8. EMPLOYEE BENEFIT PLANS

401(k) Plan

In November 1998, we established the IES Holdings, Inc. 401(k) Retirement Savings Plan. All full-time IES employees are eligible to participate on the first day of the month subsequent to completing sixty days of service and attaining age twenty one. Participants become vested in our matching contributions following three years of service. We also maintain several subsidiary retirement savings plans. During the three months ended March 31, 2022 and 2021, we recognized $1,195 and $773, respectively, in matching expense. During the six months ended March 31, 2022 and 2021, we recognized $2,116 and $1,479, respectively, in matching expense.
