Toby Courtauld, Chief Executive, said: "We are pleased to report on another successful operational performance, despite challenging political and economic conditions and fluctuating sector sentiment over the first half. With deep customer demand for prime, sustainable spaces in our core markets and an increasing shortage of such supply, we are well placed to capitalise; our leasing is strong, beating the valuer's estimates by 7% on average with our spaces currently under offer some 16% ahead. We expect our rents to continue rising, reaffirming our rental growth guidance, as we fill our well-timed and located, sustainable developments and refurbishments, growing our rent roll by some 99% from our existing commitments alone.

We added substantially to our platform for growth during the half through our successful £350 million rights issue in June and a further £400 million of debt issuance since then. With investment capacity in excess of £650 million, and asset pricing at or near cyclical lows, we acquired £106m of new HQ development and Flex opportunities in the West End at deep discounts to replacement cost. With a circa £1 billion pipeline of potential purchases under review, we expect to transact further in the second half, supplementing our exceptional on-site and near-term development programme which already covers 1.2 million sq ft and will generate significant surpluses.

In this context, with our deep and talented team, GPE is in great shape and is positioned for growth. We look to our exciting future with confidence."

1 All values include share of joint ventures unless otherwise stated 2 Leasing in period to 30 September 2024 3 On a like-for-like basis 4 In accordance with EPRA guidance. We prepare our financial statements using IFRS, however we also use a number of adjusted measures in assessing and managing the performance of the business. These include like-for-like figures to aid in the comparability of the underlying business and proportionately consolidated measures, which represent the Group's gross share of joint ventures rather than the net equity accounted presentation included in the IFRS financial statements. These metrics have been disclosed as management review and monitor performance of the business on this basis. We have also included a number of measures defined by EPRA, which are designed to enhance transparency and comparability across the European Real Estate sector, see note 8 to the financial statements. Our primary NAV metric is EPRA NTA which we consider to be the most relevant investor measure for the Group. 5 Pro forma for new RCF and term loan repayment

Half Year Results

Our business

Our business is accompanied by graphics (see Appendix 1)

Our investment activities

Activity levels in the investment market have remained low, as elevated interest rates have muted investor demand and supply has been limited with few buildings being brought to the market. Markets such as these provide opportunities to acquire at cyclically attractive pricing and since 1 April 2024 we have made three acquisitions adding to our Fully Managed and HQ development pipelines.

£350 million rights issue completed to further exploit investment market conditions

In June 2024, we completed a fully underwritten £350 million rights issue to seize the significant opportunity we are seeing emerge in our central London real estate investment markets. To date, we have exchanged or completed on three acquisitions, totalling £106.1 million.

Furthermore, we are currently tracking approximately £1.0 billion of acquisition opportunities (£1.4 billion in May including The Courtyard) which we believe are capable of being purchased at or below replacement cost, with GPE well placed to take advantage of these opportunities given our best in class workspaces, sustainability credentials and differentiated flex offering. Beyond this, there is a further £0.9 billion of opportunities on our watchlist.

Property swap to acquire The Courtyard, WC1

In April 2024, the Group exchanged contracts to buy The Courtyard, WC1 for £10.4 million of cash and through a property exchange of 95/96 New Bond Street, W1 for £18.2 million (£462 per sq ft; 69% below replacement cost). The Courtyard comprises 62,700 sq ft of vacant office and partially let retail space and is well suited to be repositioned into the Group's Fully Managed offering. The Courtyard is located in a prime West End location, around 400 metres from Tottenham Court Road Elizabeth line station, and is adjacent to Alfred Place, one of the Group's other Fully Managed buildings. We anticipate the refurbishment will deliver a 12.5% profit of cost and a yield on cost of 6.5%.

19/23 Wells Street, W1

In October 2024, we acquired 19/23 Wells Street, W1, for £19.0 million (£991 per sq ft, c.45% discount to replacement cost). Located in the heart of Fitzrovia, the 19,200 sq ft building comprises basement, ground and five upper floors. We intend to convert the space to our Fully Managed offer, together with transforming the ground floor space to deliver best-in-class amenity for its customers. We anticipate the refurbishment will deliver a yield on cost of 6.5%.

In tandem, GPE has secured a new 125-year headlease with Berners-Allsopp Estate (the Freeholder) for an additional £1.25 million. The new headlease will be granted in October 2024 and expire in October 2149.

The building is within walking distance of a number of GPE's existing holdings, including wells&more, Elsley House, Kent House and 7/15 Gresse Street and will add to a growing cluster of GPE Fully Managed buildings in Fitzrovia.

Whittington House, WC1

In November 2024, we acquired the long leasehold interest of Whittington House, WC1 for a headline price of £58.5 million (£785 per sq ft on current NIA, c.60% discount to replacement cost). GPE acquired the building through the acquisition of a special purpose company and is subject to further balance adjustment post completion. The building is currently let on a short-term basis, at an annual rent of c.£5.2 million with vacant possession expected in Q1 2025.

Located a short walk from the Tottenham Court Road Elizabeth line station, the 74,500 sq ft HQ building provides GPE with an exciting opportunity to create outstanding office spaces that draw upon its iconic Richard Seifert & Partners design, delivering eight floors of sustainable offices with market leading amenity, fronting on to the newly pedestrianised Alfred Place. The repositioned building will be delivered in Q1 2027 coinciding with a potentially historic level of undersupply of such space. We anticipate starting on site in Q1 2026 and expect to deliver a profit on cost of 16.1%, an ungeared IRR of 10.3% and a development yield of 6.8%.

Whittington House sits adjacent to GPE's existing holdings at 31/34 Alfred Place and opposite The Courtyard, WC1, thereby adding to a growing cluster of buildings that will provide GPE customers with a choice of spaces and amenity in this vibrant location.

Further opportunities to come

Looking ahead, we anticipate that market conditions will continue to provide opportunities to buy. Our focus remains on development and repositioning opportunities, buildings that would suit our Fully Managed offer and assets that are challenged from a sustainability perspective. Looking ahead, we also have around £565 million of future sales under consideration where we are completing our business plans, although we continue to believe that current market conditions are more favourable for buying rather than selling.

