Delivering our growth strategy

The Directors of Great Portland Estates plc announce the results for the Group for the six months ended 30 September 2025¹, with highlights including:

Toby Courtauld, Chief Executive, said: "We have delivered another period of strong operational performance across our prime central London portfolio, leasing more in the first half than in all of last year, driving up both our rents and our property values. It has been clear to us for a number of years that customers are choosing the best spaces in vibrant central London locations over the rest and this structural theme is as relevant today as ever; our leasing success and our 76% customer retention rate are a direct consequence of the premium quality of the HQ and Fully Managed spaces we create and the service offered by our award-winning customer experience team.

From here, we expect London's economy to continue outperforming the UK overall. Our prime located 1 million sq ft development and refurbishment programme is already attracting significant interest from prospective customers with more than £10m under offer at a 30% premium to ERV and will generate further valuation surpluses of up to £520 million. We will continue adding to our pipeline through acquisition, and profitably exiting completed business plans, all the while maintaining high liquidity and low leverage. We expect our growth strategy to generate attractive shareholder returns with a prospective 10%+ annualised return on equity and three-fold increase in EPRA EPS over the medium term."

Half Year Results

Our business

Our business is accompanied by graphics (see Appendix 1)

Our leasing activities

Given our leasing successes to date, we reiterate our rental growth guidance for the financial year, with portfolio-wide growth of 4.0% to 7.0%. For prime office space, our guidance is stronger still at 6.0% to 10.0%.

Key highlights year to date include:

· 43 new leases were signed during the first half (2024: 28 leases), generating annual rent of £37.6 million (our share: £35.5 million; 2024: £8.2 million), with market lettings 7.1% above March 2025 ERVs (offices; 7.2%; retail 1.3%), including:

o 25 Fully Managed leases signed, securing £19.1 million at an average £238 per sq ft, 6.7% ahead of the March 2025 Fully Managed ERV; AI customers now around 23% of Fully Managed portfolio;

o Four Ready to Fit leases signed, securing £14.2 million, 8.0% above the March 2025 ERV, including significant pre-let to CD&R at 30 Duke Street, SW1;

o Eight new retail leases signed, securing £3.3 million, 1.3% above the March 2025 ERV.

· Seven rent reviews were settled in the six months, securing £11.1 million of annual rent (our share: £8.4 million; 2024: £4.2 million), 8.5% ahead of previous passing rent;

· Total space covered by new lettings, reviews and renewals during the first half was 395,900 sq ft (2024: 171,100 sq ft);

· The Group's rent roll has increased by 12.3% to £138.3 million following a successful leasing period (not including pre-lets at 2 Aldermanbury Square, EC2 and 30 Duke Street, SW1); and

· 92% (by area) of the 65 leases with breaks or expiries in the twelve months to 30 September 2025 were retained (76%), re-let, or are under offer, leaving only 14,300 sq ft still to transact.

The table below summarises our leasing transactions in the period:

Leasing Transactions	Three months ended 30 September 2025	Six months ended 30 September 2025	Six months ended 30 September 2024
New leases and renewals completed
Number	26	43	28
GPE share of rent p.a.	£16.3 million	£35.5 million	£8.2 million
Area (sq ft)	87,900	256,300	94,900

Rent reviews settled
Number	5	7	6
GPE share of rent p.a.	£7.9 million	£8.4 million	£4.2 million
Area (sq ft)	123,500	139,600	76,200
Rent per sq ft (including retail)	£85	£79	£88

Note: Includes joint ventures at share

Notable transactions during the six months included:

· In May, we announced a substantial pre-let of the entirety of the office space (62,500 sq ft) at 30 Duke Street St James's, SW1. Leading global investment firm CD&R have signed a 15-year term without break and with rents 6.5% ahead of March 2025 ERV;

· In June, we completed the letting of the first floor (16,830 sq ft) at wells&more, W1. The letting completes a successful repositioning of the building securing an average rent on the refurbished floors (33,700 sq ft) of £102 per sq ft (12% ahead of March 2025 ERV) and increasing the rental income of the space by 55%;

· In addition to the completion and successful lettings at 141 Wardour Street, W1 (see below) there have been a further four completed deals at the premium, refurbished office spaces of SIX St Andrew Street, EC4, and 31/34 Alfred Place, WC1, securing £3.0 million in annual rent at an average £213 per sq ft, and as a result, SIX and 31/34 Alfred Place are now 74% and 82% let respectively; and

· In September, we secured a new letting of 7,500 sq ft at Kent House, W1, our largest Fully Managed unit, to Vanta, a leading AI platform in compliance automation and trust management. Vanta has taken over the space previously occupied by Synthesia Limited. Although Synthesia's departure will impact our customer retention rate for the year, the strong demand for our premium Fully Managed offering ensured the unit was re-let swiftly with only a four-week gap to allow us to refresh the space and demonstrates the continued demand for our spaces from AI customers, as at today, around 23% of our Fully Managed portfolio.

