Medidata Solutions Inc., a maker of software and services for clinical development of drugs and medical devices, said Friday it plans a public offering of 4.5 million shares of its common stock.
Shares of the New York-based company fell $1.06, or about 6 percent, to $16.72 in morning trading. Medidata makes software and provides services to help pharmaceutical, biotechnology and medical device companies run clinical trials.
The offering, announced about five months after Medidata's initial public offering, would dilute the value of the company's existing shares. A regulatory filing listed nearly 22.7 million shares outstanding as of Nov. 9.
Medidata, which filed a registration statement with the Securities and Exchange Commission, said the shares are being offered by certain stockholders of the company. Those include funds affiliated with Insight Venture Partners. Medidata will not receive any proceeds from the offering, the company said.
