OPERATING AND FINANCIAL REVIEW

The Company generates revenue primarily from ferry operations, chartering out its owned, chartered-in and leased Roll-on/Roll-off vessels, tankers and drilling rigs, managing tankers, sales of vessels and real estate rents. The period from June through September is the peak travel season for passengers of the ferry operations. Chartering activities are not significantly affected by seasonal fluctuations, but variations over the year may occur as a consequence of, among other things, vessel utilization rates, dry-docking and charter rates. Any sale or acquisition of vessels, drilling rigs and real estate also may have an impact on the results of each period.

Highlights of the first three months of 2011

During autumn of 2010, Stena Line entered into an agreement to acquire the Danish travel agency DTF (Dansk Total Ferie), a market leading travel agency for vacations by car in Denmark. The travel agency was acquired as of January 1, 2011.

Stena Line has entered into a slot charter agreement with DFDS on the Esbjerg-Harwich and Esbjerg-Immingham routes. This means that Stena Line as from January 2011 also can offer a freight service between Denmark and UK.

Stena Line has as of December1, 2010 from DFDS acquired two routes on the Irish Sea: Liverpool–Belfast and Heysham–Belfast. Since the acquisition is subject to a formal approval from the British competition authority, these routes are being held separated from our other business until approval is given.

Stena Transporter, a new built Ropax vessel, was delivered in January from Samsung Heavy Industries in Korea. Stena Transporter is the first vessel of two ordered from Samsung. The vessels are on operation on the route Hoek van Holland and Killingholme.

In February the vessel Highlanders (previously called Stena Traveller) was delivered to the Canadian company Marine Atlantic Inc. Highlanders has been rebuilt in the same way as her sister vessel Blue Puttees (previously called Stena Trader), meaning that the vessel has been shortened by 12 meters and has had its passenger capacity increased. Blue Puttees and Highlanders will operate between North Sydney, Nova Scotia and Port aux Basque, Newfoundland on a charter for a minimum of five years.

Stena Bulk A/S and Dannebrog Rederi A/S signed a joint venture agreement on March 25, 2011 regarding the ownership in Stena Weco A/S. The new joint venture will charter and operate a fleet of 30-40 Handy and Medium Range product tankers.

As of March 31, 2011 Stena Adactum owns 99% of the shares in Ballingslöv.

In March 2011, the drilling rig Stena Tay was sold subject to certain conditions being met, with expected delivery in the fourth quarter 2011.

Stena Property sold one property for SEK 85 million during the first quarter of 2011.

SUBSEQUENT EVENTS

In April, 2011 Stena RoRo acquired the vessel, Dublin Seaways, from DFDS for EUR 24 million.

In May 2011 three LNG (Liquified Natural Gas) vessels were acquired for a total purchase price of USD 667 million. The first vessel, Bluesky, was built in 2006 and is on a charter to Gazprom for 22 months. The second and third vessel, Clearsky and Crystalsky, are newly built and will be delivered in May 2011.

In May, 2011 three vessels, Stena Leader, Stena Pioneer and Stena Seafarer have been sold for an aggregate price of USD 6.5 million.

The Competition Commission in UK has provisionally cleared Stena AB’s completed acquisition of two Irish Sea ferry services from DFDS A/S. Final report is due in July 2011.

Stena AB and Consolidated Subsidiaries

In May 2011, the English Court of Appeals affirmed a High Court ruling that contributions to repair the deficit in the Merchant Navy Ratings Pension Fund can be required from any company that has participated in the Fund, including companies that no longer employ any members. In the late 1990s, the Fund had been found to have a deficit. Stena Line has been providing funds to reduce the deficit. As a result of the Court of Appeals decision, the non-contributing employers also will be required to contribute funds to reduce the deficit and the Company's contributions will be significantly reduced.

Currency effects

Our revenues and expenses, reported in Swedish kronor, are significantly affected by fluctuations in currency exchange rates, primarily relative to the U.S. dollar, the British pound and the euro. We seek to mitigate the impact of potential adverse foreign currency exchange fluctuations by matching, to the extent possible, revenues and expenses in the same currency. In addition, we enter into certain derivative financial instruments. In the period ended March 31, 2011, approximately 39% of our total revenues were generated in U.S. dollars and approximately 27% were generated in SEK.

In the period ended March 31, 2011, approximately 33% of our total expenses were incurred in U.S. dollars and approximately 28% were incurred in SEK. The reported gross revenues and expenses were influenced by changes in currency rates. The exchange rates as used for consolidation purposes are as follows:

Average rates:	Jan-Mar	Jan-Mar	Change
	2010	2011

US $	7.1918	6.4830	(10)%
British pound	11.2133	10.3899	(7)%
Euro	9.9440	8.8685	(11)%

Closing rates:	As of	As of	Change
	Dec 31, 2010	Mar 31, 2011

THREE MONTHS ENDED MARCH 31, 2011, COMPARED TO THREE MONTHS ENDED

MARCH 31, 2010

Revenues

Total revenues increased SEK 292 million, or 5%, in the three months ended March 31, 2011to SEK 6,031 million from SEK 5,739 million in the three months ended March 31, 2010, as a result of increased revenues in all segments except for the property and new businesses operations, offset by the weakening of the U.S. dollar, the Euro and the GBP against the SEK.

Ferry operations. Ferry revenues are primarily generated from ticket sales, freight haulage and on board sales. Revenues from ferry operations increased SEK 61 million, or 4%, in the three months ended March 31, 2011, to SEK 1,712 million from SEK 1,651 million in the three months ended March 31, 2010, mainly due to increased travel revenues after the consolidation of the Danish travel agency DTF as from January 1, 2011, offset by lower freight haulage revenues and onboard sales as a consequence from lower freight and passenger volumes. Revenues also decreased as an effect of the weakening of the Euro and the GBP against the SEK.

Drilling. Drilling revenues consist of charter hires for our drilling rigs. Revenues from drilling operations increased SEK 60 million, or 3%, in the three months ended March 31, 2011, to SEK 1,898 million from SEK 1,838 million in the three months ended March 31, 2010, mainly reflecting a planned off-hire period for Stena Don, which undertook a five-year special periodic survey in the first quarter of 2010, offset by the weakening of the U.S. dollar against the SEK.

Shipping. Shipping revenues primarily represent charter hires for our owned and chartered in vessels and management fees for vessels managed by us. Revenues from shipping operations increased SEK 215 million, or 34%, in the three months ended March 31, 2011, to SEK 842 million from SEK 627 million in the three months ended March 31, 2010.

Revenues from crude oil tankers increased SEK 138 million, or 29%, in the three months ended March 31, 2011, to SEK 611 million from SEK 473 million in the three months ended March 31, 2010, mainly due to higher operated tonnage, offset by the weakening of the U.S. dollar against the SEK. In the three months ended March 31, 2011, the Company operated an average of 32 tankers (chartered in or owned), compared to an average of 25 tankers in the three months ended March 31, 2010.
