October 22, 2003 UNIT CORPORATION REPORTS THIRD QUARTER & FIRST NINE MONTH RESULTS IN 2003 Tulsa, Oklahoma . . . Unit Corporation (NYSE - UNT) announced today its financial and operational results for the third quarter and first nine months of 2003. Consolidated net income for the third quarter was $12.8 million, or 29 cents per diluted share, on revenues of $78.2 million, compared to 2002's third quarter net income of $3.7 million, or 9 cents per diluted share, on revenues of $48.3 million. Revenues increased 62 percent while net income increased 244 percent between the comparative quarters. The dramatic improvement in net income and revenue was due to a significant increase in natural gas prices and improvements in drilling rig utilization and dayrates. For the nine-month period, the Company reported consolidated net income of $38.4 million, or 88 cents per diluted share. Net income for the first nine months of 2003 included $1.3 million of income, net of tax for the impact of the adoption of SFAS 143, "Accounting for Asset Retirement Obligations," which became effective in the first quarter of 2003. SFAS 143 requires oil and natural gas operating companies to recognize in current periods the present value of the estimated future cost for the plugging of its oil and natural gas wells and upon implementation requires the recalculation of depreciation, depletion and amortization for prior years. Income before the change in accounting principle for the first nine months of 2003 was $37.1 million, or 85 cents per diluted share, on revenues of $219.6 million, compared to 2002's first nine month net income of $11.5 million, or 30 cents per diluted share, on revenues of $131.8 million. UNIT PETROLEUM RESULTS Revenues from Unit's oil and natural gas operations for the third quarter of 2003 versus the third quarter of 2002 increased 68 percent to $27.4 million due to higher oil and natural gas prices and an increase in oil and natural gas production. During the first nine months of 2003, oil and natural gas revenues were $87.5 million, an increase of 86 percent over the same period in 2002. Natural gas production was 5,233 million cubic feet (MMcf) in the third quarter of 2003, while oil production for the same period was 134,000 barrels, which on an equivalent Mcf basis was 11 percent more than the third quarter of 2002. Natural gas production was 15,043 MMcf in the first nine months of 2003, while oil production for the same period was 372,000 barrels, a 5 percent increase on an equivalent Mcf basis over the first nine months of 2002. The exit rate production for the first nine months of 2003 was 1,660 barrels of oil per day and 59,039 Mcf of natural gas per day. Average natural gas prices received during the third quarter of 2003 increased 66 percent to $4.50 per Mcf compared to $2.71 per Mcf during the third quarter of 2002. The average oil price received was $25.51 per barrel in the third quarter of 2003 compared to $22.99 per barrel in the 2002 comparative quarter, an 11 percent increase. For the first nine months of 2003, average natural gas prices received increased 95 percent to $5.05 per Mcf compared to $2.59 per Mcf during the first nine months of 2002. The average oil price received was $27.02 per barrel in the first nine months of 2003 compared to $20.92 per barrel in 2002, a 29 percent increase. During the first nine months of 2003, Unit completed 98 wells with a success rate of 85 percent. UNIT DRILLING RESULTS Contract drilling revenues increased 58 percent between the comparative third quarters to $50.1 million, due to increases in both the number of rigs utilized and dayrates. Average rig utilization in the third quarter of 2003 was 68.2 rigs, up 60 percent from 2002's third quarter. Currently, Unit has 68 rigs operating under contract. Average dayrates for the third quarter increased to an average of $8,015 per day, 6 percent higher than the comparable quarter of 2002. Between the comparative first nine months, contract drilling revenues increased 54 percent in 2003 to $129.8 million with rig utilization increasing to an average of 60.6 rigs operating in the first nine months of 2003, compared to 36.2 rigs in the first nine months of 2002. Contract drilling cash operating margins per rig averaged $1,977 per day during the first nine months of 2003, compared to $2,076 for the same period in 2002. The exit rate cash operating margin for the end of the first nine months of 2003 was $2,350 per day. MANAGEMENT COMMENTS "Our third quarter results reflect the impact of a higher commodity pricing environment," said John Nikkel, Chief Executive Officer and Chairman of the Board. "Unit has positioned itself to benefit from current industry conditions. With 98 wells completed during the first nine months of 2003, our exploration and production segment is on track to drill 140 to 150 wells by year-end. During August, Unit announced that it signed a merger agreement with PetroCorp Incorporated for a purchase price of $182 million to be paid in cash. PetroCorp explores and develops oil and natural gas properties primarily in Texas and Oklahoma. The acquisition will allow us to economically grow our asset base. We expect the acquisition to close before year-end. Our contract drilling segment has seen a 5 percent rise in average dayrates from the previous quarter and our current rig utilization is 91 percent of 75 total rigs available for service. Unit's 76th rig has been constructed and will be placed into service in approximately two weeks. This is a 1,500 horsepower, diesel-electric rig capable of drilling to 20,000 feet. A 77th rig is currently under construction and is expected to be completed and available for service during the first quarter of 2004. "Long-term debt has decreased by 51 percent since the beginning of 2003. We are pleased with the opportunities and outcomes that the industry has provided for our operations to grow. We will continue along that path as the year unwinds." WEBCAST Unit will webcast its third quarter earnings conference call live over the Internet on October 22, 2003 at 11:30 a.m. Eastern Time.
