Allegion plc's first-quarter revenue rose to $1.03 billion, a 9.7% year-on-year increase, indicating strong growth despite market pressures. However, Bank of America downgraded its stock price target from $157 to $150 while maintaining a Neutral rating, causing the stock to decline by 8.7% over the past month. This comes as the company grapples with weak demand in the residential security sector, overshadowing its positive revenue performance.
