NYSE:DGX Earnings & Revenue History as at Oct 2025

Margins Edge Up, but Below Industry Pace

  • Net profit margins stand at 9%, only a slight increase from 8.9% last year. Analysts expect further expansion to 10.7% over three years.
  • According to the analysts' consensus view, automation, AI adoption, and operational synergies are expected to accelerate margin growth. However, these improvements may not fully offset lower projected revenue growth compared to the broader US healthcare sector.
    • Consensus narrative notes that productivity gains from technology and acquisitions should drive stronger operating income, even as growth lags peers.
    • Cautious optimism persists since ongoing margin expansion is underpinned by digital and cost-saving initiatives rather than purely organic top-line increases.
  • The current share price of $184.64 is closely aligned with the analyst price target of 193.44, emphasizing that the market is already pricing in modest margin gains and slower revenue growth.
    • Despite positive efficiency moves, analysts believe Quest is fairly valued. The difference between the share price and price target is just 4.8%.
    • This muted premium suggests investors may be weighing upside from margin improvements against the modest pace of projected revenue growth.

Revenue Growth Trailing Market Averages

  • Quest Diagnostics is expected to grow revenue by 3.4% per year, notably below the broader US market and analyst consensus projections of 4.1% per year over the next three years.
  • Analysts' consensus view flags that, while growth in advanced diagnostics and consumer-driven wellness demand is boosting test volumes, the pace is still not enough to see Quest outpace peers or the industry average.
    • Competitive threats and a shifting payer mix threaten to weigh on top-line gains, even as acquisitions and scale help steady revenues.
    • The consensus expects recurring demand from preventive and wellness testing to support stability, but not to drive market-beating growth.

Trading at a Premium Despite DCF Discount

  • While Quest Diagnostics is trading below its DCF fair value ($184.64 vs. $322.37), the company's price-to-earnings ratio of 21.8x sits above both the US healthcare industry average (21.7x) and its peer group (20.1x).
  • Analysts' consensus view highlights the valuation tradeoff: Quest offers strong earnings quality and improving profitability but commands a higher price than sector rivals, likely due to perceived stability and dividend appeal.
    • Despite its below-average revenue growth, the company's financial strength and quality are enough to keep the stock valued above its direct competitors.
    • However, the premium may deter investors looking for faster growth or a deeper value discount relative to fair value estimates.
