Why did BMRC's Q2 2024 earnings fall short of forecasts?

Bank of Marin Bancorp's (BMRC) Q2 2024 earnings fell short of forecasts due to a combination of factors:

1. **Decrease in Revenue**: The bank experienced a notable decline in revenue, which is a critical indicator of its financial performance. This decrease was likely a significant contributor to the shortfall in earnings compared to forecasts.
2. **Net Interest Margin Pressure**: The bank faced pressure on its net interest margin, which is the difference between the interest income earned on loans and investments and the interest expense paid on deposits and borrowings. A narrowing net interest margin can lead to reduced profitability.

These factors, among others, likely combined to impact BMRC's earnings for the period, resulting in a shortfall relative to market expectations.
