From a style perspective, value stocks outperformed growth, with the Russell 2000 Value Index rising ~4.5% and the Russell 2000 Growth Index falling almost 3%. The outperformance of the value is driven by weakness in speculative names aligning with the Fund’s style and preference for quality, profitable franchises.

Madison Small Cap Fund stated the following regarding ICU Medical, Inc. (NASDAQ:ICUI) in its Q1 2026 investor letter:

"ICU Medical, Inc. (NASDAQ:ICUI) is a medical device company that specializes in infusion therapy, vascular access, and vital care applications. The company’s main business is intravenous delivery devices, and it provides both systems and consumables associated with these pumps. The business is headquartered in San Clemente, California, and has been around for over 40 years.

ICUI’s model is a sticky consumables stream that follows its equipment sale and installation. The industry is consolidated among three players, with ICUI being the smallest. ICUI has gained market share in the pumps business due to quality issues at Becton Dickinson (BDX) and underinvestment at Baxter (BAX). Additionally, the company’s new high-volume pump has more connected features, which we believe will drive retention rates and incremental revenue. This is a boring company with a good market position and excellent cash flow that we view as well-positioned in this volatile market.

We value this opportunity at 12x earnings before interest, taxes, depreciation, and amortization (EBITDA), which blends our intrinsic value estimate to ~$200/share."
