The future of COVID - 19 testing  The virus isn’t going away anytime soon  Test volumes will decrease over time in 2021  We’re moving from primarily clinical uses to increased testing for “Return - to - Life”  Serology testing could play a role in assessing immune response  Like influenza, COVID - 19 infectious disease testing will be a permanent part of our test menu

COVID - 19 has underscored the importance of partnerships

Appendix Non - GAAP Reconciliations

Note on Non - GAAP Financial Measures The non-GAAP measures for (i) adjusted diluted EPS from continuing operations, (ii) free cash flow and (iii) contribution margin are presented because management believes those measures are useful adjuncts to measures under the accounting principles generally accepted in the United States (“GAAP”). As used in this presentation the term (i) “adjusted” refers to non-GAAP measures that exclude special items such as restructuring and integration charges, certain financial impacts resulting from the COVID-19 pandemic, amortization expense, excess tax benefit associated with stock-based compensation, a gain on remeasurement of an equity interest, costs associated with donations, contributions and other financial support through Quest for Health Equity, the company's recently announced initiative with the Quest Diagnostics Foundation to reduce health disparities in underserved communities, the gain on the sale and leaseback of a property, and other items; (ii) “free cash flow” refers to operating cash flows less capital expenditures and (iii) “contribution margin” refers to: (a) revenues less direct incremental costs related to such revenues, divided by: (b) such revenues. The company has provided compound annual growth rate projections of 7 - 9% for adjusted diluted EPS and free cash flow, which are non - GAAP measures. The company is unable to present a reconciliation of these non - GAAP measures to the most comparable GAAP measure due to the inherent uncertainty and variability in the nature and amount of special items referenced above. Non - GAAP measures should not be considered as an alternative to the corresponding measures determined under GAAP. Management may use these non - GAAP measures to evaluate our performance period over period and relative to competitors, to analyze the underlying trends in our business, to establish operational budgets and forecasts and for incenti ve compensation purposes. We believe that these non - GAAP measures are useful to investors and analysts to evaluate our performance period over period and relative to competitors, as well as to analyze the underlying trends in our business and t o a ssess our performance. The following tables reconcile reported GAAP measures to non - GAAP measures.

Adjusted Diluted EPS from Continuing Operations  The following table reconciles adjusted diluted earnings per share from continuing operations ("Diluted EPS") to reported res ult s under GAAP.

Adjusted Diluted EPS from Continuing Operations a) For the twelve months ended December 31, 2020 and 2019, represents costs primarily associated with systems conversions and in teg ration incurred in connection with further restructuring and integrating our business. For the twelve months ended December 31, 2018, represents costs primarily associate d with workforce reductions, systems conversions and integration incurred in connection with further restructuring and integrating our business. Income tax impacts were primarily calculated using combined statutory tax rates of 25.5%. b) For the twelve months ended December 31, 2020, principally includes expense associated with payments to eligible employees to he lp offset expenses they incurred as a result of COVID - 19, incremental costs incurred primarily to protect the health and safety of our employees and customers, and ce rtain asset impairment charges. Income tax impacts were primarily calculated using combined statutory tax rates of 25.5%. c) For the twelve months ended December 31, 2020, represents a pre - tax gain of $70 million based on the difference between the fair value and the carrying value of an equity interest. On August 1, 2020, we completed the acquisition of the remaining 56% interest in Mid America Clinical Laboratories, LL C ("MACL") from our joint venture partners. As a result of the transaction, we remeasured our previously held minority interest in MACL to fair value and recognized a gain. I ncome tax expense was calculated based on an effective income tax rate on the transaction of 11.8%, which is lower than the statutory income tax rate due to a permanent d iff erence in the financial reporting and tax basis of goodwill. d) For the twelve months ended December 31, 2020, includes a gain recognized by an equity method investee to adjust certain of its investments to fair value, which was offset by a loss on retirement of debt, and, to a lesser extent, costs associated with Quest for Health Equity, our recently announc ed initiative with the Quest Diagnostics Foundation to reduce health disparities in underserved communities. For the twelve months ended December 31, 2019, primarily represents a gain associated with the sale and leaseback of a property, a gain associated with the decrease in the fair value of the contingent consideration accruals associated with pr evious acquisitions, and a gain associated with proceeds from an insurance claim for hurricane related losses, partially offset by costs incurred related to a data security inc ident and non - cash asset impairment charges. For the twelve months ended December 31, 2018, primarily represents costs incurred related to certain legal matters and a loss on th e sale of a foreign subsidiary, which were partially offset by a gain associated with the decrease in the fair value of the contingent consideration accrual associated wit h a previous acquisition and proceeds from an insurance claim for hurricane related losses. Income tax impacts were primarily calculated using combined statutory tax rates o f 25.5% for 2020, 2019 and 2018. For the gain associated with proceeds from an insurance claim for hurricane related losses in 2019, there was no net income tax expense as we were able to utilize net operating loss carryforwards for which a valuation allowance had previously been established. For the gain in 2019 associated with the decre ase in the fair value of the contingent consideration accruals associated with previous acquisitions, there was no net income tax expense related to acquisitions for wh ich the gain was non - taxable. e) For the twelve months ended December 31, 2018, represents an income tax benefit associated with a change in a tax return acco unt ing method that enabled us to accelerate the deduction of certain expenses on our 2017 tax return at the federal corporate statutory income tax rate in effect during 201 7, partially offset by an income tax expense associated with finalizing the impact of the enactment of the Tax Cuts and Jobs Act of 2017.

Free Cash Flow  The following table reconciles free cash flow to the corresponding measures determined under GAAP.
