PART I

Item 1.    Business

Overview

        Mueller Water Products, Inc. is a Delaware corporation that was incorporated in 1999 for the purpose of acquiring our business from Tyco International (U.S.) Inc. and its affiliates. In November 2004, we changed our name from Mueller Holdings (N.A.), Inc. to Mueller Water Products, Inc. Our operating subsidiaries are engaged primarily in the sourcing, manufacture and sale of flow control products, including fire hydrants, gate valves and piping components, in the United States and other countries. Our operations are divided into two reporting segments based largely on the end markets they serve: water infrastructure and piping systems.

        We are a leading North American manufacturer of a broad range of water infrastructure and flow control products for use in water distribution networks, water and wastewater treatment facilities, gas distribution systems and piping systems. We maintain a large installed base of products in the United States, including approximately three million fire hydrants and eight million iron gate valves. Our water infrastructure products include hydrants, valves and a variety of related products and our piping systems products include pipe fittings, pipe hangers and pipe nipples and a variety of related products. We believe we have the broadest product line of any of our competitors and enjoy strong market positions, leading brand recognition and a strong reputation for quality and service within the markets we serve.

        The following charts illustrate the balance and diversity of our revenue base by end market and product category and identify the approximate percentage of our revenues by product category:

Revenues By Product Category		Revenues By End Market Served

        Sales of our water infrastructure products, which comprised 59% of our sales in 2004, are driven principally by spending on water and wastewater infrastructure upgrade, repair and replacement and new water and wastewater infrastructure (which spending is driven primarily by new residential construction). Of our water infrastructure sales, we estimate that approximately 55% are for new infrastructure, with the remainder for upgrade, repair and replacement. Sales of our piping systems products, which comprised 41% of our sales in 2004, are driven principally by spending on non-residential construction projects.

        Our large installed base, broad product range and well known brands have led to our strong, long-standing relationships with all of the leading distributors in our industry. We believe that our network of over 5,000 independent flow control distributors is the largest such distribution network in the United States and Canada. Our sales force of approximately 350 field sales representatives and manufacturer's representatives works directly with municipalities and other end-users as well as with distributors, which market our products to end-users. For most of our water infrastructure products, which are sold through independent distributors, end-users choose the brand or establish product

specifications. We believe our reputation for quality, extensive distributor relationships, installed base and our coordinated marketing approach have helped our water infrastructure products to be "specified" as an approved product for use in most major metropolitan areas throughout the United States. This specification dynamic and our relationships with end-users elevate the importance of our water and wastewater infrastructure products to our distributors.

        Our products are sold to a wide variety of end-users, including municipalities, publicly and privately-owned water and wastewater utilities, gas utilities and construction contractors. We believe that our sales are substantially driven by water infrastructure replacement, repair and upgrades, new water and wastewater infrastructure spending and non-residential construction. Our diverse end markets, extensive distributor and end-user relationships, acquisition strategy and market leading position have contributed to our strong operating margins and sales growth. We have grown our sales every year since 1999, except 2001. We have achieved this growth despite softness in the general economy and non-residential construction market in 2001, 2002 and 2003. In 2004, we experienced strong sales growth driven primarily by the beginning of a general economic recovery, which has resulted in increased spending by municipalities on water infrastructure replacement, repair and upgrades, increased activity in the non-residential construction market and continued strength in residential construction. For the fiscal year ended September 30, 2004, our net sales were $1,049.2 million, representing an increase of 13.7% over the fiscal year ended September 30, 2003.

Business Strategy

        Our business strategy is focused on sustaining our market leadership and competitive differentiation, while growing revenues and enhancing profitability. Key elements of our strategy include:

•

Capitalize on Attractive Water Infrastructure Industry.  Much of the water distribution infrastructure in the United States is aging and in need of replacement or updating. Our strategy is to capitalize on expected water infrastructure market growth by continuing to offer a broad range of leading water and wastewater products, maintaining our strong end-user and distributor relationships, and leveraging our specification position and large installed base.



•

Leverage Strong Distributor Channel.  Our strategy is to maximize and continue to form close relationships with the strongest and fastest growing distributors in the industries we serve and utilize our extensive distributor relationships to increase sales of our products.



•

Continue to Focus on Operational Excellence.  We will continue to pursue superior product engineering, design and innovation through our technologically-advanced manufacturing processes. We employ highly efficient manufacturing methods, such as lost foam casting and automated Disamatic mold-making, to enhance product quality and reduce costs. We will also continue to seek opportunities to rationalize our manufacturing facilities and use our significant manufacturing expertise to further reduce our cost structure.



•

Selectively Pursue Strategic Acquisitions.  Certain segments of the industry in which we compete are fragmented, which provides attractive acquisition opportunities. We intend to pursue these opportunities to complement and expand our product lines, expand our market share, provide substantial synergy opportunities, and improve our presence in certain under-represented product categories and geographies.



•

Selectively Expand Internationally.  We are exploring sales opportunities for our products in selected international markets including Europe and China, although to date we have not generated significant revenues outside of North America.

Product Segments

        We believe that we are the broadest full-line supplier of flow control products for water and wastewater infrastructure systems and piping component systems in the United States and Canada. We manufacture more than 72,000 flow control products for water and gas systems, ranging from fire hydrants to ¹/8 inch pipe fittings that connect pipes together to 10-foot engineered valves. Our principal products are fire hydrants, water and gas valves, and a complete range of pipe fittings, couplings, hangers and nipples. Our products are designed, manufactured and tested in compliance with industry standards.

        We sell our products through two operating segments: water infrastructure, through which we sell our hydrants and valves and other water and wastewater infrastructure and gas distribution products described below under various brand names including Mueller, Henry Pratt, Hersey and James Jones; and piping systems, through which we sell our piping systems products under various brand names, including Anvil, Beck and Merit.

Water Infrastructure Products

        Fire Hydrants.    We believe we are one of the largest manufacturers of dry-barrel fire hydrants in the United States and Canada. New fire hydrant and fire hydrant part sales accounted for approximately $122.7 million, $125.0 million and $151.2 million of our total sales in 2002, 2003 and 2004, respectively. Fire hydrants are sold for new water infrastructure development as well as water infrastructure rehabilitation projects.

        Our fire hydrants consist of an above-ground fire hydrant and a below-ground cast iron pipe that connects to a water main. In our dry-barrel hydrants, the valve connecting the barrel of the hydrant and the water main is located below ground at or below the frost line, which keeps the hydrant "dry" and the water source deep enough to ensure that the water does not freeze. We market our dry-barrel fire hydrants with the Mueller brand name in the United States and the Mueller and Canada Valve brand names in Canada, and manufacture them in our Albertville, Alabama and Milton, Ontario facilities. We also make a limited number of wet barrel hydrants, where the valve is placed inside the above-ground hydrant and the barrel contains water in it at all times. Wet barrel hydrants are made for the California and Hawaii markets and sold under the James Jones brand name.

