Zimmer Biomet (NYSE:ZBH) said late yesterday its prez and CEO David Dvorak has resigned from his position at the head of the company, effective immediately, to be replaced on an interim basis by senior VP and CFO Daniel Florin until a permanent successor is named.

The Warsaw, Ind.-based company said it is retaining “a leading executive search firm” as it pursues a new candidate to permanently fill the CEO role.

“Serving alongside Zimmer Biomet’s dedicated employees over the past 16 years and leading the company as CEO for ten of those years has been a privilege and a highlight of my professional career. Our collective efforts grew employment from approximately 3,000 in 2001 to 18,000 today and built a Fortune 500 company. I am particularly proud of what we have accomplished working together with surgeons and clinicians to help millions of patients globally improve their quality of life,” Dvorak said in a press release.

“During David’s 10-year tenure as CEO, Zimmer Biomet has transformed into a truly global leader in musculoskeletal healthcare. Through a combination of organic growth and strategic acquisitions, Zimmer Biomet’s revenue has doubled and the company has established a leading portfolio of technologies, solutions and personalized services. With this strong platform in place, there is tremendous opportunity for Zimmer Biomet. On behalf of the board, I thank David for his many important contributions to our company and industry over the years and wish him much success in the future. We are fortunate to have a leader of Dan’s caliber and experience to step into the CEO role on an interim basis while the board conducts its search process. Dan’s knowledge of Zimmer Biomet and his achievements here and at other medical device companies make him an excellent choice to support the company through this interim period. We appreciate his willingness to take on this expanded role,” board chair Larry Glasscock said in a prepared statement.

The move has elicited positive responses from industry analysts today. RBC Capital Market’s Glen Novarro said that the company has been “in need of new direction and better leadership for some time,” according to a RyOrtho report.

Leerink Partners analyst Richard Newitter saw the change as an inevitable one for the company, saying that the company’s “poor execution (i.e. supply issues, continued guidance re-sets) can only go on for so long before prompting a leadership change and ultimately renewing promise of improved execution & increased value creation potential for shareholders into the future,” according to the report.

A change in leadership could signal a shift for the company, which could use a turnaround according to Wells Fargo analyst Larry Biegelsen. Biegelsen said the company’s weak 2nd quarter results indicated the company’s supply issues “persist and recapturing sales lost to competitors over the last several quarters may not return as quickly as expected,” RyOrtho reported.

“We believe that investors would like to see an experienced CEO with a strong track record. We believe that the new CEO choice is critical to restore investor confidence in the company,” Biegelsen said, according to the report, noting that potential candidates could include former Biomet CEO Jeff Binder, former  Stryker (NYSE:SYK) CEO Steve McMillan and ZBH board member Gail Boudreaux.

In the meantime, the position will be filled by Florin, who took his position as Senior VP and CFO in June 2015, and has 16 years in the medical device industry, Zimmer Biomet said.

Florin operated as senior VP and CFO of Biomet from June 2007 to June 2015, and operated as VP and corp controller at Boston Scientific (NYSE:BSX) from 2001 to 2007, and has also held positions at C.R. Bard (NYSE:BCR) and Deloitte.

“Zimmer Biomet has a talented and dedicated team and an unmatched portfolio. I am honored to assume the Interim CEO role and I look forward to working closely with the board, senior leadership team and our sales force as we strive to support our customers and enhance stockholder value,” Florin said in a prepared release.
