NOTES TO THE UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 – BASIS OF PRESENTATION

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X under the Securities Exchange Act of 1934. Accordingly, they do not include all the information and notes necessary for a comprehensive presentation of financial position, results of operations and cash flows.

It is our opinion, however, that all adjustments (consisting of normal, recurring adjustments, unless otherwise disclosed) have been made which are necessary for the financial statements to be fairly stated. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K filed on February 17, 2016.

The results for the interim period covered by this report are not necessarily indicative of the results to be expected for the full year.

During the quarter, we announced a change in the organization structure of the Group. As a result of these changes, information that the Company’s chief operating decision maker regularly reviews for purposes of allocating resources and assessing performance has changed. Therefore, beginning in this quarter of 2016, the Company has reported its financial performance based on our new segments: Fuel Specialties, Performance Chemicals, Oilfield Services and Octane Additives (See Note 2 of the Notes to the Consolidated Financial Statements for further information).

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

NOTE 2 – SEGMENT REPORTING

In April 2016, we finalized changes to our reporting segments to reflect the development of our management structure and strategy. As a result of these changes, information that the Company’s chief operating decision maker regularly reviews for purposes of allocating resources and assessing financial performance has changed. Therefore beginning in this quarter of 2016, the Company has reported its financial performance based on the four reportable segments described below.

We have recast certain prior period amounts to conform to the way we internally manage and monitor segment performance.

The Fuel Specialties, Performance Chemicals and Oilfield Services segments operate in markets where we actively seek growth opportunities although their ultimate customers are different. The Octane Additives segment is expected to decline in the near future as our one remaining refinery customer transitions to unleaded fuel.

The Company evaluates the performance of its segments based on operating income. The following table analyzes sales and other financial information by the Company’s reportable segments:

The pension credit relates to the United Kingdom defined benefit pension plan which is closed to future service accrual. The charges related to our other much smaller pension arrangements in the U.S. and overseas are included in the segment and income statement captions consistent with the related employees’ costs.

The following table presents a summary of the depreciation and amortization charges incurred by the Company’s reportable segments:

Table of Contents

In the three and six months ended June 30, 2016, the average number of anti-dilutive options excluded from the calculation of diluted earnings per share were 471 and 471, respectively (three and six months ended June 30, 2015 – 21,959 and 33,734, respectively).

Amortization expense

13

Table of Contents

The amortization of prior service credit and actuarial net losses is a reclassification out of accumulated other comprehensive loss into selling, general and administrative expenses.

The Company also maintains an unfunded defined benefit pension plan covering a number of its current and former employees in Germany (the “German plan”). The German plan is closed to new entrants and has no assets. The net pension charge for the German plan for the three and six months ended June 30, 2016, was $0.2 million and $0.4 million, respectively (three and six months ended June 30, 2015 - $0.2 million and $0.4 million, respectively).

All of the unrecognized tax benefits, interest and penalties, would impact our effective tax rate if recognized.

We recognize accrued interest and penalties associated with uncertain tax positions as part of income taxes in our consolidated statements of income.

Table of Contents

The Company or one of its subsidiaries files income tax returns with the U.S. federal government, and various state and foreign jurisdictions. One of the Company’s U.S. subsidiaries is currently subject to a state tax examination in respect of 2012 through to 2014 inclusive. The Company currently anticipates that adjustments, if any, arising out of this tax audit would not result in a material change to the Company’s financial position as at June 30, 2016.

As previously disclosed, the Company’s German subsidiaries are subject to a tax audit in respect of 2010 through to 2014 inclusive. The Company currently anticipates that adjustments, if any, arising out of this tax audit would not result in a material change to the Company’s financial position as at June 30, 2016.

The Company and its U.S. subsidiaries remain open to examination by the IRS for years 2012 onwards. The Company’s subsidiaries in foreign tax jurisdictions are open to examination including France (2013 onwards), Germany (2010 onwards), Switzerland (2014 onwards) and the United Kingdom (2014 onwards).

The Company is in a position to control whether or not to repatriate foreign earnings and we currently do not expect to make a repatriation in the foreseeable future. No taxes have been provided for on the unremitted earnings of our overseas subsidiaries as any tax basis differences relating to investments in these overseas subsidiaries are considered to be permanent in duration. The amount of unremitted earnings at December 31, 2015 was approximately $775 million. If these earnings are remitted, additional taxes could result after offsetting foreign income taxes paid although the calculation of the additional taxes is not practicable to compute at this time.

NOTE 9 – PLANT CLOSURE PROVISIONS

The liability for estimated closure costs of Innospec’s manufacturing facilities includes costs for decontamination and environmental remediation activities (“remediation”). The principal site giving rise to remediation liabilities is the manufacturing site at Ellesmere Port in the United Kingdom. There are also remediation liabilities on a much smaller scale in respect of our other manufacturing sites in the U.S. and Europe.

Movements in the provisions are summarized as follows:

15

Table of Contents

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

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

Cash and cash equivalents and short-term investments: 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 revolving credit facility. Finance leases relate to certain fixed assets in our Oilfield Services business. The carrying amount of long-term debt and finance leases approximates the fair value.

