PART I

Item 1.    Business

The Company

        Griffon Corporation (the "Company" or "Griffon"), is a diversified management and holding company that conducts business through wholly-owned subsidiaries. Griffon oversees the operations of its subsidiaries, allocates resources among them and manages their capital structures. Griffon provides direction and assistance to its subsidiaries in connection with acquisition and growth opportunities as well as in connection with divestitures. Griffon also seeks out, evaluates and, when appropriate, will acquire additional businesses that offer potentially attractive returns on capital to further diversify itself.

        Headquartered in New York, N.Y., the Company was incorporated in New York in 1959, and was reincorporated in Delaware in 1970.

        Griffon currently conducts its operations through three segments:

•

Telephonics Corporation ("Telephonics") designs, develops and manufactures high-technology integrated information, communication and sensor system solutions for use in military and commercial markets worldwide. Telephonics' revenue was 34% of Griffon's consolidated revenue in 2010, 32% in 2009 and 29% in 2008.



•

Home & Building Products consists of two companies:



•

Clopay Building Products Company ("CBP") is a leading manufacturer and marketer of residential, commercial and industrial garage doors to professional installing dealers and major home center retail chains. CBP's revenue was 30% of Griffon's consolidated revenue in 2010, 33% in 2009 and 34% in 2008.



•

Ames True Temper, Inc. ("ATT"), acquired by Griffon on September 30, 2010, is a global provider of non-powered landscaping products that make work easier for homeowners and professionals. Due to the acquisition of ATT occurring on September 30, 2010, none of ATT's 2010 results of operations were included in Griffon's year end results. ATT's 2010 pro forma revenue was $444 million, or 26% of Griffon's pro forma 2010 revenue of $1.7 billion (unaudited), giving affect to the acquisition of ATT as if it had occurred on October 1, 2009.



•

Clopay Plastic Products Company ("Plastics") is an international leader in the development and production of embossed, laminated and printed specialty plastic films used in a variety of hygienic, health-care and industrial applications. Plastics' revenue was 36% of Griffon's consolidated revenue in 2010, 35% in 2009 and 37% in 2008.

(Unless otherwise indicated, any reference to years or year-end refers to the fiscal year ending September 30)

        On September 30, 2010, Griffon purchased all of the outstanding stock of CHATT Holdings, Inc. ("ATT Holdings"), the parent of ATT, on a cash and debt-free basis, for $542 million in cash, subject to certain adjustments. ATT is a global provider of non-powered lawn and garden tools, wheelbarrows, and other outdoor work products to the retail and professional markets. ATT's brands include Ames®, True Temper®, Ames True Temper®, Garant®, Union Tools®, Razor-back®, Jackson®, Hound Dog® and Dynamic Design^TM. ATT's brands hold the number one or number two market positions in their respective major product categories.

        In connection with the ATT acquisition, Clopay Ames True Temper Holding Corp. ("Clopay Ames"), a wholly-owned subsidiary of Griffon, entered into a $375 million secured term loan facility ("Term Loan") and a new $125 million asset based lending facility ("New ABL"). The acquisition, including all related transaction costs, was funded by proceeds of the Term Loan, $25 million drawn under the New ABL, and $168 million of Griffon cash. ATT's previous outstanding debt has been

2

repaid in connection with the acquisition. Following the ATT transaction, Griffon holds consolidated cash balances of $170 million at September 30, 2010.

        The purchase of ATT occurred on September 30, 2010. Accordingly, ATT's operating results are not included in Griffon's consolidated statements of operations or cash flows, or footnotes relating thereto for any year presented, except where explicitly stated as pro-forma results. All pro forma results are unaudited and, unless otherwise stated, give effect to the acquisition of ATT as if it had occurred on October 1, 2009. The Griffon consolidated balance sheet at September 30, 2010 and related notes thereto include ATT's balances at that date.

        In July 2010, Griffon retired substantially all of the outstanding 4% Convertible Subordinated Notes due 2023 when they were put to Griffon at par.

        In December 2009, Griffon issued $100 million principal amount of 4% Convertible Subordinated Notes due 2017 (the "2017 Notes") at an initial conversion ratio of 67.0799 shares of Griffon common stock per $1,000 principal amount of the 2017 Notes, corresponding to an initial conversion price of approximately $14.91 per share.

        In 2008, Griffon substantially strengthened its balance sheet by refinancing its senior debt and raising $248.6 million in gross proceeds through a common stock rights offering, along with an investment by GS Direct, L.L.C. ("GS Direct"), an affiliate of Goldman Sachs.

        As a result of the downturn in the residential housing market, in 2008, Griffon exited substantially all of the operating activities of its Installation Services segment; this segment sold, installed and serviced garage doors, garage door openers, fireplaces, floor coverings, cabinetry and a range of related building products primarily for the new residential housing market. Operating results of substantially all the Installation Services segment have been reported as discontinued operations in the consolidated statements of operations for all periods presented herein, and the Installation Services segment is excluded from segment reporting (see the Discontinued Operations footnote in the Notes to Consolidated Financial Statements).

        Griffon makes available, free of charge through its website at www.griffoncorp.com, its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) of the Securities Exchange Act of 1934, as soon as reasonably practicable after such material is filed with or furnished to the Securities and Exchange Commission (the "SEC").

        For information regarding revenue, profit and total assets of each segment, see the Business Segments footnote in the Notes to Consolidated Financial Statements.

Reportable Segments:

Telephonics Corporation

        Telephonics specializes in advanced electronic information and communication systems for defense, aerospace, civil, industrial, and commercial applications for the United States and international markets. Telephonics designs, develops, manufactures, sells, and provides logistical support for aircraft intercommunication systems, radar, air traffic management, identification friend or foe equipment, Integrated Homeland Security Systems and custom, mixed-signal, application-specific, integrated circuits. Telephonics is a leading supplier of airborne maritime surveillance radar and aircraft intercommunication management systems, the segment's two largest product lines. In addition to its traditional defense products used predominantly by the United States ("U.S") Government and its agencies, Telephonics has adapted its core technologies to products used in international markets in an effort to further increase its presence in both non-defense government and commercial markets. In 2010, approximately 73% of the segment's sales were to the United States Government and agencies thereof, as a prime or subcontractor, 19% to international customers and 8% to U.S. commercial customers.

3

        Telephonics employs approximately 1,400 employees.

        Griffon believes that Telephonics' advanced systems and sub-systems are well-positioned to address the needs of an electronic battlefield with emphasis on providing situational awareness to the warfighters through the retrieval and dissemination of timely data for use by highly mobile ground, air and sea-going forces. Telephonics anticipates that the need for such systems will increase in connection with the increasingly active role that the military is playing in the war on terrorism, both at home and abroad. In recent years, Telephonics has increasingly focused its technologies and core competencies in the growing Homeland Security, Air Traffic Management, and Unmanned Aerial Vehicle (UAV) markets.

Programs and Products

        Telephonics is generally a first-tier supplier to prime contractors in the defense industry such as Lockheed Martin, Boeing, Northrop Grumman, General Dynamics, BAE Systems, MacDonald Dettwiler, Sikorsky Aircraft, and is often a prime contractor to the U.S. Department of Defense and the U.S. Department of Homeland Security ("Homeland Security"). The significant contraction and consolidation in the U.S. and international defense industry provides opportunities for established first-tier suppliers to capitalize on existing relationships with major prime contractors and play a larger role in defense systems development and procurement, for the foreseeable future.

