Industry Overview and Outlook

Both the market for offshore drilling and production equipment and services and the Company’s business are substantially dependent on the financial 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. The level of capital expenditures has generally been dependent upon the prevailing view of future oil and gas prices, which are influenced by numerous factors affecting the supply and demand for oil and gas, including worldwide economic activity, interest rates and the cost of capital, environmental regulation, tax

policies, and the ability of OPEC and other producing nations to set and maintain production levels and prices. Capital expenditures are also dependent on the cost of exploring for and producing oil and gas, the sale and expiration dates of offshore leases, the discovery rate of new oil and gas reserves in offshore areas and

technological advances. Oil and gas prices and the level of offshore drilling and production activity have historically been characterized by significant volatility. See “Item 1A. Risk Factors—A material or extended declineIn general, increases in expenditures by the oil and gas industry could significantly reduce our revenueprices, rig counts and income.”new rig construction result in an increase in demand for the Company’s products and services.

HighIncreasing oil and gas prices from 2005 through 2007 havemid-2008 resulted in oil operators increasing capital spending for both exploration and development programs. As various geopolitical issues have limited the ability of oil and gas companies to invest in certain geographic areas, such as Russia and the Middle East, an increasing amount of this capital spending has beenwas in the deepwater areas in which the Company operates. However, any significant future declines in mid-2008, oil and gas prices couldbegan to decline. This decline has resulted in reduced capital spending by some oil and gas companies and may result in additional reductions in capital spending. We expect that the need for specialized products will continue and to date, we have not seen a material adverse effect on the Company’s results of operations. There can be no assurance that the current oil price levels will lead to increasesdropoff in exploration and development activity or that demand for our products during this volatile market period. See “Item 1A. Risk Factors—A material or extended decline in expenditures by the Company’s productsoil and services will reflect such increases, if any.gas industry could significantly reduce our revenue and income.”

Products and Services

Products

Dril-Quip designs, manufactures, fabricates, inspects, assembles, tests and markets subsea equipment, surface equipment and offshore rig equipment. The Company derived approximately 84%, 84% and 85% of its revenues from the sale of its products in each of 2006, 2007 2006 and 2005, respectively.2008. The Company’s products are used to explore for oil and gas on offshore drilling rigs, such as floating rigs and jack-ups, and for drilling and production of oil and gas wells on offshore platforms, TLPs, Spars and moored vessels such as FPSOs. TLPs are floating production platforms that are connected to the ocean floor via vertical mooring tethers (called tension legs). A Spar is a floating cylindrical structure approximately six or seven times longer than its diameter that is anchored in place (like a Spar buoy). FPSOs are floating production, storage and offloading monohull moored vessels.

Subsea Equipment. Subsea equipment is used in the drilling and production of offshore oil and gas wells around the world. Included in the subsea equipment product line are subsea wellheads, mudline hanger systems, specialty connectors and associated pipe, subsea production trees, valves, TLP and Spar well systems, liner hangers, multiplex subsea control systems and multiwell subsea manifolds.

Subsea wellheads are pressure-containing forged and machined metal housings in which casing hangers are landed and sealed subsea to suspend casing (downhole pipe). As drilling depth increases, successively smaller diameter casing strings are installed, each suspended by an independent casing hanger. Subsea wellheads are utilized when drilling from floating drilling rigs, either semi-submersible or drillship types, and TLPs and Spars. The Company’s SS-15 Big Bore Subsea Wellhead System is designed to accommodate additional casing strings installed through a conventional marine riser and a subsea blowout preventer.

Mudline hanger systems are used in jack-up drilling operations to support the weight of the various casing strings at the ocean floor while drilling a well. They also provide a method to disconnect the casing strings in an orderly manner at the ocean floor after the well has been drilled, and subsequently reconnect to enable production of the well by either tying it back vertically to a subsequently installed platform or by installing a subsea tree.

Large diameter weld-onspecialty connectors (threaded or stab type) are used in offshore wells drilled from floating drilling rigs, jack-ups, fixed platforms, TLPs and Spars. Specialty connectors join lengths of conductor or large diameter (16-inch or greater) casing. Specialty connectors provide a more rapid connection than other methods of connecting lengths of pipe. Connectors may be sold individually or as an assembly after being welded to sections of Company or customer supplied pipe. Dril-Quip’s weld-on specialty connectors are

designed to prevent cross threading and provide a quick, convenient method of joining casing joints with structural integrity compatible with casing strength.

Asubsea production tree is an assembly composed of valves, a wellhead connector, control equipment and various other components installed on a subsea wellhead or a mudline hanger system and used to control the flow

of oil and gas from a producing well. Subsea trees may be either stand alone satellite type or template mounted cluster arrangements. Both types typically produce via flowlines to a central control point located on a platform, TLP, Spar or FPSO. The use of subsea production trees has become an increasingly important method for producing wells located in hard-to-reach deepwater areas or economically marginal fields located in shallower waters. The Company is an established manufacturer of more complicated dual-bore production trees, which are used in severe service applications. In addition, Dril-Quip manufactures a patented single bore (SingleBore^TM) subsea completion system which features a hydraulic mechanism instead of a wireline-installed mechanism that allows the operator to plug the tubing hanger annulus remotely from the surface via a hydraulic control line and subsequently unplug it when the well is put on production. This mechanism eliminates the need for an expensive multibore installation and workover riser, thereby saving both cost and installation time. Dril-Quip’s guidelineless subsea production tree is used in ultra-deepwater applications. This tree features remote multiple flowline and control connections, utilizing remotely operated intervention tools. The Company’s subsea production trees are generally custom designed and manufactured to customer specifications.

A liner hanger is used to hang-off and seal casing into a previously installed casing string in the well bore, and can provide a means of tying back the liner for production to surface. Dril-Quip has developed a state-of-the-art liner hanger system and ishas installed its liner hangers in the final phasea number of field-performance testing. This product represents Dril-Quip’s entry into thedifficult well applications, resulting in improved industry recognition and market for downhole tools and is expected to provide new market opportunities for the Company.opportunities.

A subsea control system is used to remotely control the operations of subsea production equipment such as subsea trees and/or manifolds. In December 2005, Dril-Quip successfully delivered to an operator in the North Sea a multiplex subsea control system used to control both a subsea manifold and subsea trees. The subsea control system utilizes a “signal on power” communications system that controls a satellite subsea tree and manifold, and was designed with expansion capability to allow additional wells to be connected at a later date. Another subsea control system and subsea tree was supplied to the Dutch sector of the North Sea in the summer of 2005 and became operational in 2006. This was the first installation of Dril-Quip’s fiber optics-based communications system and continues the Company’s emergence into the high-tech subsea control systems market. The addition of this product expands Dril-Quip’s opportunities in subsea development projects.

A subsea manifold is a structure located on the ocean floor consisting of valves, chokes, flowline connections and a control module used to collect and control the flow of oil and gas from subsea wells for delivery to a terminal. Dril-Quip successfully installed its first subsea manifold system in December 2005. This new product further complements the Company’s product offerings for integrated system developments.

Surface Equipment. Surface equipment is principally used for flow control on offshore production platforms, TLPs and Spars. Included in the Company’s surface equipment product line are platform wellheads and platform production trees. Dril-Quip’s development of platform wellheads and platform production trees was facilitated by adaptation of its existing subsea wellhead and tree technology to surface wellheads and trees.

Platform wellheads are pressure-containing forged and machined metal housings in which casing hangers are landed and sealed at the platform deck to suspend casings. The Company emphasizes the use of metal-to-metal sealing wellhead systems with operational time-saving features which can be used in high pressure, high temperature and corrosive drilling and production applications.

After installation of a wellhead, a platform production tree, consisting of gate valves, a wellhead connector, controls, tree cap and associated equipment, is installed on the wellhead to control and regulate oil or gas production. Platform production trees are similar to subsea production trees but utilize less complex equipment and more manual, rather than hydraulically activated, valves and connectors. Platform wellheads and platform production trees and associated equipment are designed and manufactured in accordance with customer specifications.

Offshore Rig Equipment. Offshore rig equipment includes drilling and productioncompletion riser systems, wellhead connectors and diverters. Thedrilling riser system consists of (i) lengths of riser pipe and associated riser

connectors that secure one to another; (ii) the telescopic joint, which connects the entire drilling riser system to the diverter at the rig and provides a means to compensate for vertical motion of the rig relative to the ocean floor; and (iii) the wellhead connector, which provides a means for remote connection and disconnection of the drilling riser system to and from the blowout preventer stack.ProductionCompletion risers provide a vertical conduit from the subsea wellhead to a TLP, Spar or FPSO. Thewellhead connector also provides remote connection/disconnection of the blowout preventer stack, production tree or production riser to/from the wellhead.Diverters are used to provide protection from shallow gas blowouts and to divert gases off of the rig during the drilling operation.

Wellhead connectors and drilling and production riser systems are also used on both TLPs and Spars, which are being installed more frequently in deepwater applications. The principal markets for offshore rig equipment are new rigs, rig upgrades, TLPs and Spars. Diverters, drilling and production risers and wellhead connectors are generally designed and manufactured to customer specifications.

Certain products of the Company are used in potentially hazardous drilling, completion and production applications that can cause personal injury, product liability and environmental claims. See “Item 1A. Risk Factors—Our business involves numerous operating hazards that may not be covered by insurance.” The occurrence of an event not fully covered by insurance could have a material adverse effect on the financial condition,conditions and results of operations and cash flows of the Company.operations.”

Services

Services provided by Dril-Quip include field installationtechnical advisory services, reconditioning of its products which are customer-owned, and rental of running tools for installation and retrieval of its products. These services are provided from the Company’s worldwide locations and represented approximately 16%, 16% and 15% of revenues in each of 2006, 2007 2006 and 2005, respectively.2008.

