1. ORGANIZATION AND PRINCIPLES OF CONSOLIDATION

Dril-Quip, Inc., a Delaware corporation (the “Company” or “Dril-Quip”), manufactures highly engineered offshore drilling and production equipment which is well suited for use in deepwater, harsh environment and severe service applications. The Company’s principal products consist of subsea and surface wellheads, subsea and surface production trees, mudline hanger systems, specialty connectors and associated pipe, drilling and production riser systems, wellhead connectors and diverters for use by major integrated, large independent and foreign national oil and gas companies in offshore areas throughout the world. Dril-Quip also provides installation and reconditioning services and rents running tools for use in connection with the installation and retrieval of its products.

The Company’s operations are organized into three geographic segments—Western Hemisphere (including North and South America; headquartered in Houston, Texas), Eastern Hemisphere (including Europe and Africa; headquartered in Aberdeen, Scotland) and Asia-Pacific (including the Pacific Rim, Southeast Asia, Australia, India and the Middle East; headquartered in Singapore). Each of these segments sells similar products and services and the Company has major manufacturing facilities in all three of its headquarter locations. The Company previously reported a single industry segment and disclosed certain geographic financial information. All prior periods presented herein have been revised to present geographic segment information. See note 4.

The condensed consolidated financial statements included herein have been prepared by Dril-Quip and are unaudited, except for the balance sheet at December 31, 2004, which has been derived from the audited financial statements at that date. In the opinion of management, the unaudited condensed consolidated interim financial statements include all adjustments, consisting solely of normal recurring adjustments, necessary for a fair presentation of the financial position as of March 31,June 30, 2005, and the results of operations for each of the three and six-month periods ended June 30, 2005 and 2004 and the cash flows for each of the three-monthsix-month periods ended March 31,June 30, 2005 and 2004. Although management believes the unaudited interim related disclosures in these financial statements are adequate to make the information presented not misleading, certain information and footnote disclosures normally included in annual audited financial statements prepared in accordance with generally accepted accounting principles in the United States have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The results of operations and the cash flows for the three-monthsix-month period ended March 31,June 30, 2005 are not necessarily indicative of the results to be expected for the full year. The consolidated financial statements included herein should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004.

2. SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All material intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

DRIL-QUIP, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(UNAUDITED)

Some of the Company’s more significant estimates are those affected by critical accounting policies for revenue recognition, inventories and contingent liabilities as discussed more fully in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004.

Cash and cash equivalents

Investments that have a maturity of three months or less from the date of purchase are classified as cash equivalents.

Inventories

Inventory costs are determined principally by the use of the first-in, first-out (FIFO) method, and are stated at the lower of cost or market. Inventory is valued principally using standard costs that are calculated based upon direct costs incurred and overhead allocations. Periodically, obsolescence reviews are performed on slow-moving inventories and reserves are established based on current assessments about future demands and market conditions. The inventory values have been reduced by a reserve for excess and obsolete inventories. Inventory reserves of $9.8$10.0 million and $8.4$8.9 million were recorded as of March 31,June 30, 2005 and 2004, respectively. If market conditions are less favorable than those projected by management, additional inventory reserves may be required.

Property, Plant, and Equipment

Property, plant, and equipment are carried at cost, with depreciation provided on a straight-line basis over their estimated useful lives.

Income Taxes

The Company accounts for income taxes using the liability method. Deferred income taxes are provided on income and expenses which are reported in different periods for income tax and financial reporting purposes.

Revenue Recognition

The Company delivers most of its products and services on an as-needed basis by its customers and records revenues as the products are shipped and as services are rendered. Allowances for doubtful accounts are determined generally on a case by case basis. Certain revenues are derived from long-term product contracts which generally require more than one year to fulfill. Revenues and profits on long-term product contracts are recognized under the percentage-of-completion method based on a cost-incurred basis. Losses, if any, on contracts are recognized when they become known. Contracts for long-term projects contain provisions for customer progress payments. Payments in excess of revenues recognized are included as a customer prepayment liability.

Foreign Currency

The financial statements of foreign subsidiaries are translated into U.S. dollars at current exchange rates except for revenues and expenses, which are translated at average rates during each reporting period. Translation adjustments are reflected as a separate component of stockholders’ equity and have no current effect on earnings or cash flows.

Foreign currency exchange transactions are recorded using the exchange rate at the date of the settlement. These amounts are included in selling, general and administrative costs in the consolidated statements of income.

