HAMILTON, Bermuda, Feb. 18, 2014 /PRNewswire/ -- Nabors Industries Ltd. (NYSE: NBR) today announced its results for the fourth quarter and full year 2013. The Company's net income from continuing operations was $128.5 million ($0.42 per diluted share) in the fourth quarter and $158.3 million ($0.51 per diluted share) for the full year. For the comparable periods of the prior year, the Company reported net income from continuing operations of $131.6 million ($0.45 per diluted share) for the fourth quarter and $232.2 million ($0.79 per diluted share) for the full year. Fourth quarter adjusted income derived from operating activities was $159.6 million, bringing the total for 2013 to $558.2 million. This compares to $153.7 million for the corresponding quarter of 2012 and $907.0 million for all of 2012. Operating cash flow (EBITDA) was $437.2 million for the fourth quarter compared to $427.1 million in the same quarter last year and $439.3 million in the third quarter of 2013. Full-year operating cash flow was $1.64 billion compared to $1.95 billion for 2012. Revenues for 2013 were $1.60 billion for the quarter and $6.15 billion for the full year, compared to $1.57 billion and $6.54 billion, respectively in 2012.

Tony Petrello, Nabors' Chairman and CEO, commented, "The strength of our fourth-quarter results reflects building momentum in our International operations and a more favorable outlook for our U.S. Drilling operations. Our Completion & Production Services operations posted an improvement in what would usually be a seasonally weaker quarter.

"In addition to good operational performance, income benefited from approximately $4.6 million in early contract termination payments and a $9.0 million gain from a bankruptcy settlement, in which we fully recovered our receivables plus interest. Non-operating results were also favorable as quarterly interest expense fell to $47.1 million, which equates to an annualized savings of approximately $60 million relative to a year ago. This sizeable interest savings is a result of our recent debt refinancing and a year-over-year reduction in total debt of nearly $0.5 billion. We also realized a net tax benefit in the quarter resulting from the premium paid with respect to the debt refinancing and favorable tax adjustments in multiple venues.

"Initiatives to enhance our financial position and streamline our operations continued to yield results throughout 2013, despite the challenges imposed by the lower industry rig count and anemic asset valuations. Cumulatively in the seven quarters since the launch of these efforts in the second quarter of 2012, we have:


    --  Consistently generated free cash flow.
    --  Completed over $700 million in monetization of assets.
    --  Initiated an annual dividend of $0.16 per share.
    --  Secured contracts for 40 new and 11 upgraded rigs that aggregate to over
        140 rig years and $2.8 billion in revenues.
    --  Reinvested $1.4 billion in new technology rigs and enhancements with
        firm contracts securing attractive returns.
    --  Achieved all of the foregoing while reducing net debt by $870 million."

Drilling & Rig Services

Operating income in the Drilling & Rig Services business line was $157.3 million, representing a sequential increase of approximately $25.5 million, adjusted for early termination payments. Operating cash flow of $380.2 million also reflected an adjusted increase of $25.8 million compared to the third quarter. Significant improvements in International, U.S. Drilling and Canada, outpaced a loss in Rig Services where profitability in Canrig was more than offset by losses in two other operations.

International operations showed significant improvement in spite of a flat rig count. This resulted from a further increase in average margins to $15,884 per rig day and surpassing 2008 margins, which was the best year yet for this unit. The increased margins reflect a combination of the full contribution and mix of higher-margin startups, lower rig move results, and further abatement of cost issues in certain markets that have characterized prior periods. The Company expects these costs to further improve, with full mitigation not expected before the end of 2014; however, it continues to anticipate first quarter results to be significantly lower, with more normal rig move results, idle time between contracts for certain high-margin rig operations, and dry-docking of the large Arabian Gulf jackup. Sequential results should begin to improve again in the second quarter and accelerate in the second half driven by the restart of the idle rigs, the previously announced new deployments and contractual rate increases, which are applicable to more than 30 rigs in the next five quarters.

In North America, U.S. Drilling operations improved by an adjusted amount of approximately $12.0 million sequentially. The improvement stemmed from an adjusted increase in average daily rig margins of $400 and three additional rigs working. The adjustments result from early contract termination payments amounting to $4.6 million in the fourth quarter and $34.3 million in the third quarter. The Company expects a flat first quarter with higher costs attributable to payroll taxes followed by an improving year. This favorable outlook is supported by the planned deployment of 20 PACE(®)-X rigs in 2014, firming spot-market pricing, improving activity in Alaska and the late-year commencement of a new high-impact deepwater platform rig. While optimistic about the U.S. land market, the Company still expects a competitive environment as a result of ongoing excess legacy rig capacity, continued productivity gains and competitive speculative new construction.

Rig Services posted a loss in the quarter driven by losses in directional drilling and an Alaska construction joint venture. Canrig was profitable and its back log increased significantly, indicating more favorable results in subsequent quarters.

