What Changed

Risk factors · Mar 13, 2025 → Mar 5, 2026

17 added · 5 removed between the two most recent 10-Ks. The risks a company starts — or stops — disclosing are often the story.

Newly disclosed

For example, President Trump imposed tariffs on foreign countries under the International Emergency Economic Powers Act (IEEPA) in 2025.
The Company has experienced, and is expected to continue to experience, a high tariff environment and inflationary pressures that have impacted its profit margins, primarily due to tariffs on raw materials (specifically, steel and aluminum).
Further, artificial intelligence tools are increasingly being used in our industry, and we are evaluating the use of such tools throughout our company.
While tariffs imposed under the International Emergency Economic Powers Act (IEEPA) in 2025 were ruled to be illegal in February 2026 by the U.S.
There are risks involved in developing and using artificial intelligence tools in our operations.
Further, to the extent amounts are refunded for previously paid tariffs that impacted the Company, it is unknown how such refunds would be processed or the timeline for doing so and whether any such amounts would be recovered by the Company.
Any such disruption could cause delays in the production and distribution of the Company’s products and the loss of sales and customers, particularly in regions where the Company maintains manufacturing operations or relies on cross border sourcing.
As such policy changes continue to be made, face legal challenges and court rulings, uncertainty remains as to how those changes will further impact our business and the business of our competitors over the long term, and the extent to which we will benefit from them or be negatively affected by them.
Use of artificial intelligence may increase these vulnerabilities, as well.
Labor shortages or increased labor-related costs have directly affected our results and, if they are significant or sustained, could adversely affect our results of operations and financial condition.
Failure to comply with any such legal requirements could subject the Company to monetary liabilities and other sanctions, which could harm its business, results of operations and financial condition.
Such developments underscore the pace of change and the potential for legal challenges and implementation uncertainty affecting the regulatory environment in which we operate.

No longer disclosed

Over the past few years, the Company has experienced temporary inflationary pressures that have impacted its profit margins, primarily due to raw materials increases (specifically, plastic resins, steel, aluminum, petroleum and sand (grit)), coupled with increased freight costs and tariffs.
Until we know what policy changes are made, whether those policy changes are challenged and subsequently upheld by the court system and how those changes impact our business and the business of our competitors over the long term, we will not know if, overall, we will benefit from them or be negatively affected by them.
Any such disruption could cause delays in the production and distribution of the Company’s products and the loss of sales and customers.
Labor shortages or increased labor-related costs could also directly affect our financial condition.
The Facility is currently scheduled to expire on March 2, 2026.
