What Changed

Risk factors · Nov 13, 2024 → Nov 19, 2025

39 added · 36 removed between the two most recent 10-Ks. The risks a company starts — or stops — disclosing are often the story.

Newly disclosed

While CPP has established certain suppliers outside of China and is in the process of developing additional suppliers outside of China, and has increased sourcing from several other countries in an effort to minimize the risks associated with sourcing from China, various tariff actions taken since January 2025 by the U.S. government relating to imports from other countries may increase the costs of shifting CPP’s supply chain away from China.
As a result of this assessment, during the third quarter of fiscal 2025, we recorded pre-tax, non-cash impairment charges of $136,612 and $107,000 related to Hunter Fan's goodwill and indefinite-lived intangible assets, respectively, which resulted in an aggregate decrease of $4.65 in our earnings per share for the year ended September 30, 2025.
Indicators of impairment were not present for the HBP reportable segment or the AMES reporting unit within the CPP reportable segment during the fiscal year ended September 30, 2025. 19 For the fiscal year ended September 30, 2024, the annual impairment testing did not result in any impairments to goodwill or indefinite-lived intangible assets.
The volatile nature of these tariff actions creates significant uncertainty about the financial and operational impact on CPP’s operating and financial performance and may hinder the ability of CPP to develop and implement sustainable tariff mitigation strategies.
Changes in U.S. trade policy, including new tariffs and vessel fees for Chinese-built ships, as well as tariff-driven inventory surges, can disrupt international shipping, complicate import planning, and may result in delivery delays and increased costs, which could have an adverse impact on the business and financial results of HBP and CPP.
Griffon’s success may become increasingly dependent on its ability to effectively leverage AI to support its operational efficiencies, such as with respect to supply chain, logistical systems, product development and marketing capabilities.
Use of AI exposes Griffon to risks that the AI solutions used may be deficient, produce inaccurate or misleading output, become inoperable or subject Griffon to cybersecurity and data privacy breaches, all of which could lead to operational disruptions, flawed decision-making, increased costs, and difficulties improving product development and marketing through the use of AI, and could impact Griffon’s operational effectiveness and financial condition.
The global legal, regulatory, and ethical landscape surrounding AI is evolving rapidly and remains uncertain, which creates continued compliance risk and may increase the operational costs associated with Griffon’s use of AI, may limit Griffon’s ability to fully develop or use AI solutions as intended, and may cause legal repercussions and brand or reputational harm to Griffon. 21 Griffon is exposed to product liability and warranty claims.
Additionally, the use of certain AI solutions could put Griffon’s own information and intellectual property rights at risk or expose Griffon to the risk of infringing third parties’ intellectual property or other rights.
In January 2025, the U.S. issued the “America First Trade Policy,” pursuant to which the administration commenced a broad range of trade investigations that have resulted in the imposition of a series of significant tariffs on products from many countries around the world.
Because of the volume of sourcing by CPP from international locations, trade actions by the U.S. government since January 2025, as well as future trade actions, represent a continuing risk to CPP’s revenue and operating performance.
Griffon is also exposed to certain fundamental economic risks including a decrease in the demand for the products and services it offers or a higher likelihood of default on its receivables.

No longer disclosed

Griffon is also exposed to certain fundamental economic risks including a decrease in the demand for the products and services it offers or a higher likelihood of default on its receivables. 12 Adverse trends and general economic conditions, especially those that relate to construction and renovation, will impact Griffon’s business.
CPP’s expanded global sourcing strategy may also increase its exposure to cybersecurity risks, as discussed in the below risk factor titled “Griffon’s operations and reputation may be adversely impacted if our information technology (IT) systems, or the IT systems of third parties with whom we do business, fail to perform adequately or if we or such third parties are the subject of a data breach or cyber-attack." The adoption of an asset-light business model for these U.S. products has positioned CPP to better serve customers with a more flexible and cost-effective sourcing model that leverages supplier relationships around the world, which is in turn expected to improve CPP’s competitive positioning and financial performance.
Because of the volume of sourcing by CPP from China, the ongoing trade dispute between the U.S. and China, including the imposition of tariffs on various Chinese imports into the U.S. at various times since March 2018, represents a continuing risk to CPP revenue and operating performance.
The continuing political and economic conflicts between U.S. and China have resulted in, and may continue to result in retaliatory actions from, both countries, and it is unknown whether current US-China relations over Taiwan, including the signature of the US-Taiwan Initiative on 21 st Century Trade signed in May 2023, or the United States' continuing commitment to support Taiwan with equipment and services for its self-defense, will impact the ongoing trade dispute with China.
Department of Labor, the annual inflation rate for the United States decreased to 3.7% for the twelve months ended September 30, 2023, and it further decreased to 3.5% for the twelve months ended September 30, 2024.
In addition to continuing the tariffs rather than allowing them to terminate under the Trade Act, the USTR announced additional tariffs on a number of products, to be implemented over the two-year period 2024-2026.
Griffon announced in May 2023 that CPP was expanding its global sourcing strategy to include long handled tools, material handling, and wood storage and organization product lines for the U.S. market.
Griffon announced in May 2023 that CPP was expanding its global sourcing strategy to include long handled tools, material handling, and wood storage and organization product lines for the U.S. market.
As a result of this global sourcing expansion initiative, manufacturing operations have concluded at four manufacturing sites and four wood mills, resulting in a total its facility footprint reduction of approximately 1.2 million square feet, or approximately 15% of CPP's square footage, and a headcount reduction of approximately 600.
At September 30, 2024, Griffon employed approximately 5,300 people on a full-time basis, approximately 3% of whom are covered by collective bargaining or similar labor agreements.
In May 2024, the United States Trade Representative (USTR) completed a mandatory four-year review of the tariffs under Section 301 of the Trade Act of 1974.
This initiative was successfully completed as of September 30, 2024, ahead of the previously announced date of December 31, 2024.