        Most municipalities have a limited number of hydrant brands that are approved for installation within their system due to the need to maintain inventories of spare parts for emergency repairs and the desire to ensure a uniform system. We believe that our large installed base of hydrants throughout the United States and Canada and our reputation for superior quality and performance, together with our incumbent specification position, have contributed to our leading market share. Our large installed base of approximately three million hydrants also leads to recurring revenue.

        Water and Gas Valves and Related Products.    We believe we have the broadest product line of valves for residential water and gas systems and that we are one of the largest manufacturers of butterfly valves and water gate valves in the United States and Canada. Water and gas valves and related products accounted for approximately $353.1 million, $381.3 million and $437.4 million of our sales in 2002, 2003, and 2004, respectively. Our significant industry-leading market position is the result of our strong brand recognition, superior quality and specification acceptance.

        All of our valve products are used to control transmission of potable water, non-potable water or gas. Our product line includes butterfly, gate, tapping, check, plug and ball valves. Water valve products range in size from ³/4 inch to 10 feet. The smaller iron gate-type valves are produced by our Chattanooga, Tennessee plant and the larger iron AWWA—butterfly valves are produced by our Henry Pratt subsidiary in Dixon, Illinois. Brass valves are produced in our Decatur, Illinois and El Monte, California plants. Most of these valves are used in water distribution.

5

        We produce small iron valves, meter bars, and line stopper fittings for use in gas systems in our Decatur, Illinois and Brownsville, Texas plants. We also manufacture machines and tools for tapping, drilling, extraction, installation and stopping-off. These machines and tools are designed to work with our water and gas fittings and valves as an integrated system. We believe that we are one of the largest manufacturers in the line stopper fittings and machines sector in the United States and Canada.

        Other Water Infrastructure Products.    Our other water infrastructure products include: pipe repair products, such as repair clamps and couplings used to repair leaks in water and gas distribution systems; municipal castings, such as manhole covers and street drain grates; and patterns used by the foundry and automotive industries. We market these products under the Mueller, Mueller Canada, James Jones, and Viking Johnson brand names. These products accounted for $45.2 million, $45.2 million and $46.6 million of our sales in 2002, 2003 and 2004, respectively.

Piping Systems Products

        Pipe Fittings and Couplings.    We are one of the largest manufacturers of threaded and grooved pipe fittings and couplings in the United States and Canada. Pipe fittings and couplings join two pipes together. Listed below are the four primary categories of pipe fittings and couplings that we manufacture.

        Malleable Iron Fittings and Unions.    Malleable iron fittings and unions accounted for sales of $73.8 million, $68.9 million and $66.0 million in 2002, 2003, and 2004, respectively. Malleable iron is a cast iron that is heat-treated to make it stronger, which allows us to use a thinner wall and results in a lighter product. Malleable iron is primarily used to join pipe in various gas, plumbing and HVAC applications. We manufacture these products at our Columbia, Pennsylvania foundry.

        Cast Iron Fittings.    We believe we are one of the largest manufacturers of cast iron fittings in the United States. Cast iron fittings accounted for approximately $36.2 million, $31.8 million and $31.7 million of our sales in 2002, 2003, and 2004, respectively. Cast iron is the most economical threaded fittings material and is typically used in low pressure applications such as sprinkler systems and other fire protection systems. We manufacture cast iron fittings primarily in our Columbia, Pennsylvania foundry. We believe that the substantial majority of our cast iron product is used in the fire protection industry, with the remainder used in steam and other HVAC applications.

        Threaded Steel Pipe Couplings.    We believe we are one of the largest manufacturers of threaded steel pipe couplings in the United States and Canada. Threaded steel pipe couplings accounted for sales of $26.1 million, $24.5 million and $32.8 million in 2002, 2003 and 2004, respectively. Threaded steel pipe couplings are used in the plumbing and electrical markets to join pipe and conduit and by pipe mills as threaded end protectors. We manufacture steel couplings at our Waynesboro, Pennsylvania and Simcoe, Ontario facilities.

        Grooved Products.    We believe we are one of the largest manufacturers of grooved products in the United States and Canada. Sales of grooved products were approximately $47.4 million, $52.0 million and $56.1 million in 2002, 2003 and 2004, respectively. Unlike typical pipe connections, where pipes are connected by screwing them into a fitting or welding them together, grooved products use a threadless pipe-joining method that does not require welding. We manufacture our grooved couplings and fittings under the Gruvlok name in our Columbia, Pennsylvania foundry. In addition, we purchase privately labeled products to complement our grooved product offerings including grooved copper and stainless steel fittings. These additional purchased products complement our offering of grooved products and enable us to better serve our customers' project requirements. Purchased products accounted for $12.5 million, $15.1 million and $17.2 million of grooved product sales in 2002, 2003 and 2004, respectively.

6

        In connection with our acquisition from Tyco in August 1999, we entered into a five-year agreement that granted Tyco the exclusive right to distribute our Gruvlok products in Europe, Asia and Latin America. That agreement expired in August 2004 and we are in the process of engaging new distributors for these products in Europe, which we view as a growth opportunity.

        Pipe Hangers.    We believe we are one of the largest manufacturers of pipe hangers in the United States and Canada. Our annual hanger sales were approximately $44.7 million, $42.3 million and $38.5 million in 2002, 2003 and 2004, respectively. Pipe hangers provide support for pipes and are used in sprinkler systems, HVAC applications and in power and petrochemical plants. We manufacture our standard pipe hangers in Henderson, Tennessee and Columbia, Pennsylvania and we produce special order, or engineered, pipe hangers in North Kingston, Rhode Island. We have retained a strong core engineering staff and believe that we are the leader in technical competency in this sector.

        Pipe Nipples.    We believe we are also one of the largest manufacturers of pipe nipples in the United States and Canada. Sales of pipe nipples were approximately $39.1 million, $46.1 million and $53.4 million in 2002, 2003 and 2004, respectively. The pipe nipple product line is a complementary product offering and is packaged (1) with cast iron for the fire protection market, (2) with malleable iron for the industrial market, (3) with our forged steel product line and (4) as a general plumbing market item.

        We increased our pipe nipple production by approximately 50% through the 2001 acquisition of Beck Manufacturing. We produce the majority of our pipe nipple products at Beck Manufacturing's facilities in Greencastle, Pennsylvania and Santa Fe Springs, California. Seamless pipe nipples are produced at our Longview, Texas facility. Pipe nipples for the Canadian market are manufactured at our Simcoe, Ontario facility.