Our leasing activities

Strength In our occupational markets remains. In the six months to 30 September 2024 we continued to see strong leasing demand across our portfolio, with rents achieved outperforming the valuers' estimate by 7.0%. Key highlights include:

• 28 new leases were signed during the first half (2023: 37 leases), generating annual rent of £10.5 million (our share: £8.2 million; 2023: £10.5 million), with market lettings 7.0% above March 2024 ERVs (offices; 8.9%; retail 3.5%), including:

o 11 Fully Managed leases signed generating an additional £5.5 million of rent at an average £197 per sq ft (£238 per sq ft across the five West End deals), in total 8.9% ahead of March 2024 ERV; and

o 12 new retail leases securing £4.2 million of rent with market lettings 3.5% ahead of March 2024 ERV.

• Six rent reviews securing £6.7 million p.a. (our share: £4.2 million; 2023: £3.2 million) of rent were settled during the half year, 3.3% ahead of previous passing rent and 10.0% ahead of ERV;
• Total space covered by new lettings, reviews and renewals during the first half was 171,100 sq ft (2023: 182,900 sq ft);
• The Group's rent roll has increased by 2.1% to £109.8 million following a successful leasing period (not including the pre-let at 2 Aldermanbury Square, EC2); and
• 96% (by area) of the 75 leases with breaks or expiries in the twelve months to 30 September 2024 were retained, re-let, or are under offer, leaving only 1,600 sq ft still to transact.

The table below summarises our leasing transactions in the period:

Note: Includes joint ventures at share

Notable transactions during the six months included:

• In April 2024, we let the retail space at 141 Wardour Street, W1 to British luxury retail brand, REPRESENT, for its new London flagship store. The space comprises 5,000 sq ft across two floors, which will be its second store globally to date, following its LA opening in West Hollywood;
• At 16 Dufour's Place, W1, we renewed leases with existing customers on the 1st and 5th floors (5,100 sq ft) on a Fully Managed basis at an average rent of £249 per sq ft, an increase of 29% on the previous terms;
• Following the 22,500 sq ft letting to TK Maxx we announced last year, we have completed three new retail deals at Mount Royal, W1. The three retail brands that have signed new leases (totalling 20,000 sq ft) include the new immersive gaming brand, Activate (We Do Play); children's toy store, Keikoo; and Italian restaurant brand, Caffé Concerto. We have now secured new lettings on almost 60% of the space available at Mount Royal, W1 to great brands who all have a long-term vision for the location; and
• In September, we let 6,900 sq ft of retail space on a 10 year lease at 6/7 Portman Square, Orchard Court, W1 to luxury brand for professional-grade home appliances, Gaggenau. The brand will relocate from its current unit at 40 Wigmore Street, doubling its footprint occupying a prominent position on Portman Square.

At 30 September 2024, the Group's vacancy rate (including share of joint ventures) was 4.0%, up from 1.3% at 31 March 2024, due to recent completions of refurbishments. The average passing rent across our office portfolio was £85.20 per sq ft, up from £79.20 per sq ft at 31 March 2024 as we complete more Fully Managed deals.

Since 30 September 2024:

• We have signed an additional nine new leases, generating annual rent of £2.6 million (our share: £2.4 million), with market lettings 9.9% above March 2024 ERVs (offices; 10.2%; retail 2.6%); and
• Currently we have 144,200 ft of space under offer which would deliver approximately £7.1 million p.a. in rent (our share: £5.0 million), with market lettings 16.2% above March 2024 ERVs.

Our development activities and capex programme

Repositioning our buildings through redevelopment and refurbishment is a core part of our business model and presents a significant organic growth opportunity. Our forecasts suggest that the future supply of new spaces in London is severely constrained. We estimate that only 2.9 million sq ft p.a. of new space will be delivered on average over the next four years, in a market where the average take-up of new space is much greater, at 4.9 million sq ft p.a. Our significant capex programme is targeted to deliver new high quality space, with exemplary sustainability credentials, into these supportive markets through the delivery of new HQ developments and through the expansion of our Fully Managed spaces.

Three committed HQ development schemes

Our development works are making good progress at our fully pre-let 2 Aldermanbury Square, EC2, where we are substantially increasing the size of the building to 322,600 sq ft (up from 176,000 sq ft). Construction of the steel frame installation is progressing well and is now up to the 11th floor, with the main plant installation well underway in the basement areas. On completion the scheme will provide a number of public realm and amenity improvements that will have a positive impact on the local area. The new building will have best in class sustainability metrics and we are targeting BREEAM 'Outstanding'.

Whilst the development is currently anticipated to deliver a loss on cost from the commitment date of 12.6%, given market yield expansion driven valuation declines to date, from the 30 September 2024 valuation the scheme is expected to deliver around £27 million of future profit.

At 30 Duke Street, St James's, SW1 (formerly French Railways House & 50 Jermyn Street, SW1), we are nearing completion of the deconstruction of the existing buildings on the site. Our major office-led redevelopment will provide 68,600 sq ft (up from 54,700 sq ft) of new Grade A space. The scheme is designed to embrace the principles of the circular economy which includes retaining the existing foundations and basement and reusing the structural steel from the demolition of the previous building at 2 Aldermanbury Square, EC2. Once complete, the building will provide best in class, column free space together with high-specification amenities including a wellness suite, private terraces on the upper floors, a communal roof terrace with panoramic views, as well as the highest sustainability credentials. We have £84 million of costs to come and the scheme is anticipated to deliver a profit on cost of 24.1%, an ungeared IRR of 14.8% and a 6.5% development yield. The building is expected to complete in Q3 2026 and we are encouraged by the early leasing interest. With the valuers assuming an average office rent of £169 per sq ft, there is potential upside to these expected returns.

At Minerva House, SE1, our extensive refurbishment will take the overall commercial space to 143,100 sq ft, an increase of approximately 56% on the existing area. We are maintaining over 70% of the existing fabric and introducing innovative ways of working that will further reduce the overall embodied carbon impact of the development. As part of our activities, 20 tonnes of glass will be salvaged from site and used in the production of new glass; this is one of the first schemes in the country to participate in this truly circular and innovative process. Minerva House is also the first private development on the Thames to utilise a barge to remove materials from site during the first phase of the development. This pioneering approach will reduce the total number of heavy goods vehicles coming to site by 65% during the deconstruction phase, removing waste from an area with very high footfall, as well as reducing noise and air pollution in a congested, pedestrian heavy environment. The scheme is anticipated to complete in Q1 2027 and deliver a profit on cost of 19.1%, an ungeared IRR of 11.7% and a development yield of 7.0%.

