DGX: Core Volume Momentum And New Blood Tests Will Drive Share Momentum

Key Takeaways

• Growth in advanced diagnostics, consumer wellness demand, and accretive acquisitions is driving higher test volumes, revenue, and expanding geographic reach.
  
• Automation, AI adoption, and health data analytics are improving productivity, margins, and positioning the company for sustainable, data-driven revenue opportunities.
  
• Regulatory reimbursement risks, shifting payer mix, healthcare coverage changes, and rising expenses threaten Quest's revenue growth, pricing power, and margin expansion amidst intensifying market competition.

Catalysts

Provides diagnostic testing and services in the United States and internationally.

• Ongoing growth in advanced and preventive testing-including cardiometabolic, autoimmune, brain health, oncology, and women's/reproductive diagnostics-as well as robust demand from functional medicine and wellness-focused consumers, are driving higher test volumes and increasing test-per-requisition, which supports both revenue growth and margin expansion.
  
• The accelerating shift toward preventive healthcare and wellness, visible in the expansion of functional medicine and consumer-initiated testing, is fueling sustained demand for recurring lab services; this trend underpins expectations for stable, long-term top-line growth and improved revenue durability.
  
• Increased adoption of automation, digitization, and artificial intelligence in laboratory operations is yielding productivity improvements and cost savings, contributing to margin expansion and enhancing future operating income and net earnings.
  
• Strategic execution on accretive acquisitions-including the large LifeLabs deal-and expanded health system partnerships (e.g., with Fresenius) are boosting patient volumes, expanding geographic reach, and producing procurement and operational synergies that are expected to materially lift revenue and earnings.
  
• The rising importance of health data analytics and Quest's role as a "lab engine" for consumer wellness brands positions the company to benefit from new revenue streams and further monetization opportunities as healthcare becomes more data-driven, supporting long-term earnings power.

Quest Diagnostics Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming Quest Diagnostics's revenue will grow by 4.1% annually over the next 3 years.
• Analysts assume that profit margins will increase from 9.0% today to 10.7% in 3 years time.
• Analysts expect earnings to reach $1.3 billion (and earnings per share of $10.93) by about September 2028, up from $945.0 million today. However, there is some disagreement amongst the analysts with the more bearish ones expecting earnings as low as $1.0 billion.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 20.2x on those 2028 earnings, down from 21.6x today. This future PE is lower than the current PE for the US Healthcare industry at 21.0x.
• Analysts expect the number of shares outstanding to grow by 0.19% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 6.78%, as per the Simply Wall St company report.

Quest Diagnostics Future Earnings Per Share Growth

Risks

• Potential reductions in reimbursement from PAMA (Protecting Access to Medicare Act), if not reformed or delayed, could result in approximately $100 million in annual pricing headwinds that would not be fully offset by internal actions, negatively impacting revenue and net margins.
  
• The recently passed "One Big Beautiful Bill" and resulting forecast for 10 million more uninsured Americans over the next decade may reduce overall healthcare coverage, posing risks to Quest's test volumes and revenue growth over time, especially if utilization rates among uninsured do not offset the loss.
  
• Increased exposure to government and exchange-based payers, as seen with LifeLabs acquisition and payer mix shift, heightens Quest's vulnerability to adverse changes in public healthcare policy, reimbursement schedules, and payment delays, potentially compressing net margins and earnings.
  
• Persistent industry price pressures from consolidation among healthcare providers and insurers, as well as competition from non-traditional entrants (such as retail clinics and consumer health tech companies), could erode Quest's pricing power and market share, impacting long-term revenue and profitability.
  
• Ongoing wage inflation (3–4% annually) and the need for heavy investments in modernization and automation (Project Nova, advanced technology deployment) may cause operating expenses to rise faster than anticipated, which, if not matched by sufficient productivity gains, could limit improvements in operating margins and earnings growth.

Valuation

• The analysts have a consensus price target of $188.188 for Quest Diagnostics based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $200.0, and the most bearish reporting a price target of just $166.0.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $11.9 billion, earnings will come to $1.3 billion, and it would be trading on a PE ratio of 20.2x, assuming you use a discount rate of 6.8%.
• Given the current share price of $182.68, the analyst price target of $188.19 is 2.9% higher. The relatively low difference between the current share price and the analyst consensus price target indicates that they believe on average, the company is fairly priced.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
