Key Decisions for Investors

• Investors seeking to capture the upcoming quarterly dividends must own shares of OTTR, MSEX, or SWX before the ex-dividend date of August 15, 2025.
• For income-focused portfolios, Southwest Gas Holdings presents the highest potential annualized yield of the trio at 3.11%, which may warrant a closer look relative to its peers.
• Traders should anticipate a mechanical price drop in these stocks at the market open on August 15, 2025, corresponding to their dividend yields, though the positive intraday performance indicates this may be met with buying interest.
• Long-term investors should verify the dividend history and underlying profitability of each company to assess the likelihood that these declared payouts will continue in the future.