Field Installation.Technical Advisory. Dril-Quip does not install products for its customers, but provides fieldtechnical advisory assistance to the customer, if requested, in the installation services through the use of its technicians.products. The customer is not obligated to utilize these services and may use its own personnel or a third party to perform these services. Technical advisory services performed by the Company are negotiated and sold separately from the Company’s products. These services are not a prerequisite to the sale of the Company’s products as its products are fully functional on a stand alone basis. The Company’s technicians assistprovide assistance in the onsite installation of Companythe Company’s products and are available on a 24-hour call out from the Company’s facilities located in Houston, Texas; Aberdeen, Scotland; Stavanger, Norway; Esbjerg, Denmark; Singapore; Perth, Australia; and Macae, Brazil.

Reconditioning. The Company provides reconditioning of its products at its facilities in Houston, Texas; Aberdeen, Scotland; Stavanger, Norway; Singapore; and Macae, Brazil. The Company does not service, repair or recondition its competitors’ products.

Rental. The Company rents running and installation tools for use in installing its products. These tools are used to install and retrieve Companythe Company’s products which are purchased by customers. Rental or purchase of running tools is not a condition of the sale of the Company’s products and are contracted for separately from product sales and other services offered by the Company. Running tools are available from Dril-Quip’s locations in Houston, Texas; Aberdeen, Scotland; Stavanger, Norway; Esbjerg, Denmark; Beverwijk, Holland; Singapore; Perth, Australia; Tianjin, China; and Macae, Brazil.

Manufacturing

Dril-Quip has major manufacturing facilities in Houston, Texas; Aberdeen, Scotland; Macae, Brazil; and Singapore. Each location conducts a broad variety of processes, including machining, fabrication, inspection,

assembly and testing. The Houston facility provides forged and heat treated products to all the major manufacturing facilities.

The Company’s Houston, Aberdeen and Singapore manufacturing plants are ISO 9001 and American Petroleum Institute certified. See “Properties—Major Manufacturing Facilities.” Dril-Quip maintains its high standards of product quality through the use of quality assurance specialists who work with product manufacturing personnel throughout the manufacturing process by inspecting and documenting equipment as it is

processed through the Company’s manufacturing facilities. The Company has the capability to manufacture various products from each of its product lines at its major manufacturing facilities and believes that this localized manufacturing capability is essential in order to compete with the Company’s major competitors.

The Company’s manufacturing process is vertically integrated, producing in house, a majority of its forging requirements and essentially all of its heat treatment, machining, fabrication, inspection, assembly and testing. The Company’s primary raw material is cast steel ingots, from which it produces steel shaped forgings at its forging and heat treatment facility. The Company routinely purchases steel ingots from approximately fourfive suppliers on a purchase order basis and does not have any long-term supply contracts. The Company’s Houston facility provides forgings and heat treatment for its Aberdeen, Macae and Singapore facilities. The Company’s major competitors depend on outside sources for all or a substantial portion of their forging and heat treatment requirements. The Company has made significant capital investments in developing its vertically integrated manufacturing capability. Prolonged periods of low demand in the market for offshore drilling and production equipment could have a greater effect on the Company than on certain of its competitors that have not made such large capital investments in their facilities.

Dril-Quip’s manufacturing facilities utilize state-of-the-art computer numerically controlled (“CNC”) machine tools and equipment, which contribute to the Company’s product quality and timely delivery. The Company has also developed a cost effective, in-house machine tool rebuild capability which produces “like new” machine upgrades with customized features to enhance the economic manufacture of its specialized products. The Company purchases quality used machine tools as they become available and stores them at its facilities to be rebuilt and upgraded as the need arises. Rebuilding used machine tools allows for greater customization suitable for manufacturing Dril-Quip proprietary product lines. This provides the added advantage of requiring only in-house expertise for repairs and maintenance of these machines. A significant portion of the Company’s manufacturing capacity growth has been through the rebuild/upgrade of quality used machine tools, including the replacement of outdated control systems with state-of-the-art CNC controls.

Customers

The Company’s principal customers are major integrated, large independent and foreign national oil and gas companies. Offshore drilling contractors and engineering and construction companies also represent a minor customer base. The Company’s customers are generally oil and gas companies that are well-known participants in offshore exploration and production.

The Company is not dependent on any one customer or group of customers. In 2006 and 2007, the Company’s top 15 customers represented approximately 61% and 51%, respectively of total revenues, with no customer accounting for more than 10% of the Company’s total revenues. In 2007,2008, the Company’s top 15 customers represented approximately 51%45% of total revenues, with no customer accounting for more than 10% of the Company’s total revenues. The number and variety of the Company’s products required in a given year by any one customer depends upon the amount of that customer’s capital expenditure budget devoted to offshore exploration and production and on the results of competitive bids for major projects. Consequently, a customer that accounts for a significant portion of revenues in one fiscal year may represent an immaterial portion of revenues in subsequent years. While the Company is not dependent on any one customer or group of customers, the loss of one or more of its significant customers could, at least on a short-term basis, have an adverse effect on the Company’s results of operations.

Backlog

Backlog consists of firm customer orders for which a purchase order has been received, satisfactory credit or financing arrangements exist and delivery is scheduled. The Company’s revenues for a specific period have not been directly related to its backlog as stated at a particular point in time. The Company’s backlog was approximately $336 million and $429 million at December 31, 2006 and 2007, an increase of $93 million or 28% over the backlog of

$336respectively, compared to $603 million at December 31, 2006.2008, an increase of $267 million and $174 million or 79% and 41%, respectively. This increase in backlog iswas primarily due to improving worldwide market conditions resulting in increasedcontinued demand for the Company’s products. The Company expects to fill approximately 70%65% of the December 31, 20072008 backlog by December 31, 2008.2009. The remaining backlog at December 31, 20072008 consists of longer-term projects which are being designed and manufactured to customer specifications requiring longer lead times. Our reported backlog at December 31, 2008 excludes $27 million related to the MPF contract discussed in Note 9 of Notes to Consolidated Financial Statements.

The Company can give no assurance that backlog will remain at current levels. Sales of the Company’s products are affected by prices for oil and natural gas, which fluctuated significantly between 2005 and 2007. Significanttoday. Additional future declines in oil and natural gas prices could reduce new customer orders, which would causepossibly causing a decline in the Company’s backlog to decline.future backlog. All of the Company’s projects currently included in its backlog are subject to change and/or termination at the option of the customer. In the 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. In the past, terminations and cancellations have not been significant to the Company’s overall operating results.

Marketing and Sales

Dril-Quip markets its products and services throughout the world directly through its sales personnel in two domestic and fifteen international locations. In addition, in certain foreign markets where the Company does not maintain offices, it utilizes independent sales representatives to enhance its marketing and sales efforts. Some of the locations in which Dril-Quip has sales representatives are India, Canada, Mexico, the Philippines, Brazil, Indonesia, Malaysia, China, Japan, and the Middle East. Although they do not have authority to contractually bind the Company, these representatives market the Company’s products in their respective territories in return for sales commissions. The Company also advertises its products and services in trade and technical publications targeted to its customer base. The Company also participates in industry conferences and trade shows to enhance industry awareness of its products.

The Company’s customers generally order products on a purchase order basis. Orders are typically filled within three to six months after receipt of a purchase order, depending on the type of product and whether it is sold out of inventory or requires some customization. Contracts for certain of the Company’s larger, more complex products, such as subsea production trees, drilling risers and equipment for TLPs and Spars can take a year or more to complete.

The primary factors influencing a customer’s decision to purchase the Company’s products are the quality, reliability and reputation of the product, price and technologically superior features. Timely delivery of equipment is also very important to customer operations and the Company maintains an experienced sales coordination staff to help assure such delivery. For large drilling and production system orders, project management teams coordinate customer needs with engineering, manufacturing and service organizations, as well as with subcontractors and vendors.

A portion of the Company’s business consists of designing, manufacturing and selling and installingequipment, as well as offering technical advisory assistance during installation of the equipment, for major projects pursuant to competitive bids, and thebids. The number of such projects in any year fluctuates. The Company’s profitability on such projects is critically dependent on making accurate and cost effective bids and performing efficiently in

accordance with bid specifications. Various factors can adversely affect the Company’s performance on individual projects, with potential material adverse effects on project profitability.

Product Development and Engineering

The technological demands of the oil and gas industry continue to increase as offshore exploration and drilling expand into more hostile environments. Conditions encountered in these environments include well pressures of up to 15,000 psi (pounds per square inch), mixed flows of oil and gas under high pressure that may also be highly corrosive and water depths in excess of 8,00010,000 feet. Since its founding, Dril-Quip has actively engaged in continuing product development to generate new products and improve existing products. When developing new products, the Company typically seeks to design the most technologically advanced version for a particular application to

establish its reputation and qualification in that product. Thereafter, the Company leverages its expertise in the more technologically advanced product to produce less costly and complex versions of the product for less demanding applications. The Company also focuses its activities on reducing the overall cost to the customer, which includes not only the initial capital cost but also operating and installation costs associated with its products.

The Company has continually introduced new products and product enhancements since its founding in 1981. In the 1990s, the Company introduced a series of new products, including diverters, wellhead connectors, SingleBore^TM subsea trees, improved severe service dual bore subsea trees, subsea and platform valves, platform wellheads, platform trees, subsea tree workover riser systems, drilling risers and TLP and Spar production riser systems. In 2005,Since the year 2000, Dril-Quip has introduced threemultiple new product lines:products including liner hangers, subsea control systems and subsea manifolds.

Dril-Quip’s product development work is conducted at its facilities in Houston, Texas and Aberdeen, Scotland. In addition to the work of its product development staff, the Company’s application engineering staff provides engineering services to customers in connection with the design and sales of its products. The Company’s ability to develop new products and maintain technological advantages is important to its future success. There can be no assurance that the Company will be able to develop new products, successfully differentiate itself from its competitors or adapt to evolving markets and technologies.

The Company believes that the success of its business depends more on the technical competence, creativity and marketing abilities of its employees than on any individual patent, trademark or copyright. Nevertheless, as part of its ongoing product development and manufacturing activities, Dril-Quip’s policy has been to seek patents when appropriate on inventions concerning new products and product improvements. All patent rights for products developed by employees are assigned to the Company and almost all of the Company’s products have components that are covered by patents.