Completion & Production Services

Operating income in the Completion & Production Services business line was $40.8 million, representing a sequential increase of approximately $1.9 million, in what is customarily a seasonally weaker quarter. Operating cash flow of $96.4 million reflected an increase of $5.6 million compared to the third quarter. The sequential improvement came from both components of this business although Completion Services experienced some late quarter weather effects.

In Production Services, the sequential increase was attributable to higher truck hours that resulted from a fourth quarter acquisition. Rig hours were down eight percent with seasonal effects, partially offset by higher average rates. Improving results in this operation are expected throughout most of 2014, notwithstanding the recent severe weather and second-quarter breakup in Canada. The improving outlook is fueled by the steady increase in the quantity and complexity of oil wells in the U.S. at a time of relatively high industry utilization and a depleting quantity of viable rigs to reactivate.

In Completion Services, sequential results improved modestly with higher utilization in south and west Texas more than offsetting some late-quarter adverse weather in northern operations. The Company now believes pricing in the completion market is stabilizing as a result of a pricing floor imposed by higher maintenance costs associated with the large increase in pumping hours per day. This operation continues to achieve significant reductions in operating and overhead costs. Improvements in profitability are also being realized as a result of the fourth-quarter suspension of a majority of the Company's U.S. coiled tubing operations and the relocation of the Canada stimulation operations to west Texas.

Despite these improvements, the near-term outlook for this operation is substantially lower in the first quarter, primarily as a result of the expiration of the Company's only remaining legacy term contract at the end of 2013. This is exacerbated by excessive downtime associated with the unusually cold weather in its northern operations, which comprise approximately 60 percent of its fleet. Following the difficulties that are plaguing the first quarter, subsequent quarters should improve throughout 2014 as a result of further improvement in costs, increasing utilization and stable-to-improving pricing.

Financial Position:

The Company's financial position continues to improve, with fourth-quarter free cash flow further reducing net debt by $148 million. Net debt now is less than $3.5 billion, with liquidity approximating $1.5 billion. Further progress is anticipated in the near term notwithstanding the capital requirements associated with numerous new rigs under construction.

Summary and Outlook:

Petrello concluded, "Looking forward, we believe 2013 will represent the low point in Nabors' protracted five-year trough. Commencing with the second quarter, we foresee substantial year-over-year quarterly improvement, which should accelerate in the second half. This is supported by our robust international outlook, the ongoing demand for PACE(®)-X rigs, the prospects for near-term increases in US land activity and improving spot pricing, favorable trends in well-servicing and fluids management, and indications of a stabilizing pressure pumping market, although the recent cold weather is having a large adverse near-term impact on that segment. A major factor in our expectation is the outsized contribution of the 140 rig years of long-term rig contracts we have secured over the last 18 months, 90 of which should be realized through 2015 with only 6.7 reflected in our results to date. The gross margin impact of these rigs is more than two and a half times that of an average U.S. land rig as defined by our fourth-quarter average margins. This demonstrates the inherent value of the breadth and quality of Nabors' fleet and global opportunity set that has been elusive over the last few years."

    (1)            See "Computation of Earnings (Losses)
                   Per Share" included herein as a
                   separate schedule.


    (2)            Adjusted EBITDA is computed by
                   subtracting the sum of direct costs,
                   general and administrative expenses,
                   earnings (losses) from our former
                   U.S. oil and gas joint venture from
                   the sum of Operating revenues and
                   Earnings (losses) from
                   unconsolidated affiliates. There are
                   limitations inherent in using
                   adjusted EBITDA as a measure of
                   overall profitability because it
                   excludes significant expense items.
                   However, management evaluates the
                   performance of our business units
                   and the consolidated company based
                   on several criteria, including
                   adjusted EBITDA and adjusted income
                   (loss) derived from operating
                   activities, because we believe that
                   these financial measures accurately
                   reflect our ongoing profitability.
                   These amounts should not be used as
                   a substitute for the amounts
                   reported in accordance with GAAP. To
                   compensate for the limitations in
                   utilizing adjusted EBITDA as an
                   operating measure, management also
                   uses GAAP measures of performance,
                   including income from continuing
                   operations and net income, to
                   evaluate performance, but only with
                   respect to the Company as a whole
                   and not on a segment basis.  A
                   reconciliation of this non-GAAP
                   measure to income (loss) from
                   continuing operations before income
                   taxes, which is a GAAP measure, is
                   provided in the table set forth
                   immediately following the heading
                   "Reconciliation of Non-GAAP
                   Financial Measures to Income (loss)
                   from Continuing Operations before
                   Income Taxes".


