisions.

Operating expenses: the year over year increase of $5.3 million was due to increased spending on research and development, an increase in the allowance for doubtful debts and higher personnel-related expenses including higher share-based compensation accruals and higher performance related remuneration accruals.

Volumes in all our regions have increased year over year, as the global demand for refined fuel products has returned to near the pre-pandemic levels. Price and product mix was favorable in all our regions due to increased sales of higher margin products and increased raw materials pricing being passed on through higher selling prices. AvGas volumes were lower than the prior year due to variations in the demand from customers, being offset by a favorable price and product mix with a higher proportion of sales to higher margin customers. EMEA and ASPAC benefited from favorable exchange rate movements year over year, due to a strengthening of the British pound sterling and the European Union euro against the U.S. dollar.

Gross margin: the year over year decrease of 0.1 percentage points was impacted by the time lag for passing higher raw material costs through to selling prices in the second half of the year.

Operating expenses: the year over year increase of $12.8 million was due to higher selling expenses to support the increased sales, together with higher research and development costs

39

and higher personnel-related expenses including higher share-based compensation accruals and higher performance related remuneration accruals.

Oilfield Services

Net sales: have increased year over year by $84.8 million, or 33 percent, with the majority of our customer activity continuing to be in the Americas region. Customer demand has increased throughout the year as the pandemic recovery has continued. We expect to see continued growth in customer demand into 2022.

Gross margin: the year over year increase of 2.6 percentage points was due to a favorable sales mix compared to a prior year comparative which was adversely impacted by the pandemic, while management have successfully maintained prices in a competitive market.

Operating expenses: the year over year increase of $15.8 million was driven by our continuing customer service flexibility which allows us to support the increase in demand as the pandemic recovery has continued, together with higher personnel-related expenses including higher share-based compensation accruals and higher performance related remuneration accruals.

Octane Additives

The Octane Additives business ceased trading and is no longer a reporting segment from July 1, 2020 as the production of TEL for use in motor gasoline has finished. Legacy costs related to these operations have now been recorded as operating expenses within corporate costs.

Prior to the business ceasing trade there were no sales in 2020, together with a gross loss of $2.2 million and operating expenses of $0.6 million.

Other Income Statement Captions

Corporate costs: the year over year increase of $3.4 million was driven by higher personnel-related expenses including higher share-based compensation accruals and higher performance related remuneration accruals, together with the adverse impact of the foreign currency translation of our costs at Ellesmere Port in the United Kingdom due to a strengthening of the British pound sterling against the U.S. dollar.

Profit on disposal: there has been a profit on disposal of assets for $1.8 million in 2021, which principally relates to the sale of land within our oilfield services business in the U.S..

Interest expense, net: was $1.5 million in 2021 compared to $1.8 million in 2020, driven by the repayment in full of our revolving credit facility in the second half of 2020. Interest expense includes a commitment fee to retain the Company’s revolving credit facility for the term of the agreement.

Income taxes: The effective tax rate was 30.7% and 27.7% in 2021 and 2020, respectively. The adjusted effective tax rate, once adjusted for the items set out in the following table, was 22.7% in 2021 compared with 23.5% in 2020. The Company believes that this adjusted effective tax rate, a non-GAAP financial measure, provides useful information to investors and may assist them in evaluating the Company’s underlying performance and identifying operating trends.

The most significant factor impacting our adjusted effective tax rate in 2021 is the elimination of the impact of the increase in the statutory income tax rate in the U.K..

The most significant factors impacting our adjusted effective tax rate in 2020 are the restructuring charge relating to the cessation of production and sales of TEL for use in motor gasoline, the impairment of acquired intangible assets in our Oilfield Services segment, and the elimination of the impact of the increase in the statutory income tax rate in the U.K..

LIQUIDITY AND FINANCIAL CONDITION

Working Capital

In 2022 our working capital increased by $75.3 million, while our adjusted working capital increased by $88.7 million. The difference is primarily due to the exclusion of the increase in our cash and cash equivalents, together with the movements for income taxes.

The Company believes that adjusted working capital, a non-GAAP financial measure, provides useful information to investors in evaluating the Company’s underlying performance and identifying operating trends. Management uses this non-GAAP financial measure internally to allocate resources and evaluate the performance of the Company’s operations. Items excluded from the adjusted working capital calculation are listed in the table below and

The movements in our adjusted working capital are explained as follows:

We had a $50.1 million increase in trade and other accounts receivable primarily driven by increased trading activity across our reporting segments. Days’ sales outstanding in our Performance Chemicals segment decreased from 64 days to 60 days; increased in our Fuel Specialties segment from 53 days to 54 days; and increased from 52 days to 54 days in our Oilfield Services segment.

We had a $95.5 million increase in inventories, net of a $1.7 million increase in allowances, as we managed inventory levels to support future demand, with the intention of mitigating the risk of potential supply chain disruption for certain key raw materials. Days’ sales in inventory in our Performance Chemicals segment increased from 59 days to 78 days; increased in our Fuel Specialties segment from 108 days to 138 days; and decreased from 76 days to 58 days in our Oilfield Services segment.

Prepaid expenses decreased $3.9 million, from $18.0 million to $14.1 million principally due to the reduction in prepaid customer marketing arrangements.

We had a $53.0 million increase in accounts payable and accrued liabilities primarily due to increased activity across all our reporting segments. Creditor days (including goods received not invoiced) decreased in our Performance Chemicals segment from 47 days to 42 days; decreased in our Fuel Specialties segment from 50 days to 45 days; and increased from 48 days to 54 days in our Oilfield Services segment.

Operating Cash Flows

We generated cash from operating activities of $81.7 million in 2022 compared to cash inflows of $93.2 million in 2021. The reduction in cash generated from operating activities

43

was primarily related to the increases for our working capital being partly offset by the improvements in our earnings before depreciation and amortization.

Cash

At December 31, 2022 and 2021, we had cash and cash equivalents of $147.1 million and $141.8 million, respectively, of which $76.4 million and $55.1 million, respectively, were held by non-U.S. subsidiaries principally in the United Kingdom.

The $5.3 million increase in cash and cash equivalents in 2022 was driven by the cash inflows from operating activities, while being partly offset by increased working capital levels, continued investments in capital projects and the payment of our semi-annual dividends.

Debt

As at December 31, 2022 and December 31, 2021 the Company had repaid all of its borrowings under the revolving credit facility and as a result, the related deferred finance costs of $0.6 million (December 31, 2021 – $1.0 million) are now included within other current and non-current assets at the balance sheet date.

On September 16, 2020, Innospec and certain of its subsidiaries agreed to extend the term of its revolving credit facility, as described below, until September 25, 2024. The costs of $0.3 million for extending the term have been capitalized on the balance sheet, which are being amortized over the expected life of the facility.

On September 30, 2019 the Company repaid its pre-existing term loan and revolving credit facility that had been amended and restated on December 14, 2016, and replaced this borrowing with the new credit facility. As a result, refinancing costs of $1.5 million were capitalized which are being amortized over the expected life of the facility.

On September 26, 2019, Innospec and certain of its subsidiaries entered into a new agreement for a $250.0 million revolving credit facility until September 25, 2023 with an option to request an extension to the facility for a further year. The facility also contains an accordion feature whereby the Company may elect to increase the total available borrowings by an aggregate amount of up to $125.0 million.

The revolving credit facility contains terms which, if breached, would result in it becoming repayable on demand. It requires, among other matters, compliance with the following financial covenant ratios measured on a quarterly basis: (1) our ratio of net debt to EBITDA must not be greater than 3.0:1.0 and (2) our ratio of EBITDA to net interest must not be less than 4.0:1.0 Management has determined that the Company has not breached these covenants and does not expect to breach these covenants for the next 12 months.

