With the share price around US$30.06 and trailing twelve month losses still sizeable, the story here is less about the top line and more about how margins and cash burn shape the risk and reward trade off in the periods ahead.

US$72.5m revenue, but US$36.5m loss on the year
- Over the last twelve months to Q4 FY 2025, Ambiq Micro generated US$72.5 million in revenue and reported a net loss of US$36.5 million, with basic EPS at a loss of US$4.57 on this basis.
- Consensus narrative talks up revenue growth of about 28.2% a year as a key upside. However, the latest trailing 12 month loss of US$36.5 million and guidance that analysts do not expect profits in the next three years show that higher sales alone have not yet translated into positive earnings.
- Analysts expecting revenue to reach US$152.0 million and earnings of US$22.3 million by around 2028 are effectively leaning on a margin swing from roughly a 49.9% loss to a 14.7% profit margin, while today the company is still firmly in loss making territory.
- With the current share price around US$30.06 and an analyst price target of US$38.75, you are being asked to weigh that hoped for margin shift against the reality of a US$36.5 million trailing loss and an EPS loss of US$4.57.
Premium 8.7x P/S while losses have grown 7.4% a year
- The stock trades at a P/S of 8.7x compared with a peer average of 3.1x and a US Semiconductor industry average of 6.0x, while losses have grown at about 7.4% a year over the past five years and forecasts still point to no profitability over the next three years.
- Bears focus on that mix of rich sales multiple and ongoing losses, arguing that paying 8.7x sales for a company expected to stay loss making for at least three more years leaves little room for missteps.
- On their numbers, earnings would need to rise from roughly a US$36.0 million loss today to US$24.3 million of profit by around 2029 to back a price target case, a swing of more than US$60 million in annual earnings even though the company is still reporting quarterly net losses of around US$8 million to US$11 million.
- Even in that bearish scenario, they assume Ambiq could trade on a 39.8x P/E multiple, which is still high in absolute terms and above many mature chip names, so anyone buying at US$30.06 today is exposed if that level of profitability or valuation does not eventuate.
25% revenue growth forecasts vs Q4 loss of US$10.7m
- In Q4 FY 2025, revenue of US$20.7 million came alongside a net loss excluding extra items of US$10.7 million, and forecasts still call for revenue to grow at about 25.1% a year even as the company is expected to stay unprofitable over the next three years.
- Bulls point to that roughly 25% forecast revenue growth as a key reason to look past current losses, arguing that demand for edge AI chips across wearables, medical devices and industrial sensors can support higher volumes and better gross margins over time.
- They highlight that if margins moved from roughly a 49.9% loss to the semiconductor industry average of 14.7%, earnings could reach about US$21.0 million by around 2028 compared with a trailing net loss of US$36.5 million today, a swing of more than US$50 million.
- Against a share price of US$30.06 and an analyst target of US$38.75, that view leans on the idea that mid double digit annual revenue growth combined with higher value Apollo and Atomic products can eventually narrow the gap between current quarterly losses of around US$9 million to US$11 million and the profit levels baked into those long term forecasts.
