For a stock down 49% since late September, the December print decides whether flat margin is a one-quarter price or a structural squeeze. ## A beat above the ceiling [Ambiq Micro](https://theinference.org/markets/companies/ambiq-micro), the Austin chipmaker whose ultra-low-power processors run AI on batteries in watches, rings and sensors, [reported September-quarter net sales of $38.1 million on November 10](https://www.sec.gov/Archives/edgar/data/1500412/000119312526454445/0001193125-26-454445-index.htm), up 110% year over year and 12.5% from June [1][2]. That beat the top of the $36–37 million range finance chief Jeff Winzeler set on August 11, when management said tight capacity "across wafers, packaging, substrates, and testing" constrained the second half [3]. The Street wanted $36.7 million in sales and, on the informal whisper, a loss of $0.10 a share; Ambiq printed a $0.05 non-GAAP loss per share [4]. Chief executive [Fumihide Esaka](https://theinference.org/markets/people/fumihide-esaka) now credits supply-chain partnerships that "enabled us to secure capacity," and seven customers spent more than $1 million each, against three a year earlier [1]. *Chart: **December guidance puts Ambiq's sales above any quarter in its history** Column chart of Ambiq Micro quarterly net sales from Q1 2024 through Q3 2026 reported, plus Q4 2026 guided at the midpoint, in millions of dollars* *Quarterly net sales, $ millions; December 2026 shown at the guided midpoint, marked as an estimate. Sources: Ambiq SEC filings; Q3 2026 press release. [1][8]* ## The margin pays for the capacity The December guide steps sales up 14–17% to $43.5–44.5 million, and the bill lands in the margin line [1]. Non-GAAP gross margin is guided "approximately flat" to the third quarter because manufacturing efficiencies must offset what Ambiq calls "increased supply chain cost pressure" [1]. Operating expense rises to $25.5–26.5 million on Atomiq110 and Apollo340 tape-out costs, and the guided $0.03 to $0.09 loss a share on 24.6 million shares works out to $0.7 million to $2.2 million, against the $1.2 million non-GAAP loss just reported [1]. Sales doubled, and the leverage went back to the suppliers. Winzeler called a profitability date "too early" to name in August [3]. ## The market voted before the print Shares fell 49%, from $68.92 on September 24 to $35.22 on November 5, and [UBS cut its target to $50 from $73 on November 2, keeping Neutral](https://www.marketscreener.com/news/ubs-cuts-price-target-on-ambiq-micro-to-50-from-73-keeps-neutral-rating-ce785fd9d889f726) [5][6]. Insiders filed about $6.5 million of sales between September 16 and October 16, [sales The Inference reported on October 26](https://www.theinference.ai/article/ambiq-micro-s-singapore-listing-sold-no-shares-three-executives-sold-stock-before-november-10) [5][7]. Esaka answers with a multi-year edge-AI demand shift, $363.5 million of cash and no debt [1][3]. At the guide's midpoint, 2026 lands near $141 million, above the roughly $135 million management sketched in August while calling supply the binding constraint [1][3]. December's gross margin settles the argument: flat means the capacity was bought at a one-quarter price, lower means the squeeze is structural. ## Takeaway Ambiq doubled sales and beat its supply-capped guide, but flat guided gross margin and a wider guided loss leave the December print to settle whether the capacity squeeze is a one-quarter price or structural. ## Sources 1.
