$AMPX Another solid day. Still waiting for that one BIG day. It'll come. Patience is my middle name.

$AMPX Amprius just dropped a game-changer for anything with wings and no pilot: the SiCore® 500. Packing an eye-watering 500 Wh/kg energy density at a 1C continuous discharge rate, this silicon-anode powerhouse promises to keep drones and high-altitude craft airborne far longer without adding extra weight drag. The absolute kicker? Amprius didn't rely on bespoke black-magic machinery to pull this off—they designed it to be built on standard, conventional lithium-ion manufacturing equipment. That means seamless scalability, standard SAE pouch formats, and zero excuses for your drone running out of juice mid-mission. Unmanned aviation just found its ultimate cheat code!

$AMPX New contracts supplying Drone Dominance winners coming... tens if not hundreds of millions of dollars for them alone. Plus all the other customers... Revenue to 10x+ this coming year... $30 stonk!

$AMPX allow me to translate today’s press release in a nutshell: the highest performing battery cells can now be produced at scale.

$AMPX What a day and what an ending to the week. And it's just getting started. Looks like they let it up. Or had no choice. Looking forward to next week. Have a great labor day weekend all!

$AMPX this isn't a broken-story stock — it's a stock where the business is executing well, but the multiple has compressed anyway. That lines up exactly with the sector read: QuantumScape, Solid Power, Enovix, SES are all getting hit by the same rate-driven de-rating of long-duration growth names, even the ones (like AMPX) posting real beats. AMPX has actually held up better than most of that cohort precisely because it has real, accelerating revenue. So, HODL guys.

$AMPX wait for the volume spike. It’s that simple. Bullish confirmation: a green (up) day on the daily chart where volume noticeably expands relative to the recent thin bars — that would signal real buying stepping in, not just sellers stepping back.

$AMPX The Gauntlet II winners are now known. This is where things get interesting for AMPX: Amprius has already confirmed that roughly half of the 19 finalists use its cells. Several winners also have connections to the UMAC/Upgrade Energy ecosystem, and Upgrade Energy is an official Amprius partner. Now we’re waiting for the actual production orders and confirmation of which batteries are being used. If multiple winners are indeed producing with Amprius cells, Gauntlet II could become a meaningful additional revenue driver for AMPX.

$AMPX I was holding miserably Sofi and palantir for years then missed the big gains by selling too early. Locked in some profit ofc but didn't have enough patience. Lesson learnt. Holding tight LFG !!!

$AMPX Best remedy against stock manipulation (and there is some here as well) is for the company to execute. Develop new products (like today's PR) grow customers, sales etc. Once that catches up with the stock price, little shorts thinking they can play the game forever in and out, will be betting on the wrong day soon. Because once momentum turns with a stock that's been held down long enough, the move up usually is quick and violent. And the wheels are already in motion. Every PR like today's, brings that possibility closer.

$AMPX I miss the excitement and riding that high all the way up. $20's were pretty, portfolio was fat, and moral was boosted. Now its dry and dragging ass these days...😆...Still not selling till $85-$100. Suck it MM's and bears.

$AMPX Well any number of things can make the SP move. but IMO only a solid order/ deal will keep this above $9 for foreseeable future. If it bumps for Any other reason, the rise will be a temporary one. Market doesn’t have much appetite for speculation right now, and the MC is already too big for the little rev they have! Their profit margins will be a question mark as well.

$AMPX One factor that may be underestimated with $AMPX is the Russell Index effect. Since AMPX was removed from the Russell indices in June, part of the automatic demand from ETFs and passive funds has disappeared. Since then, we've seen noticeably low volume, little sustained buying pressure, and the stock stuck around $9–10. Now it gets interesting: Russell has moved to twice-yearly U.S. index reconstitutions in 2026. The next key Rank Day is October 30, with the first preliminary lists released on November 13 and the changes taking effect in December. If AMPX gets included again, index-tracking funds would need to add the stock back to their portfolios. With today's low trading volume, that additional demand could have a noticeable impact. No guarantee of a rally, of course, but definitely something worth watching.

$AMPX Part 1: Amprius has already shown how much FOMO can push valuation ahead of revenue. But underneath the volatility, the business itself has only become more convincing. I’ve followed Amprius for years. Kang Sun struck me as an unusually skilled and honest technology CEO, and Tom Stepien increasingly looks like the right leader for commercialization: broader market outreach, stronger visibility, more aggressive customer development, while still preserving what has felt like an “under-promise, over-deliver” culture. The toll-manufacturing strategy may prove especially powerful: far less capex, multiple suppliers competing on production economics, production closer to customers, and additional partners expected in the US and Europe. That matters when so much demand is international. 🚀

$AMPX Don't let these candy ass losers get your shares ;^) Many markets need these batteries with society in general going mobile. I'm hangin' as long as it takes.

$AMPX I am now down as much as I was up on this stock. It's hard to watch. Tough hold for sure. I still believe, I keep going back to why I bought in the first place. Unless there is something going on that us retail are not aware of the story still holds. So hold it is !!!

$AMPX The latest Gauntlet II results look promising for AMPX investors. The top performers have been announced, with roughly 60,000 drones expected to be procured. ModalAI, which publicly documents the use of Amprius cells, made the top five in Close Quarters Battle. Amprius previously stated that roughly half of the 19 participants were using its cells. Now the key question is how many winning platforms using Amprius will receive orders. Names, quantities and contracts – that’s what matters next for AMPX.

$AMPX When I bought into AMPX in ’24 I was thinking it could potentially reach a 1 billion market cap by 2027 based on its earnings projections. Then it absurdly skyrocketed to a 4 billion dollar market cap in under a year. Now, due to market conditions (i.e. our retarded President), it’s ”fallen” to a mere 1.3 billion dollar market cap. I think this company is extremely well positioned and they likely will organically reach a 5-10 billion market cap in the next few years. But people acting so shocked that the share price has returned to reality is so dumb. They still haven’t reached positive EPS and they were trading at 50x p/s at $24. Like, cmon yall. That’s not sustainable lol

$AMPX With short volume persistently near 47%, the stock remains structurally vulnerable to a short squeeze. While shorts target AMPX on valuation, any surprise operational updates or clearing dark pool volume could cause bears to scramble, forcing rapid upside velocity from its current $9.63 base.
