Fundamentals and Valuation
Oklo’s balance sheet reflects a company still in heavy development mode. The trailing twelve‑month (TTM) price‑to‑earnings ratio sits at ‑41.78, a negative multiple that signals earnings are currently in the red. The enterprise‑value‑to‑EBITDA metric is similarly negative at ‑34.52, reinforcing the cash‑burn narrative. Book value multiples are more modest, with a price‑to‑book (P/B) of 2.14, suggesting the market values the firm at just over twice its net asset base.
Profitability metrics remain deeply negative. Return on equity (ROE) is ‑7.11 %, while return on assets (ROA) trails at ‑4.55 %. Gross margins are the lone bright spot, recorded at 26.94 %, indicating that once the technology reaches commercial scale, the core cost structure could be attractive. Operating and net margins, however, are extreme outliers at ‑18,003.6 % and ‑12,625.5 %, respectively—reflecting the heavy R&D and capital‑intensive nature of building advanced fission reactors.
Cash‑flow history underscores the challenge. Free‑cash‑flow (FCF) has been consistently negative, moving from a ‑$1.94 M deficit in 2021 to a ‑$115.38 M shortfall by the end of 2025. Earnings per share (EPS) have deteriorated each year, slipping from ‑$0.08 in 2021 to ‑$0.72 in 2025. The company’s debt‑to‑equity ratio remains low at 0.13, indicating modest leverage, but the balance sheet is dominated by equity financing and cash burn.
Analyst sentiment is surprisingly upbeat. The consensus target price is $84.57, more than double the current market price, and the prevailing recommendation is a Buy. This divergence between market pricing and analyst expectations fuels the LOPJLB “Value” score of 3.00 and “Growth” score of 4.00, though the “Quality” metric is 0.00, reflecting the volatile earnings profile.
| Metric | Value |
|---|---|
| P/E (TTM) | -41.78 |
| EV/EBITDA | -34.52 |
| P/B | 2.14 |
| ROE | -7.11 % |
| ROA | -4.55 % |
| Gross Margin | 26.94 % |
| Op. Margin | -18,003.6 % |
| Net Margin | -12,625.5 % |
| Debt/Equity | 0.13 |
| Analyst Target | $84.57 |
The valuation snapshot illustrates a classic “pre‑revenue” play: the market penalizes current cash‑flow deficits while analysts price in a long‑term upside tied to Oklo’s Aurora modular reactor platform and its fuel‑recycling ambitions. The ‑5 LOPJLB score captures this tension, flagging the stock as over‑extended relative to its near‑term fundamentals.
ETF Ownership
Oklo’s exposure to institutional capital is concentrated in a handful of nuclear‑focused exchange‑traded funds. Sixteen ETFs hold the stock, with the top twelve accounting for the bulk of holdings. The Utilities Select Sector SPDR Fund (URA) leads with 6.09 % of its assets allocated to Oklo, followed closely by iShares MSCI Global Clean Energy ETF (ULTI) at 5.36 %. Other notable holders include North American Nuclear Energy ETF (NLR) at 4.39 %, SMR ETF (SMRF) at 3.84 %, and NUKX at 3.68 %. Concentrated ETF ownership can amplify price moves when fund managers rebalance, especially in a crisis regime where risk‑off flows are common.
The presence of these sector‑specific ETFs underscores Oklo’s positioning as a pure‑play nuclear exposure, but also means that broader sentiment toward the nuclear theme can cascade directly into the stock’s price action.
Earnings Call
Oklo’s most recent earnings call, covering Q2 2026, delivered a milestone: the company achieved first criticality at its Groves isotope facility in roughly 11 months. Management framed the achievement as a “record‑setting pace,” emphasizing that the Groves breakthrough advances an integrated platform spanning power generation, fuel recycling, and isotope production. The call’s one‑liner reads:
“Oklo achieved first criticality at Groves isotope facility in ~11 months, advancing integrated nuclear platform across power, fuel, isotopes with DOE Genesis and campus initiatives.”
Management highlighted parallel progress on the Aurora‑INL pre‑deployment safety analysis (PDSA) submission, a 1.2 GW campus partnership with Meta in Ohio, and a favorable “Part 57 licensing tailwind.” The tone assigned by LOPJLB’s sentiment engine is mgmt = 0.8, indicating confident delivery, though the guidance outlook remains vague for both the remainder of 2026 and the near‑term 2027 horizon.
Earlier in Q1 2026, executives reiterated execution across the three pillars—power, fuel, isotopes—citing the Aurora‑INL PDSA, the Ohio campus, and a target July criticality for the Groves reactor. The recurring theme is rapid translation from strategy to tangible milestones, a narrative reinforced by the 2025‑2026 call history that repeatedly references DOE reactor‑pilot selections, construction starts, and regulatory tailwinds.
Despite the operational wins, management acknowledged ongoing NRC licensing timelines and fuel‑supply constraints that could temper cash‑flow timing. The guidance remains “vague,” reflecting uncertainty around the commercial revenue schedule, which analysts predict may not materialize until 2028 or later. The combination of strong technical progress and ambiguous near‑term financial guidance fuels the mixed‑signal environment that LOPJLB’s model captures.
LOPJLB Signal Read
The LOPJLB engine currently assigns a SELL directional signal to OKLO, with a CRISIS market regime flag. The composite performance score is ‑7.90, while the quality fund score sits at 0.00, indicating limited defensive characteristics. The stock’s Value (3.00), Growth (4.00), and GARP (3.00) scores suggest a balanced blend of upside potential and valuation concerns, but the overarching archetype is Balanced.

What’s Next?
Oklo’s trajectory hinges on whether the technical milestones at Groves and Aurora can be translated into commercial power contracts and sustainable cash flow. The concentration of ETF ownership means that sector‑wide sentiment swings could amplify price volatility, especially under the current crisis regime. Analysts remain bullish on the long‑run upside, but the market’s present pricing reflects a near‑term risk premium that LOPJLB’s model flags as a sell‑side bias.
