Other income (expense), net increased by $13 million or 260%, for the three months ended September 30, 2025 compared to the three months ended September 30, 2024. The increase was primarily driven by $7 million interest income related to an AMITC refund, $7 million gains on fair value changes primarily related to equity securities, offset by $2 million higher foreign exchange currency losses.

Other income (expense), net increased by $57 million or 518.2%, for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. The increase was primarily due to a $31 million step-acquisition of the remaining equity interest of a joint venture, a nonrecurring gain of $24 million recognized in connection with the liquidation of one of the Company's manufacturing plants and $12 million higher gains on equity investments. This was partially offset by a $9 million contingency loss.
