High debt levels and short-term technical weaknesses are areas to watch.

Positive Factors

Growth Prospects

Management expressed greater conviction in Quest Diagnostics' long-term growth prospects, emphasizing a strong fundamental backdrop and positive trends in healthcare and diagnostics.

Market Position

DGX has gained share in Physician Lab Services and in Hospital Lab Services, which it expects to continue, outgrowing the market in both segments.

Revenue and EPS Growth

The company expects significant revenue and EPS growth in 2025, driven by improved utilization and diagnostic innovation.

Tariff Management

Management is not concerned with tariff impacts, noting they are manageable and included in current guidance.

Negative Factors

Potential Reimbursement Cuts

The company now sees a cut to CMS reimbursement in '26 (up to 15%) as a 50% probability, which would drive a $100M headwind but enable industry consolidation and share gains.

Regulatory Compliance Costs

DGX is still expecting to incur up to the prior $10M investment needed to improve regulatory compliance.