The revolving credit facility contains restrictions which may limit our activities as well as operational and financial flexibility. We may not be able to borrow if an event of default is outstanding, which includes a material adverse change to our assets, operations or financial

44

condition. The credit facility contains a number of restrictions that limit our ability, among other things, and subject to certain limited exceptions, to incur additional indebtedness, pledge our assets as security, guarantee obligations of third parties, make investments, effect a merger or consolidation, dispose of assets, or materially change our line of business.

At December 31, 2022, we had no debt outstanding under the revolving credit facility and no obligations under finance leases.

Contractual Commitments

The following represents contractual commitments at December 31, 2022 and the effect of those obligations on future cash flows:

Internally developed software		25.0		20.5		4.5		—		—
Total	$	112.3	$	66.8	$	27.9	$	5.6	$	12.0

Operating activities

Operating lease commitments relate primarily to right-of-use assets at third party manufacturing facilities, office space, motor vehicles and various items of computer and office equipment which are expected to be renewed and replaced in the normal course of business.

The estimated payments on debt are the commitment fees for our $250.0 million revolving credit facility. Any interest income has been excluded.

Due to the uncertainty regarding the nature of tax audits, particularly those which are not currently underway, it is not meaningful to predict the outcome of obligations related to unrecognized tax benefits. Further disclosure is provided in Note 11 of the Notes to the Consolidated Financial Statements.

Investing activities

Capital commitments relate to certain capital projects that the Company has committed to undertake.

Internally developed software relates to the planned completion costs for the implementation of our new Enterprise Resource Planning system for EMEA and ASPAC, including the acquisition costs for the software as well as the external and internal costs of the development.

Outlook

Despite the general recessionary outlook for 2023, we continue to anticipate technology-based organic growth opportunities across all our businesses. Over the medium to long-term, we do not expect any change in our customers’ drive towards cleaner formulations, lower carbon footprint and operational efficiency. We plan to continue our investment in R&D to improve our products and technology. Our innovative chemistries and highly-responsive technical service directly support our customers’ priorities.

Our strong balance sheet gives us the flexibility to move in parallel on all of our capital allocation priorities. In 2023, we expect to substantially complete our $70 million Performance Chemicals expansion while continuing dividend growth and, based on our assessment of market conditions, share repurchases. In parallel, we intend to continue to pursue potential acquisitions that complement and expand our geographic, technology and end-market footprint.

Environmental Matters and Plant Closures

Under certain environmental laws the Company is responsible for the environmental remediation of hazardous substances or wastes at currently or formerly owned or operated properties.

As most of our manufacturing operations have been conducted outside the U.S., we expect that liability pertaining to the investigation and environmental remediation of contaminated properties is likely to be determined under non-U.S. law.

We evaluate costs for environmental remediation, decontamination and demolition projects on a regular basis. Full provision is made for those costs amounting to $57.2 million at December 31, 2022. See Note 13 of the Notes to the Consolidated Financial Statements for further details. Expenditure utilizing these provisions was $4.2 million, $5.3 million and $4.1 million in the years 2022, 2021 and 2020, respectively.

Item 7A Quantitative and Qualitative Disclosures about Market Risk

The Company uses floating rate debt to finance its global operations. The Company is subject to business risks inherent in non-U.S. activities, including political and economic uncertainty, import and export limitations, and market risk related to changes in interest rates and foreign currency exchange rates. The political and economic risks are mitigated by the stability of the countries in which the Company’s largest operations are located. Credit limits, ongoing credit evaluation and account monitoring procedures are used to minimize bad debt risk. Collateral is not generally required.

From time to time, the Company uses derivatives, including interest rate swaps, commodity swaps and foreign currency forward exchange contracts, in the normal course of business to manage market risks. The derivatives used in hedging activities are considered risk management tools and are not used for trading purposes. In addition, the Company enters into derivative instruments with a diversified group of major financial institutions in order to manage the exposure to non-performance of such instruments. The Company’s objective in managing the exposure to changes in interest rates is to limit the impact of such changes on earnings and cash flows and to lower overall borrowing costs. The Company’s objective in managing the exposure to changes in foreign currency exchange rates is to reduce volatility on earnings and cash flows associated with such changes.

The Company offers fixed prices for some long-term sales contracts. As manufacturing and raw material costs are subject to variability the Company may use commodity swaps to hedge the cost of some raw materials thus reducing volatility on earnings and cash flows. The derivatives are considered risk management tools and are not used for trading purposes. The Company’s objective is to manage its exposure to fluctuating costs of raw materials.

Interest Rate Risk

From time to time, the Company uses interest rate swaps to manage interest rate exposure. The Company retains a $250.0 million revolving credit facility which is available to draw down as required. The credit facility carries an interest rate based on U.S. dollar LIBOR plus a margin of between 1.05% and 2.30% which is dependent on the Company’s ratio of net debt to EBITDA. Net debt and EBITDA are non-GAAP measures of liquidity defined in the credit facility.

At December 31, 2022, $0.0 million was drawn under the revolving credit facility.

The Company previously entered into interest rate swap contracts to reduce interest rate risk on its core debt. As at December 31, 2022 and December 31, 2021, there were no interest rate swaps in place. Interest rate swaps have previously been used to hedge interest rate risk on a term loan for a notional value that matched the repayment profile of the term loan.

As at December 31, 2022, the Company had no debt or finance leases and $147.1 million cash and cash equivalents. Assuming variable interest returns on the cash balances, a hypothetical absolute increase or decrease of 1% in U.S. base interest rates for a one-year period would increase or decrease net income and cash flows by approximately $1.5 million before tax.

47

The above does not consider the effect of interest or exchange rate changes on overall activity nor management action to mitigate such changes.

Exchange Rate Risk

The Company generates an element of its revenues and incurs some operating costs in currencies other than the U.S. dollar. The reporting currency of the Company is the U.S. dollar.

The Company evaluates the functional currency of each reporting unit according to the economic environment in which it operates. Several major subsidiaries of the Company operating outside of the U.S. have the U.S. dollar as their functional currency due to the nature of the markets in which they operate. In addition, the financial position and results of operations of some of our overseas subsidiaries are reported in the relevant local currency and then translated to U.S. dollars at the applicable currency exchange rate for inclusion in our Consolidated Financial Statements.

The primary foreign currencies in which we have exchange rate fluctuation exposure are the European Union euro, British pound sterling and Brazilian Real. Changes in exchange rates between these foreign currencies and the U.S. dollar will affect the recorded levels of our assets and liabilities, to the extent that such figures reflect the inclusion of foreign assets and liabilities which are translated into U.S. dollars for presentation in our Consolidated Financial Statements, as well as our results of operations.

The Company’s objective in managing the exposure to foreign currency fluctuations is to reduce earnings and cash flow volatility associated with foreign currency exchange rate changes. Accordingly, the Company enters into various contracts that change in value as foreign currency exchange rates change to protect the U.S. dollar value of its existing foreign currency denominated assets, liabilities, commitments, and cash flows. The Company also uses foreign currency forward exchange contracts to offset a portion of the Company’s exposure to certain foreign currency denominated revenues so that gains and losses on these contracts offset changes in the U.S. dollar value of the related foreign currency denominated revenues. The objective of the hedging program is to reduce earnings and cash flow volatility related to changes in foreign currency exchange rates.

The trading of our Performance Chemicals, Fuel Specialties and Oilfield Services segments is inherently naturally hedged and accordingly changes in exchange rates would not be material to our earnings or financial position. The cost base of our corporate costs, however, are largely denominated in British pound sterling. A 5% strengthening in the U.S. dollar against British pound sterling would increase reported operating income by approximately $1.6 million for a one-year period excluding the impact of any foreign currency forward exchange contracts. Where a 5% strengthening of the U.S. dollar has been used as an illustration, a 5% weakening would be expected to have the opposite effect on operating income.

