ATP Announces Second Quarter 2008 Results

HOUSTON--(Business Wire)--
ATP Oil & Gas Corporation (NASDAQ:ATPG) today announced second
quarter 2008 results and hedging update.

Highlights include:

-- A production increase of 26% over second quarter 2007;

-- An increase in oil and gas revenues of 45% over second quarter
2007;

-- The sale of an interest in our Gomez Hub for $82.0 million
representing 4.5% of our Gomez Hub proved reserves at December
31, 2007;

-- The acquisition of proved reserves at Clipper for a minimal
upfront investment;

-- The refinancing of our debt, significantly extending the
maturity; and

-- The addition in July 2008 of costless oil collars for 2010 and
2011 with $105 per Bbl floor prices and ceiling prices ranging
from $187 to $197 per Bbl.

Oil and gas production increased 26% to 3.1 MMBoe (18.5 Bcfe) for
the second quarter of 2008, compared to 2.4 MMBoe (14.6 Bcfe) for the
second quarter of 2007. Oil production was 1.4 MMBbls and natural gas
production was 10.0 Bcf for the second quarter of 2008, compared to
1.0 MMBbls and 8.4 Bcfe for the second quarter of 2007. Oil and gas
production increased 31% to 6.7 MMBoe (40.0 Bcfe) for the six months
ended June 30, 2008, compared to 5.1 MMBoe (30.5 Bcfe) for the six
months ended June 30, 2007.

Revenues from oil and gas production increased 45% to $191.8
million for the second quarter of 2008, compared to $132.2 million for
the second quarter of 2007. Revenues from oil and gas production
increased 51% to $417.8 million for the six months ended June 30,
2008, compared to $276.9 million for the six months ended June 30,
2007.

ATP recorded a net loss of $11.8 million or $0.33 per basic and
diluted share for the second quarter of 2008, compared to net income
of $6.1 million or $0.20 per basic and diluted share for the second
quarter of 2007. ATP recorded net income of $35.1 million or $0.98 per
basic share and $0.97 per diluted share for the six months ended June
30, 2008, compared to $33.6 million or $1.12 per basic share and $1.10
per diluted share for the six months ended June 30, 2007.

Results for the second quarter of 2008 were impacted by two items
that research analysts typically exclude from their published
estimates, a charge related to the extinguishment of our prior debt of
$24.2 million ($15.7 million after tax) and a net unrealized loss on
derivatives no longer accounted for as hedges of $49.2 million ($26.8
million after tax). The $24.2 million charge related to the costs of
our previous debt which was required to be written off as a result of
the closing of a new senior secured term loan facility which extended
the maturity of ATP's long-term debt and will provide flexibility with
regard to the announced asset monetization program. Net income before
these items, a non-GAAP measure, in the second quarter of 2008 was
$30.8 million or $0.87 per basic share and $0.86 per diluted share.
The same metric in the second quarter of 2007 is $11.9 million or
$0.40 per basic and $0.39 per diluted share. A non-GAAP reconciliation
is provided near the end of this press release.

In the second quarter of 2008, ATP sold a limited term overriding
royalty interest at its Gomez Hub in the Gulf of Mexico for $82.0
million representing 5.8 Bcfe of proved reserves from this property.
While this transaction is considered a sale for accounting purposes,
the relevant guidance prevents ATP from recognizing a gain on this
transaction. As such, the sale proceeds are recorded as deferred
revenue on the balance sheet and will be recognized as oil and gas
revenues as the reserves attributable to the sold interest are
produced. During the second quarter of 2008 the production
attributable to the sold interest was 0.5 Bcfe. The related reserves
attributable to the sold interest have been removed from ATP's proved
reserves and the production will be excluded from ATP's reported
production.

Due to the sale, ATP's forecasted production from the Gomez Hub
has been reduced accordingly. In addition, as a result of changes in
timing of forecasted production related to the U.K. derivatives,
certain contracts were restructured. In each case the derivative
contracts related to the previously forecasted production no longer
qualify for hedge accounting treatment and, as a result, unrealized
losses previously deferred were charged to earnings in the current
period. Accordingly, during the second quarter of 2008, ATP recorded
derivatives expense of $50.2 million, which consists of the previously
noted $49.2 million noncash unrealized loss and a $1.0 million
realized loss. Subsequent changes in the fair value of these
derivatives will be recorded on a mark-to-market basis in the income
statement. In conjunction with changes in the timing of forecasted
production in the UK, ATP unwound 2.2 Bcfe of natural gas swaps with
an average price of $7.35 scheduled from October 2008 through March
2009, and replaced them with 3.1 Bcfe of natural gas swaps with an
average price of $9.28 from April 2009 through March 2010.

During the second quarter of 2008, ATP acquired a 55% working
interest in Clipper (Green Canyon Blocks 299 and 300), which includes
proved reserves. ATP acquired a 100% working interest in Mississippi
Canyon Block 304, expanding the Canyon Express Hub.

ATP has expanded its oil hedging program to include costless
collars. These are listed below. A detailed hedge and derivative
schedule is provided near the end of this press release.
