Management Overview and Recent Developments in Market Conditions - We are a
Houston, Texas-based oilfield services company that primarily owns and operates
one of the largest fleets of land-based drilling rigs in the United States and a
large fleet of pressure pumping equipment.

Our contract drilling business operates in the continental United States and
internationally in Colombia and, from time to time, we pursue contract drilling
opportunities in other select markets. Our pressure pumping business operates
primarily in Texas and the Appalachian region. We also provide a comprehensive
suite of directional drilling services in most major producing onshore oil and
gas basins in the United States, and we provide services that improve the
statistical accuracy of directional and horizontal wellbores. We have other
operations through which we provide oilfield rental tools in select markets in
the United States. We also service equipment for drilling contractors, and we
provide electrical controls and automation to the energy, marine and mining
industries, in North America and other select markets. In addition, we own and
invest, as a non-operating working interest owner, in oil and natural gas assets
that are primarily located in Texas and New Mexico.

Crude oil prices and demand for drilling and completions equipment and services
increased in 2022, and industry supply of Tier-1, super-spec rigs remains
constrained. We currently expect our average rig count to be down two to three
rigs in the second quarter as activity transitions more to oil from natural gas.
The current demand for equipment and services remains dependent on macro
conditions, including commodity prices, geopolitical environment, inflationary
pressures, economic conditions in the United States and elsewhere and continued
focus by exploration and production companies and service companies on capital
discipline. Oil prices averaged $76.08 per barrel in the first quarter of 2023,
as compared to $82.79 per barrel in the fourth quarter of 2022. Natural gas
prices (based on the Henry Hub Spot Market Price) averaged $2.65 per MMBtu in
the first quarter of 2023 as compared to an average of $5.55 per MMBtu in the
fourth quarter of 2022.
Our average active rig count in the United States for the first quarter of 2023
was 131 rigs, consistent with the fourth quarter of 2022. Based on contracts in
place in the United States as of April 26, 2023, we expect an average of 79 rigs
operating under term contracts during the second quarter of 2023 and an average
of 53 rigs operating under term contracts during the four quarters ending March
31, 2024.

Our average active spread count was 12 spreads in the first quarter, consistent
with the fourth quarter of 2022. We calculated average active spreads as the
average number of spreads that were crewed and actively marketed during the
period. We expect to end the second quarter with 12 active pressure pumping
spreads.

With the recent slowdown in market activity, we have lowered our 2023 capital
expenditure forecast from $550 million to $510 million, including approximately
$30 million of customer-funded rig upgrades.

Recent Developments in Financial Matters - On November 9, 2022, we entered into
Amendment No. 3 to Amended and Restated Credit Agreement ("Amendment No. 3"),
which amended our amended and restated credit agreement, dated as of March 27,
2018 (as amended, the "Credit Agreement"), among us, as borrower, Wells Fargo
Bank, National Association, as administrative agent, letter of credit issuer,
swing line lender and lender and each of the other letter of credit issuers and
lenders party thereto.

Amendment No. 3, among other things, (i) revised the capacity under the letter
of credit facility to $100 million; (ii) revised the capacity under the swing
line facility to the lesser of $50 million and the amount of the swing line
provider's unused commitment; (iii) changed the LIBOR reference rate to a SOFR
reference rate; and (iv) extended the maturity date for $416.7 million of
revolving credit commitments of certain lenders under the Credit Agreement from
March 27, 2025 to March 27, 2026. As a result, of the $600 million of revolving
credit commitments under the Credit Agreement, the maturity date for $416.7
million of such commitments is March 27, 2026; the maturity date for $133.3
million of such commitments is March 27, 2025; and the maturity date for the
remaining $50 million of such commitments is March 27, 2024.

As of March 31, 2023, we had no borrowings outstanding under our revolving credit facility. We had no letters of credit outstanding under the Credit Agreement at March 31, 2023 and, as a result, had available borrowing capacity of $600 million at that date.



During the fourth quarter of 2022, we elected to repurchase portions of our
3.95% Senior Notes due 2028 (the "2028 Notes") and our 5.15% Senior Notes due
2029 (the "2029 Notes") in the open market. The principal amounts retired
through these transactions totaled $21.0 million of our 2028 Notes and $1.4
million of our 2029 Notes, plus accrued interest. We recorded corresponding
gains on the extinguishment of these amounts totaling $2.3 million and $0.1
million, respectively, net of the proportional write-off of associated deferred
financing costs and original issuance discounts.

