Shares of AmpliTech Group Inc. (NASDAQ: AMPG) skyrocketed 26.8% on Monday, closing at $6.57 after the company announced that its 64T64R massive-MIMO radio was the only device in that configuration tested at the O-RAN Alliance Global PlugFest Spring 2026. The event, held from February to May, evaluates interoperability among equipment from various vendors, a key step for open radio access network (Open-RAN) adoption.
The stock hit an intraday high of $7.18, with trading volume surging to approximately 9.9 million shares, propelling the company's market capitalization to roughly $159.5 million. After-hours trading saw the stock edge up to $7.025 as of 6:01 PM EDT. The rally came amid a broader rebound in technology and chip stocks, which recovered from last week's steep selloff, providing a favorable backdrop for smaller hardware names.
Open-RAN architecture allows mobile network operators to mix and match equipment from multiple suppliers rather than relying on a single vendor's proprietary stack. This approach aims to reduce costs and increase flexibility in building and upgrading mobile networks. AmpliTech's radio was tested in live, structured environments alongside major carriers including AT&T, Deutsche Telekom, Korea Telecom, LG Uplus, Orange, and Rakuten Mobile. Despite the milestone, the company did not announce any purchase orders or provide revenue guidance from the PlugFest.
Massive MIMO (multiple-input, multiple-output) technology uses a large number of antennas to steer signals more precisely, enhancing coverage and network capacity. The "64T64R" designation indicates the unit has 64 transmit and 64 receive antennas, making it suitable for high-capacity, dense 5G deployments. Founder, Chairman, and CEO Fawad Maqbool stated that the test proves Open-RAN interoperability is "real, not theoretical," positioning AmpliTech as a viable contender in the ecosystem.
The O-RAN Alliance reported that its spring PlugFest involved 31 companies and institutions across nine labs. Brian Daly, co-chair of the O-RAN Technical Steering Committee and an executive at AT&T Services, noted that such events help manage the "complexity of disaggregated network solutions." The broader Open-RAN market is attracting major players like Nokia and Ericsson, who are competing for contracts with large carriers such as Deutsche Telekom, AT&T, and MasOrange, aiming to lower costs by diversifying equipment sources.
AmpliTech, based in Hauppauge, New York, manufactures radio-frequency and microwave components, low-noise amplifiers, and 5G infrastructure for telecom, satellite, defense, space, and quantum computing applications. The company's first-quarter results provided additional momentum: sales surged 48.6% to $5.35 million, and gross margin improved to 47.98% from 33.00% a year earlier. Management attributed the growth to increased demand for 5G products.
However, the rally is not without risk. The PlugFest validates technical capability but does not generate immediate revenue. AmpliTech reported a net loss of $1.52 million for the quarter and burned $3.14 million in cash from operations. The company also disclosed material weaknesses in its internal control over financial reporting. Additionally, it listed 12.86 million potential common shares from options, warrants, rights, and restricted stock units that were excluded from diluted earnings per share due to the net loss.
The stock's next catalyst will be whether this technical achievement translates into concrete customer orders, deployments, or improved revenue visibility. Until then, the surge remains a bet on future potential rather than current financial results.
