General Innospec develops, manufactures, blends, markets and supplies specialty chemicals for use as fuel additives, ingredients for personalcare, home care, agrochemical, mining and other applications and oilfield chemicals. Our products are sold primarily to oil and gasexploration and production companies, oil refiners, fuel manufacturers and users, formulators of personal care, home care,agrochemical and mining formulations, and other chemical and industrial companies throughout the world. Our fuel additives helpimprove 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 moreenvironmentally friendly. Our performance chemicals provide effective technology-based solutions for our customers’ processes orproducts focused in the Personal Care, Home Care, Agrochemical and Mining markets. Our Octane Additives business manufacturesa fuel additive for use in automotive gasoline. Segment Information The Company reports its financial performance based on the four reportable segments described as follows: • Fuel Specialties • Performance Chemicals • Oilfield Services • Octane Additives The Fuel Specialties, Performance Chemicals and Oilfield Services segments operate in markets where we actively seek growthopportunities although their ultimate customers are different. The Octane Additives segment is expected to decline in the near futureas our one remaining refinery customer transitions to unleaded fuel. For financial information about each of our segments, see Note 3 of the Notes to the Consolidated Financial Statements. Fuel Specialties Our Fuel Specialties segment develops, manufactures, blends, markets and supplies a range of specialty chemical products used asadditives to a wide range of fuels. These fuel additive 3Table of Contentsproducts help improve fuel efficiency, boost engine performance and reduce harmful emissions; and are used in the efficientoperation of automotive, marine and aviation engines, power station generators, and heating oil. The segment has grown organically through our development of new products to address what we believe are the key drivers indemand for fuel additives. These drivers include increased demand for fuel, focus on fuel economy, changing engine technology andlegislative developments. We have also devoted substantial resources towards the development of new and improved products thatmay be used to improve combustion efficiency. Our customers in this segment include national oil companies, multinational oil companies and fuel retailers. Performance Chemicals Our Performance Chemicals segment provides effective technology-based solutions for our customers’ processes or products focusedin the Personal Care, Home Care, Agrochemical and Mining markets. This segment has grown through acquisitions and the development and marketing of innovative products. The focus for ourPerformance Chemicals segment is to develop high performance products from its technology base in a number of targeted markets. Our customers in this segment include large multinational companies, manufacturers of personal care and household products andspecialty chemical manufacturers operating in agrochemical, mining and other industrial applications. Oilfield Services Our Oilfield Services segment develops and markets products to prevent loss of mud in drilling operations, chemical solutions forfracturing, stimulation and completion operations and products for oil and gas production which aid flow assurance and maintainasset integrity. This segment has recently been growing strongly, driven by increased customer activity, following the increase in crude oil prices, asthe industry recovers from the significant declines of the last two years. Our customers in this segment include multinational public and independent companies operating currently principally in theAmericas. Octane Additives Our Octane Additives segment, which we believe is the world’s only producer of tetra ethyl lead (“TEL”), comprises sales of TELfor use in automotive gasoline and provides services in respect of environmental remediation. We are continuing to responsiblymanage the decline in the demand for TEL for use in automotive gasoline in line with the transition plans to 4Table of Contentsunleaded gasoline for our one remaining refinery customer. Cost improvement measures continue to be taken to respond to decliningmarket demand. Sales of TEL for use in automotive gasoline are principally made to state-owned refineries located in North Africa. Ourenvironmental remediation business manages the cleanup of redundant TEL facilities as refineries complete the transition tounleaded gasoline. Strategy Our strategy is to develop new and improved products and technologies to continue to strengthen and increase our market positionswithin our Fuel Specialties, Performance Chemicals and Oilfield Services segments. We also actively continue to assess potentialstrategic acquisitions, partnerships and other opportunities that would enhance and expand our customer offering. We focus onopportunities that would extend our technology base, geographical coverage or product portfolio. We believe that focusing on theFuel Specialties, Performance Chemicals and Oilfield Services segments, in which the Company has existing experience, expertiseand knowledge, provides opportunities for positive returns on investment with reduced operating risk. We also continue to developour 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 ConsolidatedFinancial Statements. Working Capital The nature of our customers’ businesses generally requires us to hold appropriate amounts of inventory in order to be able to respondquickly to customers’ needs. We therefore require corresponding amounts of working capital for normal operations. We do notbelieve that this is materially different to what our competitors do, with the exception of cetane number improvers, in which case wemaintain high enough levels of inventory, as required, to retain our position as market leader in sales of these products. The purchase of large amounts of certain raw materials across all our segments can create some variations in working capitalrequirements, 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 areadequate for our current operations. Our major purchases are cetane number improvers, ethylene, various solvents and lubricityimprovers. 5Table of ContentsThese purchases account for a substantial portion of the Company’s variable manufacturing costs. These materials are, with theexception of ethylene for our operations in Germany, readily 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 ourGerman operations via a direct pipeline from a neighboring site, making it effectively a single source. Ethylene is used as a primaryraw material for our German operations in products representing approximately 4% of Innospec’s sales. We use long-term contracts (generally with fixed or formula-based costs) and advance bulk purchases to help ensure availability andcontinuity of supply, and to manage the risk of cost increases. From time to time, for some raw materials, the risk of cost increases ismanaged with commodity swaps. We continue to monitor the situation and adjust our procurement strategies as we deem appropriate. The Company forecasts its rawmaterial requirements substantially in advance, and seeks to build long-term relationships and contractual positions with supplypartners to safeguard its raw material positions. In addition, the Company operates an extensive risk management program whichseeks 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 competitiveadvantage, particularly in the Fuel Specialties and Performance Chemicals segments. The Company does not, however, consider itsbusiness 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 processesin several jurisdictions. The majority of these patents were developed by the Company and, subject to maintenance obligationsincluding 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 Servicesfor the Purposes of the Registration of Marks” are registered in all jurisdictions in which the Company has a significant marketpresence. The Company also has trademark registrations for certain product names in all jurisdictions in which it has a significantmarket presence. We actively protect our inventions, new technologies, and product developments by filing patent applications and maintaining tradesecrets. In addition, we vigorously participate in patent opposition proceedings around the world where necessary to secure atechnology base free from infringement of our intellectual property. We have sales contracts with customers in some markets using fixed or formula-based prices, as appropriate, to maintain our grossprofits. 6Table of ContentsCompetition Certain markets in which the Company operates are subject to significant competition. The Company competes on the basis of anumber of factors including, but not limited to, product quality and performance, specialized product lines, customer relationshipsand service, and regulatory expertize. Fuel Specialties: Within the Fuel Specialties segment, the Fuels sub-market is generally characterized by a small number ofcompetitors, none of which hold a dominant position. We consider our competitive edge to be our proven technical developmentcapacity, independence from major oil companies and strong long-term customer relationships. Performance Chemicals: Within the Performance Chemicals segment we operate in the Personal Care, Home Care, Agrochemicaland Mining markets which are highly fragmented, and the Company experiences substantial competition from a large number ofmultinational and specialty chemical suppliers in each geographical market. Our competitive position in these markets is based on ussupplying a superior, diverse product portfolio which solves particular customer problems or enhances the performance of new orexisting products. In a number of specialty chemicals markets, we also supply niche product lines, where we enjoy market-leadingpositions. 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 proventechnology, broad regional coverage and strong customer relationships. Octane Additives: We believe our Octane Additives segment is the world’s only producer of TEL and accordingly is the onlysupplier of TEL for use in automotive gasoline. The segment therefore competes with marketers of products and processes thatprovide alternative ways of enhancing octane performance in automotive gasoline. Research, Development, Testing and Technical Support Research, product/application development and technical support (“R&D”) provide the basis for the growth of our Fuel Specialties,Performance Chemicals and Oilfield Services segments. Accordingly, the Company’s R&D activity has been, and will continue tobe, focused on the development of new products and formulations. Our R&D department provides technical support for all of ourreporting segments. Expenditures to support R&D services were $31.4 million, $25.4 million and $25.3 million in 2017, 2016 and2015, respectively. We believe that our proven technical capabilities provide us with a significant competitive advantage. In the last five years, the FuelSpecialties segment has developed new detergent, cold flow improvers, stabilizers, lubricity and combustion improver products, inaddition to the introduction of many new cost effective fuel additive packages. This proven technical capability has also beeninstrumental in enabling us to produce innovative products including Iselux and Statsafe . 7™ ® Table of ContentsHealth, Safety and Environmental Matters We are subject to environmental laws in the countries in which we operate and conduct business. Management believes that theCompany is in material compliance with applicable environmental laws and has made the necessary provisions for the continuedcosts of compliance with environmental laws, including where appropriate asset retirement obligations. Our principal site giving rise to environmental remediation liabilities is the Octane Additives manufacturing site at Ellesmere Port inthe United Kingdom. There are also environmental remediation liabilities on a much smaller scale in respect of our othermanufacturing sites in the U.S. and Europe. At Ellesmere Port there is a continuing asset retirement program related to certainmanufacturing units that have been closed. We recognize environmental remediation liabilities when they are probable and costs can be reasonably estimated, and assetretirement obligations when there is a legal obligation and costs can be reasonably estimated. This involves anticipating the programof work and the associated future expected costs, and so involves the exercise of judgment by management. We regularly review thefuture expected costs of remediation and the current estimate is reflected in Note 12 of the Notes to the Consolidated FinancialStatements. The European Union legislation known as the Registration, Evaluation and Authorization of Chemical Substances Regulations(“REACH”) requires most of the Company’s products to be registered with the European Chemicals Agency. Under this legislationthe Company has to demonstrate that its products are appropriate for their intended purposes. During this registration process, theCompany incurs expense to test and register its products. The Company estimates that the cost of complying with REACH will beapproximately $2 million over the next three years based on the current regulatory environment. Employees The Company had approximately 1900 employees in 24 countries as at December 31, 2017. Available Information Our corporate web site is www.innospecinc.com.

The Company uses thisweb site as a means of disclosing material, non-public information and for complying with its disclosure obligations under SECRegulation FD (“Fair Disclosure”). Accordingly, investors should monitor the Investor Relations portion of the Company’s web site,in addition to following the Company’s press releases, SEC filings, public conference calls, presentations and webcasts. 8Table of ContentsItem 1ARisk Factors The factors described below represent the principal risks associated with our business. Trends in oil and gas prices affect the level of exploration, development and production activity of our customers, and the demandfor 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 corresponding capital spending by, oil and gas companies. The level of exploration,development and production activity is directly affected by trends in oil and gas prices, which historically have been volatile and arelikely to continue to be volatile. Prices for oil and gas are subject to large fluctuations in response to relatively minor changes in thesupply of and demand for oil and gas, market uncertainty, and a variety of other economic and political factors that are beyond ourcontrol. Even the perception of longer-term lower oil and gas prices by oil and gas companies can similarly reduce or defer majorexpenditures given the long-term nature of many large-scale development projects. Factors affecting the prices of oil and gas includethe level of supply and demand for oil and gas, governmental regulations, including the policies of governments regarding theexploration for and production and development of their oil and gas reserves, weather conditions and natural disasters, worldwidepolitical, military, and economic conditions, the level of oil and gas production by non-OPEC countries and the available excessproduction capacity within OPEC, the cost of producing and delivering oil and gas and potential acceleration of the development ofalternative fuels and engine technologies. Any prolonged reduction in oil and gas prices will depress the immediate levels ofexploration, development, and production activity which could have a material adverse impact on our results of operations, financialposition and cash flows. 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, NorthernAfrica, Asia-Pacific, Eastern Europe and South American regions. Our international operations are subject to numerous internationalbusiness risks including, but not limited to, geopolitical and economic conditions, risk of expropriation, import and exportrestrictions, exchange controls, national and regional labor strikes, high or unexpected taxes, government royalties and restrictions onrepatriation of earnings or proceeds from liquidated assets of overseas subsidiaries. Any of these could have a material adverseimpact on our results of operations, financial position and cash flows. We are subject to extensive regulation of our international operations that could adversely affect our business and results ofoperations. Due to our global operations, we are subject to many laws governing international commercial activity, conduct and relations,including those that prohibit improper payments to government officials, restrict where and with whom we can do business, and limitthe products, software 9Table of Contentsand technology that we can supply to certain countries and customers. These laws include but are not limited to, the U.S. ForeignCorrupt Practices Act and United Kingdom Bribery Act, sanctions and assets control programs administered by the U.S. Departmentof 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. Violationsof any of these laws or regulations, which are often complex in their application, may result in criminal or civil penalties that couldhave a material adverse effect 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 intoour 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 existingbusiness. The success of these transactions depends on our ability to efficiently complete transactions, integrate assets and personnelacquired 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 timecommitments, and our failure to manage these as intended could result in unanticipated expenses and losses. Post-acquisitionintegration may result in unforeseen difficulties and may deplete significant financial and management resources that couldotherwise be available for the ongoing development or expansion of existing operations. Furthermore, we may not realize thebenefits of an acquisition in the way we anticipated when we first entered the transaction. Any of these risks could adversely impactour results of operations, financial position and cash flows. 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. Asa result, competitors may be better able to adapt to changes in conditions in our industries, fluctuations in the costs of raw materialsor changes in global economic conditions. Competitors may also be able to introduce new products with enhanced features that maycause a decline in the demand and sales of our products. Consolidation of customers or competitors, or economic problems ofcustomers in our markets could cause a loss of market share for our products, place downward pressure on prices, result in paymentdelays or non-payment, or declining plant utilization rates. These risks could adversely impact our results of operations, financialposition and cash flows. Political developments may adversely affect our business On June 23, 2016, the United Kingdom (U.K.) held a referendum in which voters approved an exit from the European Union (E.U.),commonly referred to as “Brexit”. Subsequently, the U.K. parliament passed the European Union (Notification of Withdrawal) Act2017, which conferred power on the U.K. government to give notice to the European Council, under 10Table of ContentsArticle 50(2) of the Treaty on European Union, of the U.K.’s intention to withdraw from the European Union. The U.K. submittedthis notice to the European Council on March 29, 2017. Accordingly, the U.K. is currently expected to withdraw from the EuropeanUnion on March 29, 2019. The U.K. is currently in the process of negotiating a withdrawal agreement with the European Union, butif this is not agreed and ratified by March 29, 2019 (or such later date as may be agreed between the U.K. and the EuropeanCouncil), the U.K. may be required to withdraw from the European Union without a withdrawal agreement being in force. It ispossible that there will be greater restrictions on imports and exports between the U.K. and E.U. countries and increased regulatorycomplexities. The announcement of Brexit caused significant volatility in global stock markets and currency exchange ratefluctuations that resulted in the strengthening of the U.S. dollar against foreign currencies in which we conduct business. These political developments may adversely impact 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 changingcustomer requirements, and successfully anticipate or respond to technological changes in a cost effective and timely manner willlikely impact our future business success. We compete on a number of fronts including, but not limited to, product quality andperformance. 