Shares of Hanmi Financial Corp. jumped Thursday after the Koreatown bank holding company canceled a $75 million secondary offering, saying its shares were undervalued.

The parent of Hanmi Bank said the offering was fully subscribed and there was excess demand for its stock, but the board was unsatisfied with the pricing, the company said in a statement. It did not disclose what price it wanted.

“Recent market volatility, particularly as it affects financial stocks, has created an environment in which many stocks are undervalued, including, we believe, our company’s shares,” Chief Executive Jay Yoo said in a statement. “Because we currently have a strong capital position, we have decided to wait for an improved market environment.”

As a result of the cancellation, South Korea’s Woori Investment & Securities will not be able to acquire a 4.9 percent stake in Hanmi, which was to be part of the $75 million offering. Woori would still be able to buy existing shares on the open market, or potentially negotiate a private placement down the road, bank officials said.

Hanmi on June 15 terminated an agreement that would have enabled Woori to take a majority stake. Woori had agreed to purchase up to $240 million of Hanmi’s stock, but the deal was abandoned amid regulatory hurdles. The two banks now plan a business alliance that would provide their customers with improved international services.

Following real estate loan losses during the recession, the bank last June raised more than $120 million from existing and new shareholders in two private placements that enabled it to return to “well capitalized” status.

Shares closed up 16 cents, or nearly 18 percent, to $1.07 on the Nasdaq, which market observers attributed mainly to investors covering their short positions on the stock. After the offering was announced June 20, the company’s share price fell more than 16 percent and had only recovered slightly before today’s announcement.
