Exhibit 99.1

GasLog Ltd. Announces Agreement to Purchase

Three LNG Carriers from BG Group

MONACO — January 15, 2014 — GasLog Ltd. (“GasLog”) (NYSE:GLOG) today announced an agreement with Methane Services Ltd. (“MSL”), an affiliate of BG Group, to purchase three LNG carriers from MSL’s fleet and to charter those ships back to MSL for six-year initial terms. MSL also will have options to extend the term of the time charters for two of the ships for a period of either three or five years at its election. The ships to be acquired will be nominated by MSL from an agreed group of six sister ships built in 2006 and 2007. GasLog supervised the construction of all six ships and has provided technical management for the ships since delivery. The aggregate cost to GasLog for the ships is expected to be approximately $468 million.

Each LNG carrier to be acquired is modern, steam powered and has a capacity of 145,000 cubic meters. The Company estimates that upon their acquisition, these ships will represent approximately $426.3 million of incremental contracted revenue over their initial charter terms and add over $50.0 million per annum to GasLog’s EBITDA¹.

Paul Wogan, CEO of GasLog, commented that “we are very pleased that we will be able to add these LNG carriers to our fleet as it again demonstrates our ability to be a consolidator in this industry. We know these ships well, having supervised their construction and technically operated them since their delivery from Samsung Heavy Industries. We expect the transaction to be accretive to our earnings and support increased dividend capacity. This transaction also further strengthens our long-standing relationship with BG Group.”

The closing of the transaction is subject to the satisfaction of certain conditions, including the completion of definitive documentation and necessary financing. GasLog expects the transaction to close in the first or second quarter of 2014.

In connection with the transaction, GasLog has obtained commitments from Citibank, N.A. London Branch for a $325.5 million credit facility and a bridge loan facility. Although GasLog has obtained the bridge loan facility to maximize transactional certainty, it may pursue one or more alternative capital-raising transactions to fund a portion of the vessel purchase price, in which case it would not expect to borrow under the bridge loan facility.

Poten Capital Services (UK) advised GasLog on this transaction.

In a separate press release, GasLog announced that it expects to confidentially submit to the United States Securities and Exchange Commission a draft registration statement for an initial public offering of units in a master limited partnership to be formed to own certain of GasLog’s ships with multi-year charters.

¹ EBITDA, which represents earnings before interest income and expense, taxes, depreciation and amortization, is a non-GAAP financial measure. Please refer to Exhibit I for guidance on the underlying assumptions used to derive EBITDA.

EXHIBIT I

Non-GAAP Financial Measures:

EBITDA represents earnings before interest income and expense, taxes, depreciation and amortization. EBITDA, which is a non-GAAP financial measure, is used as a supplemental financial measure by management and external users of financial statements, such as investors, to assess our financial and operating performance. We believe that this non-GAAP financial measure assists our management and investors by increasing the comparability of our performance from period to period. We believe that including EBITDA assists our management and investors in (i) understanding and analyzing the results of our operating and business performance, (ii) selecting between investing in us and other investment alternatives and (iii) monitoring our ongoing financial and operational strength in assessing whether to continue to hold our common shares.

EBITDA has limitations as an analytical tool and should not be considered as an alternative to, or as a substitute for, profit, profit from operations, earnings per share or any other measure of financial performance presented in accordance with IFRS. This non-GAAP financial measure excludes some, but not all, items that affect profit, and this measure may vary among companies. This non-GAAP financial measure may not be comparable to similarly titled measures of other companies in the shipping or other industries.

Estimated EBITDA for the three LNG carriers being purchased by GasLog for the first twelve months of operation is based on the following assumptions:

• Closing of the acquisition in the first or second quarter of 2014 and timely receipt of charter hire specified in the charter contracts;

• Utilization of 363 days per year and no drydocking;

• Vessel operating and supervision costs and charter commissions per current internal estimates; and

• General and administrative expenses per current internal estimates.

GasLog considers the above assumptions to be reasonable as of the date of this release, but if these assumptions prove to be incorrect, actual EBITDA for the vessels could differ materially from the Company’s estimates.
