Progress With Acquisition Strategy: Quest Diagnostics continues to drive growth through value-creating and strategically aligned acquisitions, mainly focusing on accretive outreach purchases and other independent labs. These also position the company to expand into key geographic areas across the United States, where the influence of health systems had previously limited their reach. In 2024, Quest Diagnostics completed eight acquisitions, all of which align with its criteria for growth, profitability and returns.

The addition of LifeLabs boosted Quest Diagnostics’ DIS revenues in the fourth quarter of 2024, strengthening its foothold in the Canadian market and creating new growth opportunities. The company also completed the acquisition of outreach lab assets from Ohio Health and University Hospitals, two leading non-profit health systems in Ohio. This year, the company plans to moderate its acquisition pace and focus on driving growth from these completed transactions. 

Strategic Imperative to Drive Operational Excellence: Quest Diagnostics strategically deploys automation and AI to improve quality, service, efficiency and the workforce experience. In 2024, its cost excellence program, Invigorate, delivered 3% annual cost savings and productivity enhancements while achieving significant improvements in retention rates across various job categories. The Clifton, NJ, lab serves as a hub for many of Quest Diagnostics’ automation and AI solutions, including a proprietary system for enhanced tuberculosis testing and an accessioning solution that speeds requisition processing. The company also deployed a third-party AI solution to enhance parasitology screening by identifying likely positive specimens for further review.

Concerns for DGX

Industry Risks That May Affect the Stock: Amid the continuing evolution of the healthcare industry, the company’s operations are exposed to several inherent risks, such as fluctuations in healthcare utilization rate, softer testing volumes, commercial pricing pressure and reimbursement headwinds. The clinical testing industry is also subject to seasonal fluctuations. Clinical testing orders generated from clinician offices, hospitals, employers and consumers can be affected by changes in the U.S. economy and regulatory environment.

Competitive Landscape: Quest Diagnostics faces intense competition, primarily from LabCorp, other commercial laboratories and hospitals. While pricing is an important factor in choosing a testing lab, hospital-affiliated physicians expect a high level of service, including an accurate and rapid turnaround of testing results. As a result, Quest Diagnostics and other commercial labs compete with hospital-affiliated labs, primarily based on the quality of service.
