Oil States Announces Second Quarter Earnings

HOUSTON, July 30, 2013 (GLOBE NEWSWIRE) -- Oil States International, Inc. (NYSE:OIS) reported net income for the quarter ended June 30, 2013 of $76.5 million, or $1.38 per diluted share, which included $0.12 per diluted share after-tax of non-recurring items which are detailed below. These results compare to net income of $111.2 million, or $2.01 per diluted share, in the second quarter of 2012, which included an after-tax gain of $0.03 per diluted share from insurance proceeds received from a drilling rig fire.

During the second quarter of 2013, the Company recorded several non-recurring items totaling $6.7 million in revenues, $8.1 million of EBITDA and $0.12 per diluted share after-tax. During the quarter, the Company recorded a pre-tax charge of $3.0 million, or $0.05 per diluted share after-tax, from an increase in an acquisition-related contingent liability in the completion services business. In addition, the completion services business reduced a prior period revenue accrual for its foreign operations, negatively impacting revenues and EBITDA by $1.6 million, or $0.02 per diluted share after-tax. The Company also incurred $1.9 million, or $0.03 per diluted share after-tax, of strategic transaction costs during the quarter and the strengthening of the U.S. dollar late in the quarter negatively impacted foreign derived revenues and EBITDA in the accommodations segment by approximately $5.1 million and $1.6 million, respectively, or $0.02 per diluted share after-tax.

The Company generated revenues of $1.0 billion and EBITDA of $195.8 million during the second quarter of 2013, which included $6.7 million of revenue impact and $8.1 million of EBITDA impact from the non-recurring issues outlined above (EBITDA^(A) is defined as net income plus interest, taxes, depreciation and amortization). These results compared to revenues of $1.1 billion and EBITDA of $227.8 million in the second quarter of 2012, which included a pre-tax gain of $2.5 million from insurance proceeds. Consolidated operating income totaled $126.6 million in the current quarter, down from $169.3 million in the second quarter of 2012. Excluding the items noted above from both the second quarter of 2013 and 2012, EBITDA would have decreased 10% year-over-year.

Cindy B. Taylor, Oil States' President and Chief Executive Officer stated, "Our accommodations business reported lower RevPAR levels in the second quarter of 2013 driven by lower occupancy levels in Australia and Canada coupled with lower contracted and foreign exchange rates. We were also negatively impacted during the quarter by poor weather conditions and flooding in Canada and the Bakken region resulting in lower than expected completion services activity and lower utilization for our mobile accommodations assets. Despite the wet weather, our completion services segment outperformed the U.S. rig count, and revenue per ticket increased 12% year-over-year."

"Our Offshore products segment continued its strong performance with revenues increasing 7% year-over-year and EBITDA margins totaling 20% reflecting solid execution. Backlog remains strong, totaling $561 million at June 30, 2013, and global bidding and quoting environment remains very active."

The Company recognized an effective tax rate of 29.2% in the second quarter of 2013 compared with 28.6% in the second quarter of 2012. The higher effective tax rate in the second quarter of 2013 was primarily due to slightly higher foreign effective tax rates.

The Company invested $133.0 million in capital expenditures during the second quarter of 2013 primarily related to the ongoing expansion of its accommodations business in Canada, Australia and the U.S. in addition to incremental proprietary completion services equipment deployed to service the active U.S. shale plays. The Company currently expects to spend approximately $550 million to $600 million in capital expenditures during 2013. During the second quarter of 2013, the Company repurchased $1.5 million, or 20,000 shares, of its common stock under its authorized share repurchase program at an average price of $74.27 per share.

For the first half of 2013, the Company reported revenues of $2.1 billion, EBITDA of $423.9 million and net income of $178.7 million, or $3.22 per diluted share.   For the first half of 2012, the Company reported revenues of $2.2 billion, EBITDA of $484.4 million and $246.3 million of net income, or $4.45 per diluted share. The year-to-date results for 2012 included a pre-tax benefit of $17.9 million, or $0.23 per diluted share after-tax, related to a favorable contract settlement in its U.S. accommodations business recognized in the first quarter of 2012 and a pre-tax gain of $2.5 million, or $0.03 per diluted share after-tax, related to insurance proceeds.