During the first quarter of 2023, we elected to repurchase portions of our 2028
Notes and 2029 Notes in the open market. The principal amounts retired through
these transactions totaled $6.0 million of our 2028 Notes and $3.0 million of
our 2029 Notes, plus accrued interest. We recorded corresponding gains on the
extinguishment of these amounts totaling $0.8 million and $0.3 million,
respectively, net of the proportional write-off of associated deferred financing
costs and original issuance discounts. These gains are included in "Interest
expense, net of amount capitalized" in our unaudited condensed consolidated
statements of operations.

Impact on our Business from Oil and Natural Gas Prices and Other Factors - Our
revenues, profitability and cash flows are highly dependent upon prevailing
prices for oil and natural gas and upon our customers' ability to access capital
to fund their operating and capital expenditures. During periods of improved oil
and natural gas prices, the capital spending budgets of oil and natural gas
operators tend to expand, which generally results in increased demand for our
services. Conversely, in periods when oil and natural gas prices are relatively
low or when our customers have a reduced ability to access capital, the demand
for our services generally weakens, and we experience downward pressure on
pricing for our services. Even during periods of historically moderate or high
prices for oil and natural gas, companies exploring for oil and natural gas may
cancel or curtail programs or reduce their levels of capital expenditures for
exploration and production for a variety of reasons, which could reduce demand
for our services. We may also be impacted by delayed customer payments and
payment defaults associated with customer liquidity issues and bankruptcies.

The North American oil and natural gas services industry is cyclical and at
times experiences downturns in demand. During these periods, there has been
substantially more oil and natural gas service equipment available than
necessary to meet demand. As a result, oil and natural gas service contractors
have had difficulty sustaining profit margins and, at times, have incurred
losses during the downturn periods. We cannot predict either the future level of
demand for our oil and natural gas services or future conditions in the oil and
natural gas service businesses.

In addition to the dependence on oil and natural gas prices and demand for our
services, we are highly impacted by operational risks, competition, labor
issues, weather, the availability, from time to time, of products used in our
pressure pumping business, supplier delays and various other factors that could
materially adversely affect our business, financial condition, cash flows and
results of operations. Please see Item 1A of our Annual Report on Form 10-K for
the fiscal year ended December 31, 2022.

For the three months ended March 31, 2023 and December 31, 2022, our operating revenues consisted of the following (dollars in thousands):

Contract Drilling

We have addressed our customers' needs for drilling horizontal wells in shale
and other unconventional resource plays by improving the capabilities of our
drilling fleet. The U.S. land rig industry has in recent years referred to
certain high specification rigs as "super-spec" rigs, which we consider to be at
least a 1,500 horsepower, AC-powered rig that has at least a 750,000-pound
hookload, a 7,500-psi circulating system, and is pad-capable. Due to evolving
customer preferences, we refer to certain premium rigs as "Tier-1, super spec"
rigs, which we consider as being a super-spec rig that also has a third mud pump
and raised drawworks that allow for more clearance underneath the rig floor. As
of March 31, 2023, our rig fleet included 172 super-spec rigs, of which 120 were
Tier-1, super-spec rigs.

We maintain a backlog of commitments for contract drilling services under term
contracts, which we define as contracts with a duration of six months or more.
Our contract drilling backlog in the United States as of March 31, 2023 was
approximately $890 million. Approximately 26% of the total contract drilling
backlog in the United States at March 31, 2023 is reasonably expected to remain
at March 31, 2024. See Note 2 of Notes to unaudited condensed consolidated
financial statements for additional information on backlog.

Pressure Pumping


                                       23
--------------------------------------------------------------------------------

As of March 31, 2023, we had approximately 1.2 million horsepower in our
pressure pumping fleet. We provide pressure pumping services to oil and natural
gas operators primarily in Texas and the Appalachian region. Substantially all
of the revenue in the pressure pumping segment is from well stimulation
services, such as hydraulic fracturing, for completion of new wells and remedial
work on existing wells. We also provide cementing services through the pressure
pumping segment.