        As a result of its performance on a prior manufacturing contract with Syracuse Research Corporation, Telephonics received a subcontract award from Sierra Nevada Corporation for both production and support of counter-IED devices which resulted in $46 million of revenue in 2010 and $11 million of revenue in 2009.

        Telephonics continues to direct resources towards Homeland Security programs, and was previously selected by Boeing Company to participate in the Secure Border Initiative net (SBInet) program. Additionally, Telephonics has completed a contract from the U.S. Customs and Border Protection for mobile surveillance systems as part of Homeland Security's initiative to protect the U.S. borders, and continues to pursue other opportunities with this customer. These programs represent strategic advances for Telephonics by allowing it to expand its core technical expertise into this nascent and growing Homeland Security market.

        In 2010, Telephonics was selected by Northrop Grumman as the radar supplier for the U.S. Navy's Firescout MQ-8 program, which is a vertical take-off and landing UAV platform. This strategic win positions Telephonics, with both its radar and communications products, as a strong competitor in this growing market segment.

Backlog

        The funded backlog for Telephonics was approximately $407 million at September 30, 2010, compared to $393 million at September 30, 2009. The increase in backlog is primarily attributable to additional funding received for the MH-60R program, a unique, fully integrated multi-mode radar and identification friend or foe interrogator system. Approximately 73% of the current backlog is expected to be filled during 2011.

Sales and Marketing

        Telephonics has technical business development personnel who act as the focal point for its marketing activities and sales representatives who introduce its products and systems to customers worldwide.

        The U.S. Government through its agencies, Lockheed Martin Corporation and the Boeing Company are significant customers of Telephonics. The loss of these customers would have a material adverse effect on Telephonics' business. Notwithstanding the significance of Lockheed Martin Corporation and Boeing Company, Telephonics sells to a diverse group of other domestic and

4

international defense industry contractors, as well as others who use Telephonics products for commercial use.

        Telephonics participates in a range of long-term defense and non-military government programs, both in the U.S. and internationally. Telephonics has developed a base of installed products that generate significant recurring revenue from product enhancements and retrofits as well as providing spare parts and customer support. Due to the inherent complexity of these electronic systems, Telephonics believes that its incumbent status on major platforms provides a competitive advantage in the selection process for platform upgrades and enhancements. Furthermore, Telephonics believes that its ability to leverage and apply its advanced technology to new platforms provides a competitive advantage when bidding for new business.

        In recent years, the segment has significantly expanded its customer base in international markets. Telephonics' international projects include contracts with MacDonald Dettwiler as part of Canada's CP-140 Aurora Aircraft Modernization program, with General Dynamics for the Canadian Maritime Helicopter Program, and a number of contracts with the Civil Aviation Authority of China for air traffic management systems for Mainland China.

Manufacturing Facilities

        Telephonics' facilities are principally located in the United States, primarily in New York, with one facility in Sweden. In 2010, Telephonics added an additional New York facility to provide increased manufacturing capacity, as well as a state-of-the-art Air Traffic Management high-tech development laboratory and demonstration center. Telephonics also established its Technical Support Services Center in Elizabeth City, North Carolina which supports aircraft integration and upgrade activities, in addition to providing support services to customers.

Research and Development

        In an effort to ensure customer satisfaction and loyalty, Telephonics seeks to anticipate the needs of core markets by investing in research and development ("R&D") to provide solutions well in advance of its competitors. Telephonics continually updates its core technologies through internally funded R&D while coordinating with its customers at the earliest stages of new program development. The selection of R&D projects is based on available opportunities in the marketplace, as well as input from Telephonics' customers. Telephonics is a technological leader in its core markets and intends to pursue new growth opportunities by leveraging its systems design and engineering capabilities and incumbent position on key platforms.

        In addition to products for defense programs, Telephonics technology is also used in commercial applications such as airborne weather, search and rescue radar, and air traffic management systems. Telephonics' reputation for innovative product design and engineering capabilities, especially in the areas of voice and data communications, radio frequency design, digital signal processing, networking systems, inverse synthetic aperture radar and analog, digital and mixed-signal integrated circuits, will continue to enhance its ability to secure, retain and expand its participation in defense programs and commercial opportunities.

        Telephonics often designs its products to exceed customers' minimum specifications, providing its customers with greater performance, flexibility, and value. Telephonics believes that early participation and communication with its customers in the requirements definition stages of new program development, increases the likelihood that its products will be selected and integrated as part of a total system solution.

Competition

        Telephonics competes with major manufacturers of electronic information and communication systems, as well as several smaller manufacturers of similar products. Telephonics endeavors to design

5

products with greater performance and flexibility than its competitors while competing on the basis of technology, design, quality and price.

Home & Building Products:

        Home & Building Products includes CBP and ATT. These businesses both serve The Home Depot, Inc. ("Home Depot"), a significant customer, as well as purchase common raw materials. These businesses are exploring opportunities to leverage their manufacturing, sourcing and distribution footprints.

Clopay Building Products

        CBP is the largest manufacturer and marketer of residential garage doors and among the largest manufacturers of commercial sectional doors in the United States. The majority of CBP's sales are for home remodeling and renovation, with the balance for the new residential housing and commercial building markets. Sales into the home remodeling market are being driven by the continued aging of the housing stock, existing home sales activity, the trend of improving home appearance, as well as improved energy efficiency, leading to increased demand for insulated doors. CBP employs approximately 1,350 employees.

        The garage door industry has been negatively impacted by the recessionary effect on the residential housing market. Key statistics regarding housing sales, construction permits and starts in 2010 and 2009 were substantially lower than the prior decade. According to the National Association of Home Builders, current data compared to the prior year shows new home starts up 4% with new home sales down 21% and the inventory of new homes stands at an eight month supply. Current year existing home sales are down 19% versus the prior year and the inventory of existing homes now stands at a 10.7-month supply. According to industry sources, the residential and commercial sectional garage door market for 2009 was estimated to be $1.5 billion, declining approximately $200 million from the prior year.

Brands

        CBP brings nearly 50 years of experience and innovation to the garage door industry. Our strong family of brands includes Clopay®, America's Favorite Garage Doors®; Holmes Garage Door Company® and IDEAL Door®. Clopay is the only residential garage door brand to hold the Good Housekeeping Seal of Approval. With two manufacturing facilities and 51 distribution centers across the U.S. and Canada, CBP is North America's leading manufacturer of residential garage doors, a preferred supplier of commercial overhead doors and in 2010 launched a complete line of entry door systems uniquely designed to complement its popular residential garage door styles.

Products and Service

        CBP manufactures a broad line of residential sectional garage doors with a variety of options, at varying prices. CBP offers garage doors made primarily from steel, plastic composite and wood, and also sells related products, such as garage door openers, manufactured by third parties.

        CBP also markets commercial sectional doors, which are similar to residential garage doors, but are designed to meet the more demanding performance specifications of a commercial application.

Sales and Marketing

        CBP distributes its products through a wide range of distribution channels, including installing dealers, retailers and wholesalers. CBP owns and operates a national network of 51 distribution centers. Additionally, products are sold to approximately 2,000 independent professional installing dealers and to major home center retail chains. CBP maintains strong relationships with its installing dealers and

6

believes it is the largest supplier of residential garage doors to the retail and professional installing channels in the North America.