Stock-Based Compensation

The Company has adopted the disclosure-only provisions of Statement of Financial Accounting Standards (SFAS) No. 123, “Accounting For Stock Based Compensation” (“SFAS No. 123”). Accordingly, no compensation cost has been recognized for stock options granted under the Company’s incentive plan.

Under SFAS No. 123, pro forma information is required to reflect the estimated effect on net income and earnings per share as if the Company had accounted for the stock options using the fair value method. The fair value was estimated at the date of grant using a Black-Scholes option pricing model with the following assumptions:

Had compensation cost for the Company’s stock-based compensation plans been determined based on the fair value at the grant dates for awards consistent with the method available under SFAS No. 123, the Company’s net income and earnings per share for each of the three monthsand six month periods ended March 31,June 30, 2004, and 2005 would have been reduced to the pro forma amounts listed below.

There were no option grants during the first quarter ofsix months ended June 30, 2005.

Fair Value of Financial Instruments

The Company’s financial instruments consist primarily of cash and cash equivalents, receivables, payables and debt instruments. The carrying values of these financial instruments approximate their respective fair values as they are either short-term in nature or carry interest rates which approximate market rates.

Concentration of Credit Risk

Financial instruments which subject the Company to concentrations of credit risk consist principally of trade receivables. The Company grants credit to its customers, which operate primarily in the oil and gas industry. The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. The Company maintains reserves for potential credit losses and such losses have historically been within management’s expectations.

Comprehensive Income.Income

SFAS No. 130 establishes the rules for the reporting and display of comprehensive income and its components. SFAS No. 130 requires the Company to include unrealized gains or losses on foreign currency translation adjustments in other comprehensive income. Generally, gains are attributed to a weakening U.S. dollar and losses are the result of a strengthening U.S. dollar.

The following table provides comprehensive income for the periods indicated:

Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed considering the dilutive effect of stock options.

The net income used in the basic and dilutive earningsearning per share calculations is the same. The following table reconciles the number of common shares outstanding at March 31June 30 of each year to the weighted average of common shares outstanding and the weighted average number of common and dilutive potential common shares outstanding for the purpose of calculating basic and diluted earnings per common share:

New Accounting Standards

In December 2004, the FASB issued Statement of Financial Accounting Standard (“SFAS”) No. 123R,Share-Based Payments. This statement is a revision of SFAS Statement No. 123,Accounting for Stock-Based Compensation and supersedes APB Opinion No. 25,Accounting for Stock Issued to Employees, and its related implementation guidance. SFAS No. 123R addresses all forms of share based payment (“SBP”) awards including shares issued under employee stock purchase plans, stock options, restricted stock and stock appreciation rights. Under SFAS No. 123R, SBP awards result in a cost that will be measured at fair value on the awards’ grant date, based on the estimated number of awards that are expected to vest and will be reflected as compensation expense in the financial statements. In addition, this statement will apply to unvested options granted prior to the effective date.

This new standard is currently effective at the beginning of the next fiscal year that begins after December 15, 2005. Dril-Quip, Inc. is currently evaluating the effect that implementation of the new standard will have on its financial position, results of operationoperations and cash flows.

The following is management’s discussion and analysis of certain significant factors that have affected certain aspects of the Company’s financial position and results of operations during the periods included in the accompanying unaudited condensed consolidated financial statements. This discussion should be read in conjunction with the unaudited condensed consolidated financial statements included elsewhere herein, and with the discussion under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the annual consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004.

Overview

Dril-Quip manufactures highly engineered offshore drilling and production equipment which is well suited for use in deepwater, harsh environment and severe service applications. The Company designs and manufactures subsea equipment, surface equipment and offshore rig equipment for use by major integrated, large independent and foreign national oil and gas companies in offshore areas throughout the world. The Company’s principal products consist of subsea and surface wellheads, subsea and surface production trees, mudline hanger systems, specialty connectors and associated pipe, drilling and production riser systems, wellhead connectors and diverters. Dril-Quip also provides installation and reconditioning services and rents running tools for use in connection with the installation and retrieval of its products.

Both the market for offshore drilling and production equipment and services and the Company’s business are substantially dependent on the condition of the oil and gas industry and, in particular, the willingness of oil and gas companies to make capital expenditures on exploration, drilling and production operations offshore. Oil and gas prices and the level of offshore drilling and production activity have historically been characterized by significant volatility.