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 hybridvehicles, and the subsequent impact on the demand for gasoline and diesel. Our inability to maintain a technological edge, innovateand improve our products could cause a decline in the demand and sales of our products, and adversely impact our results ofoperations, financial position and cash flows. Decline in our TEL business The remaining sales of the Octane Additives business are now concentrated to one remaining refinery customer. When this customerchooses to cease using TEL as an octane enhancer then the Company’s future operating income and cash flows from operatingactivities will be materially impacted. The sales of the AvTel product line are recorded within our Fuel Specialties business. The piston aviation industry has been, and iscurrently, researching a safe replacement fuel to replace leaded fuel. While we expect that at some point in the future a replacementfuel will be identified, trialed and supplied to the industry there is no current known replacement. In addition there is no cleartimescale on the legislation of a replacement product. If a suitable product is identified and the use of leaded fuel is prohibited inpiston aviation the Company’s future operating income and cash flows from operating activities would be adversely impacted. 11Table of ContentsHaving a small number of significant customers may have a material adverse impact on our results of operations. Our principal customers are oil and gas exploration and production companies, oil refineries, personal care companies, and otherchemical and industrial companies. These industries are characterized by a concentration of a few large participants. The loss of asignificant customer, a material reduction in demand by a significant customer or termination or non-renewal of a significantcustomer contract could adversely impact 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 cashflows. Movements in the underlying plan asset value and Projected Benefit Obligation (“PBO”) of our United Kingdom defined benefitpension plan are dependent on actual return on investments as well as our assumptions in respect of the discount rate, annual membermortality rates, future return on assets and future inflation. A change in any one of these assumptions could impact the plan assetvalue, PBO and pension credit recognized in the income statement. If future plan investment returns prove insufficient to meet futureobligations, or should future obligations increase due to actuarial factors or changes in pension legislation, then we may be requiredto make additional cash contributions. These events could adversely impact our results of operations, financial position and cashflows. Our success depends on our management team and other key personnel, the loss of any of whom could disrupt our businessoperations. Our future success will depend in substantial part on the continued services of our senior management. The loss of the services ofone or more of our key executive personnel could affect implementation of our business plan and result in reduced profitability. Ourfuture success also depends on the continued ability to attract, develop, retain and motivate highly-qualified technical, sales andsupport staff. We cannot guarantee that we will be able to retain our key personnel or attract or retain qualified personnel in thefuture. If we are unsuccessful in our efforts in this regard, this could adversely impact our results of operations, financial position andcash flows. Continuing adverse global economic conditions could materially affect our current and future businesses. The ongoing concern about the stability of global markets generally and the strength of counterparties in particular has led manylenders and institutional investors to reduce, or cease to provide, credit to businesses and consumers. These factors have led to asubstantial and continuing decrease in spending by businesses and consumers, and a corresponding decrease in global infrastructurespending which could affect our business. Global economic factors affecting our business include, but are not limited to, geopoliticalinstability in some markets, miles driven by passenger and commercial vehicles, legislation to control fuel quality, impact 12Table of Contentsof alternative propulsion systems, consumer demand for premium personal care and cosmetic products, and oil and gas drilling andproduction rates. The availability, cost and terms of credit have been, and may continue to be, adversely affected by the foregoingfactors and these circumstances have produced, and may in the future result in, illiquid markets and wider credit spreads, which maymake it difficult or more expensive for us to obtain credit. Continuing uncertainties in the U.S. and international markets andeconomies leading to a decline in business and consumer spending could adversely impact our results of operations, financialposition 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 have, from time to time,experienced threats to our data and systems. Although we have implemented administrative and technical controls and takeprotective actions to reduce the risk of cyber incidents and protect our information technology, and we endeavor to modify suchprocedures as circumstances warrant, such measures may be insufficient to prevent physical and electronic break-ins, cyber-attacksor other security breaches to our computer systems. While to date we have not experienced a material cyber security breach, oursystems, processes, software and network still may be vulnerable to internal or external security breaches, computer viruses, malwareor other malicious code or cyber-attack, catastrophic events, power interruptions, hardware failures, fire, natural disasters, humanerror, system failures and disruptions, and other events that could have security consequences. Such an information technologyfailure or disruption could prevent us from being able to process transactions with our customers, operate our manufacturingfacilities, and properly report those transactions in a timely manner. A significant, protracted information technology system failuremay result in a material adverse effect on 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. and other jurisdictions. Tax laws are dynamic and subject to change as new lawsare passed and new interpretations of the law are issued or applied. Recently, the U.S. has enacted significant tax reform which willimpact our tax liabilities. Significant judgment is required in estimating our worldwide provision for income taxes. In the ordinarycourse of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Although webelieve our tax estimates are reasonable, any final determination pursuant to tax audits and any related litigation could be materiallydifferent to what is reflected in our consolidated financial statements. Should any tax authority disagree with our estimates anddetermine any additional tax liabilities, including interest and penalties for us, this could adversely impact our results of operations,financial position and cash flows. 13Table of ContentsUncertainty in the interpretation and application of the 2017 Tax Cuts and Jobs Act could materially affect our tax obligationsand effective tax rate The 2017 Tax Cuts and Jobs Act (the “Tax Reform Act”) was enacted on December 22, 2017, and significantly affected U.S. tax lawby changing how the U.S. imposes income tax on multinational corporations. The U.S. Department of Treasury has authority to issueregulations and interpretative guidance that may impact how we apply the law and impact our results of operations in the periodissued and subsequently. The Tax Reform Act requires complex computations not previously required under U.S. tax law. As such, the application ofaccounting guidance for such items is currently uncertain. Further, compliance with the Tax Reform Act and the accounting for suchprovisions requires the accumulation of information not previously required or regularly produced. As a result, we have provided aprovisional estimate of the effect of the Tax Reform Act in our financial statements. As additional regulatory guidance is issued, aswe perform additional analysis on the application of the law, and as we refine our estimates in calculating the effect, our finalanalysis may be different from our current provisional amounts, which could adversely impact our results of operations, financialposition and cash flows. 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, thefinancial position and results of operations of some of our overseas subsidiaries are reported in the relevant local currency and thentranslated 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 cashflows. The primary exchange rate fluctuation exposures we have are with the European Union euro, British pound sterling and Brazilianreal. Exchange rates between these currencies and the U.S. dollar have fluctuated in recent years and may continue to do so. Wecannot accurately predict future exchange rate variability among these currencies or relative to the U.S. dollar. While we take steps tomanage currency exchange rate exposure, including entering into hedging transactions, we cannot eliminate all exposure to futureexchange rate variability. These exchange risks could 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 materialsare derived from petrochemical-based and vegetable-based feedstocks which can be subject to periods of rapid and significant costinstability. These fluctuations in cost can be caused by political instability in oil producing nations and 14Table of Contentselsewhere, or other factors influencing global supply and demand of these materials, over which we have little or no control. We uselong-term contracts (generally with fixed or formula-based costs) and advance bulk purchases to help ensure availability andcontinuity of supply, and to manage the risk of cost increases. From time to time, we have entered into hedging arrangements forcertain utilities and raw materials, but do not typically enter into hedging arrangements for all raw materials, chemicals or energycosts. If the costs of raw materials, chemicals or energy increase, and we are not able to pass on these cost increases to ourcustomers, then profit margins and cash flows from operating activities would be adversely impacted. If raw material costs increasesignificantly, then our need for working capital could increase. Any of these risks 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 ofoperations. Although we try to anticipate problems with supplies of raw materials or transportation services by building certain inventories ofstrategic importance, transport operations are exposed to various risks such as extreme weather conditions, natural disasters,technological problems, work stoppages 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 andtimely means to obtain raw materials or ship finished products, which could adversely impact our results of operations, financialposition and cash flows. A high concentration of significant stockholders may have a material adverse impact on our stock price. Approximately 38% of our common stock is held by four stockholders. A decision by any of these stockholders to sell all or asignificant part of its holding, or a sudden or unexpected disposition of our stock, could result in a significant decline in our stockprice which could in turn adversely impact our ability to access equity markets which in turn could adversely impact our results ofoperations, financial position and cash flows. 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 othercompanies for infringing on their intellectual property rights. Measures taken by us to protect our intellectual property may bechallenged, invalidated, circumvented or rendered unenforceable. We may also face patent infringement claims from our competitorswhich may result in substantial litigation costs, claims for damages or a tarnishing of our reputation even if we are successful indefending against these claims, which may cause our customers to switch to our competitors. Any of these events could adverselyimpact our results of operations, financial position and cash flows. 15Table of ContentsOur 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 approvalof our products, manufacturing processes and facilities before we may sell certain products. Many products are required to beregistered with the U.S. Environmental Protection Agency (EPA), with the European Chemicals Agency (ECHA) and withcomparable government agencies elsewhere. We are also subject to ongoing reviews of our products, manufacturing processes andfacilities 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 isappropriate and effective for its intended uses, and that we are capable of manufacturing the product in accordance with applicableregulations. This approval process can be costly, time consuming, and subject to unanticipated and significant delays. We cannot besure that necessary approvals will be granted on a timely basis or at all. Any delay in obtaining, or any failure to obtain or maintain,these approvals would adversely affect our ability to introduce new products and to generate income from those products. New orstricter laws and regulations may be introduced that could result in additional compliance costs and prevent or inhibit thedevelopment, manufacture, distribution and sale of our products. Such outcomes could adversely impact our results of operations,financial position and cash flows. 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, includingemployee and product liability claims. Although we maintain insurance to protect us against a variety of claims, if our insurancecoverage is not adequate to cover such claims, then we may be required to pay directly for such liabilities. Such outcomes couldadversely 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 andsafety laws and regulations, including 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 environmentalpermits and licenses, many of which require periodic notification and renewal, which is not automatic. New or stricter laws andregulations could increase our compliance burden or costs and adversely affect our ability to develop, manufacture, blend, marketand supply products. Our operations, and the operations of prior owners of our sites, pose the risk of environmental contamination which may result infines or criminal sanctions being imposed or require significant amounts in remediation payments. 16Table of ContentsWe anticipate that certain manufacturing sites may cease production over time and on closure, will require safely decommissioningand some environmental remediation. The extent of our obligations will depend on the future use of the sites that are affected and theenvironmental laws in effect at the time. We currently have made a decommissioning and remediation provision in our consolidatedfinancial statements based on current known obligations, anticipated plans for sites and existing environmental laws. If there were tobe unexpected or unknown contamination at these sites, or future plans for the sites or environmental laws change, then currentprovisions may prove inadequate, 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 ofoperations. We sell products to oil companies, oil and gas exploration and production companies and chemical companies throughout the world.Credit limits, ongoing credit evaluation and account monitoring procedures are used to minimize bad debt risk. Collateral is notgenerally required. We have in place a credit facility with a syndicate of banks. From time to time, we use derivatives, includinginterest rate swaps, commodity swaps and foreign currency forward exchange contracts, in the normal course of business to managemarket risks. We enter into derivative instruments with a diversified group of major financial institutions in order to manage theexposure 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 thepotential non-performance of counterparties to deliver contracted commodities or services at the contracted price. The inability ofcounterparties to meet their contractual obligations could have an adverse impact on our results of operations, financial position andcash flows. The provisions of our term loan and revolving credit facility may restrict our ability to incur additional indebtedness or tootherwise expand our business. Our term loan and revolving credit facility contains restrictive clauses which may limit our activities, and operational and financialflexibility. We may not be able to borrow under the credit facility if an event of default under the terms of the facility occurs. Anevent of default under the term loan and credit facility includes a material adverse change to our assets, operations or financialcondition, and certain other events. The term loan and revolving credit facility also contains a number of restrictions that limit ourability, 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 changeour line of business. In addition, the term loan and revolving credit facility requires us to meet certain financial ratios, including ratios based on net debtto EBITDA and net interest expense to EBITDA. Net debt, net interest expense and EBITDA are non-GAAP measures of liquiditydefined in the credit facility. Our ability to meet these financial covenants depends upon the future 17Table of Contentssuccessful operating performance of the business. If we fail to comply with financial covenants, we would be in default under theterm loan and revolving credit facility and the maturity of our outstanding debt could be accelerated unless we were able to obtainwaivers from our lenders. If we were found to be in default under the term loan and revolving credit facility, it could adverselyimpact 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 ofoperations. We are subject to hazards which are common to chemical manufacturing, blending, storage, handling and transportation. Thesehazards include fires, explosions, remediation, chemical spills and the release or discharge of toxic or hazardous substances togetherwith the more generic risks of labor strikes or slowdowns, mechanical failure in scheduled downtime, extreme weather ortransportation interruptions. These hazards could result in loss of life, severe injury, property damage, environmental contaminationand temporary or permanent manufacturing cessation. Any of these factors could adversely impact our results of operations, financialposition and cash flows. Domestic or international natural disasters or terrorist attacks may disrupt our operations, decrease the demand for our productsor 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 targetsin the U.S., the United Kingdom and throughout the world. Extraordinary events such as natural disasters may negatively affect localeconomies, including those of our customers or suppliers. The occurrence and consequences of such events cannot be predicted, butthey can adversely impact economic conditions in general and in our specific markets. The resulting damage from such events couldinclude loss of life, severe injury and property damage or site closure. Any of these matters could adversely impact our results ofoperations, financial position and cash flows. While Innospec maintains business continuity plans that are intended to allow it to continue operations or mitigate the effects ofevents that could disrupt its business, Innospec cannot provide assurances that its plans would fully protect it from all such events. Inaddition, insurance maintained by Innospec to protect against property damage, loss of business and other related consequencesresulting from catastrophic events is subject to coverage limitations, depending on the nature of the risk insured. This insurance maynot be sufficient to cover all of Innospec’s damages or damages to others in the event of a catastrophe. In addition, insurance relatedto these types of risks may not be available now or, if available, may not be available in the future at commercially reasonable rates. 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 oradditional requirements, additional charges to fund energy efficiency activities, fees or restrictions on certain activities. Compliancewith these 18Table of Contentsinitiatives 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 adopted future climate change regulationscould also negatively impact our ability to compete with companies situated in areas not subject to such limitations. Even withoutsuch regulation, increased public awareness and adverse publicity about potential impacts on climate change emanating from us orour 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 changeand related regulation on our customers are highly uncertain and may adversely affect us.