        CBP is the principal supplier of residential garage doors throughout North America to Home Depot and Menards. The loss of either of these customers would have a material adverse effect on CBP's and Griffon's business. CBP distributes its garage doors directly to customers from its manufacturing facilities and through its distribution centers located throughout the United States and Canada. These distribution centers allow CBP to maintain an inventory of garage doors near installing dealers and provide quick-ship service to retail and professional dealer customers.

Manufacturing and Raw Materials

        As part of its cost structure review, in June 2009, Griffon announced plans to consolidate facilities in its CBP segment. These actions are scheduled to be completed in early calendar 2011, consistent with the plan. CBP estimates it will incur pre-tax exit and restructuring costs approximating $11 million, substantially all of which will be cash charges; charges include $2 million for one-time termination benefits and other personnel costs, $1 million for excess facilities and related costs, and $8 million for other exit costs, primarily in connection with production realignment. CBP expects approximately $11 million in capital expenditures in order to effectuate the restructuring plan. CBP spent $4.2 million and $7.3 million in 2010 for the restructuring plan and related capital expenditures, respectively, and since inception through September 30, 2010, has spent $5.4 million and $9.3 million of restructuring and related capital expenditures to-date for the plan, respectively.

        The facility consolidation is part of CBP's continuing efforts to improve and streamline its manufacturing processes. CBP's engineering and technological expertise, combined with its capital investment programs, generally has enabled it to efficiently manufacture products in large volume and meet changing customer needs in a timely manner. CBP uses proprietary manufacturing processes to produce the majority of its products. Certain machinery and equipment are internally modified to achieve manufacturing objectives. These manufacturing facilities produce a broad line of high quality garage doors for distribution to professional installer, retail and wholesale channels.

        The principal raw material used in CBP's manufacturing is galvanized steel. CBP also utilizes certain hardware components, as well as wood and insulated foam. All of these raw materials are generally available from a number of sources.

Research and Development

        CBP operates a technical development center where its research engineers work to design, develop and implement new products and technologies and perform durability and performance testing of new and existing products, materials and finishes. Also at this facility, the process engineering team works to develop new manufacturing processes and production techniques aimed at improving manufacturing efficiencies.

Competition and market conditions

        The garage door industry is characterized by several large national manufacturers and many smaller regional and local manufacturers. CBP competes on the basis of service, quality, price, brand awareness and product design.

        CBP's brand names are widely recognized in the building products industry. CBP believes that it has earned a reputation among installing dealers, retailers and wholesalers for producing a broad range of innovative, high-quality doors. CBP's market position and brand recognition are key marketing tools for expanding its customer base, leveraging its distribution network and increasing its market share.

Ames True Temper

        ATT is the leading U.S. and a global provider of non-powered landscaping products that make work easier for homeowners and professionals. ATT has a global manufacturing strategy, based primarily upon a blend of domestic manufacturing and sourced product, which makes ATT cost competitive while allowing it to provide a high level of customer service. ATT employs approximately 1,600 employees.

Brands

        ATT brands are among the most recognized across primary product categories in the North American non-powered landscaping products market. ATT's brand portfolio includes Ames®, True Temper®, Ames True Temper®, Garant®, Hound Dog®, Westmix and Dynamic Design™, as well as contractor-oriented brands including UnionTools®, Razor-Back® Professional Tools and Jackson® Professional Tools. This strong portfolio of brands allows ATT to build and maintain long-standing relationships with the leading companies that sell ATT product categories and to offer specific branding strategies for key retail customers. In addition to the brands listed, ATT also sells unbranded products to capture the opening price point at major retailers or to satisfy the entire product offering of a customer. While the opening price point category historically has not generated significant revenue, it is an important part of establishing a step-up strategy. As an example, opening price point products are used for long handle tools to strengthen the position of that category's "good," "better" and "best" product lines. ATT also manufactures and distributes products under proprietary customer brands, as requested.

Products

        ATT manufactures and markets one of the broadest product portfolios in the non-powered landscaping product industry. This portfolio is anchored by two core product categories: long handle tools and wheelbarrows. As a result of ATT's brands' strengths, high product quality, high level of customer service and strong customer relationships, ATT has earned market-leading positions in the long handle tool and wheelbarrow product lines. The following is a brief description of ATT's primary product lines:

•

Long Handle Tools:  A broad line of internally designed and developed long handle tools including shovels, spades, scoops, rakes, hoes, cultivators, weeders, post hole diggers, scrapers, edgers and forks are marketed under leading brand names including Ames®, True Temper®, Jackson® Professional Tools, UnionTools®, Razor-Back® Professional Tools, Greenlife® and Garant®. Numerous types of heads, including poly, steel and aluminum, and various handles manufactured from wood, steel, aluminum, engineered polymers and fiberglass, are offered. The long handle tool line is designed to include a wide range of handle lengths, blade sizes and various features to meet the needs of end-users. Long handle tools are both a manufactured and sourced product.



•

Wheelbarrows:  ATT designs, develops and manufactures a full line of wheelbarrows and lawn carts, primarily under the Ames®, True Temper®, Jackson® Professional Tools, Razor-Back® Professional Tools, UnionTools® and Garant® brand names. The wheelbarrows range in size (2 cubic feet to 10 cubic feet), material (poly and steel), tray form, tire type, handle length and color based on the needs of homeowners, landscapers and contractors.



•

Planters and Lawn Accessories:  ATT is a distributor of indoor and outdoor planters and accessories, sold under the Dynamic Design™ brand name, as well as various private label brands. ATT, along with outside resources, design the products which are manufactured by third party suppliers. A wide range of designs and planter sizes (from 6 to 24 inches), available in various colors and primarily made of resin and fiberglass, are offered. In 2009, the Ecogardener™ line of planters which are made of approximately 90% renewable resources that are biodegradable, was introduced.

8

•

Snow Tools:  A complete line of snow tools is marketed under the Ames True Temper®, True Temper® and Garant® brand names. The snow tool line includes shovels, pushers, roof rakes, sled sleighs, scoops and ice scrapers for which ATT internally designs, develops and manufactures. A wide range of handles and shapes made of wood, aluminum and steel are included in the line as well as a wide range of head sizes and shapes made of poly, steel and aluminum.



•

Striking Tools:  Axes, picks, mattocks, mauls, wood splitters, sledgehammers and repair handles make up the striking tools product line. These products are marketed under the True Temper®, Jackson® Professional Tools, UnionTools®, Garant® and Razor-Back® Professional Tools brand names. ATT internally designs these products which come in various sizes, forms and weighted heads that are made of steel with wood, fiberglass or composite handles. Striking tools are both a manufactured and sourced product.



•

Pruning:  The pruning line is made up of pruners, loppers, shears and other tools sold primarily under the Ames® and True Temper® brand names. Along with outside resources, ATT designs the products which are manufactured by third party suppliers. The pruning tools are made of aluminum and steel blades with handles made from a variety of materials depending upon the tool. A variety of handle sizes, lengths, cutting blade styles and sizes and cutting capacities exist in the product line.



•

Garden Hoses and Hose Reels:  ATT offers a wide range of both manufactured and sourced garden hoses and hose reels under the Ames® and Jackson® Professional Tools brand names. The hoses are made of rubber and vinyl and come in a variety of lengths (6 to 100 feet), uses (both home and industrial applications) and styles (such as non-kinking and abrasion resistant material). The hose reels are made of resin, metal and aluminum and have a hose capacity up to 300 feet. Both the garden hoses and hose reels are designed in house and through outside resources.