In total, across the three on-site HQ development schemes we have committed expenditure to come of £353.0 million.

Four Fully Managed refurbishments; two recently completed

As we grow our flexible office offer, we are currently refurbishing four buildings to provide new dedicated Fully Managed spaces as well as converting a significant number of floors across our portfolio.

At 6 St Andrew Street, EC4, the newly rebranded 'SIX', completed in early November and offers 47,900 sq ft of newly refurbished office space comprising of workspaces ranging from 1,200 sq ft to 5,800 sq ft, across nine floors including a communal lounge and boardroom, a rooftop terrace, shared kitchen and wellness studio. SIX is within easy walking distance of Farringdon Elizabeth line station, Chancery Lane, Farringdon and Thameslink stations. The building is BREEAM Excellent, highly energy efficient, and is targeting NABERS 4.5* rating. Following the marketing launch earlier this month, early leasing interest is very encouraging.

At 31/34 Alfred Place, WC1, our extensive refurbishment of the building is nearing completion with our works at 31/32 completed earlier this month and 33/34 due to complete before the end of the year. Nestled in the heart of Fitzrovia, Alfred Place offers 41,500 sq ft of outstanding Fully Managed office space. Adjacent to The Courtyard, one of the Group's recent acquisitions, it is around 400 metres from Tottenham Court Road Elizabeth line station.

141 Wardour Street, W1 will provide 29,900 sq ft of new Fully Managed led space in the heart of Soho. Building on our success to date at nearby 16 Dufour's Place, W1, the building will deliver light-filled floorplates of 2,400 to 4,600 sq ft, terraces on the upper floors and excellent amenity space. The construction is expected to complete in Q2 2025 with capex to come of £15 million.

At Egyptian & Dudley House, SW1, we are comprehensively refurbishing the building to provide 25,600 sq ft of Fully Managed space. We are infilling lightwells to expand floorplates, creating new first-floor amenity space and creating an external terrace with garden to provide additional amenity and biodiversity. The scheme is expected to be delivered in Q2 2025 and will cost £18 million to complete.

These four buildings together will require around £41 million of capex to complete and, once delivered, will deliver annualised rent roll of £28.0 million and Net Operating Income (NOI) of £15.0 million. Today our committed Flex portfolio totals 525,000 sq ft (25% of our office portfolio).

In total, our seven on site schemes require capex of £394 million to complete and are expected to deliver a development surplus of £118.5 million. They will have a gross development value of c.£1.1 billion.

Further six schemes in the near-term pipeline

The Soho Square Estate, W1 is located in the heart of the West End at the eastern end of Oxford Street and backs onto Soho Square, just 100 metres from the new Tottenham Court Road Elizabeth Line station. The building was acquired with planning permission and we have reworked the designs and submitted them to Westminster to improve the quality of office and retail space, further increasing its attractiveness to prospective customers in a materially undersupplied market. The redevelopment will provide a best-in-class HQ office building on Soho Square with flagship retail fronting Oxford Street, arranged over basement, lower ground, ground and eight upper floors, with multiple private terraces and a communal roof terrace. We anticipate starting on site early 2025.

At St Thomas Yard, SE1 (formerly New City Court), we are currently in positive discussions with the London Borough of Southwark to extensively refurbish the existing space utilising a re-use and extend approach (similar to Minerva House). Our plan will increase the building to 185,300 sq ft of high quality, HQ offices, up from 98,000 sq ft today. We anticipate that the planning application will be submitted by the end of the year.

At the recently acquired Whittington House, WC1, once we achieve vacant possession in early 2025 we are planning to refurbish the building to deliver 74,500 sq ft of new Grade A offices, in close proximity to both the Courtyard and the recently completed 31/34 Alfred Place, both WC1. The building will be arranged over basement , ground and seven upper floors with a new terrace on the first floor together with a communal roof terrace with pavilion amenity space.

At the Courtyard, WC1, opposite 31/34 Alfred Place, we have recently submitted a planning application for a significant refurbishment of the building to deliver 62,700 sq ft of Fully Managed space. Our plans will add additional amenity on the roof, together with substantially reconfiguring the retail space on Tottenham Court Road. We anticipate commencing the refurbishment works in the first quarter of next year.

Together with Fully Managed conversions at 19/23 Wells Street and 7/15 Gresse Street, the near-term schemes will require capex to come of £401 million and we anticipate they will deliver a development surplus of around £107 million. They will have a gross development value of c.£0.9 billion.

Valuation

Valuation is accompanied by graphics (see Appendix 2 and 4)

The valuation of the Group's properties, including its share of joint ventures, was £2,496.5 million as at 30 September 2024 (31 March 2024: £2,331.2 million), reflecting a valuation increase of 0.8% on a like-for-like basis since 31 March 2024. At 30 September 2024, the wholly-owned portfolio was valued at £2,013.2 million (31 March 2024: £1,855.1 million) and the Group had three active joint ventures which owned properties valued at £483.3 million (our share) (31 March 2024: £476.1 million) by CBRE. At 30 September 2024, 72% of our portfolio was located in the West End.

Values inflecting, up 0.8%

The key drivers behind the Group's valuation movement for the six-month period were:

• Rental value growth - the continued demand for our best in class spaces has helped increase our rental values. Since the start of the financial year, across out portfolio rental values increased by 1.1% on a like-for-like basis, with our fully managed offices increasing by 1.4%, our long dated offices increasing by 3.0% and our overall office portfolio up by 1.2%, whilst our retail portfolio also increased by 0.9%;
• Portfolio management - a strong six months, 34 new leases, rent reviews and renewals were completed, securing £12.4 million (our share) of annual income, supporting the valuation. At 30 September 2024, the portfolio was 8.9% reversionary;
• A small upward movement in yields on a like-for-like basis (office +2 basis point; retail +4 basis points). At 30 September 2024, the portfolio true equivalent yield was 5.4% (West End: 5.3%; Rest of central London: 5.7%) and reversionary yield was 6.7%; and
• Developments - the valuation of our committed development properties decreased by 2.0% on a like-for-like basis to £275.4 million during the period.

