CEO Statement

Paul Wogan, Chief Executive Officer, stated: “GasLog achieved record revenues and EBITDA in the quarter as a result of high uptime across our chartered fleet and a gradual improvement in the earnings on our spot vessels.

During the quarter, we completed the sale of the GasLog Geneva to GasLog Partners and we announced the dropdown of the Solaris, the third dropdown this year. Post the quarter end, we closed the dropdown of the Solaris. These transactions demonstrate our continued ability to recycle liquidity from the Partnership to GasLog, which we can then use to grow our LNG carrier and FSRU businesses.

We continue to make good progress on the Alexandroupolis LNG Terminal in Greece, where DEPA has signed a Cooperation Agreement for its participation in the project, which is being developed by Gastrade. The Agreement also includes next steps for DEPA to participate in the share capital of Gastrade.

In recent weeks, a number of positive data points suggest that LNG shipping market fundamentals are improving. The increase in LNG supply from both the United States (“U.S.”) and Australia is creating greater shipping activity, as the additional supply is being matched by rising demand, particularly in Asia and Europe. In contrast to recent years, the “shoulder months” of September and October have seen strong LNG demand and increasing prices in Japan, South Korea and China. We expect that the re-emergence of significant gas price differentials between the U.S., Europe and Asia will stimulate more inter-basin trade and will result in longer average voyage distances, which is positive for LNG shipping.

In the short-term LNG shipping market, spot rates have been consistently higher in 2017 than in 2016 as an increasing number of fixtures have led to higher utilisation, a return of round trip economics and an increase in customers looking for multi-month charters. We expect this trend to continue and strengthen as we enter the Northern Hemisphere winter.

With five vessels currently trading in the spot market through The Cool Pool Limited (the” Cool Pool”) and with five newbuild vessels scheduled to be delivered in 2018 and 2019, GasLog has the potential to achieve growth in revenues and EBITDA as a result of organic growth and the improving market environment.”

Completion of Dropdown of the GasLog Geneva

On July 3, 2017, GasLog closed the dropdown to GasLog Partners of 100% of the ownership interest in GAS-thirteen Ltd., the entity that owns the GasLog Geneva, for an aggregate purchase price of $211.0 million, which includes $1.0 million for positive net working capital balances transferred with the vessel.

Announcement and Post-Quarter-End Closing of Dropdown of the Solaris

On September 19, 2017, GasLog entered into a share purchase agreement for the dropdown to GasLog Partners of 100% of the ownership interest in GAS-eight Ltd., the entity that owns the Solaris, for an aggregate purchase price of $185.9 million, which includes $1.0 million for positive net working capital balances transferred with the entity. The acquisition closed on October 20, 2017.

GasLog Partners’ ATM Programme

On May 16, 2017, GasLog Partners commenced an ATM Programme under which the Partnership may, from time to time, raise equity through the issuance and sale of new common units having an aggregate offering price of up to $100.0 million in accordance with the terms of an equity distribution agreement entered into on the same date. Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Credit Suisse Securities (USA) LLC and Morgan Stanley & Co. LLC have agreed to act as sales agents.

During the third quarter of 2017, GasLog Partners issued and received payment for 1,941,008 common units at a weighted average price of $22.96 per common unit for total gross proceeds of $44.6 million and net proceeds of $43.9 million, after broker commissions of $0.6 million and other expenses of $0.1 million.

Since the commencement of the ATM Programme through September 30, 2017, GasLog Partners has issued and received payment for a total of 2,351,885 common units, with cumulative gross proceeds of $53.9 million at a weighted average price of $22.91 per unit, representing a discount of 0.6% to the volume weighted average trading price of GasLog Partners’ common units on the days on which new common units were issued. Net proceeds for the same period amounted to $52.7 million.

In the period from October 1, 2017 through October 3, 2017, GasLog Partners issued and received payment for an additional 130,220 common units at a weighted average price of $23.26 per unit for gross proceeds of $3.03 million and net proceeds of $2.99 million, after broker commissions of $0.04 million. The issuance of these units fulfilled contractual commitments entered into on or before September 30, 2017.