Customers

        ATT sells products primarily in the U.S. and Canada through (1) retail centers, including home centers and mass merchandisers, such as Home Depot, Lowe's Companies, Wal-Mart, Canadian Tire, and Rona (2) wholesale chains, including hardware stores and garden centers, such as Ace, Do-It-Best and True Value and (3) industrial distributors, such as Grainger and McMaster-Carr.

        Home Depot and Lowes are significant customers of ATT. The loss of either of these customers would have a material effect on ATT's and Griffon's business.

Product Development and Intellectual Property

        ATT product development efforts focus on both new products and product line extensions. Products are developed through in-house industrial design and engineering staffs and through relationships with a number of outside product engineering and design firms to introduce new products timely and cost effectively. Examples of recent new product initiatives include the Water Genie® Bottomless Watering Can™ with integrated hose reel in a lightweight easy-to-use product, Pulverizer® multi-demolition tool, SnoBoss® sleigh shovel for ergonomic shoveling, EcoGardener™ series of long handle tools made with bamboo handles and recycled steel heads, and three new lines of planters made with new materials: EcoGardener™ series of planters which are biodegradable when buried, Ceramix® planters which look like ceramic but are lighter weight and more durable, and Roto Molded planters which use double wall construction for added strength.

        ATT holds various registered U.S. trademarks and issued U.S. patents and its wholly-owned subsidiaries hold trademarks, patents and copyrights in countries where products are sold. ATT also holds an exclusive license in the U.S. and Canada to manufacture Clog-Free™ rakes.

9

Sales and Marketing

        ATT's sales organization is structured by distribution channel in the U.S., and by country internationally. In the U.S., a dedicated team of sales professionals is provided for each of the large retail customers. Offices are maintained adjacent to each of the three largest customers' headquarters, as well as dedicated in-house sales analysts at the corporate office. In addition, sales professionals are assigned to domestic, wholesale and industrial distribution channels. Sales teams located in Canada, Australia and Ireland are available to handle the Canadian, Australian and European sales efforts, respectively. In 2008, ATT initiated marketing and distribution efforts in Mexico. To assist clients in marketing products and responding to new customer trends, ATT has created teams headed by a product line marketing director focused on each product line. Each team is responsible for implementing category-specific marketing strategies, including new product development, Stock Keeping Unit rationalization and support for key accounts. ATT offers internal graphics capabilities to design catalogs, labels, point of purchase and other sales materials. In addition, point of sale and sell-through activity is monitored to identify product opportunities and develop merchandising programs to help customers achieve their sales objectives. ATT also works closely with external research firms, design studios and product engineering organizations to identify and capitalize on emerging consumer and professional end user trends.

Raw Materials and Suppliers

        ATT's primary raw material inputs include resin (primarily polypropylene and high density polyethylene), wood (mainly ash, hickory and poplar logs) and steel (hot rolled and cold rolled). In addition, some key materials and components are purchased, such as metal fork components, wheelbarrow tires, shovel heads and fiberglass handles; however, most of the final assembly is completed internally in order to ensure consistent quality for customers. All raw materials used by ATT are generally available from a number of sources

Competition

        The non-powered landscaping product industry is highly competitive and fragmented. Most competitors consist of small, privately-held companies focusing on a single product category. Some competitors such as Fiskars and Truper compete in various tool categories, Suncast in hose reels and accessories and Colorite/Swan in garden hoses. In addition, there is competition from imported or sourced products from China, India and other low-cost producing countries, particularly in long handled tools, wheelbarrows, planters, striking tools and pruning tools.

        The principal factors by which ATT competes are quality, performance, price, brand strength, reliability and customer service, with the relative importance of each factor varying by product line. Additionally, ATT is a party to three Asian joint ventures that enable ATT to compete with products from low-cost producing countries. The overall size, product depth and category knowledge provide ATT with a competitive advantage. In addition, some offshore manufacturers lack sufficient distribution capabilities to service large retailers. Extensive wood mill infrastructure and expertise in curing wood handles, coupled with the proximity to American ash and hickory sources, provide ATT with a competitive advantage over offshore manufacturers.

Distribution

        ATT has nine operational distribution centers. In the U.S., the largest of these are a 1.2 million square foot facility in Carlisle, Pennsylvania and a 400,000 square foot facility in Reno, Nevada. Finished goods from manufacturing sites are transported to these facilities by internal fleet, over the road trucking and rail. Additionally, light assembly is performed at the Carlisle, Pennsylvania and Reno, Nevada locations. Distribution centers are maintained in Canada and Ireland and ATT utilizes a third party distribution center in Mexico City, Mexico. Australia has five distribution centers. Streamlined

10

logistics and manufacturing capabilities allow ATT to deliver products cost effectively with shorter lead times, providing customers significant value for products and services.

Joint Ventures

        ATT holds joint venture interests ranging from 25% to 35% in three separate joint ventures. ATT sources products from these joint ventures which enables them to compete with products from low cost countries. ATT does not share in the profits or losses of the joint ventures. Under the terms of the joint venture agreements, ATT is entitled to minority representation on the board of directors of each joint venture, and does not receive financial information.

Clopay Plastic Products

        Plastics produces and develops specialty plastic films and laminates for a variety of hygienic, health care and industrial uses in the United States and certain international markets. Products include thin gauge embossed and printed films, elastomeric films and laminates of film and non-woven fabrics. These products are used primarily as moisture barriers in disposable infant diapers, adult incontinence products and feminine hygiene products, as protective barriers in single-use surgical and industrial gowns, drapes and equipment covers, as packaging for hygienic products, house wrap and other products. Plastics' products are sold through a direct sales force primarily to multinational consumer and medical products companies.

        Plastics employs approximately 1,350 employees.

        The markets in which Plastics participates have been affected by several key trends over the past five years. These trends include the increased use of disposable products in developing countries and favorable demographics, including increasing immigration in major global economies. Other trends representing significant opportunities for manufacturers include the continued demand for innovative products such as cloth-like, breathable, laminated and printed products, and large consumer products companies' need for global supply partners. Notwithstanding the positive trends affecting the industry, product design changes by the customer can change the products manufactured by Plastics and the associated demand.

        Plastics believes that its business development activities targeting major multinational and regional producers of hygiene, healthcare and related products and its investments in its technology development capability and capacity increases will lead to additional sales of new and related products.

11

Products

        Plastics' specialty plastic film is a thin-gauge film engineered to provide certain performance characteristics and manufactured from polymer resins. A laminate is the combination of a plastic film and a woven or non-woven fabric. These products are produced using both cast and blown extrusion and laminating processes. High speed, multi-color custom printing of films and customized embossing patterns further differentiate the products. Specialty plastic film products typically provide a unique combination of performance characteristics, such as breathability, barrier properties, elastic properties, processability and aesthetic appeal, that meet specific, proprietary customer needs.

Sales and Marketing

        Plastics sells its products primarily in North America, Europe, and South and Central America with additional sales in Asia Pacific. Plastics utilizes an internal direct sales force, with Plastics' senior management actively participating in developing and maintaining close contacts with customers.

        Plastics' largest customer is Procter & Gamble, Co. ("P&G"), which has accounted for approximately 50% of its revenue over the last five years. The loss of this customer would have a material adverse effect on the business. Notwithstanding the significance of P&G, Plastics sells to a diverse group of other leading consumer, health care and industrial companies.