EXECUTIVE OVERVIEW In 2017, our sales grew in line with our expectations, as we delivered on our strategy to grow all of our strategic business units. Salesin Fuel Specialties and Performance Chemicals reflected the strength of our product portfolio and research and development pipelinein these markets. Our Oilfield Services segment experienced strong growth, reflecting the increase in customer activity, as the marketrecovered. Our Octane Additives segment performance was in line with the final stages of transition to unleaded gasoline in the automotivemarket. Our Avtel product line, producing TEL for Avgas 100LL for piston engine aircraft, is included in our Fuel Specialtiessegment. We anticipate that this product line will decline when an alternative to Avgas 100LL is proven, and a deliverable transitionplan is developed. During the year, we completed the integration of the business acquired from Huntsman at the end of 2016. From the first quarter of2018, Performance Chemicals will be reported as a single business in our commentary, and we will no longer report the detailed splitbetween the acquired and heritage businesses. CRITICAL ACCOUNTING ESTIMATES Note 2 of the Notes to the Consolidated Financial Statements includes a summary of the significant accounting policies and methodsused in the preparation of the consolidated financial statements. Business combinations The acquisition method of accounting requires that we recognize the assets acquired and liabilities assumed at their acquisition datefair values. Goodwill is measured as the excess of consideration transferred over the acquisition date net fair values of the assetsacquired and the liabilities assumed. The measurement of the fair values of assets acquired and liabilities assumed requires considerable judgment. Although independentappraisals may be used to assist in the determination of the fair values of certain assets and liabilities, those determinations areusually based on significant estimates provided by management, such as forecast revenue or profit. In determining the fair value ofintangible assets, an income approach is generally used and may incorporate the use of a discounted cash flow method. In applyingthe discounted cash flow method, the estimated future cash flows and residual values for each intangible asset are discounted to apresent value using a discount rate appropriate to the business being 26Table of Contentsacquired. These cash flow projections are based on management’s estimates of economic and market conditions including revenuegrowth rates, operating margins, capital expenditures and working capital requirements. While we use our best estimates and assumptions as part of the process to value assets acquired and liabilities assumed at theacquisition date and contingent consideration at each balance sheet reporting date, our estimates are inherently uncertain and subjectto refinement. During the measurement period, which occurs before finalization of the purchase price allocation, changes inassumptions and estimates based on new information that was not previously available, that result in adjustments to the fair values ofassets acquired and liabilities assumed will have a corresponding offset to goodwill. Subsequent adjustments will impact ourconsolidated statements of income. Environmental Liabilities We are subject to environmental laws in the countries in which we conduct business. Our principal site giving rise to environmentalremediation liabilities is the Octane Additives manufacturing site at Ellesmere Port in the United Kingdom. There are alsoenvironmental remediation liabilities on a much smaller scale in respect of our other manufacturing sites in the U.S. and Europe. AtEllesmere Port there is a continuing asset retirement program related to certain manufacturing units that have been closed. Remediation provisions at December 31, 2017 amounted to $46.1 million and relate principally to our Ellesmere Port site in theUnited Kingdom. We recognize environmental liabilities when they are probable and costs can be reasonably estimated, and assetretirement obligations when there is a legal obligation and costs can be reasonably estimated. The Company has to anticipate theprogram of work required and the associated future expected costs, and comply with environmental legislation in the countries inwhich it operates or has operated in. The Company views the costs of vacating our Ellesmere Port site as contingent upon if andwhen it vacates the site because there is no present intention to do so. Pensions The Company maintains a defined benefit pension plan covering a number of its current and former employees in the UnitedKingdom. The Company also has other much smaller pension arrangements in the U.S. and overseas, but the obligations under thoseplans are not material. The United Kingdom plan is closed to future service accrual, but has a large number of deferred and currentpensioners. Movements in the underlying plan asset value and Projected Benefit Obligation (“PBO”) are dependent on actual return oninvestments as well as our assumptions in respect of the discount rate, annual member mortality rates, future return on assets andfuture inflation. A change in any one of these assumptions could impact the plan asset value, PBO and pension charge recognized inthe income statement. Such changes could adversely impact our results of operations and financial position. For example, a 0.25%change in the discount rate 27Table of Contentsassumption would change the PBO by approximately $25 million while the net pension credit for 2018 would change byapproximately $0.1 million. A 0.25% change in the level of price inflation assumption would change the PBO by approximately$18 million and the net pension credit for 2018 would change by approximately $1.5 million. Further information is provided in Note 9 of the Notes to the Consolidated Financial Statements. Income Taxes We are subject to income and other taxes in the U.S. and other jurisdictions. Tax laws are dynamic and subject to change as new lawsare 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 taxregulations. 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 liabilityand 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 technicalmerits, 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 our liabilities, our effective tax rate in a given period may be materially affected. Anunfavorable tax settlement may require cash payments and result in an increase in our effective tax rate in the year of resolution. Afavorable tax settlement may be recognized as a reduction in our effective tax rate in the year of resolution. We report interest andpenalties related to uncertain income tax positions as income taxes. For additional information regarding uncertain income taxpositions, see Note 10 of the Notes to the Consolidated Financial Statements. On December 22, 2017, the U.S. Tax Cuts and Jobs Act (the “Tax Reform Act”) was enacted and significantly revises the U.S.corporate income tax regime. The new legislation contains several key tax provisions that affect us, including a one-time mandatorytransition tax on accumulated foreign earnings and a reduction in the U.S. corporate income tax rate from 35% to 21% effectiveJanuary 1, 2018, amongst others. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance onaccounting for the tax effects of the Tax Reform Act. SAB 118 provides a measurement period that should not extend beyond oneyear from the Tax Reform Act enactment date for companies to complete their accounting under ASC 740, Income Taxes . Untilaccounting is complete, companies may record provisional estimates. As a result of the Tax Reform Act, we have recordedprovisional amounts in relation to the accounting of the transition tax in 2017. We consider the accounting of the transition tax andother items as 28Table of Contentsfurther disclosed in Note 10 to be incomplete due to the forthcoming guidance and our ongoing analysis of final data and taxpositions which may impact these calculations. We expect to complete our analysis within the measurement period in accordance with SAB 118. Goodwill The Company’s reporting units, the level at which goodwill is assessed for potential impairment, are consistent with the reportablesegments. The components in each segment (including products, markets and competitors) have similar economic characteristics andthe segments, therefore, reflect the lowest level at which operations and cash flows can be sufficiently distinguished, operationallyand for financial reporting purposes, from the rest of the Company. Initially the Company performs a qualitative assessment to determine whether it is more likely than not that the fair value of asegment is less than the carrying amount prior to performing the two-step goodwill impairment test. If a two-step test is required weassess the fair value based on projected post-tax cash flows discounted at the Company’s weighted average cost of capital. At December 31, 2017 we had $361.8 million of goodwill relating to our Fuel Specialties, Performance Chemicals and OilfieldServices segments. Our impairment assessment concluded that there had been no impairment of goodwill in respect of thosereporting segments. While we believe our assumptions for impairment assessments are reasonable, they are subjective judgments, and it is possible thatvariations in any of the assumptions may result in materially different calculations of any potential impairment charges. Property, Plant and Equipment and Other Intangible Assets (Net of Depreciation and Amortization, respectively) As at December 31, 2017 we had $196.0 million of property, plant and equipment and $163.3 million of other intangible assets (netof depreciation and amortization, respectively), that are discussed in Notes 6 and 8 of the Notes to the Consolidated FinancialStatements, respectively. These long-lived assets relate to all of our reporting segments and are being amortized or depreciatedstraight-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, plantand equipment. We continually assess the markets and products related to these long-lived assets, as well as their specific carrying values, and haveconcluded that these carrying values, and amortization and depreciation periods, remain appropriate. 29Table of ContentsWe also test these long-lived assets for any potential impairment when events occur or circumstances change which suggests thatimpairment may have occurred. These types of events or changes in circumstances could include, but are not limited to: • introduction of new products with enhanced features by our competitors; • loss of, material reduction in purchases by, or non-renewal of a contract by a significant customer; • prolonged decline in business or consumer spending; • sharp and unexpected rise in raw material, chemical or energy costs; and • new laws or regulations inhibiting the development, manufacture, distribution or sale of our products. In order to facilitate this testing the Company groups together assets at the lowest possible level for which cash flow information isavailable. Undiscounted future cash flows expected to result from the asset groups are compared with the carrying value of the assetsand, if such cash flows are lower, an impairment loss may be recognized. The amount of the impairment loss is the differencebetween the fair value and the carrying value of the assets. Fair values are determined using post-tax cash flows discounted at theCompany’s weighted average cost of capital. If events occur or circumstances change it may cause a reduction in periods over whichthese long-lived assets are amortized or depreciated, or result in a non-cash impairment of a portion of their carrying value. Areduction in amortization or depreciation periods would have no effect on cash flows. 30Table of ContentsRESULTS OF OPERATIONS The following table provides operating income by reporting segment: (in millions) 2017 2016 2015 Net sales: Fuel Specialties $523.8 $509.6 $532.8 Performance Chemicals 419.5 138.7 155.0 Oilfield Services 304.4 191.7 265.0 Octane Additives 59.1 43.4 59.5 $1,306.8 $883.4 $1,012.3 Gross profit: Fuel Specialties $188.2 $186.4 $176.0 Performance Chemicals 75.8 43.4 42.4 Oilfield Services 109.3 76.4 99.1 Octane Additives 30.0 26.1 28.5 $403.3 $332.3 $346.0 Operating income: Fuel Specialties $107.1 $110.6 $102.1 Performance Chemicals 32.6 16.0 16.3 Oilfield Services 9.5 (4.7) 9.0 Octane Additives 26.7 22.7 24.7 Pension credit 4.4 6.7 0.2 Corporate costs (47.9) (53.9) (38.3) Adjustment to fair value of contingent consideration 0.0 9.4 40.7 (Loss)/profit on disposal of subsidiary (0.9) (1.4) 1.6 Foreign exchange loss on liquidation of subsidiary (1.8) 0.0 0.0 Total operating income $129.7 $105.4 $156.3 Included in net income: Other income/(expense), net $6.6 $0.9 $0.0 Interest expense, net (8.2) (3.2) (4.0) Income before income taxes 128.1 103.1 152.3 Income taxes (66.3) (21.8) (32.8) Net income $61.8 $81.3 $119.5 31Table of ContentsResults of Operations – Fiscal 2017 compared to Fiscal 2016: (in millions, except ratios) 2017 2016 Change Net sales: Fuel Specialties $523.8 $509.6 $14.2 +3% Performance Chemicals 419.5 138.7 280.8 n/a Oilfield Services 304.4 191.7 112.7 +59% Octane Additives 59.1 43.4 15.7 +36% $1,306.8 $883.4 $423.4 +48% Gross profit: Fuel Specialties $188.2 $186.4 $1.8 +1% Performance Chemicals 75.8 43.4 32.4 +75% Oilfield Services 109.3 76.4 32.9 +43% Octane Additives 30.0 26.1 3.9 +15% $403.3 $332.3 $71.0 +21% Gross margin (%): Fuel Specialties 35.9 36.6 -0.7 Performance Chemicals 18.1 31.3 -13.2 Oilfield Services 35.9 39.9 -4.0 Octane Additives 50.8 60.1 -9.3 Aggregate 30.9 37.6 -6.7 Operating expenses: Fuel Specialties $(81.1) $(75.8) $(5.3) +7% Performance Chemicals (43.2) (27.4) (15.8) +58% Oilfield Services (99.8) (81.1) (18.7) +23% Octane Additives (3.3) (3.4) 0.1 -3% Pension credit 4.4 6.7 (2.3) -34% Corporate costs (47.9) (53.9) 6.0 -11% Adjustment to fair value of contingent consideration 0.0 9.4 (9.4) n/a Loss on disposal of subsidiary (0.9) (1.4) 0.5 -36% Foreign exchange loss on liquidation of subsidiary (1.8) 0.0 (1.8) n/a $(273.6) $(226.9) $(46.7) +21% Fuel Specialties Net sales: the table below details the components which comprise the year on year change in net sales spread across the markets inwhich we operate: Change (%) Americas EMEA ASPAC AvTel Total Volume +11 -10 -1 -16 -3 Price and product mix -6 +11 +6 +7 +5 Exchange rates 0 +2 0 0 +1 +5 +3 +5 -9 +3 32Table of ContentsVolumes in the Americas were higher as a result of increased demand following a slower than normal end to 2016. Price and productmix in the Americas was adversely impacted by increased sales of lower margin products. Volumes in EMEA and ASPAC decreaseddue to customer reformulation to our new technologies. Price and product mix in EMEA and ASPAC benefited from increased salesof higher margin products. AvTel volumes were lower than the prior year due to variations in the timing and level of demand fromcustomers, together with a favorable price mix. EMEA benefited from favorable exchange rate movements year over year, driven bya strengthening of the European Union euro against the U.S. dollar. Gross margin: the year on year decrease of 0.7 percentage points was adversely impacted by lower sales of higher margin productscompared to a strong prior year, partly offset by the benefit of a stronger European Union euro versus the U.S. dollar towards the endof the year. Operating expenses: the year on year increase of $5.3 million was driven by $3.4 million higher selling and administrative expensesand $1.9 million higher research and development expenses. Higher performance based personnel-related compensation hasincreased expenses year on year. Performance Chemicals Net sales: the table below details the components which comprise the year on year change in net sales spread across the markets inwhich we operate: Change (%) Americas EMEA ASPAC Acquisition Total Volume +16 +5 +11 0 +13 Acquisition 0 0 0 +195 +195 Price and product mix -8 +4 -7 0 -6 Exchange rates 0 0 -1 0 0 +8 +9 +3 +195 +202 Excluding the Huntsman acquisition, increased Personal Care demand led to higher volumes in all our markets. Price and productmix in the Americas and ASPAC was adversely affected by pricing pressures in Personal Care, while EMEA benefited fromfavorable price and product mix in Personal Care. ASPAC was adversely impacted by exchange rate movements’ year over year,driven by a weakening of the British pound sterling against the U.S. dollar. Sales growth from the acquisition of our Huntsmanbusiness at the end of 2016 has been excluded from the market analysis above and included as one variance for the segment total. Gross margin: the year on year decrease of 13.2 percentage points was driven by the dilutive effect of the lower margins for ouracquired Huntsman business together with some one-off events for an unplanned plant outage and raw materials purchasing andpricing issues in the second quarter for the acquired business. Operating expenses: the year on year increase of $15.8 million is due to $17.6 million additional expenses within our acquiredHuntsman business, partly offset by a reduction in performance based personnel-related compensation and the favorable impact of a$1.0 million one-off commercial legal settlement in the prior year. 33Table of ContentsOilfield Services Net sales: the year on year increase of $112.7 million was due to an improvement in customer demand for all our product linesfollowing the rising customer activity as oil prices have recovered. Overall volumes increased by 60 percent year on year, partlyoffset by an adverse price and product mix of 1 percent. Gross margin: the year on year decrease of 4.0 percentage points, compared with a strong prior year, is driven by the mix ofcustomer activity and the adverse effect of Hurricane Harvey on raw material prices and availability. Operating expenses: the year on year increase of $18.7 million was primarily driven by $15.3 million higher selling and technicalsupport expenses required to service the increase in customer demand, together with $1.2 million additional research anddevelopment expenses and $2.2 million higher administration costs to support the business growth. Octane Additives Net sales: have increased by $15.7 million compared to the prior year, due to the phasing of orders from our one remaining refinerycustomer. Gross margin: the year on year decrease of 9.3 percentage points was due to lower volumes of production in the current year leadingto higher manufacturing costs per tonne. Operating expenses: the year on year decrease of $0.1 million was primarily due to a reduction in the provisions for doubtful debts. Other Income Statement Captions Pension credit: is non-cash, and was a $4.4 million net credit in 2017 compared to a $6.7 million net credit in 2016 primarily drivenby higher amortization of actuarial losses. Corporate costs: the year on year decrease of $6.0 million related to $4.4 million non-recurring acquisition-related costs in the prioryear for our Huntsman business, partly offset by $1.9 million of integration related costs in the current year; together with lowerperformance based personnel-related compensation and the benefit of the weaker British pound sterling against the U.S. dollar forour Ellesmere Port cost base over the year. Adjustment to fair value of contingent consideration: in the prior year there was a contingent consideration credit of $9.4 millionrelated to an acquisition in 2014. Loss on disposal of subsidiary: the loss of $0.9 million relates to an indemnity claim in relation to residual testing in the AromaChemicals business which was sold in 2015. Foreign exchange loss on liquidation of subsidiary: the $1.8 million loss relates to the reclassification of historic foreign exchangetranslations of net assets from accumulated other comprehensive losses, for our captive insurance company which was liquidated inthe first quarter of 2017. 34Table of ContentsOther net income/(expense): other net income of $6.6 million related to $7.5 million of gains on translation of net balancesdenominated in non-functional currencies mainly in our European businesses, partly offset by losses of $0.9 million on foreigncurrency forward exchange contracts. In the prior year, other net income of $0.9 million primarily related to $4.4 million net gains onforeign currency forward contracts, partly offset by losses of $3.5 million on translation of net assets denominated in non-functionalcurrencies in our European businesses. Interest expense, net: was $8.2 million in 2017 compared to $3.2 million in 2016, driven by the additional term loan related to theHuntsman acquisition, increased working capital requirements funded by our credit facility and the recent rise in LIBOR impactingour revolving credit facility borrowing. Income taxes: The effective tax rate was 51.8% and 21.1% in 2017 and 2016, respectively. The adjusted effective tax rate, onceadjusted for the items set out in the following table, was 20.2% in 2017 compared with 22.4% in 2016. The Company believes thatthis adjusted effective tax rate, a non-GAAP financial measure, provides useful information to investors and may assist them inevaluating the Company’s underlying performance and identifying operating trends. In addition, management uses this non-GAAPfinancial measure internally to evaluate the performance of the Company’s operations and for planning and forecasting in subsequentperiods.

