Vonovia Gambles on Convertible Bonds as Portfolio Revaluation Looms Over Stalled Metro Markets

The German housing giant is walking a tightrope. Vonovia recently raised €850 million through a convertible bond issue, a move flagged as urgent by analysts given the near-term refinancing wall. The notes, which mature in mid-2031 and carry a conversion price just above €28, were upsized after strong demand. Investors who convert will dilute existing shareholders, but the immediate effect on the stock was less dramatic than feared: shares closed Friday at €21.52, up roughly 4 percent on the week.

That weekly gain masks a grim YTD picture. The stock has lost nearly 11 percent since January and trades a full 10 percent below its 200-day moving average of €24.35. The discount to net asset value is even starker: at €46.57 per share on an EPRA NTA basis, the equity is priced at less than half its accounting worth. Skepticism runs deep, and the next big test comes in a matter of weeks.

The ECB’s June 11 rate hike – a 25-basis-point increase to a deposit rate of 2.25 percent – landed just before Vonovia’s mid-year portfolio valuation date of June 30. With ten-year Bund yields hovering near 3.1 percent, higher discount rates will squeeze property values directly. The portfolio stood at €84.7 billion at end-Q1; any downward revision risks testing the stock’s year low of €19.53 set on June 9. A benign revaluation would be the strongest argument against revisiting that floor.

Should investors sell immediately? Or is it worth buying Vonovia?

Operational numbers, by contrast, provide a cushion. First-quarter average rent reached €8.46 per square meter, occupancy ran at 97.7 percent, and the collection rate hit 99.6 percent. Organic rental growth came in at 4.0 percent, pushing adjusted EBITDA in the lettings segment up 6.3 percent year-on-year. Management maintains its full-year adjusted EBITDA guidance of €2.95 billion to €3.05 billion. Yet higher interest costs are eating into net profits: adjusted earnings attributable to shareholders fell 7.2 percent in Q1 to €365.6 million.

The convertible bond is a direct response to the looming refinancing hump. Vonovia faces bond maturities of €1.6 billion to €2.3 billion this year alone, with the tab surging to nearly €5 billion in both 2027 and 2028. To reduce reliance on the euro market, the company has already placed paper in British pounds and Australian dollars. But the ECB’s path remains hostile: markets price a 37 percent chance of another 25-bp increase at the July meeting, and at least one more step to 2.75 percent is now expected by mid-2027.

Meanwhile, the broader German housing market shows signs of fatigue. Official data from Destatis put first-quarter price growth at just 1.4 percent nationally, and in the seven largest cities the advance slowed to a mere 0.3 percent. That directly crimps Vonovia’s portfolio, which concentrates heavily in those same urban centres. Structural supply shortages – only 207,000 apartments were completed in 2025, the lowest since 2012, with 2026 likely to repeat the figure against annual demand of 320,000 – support rents, which are expected to climb 3.0–4.5 percent this year. But that operational tailwind may not be enough to offset the headwinds from rates, dilution, and a flagging metro market as the half-year report arrives in August.
