BG GROUP PLC
2007 FIRST QUARTER RESULTS
- --------------------------------------------------------------------------------


BG Group's Chief Executive, Frank Chapman said:

"BG has delivered a good operating performance against a background of softer
commodity prices and a weaker US dollar. In addition, the ramping up of
production from Buzzard, a new LNG supply agreement from Nigeria and the award
of an initial FEED contract for the Karachaganak Phase III expansion represent
solid progress against our long-term growth programme."

                              RESULTS PRESENTATION


The presentation of BG Group's results under IFRS separately identifies the
effect of:

  - The re-measurement of certain financial instruments.
  - Profits and losses on the disposal and impairment of non-current assets
    and businesses.

These items are excluded from Business Performance in order to provide readers
with a clear and consistent presentation of the underlying operating performance
of the Group's ongoing businesses.

Under IFRS the results of joint ventures and associates are presented net of
finance costs and tax (see page 12). Given the relevance of these businesses
within BG Group, the results of joint ventures and associates are presented both
before interest and tax, and after tax. The pre-interest and tax result is
included in Business Performance discussed on pages 4 to 9. The table below sets
out the amounts related to joint ventures and associates, re-measurements under
IAS 39 and profits on disposal and impairment of non-current assets and
businesses.

i) Re-measurements excluded from Business Performance

   The IAS 39 re-measurements reflect movements in external market prices and
   exchange rates. Financial instruments include certain long-term UK gas
   contracts which are classified as derivatives under IAS 39 due to the nature
   of the contract terms and are therefore required to be marked-to-market. This
   treatment has no impact on the ongoing cashflows of the business and these
   unrealised mark-to-market movements are best presented separately from
   underlying business performance. For an explanation of Non-GAAP measures see
   page 10.



                                BUSINESS REVIEW


The results discussed in this Business Review (pages 4 to 9) relate to BG
Group's performance excluding disposals, re-measurements and impairments. For
the impact and a description of these items, see the consolidated income
statement (page 12) and Note 2 of the accounts (page 17). Results at constant
US$/UKGBP exchange rates and upstream prices are also quoted. See Presentation
of Non-GAAP measures (page 10) for an explanation of these metrics.

Revenue and other operating income was broadly in line with the prior year.
Increased volumes in all segments were offset by lower prices in the E&P and LNG
segments and the weaker US$/UKGBP exchange rate.

Total operating profit of GBP823 million reflected a 4% increase in E&P
production volumes, offset by lower commodity prices and a weaker US$/UKGBP
exchange rate. At constant US$/UKGBP exchange rates and upstream prices,
underlying total operating profit would have increased by 3%.

The increase in the Group's effective tax rate (including BG Group's share of
joint ventures and associates) from 40% to 43.7% reflects the increase in the
North Sea tax rate which became effective from the second quarter 2006.

Cash conversion remained strong with cash generated by operations of GBP1 086
million.


Capital investment in the quarter of GBP869 million included power plant
acquisitions of GBP431 million in the USA and Italy, E&P acquisitions of GBP67
million in the UK, and continuing investment in North America and the Caribbean
(GBP110 million), Europe and Central Asia (GBP113 million), Mediterranean Basin
and Africa (GBP93 million), Asia Pacific (GBP36 million) and South America
(GBP19 million).

As at 31 March 2007, the Group had returned GBP105 million to shareholders as
part of the share repurchase programme announced on 8 February 2007. As at 31
March 2007, net borrowings were GBP27 million.

Additional operating and financial data are given on page 23.


E&P total operating profit of GBP626 million reflected a 4% increase in volumes,
offset by lower commodity prices and a weaker US$/UKGBP exchange rate. At
constant US$/UKGBP exchange rates and upstream prices, total operating profit
would have increased by 6%.

Production volumes increased by 4% principally due to Atlantic/Cromarty and the
start-up of the Buzzard field in the UK.

Unit operating expenditure was up 33 pence to GBP2.51 per boe reflecting the
start-up of new fields in the UK and maintenance activity.

The exploration charge of GBP56 million is GBP12 million higher than 2006
reflecting the increased exploration activities across the Group.

The Group's average realised international gas price was 16.3 pence (2006 18.4
pence) per produced therm reflecting lower Henry Hub prices and a weaker
US$/UKGBP exchange rate. In the UK, the average realised price per produced
therm was 37.0 pence (2006 38.8 pence).

