Results in brief

1. We monitor the underlying financial performance of the Group using alternative performance measures. These measures are not defined in International Financial Reporting Standards (IFRS) and therefore are considered to be non-GAAP (Generally Accepted Accounting Principles) measures. Accordingly, the relevant IFRS measures are also presented where appropriate. The purposes and definitions of non-GAAP measures are provided in the Financial glossary on page 46.

2. Growth rate on a constant currency basis.

3. Growth rate on a reported currency basis.

Charles Woodburn, Chief Executive, said: "We've delivered a strong financial performance in the first half of the year, thanks to the outstanding efforts of our employees.

"Our global footprint, deep customer relationships and leading technologies enable us to effectively support the national security requirements and multi-domain ambitions of our government customers in an increasingly uncertain world.

"With a record order backlog and good operational performance, we're well positioned to continue delivering sustained growth in the coming years, giving us confidence to continue investing in new technologies, facilities, highly-skilled jobs and in our local communities."

Strategic progress

During the first half of the year, we have continued to deliver against our strategic priorities to: drive operational excellence; continuously improve competitiveness and efficiency; and advance and further leverage our technology. Examples of this in the period include:

·    On 13 March, as part of the AUKUS trilateral programme between Australia, the United Kingdom and the United States, it was announced that BAE Systems will play a key role in helping Australia to acquire its first nuclear powered submarines. The three nations will deliver a trilaterally-developed submarine, based on the UK's next-generation design, incorporating technology from all three nations. Australia and the UK will operate SSN-AUKUS as their submarines of the future, with construction expected to begin this decade.

·    BAE Systems has received new investment from the Ministry of Defence to boost technologies for the UK's future combat aircraft. The contract extension, worth £0.7bn, will build on the innovative science, research and engineering already completed under the first phase of the contract delivered by UK Tempest partners BAE Systems, Leonardo UK, MBDA UK and Rolls-Royce.

·    BAE Systems and Heart Aerospace, a Swedish electric airplane maker, announced a collaboration to define the battery system for Heart's ES-30 regional electric airplane. The battery will be the first-of-its-kind to be integrated into an electric conventional take-off and landing (eCTOL) regional aircraft, allowing it to efficiently operate with zero emissions and low noise.

·    BAE Systems and Microsoft have signed a strategic agreement aiming to support faster and easier development, deployment and management of digital defence capabilities for our customers.

Operational highlights

·    On 24 May, the Czech Republic awarded BAE Systems Hägglunds a contract to produce 246 CV90 MkIV infantry fighting vehicles in seven different variants. The contract is valued at £1.8bn. The CV90s will be developed and delivered through an industrial partnership with Czech industry to meet the requirements of the Czech Ministry of Defence and the intention of maintaining national sovereignty for the Czech Republic.

·    In Electronic Systems, our newest state-of-the-art facilities, which were recently opened in: Manchester, New Hampshire; Cedar Rapids, Iowa; and Austin, Texas, are now providing world-class work environments that support innovation, production and teamwork, which will help us to continue to deliver cutting-edge technology to our customers.

·    Our Combat Mission Systems business, within our Platforms & Services sector, once again received the James S. Cogswell Outstanding Industrial Security Achievement Award from the Defense Counterintelligence and Security Agency (DCSA) for two of its facilities. This award has a rigorous selection process with only 19 facilities receiving the award from around 13,000 cleared facilities.

·    In our Air sector, activity on our Qatar Typhoon and Hawk programmes continued. Four further Typhoon deliveries took place in the period, with a total of 12 aircraft now in service with the Qatar Emiri Air Force.

·    MBDA has been contracted by the Polish Armament Agency to supply Launchers and Common Anti-Air Module Missiles (CAMM) for Poland's PILICA+ Air Defence upgrade programme. The contract is the largest European short-range Air Defence acquisition programme in NATO.

·  In Maritime, the fifth Astute class submarine, HMS Anson, left our Submarines site in Barrow-in-Furness during February to begin sea trials with the Royal Navy. The steel cut ceremony for the fourth of eight Type 26 frigates, HMS Birmingham, took place in April.

Brad Greve, Group Finance Director said: "This is a strong set of half-year results delivering good sales and earnings growth, and giving us confidence to increase our year-end guidance for sales, underlying EBIT, underlying earnings per share and free cash flow. The record order backlog and continued good operational performance gives us more visibility and confidence in our three financial priorities - sales growth, margin expansion and high sustained cash conversion, operating under a disciplined capital allocation policy."

2023 Upgraded Group guidance

While the Group is subject to geopolitical and other uncertainties, the following upgraded guidance is provided on current expected operational performance. The guidance is based on the measures used to monitor the underlying financial performance of the Group. Reconciliations from these measures to the financial performance measures defined in IFRS are provided in our financial review on pages 9 to 15.

Sales guidance is increased by 200 bps to 5% to 7%, reflecting the accelerated spend profile on the Dreadnought programme and good demand and operational performance across all sectors.

Underlying EBIT guidance is increased by 200 bps to 6% to 8%, reflecting the sales profile and good operational performance.

Underlying earnings per share guidance is increased by 500 bps to 10% to 12%, reflecting higher profit, higher interest income and a reduction in the expected tax rate to 19%.

Cash generation for the first half of the year was strong, driven by advance payments, and is expected to be maintained through the year and we are therefore increasing our in-year free cash guide by £600m to >£1.8bn.

