PART I

ITEM 1—BUSINESS

General

Huttig Building Products, Inc., a Delaware corporation incorporated in 1913, was founded in 1885 and is a leading domestic distributor of millwork, building materials and wood products used principally in new residential construction and in home improvement, remodeling and repair work. We purchase from leading manufacturers and distribute our products through 27 wholesale distribution centers serving 41 states. Our distribution centers sell principally to building materials dealers, national buying groups, home centers and industrial users, including makers of manufactured homes. For the year ended December 31, 2012, we generated net sales of $520.5 million.

We conduct our business through a two-step distribution model. This means we resell the products we purchase from manufacturers to our customers, who then sell the products to the final end users, who are typically professional builders and independent contractors engaged in residential construction and remodeling projects.

Our products fall into three categories: (i) millwork, which includes doors, windows, moulding, stair parts and columns, (ii) general building products, which include composite decking, connectors, fasteners, housewrap, roofing products and insulation, and (iii) wood products, which include engineered wood products, such as floor systems, as well as wood panels and lumber.

Doors and engineered wood products often require an intermediate value added service between the time the product leaves the manufacturer and before it is delivered to the final customer. We perform such services, on behalf of our customers, which include pre-hanging doors and cutting engineered wood products from standard lengths to job-specific requirements. In addition, with respect to the majority of our products, we have the capability to buy in bulk and disaggregate these large shipments to meet individual customer stocking requirements. For some products, we carry a depth and breadth of products that our customers cannot reasonably stock themselves. Our customers benefit from our business capabilities because they do not need to invest capital in door hanging facilities or cutting equipment, nor do they need to incur the costs associated with maintaining large inventories of products. Our size, broad geographic presence, extensive fleet and logistical capabilities enable us to purchase products in large volumes at favorable prices, stock a wide range of products for rapid delivery and manage inventory in a reliable, efficient manner.

We serve our customers, whether they are a local dealer or a national account, through our 27 wholesale distribution centers. Our broad geographic footprint enables us to work with our customers and suppliers to ensure that local inventory levels, merchandising, purchasing and pricing are tailored to the requirements of each market. Each distribution center also has access to our single-platform nationwide inventory management system. This provides the local manager with real-time inventory availability and pricing information. We support our distribution centers with credit and financial management, training and marketing programs and human resources expertise. We believe that these distribution capabilities and efficiencies offer us a competitive advantage as compared to those of many local and regional competitors.

In this Annual Report on Form 10-K, when we refer to “Huttig,” the “Company”, “we” or “us,” we mean Huttig Building Products, Inc. and its subsidiary and predecessors unless the context indicates otherwise.

Industry Characteristics and Trends

The residential building materials distribution industry is characterized by its substantial size, its highly fragmented ownership structure and an increasingly competitive environment. The industry can be broken into two categories: (i) new construction and (ii) home repair and remodeling.

Residential construction activity in both categories is closely linked to a variety of factors directly affected by general economic conditions, including employment levels, job and household formation, interest rates, housing prices, tax policy, availability of mortgage financing, prices of commodity wood and steel products,

immigration patterns, regional demographics and consumer confidence. We monitor a broad set of macroeconomic and regional indicators, including new housing starts and permit issuances, as indicators of our potential future sales volume.

The downturn in the residential construction market has been one of the most severe housing downturns in U.S. history. New housing activity in the United States increased in 2012 versus 2011; however, 2012 activity is still well below historical averages. Total new housing starts in the United States were at approximately 0.8 million in 2012 compared to 0.6 million in each of 2011 and 2010. Single family starts were 0.5 million, 0.4 million and 0.5 million in 2012, 2011 and 2010, respectively, based on data from the U.S. Census Bureau. According to the U.S. Census Bureau, total spending on new single family residential construction was $129 billion, $108 billion and $113 billion in 2012, 2011 and 2010, respectively.

The residential building materials distribution industry has undergone significant changes over the last three decades. Prior to the 1970s, residential building products were distributed almost exclusively by local dealers, such as lumberyards and hardware stores. These channels served both the retail consumer and the professional builder. Dealers generally purchased their products from wholesale distributors and sold building products directly to homeowners, contractors and homebuilders. In the late 1970s and 1980s, substantial changes began to occur in the retail distribution of building products. The introduction of the mass retail, big box format by The Home Depot and Lowe’s began to alter this distribution channel, particularly in metropolitan markets. They began displacing local dealers by selling a broad range of competitively priced building materials to the homeowner and small home improvement contractors. We generally do not compete with building products mass retailers such as The Home Depot and Lowe’s. Their business model for building products is primarily suited to sell products that require little or no differentiation with very high turn volumes. Conversely, a substantial portion of our product offering consists of products that typically require intermediate value-added handling and/or a large breadth of SKUs.

We service large local, regional and national independent building products dealers who in turn sell to contractors and professional builders. These large local, regional and national building products dealers, often referred to as “pro dealers,” continue to distribute a significant portion of the residential building materials sold in the United States. These pro dealers operate in an increasingly competitive environment. Consolidation among building products manufacturers favors distributors that can buy in bulk and break down large production runs to specific local requirements. In addition, increasing scale and sophistication among professional builders and contractors places a premium on pro dealers that can make a wide variety of building products readily available at competitive prices. In response to the increasingly competitive environment for building products, many pro dealers have either consolidated or formed buying groups in order to increase their purchasing power and/or service levels.

We believe the evolving characteristics of the residential building materials distribution industry, particularly the consolidation trend, favor companies like us that operate nationally and have significant infrastructure in place to accommodate the needs of customers across geographic regions. We are the only national distributor of millwork products. Because of our wide geographic presence, size, purchasing power, materials handling efficiencies and investment in millwork services, we believe we are well positioned to serve the needs of the consolidating pro dealer community.

Products

Our goal is to offer products that allow us to provide value to our customers, either by performing incremental services on the products before delivering them to customers, buying products in bulk and disaggregating them for individual customers or carrying a depth and breadth of products that customers cannot reasonably stock themselves at each location. Our products can be classified into three main categories:

-2-

The following table sets forth information regarding the percentage of our net sales from continuing operations represented by our principal product categories sold during each of the last three fiscal years. While the table below generally indicates the mix of our sales by product category, changes in the prices of commodity wood products and in unit volumes sold could affect our product mix on a year-to-year basis.

Customers

During 2012, we served over 4,200 customers, with one customer—Lumbermen’s Merchandising Corporation—accounting for 12% of our sales in 2012 and 11% of our sales in each of 2011 and 2010. This customer is a buying group representing multiple building material dealers. Building materials pro dealers represent our single largest customer group. Our top 10 customers accounted for approximately 37% of our total sales in 2012.

Within the pro dealer category, a large percentage of our sales are to national accounts, including buying groups. These are large pro dealers, or groups of pro dealers, that generally operate in more than one state or region. To a lesser extent, we also sell to the retail home centers. We believe that our size, which lets us purchase in bulk, achieve operating efficiencies, operate on a national scale and offer competitive pricing, makes us well suited to service the consolidating pro dealer community. Our sales to national accounts, including buying groups, were 40% of our total sales in each of 2012 and 2011 and 42% in 2010.

Organization

Huttig operates on a nationwide basis. Customer sales are conducted through 27 distribution centers serving 41 states. Administrative and executive management functions are centralized at our headquarters office located in St. Louis, Missouri. We believe that this structure permits us to be closer to our customers and serve them better, while being able to take advantage of certain efficiencies of scale that come from our size.

Headquarter functions include those activities that can be shared across our full distribution platform. These include financial management, information technology, human resources, legal, internal audit and investor relations along with small corporate operations, marketing and product management groups.

Operating responsibility resides with each distribution center’s general manager. The general manager assumes responsibility for daily operations, including sales, purchasing, personnel and logistics. Each distribution center generally maintains its own sales, warehouse and logistic personnel supported by a small administrative team.

-3-

Sales

Sales responsibility principally lies with general managers at our distribution centers. The sales function is generally divided into two channels: outside sales and inside sales. Our outside field representatives make on-site calls to local and regional customers. Our inside sales people generally receive telephone orders from customers and support our outside sales function. In addition, we maintain a national account sales team to serve national customers. Our outside sales force is generally compensated by a base salary plus commissions determined primarily on sales margin.