Including rent from leases currently in rent free periods, the topped-up initial yield of the investment portfolio at 30 September 2024 was 3.9%, the same as the start of the financial year.

Whilst the overall valuation increased by 0.8% during the six months on a like-for-like basis, elements of the portfolio continued to show greater variation:

• Including developments, our West End portfolio (+1.6%) performed better than our rest of London portfolio (-1.2%) given stronger rental value growth of +1.5% in our West End portfolio compared to +0.5% in the rest of London portfolio on a like-for-like basis;
• Our Flex office space increased in value by 1.3%, of which Fully managed properties increased by 2.6% outperforming the Group's wider office space which increased by 0.8% in value, whilst our retail space outperformed offices increasing in value by 1.2% resulting from an overall softening in retail yields; and
• Our short leasehold properties (<100 years), which represent around 6% of the portfolio, continued to reduce in value down by 0.8% compared to an increase in value of 0.9% across the rest of the portfolio.

Near-term market outlook

Our markets are cyclical, as a result, we actively monitor numerous lead indicators to help identify key trends in our marketplace. Over the last six months, given reduced levels of inflation and the first of a number of anticipated reductions in interest rates, our property capital value indicators have improved marginally from those we reported in May. Investment market activity remains subdued, with the improved interest rate environment yet to feed into investor confidence. However, September saw a number of high profile properties brought to market suggesting that activity may pick up over the coming months.

In the occupational market, given the scarcity of high quality spaces in central London, particularly in the West End, we expect our leasing and rental performance of the portfolio in the first half of the year to continue, despite signs of weakening business confidence. Accordingly, we have maintained our rental value growth range for the financial year to 31 March 2025 at between 3.0% and 6.0%, prime offices 5.0% to 10.0%.

Our financial results

Our financial results are accompanied by graphics (see Appendix 3)

We prepare our financial statements using IFRS. We also use a number of Alternative Performance Measures (APMs) to help explain the performance of the business. These include quoting a number of measures on a proportionately consolidated basis to include joint ventures, as it describes how we manage the portfolio, like-for-like measures and using measures prescribed by the European Public Real Estate Association (EPRA). The measures defined by EPRA are designed to enhance transparency and comparability across the European real estate sector. Reconciliations of APMs are included in note 8 to the accounts.

We calculate net assets and earnings per share in accordance with EPRA's Best Practice Recommendations. The recommendations are designed to make the financial statements of public real estate companies clearer and more comparable across Europe, enhancing the transparency and coherence of the sector. EPRA's Best Practice Recommendations include three NAV metrics: EPRA Net Tangible Assets (NTA), Net Reinvestment Value (NRV) and Net Disposal Value (NDV). We consider EPRA NTA to be the most relevant investor metric for the Group and the primary measure of net asset value and relevant reconciliations between IFRS numbers and EPRA metrics are included in note 8 to the accounts.

£350 million rights issue completed

In June 2024, we completed a fully underwritten 3 for 5 rights issue to raise gross proceeds of approximately £350.3 million (£335.6 million net of expenses) through the issue of 152,320,747 new ordinary shares at a price of 230 pence each. The rights issue will allow GPE to seize the significant opportunity we see emerging in the central London commercial real estate space. The correction in asset values over recent years has resulted in central London commercial real estate trading in line with levels last seen in 2009 in real terms. Today, we have a deep pipeline of acquisition opportunities, including three deals agreed since April 2024, and a further £1.9 billion under review or on our watchlist.

We expect that the acquisitions and developments we acquire through the deployment of the proceeds of the rights issue will enhance shareholder returns, be accretive to both EPRA earnings and NTA per share and support our ambition to deliver a total accounting return of 10% plus over the medium term (before yield compression). Furthermore, with the macro-economic environment improving, there is further upside should property yields contract in a falling interest rate and improving rental growth environment.

Valuations up 0.8%; EPRA NTA marginally up to 475 pence per share

IFRS NAV per share and EPRA NTA per share at 30 September 2024 were 475 pence per share, an increase of 0.4% over the last six months compared to the pro forma net assets per share at 31 March 2024 adjusted for the rights issue (see note 8). The increase was largely due to the 0.8% like-for-like increase in the value of the property portfolio. The main drivers of the 2 pence per share increase in NTA from 31 March 2024 were:

• The increase of 5 pence per share arising from the revaluation of the property portfolio;
• EPRA earnings for the period of 2 pence per share increased NTA; and
• The final dividend of 5 pence per share reduced NTA.

The EPRA NTA increase of 0.4% (compared to the pro forma net assets per share at 31 March 2024) combined with the payment of last year's final dividend of £11.9 million (or 4.9 pence per share on the post rights number of shares), delivered a total accounting return for the six months to 30 September 2024 of +1.2% (2023: -13.1%).

At 30 September 2024, the Group's net assets were £1,928.6 million, up from £1,583.0 million at 31 March 2024, with the increase largely attributable to the receipt of the £335.6 million net proceeds from the rights issue and the increase in the property valuation. On a pro forma basis, EPRA NDV per share increased marginally to 488 pence at 30 September 2024, compared to 486 pence at 31 March 2024 (up 0.4%).

Earnings down in line with guidance and our portfolio activities

Revenue from our wholly-owned properties fell from £47.6 million to £44.9 million. Net rental income (including the spreading of lease incentives) reduced to £31.5 million compared to £35.0 million for the period to September 2023, as we achieved vacant possession of both development sites and floors for Fully Managed conversion across the portfolio. Service charge income fell from £8.9 million to £7.5 million due to lower service charge spend across the portfolio due to the continued conversion to Fully Managed spaces. Accordingly, Fully Managed services income rose from £2.7 million to £4.7 million as we continued to roll out and lease up our flexible office offer.

Adjusting for acquisitions, disposals and transfers to and from the development programme, like-for-like rental income (including from joint venture properties) increased by 0.4% on the prior period.

