BMNR Pivots to Buybacks at 0.85x | Week of Jul 20

BitMine announced this week that its ETH holdings reached 5.78 million tokens, roughly 4.8% of the 120.7 million ETH supply, with total crypto and cash holdings of $11.5 billion. The headline number is almost beside the point. The real story is what Tom Lee did with the cash: the company repurchased approximately 5.5 million common shares at an average price of $15.6156 under its $4 billion buyback authorization, and bought only 7,430 ETH. Lee was explicit that the reduced ETH pace reflects the buyback, and noted the company has still bought ETH every week since the treasury strategy launched on June 30, 2025. Source

The buyback math, run honestly

Start with what 5.5 million shares at $15.62 actually costs: about $85.9 million. Our NAV Analysis puts NAV per share at $18.91 this week, which means BitMine paid roughly 82.6 cents for every dollar of net asset value it retired. That's approximately $18.1 million of NAV transferred to remaining shareholders in a single week, mechanically, with no market risk attached.

Compare the alternative. That same $85.9 million buys about 45,900 ETH at $1,872. Buying ETH at a stock trading below NAV grows the asset pile but does nothing for the per-share discount. Buying stock at 0.85x closes the gap from both ends. When your own equity is the cheapest ETH exposure available, you buy the equity. Lee clearly agrees, and this week the mNAV responded: up 0.065x to 0.85x, with NAV per share climbing 1.54% even though ETH itself was roughly flat. If the premium/discount mechanics are new to you, What mNAV Means walks through why a sub-1.0x multiple makes buybacks the highest-conviction trade a treasury company can make.

The number that deserves more scrutiny

Here's the wrinkle almost nobody will mention: despite repurchasing 5.5 million shares, shares outstanding rose by 887,286 week over week, to 604,113,680. That implies roughly 6.4 million shares were issued elsewhere, likely compensation, option exercises, or settlement of prior ATM activity. So the buyback didn't shrink the float this week. It offset dilution that would otherwise have hit NAV per share.

That's still accretive, to be clear. Offsetting dilution at a 15% discount to NAV beats letting it land. But investors modeling a shrinking share count should reset expectations: for now the buyback is a dam, not a drain.

Week over week

Staking held flat at 4,917,189 ETH, which the company values at $9.2 billion at $1,879 per ETH and which BitMine says is more staked ETH than any other entity holds. That's 85% of the treasury generating yield on the MAVAN platform, quietly compounding while the capital allocation debate plays out up top.

What this means for the 6M goal

The march to 6 million ETH sits at 96.29%, with 222,532 ETH remaining and an estimated 38 days to go. And here's the tension: at this week's pace of 7,430 ETH, that gap takes about 30 weeks to close, not five and a half. Something gives. Either the buyback throttles back once the discount narrows, or the goal timeline slips, or a larger capital raise arrives once the stock trades closer to NAV (which would be the rational sequence: buy back below 1.0x, issue above it). You can watch the accumulation pace in real time on the Treasury Dashboard.

One more note for the cost-basis watchers: the average buy price sits at $3,102 against a spot price of $1,871.6, so the ETH position is roughly 40% underwater on cost. Cost basis is backward-looking and shouldn't drive forward decisions, but it does explain the market's caution, and it makes the discount-capture logic of buybacks even cleaner. Why average down into ETH at market when your own shares offer ETH at 85 cents on the dollar?

For investors

The signal this week is discipline. Management looked at a 15% NAV discount and directed capital where the return was highest and most certain, at the cost of a slower headline accumulation number. The mNA
