A single-quarter beat paired with an upward revision to the full-year earnings range is a high-signal catalyst for investors in diagnostics and lab services, since valuation typically anchors to forward EPS and confidence in demand/margins. The combination of double-digit adjusted EPS growth in the quarter and a higher 2026 earnings outlook is driving aggressive buying interest in the stock today. citeturn4view2citeturn4view4
