Strategic Report
Year ended 31 December 2024
The Directors present their strategic report of Kellogg Brown & Root (U.K.) Limited (“the Company”) for
the year ended 31 December 2024.
Principal activities and business review
Principal activity
The Company's principal activity is the employment of staff on UK payrolls on behalf of certain KBR, Inc.
group companies ("the Group").
Business review
The payroll costs for the year were £150,557,000 (2023: £129,939,000). All payroll costs were recharged
to group companies at cost.
At year end the Company's defined benefit pension scheme moved from a liability of £7,271,000 in 2023 to
an asset of £61,737,000 due to changes in market conditions and assumptions made by the Company's
directors based on the actuarial valuation report at 31 December 2024. The main change in assumptions
which has contributed to the move from asset to liability is an increase in the discount rate used to calculate
the present value of future pension liabilities. The principal actuarial assumptions used can be seen in note
15 of the accounts.
Future developments
The Company will continue to provide payroll administrative services for companies in the Kellogg Brown
& Root Holdings Limited Group and is thus dependent on staffing requirements of the various projects
being run through the Group.
Results
The loss for the year, after taxation, amounted to £19,401,000 (2023: £35,699,000). The net assets at the
end of the year totalled £72,036,000 (2023: net liabilities - £515,228,000).
Financial risk management objectives and policies
Principal risks and uncertainties
The management of the business and the execution of the Company's strategy are subject to a number of
risks. The key business risks and uncertainties affecting the Company are considered to relate to the
following:
Defined benefit pension scheme liabilities. The pension scheme’s funding position and investment
performance is analysed regularly. Funding valuations are negotiated and de-risking opportunities are
reviewed.
Recoverability of intercompany receivables. Where amounts are due from group companies with net
liabilities, parental guarantees and letters of support are obtained to ensure that they will be able to
meet their obligations as they fall due.
Solvency of KBR group. The Company is dependent on financial support and funding from other
KBR group companies.

Strategic Report (continued)
Year ended 31 December 2024
Principal risks and uncertainties (continued)
Cash flow risk, pricing risk and credit and liquidity risk are managed on a Group level and are disclosed in
the Annual Report of the Group.
Key Performance Indicators ("KPIs")

including the likely consequences of their decisions in the longer term, and how they have taken wider
stakeholders' needs into account.
During the year ended 31 December 2024, the board reviewed its stakeholder mapping to assess whether
the identification of key stakeholders remains appropriate. It was concluded that the key stakeholders
remain the Company's ultimate parent company KBR, Inc., its subsidiaries, employees and Kellogg Brown
& Root (U.K.) Limited's Pension Scheme.
The Company is also aware of its impact on the local communities where it operates, and its wider social
and environmental responsibilities.
In order to place stakeholders' considerations at the heart of the board's decision-making process, the
directors receive regular feedback and insights on the Company's key stakeholders during their board
meetings, town halls with employees, meetings with employees' representatives, clients and pension plan
trustees. The directors recognise the importance of proactive engagement with the Company's stakeholders
in order to understand their perspectives first-hand and to maintain positive and effective relationships.
During the year, the directors discussed service delivery and other strategic matters with senior members of
the KBR, Inc. companies during formal meetings, informal correspondence and attendance at strategic
boards.
Issues related to the Company's personnel secondments to various KBR projects are addressed at regular
internal project reviews attended by the directors. By way of example, the following issues are escalated:
safety, compliance, client feedback (positive and negative), performance, potential financial impacts and all
matters about which there is doubt.
The Company's ultimate parent's board regularly receives information regarding the Company's
performance. The Company remains aligned with the strategic and business development objectives of
KBR, Inc..

Directors' Report (continued)
Year ended 31 December 2024
Going concern
The directors of the company have prepared the financial statements on a going concern basis which they
consider appropriate for the following reasons.
At the balance sheet, the company was in a net current asset position of £18,810,000 (2023: net current 
liability  - £507,957,000) and a net asset position of £72,036,000 (2023: net liability - £515,228,000),
providing employment services on behalf of certain KBR, Inc. group companies.
The defined benefit pension plan of the Company is jointly guaranteed by Kellogg Brown & Root Holdings
Limited (Principal Guarantor), Kellogg Brown & Root Holdings (U.K.) Limited (First Additional
Guarantor) and Kellogg Brown & Root Limited (Second Additional Guarantor).
Consequently, the directors are confident that the Company will have sufficient funds to continue to meet
its liabilities as they fall due for at least 12 months from the date of approval of the financial statements and
therefore have prepared the financial statements on a going concern basis.

