GRANITE REIT ANNOUNCES 2025 THIRD QUARTER RESULTS AND A 4.4% DISTRIBUTION INCREASE COMMENCING IN DECEMBER 2025

November 5, 2025, Toronto, Ontario, Canada — Granite Real Estate Investment Trust (TSX: GRT.UN; NYSE: GRP.U) ("Granite" or the "Trust") announced today its condensed consolidated combined results for the three and nine month periods ended September 30, 2025 and a distribution increase of 4.41% effective with the December 2025 distribution.

THIRD QUARTER 2025 HIGHLIGHTS

Highlights for the three month period ended September 30, 2025 are set out below:

Financial:

•Granite's net operating income ("NOI") was $127.1 million in the third quarter of 2025 compared to $119.6 million in the prior year period, an increase of $7.5 million primarily as a result of contractual rent adjustments and consumer price index based increases, renewal and re-leasing activity, the acquisition of two income-producing properties in the United States in the second quarter of 2025, and the lease commencement of two completed expansion projects in Canada and Netherlands during 2024;

•Constant currency same property NOI - cash basis(4) increased by 5.2% for the third quarter of 2025;

•Funds from operations ("FFO")(1) was $89.9 million ($1.48 per unit) in the third quarter of 2025 compared to $85.2 million ($1.35 per unit) in the third quarter of 2024;

•Adjusted funds from operations ("AFFO")(2) was $77.0 million ($1.26 per unit) in the third quarter of 2025 compared to $76.6 million ($1.22 per unit) in the third quarter of 2024;

•During the three month period ended September 30, 2025, the Canadian dollar weakened against the Euro and the US dollar relative to the prior year period. The impact of foreign exchange on FFO and AFFO for the three month period ended September 30, 2025, relative to the same period in 2024, was favourable by $0.04 per unit for each measure;

•AFFO payout ratio(3) was 67% for the third quarter of 2025 compared to 68% in the third quarter of 2024;

•In-place occupancy as at September 30, 2025 was 96.8%, representing an increase of 100 basis points relative to in-place occupancy as at June 30, 2025. Committed occupancy as at November 5, 2025 is 97.1%;

•Net leverage ratio as at September 30, 2025 was 35%, representing an increase of 300 basis points relative to December 31, 2024. The increase was primarily driven by the classification of certain assets as held for sale, which reduced investment properties by

$370.7 million, as well as increased unsecured debt of $78.0 million, from draws on the credit facility to fund, in the short-term, unit repurchases under the normal course issuer bid ("NCIB"). If the assets held for sale were included in the fair value of investment properties, net leverage ratio would be 34%;

•Granite recognized $34.6 million in net fair value losses on investment properties in the third quarter of 2025, primarily attributable to the expansion in the discount and terminal capitalization rates at select properties in the United States and Europe due to market conditions. The value of investment properties was increased by unrealized foreign exchange gains of $156.5 million in the third quarter of 2025 primarily resulting from the relative weakening of the Canadian dollar against the Euro and the US dollar as at September 30, 2025 compared to June 30, 2025;

•Granite's net income attributable to unitholders in the third quarter of 2025 was $68.0 million in comparison to $111.6 million in the prior year period primarily due to an unfavourable change in the fair value adjustments on investment properties of $77.2 million, and a $2.2 million increase in interest expense and other financing costs, partially offset by a $26.5 million increase in income tax recovery, a $7.5 million increase in net operating income as noted above, and a $2.0 million favourable change in fair value losses on financial instruments; and

•On November 5, 2025, Granite increased its targeted annualized distribution by 4.41% to $3.55 ($0.2958 per month) per unit from $3.40 ($0.2833 per month) per unit to be effective upon the declaration of the distribution in respect of the month of December 2025 and payable in mid-January 2026.

Operations:

•As at September 30, 2025, six income producing properties located in the United States and Netherlands were classified as assets held for sale with a fair value of $370.7 million;

•During the third quarter of 2025, Granite achieved average rental rate spreads of 88% over expiring rents representing approximately 1,846,000 square feet of new leases and renewals taking effect in the quarter; and

•During the third quarter of 2025, Granite executed a lease commencing in the first quarter of 2026 for the remaining vacant unit comprising approximately 148,000 square feet at its completed phase I development in Houston, Texas for a 126 month term with a global automotive accessories manufacturer and distributor.

