Management's Responsibility for the Combined Financial Statements Management is responsible for the preparation and fair presentation of these combined financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of combined financial statements that are free from material misstatement, whether due to fraud or error. Auditors' Responsibility Our responsibility is to express an opinion on these combined financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the combined financial statements are free from material misstatement. An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the combined financial statements. The procedures selected depend on the auditor's judgment, including the assessment of the risks of material misstatement of the combined financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the Business' preparation and fair presentation of the combined financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Business' internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the combined financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion. Opinion In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Business as of September 30, 2018 and 2017, and the results of its operations and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America. Emphasis of Matter The Business is wholly-owned by Cabot Corporation ("Parent"). As described in Note 2, the combined financial statements include certain allocations from Parent. Accordingly, the combined fmancial information herein may not necessarily reflect the combined fmancial position, results of operations, and cash flows of the Business had the Business been an independent Business during the periods presented. This report is intended solely for the information and use of the Boards of Directors and managements of Cabot Corporation and parties who have signed the "Prospective Buyer Supplement" and is not intended to be and should not be used by anyone other than these specified parties.

DESCRIPTION OF BUSINESS The Specialty Fluids Business ("the Business" or "Specialty Fluids") of Cabot Corporation ("Cabot" or "Parent") produces and markets a range of cesium products that include cesium formate brines and other fine cesium chemicals. Cesium formate brines are used as a drilling and completion fluid primarily in high pressure and high temperature oil and gas well construction. Cesium formate products are solids-free, high-density fluids that have a low viscosity, enabling safe and efficient well construction and workover operations. The fluid is resistant to high temperatures, minimizes damage to producing reservoirs and is readily biodegradable in accordance with the testing guidelines set by the Organization for Economic Cooperation and Development. In a majority of applications, cesium formate is blended with other formates or products. Fine cesium chemicals are used across a wide range of industries and applications that include catalysts, doping agents and brazing fluxes. Fine cesium chemicals enable process performance benefits and yield improvements and help prevent or mitigate pollution in the applications they serve. Sales of the Business's cesium formate products are made to oil and gas operating companies directly by the Business's employees and sales representatives and indirectly through oil field service companies. The Business generally rents cesium formate to customers for use in drilling operations on a short-term basis and on occasion makes direct sales to customers outside of the rental process. After completion of a job under the rental process, the customer returns the remaining fluid to the Business and it is reprocessed for use in subsequent well operations. Any fluid that is not returned to the Business is paid for by the customer. Sales of the Business's fine cesium chemicals are made by the Business's employees and through distributors and sales representatives. In prior years, a large portion of the Business's fluids has been used for drilling and completion of wells in the North Sea with a limited number of customers, where the Business has supplied cesium formate- based fluids for both reservoir drilling and completion activities on large gas and condensate field projects in the Norwegian Continental Shelf. In fiscal 2018, the Business expanded the use of its fluids to drilling operations outside of the North Sea, particularly in Asia/the Middle East. The Business's mine and cesium formate and fine cesium chemical manufacturing facility are located in Manitoba, Canada, and the Business has fluid blending and reclamation facilities in Aberdeen, Scotland and in Bergen, Norway. In addition, the Business warehouses fluid and fine cesium chemical products at various locations around the world to support existing and potential operations. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation - The combined financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). These combined financial statements are prepared on a stand-alone basis and are derived from the consolidated financial statements and accounting records of Cabot. The preparation of these combined financial statements in confo1mity with GAAP requires management to make use of estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results may differ from those estimates. All interbusiness balances and transactions between the entities within the Business have been eliminated. -8- Allocation of Shared Expenses - To the extent that an asset, liability, revenue or expense is directly associated with the Business, it is reflected in the accompanying combined financial statements. Cash and cash equivalents held by Cabot at the corporate level are not specifically allocated to the Business. Accordingly, cash and cash equivalents have not been allocated to the Business for any of the periods presented. Cabot's debt and the related interest expense have not been allocated to the Business for any of the periods presented since the Business is not the primary obligor of the debt, and Cabot's borrowings were not directly attributable to the Business. The combined financial statements also include allocations of indirect expenses. Indirect expenses represent costs related to centralized corporate functions such as executive oversight, business development, information technology, accounting, legal and human resources that Cabot has incurred. Such indirect expenses have been allocated on a systemic basis, principally driven by headcount. The Combined Statements of Operations reflect the allocation of indirect expenses