Directional Drilling

We provide a comprehensive suite of directional drilling services in most major
producing onshore oil and gas basins in the United States. Our directional
drilling services include directional drilling, measurement-while-drilling and
supply and rental of downhole performance motors. We also provide services that
improve the statistical accuracy of directional and horizontal wellbores.

Other Operations



Our oilfield rentals business, with a fleet of premium oilfield rental tools,
along with the results of our ownership, as a non-operating working interest
owner, in oil and gas assets located in Texas and New Mexico, provide the
largest revenue contributions to our other operations. Other operations also
includes the results of our electrical controls and automation business and the
results of our drilling equipment service business.

(1)

Adjusted gross margin is defined as revenues less direct operating costs (excluding depreciation, amortization and impairment expense). See Non-GAAP Financial Measures below for a reconciliation of GAAP gross margin to adjusted gross margin by segment.

(2)

A rig is considered to be operating if it is earning revenue pursuant to a contract on a given day. Average rigs operating is defined as operating days divided by the number of days in the period.

(3)

Average adjusted gross margin per operating day is defined as adjusted gross margin divided by operating days.

Generally, the revenues in our contract drilling segment are most impacted by two primary factors: our average number of rigs operating and our average revenue per operating day. Our average revenue per operating day is largely dependent on the pricing terms of our rig contracts. Revenues increased primarily due to improved pricing.



The decrease in capital expenditures was primarily due to the timing of order
placement and spending on committed deliveries that more heavily impacted the
fourth quarter of 2022.

(3)

Average adjusted gross margin per total job is defined as adjusted gross margin divided by total jobs. Adjusted gross margin as a percentage of revenues is defined as adjusted gross margin divided by revenues.



Generally, the revenues in our pressure pumping segment are most impacted by the
number and design of fracturing jobs (including whether or not we provide
proppant and other materials). Direct operating costs are also most impacted by
these same factors. Our average revenue per fracturing job is largely dependent
on the pricing terms of our pressure pumping contracts and the design of the
jobs.

Revenues decreased primarily due to lower utilization.

(1)

Adjusted gross margin is defined as revenues less direct operating costs (excluding depreciation, amortization and impairment expense). See Non-GAAP Financial Measures below for a reconciliation of GAAP gross margin to adjusted gross margin by segment.

Revenue decreased due to decreased job activity. We averaged 41 jobs per day during the three months ended March 31, 2023 as compared to 44 jobs per day during the three months ended December 31, 2022.

The increase in capital expenditures was primarily due the purchase of rotary steerable system tools and the timing of order placement that more heavily impacted the first quarter of 2023.

(1)
Adjusted gross margin is defined as revenues less direct operating costs
(excluding depreciation, depletion, amortization and impairment expense). See
Non-GAAP Financial Measures below for a reconciliation of GAAP gross margin to
adjusted gross margin by segment.

Other operations revenue increased primarily due to a $1.6 million increase in
our oilfield rentals business revenues, which was offset by a $1.0 million
decline in oil and natural gas revenues primarily as a result of lower crude oil
and natural gas market prices. The average WTI-Cushing price for the first
quarter of 2023 was $76.08 per barrel as compared to $82.79 per barrel in the
fourth quarter of 2022. Natural gas prices (based on the Henry Hub Spot Market
Price) averaged $2.65 per MMBtu in the first quarter of 2023 as compared to
$5.55 per MMBtu in the fourth quarter of 2022.

Depreciation, depletion, amortization and impairment increased primarily due to
a $2.0 million impairment in our oil and natural gas business recorded in the
first quarter of 2023 as compared to a $0.8 million impairment recorded in the
fourth quarter of 2022.

Selling, general and administrative expense decreased primarily due to the fair
value remeasurements of the phantom unit awards. See Note 10 of Notes to
unaudited condensed consolidated financial statements for additional information
on phantom unit awards.

Other operating (income) expenses, net includes net losses associated with the
disposal of assets. Accordingly, the related gains or losses have been excluded
from the results of specific segments. Other operating (income) expenses, net
increased due to a $6.5 million reversal of cumulative compensation costs
associated with certain performance-based restricted stock units.

The $2.1 million change in other income (expense) was primarily due to foreign currency adjustments related to our Colombian operations.

