IonQ printed 71.6% more shares to buy its quantum empire. November reveals the next tranche.
Diluted shares are up 71.6% in under two years to buy Oxford Ionics and SkyWater, and the $2.12 billion cash cushion grows only because new equity arrives faster than the burn. November's Q3 print puts SkyWater's 24 million shares in the count for the first time.

A Korea deal lands on a balance sheet built from stock
IonQ announced on 21 September a multi-year deal with Korea's SDT: the country's first Superion 256 system and silicon-vacancy quantum memory module, plus a Gumi plant to package that memory and assemble machines 12. Deliveries are expected in 2027 1. SDT chief executive Jiwon Yune calls Gumi "a key operational hub for IonQ's global supply chain" 2. The expansion runs on a balance sheet with one dominant input: IonQ's own shares.
The share count is the funding model
Since September 2024, diluted weighted-average shares have climbed from 214.31 million to 367.66 million, up 71.6% 3. That currency bought Oxford Ionics for roughly $1 billion in September 2025 and SkyWater Technology for $1.8 billion, closed 31 July, both paid mostly in stock 3. SkyWater's holders took about $741 million in cash plus roughly 24 million new shares, near 6% of the company 4.
The count has since flatlined between roughly 358 million and 369 million; the small dip into June is weighted-average timing, not retirement 3. At Investor Day, chief executive Niccolo de Masi was blunt: "we raised $3.4 billion last year" 5. Name the sides and the trade is one line: Oxford Ionics and SkyWater holders, and IonQ's cash account, took the value; existing IonQ holders supplied the currency 34.

The cushion grows because the equity does
Cash and short-term investments rose from $2.03 billion to $2.12 billion in the second quarter while IonQ burned $113.97 million of free cash flow, after $159.39 million in the first 3. That closes one way only: financing arrived faster than cash left 3.
Twelve straight quarters of negative free cash flow sit alongside cash and equivalents climbing from about $37 million to $1.24 billion 6. The runway is not an asset. It is the dilution, parked in a cash account.

About $1.05 billion of it left at the SkyWater close anyway: $741 million to foundry holders, roughly $315 million to retire debt and cover deal costs, leaving about $2.0 billion pro forma 47.
A third of the guidance is a foundry IonQ just bought
The bull case has receipts: $80.1 million of second-quarter revenue, up 287%, and $485 million of performance obligations against $122 million a year earlier 3. The Korea deal feeds the same stack, with first deliveries in 2027 12.
The September guidance lift is softer evidence. The new range of $450 million to $460 million 8, up from $280 million to $290 million set in early August, is the third raise this year and the first that is consolidation rather than the quantum business beating its own forecast 9. Finance chief Inder Singh's bridge nets SkyWater's five stub months to about $170 million after eliminating roughly $70 million IonQ itself pays the foundry: more than a third of the total, on an organic rate still near 132% 3.
The cost side widened faster. Adjusted EBITDA was a $120.3 million loss for the quarter against $36.5 million a year earlier, and gross margin fell to 24.9% from 59.8% as hardware displaced cloud 107. Management said it could not yet give combined-company EBITDA guidance, days after the close 3.
November counts the missing shares
SkyWater's 24 million shares sit in no reported count yet. They arrive with third-quarter results, due in November, alongside the first combined-company adjusted EBITDA guidance 34. A foundry with thousands of wafers in production adds capital spending to a burn that stock, not earnings, has always covered 3.
The printing press has bought more than three years of runway and a manufacturing stack 3. November prices the next run.
