Boardwalk Prices $500 Million Offering of Senior Notes

HOUSTON, Aug. 4, 2020 /PRNewswire/ -- Boardwalk Pipeline Partners, LP (the "Company") today announced that its wholly owned subsidiary, Boardwalk Pipelines, LP ("Boardwalk"), has priced a public offering of $500.0 million aggregate principal amount of 3.40% senior notes due 2031. Boardwalk expects the offering to close on August 11, 2020, subject to customary closing conditions.

Boardwalk intends to use a portion of the net proceeds of approximately $495.1 million from this offering (after deducting the underwriting discount and estimated offering expenses) to retire all of the outstanding $440.0 million aggregate principal amount of the 4.50% notes due 2021 of Texas Gas Transmission, LLC at or near maturity. The remainder of the net proceeds will be used for general partnership purposes, which may include, among other things, growth capital expenditures, repayment of future maturities of long-term debt and additions to working capital. Pending such use, Boardwalk intends to temporarily use the proceeds to reduce borrowings under its revolving credit facility.

Barclays, J.P. Morgan, Mizuho Securities, MUFG, BMO Capital Markets, Citigroup, Regions Securities LLC, TD Securities, Truist Securities, US Bancorp and Wells Fargo Securities are acting as the joint book-running managers for the offering.