Our three-year cumulative free cash flow guidance has been upgraded, as shown in the table below.

Group guidance

Guidance is provided on the basis of an exchange rate of $1.24:£1, which is in line with the actual 2022 exchange rate, and therefore guidance is the same for both reported and constant exchange rates.

·    Underlying finance costs c.£220m

·    Effective tax rate c.19%

·    Non-controlling interests c.£80m

Sensitivity to foreign exchange rates: the Group operates in a number of currencies, the most significant of which is the US dollar. As a guide, a 5 cent movement in the £/$ exchange rate will impact sales by c.£400m, underlying EBIT by c.£55m and underlying earnings per share by c.1p.

Interim management report

Half-year overview

We have delivered a strong set of half-year results building on the operational and financial performance momentum of recent years. In the first half of 2023, we have:

·   continued to assist our customers in delivering urgent mission critical capability;

·   sustained good operational performance and cash flow generation;

·   secured £21.1bn of orders to set a record order backlog of £66.2bn;

·   delivered increased sales and profit, and effectively managed our supply chain;

·   continued to invest in our people, R&D and capital expenditure to underpin our growth outlook;

·   advanced our ESG agenda and engagement across our stakeholders;

·   made strong progress against our three-year £1.5bn share buyback programme, and announced a further three-year share buyback programme of up to £1.5bn expected to commence after completion of the current programme;

·   made significant long-term strategic progress with the AUKUS announcement and advanced discussions with our international partners on the Global Combat Air Programme (GCAP) in line with the trilateral government agreements made at the end of 2022; and

·   further developed a number of industry collaborations across several domains.

Our markets - increasing exposure to structurally growing major defence markets

In the elevated global threat environment, our international presence and diverse portfolio of products and services provides us with positive differentiation and high visibility for top-line growth in the coming years, along with a significant opportunity pipeline.

The AUKUS announcement in March 2023 is significant for the Group. Together with the GCAP announcement in December 2022, with Japan and Italy, these multi-national endeavours further highlight our global reach and the scale and longevity of our business. As always, we are working closely with our customers to deliver on their critical long-term programmes, which are reflective of a structural upwards shift in defence spending in our addressable markets.

In the US, the President's 2024 Budget Request increased the defence budget by over 3% above
FY 2023 base levels to $842bn (£662bn) and we remain well aligned to US National Defense Strategy priorities.

In the UK, the Integrated Defence Review refresh provided a further increase to defence spending, with the uplifts particularly focused on submarines and munitions, and an expectation to reach 2.25% of GDP by 2025. The recently published refresh of the Defence Command Paper reaffirmed the new national aspiration to invest 2.5% of GDP on defence when economic circumstances allow and committed additional funding on munitions over the coming decade.

In Europe, Finland joined NATO on 4 April 2023 and many countries continue to increase their annual and long-term defence spending plans as they look to enhance, recapitalise and replenish their capabilities to meet NATO commitments. We are well placed to continue to benefit through our position on Eurofighter Typhoon, our shareholding in MBDA, our BAE Systems Hägglunds and Bofors businesses in Sweden, as well as through US Foreign Military sales.

In the Middle East, we have long-standing relationships at Government and company level. Defence and security remains a priority in the region and we are well positioned through existing long-term contracts. We are progressing a number of opportunities with existing customers for new products and services. 

2023 operational performance

Overall operational performance was good across all Sectors in the first half and we continued to effectively manage the macroeconomic impacts of supply chain and inflationary pressures. We expect to deliver year-on-year margin expansion at the Group level, through a combination of expected continued good programme performance, business mix and by driving our operational efficiency and simplification programmes.

A significant amount of BAE Systems equipment has been provided by our government customers to Ukraine and, as the war in Ukraine continues, we remain closely engaged with our customers around the world to provide effective ongoing support.

Advancing and further leveraging our technology

Our focus on technology continues to be aligned with the national defence strategies of our major markets as our customers address the evolving global threat environment. Across the domains of air, land, sea, space and cyber, BAE Systems is investing in transformational technologies that advance state-of-the-art capabilities in defence systems. Artificial Intelligence (AI) is also becoming more important in every area, from design and manufacturing through to certain aspects of vehicle control. The first half of the year has seen significant progress in these areas. Our efforts to expand our portfolio of uncrewed platforms includes the launch of the Strix™ Tactical UAS concept, alongside collaborations with strategic university partners to develop new AI engineering capabilities.

We are continuing to build our digital footprint by combining our own expertise, which includes previous acquisitions such as Pitch Technologies and Bohemia Interactive Simulations, with that of innovative start-ups, such as Hadean, to develop next-generation synthetic environments. These environments, underpinned by our understanding of the operational challenges our customers face in all domains, will enhance both our internal product development and the services, such as training, that we offer to our customers. As part of this approach, we have a signed strategic agreement to collaborate with Microsoft, aiming to support faster and easier development, deployment and management of digital defence capabilities in an increasingly data-centric world.

In the domestic security domain, in April we announced our partnership with the Home Office to develop data analysis technology designed to help protect the UK's border. This is part of our digital transformation work with UK Government to connect and secure civil networks.

2023 half-year financial performance and guidance

We have delivered a strong set of half-year financial results and have made progress against our three financial priorities of: sales growth, margin expansion and high sustained cash conversion.