Dril-Quip has numerous U.S. registered trademarks, including Dril-Quip^®, Quik-Thread^®, Quick-Stab^®, Multi-Thread^®, MS-15^®, SS-15^®, SS-10^® and SU-90^®. The Company has registered its trademarks in the countries where such registration is deemed material.

Although in the aggregate the Company’s patents and trademarks are of considerable importance to the manufacturing and marketing of many of its products, the Company does not consider any single patent or trademark or group of patents or trademarks to be material to its business as a whole, except the Dril-Quip^® trademark. At December 31, 2007, the Company held 79 U.S. patents and 182 foreign patents. The Company also relies on trade secret protection for its confidential and proprietary information. The Company routinely enters into confidentiality agreements with its employees and suppliers. There can be no assurance, however, that others will not independently obtain similar information or otherwise gain access to the Company’s trade secrets.

Competition

Dril-Quip faces significant competition from other manufacturers and suppliers of exploration and production equipment. Several of its primary competitors are diversified multinational companies with

substantially larger operating staffs and greater capital resources than those of the Company and which, in many instances, have been engaged in the manufacturing business for a much longer period of time than the Company. The Company competes principally with Vetco InternationalGray, a GE oil and gas business, and the petroleum production equipment segments of Cameron International Corporation, FMC Technologies, Inc. and Aker Kvaerner.

Because of their relative size and diversity of products, several of these companiesthe Company’s competitors have the ability to provide “turnkey” services for offshore drilling and production applications, which enables them to use their own products to the exclusion of Dril-Quip’s products. See “Item 1A. Risk Factors—We may be unable to successfully compete with other manufacturers of drilling and production equipment.” The Company also

competes to a lesser extent with a number of other companies in various products. The principal competitive factors in the petroleum drilling and production equipment markets are quality, reliability and reputation of the product, price, technology, service and timely delivery.

Employees

The total number of the Company’s employees as of December 31, 20072008 was 1,890.2,051. Of these, 1,1241,230 were located in the United States. Substantially all of the Company’s employees are not covered by collective bargaining agreements, and the Company considers its employee relations to be good.

The Company’s operations depend in part on its ability to attract quality employees. While the Company believes that its wage and salary rates are competitive and that its relationship with its labor force is good, a significant increase in the wages and salaries paid by competing employers could result in a reduction of the Company’s labor force, increases in the wage and salary rates paid by the Company or both. If either of these events were to occur, in the near-term, the profits realized by the Company from work in progress would be reduced and, in the long-term, the production capacity and profitability of the Company could be diminished and the growth potential of the Company could be impaired. See “Item 1A. Risk Factors—Loss of our key management or other personnel could adversely impact our business.”

Governmental Regulations

Many aspects of the Company’s operations are affected by political developments and are subject to both domestic and foreign governmental regulations, including those relating to oilfield operations, worker safety and the protection of the environment. In addition, the Company depends on the demand for its services from the oil and gas industry and, therefore, is affected by changing taxes, price controls and other laws and regulations relating to the oil and gas industry in general, including those specifically directed to offshore operations. The adoption of laws and regulations curtailing exploration and development drilling for oil and gas for economic or other policy reasons could adversely affect the Company’s operations by limiting demand for the Company’s products. See “Item 1A. Risk Factors—Our operations and our customers’ operations are subject to a variety of governmental laws and regulations that may increase our costs, limit the demand for our products and services or restrict our operations.”

In recent years, increased concern has been raised over the protection of the environment. Offshore drilling in certain areas has been opposed by environmental groups and, in certain areas, has been restricted. To the extent that new laws or other governmental actions prohibit or restrict offshore drilling or impose additional environmental protection requirements that result in increased costs to the oil and gas industry in general and the offshore drilling industry in particular, the business of the Company could be adversely affected. The Company cannot determine to what extent its future operations and earnings may be affected by new legislation, new regulations or changes in existing regulations. See “Item 1A. Risk Factors—Our business and our customers’ businesses are subject to environmental laws and regulations that may increase our costs, limit the demand for our products and services or restrict our operations.”

Based on the Company’s experience to date, the Company does not currently anticipate any material adverse effect on its business or consolidated financial position as a result of future compliance with existing

environmental laws and regulations controlling the discharge of materials into the environment. However, future events, such as changes in existing laws and regulations or their interpretation, more vigorous enforcement policies of regulatory agencies, or stricter or different interpretations of existing laws and regulations, may require additional expenditures by the Company, which may be material.

In this Item 1A, the terms “we,” “our,” “us,” and “Dril-Quip” used herein refer to Dril-Quip, Inc. and its subsidiaries unless otherwise indicated or as the context so requires.

Our principal stockholders have the ability to significantly influence our management and affairs and matters on which shareholders may vote.

Our principal stockholders, Larry E. Reimert, Gary D. Smith and J. Mike Walker and certain entities they control, beneficially own approximately 24%25% of our common stock and are able to exert significant control over us. The collective ownership of Messrs. Reimert, Smith and Walker may have the effect of delaying or preventing a change of control. In addition, our principal stockholders are generally not prohibited from selling their interest in us to a third party.

A material or extended decline in expenditures by the oil and gas industry could significantly reduce our revenue and income.

Our business depends upon 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. The level of capital expenditures is generally dependent on the prevailing view of future oil and gas prices, which are influenced by numerous factors affecting the supply and demand for oil and gas, including:

Oil and gas prices and the level of offshore drilling and production activity have been characterized by significant volatility in recent years. Worldwide military, political and economic events have contributed to oil and natural gas price volatility and are likely to continue to do so in the future. Although hydrocarbon prices have improved in recent years until mid-2008 and the level of offshore exploration, drilling and production activity has increased during that period, we cannot assure you that such price and activity levels will be sustained and that there will not be continued volatility in the level of drilling and production related activities. Even during periods

of high prices for oil and natural gas, companies exploring for oil and gas may cancel or curtail programs, or reduce their levels of capital expenditures for exploration and production for a variety of reasons. In addition, a significant and prolonged decline in hydrocarbon prices would likely have a material adverse effect on our results of operations.

The global financial crisis may have impacts on our business and financial condition that we currently cannot predict.

The continued credit crisis and related turmoil in the global financial system may have an impact on our business and our financial condition. The current uncertainty and turmoil in the credit markets may negatively impact the ability of our customers to finance purchases of our products and services and could result in a decrease in, or cancellation of, orders included in our backlog or adversely affect the collectability of our receivables. If the crisis reduces the availability of credit to our customers, they may reduce their drilling and production expenditures, thereby decreasing demand for our products and services, which could have a negative impact on our financial condition. Additionally, the current economic situation could have an impact on our suppliers, causing them to be unable to meet their obligations to us. Although we do not currently anticipate a need to access the credit markets in the short term, a prolonged constriction on future lending by banks or investors could result in higher interest rates on future debt obligations or could restrict our ability to obtain sufficient financing to meet our long-term operational and capital needs.

Our international operations expose us to instability and changes in economic and political conditions and other risks inherent to international business, which could have a material adverse effect on our operations or financial condition.

We have substantial international operations, with approximately 69%65%, 65%69% and 66%, respectively,69% of our revenues derived from foreign sales in each of 2006, 2007 2006 and 2005.2008, respectively. We operate our business and market our products and services in all of the significant oil and gas producing areas in the world and are, therefore, subject

to the risks customarily attendant to international operations and investments in foreign countries. Risks associated with our international operations include:

Any of these risks could have an adverse effect on our ability to manufacture products abroad or the demand for our products and services in some locations. To date, we have not experienced any significant problems in foreign countries arising from local government actions or political instability, but there is no assurance that such problems will not arise in the future. Interruption of our international operations could have a material adverse effect on our overall operations.

We are subject to taxation in many jurisdictions and there are inherent uncertainties in the final determination of our tax liabilities.

As a result of our international operations, we are subject to taxation in many jurisdictions. Therefore, the final determination of our tax liabilities involves the interpretation of the statutes and requirements of taxing authorities worldwide. Foreign income tax returns of foreign subsidiaries and related entities are routinely examined by foreign tax authorities. These tax examinations may result in assessments of additional taxes or penalties or both. Please see “Item 3. Legal Proceedings” for a description of our current dispute regarding a tax assessment in Brazil.

Our excess cash is invested in marketable securitiesvarious financial instruments which may subject us to potential losses.

We invest excess cash in various financial instruments andincluding interest bearing accounts, money market mutual funds rated at the highest qualityand funds which invest in U.S. Treasury obligations and repurchase agreements backed by nationally recognized rating agencies.Treasury obligations. However, changes in the financial markets, including interest rates, as well as the performance of the issuers, can affect the market value of our short-term investments.

We may suffer losses as a result of foreign currency fluctuations and limitations on the ability to repatriate income or capital to the U.S.

We conduct a portion of our business in currencies other than the United States dollar, and our operations are subject to fluctuations in foreign currency exchange rates. We cannot assure you that we will be able to protect the Company against such fluctuations in the future. Historically, we have not conducted business in countries that limit repatriation of earnings. However, as we expand our international operations, we may begin operating in countries that have such limitations. Further, we cannot assure you that the countries in which we currently operate will not adopt policies limiting repatriation of earnings in the future.

Our business involves numerous operating hazards that may not be covered by insurance. The occurrence of an event not fully covered by insurance could have a material adverse effect on our financial conditions and results of operations.

Our products are used in potentially hazardous drilling, completion and production applications that can cause personal injury, product liability and environmental claims. A catastrophic occurrence at a location where our equipment and/or services are used may expose us to substantial liability for personal injury, wrongful death, product liability or commercial claims. To the extent available, we maintain insurance coverage that we believe is customary in the industry. Such insurance does not, however, provide coverage for all liabilities, and we cannot assure you that our insurance coverage will be adequate to cover claims that may arise or that we will be able to maintain adequate insurance at rates we consider reasonable. The occurrence of an event not fully covered by insurance could have a material adverse effect on our financial condition and results of operations.operations, financial position and cash flows.