        Other Piping Systems Products.    In addition to our key products that we have described above, we sell (1) products sourced outside the United States and Canada through our Star business, which we acquired in January 2004, (2) products that we purchase from third parties and (3) many other products that we manufacture, including (A) oilfield products, including forged steel pipe fittings, hammer unions, bull plugs and swage nipples which are used to connect pipes in oil and gas applications and (B) electrical products, including PVC conduit couplings and elbows used to carry wire and cable in electrical applications. Sales of purchased products by our piping systems products segment were approximately $85.3 million, $86.4 million and $117.5 million in 2002, 2003 and 2004, respectively, and sales of our other manufactured products were approximately $52.2 million, $53.8 million and $58.2 million in 2002, 2003 and 2004, respectively.

Sales, Marketing and Distribution

        Our products are sold to a wide variety of end-users, including municipalities, publicly and privately owned water and wastewater utilities, gas utilities and construction contractors. Our products are usually purchased from us by our distributors; distributors then sell our products to contractors who have won a contract to construct, replace or upgrade a water, wastewater or gas system for an end-user or non-residential facility. In some cases, end-users, including municipalities and utilities, buy products directly from us, most often as part of a program to repair, replace or upgrade existing infrastructure. Sales of our water infrastructure products and our piping systems grooved products are heavily influenced by the specifications in those contracts. Our sales force of approximately 350 sales representatives calls on municipalities, water companies and other end-users to ensure that our products, or the corresponding quality standards, are specified. In addition, to ensure consistency, municipalities often require that contractors use the same products that have been historically used in that municipality. Sales of our piping systems products are generally influenced by the distributors, as customers will buy from a distributors' available offering based on price and quality.

7

        Our large installed base, broad product range and well known brands have led to our strong, long-standing relationships with all of the leading distributors in our industry. For most of our water infrastructure products, which are sold through independent distributors, end-users choose the brand or establish product specifications. Our distribution network includes approximately 5,000 distributors that cover all of the major markets in the United States and Canada. We typically do not have long-term contracts with our distributors, although we have long-term relationships with most of our top distributors. Our three major distributors accounted, in the aggregate, for approximately 31% of our sales in 2004. The loss of any one of these distributors could have a material adverse effect on our business. See "—Risk Factors—We depend on a group of major distributors for a significant portion of our sales; any loss of these distributors could reduce our sales and continuing consolidation could cause price pressure."

        We generally ship our water infrastructure products, including hydrants and water and gas valves, directly to distributors carrying these products from our plant. We generally ship our piping systems products, including pipe fittings, couplings, hangers and nipples, from our plants to four regional service centers that we operate in the United States and we ship products from these distribution centers to distributors carrying these products. Our regional service centers are strategically located to provide 24-hour delivery to the majority of our piping systems customers. In addition, we operate 24 smaller warehouses throughout the United States and Canada to support our piping systems operations. We have historically stocked some products manufactured by third parties in these distribution centers in order to provide a broader product offering. We reduced the scope of our offering of piping systems products purchased from third parties, which are lower margin, in the United States following our acquisition by our current equity owners. We continue to sell a broad range of purchased products in Canada.

Backlog

        Our backlog is not significant due to our ability to respond adequately to customer requests for product shipments. We generally manufacture our products from raw materials in stock and deliver them to customers within approximately two weeks from receipt of the order, depending upon customer delivery specifications.

Manufacturing

        We operate 29 highly automated manufacturing facilities in the United States, Canada and China. Our manufacturing operations include foundry, machining, fabrication, assembly, testing and painting operations. We believe that our existing manufacturing capacity is sufficient for our near-term requirements and we have no current plans to expand capacity.

        We use two primary casting techniques, green sand and lost foam. At present, we utilize the lost foam technology for hydrants in our Albertville, Alabama facility and for gate valve production in our Chattanooga, Tennessee facility. The lost foam process has several advantages over the green sand process for high-volume products, including the need for less manual finishing, lower scrap levels and the ability to reuse the sand.

        The selection of the appropriate casting method, pattern, core-making equipment, sand and other raw materials depends on the final product and its complexity, specifications, and function as well as intended production volumes. We will continue to use the green sand casting process for products when we believe it is the most appropriate process based on the above parameters.

8

Raw Materials

        Our products are made from several basic raw materials, including sand, resin, brass ingot, steel pipe, and scrap steel and iron. These materials are readily available and are competitively priced. Historically, we have been able to obtain an adequate supply of raw materials and do not anticipate any shortage of these materials.

        We generally purchase raw materials at spot prices and do not hedge our exposure to price changes. Our business could be adversely affected by increases in the cost of our raw materials, as we may not be able to fully pass these costs on to our customers. From March 2002 to December 2003, the United States imposed tariffs on imported steel and steel pipe, which are raw materials for pipe nipples and hangers, sales of which represent approximately 9% of our revenues. The tariffs along with a consolidation of capacity in the steel pipe manufacturing industry resulted in an approximate 17% increase in the price of steel pipe from a pre-tariff price of $552 per ton to $645 per ton, the price of steel pipe when the tariffs were removed. To offset this increase we raised the price of our products; however, our price increases lagged the increases in the price of steel which, in turn, adversely affected our results. Although the tariffs on imported steel were removed in December 2003, prices have not decreased to pre-tariff levels as foreign producers had shifted to customers outside the United States, causing supply shortages. We can give no assurances that tariffs will not be re-imposed or imposed on other materials that we use to produce our products or that steel prices will return to pre-tariff levels. In addition, increased worldwide demand for steel scrap, the raw material from which our threaded and grooved pipe fittings as well as all iron valves and hydrants are made, has increased the spot price of steel scrap from approximately $140 per ton in December 2002 to approximately $400 per ton in September 2004. Steel producers have also announced that they intend to further raise prices. Management estimates that raw materials and purchased components used in our manufacturing processes accounted for 10-15% of our cost of goods sold in 2001 through 2003 and currently account for approximately 15-17% of our cost of goods sold due to increasing raw material prices.

Research and Development

        We have a dedicated team of research and development ("R&D") professionals, who focus on the development of new products as well as on the support, modification and improvement of existing products. Presently, we employ 9 degreed engineers dedicated to R&D activities. Our R&D effort is operated out of our facility in Smithfield, Rhode Island.

        Ideas are generated by manufacturing, marketing or R&D personnel. In order for a project to move beyond the idea stage, all three disciplines must agree on the suitability of the product and determine an estimated payback. After the approval, it typically takes 6 to 12 months to tool, test and start production. The R&D team typically works on various products at one time. We spent approximately $5.5 million, $4.7 million and $4.4 million on R&D activities in 2002, 2003 and 2004, respectively.