Independent Auditor’s Report to the Member of Kellogg Brown & Root (U.K.)
Limited
Opinion
We have audited the financial statements of Kellogg Brown & Root (U.K.) Limited (the “Company”), which
comprise the Income Statement,  Statement of Comprehensive Income, Statement of Financial Position,
Statement of Changes in Equity for the year ended 31 December 2024 and the related notes to the financial
statements, including a summary of significant accounting policies.
The financial reporting framework that has been applied in the preparation of the financial statements is
applicable law and FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of
Ireland” (United Kingdom Generally Accepted Accounting Practice).
In our opinion, Kellogg Brown & Root (U.K.) Limited’s financial statements:
give a true and fair view in accordance with United Kingdom Generally Accepted Accounting Practice
of the assets, liabilities and financial position of the company as at 31 December 2024 and of its
financial performance for the year then ended;
have been properly prepared in accordance with the requirements of the Companies Act 2006.
Basis for opinion
We conducted our audit in accordance with International Standards on Auditing (UK) (‘ISAs (UK)’) and
applicable law. Our responsibilities under those standards are further described in the ‘Responsibilities of the
auditor for the audit of the financial statements’ section of our report. We are independent of the company in
accordance with the ethical requirements that are relevant to our audit of the financial statements in the United
Kingdom, including the FRC’s Ethical Standard and the ethical pronouncements established by Chartered
Accountants Ireland, applied as determined to be appropriate in the circumstances for the entity. We have
fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit
evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.
Conclusions relating to going concern
In auditing the financial statements, we have concluded that the directors’ use of going concern basis of
accounting in the preparation of the financial statements is appropriate.
Based on the work we have performed, we have not identified any material uncertainties relating to events or
conditions that, individually or collectively, may cast significant doubt on the Company’s ability to continue as a
going concern for a period of at least twelve months from the date when the financial statements are authorised
for issue.
Our responsibilities and the responsibilities of the directors with respect to going concern are described in the
relevant sections of this report.

Other information
Other information comprises information included in the annual report, other than the financial statements and
our auditor’s report thereon, including the Directors’ Report and the Strategic Report. The directors are
responsible for the other information. Our opinion on the financial statements does not cover the other
information and, except to the extent otherwise explicitly stated in our report, we do not express any form of
assurance conclusion thereon.
In connection with our audit of the financial statements, our responsibility is to read the other information and, in
doing so, consider whether the other information is materially inconsistent with the financial statements or our
knowledge obtained in the audit, or otherwise appears to be materially misstated. If we identify such material
inconsistencies in the financial statements, we are required to determine whether there is a material misstatement
in the financial statements or a material misstatement of the other information. If, based on the work we have
performed, we conclude that there is a material misstatement of this other information, we are required to report
that fact.
We have nothing to report in this regard.
Opinions on other matters prescribed by the Companies Act 2006
In our opinion, based on the work undertaken in the course of the audit:
the information given in the Strategic Report and the Directors’ Report for the financial year for which
the financial statements are prepared is consistent with the financial statements; and
the Strategic Report and the Directors’ Report have been prepared in accordance with applicable legal
requirements.
Matters on which we are required to report by exception
In the light of the knowledge and understanding of the company and its environment obtained in the course of the
audit, we have not identified any material misstatements in the Strategic Report and the Directors’ Report. We
have nothing to report in respect of the following matters where the Companies Act 2006 requires us to report to
you if, in our opinion:
adequate accounting records have not been kept, or returns adequate for our audit have not been received
from branches not visited by us; or
the financial statements and the part of the Directors’ remuneration report to be audited are not in
agreement with the accounting records and returns; or
certain disclosures of directors’ remuneration specified by law are not made; or
we have not received all the information and explanations we require for our audit.