As a result of the Act,we accrued a provisional estimate of the mandatory 35Table of Contentstransition tax on our accumulated earnings as of December 31, 2017, resulting in an increase to income tax expense of $47.7 million.In addition, our U.S. deferred tax assets and liabilities were re-measured from 35% to 21% at the same date, which resulted in$7.1 million of deferred income tax benefit. In addition to those mentioned above, the mix of taxable profits in the different geographical jurisdictions in which the Groupoperates continues to have a significant positive impact on the effective tax rate. The foreign tax rate differential arising from profits being earned in foreign jurisdictions with lower tax rates in 2017 was$17.5 million (2016 – $17.1 million). In 2017, the Company’s income tax expense benefited to a greater degree from a proportion ofits overall profits arising in Switzerland than in 2016. This resulted in an $8.2 million benefit in Switzerland (2016 – $7.8 million). Inaddition, there was an $8.3 million benefit in relation to the United Kingdom (2016 – $8.4 million), a $0.7 million benefit in relationto Germany (2016 – $0.5 million), and a $0.3 million benefit in other jurisdictions (2016 – $0.3 million benefit). Foreign income inclusions arise each year from certain types of income earned overseas being taxable under U.S. tax regulations.The Tax Reform Act will substantially change the U.S. taxation of income earned overseas in 2018 and future years. In 2017, incomeearned overseas and taxable under U.S. regulations includes Subpart F income, principally from foreign based company sales in theUnited Kingdom, and the associated Section 78 tax gross up, and also from the income earned by certain overseas subsidiariestaxable under the U.S. tax regime. In 2017, Subpart F income and the associated Section 78 gross up resulted in U.S. taxation of$7.1 million (2016 – $5.7 million). Certain overseas subsidiaries taxable under the U.S. tax regime generated taxable income of$2.4 million (2016 – $0.2 million loss). Foreign tax credits can fully or partially offset these incremental U.S. taxes from foreign income inclusions. The utilization offoreign tax credits varies year on year as this is dependent on a number of variable factors which are difficult to predict and may incertain years prevent any offset of foreign tax credits. In total, $5.6 million of foreign tax credits were utilized during 2017 to offsetthe incremental U.S. taxes arising from foreign income inclusions in the year, excluding those associated with the one-timemandatory transition tax inclusion (2016 – $6.1 million), all generated during 2017. Further details are given in Note 10 of the Notes to the Consolidated Financial Statements. 36Table of ContentsResults of Operations – Fiscal 2016 compared to Fiscal 2015: (in millions, except ratios) 2016 2015 Change Net sales: Fuel Specialties $509.6 $532.8 $(23.2) -4% Performance Chemicals 138.7 155.0 (16.3) -11% Oilfield Services 191.7 265.0 (73.3) -28% Octane Additives 43.4 59.5 (16.1) -27% $883.4 $1,012.3 $(128.9) -13% Gross profit: Fuel Specialties $186.4 $176.0 $10.4 +6% Performance Chemicals 43.4 42.4 1.0 +2% Oilfield Services 76.4 99.1 (22.7) -23% Octane Additives 26.1 28.5 (2.4) -8% $332.3 $346.0 $(13.7) -4% Gross margin (%): Fuel Specialties 36.6 33.0 +3.6 Performance Chemicals 31.3 27.4 +3.9 Oilfield Services 39.9 37.4 +2.5 Octane Additives 60.1 47.9 +12.2 Aggregate 37.6 34.2 +3.4 Operating expenses: Fuel Specialties $(75.8) $(73.9) $(1.9) +3% Performance Chemicals (27.4) (26.1) (1.3) +5% Oilfield Services (81.1) (90.1) 9.0 -10% Octane Additives (3.4) (3.8) 0.4 -11% Pension credit 6.7 0.2 6.5 n/a Corporate costs (53.9) (38.3) (15.6) +41% Adjustment to fair value of contingent consideration 9.4 40.7 (31.3) +77% (Loss)/profit on disposal of subsidiary (1.4) 1.6 (3.0) n/a $(226.9) $(189.7) $(37.2) +20% Fuel Specialties Net sales: the table below details the components which comprise the year on year change in net sales spread across the markets inwhich we operate: Change (%) Americas EMEA ASPAC AvTel Total Volume -14 +11 +3 +4 0 Price and product mix -2 -9 -1 +4 -3 Exchange rates 0 -1 0 0 -1 -16 +1 +2 +8 -4 37Table of ContentsVolumes in the Americas were lower than the prior year due to softer fuel demand, a warmer winter and a change in the refinerycrude slates. EMEA and ASPAC volumes increased from the prior year driven by increased demand for high volume low marginproducts. Price and product mix in EMEA and ASPAC was adversely impacted by the increased sales of lower margin productstogether with some pricing pressures. AvTel volumes were higher than the prior year due to new customer orders combined with afavorable price and product mix from a richer customer mix. EMEA was adversely impacted by exchange rate movements year overyear, driven by a weakening of the European Union euro and the British pound sterling against the U.S. dollar. Gross margin: the year on year increase of 3.6 percentage points was primarily achieved from reduced sales of lower marginproducts in the Americas, together with the positive effect of weaker exchange rates versus the U.S. dollar on our cost base in EMEAand ASPAC and the higher margin contribution from additional AvTel volumes. Operating expenses: the year on year increase of $1.9 million, was primarily driven by increased share-based compensation accrualsdue to the rise in the Innospec share price in the year together with increased provisions against doubtful debts.

Americas and EMEA experienced pricingpressures in Personal Care which adversely affected the price and product mix. ASPAC benefited from favorable pricing in PersonalCare. A weakening of the European Union euro and British pound sterling against the U.S. dollar resulted in an adverse exchangerate variance for EMEA and ASPAC. The disposal of our Aroma Chemicals business in 2015 has been excluded from the marketanalysis above and included as one variance for the segment total. Gross margin: the year on year increase of 3.9 percentage points was primarily driven by a greater proportion of sales from ourhigher margin Personal Care business following the disposal of our lower margin Aroma Chemicals business in the prior year,together with the positive effect of weaker exchange rates versus the U.S. dollar on our cost base in EMEA and ASPAC. 38Table of ContentsOperating expenses: the year on year increase of $1.3 million is primarily due to a $1.0 million commercial legal settlement with adistributor; together with higher share-based compensation accruals driven by the rise in the Innospec share price in the year andhigher performance related compensation; partly offset by a $0.6 million reduction due to the disposal of our Aroma Chemicalsbusiness in the prior year. Oilfield Services Net sales: the year on year decrease of $73.3 million was primarily due to a reduction in customer activity especially in wellcompletion, following the decline in oil prices in prior years. Customer activity and confidence has improved in 2016 leading to a22% growth in sales for the fourth quarter compared to the fourth quarter of 2015. Overall volumes declined by 13 percent year onyear, together with an adverse price and product mix of 15 percent. Gross margin: the year on year increase of 2.5 percentage points was primarily due to a favorable sales mix driven by a higherproportion of sales from our higher margin production business. Operating expenses: the year on year decrease of $9.0 million was driven by our cost reduction programs and lower selling andtechnical support expenses to align with the decline in customer demand. Octane Additives Net sales: have decreased by $16.1 million compared to the prior year due to the phasing of orders from our one remaining refinerycustomer. Gross margin: the year on year increase of 12.2 percentage points was primarily due to higher volumes of production in 2016generating favorable manufacturing variances together with the benefit of a weaker British pound sterling against the U.S. dollar forour Ellesmere Port cost base. Operating expenses: the year on year decrease of $0.4 million was due to the continuing efficient management of the cost base andthe benefit of a weaker British pound sterling against the U.S. dollar for our Ellesmere Port cost base. Other Income Statement Captions Pension credit: is non-cash, and was a $6.7 million net credit in 2016 compared to a $0.2 million net credit in 2015 primarily drivenby lower interest cost on the projected benefit obligation. Corporate costs: the year on year increase of $15.6 million, related to $4.6 million higher amortization and other costs related to theEMEA and ASPAC deployment of our group wide ERP system; $4.4 million acquisition-related professional fees; $3.2 millionhigher legal, professional and other expenses primarily due to the recovery of legal fees in the prior year 39Table of Contentsand a $3.4 million increase related to higher personnel-related compensation, including higher accruals for share-based compensationdriven by the rise in the Innospec share price in the year. Adjustment to fair value of contingent consideration: the credit of $9.4 million relates to an adjustment to the carrying value of ourliability for contingent consideration of $10.3 million, partly offset by the accretion charge of $0.9 million, both in relation to ouracquisition of Independence Oilfield Chemicals LLC (“Independence”). The contingent consideration payable at December 31, 2016has been calculated based on the actual trading results through the period to October 31, 2016, although the amount to be paid issubject to final agreement with the previous owners. (Loss)/profit on disposal of subsidiary: the disposal of our Aroma Chemicals business generated a $1.4 million loss on disposal in2016 compared to a profit on disposal of $1.6 million in the prior year. The loss on disposal in 2016 related to the finalization of theassets and liabilities disposed. Other net income/(expense): other net income of $0.9 million primarily related to $4.4 million net gains on foreign currency forwardcontracts, partly offset by losses of $3.5 million on translation of net assets denominated in non-functional currencies in ourEuropean businesses. In 2015, other net expense of $0.0 million primarily related to gains of $1.4 million on foreign currencyforward exchange contracts, offset by $1.4 million of losses on translation of net assets denominated in non-functional currencies inour European businesses. Interest expense, net: was $3.2 million in 2016 compared to $4.0 million in 2015, with the reduction being due to the higheramortization of deferred finance costs in the prior year, lower average net debt in 2016 and lower borrowing costs within our revisedcredit facility, partly offset by the rise in LIBOR during 2016. Income taxes: the effective tax rate was 21.1% and 21.5% in 2016 and 2015, respectively. The effective tax rate, as adjusted forchanges to the fair value of contingent consideration, adjustments to income tax positions and the tax impact of other discrete items,was 22.4% in 2016 compared with 20.1% in 2015. The Company believes that this adjusted effective tax rate, a non-GAAP financialmeasure, provides useful information to investors and may assist them in evaluating the Company’s underlying performance andidentifying operating trends. In addition, management uses this non-GAAP financial measure internally to evaluate the performanceof the Company’s operations and for planning and forecasting in subsequent periods. 40Table of Contents(in millions, except ratios) 2016 2015 Income before income taxes $103.1 $152.3 Adjustment to fair value of contingent consideration (9.4) (40.7) Adjustment to acquisition accounting for inventory fair valuation 0.0 3.7 Loss/(profit) on disposal of subsidiary 1.4 (1.6) $95.1 $113.7 Income taxes $21.8 $32.8 Add back adjustment of income tax provisions 1.6 2.3 Add back tax on adjustments to fair value of contingent consideration (3.6) (15.5) Add back other discrete items 1.5 3.2 $21.3 $22.8 GAAP effective tax rate 21.1% 21.5% Adjusted effective tax rate 22.4% 20.1% In addition to those mentioned above, the following factors had a significant impact on the Company’s effective tax rate as comparedto the U.S. federal income tax rate of 35%: (in millions) 2016 2015 Foreign tax rate differential $(17.1) $(14.5) Foreign income inclusions 0.5 2.7 Deferred tax credit from United Kingdom income tax rate reduction on pensions (0.6) (1.1) The impact on the effective tax rate from profits earned in foreign jurisdictions with lower tax rates varies as the geographical mix ofthe Company’s profits changes year on year. In 2016, the Company’s income tax expense benefited to a greater degree from aproportion of its overall profits arising in Switzerland than in 2015. This resulted in a $7.8 million benefit in Switzerland (2015 –$7.5 million). In addition, there was an $8.4 million benefit in relation to the United Kingdom (2015 – $6.8 million) and a$0.5 million benefit in relation to Germany (2015 – $0.3 million), and a $0.3 million benefit in other jurisdictions (2015 –$0.1 million reduction). Foreign income inclusions arise each year from certain types of income earned overseas being taxable under U.S. tax regulations.These types of income include Subpart F income, principally from foreign based company sales in the United Kingdom, includingthe associated Section 78 tax gross up, and also from the income earned by certain overseas subsidiaries taxable under the U.S. taxregime. In 2016, Subpart F income and the associated Section 78 gross up resulted in U.S. taxation of $5.7 million (2015 – $4.7million). Certain overseas subsidiaries taxable under the U.S. tax regime incurred losses of $0.2 million (2015 – $0.2 million losses). Foreign tax credits can fully or partially offset these incremental U.S. taxes from foreign income inclusions. The utilization offoreign tax credits varies year on year as this is 41Table of Contentsdependent on a number of variable factors which are difficult to predict and may in certain years prevent any offset of foreign taxcredits. In total, $6.1 million of foreign tax credits were utilized during 2016 to offset the incremental U.S. taxes arising from foreignincome inclusions in the year (2015 – $4.7 million). Of this balance, $0.5 million of foreign tax credit carry forwards from earlieryears was utilized (2015 – $2.4 million). As at December 31, 2016, the Company has utilized all foreign tax credit carry forwardsfrom earlier years. The United Kingdom’s 1% reduction in the corporation tax rate effective from April 2020 from 18% to 17%, enacted in September2016, resulted in a deferred tax credit of $0.6 million in the fourth quarter of 2016 primarily in relation to the deferred tax position ofthe United Kingdom defined benefit pension plan. Further details are given in Note 10 of the Notes to the Consolidated Financial Statements. LIQUIDITY AND FINANCIAL CONDITION Working Capital The Company believes that adjusted working capital, a non-GAAP financial measure, provides useful information to investors inevaluating the Company’s underlying performance and identifying operating trends. Management uses this non-GAAP financialmeasure internally to allocate resources and evaluate the performance of the Company’s operations. Items excluded from theadjusted working capital calculation are listed in the table below and represent factors which do not fluctuate in line with the day today working capital needs of the business. (in millions) 2017 2016 Total current assets $561.5 $441.1 Total current liabilities (261.6) (183.1) Working capital 299.9 258.0 Less cash and cash equivalents (90.2) (101.9) Less prepaid income taxes (2.8) (4.8) Less other current assets (1.1) 0.0 Add back current portion of accrued income taxes 15.8 9.4 Add back current portion of long-term debt 15.8 10.3 Add back current portion of finance leases 2.7 1.6 Add back current portion of plant closure provisions 5.2 6.7 Add back current portion of deferred income 0.1 0.1 Adjusted working capital $245.4 $179.4 During 2017 our working capital increased by $41.9 million, while our adjusted working capital has increased by $66.0 million. Thedifference is primarily due to the exclusion of cash and cash equivalents and long term debt from the adjusted working capitalmeasure. The Huntsman acquisition accounted for approximately $34.0 million of these movements which 42Table of Contentsincluded a one-off working capital funding requirement post acquisition, reflecting the structure of the acquisition, which excludedthe transfer of trade receivables and payables. The remaining movements are primarily driven by the timing of demand from ourcustomers. We had a $90.1 million increase in trade and other accounts receivable primarily related to a $61.9 million increase for the Huntsmanacquisition in our Performance Chemicals segment. The increase in sales in our Fuel Specialties and Oilfield Services segments hasalso increased receivables balances. Days’ sales outstanding in our Fuel Specialties segment increased from 46 days to 51 days;increased in our Performance Chemicals segment from 55 days to 68 days; and increased from 54 days to 58 days in our OilfieldServices segment. We had a $36.0 million increase in inventories, which is primarily related to a $23.4 million increase in our Fuel Specialties segmentdue to the timing of demand from customers. Days’ sales in inventory in our Fuel Specialties segment increased from 84 days to 100days; decreased in our Performance Chemicals segment from 94 days to 51 days; and decreased from 72 days to 63 days in ourOilfield Services segment. Prepaid expenses increased $6.9 million, from $6.2 million to $13.1 million, driven by a payment in advance of $4.2 million in ourSouth American business, together with the timing of invoices received and the normal expensing of prepaid invoices. We had a $67.0 million increase in accounts payable and accrued liabilities primarily related to a $37.1 million increase for theHuntsman acquisition in our Performance Chemicals segment and a $22.1 million increase for our Oilfield Services segment drivenby increased customer activity. Creditor days in our Fuel Specialties segment increased from 28 days to 32 days; in our PerformanceChemicals segment increased from 32 days to 50 days; and increased from 32 days to 51 days in our Oilfield Services segment. Operating Cash Flows We generated cash from operating activities of $82.7 million in 2017 compared to $105.5 million in 2016. Year over year cash fromoperating activities has been adversely impacted by the one-off working capital funding requirement of $28.0 million for theHuntsman acquisition. Cash At December 31, 2017 and 2016, we had cash and cash equivalents of $90.2 million and $101.9 million, respectively, of which$74.1 million and $90.2 million, respectively, were held by non-U.S. subsidiaries principally in the United Kingdom. The Companyis in a position to control whether or not to repatriate foreign earnings and we currently do not expect to make a repatriation in theforeseeable future. The Tax Reform Act requires, amongst other provisions, a one-time mandatory transition tax on accumulatedforeign earnings, for which we have recorded a provisional estimated tax liability at December 31, 2017 of $47.7 million. We intendto pay the tax liability over an eight-year payment schedule as prescribed by the Tax Reform Act. 43Table of ContentsDebt On December 14, 2016, Innospec and certain subsidiaries of the Company entered into a Third Amendment and RestatementAgreement with various lenders which amends and restates the Company’s credit facility agreement dated December 14, 2011, asamended and restated on August 28, 2013 and November 6, 2015 (the “Pre-Existing Credit Agreement;” the Pre-Existing CreditAgreement, as amended and restated pursuant to the Third Amendment and Restatement Agreement, being the “Amended CreditAgreement.”) The Amended Credit Agreement retains the $200,000,000 revolving credit facility available to the Company and adds a term loanfacility of $110,000,000. The termination date of the revolving facility remains November 6, 2020. A repayment for the term loan of$11,000,000 was made on December 29, 2017, to be followed by a $16,500,000 installment due December 28, 2018 and a$22,000,000 installment due December 28, 2019, with the outstanding balance due on November 6, 2020. The term loan and 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 debtto EBITDA must not be greater than 3.0:1 and (2) our ratio of EBITDA to net interest must not be less than 4.0:1. Management hasdetermined that the Company has not breached these covenants throughout the period to December 31, 2017 and does not expect tobreach these covenants for the next 12 months. The credit facility is secured by a number of fixed and floating charges over certainassets which include key operating sites of the Company and its subsidiaries. The current credit facility contains restrictions which may limit our activities, and operational and financial flexibility. We may notbe able to borrow if an event of default is outstanding, which includes a material adverse change to our assets, operations or financialcondition. The credit facility contains a number of restrictions that limit our ability, among other things, and subject to certain limitedexceptions, 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, 2017, we had $121.0 million of debt outstanding under the revolving credit facility, $99.0 million of debtoutstanding on our term loan and $5.9 million of obligations under finance leases relating to certain fixed assets within our FuelSpecialties and Oilfield Services segments. 