At 30 September 2025, the Group's vacancy rate (including share of joint ventures) was 6.9%, up marginally from 5.9% at 31 March 2025, due to recent completions of refurbishments. The average passing rent across our office portfolio was £104.10 per sq ft, up from £93.00 per sq ft at 31 March 2025 as we have completed more Fully Managed deals.

Since 30 September 2025:

· We have signed an additional six new leases, generating annual rent of £4.5 million (our share: £4.5 million), with market lettings 9.6% above March 2025 ERVs (offices; 8.5%; retail 18.4%); and

· We have 85,800 sq ft of space under offer which would deliver approximately £10.3 million p.a. in rent (our share: £10.3 million), with market lettings 30.9% above March 2025 ERVs.

Executive Committee Appointments

Rebecca Bradley and Simon Rowley have been appointed to the Executive Committee, as Customer Experience Director and Flex Workspaces Director respectively.

These promotions reflect both the significant contributions they have made and the strategic importance of their current responsibilities following the expanded roles they each took on two years ago. Under their leadership, they have delivered a step-change in both our performance and our operational capability in the delivery of our market-leading customer first approach and growing our Flex workspace offer, providing premium spaces and great experiences for all our customers.

Our investment activities

Since the start of the year, we have seen an uptick in activity levels in the central London investment market, with more deals trading above asking price and an increase in larger lot sizes. With our results in May, we stated that strengthening investment markets would provide greater opportunities to crystallise our returns, and as result we would be rotating towards sales. As anticipated, since 1 April, we completed two sales, totalling £292 million and made one acquisition for £18.0 million.

One Fully Managed acquisition adding to our West End cluster

In September we acquired a new long-leasehold interest in The Gable, WC1 for a total consideration of £18.0 million (£409 per sq ft on current NIA) from the City of London Corporation. The Gable is the latest building to join GPE's cluster of Fully Managed buildings in this prime part of the West End, within easy walking distance of Tottenham Court Road's Elizabeth line station.

GPE plans to substantially refurbish the 44,000 sq ft building to deliver its Fully Managed offer, providing best-in-class workspaces with high quality customer amenity, private terracing and re-configured modern retail space. Currently, the building is partially let on a short-term basis at an annual rent of £1.5 million generating a net yield of 6.4%.

Together, The Gable, the recently acquired Courtyard Building and Whittington House, and existing holdings at 31/34 Alfred Place, could create a 220,000 sq ft cluster of Grade A Fully Managed and HQ space in WC1, offering customers a wide range of exceptional spaces whilst delivering operational efficiencies for GPE.

Two accretive sales for a combined £292 million; marginally ahead of book value

In May, we sold Challenger House (also known as The Corner Hotel), E1 together with a plot of undeveloped land for £42.0 million, marginally ahead of March 2025 book value. Challenger House is a 74,000 sq ft (GIA) hotel featuring circa 180 fully en-suite guest rooms alongside a ground-floor restaurant and bar. The building adjoins The Hickman, our 74,900 sq ft (NIA), high quality, repositioned office building, with customers including New Look, Runway East and Four Communications which is being retained for income and value growth. Challenger House and The Hickman were jointly acquired in 2017 for £49.6 million.

In October, we completed the sale of 1 Newman Street, W1 to Royal London Asset Management for a headline price of £250 million, reflecting a net initial yield (NIY) of 4.48%, marginally ahead of the March 2025 book value. The freehold property sits on the northern side of Oxford Street, immediately opposite the Elizabeth line entrance on Dean Street. Redeveloped by GPE in 2021, 1 Newman Street is a BREEAM excellent, best-in-class HQ building comprising 121,300 sq ft of Grade A office and flagship retail space across basement, lower ground, ground, and seven upper floors. The building features private roof terraces on floors two and seven, along with a 3,100 sq ft communal terrace on level eight and is multi-let to nine customers generating annual rent of around £11.9 million, with a WAULT of 6.4 years to the earlier of break or expiry.

Further opportunities to come

Looking ahead, we expect market conditions to continue presenting a range of opportunities. Whilst our investment activity has rotated towards more sales, we will continue to pursue opportunities to acquire buildings that align with our Fully Managed offer in our established cluster locations or present significant HQ development upside. At the same time, we will look to crystallise value where business plans have been delivered, including some of our stabilised assets. As a result, we currently have approximately £150-£200 million of near-term sales under consideration.

