Heartland Value Fund stated the following regarding Integer Holdings Corporation (NYSE:ITGR) in its fourth quarter 2025 investor letter:

"An example of a Health Care holding that struggled in the quarter was Integer Holdings Corporation (NYSE:ITGR), which specializes in the design, development, and production of medical technologies and components. In late October, Integer’s stock sank more than 30% after the company significantly lowered its outlook for growth and margin expansion in 2026, as several products experienced slower market adoption than was expected. But management expects these headwinds to be short-lived, with a robust portfolio of higher growth and margin products coming to market, which should allow the company to get back on track. The company still expects to outgrow its industry peers by 2% while growing earnings before interest and taxes (EBIT) at twice the rate of sales.

Even better, the company announced a $200 million stock repurchase authorization after the selloff, increasing our conviction that the shares are materially undervalued. This confidence drove us to increase our exposure to Integer in the quarter."
