Cyanotech Reports Financial Results for the Third Quarter and First Nine Months of Fiscal 2023

KAILUA KONA, Hawaii (February 9, 2023) — 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 third quarter and first nine months of fiscal year 2023, ended December 31, 2022.

Commenting on the third quarter fiscal year 2023 results, Cyanotech’s President and Chief Executive Officer, Matthew K. Custer, said:

“Sales in the third quarter improved by $712,000, or 14%, compared to the second quarter, as we saw modest improvement in consumer movement on both finished goods and bulk sales.  However, both of our online finished good sales and our international bulk sales are still not performing to historical levels.  On the international bulk sales, as the global supply chain issues eased, customers made adjustments to their inventory levels that impacted our sales.  The inventory levels have improved but are still a headwind.  We are focused on taking steps and making changes to improve these sales channels.”

“The cash saving initiatives that we implemented in the second quarter, including slowing production and reducing headcount, were not fully realized until late in the third quarter, due to material lead times and payment terms.  However, our working capital remains strong due to higher inventories that have long expiration dates.”

Third Quarter Fiscal 2023

Cyanotech reported net sales of $5,891,000 for the third quarter of fiscal 2023 compared to $9,459,000 for the third quarter of fiscal 2022, a decrease of 37.7%. Gross profit was $1,764,000, with gross profit margin of 29.9%, compared to gross profit of $3,238,000, with gross profit margin of 34.2%. Operating loss for the third quarter of fiscal 2023 was $404,000 compared to operating income of $508,000 in the same period of the prior year. Net loss for the current fiscal quarter was $598,000, or $0.10 per diluted share, compared to net income of $386,000, or $0.06 per diluted share, for the same period of the prior year.

Cyanotech reported net sales of $17,786,000 for the first nine months of fiscal 2023 compared to $27,842,000 for the same period in fiscal 2022, a decrease of 36.1%.
