AltaGas Ltd. ("AltaGas") (TSX:ALA) announced today that it has entered into an agreement with a syndicate of underwriters co-led by TD Securities Inc., BMO Capital Markets and RBC Capital Markets to issue 7.850 million common shares (the "Common Shares") on a bought deal basis at an issue price of $51.00 per Common Share (the "Offering Price") for total gross proceeds of approximately $400 million (the "Offering"). The net proceeds resulting from the Offering will be used to partially fund AltaGas' capital growth program, reduce bank indebtedness and for general corporate purposes.

AltaGas continues to make significant progress on its growth opportunities. Earlier today, AltaGas announced a 15-year strategic alliance with Painted Pony Petroleum Ltd. ("Painted Pony") and the construction of Townsend, a new 198 Mmcf/d shallow-cut gas processing facility in the Montney resource play. The strategic alliance is expected to further expand AltaGas' fully integrated midstream business, while providing essential gas processing infrastructure for Painted Pony's world class Montney reserves. AltaGas also continues to advance its other growth opportunities including the potential expansion of Blythe and its energy export initiatives.

AltaGas has granted the underwriters an over-allotment option to purchase, in whole or part, up to an additional 1,177,500 Common Shares at the Offering Price to cover over-allotments, if any, for a period of 30 days following the closing of the Offering. If the over-allotment option is exercised in full, gross proceeds from the Offering will be approximately $460 million.

The Common Shares will be offered in all provinces of Canada by way of a supplement under the Corporation's base shelf prospectus dated August 23, 2013. The Offering is subject to the receipt of all necessary regulatory and stock exchange approvals. Closing of the Offering is anticipated to occur on or about August 28, 2014.

This news release does not constitute an offer to sell securities, nor is it a solicitation of an offer to buy securities, in any jurisdiction. All sales will be made through registered securities dealers in jurisdictions where the Offering has been qualified for distribution. The common shares offered are not, and will not be, registered under the securities laws of the United States of America, nor any State thereof, and may not be sold in the United States of America absent registration in the United States or the availability of an exemption from such registration.