        Plastics seeks to expand its market presence by providing innovative products and services to major international consumer products companies. Specifically, Plastics believes that it can continue to increase its North American sales and expand internationally through ongoing product development and enhancement, and by marketing its technologically-advanced films, laminates and printed films for use in all of its markets. Operations in Germany, Brazil and most recently China, provide a strong platform for additional sales growth in international markets.

Research and Development

        Plastics is an industry leader in the research, design and development of specialty plastic film and laminate products. Plastics operates a technical center where polymer chemists, scientists and engineers work independently and in partnerships with customers to develop new technologies, products, processes and product applications.

        Plastics' research and development efforts have resulted in many inventions covering embossing patterns, improved processing methods, product formulations, product applications and other proprietary technology. Products developed include microporous breathable films and cost-effective printed films and laminates. Microporous breathability provides for moisture vapor transmission and airflow while maintaining barrier properties resulting in improved comfort and skin care. Elastic laminates provide the user with improved comfort and fit. Printed films and laminates provide consumers preferred aesthetics, such as softness and visual appeal. Plastics holds a number of patents for its specialty film and laminate products and related manufacturing processes. While patents play a significant role, Plastics believes that its proprietary know-how and the knowledge, ability and experience of its employees are more significant to it long-term success.

International Operations

        Plastics has two operations in Germany from which it sells plastic films throughout Europe and the Middle East. Plastics also has operations in Brazil which manufacture plastic hygienic and specialty films. Plastics' international operations provide a platform to broaden participation in Europe, the Middle East, South America and Asia and strengthen Plastics' position as a global supplier.

Manufacturing and Raw Materials

        Specialty plastic film and laminate products are manufactured using high-speed equipment designed to meet stringent tolerances. The manufacturing process consists of melting a mixture of

12

polymer resins and additives, and forcing this mixture through a die and rollers to produce embossed films. Laminates of films and non-wovens are manufactured by a variety of techniques to meet customer needs. In addition, films and laminates can be printed.

        Plastic resins, such as polyethylene and polypropylene, and non-woven fabrics are the basic raw materials used in the manufacture of substantially all Plastics' products. The price of resin has fluctuated dramatically over the past five years primarily due to volatility in oil prices and producer capacity. Resins are purchased in pellet form from several suppliers. Sources for raw materials are believed to be adequate for current and anticipated needs.

Competition

        Plastics has a number of competitors, some of which are larger, in the specialty plastic films and laminates market. Plastics competes on quality, service and price using its technical expertise, product development capabilities and broad international footprint to enhance its market position, build and maintain long-term customer relationships and meet changing customer needs.

Employees

        Griffon and its subsidiaries employ approximately 5,700 people located throughout the U.S., Canada, Europe, Brazil, China, Mexico and Australia. Approximately 515 of these employees are covered by collective bargaining agreements in the U.S., primarily with an affiliate of the American Federation of Labor and Congress of Industrial Organizations ("AFL-CIO"), United Brotherhood of Carpenters and Joiners of America ("UBCJA"), International Brotherhood of Teamsters ("IBT") and the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy Allied Industrial and Service Workers International Union. Additionally, approximately 200 employees in Canada are represented by the Trade Union Advisory Committee. Griffon believes its relationships with its employees are satisfactory.

13

Executive Officers of the Registrant

        The following is a current list of Griffon's executive officers:

Regulation

        Griffon's operations are subject to various environmental, health, and employee safety laws and regulations. Griffon believes that it is in material compliance with these laws and regulations. Historically, compliance with environmental laws has not materially affected, and is not expected to materially affect, Griffon's capital expenditures, earnings or competitive position in the future.

14

Nevertheless, Griffon cannot guarantee that, in the future, it will not incur additional costs for compliance or that such costs will not be material.

        Telephonics, which sells directly and indirectly to the U.S. government, is subject to certain regulations, laws and standards set by the U.S. government. Additionally, Telephonics is subject to routine audits and investigations by U.S. Government Agencies such as the Defense Contract Audit Agency and other Inspectors General. These agencies review a contractor's performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. These agencies also review the adequacy of, and a contractor's compliance with, its internal control systems and policies, including the contractor's management, purchasing, property, estimating, compensation, and accounting and information systems.

Seasonality

        Historically, Griffon's revenue and earnings are lowest in its second quarter and highest in its fourth quarter. With the inclusion of ATT, revenue and earnings are expected to be lowest in the first and second quarters, and highest in the third and fourth quarters.

Financial Information About Geographic Areas

        Segment and operating results are included in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

        For geographic financial information, see the Business Segment footnote in the Notes to Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data.

        Griffon's non-U.S. businesses are primarily in Germany, Canada, Brazil, Mexico, Australia and Sweden.

Research and Development

        Griffon's companies are encouraged to improve existing products as well as develop new products to satisfy customer needs; expand revenue opportunities; maintain or extend competitive advantages; increase market share and reduce production costs. Research and development costs, not recoverable under contractual arrangements, are charged to expense as incurred. Research and development costs for Griffon were $21.4 million in 2010, $17.8 million in 2009 and $17.5 million in 2008. ATT research and development costs, which are not included in the results of Griffon Corporation, were $1.6 million in 2010.

Intellectual Property

        Trademarks are considered to be of importance to Griffon's business. Griffon follows a practice of seeking trademark protection in the U.S. and throughout the world where Griffon's products are sold. Principal global and regional trademarks include Clopay®, Ideal Door®, Holmes®, Ames®, True Temper®, Ames True Temper®, Garant®, Hound Dog®, Westmix and Dynamic Design™, UnionTools®, Razor-Back® Professional Tools and Jackson® Professional Tools. Griffon's rights in these trademarks endure for as long as they are used and registered.

Item 1A.    Risk Factors

        Griffon's business, financial condition, operating results and cash flows can be impacted by a number of factors which could cause Griffon's actual results to vary materially from recent or anticipated future results. The risk factors discussed in this section should be carefully considered with all of the information in this Annual Report on Form 10-K. These risk factors should not be considered the only risk factors facing Griffon. Additional risks and uncertainties not presently known or that are currently deemed immaterial may also materially impact Griffon's business, financial condition, operating results and cash flows in the future.

15

        In general, Griffon is subject to the same general risks and uncertainties that impact other diverse manufacturing companies including, but not limited to, general economic, industry and/or market conditions and growth rates; impact of natural disasters and their effect on global markets; continued events in the Middle East and possible future terrorist threats and their effect on the worldwide economy; and changes in laws or accounting rules. Griffon has identified the following specific risks and uncertainties that it believes has the potential to materially affect its business and financial condition.

Acquisition of Ames True Temper, Inc.

        On September 30, 2010, Griffon purchased all of the outstanding stock of the parent company of ATT for total consideration of $542 million, subject to certain adjustments.

        Griffon will face risks commonly encountered with a substantial acquisition and related financing including:

•

Griffon may have failed to identify material problems and liabilities in its due diligence review;



•

Griffon may fail to successfully integrate certain aspects of the operations, administrative functions and personnel of ATT;



•

Griffon has a lean corporate senior management team which could be distracted by the time and commitment required in connection with the integration of ATT;



•

risks associated with expanding into new geographic regions such as the Far East and Australia, including new business cultures and new regulatory environments;



•

Griffon may fail to maintain good relationships with employees, suppliers and customers of ATT following the change in ownership; and



•

the additional indebtedness incurred to fund the acquisition of ATT could adversely affect Griffon's liquidity and financial stability.

