NEOG vs TMO vs DHR vs BIO vs IQV

For growth investors, IQVIA Holdings Inc.

(IQV) is the stronger pick with 5. 9% revenue growth year-over-year, versus -3. 2% for Neogen Corporation (NEOG). Bio-Rad Laboratories, Inc. (BIO) offers the better valuation at 9. 2x trailing P/E (25. 0x forward), making it the more compelling value choice. Analysts rate Thermo Fisher Scientific Inc. (TMO) a "Buy" — based on 42 analyst ratings — the highest consensus in this comparison. The "better buy" depends entirely on your goals: growth investors should weight revenue trajectory, value investors should weight P/E and PEG, and income investors should weight dividend yield and streak.

On trailing P/E, Bio-Rad Laboratories, Inc.

(BIO) is the cheapest at 9. 2x versus Danaher Corporation at 34. 9x. On forward P/E, IQVIA Holdings Inc. is actually cheaper at 14. 1x — notably different from the trailing picture, reflecting expected earnings growth. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: IQVIA Holdings Inc. wins at 0. 35x versus Danaher Corporation's 34. 35x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.

Over the past 5 years, Thermo Fisher Scientific Inc.

(TMO) delivered a total return of +2. 8%, compared to -80. 6% for Neogen Corporation (NEOG). Over 10 years, the gap is even starker: TMO returned +229. 1% versus NEOG's -49. 8%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

By beta (market sensitivity over 5 years), Bio-Rad Laboratories, Inc.

(BIO) is the lower-risk stock at 0. 92β versus Neogen Corporation's 1. 83β — meaning NEOG is approximately 98% more volatile than BIO relative to the S&P 500. On balance sheet safety, Bio-Rad Laboratories, Inc. (BIO) carries a lower debt/equity ratio of 21% versus 2% for IQVIA Holdings Inc. — giving it more financial flexibility in a downturn.

By revenue growth (latest reported year), IQVIA Holdings Inc.

(IQV) is pulling ahead at 5. 9% versus -3. 2% for Neogen Corporation (NEOG). On earnings-per-share growth, the picture is similar: Bio-Rad Laboratories, Inc. grew EPS 142. 6% year-over-year, compared to -114. 6% for Neogen Corporation. Over a 3-year CAGR, NEOG leads at 19. 3% annualised revenue growth. Higher growth typically commands a higher valuation multiple — check whether the premium P/E or P/S is justified by the growth rate using the PEG ratio.

Bio-Rad Laboratories, Inc.

(BIO) is the more profitable company, earning 29. 4% net margin versus -122. 1% for Neogen Corporation — meaning it keeps 29. 4% of every revenue dollar as bottom-line profit. Operating margin tells a similar story: DHR leads at 20. 9% versus 1. 1% for NEOG. At the gross margin level — before operating expenses — DHR leads at 60. 9%, reflecting greater pricing power or product mix advantage. Stronger margins indicate durable pricing power, lower cost of revenue, or higher mix of software/services. They are one of the clearest signs of business quality.

The PEG ratio (forward P/E divided by expected earnings growth rate) is the most precise measure of undervaluation relative to growth potential.

By this metric, IQVIA Holdings Inc. (IQV) is the more undervalued stock at a PEG of 0. 35x versus Danaher Corporation's 34. 35x. A PEG below 1. 0 is traditionally considered the threshold for growth-adjusted undervaluation. On forward earnings alone, IQVIA Holdings Inc. (IQV) trades at 14. 1x forward P/E versus 25. 9x for Neogen Corporation — 11. 8x cheaper on a one-year earnings basis. Analyst consensus price targets imply the most upside for DHR: 40. 6% to $247. 00.

In this comparison, DHR (0.

7% yield), TMO (0. 4% yield) pay a dividend. NEOG, BIO, IQV do not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Danaher Corporation (DHR) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0.

94), 0. 7% yield, +219. 3% 10Y return). Neogen Corporation (NEOG) carries a higher beta of 1. 83 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (DHR: +219. 3%, NEOG: -49. 8%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

Both stocks operate in the Healthcare sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: NEOG is a small-cap quality compounder stock; TMO is a mid-cap quality compounder stock; DHR is a mid-cap quality compounder stock; BIO is a small-cap deep-value stock; IQV is a mid-cap quality compounder stock. DHR pays a dividend while NEOG, TMO, BIO, IQV do not, making them suitable for different income and tax situations. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
