ACCO BRANDS CORP

As a result of this seasonality, our inventory and working capital needs fluctuate significantly throughout the year. In addition, our customers often change their order patterns for peak seasons, making forecasting of production schedules and inventory purchases more challenging. These fluctuations have impacted our ability to accurately forecast our inventory and working capital needs as well as our operating results. When we are unable to accurately forecast and prepare for customer orders or our working capital needs, or if there is a downturn in business or economic conditions during these periods, our business,

results of operations, liquidity and financial condition have been, and in the future could be, adversely affected. Additionally, because of these quarterly fluctuations, comparisons of our operating results across different fiscal quarters may not be meaningful.

The level of investment returns on pension plan assets and the assumptions used for valuation purposes have affected the Company's earnings and could affect the Company’s earnings and cash flows in future periods. Changes in government regulations, as well as the significant unfunded liabilities, including the unfunded liabilities of the U.S. multi-employer pension plan in which we are a participant, could also affect the Company’s pension plan expenses and funding requirements.

As of December 31, 2025, the Company had $122.8 million recorded as pension liabilities in its Consolidated Balance Sheet. Funding obligations are determined by government regulations and are measured each year based on the value of assets and liabilities on a specific date. When the financial markets do not provide the long-term returns that are expected, or discount rates increase the present value of liabilities, the Company has been, and in the future could be, required to make larger contributions and/or record higher non-cash expenses related to its pension liabilities. The markets can be very volatile, and therefore the Company’s estimate of future contribution requirements and/or non-cash expenses can change dramatically in relatively short periods of time. Similarly, changes in interest rates and legislation enacted by governmental authorities can impact the timing and amounts of contribution requirements and/or non-cash expenses. An adverse change in the funded status of our pension plans could significantly increase our required future contributions and/or non-cash expenses and adversely impact our liquidity.
