There were contrasting fortunes for the two Houston-based companies that were pricing their Initial Public Offerings this week.

Sunnova Energy International, a residential solar energy provider, priced its IPO at $12 per share.  That’s below the expected range of between $16 and $18 per share. However the company is selling the same number of shares (17.6 million). At that price, the company will raise $221 million and have a market value of $1.1 billion.  The shares will begin trading on the NYSE on July 25 under the symbol NOVA.

Castle Biosciences, based in Friendswood, priced its IPO at $16 per share. That’s at the top end of the expected range of $14 to $16 per share. Also the company also increased the number of shares on offer from 3.3 million to 4.0 million. The gross proceeds are expected to be $64 million. The shares will also begin trading on July 25, but on the Nasdaq under the symbol CSTL.

The company is a commercial-stage dermatological company that uses genomes to provide physicians and their patients with more accurate treatment decisions. The main product is a multi-gene expression profile test that predicts the risk of metastasis or recurrence for patients diagnosed with invasive cutaneous melanoma, a deadly skin cancer.

I’ve added the two companies to the list of Houston-area public companies which you can see here. However I have deleted American Midstream from the list, whose deal to go private was completed yesterday.
