TD employee ownership program

My wife currently works at TD Bank and they their EOP program matches the first $250 worth of stock at 100% and the next $2000 at 50%. To a maximum of $2250 a year. So we would have to contribute $4250 from her salary to get the full benefit. We are currently exceeding that amount and I was wondering if that was a good idea or should we just stop once we’ve hit the total amount they’d match?

Thank you!
