Roche (SWX:ROG) Valuation After FDA Expansion of PATHWAY and VENTANA HER2 Diagnostic Test Uses

Roche Holding (SWX:ROG) just picked up an FDA win for expanded use of its PATHWAY anti HER2 and VENTANA HER2 tests, widening the pool of metastatic breast cancer patients eligible for ENHERTU based on more granular HER2 profiling.

That FDA nod slots into a busy few weeks for Roche, with new oncology and diagnostics data out of major conferences and fresh European approvals helping underpin a roughly 24.6% 3 month share price return and 29.8% 1 year total shareholder return, suggesting positive momentum is building.

Yet with shares already near analyst targets but still trading at a steep discount to some intrinsic value estimates, investors now have to ask: is Roche a buy on underappreciated growth, or has the market caught up?

Most Popular Narrative: 3.2% Overvalued

With Roche shares closing near CHF 321.90 against a narrative fair value around CHF 312, the story hinges on how far future earnings can stretch this gap.

In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 17.0x on those 2028 earnings, down from 24.3x today. This future PE is lower than the current PE for the GB Pharmaceuticals industry at 30.9x.

Read the complete narrative.

Curious how modest growth, rising margins, and a lower future earnings multiple still add up to a richer valuation than today? The narrative connects these moving pieces in a way that might surprise you, but the real twist is how much faith it puts in Roche’s long term earnings power and competitive moat. Want to see the full logic behind that stance before you decide where you stand?

Result: Fair Value of $312 (OVERVALUED)

However, meaningful biosimilar erosion after 2026 and ongoing China pricing pressure could quickly undermine those optimistic earnings assumptions and compress Roche’s valuation.

Another View: Market Ratio Says Cheap, Not Rich

While the narrative fair value suggests Roche is about 3.2% overvalued, our earnings based valuation tells a different story. At roughly 29 times earnings versus a fair ratio of 36.7 times and peers at 81.2 times, the shares screen as materially cheaper than both fair value and competitors. Is the market underestimating Roche’s staying power, or simply pricing in more risk than the models suggest?
