The Q1 FY26 print lands: net profit down 18%, Arm's post-earnings slide erases ¥14T of pro-forma NAV, and the stalled $10B OpenAI-collateral loan gets signed

What happened

SoftBank Group's Q1 FY2026 (quarter to 2026-06-30) results, released as scheduled 2026-08-06 JST: net income ¥347.3B, down 18% YoY (from ¥421.8B) despite investment gains surging roughly 300% YoY to ¥1.86T — the gain was almost entirely ByteDance (¥2,221M of a ¥2,394M SVF1 quarterly gain) and Intel (¥1.33T of unrealized gains), not OpenAI, which recorded no valuation gain this quarter. SoftBank Group shares fell 4.41% on the print itself, reversing the pre-print rally recorded here 08-05. (Investing.com, Daily Sabah)
This directly answers the "Arm's post-earnings slide" ledger question: quarter-end NAV hit a record ¥72.3T ($445.2B) as of 06-30, but a same-release pro-forma mark as of 08-05 shows NAV down to ¥58.3T — a ¥14T (~19%) reduction — driven specifically by Arm's own contribution to that NAV falling from ¥43.4T to ¥31.1T. Arm's own Q1 print (07-29) beat on revenue ($1.29B, +22% YoY) and EPS ($0.45), but shares still fell ~8% same-day and continued sliding into August (−3.15% on 08-05) on a supply-demand mismatch (AGI CPU demand >$2B vs ~$1B secured supply) and smartphone-royalty softness — that slide is what shows up as the ¥14T NAV cut. ⚠ The pro-forma figure is single-sourced (Investing.com); treat as directionally confirmed, not exchange-verified.

The second ledger item resolves too: the OpenAI-stake margin loan that stayed "stalled on valuation concerns" as of 08-03 is now signed. Bloomberg (08-06): SoftBank secured a $10B, two-year margin loan against its OpenAI stake, agreed 2026-08-05 with Goldman Sachs Bank USA, JPMorgan Chase Bank NA, Mizuho Securities USA, Apollo Global Funding and Sumitomo Mitsui Banking Corp, with drawdown planned this month. Combined with the $30B already funneled to OpenAI via Vision Fund 2 and the existing $40B bridge loan, SoftBank's total OpenAI-linked commitments now exceed $60B — cumulative OpenAI investment is reported at $32.4B as of 03-31-2026, projected to $64.6B by 10-01-2026 for roughly a 13% stake, consistent with the three $10B tranches (04-01, 07-01, planned 10-01) already on this thread's record.

Balance-sheet detail: cash fell to ¥2.3T from ¥3.5T; loan-to-value stayed at 13%, well inside the self-imposed 25% cap — the $30B H2-2026 obligation flagged 08-04 is still outstanding and unaddressed by this print. CFO Goto pushed back on bubble framing on the earnings call: "There's clear demand and an overwhelming shortage of supply" on AI datacenter buildout, "I think we're in a very healthy state."