48

Raw Material Cost Risk

We use a variety of raw materials, chemicals and energy in our manufacturing and blending processes. Many of the raw materials that we use are derived from petrochemical-based and vegetable-based feedstocks which can be subject to periods of rapid and significant cost instability. These fluctuations in cost can be caused by political instability in oil producing nations and elsewhere, or other factors influencing global supply and demand of these materials, over which we have little or no control. We use long-term contracts (generally with fixed or formula-based costs) and advance bulk purchases to help ensure availability and continuity of supply, and to manage the risk of cost increases. From time to time we enter into hedging arrangements for certain raw materials, but do not typically enter into hedging arrangements for all raw materials, chemicals or energy costs. Should the costs of raw materials, chemicals or energy increase, and should we not be able to pass on these cost increases to our customers, then operating margins and cash flows from operating activities would be adversely impacted. Should raw material costs increase significantly, then the Company’s need for working capital could similarly increase. Any of these risks could adversely impact our results of operations, financial position and cash flows.

Item 8 Financial Statements and Supplementary Data

Report of Independent Registered Public Accounting Firm

To theBoard of Directors and Stockholders of Innospec Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Innospec Inc. and its subsidiaries (the “Company”) as of December 31, 2022, and 2021, and the related consolidated statements of income, comprehensive income, equity and cash flowsfor each of the three years in the period ended December 31, 2022, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in

Internal Control – Integrated Framework

(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in

Internal Control – Integrated Framework

(2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included inManagement’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to

50

error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

51

Plant Closure Provisions

As described in Notes 2 and 13 to the consolidated financial statements, at December 31, 2022, the Company has recognized plant closure provisions of $57.2 million, the majority of which relates to asset retirement obligations. The Company recognizes asset retirement obligations when there is an obligation based on a legal requirement, including those arising from Company promises, and the costs can be reasonably estimated. The Company must comply with environmental legislation in the countries in which it operates or has operated in and annually reassesses the program of work required. This includes estimating the credit-adjusted risk free rate and the timing and cost of performing the remediation work. Management receives input from specialists to develop these estimates and assumptions utilizing the latest information available together with experience of recent costs.

The principal considerations for our determination that performing procedures relating to the plant closure provisions is a critical audit matter are: (i) the significant judgment made by management when developing the estimate; (ii) a high degree of auditor judgment and subjectivity in applying procedures relating to the recognition and measurement of the asset retirement obligations; (iii) the audit effort involved the use of professionals with specialized skill and knowledge; and (iv) the significant audit effort in evaluating the significant assumptions related to: the program of work required; and the timing and cost of performing the remediation work.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the recognition and measurement of the plant closure provisions. These procedures also included, among others: (i) testing management’s process to recognize and measure the estimate; (ii) evaluating the appropriateness of the valuation method; (iii) testing the data used in the calculation of the estimate; (iv) evaluating the reasonableness of significant assumptions including the assessment of the program of work required; the timing and cost of performing the remediation work; and the credit-adjusted risk-free rate; and (iv) evaluating the scope, competency, and objectivity of management’s specialists based on the work they were engaged to perform. Professionals with specialized skill and knowledge were used to assist in evaluating management’s method and the reasonableness of the significant assumptions in respect of the program of the work required and the timing and cost of performing the remediation work.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Note 1.     Nature of Operations

Innospec develops, manufactures, blends, markets and supplies a wide range of specialty chemicals to markets in the Americas, Europe, the Middle East, Africa and Asia-Pacific. Our Performance Chemicals business creates innovative technology-based solutions for our customers in the personal care, home care, agrochemical, mining and industrial markets. Our Fuel Specialties business specializes in manufacturing and supplying fuel additives that improve fuel efficiency, boost engine performance and reduce harmful emissions. Our Oilfield Services business supplies drilling, completion and production chemicals which make exploration and production more effective, cost-efficient and environmentally friendly.

Note 2.     Accounting Policies

Basis of preparation:

The consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States of America on a going concern basis and include all subsidiaries of the Company where the Company has a controlling financial interest. All intercompany accounts and balances have been eliminated upon consolidation. In accordance with GAAP in the United States of America, the results of operations of an acquired or disposed business are included or excluded from the consolidated financial statements from the date of acquisition or disposal.

Use of estimates:

The preparation of the consolidated financial statements, in accordance with GAAP in the United States of America, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Revenue recognition:

Our revenues are primarily derived from the manufacture and sale of specialty chemicals. We recognize revenue when control of the product is transferred to our customer and for an amount that reflects the consideration we expect to collect from the customer. Control is generally transferred to the customer when title transfers (which may include physical possession by the customer), we have a right to payment from the customer, the customer has accepted the product, and the customer has assumed the risks and rewards of ownership. We have supplier managed inventory arrangements with some of our customers to facilitate

on-demand

product availability. In some cases, the inventory resides at a customer site, although title has not transferred, we are not entitled to payment, and we have not invoiced for the product. We have evaluated the contract terms under these arrangements and have determined that control transfers when the customer uses the product, at which time revenue is recognized. Our contracts generally include one performance obligation, which is providing specialty chemicals. The performance obligation is satisfied at a point in time when products are shipped, delivered, or consumed by the customer, depending on the underlying contracts.

While some of our customers have payment terms beyond 30 days, we do not provide extended payment terms of a year or more, nor do our contracts include a financing component. Some of our contracts include variable consideration in the form of rebates. We

5

8

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

record rebates at the point of sale as a reduction in sales when we can reasonably estimate the amount of the rebate. The estimates are based on our best judgment at the time of sale, which includes anticipated as well as historical performance.

Taxes assessed by a governmental authority which are concurrent with sales to our customers, including sales, use, value-added, and revenue-related excise taxes, are collected by us from the customer and are not included in net sales, but are reflected in accrued liabilities until remitted to the appropriate governmental authority. When we are responsible for shipping and handling costs after title has transferred, we account for those as fulfilment costs and include them in cost of goods sold.

Components of net sales:

All amounts billed to customers relating to shipping and handling are classified as net sales. Shipping and handling costs incurred by the Company are classified as cost of goods sold.

Components of cost of goods sold:

Cost of goods sold is comprised of raw material costs including inbound freight, duty and

non-recoverable

taxes, inbound handling costs associated with the receipt of raw materials, packaging materials, manufacturing costs including labor costs, maintenance and utility costs, plant and engineering overheads, amortization expense for certain other intangible assets, warehousing and outbound shipping costs and handling costs. Inventory losses and provisions and the costs of customer claims are also recognized in the cost of goods line item.

Components of selling, general and administrative expenses:

Selling expenses comprise the costs of the direct sales force, and the sales management and customer service departments required to support them. It also comprises commission charges, the costs of sales conferences and trade shows, the cost of advertising and promotions, amortization expense for certain other intangible assets, and the cost of bad and doubtful debts. General and administrative expenses comprise the cost of support functions including accounting, human resources, information technology and the cost of group functions including corporate management, finance, tax, treasury, investor relations and legal departments. Provision of management’s best estimate of legal and settlement costs for litigation in which the Company is involved is accounted for in the administrative expense line item.

Research and development expenses:

Research, development and testing costs are expensed to the income statement as incurred.

Earnings per share:

Basic earnings per share is based on the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the effect of options that are dilutive and outstanding during the period.

Foreign currencies:

The Company’s policy is that foreign exchange differences arising on the translation of the balance sheets of entities that have functional currencies other than the U.S. dollar are taken to a separate equity reserve, the cumulative translation adjustment. In entities

5

9

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

where the U.S. dollar is the functional currency no gains or losses on translation occur, and gains or losses on monetary assets relating to currencies other than the U.S. dollar are taken to the income statement in other income/(expense), net. Gains and losses on intercompany foreign currency loans which are long-term in nature, which the Company does not intend to settle in the foreseeable future, are also recorded in accumulated other comprehensive loss. Other foreign exchange gains or losses are also included in other income, net in the income statement.