We may lose money on fixed-price contracts.

A portion of our business consists of the designing, manufacturing and selling and installingof our equipment for major projects pursuant to competitive bids, and is performed on a fixed-price basis. Under these contracts, we are typically responsible for all cost overruns, other than the amount of any cost overruns resulting from requested changes in order specifications. Our actual costs and any gross profit realized on these fixed-price contracts will often vary from the estimated amounts on which these contracts were originally based. This may occur for various reasons, including:

These variations and the risks inherent in our projects may result in reduced profitability or losses on projects. Depending on the size of a project, variations from estimated contract performance could have a material adverse impact on our operating results.

Our business could be adversely affected if we do not develop new products and secure and retain patents related to our products.

Technology is an important component of our business and growth strategy, and our success as a company depends to a significant extent on the development and implementation of new product designs and improvements. Whether we can continue to develop systems and services and related technologies to meet evolving industry requirements and, if so, at prices acceptable to our customers will be significant factors in determining our ability to compete in the industry in which we operate. Many of our competitors are large multinational companies that may have significantly greater financial resources than we have, and they may be able to devote greater resources to research and development of new systems, services and technologies than we are able to do.

Our ability to compete effectively will also depend on our ability to continue to obtain patents on our proprietary technology and products. As of December 31, 2007 we held 79 U.S. patents and 182 foreign patents. Although we do not consider any single patent to be material to our business as a whole, the inability to protect our future innovations through patents could have a material adverse effect.

We may be required to recognize a charge against current earnings because of percentage-of-completion accounting.

Revenues and profits on long-term project contracts are recognized on a percentage-of-completion method based onmethod. We calculate the ratiopercent complete and apply the percentage to determine revenues earned and the appropriate portion of costs incurred to the total estimated costs. Accordingly, purchase order price and cost estimates are reviewed periodically as the work progresses, and adjustments proportionate to the percentage

complete are reflected in the period when such estimates are revised. To the extent that these adjustments result in a reduction or elimination of previously reported profits, we would have to recognize a charge against current earnings, which could be significant depending on the size of the project or the adjustment.

Loss of our key management or other personnel could adversely impact our business.

We depend on the services of our executive management team, Larry E. Reimert, Gary D. Smith and J. Mike Walker. The loss of any of these officers could have a material adverse effect on our operations and financial condition. In addition, competition for skilled machinists, fabricators and technical personnel among companies that rely heavily on engineering and technology is intense, and the loss of qualified employees or an inability to attract, retain and motivate additional highly skilled employees required for the operation and expansion of our business could hinder our ability to conduct research activities successfully and develop and produce marketable products and services. While we believe that our wage rates are competitive and that our relationship with our skilled labor force is good, aA significant increase in the wages paid by competing employers could result in a reduction of our skilled labor force, increases in the wage rates paid by us or both. If either of these events were to occur, in the near-term, the profits realized by us from work in progress would be reduced and, in the long-term, our production capacity and profitability could be diminished and our growth potential could be impaired.

Our operations and our customers’ operations are subject to a variety of governmental laws and regulations that may increase our costs, limit the demand for our products and services or restrict our operations.

Our business and our customers’ businesses may be significantly affected by:

In addition, we depend on the demand for our products and services from the oil and gas industry. This demand is affected by changing taxes, price controls and other laws and regulations relating to the oil and gas industry in general, including those specifically directed to offshore operations. For example, the adoption of laws and regulations curtailing exploration and development drilling for oil and gas for economic or other policy reasons could adversely affect our operations by limiting demand for our products. We cannot determine the extent to which our future operations and earnings may be affected by new legislation, new regulations or changes in existing regulations.

Because of our foreign operations and sales, we are also subject to changes in foreign laws and regulations that may encourage or require hiring of local contractors or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. If we fail to comply with any applicable law or regulation, our business, results of operations or financial condition may be adversely affected.

Our businesses and our customers’ businesses are subject to environmental laws and regulations that may increase our costs, limit the demand for our products and services or restrict our operations.

Our operations and the operations of our customers are also subject to federal, state, and local and foreign laws and regulations relating to the protection of the environment. These environmental laws and regulations affect the products and services we design, market and sell, as well as the facilities where we manufacture our products. In addition, environmental laws and regulations could limit our customers’ exploration and production activities. We are required to invest financial and managerial resources to comply with environmental laws and regulations and anticipate that we will continue to be required to do so in the future. These laws and regulations change frequently, which makes it impossible for us to predict their cost or impact on our future operations. The

modification of existing laws or regulations or the adoption of new laws or regulations imposing more stringent environmental restrictions could adversely affect our operations.

These laws may provide for “strict liability” for damages to natural resources or threats to public health and safety, rendering a party liable for environmental damage without regard to negligence or fault on the part of such party. Sanctions for noncompliance may include revocation of permits, corrective action orders, administrative or civil penalties, and criminal prosecution. Some environmental laws and regulations provide for joint and several strict liability for remediation of spills and releases of hazardous substances. In addition, we may be subject to claims alleging personal injury or property damage as a result of alleged exposure to hazardous substances, as well as damage to natural resources. These laws and regulations also may expose us to liability for the conduct of or conditions caused by others, or for our acts that were in compliance with all applicable laws and regulations at the time such acts were performed. Any of these laws and regulations could result in claims, fines or expenditures that could be material to our earnings,results of operations, financial condition orposition and cash flow.flows.

We may be unable to successfully compete with other manufacturers of drilling and production equipment.

Several of our primary competitors are diversified multinational companies with substantially larger operating staffs and greater capital resources than ours and which have been engaged in the manufacturing business for a much longer time than us. If these competitors substantially increase the resources they devote to developing and marketing competitive products and services, we may not be able to compete effectively. Similarly, consolidation among our competitors could enhance their product and service offerings and financial resources, further intensifying competition.

The loss of a significant customer could have an adverse impact on our financial results.

Our principal customers are major integrated oil and gas companies, large independent oil and gas companies and foreign national oil and gas companies. Offshore drilling contractors and engineering and

construction companies also represent a portion of our customer base. In 2006,2007, our top 15 customers represented approximately 61%51% of total revenues, with no customer accounting for more than 10% of our total revenues. In 2007,2008, our top 15 customers represented approximately 51%45% of total revenues, with no customer accounting for more than 10% of our total revenues. While we are not dependent on any one customer or group of customers, the loss of one or more of our significant customers could, at least on a short-term basis, have an adverse effect on our results of operations.operations, financial position and cash flows.

Our customers’ industries are undergoing continuing consolidation that may impact our results of operations.

The oil and gas industry is rapidly consolidating and, as a result, some of our largest customers have consolidated and are using their size and purchasing power to seek economies of scale and pricing concessions. This consolidation may result in reduced capital spending by some of our customers or the acquisition of one or more of our primary customers, which may lead to decreased demand for our products and services. We cannot assure you that we will be able to maintain our level of sales to a customer that has consolidated or replace that revenue with increased business activity with other customers. As a result, the acquisition of one or more of our primary customers may have a significant negative impact on our results of operations or our financial condition. We are unable to predict what effect consolidations in the industry may have on price, capital spending by our customers, our selling strategies, our competitive position, our ability to retain customers or our ability to negotiate favorable agreements with our customers.

Increases in the cost of raw materials and energy used in our manufacturing processes could negatively impact our profitability.

Any increases in commodity prices for items such as nickel, molybdenum and heavy metal scrap that are used to make the steel alloys required for our products would result in an increase in our raw material costs.

Similarly, any increase in energy costs would increase our product costs. If we are not successful in raising our prices on products to compensate for any increased raw material or energy costs, our margins will be negatively impacted.

We depend on third party suppliers for timely deliveries of raw materials, and our results of operations could be adversely affected if we are unable to obtain adequate supplies in a timely manner.

Our manufacturing operations depend upon obtaining adequate supplies of raw materials from third parties. The ability of these third parties to deliver raw materials may be affected by events beyond our control. Any interruption in the supply of raw materials needed to manufacture our products could adversely affect our business, results of operations and reputation with our customers.

Our shares that are eligible for future sale may have an adverse effect on the price of our common stock.

Future sales of substantial amounts of our common stock, or a perception that such sales could occur, could adversely affect the market price of our common stock and could impair our ability to raise capital through the sale of our equity securities. This risk is compounded by the fact that a substantial portion of our common stock is owned by Messrs. Reimert, Smith and Walker and certain entities they control. Messrs. Reimert, Smith and Walker and certain entities they control have piggyback and demand registration rights that provide for the registration of the resale of shares at our expense which will allow those shares to be sold in the public market generally without restriction.

The market price of our common stock is volatile.

The trading price of our common stock and the price at which we may sell common stock in the future are subject to large fluctuations in response to any of the following:

We do not anticipate paying dividends on our common stock in the near future.

We have not paid any dividends in the past and do not intend to pay cash dividends on our common stock in the foreseeable future. Our Board of Directors reviews this policy on a regular basis in light of our earnings, financial condition and market opportunities. We currently intend to retain any earnings for the future operation and development of our business.

None.

Sales, Service and Reconditioning Facilities

The Company also performs sales, service and reconditioning activities at its facilities in Houston, Aberdeen and Singapore.

In 2006, the Company entered into a contract in the amount of approximately $47 million with MPF Corp. Ltd. (“MPF”) under which the Company was to construct risers and related equipment to be installed on an offshore drill ship being constructed for MPF. MPF and its affiliates filed a Chapter 11 bankruptcy case in September 2008 in the United States Bankruptcy Court for the Southern District of Texas, Houston Division. Under the Bankruptcy Code, at some point MPF must either assume this contract or reject it. Since MPF is not required to make a decision on the handling of the contract right away, we cannot assure you when our rights under the contract will be clarified. Currently, the Company has possession of all the raw materials purchased to date and work-in-progress under the contract. At the time of the bankruptcy filing, the Company had recognized approximately $20 million in revenues under the contract and had received payments of approximately $16 million. No further revenue has been recognized since the second quarter of 2008. The Company believes the remaining $4 million of unpaid receivables will be realized through the workings of the contract or through its interest in the partially constructed inventory. While the Company has made filings in the bankruptcy proceedings that it believes are appropriate to protect its rights, there can be no assurance that the Company will be able to receive the expected benefits of the contract with MPF. While the Company does not expect the outcome of this matter to have a material adverse effect on the Company’s operations, financial position or cash flows, the Company may be required to write down or forfeit some portion of the revenues recognized to date if it becomes probable that the Company will not receive such funds.