Patents, Licenses and Trademarks

        We have a significant number of active patents and trademarks relating to the design of our products. Most of the patents for technology underlying our products have been in the public domain for many years, and existing third-party patents are not considered, either individually or in the aggregate, to be material to our business. However, the pool of proprietary information, consisting of know-how and trade secrets relating to the design, manufacture and operations of our products is considered particularly important and valuable. We generally own the rights to the products that we manufacture and sell and are not dependent in any material way upon any license or franchise to operate.

        In connection with the acquisition of Mueller by the DLJ Merchant Banking funds from Tyco in August 1999, we acquired a non-exclusive license to use the Mueller brand name for a period of two

9

years, with an option to purchase it in September 2001 and to use the Grinnell name for three years. We exercised the option and purchased the Mueller intellectual property in September 2001, the Grinnell license expired in 2002, and we therefore no longer incur related royalty expense.

Seasonality

        See "Item 7.—Management's Discussion and Analysis of Financial Condition and Results of Operations—Effect of Inflation; Seasonality."

Competition

        The domestic and international markets for flow control products are competitive, However, for most of our product offerings, there are only a few competitors. Although many of our competitors are well-established companies with strong brand recognition, we believe that we maintain a strong competitive position for each of our key product offerings. Management considers product quality, service, brand recognition, price, effectiveness of distribution and technical support to be primary competitive factors.

        Management believes the competitive environment for our water infrastructure products is mature and stable with limited movement in market share over time. While the competitive environment for piping products is also mature, it is less stable than the water infrastructure products market, is more price sensitive and vulnerable to the increased acceptance of foreign products.

        With regard to our piping products segment, our products have mechanical and industrial applications, such as HVAC systems, and fire protection applications, such as sprinkler systems. We estimate that 70% of our piping systems products are used in mechanical applications and the remainder in fire protection systems. While the mechanical market has generally resisted acceptance of foreign products, the fire protection market has broadly accepted foreign products as a substitute for domestic piping system products. Fire protection products are sold primarily on price and are sold at lower prices by foreign manufacturers.

        Over the past two years, we have successfully petitioned the International Trade Commission and the Department of Commerce to impose anti-dumping duties on certain malleable and non-malleable pipe fitting products imported from China. While we believe that these duties will favorably impact our business, which is very competitive, there is no assurance that the anti-dumping duties imposed will be sufficient to reverse or retard the imports from China.

        In January 2004, we acquired the assets of the building and construction division of Star Pipe, Inc., an established importer of threaded and grooved pipe fittings produced in China and India. Our acquisition of Star has allowed us to establish a significant presence in the market for lower cost, foreign produced fire protection products and grow our overall market share.

Environmental Matters

        In the Acquisition Agreement pursuant to which the DLJ Merchant Banking funds acquired Mueller in August 1999, Tyco agreed to indemnify us and our affiliates for all "Excluded Liabilities". Excluded Liabilities include, among other things, substantially all liabilities relating to the time prior to the closing of DLJMB's acquisition of Mueller. The indemnity survives indefinitely and is not subject to any deductibles or caps. However, we may be responsible for these liabilities in the event that Tyco ever becomes financially unable to, or otherwise fails to comply with, the terms of the indemnity. In addition, Tyco's indemnity does not cover environmental liabilities to the extent caused by our company or the operation of our business after the acquisition or to the extent arising with respect to any business or site acquired by us after August 1999.

        We are subject to various laws and regulation relating to health, safety and the protection of the environment. These laws relate to, among other things, worker health and safety and the use, discharge

and disposal of regulated substances and wastewater generated during our manufacturing processes. As a result, we are required to obtain and maintain air, storm water, wastewater and other permits at many of our facilities, and make certain regular reports to federal, state and local agencies regarding our operations. We cannot assure you that we will not incur material fines, penalties, costs or liabilities in connection with such requirements or a failure to comply with them. While we currently incur capital and other expenditures to comply with these environmental, health and safety laws, these laws may become more stringent and our processes may change. Therefore, the amount and timing of such expenditures in the future may vary substantially from those currently anticipated.

        Some environmental laws require investigation and cleanup of environmental contamination at properties we now or previously owned, leased or operated. Some of our operations (in particular, operations at our manufacturing facilities) have been conducted at their current locations for many years. The processes at these and our other facilities currently and historically have involved the storage and use of regulated substances on-site or in underground storage tanks and the related generation of solid and hazardous waste disposed of off-site or in on-site solid waste landfills. Remediation projects are being undertaken at a handful of our sites by third parties who have indemnified us. We may be required to conduct and pay for these or other remedial activities in the future, and also may be subject to claims for property damage, personal injury, natural resource damages or other issues as a result of such matters. See "—Legal Proceedings" for further details.

        In addition, we have received notices from third parties or governmental agencies of liability or potential liability in connection with our off-site disposal of solid and hazardous substances relating to our current and former operations. While we currently anticipate that expenditures relating to these sites will not be material, we may receive additional notices and the amount and timing of expenditures relating to known or unknown sites may vary substantially from those currently anticipated.

        On April 22, 2004, the EPA issued final National Emissions Standards for Hazardous Air Pollutants (NESHAP's) under the federal Clean Air Act for iron and steel foundries. The NESHAP for iron and steel foundries will require reductions in hazardous air pollutant emissions by the industry. In addition, other NESHAP's apply to painting operations at our foundries. While we are in the process of analyzing the impact these standards may have on us and our future financial results, we expect we will need to incur additional and possibly material costs to comply with the regulations with respect to our Albertville, Alabama and Chattanooga, Tennessee facilities and may need to incur additional and possibly material costs with respect to our Columbia, Pennsylvania facility. See "—Risk Factors—We may be adversely affected by environmental, health and safety laws and regulations or liabilities," "—Risk Factors—Our brass products contain lead, which may be replaced in the future" and "—Risk Factors—Certain of our products may not be in compliance with NSF standards, which could limit the ability of municipalities to buy our products".

Regulatory Matters

        The production and marketing of our products is subject to the rules and regulations of various federal, state and local agencies, including laws governing our relationships with distributors. Regulatory compliance has not had a material effect on our results to date. We are not aware of any pending legislation that is likely to have a material adverse effect on our operations. See "—Legal Proceedings," "—Risk Factors—Our brass products contain lead, which may be replaced in the future" and "—Risk Factors—Certain of our products may not be in compliance with NSF standards, which could limit the ability of municipalities to buy our products".