Capital investment of GBP359 million included expenditure in Egypt (GBP28
million), India (GBP31 million), Trinidad and Tobago (GBP21 million), Tunisia
(GBP63 million) and the UK (GBP141 million).

Additional operating and financial data are given on page 23.


LNG total operating profit fell by GBP17 million to GBP121 million as higher
volumes were more than offset by the lower Henry Hub price and the weaker
US$/UKGBP exchange rate.

In shipping and marketing, total operating profit of GBP115 million was down 9%,
reflecting the weaker US$ and lower Henry Hub price. At constant US$/UKGBP
exchange rates, shipping and marketing underlying total operating profit would
have increased by 2%.

Managed volumes were up 25% due to increased long-term contracted supply and
higher spot cargo availability.

BG Group's share of operating profit from liquefaction activities decreased by
GBP5 million to GBP25 million, principally due to lower Henry Hub prices.

Capital investment includes GBP43 million relating to LNG vessels, GBP6 million
relating to regasification development projects and GBP9 million in Atlantic
LNG.

T&D total operating profit for the quarter was GBP50 million.

At Comgas, in Brazil, total operating profit of GBP40 million was down GBP10
million as the 7% increase in volumes was offset by the adverse effect of the
Brazilian Real (BRL) exchange rate, movements in the regulatory current account
and higher costs. Operating profit in the quarter includes GBP2 million (2006
GBP5 million) to be passed back to customers in future periods. At the end of
the quarter, the total to be passed back to customers in future periods is GBP8
million.

Profits derived from Interconnector capacity were GBP5 million lower reflecting
lower differentials between UK and European gas prices.

Capital investment mainly represents the development of the Comgas pipeline
network.

The increase in revenue is primarily due to the pass through of gas costs. Total
operating profit of GBP38 million in the quarter was broadly in line with 2006.
This includes a one-off contribution from the settlement of a contractual
dispute at Premier Power, and lower profits at Seabank where one-off insurance
proceeds arose in 2006.

Capital investment relates primarily to the acquisitions of the Lake Road power
plant in the USA and the remaining equity (66.3%) of Serene S.p.A in Italy.


                       First quarter business highlights


The acquisition of the Lake Road power plant, located in Connecticut, USA
completed on 13 March and the acquisition of the remaining equity in the Serene
power plants, Italy completed on 14 February.

On 2 April, BG Group announced that it had signed a Sale and Purchase Agreement
to acquire the Masspower power plant, a 262 MW gas- and oil-fired combined cycle
facility located in Indian Orchard, Massachusetts, USA for US$150 million. The
purchase completed on 1 May 2007.


                      Presentation of Non-GAAP measures

  Business Performance

  'Business Performance' excludes disposals, certain re-measurements and
  impairments (see below) as exclusion of these items provides a clear and
  consistent presentation of the underlying operating performance of the Group's
  ongoing business.

  BG Group uses commodity instruments to manage price exposures associated with
  its marketing and optimisation activity in the UK and US. This activity
  enables the Group to take advantage of commodity price movements. It is
  considered more appropriate to include both unrealised and realised gains and
  losses arising from the mark-to-market of derivatives associated with this
  activity in 'Business Performance'.

  Disposals, certain re-measurements and impairments

  BG Group's commercial arrangements for marketing gas include the use of
  long-term gas sales contracts. Whilst the activity surrounding these contracts
  involves the physical delivery of gas, certain UK gas sales contracts are
  classified as derivatives under the rules of IAS 39 and are required to be
  measured at fair value at the balance sheet date. Unrealised gains and losses
  on these contracts reflect the comparison between current market gas prices
  and the actual prices to be realised under the gas sales contract.

  BG Group also uses commodity instruments to manage certain price exposures in
  respect of optimising the timing of its gas sales associated with contracted
  UK storage and pipeline capacity. These instruments are also required to be
  measured at fair value at the balance sheet date under IAS 39. However, IAS 39
  does not allow the matching of these fair values to the economically hedged
  value of the related gas in storage (taking account of gas prices based on the
  forward curve or expected delivery destination and the associated storage and
  capacity costs).

  BG Group also uses financial instruments, including derivatives, to manage
  foreign exchange and interest rate exposure. These instruments are required to
  be recognised at fair value or amortised cost on the balance sheet in
  accordance with IAS 39. Most of these instruments have been designated either
  as hedges of foreign exchange movements associated with the Group's net
  investments in foreign operations, or as hedges of interest rate risk. Where
  these instruments cannot be designated as hedges under IAS 39, unrealised
  movements in fair value are recorded in the income statement.

