Why RenTech Added McKesson (MCK) in Q2 2025 — With Macro and Financial Realities


What Exactly Does McKesson Do?

McKesson (NYSE: MCK) is one of the largest healthcare distributors in the world. It doesn’t invent miracle drugs — it just makes sure those drugs actually reach pharmacies, hospitals, and clinics. Think of it as the plumbing of the healthcare system: invisible until it breaks, but absolutely essential.

McKesson has also been leaning heavily into specialty and biopharma distribution (like cancer drugs and biologics), plus tech and supply-chain services that link manufacturers, payors, and providers together.


How McKesson Has Been Performing Lately

  • In fiscal 2025, McKesson booked quarterly revenue above $90 billion, growing roughly +19–21% year over year.

  • Adjusted EPS has been consistently surprising to the upside, with double-digit percentage growth.

  • Full-year guidance for fiscal 2026 was raised into the low-$30s per share range.

  • McKesson also announced a plan to spin off its Medical-Surgical Solutions unit to sharpen focus on higher-margin areas like oncology and specialty drugs.

  • Despite the growth, McKesson’s operating margins remain razor thin at about 1–1.2%, and net profit margins under 1%. Scale, not fat margins, is the engine here.

  • The company has been actively returning capital via stock buybacks — billions of dollars in share repurchases in fiscal 2025 alone.


Why RenTech Might’ve Pushed a New Bet in MCK

1. Defensive Strength in a Slowing Economy

The U.S. economy in 2025 is wobbling between soft landing and mild recession. Profits in manufacturing, retail, and transport have been collapsing. But people don’t stop filling prescriptions. That makes McKesson a rare pocket of stability.

2. Specialty & Biopharma = Growth Path

Specialty distribution and oncology drugs are higher-margin segments than bulk generics. McKesson is reorganizing and investing aggressively here, positioning itself for stronger long-term profitability.

3. Quant Signals in Valuation & Momentum

McKesson trades at lower multiples than most high-growth sectors. At the same time, healthcare as a sector has been showing relative momentum. RenTech’s models may have flagged this as a “value + defensive growth” play.

4. Portfolio Diversification

For a quant book filled with volatility-prone names, McKesson offers ballast. Its cash flows smooth out overall portfolio risk.

5. Strategic Moves That Unlock Value

The spin-off of lower-margin businesses and focus on specialty growth could re-rate the stock higher. Coupled with buybacks, McKesson is quietly shareholder-friendly.


Risks to Watch

  • Policy and regulation: U.S. drug pricing reform remains a constant overhang.

  • Execution risk: Specialty distribution requires capital, integration, and precision.

  • Thin margins: Even small cost shocks in labor, transportation, or compliance can dent earnings.

  • Competition: Cardinal Health, Cencora, and even tech players like Amazon lurk in the background.


My Take

RenTech didn’t buy McKesson because it’s flashy. They bought it because it’s boring in the best way.

In 2025, when profits across nonfinancial industries are plunging, McKesson represents the kind of durable, predictable revenue stream that quant systems crave. Add in the demographic tailwinds of an aging population, rising specialty drug demand, and corporate restructuring, and it’s a low-drama way to play healthcare growth.


Bottom Line: In Q2 2025, Renaissance Technologies started a new position in McKesson because it offers stability in a shaky macro environment, growth in specialty healthcare, and undervalued cash flows. It’s not a rocket ship — but it’s the kind of steady engine RenTech likes to keep humming in the background.