Employees

        We employ approximately 5,400 people, of whom approximately 85% work in the United States. The hourly employees at our principal United States manufacturing plants and foundries in Albertville, El Monte, Aurora, Decatur, Dixon, Columbia, Chattanooga and Henderson are represented by unions,

11

as are the hourly employees at two of our four distribution centers. Our operations in Canada at St. Jerome and at Simcoe are also unionized. Also, in March 2005, workers at our Milton, Canada manufacturing facility voted to accept union representation, and a union contract will be negotiated over the course of the six months following the union vote.

        The contracts with our union employees at our four largest manufacturing facilities are timed to expire in different years: Columbia in April 2005 (although an agreement with a relatively small union at our Columbia facility expires in May 2007), Chattanooga in September 2006, Decatur in June 2007 and Albertville in September 2008. The contracts with our union employees in El Monte and Simcoe expire in July and November 2005, respectively, Dixon in March 2006, and Aurora and Henderson in August and December 2007, respectively.

        In addition, approximately 125 of our employees are represented by various unions at our British Columbia, Montreal, Bloomington, Bristol, Cincinnati, Taylor, Portland and University Park piping systems products facilities. In March 2005, we announced the closing of the Portland facility and the termination of the union agreement with the union represented there. This termination is not anticipated to have any material impact on our financial position or results of operations.

        We believe that relations with our employees, including those represented by unions, are good. The last major union strike was in October 1987.

Risk Factors

        Investors in our Company should consider the following factors that could impact our Company's future results of operations and financial condition.

We depend on a group of major distributors for a significant portion of our sales; any loss of these distributors could reduce our sales and continuing consolidation could cause price pressure.

        In 2004, approximately 38% of our sales were to our ten largest distributors, and approximately 31% of our sales were to our three largest distributors: Hughes Supply, Ferguson Enterprises and National Waterworks. Our business relationship with most of our major distributors branches may be terminated at the option of either party upon zero to 60 days' notice.

        Our reliance on these major distributors exposes us to:

•

the risk of changes in the business condition of our major distributors, and



•

the risk that the loss of a major distributor could adversely affect our results of operations.

        While our relationships with our ten largest distributors have been long-lasting, distributors in our industry have experienced significant consolidation in recent years, and we cannot assure you that our distributors will not be acquired by other distributors who buy products from our competitors. We also cannot assure you that, as consolidation among distributors continues, distributors will not be able to force us to lower our prices, which would have an adverse impact on our results of operations. Moreover, the loss of any of National Waterworks, Hughes Supply or Ferguson Enterprises as a distributor could have a material adverse effect on our results of operations.

Our business will be adversely affected by a downturn in government spending related to infrastructure upgrades, repairs and replacements, or in the cyclical residential or non-residential building markets.

        Our business is primarily dependent upon spending on water and wastewater infrastructure upgrades, repairs and replacement, new water and wastewater infrastructure spending (which is dependent upon residential construction) and spending on non-residential construction. Spending

12

growth in the infrastructure upgrades, repairs and replacement sector has slowed in recent years as state and local governments' budgets were negatively impacted by the downturn in the economy. We cannot assure you that economic conditions will continue to improve or that if they do, that state and local governments will address deferred infrastructure needs. Although the residential building market has experienced growth in recent years, we cannot assure that this growth will continue in the future. The residential and non-residential building markets are cyclical, and, historically, down cycles have typically lasted approximately four to six years. From 1987 to 1991, total housing starts declined 38.1% from peak to trough. The United States reached a record high in single family housing starts in 2004 and housing starts continue to remain strong. Non-residential construction has slowed since 2000, with a modest improvement in 2004, and we cannot predict whether conditions will continue to improve. Any significant decline in the residential or non-residential building markets or governmental spending on infrastructure could have a material adverse effect on our financial condition and results of operations.

Our brass products contain lead, which may be replaced in the future.

        Our brass products, which constituted approximately 8.5% of our sales in 2004, contain approximately 5.0% lead. Environmental advocacy groups, relying on standards established by California's Proposition 65, are seeking to eliminate or reduce the content of lead in some of these products, including water meters and valves, and to limit their sale in California. Some of our business units have entered into settlement agreements with these environmental advocacy groups that have required them to either modify some of these products or offer substitutes for them with respect to products sold in California. Modifications of or substitutions for our products to meet or conform with regulatory requirements will require incremental capital spending of up to $8.0 million in the next two years and will require us to purchase more expensive raw materials, and we may not be able to pass these costs on to our customers. Legislation to substantially restrict lead content in water products has been introduced in the United States Congress. If Congress adopts such legislation or if similar issues are raised in Congress in the future or in other jurisdictions or if these or other advocacy groups file suit against us under Proposition 65, our results of operations and financial condition could be adversely affected.

Certain of our products may not be in compliance with NSF standards, which could limit the ability of municipalities to buy our products.

        The National Sanitary Foundation ("NSF") is a non-profit entity that was contracted by the U.S. Environmental Protection Agency ("EPA") to promulgate standards for the water industry. NSF has issued NSF 61, which governs the leaching characteristics of valves and devices that are part of drinking water distribution networks, including certain of our products made from brass. In recent years, a growing majority of states have adopted, by statute or regulation, a requirement that water distribution systems utilize products that comply with NSF 61 and/or are certified as NSF 61 compliant. We, along with others in the industry, are engaged in the lengthy process of attempting to obtain certification of NSF 61 compliance for all of our relevant products. In 2004, our sales of brass products were $92.6 million, or 8.5% of our sales. Approximately 3,400 of the water infrastructure products we currently produce are made of brass. Approximately 85% of these water infrastructure brass products have been certified; and these represent approximately 70% of our water infrastructure brass product sales. In the event that some of our water infrastructure brass products are found not to be in compliance with NSF 61, those products may not be accepted by various municipalities or we may be forced to modify non-conforming products with substitute materials which may require increased cost, thereby adversely affecting profitability. In addition, if our competitors develop a complete line of NSF 61 compliant brass products before we do, we may be placed at a competitive disadvantage which may, in turn, adversely affect profitability.

13

Our industry is very competitive and some of our piping systems products are commodities.

        The domestic and international markets for flow control products are competitive. While there are only a few competitors for most of our product offerings, many of them are well-established companies with strong brand recognition. In particular, our malleable iron and cast iron pipe fitting products, which together comprised 9.0% of our sales in 2004, face competition from less expensive imports and our pipe nipple and hanger products and our pipe fittings and couplings products, which together comprised 25.5% of our sales in 2004, compete on the basis of price and are sold in fragmented markets with low barriers to entry, allowing less expensive domestic and foreign producers to gain market share and reduce our margins.

