Shares of Okeanis Eco Tankers Corp (ECO) tumbled 6.67% in pre-market trading on Thursday, following the release of the company's first-quarter 2025 earnings report and dividend announcement. The significant drop reflects investors' disappointment with the company's financial performance and possibly the declared dividend amount.

Okeanis Eco Tankers reported adjusted earnings of $0.36 per share for Q1 2025, a sharp decline from $1.23 per share in the same quarter last year. While this figure beat the analyst forecast of $0.24 per share, it still represents a substantial year-over-year decrease. The company's revenue also fell by 27.9% to $80.15 million, although it surpassed the expected $74.57 million. The reported EBITDA for the quarter stood at $33.8 million, indicating a significant contraction in the company's profitability.

Adding to the earnings news, Okeanis Eco Tankers also declared a dividend of $0.32 per common share for Q1 2025. While maintaining a dividend payout, the amount may have fallen short of some investors' expectations, especially considering the company's reduced earnings. The combination of weaker financial results and the dividend announcement appears to have triggered a negative sentiment among investors, leading to the pre-market plunge in the stock price.
