Are there any tax implications or foreign withholding considerations for shareholders receiving the September 10, 2025 dividend?

Tax & withholding overview

The September 10, 2025 cash dividend of $0.055 per share is treated as ordinary dividend income for U.S.‑based investors. Because the payout is modest and the company does not issue a qualified‑dividend designation, the amount is fully taxable at the shareholder’s ordinary income tax rate (subject to the 3.8 % Net Investment Income Tax for high‑‑income taxpayers). For most U.S. investors the after‑tax yield will be roughly $0.055 × (1 – marginal tax rate).

For non‑U.S. (foreign) shareholders, the United States imposes a statutory 30 % withholding tax on cash dividends unless a lower treaty rate applies. Most major tax treaties (e.g., with Canada, the U.K., Germany, Japan, etc.) reduce the rate to 15 % or 0 % for portfolio‑shareholders that do not hold a “substantial” interest (generally <10 % of the company). If the shareholder’s residence country has no treaty with the U.S., the full 30 % will be withheld at source. The net dividend received will therefore be $0.055 × (1 – withholding rate).

Trading implications

Because the dividend is small relative to the share price, the ex‑dividend price adjustment will be modest (≈$0.055). Traders should focus on the after‑tax yield when evaluating the attractiveness of the stock, especially for high‑tax‑bracket investors or those in jurisdictions with high withholding. If you are a foreign investor, verify your treaty eligibility and ensure the proper Form W‑8BEN is on file with your broker to capture the reduced rate; otherwise, the 30 % withholding will erode the dividend’s contribution to total return. In practice, the dividend increase (10 % YoY) is a positive signal for cash flow, but the market will likely price‑in the net after‑tax amount, so any long‑or short position should be sized with the post‑tax cash flow in mind rather than the gross $0.055 per share.