On a constant currency basis, sales growth was 11%, with all sectors delivering sales growth in the first half. Acceleration of funding on the Dreadnought programme drove Maritime's growth, whilst our Platforms & Services sector posted growth in Hägglunds, Ship Repair, and higher activities at our Holston munitions location. The Air sector saw higher activity on Tempest along with MBDA and air support volumes. Electronic Systems growth was led by continued recovery in civil aviation, power and propulsion and electronic combat systems. The Cyber & Intelligence business grew as a result of increased classified, sustainment and systems integration work in the Intelligence & Security business, while, outside the US, we saw a sharp increase in National Security cyber sales.

Revenue growth in the first half of the year was up 13%, on a reported currency basis, reflective of the same drivers behind the increase in sales for the period.

Underlying EBIT was up 10%, to £1.3bn, and underlying earnings per share was up 17% to 29.6p, both on a constant currency basis. Operating profit increased 20% to £1.2bn, on a reported currency basis. The Air sector posted the highest margin expansion in the period, whilst Platforms & Services also saw an increase in its return on sales in the first half. Maritime's return on sales reflects the accelerated funding on the Dreadnought programme, which trades in a regulated profit environment. As expected, the margin reduction in the Cyber & Intelligence sector reflects the additional investments being made in the business around space and multi-domain networking.

The growth in underlying earnings per share has also been impacted by the ongoing share buyback programme, with an additional 40.5m shares repurchased and cancelled in the first half.

Order intake, at £21.1bn, was up 16% on a constant currency basis, leading to a record order backlog of £66.2bn. Details of awards in the period are included in the segmental reviews on pages 16 to 25, the three largest orders were:

·    In our Platforms & Services business, BAE Systems Hägglunds received a contract award from the Czech Republic to produce 246 CV90 MkIV infantry fighting vehicles in seven different variants. The contract is valued at £1.8bn.

·    In Air, we have agreed with the Saudi Arabian Government to continue to provide Salam Typhoon support services for a further five years through to the end of 2027, valued at £3.7bn.

·    In Maritime, we received an order of £2.4bn in the period for the continued Delivery Phase 3 activity on the Dreadnought class submarine programme.

We expect continued strong order flow for the remainder of the year.

Free cash flow of £1,070m was driven by the good operational performance and order flow generating a number of advance customer payments.

Reflecting this strong performance in the first half of the year, we have upgraded the 2023 full-year Group Guidance for sales, underlying EBIT, underlying earnings per share and free cash flow, as reported in full on page 3 of this report.

Balance sheet and capital allocation

BAE Systems closed the half-year with a strong balance sheet, featuring a cash position of £3.2bn, net debt (excluding lease liabilities) of £1.8bn and a net pension position in an accounting surplus, by virtue of the Group's funding commitments over the years and the higher interest rate environment.

We maintain a capital allocation policy that prioritises investing in people, equipment and facilities, and R&D and provides for returning value to shareholders through dividends. Investments in acquisitions will continue to be considered where market conditions are right, and where they deliver on the Group's strategy and offer long-term value.

The Company can also return cash to shareholders in the form of share buybacks. In July 2022, the Company announced a three-year share buyback programme of up to £1.5bn. As at 30 June 2023, the Company had repurchased 123.5m shares under this programme in aggregate at a total price, including transaction fees, of £1.0bn, with 40.5m shares repurchased since 1 January 2023 at a total price, including transaction fees, of £0.4bn. The directors have also approved a further share buyback programme of up to £1.5bn. This further programme is expected to commence after completion of the current buyback programme and complete within three years of its commencement.

Our ESG agenda

In 2023, we are progressing our four key pillars of focus: addressing climate risks; ideas, innovation and technology; creating opportunity for people and communities; and success through partnering. We shall provide a progress update against these at our annual ESG investor event later in the year.

Global events have demonstrated the need for strong defence and security in the face of aggression by nation states. At BAE Systems, we provide critical capabilities and support to our government customers and their allies to fulfil their primary obligations to keep citizens safe, as well as providing important economic and social contributions through the provision of sustainable high-quality jobs.

A recent independent report from Oxford Economics showed that, in 2022, we contributed £11.1bn to UK Gross Domestic Product (GDP) and supported 132,000 full-time equivalent jobs across the UK. The report also showed that we spent £4.1bn with around 6,000 suppliers in the UK. We also exported £3.7bn of goods and services, almost 0.5% of all UK exports.

Sustainability is one of our five focus areas for technology innovation in the Group. Our ambition is to deliver more sustainable products without compromising performance, even enhancing performance where possible.

Additionally, our capability development and investment in furthering our sustainable technologies continues to make good progress and in the first half we announced a collaboration with Heart Aerospace, a Swedish electric airplane maker, to define the battery system for Heart's ES-30 regional electric airplane. The battery will be the first-of-its-kind to be integrated into an electric conventional take-off and landing regional aircraft.

Board changes

As previously announced, Sir Roger Carr stood down as Chairman of the Board and Non-executive director at the AGM on 4 May 2023, having served his full allowable term. He was succeeded by
Cressida Hogg, who has served as a Non-executive director of the Company and Chair designate since
1 November 2022.

Summary investment points

As we stated at the start of the year, and have reinforced in the year to date, we see significant potential in the years ahead due to:

·   our continued focus on operational excellence underpinned by a robust operating model;

·   continued investment in the business to support future growth;

·   a large order backlog providing the foundation for growth over the medium term;

·   leading technology solutions for our customers;

·   the strength of our diversity across geographies and technology;

Income statement summary

1. The purposes and definitions of non-GAAP measures are provided in the Financial glossary on page 46.

Sales¹ in the first half increased by £1.4bn to £12.0bn (2022 £10.6bn), an 11% increase on a constant currency² basis.