Cost of sales increased from £16.3 million to £16.8 million for the period to 30 September 2024, with the reduced levels of service charge expenses being offset by increased Fully Managed services as we continue to convert space to our Fully Managed offer.

Administration costs were £19.5 million, a decrease of £1.4 million on the prior year as we benefit from the team restructuring in the prior year and other associated cost savings, partially offset by higher provisions for share based payments.

EPRA earnings from joint ventures (excluding fair value movements) were £3.7 million, a decrease of £2.2 million from the prior year, largely driven by taking vacant possession of some floors at Gray's Inn Road as we commenced refurbishment of part of the building, as well as the insolvency settlement at Mount Royal in the prior year from the Arcadia administration not repeating. In total, our joint ventures delivered a IFRS profit before tax of £6.7 million (2023: loss of £39.6 million).

Gross interest on our debt facilities was £16.9 million, up £6.5 million on the prior period. This increase was primarily due to higher interest rates from the utilisation of the £250 million term loan, offset by higher underlying rates on lower amounts of drawn debt. We capitalised interest of £11.1 million (2023: £4.3 million), with the increase attributable to increased development activity and interest rates over the last 12 months. As a result, the Group had net finance costs (including interest receivable) of £3.9 million, a £0.5 million reduction on the prior period.

EPRA earnings were £8.5 million, 28.0% lower than for the same period last year. Revaluation gains together with EPRA earnings resulted in an IFRS profit after tax of £29.7 million (2023: loss of £253.4 million). The basic and diluted profit per share for the period was 8.1 pence, compared to a restated loss of 83.4 pence per share for 2023. Diluted EPRA earnings per share was 2.3 pence (2023: 3.9 pence), in line with guidance. We expect the Group's EPRA earnings for the current financial year to be broadly stable when compared to the prior financial year, however they will be lower on a per share basis given the higher number of shares in issue post the rights issue. Looking beyond 31 March 2025, we anticipate that the Group's earnings will return to growth as we complete, and let, our on-site development and refurbishment schemes.

Results of joint ventures

The Group's net investment in joint ventures was £495.3 million, an increase from £491.3 million at 31 March 2024, largely due to a small increase of 0.4% in value of the property portfolio on a like-for-like basis as well as the part repayment of partner loan balance in our GHS joint venture. Our share of joint venture net rental income was £7.7 million, down from £10.0 million last year primarily as a result of taking vacant possession of 144,000 sq ft at Gray's Inn Road, WC1 as we commenced an extensive refurbishment of the space. The underlying joint venture profits are stated after charging £1.0 million of GPE management fees, which were broadly flat year on year (2023: £0.6 million).

Overall, our three active joint ventures represent an important proportion of the Group's business. At 30 September 2024, joint ventures represented 19.4% of the portfolio valuation, 25.7% of net assets and 20.4% of rent roll (31 March 2024: 20.4%, 31.0% and 21.4% respectively).

Strong liquidity and low LTV; more than £670 million of cash and undrawn facilities; EPRA LTV 23.3%

The Group's consolidated net debt excluding restricted cash, decreased to £547.7 million at 30 September 2024, compared to £738.0 million at 31 March 2024. The decrease was largely due to receipt of the rights issue proceeds in the period of £335.6 million (net of expenses) offset by on-going development capital expenditure across the Group of £140 million in the six months. Group gearing decreased to 28.5% at 30 September 2024 (31 March 2024: 46.8%). Including cash balances in the joint ventures, total net debt was £526.2 million (31 March 2024: £713.5 million) equivalent to an EPRA loan to value of 23.3% (31 March 2024: 32.6%).

The Group is operating with substantial headroom over its debt covenants. At 30 September 2024, property values would have to fall by around 55% before covenant breach. Through the cycle, the Group aims to maintain a target LTV range between 10% and 35%, consistent with our low leverage levels over the last 10 years. Our interest cover ratio under our Group covenants was high at 3.5 times (covenant: 1.35 times).

In September 2024, we announced our first sterling denominated senior unsecured sustainable bond. The £250 million Bond has a term of seven years, bears interest at a rate of 5.375% and is rated Baa2 by Moody's Investor Services Ltd. Alongside our unsecured ESG-linked bank facilities, this sustainable Bond further diversifies our debt funding sources and has extended our weighted average debt maturity.

The Group's weighted average cost of debt, including fees, for the period was 5.3% (year to 31 March 2024: 4.1%). The weighted average interest rate (excluding fees) at the period end was 5.0%, up from 4.3% at 31 March 2024, following the repayment of £175 million 2.15% private placement notes in May 2024.

At 30 September 2024, including the new sterling bond, 94% of the Group's total debt was at fixed or hedged rates (31 March 2024: 87%) and our weighted average drawn debt maturity was 5.8 years (31 March 2024: 3.4 years).

In October 2024, we signed a new £150 million ESG-linked unsecured revolving credit facility (RCF) at a headline margin of 90 basis points over SONIA. The facility has an initial three-year term which may be extended to a maximum of five years at GPE's request, subject to bank consent.

In November 2024, we also repaid £175 million of the Group's £250 million term loan.

Following this activity, the Group has cash and undrawn credit facilities in excess of £670 million and our weighted average debt maturity extends to around seven years.

Taxation

The tax charge in the income statement for the half year was £0.2 million (2023: £nil) and the effective tax rate on EPRA earnings was 0% (2023: 0%). The majority of the Group's income is tax-free as a result of its REIT status. Other allowances were available to set against non-REIT profits.

As a REIT, the majority of rental profits and chargeable gains from our property rental business are exempt from UK corporation tax, provided we meet a number of conditions including distributing at least 90% of the rental income profits of this business (known as Property Income Distributions (PIDs)) on an annual basis. These PIDs are then typically treated as taxable income in the hands of shareholders. During the six months ended 30 September 2024, the Group paid a PID of £10.1 million.

The Group's REIT exemption does not extend to either profits arising from the sale of trading properties or gains arising from the sale of investment properties in respect of which a major redevelopment has completed within the preceding three years.

