Euroseas Ltd. Announces Commencement of Rights Offering; Will Host a Conference Call on Tuesday, September 8, 2015 at 10:00 a.m. Eastern Time to Discuss the Rights Offering

Maroussi, Athens, Greece – August 31, 2015 – Euroseas Ltd. (the "Company") (NASDAQ: ESEA), an owner and operator of drybulk and container carrier vessels and provider of seaborne transportation for drybulk and containerized cargoes, announced today that it has commenced its previously announced rights offering to shareholders of the Company.

Pursuant to the rights offering, the Company will offer up to approximately 4,338,018 shares of common stock (the "Offered Shares") to holders of record of its common stock (the "Record Date Holders") as of the close of business on August 14, 2015 (the "Record Date").  The  Company intends to commence the mailing of an offering subscription package to Record Date Holders today.

The Company intends to raise gross proceeds of approximately $19.5 million through the rights offering and to use the proceeds to renew and expand its fleet by taking delivery of its drybulk vessels currently under construction and for general corporate purposes.

The Offered Shares will be sold to Record Date Holders pursuant to non-transferable subscription rights.  Basic subscription rights will be allocated in three non-transferable subscription rights for each four shares of common stock owned by Record Date Holders on the Record Date. Each subscription right represents the right to purchase one share of common stock of the Company at a subscription price of $4.50 per share and consists of a basic subscription privilege and an oversubscription privilege, which will be available if the rights offering is not fully subscribed under the basic subscription privilege.  Offered Shares not purchased under the basic subscription privilege can be purchased pursuant to the oversubscription privilege, subject to the limits set forth in the prospectus for the Rights Offering, and will be allocated to Record Date Holders choosing to exercise their oversubscription privilege.  If more requests for oversubscription shares are received than shares are available, shares not purchased under the basic subscription privilege will be allocated to Record Date Holders exercising their oversubscription pro rata to each oversubscribing holder based on the number of shares such holder purchased pursuant to the exercise of its basic subscription privilege in proportion to the total number of shares purchased by all oversubscribing holders pursuant to the exercise of their basic subscription privileges.

The offering will expire on September 17, 2015, unless extended by the Company.  Should the rights offering be extended, the Company will announce the extension as soon as practicable by issuing a press release.
