Baron Discovery Fund stated the following regarding Establishment Labs Holdings Inc. (NASDAQ:ESTA) in its fourth quarter 2025 investor letter:
"Shares of Establishment Labs Holdings Inc. (NASDAQ:ESTA) contributed to performance. Establishment Labs sells next-generation Motiva breast implants that have meaningfully lower safety risks and aesthetic benefits compared to competitors. In particular, Motiva implants cause significantly less capsular contracture (where surrounding tissue squeezes the implant) and no known cancer risks. Motiva also comes in a more natural Ergonomix shape with a natural-feeling softer fill as well as potentially a smaller implant scar. The company's implants have captured significant share in many international markets, and the U.S. launch is now underway and progressing well, having already captured about 20% of U.S. aesthetic breast augmentation market. Reconstruction approval (for cancer survivors) should occur in 2026 as well. We believe Establishment will capture substantial plurality share in the U.S. over the next few years, which will drive significant revenue growth, profitability (it will be free cash flow positive in 2026), and value creation."