BUSINESS SEGMENT RESULTS

(Unless otherwise noted, the following discussion compares the quarterly results from the second quarter of 2013 to the results from the second quarter of 2012.)

Accommodations

Accommodations generated revenues of $244.2 million and EBITDA of $96.2 million for the second quarter of 2013 compared to revenues and EBITDA of $261.0 million and $114.9 million, respectively, in the second quarter of 2012. Excluding the non-recurring items mentioned earlier, revenues and EBITDA decreased 4% and 15% year-over-year, respectively. Revenues declined year-over-year primarily due to lower mobile camp activity in both the U.S. and Canada, reduced third party manufacturing revenues and lower RevPAR.  EBITDA margins declined to 39% in the second quarter of 2013 compared to 44% in the second quarter of 2012.  The decline in the mobile camp business was exacerbated by a year-over-year decrease in RevPAR related to lower contracted rates in Canada and lower occupancy levels primarily in Australia as a result of a slowdown in mining activity, partially offset by a 12% year-over-year increase in average available rooms.

Well Site Services

Well site services generated revenues of $186.4 million and EBITDA of $57.1 million in the second quarter of 2013 compared to revenues and EBITDA of $176.5 million and $58.5 million, respectively, in the second quarter of 2012.   Excluding the non-recurring items mentioned above, revenues and EBITDA increased 6% and 5% year-over-year, respectively, and EBITDA margins for the segment increased to 33%.  Despite the 11% year-over-year decrease in U.S. drilling activity, results for this segment improved primarily due to greater service intensity in the active shale basins along with contributions from the Tempress acquisition, partially offset by lower utilization within the drilling business, particularly in the Permian basin.  Excluding the impact of the Tempress acquisition, the number of service tickets decreased 5% year-over-year while revenue per ticket increased 17% year-over-year as the industry favored our higher specification equipment.

Offshore Products

Offshore products generated revenues and EBITDA of $204.4 million and $41.6 million in the second quarter of 2013 compared to revenues and EBITDA of $191.6 million and $41.0 million in the second quarter of 2012. Revenues and EBITDA increased 7% and 1% year-over-year, respectively, primarily due to higher levels of manufacturing and service activity, improved revenue mix favoring our subsea equipment and drilling related products, along with contributions from the Piper Valves acquisition.  EBITDA margins were strong at 20% in the current quarter compared to 21% in the second quarter of 2012, and up sequentially from 18% in the first quarter of 2013.  Backlog was essentially flat at $561 million at June 30, 2013 compared to $564 million reported at March 31, 2013 and $561 million reported at December 31, 2012.

Tubular Services

Tubular services generated revenues of $405.5 million and EBITDA of $16.8 million during the second quarter of 2013 compared to revenues of $461.9 million and EBITDA of $25.0 million in the second quarter of 2012. Revenues and EBITDA declined 12% and 33% year-over-year, respectively, primarily due to the 11% year-over-year decrease in U.S. drilling activity and lower OCTG market pricing.  Gross margin as a percent of revenues in the second quarter of 2013 decreased to 5.1% from 6.3% in the second quarter of 2012 primarily due to lower OCTG pricing and resulting pressure on margins. The Company ended the quarter with $438.5 million of OCTG inventories at June 30, 2013, up $16.8 million from March 31, 2013 and down $11.7 million from December 31, 2012.

(A) The term EBITDA consists of net income plus interest, taxes, depreciation and amortization. EBITDA is not a measure of financial performance under generally accepted accounting principles and should not be considered 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. The following table sets forth a reconciliation of EBITDA to net income, which is the most directly comparable measure of financial performance calculated under generally accepted accounting principles.
