Thank you, Caroline. So let's start with our financial performance of the full year 2024, starting on page two. Our total revenue grew significantly in 2024 versus 2023 due to the high performance from our same stores in all markets, combined with the acquisitions realized during the course of the year in the U.K. with the Lok'nStore and Germany with Pickens and Prime Portfolio. Therefore, we have been able to deliver over the guidance a growth of 13% for the full year, with an acceleration in Q4 2024. Our revenue growth of 4.8% for our same store pool has been driven by a significant increase of the in-place rent in all markets of 5.2%. And at the same time, the occupancy reached almost 90% over the year. This great performance of positive growth, around 5% for six consecutive quarters, is really different than our peers.
As you can see on the next slide, page three, the graphic shows our capacity of maintaining high occupancy with a high revenue growth of our same store pool. Moving on page four, let's go through the other key items of our P&L. The net operating income, so-called NOI, grew at almost the same pace than our revenue, with 12.2% for the year 2024 versus 2023. This great achievement has been delivered with our same store pool margin increased of 0.4%, reflecting the scalability of our platform and the impact of our digitalization. The underlying EBITDA got the full benefit of our margin growth, with a + 12.2% over the full year. The amount of interest expenses increased significantly to EUR 30 million, driven by the additional debt to finance our major acquisition in the U.K.
The effective tax rate is in line with our Outlook 2024 at circa 17% of our adjusted EPRA earnings before tax. So despite these additional interest expenses and taxes, we've been able to grow our adjusted EPRA earnings by 5%, reaching more than EUR 167 million. Regarding the adjusted EPRA earning per share, and after the dilution impact from the equity raise we did in November 2023, plus the Scrip dividend, we stand at EUR 1.71 per share, which is 3% less than 2023. Turning to page five for our prospects for growth in footprint with our secured pipeline. This year, 2024, has been marked by the new secured capacity of square meters that have been added for the years 2024, 2025, and 2026. The team delivered a 30% increase in size of more than 400,000 sqm with EUR 1.2 billion of direct project costs for these three years.
It means that this secured pipeline will deliver at maturity an extra EUR 100 million of NOI based on our hurdle rate of 8%-9% return. Moving to page six, you will see on this graphic the breakdown per year with the relative importance of the pipeline versus our total size at the end of 2023. The major additional surface will come from Germany, as we shared in September last year during the German deep dive session that we organized during the EPRA conference in Berlin. The U.K. will benefit from the Lok'nStore pipeline, and the Netherlands will continue to grow at a good pace. Paris Centre will experience new redevelopments of underground car parks from Indigo Group, the European leader of this industry. Now, let's have a look at our balance sheet on page seven.
Our financial structure is designed to fund our growth ambitions, and the year 2024 has demonstrated this. We started with the first self-storage company in Europe being granted an investment grade from S&P of BBB+ with a stable outlook. Then we proposed for the first time an optional scrip dividend that was picked by more than 80% of our register. Then we issued our first bond of EUR 500 million in October with a fantastic performance of a fixed coupon of 3.625% for 10 years maturity, securing our long-term financing. As a result, we are in line with our guidance of leverage with an LTV of 23.3% and a net debt to EBITDA of 6.2x with a cash position of more than EUR 140 million, and now I will turn to Thomas.
Thank you, Marc. I will now walk you through our financial performance on page eight, starting with an all-stores view. The final quarter of the year was marked by strong momentum across our key markets, reflecting both organic growth and the impact of our recent acquisitions. All-store revenue increased by 19.3% in Q4. This growth was largely delivered by strong performance in the U.K. and Germany, where revenue increased by 47.3% and 43.7%, respectively. We also see a double-digit increase in the Netherlands, and altogether resulting in an NOI growth of 17.8%. Let's now focus on our same store basis. Q4 revenue grew by 5.2%, supported by a 5.1% increase in in-place rents, underscoring our continued ability to manage our pricing efficiently while maintaining high occupancy levels at 89.9%, showing stable customer demand across markets.
Same store NOI margins improved by 0.6 percentage points, reaching 70.8% as our efficiency initiatives, digitalization effort, and disciplined cost management offset ongoing inflationary pressures. One of the important topics this quarter was the relation between growing our network and related financing costs. With higher interest expenses linked to our recent acquisitions and expansion activities, we saw an increase in net financial cost. At the end, we kept adjusted EPRA earnings stable at EUR 43.9 million for the quarter. These Q4 results highlight the strengths of our operational execution, the benefits of our ongoing expansion, and our ability to drive growth in a disciplined and sustainable manner. Moving on to the next slide. As you will remember, our acquisition of Lok'nStore in August 2024 marked a significant milestone in our U.K. growth strategy, doubling our presence in the market with 28 acquired stores.
