Notes:

We evaluate the performance of our non-U.S. dollar functional currency international operations based on fixed currency exchange rates, which eliminate the impact of exchange rate fluctuations on our international operations. Fixed currency amounts are updated annually at the beginning of each year based on translation into U.S. dollars at foreign currency exchange rates established by management, with all periods presented using such rates. The "Fixed Currency Rate Change” columns in the table above reflect international operations at fixed currency exchange rates established by management at the beginning of 2026, rather than the 2025 established rates. The difference between the fixed currency exchange rates and the actual currency exchange rates is reported within the "Effect of foreign currency translation" rows in the table above for net sales and operating income.

The “Other” columns in the table above reflect immaterial changes between reportable segments, including the movement of certain customers and cost allocations.

The above table includes financial measures that have not been calculated in accordance with accounting principles generally accepted in the U.S. (“GAAP”), including fixed currency sales, fixed currency cost of sales, fixed currency selling, general and administrative expenses, fixed currency special (gains) and charges, and fixed currency operating income. We provide these measures as additional information regarding our operating results. We use these non-GAAP measures internally to evaluate our performance and in making financial and operational decisions, including with respect to incentive compensation. We believe that our presentation of these measures provides investors with greater transparency with respect to our results of operations and that these measures are useful for period-to-period comparison of results.

These non-GAAP financial measures are not in accordance with, or an alternative to, GAAP and may be different from non-GAAP measures used by other companies. Investors should not rely on any single financial measure when evaluating our business. We recommend that investors view these measures in conjunction with the GAAP measures included in the table.

Mentions · how they’re counted

Category	Word counter	Model’s count
AI AI, artificial intelligence, generative AI, machine learning, large language model, LLM	—	—
Layoffs layoffs, RIF, headcount reduction, workforce optimization, restructuring	—	—
Recession recession, downturn, contraction, slowdown	—	—
Tariffs tariff, trade war, trade barriers, trade restrictions, trade policy	—	—
Buybacks share repurchase, buyback program	—	—

Underlines use the same word lists the scores use. AI, recession and tariffs follow Palanor’s word counter, so those counts match it exactly on the same text. Layoffs and buybacks use the terms the model was given. The model’s count is an estimate by meaning, not by string, so it can differ from the underlines.
