Oklo Inc. Chief Legal & Strategy Officer William Carroll Murphy reported routine equity compensation activity. On May 19, 20,686 restricted stock units vested, converting into the same number of Class A common shares. Footnotes state each RSU represents a contingent right to one Class A share.

On May 20, 10,548 of these shares were sold at $58.04 per share solely to cover tax withholding obligations through a “sell to cover” transaction, described as non-discretionary. After these transactions, Murphy directly holds 36,175 Class A shares and 146,072 RSUs, with the RSUs part of a 248,227-unit grant awarded on August 12, 2024.

Oklo Inc. has filed a prospectus supplement to sell up to $1,000,000,000 of Class A common stock through an Equity Distribution Agreement with multiple sales agents as an at-the-market offering.

The Sales Agreement permits sales from time to time through brokers, market makers, the NYSE, private negotiated transactions, block trades, or forward sale structures (including range and collared forwards). The offering proceeds will be used for general corporate purposes, working capital, capital expenditures, and potential investments. The prospectus cites 173,867,839 shares outstanding as of March 31, 2026 and discloses compensation to sales agents of up to 1.5% of gross sales price.

Oklo Inc. entered into a new equity distribution agreement with a syndicate of investment banks to sell, from time to time, up to $1,000,000,000 of Class A common stock through an at-the-market offering program. Sales may be made on the New York Stock Exchange and other permitted venues at market or negotiated prices, with the company paying up to 1.5% in sales commissions.

Oklo simultaneously terminated its prior equity distribution agreement, which had allowed offerings of up to $1,500,000,000. Under that prior program, the company sold 15,774,224 shares of common stock for gross proceeds of approximately $1,499,867,429, and it incurred no termination penalties. Future sales, if any, will occur under the new agreement and related prospectus supplement filed under the existing Form S-3 shelf registration.

Oklo Inc. reported a larger quarterly loss as it accelerated investment and strengthened its balance sheet. For the three months ended March 31, 2026, the company posted a net loss of $33.1 million, compared with $9.8 million a year earlier, as research and development and general and administrative expenses rose to $27.0 million and $24.2 million, respectively.

Higher spending reflects headcount growth and sharply increased stock-based compensation, while interest and dividend income climbed to $21.3 million on a much larger cash and securities base. Oklo finished the quarter with $2.54 billion in cash, cash equivalents, and marketable debt securities and total assets of $2.70 billion, against modest liabilities of $64.9 million, leaving stockholders’ equity at $2.64 billion.

The company completed a 2025 at-the-market equity program in Q1 2026, issuing about 12.4 million shares for net proceeds of roughly $1.18 billion, and used $17.9 million of cash in operating activities and $32.8 million for capital expenditures. Management believes existing liquidity will fund operations for at least one year as Oklo advances its Aurora fast fission powerhouses, fuel recycling and fabrication projects, and radioisotope initiatives.