  Unrealised gains and losses in respect of long-term gas sales contracts and
  derivatives associated with gas in UK storage and pipeline facilities and
  interest rate and foreign exchange exposure in respect of financial
  instruments which cannot be designated as hedges under IAS 39 are disclosed
  separately as 'disposals, re-measurements and impairments'. Realised gains and
  losses relating to these instruments are included in Business Performance.
  This presentation best reflects the underlying performance of the business
  since it distinguishes between the temporary timing differences associated
  with re-measurements under IAS 39 rules and actual realised gains and losses.

  BG Group has also separately identified profits and losses associated with the
  disposal of non-current assets, closures and impairments, as they are items
  which require separate disclosure in order to provide a clearer understanding
  of the results for the period.

  For a reconciliation between the overall results and Business Performance and
  details of disposals, re-measurements and impairments, see the consolidated
  income statement, page 12 and note 2 to the accounts, page 17.

  Joint ventures and associates

  Under IFRS the results from jointly controlled entities (joint ventures) and
  associates, accounted for under the equity method, are required to be
  presented net of finance costs and tax on the face of the income statement.
  Given the relevance of these businesses within BG Group, the results of joint
  ventures and associates are presented before interest and tax, and after tax.
  This approach provides additional information on the source of BG Group's
  operating profits. For a reconciliation between operating profit and earnings
  including and excluding the results of joint ventures and associates, see Note
  3 to the accounts, page 18.

  Exchange rates and prices

  BG Group also discloses certain information, as indicated, at constant
  US$/UKGBP exchange rates and upstream prices. The presentation of results in
  this manner is intended to provide additional information to explain further
  the underlying trends in the business.

  Net borrowings/funds

  BG Group provides a reconciliation of net borrowings/funds and an analysis of
  the amounts included within net borrowings/funds as this is an important
  liquidity measure for the Group.

Notes


1. Basis of preparation

These primary statements are the unaudited interim consolidated financial
statements of BG Group plc for the quarter ended 31 March 2007. The financial
information does not comprise statutory accounts within the meaning of Section
240 of the Companies Act 1985, and should be read in conjunction with the Annual
Report and Accounts for the year ended 31 December 2006, as they provide an
update of previously reported information.

The preparation of the interim financial statements requires management to make
estimates and assumptions that affect the reported amount of revenues, expenses,
assets and liabilities at the date of the interim financial statements. If in
the future such estimates and assumptions, which are based on management's best
judgment at the date of the interim financial statements, deviate from the
actual circumstances, the original estimates and assumptions will be modified as
appropriate in the year in which the circumstances change.

First quarter: Revenue and other operating income

Re-measurements included within revenue and other operating income amount to a
charge of GBP33 million for the quarter (2006 GBP24 million credit), of which a
GBP3 million charge (2006 GBP19 million credit) represents non-cash
mark-to-market movements on certain long-term UK gas contracts. Whilst the
activity surrounding these contracts involves the physical delivery of gas, the
contracts fall within the scope of IAS 39 and meet the definition of a
derivative instrument.


Net finance costs

Re-measurements presented in net finance costs relate primarily to certain
derivatives used to hedge foreign exchange and interest rate risk which have not
been designated as hedges under IAS 39, partly offset by foreign exchange
movements on certain borrowings in a subsidiary.


2007 first quarter: Disposal of non-current assets

During the first quarter, BG Group disposed of its Mauritanian interests. This
resulted in a loss on disposal of GBP1 million. No tax arose on the disposal.

Supplementary information: Operating and financial data (continued)

BG Group's exposure to the oil price varies according to a number of factors
including the mix of production and sales. Management estimates that, other
factors being constant, a $1.00 rise (or fall) in the Brent price would increase
(or decrease) operating profit in 2007 by approximately GBP40 million to
GBP50 million.

BG Group's exposure to the US$/UKGBP exchange rate varies according to a number
of factors including commodity prices and the timing of US Dollar revenues and
costs including capital expenditure. Management estimates that in 2007, other
factors being constant, a 10 cent strengthening (or weakening) in the US Dollar
would increase (or decrease) operating profit by approximately GBP140 million to
GBP160 million.