Current worldwide economic uncertainty and market volatility could adversely affect Griffon's businesses.

        The current worldwide economic uncertainty, market volatility and credit crisis will continue to have an adverse effect on Griffon during 2011, particularly in Home & Building Products, which is substantially linked to the U.S. housing market and the general U.S. economy. Also, purchases of ATT products are discretionary for consumers and consumers are generally more willing to purchase products during periods in which favorable macroeconomic conditions prevail. Additionally, the current condition of the credit markets could impact Griffon's ability to refinance expiring debt, obtain additional credit for investments in current businesses or for acquisitions, with favorable terms, or there may be no financing available. Griffon is also exposed to basic economic risks including a decrease in the demand for the products and services offered or a higher risk of default on its receivables.

Adverse trends in the housing sector and in general economic conditions will directly impact Griffon's business.

        Home & Building Products' business is influenced by market conditions for new home construction and renovation of existing homes. For the year ended September 30, 2010, approximately 30% of Griffon's consolidated revenue was derived from the Home & Building Products segment (48% on a pro forma basis) which is heavily dependent on new home construction and renovation of existing homes. The strength of the U.S. economy, the age of existing home stock, job growth, interest rates, consumer confidence and the availability of consumer credit, as well as demographic factors such as the migration into the United States and migration of the population within the United States also have an effect on Home & Building Products. In that respect, the significant downturn in the housing market has had an adverse effect on the operating results of Home & Building Products and this effect is likely to continue in 2011, particularly to its CBP business.

16

Griffon operates in highly competitive industries and may be unable to compete effectively.

        Griffon's operating companies face intense competition in each of the markets served. There are a number of competitors, some of which are larger and have greater resources than Griffon's operating companies. Griffon competes primarily on the basis of competitive prices, technical expertise, product differentiation, and quality of products and services. There can be no assurance that Griffon will not encounter increased competition in the future, which could have a material adverse effect on Griffon's financial results.

The loss of large customers can harm financial results.

        A small number of customers account for, and are expected to continue to account for, a substantial portion of consolidated revenue. Approximately 18% of consolidated revenue and 50% of the Plastics segment revenue for the year ended September 30, 2010 was generated from P&G, the largest customer in the Plastics segment. Home Depot, Lowes and Menards are significant customers of Home & Building Products with Home Depot accounting for approximately 13% of proforma consolidated revenue of $1.7 billion and 27% of the proforma Home & Building Products segment revenue of $833 million for the year ended September 30, 2010. The U.S. Government and its agencies, Lockheed Martin Corporation and the Boeing Company, are significant customers of Telephonics. Future operating results will continue to substantially depend on the success of Griffon's largest customers, as well as Griffon's relationship with them. Orders from these customers are subject to fluctuation and may be reduced materially due to changes in these customers' needs. Any reduction or delay in sales of products to one or more of these customers could significantly reduce Griffon's revenue. Griffon's operating results will also depend on successfully developing relationships with additional key customers. Griffon cannot assure that Griffon's largest customers will be retained or that additional key customers will be recruited. Also, Home & Building Products extends credit to its customers, which exposes it to credit risk. Their largest customer accounted for approximately 26% and 10% of Home & Building Products' and Griffon's net accounts receivable as of September 30, 2010, respectively. If this customer were to become insolvent or otherwise unable to pay, the financial condition, results of operations and cash flows of the Home & Building Products segment would be adversely affected.

Reliance on third party suppliers and manufacturers may impair ability to meet ATT's customer demands.

        ATT relies on a limited number of domestic and foreign companies, including its joint venture partners, to supply components and manufacture certain of its products. The percentage of ATT's products sourced, based on revenue, approximated 41% in 2010. Reliance on third party suppliers and manufacturers may reduce control over the timing of deliveries and quality of ATT's products. Reduced product quality or failure to deliver products quickly may jeopardize relationships with certain of ATT's key customers. In addition, reliance on third party suppliers or manufacturers may result in failure to meet ATT's customer demands. Continued turbulence in the worldwide economy may affect the liquidity and financial condition of ATT's suppliers. Should any of these parties fail to manufacture sufficient supply, go out of business or discontinue a particular component, alternative suppliers may not be found in a timely manner, if at all. Such events could impact ATT's ability to fill orders, which would have a material adverse effect on customer relationships.

If Griffon is unable to obtain raw materials for products at favorable prices it could adversely impact operating performance.

        Home & Building Products' and Plastics' suppliers primarily provide resin, wood and steel. Assurance cannot be provided that these segments may not experience shortages of raw materials or components for products or be forced to seek alternative sources of supply. If temporary shortages due to disruptions in supply caused by weather, transportation, production delays or other factors require raw materials to be secured from sources other than current suppliers, the terms may not be as

17

favorable as current terms or material may not be available at all. In recent years, Home & Building Products and Plastics have experienced price increases in steel and plastic resins.

        While most key raw materials used in Griffon's businesses are generally available from numerous sources, raw materials are subject to price fluctuations. Because raw materials in the aggregate constitute a significant component of the cost of goods sold, price fluctuations could have a material adverse effect on Griffon's results of operations. Griffon's ability to pass raw material price increases to customers is limited due to supply arrangements and competitive pricing pressure, and there is generally a time lag between increased raw material costs and implementation of corresponding price increases for Griffon's products. In particular, sharp increases in raw material prices are more difficult to pass through to customers and may negatively affect short-term financial performance.

ATT is subject to risks associated with its operations in China.

        A substantial amount of ATT's sourcing is done through Chinese joint ventures. China does not have a well-developed, consolidated body of laws governing foreign investment enterprises. Enforcement of existing laws or contracts based on existing law may be uncertain and sporadic, and it may be difficult to obtain swift and equitable enforcement or to obtain enforcement of a judgment by a court of another jurisdiction. The relative inexperience of China's judiciary in many cases creates additional uncertainty as to the outcome of any litigation. In addition, interpretation of statutes and regulations may be subject to government policies reflecting domestic political changes. Furthermore, a substantial portion of ATT's pruning tools, as well as all foam and fiberglass planters, are manufactured in China and must be shipped into the U.S. When they enter the U.S., these products may be subject to import quotas, import duties and other restrictions. Any inability to import these products into the U.S. and any tariffs that may be levied with respect to these products may have a material adverse result on ATT's business and results of operations, financial position and cash flows.

Griffon's businesses are subject to seasonal variations and the impact of uncertain weather patterns.

        Historically, Griffon's revenue and income have been lowest in the second quarter ending March 31 and highest in the fourth quarter ending September 30, primarily due to the seasonality of CBP's business. CBP's revenue is driven by residential renovation and construction which is generally at reduced levels during the winter months. Because a high percentage of manufacturing overhead and operating expenses are relatively fixed throughout the year, operating margins have historically been lower in quarters with lower revenue. ATT's lawn and garden products are used primarily in the spring and summer; in 2010, 61% of ATT's sales occurred during the second and third quarters. A majority of ATT's operating income and cash flow is generated in this period, and therefore ATT's working capital needs and borrowings generally peak near the end of the second quarter in preparation for the spring selling season.

        With the inclusion of ATT's operating results, starting in 2011, the first and second quarters are expected to be Griffon's lower revenue and income quarters.

