2019 Equity Incentive Plan financial

"All shares were acquired pursuant to an annual director award issued under the Alerus Financial Corporation 2019 Equity Incentive Plan."

"Includes 1,772 shares of restricted stock."

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

annual director award financial

"All shares were acquired pursuant to an annual director award issued under the Alerus Financial Corporation 2019 Equity Incentive Plan."
