Quest Diagnostics to Highlight Strategic Priorities to Drive Sustainable

Growth and Deliver Long-term Shareholder Value at 2025 Investor Day

SECAUCUS, N.J., March 19, 2025 -- At a meeting with analysts and investors at its 2025 Investor Day, members of the leadership team of Quest Diagnostics (NYSE: DGX), a leading provider of diagnostic information services, will discuss the company's strategies to drive sustainable growth and deliver long-term shareholder value.

"We are confident in Quest’s ability to grow at above-market rates in our core physician and hospital channels driven by increased market access, double-digit growth in advanced diagnostics across five key clinical areas, and the contributions of strategic partnerships and acquisitions,” said Jim Davis, Chairman, CEO and President. “We expect our continuous improvement initiatives – including investments in automation, robotics, and AI – to strengthen quality, customer and employee experiences, and productivity. Further, our new Project Nova IT initiative will modernize our systems architecture and lower IT costs over the long-term. These factors are reflected in the long-term outlook we are articulating today, which anticipates revenue growth at a 4-5% CAGR and adjusted EPS growth at a 7-9% CAGR beyond 2025.”

At the meeting, members of the company’s leadership team will highlight a range of strategic initiatives that are underway, including:

Guidance for Full Year 2025

The company today reaffirmed its guidance for full year 2025, as per the table below. For the first quarter of 2025, the company now expects that worse-than-anticipated weather during the period will create a headwind to revenue of approximately $25 million and to EPS of approximately $0.10.

The additional table attached below includes reconciliations of non-GAAP adjusted measures to GAAP measures.

Note on Non-GAAP Financial Measures

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.

The company has provided a compound annual growth rate projection beyond 2025 of 7-9% for adjusted diluted EPS, which is a non-GAAP measure. The company is unable to present a reconciliation of adjusted diluted EPS to reported diluted EPS, the most comparable GAAP measure, due to the inherent uncertainty and variability in the nature and amount of special items referenced above, and the amount of these items could be significant in any of the associated periods.

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 table attached below includes reconciliations of non-GAAP adjusted measures to GAAP measures.

ADDITIONAL TABLE FOLLOWS

The outlook for adjusted diluted EPS represents management's estimates for the full year 2025 before the impact of special items. Further impacts to earnings related to special items may occur throughout 2025. 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 2025 outlook for diluted EPS under GAAP to our outlook for adjusted diluted EPS:

(a)      Represents estimated pre-tax charges of $16 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 $160 million. Income tax benefits were primarily calculated using a combined statutory income tax rate of 25.5%.

(c)      Represents estimated pre-tax net losses of $15 million, principally 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 associated with the contingent consideration accrual.