Share

-based compensation plans:

The Company accounts for employee stock options and stock equivalent units under the fair value method. Stock options are fair valued at the grant date and the fair value is recognized straight-line over the vesting period of the option. Stock equivalent units are fair valued at each balance sheet date and the fair value is spread over the remaining vesting period of the unit.

Business combinations:

The acquisition method of accounting requires that we recognize the assets acquired and liabilities assumed at their acquisition date fair values. Goodwill is measured as the excess of consideration transferred over the acquisition date net fair values of the assets acquired and the liabilities assumed.

The determination of the fair values of certain assets and liabilities are usually based on significant estimates provided by management, such as forecast revenue or profit. In determining the fair value of intangible assets, an income approach is generally used and may incorporate the use of a discounted cash flow method. In applying the discounted cash flow method, the estimated future cash flows and residual values for each intangible asset are discounted to a present value using a discount rate appropriate to the business being acquired. These cash flow projections are based on management’s estimates of economic and market conditions including revenue growth rates, operating margins, capital expenditures and working capital requirements.

Cash equivalents:

Investment securities with maturities of three months or less when purchased are considered to be cash equivalents.

Trade and other accounts receivable:

The Company records trade and other accounts receivable at net realizable value and maintains allowances for customers not making required payments. The Company determines the adequacy of allowances by periodically evaluating each customer receivable considering our customer’s financial condition, credit history and current economic conditions.

The Company is exposed to credit losses primarily through sales of products. The Company’s expected loss allowance methodology for trade and other accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of customers’ receivables. Due to the short-term nature of such receivables, the estimate of accounts receivable amounts that may not be collected is based on aging of the accounts receivable balances and the financial condition of customers.

60

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Additionally, a further allowance is included to account for the Company’s historic track record of credit losses, for balances which are not aged sufficiently to be considered under the aging based approach

.

Inventories:

Inventories are stated at the lower of cost (FIFO method) or market value. Cost includes materials, labor and an appropriate proportion of plant overheads. The Company accrues volume discounts where it is probable that the required volume will be attained and the amount can be reasonably estimated. The discounts are recorded as a reduction in the cost of materials based on projected purchases over the period of the agreement. Inventories are adjusted for estimated obsolescence and written down to market value based on estimates of future demand and market conditions.

Property, plant and equipment:

Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is provided over the estimated useful lives of the assets using the straight-line method and is allocated between cost of goods sold and operating expenses. The cost of additions and improvements are capitalized. Maintenance and repairs are charged to expenses as incurred. When assets are sold or retired the associated cost and accumulated depreciation are removed from the consolidated financial statements and any related gain or loss is included in earnings. The estimated useful lives of the major classes of depreciable assets are as follows:

Buildings	7 to 25 years
Equipment	3 to 10 years

Goodwill:

Goodwill is deemed to have an indefinite life and is subject to at least annual impairment assessments at the reporting unit level. The Company considers that its reporting units are consistent with its reportable segments. The components in each segment (including products, markets and competitors) have similar economic characteristics and the segments, therefore, reflect the lowest level at which operations and cash flows can be sufficiently distinguished, operationally and for financial reporting purposes, from the rest of the Company.

Initially we perform a qualitative assessment to determine whether it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reportable segment is less than the carrying amount prior to performing a quantitative goodwill impairment test. The annual measurement date for impairment assessment of the goodwill relating to the Performance Chemicals, Fuel Specialties and Oilfield Services segments is December 31 each year. Factors utilized in the qualitative assessment process include macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and Company specific events.

If a quantitative test is required, we assess the fair value based on projected

post-tax

cash flows discounted at the Company’s weighted average cost of capital. These fair value techniques require management judgment and estimates including revenue growth rates,

61

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

projected operating margins, changes in working capital and discount rates. We would develop these assumptions by considering recent financial performance and industry growth estimates.

O

ther intangible assets:

Other intangible assets are deemed to have finite lives and are amortized using the straight-line method over their estimated useful lives. The Company capitalizes software development costs as intangible assets, including licenses, subsequent to the establishment of technological feasibility. These assets are tested for potential impairment when events occur or circumstances change, which suggest an impairment may have occurred

.

In order to facilitate testing for potential impairment the Company groups together assets at the lowest possible level for which cash flow information is available. Undiscounted future cash flows expected to result from the asset groups are compared with the carrying value of the assets and, if such cash flows are lower, an impairment loss may be recognized. The amount of the impairment loss is the difference between the fair value and the carrying value of the assets. Fair values are determined using

post-tax

cash flows discounted at the Company’s weighted average cost of capital. If events occur or circumstances change it may cause a reduction in the periods over which the assets are amortized, or result in a

non-cash

impairment of their carrying value. A reduction in the amortization periods would have no impact on cash flows.

The estimated useful lives of the major classes of assets are as follows:

Technology	10 to 17 years
Customer lists	10 to 15 years
Brand names	5 to 10 years
Product rights	9 to 10 years
Internally developed software	3 to 10 years
Marketing related	11 years

Leases:

We determine if an arrangement is a lease at inception. The present value of the future lease payments for operating leases is included in operating lease

right-of-use

(“ROU”) assets, and operating lease liabilities (current and

non-current)

on our consolidated balance sheet at the reporting date. The carrying value of assets under finance leases is included in property, plant and equipment and finance lease liabilities (current and

non-current)

on our consolidated balance sheet at the reporting date.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of future lease payments over the remaining lease term. Very few of our leases have renewal options or early termination break clauses, but where they do we have assessed the term of the lease based on any options being exercised only if they are reasonably certain. As most of our leases do not provide an implicit interest rate, we use our incremental borrowing rate based on the information available at point of recognition in determining the present value of future payments.

62

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The operating lease ROU asset excludes lease incentives and initial direct costs incurred. Lease expense for lease payments is recognized on a straight-line basis over the lease term unless payments are variable per the agreement. We do not separate related

non-lease

components from lease components. Where we have lease payments linked to an index or inflationary rate, this rate has been used to value the asset and liability at the inception of the lease. If the payments are not linked to a specific index or inflationary rate, but can vary during the term of the agreement, they have been included at their actual value for each future period. In some circumstances the future expected payments may be dependent on other factors, for example production volumes, in which case we have used the minimum future expected payments to value the asset.

We do not recognize a ROU asset or operating lease liability for short-term leases (with a length of one year or less), and any associated cost is recognized, as incurred, through the income statement

.

Deferred finance costs:

The costs relating to debt financing are capitalized and amortized using the effective interest method over the expected life of the debt financing facility. The amortization charge is included in interest expense in the income statement.

Impairment of long-lived assets:

The Company reviews the carrying value of its long-lived assets, including buildings and equipment, whenever changes in circumstances suggest that the carrying values may be impaired. In order to facilitate this test the Company groups together assets at the lowest possible level for which cash flow information is available. Undiscounted future cash flows expected to result from the asset groups are compared with the carrying value of the asset groups and if they are lower an impairment loss may be recognized. The amount of the impairment loss is the difference between the fair value and the carrying value of the asset groups. Fair values are determined using

post-tax

cash flows discounted at the Company’s weighted average cost of capital.

