HILAND PARTNERS, LP REPORTS 2004 PRO FORMA FOURTH QUARTER AND YEAR-END RESULTS

    ENID, Okla., March 29 /PRNewswire-FirstCall/ -- Hiland Partners, LP (Nasdaq:
HLND) (the "Partnership") today reported pro forma financial results for the
three months and year ended December 31, 2004. The Partnership's reported pro
forma financial results give effect to the transfer of assets to the Partnership
in connection with its formation and the Partnership's initial public offering
as if they had occurred as of the beginning of the periods presented.
Substantially all of the assets and operations of Continental Gas, Inc. and
Hiland Partners, LLC, other than a portion of its working capital assets and the
assets related to the Bakken gathering system, were contributed to the
Partnership in connection with the initial public offering of 2,300,000 common
units representing limited partnership interests in Hiland Partners, LP that
closed on February 15, 2005. Included in the tables below are also the reported
results of Continental Gas, Inc. and Hiland Partners, LLC for the three months
and the year ended December 31, 2004.

    On a pro forma basis, net income for the three months ended December 31,
2004 was $2.7 million, or $0.38 per limited partner unit, compared to a net loss
of $0.2 million, or $0.03 per limited partner unit, for the three months ended
December 31, 2003. Pro forma total segment margin for the three months ended
December 31, 2004 was $8.0 million compared to $5.4 million for the three months
ended December 31, 2003, an increase of 49%. The increase is attributable to
higher average realized natural gas sales prices and NGL sales prices. Pro forma
EBITDA for the three months ended December 31, 2004 nearly tripled to $5.7
million compared to $2.0 million for the three months ended December 31, 2003.
EBITDA is a non-GAAP financial measure that is reconciled to its most directly
comparable GAAP measure in the tables below.

    "Due to our continued focus on organic growth, we are pleased to announce
improved operating results for the fourth quarter," said Randy Moeder, President
and Chief Executive Officer of Hiland Partners. "Our midstream segment directly
benefited from favorable processing margins. We intend to continue to focus
primarily on growth within our core operating areas."

    On a pro forma basis, net income for the year ended December 31, 2004 was
$7.8 million, or $1.13 per limited partner unit, compared to $2.1 million, or
$0.30 per limited partner unit, for the year ended December 31, 2003. Pro forma
total segment margin for the year ended December 31, 2004 was $25.1 million
compared to $19.1 million for the year ended December 31, 2003, an increase of
31%. This increase was primarily attributable to increases in natural gas
volumes and NGL sales volumes primarily as a result of the acquisition of the
Carmen gathering system from Great Plains Pipeline Company in August 2003
combined with higher natural gas and NGL prices. Pro forma EBITDA for the year
ended December 31, 2004 increased 64% to $17.2 million compared to $10.5 million
for the year ended December 31, 2003.

    (A) The Partnership's reported pro forma financial results give effect to
        the transfer of assets to the Partnership in connection with its
        formation and to the Partnership's initial public offering and use of
        the offering proceeds to retire all debt as if they had occurred as of
        the beginning of the periods presented. Substantially all of the assets
        and operations of Continental Gas, Inc. and Hiland Partners, LLC, other
        than a portion of its working capital assets and the assets related to
        the Bakken gathering system, were contributed to the Partnership in
        connection with the initial public offering of 2,300,000 common units
        representing limited partnership interests in Hiland Partners, LP that
        closed on February 15, 2005. In addition, the pro forma financial
        results for the year ended December 31, 2003 give effect to the
        acquisition of the Carmen gathering system, which was acquired on August
        1, 2003, as if such acquisition occurred on January 1, 2003. The assets
        of Continental Gas, Inc. transferred to the Partnership were recorded at
        historical costs as it was considered to be a reorganization of entities
        under common control. The acquisition of the assets of Hiland Partners,
        LLC and the Carmen gathering system were accounted for as purchases and,
        as a result, these assets were recorded at their fair value at the time
        of purchase. The unaudited pro forma information is not necessarily
        indicative of the results of operations that would have occurred had the
        transactions been made at the beginning of the periods presented or the
        future results of the combined operations.

    (B) 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.

    (C) We view total segment margin as an important performance measure of the
        core profitability of our operations.



    (D) Net income (loss) per unit is not applicable for periods prior to our
        initial public offering. Pro forma net income (loss) per limited partner
        unit for the three months ended December 31, 2004 and the three months
        ended December 31, 2003 of $0.38 and ($0.03), respectively, are
        presented pro forma for our initial public offering. Per limited partner
        unit amounts give effect to our general partner's 2% interest in income
        (loss).

    (E) We define EBITDA as net income plus interest expense, provision for
        income taxes and depreciation, amortization and accretion expense.
        EBITDA is a used as a supplemental financial measure 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 financing 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 capital structure; and (4) the viability
        of acquisition 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 facilities.

    (F) EBITDA has not been increased for the impact of the $1.5 million
        non-cash impairment charge for the three months ended December 31, 2003.

    The following table presents a reconciliation of the non-GAAP financial
measures of (1) EBITDA to the GAAP financial measure of net income and (2) total
segment margin (which consists of the sum of midstream segment margin and
compression segment margin) to operating income, in each case, on a historical
and pro forma basis for each of the periods indicated.

    (A) Net income per unit is not applicable for periods prior to our initial
        public offering. Pro forma net income per limited partner unit for the
        year ended December 31, 2004 and the year ended December 31, 2003 of
        $1.13 and $0.30, respectively, are presented pro forma for our initial
        public offering.

    (B) EBITDA has not been (1) increased for the impact of the $1.5 million
        non-cash impairment charge for the year ended December 31, 2003 or (2)
        decreased for the impact of the $1.6 million cumulative effect of
        accounting change for the year ended December 31, 2003.

    The following table presents a reconciliation of the non-GAAP financial
measures of (1) EBITDA to the GAAP financial measure of net income and (2) total
segment margin (which consists of the sum of midstream segment margin and
compression segment margin) to operating income, in each case, on a historical
and pro forma basis for each of the periods indicated.