        Demand for lawn and garden products is influenced by weather, particularly weekend weather during the peak gardening season. ATT's sales volumes could be adversely affected by certain weather patterns such as unseasonably cool or warm temperatures, hurricanes, water shortages or floods. In addition, lack of snow or lower than average snowfall during the winter season may also result in reduced sales of certain ATT products, such as snow shovels and other snow tools. As a result, ATT's results of operations, financial results and cash flows could be adversely impacted.

Further consolidation in the retail industry may adversely affect profitability.

        Home centers and mass merchandisers have consolidated and increased in scale. If this trend continues, customers will likely seek more favorable terms for their purchases of products, which will limit Griffon's ability to pass through raw material or other cost increases, or to raise prices for any

18

reason. Sales on terms less favorable than current terms could have a material adverse effect on profitability.

Unionized employees could strike or participate in a work stoppage.

        Griffon employs approximately 5,700 people on a full-time basis, approximately 9% of whom are covered by collective bargaining or similar labor agreements (all in the Telephonics and ATT businesses). If unionized employees engage in a strike or other work stoppage, or if Griffon is unable to negotiate acceptable extensions of agreements with labor unions, a significant disruption of operations and increased operating costs could occur. In addition, any renegotiation or renewal of labor agreements could result in higher wages or benefits paid to unionized employees, which could increase operating costs and could have a material adverse effect on profitability.

Griffon may be required to record impairment charges for goodwill and indefinite-lived intangible assets.

        Griffon is required to assess goodwill and indefinite-lived intangible assets annually for impairment or on an interim basis if changes in circumstances or the occurrence of events suggest impairment exists. If impairment testing indicates that the carrying value of reporting units or indefinite-lived intangible assets exceeds the respective fair value, an impairment charge would be recognized. If goodwill or indefinite-lived intangible assets were to become impaired, the results of operations could be materially and adversely affected.

Trends in the baby diaper market will directly impact Griffon's business.

        Recent trends have been for baby diaper manufacturers to specify thinner plastic films for use in their products which reduces the amount of product sold and Plastics' revenue; this trend has generally resulted in Plastics incurring costs to redesign and reengineer products to accommodate required specification changes. Such decreases, or the inability to meet changing customer specifications, could result in a material decline in Plastics revenue and profits.

Telephonics' business depends heavily upon government contracts and, therefore, the defense budget.

        Telephonics sells products to the U.S. government and its agencies both directly, and indirectly as a first-tier supplier to prime contractors in the defense industry such as Boeing, Lockheed Martin and Northrop Grumman. In the year ended September 30, 2010, U.S. government contracts and subcontracts accounted for approximately 24% of Griffon's consolidated revenue. Contracts involving the U.S. government may include various risks, including:

•

termination for convenience by the government;



•

reduction or modification in the event of changes in the government's requirements or budgetary constraints;



•

increased or unexpected costs, causing losses or reduced profits under contracts where Telephonics' prices are fixed, or determinations that certain costs are not allowable under particular government contracts;



•

the failure or inability of the prime contractor to perform its contract in circumstances where Telephonics is a subcontractor;



•

failure to observe and comply with government business practice and procurement regulations such that Telephonics could be suspended or barred from bidding on or receiving awards of new government contracts;



•

the failure of the government to exercise options for additional work provided for in contracts; and



•

the government's right, in certain circumstances, to freely use technology developed under these contracts.

19

        The programs in which Telephonics participates may extend for several years, but are normally funded on an incremental basis. Decreases in the U.S. defense budget, in particular with respect to programs to which Telephonics supplies materials, could have a material adverse impact on Telephonics financial conditions, results of operations and cash flows. The U.S. government may not continue to fund programs to which Telephonics' development projects apply. Even if funding is continued, Telephonics may fail to compete successfully to obtain funding pursuant to such programs.

Telephonics' business could be adversely affected by a negative audit by the U.S. Government

        As a government contractor, and a subcontractor to government contractors, Telephonics is subject to audits and investigations by U.S. Government Agencies such as the Defense Contract Audit Agency, other Inspectors General and the Department of Justice. These agencies review a contractor's performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. These agencies also review the adequacy of, and a contractor's compliance with, its internal control systems and policies, including the contractor's management, purchasing, property, estimating, compensation, and accounting and information systems. Any costs found to be misclassified or improperly allocated to a specific contract will not be reimbursed or must be refunded if already billed and collected. Griffon could incur significant expenses in complying with audits and subpoenas issued by the government in aid of inquiries and investigations. If an audit or an investigation uncovers improper or illegal activities, Telephonics may be subject to civil and criminal penalties and/or administrative sanctions, which could include contract termination, forfeiture of profit, suspension of payments, fines and suspension or prohibition from doing business with the U.S. Government. In addition, if allegations of impropriety are made, Telephonics and Griffon could suffer serious reputational harm.

Griffon's companies must continually improve existing products, design and sell new products and invest in research and development in order to compete effectively.

        The markets for Plastics and Telephonics are characterized by rapid technological change, evolving industry standards and continuous improvements in products. Due to constant changes in these markets, future success depends on their ability to develop new technologies, products, processes and product applications.

        Product and technological developments are accomplished both through internally-funded research and development projects, as well as through strategic partnerships with customers. Because it is not generally possible to predict the amount of time required and costs involved in achieving certain research and development objectives, actual development costs may exceed budgeted amounts and estimated product development schedules may be extended. Griffon's financial condition and results of operations may be materially and adversely affected if:

•

product improvements are not completed on a timely basis;



•

new products are not introduced on a timely basis or do not achieve sufficient market penetration;



•

there are budget overruns or delays in research and development efforts; or



•

new products experience reliability or quality problems.

Griffon may be unable to implement its acquisition growth strategy, which may result in added expenses without a commensurate increase in revenue and income and divert management's attention.

        Making strategic acquisitions is a significant part of Griffon's growth plans. The ability to successfully complete acquisitions depends on identifying and acquiring, on acceptable terms, companies that either complement or enhance currently held businesses or expand Griffon into new profitable businesses. Additionally, Griffon must properly integrate acquired businesses in order to maximize profitability. The competition for acquisition candidates is intense and Griffon cannot assure that it will

20

successfully identify acquisition candidates and complete acquisitions at reasonable purchase prices, in a timely manner or at all. Further, there is a risk that acquisitions will not be properly integrated into Griffon's existing structure. In implementing an acquisition growth strategy, the following may be encountered:

•

costs associated with incomplete or poorly implemented acquisitions;



•

expenses, delays and difficulties of integrating acquired companies into Griffon's existing organization;



•

dilution of the interest of existing stockholders; or



•

diversion of management's attention.

        An unsuccessful implementation of Griffon's acquisition growth strategy could have an adverse impact on Griffon's results of operations, cash flows and financial condition.

The loss of certain key officers or employees could adversely affect Griffon's business.

        The success of Griffon is materially dependent upon the continued services of certain key officers and employees. The loss of such key personnel could have a material adverse effect on Griffon's operating results or financial condition.

Griffon is exposed to a variety of risks relating to non-U.S. sales and operations, including non-U.S. economic and political conditions and fluctuations in exchange rates.