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 indicate that future supply of new space in London will be severely constrained. We estimate that only 2.5 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 4.6 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 nearing completion at our fully pre-let 2 Aldermanbury Square, EC2. The new building will provide 322,600 sq ft (up from 176,000 sq ft) of best-in-class office and retail space. All of the 321,100 sq ft of office space is pre-let to Clifford Chance, who will take occupation in the first quarter of 2026. Upon completion, the scheme will transform the local environment and deliver a number of public realm and amenity improvements that will positively impact the local area. The building will feature 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 16.4%, given market yield expansion driven valuation declines to date, from the 30 September 2025 valuation the scheme is expected to deliver around £4 million of future profit.

At 30 Duke Street, St James's, SW1, the building has topped out, the stone cladding is complete and the mansard roof is under construction. Our major office-led redevelopment will provide 70,900 sq ft (up from 54,700 sq ft) of new Grade A space. During the period, all of the office space was pre-let to CD&R at rents significantly above our underwriting assumptions, making 30 Duke Street our best-performing asset in the first half of the year. Once complete, the building will offer column-free floorplates and high-specification amenities, including a wellness suite, private terraces on upper floors, and a communal roof terrace with panoramic views. We are also targeting the highest sustainability credentials, including innovative reuse of materials in its construction.

We have £44 million of costs to come and the scheme is anticipated to deliver a profit on cost of 39.5%, an ungeared IRR of 20.9% and a 7.1% development yield. Completion is anticipated in Q3 2026.

At Minerva House, SE1, our transformative refurbishment will deliver 143,000 sq ft of premium Ready to Fit office space, a 56% increase in area compared to the original building. The structural works are now complete, with the building having topped out in October. This month, our main contractor, Multiplex, takes full control of the site, and façade installation is set to begin shortly. The redesigned building will make the most of its prime river frontage, with newly added storeys enabling the creation of outdoor terraces and best-in-class amenity spaces. These enhancements will offer panoramic views across central London, elevating the occupier experience. Completion is anticipated in Q1 2027.

During the period, due to complexities discovered on site and insolvencies in the supply chain, the forecast cost of the scheme increased by £14 million. Following this increase, we anticipate the scheme will deliver a profit on cost of 15.0%, an ungeared IRR of 10.0% and a development yield of 6.9%. Occupier interest in the building is strong and we have around 40% of the space under offer.

In total, across the three on-site HQ development schemes we have committed expenditure to come of £193 million and an anticipated development surplus to come of £65 million.

Two Fully Managed refurbishments completed in period; three further schemes on site

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

In July, we completed 141 Wardour Street, W1. A beautifully restored Art Deco building, 141 Wardour offers 29,900 sq ft of newly refurbished office and retail space, with workspaces ranging from 2,300 to 4,600 sq ft across six floors. With a roof terrace offering panoramic views over Soho, the building has both excellent sustainability credentials and exceptional amenities, offering an on-site gym, secure cycle storage, and unique communal areas.

Given the quality of the building we have let the entirety of the space within two months of launch, generating £6.1 million in annual rent, £3.8 million of Net Operating Income (NOI) and at an average rent of £279 per sq ft. For further details visit https://www.141wardour.co.uk/.

In September, we completed the comprehensive refurbishment of 170 Piccadilly, W1. The Grade II listed building provides 27,800 sq ft of Fully Managed space across seven floors, with workspaces ranging from 800 sq ft to 4,500 sq ft, including a spacious communal lounge, boardroom and club space, a landscaped terrace, cycle store and showers. To date we have pre-let one floor and have strong interest across the remainder, including three units under offer. Given the premium nature of the space, together with its prestigious location, we are targeting rents in excess of £300 psf on the best space, and have good leasing interest. For further details visit https://www.170piccadilly.co.uk/.

During the period, construction works commenced at the Courtyard, WC1, on Alfred Place, a short walk from the Tottenham Court Road Elizabeth line station. The Courtyard comprises 64,100 sq ft of office and partially let retail space, with the offices under refurbishment to deliver our Fully Managed offer. The scheme will feature best-in-class workspaces, high-quality amenities, a large roof terrace, and reconfigured modern retail space. Refurbishment is anticipated to complete in summer 2027, with £60 million of capex to complete. The building is expected to generate £10.1 million in Fully Managed rent roll annually (£6.4 million NOI) plus £1.1 million from the retail space, delivering a running yield of 6.3% and an ungeared IRR of over 10%.

In September, Westminster Council granted planning permission for the high-quality refurbishment of 7/15 Gresse Street, WC1 as part of our Fully Managed offering. Located in the heart of Fitzrovia, less than 200 metres from the Elizabeth line station at Tottenham Court Road, the scheme will provide 42,800 sq ft of premium Fully Managed workspace across five floors. Our plans include the retention and refurbishment of the existing buildings together with small extensions to the rear upper floors to create practical, user-friendly floorplates and a large communal terrace. Site preparation works have commenced, with completion targeted for early 2027. The building is expected to generate £8.6 million in Fully Managed rent roll annually (NOI: £4.7 million), delivering a running yield of 6.3% and an ungeared IRR in excess of 12.5%.