Distribution Strategy and Operations

We conduct our business through a two-step distribution model. This means that we resell the products that we purchase from manufacturers to our customers, who then sell the products to the final end user. Our principal customer is the pro dealer. To lesser extent, we also sell to the retail home centers and certain industrial users, such as makers of manufactured housing.

Despite our nationwide reach, the local distribution center is still a principal focus of our operations, and we tailor our business to meet local demand and customer needs. We customize product selection, inventory levels, service offerings and prices to meet local market requirements. We support this strategy through our single platform information technology system. This system provides each distribution center’s general manager real-time access to pricing, inventory availability and margin analysis. This system provides product information both for that location and across the entire Huttig network of distribution centers. More broadly, our sales force, in conjunction with our product management teams, works with our suppliers and customers to get the appropriate mix, quantity and pricing of products suited to each local market.

We purchased products from more than 800 different suppliers in 2012. We generally negotiate with our major suppliers on a national basis to leverage our total volume purchasing power, which we believe provides us with an advantage over our locally based competitors. The majority of our purchases are made from suppliers that offer payment discounts and volume related incentive programs. Although we generally do not have exclusive distribution rights for our key products and we do not have long-term contracts with many of our suppliers, we believe our national footprint, buying power and distribution network make us an attractive distributor for many manufacturers. Moreover, we have long-standing relationships with many of our key suppliers.

We regularly evaluate opportunities to introduce new products. This is primarily driven by customer demand or market requirements. We have found that customers generally welcome a greater breadth of product offering as it can improve their purchasing and operating efficiencies by providing for “one stop” shopping. Similarly, selectively broadening our product offering enables us to drive additional products through our distribution system, thereby increasing the efficiency of our operations by better utilizing our existing infrastructure.

We focus on selling respected, brand name products. We believe that brand awareness is an increasingly important factor in building products purchasing decisions. We generally benefit from the quality levels, marketing initiatives and product support provided by manufacturers of branded products. We also benefit by being associated with the positive attributes that customers typically equate with branded products.

Competition

We compete with many local and regional building product distributors and, in certain markets and product categories, with national building product distributors. In certain markets, we also compete with national building materials suppliers with national distribution capabilities. We distribute products for some manufacturers that also engage in direct sales.

-4-

The principal factors on which we compete are pricing and availability of product, service and delivery capabilities, ability to assist with problem solving, customer relationships, geographic coverage and breadth of product offerings.

Our size and geographic coverage are advantageous in obtaining and retaining distribution rights for brand name products. Our size also permits us to attract experienced sales and service personnel and gives us the resources to provide company-wide sales, product and service training programs. By working closely with our customers and suppliers and utilizing our single information technology platform, we believe our branches are well positioned to maintain appropriate inventory levels and to deliver completed orders on time.

Seasonality, Market Conditions and Working Capital

Various cyclical and seasonal factors, such as general economic conditions and weather, historically have caused our results of operations to fluctuate from period to period. Our size, extensive nationwide operating model, and the geographic diversity of our distribution centers to some extent mitigate our exposure to these cyclical and seasonal factors. These factors include levels of new construction, home improvement and remodeling activity, weather, interest rates and other local, regional and national economic conditions.

During the past several years, our results of operations have been adversely affected by the severe downturn in new housing activity in the United States. Even with a 28% increase in 2012, total housing starts were still well below historical averages. Based on the current level of housing activity and industry forecasts, we expect the increase in new housing activity could continue into 2013 but still remain below historical averages.

We anticipate that fluctuations from period to period will continue in the future. Our first and fourth quarters are generally adversely affected by winter weather patterns in the Northeast, Midwest and Northwest, which typically result from seasonal decreases in levels of construction activity in these areas. Because much of our overhead and expenses remain relatively fixed throughout the year, our operating profits also tend to be lower during the first and fourth quarters. In addition, other weather patterns, such as hurricane season in the Southeast region of the United States during the third and fourth quarters, can have an adverse impact on our results in a particular period.

We depend on cash flow from operating activities and funds available under our secured credit facility to finance seasonal working capital needs, capital expenditures and any acquisitions that we may undertake. We typically generate cash from working capital reductions in the fourth quarter of the year and build working capital during the first quarter in preparation for our second and third quarters. Our working capital requirements are generally greatest in the second and third quarters, reflecting the seasonal nature of our business. The second and third quarters are also typically our strongest operating quarters, largely due to more favorable weather throughout many of our markets compared to the first and fourth quarters. We maintain significant inventories to meet the rapid delivery requirements of our customers and to enable us to obtain favorable pricing, delivery and service terms with our suppliers. At December 31, 2012 and 2011, inventories and accounts receivable in the aggregate constituted approximately 71% and 67% of our total assets, respectively. We closely monitor operating expenses and inventory levels during seasonally affected periods and, to the extent possible, manage variable operating costs to minimize the seasonal effects on our profitability.

Credit

Huttig’s corporate management establishes an overall credit policy for sales to customers and then delegates responsibility for most credit decisions to regional credit personnel. Our credit policies, together with careful monitoring of customer balances, have resulted in bad debt expense of approximately 0.1% of net sales in 2012, 2011, and 2010. Approximately 98% of our sales in 2012 were to customers to whom we had provided credit for those sales.

-5-

Backlog

Our customers generally order products on an as-needed basis. As a result, virtually all product shipments in a given fiscal quarter result from orders received in that quarter. Consequently, order backlog represents only a very small percentage of the product sales that we anticipate in a given quarter and is not necessarily indicative of actual sales for any future period.

Tradenames

Historically, Huttig has operated under various trade names in the markets we serve, retaining the names of acquired businesses for a period of time to preserve local identification. To capitalize on our national presence, all of our distribution centers operate under the primary trade name “Huttig Building Products.” Huttig has no material patents, trademarks, licenses, franchises or concessions other than the Huttig Building Products^® name and logo, which are registered trademarks.

Environmental Matters

We are subject to federal, state and local environmental protection laws and regulations. We believe that we are in material compliance, or are taking action aimed at assuring material compliance, with applicable environmental protection laws and regulations. However, there can be no assurance that future environmental liabilities will not have a material adverse effect on our financial condition or results of operations.

We have been identified as a potentially responsible party in connection with the cleanup of contamination at our formerly owned property in Montana. See Part I, Item 3—“Legal Proceedings.”

In addition, some of our current and former distribution centers are located in areas of current or former industrial activity where environmental contamination may have occurred, and for which we, among others, could be held responsible. We currently believe that there are no material environmental liabilities at any of our distribution center locations.

Employees

As of December 31, 2012, we employed over 900 persons, of which approximately 13% were represented by eight unions. We have not experienced any significant strikes or other work interruptions in recent years and have maintained generally favorable relations with our employees. The Company has three union contracts which will require negotiations in 2013. See Item 1A-“Risk Factors.”

ITEM 1A—RISK FACTORS

In addition to the other information contained in this Form 10-K, the following risk factors should be considered carefully in evaluating the Company’s business. The Company’s business, financial condition or results of operations could be materially adversely affected by any of these risks. Please note that additional risks not presently known to the Company or that the Company currently deems immaterial may also impair its business and operations.

The homebuilding industry is in a prolonged significant downturn and any further downturn or sustained continuation of the current downturn will continue to materially affect our business, liquidity and operating results.

The downturn in the residential construction market has been one of the most severe housing downturns in U.S. history. High unemployment, tighter lending standards and general economic uncertainty, have contributed to a level of housing starts well below historical levels over the past several years.

Our sales depend heavily on the strength of national and local new residential construction and home improvement and remodeling markets. The strength of these markets depends on new housing starts and residential renovation projects, which are a function of many factors beyond our control. Some of these factors include general economic conditions, employment levels, job and household formation, interest rates, housing prices, tax policy, availability of mortgage financing, prices of commodity wood and steel products, immigration patterns, regional demographics and consumer confidence.

