HTG Molecular Diagnostics announced recently after the close of the market that it intends to offer an undisclosed amount of its common stock in a public offering. 

The Tucson, Arizona-based diagnostics firm did not price its offering. 

Cantor Fitzgerald is the sole book-running manager for the offering. HTG expects to grant the underwriter a 30-day option to purchase additional shares of its common stock at the public offering price. 

The company had $11.8 million in cash and cash equivalents and $9.8 million in short-term investments as of June 30, it said during its second quarter earnings announcements last month.
