SECAUCUS, N.J., July 23, 2024 - Quest Diagnostics Incorporated (NYSE: DGX), a leading provider of diagnostic information services, today announced financial results for the second quarter ended June 30, 2024.

"We delivered another strong quarter, with base business revenue growth of nearly 4% and total revenue growth of 2.5% as well as continued improvement in productivity and profitability in the base business,” said Jim Davis, Chairman, CEO and President. "This performance is due to growth of new physician and hospital customers, more favorable test mix that includes greater adoption of advanced diagnostics and continued strength in healthcare utilization. We also made progress improving our operational quality and efficiency through greater use of automation and AI.”

Mr. Davis added: “In addition, we are excited to announce four acquisitions that meet our criteria for growth, profitability and returns, and that will enable us to expand in strategic growth areas. Our planned acquisition of LifeLabs will position us to help this trusted lab leader grow and better serve Canada’s growing and aging population. The acquisitions we recently announced of select outreach lab assets of Allina Health in Minnesota and Wisconsin and OhioHealth in Ohio reflect our ability to partner with high-quality health systems and extend our presence in key geographies. Our recently completed PathAI Diagnostics acquisition positions us to rapidly scale digital pathology innovation to help health systems and other providers improve cancer diagnoses.”

The company updates its full year 2024 guidance as follows:

The company's updated guidance does not include the impact of the pending LifeLabs acquisition given the uncertainty around when the transaction will close. The company continues to expect to complete the transaction by the end of the year, subject to certain customary closing conditions and approvals, including Canadian regulatory approvals.

As used in this press release the term “reported” refers to measures under accounting principles generally accepted in the United States (“GAAP”). The term “adjusted” refers to non-GAAP operating performance measures that exclude special items such as restructuring and integration charges, amortization expense, excess tax benefits ("ETB") associated with stock-based compensation, gains and losses associated with changes in the carrying value of our strategic investments, and other items.

Non-GAAP adjusted measures are presented because management believes those measures are useful adjuncts to GAAP results. Non-GAAP adjusted 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 incentive 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 to assess our performance. The additional tables attached below include reconciliations of non-GAAP adjusted measures to GAAP measures.

For the Three and Six Months Ended June 30, 2024 and 2023

1)The computation of basic and diluted earnings per common share is as follows:

2)The following tables reconcile reported GAAP results to non-GAAP adjusted results:

(a)For both the three and six months ended June 30, 2024 and 2023, the pre-tax impact represents costs primarily associated with workforce reductions and integration costs incurred in connection with further restructuring and integrating our business. The following table summarizes the pre-tax impact of restructuring and integration charges on our consolidated statements of operations:

(b)For the three and six months ended June 30, 2024, the pre-tax impact primarily represents a loss associated with the increase in the fair value of the contingent consideration accrual associated with previous acquisitions. For both the three and six months ended June 30, 2023, the pre-tax impact primarily represents the impairment of a corporate facility that was held for sale. The following table summarizes the pre-tax impact of these other items on our consolidated statements of operations:

(c)For each of the three and six months ended June 30, 2024 and the six months ended June 30, 2023, the pre-tax impact represents gains and losses associated with changes in the carrying value of our strategic investments, recorded in equity in earnings of equity method investees, net of taxes.

(d)For restructuring and integration charges, gains and losses on investments, other items and amortization expense, income tax impacts, where recorded, were primarily calculated using combined statutory income tax rates of 25.5% for both 2024 and 2023.

3)The outlook for adjusted diluted EPS represents management’s estimates for the full year 2024 before the impact of special items. Further impacts to earnings related to special items may occur throughout 2024. Additionally, the amount of ETB is dependent upon employee stock option exercises and our stock price, which are difficult to predict. The following table reconciles our 2024 outlook for diluted EPS under GAAP to our outlook for adjusted diluted EPS:

(a)Represents estimated pre-tax charges of $45 million primarily associated with workforce reductions and integration costs incurred in connection with further restructuring and integrating our business. Income tax benefits were primarily calculated using a combined statutory income tax rate of 25.5%.

(b)Represents estimated pre-tax amortization expenses of $123 million. Income tax benefits were primarily calculated using a combined statutory income tax rate of 25.5%.

(c)Represents estimated pre-tax losses of $13 million primarily associated with the increase in the fair value of the contingent consideration accrual associated with previous acquisitions. No income tax benefits are recorded on the losses.

(d)Represents $9 million of pre-tax losses associated with changes in the carrying value of our strategic investments. Income tax impacts were calculated using a combined statutory income tax rate of 25.5%.