Dividends

The Board has declared an interim ordinary dividend of 2.9 pence per share (2023: 4.7 pence) which will be paid on 3 January 2025. None of this interim dividend will be a REIT Property Income Distribution (PID) in respect of the Group's tax-exempt property rental business.

Principal risks and uncertainties

The Group recognises that the successful management of risk is critical to enable delivery of the Group's strategic priorities. Ultimate responsibility for risk rests with the Board but the effective day-to-day management of risk is integral to the way the Group does business and its culture. The Board undertakes a robust assessment of the principal risks facing the Group on a regular basis.

The principal risks and uncertainties facing the Group for the remaining six months of the financial year remain in line with those detailed on pages 76 to 87 of the 2024 Annual Report with no material changes:

The Board and Executive Committee continue to regularly review the potential risks and impacts presented by the volatile economic backdrop, including in relation to inflation and higher underlying interest rates, as well as the potential impacts of geo-political tensions arising from events both in the Ukraine and the Middle East. The Board also continues to monitor for both short-term and potential longer-term structural changes in working practices, an evolving planning regime and the level and nature of demand for space in central London.

As a result of current levels of economic uncertainty, the Group's forecasts and business plans continue to be prepared under a variety of market scenarios to reflect a number of potential outcomes.

1 Basis of preparation

The information for the year ended 31 March 2024 does not constitute statutory accounts as defined in section 434 of the Companies Act 2006. A copy of the statutory accounts for that year has been delivered to the Registrar of Companies. The auditor's report on those accounts was not qualified, did not include a reference to any matters to which the auditors drew attention by way of emphasis without qualifying the report and did not contain statements under section 498(2) or (3) of the Companies Act 2006.

The annual financial statements of Great Portland Estates plc will be prepared in accordance with United Kingdom adopted international accounting standards and the requirements of the Companies Act 2006 as applicable to companies reporting under those 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 and in accordance with the Disclosure, Guidance and Transparency Rules of the United Kingdom's Financial Conduct Authority. The accounting policies and methods of computation applied are consistent with those applied in the Group's latest annual audited financial statements. The nature of the Critical Judgements and Key Sources of Estimation Uncertainty applied in the condensed financial statements have remained consistent with those applied in the Group's latest annual audited financial statements. The key source of estimation uncertainty is the valuation of the property portfolio. There were no critical judgements made in the preparation of the condensed financial statements. The Group's performance is not subject to seasonal fluctuations.

The Group has not applied IFRS 18 - Presentation and Disclosure in the financial statements, a new IFRS standard that has been issued but is not yet effective. The Directors expect that the adoption of the standard will have a material impact on the presentation of the financial statements of the Group for reporting periods beginning on or after 1 January 2027 and will also apply to comparative information.

Going concern

The Directors have considered the appropriateness of adopting the going concern basis in preparing the financial statements for the period ended 30 September 2024, with particular focus on the impact of geopolitical tensions and high interest rates on the macro-economic conditions in which the Group is operating. The Directors' assessment is based on the next 12 months of the Group's financial forecasts, including a going concern scenario which included the following key assumptions:

• a 17.3% decline in the valuation of the property portfolio from 30 September 2024; and
• an increase in EPRA earnings due to the delivery and letting of four on-site flex schemes.

The going concern scenario demonstrates that the Group over a period of at least 12 months:

• has significant liquidity to fund its ongoing operations, including the drawdown in September 2024 of a new £250 million sustainable sterling bond and in October 2024 of a new £150 million RCF, alongside £175 million partial early repayment of the £250 million term loan;
• is operating with significant headroom above its Group debt financing covenants;
• property values would have to fall by a further 24% before breach (or 55% from 30 September 2024 values);
• the Group does not project any breaches of its interest cover ratio, with minimum coverage of 6.91x (vs 1.35x covenant) throughout the going concern period; and
• has no debt maturities other than set out above.

Based on these considerations, together with extensive stress testing, available market information and the Directors' knowledge and experience of the Group's property portfolio and markets, the Directors have adopted the going concern basis in preparing the accounts for the period ended 30 September 2024.

2 Segmental analysis

The Directors have concluded that, based on the level of information provided to the Executive Committee, that its Fully Managed operations is an operating segment as defined by IFRS 8. Furthermore, given the revenue is in excess of 10% of wider Group revenue, the segment should be separately reported from the remainder of the Group's activities.

The remainder of the Group's components are managed together, with their operating results reviewed on an aggregated basis. All of the Group's revenue is generated from investment properties located in a small radius within central London. The properties are managed as a single portfolio by a portfolio management team whose responsibilities are not segregated by location or type but are managed on an asset-by-asset basis. The majority of the Group's assets are mixed-use, therefore the office, retail and any residential space is managed together. The Directors have considered the nature of the business, how the business is managed and how they review performance, and in their judgement, the Group has only two reportable segments.

Segmental analysis for the period ended 30 September 2024

Revenue for the Group's Fully Managed offices in the period to 30 September 2023 was £5.3 million (£5.6 million including share of joint ventures).

The Group capitalised interest on certain developments with specific associated borrowings at 7.3% (2023: n/a), with the remainder at the Group's weighted average cost of non-specific borrowings of 4.0% (2023: 3.75%).

7 Tax

The difference between the standard rate of tax and the effective rate of tax arises from the items set out below:

During the period, £0.2 million (2023: £nil) of deferred tax was debited directly to equity. The Group recognised a net deferred tax asset at 30 September 2024 of £nil (2023: £nil). This consists of deferred tax assets of £1.4 million (2023: £1.2 million) and deferred tax liabilities of £1.4 million (2023: £1.2 million). Deferred tax is calculated using tax rates that have been enacted or substantively enacted at the balance sheet date.

Movement in deferred tax:

In order to ensure that the Group is able to both retain its status as a REIT and to avoid financial charges being imposed, a number of tests (including a minimum distribution test) must be met by both Great Portland Estates plc and by the Group as a whole on an ongoing basis. These conditions are detailed in the Corporation Tax Act 2010.

8 Earnings per share, alternative performance measures and EPRA metrics

Adjusted earnings and net assets per share are calculated in accordance with the Best Practice Recommendations issued by the European Public Real Estate Association (EPRA). The recommendations are designed to make the financial statements of public real estate companies clearer and more comparable across Europe, enhancing the transparency and coherence of the sector. The directors consider these standard metrics to be the most appropriate method of reporting the value and performance of the business. The reconciliations between these measures and the equivalent IFRS figures are shown in the tables below.

