Westlake Chemical Partners LP Announces Third Quarter 2016 Earnings

Westlake Chemical Partners LP (NYSE: WLKP) (the "Partnership") today reported net income attributable to the Partnership of $8.7 million, or $0.32 per limited partner unit, for the three months ended September 30, 2016, a decrease of $1.4 million compared to third quarter 2015 net income attributable to the Partnership of $10.1 million, or $0.37 per limited partner unit. The decrease in net income attributable to the Partnership as compared to the prior-year period was primarily due to lower operating rates at Westlake Chemical OpCo LP’s (“OpCo”) Petro 1 facility in Lake Charles, Louisiana due to the planned turnaround and expansion project, which was completed in July. The third quarter 2016 results were also negatively impacted by lost production as a result of an unplanned outage at OpCo’s Calvert City, Kentucky facility.

The third quarter 2016 net income attributable to the Partnership of $8.7 million, or $0.32 per limited partner unit, decreased by $0.6 million from the second quarter 2016 net income attributable to the Partnership of $9.3 million, or $0.34 per limited partner unit. The decrease in net income was due to a decrease in sales to Westlake Chemical (“Westlake”) associated with certain cost recovery provisions in the ethylene sales agreement between OpCo and Westlake, which was partially offset by increased production at OpCo’s Petro 1 and Calvert City facilities.

On October 31, 2016, the Board of Directors of Westlake Chemical Partners GP LLC, the general partner of the Partnership, announced a quarterly distribution with respect to the third quarter of 2016 of $0.3353 per limited partner unit to be payable on November 29, 2016 to unit and IDR holders of record as of November 14, 2016. The third quarter 2016 distribution increased 12.0% compared to the third quarter 2015 distribution and 2.88% compared to the second quarter 2016 distribution.

OpCo's sales agreement with Westlake is designed to provide for stable and predictable cash flows. The sales agreement provides that 95% of OpCo's ethylene output is sold to Westlake for a cash margin of $0.10 per pound, net of operating costs, maintenance capital expenditures and reserves for future turnaround expenditures. Under the ethylene sales agreement with Westlake, Westlake’s obligation to purchase the annual minimum commitment under the ethylene sales agreement, which is measured at year end, is not reduced for the first 45 days following a force majeure event, such as the unplanned outage at Calvert City that began in June 2016.

“We are pleased with OpCo’s recent performance following our turnaround and expansion project, which was completed in July, and added 250 million pounds of capacity to our Petro 1 facility. We believe our upcoming 100 million pound ethylene expansion at our Calvert City facility in the first half of 2017, along with the recently completed expansion at Petro 1, support our continued increase in distributions at a low double digit growth rate to unitholders,” said Albert Chao, President and Chief Executive Officer.

The statements in this release and the related teleconference relating to matters that are not historical facts, such as statements regarding growth of distributions and results of expansion projects, are forward-looking statements. These forward-looking statements are subject to significant risks and uncertainties. Actual results could differ materially, based on factors including, but not limited to, operating difficulties; the volume of ethylene that we are able to sell; the price at which we are able to sell ethylene; changes in the price and availability of electricity; changes in prevailing economic conditions; actions of Westlake Chemical Corporation; actions of third parties; unanticipated ground, grade or water conditions; inclement or hazardous weather conditions, including flooding, and the physical impacts of climate change; environmental hazards; industrial accidents; changes in laws and regulations (or the interpretation thereof); inability to acquire or maintain necessary permits; inability to obtain necessary production equipment or replacement parts; technical difficulties or failures; labor disputes; late delivery of raw materials; difficulty collecting receivables; inability of our customers to take delivery; changes in the price and availability of transportation; fires, explosions or other accidents; our ability to borrow funds and access capital markets; and other risk factors. For more detailed information about the factors that could cause actual results to differ materially, please refer to the Partnership's Annual Report on Form 10-K for the year ended December 31, 2015, which was filed with the SEC in March 2016, and the risk factors in our other filings with the SEC.

This release is intended to be a qualified notice under Treasury Regulation Section 1.1446-4(b). Brokers and nominees should treat one hundred percent (100.0%) of the Partnership's distributions to non-U.S. investors as being attributable to income that is effectively connected with a United States trade or business. Accordingly, the Partnership's distributions to non-U.S. investors are subject to federal income tax withholding at the highest applicable effective tax rate.

Use of Non-GAAP Financial Measures

This release includes the term MLP distributable cash flow, which is a non-GAAP financial measure, as defined in Regulation G of the U.S. Securities Exchange Act of 1934, as amended. We report our financial results in accordance with U.S. generally accepted accounting principles ("GAAP"), but believe that certain non-GAAP financial measures, such as MLP distributable cash flow and EBITDA, provide useful supplemental information to investors regarding the underlying business trends and performance of our ongoing operations and are useful for period-over-period comparisons of such operations. These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the financial measures prepared in accordance with GAAP. A reconciliation of MLP distributable cash flow and EBITDA to net income and net cash provided by operating activities can be found in the financial schedules at the end of this release. We define distributable cash flow as net income plus depreciation and amortization, less contributions from turnaround reserves and maintenance capital expenditures. We define MLP distributable cash flow as distributable cash flow less distributable cash flow attributable to Westlake's noncontrolling interest in OpCo and distributions attributable to incentive distribution rights holder. MLP distributable cash flow does not reflect changes in working capital balances. We define EBITDA as net income before interest expense, income taxes, depreciation and amortization. Because MLP distributable cash flow and EBITDA may be defined differently by other companies in our industry, our definition of MLP distributable cash flow and EBITDA may not be comparable to similarly titled measures of other companies.
