1 Basis of Presentation and Summary of Significant Accounting Policies

Waters Corporation (“Waters®” or the “Company”) is an analytical instrument manufacturer that primarily designs, manufactures, sells and services, through its Waters Division, high performance liquid chromatography (“HPLC”), ultra performance liquid chromatography (“UPLC®” and together with HPLC, referred to as “LC”) and mass spectrometry (“MS”) technology systems and support products, including chromatography columns, other consumable products and comprehensive post-warranty service plans. These systems are complementary products that are frequently employed together (“LC-MS”) and sold as integrated instrument systems using a common software platform. LC is a standard technique and is utilized in a broad range of industries to detect, identify, monitor and measure the chemical, physical and biological composition of materials, and to purify a full range of compounds. MS instruments are used in drug discovery and development, including clinical trial testing, the analysis of proteins in disease processes (known as “proteomics”), nutritional safety analysis and environmental testing. LC-MS instruments combine a liquid phase sample introduction and separation system with mass spectrometric compound identification and quantification. Through its TA Division (“TA®”), the Company primarily designs, manufactures, sells and services thermal analysis, rheometry and calorimetry instruments, which are used in predicting the suitability and stability of fine chemicals, pharmaceuticals, water, polymers and viscous liquids for various industrial, consumer goods and healthcare products, as well as for life science research. The Company is also a developer and supplier of software-based products that interface with the Company’s instruments, as well as other suppliers’ instruments, and are typically purchased by customers as part of the instrument system.

The Company’s interim fiscal quarter typically ends on the thirteenth Saturday of each quarter. Since the Company’s fiscal year end is December 31, the first and fourth fiscal quarters may have more or less than thirteen complete weeks. The Company’s second fiscal quarters for 2015 and 2014 ended on July 4, 2015 and June 28, 2014, respectively.

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the instructions to the Quarterly Report on Form 10-Q and do not include all of the information and note disclosures required by generally accepted accounting principles (“GAAP”) in the United States of America. The consolidated financial statements include the accounts of the Company and its subsidiaries, most of which are wholly owned. All material inter-company balances and transactions have been eliminated.

The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities at the dates of the financial statements. Actual amounts may differ from these estimates under different assumptions or conditions.

It is management’s opinion that the accompanying interim consolidated financial statements reflect all adjustments (which are normal and recurring) that are necessary for a fair statement of the results for the interim periods. The interim consolidated financial statements should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, as filed with the U.S. Securities and Exchange Commission on February 27, 2015.

Cash, Cash Equivalents and Investments

Cash equivalents represent highly liquid investments, with original maturities of 90 days or less, while investments with longer maturities are classified as investments. The Company maintains cash balances in various operating accounts in excess of federally insured limits, and in foreign subsidiary accounts in currencies other than U.S. dollars. As of July 4, 2015 and December 31, 2014, $2,162 million out of $2,209 million and $1,971 million out of $2,055 million, respectively, of the Company’s total cash, cash equivalents and investments were held by foreign subsidiaries and may be subject to material tax effects on distribution to U.S. legal entities.

Property, Plant and Equipment

During the three and six months ended June 28, 2014, the Company recorded a $4 million impairment charge related to a write-down in the fair value of a building in the U.K. The fair value of the building was determined based on a real estate market analysis and is classified as held-for-sale. The carrying value of the building was $4 million at both July 4, 2015 and December 31, 2014 and is included in other current assets in the consolidated balance sheets.

Fair Value Measurements

In accordance with the accounting standards for fair value measurements and disclosures, certain of the Company’s assets and liabilities are measured at fair value on a recurring basis as of July 4, 2015 and December 31, 2014. Fair values determined by Level 1 inputs utilize observable data, such as quoted prices in active markets. Fair values determined by Level 2 inputs utilize data points other than quoted prices in active markets that are observable either directly or indirectly. Fair values determined by Level 3 inputs utilize unobservable data points for which there is little or no market data, which require the reporting entity to develop its own assumptions.

The following table represents the Company’s assets and liabilities measured at fair value on a recurring basis at July 4, 2015 (in thousands):

|  |  |  |  | Quoted Prices |  |  |  |  |  |  |

The fair values of the Company’s cash equivalents, investments, 401(k) restoration plan assets and foreign currency exchange contracts are determined through market and observable sources and have been classified as Level 2. These assets and liabilities have been initially valued at the transaction price and subsequently valued, typically utilizing third-party pricing services. The pricing services use many inputs to determine value, including reportable trades, benchmark yields, credit spreads, broker/dealer quotes, current spot rates and other industry and economic events. The Company validates the prices provided by third-party pricing services by reviewing their pricing methods and obtaining market values from other pricing sources. After completing these validation procedures, the Company did not adjust or override any fair value measurements provided by third-party pricing services as of July 4, 2015 and December 31, 2014.