Derivative instruments:

From

time to time,the Company uses various derivative instruments including forward currency contracts, options, interest rate swaps and commodity swaps to manage certain exposures. These instruments are entered into under the Company’s corporate risk management policy to minimize exposure and are not for speculative trading purposes. The Company recognizes all derivatives as either current or

non-current

assets or liabilities in the consolidated balance sheet and measures those instruments at fair value. Changes in the fair value of derivatives that are not designated as hedges, or do not meet the requirements for hedge accounting, are recognized in earnings. Derivatives which are designated as hedges are tested for effectiveness on a quarterly basis, and marked to market. The ineffective portion of the derivative’s change in value is recognized in earnings. The effective portion is recognized in other comprehensive income until the hedged item is recognized in

earnings.

Plant closure provisions:

This

includes both environmental compliance and remediation costs. Environmental compliance costs include ongoing maintenance, monitoring and similar costs

6

3

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

and extend to environmental liabilities that result from other-than-normal operation of long-lived assets, for example pollution. Remediation costs relate to asset retirement obligations at our current and former manufacturing sites following retirement of the long-lived assets, linked to their normal operation. We recognize environmental liabilities when they are probable and the costs can be reasonably estimated, and asset retirement obligations when there is an obligation based on a legal requirement

, including those arising from a

Company promise, and the costs can be reasonably estimated. The vast majority of our plant closure provision relates to our Ellesmere Port site in the United Kingdom.

The Company must comply with environmental legislation in the countries in which it operates or has operated in and annually reassesses the program of work required. This includes estimating the credit-adjusted risk free rate and the timing and cost of performing the remediation work. Management receives input from specialists to develop these estimates and assumptions utilizing the latest information available together with experience of recent costs. While we believe our assumptions for the liabilities are reasonable, they are subjective estimates and it is possible that variations in any of the assumptions will result in materially different calculations to the liabilities we have reported. Costs of future obligations are discounted to their present values using the Company’s credit-adjusted risk-free rate.

Pension plans and other post-employment benefits:

The Company recognizes the funded status of defined benefit post-retirement plans on the consolidated balance sheets and changes in the funded status in comprehensive income. The measurement date of the plan’s funded status is the same as the Company’s fiscal

year-end.

The service costs are recognized as employees render the services necessary to earn the post-employment benefits. Prior service costs and credits and actuarial gains and losses are amortized over the average remaining life expectancy of the inactive participants using the corridor method. The insurance contracts are adjusted each reporting period to reflect the estimated fair value of the premium that would be paid for such contracts at that time.

In May 2022, the Trustees of the United Kingdom defined benefit pension plan (“UK Plan”) entered into an agreement with Legal and General Assurance Society Limited to acquire an insurance policy that operates as an investment asset, with the intent of matching the remaining uninsured part of the UK Plan’s future cash outflow arising from the accrued pension liabilities of members. Such an arrangement is commonly termed as a

“buy-in”.

The benefit obligation was not transferred to the insurer, and the Company remains responsible for paying pension benefits. The initial value of the asset associated with this contract was equal to the premium paid to secure the contract and is adjusted each reporting period to reflect the estimated fair value of the premium that would be paid for such a contract at that time. The

buy-in

reduces the UK Plan’s value at risk in relation to key risks associated with improved longevity, inflation and interest rate movements while improving the security to the UK Plan and its members. The Company consequently benefits from the

buy-in

as it reduces the UK Plan’s potential reliance on the Company for future cash funding requirements.

6

4

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Movements in the Projected Benefit Obligation (“PBO”) are dependent on our assumptions in respect of the discount rate, annual member mortality rates, future return on assets and future inflation.

Income taxes:

The Company provides for income taxes by recognizing deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the relevant tax bases of the assets and liabilities. The Company then evaluates the need for a valuation allowance to reduce deferred tax assets to the amount more likely than not to be realized. The effect on deferred taxes of a change in tax rates is recognized in the period that includes the enactment date. The Company recognizes the tax benefit from a tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company recognizes accrued interest and penalties associated with unrecognized tax benefits as part of income taxes in our consolidated statements of income.

Note 3.     Segment Reporting and Geographical Area Data

The Performance Chemicals, Fuel Specialties and Oilfield Services segments operate in markets where we actively seek growth opportunities although their ultimate customers are different. The Octane Additives segment ceased trading and is no longer a reporting segment from July 1, 2020.

Our Performance Chemicals segment provides effective technology-based solutions for our customers’ processes or products focused in the personal care, home care, agrochemical, mining and other industrial markets.

Our Fuel Specialties segment develops, manufactures, blends, markets and supplies a range of specialty chemicals products used as additives to a wide range of fuels.

Our Oilfield Services segment develops and markets chemical solutions for fracturing, drilling, stimulation and completion operations, products for oil and gas production and transport which aid flow assurance and maintain asset integrity.

The Octane Additives business has ceased trading and is no longer a reporting segment from July 1, 2020 as the production of TEL for use in motor gasoline has finished. Legacy costs related to these operations are now being recorded as operating expenses within corporate costs.

In 2022, the Company had a significant customer in the Oilfield Services segment which accounted for $222.2 million (11.3%) of our net group sales.

Note 5.     Restructuring

During 2020, the Company recorded a charge of $21.3 million for the restructuring of its Octane Additives segment in line with the end of the manufacturing and sale of TEL for use in motor gasoline. As a result, the Octane Additives segment ceased trading and is no longer a reporting segment from July 1, 2020. Production of TEL will continue for sales of our AvGas product line, as reported within our Fuel Specialties segment.

The restructuring charge comprised the future committed costs of environmental monitoring of $2.0 million, remediation of facilities of $7.5 million, contract termination costs of $7.2 million, impairment of tangible assets of $2.0 million and costs of redundancy due to the

down-sizing

of the TEL operations of $2.6 million. During the years ended December 31, 2022 and December 31, 2021 the utilization and the unwinding of the discounting was not material.

Net book amount	$	106.5		$	207.5		$	44.8	$	358.8

The Company’s reporting units, the level at which goodwill is tested for impairment, are consistent with the reportable segments: Performance Chemicals, Fuel Specialties and Oilfield Services.

The components in each segment (including products, markets and competitors) have similar economic characteristics and the segments, therefore, reflect the lowest level at which operations and cash flows can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the Company.

The Company assesses goodwill for impairment on at least an annual basis, initially based on a qualitative assessment to determine whether it is more likely than not that the fair value of a segment is less than the carrying amount. If a potential impairment is identified then an impairment test is performed.

The Company performed its annual impairment assessment in respect of goodwill as at December 31, 2022, 2021 and 2020. Our impairment assessment concluded that there had been no impairment of goodwill in respect of those reporting units.

We believe that where appropriate the assumptions used in our impairment assessments are reasonable, but that they are judgmental, and variations in any of the assumptions may result in materially different calculations of any potential impairment charges.

Note 10.     Pension and Post-Employment Benefits

United Kingdom plan

The Company maintains a defined benefit pension plan covering certain current and former employees in the United Kingdom (the “UK Plan”). The UK Plan is closed to future service accrual and has a large number of deferred and current pensioners. The Projected Benefit Obligation (“PBO”) is based on final salary and years of credited service reduced by social security benefits according to a plan formula. Normal retirement age is 65 but provisions are made for early retirement.

In May 2022, the Trustees of the UK Plan entered into an agreement with Legal and General Assurance Society Limited to acquire an insurance policy that operates as an investment asset, with the intent of matching the remaining uninsured part of the UK Plan’s future cash outflow arising from the accrued pension liabilities of members. Such an arrangement is commonly termed as a

“buy-in”.

The benefit obligation was not transferred to the insurer, and the Company remains responsible for paying pension benefits. The initial value of the asset associated with this contract was equal to the premium paid to secure the contract and is adjusted each reporting period to reflect the estimated fair value of the premium that would be paid for such a contract at that time. The

buy-in

reduces the UK Plan’s value at risk in relation to key risks associated with improved longevity, inflation and interest rate movements while

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

improving the security to the UK Plan and its members. The Company consequently benefits from the

buy-in

as it reduces the UK Plan’s potential reliance on the Company for future cash funding requirements.

