Renaissance Investment Management, an investment management company, released its Q4 2024 investor letter. Here is what the fund said:

“TransMedics Group, Inc. (NASDAQ:TMDX) detracted the most from performance in the quarter as the organ trans plant solutions company reported third-quarter results that were modestly below expectations. However, the company’s proprietary organ preservation system coupled with its logistics solutions should allow significant opportunities for market-share gain for a number of years, and we believe that long-term growth opportunities remain intact.

Trading and stock movements during the quarter led to several changes in portfolio sector weights. The Information Technology, Health Care, Financials, and Consumer Staples sector weights increased during the quarter, while the Industrials, Consumer Discretionary, Energy, and Communication Services sector weights decreased.”