Fair Value of Contingent Consideration

The fair value of the Company’s liability for contingent consideration related to the July 2014 acquisition of Medimass Research, Development and Service Kft. is determined using a probability-weighted discounted cash flow model, which uses significant unobservable inputs, and has been classified as Level 3. Subsequent changes in the fair value of the contingent consideration liability are recorded in the results of operations. The fair value of the contingent consideration liability associated with future earnout payments is based on several factors, including the development of future products, estimated sales of those products and a discount rate reflective of the Company’s creditworthiness. A change in any of these unobservable inputs can significantly change the fair value of the contingent consideration. Although there is no contractual limit, the fair value of future contingent consideration payments was estimated to be $4 million at both July 4, 2015 and December 31, 2014, based on the Company’s best estimate, as the earnout is based on future sales of certain products through 2034. There have been no changes in significant assumptions since December 31, 2014 and the change in fair value since then is primarily due to change in time value of money.

Fair Value of Other Financial Instruments

The Company’s cash, accounts receivable, accounts payable and variable interest rate debt are recorded at cost, which approximates fair value. The carrying value of the Company’s fixed interest rate debt was $450 million and $550 million at July 4, 2015 and December 31, 2014, respectively. The fair value of the Company’s fixed interest rate debt was estimated using discounted cash flow models, based on estimated current rates offered for similar debt under current market conditions for the Company. The fair value of the Company’s fixed interest rate debt was estimated to be $454 million and $558 million at July 4, 2015 and December 31, 2014, respectively, using Level 2 inputs.

Derivative Transactions

The Company enters into foreign currency exchange contracts to manage exposures to changes in foreign currency exchange rates on certain inter-company balances and short-term assets and liabilities. Principal hedged currencies include the Euro, Japanese yen, British pound and Brazilian real. At July 4, 2015 and December 31, 2014, the Company held forward foreign exchange contracts with notional amounts totaling $112 million and $110 million, respectively.

Stockholders’ Equity

In May 2014, the Company’s Board of Directors authorized the Company to repurchase up to $750 million of its outstanding common stock over a three-year period and authorized the extension of the May 2012 program until May 2015. During the six months ended July 4, 2015 and June 28, 2014, the Company repurchased 1.3 million and 1.7 million shares of the Company’s outstanding common stock at a cost of $165 million and $178 million, respectively, under the May 2012 and May 2014 authorizations. As of July 4, 2015, the Company repurchased an aggregate of 7.6 million shares at a cost of $750 million under the May 2012 repurchase program, which is now completed. The Company has a total of $604 million authorized for future repurchases under the May 2014 plan. In addition, the Company repurchased $6 million and $7 million of common stock related to the vesting of restricted stock units during the six months ended July 4, 2015 and June 28, 2014, respectively. The Company believes that it has the financial flexibility to fund these share repurchases given current cash levels and debt borrowing capacity, as well as to invest in research, technology and business acquisitions to further grow the Company’s sales and profits.

Product Warranty Costs

The Company accrues estimated product warranty costs at the time of sale, which are included in cost of sales in the consolidated statements of operations. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers, the Company’s warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. The amount of the accrued warranty liability is based on historical information, such as past experience, product failure rates, number of units repaired and estimated costs of material and labor. The liability is reviewed for reasonableness at least quarterly.

4 Acquisitions

The Company accounts for business acquisitions under the accounting standards for business combinations. The results of each acquisition have been included in the Company’s consolidated results as of the acquisition date and the purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. Any excess of the fair value consideration transferred over the estimated fair values of the net assets acquired is recognized as goodwill.

On May 22, 2015, the Company acquired the net assets of the Electroforce business of the Bose Corporation (“Electroforce”), a manufacturer of testing systems, for approximately $9 million in cash. Electroforce’s core business is the manufacturing of dynamic mechanical testing systems used to characterize medical devices, biologic and engineered materials. The Electroforce test instruments are based on unique motor designs that are quiet, energy-efficient, scalable and deliver high performance over a wide range of force and frequency. Electroforce was acquired to expand the TA Division’s product offering into new markets, while leveraging the technology, infrastructure and customer bases of the combined organizations. The Company has allocated $4 million of the purchase price to intangible assets comprised of technology, customer relationships and trade name. The Company is amortizing the technology and customer relationships over ten years and five years, respectively. The remaining purchase price of $1 million was accounted for as goodwill, which is deductible for tax purposes.

The principal factor that resulted in recognition of goodwill in the acquisition of Electroforce is that the purchase price was based, in part, on cash flow projections assuming the integration of any acquired technology, distribution channels and products with the Company’s products, which is of considerably greater value than utilizing each of the acquired companies’ technology, customer access or products on a stand-alone basis. The goodwill also includes value assigned to assembled workforce, which cannot be recognized as an intangible asset.

In this acquisition, the sellers provided the Company with customary representations, warranties and indemnification, which would be settled in the future if and when a breach of the contractual representation or warranty condition occurs. The impact of the acquisition of Electroforce on the Company’s revenues and net income since the acquisition date for the six months ended July 4, 2015 was immaterial.

