Waters (WAT) Surges 3% on Buy Rating and Earnings Beat: Is This the Catalyst for a New Bull Run?

Summary
• Waters (WAT) rockets 3.2% to $328.79 after Rothschild & Co initiates coverage with a $390 price target
• Q2 2025 earnings smash guidance, with $771M revenue and 8% constant currency growth
• Sector peers like Agilent (A) rally 2.37%, signaling analytical instruments' resilience

Waters Corporation (WAT) is surging on a perfect storm of analyst optimism and earnings outperformance. The stock’s 3.2% intraday jump to $328.79 follows a high-conviction 'Buy' rating from Rothschild & Co and a Q2 earnings report that exceeded expectations. With the analytical instruments sector showing strength and Waters raising 2025 guidance, investors are recalibrating their risk-on stance. This move could mark a pivotal inflection point for a stock trading 21% below its 52-week high.

Rothschild's Buy Rating and Earnings Outperformance Ignite Momentum
Waters’ 3.2% surge stems from two catalysts: Rothschild & Co’s initiation of coverage with a $390 price target and a Q2 earnings report that outperformed guidance. The firm highlighted Waters’ acquisition of BD’s Biosciences, which doubled its addressable market to $40B, as a value-adding move with strong EPS growth potential. Meanwhile, Q2 results showed $771M in revenue (up 9% YoY), driven by 11% recurring revenue growth and 8% constant currency sales. These results, coupled with raised 2025 guidance, have rekindled investor confidence in Waters’ ability to navigate macroeconomic headwinds.

Analytical Instruments Sector Gains Momentum as Agilent (A) Rallies
The analytical instruments sector is showing resilience, with Agilent Technologies (A) rising 2.37% alongside Waters. Agilent’s Q2 revenue of $1.67B (up 6% YoY) and Waters’ $771M print highlight strong demand for lab equipment in pharma and environmental testing. This sector strength is driven by labs investing in high-throughput analysis tools and regulatory-compliant workflows, even amid economic uncertainties. Waters’ 3.2% move aligns with the sector’s broader trend of capitalizing on pharmaceutical R&D and PFAS testing demand.