Our results of operations have been adversely affected by the severe downturn in new housing activity in the United States. Although housing starts increased in 2012, they were still well below historical levels. We expect the level of new housing activity to continue to be well below historical averages in 2013 which could adversely affect our operating results. A prolonged continuation of the current downturn or any further downturns in the markets that we serve or in the economy in general could have a material adverse effect on our operating results, liquidity and financial condition, including but not limited to our ability to comply with the financial covenant under the credit facility and the valuation of our goodwill. Reduced levels of construction activity may result in continued intense price competition among building materials suppliers, which may adversely affect our gross margins. We cannot provide assurance that our responses to the downturn or the government’s attempts to address the troubles in the economy will be successful.

The industry in which we compete is highly cyclical, and any downturn resulting in lower demand or increased supply would have a materially adverse impact on our financial results.

The building products distribution industry is subject to cyclical market pressures caused by a number of factors that are out of our control, such as general economic and political conditions, inventory levels of new and existing homes for sale, levels of new construction, home improvement and remodeling activity, interest rates and population growth. To the extent that cyclical market factors adversely impact overall demand for building products or the prices that we can charge for our products, our net sales and margins would likely decline in the same time frame as the cyclical downturn occurs. Because much of our overhead and expense is relatively fixed in nature, a decrease in sales and margin generally has a significant adverse impact on our results of operations. For example, during the past several years, our results of operations have been adversely affected by the severe downturn in new housing activity in the United States. Also, to the extent our customers experience downturns in business, our ability to collect our receivables could be adversely affected. Finally, the unpredictable nature of the cyclical market factors that impact our industry make it difficult to forecast our operating results.

If we are unable to meet the financial covenant under our credit facility, the lenders could elect to accelerate the repayment of the outstanding balance and, in that event, we would be forced to seek alternative sources of financing.

We are party to a $120.0 million asset based senior secured revolving credit facility which contains a minimum fixed charge coverage ratio that is tested if our excess borrowing availability, as defined in the facility, reaches a range of $10.0 million to $15.0 million depending on our borrowing base at the time of testing. At the

-7-

time of testing, our fixed charge coverage ratio would need to exceed 1.25:1.00. As of December 31, 2012, we would not have met the minimum fixed charge coverage ratio, and we believe we will not achieve sufficient financial results necessary to satisfy this covenant if it were required to be tested. If we were unable to maintain excess borrowing availability of more than the range of $10.0 million to $15.0 million and were also unable to comply with this financial covenant, our lenders would have the right, but not the obligation, to terminate the loan commitments and accelerate the repayment of the entire amount outstanding under the credit facility. The lenders also could foreclose on our assets that secure our credit facility. In that event, we would be forced to seek alternative sources of financing, which may not be available on terms acceptable to us, or at all.

Our excess borrowing availability at December 31, 2012 and February 15, 2013 was $24.3 million and $36.6 million, respectively, which exceeded the $10.4 million and $12.3 million required, respectively on those dates. Our credit facility matures in December 2017.

Compliance with the restrictions and the financial covenant under our credit agreement will likely limit, at least in the near term, the amount available to us for borrowing under that facility and may limit management’s discretion with respect to certain business matters.

The borrowings under our credit agreement are collateralized by substantially all of the Company’s assets, including accounts receivable, inventory and property and equipment, and we are subject to certain operating limitations commonly applicable to a loan of this type, which, among other things, place limitations on indebtedness, liens, investments, mergers and acquisitions, dispositions of assets, cash dividends, stock repurchases and transactions with affiliates. A minimum fixed charge coverage ratio must be tested on a pro forma basis prior to consummation of certain significant business transactions outside the Company’s ordinary course of business. These restrictions may limit management’s ability to operate our business in accordance with management’s discretion, which could limit our ability to pursue certain strategic objectives.

A significant portion of our sales are concentrated with a relatively small number of customers. A loss of one or more of these customers would have material adverse effect on our operating results, cash flow and liquidity.

In 2012, our top ten customers represented 37% of our sales, with one customer accounting for 12% of our sales. This customer is a buying group for multiple building material dealers. Although we believe that our relationships with our customers are strong, the loss of one or more of these customers could have a material adverse effect on our operating results, cash flow and liquidity.

A significant portion of our sales are on credit to our customers. Material changes in their creditworthiness or our inability to forecast deterioration in their credit position could have a material adverse effect on our operating results, cash flow and liquidity.

The majority of our sales are on account where we provide credit to our customers. In 2012, bad debt expense to total net sales was approximately 0.1%. Our customers are generally susceptible to the same economic business risks as we are. Furthermore, we may not necessarily be aware of any deterioration in their financial position. If our customers’ financial position becomes impaired, it could have a significant adverse impact on our bad debt exposure and could have a material adverse effect on our operating results, cash flow and liquidity.

Fluctuation in prices of commodity wood and steel products that we buy and then resell may have a significant impact on our results of operations.

Changes in wood and steel commodity prices between the time we buy these products and the time we resell them have occurred in the past, and we expect fluctuations to occur again in the future. Such changes can adversely affect the gross margins that we realize on the resale of the products. We may be unable to manage these fluctuations effectively or minimize any negative impact of these changes on our financial condition and results of operations.

-8-

The termination of key supplier relationships may have an immediate material adverse effect on our financial condition and results of operations.

We distribute building materials that we purchase from a number of major suppliers. As is customary in our industry, most of our relationships with these suppliers are terminable without cause on short notice. Although we believe that relationships with our existing suppliers are strong and that in most cases we would have access to similar products from competing suppliers, the termination of key supplier relationships or any other disruption in our sources of supply, particularly of our most commonly sold items, could have a material adverse effect on our financial condition and results of operations. Supply shortages resulting from unanticipated demand or production difficulties could occur from time to time and could have a material adverse effect on our financial condition and results of operations.

The building materials distribution industry is fragmented and competitive, and we may not be able to compete successfully with some of our existing competitors or new entrants in the markets we serve.

The building materials distribution industry is fragmented and competitive. Our competition varies by product line, customer classification and geographic market. The principal competitive factors in our industry are:

Also, financial stability is important to manufacturers and customers in choosing distributors for their products.

We compete with many local, regional and, in some markets and product categories, national building materials distributors and dealers. In addition, some product manufacturers sell and distribute their products directly to our customers, and the volume of such direct sales could increase in the future. Additionally, manufacturers of products distributed by us may elect to sell and distribute directly to our customers in the future or enter into exclusive supplier arrangements with other two-step distributors. In addition, home center retailers, which have historically concentrated their sales efforts on retail consumers and small contractors, may intensify their marketing efforts to larger contractors and homebuilders. Some of our competitors have greater financial and other resources and may be able to withstand sales or price decreases better than we can. We also expect to continue to face competition from new market entrants. We may be unable to continue to compete effectively with these existing or new competitors, which could have a material adverse effect on our financial condition and results of operations.

We have retained accident and claims risk under our insurance programs. Significant claims, and/or our ability to accurately estimate the liability for these claims could have a material adverse effect on our operating results.

We retain a portion of the accident and claims risk under vehicle liability, workers’ compensation, medical and other insurance programs. We have multiple claims of various sizes and forecast the number of claims in determining the portion of accident risk we are willing to self insure. We base loss accruals on our best estimate of the cost of resolution of these matters and adjust them periodically as circumstances change. Due to limitations inherent in the estimation process, our estimates may change. Changes in the actual number of large claims or changes in the estimates of these accruals may have a material adverse affect on our results of operations in any such period.

-9-

In addition, our insurance underwriters require collateral, generally in the form of letters of credit, which reduce our borrowing availability under our senior secured credit facility. Changes in the actual number of large claims could increase our collateral requirements and reduce our borrowing availability under our credit facility.

Federal and state transportation regulations, as well as increases in the cost of fuel, could impose substantial costs on us, which could adversely affect our results of operations.

We use our own fleet of approximately 150 tractors, 10 trucks and 330 trailers to service customers throughout the United States. The U.S. Department of Transportation, or DOT, regulates our operations, and we are subject to safety requirements prescribed by the DOT. Vehicle dimensions and driver hours of service also are subject to both federal and state regulation. More restrictive limitations on vehicle weight and size, trailer length and configuration, or driver hours of service could increase our costs.