In June 2024, the Company issued 152,320,747 new shares through a rights issue (see note 16). To reflect the rights issue, the comparative number of shares previously used to calculate the basic and diluted per share data has been restated in the below earnings and net asset value per share calculations. In accordance with IAS 33 - Earnings per share, an adjustment factor of 1.20 has been applied to the comparative number of shares based on the ratio of the Company's closing share price of 414.6 pence per share on 22 May 2024, being the day prior to the announcement of the rights issue (adjusted for the recommended final dividend for the year ended 31 March 2024) and the theoretical ex-rights price at that date of 345.4 pence per share.

Earnings per share:

EPRA Earnings per share

Net assets per share:

In accordance with EPRA, we report three NAV metrics: EPRA Net Tangible Assets (NTA), Net Reinvestment Value (NRV) and Net Disposal Value (NDV). We consider EPRA NTA to be the most relevant measure for the Group and the primary measure of net asset value alongside IFRS net asset value. Whilst there is no specific accounting guidance on how NTA metrics should be restated following a Rights Issue, we have restated the comparatives using the IAS 33 method (as set out above).

In addition, we have presented a pro forma net assets per share, which restates the 31 March 2024 balance sheet, to include the net proceeds and new shares issued as a result from the rights issue. We consider the pro forma net assets per share to be a more appropriate metric to benchmark performance over the six month period, given it is based on balance sheet values rather than share price derived metrics.

EPRA loan-to-property value and net debt

Group cash and cash equivalents includes customer rent deposits held in separate designated bank accounts of £17.6 million (2023: £17.8 million), the use of the deposits is subject to restrictions as set out in the customer's lease agreement and therefore not available for general use by the Group.

Net gearing

The book value of investment property includes £74.1 million (31 March 2024: £74.1 million) in respect of the present value of future ground rents. The market value of the portfolio (excluding these amounts) is £2,013.2 million (31 March 2024: £1,855.1 million). The total portfolio market value including joint venture properties of £483.3 million (31 March 2024: £476.1 million) (see note 10) was £2,496.5 million (31 March 2024: £2,331.2 million). At 30 September 2024, property with a carrying value of £112.5 million (31 March 2024: £107.0 million) was secured under the first mortgage debenture stock (see note 15). At 30 September 2024, one property had exchanged for sale and accordingly was classified as held for sale. The sale is anticipated to complete in January 2025.

In October 2024, the Group acquired 19/23 Wells Street, W1, for £19.0 million and November 2024 we acquired Whittington House, WC1 for £58.5 million.

Surplus/(deficit) from investment property

The Group's investment properties, including those held in joint ventures (note 10), were valued on the basis of fair value by CBRE Limited (CBRE), external valuers, as at 30 September 2024. The valuations have been prepared in accordance with the current versions of the RICS Valuation - Global Standards (incorporating the International Valuation Standards (IVS)) and the UK national supplement (the Red Book) and have been primarily derived using comparable recent market transactions on arm's length terms.

9 Investment property (continued)

The total fees, including the fixed fee for this assignment, earned by CBRE (or other companies forming part of the same group of companies within the UK) from the Group are less than 5.0% of its total UK revenues. CBRE has carried out valuation instructions, agency and professional services on behalf of the Group for in excess of 20 years.

For investment property, this approach involves applying market-derived capitalisation yields to current and market derived future income streams with appropriate adjustments for income voids arising from vacancies or rent-free periods. In the case of investment property under development, the approach applied is the 'residual method' of valuation, which is the investment method of valuation as described above with a deduction for the costs necessary to complete the development, together with an allowance for the remaining risk.

Everything else being equal, there is a positive relationship between rental values and the property valuation, such that an increase in rental values will increase the valuation of a property and a decrease in rental values will reduce the valuation of the property. Any percentage movement in rental values will translate into approximately the same percentage movement in the property valuation. However, due to the long-term nature of leases, where the passing rent is fixed and often subject to upwards only rent reviews, the impact will not be immediate and will be recognised over a number of years. The relationship between capitalisation yields and the property valuation is negative and more immediate; therefore, an increase in capitalisation yields will reduce the valuation of a property and a reduction will increase its valuation. There is a negative relationship between development costs and the property valuation, such that an increase in estimated development costs will decrease the valuation of a property under development and a decrease in estimated development costs will increase the valuation of a property under development.

An increase of 10% on the capital expenditure on the Group's three HQ development schemes and four Flex conversion schemes, which the Directors believe is a reasonable variance to budgeted cost based on industry experience, would reduce the valuation by £39.4 million (31 March 2024: £49.8 million), with a decrease of 10% increasing the valuation by £39.4 million (31 March 2024: £49.8 million).

A decrease in the capitalisation yield by 25 basis points would result in an increase in the fair value of the Group's investment property by £96.0 million (£120.7 million including a share of joint ventures; 31 March 2024: £241.4 million based on a 50 basis point movement), whilst a 25 basis point increase would reduce the fair value by £87.6 million (£110.1 million including a share of joint ventures; 31 March 2024: £200.0 million based on a 50 basis point movement). A movement of 3 basis points was shown across the portfolio over the last 6 months and a 25 basis point movement is therefore considered to be a reasonably possible change. Given there is only a marginal difference in the overall yields for office and retail and the movement in year, we feel this sensitivity to be appropriate. There are interrelationships between these inputs as they are determined by market conditions, and the valuation movement in any one period depends on the balance between them. If these inputs move in opposite directions (i.e. rental values increase and yields decrease), valuation movements can be amplified, whereas if they move in the same direction, they may offset, reducing the overall net valuation movement.

The valuation of the property portfolio reflects its fair value taking into account the market view of all relevant factors including the climate related risks associated with the properties. This includes the impact of expected regulatory changes, and we estimate that the investment required to upgrade our existing buildings to the new minimum EPC B rating by 2030 is less than £10 million (including share of joint ventures) over and above specific refurbishment and development assumptions included in the valuation.

