Oklo (OKLO) widened losses for the first quarter late Tuesday but matched analyst estimates. Oklo stock slumped near a key level on Wednesday, with other nuclear stocks seeing mixed action.

Several other nuclear companies have already reported AI-fueled earnings. Siemens Energy (SIEGY), an energy giant, raised outlook on Tuesday after a strong quarterly earnings report.

Nuclear energy and gas-fired power are capitalizing on the boom in data centers and artificial intelligence (AI).

Oklo Earnings, Cash Balance And Cash Burn

Late Tuesday, Oklo reported a net Q1 loss of $33.1 million vs. $17.9 million a year ago. On a per-share basis, the nuclear startup lost 19 cents, in line with analyst estimates and comparing with a 7-cent loss a year ago, according to FactSet.

The company also reported $17.9 million in operating cash burn and $32.8 million in capital expenditures. Oklo updated investors across its three business lines — power, fuel and isotopes — as well.

Nuclear startup Oklo is racing to meet a critical July 4 deadline.

Last week, Oklo announced a regulatory design milestone for its Aurora powerhouse, under construction in Idaho. On Tuesday, ahead of its earnings report, Oklo announced a partnership with Idaho National Laboratory on AI-enabled advanced nuclear reactors. It also has a notable partnership with Meta (META).

Oklo Stock, Nuclear Stocks

Shares of Oklo dived 5.4% on the stock market today. Oklo stock slid 5.8% on Tuesday ahead of the Q1 report.

Oklo stock rallied above the 50-day moving average in mid-April. Shares have been trading sideways for the past few weeks, holding the 21-day line but stuck below the 200-day.

Nuclear stocks were mixed on Wednesday.

U.S.-listed shares of Siemens, which trade over the counter, popped 4.6% after earnings. The nuclear infrastructure stock broke out ahead of the company's Q1 report. Siemens Energy supplies nuclear fleets with equipment and services, including SMR turbines.

NuScale Power (SMR), another SMR startup, plunged nearly 10% on Tuesday and rebounded 1.6% on Wednesday. NuScale reported Q1 results last week.

Ahead of Tuesday's report, analysts generally cut price targets on Oklo stock, FactSet shows. Many cited execution risk.

Oklo ended 2025 with about $1.4 billion in cash and securities. That shored up the balance sheet, with the startup eyeing a 2028 start of operations for its Aurora small modular nuclear reactors (SMR). It burned $60.4 million of cash in Q4 2025, up from $23.1 million in Q3. Oklo expects to sharply increase capex in 2026.

Over the past year, Oklo stock more than doubled, surging 118%. However, it rallied 33.5% in the past month after Q1's slump.