Derivatives: The fair value of derivatives relating to foreign currency forward exchange contracts are derived from current settlement prices and comparable contracts using current assumptions. Foreign currency forward exchange contracts primarily relate to contracts entered into to hedge future known transactions or hedge balance sheet net cash positions. The movements in the carrying amounts and fair values of these contracts are largely due to changes in exchange rates against the U.S. dollar.

16

Table of Contents

Acquisition-related contingent consideration: Contingent consideration payable in cash is discounted to its estimated fair value at each balance sheet date. Where contingent consideration is dependent upon pre-determined financial targets, an estimate of the fair value of the likely consideration payable is made at each balance sheet date. The carrying value of the contingent consideration at the balance sheet dates is based on the estimated EBITDA (earnings before interest, taxes, depreciation and amortization) and free cash flow generated by Independence Oilfield Chemicals LLC (“Independence”) through the period to October 31, 2016. The contingent consideration payable in relation to the acquisition of Independence is based on management’s latest forecasts of the business and on the current trading performance. The results of the Independence business are particularly sensitive to the level of exploration, development and production activity of our customers in the oil and gas sector, which is directly affected by trends in oil prices.

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 depending on the terms of each grant.

NOTE 11 – DERIVATIVE INSTRUMENTS AND RISK MANAGEMENT

The Company enters into various foreign currency forward exchange contracts to minimize currency exchange rate exposure from expected future cash flows. As at June 30, 2016 the contracts have maturity dates of up to fifteen months at the date of inception. These foreign currency forward exchange contracts have not been designated as hedging instruments, and their impact on the income statement for the first six months of 2016 was a gain of $3.0 million.

NOTE 12 – COMMITMENTS AND CONTINGENCIES

Legal matters

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

Guarantees

The Company and certain of the Company’s consolidated subsidiaries are contingently liable for certain obligations of affiliated companies primarily in the form of guarantees of debt and performance under contracts entered into as a normal business practice. This includes guarantees of non-U.S. excise taxes and customs duties. As at June 30, 2016, such guarantees which are not recognized as liabilities in the consolidated financial statements amounted to $3.7 million.

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

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

NOTE 13 – STOCK-BASED COMPENSATION PLANS

The Company grants stock options and stock equivalent units (“SEUs”) from time to time as a long-term performance incentive. In certain cases the grants are subject to performance conditions such as the Company’s stock price. Where performance conditions apply the Monte Carlo simulation model is used to determine the fair values. Otherwise the Black-Scholes model is used to determine the fair values.

Stock option plans

The following table summarizes the transactions of the Company’s stock option plans for the six months ended June 30, 2016:

At June 30, 2016, there were 111,004 stock options that were exercisable, of which 25,912 had performance conditions attached.

The stock option compensation cost for the first six months of 2016 was $1.9 million (2015 – $1.8 million). The total intrinsic value of options exercised in the first six months of 2016 was $1.6 million (2015 – $2.0 million).

The total compensation cost related to non-vested stock options not yet recognized at June 30, 2016 was $4.7 million and this cost is expected to be recognized over the weighted-average period of 2.14 years.

Stock equivalent units

The following table summarizes the transactions of the Company’s SEUs for the six months ended June 30, 2016:

18

Table of Contents

At June 30, 2016 there were 67,265 SEUs that are exercisable, of which 58,663 had performance conditions attached.

The charges for SEUs are spread over the life of the award subject to a revaluation to fair value each quarter. The revaluation may result 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 the first six months of 2016 was $0.0 million (2015 - $1.4 million). The total intrinsic value of SEUs exercised in the first six months of 2016 was $1.2 million (2015 - $2.1 million).

The weighted-average remaining vesting period of non-vested SEUs is 1.84 years.

Additional exceptional long-term incentive plan

A maximum of $3.0 million of our cash-settled long-term incentives is accounted for as share-based compensation and the fair value is calculated on a quarterly basis using a Monte Carlo model. The fair values at each of the balance sheet dates are summarized as follows:

The following assumptions were used in the Monte Carlo model at June 30:

NOTE 15 – RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers ASC Topic 606, which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. The original effective date for ASU 2014-09 was for annual and interim periods within those years beginning after December 15, 2016. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers – Deferral of the Effective Date, which defers the effective date of ASU 2014-09 for one year and permits early adoption as early as the original effective date of ASU 2014-09. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company has been evaluating the potential timing and impact of adopting the new revenue standard on its consolidated financial statements and has not yet determined the effect of the standard on its ongoing financial reporting.

In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Revision to Lease Accounting, which amends ASC 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 after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. The Company has not yet determined the effect of the standard on its ongoing financial reporting.

In March 2016, the FASB issued Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-based Payment Accounting, which amends ASC Topic 718, Compensation – Stock Compensation. The ASU includes provisions intended to simplify various aspects related to how Share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. Early adoption is permitted. The Company has not yet determined the effect of the standard on its ongoing financial reporting.