Financing Transactions

On July 3, 2017, GasLog repaid $41.6 million of the revolving credit facility of the credit agreement of up to $1.1 billion entered into on July 19, 2016 (the “Legacy Facility Refinancing”).

Chief Operating Officer Appointment

Following Graham Westgarth’s retirement from his position as Chief Operating Officer (“COO”), GasLog and GasLog Partners announced on August 21, 2017, that Richard Sadler was appointed as COO with effect from September 20, 2017.

(1) Adjusted Profit, EBITDA, Adjusted EBITDA and Adjusted EPS are non-GAAP financial measures and should not be used in isolation or as a substitute for GasLog’s financial results presented in accordance with IFRS. For definitions and reconciliations of these measurements to the most directly comparable financial measures calculated and presented in accordance with IFRS, please refer to Exhibit II at the end of this press release.

There were 2,116 operating days for the quarter ended September 30, 2017, as compared to 1,925 operating days for the quarter ended September 30, 2016. The increase in operating days resulted mainly from the deliveries of the GasLog Geneva and the GasLog Gibraltar on September 30, 2016 and October 31, 2016, respectively.

5

Revenues were $131.2 million for the quarter ended September 30, 2017 ($120.7 million for the quarter ended September 30, 2016). The increase was mainly driven by the new deliveries in our fleet (the GasLog Geneva and the GasLog Gibraltar) and increased revenues from vessels operating in the spot market in both periods.

Vessel operating and supervision costs were $29.6 million for the quarter ended September 30, 2017 ($26.8 million for the quarter ended September 30, 2016). The increase was mainly driven by the new deliveries in our fleet (the GasLog Geneva and the GasLog Gibraltar).

Voyage expenses and commissions were $1.9 million for the quarter ended September 30, 2017 ($4.2 million for the quarter ended September 30, 2016). The decrease resulted mainly from the movement in net allocation of the Cool Pool results.

Depreciation was $34.4 million for the quarter ended September 30, 2017 ($31.4 million for the quarter ended September 30, 2016). The increase resulted from the increase in the average number of vessels in our fleet.

General and administrative expenses were $10.0 million for the quarter ended September 30, 2017 ($9.3 million for the quarter ended September 30, 2016). The increase is mainly attributable to an increase in employee costs.

Financial costs were $34.7 million for the quarter ended September 30, 2017 ($46.1 million for the quarter ended September 30, 2016). The decrease is mainly attributable to the write-off of $18.2 million of unamortized loan issuance costs associated with the six legacy facilities that were refinanced by the Legacy Facility Re-financing which occurred in the third quarter of 2016, partially offset by the increased average debt outstanding as a result of the debt drawdowns for the new vessels delivered in 2016 and the increased weighted average interest rate. An analysis of financial costs is set forth below.

(All amounts expressed in thousands of U.S. dollars)	For the three months ended
	September 30, 2016		September 30, 2017
Financial costs
Amortization and write-off of deferred loan issuance costs	$	20,889	$	2,898
Interest expense on loans and realized loss on cash flow hedges	18,731		21,100
Interest expense on senior unsecured notes and realized loss on CCS	3,034		7,526
Finance lease charge	2,785		2,731
Other financial costs	655		454
Total	$	46,094	$	34,709

Gain on swaps was $3.1 million for the quarter ended September 30, 2017 ($19.9 million loss for the quarter ended September 30, 2016). An analysis of loss/gain on swaps is set forth below. The increase in gain on swaps in the third quarter of 2017 as compared to the third quarter of 2016 is mainly attributable to the decrease of $17.2 million in recycled loss that was reclassified from equity to the statement of profit or loss relating to the cumulative loss from the period that the hedges of the interest rate swaps terminated in July 2016 were effective, an increase of $3.4 million in gain from mark-to-market valuation of our derivative financial instruments carried at fair value through profit or loss and a decrease of $2.4 million in realized loss on derivative financial instruments held for trading. The $3.2 million gain from mark-to-market valuation of our derivative financial instruments in the third quarter of 2017 derived from the fact that the London Interbank Offered Rate (“LIBOR”) yield curve, which was used to estimate the present value of the estimated future cash flows, was higher than the contracted fixed interest rates resulting in a decrease in derivative liabilities from derivative financial instruments held for trading as compared to June 30, 2017.