Revenues.Dril-Quip’s revenues are generated from two sources: products and services. Product revenues are derived from the sale of offshore drilling and production equipment, and service revenues are earned when the Company provides installation and reconditioning services as well as rental running tools for installation and retrieval of its products. For the threesix months ended March 31,June 30, 2005, the Company derived 84%85% of its revenues from the sale of its products and 16%15% of its revenues from services. Service revenues generally correlate to revenues from product sales because increased product sales generate increased revenues from installation services and rental running tools. Substantially all of Dril-Quip’s sales are made on a purchase order basis. Purchase orders are subject to change and/or termination at the option of the customer. In case of a change or termination, the customer is required to pay the Company for work performed and other costs necessarily incurred as a result of the change or termination.

The Company accounts for larger and more complex projects that have relatively longer manufacturing time frames on a percentage of completion basis. For the first threesix months of 2005, twofour projects representing approximately 11%18% of the Company’s revenues were accounted for using percentage of completion accounting. This percentage may fluctuate in the future. Revenues accounted for in this manner are generally recognized on the ratio of costs incurred to the total estimated costs. Accordingly, price and cost estimates are reviewed periodically as the work progresses and adjustments proportionate to the percentage of completion are reflected in the period when such estimates are revised. Losses, if any, are recognized when they become known. Amounts billed to or received from customers in excess of revenues recognized are classified as a current liability.

Foreign sales represent a significant portion of the Company’s business. In the threesix months ended March 31,June 30, 2005, the Company generated approximately 61%68% of its revenues from sales outside the United States. In this period, approximately 61%60% (on the basis of revenues generated) of all products sold were manufactured in the United States.

1011

Cost of Sales.The principal elements of cost of sales are labor, raw materials and manufacturing overhead. Variable costs, such as labor, raw materials, supplies and energy, generally account for approximately two-thirds of the Company’s cost of sales. Fixed costs, such as the fixed portion of manufacturing overhead, constitute the remainder of the Company’s cost of sales. Cost of sales as a percentage of revenues is also influenced by the product mix sold in any particular quarter and market conditions. The Company’s costs related to its foreign operations do not significantly differ from its domestic costs.

Selling, General and Administrative Expenses.Selling, general and administrative expenses include the costs associated with sales and marketing, general corporate overhead, compensation expense, legal expenses, foreign currency transaction gains and losses, and other related administrative functions.

Engineering and Product Development Expenses.Engineering and product development expenses consist of new product development and testing, as well as application engineering related to customized products.

Income Tax Provision.Dril-Quip’s effective tax rate has historically been lower than the statutory rate due to benefits from research and development expenditures, foreign sales and foreign income tax rate differentials.

Results of Operations

The following table sets forth, for the periods indicated, certain statement of operations data expressed as a percentage of revenues:

Three Months Ended March 31,June 30, 2005 Compared to Three Months Ended March 31,June 30, 2004.

Revenues. Revenues increased by $16.6$27.7 million, or approximately 31%52.3%, to $70.0$80.6 million in the three months ended March 31,June 30, 2005 from $53.4$52.9 million in the three months ended March 31,June 30, 2004. The net increase resulted primarily from increased product revenues in the Western Hemisphere, Asia PacificAsia-Pacific and the Eastern Hemisphere of $8.6$10.3 million, $5.1$11.5 million and $2.5$3.1 million, respectively. Service revenues increased by approximately $400,000 with increased service revenues in the Western Hemisphere, of $1.0 millionAsia-Pacific and decreased revenues in Asia Pacific of $300,000 and in the Eastern Hemisphere of $300,000.by approximately $1.7 million, $900,000 and $200,000, respectively. In general, the increase in revenues resulted from increased demand for the Company’s products realized on a worldwide basis as oil and gas companies have increased their levels of capital expenditures on exploration, drilling and production operations offshore.

Cost of Sales.Cost of sales increased $11.4by $19.2 million, or approximately 30%52.3%, to $48.9$55.8 million for the three months ended March 31,June 30, 2005 from $37.5$36.6 million for the same period in 2004. As a percentage of revenues, cost of sales were approximately 70%69% for each of the three-month periods ending March 31,June 30, 2005 and 2004.

1112

Selling, General and Administrative Expenses.For the three months ended March 31,June 30, 2005, selling, general and administrative expenses increased by approximately $2.1$1.3 million or approximately 28%15.8%, to $9.5 million from $7.4$8.2 million in the 2004 period. The increase in selling, general and administrative expenses was primarily due to increased labor and overhead expenses resulting from increased headcountstaffing levels in the areas of sales, administration and finance. In addition, theThe Company experienced approximately $300,000$570,000 in foreign currency transaction gains in the second quarter of 2005 versus approximately $20,000 in foreign currency transaction losses in the first quarter of 2005 versus approximately $200,000 in foreign currency transaction gains in the firstsecond quarter of 2004. Selling, general and administrative expenses as a percentage of revenues declined from 13.8%15.4% in 2004 to 13.6%11.7% in 2005.