5 Goodwill and Other Intangibles

The carrying amount of goodwill was $353 million and $355 million at July 4, 2015 and December 31, 2014, respectively. During the six months ended July 4, 2015, the Company’s acquisitions increased goodwill by $1 million (see Note 4) and the effect of foreign currency translation decreased goodwill by $3 million.

The Company’s intangible assets included in the consolidated balance sheets are detailed as follows (in thousands):

During the six months ended July 4, 2015, the Company acquired $4 million of purchased intangibles as a result of the acquisition of Electroforce (see Note 4). During the six months ended July 4, 2015, the effect of foreign currency translation decreased the gross carrying value of intangible assets and accumulated amortization for intangible assets by $33 million and $19 million, respectively. Amortization expense for intangible assets was $11 million and $12 million for the three months ended July 4, 2015 and June 28, 2014, respectively. Amortization expense for intangible assets was $22 million and $24 million for the six months ended July 4, 2015 and June 28, 2014, respectively. Amortization expense for intangible assets is estimated to be approximately $44 million per year for each of the next five years.

6 Debt

In June 2013, the Company entered into a credit agreement that provides for a $1.1 billion revolving facility and a $300 million term loan facility. In April 2015, Waters entered into an amendment to this agreement (the “Amended Credit Agreement”). The Amended Credit Agreement provides for an increase of the revolving commitments from $1.1 billion to $1.3 billion and extends the maturity of the original credit agreement from June 25, 2018 until April 23, 2020. The Company plans to use future proceeds from the revolving facility for general corporate purposes.

The interest rates applicable to the Amended Credit Agreement are, at the Company’s option, equal to either the alternate base rate calculated daily (which is a rate per annum equal to the greatest of (a) the prime rate in effect on

12

##### Table of Contents

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) – (Continued)

such day, (b) the federal funds effective rate in effect on such day plus 1/2% per annum, or (c) the adjusted LIBO rate on such day (or if such day is not a business day, the immediately preceding business day) for a deposit in U.S. dollars with a maturity of one month plus 1% per annum) or the applicable 1, 2, 3 or 6 month adjusted LIBO rate, in each case, plus an interest rate margin based upon the Company’s leverage ratio, which can range between 0 to 12.5 basis points for alternate base rate loans and between 80 basis points and 117.5 basis points for adjusted LIBO rate loans. The facility fee on the Amended Credit Agreement ranges between 7.5 basis points and 20 basis points. The Amended Credit Agreement requires that the Company comply with an interest coverage ratio test of not less than 3.50:1 as of the end of any fiscal quarter for any period of four consecutive fiscal quarters and a leverage ratio test of not more than 3.50:1 as of the end of any fiscal quarter. In addition, the Amended Credit Agreement includes negative covenants, affirmative covenants, representations and warranties and events of default that are customary for investment grade credit facilities.

At July 4, 2015, $125 million of the outstanding portion of the revolving facility was classified as short-term liabilities in the consolidated balance sheet due to the fact that the Company expects to repay this portion of the borrowing under the revolving line of credit within the next twelve months. The remaining $635 million of the outstanding portion of the revolving facility was classified as long-term liabilities in the consolidated balance sheet, as this portion is not expected to be repaid within the next twelve months.

As of July 4, 2015 and December 31, 2014, the Company had a total of $500 million and $600 million of outstanding senior unsecured notes, respectively. Interest on the fixed rate senior unsecured notes is payable semi-annually each year. Interest on the floating rate senior unsecured notes is payable quarterly. The Company may prepay all or some of the senior unsecured notes at any time in an amount not less than 10% of the aggregate principal amount outstanding, plus the applicable make-whole amount or prepayment premium for Series H senior unsecured notes. In the event of a change in control of the Company (as defined in the note purchase agreement), the Company may be required to prepay the senior unsecured notes at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest. These senior unsecured notes require that the Company comply with an interest coverage ratio test of not less than 3.50:1 for any period of four consecutive fiscal quarters and a leverage ratio test of not more than 3.50:1 as of the end of any fiscal quarter. In addition, these senior unsecured notes include customary negative covenants, affirmative covenants, representations and warranties and events of default.

interest rates applicable to the senior unsecured notes and credit agreement borrowings collectively were 2.09% and 2.31% at July 4, 2015 and December 31, 2014, respectively. As of July 4, 2015, the Company was in compliance with all debt covenants.

The Company and its foreign subsidiaries also had available short-term lines of credit totaling $86 million and $88 million at July 4, 2015 and December 31, 2014, respectively, for the purpose of short-term borrowing and issuance of commercial guarantees. At July 4, 2015 and December 31, 2014, the weighted-average interest rates applicable to these short-term borrowings were 1.25% and 1.48%, respectively.

