The increase in price target by Piper Sandler indicates an expectation of Steris's stock price to rise, reflecting a positive sentiment towards the company's future performance. However, the Neutral rating suggests that there are still some reservations or uncertainties that prevent a more bullish stance. This could lead to a short-term positive impact on the stock as investors may view the raised target as a sign of confidence in the company's value, albeit with caution due to the neutral stance.