In August 2007, our Brazilian subsidiary was served with assessments collectively valued at approximately $12.8 million from the State of Rio de Janiero, Brazil, to collect a state tax on the importation of goods. We believe that our subsidiary is not liable for the taxes and are vigorously contesting the assessments in the Brazilian administrative and judicial systems. At this time, the ultimate disposition of this matter cannot presently be determined and therefore, it is not possible to reasonably estimate the amount of loss or the range of possible losses that might result from an adverse judgment or settlement of these assessments. Accordingly, no

liability has been accrued in conjunction with this matter. We do not expect the liability, if any, resulting from these assessments to have a material adverse effect on the Company’s operations, financial position or cash flows.

On December 1, 2006, Cameron International Corporation (“Cameron”) filed a patent infringement suit against the Company in the United States District Court for the District of Delaware. The complaint asserts that the Company has infringed and continues to infringe on certain of Cameron’s patents related to horizontal spool tree technology. The Company denies any liability. To date, the Company has not sold any horizontal spool trees. Cameron seeks injunctive relief and unspecified damages, including attorneys’ fees. Although no assurance can be given with respect to the ultimate outcome of this matter, in the opinion of management the ultimate liability with respect thereto will not have a material adverse effect on the Company’s operations, financial position or cash flows.

In August 2007, our Brazilian subsidiary was served with assessments collectively valued at approximately $12.8 million from the State of Rio de Janiero, Brazil, to collect a state tax on the importation of goods. We believe that our subsidiary is not liable for the taxes and plan to vigorously contest the assessments in the Brazilian administrative and judicial systems. At this time, the ultimate disposition of this matter cannot presently be determined and therefore, it is not possible to reasonably estimate the amount of loss or the range of possible losses that might result from an adverse judgment or settlement of these assessments. Accordingly, no liability has been accrued in conjunction with this matter. We do not expect the liability, if any, resulting from these assessments to have a material adverse effect on the Company’s operations, financial position or cash flows.

The Company also is involved in a number of legal actions arising in the ordinary course of business. Although no assurance can be given with respect to the ultimate outcome of such legal actions, in the opinion of management the ultimate liability with respect thereto will not have a material adverse effect on the Company’s operations, financial position or cash flows.

No matters were submitted to a vote of security holders of the Company during the quarter ended December 31, 2007.2008.

The following is management’s discussion and analysis of certain significant factors that have affected certain aspects of the Company’s financial position, results of operations and cash flows during the periods included in the

accompanying consolidated financial statements. This discussion should be read in conjunction with the Company’s Consolidated Financial Statements and Notes thereto presented elsewhere in this Report.

Overview

Dril-Quip designs, manufactures, sells and services highly engineered offshore drilling and production equipment that 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, subsea control systems and manifolds, mudline hanger systems, specialty connectors and associated pipe, drilling and production riser systems, liner hangers, wellhead connectors and diverters. Dril-Quip also provides technical advisory services on an as-requested basis during installation of its products, as well as rework and reconditioning services and rentsrental of running and installation 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. See “Item 1A. Risk Factors—A material or extended decline in expenditures by the oil and gas industry could significantly reduce our revenue and income.”

According to the Energy Information Administration (“EIA”) of the U.S. Department of Energy, oil (West Texas Intermediate Cushing Crude Oil) and natural gas (Henry Hub Natural Gas) prices are listed below as averages of the daily closing prices for the years 2006, 2007 and 2008:

In mid July 2008, oil prices spiked to $145.16 per barrel and ended the year in 2008 at $44.60 per barrel. Additionally, by the end of December 2008, gas prices had declined to $5.48 per Mcf. These declines in hydrocarbon prices have adversely affected the willingness of some oil and gas companies to make capital expenditures on exploration, drilling and production operations offshore, which could have an adverse impact on the Company’s financial condition and results of operations.

According to the January and February 2009 release of the Short-Term Energy Outlook published by the EIA, West Texas Intermediate crude oil prices are projected to average $43.14 per barrel in 2009 and $54.50 in 2010. In January 2009, the EIA projected Henry Hub gas prices to average $5.78 per Mcf in 2009 and increase to an average of $6.63 per Mcf in 2010. In February 2009 EIA lowered the expectation to $5.01 per Mcf in 2009 and $5.93 per Mcf in 2010. The EIA further predicted OPEC crude oil production to average 30.0 million barrels per day in 2009 and 30.7 million barrels per day in 2010. This estimate was revised downward in February 2009

to 29.4 million barrels per day in 2009 and 30.1 million barrels per day in 2010. In the January 2009 Oil Market Report, the International Energy Agency projected oil demand in 2009 to be 85.3 million barrels per day, compared to an estimated 85.8 million barrels per day in 2008. In February 2009 the International Energy Agency revised the oil demand in 2009 downward to 84.7 million barrels per day.

Detailed below is the average contracted rig count for our geographic regions for the years ended December 31, 2006, 2007 and 2008. The rig count data includes floating rigs (semi-submersibles and drill ships) and jack-ups. We have included only these types of rigs as they are the primary end users of our products.

The table represents rigs under contract and includes rigs currently drilling as well as rigs committed, but not yet drilling. Since mid-2008 the number of active offshore rigs has declined.

We believe that the number of rigs (semi-submersibles, jack-ups and drill ships) under construction impacts our revenue because our customers generally order some of our products during the construction of such rigs. As a result, an increase in rig construction activity tends to favorably impact our backlog. According to ODS-Petrodata, at the end of December 2006 and 2007, there were 112 and 156 rigs under construction, respectively, compared to 172 at the end of December 2008, which represents an increase of 53.5% and 10.3%, respectively.

Due to the significant increase in the oil and gas activity over the past several years, the Company has expanded facilities in all of its major manufacturing locations in Houston, Texas; Aberdeen, Scotland, Macae, Brazil and Singapore. With limited manufacturing capacity in the past, the Company has had to focus on which projects submitted by customers to undertake. In making the decision, the Company takes into consideration such factors as manufacturing time, current projects in progress, delivery requirements, projected gross margins, available personnel and availability of material. Based upon these decisions, it is possible for the Company to have variations between quarters and years based upon product mix.

High oil and gas prices from 2005 through 2007 havemid-2008 resulted in oil operators increasing capital spending for both exploration and development programs. As various geopolitical issues have limited the ability of oil and gas companies to invest in certain geographic areas, such as Russia and the Middle East, an increasing amount of this capital spending has been in the deepwater areas in which the Company operates. However, any significant future declines in mid-2008, oil and gas prices could have a material adverse effect on the Company’s results of operations. There can be no assurance that the currentbegan to decline. This decline has resulted in reduced capital spending by some oil price levels will lead to increasesand gas companies and may result in exploration and development activity or that demand for the Company’s products and services will reflect such increases, if any.additional reductions in capital spending.

The Company operates its business and markets its products and services in all of the significant oil and gas producing areas in the world and is, therefore, subject to the risks customarily attendant to international operations and investments in foreign countries. These risks include nationalization, expropriation, war, acts of terrorism and civil disturbance, restrictive action by local governments, limitation on repatriation of earnings, change in foreign tax laws and change in currency exchange rates, any of which could have an adverse effect on either the Company’s ability to manufacture its products in its facilities abroad or the demand in certain regions for the Company’s products or both. To date, the Company has not experienced any significant problems in foreign countries arising from local government actions or political instability, but there is no assurance that such problems will not arise in the future. Interruption of the Company’s international operations could have a material adverse effect on its overall operations. See “Item 1A. Risk Factors—Our international operations expose us to instability and changes in economic and political conditions and other risks inherent to international business, which could have a material adverse effect on our operations or financial condition.”

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. Service revenues are earned when the Company provides technical advisory service for installation andof the Company’s products, reconditioning services as well asand rental of running tools for installation and retrieval of its products. In 2007,2008, the Company derived 84% of its revenues from the sale of its products and 16% of its revenues from services. Service revenues generally correlate to revenues from product sales because increased product sales normally generate increased revenues from technical advisory services during installation services and rental of running tools. The Company has substantial international operations, with approximately 66%65%, 65%69% and 69% of its revenues derived from foreign sales in 2005, 2006, 2007 and 2007,2008, respectively. On the basis of revenues generated, approximately 65%, 66% and 62% of all products sold were manufactured in the United States during 2005, 2006 and 2007, respectively.

Generally, the Company attempts to raise its prices as its costs increase. However, the actual pricing of the Company’s products and services is impacted by a number of factors, including competitive pricing pressure, the level of utilized capacity in the oil service sector, maintenance of market share, the introduction of new products and general market conditions.

The Company accounts for larger and more complex projects that have relatively longer manufacturing time frames on a percentage-of-completion basis. During 2006 and 2007, 10 and 16 projects, respectively representing approximately 12% and 19%, of the Company’s total revenues were accounted for using the percentage-of-completion accounting. During 2008, 23 projects representing approximately 19%25% of the Company’s total revenue and 30% of the Company’s product 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 onbased upon a calculation of the ratiopercentage complete which is used to determine the revenue earned and the appropriate portion 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 percent complete are reflected in the period when such estimates are revised. Losses, if any, are recognized when they become known. Amounts received from customers in excess of revenues recognized are classified as a current liability. See “Item 1A. Risk Factors—We may be required to recognize a charge against current earnings because of percentage-of-completion accounting.”