In addition, distributors are inherently dependent upon energy to operate and, therefore, are impacted by changes in diesel fuel prices. The cost of fuel has reached historically high levels during portions of the last three years, is largely unpredictable and has a significant impact on the Company’s results of operations. Fuel availability, as well as pricing, is also impacted by political and economic factors. It is difficult to predict the future availability of fuel due to the following factors, among others: dependency on foreign imports of crude oil and the potential for hostilities or other conflicts in oil producing areas; limited refining capacity; and the possibility of changes in governmental policies on fuel production, transportation and marketing. Significant disruptions in the supply of fuel could have a negative impact on fuel prices and thus the Company’s operations and results of operations.

Our failure to attract and retain key personnel could have a material adverse effect on our future success.

Our future success depends, to a significant extent, upon the continued service of our executive officers and other key management and sales personnel and on our ability to continue to attract, retain and motivate qualified personnel. The loss of the services of one or more key employees or our failure to attract, retain and motivate qualified personnel could have a material adverse effect on our business.

A number of our employees are unionized, and any work stoppages by our unionized employees may have a material adverse effect on our results of operations.

Approximately 13% of our employees are represented by labor unions as of December 31, 2012. As of December 31, 2012, we had eight collective bargaining agreements. The Company has three union contracts which will require negotiations in 2013. We may become subject to significant wage increases or additional work rules imposed by future agreements with labor unions representing our employees. Any such cost increases or new work rule implementation could increase our operating expenses to a material extent. In addition, although we have not experienced any strikes or other significant work interruptions in recent years and have maintained generally favorable relations with our employees, no assurance can be given that there will not be any work stoppages or other labor disturbances in the future, which could adversely impact our financial results.

Our unionized employees generally participate in certain multi-employer pension plans and funding requirements for these plans, particularly underfunded plans, may have a material adverse effect on our results of operations.

We participate in various multi-employer pension plans. Some of these multi-employer plans may be underfunded at any point in time. While the underfunded status may be cured in the normal course of plan management, a significant obligation may be created which could have a material adverse effect on our operations or could impact our decision to close or consolidate certain operating locations.

We face the risks that product liability claims and other legal proceedings relating to the products we distribute may adversely affect our business and results of operations.

As is the case with other companies in our industry, even though our suppliers generally warrant the products we sell, we face the risk of product liability and other claims of the type that are typical to our industry in the event that the use of products that we have distributed causes other damages. Product liability claims in the future, regardless of their ultimate outcome and whether or not covered under our insurance policies or indemnified by our suppliers, could result in costly litigation and have a material adverse effect on our business and results of operations.

We may acquire other businesses, and, if we do, we may be unable to integrate them with our business, which may impair our financial performance.

If we find appropriate opportunities, we may acquire businesses that we believe provide strategic opportunities. If we acquire a business, the process of integration may produce unforeseen operating difficulties and expenditures and may absorb significant attention of our management that would otherwise be available for the ongoing development of our business. If we make future acquisitions, we may issue shares of stock that dilute other stockholders, expend cash, incur debt, assume contingent liabilities or create additional expenses relating to amortizing intangible assets with estimated useful lives, any of which might harm our business, financial condition or results of operations.

We face risks of incurring significant costs to comply with environmental regulations.

We are subject to federal, state and local environmental protection laws and regulations and may have to incur significant costs to comply with these laws and regulations in the future. We have been identified as a potentially responsible party in connection with the cleanup of contamination at a formerly owned property in Montana, where we are voluntarily remediating the property under the oversight of the Montana Department of Environmental Quality (Montana DEQ). Until the Montana DEQ selects and orders us to implement a final remedy, we can give no assurance as to the scope or cost to us of any final remediation order. In addition, some of our current and former distribution centers are located in areas of current or former industrial activity where environmental contamination may have occurred, and for which we, among others, could be held responsible. As a result, we may incur material environmental liabilities in the future with respect to our current or former distribution center locations.

Goodwill is a significant portion of our total assets and is tested for impairment at least annually, which could result in a material non-cash write-down of goodwill.

Goodwill is subject to impairment tests at least annually and between annual tests in certain circumstances. During 2012 and 2011, we recorded non-cash impairment charges of goodwill of $1.9 million and $0.4 million, respectively, primarily related to a reduction in fair value of one reporting unit in 2012 and two reporting units in 2011, as a result of the continuing downturn in the residential construction and real estate markets. At December 31, 2012, we had goodwill assets of $6.3 million. We may be required to incur additional non-cash impairment charges in the future that could have a material adverse effect on our operating results.

Our financial results reflect the seasonal nature of our operations.

Our first quarter and our fourth quarter revenues are typically adversely affected by winter construction cycles and weather patterns in colder climates as the level of activity in the new construction and home improvement markets decreases. Because much of our overhead and expense remains relatively fixed throughout the year, our operating profits also tend to be lower during the first and fourth quarters. In addition, other weather patterns, such as hurricane season in the Southeast region of the United States during the third and fourth quarters, can have an adverse impact on our profits in a particular period.

ITEM 2—PROPERTIES

Our corporate headquarters is located at 555 Maryville University Drive, Suite 400, St. Louis, Missouri 63141, in leased facilities. We own 13 of our distribution centers and lease the balance. Warehouse space at distribution centers aggregated to approximately 3.0 million square feet as of December 31, 2012. Distribution centers range in size from 21,100 square feet to 260,000 square feet. The types of facilities at these centers vary by location, from traditional wholesale distribution warehouses to facilities with broad product offerings and capabilities for a wide range of value added services such as pre-hung door operations. We believe that our locations are well maintained and adequate for their purposes.

ITEM 3—LEGAL PROCEEDINGS

We are involved in various claims and litigation arising principally in the ordinary course of business. We believe that the disposition of these matters will not have a material adverse effect on our business or our financial condition.

We are subject to federal, state and local environmental protection laws and regulations. We believe that we are in compliance, or are taking action aimed at assuring compliance, with applicable environmental protection laws and regulations. However, there can be no assurance that future environmental liabilities will not have a material adverse effect on our financial condition or results or operations.

Environmental Matters

In 1995, Huttig was identified as a potentially responsible party in connection with the clean up of contamination at a formerly owned property in Montana that was used for the manufacture of wood windows. We are voluntarily remediating this property under the oversight of and in cooperation with the Montana Department of Environmental Quality (Montana DEQ) and are complying with a 1995 unilateral administrative order of the Montana DEQ to complete a remedial investigation and feasibility study. The remedial investigation was completed and approved in 1998 by the Montana DEQ, which has issued its final risk assessment of this property. In March 2003, the Montana DEQ approved Huttig’s work plan for conducting a feasibility study to evaluate alternatives for cleanup. In July 2004, we submitted the feasibility study report, which evaluated several potential remedies, including continuation and enhancement of remedial measures already in place and operating. We also submitted plans for testing a newer technology that could effectively remediate the site. The Montana DEQ approved these plans and a pilot test of the remediation technology was completed in July 2007. In conjunction with the Montana DEQ, Huttig is performing additional testing at this site. After evaluating the results of the additional testing, the Montana DEQ will provide additional comments on the feasibility study report and its recommended remedy, and then will select a final remedy, publish a record of decision and negotiate with Huttig for an administrative order of consent on the implementation of the final remedy. We spent less than $0.5 million, $0.5 million, and $0.2 million on remediation costs at this site in each of the years ended December 31, 2012, 2011 and 2010, respectively. The annual level of future remediation expenditures is difficult to estimate because of the uncertainty relating to the final remedy to be selected by the Montana DEQ. As of December 31, 2012, we have accrued $0.6 million for future costs of remediating this site, which management believes represents a reasonable estimate based on current facts and circumstances and the currently expected costs of remediation. Until the Montana DEQ selects a final remedy, however, management cannot estimate the top of the range of loss or cost to Huttig of the final remediation order. As a result, we may incur material adverse effect on the consolidated financial statements in the future with respect to this property.

