Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

At-The-Market financial
"At-The-Market (“ATM”) equity offering programs"
"At-the-market" is a method for companies to sell new shares of stock directly into the open market over time, rather than all at once. It allows companies to raise money gradually, similar to selling slices of a pie instead of the entire pie at once, which can help manage the sale's impact on the stock price. This approach gives investors a steady supply of shares while providing companies with flexible funding options.
shelf registration statement regulatory
"expiration of the shelf registration statement"
A shelf registration statement is a document a company files with regulators that allows it to sell shares or bonds quickly when it’s a good time to raise money. It’s like having a pre-approved plan ready so the company can act fast without going through lengthy paperwork each time they want to sell, making fundraising more flexible.

Forward-Looking Statements

Matters discussed in this press release may constitute forward looking statements. The Private Securities Litigation Reform Act of 1995 provides safe harbor protections for forward-looking statements in order to encourage companies to provide prospective information about their business. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, shareholder return targets and underlying assumptions and other statements, which are other than statements of historical facts.

We desire to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and are including this cautionary statement in connection with this safe harbor legislation. Words such as, but not limited to, “believe,” “expect,” “anticipate,” “estimate,” “intend,” “plan,” “targets,” “projects,” “likely,” “will,” “would,” “could,” “should,” “may,” “forecasts,” “potential,” “continue,” “possible” and similar expressions or phrases may identify forward-looking statements.

The forward-looking statements in this press release are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, examination by our management of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections.


In addition, other important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include general dry bulk shipping market conditions, including fluctuations in charter rates and vessel values; the strength of world economies; the stability of Europe and the Euro; fluctuations in currencies, interest rates and foreign exchange rates; business disruptions due to natural and other disasters or otherwise, such as the impact of any future epidemics; the length and severity of epidemics and pandemics and their impact on the demand for seaborne transportation in the dry bulk sector; changes in supply and demand in the dry bulk shipping industry, including the market for our vessels and the number of new buildings under construction; the potential for technological innovation in the sector in which we operate and any corresponding reduction in the value of our vessels or the charter income derived therefrom; changes in our expenses, including bunker prices, dry docking, crewing and insurance costs; changes in governmental rules and regulations or actions taken by regulatory authorities; the impact of current and potential additional trade tariffs on global trade and demand for dry bulk shipping; the risk that trade disputes between U.S. and Chinese officials could result in the reimplementation of significant port fees that may impact our fleet; potential liability from pending or future litigation and potential costs due to environmental damage and vessel collisions; the impact of increasing scrutiny and changing expectations from investors, lenders, charterers and other market participants with respect to our Environmental, Social and Governance (“ESG”) practices; our ability to carry out our ESG initiatives and thereby meet our ESG goals and targets; new environmental regulations and restrictions, whether at a global level stipulated by the International Maritime Organization, and/or regional/national imposed by regional authorities such as the European Union or individual countries; potential cyber-attacks which may disrupt our business operations; general domestic and international political conditions or events, including, among others, “trade wars”, the ongoing conflict between Russia and Ukraine, the conflict between Israel and Hamas, the conflict between the United States, Israel and Iran and the attacks in the Strait of Hormuz, the Red Sea and the Gulf of Aden; the impact on our common shares and reputation if our vessels were to call on ports located in countries that are subject to restrictions imposed by the U.S. or other governments; our ability to successfully compete for, enter into and deliver our vessels under time charters or other employment arrangements for our existing vessels after our current charters expire and our ability to earn income in the spot market; potential physical disruption of shipping routes due to accidents, climate-related reasons (acute and chronic), political events, public health threats, international hostilities and armed conflicts, piracy or acts by terrorists; the availability of financing and refinancing; the failure of our contract counterparties to meet their obligations; our ability to meet requirements for additional capital and financing to complete our newbuilding program and grow our business; the impact of our indebtedness and the compliance with the covenants included in our debt agreements; vessel breakdowns and instances of off-hire; potential exposure or loss from investment in derivative instruments; potential conflicts of interest involving our Chief Executive Officer, his family and other members of our senior management; our ability to complete acquisition transactions or secondhand vessel purchases as and when planned and upon the expected terms; and the impact of port or canal congestion or disruptions. Please see our filings with the Securities and Exchange Commission for a more complete discussion of these and other risks and uncertainties. The information set forth herein speaks only as of the date hereof, and the Company disclaims any intention or obligation to update any forward-looking statements as a result of developments occurring after the date of this communication.