Revenue increased to £11.0bn (2022 £9.7bn), an increase of 13%.

Underlying EBIT¹ increased to £1,258m (2022 £1,112m), giving a steady return on sales of 10.5% (2022 10.5%).

Operating profit increased to £1,233m (2022 £1,028m) and includes a gain from adjusting items of £48m (2022 charge of £8m).

Adjusting items¹ in 2023 reflects a gain of £48m, comprising a settlement gain on a US pension annuity buy-out of £51m, offset by charges relating to historical acquisitions and disposals of £3m. 2022 comprised a charge of £8m related to historical business transactions.

Amortisation of programme, customer-related and other intangible assets was £56m (2022 £51m), the increase being driven by amortisation charges from businesses acquired during 2022.

Net finance costs for the Group amounted to £35m (2022 £249m). The underlying interest charge¹ for the Group was £116m (2022 £117m), offset by a net fair value gain of £62m (2022 charge of £113m) in respect of foreign exchange and financial derivatives.

Taxation expense of £193m (2022 £132m) reflects the Group's underlying effective tax rate for the period of 18%, adjusted for the impact of tax on adjusting items and of the UK tax rate adjustment.

The calculation of the underlying effective tax rate is shown in note 4 on page 39.

1. The purposes and definitions of non-GAAP measures are provided in the Financial glossary on page 46.

2. Current period compared with prior period translated at current period exchange rates.

Underlying earnings per share¹ for the period increased by 17%, excluding the impact of exchange translation, to 29.6p (2022 24.5p).

Basic earnings per share increased to 31.8p (2022 19.6p). The increase was driven by the improved underlying performance, gains on adjusting items, fair value movements on financial instruments and the ongoing impact of share buybacks under the 2022 buyback programme.

1. The purposes and definitions of non-GAAP measures are provided in the Financial glossary on page 46.

2. The tax impact is calculated using the underlying effective tax rate of 18% (2022 19%), with the exception of adjusting items which has been determined using the actual tax due on those items. The calculation of the underlying effective tax rate is shown in note 4.

1. The purposes and definitions of non-GAAP measures are provided in the Financial glossary on page 46.

Free cash flow¹ was an inflow of £1,070m (2022 £123m), reflecting strong operational performance and order flow generating a number of advance customer payments. Operating business cash flow¹ was an inflow of £1,307m (2022 £410m).

Net cash inflow from operating activities was £1,484m (2022 £493m).

Net capital expenditure and financial investment was a net outflow of £303m (2022 £201m), reflecting additional investment in new facilities across our Platforms & Services, Maritime and Cyber & Intelligence sectors.

Cash flows in respect of acquisitions, disposals and held for sale assets amounted to an outflow of £3m in relation to a historical business disposal. The outflow of £161m for the comparative period comprised cash paid for the acquisition of Bohemia Interactive Simulations, deferred consideration for historical acquisitions, plus cash classified as held for sale for the divestment of the Financial Services business which completed in October 2022.

Share buybacks amounted to £376m (2022 £130m) in the first half, reflecting repurchases under the £1.5bn share buyback programme that commenced in July 2022. The 2021 share buyback programme
for £500m was completed in February 2022, of which £130m was spent in the comparative period to
30 June 2022. In total, £884m (2022 £610m) has been returned to shareholders through share buybacks and dividends in the period.

There was a net cash outflow from derivative financial instruments of £182m (2022 £107m net inflow) arising from rolling hedges on balances with the Group's subsidiaries and equity accounted investments.

Net cash inflow from loans of £166m (2022 outflow of £400m) represented funds raised from a US private placement to fund the modern shiplift and land-level repair complex at our Jacksonville, Florida shipyard in the Platforms & Services sector. The outflow of £400m in the comparative period reflects repayment of a £400m bond in June 2022.

Foreign exchange translation primarily arises in respect of the Group's US dollar-denominated borrowings.

2. Taxation is managed on a Group basis.

Net debt

The Group's net debt (excluding lease liabilities)¹ at 30 June 2023 was £1,833m, a decrease of £190m on the position at the beginning of the period. This is primarily as a result of strong free cash flow performance, partially offset by increased shareholder returns through dividends and share buybacks which amounted to £884m (2022 £610m) in the period.

Cash and cash equivalents of £3,204m (2022 £3,107m) are held primarily for the repayment of debt securities, committed shareholder returns and management of working capital.

Going concern

After making due enquiries, the directors have a reasonable expectation that the Group has adequate resources to continue in operational existence for at least 12 months from the date of approval of this report and, therefore, continue to adopt the going concern basis in preparing the financial statements.

The Group continues to conduct ongoing risk assessments in relation to its business operations and liquidity. Demand from the Group's key customers remains strong, underpinned by our order backlog, programme positions and pipeline of opportunities across all sectors. The Group also continues to work with and support its supply chain to actively address the risk of disruption.

The Group's liquidity and solvency has remained strong. Cash flow forecasting is performed by the businesses on a monthly basis. The Group also monitors a rolling forecast of its liquidity requirements to ensure that there is sufficient cash to meet operational needs and maintain adequate headroom.