    (3)            Adjusted income (loss) derived from
                   operating activities is computed by
                   subtracting the sum of direct costs,
                   general and administrative expenses,
                   depreciation and amortization and
                   earnings (losses) from our former
                   U.S. oil and gas joint venture from
                   the sum of Operating revenues and
                   Earnings (losses) from
                   unconsolidated affiliates. These
                   amounts should not be used as a
                   substitute for those amounts
                   reported in accordance with GAAP.
                   However, management evaluates the
                   performance of our business units
                   and the consolidated company based
                   on several criteria, including
                   adjusted income (loss) derived from
                   operating activities, because it
                   believes that these financial
                   measures accurately reflect our
                   ongoing profitability.  A
                   reconciliation of this non-GAAP
                   measure to income (loss) from
                   continuing operations before income
                   taxes, which is a GAAP measure, is

                      December 31, 2013.


    (3)               Includes earnings (losses), net from
                      unconsolidated affiliates, accounted
                      for using the equity method, of
                      ($.2) million, $.5 million and $.3
                      million for the three months ended
                      December 31, 2013 and 2012 and
                      September 30, 2013, respectively,
                      and $.4 million and $.5 million for
                      the years ended December 31, 2013
                      and 2012, respectively.


    (4)               Represents the elimination of inter-
                      segment transactions and earnings
                      (losses), net from our former U.S.
                      unconsolidated oil and gas joint
                      venture, accounted for using the
                      equity method of ($301.8) million
                      for the year ended December 31,
                      2012.  In December 2012, we sold our
                      equity interest in the oil and gas
                      joint venture.


    (5)               Adjusted EBITDA is computed by
                      subtracting the sum of direct costs,
                      general and administrative expenses,
                      earnings (losses) from our former
                      U.S. oil and gas joint venture from
                      the sum of Operating revenues and
                      Earnings (losses) from
                      unconsolidated affiliates. There are
                      limitations inherent in using
                      adjusted EBITDA as a measure of
                      overall profitability because it
                      excludes significant expense items.
                      However, management evaluates the
                      performance of our business units
                      and the consolidated company based
                      on several criteria, including
                      adjusted EBITDA and adjusted income
                      (loss) derived from operating
                      activities, because we believe that
                      these financial measures accurately
                      reflect our ongoing profitability.
                      These amounts should not be used as
                      a substitute for the amounts
                      reported in accordance with GAAP. To
                      compensate for the limitations in
                      utilizing adjusted EBITDA as an
                      operating measure, management also
                      uses GAAP measures of performance,
                      including income from continuing
                      operations and net income, to
                      evaluate performance, but only with
                      respect to the Company as a whole
                      and not on a segment basis.  A
                      reconciliation of this non-GAAP
                      measure to income (loss) from
                      continuing operations before income
                      taxes, which is a GAAP measure, is
                      provided in the table set forth

    (6)               Represents the elimination of inter-
                      segment transactions and unallocated
                      corporate expenses.


    (7)               Adjusted income (loss) derived from
                      operating activities is computed by
                      subtracting the sum of direct costs,
                      general and administrative expenses,
                      depreciation and amortization and
                      earnings (losses) from our former
                      U.S. oil and gas joint venture from
                      the sum of Operating revenues and
                      Earnings (losses) from
                      unconsolidated affiliates. These
                      amounts should not be used as a
                      substitute for the amounts reported
                      in accordance with GAAP. However,
                      management evaluates the performance
                      of our business units and the
                      consolidated company based on
                      several criteria, including adjusted
                      income (loss) derived from operating
                      activities, because it believes that

    (8)               Excludes well-servicing rigs, which
                      are measured in rig hours.  Includes
                      our equivalent percentage ownership
                      of rigs owned by unconsolidated
                      affiliates.  Rig years represent a
                      measure of the number of equivalent
                      rigs operating during a given
                      period.  For example, one rig
                      operating 182.5 days during a 365-
                      day period represents 0.5 rig years.

    (10)              Rig hours represents the number of

    For all periods presented, the
     computation of diluted
     earnings (losses) per share
     excluded outstanding stock
     options and warrants with
     exercise prices greater than
     the average market price of
     Nabors' common shares because
     their inclusion would have
     been anti-dilutive and
     because they were not
     considered participating
     securities. The average number
     of options and warrants that
     were excluded from diluted
     earnings (losses) per share
     that would have potentially
     diluted earnings (losses) per
     share were 10,908,160 and
     15,000,882 shares during the
     three months ended December
     31, 2013 and 2012,
     respectively; 18,786,837
     shares during the three months
     ended September 30, 2013; and
     11,642,417 and 14,200,915
     shares during the years ended
     December 31, 2013 and 2012,
     respectively. In any period
     during which the average
     market price of Nabors' common
     shares exceeds the exercise
     prices of these stock options
     and warrants, such stock
     options and warrants are
     included in our diluted
     earnings (losses) per share
     computation using the if-
     converted method of
     accounting.  Restricted stock
     is included in our basic and
     diluted earnings (losses) per
     share computation using the
     two-class method of
     accounting in all periods
     because such stock is
     considered a participating
     security.