At 19/23 Wells Street, W1, we are creating new amenity space in the basement and ground floors of the building to create a premium arrival experience. Works are expected to conclude this month.

These three buildings together will require around £97 million of capex to complete and will deliver annualised rent roll of £22.4 million and NOI of £12.9 million. Today, our committed Flex portfolio totals 641,900 sq ft (28.9% of our office portfolio). When combined with our HQ schemes, our six on-site schemes require capex of £290 million to complete and are expected to deliver a development surplus of £88 million, the majority which we should capture over the next 18 months.

Further four HQ schemes in the pipeline

At Whittington House, WC1, we are planning to refurbish the building to deliver 74,800 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. Camden Council resolved to grant planning permission for the high-quality refurbishment of the building in October 2025 and we will be starting on-site shortly.

At our Soho Square Estate, W1 located at the eastern end of Oxford Street and backing onto Soho Square, we have secured an amended planning permission to deliver a best-in-class HQ office building fronting onto Soho Square with flagship retail on Oxford Street, arranged over basement, lower ground, ground and eight upper floors, with multiple private terraces and a communal roof terrace. With planning secured and neighbourly agreements nearing completion, we anticipate starting enabling works later next month.

In October, Southwark Council resolved to grant planning permission for the high-quality redevelopment of St Thomas Yard, SE1. Our retrofit-first proposals, are to retain and re-use the existing 1980s building's primary structure, significantly reducing embodied carbon and waste, and add five storeys to create an 11-storey office building with balconies and extensive landscaped roof terraces. Across the site, the total net area will increase from approximately 100,000 sq ft to 184,300 sq ft. The redevelopment will retain the historic frontages to St Thomas Street and restore the listed Georgian terrace. The development is expected to commence in summer 2026, completing late 2028.

At 1 Chapel Place, W1, we are advancing plans for a major redevelopment with the opportunity to significantly increase the building's massing beyond its current 34,200 sq ft. The proposed scheme aims to deliver a best-in-class, highly sustainable headquarters in one of London's most prestigious locations. Situated in the heart of the West End, the site benefits from excellent connectivity, being just a short walk from Bond Street underground station and the Elizabeth line.

The four pipeline schemes will require capex to come of £392 million and we anticipate they will deliver a development surplus of around £91 million.

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 £3,070.2 million as at 30 September 2025 (31 March 2025: £2,869.3 million), reflecting a valuation increase of 1.5% on a like-for-like basis since 31 March 2025. At 30 September 2025, the wholly-owned portfolio was valued at £2,545.7 million (31 March 2025: £2,368.5 million) and the Group had three active joint ventures which owned properties valued at £524.5 million (our share) (31 March 2025: £500.8 million) by CBRE. At 30 September 2025, 72% of our portfolio was located in the West End.

Values up 1.5%

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

· Our Fully Managed portfolio increased by 1.8% in the six months on a like-for-like basis with our five Flex refurbishment projects, including two that completed in the period, up 2.3%, largely due to rental value increases across our prime spaces;

· 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, our rental values increased by 2.6% on a like-for-like basis, with our office portfolio up by 2.7% and our prime offices up even higher by 3.3%. ERVs in our retail portfolio increased by 1.9%;

· Portfolio management - a strong six months, 50 new leases, rent reviews and renewals were completed, securing £43.9 million (our share) of annual income, supporting the valuation. At 30 September 2025, the portfolio was 10.0% reversionary;

· Developments - the valuation of our committed development properties increased by 6.1% on a like-for-like basis to £523.0 million during the period; and

· A small upward movement in yields on a like-for-like basis (office +2 basis point; retail +6 basis points). At 30 September 2025, the portfolio true equivalent yield was 5.5% (West End: 5.3%; Rest of central London: 6.0%) and reversionary yield was 6.7%.

Including rent from leases currently in rent free periods, the topped-up initial yield of the investment portfolio at 30 September 2025 was 4.1%, 30 basis points higher than the start of the financial year.

Whilst the overall valuation increased by 1.5% 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 (+2.9%) performed better than our rest of London portfolio (-1.9%) largely due to the stronger performance of our West End development and Fully Managed refurbishment portfolio;

· Our Fully Managed properties increased in value by 1.8%, of which our five Fully Managed refurbishments increased by 2.3% outperforming the Group's wider office space which increased by 1.8% in value, whilst our retail space increased in value by 0.4% resulting from an overall softening in retail yields; and

· newer, higher quality buildings outperformed older assets, with those assets with a capital value per sq ft in excess of £1,000 per sq ft, increased in value by 3.5% compared to those with a capital value per sq ft of less than £1,000 per sq ft which reduced by 2.4%.

