Westlake Chemical Partners LP Announces Offering of Common Units

HOUSTON--(BUSINESS WIRE)--Sep. 26, 2017-- Westlake Chemical Partners LP (NYSE: WLKP) (the “Partnership”) announced the commencement of an underwritten public offering of 4,500,000 common units representing limited partner interests in the Partnership. In connection with the offering, the Partnership intends to grant the underwriter a 30-day option to purchase up to an additional 675,000 common units.

The Partnership intends to use the net proceeds from this offering, along with borrowings under its revolving credit facility, to fund its obligations under the concurrently announced acquisition of an additional limited partner interest in Westlake Chemical OpCo LP (“OpCo”), which will increase the Partnership’s limited partner interest in OpCo by 5.0% to approximately 18.3% (the “OpCo Equity Purchase”). Pending the use of proceeds for such purpose, or if the OpCo Purchase is not consummated for any reason, the Partnership intends to use the net proceeds from this offering for general partnership purposes. OpCo intends to use the proceeds it receives from the OpCo Equity Purchase to repay borrowings under its intercompany debt agreements with Westlake Chemical Corporation.

The common units are being offered and will be sold pursuant to an effective shelf registration statement that was previously filed with the Securities and Exchange Commission (“SEC”). This press release shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such states.
