Welcome to the Investor presentation for the Q1 Financial Results of Heimar Real Estate Company in Iceland. Earlier today, the Board of Directors of the company approved the consolidated financial accounts, and they have now been published along with this presentation and a press release on Nasdaq OMX, as well as on the website of heimar.is. All information and a recording of this video, both in Icelandic and English, are readily available on the website and on Nasdaq OMX. We are reporting 18.1% revenue growth following significant investments, and we see that there is strong real revenue growth and solid leasing momentum in the portfolio. We see that the real growth registers at roughly 13.7%. EBITDA comes in at ISK 2.8 billion, increasing by roughly 16.5% year-on-year.
Net profit for the first quarter comes in at ISK 2.3 billion. Important note, inflation development are bringing the outlook for the year toward the upper end of the announced earning guidance that we published in our full financial year for 2025. The outlook for the year is in the upper level of the guideline that we have already published. The equity ratio at the end of Q1 remains at roughly 32%. The LTV ratio remains moderate at 61.5%. We issued a new bond series for ISK 5 billion during the quarter, and total investment in the portfolio amounted roughly ISK 2.3 billion.
We've stated to you before that we operate a clear strategy, and we see that investment in high-quality properties in core areas is the key driver of our real revenue growth. We have continued with share buyback programs, with share repurchased at a nominal value of ISK almost 50 million in the first quarter, and the total purchase of value of treasury shares could amount to approximately ISK 2 billion during the year 2026. Heimar is an attractive investment opportunity with solid fundamentals from left to right. We are a reliable and responsible investment opportunity, and you see that the EBITDA development of the company has been growing steadily from the year 2020. We operate, as I've said to you before, in core areas with a clear strategy and strong execution.
75% of our rental revenue comes from already predefined core areas within the city of Reykjavík. We have a moderate and lowering LTV ratio, which currently stands around 61%, and we are focused on sustainability and social responsibility with roughly 42% of the company's portfolio in environmentally certified assets. We see a 13.7% real growth year-on-year in the top line, and we see that EBITDA is increasing by 16.5% between years. It comes in at 69.3%, and the occupancy rate in our portfolio is roughly around 96%. As disclosed earlier, profit after tax is ISK 2.3 billion, and the fair value adjustments of investment properties that I will dive into deeper later on in the presentation comes in at ISK 4.3 billion. Return on equity is 11.7%.
Looking at our financial position, investment properties are booked at ISK 235 billion, with interest-bearing liabilities of ISK 141 billion, which gives us an LTV ratio of 61.4% and an equity ratio of 32.3%. Just a brief overview of our portfolio that comprises 97 different assets. We have an occupancy rate extremely high of 96%, 430 customers, and roughly 75% of our rental income comes from core areas. Within the portfolio, we have 390,000 sq m, the average term of our lease is around six years. As discussed before, we have roughly around 42% of our portfolio environmentally certified, and we match that with proportion of green financing, which is around 42% of our outstanding liabilities.
The four main areas that we focus on are core areas where 75% of our rental income stems from. If you look at our customer base, 12% are listed companies on stock exchanges. 31% of our revenue stems from public entities, and around 42%-43% of our buildings are environmentally certified. Diving into the finance and operations, we are reporting strong nominal and real revenue growth, with the top line growing roughly 18.1% in the quarter, resulting in an EBITDA increase of 16.5%. We see that profit for the period comes in at just shy of ISK 2.3 billion and increases by roughly 64% from Q1 last year.
On the right-hand side, you see the development of rental income, EBITDA, and the operating cost of investment properties. You see the development for the last three first quarters in 2026, 2025, and 2024. If we disaggregate the real revenue growth, you see from the bridge that has been built there, we start in Q1 2025. We see inflation, the blue one, increase above inflation, which is the real growth, and then the change in the property portfolio. If we look at this in a more decisive manner, we see that changes in the portfolio positively affect year-on-year revenue growth. We are reporting revenue growth of 7.3% on a like-for-like portfolio, and real revenue growth of 2.8% on a like-for-like portfolio.
Looking at our accounts receivable, we argue that a strong tenant mix is set to mitigate risks in our portfolio. We have a high quality tenant base with roughly 43% of our tenants either being listed companies on stock exchanges or local or municipalities and the government. You see that the receivables more than 30 days overdue are roughly ISK 220 million on the back of revenue somewhere around ISK 18 billion. It's increasing, but it's still a very low proportion of our revenue. Looking at our equity ratio and LTV ratio, equity ratio on top, you see that's been strengthening over the course of the last few quarters. I said to investors in our last presentation that the investors should not expect the equity ratio to continue to increase.
It decreases a bit, of course, due to share buybacks and dividend payments that, in this year. Also, the LTV ratio remains very healthy, registering at just north of 61% at the end of Q1 2026. The positive fair value adjustment is ISK 4.3 billion in the quarter. Inflation is the primary driver of valuation changes. Weighted average cost of capital is almost the same as it was at the year-end 2025, down by 1 basis point. As stated before, total investments in the portfolio amounted to ISK 2.3 billion in the quarter. If we look at our refinancing plan for the next few years, we can state that we have no refinancing need in 2026, and green financing comprises roughly 42% of our interest-bearing debt.
We issued a new bond series, amounting to ISK 5 billion during the quarter, and approximately 28% of interest-bearing loans are bank loans. The effective interest rate on indexed loans was 3.44% at the end of the quarter, and we expect that refinancing of bank loans maturing in 2027 is well underway and is expected to be completed in the second quarter. Looking into our shareholder base, we say we are very shareholder-focused. Intrinsic value is the benchmark for buybacks, and we say we need to look at the P/B ratio adjusted for non-interest-bearing deferred tax liability. On the right-hand side, you see the P/B, price -to- book development over the last year and a half or so.
We have, for illustrative purposes, inserted where we have had effective share buyback programs and the market value of these buyback programs. The total purchase value of treasury shares since April 2025 amounts to ISK 2.75 billion. There have been minimal changes in terms of our largest shareholders in the quarter, which is depicted on this slide. If you look at the share price in the first quarter, we're down 8.1%, and we're still one of the most actively traded share on Nasdaq Iceland, coming in in the tenth highest average daily turnover in the first quarter of 2026. Finally, our financial calendar for the year.
The next financial presentation will be at the end of August 27, and then we will meet again in November.