        In addition, the U.S. Department of Commerce has imposed anti-dumping duties on imported malleable and non-malleable iron fittings from China. We cannot assure you that these government agencies will continue the current duties on imported malleable and non-malleable iron fittings. If the duties for respondent companies, which range from 7.35% to 14.32% (111.36% for other producers/exporters) for malleable iron fittings and 6.34% to 7.08% (75.5% for other producers/exporters) for non-malleable iron fittings, are reduced or completely eliminated, we may be forced to reduce the prices of some of our products. An increase in foreign competition, a decrease in these duties or a strengthening in the U.S. dollar could have a material adverse effect on our financial condition and results of operations.

Our results have been, and may continue to be, adversely impacted by increases in raw material prices.

        Our products are made from several basic raw materials, including sand, resin, brass ingot, steel pipe and scrap steel and iron. We generally purchase raw materials at spot prices and do not hedge our exposure to price changes. Our business could be adversely affected by increases in the cost of our raw materials, as we may not be able to fully pass these costs on to our customers. Management estimates that raw materials and purchased components used in our manufacturing processes currently account for approximately 15%-17% of our cost of goods sold.

We may be unsuccessful in identifying or integrating suitable acquisitions, which could adversely affect our growth.

        Our growth strategy is built upon organic growth and on taking advantage of opportunities to acquire complementary businesses and services. This strategy depends on the availability of acquisition candidates with businesses that can be successfully integrated into our existing business and that will provide us with complementary manufacturing capabilities or products. However, we may be unable to identify targets that will be suitable for acquisition. In addition, if we identify a suitable acquisition candidate, our ability to successfully implement the acquisition will depend on a variety of factors, including our ability to finance the acquisition. Our ability to finance our acquisitions is subject to a number of factors, including the availability of adequate cash from operations or of acceptable financing terms and the terms of our debt instruments. In addition, there are many challenges to integrating acquired companies and businesses in our company, including eliminating redundant operations, facilities and systems, coordinating management and personnel, retaining key employees, managing different corporate cultures and achieving cost reductions and cross-selling opportunities. We cannot assure you that we will be able to meet these challenges in the future.

Businesses we have acquired or will acquire may not perform as expected.

        We may be adversely affected if businesses we have recently acquired or acquire in the future do not perform as expected. Acquired businesses may perform below expectations after the acquisition for various reasons, including legislative or regulatory changes that affect the areas in which a business specializes, the loss of key customers after the acquisition has closed, general economic factors that

14

affect a business in a direct way and the cultural incompatibility of an acquired management team with us. Any of these factors could adversely affect our results of operations.

We have a significant amount of debt which could adversely affect our financial health.

        As of September 30, 2004, we had $1,039.4 million of indebtedness. We may incur significant additional indebtedness from time to time. The level of our indebtedness could have important consequences, including:

•

making it more difficult for us to satisfy our obligations under our debt instruments;



•

limiting cash flow available for general corporate purposes, including capital expenditures and acquisitions, because a substantial portion of our cash flow from operations must be dedicated to servicing our debt;



•

limiting our ability to obtain additional debt financing in the future for working capital, capital expenditures or acquisitions;



•

limiting our flexibility to react to competitive and other changes in our industry and economic conditions generally; and



•

exposing us to risks inherent in interest rate fluctuations because a substantial portion of our borrowings is at variable rates of interest, which could result in higher interest expense in the event of increases in interest rates.

We will require a significant amount of cash to service our debt and our ability to generate cash depends on many factors beyond our control.

        Our ability to pay or to refinance our indebtedness will depend upon our future operating performance, which will be affected by general economic, financial, competitive, legislative, regulatory, business and other factors beyond our control. We cannot assure you that our business will generate sufficient cash flow from operations, that currently anticipated revenue growth and operating improvements will be realized or that future borrowings will be available to us in an amount sufficient to enable us to pay our indebtedness, or to fund our other liquidity needs. If we are unable to meet our debt service obligations or fund our other liquidity needs, we could attempt to restructure or refinance our indebtedness or seek additional equity capital. We cannot assure you that we will be able to accomplish those actions on satisfactory terms, if at all.

Restrictive covenants in our debt instruments may adversely affect us.

        Our debt instruments contain various covenants that limit our ability to engage in certain transactions. The senior credit facility and the indenture governing secured notes issued by our subsidiary, Mueller Group, also require the maintenance of specified financial ratios and the satisfaction of other financial condition tests. In addition, our debt instruments require us to provide regular financial information to our lenders and bondholders. Such requirements generally may be satisfied by our timely filing with the SEC of annual and quarterly reports under the Securities Exchange Act of 1934. Our ability to satisfy those financial ratios, tests or covenants can be affected by events beyond our control, and we cannot assure you that we will meet those tests. A breach of any of these covenants could result in a default under our debt instruments. As previously announced, we have been delayed in filing with the SEC our (and Mueller Group's) annual report on Form 10-K for our fiscal year ended September 30, 2004 and our (and Mueller Group's) quarterly report on Form 10-Q for our fiscal quarter ended January 1, 2005. Although we obtained a waiver under the senior credit facility allowing us to file these reports by March 31, 2005 and with respect to our restatement of prior period financial statements, there can be no assurance that similar waivers will be available in the future. We have not received a similar waiver under the indentures. If an event of default is not remedied after the delivery of notice of default and lapse of any relevant grace period, the holders of

15

our senior discount notes and of Mueller Group's senior and senior subordinated notes would be able to declare these notes immediately due and payable and the lenders under Mueller Group's senior credit facility would be able to declare an event of default. Upon the occurrence of an event of default under our senior credit facility, the lenders could elect to declare all amounts outstanding thereunder to be immediately due and payable and terminate all commitments to extend further credit. If we were unable to repay those amounts, the lenders could proceed against the collateral granted to them to secure the indebtedness under the senior credit facility and the secured notes. We have pledged substantially all of our assets, other than the assets of our foreign subsidiaries, as security under our senior credit facility and secured notes. If the lenders under the senior credit facility or noteholders of the notes accelerate the repayment of borrowings, we cannot assure you that we will have sufficient assets to repay our senior credit facility and our other indebtedness.

We are a holding company and may not have access to the cash flow and other assets of our subsidiaries.

        We are a holding company that has no operations of our own and derives all of our revenues and cash flow from our subsidiaries. The terms of the indentures governing Mueller Group's secured notes and subordinated notes and the senior credit facility significantly restrict Mueller Group and its subsidiaries from paying dividends and otherwise transferring assets to us. Furthermore, our subsidiaries are permitted under the terms of the senior credit facility and other indebtedness to incur additional indebtedness that may severely restrict or prohibit the making of distributions, the payment of dividends or the making of loans by such subsidiaries to us. A breach of those covenants would be a default under the applicable debt instrument that would permit the holders thereof to declare all amounts due thereunder immediately payable. As a result, we may not have access to our subsidiaries' cash flow to finance our cash needs.