Income Taxes



Our effective income tax rate fluctuates from the U.S. statutory tax rate based
on, among other factors, changes in pretax income in jurisdictions with varying
statutory tax rates, the impact of U.S. state and local taxes, the realizability
of deferred tax assets and other differences related to the recognition of
income and expense between GAAP and tax accounting.

                                       26
--------------------------------------------------------------------------------

Our effective income tax rate for the three months ended March 31, 2023 was
16.8%, compared with 7.7% for the three months ended December 31, 2022. The
change in our effective income tax rate for the three months ended March 31,
2023 compared to December 31, 2022, was primarily attributable to the impact of
valuation allowances on deferred tax assets.
In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will not be realized, and when necessary, valuation allowances are
provided. The ultimate realization of deferred tax assets is dependent upon the
generation of future taxable income during the periods in which those temporary
differences become deductible. We assess the realizability of our deferred tax
assets quarterly and consider carryback availability, the scheduled reversal of
deferred tax liabilities, projected future taxable income and tax planning
strategies in making this assessment. In the first quarter of 2023, the
effective tax rate takes into consideration the estimated valuation allowance
based on forecasted 2023 income.
We continue to monitor income tax developments in the United States and other
countries where we have legal entities. We will incorporate into our future
financial statements the impacts, if any, of future regulations and additional
authoritative guidance when finalized.


Liquidity and Capital Resources



Our primary sources of liquidity are cash and cash equivalents, availability
under our revolving credit facility and cash provided by operating activities.
As of March 31, 2023, we had approximately $293 million in working capital,
including $157 million of cash and cash equivalents, and $600 million available
under our revolving credit facility.

Our Credit Agreement is a committed senior unsecured revolving credit facility
that permits aggregate borrowings of up to $600 million, including a letter of
credit facility that, at any time outstanding, is limited to $100 million and a
swing line facility that, at any time outstanding, is limited to the lesser of
$50 million and the amount of the swing line provider's unused commitment. As of
March 31, 2023, we had no borrowings outstanding under our revolving credit
facility, and no letters of credit outstanding under the Credit Agreement and,
as a result, had available borrowing capacity of approximately $600 million at
that date. Of the revolving credit commitments, $50 million expires on March 27,
2024, $133.3 million expires on March 27, 2025, and the remaining $416.7 million
expires on March 27, 2026. Subject to customary conditions, we may request that
the lenders' aggregate commitments be increased by up to $300 million, not to
exceed total commitments of $900 million. Additionally, we have the option,
subject to certain conditions, to exercise one one-year extension of the
maturity date.

Loans under the Credit Agreement bear interest by reference, at our election, to
the SOFR rate or base rate, as described in "Item 3" below. If our credit rating
is below investment grade at both Moody's and S&P, we will become subject to a
restricted payment covenant. The Credit Agreement also contains a financial
covenant that requires our total debt to capitalization ratio, expressed as a
percentage, not exceed 50%.

We also have a Reimbursement Agreement (the "Reimbursement Agreement") with The
Bank of Nova Scotia ("Scotiabank"), pursuant to which we may from time to time
request that Scotiabank issue an unspecified amount of letters of credit. Under
the terms of the Reimbursement Agreement, we will reimburse Scotiabank on demand
for any amounts that Scotiabank has disbursed under any letters of credit. Fees,
charges and other reasonable expenses for the issuance of letters of credit are
payable by us at the time of issuance at such rates and amounts as are in
accordance with Scotiabank's prevailing practice. We are obligated to pay to
Scotiabank interest on all amounts not paid by us on the date of demand or when
otherwise due at the LIBOR rate plus 2.25% per annum. A letter of credit fee is
payable by us equal to 1.50% times the amount of outstanding letters of credit.

We had $65.0 million of outstanding letters of credit at March 31, 2023, which
was comprised of $65.0 million outstanding under the Reimbursement Agreement and
no amounts outstanding under the Credit Agreement. We maintain these letters of
credit primarily for the benefit of various insurance companies as collateral
for retrospective premiums and retained losses which could become payable under
terms of the underlying insurance contracts. These letters of credit expire
annually at various times during the year and are typically renewed. As of March
31, 2023, no amounts had been drawn under the letters of credit.

Our outstanding long-term debt at March 31, 2023 was $827 million and consisted
of $482 million of our 2028 Notes and $345 million of our 2029 Notes. We were in
compliance with all covenants under the associated indentures at March 31, 2023.

