Cyanotech stock gained 17.14 percent to USD 0.41 on October 2, 2026, at 4:00 p.m. ET. The move followed a prior close of USD 0.35 and gave the small OTC-listed company a market capitalization of USD 3.0 million.
Stock move sets the daily frame
The October 2 trading range ran from USD 0.31 to USD 0.45, while volume reached 8,850 shares. The price stood 28.1 percent above the session low and 8.9 percent below the session high, putting the daily move near the upper end of its range.
Cyanotech stock remained within a 52-week range of USD 0.23 to USD 0.57 as of October 2, 2026. The last price was 28.1 percent below the 52-week high, leaving the yearly trading band substantially wider than the single-session move.
Hawaiian microalgae drives the business
Cyanotech cultivates, produces and sells natural products derived from microalgae for health and human nutrition markets. Its product portfolio includes BioAstin Hawaiian Astaxanthin and Hawaiian Spirulina Pacifica.
The company began its farm in 1984 and operates 90 acres of cultivation ponds in Kailua-Kona, Hawaii, according to Cyanotech. This operating footprint links the stock to a specialized production base rather than a diversified consumer-products portfolio.
Small capitalization magnifies volume
The USD 3.0 million market capitalization and 8,850-share volume on October 2, 2026, place the session in a small-capitalization trading context. A USD 0.06 increase represented 17.14 percent against the USD 0.35 prior close, so the percentage move was larger than the absolute change suggests.
Cyanotech also reports annual electricity production of 1,147,000 kilowatt hours from a 1.3-acre solar array. The company links that infrastructure to its microalgae cultivation model and environmental operating strategy.
USD 0.41 remains below yearly high
Cyanotech stock was last at USD 0.41 on the OTC market on October 2, 2026, at 4:00 p.m. ET. The price was USD 0.16 below the 52-week high of USD 0.57.