        Griffon and its companies own properties and conduct operations in Europe, Canada, Australia, Mexico and South America. Sales of products through non-U.S. subsidiaries accounted for approximately 32% of consolidated revenue for the year ended September 30, 2010. These sales could be adversely affected by changes in political and economic conditions, trade protection measures, differing intellectual property rights laws and changes in regulatory requirements that restrict the sales of products or increase costs. Currency fluctuations between the U.S. dollar and the currencies in the non-U.S. regions in which Griffon does business may also have an impact on future reported financial results. Including ATT, on a pro forma basis, non-U.S. sales were approximately 29% of total Griffon sales.

Griffon may not be able to protect its proprietary rights.

        Griffon relies on a combination of patent, copyright and trademark laws, trade secrets, confidentiality and non-disclosure agreements and other contractual provisions to protect proprietary rights. Such measures do not provide absolute protection and Griffon cannot give assurance that measures for protecting these proprietary rights are and will be adequate, or that competitors will not independently develop similar technologies.

Griffon may inadvertently infringe on, or may be accused of infringing on, proprietary rights held by another party.

        Griffon is regularly improving its technology and employing existing technologies in new ways. Though Griffon takes reasonable precautions to ensure it does not infringe on the rights of others, it is possible that Griffon may inadvertently infringe on, or may be accused of infringing on, proprietary rights held by others. If Griffon is found to have infringed on the propriety rights held by others, any related litigation or settlement relating to such infringement may have a material effect on Griffon's financial statements and financial condition.

Griffon is exposed to product liability claims.

        Griffon may be the subject of product liability claims relating to the performance of its products or the performance of a product in which its products were a component part. There can be no assurance

21

that future product liability claims will not be brought against Griffon, either by an injured customer of an end product manufacturer who used one of the products as a component or by a direct purchaser. Moreover, no assurance can be given that indemnification from customers or coverage under insurance policies will be adequate to cover future product liability claims against Griffon. In addition, product liability insurance can be expensive, difficult to maintain and may be unobtainable in the future on acceptable terms. The amount and scope of any insurance coverage may be inadequate if a product liability claim is successfully asserted. Furthermore, if any significant claims are made, the business and the related financial condition of Griffon may be adversely affected by negative publicity.

Griffon has been, and may in the future be, subject to claims and liabilities under environmental laws and regulations.

        Griffon's operations and assets are subject to environmental laws and regulations pertaining to the discharge of materials into the environment, the handling and disposal of wastes, including solid and hazardous wastes, or otherwise relating to health, safety and protection of the environment, in various jurisdictions in which it operates. Griffon does not expect to make any expenditure with respect to ongoing compliance with or remediation under these environmental laws and regulations that would have a material adverse effect on its business, operating results or financial condition. However, the applicable requirements under environmental laws and regulations may change at any time.

        Griffon can incur environmental costs related to sites that are no longer owned or operated, as well as third-party sites to which hazardous materials are sent. It cannot be assured that material expenditures or liabilities will not be incurred in connection with such claims. See the Commitment and Contingencies footnote in the Notes to Consolidated Financial Statements for further information on environmental contingencies. Based on facts presently known, the outcome of current environmental matters are not expected to have a material adverse effect on Griffon's results of operations and financial condition. However, presently unknown environmental conditions, changes in environmental laws and regulations or other unanticipated events may give rise to claims that may involve material expenditures or liabilities.

Changes in income tax laws and regulations or exposure to additional income tax liabilities could adversely affect profitability.

        Griffon is subject to federal, state and local income taxes in the United States and in various taxing jurisdictions outside the United States. Tax provisions and liabilities are subject to the allocation of income among various U.S. and international tax jurisdictions. Griffon's effective tax rate could be adversely affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in any valuation allowance for deferred tax assets or the amendment or enactment of tax laws. The amount of income taxes paid is subject to audits by U.S. Federal, state and local tax authorities, as well as tax authorities in the taxing jurisdictions outside the United States. If such audits result in assessments different from recorded income tax liabilities, Griffon's future financial results may include unfavorable adjustments to its income tax provision.

Compliance with restrictions and covenants in Griffon's debt agreements may limit its ability to take corporate actions and harm its business.

        The credit agreements entered into by certain of Griffon's subsidiaries contain covenants that restrict their ability to, among other things, incur additional debt, pay dividends, incur liens and make investments, acquisitions, dispositions, restricted payments and capital expenditures. Under the respective credit agreements, these subsidiaries are also required to comply with specific financial ratios and tests. These subsidiaries may not be able to comply in the future with these covenants or restrictions as a result of events beyond their control, such as prevailing economic, financial and industry conditions or a change in control of Griffon. If a subsidiary defaults in maintaining compliance with the covenants and restrictions in its credit agreement, its lenders could declare all of the principal and interest amounts outstanding due and payable and terminate their commitments to extend credit to

22

the subsidiary in the future. If the subsidiary or Griffon is unable to secure credit in the future, business could be harmed.

Reported earnings per share may be more volatile because of the conversion contingency provision of the notes.

        The outstanding convertible notes are convertible when a "market price" condition is satisfied and also upon the occurrence of other circumstances as more fully described in the Notes Payable, Capitalized Leases and Long-Term Debt footnote in the Notes to Consolidated Financial Statements. Upon conversion, at Griffon's discretion, note holders will receive $1,000 in cash for each $1,000 principal amount of notes presented for conversion or value in Griffon's common stock, and Griffon common stock for the value above the principal amount of the notes. The potential shares of Griffon common stock issuable for value above the principal value of the notes are considered in the calculation of diluted earnings per share and volatility in Griffon's stock price could cause these notes to be dilutive in one quarter and not in a subsequent quarter, increasing the volatility of fully diluted earnings per share.

Griffon may be unable to raise additional financing if needed

        Griffon may need to raise additional financing in the future in order to implement its business plan, refinance debt, or to acquire new or complimentary businesses or assets. Any required additional financing may be unavailable, or only available at unfavorable terms, due to uncertainties in the credit markets. If Griffon raises additional funds by issuing equity securities, current holders of its common stock may experience significant ownership interest dilution and the new securities may have rights senior to the rights associated with current outstanding common stock.

Griffon's indebtedness and interest expense could limit cash flow and adversely affect operations and Griffon's ability to make full payment on outstanding debt.

        Griffon's indebtedness poses potential risks such as:

•

a substantial portion of cash flows from operations could be used to pay principal and interest on debt, thereby reducing the funds available for working capital, capital expenditures, acquisitions, product development and other general corporate purposes;



•

insufficient cash flows from operations may force Griffon to sell assets, or seek additional capital, which Griffon may not be able to accomplish on favorable terms, if at all; and



•

the level of indebtedness may make Griffon more vulnerable to economic or industry downturns.

Griffon has the ability to issue additional equity securities, which would lead to dilution of issued and outstanding common stock.

        The issuance of additional equity securities or securities convertible into equity securities would result in dilution to existing stockholders' equity interests. Griffon is authorized to issue, without stockholder vote or approval, 3,000,000 shares of preferred stock in one or more series, and has the ability to fix the rights, preferences, privileges and restrictions of any such series. Any such series of preferred stock could contain dividend rights, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences or other rights superior to the rights of holders of Griffon's common stock. There is no present intention of issuing any such preferred stock, but Griffon reserves the right to do so in the future. In addition, Griffon is authorized to issue, without stockholder approval, up to 85,000,000 shares of common stock, of which approximately 62,113,293 shares, net of treasury shares, were outstanding as of September 30, 2010. Additionally, Griffon is authorized to issue, without stockholder approval, securities convertible into either shares of common stock or preferred stock.