44Table of ContentsAt December 31, 2017, our maturity profile of long-term debt and finance leases is set out below: (in millions) 2018 $18.5 2019 22.9 2020 182.5 2021 0.4 Total debt 224.3 Current portion of long-term debt and finance leases (18.5) Long-term debt and finance leases, net of current portion $205.8 The fair value of long-term debt approximates to the carrying value, as the discounting to its present value is offset by the interestrate swaps. Outlook Our business has performed well in 2017, and this is reflected in our positive results. This is continued evidence that our strategy isworking. Delivering new products to customers in our key markets, combined with good customer service has enabled us to meet ourexpectations, in spite of some very challenging market conditions. The business has continued to generate good cash flows even inthe light of the required working capital investments to grow and integrate the acquired business, and our leverage has been furtherimproved. We continue to have expectations that our Fuel Specialties, Performance Chemicals and Oilfield Services businesses will delivergood performances in 2018. We expect to continue to focus on the development of new technology, combined with good customer service, in order to maintainour competitive advantage. We anticipate a decline in revenues from our Octane Additives segment. We have not agreed a new contract with our sole remainingcustomer and thus have limited visibility for 2018 and beyond. At December 31, 2017, the Company had cash and cash equivalents of $90.2 million, long-term debt of $218.4 million and financeleases of $5.9 million, giving total debt of $224.3 million, resulting in a net debt position of $134.1 million. During 2017 the Company did not repurchase any of our common stock under the authorized share repurchase program announcedon November 3, 2015. The Company expects to fund its operations and share repurchase program over at least the next 12 months from a combination ofoperating cash flows and its revolving credit facility. 45Table of ContentsContractual Commitments The following represents contractual commitments at December 31, 2017 and the effect of those obligations on future cash flows: (in millions) Total 2018 2019-20 2021-22 Thereafter Operating activities Planned funding of pension obligations $5.2 $1.0 $2.1 $2.1 $0.0 Remediation payments 46.1 5.2 8.5 5.0 27.4 Operating lease commitments 20.3 4.3 6.3 3.8 5.9 Raw material purchase obligations 19.8 6.4 8.2 3.4 1.8 Interest payments on debt 11.5 4.8 6.7 0.0 0.0 Investing activities Capital commitments 2.3 2.3 0.0 0.0 0.0 Financing activities Long-term debt obligations 218.4 15.7 202.7 0.0 0.0 Finance leases 5.9 2.7 2.6 0.6 0.0 Total $329.5 $42.4 $237.1 $14.9 $35.1 Operating activities The amounts related to pension obligations refer to the likely levels of funding of our United Kingdom defined benefit pension plan(the “Plan”). The Plan is closed to future service accrual, but has a large number of deferred and current pensioners. The Companyexpects its annual cash contribution to be $1.0 million in 2018, $2.1 million in 2019-20 and $2.1 million in 2021-22. It is notconsidered meaningful to predict amounts beyond 2022 since there are too many uncertainties including future returns on assets,pension increases and inflation which are evaluated when the plan undertakes an actuarial valuation every three years. Remediation payments represent those cash flows that the Company is currently obligated to pay in respect of environmentalremediation of current and former facilities. It does not include any discretionary remediation costs that the Company may choose toincur. Operating lease commitments relate primarily to office space, motor vehicles and various items of computer and office equipmentwhich are expected to be renewed and replaced in the normal course of business. Raw material purchase obligations relate to certain long-term raw material contracts which stipulate fixed or minimum quantities tobe purchased; fixed, minimum or variable cost provisions; and the approximate timing of the transaction. Purchase obligationsexclude agreements that are cancelable without penalty. 46Table of ContentsThe estimated payments included in the table above reflect the variable interest charge on long-term debt obligations. Estimatedcommitment fees are also included and interest income is excluded. Due to the uncertainty regarding the nature of tax audits, particularly those which are not currently underway, it is not meaningful topredict the outcome of obligations related to unrecognized tax benefits. Further disclosure is provided in Note 10 of the Notes to theConsolidated Financial Statements. Investing activities Capital commitments relate to certain capital projects that the Company has committed to undertake. Financing activities On December 14, 2016, Innospec and certain subsidiaries of the Company entered into a Third Amendment and RestatementAgreement with various lenders which amends and restates the Company’s credit facility agreement dated December 14, 2011, asamended and restated on August 28, 2013 and November 6, 2015 (the “Pre-Existing Credit Agreement” the Pre-Existing CreditAgreement, as amended and restated pursuant to the Third Amendment and Restatement Agreement, being the “Amended CreditAgreement.”) The Amended Credit Agreement retains the $200,000,000 revolving credit facility available to the Company and adds a term loanfacility of $110,000,000. The termination date of the revolving facility remains November 6, 2020. A repayment for the term loan of$11,000,000 was made on December 29, 2017, to be followed by a $16,500,000 installment due December 28, 2018 and a$22,000,000 installment due December 28, 2019, with the outstanding balance due on November 6, 2020. Finance leases relate to the financing of certain fixed assets in our Fuel Specialties and Oilfield Services segments. Environmental Matters and Plant Closures Under certain environmental laws the Company is responsible for the remediation of hazardous substances or wastes at currently orformerly owned or operated properties. As most of our manufacturing operations have been conducted outside the U.S., we expect that liability pertaining to theinvestigation and remediation of contaminated properties is likely to be determined under non-U.S. law. We evaluate costs for remediation, decontamination and demolition projects on a regular basis. Full provision is made for those coststo which we are committed under environmental laws amounting to $46.1 million at December 31, 2017. Remediation expenditureutilizing these provisions was $2.4 million, $2.7 million and $2.6 million in the years 2017, 2016 and 2015, respectively. 47Table of ContentsItem 7AQuantitative 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 interestrates and foreign currency exchange rates. The political and economic risks are mitigated by the stability of the countries in whichthe Company’s largest operations are located. Credit limits, ongoing credit evaluation and account monitoring procedures are used tominimize 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 forwardexchange contracts, in the normal course of business to manage market risks. The derivatives used in hedging activities areconsidered risk management tools and are not used for trading purposes. In addition, the Company enters into derivative instrumentswith a diversified group of major financial institutions in order to manage the exposure to non-performance of such instruments. TheCompany’s objective in managing the exposure to changes in interest rates is to limit the impact of such changes on earnings andcash flows and to lower overall borrowing costs. The Company’s objective in managing the exposure to changes in foreign currencyexchange 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 tovariability the Company may use commodity swaps to hedge the cost of some raw materials thus reducing volatility on earnings andcash flows. The derivatives are considered risk management tools and are not used for trading purposes. The Company’s objective isto 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. As at December 31, 2017 the Companyhad cash and cash equivalents of $90.2 million, and long-term debt and finance leases of $224.3 million (including current portion).Long-term debt comprises a $200,000,000 revolving credit facility available to the Company and a remaining term loan facility of$99,000,000. The credit facilities carry an interest rate based on U.S. dollar LIBOR plus a margin of between 1.20% and 2.45%which is dependent on the Company’s ratio of net debt to EBITDA. Net debt and EBITDA are non-GAAP measures of liquiditydefined in the credit facility. At December 31, 2017, $121.0 million was drawn under the revolving credit facility and the term loanfacility of $99.0 million was drawn. A repayment for the term loan of $11,000,000 was made on December 29, 2017, to be followedby a $16,500,000 installment due December 28, 2018 and a $22,000,000 installment due December 28, 2019, with the outstandingbalance due on November 6, 2020. The Company has taken out interest rate swaps to hedge interest rate risk on core debt. As at December 31, 2017, interest rate swapswith a notional value of $149,000,000 were in place. Fixed interest rates payable under the interest rate swaps vary from 1.42% to1.67%. Interest 48Table of Contentsrate swaps in place to hedge interest rate risk on the term loan have an amortizing profile matching the amortization of the term loan. The Company has $224.3 million long-term debt and finance leases (including the current portion) which is partly offset by$90.2 million cash and cash equivalents. The interest payable on long-term debt (excluding the margin) exceeds the interestreceivable on positive cash balances. On a gross basis, assuming no additional interest on the cash balances and after deductinginterest rate hedging, a hypothetical absolute change of 1% in U.S. base interest rates for a one-year period would impact net incomeand cash flows by approximately $0.7 million before tax. On a net basis, assuming additional interest on the cash balances, ahypothetical absolute change of 1% in U.S. base interest rates for a one-year period would impact net income and cash flows byapproximately $0.2 million before tax. The above does not consider the effect of interest or exchange rate changes on overall activity nor management action to mitigatesuch changes. As at December 31, 2017, Innospec has interest rate swaps which mitigate a proportion of the risk identified above. Exchange Rate Risk The Company generates an element of its revenues and incurs some operating costs in currencies other than the U.S. dollar. Thereporting 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 thenature of the markets in which they operate. In addition, the financial position and results of operations of some of our overseassubsidiaries are reported in the relevant local currency and then translated to U.S. dollars at the applicable currency exchange rate forinclusion in our consolidated financial statements. The primary foreign currencies in which we have exchange rate fluctuation exposure are the European Union euro, British poundsterling and Brazilian Real. Changes in exchange rates between these foreign currencies and the U.S. dollar will affect the recordedlevels of our assets and liabilities, to the extent that such figures reflect the inclusion of foreign assets and liabilities which aretranslated 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 volatilityassociated with foreign currency exchange rate changes. Accordingly, the Company enters into various contracts that change in valueas 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 ofthe Company’s exposure to certain foreign currency denominated revenues so that gains and losses on these 49Table of Contentscontracts offset changes in the U.S. dollar value of the related foreign currency denominated revenues. The objective of the hedgingprogram is to reduce earnings and cash flow volatility related to changes in foreign currency exchange rates. The trading of our Fuel Specialties, Performance Chemicals and Oilfield Services segments is inherently naturally hedged andaccordingly changes in exchange rates would not be material to our earnings or financial position. The cost base of our OctaneAdditives reporting segment and corporate costs, however, are largely denominated in British pound sterling. A 5% strengthening inthe U.S. dollar against British pound sterling would increase reported operating income by approximately $2.8 million for aone-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 theopposite effect on operating income. Raw Material Cost Risk We use a variety of raw materials, chemicals and energy in our manufacturing and blending processes. Many of the raw materialsthat we use are derived from petrochemical-based and vegetable-based feedstocks which can be subject to periods of rapid andsignificant cost instability. These fluctuations in cost can be caused by political instability in oil producing nations and elsewhere, orother factors influencing global supply and demand of these materials, over which we have no or little control. We use long-termcontracts (generally with fixed or formula-based costs) and advance bulk purchases to help ensure availability and continuity ofsupply, and to manage the risk of cost increases. From time to time we enter into hedging arrangements for certain raw materials, butdo 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 andcash flows from operating activities would be adversely impacted. Should raw material costs increase significantly, then theCompany’s need for working capital could similarly increase. Any of these risks could adversely impact our results of operations,financial position and cash flows. 50Table of ContentsItem 8Financial Statements and Supplementary Data Report of IndependentRegistered Public Accounting Firm To the stockholders and board of directorsInnospec Inc.: Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting We have audited the accompanying consolidated balance sheets of Innospec Inc. and subsidiaries (the “Company”) as ofDecember 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, accumulated othercomprehensive loss, cash flows, and equity for each of the years in the three-year period ended December 31, 2017, and the relatednotes (collectively, the “consolidated financial statements”). We also have audited the Company’s internal control over financialreporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework ( 2013 ) issued by theCommittee of Sponsoring Organizations of the Treadway Commission. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position ofthe Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles. Also in our opinion, theCompany maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based oncriteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of theTreadway Commission. Basis for Opinion The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal controlover financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in theaccompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion onthe Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based onour 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 andthe 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 theaudits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whetherdue to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. 51Table of ContentsOur audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of theconsolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Suchprocedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financialstatements. Our audits also included evaluating the accounting principles used and significant estimates made by management, aswell as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financialreporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weaknessexists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits alsoincluded performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide areasonable 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 reliabilityof financial reporting and the preparation of financial statements for external purposes in accordance with generally acceptedaccounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain tothe maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of thecompany; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statementsin accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made onlyin accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regardingprevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a materialeffect 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 becauseof changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ KPMG Audit Plc We have served as the Company’s auditor since 2011.

