GSK Set to Trade Ex-Dividend; Dividend Sustainability Analysis
- Ex-Dividend Date Approaching: GSK's stock will trade ex-dividend on February 19, meaning investors purchasing after this date will miss the £0.18 per share dividend payable on April 9, which is crucial for dividend-seeking investors.
- Stable Dividend Yield: Last year, GSK paid a total dividend of £0.72 per share against a current share price of £21.65, resulting in a 3.3% yield, indicating stability in dividend payments despite limited future growth potential.
- Moderate Payout Ratio: With a payout ratio of 47%, GSK's dividends are supported by profits, and last year's dividends consumed 53% of free cash flow, suggesting a sustainable payment capability.
- Weak Earnings Growth: While earnings per share have grown at an average rate of 3.1% annually over the past five years, dividends have declined by an average of 3.2% per year over the last decade, indicating challenges in dividend growth that may affect long-term investor confidence.
