Ensign Group Inc., a Mission Viejo-based nursing home and rehabilitative care company, is set to go public this week.

The company is looking to raise about $70 million after fees. Ensign plans to offer 4 million shares at $18 to $20.

In October, Ensign cut its expected price range from $20 to $22.

Other shareholders plan to offer 600,000 shares, estimated at about $10 million.

The total offering is set to come in at about $92 million.

Ensign could see a market value of about $400 million, according to Renaissance Capital LLC's IPOHome.com

For the six months through June, Ensign posted a profit of $9.8 million, a 9% drop from a year earlier. Sales for the period grew 17% to $198.2 million versus a year ago.

The company plans to use the proceeds of its offering to buy additional facilities, upgrade existing ones, pay down debt and for general purposes.

It was founded in 1999 and has 61 facilities in California and five other states. The company has 5,506 workers.

The stock is set to trade on Nasdaq under the ticker “ENSG.” Great Falls, Montana-based D.A. Davidson & Co. and Stifel Nicolaus & Co. of St. Louis are underwriting the offering.
