✦ Eight Hundred Billion Yen, and a Three-for-One SplitNarrow moat

Kioxia Holdings (285A) — the future bets

Debt repaid is permanent; shares bought at 52,500 yen after a 53 percent fall are a judgement about the cycle rather than about the company.

A company that was levered at 1.26 times equity eighteen months ago is now buying its own shares.

What the windfall is being spent onSenior loans repaid¥407.5bn - permanentBuyback authorisedUp to ¥800.0bn, 5.5% of the sharesCapacity planned~¥470bn a year for three yearsShare splitThree-for-one, effective 1 October 2026Buying stock at ¥52,500 after a 53% fall is a judgement about the cycle.
Debt repaid cannot come back. Shares bought at a peak can.

In August 2026 Kioxia authorised the repurchase of up to 30 million shares — about 5.5% of those outstanding — for up to ¥800.0 billion, running from 3 August to 30 October 2026, alongside a three-for-one share split with a 30 September record date1. It had reached a net cash position of ¥186.7 billion in the June quarter after repaying ¥407.5 billion of senior loans, with the equity ratio at 51%2.

The split is cosmetic and useful: a ¥54,570 share is awkward for Japanese retail investors, who trade in lots of 100.

The buyback is a judgement, and it is the interesting part. Management's stated framework is to evaluate returns on the basis of cumulative free cash flow in excess of requirements over multiple years3 — a deliberately conservative formulation for a cyclical business. Buying ¥800 billion of stock at more than 50% below the June high is a statement that the shares are cheap after the fall, which is a view about the cycle as much as about the company.

The alternative use is obvious and is being pursued in parallel: roughly ¥470 billion a year of capacity4.

The number to watch is how much cash remains when flash prices turn. Debt repaid is permanent; shares bought at a cyclical peak are not.

Moat trajectory: Widening

The first serious capital return in the company's public life, made possible by reaching net cash and investment grade in the same year.

The number that tests this moat
Reported
Non-GAAP earnings per share, latest quarter
¥1,621.81 in the June 2026 quarter; ¥2,335.70 guided for September (before the split)

The buyback retires shares at prices set by these earnings; a guided figure missed would make the ¥800bn look early.
