Spectra Energy Partners Reports Strong Third Quarter 2011 Results Over Prior Year

• Reported net income of $43.5 million, up 13 percent

• Cash available for distribution of $69.3 million, up from $50.4 million

• Quarterly cash distributions per unit of $0.47, up from $0.44 in prior year quarter

HOUSTON – Spectra Energy Partners, LP (NYSE: SEP) today reported third quarter 2011 net income of $43.5 million, or $0.40 per limited partner unit, compared with $38.4 million, or $0.44 per limited partner unit, for the third quarter 2010.

Increased net income resulted primarily from the acquisitions of an additional 24.5 percent interest in Gulfstream in the fourth quarter 2010 and the Big Sandy Pipeline on July 1, 2011, partially offset by anticipated lower revenues at Ozark. Earnings per limited partner unit for the quarter reflect a higher number of weighted average units outstanding compared to the prior period.

Cash available for distribution was $69.3 million for the quarter, compared with $50.4 million in the third quarter 2010.

“Spectra Energy Partners’ third quarter results were driven by our recent acquisitions,” said Gregory J. Rizzo, president and chief executive officer. “The Northeastern Tennessee (NET) expansion project, which was placed in service on September 1, also contributed to our results. The strong quarter supported Spectra Energy Partners’ 16th consecutive quarterly cash distribution increase.”

“We also announced during the quarter that Julie Dill will become president and chief executive officer of Spectra Energy Partners on January 1, 2012,” Rizzo continued. “Julie, who is currently president of Spectra Energy’s Ontario-based gas distribution business, Union Gas, will provide outstanding leadership for Spectra Energy Partners as the partnership continues to execute its strategy of balanced growth.”

Results from Operations

Spectra Energy Partners reported operating income of $23.2 million for the third quarter 2011, compared with $24.3 million in the third quarter 2010. Earnings from the Big Sandy acquisition and the East Tennessee NET expansion placed into service September 1 were offset by anticipated lower revenues at Ozark and Big Sandy Pipeline transition costs.

Equity Investment in Gulfstream Natural Gas System, L.L.C. (Gulfstream)

Spectra Energy Partners recognized $16.2 million of earnings from its 49 percent interest in Gulfstream in the third quarter 2011, compared with $8.2 million from its 24.5 percent interest in the prior-year third quarter.

For the quarter, Spectra Energy Partners’ share of Gulfstream’s cash available for distribution was $29.4 million, compared to $14.7 million in the third quarter 2010.

Equity Investment in Market Hub Partners (MHP)

Spectra Energy Partners recognized $11.1 million of earnings from its 50 percent interest in MHP in the third quarter 2011, compared with $10.2 million in the third quarter 2010. The increased earnings primarily reflect the full commercial in-service of our multi-year expansion projects.

For the quarter, Spectra Energy Partners’ share of MHP’s cash available for distribution was $11.8 million, compared to $11.4 million in the third quarter 2010.

Interest Expense and Other

Interest expense for the quarter was $7.7 million, compared to $4.3 million for the prior year due to the $500 million of senior notes issued in June 2011.

Reconciliation of Non-GAAP Financial Measures

This press release includes certain financial measures, including cash available for distribution and adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA), that are non-GAAP (Generally Accepted Accounting Principles) financial measures, as defined under the rules of the Securities and Exchange Commission (SEC).

Spectra Energy Partners defines adjusted EBITDA as net income plus interest expense, income taxes, and depreciation and amortization, less equity in earnings of Gulfstream and MHP, interest income, and other income and expenses, net, which primarily includes non-cash AFUDC.

Spectra Energy Partners defines cash available for distribution as adjusted EBITDA plus cash available for distribution from Gulfstream and MHP and net preliminary project costs, less net cash paid for interest expense (income), net cash paid for income taxes and maintenance capital expenditures. Cash available for distribution does not reflect changes in working capital balances. Cash available for distribution for Gulfstream and MHP is defined on a basis consistent with Spectra Energy Partners.

This press release is accompanied by a reconciliation of these non-GAAP financial measures to their nearest GAAP financial measures. Management uses these financial measures because they are accepted financial indicators used by investors to compare company performance. In addition, management believes that these measures provide investors an enhanced perspective of the operating performance of the Partnership’s assets and the cash that the business is generating. Adjusted EBITDA and cash available for distribution are not presented as alternatives to net income or cash flow from operations. They should not be considered in isolation or as substitutes for a measure of performance prepared in accordance with United States GAAP.