totaling $5,548 thousand, $5,031 thousand, and $4,867 thousand for the years ended September 30, 2018, 2017, and 2016, respectively. Actual costs which may have been incurred if the Business had been a stand-alone Business during the periods presented would depend on a number of factors, including how the Business chose to organize itself, which functions, if any, were outsourced or performed by Cabot employees and strategic decisions made in areas such as information technology systems and infrastructure. As such, the combined financial information herein may not necessarily reflect the combined financial position, results of operations and cash flows of the Business in the future or what it would have been had the Business been an independent business during the periods presented. Notes Receivable - Related Parties and Notes Payable - Related Parties - Certain Specialty Fluids entities are lenders and/or borrowers in Cabot's intercompany notes receivable and notes payable program. The loans have market interest rates, terms that are customary for these types of loans and are payable on demand. Cabot and the Business have asserted that there is no intention to demand payment; accordingly, such amounts have been classified as long-term. Inventories - Inventories represent fine cesium chemical products. Inventories are valued using the average cost method and are stated at lower of cost or market. The average cost of fine cesium chemicals inventory is recognized as cost of sales when products are sold. Assets Held For Rent - Assets held for rent represent cesium formate product that is available to customers in the normal course of business. At September 30, 2018 and 2017 assets held for rent also included $5,374 thousand and $5,300 thousand, respectively, of cesium ore, a majority of which will be converted into cesium formate. Assets held for rent are stated at average cost and the average cost of barrels lost in the normal course of business are recognized in cost of sales. $3,875 thousand of costs associated with mine development were capitalized into assets held for rent in fiscal 2018. No mine development costs were capitalized into assets held for rent in fiscal 2017. Property, Plant and Equipment- Property, plant and equipment are recorded at cost. Depreciation of property, plant and equipment is calculated using the straight-line method over the estimated useful lives of the assets. The depreciable lives for buildings, machinery and equipment, and other fixed assets are between twenty and twenty-five years, ten and twenty-five years, and three and twenty-five years, respectively. The cost of mine development projects is included in machinery and equipment. Mine development projects are depreciated, and the depreciation is capitalized into assets held for rent over the estimated mining period of the cesium ore to which the project enabled access. -9- The cost and accumulated depreciation for property, plant and equipment sold, retired, or otherwise disposed of are removed from the Combined Balance Sheets and resulting gains or losses are included in Income from operations before income taxes in the Combined Statements of Operations. Expenditures for repairs and maintenance are charged to expense as incurred. Expenditures for major renewals and betterments, which significantly extend the useful lives of existing plant and equipment, are capitalized and depreciated. Asset Retirement Obligations - The Business estimates incremental costs for special handling, removal and disposal costs of materials that may or will give rise to asset retirement obligations ("AROs") and then discounts the expected costs back to the current year using a credit adjusted risk free rate. The estimation of AROs is subject to a number of inherent uncertainties including: (a) the timing of when any ARO may be incurred, (b) the ability to accurately identify and reasonably estimate the costs of all materials that may require special handling or treatment, ( c) the ability to assess the relative probability of different scenarios which could give rise to an ARO, and ( d) the other factors outside the Business' control, including changes in regulations, costs and interest rates. The Business recognizes ARO liabilities and costs when the timing and/or settlement can be reasonably estimated. The ARO liabilities were $4,097 thousand and $4,014 thousand at September 30, 2018 and 2017, respectively, and are included in Accrued liabilities and Other liabilities in the Combined Balance Sheets. Accumulated Other Comprehensive Income (Loss)-Accumulated other comprehensive income (loss) ("AOCI"), which is included as a component of Parent company equity in the Combined Balance Sheets, . primarily includes currency translation adjustments and minimum pension liability adjustments. Foreign Currency Translation and Transactions -The U.S. dollar is the reporting currency and also the functional currency of the majority of the operations. Assets and liabilities of non-U.S. dollar subsidiaries in Canada and Singapore are translated into U.S. dollars at exchange rates in effect at the balance sheet dates. Income and expense items are translated at average monthly exchange rates during the year. Unrealized currency translation adjustments are included as a separate component of AOCI within Parent company equity. Realized and unrealized foreign currency gains and losses arising from transactions denominated in currencies other than the subsidiary's functional currency are reflected in earnings. In fiscal 2018, 2017 and 2016, net foreign currency transaction loss of $27 thousand, loss of $277 thousand, and gain of $421 thousand, respectively, are included in Other expense in the Combined Statements of Operations. Revenue Recognition - Revenue in Specialty Fluids arises primarily from the rental of cesium formate. This revenue is recognized throughout the rental period based on the contracted rental terms net of customer allowances and incentives. Customers are also billed, and revenue is recognized, typically at the end of the project, for cesium formate product that is not returned. The Business also generates revenues from cesium formate sold outside of a rental process and the sale of fine cesium chemicals. Product sale revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability is reasonably assured. Shipping and handling charges related to sales transactions are recorded as sales revenue when billed to customers or included in the sales price. Taxes collected on sales to customers are excluded from