Data Center Firm DayOne's US IPO Gets Cold Reception as ByteDance Accounts for Nearly 70% of Revenue
nashnova research
Singapore-based data center operator DayOne is considering halving its US IPO fundraise from $5 billion to $2.5–3 billion, and may delay the listing altogether — just two weeks after filing, the market is flashing warnings on high valuation, heavy assets, and extreme client concentration.
Who is DayOne, and why list in the US?
DayOne is headquartered in Singapore. It builds hyperscale data centers — facilities supplying server space, power, and cooling to major internet and cloud companies — across Southeast Asia, on contracts typically lasting 10–15 years.
On October 5 it filed an F-1 prospectus with the SEC, targeting a Nasdaq listing at roughly $20 billion valuation with up to $5 billion in proceeds.
This means → DayOne aimed to ride the AI-driven compute boom by selling Southeast Asian data center growth to US investors.
Nearly 70% of revenue from one client — how risky is that?
The prospectus shows a single top customer contributing 69.4% of 2025 revenue and 69.2% in H1 2026. The Information identified that customer as ByteDance.
In plain terms = if ByteDance cuts orders or squeezes pricing, nearly seven-tenths of DayOne's top line is immediately at risk — textbook client-concentration exposure.
Growth is undeniably fast: 2025 revenue hit $484 million (+172% YoY); H1 2026 reached $512 million (+238% YoY) — six months already exceeding the prior full year.
This reflects a genuine explosion in Southeast Asian data center demand, but the faster the growth, the more it magnifies single-client risk.
Growing this fast — so why is it still losing money?
Net loss attributable to shareholders was $369 million in 2025 and $82 million in H1 2026. The 2025 figure ballooned largely because of $342 million in share-based compensation (equity incentives for staff and early team members).
The cash-flow picture is starker: H1 2026 capex — land, construction, equipment — totaled $3.11 billion, roughly six times the period's revenue, while net operating cash flow was just $14 million.
This means → DayOne is a textbook "burn now, scale later" story — revenue is climbing, but every dollar of revenue requires about six dollars of upfront construction spending, all funded externally.
What else is on the balance sheet? What does $6.4 billion in "mezzanine equity" mean?
As of end-June 2026: total assets $12.84 billion, total liabilities $6.50 billion, debt-to-asset ratio 50.62%, interest-bearing debt $4.43 billion.
The balance sheet also carries $6.36 billion in mezzanine equity — convertible preferred shares issued in Series A, B, and C rounds. These sit between debt and equity and come with a hard trigger: if no IPO is completed by end-2030, qualifying majority shareholders can force the company to begin a formal exit process.
In plain terms = early investors are not patiently waiting — they set a deadline. Miss it, and management must find a way to return capital or arrange an alternative exit. That clause creates enormous pressure to list.
Is DayOne alone — or is the whole data center IPO market cooling?
Firmus, an Nvidia-backed Australian data center firm, shelved its planned ~$5 billion IPO on October 9. It had sought a $30.6 billion equity valuation, but investors balked at limited operating history and high debt.
AirTrunk (Blackstone-owned) also postponed its Singapore REIT listing, which had targeted roughly $1.5 billion in proceeds.
This means → three data center IPOs scaled back or delayed in quick succession — Firmus, AirTrunk, DayOne — signaling a collective market repricing of "high valuation + heavy capex + unproven profitability" data center stories.
If the raise is halved, what does that mean for DayOne?
Cutting proceeds from $5 billion to $2.5–3 billion would directly constrain DayOne's next expansion cycle.
Billed capacity reached 666 MW by end-June (up from 213 MW a year earlier — more than tripling), and expansion is accelerating — but the faster it grows, the more it depends on fresh capital.
This reflects the core question the market is posing to DayOne: can a model that ties nearly 70% of revenue to a single client and burns cash at massive scale win buy-in from public-market investors?
