Exhibit 1

STAR BULK CARRIERS CORP. REPORTS FINANCIAL RESULTS
FOR THE SECOND QUARTER AND FIRST HALF 2012

AND DECLARES QUARTERLY DIVIDEND OF $0.015 PER SHARE

ATHENS, GREECE, August 29, 2012 – Star Bulk Carriers Corp. (the “Company” or “Star Bulk”) (Nasdaq: SBLK), a global shipping company focusing on the transportation of dry bulk cargoes, today announced that its Board of Directors declared a cash dividend of $0.015 per outstanding share of the Company's common stock for the three months ended June 30, 2012. The dividend is payable on or about September 18, 2012, to shareholders of record as of September 10, 2012. The Company also announced today its unaudited financial and operating results for the quarter ended June 30, 2012 and first half 2012.

Spyros Capralos, President and CEO of Star Bulk commented: "This quarter was one of the most challenging for our industry. The extremely weak freight environment and the off-hire related to the grounding and repairs of the Star Polaris negatively impacted Star Bulk’s performance this quarter.

We are pleased to have chartered-out the majority of our capesize vessels at above market levels. Our cost optimization strategy continues to produce tangible results, at a time when it is most needed. Operational efficiency is one of the most important assets for a company – especially during times of low freight rates.

Star Bulk’s Board of Directors has decided to reward the company’s shareholders with a quarterly dividend of $0.015 per share. This is the Company’s thirteenth consecutive dividend payment after the company reinstated it in 2009.

We remain optimistic on the long-term outlook for the dry bulk industry, especially as we move past this year’s extraordinarily high fleet growth. We expect 2012 to be a year of record high vessel deliveries. We are pleased that the majority of our Capesize vessels are chartered at above-market levels and to major reputable charterers and are thus, to a certain extent, immune to the current adverse freight environment. We continue to have confidence that demand for dry bulk commodities and dry bulk shipping from major developing countries will continue growing at healthy rates. We believe that Star Bulk’s operational efficiency puts the company among the better-positioned companies in the dry bulk industry that can overcome the challenge of low freight rates.”

Simos Spyrou, Chief Financial Officer of Star Bulk commented: "As of today, our outstanding debt amounts to $235.1 million with $8.9 million in principal repayment due for the remainder 2012. The Company has no scheduled balloon payments up until the fourth quarter of 2016. Our cash position yesterday stood at $38.6 million.

Despite the fact that our average vessel size for the second quarter 2012 increased by 39% in DWT terms compared to the same period last year, our daily operating expenses actually decreased by 11%, from $5,609 to $4,976.

I believe Star Bulk we will manage to find opportunities to further optimize our operational efficiency and grow our fleet.”

Second Quarter 2012 and 2011 Results

For the quarter ended June 30, 2012, total voyage revenues amounted to $21.7 million compared to $22.7 million for the quarter ended June 30, 2011. Operating loss amounted to $2.7 million for the quarter ended June 30, 2012 compared to operating income of $2.4 million for the quarter ended June 30, 2011. Net loss for the second quarter of 2012 amounted to $4.6 million or $0.056 loss per share calculated on 81,256,749 weighted average number of shares, basic and diluted. Net income for the second quarter of 2011 amounted to $1.7 million or $0.03 income per share calculated on 63,364,120 and 63,466,580 weighted average number of shares basic and diluted, respectively.

The second quarter of 2012 net loss figure includes the following non-cash items:

·

Amortization of fair value of above market acquired time charters of $1.6 million or $0.02 per basic and diluted share, associated with time charters attached to vessels acquired in 2011, which are amortized over the remaining period of the time charter as a decrease to voyage revenue.

·

Expenses of $0.1 million or $0.001 per basic and diluted share relating to the amortization of stock based compensation recognized in connection with the unvested restricted shares issued to directors and employees.

Excluding these non-cash items, net loss for the second quarter of 2012 would amount to $2.9 million or $0.04 loss per basic and diluted share.

The second quarter of 2011 net income figure includes the following non-cash items:

·

Expenses of $0.5 million or $0.008 per basic and diluted share relating to the amortization of stock based compensation recognized in connection with the unvested restricted shares issued to directors and employees.

·

An unrealized loss of $0.05 million associated with the mark to market valuation of the Company’s derivatives.

Excluding these non-cash items, net income for the second quarter of 2011 would amount to $2.3 million or $0.04 earnings per basic and diluted share.

Adjusted EBITDA for the second quarter of 2012 and 2011 excluding the above items was $8.4 million and $15.1 million, respectively. A reconciliation of EBITDA and adjusted EBITDA to net cash provided by cash flows from operating activities is set forth below.

An average of 14.0 and 11.0 vessels were owned and operated during the second quarter of 2012 and the second quarter of 2011, respectively, earning an average Time Charter Equivalent, (“TCE”) rate of $14,628 per day and $18,664 per day, respectively. We refer you to the information under the heading “Summary of Selected Data” later in this earnings release for further information regarding our calculation of TCE rates.