Independent Auditor’s Report to the Member of Kellogg Brown & Root (U.K.)
Limited (continued)
Responsibilities of management and those charged with governance for the financial
statements 
As explained more fully in the Directors' responsibilities statement, management is responsible for the
preparation of the financial statements which give a true and fair view in accordance with United Kingdom
Generally Accepted Accounting Practice, including FRS 102, and for such internal control as directors determine
necessary to enable the preparation of financial statements are free from material misstatement, whether due to
fraud or error.
In preparing the financial statements, management is responsible for assessing the Company’s ability to continue
as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis
of accounting unless management either intends to liquidate the Company or to cease operations, or has no
realistic alternative but to do so.
Those charged with governance are responsible for overseeing the Company’s financial reporting process.
Responsibilities of the auditor for the audit of the financial statements
The objectives of an auditor are to obtain reasonable assurance about whether the financial statements as a whole
are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes
their opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in
accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise
from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be
expected to influence the economic decisions of users taken on the basis of these financial statements.
A further description of an auditor’s responsibilities for the audit of the financial statements is located on the
Financial Reporting Council’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of
our auditor’s report.
Explanation as to what extent the audit was considered capable of detecting irregularities,
including fraud
Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures
in line with our responsibilities, to detect material misstatements in respect of irregularities, including fraud.
Owing to the inherent limitations of an audit, there is an unavoidable risk that material misstatement in the
financial statements may not be detected, even though the audit is properly planned and performed in accordance
with the ISAs (UK).  The extent to which our procedures are capable of detecting irregularities, including fraud is
detailed below.

Independent Auditor’s Report to the Member of Kellogg Brown & Root (U.K.)
Limited (continued)
Responsibilities of the auditor for the audit of the financial statements (continued)
Explanation as to what extent the audit was considered capable of detecting irregularities,
including fraud (continued)
Based on our understanding of the company and industry, we identified that the principal risks of non-compliance
with laws and regulations related to compliance with Data Privacy law, Employment Law, Environmental
Regulations, and Health & Safety, and we considered the extent to which non-compliance might have a material
effect on the financial statements. We also considered those laws and regulations that have a direct impact on the
preparation of the financial statements such as the Companies Act 2006 and local tax legislation. We evaluated
management’s incentives and opportunities for fraudulent manipulation of the financial statements (including the
risk of override of controls), and determined that the principal risks were related to posting inappropriate journal
entries to manipulate financial performance and management bias through judgements and assumptions in
significant accounting estimates, in particular in relation to significant one-off or unusual transactions. We apply
professional scepticism through the audit to consider potential deliberate omission or concealment of significant
transactions, or incomplete/inaccurate disclosures in the financial statement. 
In response to these principal risks, our audit procedures included but were not limited to:
enquiries board on the policies and procedures in place regarding compliance with laws and regulations,
including consideration of known or suspected instances of non-compliance and whether they have
knowledge of any actual, suspected or alleged fraud;
review of minutes of board meetings during the year to corroborate inquiries made;
gaining an understanding of the internal controls established to mitigate risk related to fraud;
discussion amongst the engagement team in relation to the identified laws and regulations and regarding
the risk of fraud, and remaining alert to any indications of non-compliance or opportunities for
fraudulent manipulation of financial statements throughout the audit;
identifying and testing journal entries to address the risk of inappropriate journals and management
override of controls;
designing audit procedures to incorporate unpredictability around the nature, timing or extent of our
testing;
challenging assumptions and judgements made by management in their significant accounting estimates;
and
review of the financial statement disclosures to underlying supporting documentation and inquiries of
management.
The primary responsibility for the prevention and detection of irregularities including fraud rests with those
charged with governance and management. As with any audit, there remains a risk of non-detection or
irregularities, as these may involve collusion, forgery, intentional omissions, misrepresentations or override of
internal controls.