In addition, some of our current and former distribution centers are located in areas of current or former industrial activity where environmental contamination may have occurred, and for which we, among others, could be held responsible. We currently believe that there are no material environmental liabilities at any of our distribution center locations.

ITEM 7—MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Huttig is a distributor of building materials used principally in new residential construction and in home improvement, remodeling and repair work. We distribute our products through 27 distribution centers serving 41 states and sell primarily to building materials dealers, national buying groups, home centers and industrial users, including makers of manufactured homes. Our products fall into three categories: (i) millwork, which includes doors, windows, moulding, stair parts and columns, (ii) general building products, which include composite decking, connectors, fasteners, housewrap, roofing products and insulation, and (iii) wood products, which include engineered wood products, such as floor systems, as well as wood panels and lumber.

Industry Conditions

The downturn in the residential construction market has been one of the most severe housing downturns in U.S. history. Our sales depend heavily on the strength of local and national new residential construction, home improvement and remodeling markets. During the past several years, our results of operations have been adversely affected by the severe downturn in new housing activity in the United States. Even with a 28% increase in 2012, total housing starts were still well below historical averages. Based on the current level of housing activity and industry forecasts, we expect the increase in new housing activity could continue into 2013 but still remain below historical averages.

In reaction to the housing downturn, the Company has been restructuring its operations since the second quarter of 2006. Since then, the Company closed, consolidated or sold 20 distribution centers. Additionally, the Company reduced its workforce by approximately 1,300 employees and had over 900 employees at the end of 2012. These actions, along with other cost reduction efforts, are primarily responsible for an approximate $110 million reduction in operating expenses from 2006 to 2012.

Various factors historically have caused our results of operations to fluctuate from period to period. These factors include levels of construction, home improvement and remodeling activity, weather, prices of commodity wood and steel products, interest rates, competitive pressures, availability of credit and other local, regional, national and economic conditions. Many of these factors are cyclical or seasonal in nature. We anticipate that further fluctuations in operating results from period to period will continue in the future. Our first quarter and fourth quarter are generally adversely affected by winter weather patterns in the Midwest and Northeast, which typically result in seasonal decreases in levels of construction activity in these areas. Because much of our overhead and expenses remain relatively fixed throughout the year, our operating profits tend to be lower during the first and fourth quarters.

We believe we have the product offerings, distribution channel, personnel, systems infrastructure and financial and competitive resources necessary for continued operations. Our future revenues, costs and profitability, however, are all likely to be influenced by a number of risks and uncertainties, including those in Item 1A—RISK FACTORS.

Critical Accounting Policies

We prepare our consolidated financial statements in accordance with U.S. generally accepted accounting principles, which require management to make estimates and assumptions. Management bases these estimates and assumptions on historical results and known trends as well as management forecasts. Actual results could differ from these estimates and assumptions.

Accounts Receivable—Trade accounts receivable consist of amounts owed for orders shipped to customers and are stated net of an allowance for doubtful accounts. Huttig’s corporate management establishes an overall credit policy for sales to customers and delegates responsibility for most credit decisions to regional credit

-16-

personnel. The allowance for doubtful accounts is determined based on a number of factors including when customer accounts exceed 90 days past due and specific customer account reviews. Our credit policies, together with careful monitoring of customer balances, have resulted in bad debt expense of approximately 0.1% of net sales in 2012, 2011 and 2010. Due to continued low levels in new housing activity, it is possible that our bad debt expense could increase as our customers experience greater financial difficulties.

Inventory—Inventories are valued at the lower of cost or market. We utilize the LIFO cost method to value the majority of our inventories. We review inventories on hand and record a provision for slow-moving and obsolete inventory based on historical and expected sales.

Valuation of Goodwill and Other Long-Lived Assets—We test the carrying value of our goodwill at each reporting unit for impairment on an annual basis and between annual tests in certain circumstances when there are indicators of potential impairment. The carrying value of goodwill is considered impaired when a reporting unit’s fair value is less than its carrying value. In that event, goodwill impairment is recognized to the extent recorded goodwill exceeds the implied fair value of that goodwill. Circumstances that can lead to interim goodwill testing include significant negative variances from forecasted sales or operating profits or changes in other circumstances that indicate the carrying amount of goodwill may not be recoverable. We utilize a discounted cash flows model to estimate fair value of a reporting unit. In our estimate of fair value of a reporting unit, the following significant assumptions, and changes therein, are considered:

At December 31, 2012, the Company had $6.3 million of goodwill recorded across 14 reporting units. Significant changes in our assumptions and the related projected cash flows utilized in calculating the reporting unit’s fair value could result in future goodwill impairment related to any of our reporting units. The Company experienced lower than anticipated sales trends and operating income at one reporting unit. After performing the first step of the impairment test, we determined the carrying amounts of goodwill in our one reporting unit exceeded fair value. As a result, we performed the second step and determined that the goodwill was impaired by approximately $1.9 million. In 2011, the Company recorded goodwill impairment of $0.4 million related to the reduction in fair value of two reporting units.

We test the carrying value of other long-lived assets, including intangible and other tangible assets, for impairment when events and circumstances warrant such review. The carrying value of long-lived assets is considered impaired when the anticipated undiscounted cash flows from such assets are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset.

Contingencies—We accrue expenses when it is probable that an asset has been impaired or a liability has been incurred and we can reasonably estimate the expense. Contingencies for which we have made accruals include environmental, product liability and certain other legal matters. It is possible that future results of operations for any particular quarter or annual period and our financial condition could be materially affected by changes in assumptions or other circumstances related to these matters. We accrue an estimate of the cost of resolution of these matters and make adjustments to the amounts accrued as circumstances change.

-17-

Self-Insurance—It is our policy to self-insure, up to certain limits, traditional risks including workers’ compensation, comprehensive general liability, physical loss to property and auto liability. We are also self-insured, up to certain limits, for certain other insurable risks, including the majority of our medical benefit plans. Insurance coverage is maintained for catastrophic property and casualty exposures as well as those risks required to be insured by law or contract. A provision for self-insured claims, based on our estimate of the aggregate liability for claims incurred, is revised and recorded quarterly. The estimates are derived from both internal and external sources, including but not limited to actuarial type estimates, claims incurred, the probability of losses and historical settlement experience. Our estimates are subject to uncertainty from various sources, including, among others, changes in claim reporting patterns, claim settlement patterns, judicial decisions, legislation and economic conditions. Although we believe our estimates are reasonable, significant differences related to the items noted above could materially affect our self-insurance obligations, future expense and cash flow.

Income Taxes— We operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues, which may require an extended period of time to resolve. We regularly review our potential tax liabilities for tax years subject to audit. Changes in our tax liability may occur in the future as our assessment changes based on the progress of tax examinations in various jurisdictions and/or changes in tax regulations. In management’s opinion, adequate provisions for income taxes have been made for all years presented.

Deferred tax assets and liabilities are recognized for the future tax benefits or liabilities attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates would be recognized in income in the period that includes the enactment date. We regularly review our deferred tax assets for recoverability and establish a valuation allowance when we believe that such assets may not be recovered, taking into consideration historical operating results, expectations of future earnings, changes in operations, the expected timing of the reversal of existing temporary differences and available tax planning strategies. Currently, our deferred tax liabilities, which reverse in the same periods and jurisdictions as our deferred tax assets, enable us to partially utilize the deferred tax assets at December 31, 2012, without relying on any projections of future pre-tax income. The balance of these deferred tax assets are covered by a valuation allowance.

Results of Operations

Fiscal 2012 Compared to Fiscal 2011

Continuing Operations

Net sales from continuing operations were $520.5 million in 2012, which were $41.8 million, or approximately 9%, higher than 2011. This increase is primarily due to higher levels of new residential construction activity along with modest increases in repair and remodel spend, partially offset by a decline in certain storm driven roofing sales.

Sales in the major product categories changed as follows in 2012 from 2011: millwork sales increased 13% to $242.3 million, building product sales increased 4% to $219.4 million, and wood products increased 10% to $58.8 million with a 23% increase in sales of engineered wood products and a 7% increase in sales of other wood products. The increase in building product sales was partially offset by the decrease in our roofing business, which is partially storm driven. Fluctuations across product categories can occur based on new product incentives, promotions, changes in product lines, commodity pricing and weather, among other things.