In 2022, the Company contributed $0.0 million (2021 – $0.0 million) in cash to the UK Plan in accordance w

ith a

n agreement with the trustees. For the year ending December 31, 2023,

there

are no plans to make cash contributions to the UK Plan.

Following the

buy-in,

the UK Plan does not need to follow an investment strategy. The discount rate used represents the annualized yield based on a cash flow matched methodology with reference to an AA corporate bond spot curve and having regard to the duration of the UK Plan’s liabilities.

The inflation rate is derived using a similar cash flow matched methodology as used for the discount rate but having regard to the difference between yields on fixed interest and index linked United Kingdom government

gilts.

Debt securities

In the prior year, fixed income securities are valued based on quotations received from independent pricing services or from dealers who make markets in such securities and are classified as Level 1. Corporate debt securities are classified as Level 2 in line with the industry standard.

Equity backed securities

In the prior year, common and preferred stock for which market prices are readily available at the measurement date are valued at the last reported sale price or official closing price on the primary market or exchange on which they are actively traded. Other financial derivatives are classified as Level 2 and certain investments that are measured at fair value using the net asset value per share (or its equivalent) have not been categorized with a hierarchy.

Other asset backed securities

The Company has invested in insurance contracts, known as

buy-in

contracts. The value of the insurance contracts are based on significant unobservable inputs including plan participant medical data, in addition to observable inputs which include expected return on assets and estimated value premium. Therefore, we have classified the contracts as Level 3 investments. Fair value estimates are provided by external parties and are subsequently reviewed and approved by management.

In 2021 a

non-U.S.

subsidiary, Innospec Limited, entered into a review by the U.K. tax authorities under the U.K.’s Profit Diversion Compliance Facility (“PDCF”) in relation to the period 2017 to 2020 inclusive. The Company determined that additional tax and interest totaling $1.0 million may arise as a result of the ongoing review. During 2022 the Company recorded an additional $0.1 million of tax which was offset by a $0.1 million reduction for foreign exchange movements.

A

non-U.S.

subsidiary, Innospec Performance Chemicals Italia Srl, is subject to an ongoing tax audit in relation to the period 2011 to 2014 inclusive. The Company has determined that additional tax, interest and penalties totaling $3.2 million may arise as a consequence of the tax audit. This includes additional interest accrued of $0.1 million which was offset by

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

$0.2 million foreign exchange movements recorded during 2022. As any additional tax arising as a consequence of the tax audit would be reimbursed by the previous owner under the terms of the sale and purchase agreement, an indemnification asset of the same amount is recorded in the financial statements to reflect this arrangement.

In 2018 the Company recorded an unrecognized tax benefit in relation to a potential adjustment that could arise as a consequence of the Tax Cuts and Jobs Act of 2017 (“Tax Act”), but

for which retrospective adjustment to the filed 2017 U.S. federal income tax returns was not permissible. The Company has determined that additional tax, interest and penalties totaling $9.2 million may arise in relation to this item. This includes a reduction in the unrecognized tax benefit of $2.8 million related to tax adjustments recognized during 2022 that would offset adjustments arising as a consequence of the Tax Act.

The Company and its U.S. subsidiaries remain open to examination by the IRS for certain elements of 2017 year and for years 2019 onwards under the statute of limitations. The Company’s subsidiaries in foreign tax jurisdictions are open to examination including Brazil (2018 onwards), Germany (2018 onwards), and the U.K. (2017 onwards).

Foreign income inclusions arise each year from certain types of income earned overseas being taxable under U.S. tax regulations. Foreign tax credits can fully or partially offset these incremental U.S. taxes from foreign income inclusions. The utilization of foreign tax credits varies year on year as this is dependent on a number of variable factors which are difficult to predict and may prevent offset. The effective tax rate is negatively impacted by the net impact of foreign inclusions post foreign tax credit usage in 2022.

As a consequence of the Company having operations outside of the U.S., it is exposed to foreign currency fluctuations. These have had a negative impact on the effective tax rate in 2022.

In 2022 there was an increase in the level of profits arising in the U.S. compared to prior periods. This has increased the amount of state and local taxes falling due, which has had a negative impact on the effective tax rate, but has also increased the level of foreign-derived intangible income benefit that the Company is entitled to, which has had a positive impact on the effective tax rate in the year.

Other items do not have a significant impact on the effective tax rate.

The Company assesses the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. Available evidence considered in determining the use of deferred tax assets includes, but is not limited to, cumulative losses arising in recent accounting periods, the Company’s estimate of future taxable income and any applicable

tax-planning

strategies. Based on such evidence, if it is more likely than not that some portion or all of such deferred tax assets will not be realized, a valuation allowance is recorded to reduce the Company’s deferred tax assets. On the basis of this evaluation, as of December 31, 2022, a valuation allowance of

8

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

$0.7 million has been recorded to

recognize

only the portion of the deferred tax asset that is more likely than not to be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carry forward period are reduced or increased or if other evidence becomes available.

As of December 31, 2022, the Company has approximately $5.1 million of

tax-effected

U.S. federal net operating loss carryforwards. These loss carryforwards can be carried forward indefinitely without expiration, and the Company expects to utilize the losses in their entirety. The Company has approximately $0.4 million of

tax-effected

state net operating loss carryforwards, net of federal benefit. Some of these loss carryforwards will begin to expire in 2036 if not utilized, while other

s

can be carried forward indefinitely. The Company also has approximately $4.8 million of tax-effected foreign net operating loss carryforwards, net of valuation allowance, across four of the Company’s foreign subsidiaries, which can also be carried forward indefinitely.

Note 12.    Long-Term Debt

As at December 31, 2022, and December 31, 2021, the Company has not drawn down on its revolving credit facility.

The Company continues to have available a $250.0 million revolving credit facility until September 25, 2024. The facility contains an accordion feature whereby the Company may elect to increase the total available borrowings by an aggregate amount of up to $125.0 million.

The deferred finance costs of $0.6 million (December 31, 2021 – $1.0 million) related to the arrangement of the credit facility, are included within other current and

non-current

assets at the balance sheet dates.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The obligations of the Company under the credit facility are secured obligations and guaranteed by certain subsidiaries of the Company. Amounts available under the revolving facility may be borrowed in U.S. dollars, Euros, British pounds and other freely convertible currencies.

The Company’s credit facility contains restrictive clauses which may constrain our activities and limit our operational and financial flexibility. The facility obliges the lenders to comply with a request for utilization of finance unless there is an event of default outstanding. Events of default are defined in the credit facility and include a material adverse change to our assets, operations or financial condition. The facility contains a number of restrictions that limit our ability, amongst other things, and subject to certain limited exceptions, to incur additional indebtedness, pledge our assets as security, guarantee obligations of third parties, make investments, undergo a merger or consolidation, dispose of assets, or materially change our line of business.

In addition, the credit facility contains terms which, if breached, would result in it becoming repayable on demand. It requires, among other matters, compliance with the following financial covenant ratios measured on a quarterly basis: (1) the ratio of net debt to EBITDA shall not be greater than 3.0:1 and (2) the ratio of EBITDA to net interest shall not be less than 4.0:1. Management has determined that the Company has not breached these covenants throughout the period to December 31, 2022 and does not expect to breach these covenants for the next 12 months.

The weighted average rate of interest on borrowings was 0.00% at December 31, 2022 and 0.00% at December 31, 2021. Payments of interest on long-term debt were $0.0 million, $0.0 million and $0.8 million in 2022, 2021 and 2020, respectively.

The net cash outflows in respect of refinancing costs were $0.0 million, $0.0 million and $0.3 million in 2022, 2021 and 2020, respectively.