Results of Operations

The following table sets forth, for the periods indicated, certain consolidated statements of income data expressed as a percentage of revenues:

The following table sets forth, for the periods indicated, a breakdown of our products and service revenues:

Year ended December 31, 2008 Compared to Year Ended December 31, 2007

Revenues. Revenues increased by $47.2 million, or approximately 9.5%, to $542.8 million in 2008 from $495.6 million in 2007. Product revenues increased by approximately $35.3 million for the year ended December 31, 2008 compared to the same period in 2007 as a result of increased revenues of $41.3 million in offshore rig equipment and $1.5 million in subsea equipment offset by a $7.5 million decrease in surface equipment. The increase in offshore rig equipment was primarily due to the increase in the number of long-term projects. During 2007 there were 16 projects, compared to 23 projects during 2008 and the majority of these projects related to offshore rig equipment. Of the Company’s total product revenues, product revenues increased in the Western Hemisphere, Eastern Hemisphere and Asia-Pacific by $26.5 million, $6.0 million and $2.8 million, respectively. Service revenues increased by approximately $11.9 million from increased service revenues in the Western Hemisphere of $4.8 million, Eastern Hemisphere of $2.0 million Asia-Pacific of $5.1 million. The majority of the increases in service revenues related to an increase in technical advisory assistance and reconditioning services.

Cost of Sales. Cost of sales increased by $27.0 million, or approximately 9.5%, to $312.3 million for 2008 from $285.3 million for the same period in 2007. As a percentage of revenues, cost of sales were approximately 57.6% in 2007 and 57.5% in 2008. Cost of sales as a percentage of revenue remained relatively consistent between 2007 and 2008. The increase in cost of sales in 2008 as compared to 2007 is basically consistent with the increase in revenue.

Selling, General and Administrative Expenses. For 2008, selling, general and administrative expenses increased by approximately $13.1 million, or 26.6%, to $62.4 million from $49.3 million in 2007. The increase in selling, general and administrative expenses were due to increased labor and overhead expenses resulting from increased staffing levels in the areas of sales and administration, increases in legal and professional fees, stock option expenses and the effect of foreign currency transaction gains and losses. The Company experienced approximately $3.0 million in pre-tax foreign currency transaction gains during 2007 versus approximately $2.1 million in pre-tax foreign currency transaction losses during 2008. The loss in 2008 is primarily due to the increasing strength of the U.S. dollar in the later part of 2008 as compared to the Brazilian real. Selling, general and administrative expenses as a percentage of revenues were 9.9% in 2007 and 11.5% in 2008.

Engineering and Product Development Expenses. For 2008, engineering and product development expenses increased by $3.8 million, or approximately 16.8%, to approximately $26.4 million from $22.6 million in 2007. This increase was due primarily to an increase in personnel and associated operating expenses. Engineering and product development expenses as a percentage of revenues increased from 4.6% in 2007 to 4.9% in 2008.

Interest Income. Interest income for 2008 was $3.5 million as compared to $8.3 million in 2007. This decrease was due to a reduction in interest earned on short-term investments caused by lower interest rates and reduced balances in short-term investments. Due to the global financial crisis, the Company has transferred the

majority of its short-term investments to funds which invest in U.S. Treasury obligations, which normally earn lower interest rates than money market funds. Short-term investment balances declined primarily as a result of expenditures of $100 million related to the Company’s share repurchase program.

Interest expense. Interest expense for 2008 was $182,000 compared to $370,000 in 2007.

Income tax provision. Income tax expense for 2008 was $39.4 million on income before taxes of $145.0 million, resulting in an effective income tax rate of approximately 27.2%. Income tax expense in 2007 was $38.3 million on income before taxes of $146.3 million, resulting in an effective tax rate of approximately 26.2%. In the fourth quarter of 2007 the Company benefited from a foreign development tax incentive which resulted in a reduction in income taxes of approximately $4.7 million.

Net Income. Net income was approximately $105.6 million in 2008 and $107.9 million in 2007, for the reasons set forth above.

Year ended December 31, 2007 Compared to Year Ended December 31, 2006

Revenues. Revenues increased by $52.9 million, or approximately 11.9%, to $495.6 million in 2007 from $442.7 million in 2006. Product revenues increased by approximately $45.5 million for 2007 as compared to 2006 as a result of increased revenues of $58.9 million in offshore rig equipment and $7.5 million in surface equipment offset by a decrease of $20.9 million in subsea equipment. The increase resultedin offshore rig equipment was primarily from increaseddue to the increase in the number of long-term projects. During 2006 there were 10 projects, compared to 16 projects during 2007 and the majority of these projects related to offshore rig equipment. On a geographic basis, product revenues increased in the Western Hemisphere, Eastern Hemisphere and Asia-Pacific ofby $12.7 million, $12.3 million and $20.5 million, respectively. Service revenues increased by approximately $7.4 million from increased service revenues in the Western Hemisphere of $5.0 million and Eastern Hemisphere of $3.7 million and slightly offset by a decrease in Asia-Pacific of $1.3 million. In general,The majority of 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. The increase in service revenues is essentially a result of the increase in product sales. As product revenues increase, the demand for installation services is greaterwas due to higher technical advisory assistance and the rental of running tools also increases.reconditioning services.

Cost of Sales. Cost of sales increased by $28.6 million, or approximately 11.1%, to $285.3 million for 2007 from $256.7 million for the same period in 2006. As a percentage of revenues, cost of sales were approximately 57.9% in 2006 and 57.6% in 2007 and 57.9% in 2006.2007. The reduction in cost of sales as a percentage of revenues resulted primarily from changes in product mix.

Selling, General and Administrative Expenses. For 2007, selling, general and administrative expenses increased by approximately $5.2 million, or 11.8%, to $49.3 million from $44.1 million in 2006. 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 financeadministration and increases in legal and professional fees. The Company experienced approximately $2.2 million in pre-tax foreign currency transaction gains during 2006 versus approximately $3.0 million in pre-tax foreign currency transaction gains during 2007 versus approximately $2.2 million in pre-tax foreign currency transaction gains during 2006.2007. Selling, general and administrative expenses as a percentage of revenues waswere 10.0% in 2006 and 9.9% in 2007.

Engineering and Product Development Expenses. For 2007, engineering and product development expenses increased by $3.0 million, or approximately 15.3%, to approximately $22.6 million from $19.6 million in 2006. This increase was due primarily to an increase in personnel and associated operating expenses. Engineering and product development expenses as a percentage of revenues increased from 4.4% in 2006 to 4.6% in 2007.

Interest Income. Interest income for 2007 was $8.3 million as compared to $3.6 million in 2006. The increase was due to interest earned on short-term investments resulting from excess cash flows generated.

Interest expense. Interest expense for 2007 was $370,000 compared to $669,000 in 2006. This decrease was due to the partial pay down of long-term debt and a reduction in commitment fee expenses related to the Company’s unsecured revolving line of credit.

Income tax provision. Income tax expense for 2007 was $38.3 million on income before taxes of $146.3 million, resulting in an effective income tax rate of approximately 26.2%. Income tax expense in 2006 was $38.5 million on income before taxes of $125.4 million, resulting in an effective tax rate of approximately 30.7%. This decrease in the effective tax rate reflects a reduction in foreign tax rates resulting from a foreign development tax incentive and increased tax benefits for manufacturing companies located in the United States of America.

Net Income. Net income was approximately $107.9 million in 2007 and $86.9 million in 2006, for the reasons set forth above.

Year ended December 31, 2006 Compared to Year Ended December 31, 2005

Revenues. Revenues increased by $101.9 million, or approximately 29.9%, to $442.7 million in 2006 from $340.8 million in 2005. The increase resulted primarily from increased product revenues in the Western Hemisphere, Eastern Hemisphere and Asia-Pacific of $45.5 million, $22.5 million and $13.2 million, respectively. Service revenues increased by approximately $20.7 million with increased service revenues in the Western Hemisphere of $5.2 million, Eastern Hemisphere of $11.2 million and Asia-Pacific of $4.3 million. 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. The increase in service revenues is essentially a result of the increase in product sales. As product revenues increase, the demand for installation services is greater and the rental of running tools also increases.

Cost of Sales. Cost of sales increased by $26.9 million, or approximately 11.7%, to $256.7 million for 2006 from $229.8 million for the same period in 2005. As a percentage of revenues, cost of sales were approximately 57.9% in 2006 and 67.4% in 2005. The reduction in cost of sales as a percentage of revenues resulted primarily from manufacturing efficiencies realized from the increased utilization of the Company’s manufacturing facilities, pricing and changes in product mix. This reduction occurred despite significant increases in the prices of raw materials.

Selling, General and Administrative Expenses. For 2006, selling, general and administrative expenses increased by approximately $3.2 million, or 7.7%, to $44.1 million from $40.9 million in 2005. 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 and the Company’s implementation of SFAS No. 123(R). The Company experienced approximately $2.2 million in foreign currency transaction gains during 2006 versus approximately $767,000 in foreign currency transaction losses during 2005. Selling, general and administrative expenses as a percentage of revenues declined from 12.1% in 2005 to 10.0% in 2006.

Engineering and Product Development Expenses. For 2006, engineering and product development expenses decreased by $1.3 million, or approximately 6.3%, to $19.6 million from $20.9 million in 2005. This decrease was primarily due to a reduction in engineering requirements. Engineering and product development expenses as a percentage of revenues declined from 6.1% in 2005 to 4.4% in 2006.

Interest Income. Interest income for 2006 was $3.6 million compared to $258,000 in 2005. The increase was due to interest earned on short-term investments resulting from excess cash flows generated throughout the year as well as from the partial use of proceeds from the Company’s December 2005 offering of common stock.

Interest expense. Interest expense for 2006 was $669,000 compared to $2.0 million in 2005. The decrease was primarily due to the partial use of proceeds from the Company’s December 2005 offering of common stock to pay down long-term debt.

Income tax provision. Income tax expense for 2006 was $38.5 million on income before taxes of $125.4 million, resulting in an effective tax rate of approximately 31%. Income tax expense in 2005 was $14.8 million on income before taxes of $47.4 million, also resulting in an effective tax rate of approximately 31%.

Net Income. Net income was approximately $86.9 million in 2006 and $32.6 million in 2005, for the reasons set forth above.

