For those asking: • Our pre-IPO shares will be adjusted for the stock split. • Our cost basis remains below the initial marketed price. Focused on long-term value creation. reuters.com/business/aerospa… @bitcoincojp - #spacex #bitcoin #japan

Why doesn’t Bitcoin Japan Corporation own #Bitcoin yet? A fair question The answer is simple: We believe in Bitcoin. We refuse to be reckless with shareholder capital. Today, @bitcoincojp owns ZERO Bitcoin. Not because we lack conviction. Because our responsibility is to maximize long-term shareholder value, not blindly follow a narrative. Our thinking is straightforward: 1. Build the foundation first. Before owning a single satoshi, we wanted the right governance, compliance framework, custody partners, security architecture, auditors, and operational controls in place. Institutional infrastructure comes before institutional capital allocation. 2. Security matters more than speed. One mistake in digital asset custody can erase years of value creation. We have prioritized doing this correctly over doing it quickly. 3. Bitcoin is a great asset. Price still matters. We believe Bitcoin is one of the most important stores of value of our generation. The long-term case is strengthened by: • Rising sovereign debt • Persistent fiscal deficits • Monetary debasement • Growing distrust in fiat systems But even great assets can be poor investments at the wrong price. Demand, supply, liquidity conditions, market structure, and technical indicators all matter. Patience is part of our strategy. 4. We will not issue shares simply to buy Bitcoin. Many companies are pursuing Bitcoin treasury strategies. We respect that. But our job is not to buy Bitcoin at any price. Our job as fiduciaries of shareholder capital is to create value per share. Every capital allocation decision must meet that standard. 5. We see a broader opportunity set. We are currently seeing extraordinary opportunities across: • AI infrastructure • Data platforms • Compute and energy • Intelligent software systems • Digital financial infrastructure • Rare earths We intend to be a leading company in the AI and Bitcoin economy. 6. The time to act is getting closer. Our conviction in Bitcoin has never been stronger. We fully expect Bitcoin to become part of the company’s treasury assets. The question has never been if. The question has always been when. Until then: • Protect capital • Build the platform • Stay disciplined • Wait for asymmetric opportunities • Act decisively when the odds are in our favor Sometimes the hardest trade is waiting. Patience pays. $8105 #japan #tokyo #ai #bitcoin #btc

AI infrastructure, Bitcoin reserves, and disciplined governance — that’s our growth thesis.
