NEW YORK (TheStreet) -- Shares of Fairmount Santrol (FMSA) are rising 7.64% to $6.62 on heavy trading volume Thursday morning after the company announced a 25 million share offering and was upgraded at Piper Jaffray.
After yesterday's market close, the Chesterland, OH-based company announced the pricing of its underwritten public offering of 25 million shares of common stock for total gross proceeds of about $148.75 million.
Piper Jaffray raised its rating on shares to "overweight" from "neutral" and maintained its $8 price target, the Fly reports.
The firm cited the 25 million share offering as the reason for the upgrade, which it views as a deleveraging event.
Piper Jaffray also has a positive outlook on the frac sand market.
Last week, the stock tumbled after releasing preliminary results for the 2016 second quarter.
Fairmount Santrol is a provider of high-performance sand and sand-based products used by oil and gas exploration and production companies to boost productivity of their wells.
