Qualstar Corp. received a warning letter from Nasdaq for non-compliance because the company’s stockholder equity has fallen below the threshold.

The Simi Valley tape storage and power products manufacturer failed to maintain a minimum of $10 million in shareholder equity required for listing on the Nasdaq Global Market, according to the letter made public May 29. As of March 31, the company had shareholder equity of $9.8 million.

Qualstar’s next options include filing a plan to regain compliance or transfer to the Nasdaq Capital Market, which has less stringent requirements.

Shares closed up 8 cents, or 6 percent, to $1.34 in trading on the Nasdaq.


Carlyle Group will further reduce its stake in Wesco Aircraft Holdings Inc. with an offering of 6 million shares in the Valencia aerospace parts supplier, the companies announced Wednesday.

Affiliates of the Washington, D.C. private equity firm are offering 6 million shares at $20.50 a share. The firm also could sell an additional 900,000 shares in Wesco should the offering sell out.

If all 6.9 million shares sell, that would leave Carlyle with a 23.1 percent stake in Wesco. In August, Carlyle sold 6.9 million shares in Wesco priced at $18.87 per share.

Carlyle bought a majority stake in the company in 2006 when it was privately held, and took it public in July 2011, raising $315 million in the initial public offering.

Wesco shares fell $1.56, or 7 percent, to close at $19.98 on the New York Stock Exchange.