For a full description of the Credit Agreement, the Reimbursement Agreement, the
2028 Notes and the 2029 Notes, please see Note 7 of Notes to unaudited condensed
consolidated financial statements.

Cash Requirements



We believe our current liquidity, together with cash expected to be generated
from operations, should provide us with sufficient ability to fund our current
plans to maintain and make improvements to our existing equipment, service our
debt and pay cash dividends for at least the next 12 months.

If we pursue opportunities for growth that require capital, we believe we would
be able to satisfy these needs through a combination of working capital, cash
flows from operating activities, borrowing capacity under our revolving credit
facility or additional debt or equity financing. However, there can be no
assurance that such capital will be available on reasonable terms, if at all.

A portion of our capital expenditures can be adjusted and managed by us to match
market demand and activity levels. With the recent slowdown in market activity,
we have lowered our 2023 capital expenditure forecast from $550 million to $510
million, including approximately $30 million of customer-funded rig upgrades.

The majority of these expenditures are expected to be used for normal, recurring items necessary to support our business.

During the three months ended March 31, 2023, our sources of cash flow included:

$234 million from operating activities, and

$1.3 million in proceeds from the disposal of property and equipment.

During the three months ended March 31, 2023, our uses of cash flow included:

$118 million to make capital expenditures for the betterment and refurbishment
of drilling and pressure pumping equipment and, to a much lesser extent,
equipment for our other businesses, to acquire and procure equipment to support
our contract drilling, pressure pumping, directional drilling, oilfield rentals
and manufacturing operations, and to fund investments in oil and natural gas
properties on a non-operating working interest basis,

$73.6 million for repurchases of our common stock,

$16.9 million to pay dividends on our common stock,

$5.2 million for repurchases of our 2028 Notes, and

$2.6 million for repurchases of our 2029 Notes.

We paid cash dividends during the three months ended March 31, 2023 as follows:



                        Per Share           Total
                                       (in thousands)
Paid on March 16, 2023 $      0.08     $        16,916



On April 26, 2023, our Board of Directors approved a cash dividend on our common
stock in the amount of $0.08 per share to be paid on June 15, 2023 to holders of
record as of June 1, 2023. The amount and timing of all future dividend
payments, if any, are subject to the discretion of the Board of Directors and
will depend upon business conditions, results of operations, financial
condition, terms of our debt agreements and other factors. Our Board of
Directors may, without advance notice, reduce or suspend our dividend in order
to improve our financial flexibility and position our company for long-term
success. There can be no assurance that we will pay a dividend in the future.

We may, at any time and from time to time, seek to retire or purchase our
outstanding debt for cash through open-market purchases, privately negotiated
transactions, redemptions or otherwise. Such repurchases, if any, will be upon
such terms and at such prices as we may determine, and will depend on prevailing
market conditions, our liquidity requirements, contractual restrictions and
other factors. The amounts involved may be material.

In September 2013, our Board of Directors approved a stock buyback program. In
October 2022, our Board of Directors approved an increase of the authorization
under the stock buyback program to allow for an aggregate of $300 million of
future share repurchases. All purchases executed to date have been through open
market transactions. Purchases under the buyback program are made at
management's discretion, at prevailing prices, subject to market conditions and
other factors. Purchases may be made at any time without prior notice. There is
no expiration date associated with the buyback program. As of March 31, 2023, we
had remaining authorization to purchase approximately $169 million of our
outstanding common stock under the stock buyback program. Shares of

                                       28
--------------------------------------------------------------------------------

stock purchased under the buyback program are held as treasury shares. On April
26, 2023, our Board of Directors approved another increase of the authorization
under the stock buyback program to allow for an aggregate of $300 million of
future share repurchases.

Treasury stock acquisitions during the three months ended March 31, 2023 were as follows (dollars in thousands):



                                               Shares           Cost

Treasury shares at beginning of period 88,758,722 $ 1,453,079 Purchases pursuant to stock buyback program 5,629,117 74,307 Treasury shares at end of period

              94,387,839     $ 1,527,386



Commitments - As of March 31, 2023, we had commitments to purchase major
equipment totaling approximately $129 million for our drilling, pressure
pumping, directional drilling and oilfield rentals businesses. Our pressure
pumping business has entered into agreements to purchase minimum quantities of
proppants and chemicals from certain vendors. As of March 31, 2023, the
remaining minimum obligation under these agreements was approximately $17.5
million, of which approximately $14.5 million and $3.0 million relate to the
remainder of 2023 and 2024, respectively.