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 increased uncertainty ahead of the UK budget in late November and the associated impact on business confidence, our property capital value indicators have weakened marginally from those we reported in May. Despite ongoing uncertainty, investment market volumes are growing, though they remain below historical norms. Liquidity is improving for larger lot sizes, as demonstrated by our sale of 1 Newman Street, W1 after the period end.

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 2026 at between 4.0% and 7.0%, prime offices 6.0% to 10.0%.

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.

EPRA NTA up 2.0% to 504 pence per share

IFRS NAV per share and EPRA NTA per share at 30 September 2025 were 504 pence, an increase of ten pence over the last six months. The main drivers were:

· The increase of 11 pence per share arising from the revaluation of the property portfolio;

· EPRA earnings for the period of 4 pence per share increased NTA; and

· The final dividend of 5 pence per share reduced NTA.

The EPRA NTA increase of 2.0% combined with the payment of last year's final dividend of £20.2 million (or 5.0 pence per share), delivered a total accounting return for the six months to 30 September 2025 of +3.0% (2024: +1.6%).

At 30 September 2025, the Group's net assets were £2,041.4 million, up from £2,000.7 million at 31 March 2025, with the increase largely attributable to the increase in the property valuation. EPRA NDV per share increased marginally to 514 pence at 30 September 2025, compared to 506 pence at 31 March 2025 (up 1.6%).

Earnings up, in line with expectations and our portfolio activities

Revenue from our wholly-owned properties increased from £44.9 million to £54.6 million. Net rental income (including the spreading of lease incentives) increased to £35.0 million compared to £31.5 million for the period to September 2024, as we have had significant leasing success at our four Fully Managed refurbishment schemes which have completed in the last twelve months. Accordingly, Fully Managed services income also rose significantly from £4.7 million to £10.3 million as we continued to complete and let these well-timed refurbishments. Service charge income was broadly flat at £7.6 million.

Adjusting for acquisitions, disposals and transfers to and from the development programme, like-for-like rental income (including from joint venture properties) increased by 5.0% on the prior period.

Cost of sales increased from £16.8 million to £21.9 million for the period to 30 September 2025, due to increased Fully Managed services as we continue to convert space to our Fully Managed offer.

Administration costs were £20.8 million, an increase of £1.3 million on the prior year with the increase primarily driven by investment in an IT transformation project to replace the Group's finance and property management system, together with inflationary increases in employee salaries.

EPRA earnings from joint ventures (excluding fair value movements) were £5.2 million, up £1.5 million on the prior year. This increase was largely driven by an insurance payout within the GHS Partnership, compensating for rent loss and delays to works caused by the pandemic. Additionally, a further insolvency settlement at Mount Royal relating to the Arcadia administration contributed to the uplift. In total, our joint ventures delivered a IFRS profit before tax of £9.5 million (2024: £6.7 million).

Gross interest on the Group's debt facilities totalled £22.8 million, an increase of £5.9 million compared to the prior period. This rise was primarily driven by a combination of higher average drawn debt levels and increased underlying interest rates. Additionally, the issuance of our £250 million inaugural sustainable sterling bond contributed to the increase, with proceeds used to fund recent acquisitions and capital expenditure across development projects and Flex refurbishments. Given the Group's expanded development and refurbishment activity, interest capitalised during the period rose to £18.0 million (2024: £11.1 million). As a result, net finance costs (including interest receivable) were £3.6 million, representing a £0.3 million reduction from the prior period.

EPRA earnings were £15.7 million, 84.7% higher than for the same period last year. Revaluation gains together with EPRA earnings resulted in an IFRS profit after tax of £58.9 million (2024: £29.7 million). The diluted profit per share for the period was 14.5 pence, compared to 8.1 pence per share for 2024. Diluted EPRA earnings per share was 3.9 pence (2024: 2.3 pence) in line with market consensus.

Results of joint ventures

The Group's net investment in joint ventures was £528.6 million, an increase from £507.2 million at 31 March 2025, largely due to an increase of 0.8% 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 £7.9 million, up from £7.7 million last year primarily largely attributable to our leasing activities at Mount Royal, W1, in our Great Victoria Partnership. The underlying joint venture profits are stated after charging £1.3 million of GPE management fees, up on the previous year due to the development manager fee in our GRP joint venture (2024: £1.0 million).

Overall, our three active joint ventures represent an important proportion of the Group's business. At 30 September 2025, joint ventures represented 17.1% of the portfolio valuation, 25.9% of net assets and 17.1% of rent roll (31 March 2025: 17.5%, 25.4% and 18.6% respectively).