7 Income Taxes

The Company’s effective tax rate was 14.6% and 13.9% for the three months ended July 4, 2015 and June 28, 2014, respectively. The Company’s effective tax rate was 14.9% and 14.4% for the six months ended July 4, 2015 and June 28, 2014, respectively. The differences between the effective tax rates for 2015 as compared to 2014 were primarily attributable to differences in the proportionate amounts of pre-tax income recognized in jurisdictions with different effective tax rates.

The Company accounts for its uncertain tax return reporting positions in accordance with the accounting standards for income taxes, which require financial statement reporting of the expected future tax consequences of uncertain tax reporting positions on the presumption that all concerned tax authorities possess full knowledge of those reporting positions, as well as all of the pertinent facts and circumstances, but prohibit any discounting of unrecognized tax benefits associated with those reporting positions for the time value of money.

The following is a summary of the activity of the Company’s unrecognized tax benefits for the six months ended July 4, 2015 and June 28, 2014 (in thousands):

|  | July 4, 2015 |  |  | June 28, 2014 |
Balance at the beginning of the period |  | $ | 19,596 |  |  | $ | 24,716 |
Net changes in uncertain tax benefits |  |  | 57 |  |  |  | (1,952 | )
Balance at the end of the period |  | $ | 19,653 |  |  | $ | 22,764 |

With limited exceptions, the Company is no longer subject to tax audit examinations in significant jurisdictions for the years ended on or before December 31, 2009. However, carryforward attributes that were generated in years beginning on or before January 1, 2010 may still be adjusted upon examination by tax authorities if the attributes are utilized. The Company continuously monitors the lapsing of statutes of limitations on potential tax assessments for related changes in the measurement of unrecognized tax benefits, related net interest and penalties, and deferred tax assets and liabilities. As of July 4, 2015, the Company expects to record additional reductions in the measurement of its unrecognized tax benefits and related net interest and penalties of approximately $5 million within the next twelve months due to the lapsing of statutes of limitations on potential tax assessments. The Company does not expect to record any other material reductions in the measurement of its unrecognized tax benefits within the next twelve months.

8 Stock-Based Compensation

The Company maintains various shareholder-approved, stock-based compensation plans which allow for the issuance of incentive or non-qualified stock options, stock appreciation rights, restricted stock or other types of awards (e.g. restricted stock units).

The Company accounts for stock-based compensation costs in accordance with the accounting standards for stock-based compensation, which require that all share-based payments to employees be recognized in the statements of operations based on their fair values. The Company recognizes the expense using the straight-line attribution method. The stock-based compensation expense recognized in the consolidated statements of operations is based on awards that ultimately are expected to vest; therefore, the amount of expense has been reduced for estimated forfeitures. The stock-based compensation accounting standards require forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on historical experience. If actual results differ significantly from these estimates, stock-based compensation expense and the Company’s results of operations could be materially impacted. In addition, if the

Company employs different assumptions in the application of these standards, the compensation expense that the Company records in the future periods may differ significantly from what the Company has recorded in the current period.

The consolidated statements of operations for the three and six months ended July 4, 2015 and June 28, 2014 include the following stock-based compensation expense related to stock option awards, restricted stock, restricted stock unit awards and the employee stock purchase plan (in thousands):

|  | Three Months Ended |  |  | Six Months Ended |

Total stock-based compensation |  | $ | 8,155 |  |  | $ | 8,224 |  |  | $ | 16,610 |  |  | $ | 16,353 |

Stock Options

In determining the fair value of the stock options, the Company makes a variety of assumptions and estimates, including volatility measures, expected yields and expected stock option lives. The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model. The Company uses implied volatility on its publicly-traded options as the basis for its estimate of expected volatility. The Company believes that implied volatility is the most appropriate indicator of expected volatility because it is generally reflective of historical volatility and expectations of how future volatility will differ from historical volatility. The expected life assumption for grants is based on historical experience for the population of non-qualified stock optionees. The risk-free interest rate is the yield currently available on U.S. Treasury zero-coupon issues with a remaining term approximating the expected term used as the input to the Black-Scholes model. The relevant data used to determine the value of the stock options granted during the six months ended July 4, 2015 and June 28, 2014 are as follows:

11 Business Segment Information

The Company’s business activities, for which discrete financial information is available, are regularly reviewed and evaluated by the chief operating decision maker. As a result of this evaluation, the Company determined that it has two operating segments: Waters Division and TA Division.

Waters Division is primarily in the business of designing, manufacturing, distributing and servicing LC and MS instruments, columns and other chemistry consumables that can be integrated and used along with other analytical instruments. TA Division is primarily in the business of designing, manufacturing, distributing and servicing thermal analysis, rheometry and calorimetry instruments. The Company’s two divisions are its operating segments and each has similar economic characteristics; product processes; products and services; types and classes of customers; methods of distribution and regulatory environments. Because of these similarities, the two segments have been aggregated into one reporting segment for financial statement purposes. Please refer to the consolidated financial statements for financial information regarding the one reportable segment of the Company.