Note 13.    Plant Closure Provisions

The Company has continuing plans to remediate manufacturing facilities at sites around the world as and when those operations are expected to cease or we are required to decommission the sites according to local laws and regulations. The liability for estimated plant closure costs includes costs for environmental remediation liabilities and asset retirement obligations.

The principal site giving rise to asset retirement obligations is the manufacturing site at Ellesmere Port in the United Kingdom. There are also asset retirement obligations and environmental remediation liabilities on a much smaller scale in respect of other manufacturing sites.

Movements in the provisions are summarized as follows:

(in millions)	2022			2021			2020

Due within one year		(5.3	)		(5.2	)		(6.6	)
Due after one year	$	51.9		$	51.3		$	51.9

Amounts due within one year refer to provisions where expenditure is expected to arise within one year of the balance sheet date.

The charge for the period in 2022 represents the accretion expense recognized of $3.8 million and a further $1.5 million primarily in respect of changes in the expected cost and scope of future remediation activities. The charges for plant closure provisions are recognized in cost of goods sold for our reporting segments and within selling, general and administrative expenses for Corporate costs.

The Octane Additives segment ceased trading and is no longer a reporting segment from July 1, 2020. As a result, there was a

one-off

charge in 2020 of $7.5 million for the restructuring activities related to the legacy production of TEL for use in motor gasoline.

We recognize environmental remediation liabilities when they are probable and the costs can be reasonably estimated, and asset retirement obligations when there is an obligation based on a legal requirement, including those arising from a Company promise, and the costs can be reasonably estimated. The Company has to anticipate the program of work required and the associated future expected costs, and comply with environmental legislation in the countries in which it operates or has operated in.

Expenditure utilizing plant closure provisions was $4.2 million, $5.3 million and $4.1 million in 2022, 2021 and 2020, respectively.

Note 14.    Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The Company utilizes a

mid-market

pricing convention for valuing the majority of its assets and liabilities measured and reported at fair value. The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These

8

7

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

inputs can be readily observable, market corroborated or generally unobservable. The Company primarily applies the market approach for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Company is able to classify fair value balances based on the observability of those inputs. The Company gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy Levels. In 2019, the Company evaluated the fair value hierarchy levels assigned to its assets and liabilities, and concluded that there should be no transfers into or out of Levels 1, 2 and 3.

The following table presents the carrying amount and fair values of the Company’s assets and liabilities measured on a recurring basis:

	December 31, 2022				December 31, 2021
(in millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Assets
Non-derivatives:
Cash and cash equivalents	$	147.1	$	147.1	$	141.8	$	141.8

Non-financial liabilities (Level 3 measurement):
Stock equivalent units		26.4		26.4		17.3		17.3

The following methods and assumptions were used to estimate the fair values:

Cash and cash equivalents:

The carrying amount approximates fair value because of the short-term maturities of such instruments.

8

8

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Emissions Trading Scheme credits:

The fair value is determined by the open market pricing at the end of the reporting period.

Long-term debt:

Long-term debt principally comprises the revolving credit facility, which is shown net of deferred finance costs that have been capitalized. The fair value of long-term debt approximates to the carrying value.

Derivatives:

The fair value of derivatives relating to foreign currency forward exchange contracts and interest rate swaps are derived from current settlement prices and comparable contracts using current assumptions. Foreign currency forward exchange contracts primarily relate to contracts entered into to hedge future known transactions or hedge balance sheet net cash positions. The movements in the carrying amounts and fair values of these contracts are largely due to changes in exchange rates against the U.S. dollar. Interest rate swaps in the prior year related to contracts taken out to hedge interest rate risk on a portion of our long-term debt.

Stock equivalent units:

The fair values of stock equivalent units are calculated at each balance sheet date using either the Black-Scholes or Monte Carlo method.

Note 15.    Derivative Instruments and Risk Management

The Company has limited involvement with derivative instruments and does not trade them. The Company does use derivatives to manage certain interest rate, foreign currency exchange rate, raw material cost exposures and greenhouse gases emission allowances, as the need arises.

The Company previously entered into interest rate swap contracts to reduce interest rate risk on its core debt. As at December 31, 2022 and at December 31, 2021, there were no interest rate swaps in place. Interest rate swaps were previously in place to hedge interest rate risk on the term loan for a notional value that matched the repayment profile of the term loan.

The Company enters into various foreign currency forward exchange contracts to minimize currency exchange rate exposure from expected future cash flows. As at December 31, 2022, foreign currency forward exchange contracts with a notional value of $161.1 million were in place (December 31, 2021 $113.0 million), with maturity dates of up to one year from the date of inception. These foreign currency forward exchange contracts have not been designated as hedging instruments, and their impact on the income statement for 2022 was a gain of $0.7 million (2021 – gain $1.0 million).

As at December 31, 2022 and December 31, 2021 the Company did not hold any raw material derivatives.

The Company participates in the new United Kingdom Emissions Trading Scheme (“UK ETS”) which was launched on January 1, 2021. Emissions trading schemes work on the ‘cap and trade’ principle, where a cap is set on the total amount of certain greenhouse gases that

8

9

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

can be emitted by sectors covered by the scheme. This limits the total amount of carbon that can be emitted. Within this cap, participants receive free allowances and/or buy emission allowances at auction or on the secondary market which they can trade with other participants as needed. As at December 31, 2022, the Company held UK ETS credits of $2.7 million (December 31, 2021 – $3.9 million).

The Company sells a range of specialty chemicals to major oil refiners and chemical companies throughout the world. Credit limits, ongoing credit evaluation and account monitoring procedures are intended to minimize bad debt risk. Collateral is not generally required.

Note 16.    Commitments and Contingencies

Environmental remediation liabilities and asset retirement obligations

Commitments in respect of environmental remediation liabilities and asset retirement obligations are disclosed in Note 13 of the Notes to the Consolidated Financial Statements.

Capital commitments

The estimated additional cost to complete work in progress at December 31, 2022 is $37.7 million (2021 – $23.5 million).

Internally developed software

The estimated additional cost to complete work in progress at December 31, 2022 is $25.0 million (2021 – $0.0 million).

Contingencies

Legal matters

While we are involved from time to time in claims and legal proceedings that result from, and are incidental to, the conduct of our business including business and commercial litigation, employee and product liability claims, there are no material pending legal proceedings to which the Company or any of its subsidiaries is a party, or of which any of their property is subject. It is possible however, that an adverse resolution of an unexpectedly large number of such individual items could in the aggregate have a material adverse effect on results of operations for a particular year or quarter.

Guarantees

The Company and certain of the Company’s consolidated subsidiaries are contingently liable for certain obligations of affiliated companies primarily in the form of guarantees of debt and performance under contracts entered into as a normal business practice. This

includes

90

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

guarantees

of

non-U.S.

excise taxes and customs duties. As at December 31, 2022, such guarantees which are not recognized as liabilities in the consolidated financial statements amounted to $7.0 million (December 31, 2021 – $4.6 million). The remaining terms of the fixed maturity guarantees vary from approximately 1 month to 4 years, with some further guarantees having no fixed expiry date.

Under

the terms of the guarantee arrangements, generally the Company would be required to perform should the affiliated company fail to fulfill its obligations under the arrangements. In some cases, the guarantee arrangements have recourse provisions that would enable the Company to recover any payments made under the terms of the guarantees from securities held of the guaranteed parties’ assets.

The Company and its affiliates have numerous long-term sales and purchase commitments in their various business activities, which are expected to be fulfilled with no adverse consequences material to the Company.

At December 31, 2022, the Company had authorized common stock of 40,000,000 shares (2021 - 40,000,000).

