Cyanotech Reports Financial Results for the Fourth Quarter and Fiscal Year 2024

KAILUA KONA, Hawaii (June 26, 2024) — Cyanotech Corporation (OTCQB Market: CYAN), a world leader in microalgae-based, high-value nutrition and health dietary supplement products, announced financial results for the fourth quarter and fiscal year 2024, ended March 31, 2024.

Commenting on the fiscal year results (changes shown vs. fiscal 2023), Cyanotech’s President and Chief Executive Officer, Matthew K. Custer, said:

“Although the year was filled with challenges, our team effectively managed spending, production and inventory to conclude the year with only slightly increased debt of $209,000. As we look forward to this next year, and the increasing interest we are currently seeing in our products along with new product offerings, we are now turning our focus to meeting this demand with a well-managed increase in supply. We have preliminarily secured the financing to ensure we can meet market demand.”

“Our sales were essentially flat with the prior year, however, the product mix shifted as we saw an increase in our packaged sales. This increase was offset by declines in spirulina bulk sales as the market for bulk material is increasingly price sensitive with many companies sourcing lower priced international ingredients.”

“Our re-aligned commercial function continues to expand on and create market awareness with strategic initiatives. These initiatives include restructuring the sales team to bolster both the business to business and business to consumer channels, aligning our selling materials and messaging with our commitment to transparency and sustainability, and refining our core value proposition to emphasize and educate the consumer about our high-quality farm-direct, and responsibly grown products. We have also expanded our product offerings by launching our BioAstin® Hawaiian Astaxanthin® and Hawaiian Spirulina® in new, convenient gummy formats.”