Gross margin increased approximately 13% to $100.1 million, or 19.2% of sales, in 2012 as compared to $88.6 million, or 18.5% of sales, in 2011. The higher margin percentage in 2012 reflects changes in the product mix coupled with a concerted effort to increase margins. In 2012 and 2011, gross margins continued to be negatively impacted by competitive pricing pressure in the down housing market.

-18-

Operating expenses decreased $0.6 million to $97.8 million, or 18.8% of sales, in 2012, compared to $98.4 million, or 20.6% of sales, in 2011. Personnel costs increased slightly as benefits from general widespread wage reductions instituted in December 2011 were offset by higher variable incentive compensation from improved operating results as well as increased medical costs. Non personnel expenses were lower in 2012 as compared to 2011 as benefits from continued cost control efforts were recognized across various general expense categories. We recorded total stock-based compensation expense of $0.8 million in 2012 compared to $0.5 million in 2011.

Our results for the year ended December 31, 2012 included a gain on disposal of capital assets of $2.4 million, primarily from the sale of a previously closed facility. In addition, our results for 2012 and 2011 included goodwill impairment charges of $1.9 million and $0.4 million, respectively.

Net interest expense was $2.9 million in 2012 compared to $2.8 million in 2011 primarily due to higher average debt outstanding in 2012 versus 2011.

No income tax expense or benefit was recognized for the period ending December 31, 2012. Income tax benefit as a percentage of pre-tax loss for 2011 was approximately 2%. In 2011, a $0.3 million tax benefit in continued operations was recognized from a reduction in liabilities related to uncertain tax positions.

As a result of the foregoing factors, we incurred a loss from continuing operations of $0.1 million in 2012 as compared to a loss from continuing operations of $12.7 million in 2011.

Discontinued Operations

We recorded a loss of $0.4 million from discontinued operations in 2012 compared to loss of $0.5 million in 2011. The loss in both years is related to environmental and litigation expenses.

Fiscal 2011 Compared to Fiscal 2010

Continuing Operations

Net sales from continuing operations were $478.7 million in 2011, which were $11.0 million, or approximately 2%, higher than 2010. This increase is primarily due to the increase in our roofing business, which is partially storm driven, as well as a modest increase in housing starts.

Sales in the major product categories changed as follows in 2011 from 2010: millwork sales decreased 4% in 2011 to $215.1 million, building product sales increased 9% in 2011 to $210.3 million, and wood products increased 4% to $53.3 million in 2011 with a 5% increase in sales of engineered wood products and a 16% increase in sales of other wood products. The change in building product sales reflects the increase in our roofing business which is partially storm driven, as well as, a modest increase in housing starts. Fluctuations across product categories can occur based on, among other things, new product incentives, promotions, changes in product lines, commodity pricing and weather.

Gross margin increased approximately 4% to $88.6 million, or 18.5% of sales, in 2011 as compared to $85.2 million, or 18.2% of sales, in 2010. The higher margin percentage in 2011 reflects changes in the product mix, particularly in our millwork category, coupled with a concerted effort to increase margins. The higher margins were obtained even though building product sales, generally carrying lower margins, represented a higher percentage of total sales in 2011 as compared to 2010. In 2011 and 2010, gross margins continued to be negatively impacted by pricing pressure in the down housing market, which pressure may continue into 2012.

Operating expenses decreased $4.9 million to $98.4 million, or 20.6% of sales, in 2011, compared to $103.3 million, or 22.1% of sales, in 2010. Operating expenses for 2011 include $0.2 million of branch closure costs. Operating expenses for 2010 include $0.3 million of branch closure costs. The decrease in operating

-19-

expenses is primarily due to lower personnel costs and a lower cost structure, as a result of the continued cost reduction activities partially offset by higher fuel costs. We recorded total stock-based compensation expense of $0.6 million in 2011 compared to $0.8 million in 2010. The Company continues to review its cost structure for savings opportunities. As part of this process, in December 2011, we instituted widespread wage reductions.

Our results for the year ended December 31, 2011 included a $0.4 million goodwill impairment charge and our results for the year ended December 31, 2010 included a gain on disposal of capital assets of $0.4 million, primarily from the sale of a previously closed facility.

Net interest expense was $2.8 million in 2011 compared to $2.1 million in 2010 primarily due to higher average debt outstanding and higher borrowing rates in 2011 versus 2010.

Income tax benefit as a percentage of pre-tax loss for 2011 and 2010 was approximately 2% in both years. In 2011, a $0.3 million tax benefit in continued operations was recognized from a reduction in liabilities related to uncertain tax positions. In 2010, income from discontinued operations was used to offset loss from continued operations resulting in a $0.3 million tax benefit in continued operations.

As a result of the foregoing factors, we incurred a loss from continuing operations of $12.7 million in 2011 as compared to a loss from continuing operations of $19.4 million in 2010.

Discontinued Operations

We recorded a loss of $0.5 million from discontinued operations in 2011 compared to income of $0.5 million in 2010. The 2011 loss is related to environmental and litigation expenses. The 2010 income primarily resulted from the sale of a facility for a pretax gain of $0.9 million offset by $0.1 of environmental expense and $0.3 million in income tax expense related to discontinued operations.

Liquidity and Capital Resources

We depend on cash flow from operations and funds available under our revolving credit facility to finance seasonal working capital needs, capital expenditures and any acquisitions that we may undertake. Our working capital requirements are generally greatest in the second and third quarters, which reflect the seasonal nature of our business. The second and third quarters are also typically our strongest operating quarters, largely due to more favorable weather throughout many of our markets compared to the first and fourth quarters. We typically generate cash from working capital reductions in the fourth quarter of the year and build working capital during the first quarter in preparation for our second and third quarters. We also maintain significant inventories to meet rapid delivery requirements of our customers and to enable us to obtain favorable pricing, delivery and service terms with our suppliers. At December 31, 2012 and 2011, inventories and accounts receivables constituted approximately 71% and 67% of our total assets, respectively. We also closely monitor operating expenses and inventory levels during seasonally affected periods and, to the extent possible, manage variable operating costs to minimize seasonal effects on our profitability.

Operations—Cash from operating activities improved by $3.8 million to a usage of $4.3 million in 2012, compared to a $8.1 million usage of cash in 2011. In 2012, our net loss decreased $12.7 million compared to 2011. The net losses included goodwill impairment charges of $1.9 million in 2012 and $0.4 million in 2011. Accounts receivable increased by $2.3 million during 2012 and 2011. Days sales outstanding (“DSO”) decreased by 1.5 days to 30.3 days at December 31, 2012 from 31.8 days at December 31, 2011 based on annualized fourth quarter sales and quarter ended accounts receivable balances for the respective periods. Inventory increased by $10.2 million in 2012 compared to a decrease of $1.4 million in 2011. Our inventory turns decreased to 7.3 turns in 2012 from 7.4 turns in 2011. The increase in inventories as of December 31, 2012, is partially due to purchases made under advance buy opportunities and to support anticipated sales growth. Accounts payable increased by $2.9 million during 2012 compared to a $2.2 million increase in the year ago period. Days payable outstanding

-20-

decreased to 28.1 at December 31, 2012 from 28.3 at December 31, 2011 based on annualized fourth quarter costs of goods sold and quarter end accounts payable balances for the respective periods. Accounts payable did not increase to the same degree as inventories as a significant portion of the advance buy purchases were generally paid for at December 31, 2012.

Investing—Net cash provided by investing activities was $1.4 million in 2012, as compared to $2.0 million net cash used in investing activities in 2011. In 2012, the Company invested $1.9 million in machinery and equipment at various locations and received $3.3 million in proceeds from the sale of certain real estate from a previously closed facility. The Company invested $2.0 million in 2011 to acquire a distribution center in a market where our facility was previously leased as well as to acquire certain machinery and equipment at various locations.