Key inputs to the valuation (by building and location) at 31 March 2024

During the period, the Group capitalised £0.9 million (2023: £0.7 million) of employee costs in respect of its development team into investment properties under development. At 30 September 2024, the Group had capital commitments of £397.2 million (31 March 2024: £502.3 million).

10 Investment in joint ventures

Transactions during the period between the Group and its joint ventures, who are related parties, are set out below:

The joint venture balances are repayable on demand and bear interest as follows: the GHS Limited Partnership at 4.0% and the Great Ropemaker Partnership at 2.0%. In measuring expected credit losses of the balances receivable at the period end from joint ventures under IFRS 9, the ability of each joint venture to repay the loan at the reporting date if demanded by the Group is assumed to be through the sale of the investment properties held by the joint venture. Investment properties are held at fair value at each reporting date as described in note 9. Therefore, the net asset value of the joint venture is considered to be a reasonable approximation of the available assets that could be realised to recover the loan balance and the requirement to recognise expected credit losses.

10 Investment in joint ventures (continued)

Summarised balance sheets

At 30 September 2024 and 31 March 2024, the joint ventures had no external debt facilities.

The investment properties include £5.1 million (2023: £5.1 million) in respect of the present value of future ground rents, net of these amounts the market value of our share of the total joint venture properties is £483.3 million. The Group earns fee income from its joint ventures for the provision of management services. All of the above transactions are made on terms equivalent to those that prevail in arm's length transactions. At 30 September 2024, the Group's share of joint venture capital commitments was £nil million (2023: £nil million).

11 Property, plant and equipment

In January 2020, the Group entered into a commitment of up to £5.0 million to invest in Pi Labs European PropTech venture capital fund. At 30 September 2024, the Group had made net investments of £2.9 million. Launched in 2014, Pi Labs is Europe's longest standing PropTech VC and this third fund has a primary focus to invest in early stage PropTech start-ups across Europe and the UK that use technology solutions to enhance any stage of the real estate value chain. Key areas of focus for the fund include sustainability, the future of work, the future of retail, commercial real estate technologies, construction technology and smart cities. The valuation of the fund is based on the net assets of its investments therefore, given these are not readily traded, we have classified the valuation of the investments as Level 3 as defined by IFRS 13.

13 Trade and other receivables

Trade receivables consist of rent and service charge monies, which are typically due on the quarter day with no credit period. Interest is charged on trade receivables in accordance with the terms of the occupier's lease. Trade receivables are provided for based on the expected credit loss, which uses a lifetime expected loss allowance for all trade receivables based on an assessment of each individual occupier's circumstance. This assessment reviews the outstanding balances of each individual occupier and makes an assessment of the likelihood of recovery, based on an evaluation of their financial situation. Where the expected credit loss relates to revenue already recognised this has been recognised immediately in the income statement.

13 Trade and other receivables (continued)

The Directors consider that the carrying amount of trade payables approximates their fair value.

15 Interest-bearing loans and borrowings

The Group's £450 million unsecured revolving credit facility (RCF) is unsecured, attracts a floating rate based on a headline margin which was reduced to 90.0 basis points over SONIA (plus or minus 2.5 basis points subject to a number of ESG linked targets) and matures in January 2027. At 30 September 2024, the Group had £450.0 million (2023: £228.0 million) of undrawn committed credit facilities.

The Group's £250 million unsecured term loan has a headline margin of 175 basis points over SONIA. The loan has an initial three-year term which may be extended to a maximum of five years at GPE's request, subject to bank consent. The Group also has a £200 million interest rate cap to protect against any further increases in rates whilst preserving the benefit of any reductions. The interest rate cap expires in October 2025.

15 Interest-bearing loans and borrowings (continued)

In September 2024, the Group issued a sterling denominated senior unsecured sustainable £250 million bond. The bond has a term of seven years, bears interest at a rate of 5.375% and is rated Baa2 by Moody's Investor Services Ltd.

The Group had a £200 million loan facility at a headline margin of 75 basis points over SONIA, with the margin stepping up by 0.25% after six months, a further 0.25% after 12 months and a final step-up of 0.50% at 18 months. The loan was undrawn and cancelled on 30 May 2024.

The Group's £175.0 million 2.15% private placement notes 2024 were repaid on 22 May 2024.

At 30 September 2024, the Group has committed cash and undrawn credit facilities of £695.7 million (31 March 2024: £633.4 million). At 30 September 2024, properties with a carrying value of £112.5 million (31 March 2024: £107.0 million) were secured under the Group's debenture stock.

In October 2024, the Group signed a new £150 million ESG-linked unsecured revolving credit facility (RCF) at a headline margin of 90 basis points over SONIA. The facility has an initial three-year term which may be extended to a maximum of five years at GPE's request, subject to bank consent.

In November 2024, £175 million of the Group's £250 million term loan was repaid.

Fair value of financial liabilities

The fair values of the Group's cash and cash equivalents and trade payables and receivables are not materially different from those at which they are carried in the financial statements. The fair values of the Group's private placement notes and debenture stock were determined by comparing the discounted future cash flows using the contracted yields with those of the reference gilts plus the implied margins.

16 Share capital

In June 2024, the Company raised gross proceeds of £350.3 million (£335.6 million net proceeds) by issuing 152,320,747 new ordinary shares through a 3 for 5 rights issue.

At 30 September 2024, the Company had 406,188,658 ordinary shares with a nominal value of 155⁄19 pence each.

17 Head lease obligations

Head lease obligations in respect of the Group's leasehold properties are payable as follows:

The investment in the Company's own shares is held at cost and comprises 1,393,542 shares (31 March 2024: 887,159 shares) held by the Great Portland Estates plc LTIP Employee Share Trust which will vest for certain senior employees of the Group if performance conditions are met.

During the period, no shares (2023: no shares) were awarded to directors and senior employees in respect of the 2020 LTIP award and 25912 shares were awarded for the 2019 director's bonus scheme. The fair value of shares awarded and outstanding at 30 September 2024 was £12.0 million (31 March 2024: £9.8 million).

20 Cash and cash equivalents

Amounts held in respect of customer rent deposits are subject to restrictions as set out in the customers' lease agreements and therefore not available for general use by the Group.