(All amounts expressed in thousands of U.S. dollars)	For the three months ended
	September 30, 2016		September 30, 2017
Loss/(gain) on swaps
Realized loss on derivative financial instruments held for trading	$	2,509	$	69
Unrealized loss/(gain) on derivative financial instruments held for trading	184		(3,206		)
Recycled loss of cash flow hedges reclassified to profit or loss	17,238		—
Total	$	19,931	$	(3,137	)

There was a profit of $24.2 million for the quarter ended September 30, 2017 ($16.4 million loss for the quarter ended September 30, 2016). This increase in profit is mainly attributable to the increase in gain on swaps, the decrease in financial costs and the increase in profit from operations due to the factors mentioned above.

Adjusted Profit(1) was $21.1 million for the quarter ended September 30, 2017 ($19.5 million for the quarter ended September 30, 2016) adjusted for the effects of the non-cash gain on swaps, the write-off of unamortized loan fees as well as the net foreign exchange losses.

Profit attributable to the owners of GasLog was $5.3 million ($29.0 million loss for the quarter ended September 30, 2016). The increase in profit attributable to the owners of GasLog resulted mainly from the respective movements in profit mentioned above, partially offset by the increased amount allocated to third parties as a result of GasLog Partners’ equity offerings in August 2016 and January 2017, its ATM Programme initiated in May 2017, and the associated dropdown of three vessels.

EBITDA(1) was $89.6 million for the quarter ended September 30, 2017 ($80.8 million for the quarter ended September 30, 2016).

Adjusted EBITDA(1) was $89.7 million for the quarter ended September 30, 2017 ($81.1 million for the quarter ended September 30, 2016).

Earnings per share was $0.03 for the quarter ended September 30, 2017 (a loss of $0.39 for the quarter ended September 30, 2016).

6

Adjusted Loss per share(1) was $0.00 for the quarter ended September 30, 2017 (earnings of $0.05 for the quarter ended September 30, 2016).

(1) Adjusted Profit, EBITDA, Adjusted EBITDA and Adjusted EPS are non-GAAP financial measures and should not be used in isolation or as a substitute for GasLog’s financial results presented in accordance with IFRS. For definitions and reconciliations of these measurements to the most directly comparable financial measures calculated and presented in accordance with IFRS, please refer to Exhibit II at the end of this press release.

Contracted Charter Revenues

GasLog’s contracted charter revenues are estimated to increase from $444.5 million for the fiscal year 2016 to $486.8 million for the fiscal year 2019, based on contracts in effect as of September 30, 2017, without including any extension options. As of September 30, 2017, the total future firm contracted revenue stood at $3.2 billion (1), including the twelve vessels currently owned by GasLog Partners but excluding the vessels operating in the spot market.

(1) Contracted revenue calculations assume: (a) 365 revenue days per annum, with 30 off-hire days when the ship undergoes scheduled dry-docking; (b) all LNG carriers on order are delivered on schedule; and (c) no exercise of any option to extend the terms of charters.

Liquidity and Capital Resources

As of September 30, 2017, GasLog had $358.0 million of cash and cash equivalents, of which $223.3 million was held in time deposits and the remaining balance in current accounts. In addition, as of September 30, 2017, GasLog had $22.2 million held in time deposits with an initial duration of more than three months but less than a year that have been classified as short-term investments.

As of September 30, 2017, GasLog had an aggregate of $2.6 billion of indebtedness outstanding under its credit facilities and bond agreements (net of unamortized deferred loan fees), of which $178.8 million was repayable within one year, and a $215.2 million finance lease liability related to the sale and leaseback of the Methane Julia Louise, of which $6.2 million was repayable within one year.

On July 3, 2017, GasLog repaid $41.6 million of the revolving credit facility of the Legacy Facility Refinancing. As of September 30, 2017, there was undrawn available capacity of $100.0 million under the revolving credit facility of the Legacy Facility Refinancing.

