Exhibit 99.1 Oil States Announces First Quarter 2003 Earnings HOUSTON, April 28 /PRNewswire-FirstCall/ -- Oil States International, Inc. (NYSE: OIS) today reported a net income increase of 36.3% to $13.4 million, or $0.27 per diluted share, for the quarter ended March 31, 2003 compared to net income of $9.8 million, or $0.20 per diluted share, in the first quarter of 2002. The Company's revenues increased by 23.2% over the first quarter of 2002 due to the rebound in North American drilling activity, continued strong deepwater development activity and contributions from acquisitions completed in the third quarter of 2002. Revenues were $185.6 million for the quarter compared to $150.6 million for the first quarter of 2002. EBITDA (defined as operating income plus depreciation and amortization expense) increased 44.9% to $26.8 million in the current quarter compared to $18.5 million for the first quarter of 2002(A). The Company's effective tax rate in the first quarter of 2003 was 29.0% compared to an effective tax rate of 22.0% in the first quarter of 2002. Capital expenditures during the quarter totaled $5.7 million. BUSINESS SEGMENT RESULTS Well Site Services The Well Site Services segment generated improved results as North American drilling activity increased by 16.7% on a year over year basis. Well Site Services' revenues and EBITDA were $78.8 million and $19.5 million, respectively, in the first quarter of 2003 compared to $66.6 million and $15.2 million, respectively, in the first quarter of 2002. Although the Canadian winter drilling season did not begin in earnest until mid-January, Canadian drilling activity in the first quarter of 2003 reached strong levels which positively impacted the Company's well site accommodations operations. The Company's land drilling and rental tool operations benefited during the quarter from the rebound in US land drilling activity. In addition, the Company's workover business experienced increased activity during the quarter. Although asset utilization generally improved in the first quarter of 2003, the Company was not able to significantly increase prices in any of its Well Site Services business lines. Offshore Products For the first quarter of 2003, Offshore Products generated $57.6 million of revenues and $7.5 million of EBITDA, compared to $32.7 million of revenues and $4.4 million of EBITDA in the first quarter of 2002. Gross margins decreased to 21.6% in the first quarter of 2003 from 25.2% in the first quarter of 2002 partially due to the Company's recognition during the quarter of a loss on one of its subsea pipeline projects. Offshore Products' backlog was $80.9 million at March 31, 2003 compared to $100.1 million at December 31, 2002 and $87.4 million at March 31, 2002. Tubular Services Tubular Services generated $49.2 million of revenues and $1.1 million of EBITDA in the first quarter of 2003 compared to $51.3 million of revenues and $0.1 million of EBITDA in the first quarter of 2002. The average US rig count increased 10.2% to 897 rigs in the first quarter of 2003 compared to 814 average rigs running in the first quarter of 2002. With the rising US drilling activity, Tubular Services' OCTG shipments increased approximately 12% to 57,000 tons in the first quarter of 2003 compared to 51,000 tons in the first quarter of 2002. However, the Company's revenues per ton decreased by approximately 17% due to product mix and lower market prices. As a result, Tubular Services revenues declined year-over-year by 4.1%. Gross margin for the first quarter of 2003 was 5.9% versus 4.3% in the first quarter of 2002. The increase in gross margin was a result of positive mix of customer orders. OCTG inventory at March 31, 2003 was $65.1 million compared to $37.6 million at March 31, 2002 and $60.4 million at December 31, 2002. As of March 31, 2003, approximately 64% of Oil States' OCTG inventory was committed to customer orders. "North American land drilling activity improved in the first quarter of 2003," stated Douglas E. Swanson, Oil States' President and Chief Executive Officer. "We benefited from stronger results in our Well Site Services and Tubular Services segments as North American drilling activity rebounded while our Offshore Products segment continued to produce strong operating and financial results. Looking forward, we will be impacted by the normal, seasonal decline in drilling activity in Canada in the second quarter. We expect our US drilling-related businesses to continue to benefit from the strengthening US rig count and for our Offshore Products segment to continue to perform well given our backlog."

(A) The term EBITDA consists of operating income plus depreciation and amortization expense. EBITDA is not a measure of financial performance under generally accepted accounting principles. You should not consider it in isolation from or as a substitute for net income or cash flow measures prepared in accordance with generally accepted accounting principles or as a measure of profitability or liquidity. Additionally, EBITDA may not be comparable to other similarly titled measures of other companies. The Company has included EBITDA as a supplemental disclosure because its management believes that EBITDA provides useful information regarding our ability to service debt and to fund capital expenditures and provides investors a helpful measure for comparing its operating performance with the performance of other companies that have different financing and capital structures or tax rates. The Company uses EBITDA to compare and to monitor the performance of its business segments to other comparable public companies and as a benchmark for the award of incentive compensation under its annual incentive compensation plan.