12 Recent Accounting Standard Changes and Developments

Recently Issued Accounting Standards

In May 2014, amended accounting guidance was issued regarding the recognition of revenue from contracts with customers. The objective of this guidance is to significantly enhance comparability and clarify principles of revenue recognition practices across entities, industries, jurisdictions and capital markets. This guidance was originally effective for annual and interim reporting periods beginning after December 15, 2016; however, the Financial Accounting Standards Board has voted to delay the effective period by one year. Adoption prior to December 15, 2016 is not permitted. The Company is currently evaluating its adoption method and the potential impact that the adoption of this standard will have on the Company’s financial position, results of operations and cash flows.

In April 2015, accounting guidance was issued which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability. This guidance is effective for annual and interim reporting periods beginning after December 15, 2015 and early adoption is permitted. The Company is currently evaluating the potential impact that the adoption of this standard will have on the Company’s financial position, results of operations or cash flows.

Sales in the second quarter of 2015 grew 3% as the strong demand for the Company’s products and services were negatively affected by the foreign currency translation which reduced sales growth by 7%. This decline in sales growth from foreign currency translation resulted primarily from the weakening of the Euro and Japanese yen against the U.S. dollar and reduced Europe’s and Japan’s sales by 16% and 18%, respectively. The 2015 sales growth for the quarter was broad-based across all customer end-markets and driven by increases in the U.S., China and India.

Sales in the first half of 2015 grew 5% despite the significant negative effect of foreign currency translation, which reduced sales growth by 7% year-to-date. The 2015 sales growth for the first half benefited from the Company’s life science, industrial chemical, nutritional safety and environmental customers, especially in the U.S., China and India. Sales growth in 2015 also benefited by an estimated 2% from additional calendar days in the first half of 2015 as compared with the first half of 2014. The negative impact from foreign currency translation resulted primarily from the weakening of the Euro and Japanese yen against the U.S. dollar, which reduced Europe’s and Japan’s sales by 16% and 15%, respectively. Acquisitions had a minimal impact on sales year-to-date.

In 2015, instrument system sales grew 4% and 5% for the quarter and year-to-date, respectively, and recurring revenues (combined chemistry consumable and service sales) increased 1% and 4%, respectively. Sales growth for both instrument systems and recurring revenues were negatively impacted by foreign currency translation. The increase in instrument system sales can be attributed to the higher customer demand for LC and LC-MS instrument systems and the increase in recurring revenues is primarily due to the increase in service sales resulting from a larger installed customer base.

The Company’s sales growth by customer end-market for both the quarter and year-to-date were negatively impacted by the European and Japanese foreign currency translation discussed above. Despite this decline in sales, the Company’s customer end-market sales were able to grow as follows:

| • |  | Sales to life science customers grew by 3% and 6% for the quarter and year-to-date, respectively, with double-digit sales growth in all regions, except Europe and Japan.

| • |  | Combined sales to industrial chemical, nutritional safety and environmental customers increased by 2% and 5% for the quarter and year-to-date, respectively. Sales in the quarter were strongest in Asia, excluding Japan, while year-to-date sales were driven by the U.S. and Asia, excluding Japan.

| • |  | Combined global sales to governmental and academic customers grew by 2% for the quarter and were flat year-to-date. China sales grew at a double-digit rate for both the quarter and year-to-date and Japan showed sales growth in the quarter.

The increase in gross profit dollars for both the quarter and year-to-date was primarily a result of higher sales volumes. The slight decline in the second quarter gross profit margin percentage can be attributed to the sales mix resulting from a higher level of instrument system sales. The year-to-date gross profit margin percentage was higher as a result of leverage achieved on higher sales volumes and the favorable effects of foreign currency translation on operating costs of the Company’s European manufacturing and distribution facilities. Based on current foreign currency exchange rates and forecasts, the Company estimates that the full year impact of foreign currency translation will negatively impact sales by approximately 6% and have a negative impact on gross profit.

Selling and administrative expenses decreased 7% and 6% for the quarter and year-to-date, respectively, from the favorable effect of foreign currency translation and the impact of a $4 million write-down in fair value of a building held for sale in the prior year. In addition, year-to-date selling and administrative expenses included $6 million of severance costs incurred in the first quarter of 2014 related to a reduction in workforce.

The increase in research and development expenses in both the quarter and year-to-date was primarily a result of increased spending on new products and the development of new product initiatives, which was somewhat offset by favorable effects of foreign currency translation.

Net income per diluted share for both the quarter and year-to-date benefited from an increase in sales and fewer shares outstanding due to additional share repurchases. Foreign currency translation decreased net income per diluted share by approximately $0.13 in the quarter and approximately $0.21 year-to-date.