revenues. - 10 - Cost of Sales - Costs of sales consists of the cost of raw and packaging materials, direct manufacturing costs, depreciation, internal transfer costs, inspection costs, inbound and outbound freight and shipping and handling costs, plant purchasing and receiving costs, fluid reclamation costs and other overhead expenses necessary to produce products. Accounts Receivable - Trade receivables are recorded at the invoiced amount and generally do not bear interest. The Business also maintains an allowance for doubtful accounts based on an assessment of the collectability of specific customer accounts, the aging of accounts receivable and other economic information on both a historical and prospective basis. Customer account balances are charged against the allowance when it is probable the receivable will not be recovered. Stock-Based Compensation - Stock-based awards (related to shares of Cabot stock) granted to employees of the Business are recorded as compensation expense using the fair value method. Under the fair value recognition provisions, stock-based compensation cost is measured at the grant date based on the fair value of the award, and is recognized as expense over the service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited, and an estimate of what level of performance Cabot will achieve for performance-based stock awards. The fair value ofrestricted stock units is detennined using the closing price of Cabot stock on the day of the grant. Stock-based compensation expense, net of tax benefit, included in the Business' Combined Statements of Operations were $328 thousand, $221 thousand and $161 thousand in the years ended September 30, 2018, 2017 and 2016, respectively. Income Taxes - Income taxes are computed on a separate return basis. Accordingly, income tax charges or benefits have been computed as if each of the component entities of the Business filed separate income tax returns. Deferred income taxes are determined based on the estimated future tax effects of differences between financial statement carrying amounts and the tax bases of existing assets and liabilities. Deferred tax assets are recognized to the extent that realization of those assets is considered to be more likely than not. A valuation allowance is established for deferred taxes when it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Business records benefits for uncertain tax positions based on an assessment of whether the position is more likely than not to be sustained by the taxing authorities. If this threshold is not met, no tax benefit of the uncertain tax position is recognized. If the threshold is met, the tax benefit that is recognized is the largest amount that is greater than 50% likely of being realized upon ultimate settlement. This analysis presumes the taxing authorities' full knowledge of the positions taken and all relevant facts but does not consider the time value of money. The Business also accrues for interest and penalties, as applicable; on its uncertain tax positions and includes such charges in its income tax provision in the Combined Statements of Operations. Selling and Administrative Expenses - Selling and administrative expenses consist of personnel costs of sales and administrative personnel, general office expenses and other expenses not directly related to manufacturing operations. Research and Technical Expenses - Research and technical expenses include personnel costs, equipment and material expenditures, and consultant fees of the research and technical function. Use of Estimates - The preparation of combined financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the combined financial - 11 - statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. 3.

EMPLOYEE BENEFIT PLANS Cabot provides defined benefit plans for its employees, including certain employees in the Business. The eligible employees of the Business are participants in either the U.S. plan that covers substantially all of Cabot's U.S. employees or a foreign plan that covers all of the Business' employees in Canada. The U.S. defined benefit pension plan is frozen. Cabot also provides a postretirement benefit plan for certain U.S. employees, including those employed by the Business, which includes medical coverage and life insurance. The Business's participation in the U.S. defined benefit pension plan and postretirement benefit plan is deemed not material to the Combined Financial Statements of the Business and accordingly, the following information is presented based on the Business' participation in the Canadian plan only.

The investments are classified as Level 2 investments. For Level 2 investments, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; or where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability.

In connection with various other agreements, including service and supply agreements with customers, the Business has provided indemnities for certain contingencies and routine warranties. The Business is unable to estimate the maximum potential liability for these types of indemnities as a maximum obligation is not explicitly stated in most cases and the amounts, if any, are dependent upon the outcome of future contingent events, the nature and likelihood of which cannot be reasonably estimated. The duration of the indemnities varies, and in many cases are indefinite. The Business has not recorded any liability for these indemnities in the combined financial statements, except as otherwise disclosed. 12. CONCENTRATION OF CREDIT RISK Credit risk represents the loss that would be recognized if counterparties failed to completely perform as contracted. Financial instruments that subject the Business to credit risk consist principally of trade receivables. Furthermore, concentrations of credit risk exist for groups of customers when they have similar economic characteristics that would cause their ability to meet contractual obligations to be similarly affected by changes in economic or other conditions. Credit risk for the Business for the years ended September 30, 2018, 2017 and 2016 was concentrated in the following customers who each comprised more than 10% of Net sales and other operating revenue in one or more years: September 30 2018 2017 2016 Customer 1 12% 10% 4% Customer 2 0% 0% 22% Customer 3 10% 11% 5% Customer 4 6% 25% 26% Customer 5 47% 27% 20% Customer 6 0% 0% 10% Total 75% 73% 87% No additional customers accounted for more than 10% of Net sales and other operating revenue during the years ended September 30, 2018, 2017 and 2016.