Our business may be adversely impacted by work stoppages and other labor relations matters.

        We are subject to a risk of work stoppages and other labor relations matters because our hourly workforce is highly unionized. As of September 30, 2004, about 73% of our hourly workforce was represented by unions. These employees are represented by locals from approximately six different unions, including the Glass, Molders, Pottery, Plastics and Allied Workers International Union, which is our largest union. Two of our union contracts, both of which expire in April 2005, are currently being negotiated and all of our significant labor agreements will expire at various times through March 2009, at which time they must be renegotiated. Work stoppages for an extended period of time could have a material adverse effect on our business. Labor costs are a significant element of the total expenditures involved in our manufacturing process, and an increase in the costs of labor could therefore have a material adverse effect on our business. In addition, the freight companies who deliver our products to our distributors generally use unionized truck drivers, and we could also be adversely affected if our contractors face work stoppages or increased labor costs. For more information about our labor relations, see "—Employees."

We may be subject to product liability claims that could require us to make significant cash payments.

        We would be exposed to product liability claims in the event that the use of our products results, or is alleged to result, in bodily injury and/or property damage. We cannot assure you that we will not experience any material product liability losses in the future or that we will not incur significant costs to defend such claims. While we currently have product liability insurance, we cannot assure you that our product liability insurance coverage will be adequate for any liabilities that may ultimately be incurred or that it will continue to be available on terms acceptable to us. A successful claim brought against us in excess of our available insurance coverage or a requirement to participate in a product recall may have a materially adverse effect on our business.

        Under the terms of the August 1999 purchase agreement relating to the acquisition of our business from Tyco in August of 1999, we are indemnified by Tyco for all liabilities arising in connection with

16

our business with respect to products manufactured or sold prior to the closing of that transaction. See "Item 3.—Legal Proceedings." The indemnity survives forever and is not subject to any dollar limits. However, we may be responsible for these liabilities in the event that Tyco ever becomes financially unable to, or otherwise fails to comply with, the terms of the indemnity. In addition, Tyco's indemnity does not cover product liabilities to the extent caused by our products manufactured after that transaction. For more information about our potential product liabilities, see "Item 3.—Legal Proceedings."

We may be adversely affected by environmental, health and safety laws and regulations or liabilities.

        We are subject to various laws and regulations relating to the protection of the environment and human health and safety and must incur capital and other expenditures to comply with these requirements. Failure to comply with any environmental, health or safety requirements could result in the assessment of damages, or imposition of penalties, suspension of production, a required upgrade or change to equipment or processes or a cessation of operations at one or more of our facilities. Because these laws are complex, constantly changing and may be applied retroactively, we cannot assure you that these requirements, in particular as they change in the future, will not have a material adverse effect on our business, profitability and results of operations. In particular, we will be required to incur costs to comply with the EPA's National Emissions Standards for Hazardous Air Pollutants ("NESHAP") for iron and steel foundries and for our foundries' painting operations. These costs may be material. See "—Environmental Matters." In addition, we may be required to conduct investigations and perform remedial activities that could require us to incur material costs in the future. Our operations involve the use of hazardous substances and the disposal of hazardous wastes. We may incur costs to manage these substances and wastes and may be subject to claims for damage for personal injury, property damages or damage to natural resources.

        Under the terms of the August 1999 purchase agreement relating to the acquisition of our business from Tyco and our formation, we are indemnified by Tyco for all environmental liabilities arising in connection with our business and relating to actions occurring or conditions existing prior to the closing of that transaction, including certain asbestos litigation. See "Item 3.—Legal Proceedings." The indemnity survives forever and is not subject to any dollar limits. We however, may be responsible for these liabilities in the event that Tyco ever becomes financially unable to, or otherwise fails to comply with, the terms of the indemnity. In addition, Tyco's indemnity does not cover environmental liabilities to the extent caused by our company or the operation of our business after that transaction, nor does it cover environmental liabilities arising with respect to businesses or sites acquired after August 1999. For more information about our environmental compliance and potential environmental liabilities, see "—Environmental Matters" and "Item 3.—Legal Proceedings."

We depend on key personnel, many of whom do not have employment contracts.

        Our success depends to a significant extent on the continued services of our senior management and other members of management. We could be adversely affected if any of these persons were unwilling or unable to continue in our employ. While we have an employment agreement with Dale Smith, it expires in August 2005 (unless renewed), and, other than our employment agreements with George Bukuras and Darrell Jean, we do not have written employment agreements with other members of our senior management. See "Item 11.—Executive Compensation."

We need to improve our internal controls to comply with SEC reporting requirements; future public reporting obligations have put significant demands on our financial, operational and management resources.

        Prior to August 2004, we were a private company that did not file reports with the SEC, and our internal accounting controls do not currently meet all standards applicable to companies with publicly-traded securities. See "Item 9A—Controls and Procedures."

17

        We are currently taking additional steps to implement an internal control structure and procedures for financial reporting that would allow us to produce financial statements and related disclosure within the time periods and in the form required under the Exchange Act. In order to comply with these requirements, we have hired and plan to hire additional accounting and finance staff to implement new financial systems and procedures. We cannot assure you that we will be able to hire additional staff or implement appropriate procedures on a timely basis. Failure to hire such staff and implement such procedures could have an adverse effect on us.

Recently enacted and proposed changes in securities laws and regulations are likely to increase our costs.

        The Sarbanes-Oxley Act of 2002, as well as new rules subsequently implemented by the Securities and Exchange Commission and the Public Company Accounting Oversight Board, have required changes in the corporate governance and securities disclosure or compliance practices of public companies. We expect these new rules and regulations to further increase our legal and financial compliance costs and to make legal, accounting and administrative activities more time-consuming and costly. We also expect these new rules and regulations to make it more difficult and expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These new rules and regulations could also make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee, and executive officers. We cannot estimate the amount of additional costs we may incur or the timing of such costs.

We are controlled by principal stockholders whose interests may differ from your interests.

        Substantially all of the outstanding shares of our common stock are held by the DLJ Merchant Banking funds. As a result of their stock ownership and our stockholders agreement, the DLJ Merchant Banking funds control us and have the power to elect a majority of our directors, appoint new management and approve any action requiring the approval of the holders of common stock, including adopting amendments to our certificate of incorporation and approving acquisitions or sales of all or substantially all of our assets. The directors elected by the DLJ Merchant Banking funds have the ability to control decisions affecting our capital structure, including the issuance of additional capital stock, the implementation of stock repurchase programs and the declaration of dividends. The interests of our principal stockholders may conflict with your interests. The general partners of the DLJ Merchant Banking funds are affiliates or employees of Credit Suisse First Boston, acting through its Cayman Islands Branch, which is the arranger, administrative agent and a lender under our senior credit facility.

