Exhibit 99.1

STAR BULK CARRIERS CORP. ANNOUNCES THE SALE OF M/V STAR KIM

ATHENS, GREECE, December 22, 2014—Star Bulk Carriers Corp. (the “Company” or “Star Bulk”) (Nasdaq: SBLK) a global shipping company providing transportation solutions in the dry bulk sector, today announced that it has entered into a binding agreement to sell the M/V Star Kim (ex Princess I, the “Vessel”), a 38,858 dwt Handymax vessel, built in 1994, to a non-related third party (the “Buyers”). The Company expects to deliver the Vessel to the buyers by early February 2015 at the latest.

Star Kim was acquired from Excel Maritime Carriers Ltd (“ Excel ”) under an “en bloc” transaction of 34 vessels on August 19, 2014 and was delivered to the Company on December 5, 2014.

This transaction signals the beginning of Star Bulk’s strategy to divest from part of its older fleet vessels, while strengthening its balance sheet and improving its liquidity position.

The opportunistic sale of older assets coupled with the expected delivery of 35 fuel efficient newbuilding vessels in 2015 and 2016, will allow Star Bulk to operate a large, modern and diverse fleet serving a multitude of clients and transporting a variety of cargos across the globe.

Star Bulk was incorporated in the Marshall Islands on December 13, 2006 and maintains executive offices in Athens, Greece.

Our fleet currently includes 56 operating vessels, 12 second hand vessels to be delivered by December 31, 2014 and 35 newbuilding vessels currently under construction at shipyards in Japan and China.

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, and underlying assumptions and other statements, which are other than statements of historical facts.

The Company desires to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and is including this cautionary statement in connection with this safe harbor legislation. The words “believe,” “anticipate,” “intends,” “estimate,” “forecast,” “project,” “plan,” “potential,” “may,” “should,” “expect,” “pending” and similar expressions 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 the Company’s management of historical operating trends, data contained in its records and other data available from third parties. Although the Company believes 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 the Company’s control, the Company cannot assure you that it will achieve or accomplish these expectations, beliefs or projections.

In addition to these important factors, other important factors that, in the Company’s 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 charterhire rates and vessel values, the strength of world economies, the stability of Europe and the Euro, fluctuations in interest rates and foreign exchange rates, changes in demand in the dry bulk shipping industry, including the market for our vessels, changes in our operating expenses, including bunker prices, dry docking and insurance costs, changes in governmental rules and regulations or actions taken by regulatory authorities, potential liability from pending or future litigation, general domestic and international political conditions, potential disruption of shipping routes due to accidents or political events, the availability of financing and refinancing, our ability to meet requirements for additional capital and financing to complete our newbuilding program and grow our business, vessel breakdowns and instances of off-hire, risks associated with vessel construction, 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, and our ability to complete acquisition transactions as planned.  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.