As of September 30, 2017, GasLog’s principal commitments for capital expenditures are related to the five LNG carriers on order, which have a gross aggregate contract price of approximately $1.0 billion. As of September 30, 2017, the total remaining balance of the contract prices of the aforementioned newbuildings was $901.1 million which GasLog expects to be funded with the $664.0 million undrawn capacity under the financing agreement entered into on October 16, 2015, as well as cash balances, cash from operations, cash from future dropdowns, if any, and borrowings under new and existing debt agreements.

As of September 30, 2017, GasLog’s current assets totaled $407.8 million while current liabilities totaled $281.8 million, resulting in a positive working capital position of $126.0 million.

GasLog has hedged 53.4% of its expected floating interest rate exposure on its outstanding debt (excluding the finance lease liability) as of September 30, 2017.

Future Deliveries

GasLog has three newbuildings on order at Samsung Heavy Industries Co. Ltd. (“Samsung”) and two newbuildings on order at Hyundai Heavy Industries Co. Ltd. (“Hyundai”). Our vessels presently under construction are on schedule and within budget. The expected delivery dates are as follows:

Hulls	Delivery date	Shipyard

LNG Market Update and Outlook

During the quarter and post quarter end, there has been continued momentum in the start-up of new LNG liquefaction capacity with the fourth train at Sabine Pass in the U.S. shipping its first commissioning cargoes in August 2017. Sabine Pass has now shipped approximately 200 cargoes since start up in early 2016. Post quarter end, Chevron’s Wheatstone LNG project in Australia started production with the first LNG shipment expected in the coming weeks. Dominion’s Cove Point project in the U.S. and Novatek’s Yamal LNG project in Russia are both expected to start LNG production by the end of 2017 and ramp up exports into 2018. With the addition of these two projects, over 30 million tonnes per annum (“mtpa”) of new nameplate capacity will have been added in 2017, an increase of 11% over 2016, with the majority coming online in the second half of the year.

Looking longer term, final investment decisions (“FIDs”) for new liquefaction projects continue to be limited in the current environment, although a number of projects are making further progress towards FID in the U.S. and other regions. Tellurian has acquired natural gas reserves in northern Louisiana as future feedstock for their Driftwood LNG project and has also chartered an LNG vessel to trade short term LNG cargoes. In July 2017, Magnolia LNG secured $1.5 billion of conditional funding from Stonepeak, which is expected to fund a significant portion of the project’s future equity requirement. Also during the quarter, Next Decade merged with Harmony Merger Corp. to achieve a public listing on the Nasdaq and has a current market capitalisation of around $1 billion. In Mozambique, it has been reported that PTT of Thailand has committed to offtake from the Area 1 LNG project which is expected to take FID in 2018.

Demand for LNG in 2017 to date has continued to rise sharply, particularly in Asia and Europe, with material year-on-year increases in the world’s three largest import markets, Japan, South Korea and China, where imports have increased by 5%, 21% and 44% respectively. Rising Asian LNG demand into the Northern Hemisphere winter months has caused Asian LNG prices to rise, resulting in a reopening of both the U.S. - Asia and Europe - Asia gas price arbitrages. The same trend emerged during the 2016-2017 winter period, resulting in a greater number of U.S. cargoes travelling to Asia, which increased tonne mile demand and helped to drive LNG spot shipping rates higher.

Longer term demand for LNG is also emerging. In August 2017, Petronet announced that it had renegotiated its LNG supply agreement with ExxonMobil with new terms including an increase of 1 mtpa to be supplied from ExxonMobil’s global portfolio. In September 2017, it was reported that PTT had entered into a contract to acquire 2.6 mtpa for 20 years from the Area 1 LNG project in Mozambique. Also in September 2017, Petrobangla, the state-owned oil company of Bangladesh, entered into a contract with Qatar to acquire 2.3 mtpa on average for a 15-year period. Finally, in August 2017, it was announced that Gunvor had committed to take up to 2.2 mtpa from the Fortuna project in Equatorial Guinea.

A number of offtakers from LNG projects currently under development are yet to secure all of their shipping requirements and we are seeing an increased level of tender activity for both near-term and longer-term shipping requirements. These tenders for multi-month to multi-year periods are for both newbuild vessels and on-the-water vessels, with the latter being positive in terms of absorbing the recent oversupply in the spot market.