Strong liquidity and low pro forma EPRA LTV of 28.2%

The Group's consolidated net debt excluding restricted cash, increased to £998.7 million at 30 September 2025, compared to £835.7 million at 31 March 2025. The increase was largely due to development capital expenditure across the Group of around £178 million in the six months and the acquisition of the Gable, WC1 offset by the sale of Challenger House, E1. Group net gearing increased to 49.0% at 30 September 2025 (31 March 2025: 41.9%). Including cash balances in the joint ventures, total net debt, excluding customer deposits, was £984.9 million (31 March 2025: £820.9 million) equivalent to an EPRA loan to value (LTV) of 34.0% (31 March 2025: 30.8%).

The Group is operating with substantial headroom over its debt covenants. At 30 September 2025, property values would have to fall by around 35% before covenant breach, or 46% following the sale of 1 Newman Street, W1. 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 15.5 times (covenant: 1.35 times).

The Group's weighted average cost of debt, including fees, for the period was 5.0% (year to 31 March 2025: 5.2%). The weighted average interest rate (excluding fees) at the period end was 4.6%, down from 4.7% at 31 March 2025, due to a lower outstanding average balance on the Group's term loan.

At 30 September 2025, 72% of the Group's total debt was at fixed or hedged rates (31 March 2025: 85%) and our weighted average drawn debt maturity was 4.2 years (31 March 2025: 5.2 years).

In September, Moody's Ratings confirmed that GPE's Baa2 long-term issuer rating and stable outlook remain unchanged following periodic review. This outcome reflects GPE's strong balance sheet, market positioning and resilient business strategy.

In October 2025, we completed the sale of 1 Newman Street, W1 for a headline price of £250 million. In the first instance the proceeds from the sale were used to pay down amounts drawn on the Group's RCF facilities.

Also in October, we signed a new £525 million ESG-linked unsecured revolving credit facility (RCF) with a group of four existing relationship banks. The facility has a headline margin of 105 basis points over SONIA, with an initial five-year term, which may be extended to a maximum of seven years at GPE's request, subject to bank consent. The facility incorporates our ESG KPI-linked margin adjustments and standard unsecured financial covenants, consistent with our existing bank arrangements.

The new RCF replaces the Group's existing £450 million facility and will be available for general corporate purposes; this included the prepayment of its £75 million term loan in October 2025, which had a headline margin of 175 basis points over SONIA.

In addition, GPE has exercised the first extension option on its existing £150 million ESG-linked revolving credit facility, extending its maturity to October 2028. The Group's total bank facilities remain unchanged at £675 million. These refinancing activities have increased the Group's weighted average debt maturity by approximately two years on a fully drawn basis.

In October, following the sale of 1 Newman Street, W1 and the above refinancings, the Group's pro forma cash and undrawn credit facilities has increased to in excess of £462 million, our LTV has reduced to 28.2% and our weighted average debt maturity extends to around 5.9 years.

Taxation

The current tax credit for the half year was £1.6 million (2024: £nil) due to a prior period adjustment in relation to the operation of the REIT interest cover test (see below). The deferred tax credit for the period was £0.1 million (2024: £0.2 million charge). The effective tax rate on EPRA earnings was -11.4% (2024: 0%). The majority of the Group's income is tax-free as a result of its REIT status, and 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.

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.

If our REIT interest cover is below 1.25x in any year, we are subject to corporation tax on the shortfall. We originally calculated our REIT interest cover for the year ended 31 March 2025 to be below 1.25x and accrued a resulting tax charge of £1.6 million. During the period, HMRC issued updated guidance on the REIT interest cover calculation methodology and we recalculated our cover in accordance with this guidance. This gave rise to cover above 1.25x and the reversal of the £1.6 million prior year tax charge.

Dividends

The Board has declared an interim ordinary dividend of 2.9 pence per share (2024: 2.9 pence) which will be paid on 7 January 2026. 1.5 pence of this interim dividend will be a REIT Property Income Distribution (PID) in respect of the Group's tax-exempt property rental business.

Outlook

Looking ahead, we anticipate continued growth in property values and EPRA NTA through the second half of the financial year and beyond, supported by our supportive market outlook and active business plans. EPRA EPS for the second half of the year is expected to be broadly in line with first, with meaningful upside over the medium term as we unlock our organic rental growth potential. This is expected to drive a three-fold increase in EPRA EPS, supporting our progressive dividend policy. Our disciplined approach to capital management and commitment to maintaining a through-the-cycle LTV range remain unchanged. We also expect our return on equity for the current financial year to at least match that of financial year 2025, as GPE continues to progress towards delivering annual returns on equity of over 10%, excluding any benefit from potential yield compression.