For the quarter ended June 30, 2012, vessel operating expenses totaled $6.7 million compared to $5.6 million for the same period of 2011. This increase is mainly due to the fact that the average number of vessels increased to 14.0 during the three months ended June 30, 2012 compared to 11.0 during the same period in 2011.

For the quarter ended June 30, 2012, dry-docking expenses totaled $0.9 million compared to $0.5 million for the quarter ended June 30, 2011. This increase is mainly due to the fact that one of our capesize vessels Star Mega underwent a periodic dry-docking survey in late June 2012. The amount of $0.9 million refers to a portion of the dry-docking cost for this vessel, which is estimated to reach $2.4 million in total. During the second quarter of 2011, one of our supramax vessels underwent for a dry-docking survey, with a total cost of $0.5 million.

Voyage expenses increased to $5.3 million for the quarter ended June 30, 2012 from $4.4 million for the quarter ended June 30, 2011. During the three months ended June 30, 2012, two of our vessels were under voyage charter agreements while during the three months ended June 2011 none of our vessels were under voyage charter agreement. The revenue earned from the respective voyage charter agreements was $4.7 million. An amount of $3.4 million included in voyage expenses during the second quarter of 2011 relates to the chartering-in a third party vessel to serve a shipment under a Contract of Affreightment (COA). The revenue earned from the COA, for the quarter ended June 30, 2011, amounted to $3.5 million.

General and administrative expenses decreased by $0.7 million, to $2.1 million during the quarter ended June 30, 2012 compared to $2.9 million during the quarter ended June 30, 2011. This decrease was mainly due to lower stock based compensation expenses by $0.4 million in the second quarter of 2012 compared to the same period in 2011. In addition the general and administrative expenses for the three months ended June 30, 2011 included a non-recurring severance payment of $0.5 million, to our former Chief Financial Officer (CFO) who resigned as our CFO and from our Board of Directors on August 31, 2011, pursuant to the terms of his employment and consultancy agreements.

Other operational gain amounting to $9.2 million during the quarter ended June 30, 2011 includes non-recurring revenue of $9.0 million received from the settlement of a commercial claim and a gain of $0.2 million regarding a hull and machinery claim. During the second quarter of 2012, no other operational gain was recorded.

Other operational loss amounting to $4.1 million during the second quarter of 2011, refers to the payment made by the Company to a third party, pursuant to the terms of the agreement that was signed in September of 2010, to sell a 45% interest in the future proceeds related to the settlement of certain of the commercial claims. The payment of $4.1 million was made in connection with the settlement of the $9.0 million commercial claim described in Other operational gain above. No other operational loss was recorded during the quarter ended June 30, 2012.

First Half 2012 and 2011 Results

For the first half of 2012, total voyage revenues amounted to $49.7 million compared to $52.2 million for the first half of 2011. This decrease was mainly due to lower charter rates for some of our vessels during 2012 compared to same period of 2011.In addition the total voyage revenues for the six month period ended June 30, 2012 are affected by the vessel’s Star Polaris grounding which resulted to an off-hire period of 48 days equating to a $0.8 million loss of revenue.

Operating loss amounted to $0.5 million for the first half of 2012 compared to operating income of $5.1 million for the first half of 2011. Net loss for the first half of 2012 amounted to $4.5 million representing $0.055 loss per basic and diluted share calculated on 80,780,384 weighted average number of shares, basic and diluted. Net income for the first half of 2011 amounted to $3.4 million representing $0.053 earnings per basic share calculated on 63,364,120 and 63,438,838 weighted average number of shares, basic and diluted, respectively.

The first half 2012 net income figure includes the following non-cash items:

·

Amortization of fair value of above market acquired time charters of $3.2 million or $0.04 per basic and diluted share, associated with time charters attached to vessels acquired in 2011, which are amortized over the remaining period of the time charter as a decrease to voyage revenue.

·

An unrealized gain of $0.1 million or $0.001 per basic and diluted share associated with the mark to market valuation of the Company’s derivatives.

Excluding these non-cash items, net income for the first half of 2012 would amount to $3.2 million or $0.04 income per basic and diluted share.

The first half 2011net income figure includes the following non-cash items:

·

An increase of revenue of $0.5 million or $0.007 per basic and diluted share, representing write off of remaining balance of deferred revenue related to fair value of below market acquired time charters attached to vessels acquired due to early redelivery of vessel Star Cosmo by its charterers, of which $0.2 million is included under Voyage revenue and $0.3 million is included under Gain on time charter agreement termination.

·

Expenses of $0.6 million or $0.01 per basic and diluted share, relating to the amortization of stock based compensation recognized in connection with the restricted shares issued to directors and employees.

·

An unrealized loss of $0.05 million associated with the mark to market valuation of the Company’s derivatives.

Excluding these non-cash items from net income for the first half of 2011 would amount to $3.6 million or $0.06 earnings per basic and diluted share.

Adjusted EBITDA for six months ended June 30, 2012 and 2011 was $26.4 million and $29.3 million respectively. A reconciliation of EBITDA and adjusted EBITDA to net cash provided by cash flows from operating activities is set forth below.