Net cash provided by operating activities for the first half of 2015 was $268 million and $222 million in 2015 and 2014, respectively. The $46 million increase was primarily a result of higher sales volumes and the timing of payments to vendors and collection of receivables from customers, as well as the additional days in the first quarter of 2015. Within cash flows used in investing activities, capital expenditures related to property, plant, equipment and software capitalization were $45 million and $44 million for 2015 and 2014, respectively.

On May 22, 2015, the Company acquired the net assets of the Electroforce business of the Bose Corporation (“Electroforce”), for approximately $9 million in cash. Electroforce is a manufacturer of dynamic mechanical testing systems used to characterize medical devices, biologic and engineered materials. This acquisition is not expected to have a significant impact on the Company’s sales and profits over the next twelve months.

Within cash flows used in financing activities, the Company received $25 million and $41 million of proceeds from stock plans in 2015 and 2014, respectively. Fluctuations in these amounts were primarily attributable to changes in

the Company’s stock price and the expiration of stock option grants. In May 2014, the Company’s Board of Directors authorized the Company to repurchase up to $750 million of its outstanding common stock over a three-year period and authorized the extension of the May 2012 program until May 2015. The Company repurchased $165 million and $178 million of the Company’s outstanding common stock in 2015 and 2014, respectively, under the May 2012 and May 2014 authorizations.

In April 2015, Waters entered into an amendment to the credit agreement dated June 2013. The amended credit agreement provides for an increase of the revolving commitments from $1.1 billion to $1.3 billion and extends the maturity of the original credit agreement from June 25, 2018 until April 23, 2020. The Company plans to use future proceeds from the revolving facility for general corporate purposes.

The increase in sales in the U.S. for the quarter and year-to-date were driven by Waters instrument system sales to life science customers. The decrease in Europe’s sales growth was primarily due to the negative effects of foreign currency translation, which reduced sales growth by 16% in both the quarter and year-to-date. China’s sales growth was broad-based across all product lines and customer classes. Japan’s sales were negatively impacted by foreign currency translation, which decreased sales by 18% and 15% for the quarter and year-to-date, respectively. The increase in sales in both the quarter and year-to-date in the rest of Asia was broad-based across all product and customer classes. The decline in sales in the rest of the world was tempered by double-digit sales growth to life science customers in both the quarter and year-to-date.

Waters instrument system sales (LC and LC-MS) increased in the quarter and year-to-date, primarily due to stronger demand for instrument systems from life science, industrial chemical, nutritional safety and environmental customers. The increase in recurring revenues for both the quarter and year-to-date primarily resulted from a combination of a higher utilization rate of installed instrument systems and a higher base of installed instruments. In addition, the first half of 2015 had additional calendar days as compared with the first half of 2014. The effect of foreign currency translation decreased sales for the Waters Division by 8%.

Waters Division sales increased 10% and 15% in the U.S. for the quarter and year-to-date, respectively. Europe sales decreased 11% and 8% for the quarter and year-to-date, respectively, primarily due to the negative effect of foreign currency translation, which decreased sales by 16% and 17%, respectively. Total Asia sales increased 14% and 11% for the quarter and year-to-date, respectively, with sales in China increasing 27% and 21%, respectively. Japan sales decreased 13% in both the quarter and year-to-date, primarily due to the effects of foreign currency translation, while sales in the rest of Asia increased 22% and 20%. Sales in the rest of the world increased 9% and 3% in the quarter and year-to-date, respectively.

TA instrument system sales decreased 5% in the quarter due to the negative effect of foreign currency translation. TA service sales increased for both the quarter and year-to-date due to sales of service plans and billings to a higher installed base of customers. In addition, the first half of 2015 had additional calendar days as compared with the first half of 2014. The effect of foreign currency translation decreased TA’s total sales by 5% for both the quarter and year-to-date. TA had double-digit sales growth in Asia, excluding Japan, which was offset by declines in Europe and Japan, primarily due to the negative effects of foreign currency translation. Recent acquisitions added 4% and 2% to sales growth for the quarter and year-to-date, respectively.

Gross Profit

Gross profit increased 2% and 7% for the quarter and year-to-date, respectively, primarily as a result of benefits from sales mix, leverage achieved on higher sales volumes and the favorable effect of foreign currency translation on operating costs of the Company’s European manufacturing and distribution facilities. Gross profit as a percentage of sales for the quarter was also impacted by the factors discussed above.

22

##### Table of Contents

Gross profit as a percentage of sales is affected by many factors, including, but not limited to, foreign currency translation, product mix, price, product costs of instrument systems and amortization of software platforms. The Company expects that the impact of foreign currency translation will negatively affect gross profit for the remainder of 2015, based on current exchange rates.

Selling and Administrative Expenses

Selling and administrative expenses decreased 7% and 6% for the quarter and year-to-date, respectively, from the favorable effect of foreign currency translation and the impact of a $4 million impairment charge related to a write-down in the fair value of a building held for sale in the U.K, which was recorded in the second quarter of 2014. Year-to-date, selling and administrative expenses were also lower due to $6 million of severance-related costs incurred in the first quarter of 2014 in connection with a reduction in workforce. As a percentage of net sales, selling and administrative expenses were 24.8% and 25.4% for the 2015 quarter and year-to-date, respectively, and 27.4% and 28.3% for the 2014 quarter and year-to-date, respectively.