Item 2.    Properties

        The following chart describes our principal properties.

Water infrastructure products

Piping systems products

        Our leased properties have terms that expire between November 2005 and February 2009.

        We also operate four leased regional distribution centers in the United States for our piping systems products. See "Item 1.—Business—Distribution." The United States centers are located in University Park, Illinois; Sparks, Nevada; Bristol, Pennsylvania and Grand Prairie, Texas and have lease terms that expire between January 2006 and December 2013. In addition, we operate 24 smaller warehouses throughout the United States and Canada to support our piping systems product operations.

        We consider our plants and equipment to be modern and well-maintained and believe our plants will have sufficient capacity to meet our present and future needs. All of our domestic facilities, leases and leasehold interests are encumbered by liens securing our obligations under the senior credit facility and the Mueller Group secured notes.

19

Item 3.    Legal Proceedings

        We are involved in various legal proceedings which have arisen in the normal course of our operations, including the proceedings summarized below. Other than the litigation described below, we do not believe that any of our outstanding litigation would have a material adverse effect on our business, operations or prospects.

        In the Acquisition Agreement pursuant to which the DLJ Merchant Banking funds acquired Mueller in 1999, Tyco agreed to indemnify Mueller Water and its affiliates for all "Excluded Liabilities". Excluded Liabilities include, among other things, substantially all liabilities relating to the time prior to the closing of DLJMB's acquisition of Mueller. The indemnity survives indefinitely and is not subject to any deductibles or caps. However, we may be responsible for these liabilities in the event that Tyco ever becomes financially unable to, or otherwise fails to comply with, the terms of the indemnity. In addition, Tyco's indemnity does not cover environmental liabilities to the extent caused by our company or the operation of our business after the acquisition, nor does it cover environmental liabilities arising with respect to businesses or sites acquired after August 1999.

        Our Mueller Co. subsidiary and its subsidiary, James Jones Company, received notice in November 2002 that they may be named defendants in a case under Proposition 65, a California law that, among other things, requires companies doing business in California to avoid discharges of certain chemicals into drinking water. The law permits private parties to bring an action in the public interest against alleged violators, provided that plaintiffs must provide written notice to intended defendants at least 60 days prior to initiating litigation. Mueller Co. and James Jones Company have received the required statutory notice. The plaintiff alleges that the brass valves manufactured by the companies discharge lead into drinking water, in violation of Proposition 65. The plaintiff's current settlement demand would require the companies to cease manufacturing, marketing or distributing brass valves in California that discharge lead above certain threshold limits.

        The Company's subsidiary, James Jones Company, and its former parent company are defendants in a false claims lawsuit in which a former James Jones Company employee is suing on behalf of cities, water districts and municipalities. The employee alleges that the defendants sold allegedly non-conforming public water system parts to various government entities. The lawsuit seeks consequential damages, penalties and punitive damages. The Company's subsidiary, Mueller Co., which had also been named as a defendant, brought a summary judgment motion and was dismissed from this litigation in January 2004. On September 15, 2004, the trial court ruled against the intervention of approximately 30 municipalities that had failed to intervene within the time deadlines previously specified by the Court. The trial court also ruled that the majority of municipalities that had purchased James Jones products from contractors or distributors, were not in privity with the James Jones Company and were not entitled to punitive damages. Following the Court's ruling, the water districts and municipalities filed a new action against the James Jones Company, Mueller Co. and Watts (former parent company of James Jones Company), alleging fraud and intentional misrepresentation. This lawsuit is based on the same underlying facts as the false claims lawsuit. Any liability associated with these lawsuits is covered by the Tyco indemnity, and the defense is being paid for and conducted by Tyco.

        Four of our subsidiaries have been named as defendants in a small number of asbestos-related lawsuits. We do not believe these lawsuits, either individually or in the aggregate, are material to our financial position or results of operations. Any liability associated with these lawsuits is covered by the Tyco indemnity, and the defenses are currently being conducted by Tyco.

        On March 31, 2004, our Anvil International subsidiary entered into a consent order with the Georgia Department of Natural Resources regarding alleged hazardous waste violations at Anvil's former foundry facility in Statesboro, Georgia. Pursuant to the consent order, Anvil has agreed to pay a settlement amount of $100,000, comprised of a $50,000 monetary fine and $50,000 towards a

20

supplemental environmental project. Anvil has also agreed to perform various investigatory and remedial actions at the foundry and its landfill. While the ultimate investigatory and remedial costs are currently unknown, based on currently available information the total costs are estimated to be between $0.8 million and $1.0 million.

        Mueller Co. and its wholly owned subsidiary, Mueller International, Inc. (together, "Mueller"), sued a competitor, U.S. Pipe & Foundry Co. ("U.S. Pipe"), for, among other claims, infringement and dilution of Mueller's federally registered and common-law trade dress for fire hydrants. U.S. Pipe responded with counterclaims including claims of intentional interference with its business relations. Mueller succeeded in obtaining a preliminary injunction against U.S. Pipe for infringement of Mueller's federally registered trade dress. The parties entered into a partial settlement whereby U.S. Pipe agreed not to produce the offending fire hydrant or anything confusingly similar, and to dismiss all counterclaims. Mueller, in turn, dismissed its common-law trade dress claims while reserving the right to seek leave to add claims to the case relating to misuse of the Mueller trademark and unfair competition in association with the promotion of U.S. Pipe's new fire hydrant. The trial court denied Mueller's motion to add these claims. Mueller has appealed.

        In November 2003, Beck Manufacturing, a division of Anvil International, closed its manufacturing facility in Kearny, New Jersey and withdrew from the Teamsters Local 11 Pension Fund ("Teamsters" or "Fund"). Anvil has established an accrual of $0.2 million for any withdrawal liability. On July 19, 2004, the Fund Trustees issued notice to Anvil that pursuant to ERISA Sections 4202 and 4219(b)(1), Anvil owed approximately $1.2 million in withdrawal liability to the Fund. On October 5, 2004, Anvil sent notice to the Teamsters contesting the amount of the withdrawal liability. In February 2005, the Teamsters gave notice of their plan to appeal and pursue arbitration under the guidelines set out in the Teamsters Trust Agreement. Anvil intends to vigorously defend its position that a substantially lower withdrawal liability is appropriate.
