AmpliTech Group Inc. shares rose Monday. The company said its 64T64R massive-MIMO radio was the only radio in that configuration to be tested at the O-RAN Alliance Global PlugFest Spring 2026. The event is used to test if gear from various suppliers is compatible.
The Nasdaq stock finished the session at $6.57, up 26.8%, after hitting a high of $7.18. Volume reached roughly 9.9 million shares, and the company’s value was about $159.5 million at the close. After-hours, the quote moved to $7.025 at 6:01 p.m. EDT.
The timing was a factor. Tech and chip stocks were rebounding from last week’s steep selloff, so the move back in helped smaller hardware stocks. They had a firmer tape to rally on.
Open RAN — open radio access network — is designed so carriers can use gear from different vendors instead of a single supplier’s stack. The aim is to open up the mobile network plumbing, making it less tied to one vendor.
AmpliTech said its O-RAN CAT B 64T64R Massive MIMO radio got tested in live, structured settings with operators like AT&T, Deutsche Telekom, Korea Telecom, LG Uplus, Orange and Rakuten Mobile. Still, the company didn’t report any purchase order or give a dollar amount from the PlugFest.
Massive MIMO stands for multiple-input, multiple-output. It’s a type of radio system using many antennas to direct signals better, which can boost coverage and network capacity. The term “64T64R” means the unit has 64 transmit and 64 receive antennas, a setup aimed at high-capacity, dense 5G networks. ericsson.com
AmpliTech was the sole 64T64R radio at the event, founder, chairman and CEO Fawad Maqbool said in a statement. Maqbool said the test proved Open RAN interoperability is “real, not theoretical.” GlobeNewswire
O-RAN Alliance reported its spring PlugFest ran from February to May with participation from 31 companies and institutions at nine labs. Brian Daly, who is both co-chair of the O-RAN Technical Steering Committee and an executive at AT&T Services, said PlugFests can help handle the “complexity of disaggregated network solutions.”
This is what’s at stake. Big network equipment makers like Nokia and Ericsson are going after Open RAN contracts with large carriers such as Deutsche Telekom, AT&T, and MasOrange. The tech is supposed to cut costs for carriers by opening up equipment from multiple vendors.
AmpliTech wants to turn the opening into a business line. The Hauppauge, New York outfit makes radio-frequency and microwave parts, low-noise amplifiers, and 5G infrastructure aimed at telecom, satellite, defense, space, and quantum computing customers.
The company’s new quarterly numbers gave bulls new ammo. First quarter sales jumped 48.6% to $5.35 million, while gross margin increased to 47.98%, up from 33.00%. Management said the bulk of the sales growth was driven by more demand for 5G products.
But the risk is clear. A PlugFest checks the tech, but brings in no money. AmpliTech posted a $1.52 million net loss for the quarter and burned $3.14 million cash from operations. It also disclosed that its internal control over financial reporting was not effective, citing material weaknesses. In the same filing, AmpliTech listed 12.86 million possible common shares from options, warrants, rights and RSUs that weren’t included in diluted EPS since the company lost money.
The next hurdle for the stock is if the technical win on Monday turns into real customer orders, deployments or more solid revenue visibility. Without those, AmpliTech’s rally still bets on potential, not results.