Research and Development Expenses

Research and development expenses increased 13% and 15% for the quarter and year-to-date, respectively, primarily as a result of additional headcount, merit compensation and costs associated with new products and the development of new product initiatives. These increases were somewhat offset by favorable effects of foreign currency translation.

Interest Expense, Net

The increase in net interest expense for both the quarter and year-to-date was primarily attributable to an increase average borrowings, offset slightly by income earned on an increase in average cash, cash equivalents and investments.

Provision for Income Taxes

The four principal jurisdictions in which the Company manufactures are the U.S., Ireland, the United Kingdom and Singapore, where the marginal effective tax rates were approximately 37.5%, 12.5%, 20.25% and 0%, respectively, as of July 4, 2015. In July 2015 (fiscal third quarter), the Company entered into a new agreement with Singapore tax authorities that extended a 0% contractual tax rate through March 2021. The contractual tax rate is dependent upon achievement of certain contractual milestones, which the Company expects to meet. The current statutory tax rate in Singapore is 17%. The Company’s effective tax rate is influenced by many significant factors, including, but not limited to, the wide range of income tax rates in jurisdictions in which the Company operates; sales volumes and profit levels in each tax jurisdiction; changes in tax laws, tax rates and policies; the outcome of various ongoing tax audit examinations; and the impact of foreign currency transactions and translation. As a result of variability in these factors, the Company’s effective tax rates in the future may not be similar to the effective tax rates for the current or prior year.

The Company’s effective tax rate for the quarter was 14.6% and 13.9% for 2015 and 2014, respectively. The Company’s effective tax rate year-to-date was 14.9% and 14.4% for 2015 and 2014, respectively. The differences between the effective tax rates for 2015 as compared to 2014 were primarily attributable to differences in the proportionate amounts of pre-tax income recognized in jurisdictions with different effective tax rates.

Cash Flow from Operating Activities

Net cash provided by operating activities was $268 million and $222 million in the six months ended July 4, 2015 and June 28, 2014, respectively. The changes within net cash provided by operating activities in 2015 as compared to 2014 include the following significant changes in the sources and uses of net cash provided by operating activities, aside from the increase in net income:

| • |  | The change in accounts receivable in 2015 compared to 2014 was primarily attributable to timing of shipments and payments made by customers. Days-sales-outstanding (“DSO”) decreased to 75 days at July 4, 2015 from 76 days at June 28, 2014.

| • |  | The change in inventory in both 2015 and 2014 is primarily attributable to the additional inventory ramp up for new products to be launched later this year.

| • |  | The 2015 and 2014 change in accounts payable and other current liabilities was a result of timing of payments to vendors.

| • |  | Net cash provided from deferred revenue and customer advances in both 2015 and 2014 was a result of the higher installed base of customers renewing annual service contracts.

| • |  | Other changes were attributable to variation in the timing of various provisions, expenditures, prepaid income taxes and accruals in other current assets, other assets and other liabilities. In addition, the Company made one-time contributions totaling $21 million to certain Non-U.S. pension plans during 2014.

Cash Used in Investing Activities

Year-to-date, net cash used in investing activities totaled $265 million and $174 million in 2015 and 2014, respectively. Additions to fixed assets and capitalized software were $45 million and $44 million year-to-date in 2015 and 2014, respectively. During 2015 and 2014, the Company purchased $1,328 million and $1,179 million of investments year-to-date, while $1,118 million and $1,053 million of investments matured, respectively. Business acquisitions, net of cash acquired, were $9 million and $4 million year-to-date in 2015 and 2014, respectively.

Cash Used in Financing Activities

In April 2015, Waters entered into an amendment to the credit agreement dated June 2013. The amended credit agreement provides for an increase of the revolving commitments from $1.1 billion to $1.3 billion and extends the maturity of the original credit agreement from June 25, 2018 until April 23, 2020. The Company plans to use future proceeds from the revolving facility for general corporate purposes.

##### Table of Contents

Year-to-date, the Company’s total debt borrowings increased by $95 million and $70 million in 2015 and 2014, respectively. As of July 4, 2015, the Company had a total of $1,560 million in outstanding debt, which consisted of $500 million in outstanding senior unsecured notes, $300 million borrowed under the term loan facility under the 2015 Credit Agreement and $760 million borrowed under revolving credit facility under the 2015 Credit Agreement. At July 4, 2015, $125 million of the outstanding portion of the revolving facility was classified as short-term liabilities in the consolidated balance sheet due to the fact that the Company expects to repay this portion of the borrowing under the revolving line of credit within the next twelve months. The remaining $635 million of the outstanding portion of the revolving facility was classified as long-term liabilities in the consolidated balance sheet, as this portion is not expected to be repaid within the next twelve months. As of July 4, 2015, the Company had a total amount available to borrow under the 2015 Credit Agreement of $538 million after outstanding letters of credit.