Our Performance Chemicals business provides effective technology-based solutions for ourcustomers’ processes or products focused in the Personal Care, Home Care, Agrochemical and Mining markets. Our OctaneAdditives business manufactures a fuel additive for use in automotive gasoline and provides services in respect of environmentalremediation. Our principal reportable segments are Fuel Specialties, Performance Chemicals, Oilfield Services and OctaneAdditives. Note 2. Accounting Policies Basis of preparation: The consolidated financial statements have been prepared in accordance with generally accepted accountingprinciples (“GAAP”) in the United States of America on a going concern basis and include all subsidiaries of the Company wherethe Company has a controlling financial interest. All significant intercompany accounts and balances have been eliminated uponconsolidation. In accordance with GAAP in the United States of America, the results of operations of an acquired or disposedbusiness 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 ofAmerica, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financialstatements and accompanying notes. Actual results could differ from those estimates. Cash equivalents: Investment securities with maturities of three months or less when purchased are considered to be cashequivalents. Trade and other accounts receivable: The Company records trade and other accounts receivable at net realizable value and maintainsallowances for customers not making required payments. The Company determines the adequacy of allowances by periodicallyevaluating each customer receivable considering our customer’s financial condition, credit history and current economic conditions. Inventories: Inventories are stated at the lower of cost (FIFO method) or market value. Cost includes materials, labor and anappropriate proportion of plant overheads. The Company accrues volume discounts where it is probable that the required volume willbe attained and the amount can be reasonably estimated. The discounts are recorded as a reduction in the cost 58Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) of materials based on projected purchases over the period of the agreement. Inventories are adjusted for estimated obsolescence andwritten 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 isprovided over the estimated useful lives of the assets using the straight-line method and is allocated between cost of goods sold andoperating expenses. The cost of additions and improvements are capitalized. Maintenance and repairs are charged to expenses asincurred. When assets are sold or retired the associated cost and accumulated depreciation are removed from the consolidatedfinancial statements and any related gain or loss is included in earnings. The estimated useful lives of the major classes ofdepreciable assets are as follows: Buildings 7 to 25 years Equipment 3 to 10 years Goodwill and other intangible assets: Goodwill and other intangible assets deemed to have indefinite lives are subject to at leastannual impairment assessments. Initially we perform a qualitative assessment to determine whether it is more likely than not that thefair value of a segment is less than the carrying amount prior to performing the two-step goodwill impairment test. If a two-step testis required we assess the fair value based on projected post-tax cash flows discounted at the Company’s weighted average cost ofcapital. The annual measurement date for impairment assessment of the goodwill relating to the Fuel Specialties, PerformanceChemicals and Oilfield Services segments is December 31 each year. The Company capitalizes software development costs,including licenses, subsequent to the establishment of technological feasibility. Other intangible assets deemed to have finite lives,including software development costs and licenses, are amortized using the straight-line method over their estimated useful lives andtested for any potential impairment when events occur or circumstances change which suggest that an impairment may haveoccurred. Deferred finance costs: The costs relating to debt financing are capitalized, offset against long-term debt in the consolidated balancesheets and amortized using the effective interest method over the expected life of the debt financing facility. See Note 11 of theNotes to the Consolidated Financial Statements. Impairment of long-lived assets: The Company reviews the carrying value of its long-lived assets, including buildings andequipment, whenever changes in circumstances suggest that the carrying values may be impaired. In order to facilitate this test theCompany groups together assets at the lowest possible level for which cash flow information is available. Undiscounted future cashflows expected to result from the asset groups are compared with the carrying value of the asset groups and if they are lower animpairment loss may be recognized. The amount of the impairment loss is the difference between the fair value and 59Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) the carrying value of the asset groups. Fair values are determined using post-tax cash flows discounted at the Company’s weightedaverage 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 theCompany’s corporate risk management policy to minimize exposure and are not for speculative trading purposes. The Companyrecognizes all derivatives as either current or non-current assets or liabilities in the consolidated balance sheet and measures thoseinstruments at fair value. Changes in the fair value of derivatives that are not designated as hedges, or do not meet the requirementsfor hedge accounting, are recognized in earnings. Derivatives which are designated as hedges are tested for effectiveness on aquarterly basis, and marked to market. The ineffective portion of the derivative’s change in value is recognized in earnings. Theeffective portion is recognized in other comprehensive income until the hedged item is recognized in earnings. Environmental compliance and remediation: Environmental compliance costs include ongoing maintenance, monitoring and similarcosts. We recognize environmental liabilities when they are probable and the costs can be reasonably estimated, and asset retirementobligations when there is a legal obligation and the costs can be reasonably estimated. Such accruals are adjusted as furtherinformation develops or circumstances change. Costs of future obligations are discounted to their present values using theCompany’s historic credit-adjusted risk-free rate. Revenue recognition: The Company supplies products to customers from its various manufacturing sites and in some instances fromcontainers held on customer sites, under a variety of standard shipping terms and conditions. In each case revenue is recognizedwhen legal title, which is defined and generally accepted in the standard terms and conditions, and the risk of loss transfers betweenthe Company and the customer. Provisions for sales discounts and rebates to customers are based upon the terms of sales contractsand are recorded in the same period as the related sales as a deduction from revenue. The Company accounts for an estimate of theprovision required for sales discounts and rebates based on the terms of each agreement at the time of revenue recognition. Components of net sales: All amounts billed to customers relating to shipping and handling are classified as net sales. Shipping andhandling 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 andnon-recoverable taxes, inbound handling costs associated with the receipt of raw materials, packaging materials, manufacturing costsincluding labor costs, maintenance and utility costs, plant and engineering overheads, amortization expense for certain otherintangible assets, warehousing and outbound shipping costs and handling costs. Inventory losses and provisions and the costs ofcustomer claims are also recognized in the cost of goods line item. 60Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Components of selling, general and administrative expenses: Selling expenses comprise the costs of the direct sales force, and thesales management and customer service departments required to support them. It also comprises commission charges, the costs ofsales 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 includingaccounting, 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 litigationin 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 theperiod. 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 ofentities that have functional currencies other than the U.S. dollar are taken to a separate equity reserve, the cumulative translationadjustment. In entities where the U.S. dollar is the functional currency no gains or losses on translation occur, and gains or losses onmonetary 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 settlein the foreseeable future, are also recorded in accumulated other comprehensive loss. Other foreign exchange gains or losses are alsoincluded in other income, net in the income statement. Stock-based compensation plans: The Company accounts for employee stock options and stock equivalent units under the fair valuemethod. Stock options are fair valued at the grant date and the fair value is recognized straight-line over the vesting period of theoption. Stock equivalent units are fair valued at each balance sheet date and the fair value is spread over the remaining vesting periodof the unit. Pension plans and other post-employment benefits: The Company recognizes the funded status of defined benefit post-retirementplans on the consolidated balance sheets and changes in the funded status in comprehensive income. The measurement date of theplan’s funded status is the same as the Company’s fiscal year-end. The service costs are recognized as employees render the servicesnecessary to earn the post-employment benefits. Prior service costs and credits and actuarial gains and losses are amortized over theaverage remaining life expectancy of the inactive participants using the corridor method. 61Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Income taxes: The Company provides for income taxes by recognizing deferred tax assets and liabilities for the expected future taxconsequences of temporary differences between the financial statement carrying amounts and the relevant tax bases of the assets andliabilities. Then the Company evaluates the need for a valuation allowance to reduce deferred tax assets to the amount more likelythan not to be realized. The effect on deferred taxes of a change in tax rates is recognized in the period that includes the enactmentdate. The Company recognizes the tax benefit from a tax position only if it is more likely than not the tax position will be sustainedon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financialstatements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of beingrealized 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 ourconsolidated statements of income. Note 3. Segment Reporting and Geographical Area Data The Fuel Specialties, Performance Chemicals and Oilfield Services segments operate in markets where we actively seek growthopportunities although their ultimate customers are different. The Octane Additives segment is expected to decline in the near futureas our one remaining refinery customer transitions to unleaded fuel. Our Fuel Specialties segment develops, manufactures, blends, markets and supplies a range of specialty chemicals products used asadditives to a wide range of fuels. Our Performance Chemicals segment provides effective technology-based solutions for our customers’ processes or products focusedin the Personal Care, Home Care, Agrochemical and Mining markets. Our Oilfield Services segment develops and markets products to prevent loss of mud in drilling operations, chemical solutions forfracturing and stimulation operations and products for oil and gas production which aid flow assurance and asset integrity. Our Octane Additives segment, which we believe is the world’s only producer of tetra ethyl lead (“TEL”), comprises sales of TELfor use in automotive gasoline and provides services in respect of environmental remediation. There are no significant customers with sales greater than 10% of our net group sales in the last three financial years. 62Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The Company evaluates the performance of its segments based on operating income.

Acquisition of European Differentiated Surfactants business On December 30, 2016, the Company acquired the European Differentiated Surfactants business (“Huntsman”) from HuntsmanInvestments (Netherlands) B.V.. We purchased the business for a total consideration of $200.2 million. We acquired the business inorder to continue our strategy of building our presence in the Personal Care and Home Care markets which form part of ourPerformance Chemicals segment. During the year we have reviewed the fair values of assets acquired and liabilities assumed based on information becoming availableafter our previous filing, resulting in a $23.1 million increase in assets acquired and a corresponding decrease in goodwill in relationto the recognition of customer relationships offset by an increase in deferred taxation liabilities. The final working capitaladjustments of $2.6 million were agreed in the third quarter of 2017. Huntsman, and the associated goodwill, are included within our Performance Chemicals segment for management and reportingpurposes. There is currently no goodwill amortizable for tax purposes. Note 5. Earnings per Share Basic earnings per share is based on the weighted average number of common shares outstanding during the period. Diluted earningsper share includes the effect of options that are dilutive and outstanding during the period. Per share amounts are computed asfollows: 2017 2016 2015 Numerator (in millions): Net income available to common stockholders $61.8 $81.3 $119.5 Denominator (in thousands): Weighted average common shares outstanding 24,148 23,998 24,107 Dilutive effect of stock options and awards 338 444 505 Denominator for diluted earnings per share 24,486 24,442 24,612 Net income per share, basic: $2.56 $3.39 $4.96 Net income per share, diluted: $2.52 $3.33 $4.86 In 2017, 2016 and 2015 the average number of anti-dilutive options excluded from the calculation of diluted earnings per share were9,422, 0 and 0 respectively. 66Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Note 6.

Of the total net book value of equipment at December 31, 2017 $6.2 million (2016 – $4.4 million) are in respect of assets held underfinance leases. Depreciation charges were $21.4 million, $13.5 million and $13.0 million in 2017, 2016 and 2015, respectively. The estimated additional cost to complete work in progress is $2.3 million (2016 – $9.5 million). 67Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Note 7.

During the year we have reviewed the fair values of assets acquired and liabilities assumed for our Huntsman acquisition within ourPerformance Chemicals segment, based on information becoming available after our previous filing, resulting in a $23.1 millionincrease in assets acquired and a corresponding decrease in goodwill. The Company’s reporting units, the level at which goodwill is tested for impairment, are consistent with the reportable segments:Fuel Specialties, Performance Chemicals, Oilfield Services and Octane Additives. The components in each segment (includingproducts, markets and competitors) have similar economic characteristics and the segments, therefore, reflect the lowest level atwhich operations and cash flows can be clearly distinguished, operationally and for financial reporting purposes, from the rest of theCompany. The Company assesses goodwill for impairment on at least an annual basis, initially based on a qualitative assessment to determinewhether it is more likely than not that the fair value of a segment is less than the carrying amount. If a potential impairment isidentified then a two-step impairment test is followed. 68(1)(1)(1)Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The Company performed its annual impairment assessment in respect of goodwill as at December 31, 2017, 2016 and 2015. Ourimpairment assessment concluded that there had been no impairment of goodwill in respect of those reporting units.

Pension and Post-employment Benefits United Kingdom plan The Company maintains a defined benefit pension plan (the “Plan”) covering a number of its current and former employees in theUnited Kingdom, although it does also have other much smaller pension arrangements in the U.S. and overseas. The Plan is closed tofuture service accrual but has a large number of deferred and current pensioners. The Projected Benefit Obligation (“PBO”) is basedon final salary and years of credited service reduced by social security benefits according to a plan formula. Normal retirement age is65 but provisions are made for early retirement. The Plan’s assets are invested by several investment management companies infunds holding United Kingdom and overseas equities, United Kingdom and overseas fixed interest securities, index linked securities,property unit trusts and cash or cash equivalents. The trustees’ investment policy is to seek to achieve specified objectives throughinvesting in a suitable mixture of real and monetary assets. The trustees recognize that the returns on real assets, while expected to begreater over the long-term than those on monetary assets, are likely to be more volatile. A mixture across asset classes shouldnevertheless provide the level of returns required by the Plan to meet its liabilities at an acceptable level of risk for the trustees andan acceptable level of cost to the Company. In 2017, the Company contributed $1.0 million in cash to the Plan in accordance with an agreement with the trustees. 73Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) (in millions) 2017 2016 2015 Plan net pension (credit)/charge: Service cost $0.9 $1.0 $1.5 Interest cost on PBO 15.2 20.7 27.7 Expected return on plan assets (24.5) (29.9) (33.4) Amortization of prior service credit (1.0) (1.1) (1.2) Amortization of actuarial net losses 5.0 2.6 5.2 $(4.4) $(6.7) $(0.2) Plan assumptions at December 31, (%): Discount rate 2.56 2.48 3.69 Inflation rate 2.20 2.25 2.15 Rate of return on plan assets – overall on bid-value 2.75 3.20 4.20 Plan asset allocation by category (%): Equity securities 38 25 34 Debt securities 53 66 62 Cash 9 9 4 100 100 100 The discount rate used represents the annualized yield based on a cash flow matched methodology with reference to an AA corporatebond spot curve and having regard to the duration of the Plan’s liabilities. The inflation rate is derived using a similar cash flowmatched methodology as used for the discount rate but having regard to the difference between yields on fixed interest and indexlinked United Kingdom government gilts. A 0.25% change in the discount rate assumption would change the PBO by approximately$25 million and the net pension credit for 2017 would change by approximately $0.1 million. A 0.25% change in the level of priceinflation assumption would change the PBO by approximately $18 million and the net pension credit for 2017 by approximately$1.5 million. The current investment strategy of the Plan is to obtain an asset allocation of approximately 85% debt securities and 15% equitysecurities in order to achieve a more predictable return on assets. As at December 31, 2017, approximately 30% (December 31, 2016– 37%) of the Plan’s assets were held in index-tracking funds with one investment management company. Approximately 10%(December 31, 2016 – 18%) of the Plan’s assets were invested in United Kingdom government gilts. No more than 5% of the Plan’sassets were invested in any one individual company’s investment funds. 74Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Movements in PBO and fair value of Plan assets are as follows: (in millions) 2017 2016 Change in PBO: Opening balance $710.2 $739.7 Interest cost 15.2 20.7 Service cost 0.9 1.0 Benefits paid (37.8) (39.7) Actuarial losses/(gains) (32.7) 119.8 Exchange effect 65.6 (131.3) Closing balance $721.4 $710.2 Fair value of plan assets: Opening balance $758.2 $795.2 Actual benefits paid (37.8) (39.7) Actual contributions by employer 1.0 1.1 Actual return on assets 43.0 142.2 Exchange effect 73.0 (140.6) Closing balance $837.4 $758.2 The accumulated benefit obligation for the Plan was $721.4 million and $710.2 million at December 31, 2017 and 2016,respectively. For the vast majority of assets, a market approach is adopted to assess the fair value of the assets, with the inputs being the quotedmarket prices for the actual securities held in the relevant fund. Equity securities Common and preferred stock for which market prices are readily available at the measurement date are valued at the last reportedsale price or official closing price on the primary market or exchange on which they are actively traded and are classified in Level 1. Fixed income securities Fixed income securities are valued based on quotations received from independent pricing services or from dealers who makemarkets in such securities and are classified as Level 1. Insurance contracts The Company has invested in insurance contracts, known as buy-in contracts. The value of the insurance contract is based onsignificant unobservable inputs including plan participant medical data, in addition to observable inputs which include expectedreturn on assets and 75Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) estimated value premium. Therefore we have classified the contracts as Level 3 investments. Fair value estimates are provided by theexternal parties and are subsequently reviewed and approved by management.

