Exhibit 99.1 HILAND PARTNERS, LP REPORTS FIRST QUARTER RESULTS ENID, Okla., May 11 /PRNewswire-FirstCall/ -- Hiland Partners, LP (Nasdaq: HLND) (the "Partnership") today reported quarterly net income for the three months ended March 31, 2006 of $3.6 million compared to net income of $1.6 million for the three months ended March 31, 2005, an increase of 117%. Net income per limited partner unit for the first quarter of 2006 increased to $0.37 per unit from income of $0.16 per unit in the corresponding quarter in 2005, an increase of 131%. Adjusted EBITDA (adjusted EBITDA is defined as net income plus interest expense, provisions for income taxes and depreciation, amortization and accretion expense, as adjusted for non-cash realized (gain) loss on derivative transactions and non-cash unit based compensation expense) for the three months ended March 31, 2006 was $8.4 million compared to $3.7 million for the three months ended March 31, 2005, an increase of 129%. Total segment margin for the three months ended March 31, 2006 was $11.9 million compared to $5.6 million for the three months ended March 31, 2005, an increase of 113%. The increases are primarily attributable to higher average realized natural gas and NGL sales prices and the inclusion of the results of operations from the assets contributed to us by Hiland Partners, LLC (the Worland gathering system and compression assets) as part of our initial public offering on February 15, 2005 and the acquisition of Hiland Partners, LLC (the Bakken gathering system) effective September 1, 2005. Our financial results for the quarter ended March 31, 2006 include the acquisition of the membership interests of Hiland Partners, LLC (the Bakken gathering system) effective on September 1, 2005. The results of operations for the quarter ended March 31, 2005 include the financial results of Continental Gas, Inc. (our predecessor) through February 14, 2005 and the results of operations of Hiland Partners, LP for the period from February 15, 2005, the date Hiland Partners, LP commenced operations. As a result, our results of operations are not comparable on a period-to-period basis. "We are pleased with our first quarter results and the continued growth of the Bakken gathering asset that allows us to continue our distribution growth," said Randy Moeder, President and Chief Executive Officer of Hiland Partners, LP. "As we look forward this year, we expect to see that growth continues with the acquisition of the Kinta area gathering assets from Enogex and with the implementation of the other organic growth projects previously announced for 2006." On April 26, 2006, the Partnership announced an increase in its cash distribution for the first quarter of 2006. The declared quarterly distributions on the Partnership's common and subordinated units increased from $0.625 per unit (an annualized rate of $2.50 per unit) for the fourth quarter of 2005, to $0.65 per unit (an annualized rate of $2.60 per unit) for the first quarter of 2006. This distribution will be payable on May 15, 2006 to unitholders of record on May 5, 2006.

We review total segment margin monthly for consistency and trend analysis. We define midstream segment margin as midstream revenue less midstream purchases. Midstream purchases include the following costs and expenses: cost of natural gas and NGLs purchased by us from third parties, cost of natural gas and NGLs purchased by us from affiliates, and cost of crude oil purchased by us from third parties. We define compression segment margin as the revenue derived from our compression segment. (F) We define EBITDA, a non-GAAP financial measure, as net income plus interest expense, provisions for income taxes and depreciation, amortization and accretion expense. We define adjusted EBITDA, a non-GAAP financial measure, as net income plus interest expense, provisions for income taxes and depreciation, amortization and accretion expense, as adjusted for non-cash realized (gain) loss on derivative transactions and non-cash unit based compensation expense. EBITDA and adjusted EBITDA are used as supplemental financial measures by our management and by external users of our financial statements such as investors, commercial banks, research analysts and others to assess: (1) the financial performance of our assets without regard to financial methods, capital structure or historical cost basis; (2) the ability of our assets to generate cash sufficient to pay interest costs and support our indebtedness; (3) our operating performance and return on capital as compared to those of other companies in the midstream energy sector, without regard to financing or structure; and (4) the viability of acquisitions and capital expenditure projects and the overall rates of return on alternative investment opportunities. EBITDA is also a financial measurement that, with certain negotiated adjustments, is reported to our banks and is used as a gauge for compliance with our financial covenants under our credit facility. EBITDA and adjusted EBITDA should not be considered as alternatives to net income, operating income, cash flows from operating activities or any other measures of financial performance presented in accordance with GAAP. Our EBITDA and adjusted EBITDA may not be comparable to EBITDA and adjusted EBITDA of similarly titled measures of other entities, as other entities may not calculate EBITDA and adjusted EBITDA in the same manner as we do.
