restricted stock financial

"Shares of restricted stock vest at a rate of 33 1/3% per year"

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.

vest financial

"vest at a rate of 33 1/3% per year commencing on May 26, 2027"

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

What insider transaction did RBKB CFO Kevin M. Nihill report?

CFO Kevin M. Nihill reported receiving a grant of 9,632 shares of restricted Rhinebeck Bancorp common stock. The award was recorded at zero purchase price and is classified as a grant or award acquisition, rather than an open-market buy or sell transaction.

How many RBKB shares does the CFO own after this Form 4 transaction?

After the restricted stock grant, Kevin M. Nihill directly holds 25,164 Rhinebeck Bancorp common shares. This total includes both unrestricted and restricted stock positions, reflecting his updated equity stake following the May 26, 2026 compensation award.

The 9,632 newly granted restricted shares vest in three equal installments of 33 1/3% per year. Vesting begins on May 26, 2027, meaning the award becomes fully vested over a three-year period, aligning compensation with longer-term company performance.

Yes. The total reported holdings include earlier restricted stock that vests 33 1/3% per year. Vesting for that prior award begins on July 9, 2025, creating a staggered vesting schedule across multiple three-year restricted stock grants for the CFO.

No. The Form 4 classifies the transaction under code “A,” meaning a grant, award, or other acquisition. The 9,632 restricted shares were issued at a price of $0.0000 per share, so it is compensation-related, not an open-market buy or sell.
