Interpret with caution. The disclosed customer shares sum to more than 100% and are not additive. The filing explains why:

"Total revenue for each customer is net of fees, cash discounts, and rebates directly allocable to that customer. Rebates paid to other entities are excluded; therefore, the combined value may exceed 100%."

Each is a separate customer disclosed individually — the figures are not sub-parts of the headline and may be measured against different revenue bases, so they are not additive.