Income Taxes A roll-forward of unrecognized tax benefits is as follows: (in millions) 2017 2016 2015 Opening balance at January 1 $2.2 $3.6 $5.7 Reductions for tax positions of prior periods 0.0 (0.6) 0.0 Additions for tax positions of prior periods 0.5 0.0 0.3 Additions for current year tax positions 0.0 0.0 1.2 Reductions due to lapsed statute of limitations (0.5) (0.8) (3.6) Closing balance at 31 December $2.2 $2.2 $3.6 We recognize accrued interest and penalties associated with unrecognized tax benefits as part of income taxes in our consolidatedstatements of income. Related to the unrecognized tax benefits noted above, we accrued net interest and penalties of $0.2 millionduring 2017, a net reduction in interest and penalties of $0.2 million in 2016 and a net reduction in interest and penalties of $0.2million in 2015. Total accrued interest and penalties at December 31, 2017 on all remaining unrecognized tax benefits amounted to$0.3 million (December 31, 2016 - $0.1 million). All of the $2.5 million of unrecognized tax benefits, and interest and penalties, would impact our effective tax rate if recognized. The Company or one of its subsidiaries files income tax returns with the U.S. federal government, and various state and foreignjurisdictions. As previously disclosed, one of the Company’s U.S. subsidiaries was subject to a state tax examination in respect of2012 through to 2014 inclusive. The examination was completed in the fourth quarter of 2017 at no additional cost to the Company. The Company and its U.S. subsidiaries are currently subject to a federal income tax examination in respect of 2015. The Companycurrently anticipates that adjustments, if any, arising out of this tax audit would not result in a material change to the Company’sfinancial position as at December 31, 2017. As previously disclosed, tax audits have been opened by the Italian tax authorities in respect of Innospec Performance ChemicalsItalia Srl, acquired as part of the Huntsman business in respect of the period 2011 to 2013 inclusive. As a consequence of informationreceived in the fourth quarter of 2017, the Company believes that additional tax of approximately $0.5 million, together withassociated interest of $0.2 million, may arise as a result of the 2011 audit. There is insufficient evidence to conclude on the positionin relation to 2012 or 2013 at the current time. As any additional tax arising as a consequence of the tax audit would be reimbursedby the previous owner under the terms of the sale and purchase agreement, the Company has recorded an unrecognized tax benefit of$0.7 million in the quarter, 79Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) together with an indemnification asset of the same amount to reflect the fact that the final liability would be reimbursed by theprevious owner. The Company and its U.S. subsidiaries remain open to examination by the IRS for years 2014 onwards. The Company’s subsidiariesin foreign tax jurisdictions are open to examination including France (2014 onwards), Germany (2015 onwards), Switzerland (2015onwards) and the United Kingdom (2016 onwards). The sources of income before income taxes were as follows: (in millions) 2017 2016 2015 Domestic $3.1 $16.8 $52.7 Foreign 125.0 86.3 99.6 $128.1 $103.1 $152.3 The components of income tax expense are summarized as follows: (in millions) 2017 2016 2015 Current: Federal $51.2 $4.4 $5.2 State and local 0.9 1.1 1.3 Foreign 21.0 15.3 14.3 73.1 20.8 20.8 Deferred: Federal (8.1) (0.7) 12.8 State and local 0.7 (0.3) 0.5 Foreign 0.6 2.0 (1.3) (6.8) 1.0 12.0 $66.3 $21.8 $32.8 Cash payments for income taxes were $24.2 million, $23.1 million and $22.5 million during 2017, 2016 and 2015, respectively. 80Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The effective tax rate varies from the U.S. federal statutory rate because of the factors indicated below: (in percent) 2017 2016 2015 Statutory rate 35.0% 35.0% 35.0% Foreign income inclusions 2.1 1.0 1.8 Foreign tax rate differential (13.7) (16.6) (9.6) Tax charge/(credit) from previous years 1.1 (0.7) (0.5) Net credit from unrecognized tax benefits (0.4) (1.6) (1.5) Foreign currency transactions (0.9) 2.4 (1.9) United Kingdom income tax rate reduction 0.0 (0.6) (0.7) Effect of U.S. tax law change 31.7 0.0 0.0 Other items and adjustments, net (3.1) 2.2 (1.1) 51.8% 21.1% 21.5% The most significant factor impacting our effective tax rate is the recognized implications of the Tax Reform Act. U.S. GAAPrequires that the impact of tax legislation is recognized in the period in which the law was enacted. In December 2017, the SEC staffissued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax ReformAct. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Reform Act enactment date forcompanies to complete their accounting under ASC 740, Income Taxes . Until accounting is complete, companies may recordprovisional estimates. As a result of the Tax Reform Act, we accrued a provisional estimate of the mandatory transition tax on our accumulated earnings asof December 31, 2017, resulting in an increase to income tax expense of $47.7 million. In addition, our U.S. deferred tax assets andliabilities were re-measured using a tax rate reduced from 35% to 21% at the same date, which resulted in $7.1 million of deferredincome tax benefit. On account of the complexity of the new Global Intangible Low-Taxed Income (“GILTI”) tax rules, the company continues toevaluate this provision of the Tax Reform Act and the application of ASC 740, Income Taxes . Under U.S. GAAP, the Company isallowed to make an accounting policy choice of either treating taxes due on future U.S. inclusions in taxable income related to GILTIas a current period expense when incurred (the “period cost method”) or factoring such amounts into the Company’s recognition andmeasurement of its deferred taxes (the “deferred method”). The Company has not yet made any adjustments related to potentialGILTI tax in its financial statements and has not yet made an accounting policy decision in respect of GILTI. We consider the accounting of the transition tax, GILTI provisions and other items to be incomplete due to the forthcoming guidanceand our ongoing analysis of final data and tax positions which may impact these calculations. 81Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) We expect to complete our analysis within the measurement period in accordance with SAB 118. The mix of taxable profits generated in the different geographical jurisdictions in which the Group operates continues to have asignificant positive impact on the effective rate. Foreign income inclusions arise each year from certain types of income earned overseas being taxable under the U.S. tax regulations.These types of income include Subpart F income, principally from foreign based company sales in the United Kingdom, includingthe associated Section 78 tax gross up, and also from the income earned by certain overseas subsidiaries taxable under the U.S. taxregime. Foreign income inclusions have a negative impact on the effective tax rate. Foreign tax credits can fully or partially offset these incremental U.S. taxes from foreign income inclusions. The utilization offoreign tax credits varies year on year as this is dependent on a number of variable factors which are difficult to predict and may incertain years prevent any offset of foreign tax credits. The effective rate is favorably impacted by the generation of foreign tax creditsagainst foreign income inclusions in 2017. Other items do not have a material impact on the effective tax rate. 82Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Details of deferred tax assets and liabilities are analyzed as follows: (in millions) 2017 2016 Deferred tax assets: Stock compensation $4.3 $5.5 Net operating loss carry forwards 15.9 18.2 Other intangible assets 4.8 3.7 Accretion expense 3.3 5.1 Other 4.5 9.5 Subtotal 32.8 42.0 Less valuation allowance 0.0 0.0 Total net deferred tax assets $32.8 $42.0 Deferred tax liabilities: Property, plant and equipment $(16.7) $(13.0) Intangible assets including goodwill (27.0) (38.0) Pension asset (18.3) (8.2) Investment impairment recapture (3.5) 0.0 Customer relationships (5.8) 0.0 Other 0.0 (0.2) Total deferred tax liabilities $(71.3) $(59.4) Net deferred tax liability $(38.5) $(17.4) Deferred tax assets $6.5 $14.9 Deferred tax liabilities (45.0) (32.3) $(38.5) $(17.4) The Tax Reform Act reduces the U.S. statutory corporate tax rate from 35% to 21%, effective January 1, 2018, which resulted in there-measurement of our U.S. deferred tax positions as of December 31, 2017. Consequently, we have recorded a decrease to our netdeferred tax liability of $7.1 million, with a corresponding net adjustment to deferred tax benefit of $7.1 million for the year endedDecember 31, 2017. The Company evaluates deferred tax assets to determine whether it is more likely than not that they will be realized. Deferred taxassets are reviewed each period on a tax jurisdiction by tax jurisdiction basis to analyze whether there is sufficient positive ornegative evidence to support realizability. As a result of the Company’s assessment of its deferred tax assets at December 31, 2017,the Company considers it more likely than not that it will recover the full benefit of its deferred tax assets and no valuation allowanceis required. Should it be determined in the future that it is no longer more likely than not that these assets will be realized, a valuation allowancewould be required, and the Company’s operating 83Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) results would be adversely affected during the period in which such a determination would be made. Gross net operating loss carry forwards of $75.2 million result in a deferred tax asset of $15.9 million. The net operating loss carryforwards arose in the U.S. and in five of the Company’s foreign subsidiaries. Net operating loss carry forwards of $27.1 millionarose from state and federal tax losses in prior and current periods in certain of the Company’s U.S. subsidiaries. It is expected thatsufficient taxable profits will be generated in the U.S. against which the federal net operating loss carry forwards of $16.6 millioncan be relieved prior to their expiration in the period 2035 to 2037, and the state net operating loss carry forwards of $10.5 millioncan be relieved before their expiration in the period 2022 to 2037. The net operating loss carry forwards in five of the Company’sforeign subsidiaries totaling $48.1 million arose in prior and current periods and it is expected that sufficient taxable profits will begenerated against which these net operating loss carry forwards can be relieved. These losses can be carried forward indefinitelywithout expiration. The Company is in a position to control whether or not to repatriate foreign earnings and we currently do not expect to make arepatriation in the foreseeable future. No additional income taxes have been provided for on any remaining undistributed foreignearnings not subject to the transition tax, or any additional outside basis difference inherent in these entities, as the earnings continueto be indefinitely reinvested in foreign operations. Determining the amount of unrecognized deferred tax liability related to anyremaining undistributed foreign earnings not subject to the transition tax and additional outside basis difference in these entities(i.e. basis difference in excess of that subject to the one-time transition tax) is not practicable at this time. Note 11. Long-Term Debt Long-term debt consists of the following: (in millions) 2017 2016 Revolving credit facility $121.0 $161.0 Term loan 99.0 110.0 Deferred finance costs (1.6) (2.2) 218.4 268.8 Less current portion (15.8) (10.3) $202.6 $258.5 On December 14, 2016, Innospec and certain subsidiaries of the Company entered into a Third Amendment and RestatementAgreement with various lenders which amends and restates the Company’s credit facility agreement dated December 14, 2011, asamended and restated on August 28, 2013 and November 6, 2015 (the “Pre-Existing Credit Agreement” the Pre-Existing CreditAgreement, as amended and restated pursuant to the Third Amendment and Restatement Agreement, being the “Amended CreditAgreement.”) 84Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The Amended Credit Agreement retains the $200,000,000 revolving credit facility available to the Company and adds a term loanfacility of $110,000,000. The termination date of the revolving facility remains November 6, 2020. A repayment for the term loan of$11,000,000 was made on December 29, 2017, to be followed by a $16,500,000 installment due December 28, 2018 and a$22,000,000 installment due December 28, 2019, with the outstanding balance due on November 6, 2020. The Company capitalized refinancing costs of $1.2 million in 2016, which are being amortized over the expected life of the facility,as shown here: (in millions) 2017 2016 Gross cost at January 1 $2.7 $1.5 Capitalized in the year 0.0 1.2 $2.7 $2.7 Accumulated amortization at January 1 $(0.5) $(0.1) Amortization in the year (0.6) (0.4) $(1.1) $(0.5) Net book value at December 31 $1.6 $2.2 Amortization expense was $0.6 million, $0.4 million and $1.2 million in 2017, 2016 and 2015, respectively. The charge is includedin interest expense, see Note 2 of the Notes to the Consolidated Financial Statements. The obligations of the Company under the credit facilities are secured obligations and guaranteed by certain subsidiaries of theCompany. Amounts available under the revolving facility may be borrowed in U.S. dollars, Euros, British pounds and other freelyconvertible currencies. The Company’s credit facilities contain restrictive clauses which may constrain our activities and limit our operational and financialflexibility. The facility obliges the lenders to comply with a request for utilization of finance unless there is an event of defaultoutstanding. Events of default are defined in the credit facility and include a material adverse change to our assets, operations orfinancial condition. The facility contains a number of restrictions that limit our ability, amongst other things, and subject to certainlimited exceptions, to incur additional indebtedness, pledge our assets as security, guarantee obligations of third parties, makeinvestments, undergo a merger or consolidation, dispose of assets, or materially change our line of business. In addition, the credit facilities contain 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 debtto EBITDA shall not be greater than 3.0:1 and (2) the ratio of EBITDA to net interest shall not be less than 85Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 4.0:1. Management has determined that the Company has not breached these covenants throughout the period to December 31, 2017and does not expect to breach these covenants for the next 12 months. The credit facility is secured by a number of fixed and floatingcharges over certain assets which include key operating sites of the Company and its subsidiaries. The weighted average rate of interest on borrowings was 2.59% at December 31, 2017 and 1.72% at December 31, 2016. Paymentsof interest on long-term debt were $7.2 million, $2.6 million and $2.3 million in 2017, 2016 and 2015, respectively. The net cash outflows in respect of refinancing costs were $0.0 million, $1.2 million and $1.5 million in 2017, 2016 and 2015,respectively. Note 12. Plant Closure Provisions The principal site giving rise to environmental remediation liabilities is the manufacturing site at Ellesmere Port in the UnitedKingdom, which management believes is the last ongoing manufacturer of TEL. There are also environmental remediation liabilitieson a much smaller scale in respect of our other manufacturing sites in the U.S. and Europe. The liability for estimated closure costsof Innospec’s manufacturing facilities includes costs for decontamination and environmental remediation activities (“remediation”)when demand for TEL diminishes. Movements in the provisions are summarized as follows: (in millions) 2017 2016 2015 Total at January 1 $39.5 $37.7 $34.1 Charge for the period 5.9 4.7 6.8 Measurement period adjustment 2.8 0.0 0.0 Utilized in the period (2.4) (2.7) (2.6) Disposal in the period 0.0 0.0 (0.3) Exchange effect 0.3 (0.2) (0.3) Total at December 31 46.1 39.5 37.7 Due within one year (5.2) (6.7) (6.4) Due after one year $40.9 $32.8 $31.3 Amounts due within one year refer to provisions where expenditure is expected to arise within one year of the balance sheet date.Remediation costs are recognized in cost of goods sold. The provisions for remediation represent the Company’s liability for environmental liabilities and asset retirement obligations. Thecharge for the period in 2017 represents the accretion expense recognized of $3.5 million and a further $2.4 million primarily inrespect of changes in the expected cost and scope of future remediation activities. A discount rate of 8.92% was used in valuing theremediation provision. 86Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Following the Huntsman acquisition, we have recognized $2.8 million of asset retirement obligations as an increase in the value ofthe tangible assets acquired, which will be depreciated over the remaining useful economic life of those assets. We recognize environmental liabilities when they are probable and costs can be reasonably estimated, and asset retirementobligations when there is a legal obligation and costs can be reasonably estimated. The Company has to anticipate the program ofwork required and the associated future expected costs, and comply with environmental legislation in the countries in which itoperates or has operated in. The Company views the costs of vacating our Ellesmere Port site as contingent upon if and when itvacates the site because there is no present intention to do so. Remediation expenditure utilized provisions of $2.4 million, $2.7 million and $2.6 million in 2017, 2016 and 2015, respectively. Note 13. 