Engineering and Product Development Expenses.For the three months ended March 31,June 30, 2005, engineering and product development expenses increased by $700,000$1.7 million or approximately 16%42.6% to $5.0$5.7 million from $4.3$4.0 million in the same period of 2004. This was primarily due to increased headcount and the corresponding increased salary expenses related to new product development. Engineering and product development expenses as a percentage of revenues declined from 8.0%7.5% in 2004 to 7.2%7.1% in 2005.

Interest Expense.Interest expense for the three months ended March 31,June 30, 2005 was $364,000$410,000 as compared to interest expense of $310,000$248,000 for the three-month period ended March 31,June 30, 2004. This change resulted primarily from higher interest rates and additional borrowing during the period ended March 31,June 30, 2005 under the Company’s unsecured revolving line of credit as compared to borrowings during the period ended March 31,June 30, 2004.

Net Income.Net income was approximately $4.3$6.7 million for the three months ended March 31,June 30, 2005 and $2.5$2.8 million for the same period in 2004, for the reasons set forth above.

Six Months Ended June 30, 2005 Compared to Six Months Ended June 30, 2004.

Revenues. Revenues increased by $44.3 million, or approximately 41.7%, to $150.6 million in the six months ended June 30, 2005 from $106.3 million in the six months ended June 30, 2004. The net increase resulted primarily from increased product revenues in the Western Hemisphere, Asia-Pacific and the Eastern Hemisphere of $19.0 million, $14.0 million and $8.2 million, respectively. Service revenues increased by approximately $3.1 million with increased service revenues in the Western Hemisphere of $2.7 million and in the Eastern Hemisphere of $500,000, offset by decreased revenues in Asia-Pacific of $100,000. In general, the increase in revenues resulted from increased demand for the Company’s products realized on a worldwide basis as oil and gas companies have increased their levels of capital expenditures on exploration, drilling and production operations offshore.

Cost of Sales.Cost of sales increased by $30.6 million, or approximately 41.3%, to $104.7 million for the six months ended June 30, 2005 from $74.1 million for the same period in 2004. As a percentage of revenues, cost of sales were approximately 70% for each of the six-month periods ending June 30, 2005 and 2004.

Selling, General and Administrative Expenses.For the six months ended June 30, 2005, selling, general and administrative expenses increased by approximately $3.4 million or 21.7%, to $19.0 million from $15.6 million in the 2004 period. The increase in selling, general and administrative expenses was primarily due to increased labor and overhead expenses resulting from increased staffing levels in the areas of sales, administration and finance. The Company experienced approximately $350,000 in foreign currency transaction gains during the six months ended June 30, 2005 versus approximately $320,000 in foreign currency transaction gains during the six months ended June 30, 2004. Selling, general and administrative expenses as a percentage of revenues declined from 14.7% in 2004 to 12.6% in 2005.

Engineering and Product Development Expenses.For the six months ended June 30, 2005, engineering and product development expenses increased by $2.4 million, or approximately 29.5% to $10.7 million from $8.3 million in the same period of 2004. This was primarily due to increased headcount and the corresponding increased salary expenses related to new product development. Engineering and product development expenses as a percentage of revenues declined from 7.8% in 2004 to 7.1% in 2005.

13

Interest Expense.Interest expense for the six months ended June 30, 2005 was $774,000 as compared to interest expense of $558,000 for the six-month period ended June 30, 2004. This change resulted primarily from higher interest rates and additional borrowing during the period ended June 30, 2005 under the Company’s unsecured revolving line of credit as compared to borrowings during the period ended June 30, 2004.

Net Income.Net income was approximately $11.0 million for the six months ended June 30, 2005 and $5.3 million for the same period in 2004, for the reasons set forth above.

Liquidity and Capital Resources

The primary liquidity needs of the Company are (i) to fund capital expenditures to improve and expand facilities and manufacture additional rental running tools and (ii) to fund working capital. The Company’s principal sources of funds are cash flows from operations and bank indebtedness.

Net cash provided by (used in) operating activities was approximately $2.2 million($700,000) and $9.8$20.0 million for the threesix months ended March 31,June 30, 2005 and 2004, respectively. The decline in cash flow from operating activities was principally due to increased working capital requirements attributable to inventory and trade receivables offset by net income, trade accounts payable and accrued expenses.