ENVIRONMENTAL, SOCIAL, GOVERNANCE + RESILIENCE (ESG+R)

Granite completed its sixth annual GRESB Real Estate Assessment in the third quarter of 2025. GRESB’s 2025 results were published in October 2025 and Granite ranked 1st out of 7 in the Northern America | Industrial | Listed | Tenant Controlled peer group. Granite’s overall score increased by 1 point compared to the prior year. In GRESB’s 2025 Public Disclosure Report, which evaluates the level of ESG disclosure by listed property companies and REITs, Granite was ranked 1st in the United States of America Industrial sector comprised of 10 reporting entities. Granite continues to implement strategic initiatives to enhance its ESG+R Program into 2026 and beyond.

2025 OUTLOOK

Granite is increasing its 2025 guidance and narrowing the ranges relative to estimates presented at the commencement of the year on February 26, 2025 and subsequently on August 6, 2025. Granite’s current outlook reflects lease renewals and new leasing of vacant space completed year-to-date which have increased overall NOI estimates including constant currency same property NOI – cash basis estimates. The current outlook reflects the acquisition of the Florida properties completed June 30, 2025, but does not include any assumption for potential property dispositions. In addition, the current outlook reflects year-to-date financing and NCIB activity completed in the first half of 2025, and embeds the year to date positive impact to FFO of a weaker Canadian dollar relative to the Euro and U.S. dollar. Granite’s FFO per unit forecast represents an approximate 7% to 9% increase over 2024 and the AFFO per unit forecast represents an approximate 4% to 5% increase over 2024, partially impacted by higher maintenance capital expenditures relative to the prior year.

The high and low ranges of Granite’s forecast are impacted by foreign currency exchange rate assumptions for the three-month forecast period only, between October and December 2025, which have been modified relative to guidance provided on February 26, 2025, May 7, 2025 and August 6, 2025, reflecting a weakening of the Canadian dollar relative to both the Euro and the U.S. dollar.

The table below outlines Granite’s current forecast for the year ending December 31, 2025:


Measure	Current	Previously Published
EUR:CAD exchange rate (1)	1.59 to 1.63	1.56 to 1.61
USD:CAD exchange rate (1)	1.38 to 1.41	1.35 to 1.39
FFO per unit	$5.83 to $5.90	$5.75 to $5.90
AFFO per unit	$5.03 to $5.10	$4.90 to $5.05
Maintenance capital expenditures, tenant allowances and leasing commissions impacting AFFO	no change	$40.0 million
Constant currency same property NOI - cash basis, four quarter average	5.4% to 6.2%	5.0% to 6.5%

(1) Foreign exchange rate assumptions pertain to forecast period only of the respective outlook.

Granite’s 2025 forecast assumes no incremental acquisitions and dispositions, and assumes no favourable reversals of tax provisions relating to prior years which cannot be determined at this

time. Non-GAAP performance measures are included in Granite’s 2025 forecast above (see “NON-GAAP PERFORMANCE MEASURES, RATIOS AND RECONCILIATIONS”). See also “FORWARD-LOOKING STATEMENTS”.

NON-GAAP PERFORMANCE MEASURES, RATIOS AND RECONCILIATIONS

Readers are cautioned that certain terms used in this press release such as FFO, AFFO, FFO payout ratio, AFFO payout ratio, same property NOI - cash basis, constant currency same property NOI - cash basis, total debt and net debt, net leverage ratio, and any related per unit amounts used by management to measure, compare and explain the operating results and financial performance of the Trust do not have standardized meanings prescribed under IFRS® Accounting Standards as issued by the International Accounting Standards Board (“IFRS Accounting Standards” or “GAAP”) and, therefore, should not be construed as alternatives to net income, cash provided by operating activities or any other measure calculated in

accordance with IFRS Accounting Standards. Additionally, because these terms do not have a standardized meaning prescribed by IFRS Accounting Standards, they may not be comparable to similarly titled measures presented by other publicly traded entities.

(1)FFO is a non-GAAP performance measure that is widely used by the real estate industry in evaluating the operating performance of real estate entities. Granite calculates FFO as net income attributable to unitholders excluding fair value gains (losses) on investment properties and financial instruments, gains (losses) on sale of investment properties including the associated current income tax, foreign exchange gains (losses) on certain monetary items not forming part of a net investment in a foreign operation, deferred income taxes, corporate restructuring costs and certain other items, net of non-controlling interests in such items. The Trust’s determination of FFO follows the definition prescribed by the Real Property Association of Canada (“REALPAC”) guidelines on Funds From Operations & Adjusted Funds From Operations for IFRS Accounting Standards dated January 2022 (“REALPAC Guidelines”) except for the exclusion of corporate restructuring costs. Granite considers FFO to be a meaningful supplemental measure that can be used to determine the Trust’s ability to service debt, fund capital expenditures and provide distributions to unitholders. FFO is reconciled to net income, which is the most directly comparable GAAP measure (see table below). FFO should not be construed as an alternative to net income or cash flow provided by operating activities determined in accordance with IFRS Accounting Standards.