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 marketparticipants at the measurement date (exit price). The Company utilizes a mid-market pricing convention for valuing the majority ofits assets and liabilities measured and reported at fair value. The Company utilizes market data or assumptions that marketparticipants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to thevaluation technique. These inputs can be readily observable, market corroborated or generally unobservable. The Company primarilyapplies 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 ofunobservable inputs. The Company is able to classify fair value balances based on the observability of those inputs. The Companygives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) andthe lowest priority to unobservable inputs (Level 3 measurement). Financial assets and liabilities are classified in their entirety basedon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of aparticular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities andtheir placement within the fair value hierarchy Levels. In 2017, the Company evaluated the fair value hierarchy levels assigned to itsassets and liabilities, and concluded that there should be no transfers into or out of Levels 1, 2 and 3. 87Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The following table presents the carrying amount and fair values of the Company’s assets and liabilities measured on a recurringbasis: December 31, 2017 December 31, 2016 (in millions) CarryingAmount Fair Value CarryingAmount Fair Value Assets Non-derivatives: Cash and cash equivalents $90.2 $90.2 $101.9 $101.9 Derivatives (Level 1 measurement): Other current and non-current assets: Foreign currency forward exchange contracts 1.1 1.1 0.0 0.0 Interest rate swaps 1.5 1.5 0.4 0.4 Liabilities Non-derivatives: Long-term debt (including current portion) $218.4 $218.4 $268.8 $268.8 Finance leases (including current portion) 5.9 5.9 4.5 4.5 Derivatives (Level 1 measurement): Other non-current liabilities: Foreign currency forward exchange contracts 0.0 0.0 0.6 0.6 Non-financial liabilities (Level 3 measurement): Stock equivalent units 13.6 13.6 9.8 9.8 The following methods and assumptions were used to estimate the fair values of financial instruments: Cash and cash equivalents: The carrying amount approximates fair value because of the short-term maturities of such instruments. Long-term debt and finance leases: Long-term debt principally comprises the term loan and revolving credit facility, which areshown net of deferred finance costs that have been capitalized. The fair value of long-term debt approximates to the carrying value,as the discounting to its present value is offset by the interest rate swaps. Finance leases relate to certain fixed assets in our fuelspecialties and oilfield services businesses. The carrying amount of long-term debt and finance leases approximates to the fair value. Derivatives: The fair value of derivatives relating to foreign currency forward exchange contracts and interest rate swaps are derivedfrom current settlement prices and comparable 88Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) contracts using current assumptions. Foreign currency forward exchange contracts primarily relate to contracts entered into to hedgefuture known transactions or hedge balance sheet net cash positions. The movements in the carrying amounts and fair values of thesecontracts are largely due to changes in exchange rates against the U.S. dollar. Interest rate swaps relate to contracts taken out tohedge interest rate risk on a portion of our credit facilities borrowing. 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 14. Derivative Instruments and Risk Management The Company has limited involvement with derivative instruments and does not trade them. The Company does use derivatives tomanage certain interest rate, foreign currency exchange rate and raw material cost exposures, as the need arises. The Company enters into interest rate swap contracts to reduce interest rate risk on its core debt. As at December 31, 2017, interestrate swaps with a notional value of $149,000,000 were in place. Fixed interest rates payable under the interest rate swaps vary from1.42% to 1.67%. Interest rate swaps in place to hedge interest rate risk on the term loan are for a notional value that matches therepayment profile of the term loan. These interest rate swap contracts have been designated as hedging instruments, and their impacton other comprehensive loss for 2017 was a gain of $1.1 million (2016 – gain $0.4 million). The Company enters into various foreign currency forward exchange contracts to minimize currency exchange rate exposure fromexpected future cash flows. As at December 31, 2017, foreign currency forward exchange contracts with a notional value of $79.2million were in place, with maturity dates of up to one year from the date of inception. These foreign currency forward exchangecontracts have not been designated as hedging instruments, and their impact on the income statement for 2017 was a loss of $0.9million (2016 – gain $4.4 million). As at December 31, 2017 and December 31, 2016 the Company did not hold any raw material derivatives. The Company sells a range of specialty chemicals to major oil refineries and chemical companies throughout the world. Creditlimits, ongoing credit evaluation and account monitoring procedures are intended to minimize bad debt risk. Collateral is notgenerally required. Note 15. Commitments and Contingencies Operating leases The Company has commitments under operating leases primarily for office space, motor vehicles and various items of computer andoffice equipment. The leases are expected to be 89Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) renewed and replaced in the normal course of business. Rental expense was $5.5 million in 2017, $5.2 million in 2016 and $4.5million in 2015. Future commitments under non-cancelable operating leases are as follows: (in millions) 2018 $4.3 2019 3.5 2020 2.8 2021 2.2 2022 1.6 Thereafter 5.9 $20.3 Environmental remediation obligations Commitments in respect of environmental remediation obligations are disclosed in Note 12 of the Notes to the ConsolidatedFinancial Statements. 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 ourbusiness including business and commercial litigation, employee and product liability claims, there are no material pending legalproceedings to which the Company or any of its subsidiaries is a party, or of which any of their property is subject. It is possiblehowever, that an adverse resolution of an unexpectedly large number of such individual items could in the aggregate have a materialadverse 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 affiliatedcompanies primarily in the form of guarantees of debt and performance under contracts entered into as a normal business practice.This includes guarantees of non-U.S. excise taxes and customs duties. As at December 31, 2017, such guarantees which are notrecognized as liabilities in the consolidated financial statements amounted to $3.5 million (December 31, 2016 – $4.7 million). Under the terms of the guarantee arrangements, generally the Company would be required to perform should the affiliated companyfail to fulfill its obligations under the arrangements. In some cases, the guarantee arrangements have recourse provisions that wouldenable the Company to recover any payments made under the terms of the guarantees from securities held of the guaranteed parties’assets. 90Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The Company and its affiliates have numerous long-term sales and purchase commitments in their various business activities, whichare expected to be fulfilled with no adverse consequences material to the Company.

Note 17. Stock-Based Compensation Plans Stock option plans The Company has five active stock option plans, two of which provide for the grant of stock options to employees, one provides forthe grant of stock options to non-employee directors, and another provides for the grant of stock options to key executives on amatching basis provided they use a proportion of their annual bonus to purchase common stock in the Company on the open marketor from the Company. The fifth plan is a savings plan which provides for the grant of stock options to all Company employeesprovided they commit to make regular savings over a pre-defined period which can then be used to purchase common stock uponvesting of the options. The stock options have vesting periods ranging from 24 months to 6 years and in all cases stock optionsgranted expire within 10 years of the date of grant. All grants are at the sole discretion of the Compensation Committee of the Boardof Directors. Grants may be priced at market value or at a premium or discount. The aggregate number of shares of common stockreserved for issuance which can be granted under the plans is 2,640,000. The fair value of stock options is measured on the grant date using either the Black-Scholes model, or in cases where performancecriteria are dependent upon external factors such as the Company’s stock price, using a Monte Carlo model. The following weightedaverage assumptions were used to determine the grant-date fair value of options: 2017 2016 2015 Dividend yield 0.96% 1.38% 1.03% Expected life 5 years 5 years 5 years Volatility 25.3% 25.1% 25.5% Risk free interest rate 1.50% 0.91% 1.05% 91Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The following table summarizes the transactions of the Company’s stock option plans for the year ended December 31, 2017: Number ofOptions WeightedAverage Exercise Price Weighted Average Grant-Date Fair Value Outstanding at December 31, 2016 570,994 $20.38 $21.68 Granted – at discount 79,664 $0.00 $61.39 – at market value 18,843 $70.60 $16.84 Exercised (295,809) $27.04 $14.98 Forfeited (16,026) $13.18 $25.93 Outstanding at December 31, 2017 357,666 $13.74 $35.69 At December 31, 2017, there were 62,102 stock options that were exercisable, 8,577 had performance conditions attached. The Company’s policy is to issue shares from treasury stock to holders of stock options who exercise those options, but if sufficienttreasury stock is not available, the Company will issue previously unissued shares of stock to holders of stock options who exerciseoptions. The stock option compensation cost for 2017, 2016 and 2015 was $4.2 million, $3.3 million and $3.7 million, respectively. The totalintrinsic value of options exercised in 2017, 2016 and 2015 was $2.9 million, $2.8 million and $2.4 million, respectively. The total compensation cost related to non-vested stock options not yet recognized at December 31, 2017 was $5.6 million and thiscost is expected to be recognized over the weighted-average period of 1.90 years. In 2017, the Company recorded a current tax benefit of $3.0 million in respect of stock option compensation. The cash tax benefit realized from stock option exercises totaled $0.3 million, and $0.2 million in 2016 and 2015, respectively. No stock options awards were modified in 2017, 2016 or 2015. Stock equivalent units The Company awards Stock Equivalent Units (“SEUs”) from time to time as a long-term performance incentive. SEUs are cashsettled equity instruments conditional on certain performance criteria and linked to the Innospec Inc. share price. SEUs have vestingperiods ranging from 11 months to 4 years and in all cases SEUs granted expire within 10 years of the date of grant. Grants may bepriced 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 31,2017 the liability for SEUs of $13.6 million is located in accrued liabilities in the consolidated balance sheets until they are cashsettled. 92Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The fair value of SEUs is measured at the balance sheet date using either the Black-Scholes model, or in cases where performancecriteria are dependent upon external factors such as the Company’s stock price, using a Monte Carlo model.

The charges for SEUs are spread over the life of the award subject to a revaluation to fair value each quarter. The revaluation mayresult in a charge or a credit to the income statement in the quarter dependent upon our share price and other performance criteria. The SEU compensation cost for 2017, 2016 and 2015 was $6.6 million, $4.7 million and $4.9 million, respectively. The totalintrinsic value of SEUs exercised in 2017, 2016 and 2015 was $1.7 million, $1.8 million and $2.4 million, respectively. The weighted-average remaining vesting period of non-vested SEUs is 1.73 years. 93Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Note 18.

Recently Issued Accounting Pronouncements In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of NetPeriodic Pension Cost and Net Periodic Postretirement Benefit Cost. ASU 2017-07 requires companies to present the service costcomponent of net benefit cost in the same line items in which they report compensation cost. Companies will present all othercomponents of net benefit cost outside operating income, if 94(1) (1) (1) Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) this subtotal is presented. The new standard is effective for annual periods beginning after December 15, 2017, including interimperiods within those fiscal years. The Company has determined the Standard will impact the operating subtotal as reported in theCompany’s consolidated statements of income with a reduction to operating income of $4.7 million and a corresponding increase inother non-operating income for the year ended December 31, 2017. In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Revision to Lease Accounting, which amendsASC Topic 842, Leases. The ASU requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases(other than leases that meet the definition of a short-term lease). The new standard is effective for fiscal years beginning afterDecember 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The new standard must beadopted using a modified retrospective transition method, and provides for certain practical expedients. Transition will requireapplication of the new guidance at the beginning of the earliest comparative period presented. The Standard will have a materialimpact on our consolidated balance sheet. The most significant impact will be the recognition of Right-of-use assets and leaseliabilities for operating leases. The Company is still assessing the effect of the standard on its ongoing financial reporting. In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606) .ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled whenproducts are transferred to customers. The new standard will become effective for annual reporting periods beginning afterDecember 15, 2017. ASU 2014-09 may be applied retrospectively to each prior period presented in the financial statements (fullretrospective approach) or retrospectively with the cumulative effect of initially applying the standard recognized as an adjustment tothe opening balance of retained earnings as of the date of adoption (modified retrospective approach). We will adopt the new revenuestandard on January 1, 2018 utilizing the modified retrospective approach. We have spent significant time evaluating, analyzing anddocumenting the expected impact of ASU 2014-09 on our financial statements. We have performed a detailed review of keycontracts representative of our different businesses and product lines, reviewing various industry publications, and comparing ourcurrent accounting policies to the principles and requirements outlined in the new Standard. Our assessment at this stage is that wedo not expect the new revenue recognition standard will have a material impact on our financial statements upon adoption. Note 20. Related Party Transactions Mr. Robert I. Paller has been a non-executive director of the Company since November 1, 2009. The Company has retained andcontinues to retain Smith, Gambrell & Russell, LLP (“SGR”), a law firm with which Mr. Paller holds a position. In 2017, 2016 and2015 the Company incurred fees payable to SGR of $0.4 million, $0.5 million and $0.3 million, respectively. As at December 31,2017 and at December 31, 2016, the Company did not have any amounts outstanding due to SGR. 95Table of ContentsNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Note 21. Subsequent Events The Company has evaluated subsequent events through the date that the consolidated financial statements were issued, and hasconcluded that no additional disclosures are required in relation to events subsequent to the balance sheet date. 96Table of ContentsItem 9Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None. Item 9AControls 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 participationof our management, our Chief Executive Officer and our Chief Financial Officer concluded that the Company’s “disclosure controlsand procedures” (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) were effective as ofDecember 31, 2017. 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 andmaintaining adequate internal control over financial reporting (within the meaning of Rule 13a-15(f) under the Securities ExchangeAct of 1934). The Company’s internal control over financial reporting is a process designed to provide reasonable assuranceregarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withaccounting 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 dispositionsof our assets; • provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements inaccordance with accounting principles generally accepted in the United States of America and that our receipts andexpenditures 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 ofassets 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 allerrors or fraud. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls maybecome inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures maydeteriorate. Based on criteria in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of theTreadway Commission the evaluation of our management, 97Table of Contentsincluding the Chief Executive Officer and the Chief Financial Officer, concluded that the Company did maintain effective internalcontrol over financial reporting as of December 31, 2017. Our independent registered public accounting firm KPMG Audit Plc, has audited our consolidated financial statements and theeffectiveness of our internal control over financial reporting as of December 31, 2017. Their report is included in Item 8 of thisAnnual 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. Thisis intended to result in refinements to processes throughout the Company. On December 30, 2016 we acquired the European Differentiated Surfactants business from Huntsman (“Huntsman”). We excludedthe operations of Huntsman from the scope of our Sarbanes-Oxley Section 404 management report on internal controls over financialreporting as of December 31, 2016. As at December 31, 2017, we have completed the implementation of an internal control structurefor the acquired operations including a new information system platform.
