European Pharma’s Heavy Reliance on US Market

European pharma giants rake in massive sales from the US, but with Trump's aggressive push to slash drug prices and onshore production, how vulnerable are they really? Some companies get over 80% of revenue from American patients—could this spell trouble ahead?

Have you ever wondered why prescription drugs cost so much more in the United States than pretty much anywhere else in the world? It’s a question that’s been buzzing around for years, but lately, with the political winds shifting, it’s hitting closer to home for some of the biggest players in the pharmaceutical industry—especially those based in Europe.

The US isn’t just a market for these companies; it’s often the market. Higher prices there have long subsidized research and development globally, but now, with aggressive policies aimed at bringing those costs down, European pharma giants are facing some tough questions about their vulnerability.

The Overwhelming Pull of the American Market

Let’s cut to the chase: for many European pharmaceutical powerhouses, the United States represents a massive chunk of their revenue. It’s not uncommon to see figures north of 50% for some firms, and in a few cases, it’s pushing even higher. This isn’t by accident—American consumers have historically paid premiums that are often double or triple what patients shell out in Europe or other developed nations.

In my view, this reliance has been a double-edged sword. On one hand, it fuels innovation and blockbuster profits. On the other, it leaves these companies exposed to whatever policy changes come out of Washington. And right now, those changes are coming fast.

Breaking Down the Exposure Numbers

Among the top-tier European biopharma companies, the dependence varies quite a bit, but the trend is clear. Several heavyweights derive the majority of their sales from US patients. For instance, one Belgian specialist in rare diseases pulls in a staggering 85% from America. That’s not just significant—it’s dominant.

Others aren’t far behind. A British giant focused on vaccines and respiratory treatments gets well over half its revenue stateside, while a Danish leader in diabetes and obesity drugs isn’t much different. Even Swiss behemoths with broad portfolios, including diagnostics, lean heavily on US sales.

Then there are the more balanced players. Some German conglomerates, with diversified operations spanning chemicals and crop science, hover around 30%. A UK-based oncology and cardiology specialist sits at about 42%, but interestingly, they’re actively working to increase that share as part of ambitious growth targets.

  • Highest exposure: Around 85% for niche rare disease focused firms
  • Majority reliance: Common for pure-play pharma companies (50-70% range)
  • Lower end: Diversified giants closer to 30-40%
  • Growth ambition: Some aiming to boost US share for future revenue goals

These numbers aren’t static, either. Many of these firms have been pouring investments into US operations—building facilities, expanding teams—all in an effort to solidify their foothold.

Why the US Prices Have Been a Goldmine

It’s worth pausing here to think about why this imbalance exists in the first place. In the US, branded medications command premium pricing because of a complex system involving insurers, pharmacy benefit managers, and relatively limited government intervention—until recently, that is.

Contrast that with Europe, where national health systems negotiate hard or impose price controls. The result? The same drug can cost dramatically less across the Atlantic. For years, this has allowed pharma companies to recoup R&D costs primarily from American buyers, effectively subsidizing lower prices elsewhere.

But is that sustainable? I’ve always thought it creates a fragile equilibrium. When one side of the equation shifts—as it clearly is now—the whole structure wobbles.

The higher prices in the US have been crucial for funding innovation that benefits patients worldwide.

Policy Pressure: The Drive for Lower Prices

Enter the current administration’s aggressive stance on drug pricing. Initiatives like aligning US prices with the lowest paid in other wealthy nations—often called Most Favored Nation pricing—could reshape the landscape overnight.

Add to that direct negotiations, executive orders, and even threats of hefty tariffs for companies not investing sufficiently in domestic manufacturing. It’s a multi-pronged approach that’s putting real pressure on both American and European firms to the table.

We’ve already seen deals struck. Major players in weight-loss medications, cancer treatments, and more have agreed to reductions, often in exchange for other concessions. Analysts suggest some of these arrangements might not hit bottom lines as hard as feared, thanks to clever structuring.

Still, the message is unmistakable: change is here, and companies with heavy US exposure need to adapt quickly.

Onshoring and Investment Incentives

Another layer to this story is the push for bringing production back to American soil. Pharma has historically been globalized, with manufacturing spread across Europe, Asia, and beyond for cost efficiencies.

Now, with incentives and penalties dangling, many European firms are announcing big US investments—new plants, research hubs, job creation. It’s partly defensive, partly opportunistic. After all, being seen as a good corporate citizen in your largest market never hurts.

Perhaps the most interesting aspect is how this could shift long-term strategies. Companies might diversify revenue streams, bolster emerging markets, or innovate pricing models. But for now, the focus remains on navigating the immediate challenges.

Company TypeApprox. US Sales %Key Vulnerabilities
Niche Biotech80-85%High concentration risk
Specialized Pharma50-70%Blockbuster dependence
Diversified Giant30-50%Broader buffer but still exposed
Ambitious Grower40-45%Planned increase adds future risk

This table gives a simplified view, but it highlights the spectrum. No one is immune, but some are certainly more insulated than others.

Potential Ripple Effects Across the Industry

Lower US prices wouldn’t just affect balance sheets. Reduced profitability could slow R&D spending, delaying new therapies. Some experts worry that innovation incentives might diminish if the reward structure changes too drastically.

On the flip side, more affordable drugs could expand access in the US, boosting volume sales for certain products. It’s a classic trade-off: margins versus market share.

European companies, in particular, might face tough choices. Do they accept lower returns in their biggest market, or do they pivot elsewhere? Emerging markets like China and India are growing fast, but they come with their own regulatory hurdles and pricing pressures.

Looking Ahead: Adaptation Strategies

Smart firms are already moving. Beyond deals and investments, there’s talk of portfolio optimization—focusing on high-value therapies less susceptible to pricing caps, or advancing gene and cell therapies with fewer direct comparators.

Cost control is another lever. Streamlining operations, leveraging AI in drug discovery, partnering more aggressively—these could help offset revenue hits.

  1. Negotiate favorable terms in pricing agreements
  2. Accelerate US manufacturing investments
  3. Diversify geographic revenue sources over time
  4. Innovate in premium, hard-to-genericize therapies
  5. Enhance operational efficiency across the board

It’s early days, but the companies that adapt quickest will likely come out stronger. In my experience following these markets, resilience often comes from foresight rather than reaction.

One thing feels certain: the era of unchecked high pricing in the US is evolving. For European pharma, deeply intertwined with that system, the coming years promise both challenges and opportunities to reinvent.

Whether this leads to a healthier, more sustainable global pharma ecosystem or unintended consequences remains to be seen. But one way or another, it’s a story worth watching closely.
