Company management provides highlights of the annual report below, but encourages investors to review the full report to get the most complete information about BioLargo and its growing cleantech business, including the risk factors beginning at page 12.

Key financial highlights:

• Consolidated revenue for the year ended December 31, 2022, was $5,884,000, which was a 132% increase over 2021. Revenue in the fourth quarter of 2022 was $2,096,000, a 40% increase as compared with the third quarter of 2022 (quarter-over-quarter), and a 167% increase as compared with the fourth quarter of 2021.
• The company no longer has any outstanding convertible debt.
• The company's total net loss for the year ended December 31, 2022, was reduced by 26% as compared with the prior year, from $6,894,000 to $5,132,000. Approximately 50% of the company's net loss was due to non-cash expenses, including $2,071,000 of stock option compensation expense, and $291,000 of services paid by the issuance of our common stock. Net cash used in operations decreased 30% to negative $2,760,000.
• Net stockholders' equity rose from $933,000 at the end of 2021 to $2,011,000 at the end of 2022.
• The company ended the year with $3.1 million in current assets and working capital of $1.6 million.

Key commercial and developmental highlights:

• Revenues from sales of the Pooph pet odor control product to Ikigai Marketing Works have escalated significantly, resulting from the ongoing success of Ikigai's national marketing campaign for the product and its rollout into Walmart stores in the US.
• The company's AEC water treatment system has been tested and proven to remove per- and polyfluoroalkyl substances (PFAS) from water to below levels required by the EPA's recently proposed limitations of four parts per trillion. These so-called "forever chemicals" accumulate in the human body, are linked to multiple health issues, and are more and more the subject of government regulatory concern.
• The company acquired the IP rights to a sodium-sulfur battery, a technology with unique technical features that enable it to address a need in the market for safe, affordable, long-term energy storage at grid-scale, at electric vehicle charging stations, or similar static applications. The technology is already developed, and BioLargo has formed and secured seed capital for a new subsidiary which will lead the manufacturing, scale-up, and operations for the new technology.