Kellogg Brown & Root (U.K.) Limited
Notes to the Financial Statements
Year ended 31 December 2024
1.General information
The Company is a private company limited by shares and is incorporated and domiciled in the United
Kingdom, and registered in England. The address of the registered office is Hill Park Court, Springfield
Drive, Leatherhead, Surrey, KT22 7NL.
2.Statement of compliance
These financial statements have been prepared in accordance with applicable United Kingdom Accounting
Standards, including Financial Reporting Standard 102, ‘The Financial Reporting Standard applicable in
the United Kingdom and the Republic of Ireland’ (‘FRS 102’) and the Companies Act 2006. 
3.Accounting policies
3 (a).Basis of preparation
The financial statements have been prepared on the historical cost basis, as modified by the recognition of
certain financial assets and liabilities measured at fair value.
The financial statements are prepared in sterling, which is the functional currency of the entity.
The entity satisfies the criteria of being a qualifying entity as defined in FRS 102.
The entity's financial statements are consolidated into the financial statements of KBR, Inc. (incorporated
in the state of Delaware, U.S.A.) which can be obtained from the Public Relations Department, Hill Park
Court, Springfield Drive, Leatherhead, Surrey, KT22 7NL. KBR, Inc.’s financial statements are also
available on its website (www.kbr.com). As such, advantage has been taken of the following disclosure
exemptions available under Section 1 of FRS 102 paragraphs:
1.12 (b) No cash flow statement has been presented for the company.
1.12 (e) No disclosure has been given for the aggregate remuneration of key management personnel.
The entity's financial statements are also consolidated into the financial statements of Kellogg Brown &
Root Holdings Limited  (incorporated in England & Wales) which can be obtained from the Public
Relations Department, Hill Park Court, Springfield Drive, Leatherhead, Surrey, KT22 7NL. As such,
advantage has been taken of the following disclosure exemptions available under Section 1 of FRS 102
paragraphs:
1.12(c) Disclosures in respect of financial instruments have not been presented.
- 17 -
Kellogg Brown & Root (U.K.) Limited
Notes to the Financial Statements (continued)
Year ended 31 December 2024
3 (b).Going Concern
The directors of the company have prepared the financial statements on a going concern basis which they
consider appropriate for the following reasons.
At the balance sheet, the company was in a net current asset position of £18,810,000 (2023: net current 
liability  - £507,957,000) and a net asset position of £72,036,000 (2023: net liability - £515,228,000),
providing employment services on behalf of certain KBR, Inc. group companies.
The defined benefit pension plan of the Company is jointly guaranteed by Kellogg Brown & Root Holdings
Limited (Principal Guarantor), Kellogg Brown & Root Holdings (U.K.) Limited (First Additional
Guarantor) and Kellogg Brown & Root Limited (Second Additional Guarantor).
Consequently, the directors are confident that the Company will have sufficient funds to continue to meet
its liabilities as they fall due for at least 12 months from the date of approval of the financial statements and
therefore have prepared the financial statements on a going concern basis.
3 (c).Revenue recognition
The turnover shown in the income statement represents payroll costs recharged to group companies during
the year, exclusive of Value Added Tax.
3 (d).Interest income and expenses
Interest receivable and payable on borrowings is calculated using the effective interest method and is
recognised as income or expense as it accrues.
3 (e).Income tax
The taxation expense represents the aggregate amount of current and deferred tax recognised in the
reporting period. Tax is recognised in profit or loss, except to the extent that it relates to items recognised
in other comprehensive income or directly in equity. In this case, tax is recognised in other comprehensive
income or directly in equity, respectively.
Current tax is recognised on taxable profit for the current and past periods. Current tax is measured at the
amounts of tax expected to pay or recover using the tax rates and laws that have been enacted or
substantively enacted at the reporting date.
Any taxable losses made by Group companies are surrendered to other Group companies as Group Relief
for payment. All Group Relief surrenders and claims are managed by Kellogg Brown & Root Limited as
the representative entity of the Group for corporation tax. Companies claiming and surrendering Group
Relief will therefore recognise a payable or receivable balance from Kellogg Brown & Root Limited.
Deferred tax is recognised in respect of all timing differences at the reporting date.  Unrelieved tax losses
and other deferred tax assets are recognised to the extent that it is probable that they will be recovered
against the reversal of deferred tax liabilities or other future taxable profits. Deferred tax is measured using
the tax rates and laws that have been enacted or substantively enacted by the reporting date that are
expected to apply to the reversal of the timing difference.

