Summary
- DayOne has filed a Form F-1 for a proposed Nasdaq listing under the ticker DODC.
- Revenue for the first half of 2026 rose to $512m while the operator reported a $77.2m net loss.
- The filing turns last month’s reported IPO timetable into a formal transaction as DayOne continues expansion in Finland and Spain.
DayOne Data Centers has filed a registration statement for a proposed US initial public offering, converting last month’s reported listing timetable into a formal transaction while disclosing faster revenue growth and the capital demands behind its international expansion.
The Singapore-headquartered operator has applied to list American depositary shares on the Nasdaq Global Select Market under the ticker DODC. The number of shares and price range have not yet been set, so reported figures suggesting an offering of up to $5bn at a valuation of about $20bn remain market expectations rather than confirmed terms.
Reuters reports that DayOne generated $512m of revenue in the first half of 2026, up from $151.5m in the same period of 2025. Its net loss widened to $77.2m from $12.6m, showing how rapid capacity growth can increase revenue while development and operating costs continue to weigh on profitability.
The filing is a material update to DataCentral’s 28 September report, when DayOne was expected to make its SEC filing public in mid-October and potentially list in November. The registration statement means the process has advanced sooner than that reported timetable, although completion still depends on the offering becoming effective and shares being priced and sold.
Bookings and operating capacity remain different measures
DayOne’s growth has been accompanied by a large contracted development programme, but bookings and operating capacity describe different stages of that infrastructure. A booking represents customer demand committed for delivery, while a live facility has already passed through construction, commissioning and the power and network work needed to host production workloads.
That distinction is central to the investment case because DayOne’s expansion spans several countries and long build programmes. The company operates across Asia-Pacific and Europe, with European developments in Finland and Spain. Its Finnish platform includes Lahti and Kouvola, where DayOne advertises a combined 281MW of capacity, alongside additional early-stage plans elsewhere in the country.
DayOne closed a $4.5bn Series C equity financing in June and said at that point that it had secured more than 1.5GW of bookings across Asia-Pacific and Europe. Those customer commitments strengthen visibility over future demand, but fulfilling them still requires the corresponding physical capacity to be connected, built and commissioned on schedule.
Land, grid rights and other secured development resources can support later expansion without yet producing the same revenue as operating halls. Public investors will therefore need to distinguish the size of DayOne’s pipeline from the portion that is already in service and contributing to current results.
Public markets will scrutinise the build programme
Data centres consume substantial capital before the first customer server is installed. Sites need grid connections or other power infrastructure, substations, electrical distribution, standby systems, cooling plant, buildings and network routes, while some of the equipment must be ordered well before commissioning because of long manufacturing lead times.
That creates a timing gap between signing customer demand and receiving the full revenue from the corresponding facility. Strong booking growth can therefore improve visibility while also increasing the amount of capital that must be deployed before the contracted capacity is live.
The IPO would add public equity to DayOne’s existing private financing options. It would also expose the company to more regular scrutiny of utilisation, construction commitments, customer concentration, debt and returns on invested capital as individual campuses move from secured land to operation.
European projects form only part of the portfolio, but they illustrate the same execution problem. Finland offers large development opportunities and a relatively low-carbon electricity system, while Spain has attracted extensive data centre investment around several power and connectivity hubs. In both countries, the commercial value of a planned campus still depends on securing the required connection and delivering commissioned halls to customer dates.
Morgan Stanley, J.P. Morgan, BofA Securities and Citigroup are acting as underwriters. DayOne’s announcement confirms that the registration statement has been filed but that the number of depositary shares and proposed price range remain undetermined.
The formal filing therefore advances the financing process without completing it. The more durable measure of the company’s growth will be how its expanding bookings translate into operating megawatts and revenue-producing facilities, particularly in newer European markets where much of the capacity is still being built.
DayOne’s revenue growth shows that expansion is already feeding through to the income statement, while the wider loss illustrates the cost of scaling at the same time. Public investors will now be asked to value both sides of that equation against a portfolio whose physical delivery programme remains central to the financial outcome.