Financing—Cash provided from financing activities of $4.5 million in 2012 reflects net debt borrowings of $6.3 million under our credit facility, less payments of $0.7 million for our capital lease and other debt obligations. Cash provided from financing of $10.0 million in 2011 reflects net debt borrowings of $10.3 million under our credit facility, less payments of $0.3 million for our capital lease and other debt obligations. In addition, in 2012 the Company repurchased 1.0 million shares of its common stock in a private transaction for $1.1 million.

Credit Facility—We have a $120.0 million asset based senior secured revolving credit facility (“credit facility”). In December 2012, we amended and extended our credit facility to among other things, incorporate certain real estate acquired in 2011, amend the cash dominion threshold, modify certain advance rates, and reduce the top tier interest rate. Borrowing availability under the credit facility is based on eligible accounts receivable, inventory and real estate. The real estate component of the borrowing base amortizes monthly over 12.5 years on a straight-line basis. Borrowings under the credit facility are collateralized by substantially all of our assets and are subject to certain operating limitations applicable to a loan of this type, which, among other things, place limitations on indebtedness, liens, investments, mergers and acquisitions, dispositions of assets, cash dividends and transactions with affiliates. The entire unpaid balance under the credit facility is due and payable on December 21, 2017, the maturity date of the credit agreement.

At December 31, 2012, under the credit facility, we had revolving credit borrowings of $59.1 million outstanding at a weighted average interest rate of 2.87%, letters of credit outstanding totaling $4.3 million, primarily for health and workers’ compensation insurance, and $24.3 million of additional committed borrowing capacity. We pay an unused commitment fee in the range of 0.30% to 0.375% per annum. In addition, we had $0.7 million of capital lease and other obligations outstanding at December 31, 2012.

The sole financial covenant in the credit facility is the fixed charge coverage ratio (“FCCR”) that must be tested by us if the excess borrowing availability falls below a range of $10.0 million to $15.0 million depending on our borrowing base and must also be tested on a pro forma basis prior to consummation of certain significant business transactions outside our ordinary course of business, as defined in the agreement. The FCCR is 1.25:1.00. At December 31, 2012, the FCCR testing threshold was $10.4 million as compared to $24.3 million of excess borrowing availability.

We believe that cash generated from our operations and funds available under the credit facility will provide sufficient funds to meet the operating needs of the business for at least the next twelve months. In 2012, the minimum FCCR was not required to be tested as excess borrowing availability was greater than the minimum threshold. However, if availability would have fallen below that threshold, we would not have met the minimum FCCR. If we are unable to maintain excess borrowing availability of more than the applicable amount in the range of $10.0 million to $15.0 million and were also unable to comply with this financial covenant, our lenders would have the right, but not the obligation, to terminate the loan commitments and accelerate the repayment of the entire amount outstanding under the credit facility. The lenders could also foreclose on our assets that secure the credit facility. In that event, we would be forced to seek alternative sources of financing, which may not be available on terms acceptable to us, or at all.

Off-Balance Sheet Arrangements

In addition to funds available from operating cash flows and our bank credit facility as described above, we use operating leases as a principal off balance sheet technique. Operating leases are employed as an alternative to purchasing certain property, plant and equipment. Future rental commitments, extending through the year 2020, under all non-cancelable operating leases in effect at December 31, 2012 total $29.0 million.

Cautionary Statement Relevant to Forward-looking Information for the Purpose of “Safe Harbor” Provisions of the Private Securities Litigation Reform Act of 1995

This Annual Report on Form 10-K and our annual report to shareholders contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including but not limited to statements regarding:

-22-

The words or phrases “will likely result,” “are expected to,” “will continue,” “is anticipated,” “believe,” “estimate,” “project” or similar expressions identify “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.

These statements present management’s expectations, beliefs, plans and objectives regarding our future business and financial performance. These forward-looking statements are based on current projections, estimates, assumptions and judgments, and involve known and unknown risks and uncertainties. We disclaim any obligation to publicly update or revise any of these forward-looking statements. There are a number of factors that could cause our actual results to differ materially from those expressed or implied in the forward-looking statements. These factors include, but are not limited to those set forth under Item 1A-Risk Factors.

ITEM 7A—QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have exposure to market risk as it relates to effects of changes in interest rates. We had debt outstanding at December 31, 2012 under our credit facility of $59.1 million.

All of our debt under our revolving credit facility accrues interest at a floating rate basis. If market interest rates for LIBOR had been different by an average of 1% for the year ended December 31, 2012, our interest expense and income before taxes would have changed by $0.6 million. These amounts are determined by considering the impact of the hypothetical interest rates on our borrowing cost. This analysis does not consider the effects of any change in the overall economic activity that could exist in such an environment. Further, in the event of a change of such magnitude, management may take actions to further mitigate its exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analysis assumes no changes in our financial structure.

We are subject to periodic fluctuations in the price of wood, steel commodities, petrochemical-based products and fuel. Profitability is influenced by these changes as prices change between the time we buy and sell the wood, steel or petrochemical-based products. Profitability is influenced by changes in prices of fuel. In addition, to the extent changes in interest rates affect the housing and remodeling market, we would be affected by such changes.

(In Millions, Except Share and Per Share Data)

1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PROCEDURES

Organization—Huttig Building Products, Inc. and subsidiary (the “Company” or “Huttig”) is a distributor of building materials used principally in new residential construction and in home improvement, remodeling and repair work. Huttig’s products are distributed through 27 distribution centers serving 41 states and are sold primarily to building materials dealers, national buying groups, home centers and industrial users including makers of manufactured homes.

Principles of Consolidation—The consolidated financial statements include the accounts of Huttig Building Products, Inc. and its wholly owned subsidiary. All significant inter-company accounts and transactions have been eliminated.

Reclassifications—Certain items in the 2011 financial statements have been reclassified to conform with the current year presentation.

Revenue Recognition—Revenues are recorded when title passes to the customer, which occurs upon delivery of product, less an allowance for returns, customer rebates and discounts for early payments. Returned products for which the Company assumes responsibility is estimated based on historical returns and are accrued as a reduction of sales at the time of the original sale.

Use of Estimates—The preparation of the Company’s consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Management makes estimates including but not limited to the following financial statement items; allowance for doubtful accounts, slow-moving and obsolete inventory, lower of cost or market provisions for inventory, long-lived asset and goodwill impairments, contingencies including environmental liabilities, accrued expenses and self-insurance accruals, and income tax expense and net deferred tax assets. Actual results may differ from these estimates.

Cash and Equivalents—The Company considers all highly liquid interest-earning investments with an original maturity of three months or less at the date of purchase to be cash equivalents. The carrying value of cash and equivalents approximates their fair value.

Accounts Receivable—Trade accounts receivable consist of amounts owed for orders shipped to customers and are stated net of an allowance for doubtful accounts. Huttig’s corporate management establishes an overall credit policy for sales to customers. The allowance for doubtful accounts is determined based on a number of factors including when customer accounts exceed 90 days past due and specific customer account reviews.

Inventory— Inventories are valued at the lower of cost or market. The Company’s entire inventory is comprised of finished goods. The Company reviews inventories on hand and records a provision for slow-moving and obsolete inventory. The provision for slow-moving and obsolete inventory is based on historical and expected sales. Approximately 86% of inventories were determined by using the LIFO (last-in, first-out) method of inventory valuation as of December 31, 2012 and December 31, 2011. The balance of all other inventories is determined by the average cost method, which approximates costs on a FIFO (first-in, first-out) method. The FIFO cost would be higher than the LIFO valuation by $10.5 million at December 31, 2012 and $9.6 million at December 31, 2011.

-30-

Supplier Rebates—The Company enters into agreements with certain vendors providing for inventory purchase based rebates upon purchasing volumes. The Company accrues the receipt of rebates base on purchases and records vendor rebates as a reduction of the cost of inventory purchased.

Property, Plant and Equipment—Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets and is charged to operating expenses. Buildings and improvements lives range from 3 to 25 years. Machinery and equipment lives range from 3 to 10 years. The Company recorded depreciation expense of $2.6 million, $2.7 million and $3.1 million in 2012, 2011 and 2010, respectively.

