Nuwellis Inc. shares fell about 17% in premarket trading after the company named Carisa Schultz as its new chief financial officer, effective February 2, 2026. The cardiorenal-focused medtech firm also disclosed an agreement to acquire Israeli kidney-monitoring company Rendiatech Ltd., announced Thursday evening.

Key Points

  • Nuwellis named Carisa Schultz as CFO effective February 2, 2026; stock fell about 17% in premarket trading.
  • Schultz’s background includes Vice President of Finance at NeueHealth, roles at Boston Scientific, and Big Four accounting experience; she led enterprise finance, treasury, and corporate development at NeueHealth.
  • Nuwellis announced an agreement to acquire Rendiatech Ltd., an Israeli medtech company focused on automated kidney function monitoring; the company develops precision fluid management technologies for patients with fluid overload.

Nuwellis Inc. (NASDAQ: NUWE) experienced a pronounced premarket decline of 17% following the company's disclosure that Carisa Schultz will assume the role of chief financial officer effective February 2, 2026.

The appointment was announced alongside executive commentary highlighting Schultz's experience with publicly traded companies and deep healthcare finance credentials. Nuwellis' chief executive emphasized the importance of that background for the company going forward. "Her expertise and disciplined approach will be instrumental as we continue to execute our strategy and advance our cardiorenal platform," the CEO said.

Schultz joins Nuwellis from NeueHealth, the healthcare company previously known as Bright Health Group, where she served as Vice President of Finance. Her resume also includes financial leadership roles at Boston Scientific and experience at one of the Big Four public accounting firms. During her tenure at NeueHealth, Schultz oversaw enterprise finance, treasury, and corporate development functions.

Commenting on her new position, Schultz said, "I’m excited to join Nuwellis at an important juncture in its growth. The company’s focus on precision cardiorenal care represents a meaningful opportunity, and I look forward to working with the leadership team to support long-term value creation."

Nuwellis develops precision fluid management technologies aimed at patients experiencing fluid overload. The company also announced a planned acquisition Thursday evening of Rendiatech Ltd., an Israeli medical technology business that focuses on automated monitoring of kidney function.

The sequence of announcements - a senior finance hire coupled with a strategic acquisition disclosure - coincided with the steep premarket price move. Market participants reacted ahead of the open, resulting in the notable intraday weakness in the stock's trading during premarket hours.


Key points

  • Nuwellis named Carisa Schultz as CFO, with the appointment effective February 2, 2026, a move that preceded a roughly 17% premarket drop in the company’s stock.

  • Nuwellis also disclosed it will acquire Rendiatech Ltd., an Israeli medtech firm focused on automated kidney function monitoring; the company develops precision fluid management tools for patients with fluid overload.

Risks and uncertainties

  • Share-price volatility following the leadership announcement illustrates investor uncertainty in the financial markets and the healthcare/medtech sector about management changes.
  • The integration and expected outcomes of the Rendiatech acquisition remain uncertain and could affect operational execution within Nuwellis’ medtech business.
  • Execution of the company’s strategy is explicitly tied to finance leadership, and the transition to a new CFO introduces implementation risk for planned corporate and financial initiatives.

Risks
