STAR BULK AGREES TO ACQUIRE 34 DRYBULK VESSELS

ATHENS, GREECE – August 19, 2014 – Star Bulk Carriers Corp. ("Star Bulk" or the "Company") (NASDAQ: SBLK) announced today that it has entered into definitive agreements with Excel Maritime Carriers Ltd. ("Excel") pursuant to which the Company will acquire 34 operating vessels (the "Vessels") for an aggregate of 29.917 million shares of common stock of Star Bulk and $288.39 million in cash (the "Vessel Purchase Transactions").

Overview of the Vessel Purchase Transactions

Through the Vessel Purchase Transactions, the Company expects to acquire 34 secondhand drybulk carriers, consisting of 6 Capesize vessels, 14 sistership Kamsarmax vessels, 12 Panamax vessels and 2 Handymax vessels mainly built at shipyards in Japan. The Vessels will be acquired in a series of closings which the Company expects to complete by the end of 2014. The closings are expected to occur on a vessel-by-vessel basis, in general upon reaching port after their current voyages and cargoes are discharged.

Upon completion of the Vessel Purchase Transactions, Star Bulk's position as the largest U.S listed dry bulk company will be further enhanced, with a fleet of 103 vessels on a fully delivered basis and aggregate cargo-carrying capacity of approximately 11.85 million deadweight tons.

Star Bulk expects to use cash on hand, together with borrowings under a new $231 million secured bridge loan facility extended to the Company by entities affiliated with the Company's largest shareholder, Oaktree Capital Management, L.P. (the "Oaktree Investors"), and entities affiliated with Angelo Gordon & Co. (the "Angelo Gordon Investors"), both current Excel shareholders, to pay the cash portion of consideration in the Vessel Purchase Transactions. When the Vessel Purchase Transactions are completed, and the Star Bulk shares forming part of the consideration are distributed to Excel's shareholders, the Oaktree Investors would own 57.3% of Star Bulk's outstanding shares of common stock, and the Angelo Gordon Investors would own 7.8% of Star Bulk's outstanding shares of common stock. The Vessel Purchase Transactions have been approved by the disinterested members of the Board of Directors of the Company, based upon the recommendation of a transaction committee of disinterested directors established by the Board of Directors of the Company, which considered the Vessel Purchase Transactions on behalf of the Company in coordination with the Company's management team. The total consideration for the Vessel Purchase Transactions of $634.91 million was determined based on the average of three vessel appraisals by independent vessel appraisers.

Benefits of the Transaction, upon completion:

· Enhances Star Bulk as the largest U.S. listed dry bulk company with a fleet of 103 vessels on a fully delivered basis with an aggregate cargo-carrying capacity of approximately 11.85 million deadweight tons, including 39 Capesize and Newcastlemax vessels and 20 Kamsarmax vessels (including 14 sisterships).

· Provides greater commercial presence and additional economies of scale on technical operations.

· Increases the total market capitalization of the Company's common stock from $1.09 billion to $1.49 billion, assuming 29.917 million shares of common stock issued in the Vessel Purchase Transactions, at the August 18, 2014 closing share price of $13.12 per share.

Petros Pappas, Chief Executive Officer of Star Bulk Carriers Corp., commented: "We are excited to announce these vessel purchases that, when completed, will expand our presence as the largest U.S. listed drybulk shipping company, and one of the largest dry bulk owners and operators globally. These transactions mark an important next step in the evolution of Star Bulk following our recent merger transaction with Oceanbulk. We believe that these vessel purchases are accretive to earnings and cash flow per share. We also believe that after these transactions are completed, Star Bulk will be well positioned to capitalize on an improving dry bulk shipping market with significant operating leverage to rising rates. Furthermore, as with our recent merger transaction with Oceanbulk, these transactions will preserve our cash resources, as it will be funded primarily with new equity determined on a net asset value to net asset value basis and a bridge loan from Oaktree and Angelo Gordon. This is consistent with our strategy to be an active consolidator in the dry bulk shipping industry, using moderate levels of debt."

Seward & Kissel LLP is serving as legal counsel to Star Bulk in connection with the Transaction, Paul, Weiss, Rifkind, Wharton & Garrison LLP is serving as counsel to Excel and to the Oaktree Investors, Willkie, Farr & Gallagher LLP is serving as counsel to the special committee of Excel's Board of Directors and to the Angelo Gordon Investors.