Having undertaken these assessments, the directors consider that the Group will be able to continue in operational existence for the foreseeable future. For this reason they continue to adopt the going concern basis in preparing the Group's Condensed Consolidated Interim Financial Statements.

Principal risks and uncertainties

Having considered recent geopolitical and macroeconomic events, the Group believes the principal risks and uncertainties facing the Group for the remainder of the year are included in, and are therefore unchanged from, those reported in the Annual Report 2022.

The Group's principal risks and uncertainties at 31 December 2022 were detailed on pages 119 to 125 of the Annual Report 2022, and related to the following areas: government customers, defence spending and terms of trade; international markets; contract risk, execution and supply chain; cyber security; competition in international markets; people; outbreak of contagious diseases; pension funding; climate change and the environment; laws and regulations; and acquisitions.

Accounting policies

On the 19 July 2023, the UK endorsed the amendments to IAS 12 Income Taxes, issued by the International Accounting Standards Board on 23 May 2023, which grants companies a temporary exemption from applying IAS 12 to the International Tax Reform: Pillar Two Model Rules. For the Half-yearly Report 2023, the Group has adopted the amendments to IAS 12.

No other new or amended standards which became applicable for the period ending 30 June 2023 had a material impact on the Group or required the Group to change its accounting policies.

Segmental review

The Group has five sectors which, together with HQ, make its six reporting segments as defined by
IFRS 8 Operating Segments.

1. The purposes and definitions of non-GAAP measures are provided in the Financial glossary on page 46.

Segmental performance: Electronic Systems

Electronic Systems, with 17,300 employees¹, comprises the US- and UK-based electronics activities, including electronic warfare systems, navigation systems, electro-optical sensors, military and commercial digital engine and flight controls, precision guidance and seeker solutions, next-generation military communications systems and data links, persistent surveillance capabilities, space electronics and electric drive propulsion systems.

Financial performance

-    Sales of £2.6bn increased 8% on a constant currency basis³, due to improvements in supply chain constraints in the period and stronger demand in our commercial aviation operations.

-    Return on sales was 15.1%, reflecting an expected lower profit weighting in the first half.

-    Operating business cash flow was £157m and reflects a more usual second half weighted business cycle.

-    Order backlog is at £8.1bn, after accounting for FX variances. Order intake in the period of £3.1bn reflects key awards such as a further five-year F-22 support contract from Lockheed Martin and multiple awards across the commercial aviation business.

3.     Current period compared with prior period translated at current period exchange rates.

Operational performance

We continued to experience strong demand amongst our customer base for Electronic Systems in the first half of 2023 as evidenced by our order generation. Operational initiatives, which the team developed during the pandemic to address challenges caused by the global shortage of microelectronics and labour shortages, are helping to mitigate the impacts of the supply chain constraints and we are seeing increased stability and an easing in some areas. We supported existing customers on key electronic warfare and precision guided munition production programmes, while pursuing and maturing new opportunities aligned to defence budgets and a growing global defence market.

In our commercial businesses, airline traffic and business travel is increasing, resulting in stronger demand for Original Equipment Manufacturer (OEM) deliveries and aftermarket services. Clean air regulations continue to drive the transportation industry toward alternative energy sources, such as our propulsion solutions, and we are seeing enhanced demand for our products.

Operational highlights

·    The F-35 Lightning II programme is delivering on Lot 15 electronic warfare (EW) systems and has delivered a cumulative total of over 1,250 EW systems. We are also supporting the Block 4 modernisation efforts under multiple contracts, including a recent contract for future Lot 17/18 production worth $491m (£398m).

·    We completed the development, integration, and first flight of the EC-37B Compass Call Cross Deck aircraft, targeted to enter formal developmental and operational testing by the end of the financial year.

·    In January, we conducted an Advanced Precision Kill Weapon System (APKWS^®) test event and demonstrated new capabilities for critical mission sets in support of US and allied forces.

·    Our newest state-of-the-art facilities which opened last year in: Manchester, New Hampshire; Cedar Rapids, Iowa; and Austin, Texas are now providing world-class work environments that support innovation, production, and teamwork, which will help us to continue to deliver cutting-edge technology to our customers.

Strategic and order highlights

·    We received a five-year follow-on Agile Sustainment for Raptor contract from Lockheed Martin to provide repair, technical, spares, and depot lay-in material support of the F-22. This long-term contracting approach provides continued cost-effective support of the subsystem to meet the aircraft availability.

Independent review report to BAE Systems plc

Conclusion

We have been engaged by the Company to review the condensed set of financial statements in the half-yearly financial report for the six months ended 30 June 2023 which comprises the Condensed consolidated income statement, Condensed consolidated statement of comprehensive income, Condensed consolidated statement of changes in equity, the Condensed consolidated balance sheet, Condensed consolidated cash flow statement and related notes 1 to 11.

Based on our review, nothing has come to our attention that causes us to believe that the condensed set of financial statements in the half-yearly financial report for the six months ended 30 June 2023 is not prepared, in all material respects, in accordance with United Kingdom adopted International Accounting Standard 34 and the Disclosure Guidance and Transparency Rules of the United Kingdom's Financial Conduct Authority.

Basis for Conclusion

We conducted our review in accordance with International Standard on Review Engagements (UK) 2410 "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Financial Reporting Council for use in the United Kingdom (ISRE (UK) 2410). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

As disclosed in note 1, the annual financial statements of the Group are prepared in accordance with United Kingdom adopted international accounting standards. The condensed set of financial statements included in this half-yearly financial report has been prepared in accordance with United Kingdom adopted International Accounting Standard 34, "Interim Financial Reporting".