Liquidity and Capital Resources

Cash flows provided by (used in) operations by type of activity were as follows:

Statements of cash flows for entities with international operations that are local currency functional exclude the effects of the changes in foreign currency exchange rates that occur during any given year, as these are noncash changes. As a result, changes reflected in certain accounts on the consolidated statements of cash flows may not reflect the changes in corresponding accounts on the Consolidated Balance Sheets.

The primary liquidity needs of the Company are (i) to fund capital expenditures to improve and expand facilities and manufacture additional running tools and (ii) to fund working capital. Historically,Recently, the Company’s principal sources of funds have been cash flows from operations and bank indebtedness. In December 2005,operations.

During 2008, the Company sold 1.5generated $40.7 million shares of common stock which resulted in proceedscash from operations as compared to the Company, before expenses, of $74,880,000.

Net cash used in operating activities was $16.9 million in 2005. Net cash provided by operating activities was $93.5 million in 2006 and $82.7 million for the same period in 2007. During 2006 and 2007, net cash provided by operating activities resulted primarily from increases in net income and depreciation and amortization offset byThe primary reasons for the decrease were the changes in operating assets and liabilities.liabilities during 2008 as compared to the same period in 2007. Cash totaling approximately $84.5 million was utilized during 2008 to increase operating assets and liabilities, compared to a $42.3 million increase in operating assets and liabilities during the same period in 2007. The increase in operating assets and liabilities during 2008 primarily reflected an increase of $62.1 million in inventories due to a $174 million increase in backlog. Customer prepayments, included in trade accounts payable and other accrued expenses, increased over $25 million in 2008 due to the increase in the number of projects. Also, an increase in accounts receivable of $46.9 million was largely due to increases in unbilled project receivables.

Capital expenditures by the Company were $20.6 million, $24.1 million, and $25.2 million and $50.1 million in 2005, 2006, 2007 and 2007,2008, respectively. Capital expenditures in 2006 and 2007 included expanding manufacturing facilities in the Western Hemisphere and increased expenditures on machinery and equipment and running tools due to expanded operations. Capital expenditure increases during 2005The capital expenditures for 2008 were primarily due to expenditures related to the expansion of the Company’s Houston forging facility as well as costs associated with$16.8 million for machinery and equipment, $20.8 million for facilities and $9.3 million running tools and equipment needed in the development and marketingother expenditures of the Company’s new liner hanger and subsea controls product lines.$3.2 million. Principal payments on long-term debt were approximately $24.9$800,000, $900,000 and $800,000 in 2006, 2007 and 2008, respectively.

In May 2008 the Company announced that its Board of Directors had authorized a share repurchase program under which the Company could repurchase up to $100 million $800,000 and $900,000 in 2005, 2006 and 2007, respectively. The reduction in long-term debt during 2005 onof its common stock. At the Company’s revolving lineend of credit was due primarily to net cash provided by the sale of 1.5 million shares of common stock in the fourththird quarter of 2005.2008, the Company had repurchased 1,799,928 shares at an average price of $55.58 per share (including commissions) for a total of approximately $100 million. All repurchased shares have been retired.

The following table presents long-term contractual obligations of the Company and the related payments, excluding the effects of interest, due in total and by year as of December 31, 2007:2008:

At December 31, 2007 theThe Company hadhas a credit facility with Guaranty Bank, FSB providing an unsecured revolving line of credit of up to $10 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% or the Guaranty Bank base rate. The facility calls for quarterly interest payments and terminates on June 1, 2009. The facility also contains certain covenants including maintaining minimum tangible net worth levels, not exceeding specified funded debt amounts and required interest coverage ratios. As of December 31, 20062007 and 2007,2008, the Company had no borrowings under this facility and was in compliance with all loan covenants.

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 4.0 million (approximately U.S. $8$5.8 million). Borrowing under this facility bears interest at the Bank of Scotland base rate, which was 5.5%2.0% at December 31, 2007,2008, plus 1%, and is 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 December 31, 20062007 and 20072008 was approximately U.S. $3.4$2.7 million and U.S. $2.7$1.4 million, respectively. The facility is secured by land and buildings in Aberdeen, Scotland and contains no restrictive financial covenants.

In addition to the above, the Company has issued purchase orders in the ordinary course of business for the purchase of goods and services. These purchase orders are enforceable and legally binding. However, none of the Company’s purchase obligations call for deliveries of goods or services for time periods in excess of one year.

In October 2005, the Company filed with the SEC a universal shelf registration statement that, subject to the agreement on terms at the time of use and appropriate supplementation, allowed the Company to issue, in one or more offerings, up to $100 million of common stock, preferred stock, debt securities, warrants or a combination thereof. In December 2005, the Company issued $78 million in common stock (1.5 million shares, resulting in proceeds to the Company, before expenses, of $74.9 million.) At December 31, 2007, the Company had $22 million available under this shelf registration, subject to customary market terms and conditions.

The Company believes that cash generated from operations plus cash on hand and its current line of credit will be sufficient to fund operations, working capital needs and anticipated capital expenditure requirements in 2008.2009. 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 available and adequate to meet such requirements.

Backlog

Backlog consists of firm customer orders for which a purchase order has been received, satisfactory credit or financing arrangements exist and delivery is scheduled. The Company’s revenues for a specific period have

not been directly related to its backlog as stated at a particular point in time. The Company’s backlog was

approximately $336 million and $429 million at December 31, 2006 and 2007, an increase of $93 million or 28% over the backlog of $336respectively, compared to $603 million at December 31, 2006.2008, an increase of $267 million and $174 million or 79% and 41%, respectively. This increase in backlog is primarily due to improving worldwide market conditions resultingthe increased oil and gas prices in increased demandearly 2008. The lead time on many of the projects extends for the Company’s products.a year or more and several large projects were started in 2008. The Company expects to fill approximately 70%65% of the December 31, 20072008 backlog by December 31, 2008.2009. The remaining backlog at December 31, 20072008 consists of longer-term projects which are being designed and manufactured to customer specifications requiring longer lead times. The backlog amount at December 31, 2008 excludes $27 million related to the MPF contract as discussed in “Item 3—Legal Proceedings.”

The Company can give no assurance that backlog will remain at current levels. Sales of the Company’s products are affected by prices for oil and natural gas, which fluctuated significantly between 2005 and 2007. Significantmid-2008. Additional future declines in oil and natural gas prices could reduce new customer orders, which would causepossibly causing a decline in the Company’s backlog to decline.future backlog. All of the Company’s projects currently included in its backlog are subject to change and/or termination at the option of the customer. In the 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. In the past, terminations and cancellations have been immaterial to the Company’s overall operating results.

Geographic Segments

The Company’s operations are organized into three geographic segments—Western Hemisphere (including North and South America and Mexico; 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, as well as Macae, Brazil.

Revenues for each of these segments are dependent upon the ultimate sale of products and services to the Company’s customers. For information on revenues by geographic segment, see Note 11 of Notes to the consolidated financial statements.Consolidated Financial Statements. Revenues of the Western Hemisphere are also influenced by its sale of products to the Eastern Hemisphere and Asia-Pacific segments. Accordingly, the operating incomes of each area are closely tied to third-party sales, and the operating income of the Western Hemisphere is also dependent upon its level of intercompany sales.

Currency Risk

Through its subsidiaries, the Company conducts a portion of business in currencies other than the United States dollar, principally the British pound sterling (“GBP”) in the Eastern Hemisphere and to a lesser extent the Brazilian real.real (“BRR”) in Brazil. The Company generally attempts to minimize its currency exchange risk by seeking international contracts payable in local currency in amounts equal to the Company’s estimated operating costs payable in local currency and in U.S. dollars for the balance of the contract. 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. In 2005, 2006, 2007 and 2007,2008, the Company had, net of income taxes, gains of $1.5 million and $2.2 million, and a loss of approximately $527,000, a gain of $1,531,000 and a gain of approximately $2,184,000,$1.5 million, respectively. The U.K. intercompany balances were converted to an intercompany loan at the end of September 2006. The gainsgain in 2006 and 2007 werewas primarily due to large intercompany receivable balances due to the Company from its U.K. subsidiary, payments on the intercompany loans recorded at the historical rate, as well as the strengthening of the British pound sterling compared to the U.S. dollar. U.K. intercompany balances were converted to an intercompany loan at the end of September 2006. The GBP rose as compared to the U.S. dollar from an average of 1.77 in January 2006 to an average rate of 1.96 in December 2006. The gain in 2007 was principally due to the weakening of the U.S. dollar to the Brazilian real on the intercompany payables between Brazil and the United States. The BRR rose as compared to the U.S. dollar from the average of 0.47 in January 2007 to an average rate of 0.56 in December 2007. The loss in 2008 was primarily due to strengthening of the

U.S. dollar compared to the Brazilian real on the intercompany payables between Brazil and the United States. The BRR fell as compared to the U.S. dollar from an average of 0.59 for the first nine months of 2008 to an average rate of 0.44 for the fourth quarter of 2008.

There is no assurance that the Company will be able to protect itself against such fluctuations in the future. Historically, the Company has not conducted business in countries that limit repatriation of earnings. However, as the Company expands its international operations, it may begin operating in countries that have such limitations. Further, there can be no assurance that the countries in which the Company currently operates will not adopt policies limiting repatriation of earnings in the future. The Company also has significant investments in countries other than the United States, principally its manufacturing operations in Aberdeen, Scotland and, to a lesser extent, Singapore, Brazil and Norway. The functional currency of these foreign operations is the local

currency except for Singapore, where the U.S. dollar is used. Financial statement assets and liabilities are translated at the end of the period exchange rates. Resulting translation adjustments are reflected as a separate component of stockholders’ equity and have no current effect on earnings or cash flow.

Critical Accounting Policies

The Company’s discussion and analysis of its financial condition and results of operations are based on the Company’s consolidated financial statements,Consolidated Financial Statements, which have been prepared in accordance with generally accepted accounting principles in the United States of America. The preparation of the consolidated financial statements requires the Company to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. There can be no assurance that actual results will not differ from those estimates. The Company believes the following accounting policies affect its more significant judgments and estimates used in preparation of its consolidated financial statements.

