$BLGO After a string of real, value-generating milestones over the last ~150 days, it’s honestly hard to justify a sub-$40M valuation here. This isn’t hype — it’s execution: ✅ Lake Stockholm AEC install (Jan 27, 2026) — live, in-ground, under NJDEP & EPA oversight. First real municipal PFAS deployment. ✅ Clyra first stocking order (Feb 2026) — secured via Advanced Solutions’ national distribution. Hospitals and clinics. Revenue underway. ✅ Al Hikma deal (May 5, 2026) — exclusive MENA distribution for ViaCLYR™ across GCC and Levant markets. ✅ $1.2M Minerals contract (Apr 20, 2026) — BioLargo Engineering leading pilot-scale facility design. ✅ Aquatech MOU (May 3, 2026) — another AEC partnership advancing. On top of that: revenues rebounding from last year’s lows with 81% QoQ growth in Q4. Price is what you pay. Value is what you get. And right now, the gap between the two is hard to ignore.
View on StockTwits ↗$BLGO There needs to be an investors meeting and talks need to happen on why sales are not happening here. It's been way too many years of empty promises and this company never has a significant money making deal
View on StockTwits ↗$BLGO Where's that gorilla Clyra order BLGO has been talking about for three years???? Why did it never come to fruition???
View on StockTwits ↗$BLGO Julian would rather believe in a single tireless super-basher than accept that years of empty promises and a cratering stock price can convince more than one person that this is a bad investment. He says he's but hundreds of dollars worth of stock, but he will need to increase that substantially to keep this ship afloat.
View on StockTwits ↗$BLGO BLGO doesn't understand that just talking about possibilities doesn't generate actual revenue and certainly after two decades won't generate ANY investor interest. If the current leaders can't sell anything the Board is obligated to bring in people that can.
View on StockTwits ↗🤔 Serious question though… if $BLGO is such a worthless, going-nowhere penny stock — why has our resident basher spent YEARS of his life dedicated to a company he claims will never succeed? Most people move on from bad investments… but dedicating your LIFE to bashing one? That’s not skepticism, that’s an obsession. 😂 Maybe HE knows something big is coming! 👀 I am adding 😉 #BioLargo #PFAS #CleanTech #Undervalued $BLGO 🌊
View on StockTwits ↗🚀 $BLGO FACTS ONLY, NO HYPE 👇 💧 AEC PFAS system IN THE GROUND in NJ & MOU with Aquatech for global rollout 🩺 Clyra’s ViaClyr™ FIRST stocking order + Middle East/Africa distribution deal signed 🔋 Cellinity Battery JVs forming — clean energy storage could be the NEXT big catalyst ⚒️ BEST division lands $1.2M minerals processing contract — NEW revenue vertical unlocked 💰 $10M funding commitment secured + $3.9M cash — they are FUNDED & EXECUTING 📈 Engineering revenue up 98% YoY — organic growth is REAL 2026 = commercialization across ALL FOUR divisions. This is not a maybe. This is a WHEN. 🎯 #BioLargo #PFAS #CleanTech #Undervalued $BLGO 🌊

View on StockTwits ↗$BLGO Here is a quote from Dennis about the batteries from a January 1 2024 interview: "The fact that we can put a small facility with our own resources together and have a manufacturing facility in four months that can produce thirty plus million dollars a year. I mean and you could do twenty of those little projects and you have a 100 million a year flowing through this business and of course its technology that others are going to want." What happened to that easy 30 mil per year? 🤔
View on StockTwits ↗$BLGO Nearly $3000 traded so far today in this leader in clean tech. Wow. The excitement just keeps building and building! 🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡
View on StockTwits ↗$BLGO https://essinc.com/ess-to-accelerate-sodium-ion-battery-energy-storage-system-development-following-surging-customer-interest/ isn't blgo involved in this. They need to hire a new sales team. This is getting ridiculous at this point
View on StockTwits ↗$BLGO outstanding warrants beginning 2026 was 31,730,651 the first warrants expired April 16, 2026 don’t know how many the rest will expire end of year the strike exercise is between.19-.26 if that’s price isn’t met all those warrants go bye bye
View on StockTwits ↗$BLGO Either the market is completely mispricing this - or it still hasn’t understood what ClyraSept actually is. A co-branded launch with a global leader isn’t “nice to have” - it’s the kind of validation most microcaps never get. Yet it’s still sitting at ~$35M like nothing’s about to happen? We already saw 7-year highs just on anticipation. Delays killed the momentum- and now nobody seems to care anymore. That’s usually where the opportunity is. If this launch hits in 2026, today’s pricing will look ridiculous in hindsight. Or the market is right and this never materializes. No middle ground. Do your own DD. https://advancedsolution.health/viaclyr/