Net cash provided by financing activities in the first quarter of 2005 resulted from proceeds received from the Company’s revolving line of credit ($1.6 million) and proceeds received from the sale of stock related to the exercise of options awarded under the Company’s 1997 Incentive Plan ($3.7 million).

Capital expenditures by the Company were $4.7$8.8 million and $3.4$7.1 million for the threesix months ended March 31,June 30, 2005 and 2004, respectively. This increase was primarily due to expenditures for land and facilities at the Company’s wholly owned subsidiary in Macae, Brazil.Brazil and cost associated with running tools. Principal payments on long-termlong term debt were $482,000 and borrowing on the Company’s revolving line of credit were approximately $244,000 and $8.3was $8.6 million for the three months ended March 31,six month period ending June 30, 2005, compared to payments on long-term debt of $551,000 and 2004, respectively.payments of $13.0 million on the Company’s revolving line of credit for the same period in 2004.

The Company has a credit facility with Guaranty Bank, FSB providing an unsecured revolving line of credit of up to $65 million. At the option of the Company, borrowing under this facility bears interest at either a rate equal to LIBOR (London Interbank Offered Rate) plus 1.75%1.5% or the Guaranty Bank base rate. The facility calls for quarterly interest payments and terminates on May 18, 2006.June 1, 2009. The facility also contains certain covenants including maintaining minimum tangible net worth levels and not exceeding specified funded debt amounts and required interest coverage ratios.amounts. The Company is in compliance with all loan covenants. As of March 31,June 30, 2005, the Company had drawn down $25.5$32.5 million under this facility for operating activities and capital expenditures. It is the Company’s intent to refinance this facility prior to maturity.

Dril-Quip (Europe) Limited has a credit agreement with the Bank of Scotland dated March 21, 2001 in the original amount of U.K. Pounds Sterling 3.7 million (approximately U.S. $7.0$6.6 million). Borrowing under this facility bears interest at the Bank of Scotland base rate, which was 4.75% at March 31,June 30, 2005, plus 1%, and is

12

repayable in 120 equal monthly installments, plus interest. Substantially all of this facility was used to finance capital expenditures in Norway. The outstanding balance of this facility at March 31,June 30, 2005 was approximately U.S. $4.6$4.2 million. The facility is secured by land and buildings in Aberdeen, Scotland and contains no restrictive financial covenants.

The Company believes that cash generated from operations plus cash on hand and its existing line of credit will be sufficient to fund operations, working capital needs and anticipated capital expenditure requirements in 2005. However, any significant future declines in hydrocarbon prices could have a material adverse effect on the Company’s liquidity. Should market conditions result in unexpected cash requirements, the Company believes that additional borrowing from commercial lending institutions would be readily available and more than adequate to meet such requirements.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is currently exposed to certain market risks related to interest rate changes and fluctuations in foreign exchange rates. The Company does not believe that these risks are material. The Company does not engage in any material hedging transactions, forward contracts or currency trading which could be subject to market risks inherent to such transactions.

Foreign Exchange Rate Risk

Through its subsidiaries, the Company conducts a portion of its business in currencies other than the United States dollar, principally the British pound sterling. The Company generally attempts to minimize the associated currency exchange risks by seeking international contracts payable in local currency and in U.S. dollars. Because of this strategy, the Company has not experienced significant transaction gains or losses associated with changes in currency exchange rates and does not anticipate such exposure to be material in the future. There is no assurance that the Company will be able to protect itself against currency fluctuations in the future.

Interest Rate Risk

As described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources,” the Company has entered into two credit facilities or loans that require the Company to pay interest at a floating rate. These floating-rate obligations expose the Company to the risk of increased interest expense in the event of increases in the short-term interest rates. Based upon the March 31,June 30, 2005 balance of approximately $30.1$36.7 million related to these floating rate obligations, each 1.0% rise in interest rates would result in additional annual interest expense to the Company of approximately $300,000,$368,000, or $75,000$92,000 per quarter.

Item 4. CONTROLS AND PROCEDURES

In accordance with Exchange Act Rules 13a-15 and 15d-15, the Company carried out an evaluation, under the supervision and with the participation of management, including the Company’s Co-Chief Executive Officers and Chief Financial Officer, of the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the Company’s Co-Chief Executive Officers and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of March 31,June 30, 2005 to provide reasonable assurance that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

“Management’s Annual Reports on Internal Control over Financial Reporting” appears on page 22 of the 2004 annual report on Form 10-K.

There has been no change in the Company’s internal controls over financial reporting that occurred during the threesix months ended March 31,June 30, 2005 that has materially affected, or is reasonably likely to materially affect, the Company’s internal controls over financial reporting.
