Cyanotech Reports Financial Results for the First Quarter of Fiscal 2023

KAILUA KONA, Hawaii (August 10, 2022) — Cyanotech Corporation (Nasdaq Capital Market: CYAN), a world leader in microalgae-based, high-value nutrition and health dietary supplement products, announced financial results for the first quarter of fiscal year 2023, ended June 30, 2022.

Commenting on the first quarter fiscal 2023 results, Cyanotech’s President and Chief Executive Officer, Matthew K. Custer, said: “The disappointing results in the first quarter were driven primarily by the $2.2 million decrease in sales and a higher cost per kilo of astaxanthin.  Lower sales in the quarter related to timing of shipments to a Nutrex customer as we transitioned to their selling platform in the prior year, as well as a decrease in bulk spirulina sales.  The increase in cost for astaxanthin was driven by lower production in the first quarter due to staff shortages.  Production levels normalized late in the first quarter.”

First Quarter Fiscal 2022

Cyanotech reported net sales of $6,716,000 for the first quarter of fiscal 2023 compared to $8,964,000 for the first quarter of fiscal 2022, a decrease of 25.1%. Gross profit was $2,318,000, with gross profit margin of 34.5%, compared to gross profit of $3,672,000, with gross profit margin of 41.0%. Operating loss for the first quarter of fiscal 2023 was $425,000 compared to operating income of $619,000 in the same period of the prior year. Net loss for the current fiscal quarter was $472,000, or $0.08 per diluted share, compared to net income of $520,000, or $0.08 per diluted share, for the same period of the prior year.

Trailing Twelve Months

For the trailing twelve months ended June 30, 2022, compared to the trailing twelve months ended June 30, 2021, net sales were $33,720,000 compared to $33,957,000.  Gross profit was $12,212,000, with gross profit margin of 36.2%, compared to $11,813,000 and 34.8%.  Net income was $1,161,000, or $0.19 per diluted share, compared to net income of $1,302,000, or $0.21 per diluted share, which included $1,389,000 for the forgiveness of the loan under the Paycheck Protection Program.
