Ameriprise Financial Inc. (AMP) plans to offer $900 million in common stock, saying it will use the proceeds for general corporate purposes, including possible future acquisitions.

Shares fell 5.6% to $26.80 in after-hours trading, before being made unavailable for trading.

The provider of financial planning services, which has a market capitalization of about $6.25 billion, said the funds could be used to support growth initiatives and take advantage of any acquisition opportunities as they come available.

Last month, the company said it was looking at merger-and-acquisition opportunities, which it said are coming about more and more in the market. Two areas the brokerage said it might look to augment are its retail-distribution and asset-management capabilities. Last November, Ameriprise acquired H&R Block Financial Advisors.

Companies across a host of industries are looking to take advantage of increased investor interest in stock offerings amid the three-month stock rally.

The deal's underwriters have the option to buy an additional 15% in stock to cover overallotments. The company had 223.5 million shares outstanding as of March 31.

J.P. Morgan Securities Inc. and Merrill Lynch & Co. will serve as joint book-running managers for the offering.