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 82 to 93 of the 2025 Annual Report with no material changes:

Failure to meet customer needs	Failure to profitably deliver the development and/or refurbishment programme
Climate change and decarbonisation	People
London attractiveness	Health and safety
Adverse macro-economic conditions	Cyber security and IT infrastructure failure
Poor capital allocation decisions and/or misreading market conditions	Failure to profitably deliver the Flex Strategy

The Board and Executive Committee continue to monitor the potential risks and impacts presented by the volatile economic backdrop and ongoing geo-political tensions. The details of the UK Government's Autumn Budget, scheduled to be announced on 26 November 2025, remain uncertain and the Group will be carefully considering the potential impacts of revised fiscal policies for the UK economy, London's attractiveness and the Group's operations.

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.

Condensed notes forming part of the half year results

1 Basis of preparation

The condensed financial statements for the six months ended 30 September 2025 are unaudited and do not constitute statutory accounts within the meaning of section 434 of the Companies Act 2006. Statutory accounts for the year ended 31 March 2025, which were prepared in accordance with UK adopted International Accounting Standards, were approved by the Directors on 22 May 2025 and have 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. Management is currently assessing the detailed implications of applying the new standard on the group's consolidated financial statements.

There were no new or revised IFRSs, amendments or interpretations in issue but not yet effective that are potentially material for the Group and which have not yet been applied.

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 2025, with particular focus on the impact of 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 severe but plausible downside scenario which included the following key assumptions:

- a 17.1% decline in the valuation of the property portfolio from 30 September 2025; 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 in October 2025 the recent repayment of the £75m Term Loan and the refinancing of the £450m RCF facility into a new £525m RCF facility;

- is operating with significant headroom above its Group debt financing covenants;

- property values would have to fall by a further 16% before breach (or around 46% from 30 September 2025 values following the sale of 1 Newman Street, W1);

- the Group does not project any breaches of its interest cover ratio, with minimum coverage of 4.50x (vs 1.35x covenant) throughout the going concern period; and

- has no debt maturities other than set out above.

1 Basis of preparation (continued)

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 2025.

2 Segmental analysis

IFRS 8 Operating Segments requires the identification of operating segments based on internal financial reports detailing components of the Group regularly reviewed by the chief operating decision makers (the Group's Executive Committee) in order to allocate resources to the segments and to assess their performance.

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.

The Executive Committee reviews the performance of its Fully Managed offer based on gross revenue (including Fully Managed services income) net of cost of sales on a proportionally consolidated basis (including the Group's joint ventures at share). Total assets and liabilities are not monitored by segment.

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

Year to 31 March 2025 £m		Six months to 30 September 2025 £m	Six months to 30 September 2024 £m

1.8	Tax (credit)/charge for the period	(1.7)	0.2

During the period, £0.1 million (2024: £0.2 million credited) of deferred tax was debited directly to equity. The Group recognised a net deferred tax asset at 30 September 2025 of £nil (2024: £nil). This consists of deferred tax assets of £1.5 million (2024: £1.4 million) and deferred tax liabilities of £1.5 million (2024: £1.4 million). Deferred tax is calculated using tax rates that have been enacted or substantively enacted at the balance sheet date. During the period, HMRC issued updated guidance on the REIT interest cover calculation methodology and we recalculated our cover in accordance with this guidance. This gave rise to cover above 1.25x and the reversal of the £1.6 million prior year tax charge.

The Group has not recognised further deferred tax assets in respect of gross temporary differences arising from the following items, because it is uncertain whether future taxable profits will arise against which these assets can be utilised:

31 March 2025 £m		30 September 2025 £m	30 September 2024 £m

7.8	Share-based payments	6.0	7.2
1.5	Other	1.4	1.4
41.7		43.4	37.1

As a REIT, the majority of rental profits and chargeable gains from the Group's property rental business are exempt from UK corporation tax. The Group is otherwise subject to corporation tax. In particular, 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.

7 Tax (continued)

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 EPRA metrics, and the other metrics provided, 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. The directors applied the EPRA Best Practices Recommendations September 2024 from the accounting period ended 31 March 2025.

The book value of investment property includes £90.8 million (31 March 2025: £87.0 million) in respect of the present value of future ground rents. The market value of the portfolio (excluding these amounts) is £2,545.7 million (31 March 2025: £2,368.5 million). The total portfolio market value including joint venture properties of £524.5 million (31 March 2025: £500.8 million) (see note 10) was £3,070.2 million (31 March 2025: £2,869.3 million). At 30 September 2025, property with a carrying value of £117.8 million (31 March 2025: £114.8 million) was secured under the first mortgage debenture stock (see note 14). The opening book value of investment property has been restated by £25.8 million to correct the classification of a prior year acquisition from freehold to leasehold. At 30 September 2025, one property had exchanged for sale and accordingly was classified as held for sale.