Conclusion Relating to Going Concern

Based on our review procedures, which are less extensive than those performed in an audit as described in the Basis for Conclusion section of this report, nothing has come to our attention to suggest that the directors have inappropriately adopted the going concern basis of accounting or that the directors have identified material uncertainties relating to going concern that are not appropriately disclosed.

This Conclusion is based on the review procedures performed in accordance with ISRE (UK) 2410; however future events or conditions may cause the entity to cease to continue as a going concern.

Responsibilities of the directors

The directors are responsible for preparing the half-yearly financial report in accordance with the Disclosure Guidance and Transparency Rules of the United Kingdom's Financial Conduct Authority.

In preparing the half-yearly financial report, the directors are responsible for assessing the Group'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 the directors either intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so.

Auditor's Responsibilities for the review of the financial information

In reviewing the half-yearly financial report, we are responsible for expressing to the Company a Conclusion on the condensed set of financial statements in the half-yearly financial report. Our Conclusion, including our Conclusion relating to going concern, is based on procedures that are less extensive than audit procedures, as described in the Basis for Conclusion paragraph of this report.

Use of our report

This report is made solely to the Company in accordance with ISRE (UK) 2410. Our work has been undertaken so that we might state to the Company those matters we are required to state to it in an independent review report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company, for our review work, for this report, or for the conclusions we have formed.

Notes to the condensed half-yearly accounts

1. Preparation of the consolidated financial statements

Basis of preparation and statement of compliance

The annual financial statements of the Group will be prepared in accordance with UK-adopted International Accounting Standards (IAS), in conformity with the requirements of the Companies Act 2006. The condensed consolidated set of financial statements included in this Half-yearly Report have been prepared in accordance with UK-adopted IAS 34 Interim Financial Reporting and the Disclosure Guidance and Transparency Rules sourcebook of the UK's Financial Conduct Authority. These condensed consolidated financial statements do not comprise statutory accounts within the meaning of Section 435 of the Companies Act 2006 and should be read in conjunction with the Annual Report 2022. The comparative figures for the year ended 31 December 2022 are not the Group's statutory accounts for that financial year. Those financial statements have been reported upon by the Group's auditor and delivered to the Registrar of Companies. The report of the auditor was unqualified, did not include a reference to any matters to which the auditor drew attention by way of emphasis without qualifying their report and did not contain statements under Section 498 (2) or (3) of the Companies Act 2006.

The accounting policies adopted in the preparation of these condensed consolidated half-yearly financial statements to 30 June 2023 are consistent with the accounting policies applied by the Group in its consolidated financial statements as at, and for the year ended, 31 December 2022 as required by the Disclosure Guidance and

Transparency Rules of the UK's Financial Conduct Authority.

New and amended standards adopted by the Group

On the 19 July 2023, the UK endorsed the amendments to IAS 12 Income Taxes, issued by the International Accounting Standards Board on 23 May 2023, which grants companies a temporary exemption from applying
IAS 12 to the International Tax Reform: Pillar Two Model Rules. For the Half-yearly Report 2023, the Group has adopted the amendments to IAS 12.

No other new or amended standards which became applicable for the period ending 30 June 2023 had a material impact on the Group or required the Group to change its accounting policies.

Key Sources of estimation uncertainty

The application of the Group's accounting policies requires the use of estimates. In response to the potential impact of risks and uncertainties, the Group undertakes risk assessments and scenario planning in order to be able to respond to potential rapid changes in circumstances. The Group therefore considers a range of estimates and assumptions in the application of its accounting policies and management's assessment of the carrying values of assets and liabilities. In the event that these estimates or assumptions prove to be incorrect, there may be an adjustment to the carrying values of assets and liabilities. Potential areas of the Group's financial statements which could be materially impacted may include, but are not limited to:

Revenue and profit recognition

The Group accounts for revenue in accordance with IFRS 15 Revenue from Contracts with Customers. For most of the Group's contracts, revenue and associated margin are recognised progressively over time as costs are incurred, and as risks have been mitigated or retired.

The ultimate profitability of contracts is based on estimates of revenue and costs, including allowances for technical and other risks which are reliant on the knowledge and experience of the Group's project managers, engineers and finance and commercial professionals. Material changes in these estimates could affect the profitability of individual contracts. Revenue and cost estimates are reviewed and updated at least quarterly, and more frequently as determined by events or circumstances.

The long-term nature of many of the Group's contracts means that judgements are made in estimating future costs on a contract, as well as when risks will be mitigated or retired. The impact of global supply chain issues, volatility in global gas and energy prices, and the ongoing response to climate change, have increased uncertainty in relation to these judgements and estimates. The Group continues to work closely and collaboratively with its key customers to continue to deliver effectively on its contracts and commitments. However, the volume, scale, complexity and long-term nature of its programmes mean that a range of calculated potential sensitivities would be wide-ranging and not practicable to calculate. Owing to the ongoing uncertainty regarding the potential future impact of the current uncertainties, the Group's estimates and assumptions related to revenue recognition could be impacted by issues such as reduced productivity as a result of operation disruption, production delays and increased costs as a result of disruption to the supply chain, changing working practices to move towards net zero, or where there is uncertainty as to the recovery from customers of programme costs incurred.