Kellogg Brown & Root (U.K.) Limited
Notes to the Financial Statements (continued)
Year ended 31 December 2024
3.Accounting policies (continued)
3 (f).Foreign currencies
Foreign currency transactions are initially recorded in the functional currency, by applying the spot
exchange rate as at the date of the transaction. Monetary assets and liabilities denominated in foreign
currencies are translated at the exchange rate ruling at the reporting date, with any gains or losses being
taken to the profit and loss account.
3 (g).Financial instruments
The Company only enters into basic financial instrument transactions that result in the recognition of
financial assets and liabilities like trade and other debtors and creditors and amounts owed by and to group
undertakings. 
Financial assets that are measured at cost and amortised cost are assessed at the end of each reporting
period for objective evidence of impairment. If objective evidence of impairment is found, an impairment
loss is recognised in the Statement of comprehensive income.
For financial assets measured at amortised cost, the impairment loss is measured as the difference between
an asset's carrying amount and the present value of estimated cash flows discounted at the asset's original
effective interest rate. If a financial asset has a variable interest rate, the discount rate for measuring any
impairment loss is the current effective interest rate determined under the contract.
For financial assets measured at cost less impairment, the impairment loss is measured as the difference
between an asset's carrying amount and best estimate of the recoverable amount, which is an approximation
of the amount that the Company would receive for the asset if it were to be sold at the balance sheet date.
Financial assets and liabilities are offset and the net amount reported in the Statement of Financial Position
when there is an enforceable right to set off the recognised amounts and there is an intention to settle on a
net basis or to realise the asset and settle the liability simultaneously.
3 (h).Defined benefit plans
A defined benefit plan is a post-employment benefit plan other than a defined contribution plan. The
Company’s net obligation in respect of defined benefit plans is calculated by estimating the amount of
future benefit that employees have earned in return for their service in prior periods; that benefit is
discounted to determine its present value. The fair value of any plan assets is deducted. The Company
determines the net interest expense (income) on the net defined benefit liability (asset) for the period by
applying the discount rate as determined at the beginning of the annual period to the net defined benefit
liability (asset) taking account of changes arising as a result of contributions and benefit payments.
The discount rate is the yield at the balance sheet date on AA credit rated bonds denominated in the
currency of operations, and having maturity dates approximating to the terms of the Company’s
obligations. A valuation is performed annually by a qualified actuary using the projected unit credit
method. The Company recognises net defined benefit plan assets to the extent that it is able to recover the
surplus either through reduced contributions in the future or through refunds from the plan.
Changes in the net defined benefit liability arising from employee service rendered during the period, net
interest on net defined benefit liability, and the cost of plan introductions, benefit changes, curtailments and
settlements during the period are recognised in the income statement.
Remeasurement of the net defined benefit liability/asset is recognised in other comprehensive income in
the period in which it occurs.

Notes to the Financial Statements (continued)
Year ended 31 December 2024
3.Accounting policies (continued)
3 (i).Defined contribution plans
A defined contribution plan is a post-employment benefit plan under which the Company pays fixed
contributions into a separate entity and will have no legal or constructive obligation to pay further amounts.
Obligations for contributions to defined contribution pension plans are recognised as an expense in the
income statement in the periods during which services are rendered by employees.
3 (j).Cash and cash equivalents
Cash and cash equivalents include cash in hand, deposits held at call with banks, other short-term highly
liquid investments with original maturities of three months or less.
3 (k).Bank overdrafts
Bank loans and overdrafts comprise bank overdrafts forming an integral part of the Company's cash
management and are repayable on demand.
3 (l).Critical accounting estimates and assumptions
The Company makes estimates and assumptions concerning the future. The resulting accounting estimates
will, by definition, seldom equal the related actual results. The estimates and assumptions that have a
significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the
next financial year are addressed below.
Going concern (for details of assumptions adopted see note 3 (b))
Defined benefit plans (for details of assumptions adopted see note 3 (h))