The integration of this portfolio has been very smooth, with operational processes fully aligned just two days after closing. Since acquisition, we have already made meaningful progress in driving occupancy, increasing it from 67% at acquisition date to 72% by December 2024. This puts us on track to reach our target of 90% occupancy by December 2026. Additionally, we are seeing a slightly stronger-than-expected performance from an NOI perspective due to rate increases to existing customers and effective cost management. This, combined with better long-term financing conditions, means that the acquisition is earnings-neutral in 2024 and accretive from 2025 onwards, both earlier than expected. Looking ahead to 2025 on page 10, we expect another year of strong performance supported by significant network expansion, showing our continued confidence in our operating model.
We plan to invest in our network expansion with around 90,000 sqm in 2025 and an estimated EUR 200 million in capital investments. Overall, we anticipate revenue and NOI to grow by approximately 11% across all stores. Our underlying EBITDA margin is assumed to improve by 0.5 percentage points, reflecting our ongoing efficiency gains and digitalization efforts. Interest expenses are expected to increase to around EUR 50 million as a result of the long-term financing of our investments. We currently estimate that our effective tax rate on adjusted EPRA earnings will move to approximately 18.5%. For shareholders, our dividends remain stable at EUR 1.17 per share with an optional Scrip dividend.
On page 11, we provide our medium-term guidance. Looking beyond 2025, our medium-term growth expectation remains strong. As 2026 is having slightly different dynamics due to what we already know now, we will provide some specific guidance for that year.
We expect all-store revenue and NOI growth of around 8% per year. In 2026, underlying EBITDA growth is likely to be mid-single digit, reflecting the impact of new store openings before returning to a higher trajectory in subsequent years, which we currently estimate to be double-digit per annum. Our effective tax rate is expected to stabilize at around 19%. Portfolio expansion remains a priority, with 125,000 sqm in new storage capacity planned in 2026 and estimated EUR 320 million in investment. Beyond that year, we expect to continue expanding at a rate of approximately 90,000 sqm per year, with annual investment of around EUR 200 million. Financial discipline remains central to our strategy. Our LTV target of 25% allows for short to mid-term flexibility of up to 35%.
Importantly, we remain on track to bring our net debt-to-EBITDA ratio back to below five times by 2028, demonstrating our commitment to the BBB+ rating. Our dividend policy remains stable, with a targeted payout of EUR 1.17 per share annually, and we expect to continue to offer an optional scrip dividend. Let's round up with a brief look at our full year performance on page 12. We ended 2024 with total real estate operating revenue increasing 12.9% to EUR 406.5 million. The growth was across markets and, as mentioned, particularly by the expansion in the U.K. and Germany and continued pricing strength across our portfolio. Net income from real estate operations grew 12% to EUR 267.6 million, reflecting both the revenue gains and effective cost management, offsetting strong cost pressures on several cost lines. Underlying EBITDA remains strong, with an increase of 12.2% versus prior year.
Despite the net interest expense increase to EUR 30.2 million, reflecting the financing for our major acquisitions and development project, adjusted EPRA earnings grew by 5% to EUR 167.4 million. After the dilutionary impact of the November 2023 equity raise and first scrip dividend offered in H2 of 2024, which together added 8.2% of new shares, adjusted EPRA earnings per share stand at EUR 1.71, only 3% below prior year. On page 13, we are looking at the performance of our various markets. Same store revenue grew 4.8% in 2024, with a 5.2% increase in in-place rent as a key driver. Occupancy remained strong, averaging 89.8% for the year, with some minor fluctuation across markets. The Netherlands and Germany were the standout performers, followed by Belgium and Denmark, both delivering solid growth. We are particularly satisfied with the industry-leading performance in the UK and the accelerating recovery in Sweden.
I conclude my commentary with a look at our balance sheet on slide 14. Shurgard's financial position remains solid, providing a strong foundation for continued growth. We have a well-diversified financing mix with a fully unencumbered asset base of EUR 6.2 billion. We are the first European self-storage operator to receive an investment-grade BBB+ rating from S&P. Our entrance to the public debt market with our EUR 500 million bond issuance was very well perceived by the market and provides long-term financial security. With net debt-to-EBITDA at 6.2% and LTV at 23.3%, we remain well within our target leverage range and confirm our commitment to the BBB+ rating. Finally, our cash reserves of EUR142.6 million, undrawn bank facilities, and the RCF provide additional liquidity, giving us ample capacity to fund future investment. With that, I will now hand back to Marc.
Thank you, Thomas, and let's go through the conclusion. Before wrapping up this exceptional year, I would like to thank our teams for their involvement and energy, and our Board of Directors for its support. 2024 has seen the full alignment of Shurgard presence, and I mean by this, first, an excellence in the operational execution, second, a massive growth acceleration, thirdly, a very significant future secured pipeline, and last but not least, a strong balance sheet. With that, I will now hand it back to Caroline.