Goodwill—Goodwill for each reporting unit is reviewed for impairment annually or more frequently if certain indicators arise. The Company also reassesses useful lives of previously recognized intangible assets. The fair value the Company calculated includes multiple assumptions of its future operations to determine future discounted cash flows including but not limited to such factors as sales levels, gross margin rates, capital requirements and discount rates. The carrying value of goodwill is considered impaired when a reporting unit’s fair value is less than its carrying value. In that event, goodwill impairment is recognized to the extent recorded goodwill exceeds the implied fair value of that goodwill. As the Company continues to face a challenging housing environment and general uncertainty in the U.S. economy, its assumptions may change significantly in the future resulting in further goodwill impairments in future periods. See Note 2, “Goodwill and Other Intangible Assets” for additional information.

Valuation of Long-Lived Assets—The Company periodically evaluates the carrying value of its long-lived assets, including intangible and other tangible assets, when events and circumstances warrant such a review. The carrying value of long-lived assets is considered impaired when the anticipated undiscounted cash flows from such assets are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset. Fair market value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved.

Shipping and Handling—Costs associated with shipping and handling products to the Company’s customers are charged to operating expense. Shipping and handling costs were approximately $26.3 million, $26.6 million and $25.3 million in 2012, 2011 and 2010, respectively.

Income Taxes—Deferred income taxes reflect the impact of temporary differences between assets and liabilities recognized for financial reporting purposes and such amounts recognized are for tax purposes using currently enacted tax rates. A valuation allowance would be established to reduce deferred income tax assets if it is more likely than not that a deferred tax asset will not be realized. The Company includes interest and penalties related to uncertain tax positions in income tax expense. See Note 10, “Income Taxes” for additional information.

Net Loss Per Share—Basic net loss per share is computed by dividing loss available to common stockholders by weighted average shares outstanding. Diluted net loss per share reflects the effect of all other potentially dilutive common shares using the treasury stock method. See Note 11, “Basic and Diluted Net Loss Per Share” for additional information.

Accounting For Stock-Based Compensation—The Company has stock-based compensation plans covering the majority of its employee groups and a plan covering the Company’s Board of Directors. The Company accounts for share-based compensation utilizing the fair value recognition provisions of ASC 718, “Compensation-Stock Compensation”. The Company recognizes compensation cost for equity awards on a straight-line basis over the requisite service period for the entire award. See Note 9, “Stock and Incentive Compensation Plans” for additional information.

-31-

Concentration of Credit Risk—The Company is engaged in the distribution of building materials throughout the United States. The Company grants credit to customers, substantially all of whom are dependent upon the construction sector. The Company periodically evaluates its customers’ financial condition but does not generally require collateral. A significant portion of our sales are concentrated with a relatively small number of our customers. Our top ten customers represented 37% of our sales in 2012. In 2012, 2011, and 2010, the Company had a single customer representing 12%, 11% and 11% of total sales, respectively. This customer is a buying group for multiple building material dealers.

Segments—ASC 280, “Segment Reporting”, defines operating segments as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. At December 31, 2012 and 2011, under the definition of a segment, each of our branches is considered an operating segment of our business. Under ASC 280, operating segments may be aggregated if the operating segments have similar economic characteristics and if the nature of the products, distribution methods, customers and regulatory environments are similar. The Company has aggregated its branches into one reporting segment, consistent with ASC 280.

2.    GOODWILL AND OTHER INTANGIBLE ASSETS

Under ASC 350, “Intangibles-Goodwill and Other”, goodwill is reviewed for impairment annually or more frequently if certain indicators arise. In addition, the statement requires reassessment of the useful lives of previously recognized intangible assets.

The Company first assesses qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill test. The Company does not calculate the fair value of a reporting unit unless it determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount.

ASC 350 prescribes a two-step process for impairment testing of goodwill. During the fourth quarter of 2012 and 2011, the Company performed the annual test for impairment of its reporting units. The Company experienced lower than anticipated sales trends and operating income at one reporting unit. After performing the first step of the impairment test, we determined the carrying amounts of goodwill in our one reporting unit exceeded fair value. As a result, we performed the second step and determined that the goodwill was impaired by approximately $1.9 million. In 2011, the Company recorded goodwill impairment of $0.4 million related to the reduction in fair value of two reporting units. The following table summarizes goodwill activity for the three years ended December 31, 2012 (in millions):

-32-

The Company recorded amortization expense of $0.1 million, $0.1 million and $0.5 million for the years ended December 31, 2012, 2011 and 2010, respectively. The Company expects to record amortization expense for its existing intangible assets of approximately $0.1 million in each year 2013 through 2017, and in total, approximately $0.3 million thereafter.

3.    ALLOWANCE FOR DOUBTFUL ACCOUNTS

The allowance for doubtful accounts consisted of the following (in millions):

The Company recorded bad debt expense in 2012, 2011, and 2010 of 0.1% of net sales.

4.    LONG-TERM DEBT

Debt consisted of the following (in millions):

Credit Facility—The Company has a $120.0 million asset based senior secured revolving credit facility (“credit facility”). In December 2012, the Company amended and extended its credit facility to, among other things, incorporate certain real estate acquired in 2011, amend the cash dominion threshold, modify certain advance rates, and reduce the top tier interest rate. Borrowing availability under the credit facility is based on eligible accounts receivable, inventory and real estate. The real estate component of the borrowing base amortizes monthly over 12.5 years on a straight-line basis. Borrowings under the credit facility are collateralized by substantially all of the Company’s assets and are subject to certain operating limitations applicable to a loan of this type, which, among other things, place limitations on indebtedness, liens, investments, mergers and acquisitions, dispositions of assets, cash dividends and transactions with affiliates. The entire unpaid balance under the credit facility is due and payable on December 21, 2017, the maturity date of the credit agreement.

At December 31, 2012, under the credit facility, the Company had revolving credit borrowings of $59.1 million outstanding at a weighted average interest rate of 2.87%, letters of credit outstanding totaling $4.3 million, primarily for health and workers’ compensation insurance, and $24.3 million of additional committed borrowing capacity. The Company pays an unused commitment fee in the range of 0.30% to 0.375% per annum. In addition, the Company had $0.7 million of capital lease and other obligations outstanding at December 31, 2012.

The sole financial covenant in the credit facility is the fixed charge coverage ratio (“FCCR”) that must be tested by the Company if the excess borrowing availability falls below a range of $10.0 million to $15.0 million depending on the Company’s borrowing base and must also be tested on a pro forma basis prior to consummation

-33-

of certain significant business transactions outside the Company’s ordinary course of business, as defined in the agreement. The FCCR is 1.25:1.00. At December 31, 2012, the FCCR testing threshold was $10.4 million and the Company had $24.3 million of excess borrowing availability.

The Company believes that cash generated from its operations, funds available under the credit facility will provide sufficient funds to meet the operating needs of the business for at least the next twelve months. In 2012 and 2011, the minimum FCCR was not required to be tested as excess borrowing availability was greater than the minimum threshold. However, if availability would have fallen below that threshold, the Company would not have met the minimum FCCR. If the Company was unable to maintain excess borrowing availability of more than the applicable amount in the range of $10.0 million to $15.0 million and was also unable to comply with this financial covenant, its lenders would have the right, but not the obligation, to terminate the loan commitments and accelerate the repayment of the entire amount outstanding under the credit facility. The lenders could also foreclose on the Company’s assets that secure the credit facility. In that event, the Company would be forced to seek alternative sources of financing, which may not be available on terms acceptable to it, or at all.

Maturities—At December 31, 2012, the aggregate scheduled maturities of debt are as follows (in millions):

The fair value of long-term debt, as calculated using the aggregate cash flows from principal and interest payments over the life of the debt, was approximately $59.1 million and $51.6 million at December 31, 2012 and 2011, respectively, based upon a discounted cash flow analysis using current market interest rates. The fair value measurement inputs for long-term debt are classified as Level 3 (unobservable inputs) in the valuation hierarchy as defined by ASC 820, “Fair Value Measurements and Disclosures”.
