Waters (WAT) is back in focus after Senior Vice President Robert L. Carpio III resigned from the Waters Analytical Sciences Division, and Tina Wu has stepped into the role following her recent senior leadership experience at DuPont.

Waters shares trade at US$410.70 after a 10.75% 1 month share price return and 19.96% 3 month share price return. The 1 year total shareholder return of 35.91% contrasts with a modest 0.82% total shareholder return over five years, suggesting momentum has picked up recently as investors reassess the company following leadership changes and other developments through 2026.

Waters has already moved sharply, yet some investors may still be waiting for a pullback. Is the recent strength after the leadership change stretching the valuation, or does the current price still look reasonable on fundamentals?

Most Popular Narrative: 60% Undervalued

The most followed narrative values Waters at $413.26 per share using an 8.13% discount rate, which sits slightly above the latest $410.70 close. That gap is small in dollar terms, yet the narrative still frames the stock as meaningfully undervalued based on its long term cash flow potential.

Recurring revenues are accelerating (up 11% this quarter), underpinned by expanding service plan attachments and e-commerce adoption, which enhances revenue stability and net margins, setting up the combined company for more resilient earnings across CapEx cycles.

Curious how Waters gets from today’s earnings to that higher valuation? The narrative leans on compound growth, thicker margins, and a future profit multiple usually linked with faster growing sectors. Investors may want to examine which specific revenue and earnings paths are implied.

Result: Fair Value of $413.26 (UNDERVALUED)

However, you still need to factor in risks for Waters, including potential challenges integrating BD’s Biosciences and Diagnostic Solutions units, as well as pressure from weaker academic and pharma discovery demand.

Another View on Waters Using Sales Multiples

The SWS DCF model points to upside for Waters, yet the sales multiple tells a different story. The stock trades on a P/S of 8.7x, compared with a fair ratio of 7.2x, the US Life Sciences average of 4.5x, and a 5.7x peer average. That richer multiple could mean investors are paying up, so how much margin of safety do you think is left?
