IntriCon Corporation provided revenue guidance for the second quarter and full year of 2021. The company expects second quarter 2021 revenue to slightly lag first quarter results due to COVID-19 related pent up demand recognized in the first quarter of 2021 and present challenges regarding staffing and input supply constraints. The company expects full year 2021 revenue to range between $119 million and $123 million, representing year-over-year growth of 16-20%.
