Non-GAAP Financial Measures

This press release contains financial measures, such as constant currency growth rate, adjusted operating income, adjusted net income, adjusted earnings per diluted share and free cash flow, among others, which are considered“non-GAAP” financial measures under applicable U.S. Securities and Exchange Commission rules and regulations.

The Company’s definition of thesenon-GAAP measures may differ from similarly titled measures used by others. Thenon-GAAP financial measures used in this press release adjust for specified items that can be highly variable or difficult to predict. The Company generally uses thesenon-GAAP financial measures to facilitate management’s financial and operational decision-making, including evaluation of Waters Corporation’s historical operating results, comparison to competitors’ operating results and determination of management incentive compensation.

(1) The Company adopted new accounting guidance which requires that an employer disaggregate the service cost component from other components of net benefit cost. As a result of the adoption of this standard, the components of net periodic benefit cost other than the service cost component are included in other income in the consolidated statements of operations and all previous periods have been adjusted accordingly.

(2) In May 2018, the Company’s board of directors approved the termination of its frozen U.S. defined benefit pension plans. In December 2018, the Company settled a pension plan obligation by makinglump-sum cash payments and purchasing annuity contracts for participants to permanently extinguish the pension plan’s obligations. As a result, the Company recorded a $46 million charge, which consisted of a $6 million cash contribution to the plan and a $40 millionnon-cash charge related to the reversal of unrecognized actuarial losses recorded in accumulated other comprehensive income in the stockholders’ equity.

(3) The provision for income taxes for the three and twelve months ended December 31, 2017 included a $550 million estimate for the impact of the enactment of the Tax Cuts and Jobs Act. The provision for income taxes for the three and twelve months ended December 31, 2018 included a $5 million benefit and a $1 million expense, respectively, related to U.S. tax reform. The provisions include: (1) an adjustment to our 2017 year end accrual for the toll charge resulting from federal proposed regulations and other state guidance and (2) the tax that results from the change in foreign currency exchange rates on the earnings taxed on December 31, 2017 under the Tax Cuts and Jobs Act as compared with the foreign currency exchange rates on the date of distribution of assets into the U.S.

(h) Thenon-cash expense associated with accelerating the vesting of certain stock awards was excluded as the Company believes these expenses are not indicative of normal operating costs.

(a)   In the fourth quarter of 2017, the Company recorded a $550 million income tax provision for an estimate of the impact of the enactment of the Tax Cuts and Jobs Act (2017 Tax Act), which was signed into law on December 22, 2017. The $550 million income tax provision primarily consists of an estimated U.S. transition tax as well as estimated income tax provisions for state and withholding taxes and a charge associated with the remeasurement of the Company’s deferred tax assets and liabilities from 35% to the new U.S. corporate income tax rate of 21%.

(b)   The Company defines free cash flow as net cash flow from operations accounted for under GAAP less capital expenditures and software capitalizations plus or minus any unusual and non recurring items. Free cash flow is not a GAAP measurement and may not be comparable to free cash flow reported by other companies.

Constant currency growth rates are a non-GAAP financial measure that measures the change in net sales between current and prior year periods, ignoring the impact of foreign currency exchange rates during the current period. These amounts are estimated at the current foreign currency exchange rates and based on the forecasted geographical sales in local currency, as well as an assessment of market conditions as of today, and may differ significantly from actual results.

These forward-looking adjustment estimates do not reflect future gains and charges that are inherently difficult to predict and estimate due to their unknown timing, effect and/or significance.