In the shorter term LNG shipping market, tri-fuel diesel electric (“TFDE”) headline rates have continued to rise as we enter the Northern Hemisphere winter, with Clarksons currently quoting headline rates of $58,000, an increase of 93% from the 2017 low and approximately 76% higher than this time last year. Whilst the recovery in spot rates to mid-cycle levels is taking longer than anticipated, we have seen significantly more fixtures in 2017 compared to the same period in 2016, greater seasonality and consistently higher rates in 2017 than in 2016. This improvement in rates, coupled with no new vessel orders in the quarter and only eight in 2017 to date, gives us confidence in a continuing market recovery.

A number of markets that do not currently import gas are exploring LNG as an alternative to oil and coal or to replace declining domestic supply. Many countries with growing natural gas demand for power generation and other uses, such as Ivory Coast, Ghana, South Africa, Bangladesh and Myanmar, are looking at FSRUs as a quick-to-market, cost-effective solution to import LNG. Other countries with FSRUs already in place, such as Pakistan, are looking at expanding their use of FSRUs due to the successful commissioning and effective operations of the existing units. Many producers and marketers of LNG appear to be focusing their attention on FSRUs as a key enabler in creating new markets for their LNG.

EXHIBIT II

Non-GAAP Financial Measures:

EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted EPS

EBITDA is defined as earnings before depreciation, amortization, financial income and costs, gain/loss on swaps and taxes. Adjusted EBITDA is defined as EBITDA before foreign exchange gains/losses. Adjusted Profit represents earnings before write-off and accelerated amortization of unamortized loan fees/bond fees and premium, foreign exchange gains/losses and non-cash gain/loss on swaps that includes (if any) (a) unrealized gain/loss on derivative financial instruments held for trading and (b) recycled loss of cash flow hedges reclassified to profit or loss. Adjusted EPS represents earnings attributable to owners of the Group before non-cash gain/loss on swaps as defined above, foreign exchange gains/losses and write-off and accelerated amortization of unamortized loan/bond fees and premium, divided by the weighted average number of shares outstanding. EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted EPS are non-GAAP financial measures that are used as supplemental financial measures by management and external users of financial statements, such as investors, to assess our financial and operating performance. We believe that these non-GAAP financial measures assist our management and investors by increasing the comparability of our performance from period to period. We believe that including EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted EPS 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 purchase and/or to continue to hold our common shares. This is achieved by excluding the potentially disparate effects between periods of, in the case of EBITDA and Adjusted EBITDA, financial costs, gain/loss on swaps, taxes, depreciation and amortization; in the case of Adjusted EBITDA, foreign exchange gains/losses; and in the case of Adjusted Profit and Adjusted EPS, non-cash gain/loss on swaps, foreign exchange gains/losses and write-off and accelerated amortization of unamortized loan/bond fees and premium, which items are affected by various and possibly changing financing methods, financial market conditions, capital structure and historical cost basis, and which items may significantly affect results of operations between periods.

EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted EPS have limitations as analytical tools and should not be considered as alternatives to, or as substitutes for, or superior to, profit, profit from operations, earnings per share or any other measure of operating performance presented in accordance with IFRS. Some of these limitations include the fact that they do not reflect (i) our cash expenditures or future requirements for capital expenditures or contractual commitments, (ii) changes in, or cash requirements for, our working capital needs and (iii) the cash requirements necessary to service interest or principal payments on our debt. Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will have to be replaced in the future, and EBITDA and Adjusted EBITDA do not reflect any cash requirements for such replacements. EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted EPS are not adjusted for all non-cash income or expense items that are reflected in our statements of cash flows and other companies in our industry may calculate these measures differently than we do, limiting their usefulness as a comparative measure.

In evaluating Adjusted EBITDA, Adjusted Profit and Adjusted EPS, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of Adjusted EBITDA, Adjusted Profit and Adjusted EPS should not be construed as an inference that our future results will be unaffected by the excluded items. Therefore, the non-GAAP financial measures as presented below may not be comparable to similarly titled measures of other companies in the shipping or other industries.