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. In accordance with the updated RICS UK supplement of its 'Red Book', which introduces a mandatory rotation cycle for its valuers, CBRE will rotate off following their final valuation of the portfolio at 31 March 2026. A process is underway to select their successor.

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.

Real estate valuations are complex and derived using comparable market transactions which are not publicly available and involve an element of judgement. Therefore, we have classified the valuation of the property portfolio as Level 3 as defined by IFRS 13; this is in line with EPRA guidance. There were no transfers between levels during the year. Inputs to the valuation, including capitalisation yields (typically the true equivalent yield) and rental values, are defined as 'unobservable' as defined by IFRS 13.

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 Fully Managed conversion schemes, which the Directors believe is a reasonable variance to budgeted cost based on industry experience, would reduce the valuation by £30.7 million (31 March 2025: £35.7 million), with a decrease of 10% increasing the valuation by £30.7 million (31 March 2025: £35.7 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 £119.8 million (£146.2 million including a share of joint ventures) compared to a £112.1 million based on a 25 basis point movement at 31 March 2025. A 25 basis point increase would reduce the fair value by £109.5 million (£133.5 million including a share of joint ventures) compared to a £102.4 million based on a 25 basis point movement at 31 March 2025. A movement of 15 basis points was shown across the portfolio over the last 12 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.

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.

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

Year to 31 March 2025 £m		Six months to 30 September 2025 £m	Six months to 30 September 2024 £m

5.7	Interest on balances with partners (see note 5)	2.8	2.9
-	Distributions	-	-
2.5	Joint venture fees paid	1.3	1.0

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.

At 30 September 2025 and 31 March 2025, the joint ventures had no external debt facilities.

The investment properties include £5.1 million (2024: £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 £524.5 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 2025, the Group's share of joint venture capital commitments was £17.1 million (2024: £nil million).

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 2025, the Group had made net investments of £3.7 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.

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.

As at 30 September 2025, the Group had £195.0 million of undrawn committed credit facilities (31 March 2025: £343.0 million), and total committed cash and undrawn facilities of £212.0 million (31 March 2025: £361.2 million).

The Group's £450 million unsecured revolving credit facility (RCF) which would have matured in January 2027, carried a floating rate of SONIA plus a headline margin of 90 basis points, adjustable by ±2.5 basis points subject to ESG-linked targets. This facility was replaced in October 2025 by a new £525 million ESG-linked unsecured RCF with a headline margin of 105 basis points over SONIA, also subject to ESG performance adjustments. The new facility has an initial five-year term, extendable to seven years at the Group's request and subject to lender consent.

In addition, the Group has a separate £150 million ESG-linked RCF with a headline margin of 90 basis points over SONIA. This facility was extended by one year in October 2025, now maturing in October 2028, and may be extended by a further year, subject to bank lender consent.

The Group's £75 million unsecured term loan, which had a margin of 175 basis points over SONIA and was due to mature in September 2026, was repaid in full in October 2025. The £200 million interest rate cap, designed to mitigate rising rates while retaining the benefit of any reductions, also expired in October 2025.

At 30 September 2025, properties with a carrying value of £117.8 million (31 March 2025: £114.8 million) were secured under the Group's debenture stock.

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.

Independent review report to Great Portland Estates plc

Report on the condensed consolidated interim financial statements

Our conclusion

We have reviewed Great Portland Estates plc's condensed consolidated interim financial statements (the "interim financial statements") in the Half Year Results of Great Portland Estates plc for the 6 month period ended 30 September 2025 (the "period").

Based on our review, nothing has come to our attention that causes us to believe that the interim financial statements are not prepared, in all material respects, in accordance with UK adopted International Accounting Standard 34, 'Interim Financial Reporting' and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority. The interim financial statements comprise:

· the Condensed group balance sheet as at 30 September 2025;

· the Condensed group income statement and Condensed group statement of comprehensive income for the period then ended;

· the Condensed group statement of cash flows for the period then ended;

· the Condensed group statement of changes in equity for the period then ended; and

· the explanatory notes to the interim financial statements.

The interim financial statements included in the Half Year Results of Great Portland Estates plc have been prepared in accordance with UK adopted International Accounting Standard 34, 'Interim Financial Reporting' and the Disclosure Guidance and Transparency Rules sourcebook 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 enquiries, 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.

We have read the other information contained in the Half Year Results and considered whether it contains any apparent misstatements or material inconsistencies with the information in the interim financial statements.

Conclusions 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 group to cease to continue as a going concern.
