Complete event summary combining all related documents: earnings call transcript, report, and slide presentation.Executive summary
Achieved first 5G product revenue in Q3 2025, marking a key milestone in commercialization and the start of a planned sales ramp, with strong early demand and over 2,500 chipset orders.
Successfully completed 5G chipset and module sampling with lead customers, including Airspan Networks and Orbic, receiving positive feedback and validation.
Gogo is set to be the first 5G network operator to activate full service using the company's chipset before year-end 2025, following successful field testing.
Specializes in fabless semiconductor design and sales, focusing on 4G/5G wireless chipsets for industrial, B2B, and consumer applications, with global operations and R&D in South Korea.
Continues to experience significant operating losses and negative cash flows, with ongoing dependence on external financing and related party loans.
Financial highlights
Net revenues for Q3 2025 were $0.4 million, down 84% from $2.6 million in Q3 2024, mainly due to a $1.6 million decrease in product sales.
Gross margin for Q3 2025 was negative due to insufficient product revenue to absorb overhead, compared to 62% in Q3 2024.
Net loss for Q3 2025 was $13.8 million, compared to $7.1 million in Q3 2024; nine-month net loss was $34.4 million.
R&D expenses decreased by $1 million to $3.3 million, mainly due to lower professional services after 5G chip design completion.
Cash and cash equivalents stood at $8.3 million as of September 30, 2025.
Outlook and guidance
Margins expected to improve substantially as 5G product sales ramp up, with significant contribution anticipated from Q1 2026.
Expects commercial 5G product shipments to begin late Q4 2025 or early Q1 2026, with break-even adjusted EBITDA targeted for Q3 2026 and positive operational cash flow in Q4 2026.
Ongoing need for additional capital to fund operations and meet debt obligations; substantial doubt exists about ability to continue as a going concern without new financing.
Focus remains on scaling production, aligning supply chain, and supporting customer launches into 2026.
Plans to expand product lineup for future 5G applications, including automotive and IoT.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.
One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
This is genuinely one of the cleanest and fastest finance apps out there to track the market.