Revenue Recognition.For

Product Revenue

The Company earns product revenues from two sources:

Revenues recognized under the time the manufacturing process is complete and the products have been shipped to the consumer. For these sales, ownership is transferred to the customer at the time of shipment. Service revenues are recorded at the time the service is rendered. percentage-of-completion method

The Company uses the percentage-of-completion method on long-term project contracts.contracts pursuant to Statement of Position 81-1 “Accounting for Performance of Construction-Type and certain Production Type-Contracts.” Long-term project contracts have the following characteristics:

For each project, the Company prepares a detailed analysis of estimated costs, profit margin, completion date and risk factors thatwhich include availability of material, production efficiencies and other factors that may impact the project. On a quarterly basis, management reviews the progress of each contract,project, which may result in

revisions of previous estimates, including revenue recognition. The Company calculates the percent complete and applies the percentage to determine the revenues earned and the appropriate portion of total estimated costs. Losses, if any, are recorded in full in the period they first become evident. Historically, the Company’s estimates of total costs and costs to complete have approximated actual costs incurred to complete the project. However, there are many factors that may impact future estimates as discussed under “Item 1A. Risk Factors”.

Under the percentage-of-completion method revenue is recognized based on the percentage of costs incurred to date compared to total cost to complete. Losses, if any, are recorded in full in the period they become evident.

Under the percentage-of-completion method, billings do not always correlate directly to the revenue recognized. Based upon the terms of the specific contract, billings may be in excess of the revenue recognized, in which case the amounts are included in customer prepayments as a liability on the Consolidated Balance Sheets. Likewise, revenue recognized may exceed customer billings in which case the amounts are reported in trade receivables. Unbilled revenues are expected to be billed and collected within the followingone year. At December 31, 2007 and 2006,2008, trade receivables included $18,129,000$18.1 million and $12,925,000$44.8 million of unbilled receivables, respectively. During 2007, 162008, 23 projects representing approximately 19%25% and 30% of the Company’s total revenue and product revenue, respectively, were accounted for using percentage-of-completion accounting.

Revenues not recognized under the percentage-of-completion method

Revenues from the sale of inventory products, not accounted for under the percentage-of-completion method, are recorded at the time the manufacturing processes is complete and ownership is transferred to the customer.

Service revenue

The Company earns service revenues from three sources:

The recognition of service revenue is the same for all products, including those accounted for under the percentage-of-completion method. The Company does not install products for our customers, but we provide technical advisory assistance. At the time of delivery of the product, the customer is not obligated to buy or rent our running tools and the Company is not obligated to perform any subsequent services relating to installation. Technical advisory assistance service revenue is recorded at the time the service is rendered. Service revenues associated with the rental of running and installation tools are recorded as earned. Rework and reconditioning service revenues are recorded when the refurbishment process is complete.

The Company normally negotiates contracts for products, including those accounted for under the percentage-of-completion method, and services separately. For all product sales, it is the customer’s decision as to when the product will be installed and if Dril-Quip running tools will be purchased or rented. Furthermore, the customer is under no obligation to utilize the Company’s technical advisory services. The customer may use a third party or their own personnel.

Inventories. Inventory costs are determined principally by the use of the first-in, first-out (FIFO) costing method, and are stated at the lower of cost or market. Inventory is valued principally using standard costs, which 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 $16.9$19.2 million and $19.2$20.8 million were recorded as of December 31, 20062007 and

2007, 2008, respectively. If market conditions are less favorable than those projected by management, additional inventory reserves may be required.

Contingent liabilities. We establish reserves for estimated loss contingencies when we believe a loss is probable and the amount of the loss can be reasonably estimated. Revisions to contingent liabilities are reflected

in income in the period in which different facts or information become known or circumstances change that affect our previous assumptions with respect to the likelihood or amount of loss. Reserves for contingent liabilities are based upon our assumptions and estimates regarding the probable outcome of the matter. Should the outcome differ from our assumptions and estimates, revisions to the estimated reserves for contingent liabilities would be required.

Off-Balance Sheet Arrangements

The Company has no derivative instruments and no off-balance sheet hedging or financing arrangements or contracts or operations that rely upon credit or similar ratings.

New Accounting Standards

In December 2007, the FASBFinancial Accounting Standards Board (“FASB”) issued SFASStatement of Financial Accounting Standards (“SFAS”) No. 141 (revised 2007), “Business Combinations” (SFAS 141(R)). SFAS 141(R) replaces Statement No. 141, “Business Combinations”.Combinations.” The statement retains the purchase method of accounting used in business combinations but replaces SFAS 141 by establishing principles and requirements for the recognition and measurement of assets, liabilities and goodwill including the requirement that most transaction costs and restructuring costs be expensed. In addition, the statement requires disclosures to enable users to evaluate the nature and financial effects of the business combination. SFAS 141(R) is effective for business combinations for whichwhen the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. We will adopt SFAS 141(R) on January 1, 2009 for acquisitionsbusiness combinations on or after this date.

In December 2007, the FASB issued FASBSFAS No. 160, “Noncontrolling Interest in Consolidated Financial Statements—an amendment to ARB No. 51” (“SFAS No. 160”)(SFAS 160) which establishes accounting and reporting standards for noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. The provision of SFAS No. 160 are effective for fiscal years beginning after December 15, 2008. The Company does not believe the provisions pfof this statement will materially effect the results of operations.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115” (SFAS 159). SFAS 159 permits entities to choose to measure eligible financial assets and liabilities at fair value. Unrealized gains and loses on items for which the fair value option has been elected are reported in earnings. SFAS 159 is effective for years beginning after November 15, 2007. We adopted SFAS 159 on January 1, 2008 and did not elect to apply the fair value method to any eligible assets or liabilities at that time.

The Company adopted the provisions of FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109” (“FIN 48”), on January 1, 2007. FIN 48 was issued in June 2006 and prescribes that the Company recognize in its financial statements the impact of a tax position that is more likely than not to be sustained upon examination based upon the technical merits of the position, including resolution of any appeals. The interpretation provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

Based on our evaluation, we have concluded that there are no significant uncertain tax positions requiring recognition in our financial statements. Our evaluation was performed for the tax years which remain subject to examination by major tax jurisdictions as of December 31, 2007,2008, which are the years ended December 31, 2001,2003 through 2007.

2008. We may from time to time be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to our financial results.

In September 2006, the Financial Accounting Standards BoardFASB issued FASBSFAS Statement No. 157, “Fair Value Measurements” (or SFAS(SFAS 157), which defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles, and expands disclosures under fair value measurements. SFAS 157 applies to other accounting pronouncements that require or permit fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007. However, on February 12, 2008, the FASB issued FSP (FASB Staff Position) FAS 157-2 which would delay the effective date of SFAS 157 for all nonfinancial assets and nonfinancial

liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). This FSP partially defers the effective date of StatementSFAS 157 to fiscal years beginning after November 15, 2008, and interim periods within those fiscal years for items within the scope of this FSP. Effective forJanuary 1, 2008, we will adoptadopted SFAS 157 except as it applies to those nonfinancial assets and nonfinancial liabilities as noted in FSP FAS 157-2. We are currently evaluatingIn October 2008, the potentialFASB issued FSP FAS 157-3, “Determining the Fair Value of a Financial Asset When the Market for That Asset Is Not Active.” FSP FAS 157-3 clarifies the application of SFAS 157 in a market that is not active and addresses application issues such as use of internal assumptions when relevant observable data does not exist, the use of observable market information when the market is not active and the use of market quotes when assessing the relevance of observable and unobservable data. FSP FAS 157-3 was effective immediately and did not have an impact on ourthe Company upon adoption. The Company did not have any assets or liabilities that would be recognized or disclosed on a fair value basis as of December 31, 2008. Cash and cash equivalents include investments in various financial statements, if any, upon adoption of this standard.instruments which are carried at cost.

The Company is currently exposed to certain market risks related to interest rate changes and fluctuations in foreign exchange rates. The Company does not engage in any material hedging transactions, forward contracts or currency trading which could mitigate the market risks inherent in 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 and to a lesser extent, the Brazilian real. 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. However, there is no assurance that the Company will be able to protect itself against currency fluctuations in the future. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Currency Risk” in Item 7 of this report.

The Company uses a sensitivity analysis model to measure the impact on revenue and net income of a 10% adverse movement of foreign currency exchange rates against the U.S. dollar over the previous year. Based upon this model, a 10% decrease would result in a decrease in revenues of approximately $22.1$22 million and a decrease in net income of approximately $7.1$8 million over this period. There can be no assurance that the exchange rate decrease projected above will materialize as fluctuations in exchange rates are beyond the Company’s control.

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 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 December 31, 20072008 balance of approximately $2.7$1.4 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 $27,000,$14,000, or $6,750$3,500 per quarter.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America and includes those policies and procedures that:

Management has designed its internal control over financial reporting to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with accounting principles generally accepted in the United States of America. Management’s assessment included review and testing of both the design effectiveness and operating effectiveness of controls over all relevant assertions related to all significant accounts and disclosures in the financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our principal executive officers and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework inInternal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework inInternal Control—Integrated Framework, our management has concluded that our internal control over financial reporting was effective as of December 31, 2007.2008.

BDO Seidman, LLP, the independent registered public accounting firm, which audited the consolidated financial statements included in the annual report, has also issued an attestation on our internal control over financial reporting, and their report is set forth on page 31.35.

Dril-Quip, Inc.

Houston, Texas

We have audited Dril-Quip, Inc.’s internal control over financial reporting as of December 31, 2007,2008, based on criteria established inInternal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Dril-Quip, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying “Item 9A. Management’s Annual Report on Internal Control Over Financial Reporting”. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Dril-Quip, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007,2008, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Dril-Quip, Inc. as of December 31, 20072008 and 2006,2007, and the related consolidated statements of income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 20072008 and our report dated February 28, 200826, 2009 expressed an unqualified opinion thereon.