Note 18.    Share-Based Compensation Plans

Stock option plans

The Company has two stock option plans, the Omnibus Long-Term Incentive Plan and the ShareSave Plan 2008 under which it currently grants awards. The stock options have vesting periods ranging from 2 to 5 years and in all cases stock options granted expire within 10 years of the date of grant. All grants are at the sole discretion of the Compensation Committee of the Board of Directors. Grants may be priced at market value or at a premium or discount. The aggregate number of shares of common stock reserved for issuance which can be granted under the plans is 2,550,000.

In the fourth quarter of 2020, a number of stock options that were granted to 14 employees in February 2018 were modified to extend the vesting period by two years. The incremental compensation cost resulting from the modifications was $2.4 million, resulting from the performance targets that were not achieved in 2020 being extended to a future

period.

91

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The fair value of stock options is measured on the grant date using either the Black-Scholes model, or in cases where performance criteria are dependent upon external factors such as the Company’s stock price, using a Monte Carlo model.

The Company’s policy is to issue shares from treasury stock to holders of stock options who exercise those options, but if sufficient treasury stock is not available, the Company will issue previously unissued shares of stock to holders of stock options who exercise options.

Stock equivalent units

The Company awards Stock Equivalent Units (“SEUs”) from time to time as a long-term performance incentive. SEUs are cash settled equity instruments conditional on certain performance criteria and the fair value is linked to the Innospec Inc. share price. SEUs have vesting periods ranging from six months to 5 years and in all cases SEUs granted expire within 10 years of the date of grant. Grants may be priced at market value or at a premium or discount. There is no limit to the number of SEUs that can be granted. As at December 31, 2022 the liability for SEUs of $26.4 million is included in accrued liabilities in the consolidated balance

sheet, where they will remain

until they are cash settled.

In the fourth quarter of 2020, a number of SEUs that were granted to 61 employees in February 2018 were modified to extend the vesting period by two years. The adjusted compensation cost resulting from the modifications has been recognised by the fair valuation at the balance sheet date based on the extended vesting period.

The fair value of SEUs is

re-measured

at each balance sheet reporting date using either the Black-Scholes model, or in cases where performance criteria are dependent upon external factors such as the Company’s stock price, using a Monte Carlo model.

Compensation cost

The compensation cost recorded for stock options was $6.7 million, $4.4 million and $5.8 million for 2022, 2021 and 2020, respectively. The compensation cost for stock options is based on the grant-date fair value and spread evenly over the vesting period.

The compensation cost recorded for SEUs was $24.2 million, $3.1 million and $1.9 million for 2022, 2021 and 2020, respectively. The compensation cost for SEUs is spread over the life of the award subject to a revaluation to the fair value at each quarter end. The revaluation may result in a charge or a credit to the income statement in each quarter dependent upon our share price movements and other performance criteria.

Forfeits are accounted for as an adjustment to the charge in the period in which the forfeits occur.

92

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Transactions in the period

The fair value of each stock option or SEU granted in the year was estimated on the date of grant using the Black-Scholes option-pricing model and where appropriate the Monte Carlo simulation model. These models utilized the following weighted average assumptions to determine the grant-date fair values of the share-based compensation granted in the year:

	2022			2021			2020
Dividend yield		1.27	%		1.17	%		1.15	%
Expected life		5 years			5 years			5 years
Volatility		39.8	%		40.2	%		27.4	%
Risk free interest rate		2.90	%		0.45	%		1.10	%

The dividend yield was based on our recent history of dividend payouts. The expected life was determined based upon historical exercise experience. The volatility was determined based upon the

historical

daily stock price volatilities. The risk free interest rate was based on the U.S. Federal Reserve 3 year interest rate at the grant dates, which approximates to the expected term of the options.

The following tables summarizes the transactions of the Company’s share-based compensation plans for the year ended December 31, 2022.

	Number of shares			Weighted Average Grant-Date Fair Value
Nonvested at December 31, 2021		680,711		$	74.6

Other disclosures

As at December 31, 2022, there was $

23.1

 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of

1.9

years.

The total intrinsic value of share-based compensation plans outstanding at December 31, 2022 was $71.5 million. The total intrinsic value of share-based compensation plans exercisable at December 31, 2022 was $9.7 million. The total intrinsic value of share-based compensation plans exercised for the year ended December 31, 2022 was approximately $18.1 million.

The total cash paid for SEUs exercised for the year ended December 31, 2022 was approximately $15.0 million.

The total fair value of share-based compensation that vested for the year ended December 31, 2022 was $13.0 million.

The weighted-average grant-date fair value of share-based compensation plans granted during 2022, 2021, and 2020 was $60.2, $84.8, and $72.4, respectively.

The Company recorded a current tax charge of $0.7 million in 2022, and a current tax benefit of $1.3 million and $1.6 million in 2021 and 2020, respectively, in relation to stock option compensation. This amount is inclusive of excess tax benefits.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Note 20.    Recently Issued Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board issued Accounting Standards Update (ASU)

No. 2019-12,

Simplifying the Accounting for Income Taxes (Topic 740). This guidance removes certain exceptions to the general principles in Topic 740 and improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Adopting the new standard on January 1, 2021 has not impacted the Company’s prior period comparatives and has not had a material impact on the Company’s consolidated financial statements, including its accounting policies, processes and systems.

In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”)

No. 2020-04,

Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848). This provides various practical expedients to account for contract modification for loan agreements, lease agreements and derivative instruments currently referencing the London Interbank Offered Rate (“LIBOR”) up to December 31, 2022. In March 2021, the FCA announced that the intended cessation date of the overnight

1-,

3-,

6-,

and

12-month

tenors of USD LIBOR would be June 30, 2023, which is beyond the current sunset date of Topic 848. In December 2022, the Financial Accounting Standards Board issued ASU

No. 2022-06,

Deferral of Sunset Date of Topic 848. This extends the use of practical expedients from December 31, 2022 to December 31, 2024 to cover the period where significant modification may take place. To date, we have not required the use of expedients covered by this topic, but we will continue to assess the need for their use through to the revised sunset date. We do not expect there to be a material impact on the Company’s results.

Item 9 Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on an evaluation carried out as of the end of the period covered by this report, under the supervision and with the participation of our management, our Chief Executive Officer and our Chief Financial Officer concluded that the Company’s “disclosure controls and procedures” (as defined in Rules

13a-15(e)

and

15d-15(e)

of the Securities Exchange Act of 1934) were effective as of December 31, 2022.

Management’s Report on Internal Control Over Financial Reporting

Our management, including the Chief Executive Officer and the Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting (within the meaning of Rule

13a-15(f)

under the Securities Exchange Act of 1934). The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Internal control over financial reporting includes those policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America and that our receipts and expenditures are being made only in accordance with authorization of our management and directors; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the consolidated financial statements.

Due to its inherent limitations, management does not believe that internal control over financial reporting will prevent or detect all errors or fraud. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on criteria in

Internal Control – Integrated Framework (2013)

 issued by the Committee of Sponsoring Organizations of the Treadway Commission the evaluation of our management,

98

including the Chief Executive Officer and the Chief Financial Officer, concluded that the Company did maintain effective internal control over financial reporting as of December 31, 2022.

Our independent registered public accounting firm PricewaterhouseCoopers LLP, has audited our Consolidated Financial Statements and the effectiveness of our internal control over financial reporting as of December 31, 2022. Their report is included in Item 8 of this Annual Report on Form

10-K.

Changes in Internal Controls over Financial Reporting

The Company is continuously seeking to improve the efficiency and effectiveness of its operations and of its internal controls. This is intended to result in refinements to processes throughout the Company.

There were no changes to our internal control over financial reporting which were identified in connection with the evaluation required by paragraph (d) of Rules

13a-15

and

15d-15

under the Securities Exchange Act of 1934, have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Item 9B Other Information