In 2022, the Group recognised £0.3bn of revenue in respect of performance obligations satisfied or partially satisfied in previous years (2021 £0.3bn). This continues to provide an approximation of the potential revenue sensitivity arising as a result of management's estimates and assumptions for variable consideration, future costs, and technical and other risks, however may not reflect the full potential impact on the contract receivables and contract liabilities balances.

Post-employment benefit obligations

A number of actuarial assumptions are made in assessing the value of post-employment benefit obligations, including discount rate, inflation rate, and mortality assumptions. For each of the actuarial assumptions used there is a wide range of possible values and management estimates a point within that range which most appropriately reflects the Group's circumstances.

If estimates relating to these actuarial assumptions are no longer valid or change due to changing economic and social conditions, then the potential obligations due under these schemes could change significantly.

Discount and inflation rates could change significantly as a result of a prolonged economic downturn, monetary policy decisions and interventions or other macroeconomic issues. The impact of estimates made with regard to mortality projections may also change.

Similarly, the values of many assets are subject to estimates and assumptions, in particular those which are held in unquoted pooled investment vehicles. The associated fair value of these unquoted pooled investments is estimated with consideration of the most recently available valuations provided by the investment or fund managers. These valuations inherently incorporate a number of assumptions including the impact of climate change on the underlying investments. The overall level of estimation uncertainty in valuing these assets could therefore give rise to a material change in valuation within the next 12 months.

Furthermore, estimates are required around the Group's ability to access its defined benefit surpluses, and on what basis, which then determines the associated rate of tax to apply. Depending on the outcome, judgement is then required to determine the presentation of any tax payable in recovering a surplus.

Note 6 provides information on the key assumptions and analysis of their sensitivities.

Critical Judgements made in applying accounting policies

No critical judgements have been made in the process of applying the Group's accounting policies, other than those involving estimates, that have had a significant effect on the amounts recognised in the financial statements.

2.     Adjusting items were referred to as non-recurring items in the comparative period. No change has been made to the definition of these items, but the name has been changed to reflect that some items could be considered recurring in nature. Adjusting items in 2023 reflects a gain of £48m, comprising a settlement gain on a US pension annuity buy-out of £51m, offset by charges relating to historical acquisitions and disposals of £3m. 2022 comprised a charge of £8m related to historical business transactions.

4. Taxation expense

Taxation expense

Calculation of the underlying effective tax rate

The taxation expense has been determined by calculating an estimated annual tax rate for each country or entity, and then applying those rates to the half year profits or losses.

The Group's underlying effective tax rate is sensitive to the geographic mix of profits and may be impacted, from 2024 onwards, by the UK's substantive enactment of the Organisation for Economic Co-operation and Development's Global Anti-Base Erosion Model Rules (Pillar Two). For the Half-yearly Report 2023 the Group has adopted the International Accounting Standards Board's temporary exemption from applying IAS 12 to Pillar Two. At this stage the Group does not have sufficient information to determine the potential quantitative impact of
Pillar Two.

5. Earnings per share

1. The tax impact is calculated using the underlying effective tax rate of 18% (2022 19%), with the exception of adjusting items which has been determined using the actual tax due on those items. The calculation of the underlying effective tax rate is shown in note 4.

6. Post-employment benefits

Summary of movements in post-employment benefit obligations

Principal actuarial assumptions

The assumptions used are estimates chosen from a range of possible actuarial assumptions which, due to the long-term nature of the obligation covered, may not necessarily occur in practice.

For its UK pension schemes, the Group has used the Self-Administered Pension Schemes S3 mortality tables based on year of birth (as published by the Institute of Actuaries) for both pensioner and non-pensioner members, in conjunction with the results of an investigation into the actual mortality experience of scheme members and information on the demographic profile of the scheme's membership.

To allow for future improvements in longevity, the Continuous Mortality Investigation 2021 tables (published by the Institute of Actuaries) have been used (in 2022, the same tables were used), with an assumed long-term rate of future annual mortality improvements of 1.0% per annum (2022 1.0%), an initial rate adjustment parameter ('A') of 0.25% (2022 0.25%) in conjunction with a smoothing parameter ('S_k') of 7 for all members (2022 7). The Group has chosen to apply a weighting to the 2020 and 2021 data in recognition of the abnormal excess deaths as a result of COVID-19. No further adjustments have been made to improvements expected in future years. The impacts of COVID-19 will continue to be monitored and assessed at future reporting dates.

For the majority of the US schemes, the mortality tables used are a blend of the fully generational PRI-2012 White Collar table and the PRI-2012 Blue Collar table, both projected using Scale MP-2021.

Settlement gain

In May 2023 $1.2bn (£1.0bn) of the US defined benefit obligation liabilities were settled via a transfer to an insurance company. The premium of $1.1bn (£0.9bn) was approximately 95% of the IAS 19 liability carrying value, creating a one-off accounting gain of $63m (£51m). This gain has been recognised as an Adjusting item in the income statement.

Surplus recognition

A number of schemes are in an accounting surplus position. The surpluses have been recognised on the basis that the future economic benefits are unconditionally available to the Group, which is assumed to be via a refund. These have been recognised after deducting a 35% withholding tax which would be levied prior to the future refunding of any surplus and have been presented on a net basis as this is not deemed to be an income tax of the Group.

Sensitivity analysis

The sensitivity information has been derived using scenario analysis from the actuarial assumptions as at 30 June 2023 and keeping all other assumptions as set out above.