See Note 8 of Notes to unaudited condensed consolidated financial statements for
additional information on our current commitments and contingencies as of March
31, 2023.

Operating lease liabilities totaled $23.4 million at March 31, 2023. There have
been no material changes to our operating lease liabilities since December 31,
2022.

Trading and Investing - We have not engaged in trading activities that include
high-risk securities, such as derivatives and non-exchange traded contracts. We
invest cash primarily in highly liquid, short-term investments such as overnight
deposits and money market accounts.


Non-GAAP Financial Measures

Adjusted EBITDA

Adjusted earnings before interest, taxes, depreciation and amortization
("Adjusted EBITDA") is not defined by accounting principles generally accepted
in the United States of America ("GAAP"). We define Adjusted EBITDA as net
income plus income tax expense, net interest expense, and depreciation,
depletion, amortization and impairment expense. We present Adjusted EBITDA as a
supplemental disclosure because we believe it provides to both management and
investors additional information with respect to the performance of our
fundamental business activities and a comparison of the results of our
operations from period to period and against our peers without regard to our
financing methods or capital structure. We exclude the items listed above from
net income in arriving at Adjusted EBITDA because these amounts can vary
substantially from company to company within our industry depending upon
accounting methods and book values of assets, capital structures and the method
by which the assets were acquired. Adjusted EBITDA should not be construed as an
alternative to the GAAP measure of net income. Our computations of Adjusted
EBITDA may not be the same as similarly titled measures of other companies. Set
forth below is a reconciliation of the non-GAAP financial measure of Adjusted
EBITDA to the GAAP financial measure of net income.

Critical Accounting Estimates

Our consolidated financial statements are impacted by certain estimates and
assumptions made by management. A detailed discussion of our critical accounting
estimates is included in our Annual Report on Form 10-K for the fiscal year
ended December 31, 2022. There have been no material changes in these critical
accounting estimates.

Recently Issued Accounting Standards

See Note 1 of Notes to unaudited condensed consolidated financial statements for a discussion of the impact of recently issued accounting standards.

Volatility of Oil and Natural Gas Prices and its Impact on Operations and Financial Condition



Our revenue, profitability and cash flows are highly dependent upon prevailing
prices for oil and natural gas and expectations about future prices. Crude oil
prices and demand for drilling and completions equipment and services increased
in 2022, and industry supply of Tier-1, super-spec rigs remains constrained. We
currently expect our average rig count to be down two to three rigs in the
second quarter as activity transitions more to oil from natural gas. The current
demand for equipment and services remains dependent on macro conditions,
including commodity prices, geopolitical environment, inflationary pressures,
economic conditions in the United States and elsewhere and continued focus by
exploration and production companies and service companies on capital
discipline. Oil prices averaged $76.08 per barrel in the first quarter of 2023,
as compared to $82.79 per barrel in the fourth quarter of 2022. Natural gas
prices (based on the Henry Hub Spot Market Price) averaged $2.65 per MMBtu in
the first quarter of 2023 as compared to an average of $5.55 per MMBtu in the
fourth quarter of 2022.

In light of these and other factors, we expect oil and natural gas prices to
continue to be volatile and to affect our financial condition, operations and
ability to access sources of capital. Higher oil and natural gas prices do not
necessarily result in increased activity because demand for our services is
generally driven by our customers' expectations of future oil and natural gas
prices, as well as our customers' ability to access sources of capital to fund
their operating and capital expenditures. A decline in demand for oil and
natural gas, prolonged low oil or natural gas prices, expectations of decreases
in oil and natural gas prices or a reduction in the ability of our customers to
access capital would likely result in reduced capital expenditures by our
customers and decreased demand for our services, which could have a material
adverse effect on our operating results, financial condition and cash flows.
Even during periods of historically moderate or high prices for oil and natural
gas, companies exploring for oil and natural gas may cancel or curtail programs

                                       30
--------------------------------------------------------------------------------

or reduce their levels of capital expenditures for exploration and production for a variety of reasons, which could reduce demand for our services.
