• [Hard positive] — TODAY: DOE formally approved the Nuclear Safety Design Agreement for Oklo's Aurora Powerhouse at Idaho National Laboratory. This is a material licensing milestone — the DOE must complete this review before construction authorization can proceed.
• [Hard positive] — Apr 16: Energy Secretary confirmed first 5–10 new nuclear reactors will "almost certainly" receive DOE loan guarantees. OKLO is the leading SMR candidate.
• [Macro] — OKLO ripped from mid-$40s (late March) to low $70s by Apr 22. +8.08% today extends the run.
• [Soft] — Pre-revenue company (~$788M cash, -$41M quarterly net income). High-beta name — prior "sell the news" pattern on milestone announcements worth monitoring.

Today's DOE Nuclear Safety Design Agreement approval is a genuine regulatory milestone, not just sentiment. It is a required step before Oklo can receive DOE construction authorization. The DOE loan guarantee commitment from the Energy Secretary (Apr 16) plus this structural approval materially de-risks the financing and permitting path. The +8.08% move is proportionate to the news. Watch whether this sticks or produces the "sell the news" pattern seen in early April.

• [Hard positive] — Recent DOE approvals for Aurora Powerhouse design; first NRC materials license (Atomic Alchemy — Ra-266, Co-60, Am-241).
• [Macro positive] — White House April 16 mandate for federal nuclear-in-space deployment (orbital by 2028, lunar by 2030) — sector tailwind.
• [Technical mixed] — Down 20% since DOE approval ("sell the news"); stock at ~$67.88 from $64.21 over April 16-17.
• [Macro] — Up 32% past week, 192% past year. Consensus PT $90.41.

Approval cycle has produced "sell the news" reactions even as the broader nuclear-policy backdrop strengthens. No acute risk signal today. Watch the URA/SMR ETF basket; OKLO trades with the theme.