In May 2014, the Company’s Board of Directors authorized the Company to repurchase up to $750 million of its outstanding common stock over a three-year period and authorized the extension of the May 2012 program until May 2015. During the first six months of 2015 and 2014, the Company repurchased 1.3 million and 1.7 million shares of the Company’s outstanding common stock at a cost of $165 million and $178 million, respectively, under the May 2012 and May 2014 authorizations. As of July 4, 2015, the Company had a total of $604 million authorized for future repurchases under the May 2014 plan. In addition, the Company repurchased $6 million and $7 million of common stock related to the vesting of restricted stock units during 2015 and 2014, respectively.

The Company received $25 million and $41 million of proceeds from the exercise of stock options and the purchase of shares pursuant to the Company’s employee stock purchase plan in 2015 and 2014, respectively.

The Company had cash, cash equivalents and investments of $2,209 million as of July 4, 2015. The majority of the Company’s cash, cash equivalents and investments are generated from foreign operations, with $2,162 million held by foreign subsidiaries at July 4, 2015. Due to the fact that most of the Company’s cash, cash equivalents and investments are held outside of the U.S., the Company must manage and maintain sufficient levels of cash flow in the U.S. to fund operations and capital expenditures, service debt interest, finance potential U.S. acquisitions and continue the authorized stock repurchase program in the U.S. These U.S. cash requirements are managed by the Company’s cash flow from U.S. operations and the use of the Company’s revolving credit facility.

Management believes, as of the date of this report, that its financial position, particularly in the U.S., along with expected future cash flows from earnings based on historical trends and the ability to raise funds from external sources and the borrowing capacity from existing, committed credit facilities, will be sufficient to service debt and fund working capital and capital spending requirements, authorized share repurchase amounts and potential acquisitions. In addition, there have been no recent significant changes to the Company’s financial position, nor are there any anticipated changes, to warrant a material adjustment related to indefinitely reinvested foreign earnings.

Many of these statements appear, in particular, under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part I, Item 2 of this Quarterly Report on Form 10-Q. Statements that are not statements of historical fact may be deemed forward-looking statements. You can identify these forward-looking statements by the use of the words “feels”, “believes”, “anticipates”, “plans”, “expects”, “may”, “will”, “would”, “intends”, “suggests”, “appears”, “estimates”, “projects”, “should” and similar expressions, whether in the negative or affirmative. These statements are subject to various risks and uncertainties, many of which are outside the control of the Company, including, and without limitation:

| • |  | The risks inherent in the transition of chief executive officer as the Company has announced a new chief executive officer effective September 2015 upon the retirement of the current chief executive officer.

| • |  | Foreign exchange rate fluctuations that could adversely affect translation of the Company’s future sales, financial operating results and the condition of non-U.S. operations, especially when a currency weakens against the U.S. dollar.

| • |  | Current global economic, sovereign and political conditions and uncertainties, particularly regarding the effect of the Chinese government’s ongoing tightening of restrictions on procurement by government-funded customers; the Company’s ability to access capital and maintain liquidity in volatile market conditions of customers; changes in timing and demand by the Company’s customers and various market sectors, particularly

| if they should reduce capital expenditures or are unable to obtain funding, as in the cases of governmental, academic and research institutions; the effect of mergers and acquisitions on customer demand; and the Company’s ability to sustain and enhance service.

| • |  | Negative industry trends; changes in the competitive landscape as a result of changes in ownership, mergers and continued consolidation among the Company’s competitors; introduction of competing products by other companies and loss of market share; pressures on prices from customers or resulting from competition; regulatory, economic and competitive obstacles to new product introductions; lack of acceptance of new products; expansion of our business in developing markets; spending by certain end-markets; and ability to obtain alternative sources for components and modules; and the possibility that future sales of new products, which trigger contingent purchase payments, may exceed our expectations.

| • |  | Increased regulatory burdens as the Company’s business evolves, especially with respect to the Food and Drug Administration and Environmental Protection Agency, among others, as well as regulatory, environmental and logistical obstacles affecting the distribution of the Company’s products, completion of purchase order documentation by our customers and ability of customers to obtain letters of credit or other financing alternatives.

| • |  | Risks associated with lawsuits, particularly involving claims for infringement of patents and other intellectual property rights.

| • |  | The impact and costs incurred from changes in accounting principles and practices; the impact and costs of changes in statutory or contractual tax rates; shifts in taxable income in jurisdictions with different effective tax rates; and the outcome of and costs associated with ongoing and future tax audit examinations or changes in respective country legislation affecting the Company’s effective rates.

Certain of these and other factors are discussed under the heading “Risk Factors” under Part I, Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, as filed with the SEC on February 27, 2015.