Financial assumptions

The estimated impact of changes in the discount rate and inflation assumptions on the defined benefit pension obligations, together with the estimated impact on scheme assets, is shown in the table below. The estimated impact on scheme assets takes into account the Group's risk management activities in respect of interest rate and inflation risk. The sensitivity analysis on the defined benefit obligation is measured on an IAS 19 accounting basis and, therefore, does not reflect the natural hedging in the discount rate used for funding valuation purposes.

Demographic assumptions

Changes in the life expectancy assumption, including the benefit of longevity swap arrangements, would have the following effect on the total net IAS 19 surplus:

7. Equity dividends

The directors have declared an interim dividend of 11.5p per ordinary share in respect of the period ended
30 June 2023, totalling approximately £382m. This will be paid on 30 November 2023 to shareholders registered
on 20 October 2023. The ex-dividend date is 19 October 2023. This is in line with our usual dividend timetable.

Shareholders who do not at present participate in the Company's Dividend Reinvestment Plan and wish to receive the interim dividend in shares rather than cash should complete a mandate form for the Dividend Reinvestment Plan and return it to the registrars for receipt no later than 3 November 2023.

Purchase of own shares

2022 buyback

In July 2022, the Company announced a three-year share buyback programme of up to £1.5bn (the '2022 buyback programme'). In the period to 31 December 2022, 82,997,065 ordinary shares were repurchased for a total price, including transaction costs, of £664m.

During 2023, the 2022 share buyback programme has continued, and on 1 June 2023 the Company commenced the third tranche of the 2022 share buyback programme. During the period to 30 June 2023, 40,460,554 ordinary shares were repurchased for a total price, including transaction costs, of £371m. These ordinary shares were subsequently cancelled, with the nominal value of ordinary shares cancelled deducted from share capital against the capital redemption reserve. This brings the total number of ordinary shares repurchased under the 2022 buyback programme to 123,457,619 for a total price, including transaction costs, of £1.0bn.

2021 buyback

In July 2021, the Company announced the details of a 12-month £500m share buyback programme (the '2021 buyback programme').

The 2021 share buyback programme was completed on 2 February 2022. During the period to 30 June 2022, 24,253,065 ordinary shares were repurchased for a total price, including transaction costs, of £132m. In total 87,525,938 ordinary shares were repurchased under the 2021 buyback programme for a total price, including transaction costs, of £503m.

8. Fair value measurement

Fair value of financial instruments

Certain of the Group's financial instruments are held at fair value.

The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the balance sheet date.

The fair values of financial instruments held at fair value have been determined based on available market information at the balance sheet date, and the valuation methodologies listed below:

-    the fair values of forward foreign exchange contracts are calculated by discounting the contracted forward values and translating at the appropriate balance sheet rates;

-    the fair values of both interest rate and cross-currency swaps are calculated by discounting expected future principal and interest cash flows and translating at the appropriate balance sheet rates; and

-    the fair values of money market funds are calculated by multiplying the net asset value per share by the investment held at the balance sheet date.

Due to the variability of the valuation factors, the fair values presented at 30 June may not be indicative of the amounts the Group will realise in the future.

Fair value hierarchy

The fair value measurement hierarchy is as follows:

-    Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities;

-    Level 2 - Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

-    Level 3 - Inputs for the asset or liability that are not based on observable market data (i.e. unobservable inputs).

Carrying amounts and fair values of certain financial instruments

All of the financial assets and liabilities measured at fair value are classified as level 2 using the fair value hierarchy, except for money market funds, which are classified as level 1, and other investments which are at a combination of level 1, level 2 and level 3. The total value of investments classified as level 2 and level 3 are immaterial. There were no transfers between levels during the period.

Financial assets and liabilities in the Group's consolidated balance sheet are either held at fair value or amortised cost. With the exception of loans, the carrying value of financial instruments measured at amortised cost approximates their fair value. The fair value of loans presented in the table above is derived from market prices, classified as level 1 using the fair value hierarchy.

9. Related party transactions

The Group has a related party relationship with its equity accounted investments, other investments and pension schemes. Transactions with related parties occur in the normal course of business, are priced on an arm's-length basis and settled on normal trade terms. The more significant transactions are disclosed below:

10. Contingent liabilities

The Group has entered into a number of guarantee and performance bond arrangements in the normal course of business. From time to time various Group undertakings are parties to legal actions, investigations and claims which arise in the normal course of business. Provision is made for any amounts that the directors consider may become payable. The Group takes legal advice as to the likelihood of success of claims and actions and no provision is made where the directors consider, based on that advice, that the action is unlikely to succeed, or that the Group cannot make a sufficiently reliable estimate of the potential obligation.

11. Events after the reporting period

There were no events after the reporting period which would materially impact the balances reported in this Report.

Financial glossary

We monitor the underlying financial performance of the Group using alternative performance measures (APMs). These measures are not defined in International Financial Reporting Standards (IFRS) and, therefore, are considered to be non-GAAP (Generally Accepted Accounting Principles) measures. Accordingly, the relevant IFRS measures are also presented where appropriate.

The Group uses these APMs as a mechanism to support period-on-period business performance and cash generation comparisons, and to enhance management's planning and decision making on the allocation of resources. The APMs are also used to provide information in line with the expectations of investors, and when setting guidance on expected future business performance. The Group presents these measures to the users to enhance their understanding of how the business has performed within the period, and does not consider them to be more important than, or superior to, their equivalent IFRS measures.