The amount recognised in profit or loss as an expense in relation to defined contribution plans was
£8,259,000 (2023: £7,231,000). There is an accrual of £nil (2023: £nil) included in the statement of
financial position relating to the plan at the year end.
Defined benefit plans
The Company operates a funded pension scheme providing a variety of benefits for different categories of
membership. Up to 31 March 2005 the majority of the benefit was held in defined benefit (the "Defined
Benefit Scheme") with some benefit held in defined contribution (the "Defined Contribution Scheme").
From 1 April 2005, the "Defined Benefit Scheme" was closed to future accrual. Instead employees were
given the option to contribute to the "Defined Contribution Scheme". The benefit now held in the "Defined
Benefit" fund is frozen and is increased annually in line with inflation.
The assets of the Plan are held separately from those of the Company.
The defined benefit pension plan of the Company is jointly guaranteed by Kellogg Brown & Root Holdings
Limited (Principal Guarantor), Kellogg Brown & Root Holdings (U.K.) Limited (First Additional
Guarantor) and Kellogg Brown & Root Limited (Second Additional Guarantor).
A full actuarial valuation was carried out as at 31 March 2021 and updated to 31 December 2024 by a
qualified independent actuary.

20.Parent undertaking support
Kellogg Brown & Root Holdings (U.K. ) Limited acts as a guarantor (First Additional Guarantor) for the
Kellogg Brown & Root (U.K.) Limited defined benefit pension plan scheme, along with Kellogg Brown &
Root Holdings Limited (Principal Guarantor) and Kellogg Brown & Root Limited (Second Additional
Guarantor).
The Co-Guarantors have jointly and severally guaranteed that if the assets of the plan become insufficient
to secure the benefits in full to the beneficiaries, each beneficiary would receive the benefits to which he or
she is entitled to in full. The guarantee is split equally between Kellogg Brown & Root Limited (20%) and
Kellogg Brown & Root Holdings (U.K.) Limited (20%) with Kellogg Brown & Root Holdings Limited
guaranteeing the remaining 60% in accordance with an arrangement reached between these companies.
KBR, Inc. has agreed to guarantee the obligation of the Company to make payments to the Kellogg Brown
& Root (U.K.) Limited defined benefit pension plan up to the guaranteed amount, so that if the Company
does not pay its guaranteed obligation KBR, Inc. shall, within two weeks of demand by the Trustees, pay
that amount as if it was the principal obligator. The guaranteed amount means the lesser of A, B or C,
where:
A. £250,000,000
B. the estimated shortfall in the assets of the Plan if the Plan’s liabilities were to be secured through
buy-out policies with one or more insurers
C. the greater of (i) the shortfall in the Plan’s assets required to meet the Plan’s liabilities calculated
using the assumptions used in the technical provisions basis set out in the Plan’s Statement of
Funding Principles except that the pre- and post-retirement discount rate used for that calculation
will be equal to gilts plus 25 basis points and (ii) £150,000,000
There is also a further guarantee in the form of a legal charge over the Aspire contract. On insolvency of
KBR, Inc. the shares owned by KBR, Inc. in Aspire Defence Services Limited, KBR (U.K.) Investments
Limited, KBR (Aspire Construction) Holdings No. 2 Limited, KBR (Aspire Construction Ventures)
Holdings No. 2 Limited, KBR (Aspire Services) Holdings No. 2 Limited and KBR (Aspire Services
Ventures) Holdings No. 2 Limited would transfer to the Kellogg Brown & Root (U.K.) Limited defined
benefit pension plan scheme. The Kellogg Brown & Root (U.K.) Limited defined benefit pension plan
scheme will have access to this guarantee until the Scheme Actuary has calculated that the Scheme has
been “105% Funded” at the most recent Actuarial Valuation or a subsequent Quarter Date in respect of the
most recent Actuarial Valuation and also at the two full Quarter Dates immediately following that Quarter
Date. “105% Funded” means that the Scheme Actuary has calculated that the Scheme’s assets are at least
105% of the Scheme’s liabilities, calculated using the assumptions in the technical provisions basis set out
in the Scheme’s Statement of Funding Principles except that the pre- and post-retirement discount rate used
for that calculation will be equal to gilts plus 50 basis points. For this purpose the assets will exclude the
value of the legal charge over the Aspire contract.