(2)AFFO is a non-GAAP performance measure that is widely used by the real estate industry in evaluating the recurring economic earnings performance of real estate entities after considering certain costs associated with sustaining such earnings. Granite calculates AFFO as net income attributable to unitholders including all adjustments used to calculate FFO and further adjusts for actual maintenance capital expenditures that are required to sustain Granite’s productive capacity, leasing costs such as leasing commissions and tenant allowances incurred and non-cash straight-line rent and tenant incentive amortization, net of non-controlling interests in such items. The Trust's determination of AFFO follows the definition prescribed by the REALPAC Guidelines except for the exclusion of corporate restructuring costs as noted above. Granite considers AFFO to be a meaningful supplemental measure that can be used to determine the Trust’s ability to service debt, fund expansion capital expenditures, fund property development and provide distributions to unitholders after considering costs associated with sustaining operating earnings. AFFO is also reconciled to net income, which is the most directly comparable GAAP measure (see table below). AFFO should not be construed as an alternative to net income or cash flow provided by operating activities determined in accordance with IFRS Accounting Standards.

(3)The FFO and AFFO payout ratios are calculated as monthly distributions, which exclude special distributions, declared to unitholders divided by FFO and AFFO (non-GAAP performance measures), respectively, in a period. FFO payout ratio and AFFO payout ratio may exclude revenue or expenses incurred during a period that can be a source of variance between periods. The FFO payout ratio and AFFO payout ratio are supplemental measures widely used by investors in evaluating the sustainability of the Trust’s monthly distributions to unitholders.

(4)Same property NOI — cash basis refers to the NOI — cash basis (NOI excluding lease termination and close-out fees, and the non-cash impact from straight-line rent and tenant incentive amortization) for those properties owned by Granite throughout the entire current and prior year periods under comparison. Same property NOI — cash basis excludes properties that were acquired, disposed of, classified as development properties or assets held for sale during the periods under comparison. Granite believes that same property NOI — cash basis is a useful supplementary measure in understanding period-over-period organic changes in NOI — cash basis from the same stock of properties owned.

(1) The square footage relating to the NOI — cash basis represents GLA of 63.4 million square feet as at September 30, 2025. The square footage relating to the same property NOI — cash basis represents the aforementioned GLA excluding the impact from the acquisitions, dispositions, assets held for sale and developments during the relevant period.

(2) Constant currency same property NOI - cash basis is calculated by converting the comparative same property NOI - cash basis at current period average foreign exchange rates.

(5)Total debt is calculated as the sum of all current and non-current debt, the net mark to market fair value of derivatives and lease obligations. Net debt subtracts cash and cash equivalents from total debt. Granite believes that it is useful to include the derivatives and lease obligations for the purposes of monitoring the Trust’s debt levels.

(6)The net leverage ratio is calculated as net debt (a non-GAAP performance measure defined above) divided by the fair value of investment properties (excluding assets held for sale). The net leverage ratio is a non-GAAP ratio used in evaluating the Trust’s degree of financial leverage, borrowing capacity and the relative strength of its balance sheet.


As at September 30, 2025 and December 31, 2024		2025			2024
Unsecured debt, net		$	3,166.5		$	3,078.5
Derivatives, net		134.2			(25.1)

Investment properties	[B]	$	9,102.5		$	9,397.3
Net leverage ratio	[A]/[B]	35		%	32		%

(7)Overall capitalization rate is calculated as stabilized net operating income (property revenue less property expenses) divided by the fair value of the income-producing property.

(8)Annualized revenue for each period presented is calculated as the contractual base rent for the month subsequent to the quarterly reporting period multiplied by 12 months. Annualized revenue excludes revenue from properties classified as assets held for sale.

(9)Committed occupancy as at November 5, 2025.

(10)Assets held for sale are excluded from investment properties and related property metrics. Accordingly, six such assets that were held for sale as at September 30, 2025 were excluded from investment properties and related metrics as at September 30, 2025. There were no assets classified as held for sale as at December 31, 2024.