An average of 14.4 and 11.0 vessels were owned and operated during the six-month period ended June 30, 2012 and 2011, respectively, earning an average TCE rate of $15,724 and $20,943 per day, respectively. We refer you to the information under the heading "Summary of Selected Data" later in this earnings release for further information regarding our calculation of TCE rates.

Vessel operating expenses amounted to $14.2 million for the six-month period ended June 30, 2012 compared to $10.7 million for the six-month period ended June 30, 2011.The increase is mainly due to the fact that the average number of our vessels increased to 14.4 during the first half of 2012 compared to 11.0 during the same period of 2011.

Voyage expenses amounted to $14.0 million for the six-month period ended June 30, 2012 compared to $11.0 million for the six-month period ended June 30, 2011. The expense for chartering-in third party vessels to serve shipments under a Contract of Affreightment amounted to $4.1 million and $10.0 million for the six-month period ended June 30, 2012 and 2011 respectively. Excluding these expenses for chartering-in third party vessels, the increase in voyage expenses is mainly due to the fact that during the six-month period ended June 30, 2012 our vessels were under five voyage charter agreements while during the same period in 2011 none of our vessels was under voyage charter agreement. The revenue earned from the respective voyage charter agreements during the six-month period ended June 30, 2012 was $15.2 million.

General and administrative expenses were $5.3 million during the first half of 2012 compared to $7.0 million during the first half of 2011. The decrease in general and administrative expenses in six-month period ended June 30, 2012 is mainly due to the non-recurring severance payment to our former Chief Executive Officer and President and to our former CFO, in the first half of 2011, pursuant to the terms of their employment and consultancy agreements with the Company, totaling to $2.9 million offset by an increase of $0.8 million in stock based compensation expense during the first half of 2012 compared to the same period in 2011.

Gain on time charter agreement termination totaled $6.5 million for the six months ended June 30, 2012, representing a cash payment of $5.73 million and fuel oil valued at $0.72 million received as compensation for the early redelivery of vessel Star Sigma from its previous charterer.

(1)

Average number of vessels is the number of vessels that constituted our fleet for the relevant period, as measured by the sum of the number of days each vessel was a part of our fleet during the period divided by the number of calendar days in that period.

(2)

Average age of operational fleet is calculated as at June 30, 2012 and 2011, respectively.

(3)

Ownership days are the total calendar days each vessel in the fleet was owned by Star Bulk for the relevant period.

(4)

Available days for the fleet are the ownership days after subtracting for off-hire days with major repairs, dry-docking or special or intermediate surveys or transfer of ownership.

(5)

Voyage days are the total days the vessels were in our possession for the relevant period after subtracting all off-hire days incurred for any reason (including off-hire for dry-docking, major repairs, special or intermediate surveys).  

(6)

Fleet utilization is calculated by dividing voyage days by available days for the relevant period.

(7)

Represents the weighted average per-day TCE rates, of our entire fleet. TCE rate is a measure of the average daily revenue performance of a vessel on a per voyage basis. Our method of calculating TCE rate is determined by dividing voyage revenues (net of voyage expenses and amortization of fair value of above/below market acquired time charter agreements) by voyage days for the relevant time period. Voyage expenses primarily consist of port, canal and fuel costs that are unique to a particular voyage, which would otherwise be paid by the charterer under a time charter contract, as well as commissions. TCE rate is a standard shipping industry performance measure used primarily to compare period-to-period changes in a shipping company's performance despite changes in the mix of charter types (i.e., spot charters, time charters and bareboat charters) under which the vessels may be employed between the periods. We included TCE revenues, a non- GAAP measure, as it provides additional meaningful information in conjunction with voyage revenues, the most directly comparable GAAP measure, because it assists our management in making decisions regarding the deployment and use of its vessels and in evaluating their financial performance.

EBITDA and Adjusted EBITDA Reconciliation

Star Bulk considers EBITDA to represent net income before interest, income taxes, depreciation and amortization. EBITDA does not represent and should not be considered as an alternative to net income or cash flow from operations, as determined by United States generally accepted accounting principles, (“U.S. GAAP”), and our calculation of EBITDA may not be comparable to that reported by other companies. EBITDA is included herein because it is a basis upon which the Company assesses its liquidity position it is used by our lenders as a measure of our compliance with certain loan covenants and because the Company believes that it presents useful information to investors regarding the Company’s ability to service and/or incur indebtedness.

The Company excluded amortization of the fair value of above/below market acquired time charters associated with time charters attached to vessels acquired, vessel impairment loss, loss on bad debts, non-cash gain or loss related to early time charter termination, non-cash gain or loss related to sale of vessel, change in fair value of derivatives and stock -based compensation expense recognized during the period, to derive adjusted EBITDA. The Company excluded the above non-cash items to derive adjusted EBITDA because the Company believes that these non-cash items do not reflect the operational cash inflows and outflows of the Company’s fleet.

The following unaudited table reconciles net cash provided by operating activities to EBITDA and adjusted EBITDA:
