Amprius Technologies posted record Q1 2026 revenue of $28.5 million, up 153% year over year, and raised its full-year revenue outlook to at least $130 million from at least $125 million.
The company said demand is being driven by its SiCore silicon-anode batteries, with strong adoption in unmanned aerial systems, defense, and light electric vehicles; it also highlighted a $21 million purchase order from a China-based LEV customer and expanding U.S. traction.
Amprius ended the quarter with $62.4 million in cash and no debt, while also moving to simplify its capital structure through a warrant exchange that could avoid at least $70 million of dilution.
Amprius Technologies Ups the Voltage on Forward Outlook
Amprius Technologies (NYSE:AMPX) reported record first-quarter 2026 revenue and raised its full-year sales outlook, citing expanding adoption of its silicon-anode batteries across unmanned aerial systems, light electric vehicles and defense-related applications.
Chief Executive Officer Tom Stepien said the company generated first-quarter revenue of $28.5 million, up 153% year over year and 13% sequentially. Chief Financial Officer Ricardo Rodriguez said the results gave Amprius confidence to lift its 2026 revenue forecast to at least $130 million, up from a prior baseline of at least $125 million.
“Our second generation SiCore silicon anode batteries are gaining broad adoption across unmanned aerial system customers, and we are pleased to see the momentum we have built in Europe is now taking hold in the United States,” Stepien said.
SiCore Drives Product Mix as SiMaxx Winds Down
Rodriguez said SiCore represented 97% of product revenue in the quarter, continuing Amprius’ shift away from its legacy SiMaxx platform. Revenue by geography was 58% from Europe, the Middle East and Africa, 21% from North America and 21% from Asia Pacific. He said the North American share increased “meaningfully” both sequentially and year over year, reflecting growing interest from U.S.-based customers.
2 Stocks With Governmental Tailwinds to Drive Them Higher
Gross profit was $5.7 million, resulting in a 20% gross margin, down from 24% in the fourth quarter. Rodriguez attributed the decline largely to overhead tied to the Fremont facility as SiMaxx winds down. He said SiMaxx-related overhead costs were more than $3 million against only $618,000 of revenue, creating a “material but temporary drag” on blended margin. Excluding one month of Colorado expenses, gross margin would have been 22%, he said.
Operating expenses totaled $12.4 million, including $3.8 million in research and development and $8.6 million in selling, general and administrative expenses. The company reported an operating loss of $6.7 million, adjusted EBITDA of negative $1.8 million and a GAAP net loss of $5 million, or $0.04 per share, based on approximately 136.9 million weighted average shares outstanding.
Amprius ended the quarter with $62.4 million in cash and no debt. Rodriguez said cash declined from $90.5 million at year-end due in part to an $11.5 million increase in accounts receivable and an approximately $20 million payment to settle the Colorado facility lease obligation. He said that settlement resolved what would have been more than $110 million of expense “in highly favorable terms” and reduced liabilities by $29.8 million during the quarter.
Defense Customers and Light Electric Vehicles Highlight Demand
Stepien pointed to recent contract awards to three Amprius customers using SiCore batteries as indicators of future demand. He cited Kraus Hamdani Aerospace, whose K1000ULE unmanned aircraft is designed for 24-hour flight and a 1,000-mile range; AeroVironment, which won a $117 million U.S. Army contract for P550 UASs; and Teledyne FLIR, which announced a European order for its Black Hornet 4 nano drone.
“Their success boosts our visibility into future purchase orders for SiCore cells,” Stepien said.
The company also announced that its silicon-anode cells were selected by a China-based light electric vehicle customer, which placed a $21 million multi-quarter purchase order for batteries for two- and three-wheeled vehicles. Stepien said winning business in China was notable given the region’s concentration of major battery competitors.
Amprius’ work with the U.S. Defense Innovation Unit also expanded during the quarter. Stepien said a development contract first awarded in July 2025 was increased for a third time and now totals $18.1 million. The latest increase adds delivery of three types of silicon-anode cylindrical cells and four standard-size pouch cells.
Company Raises Revenue Guidance, Reaffirms EBITDA Outlook
Rodriguez said Amprius continues to see “healthy demand indicators,” including growing backlog, higher production volumes at manufacturing partners and increasing urgency from defense-related customers around NDAA-compliant supply.
For 2026, the company now expects:
Revenue of at least $130 million.
Adjusted EBITDA of at least $4 million.
A net loss of no more than $8 million, or less than $0.06 per share.
Capital expenditures below $10 million, expected to be funded by the Defense Innovation Unit contract.
Rodriguez said Amprius still sees a path to its 25% full-year gross margin target, with improvement expected mainly in the second half. He said factors include accelerating U.S. demand, managing the China and Asia Pacific mix, and improving logistics coordination as volumes scale.
Warrant Exchange Aims to Simplify Capital Structure
Amprius also announced an agreement to exchange more than 7 million public warrants held by institutional investors into common stock. Rodriguez said the company had nearly 16.5 million public warrants issued when it went public in 2022, with a strike price of $11.50.
Rodriguez said converting 7.1 million of those warrants into stock would save shareholders “at least $70 million of dilution” that otherwise could have occurred if the warrants were exercised. He also said the transaction could relieve short interest tied to institutional warrant hedging.
The warrant exchange follows other balance sheet actions, including closing the company’s at-the-market offering program and settling the Colorado lease obligation. Rodriguez said the company is looking for opportunities to “simplify the balance sheet and optimize the capital structure.”
Management Discusses Manufacturing, Robotics and Standardization
During the question-and-answer session, Stepien said Amprius is seeing growing interest tied to U.S. defense programs, including drone-related initiatives. Asked about how recent awards to customers could translate into Amprius orders, Rodriguez said batteries typically account for 5% to 15% of the bill of materials for unmanned aerial vehicles, depending on how advanced the platform is.
Stepien also discussed progress with Nanotech, a cylindrical cell provider in Chico, California. He said Nanotech had validated Amprius’ silicon-anode materials in a 21700 cell and achieved performance about 10% better than a comparable 6.6Ah cell, with a 6.8Ah cell capable of handling up to 20 amps.
On robotics, Stepien said the market remains early and did not contribute meaningful first-quarter revenue, but discussions are underway with companies in the U.S. and Asia. He said Amprius’ high energy density is especially relevant in unstructured environments where robots cannot easily recharge.
Stepien said Amprius is also working with roughly 40 battery pack companies in a given quarter, including six to 10 major volume providers. He described them as a “force multiplier” because they help integrate Amprius cells into customized packs for end customers.
Looking ahead, Stepien said the company is focused on higher energy density, sustained power, safety, reliability and meeting manufacturing and country-of-origin requirements. “We remain deeply bullish about the opportunities in front of us,” he said.

"The transition from legacy SiMaxx overhead to high-margin SiCore defense applications creates a clear path to positive EBITDA, provided the company manages its ballooning accounts receivable."
Amprius (AMPX) is hitting a critical inflection point where revenue scaling is finally outpacing legacy cleanup costs. The 153% YoY revenue growth, paired with a move to clean up the cap table by eliminating potential dilution from 7.1 million warrants, suggests management is aggressively positioning for institutional interest. While the 20% gross margin is currently pressured by SiMaxx wind-down costs, the path to 25% looks credible if they successfully pivot to higher-margin U.S. defense contracts. However, investors must monitor the $11.5 million jump in accounts receivable, which suggests they are extending credit to drive that revenue growth—a potential liquidity trap if their customers face supply chain delays.
The company is burning cash to buy revenue growth, and the reliance on a single $21 million China-based LEV order introduces significant geopolitical and concentration risk that could evaporate overnight.
"AMPX's revenue execution, defense funding, and dilution avoidance de-risk the $130M+ FY guide, setting up margin expansion to 25% H2 for profitability inflection."
AMPX delivered legitimate 153% YoY revenue growth to $28.5M on SiCore ramp (97% mix), with U.S. defense tailwinds via DIU's $18.1M contract funding < $10M capex and customer wins at AeroVironment/Teledyne FLIR signaling backlog conversion. Balance sheet fortified: $62M cash/no debt post-Colorado settlement (saved $110M+ liability), warrant exchange averts $70M dilution. Raised FY rev to $130M+ (implies ~357% YoY growth), EBITDA breakeven+, on 25% margin path H2. Niche high-density silicon anode edge in UAS/LEV unmatchable short-term by graphite peers. Risks: lumpy defense orders, China LEV mix (21% Asia rev). Bullish setup for 2H re-rating to 10x FY sales if execution holds.
Gross margins slipped to 20% on $3M+ SiMaxx overhead drag despite claims of 'temporary' fix, while $28M Q1 cash burn and rising AR highlight collections/manufacturing scale risks in a commoditizing battery sector dominated by low-cost giants.
"Revenue growth is real but margin recovery is the make-or-break test; if Q2 gross margin doesn't improve toward 22-23%, the 25% target is fantasy and the stock reprices lower despite topline beats."
Amprius shows genuine operational momentum: 153% YoY revenue growth, $21M China LEV order, expanding defense tailwinds via DIU contracts now at $18.1M, and a clean balance sheet ($62.4M cash, zero debt). The warrant exchange eliminates $70M of future dilution overhang. However, Q1 gross margin collapsed to 20% from 24%, with management attributing $3M+ to SiMaxx wind-down overhead—a 'temporary' drag they claim. The real test: can they hit 25% full-year gross margin as volumes scale? At current burn (~$6.7M operating loss quarterly), even with the DIU contract covering capex, they need revenue to accelerate materially or opex discipline to tighten. The $130M full-year guide is only a $5M raise from prior $125M, suggesting conservative guidance or demand uncertainty.
Gross margin compression despite 153% growth is a red flag, not a feature—if SiMaxx overhead truly vanishes, why didn't management pre-guide for a margin cliff? And $21M from one China customer in a sector flooded with BYD and CATL creates concentration risk; that customer could pivot to cheaper domestic alternatives in Q3.
"Without durable margin expansion and reliable backlog-to-cash conversion, a $130m 2026 revenue target may still not translate into sustainable profitability or a defensible equity value."
Amprius reported Q1 revenue of $28.5m (+153% YoY) and lifted 2026 revenue guidance to at least $130m, with SiCore now 97% of sales. However, gross margin slipped to 20% as SiMaxx wind-down costs drag blended margins, and operating losses persisted (-$6.7m). Cash declined to $62.4m from $90.5m due to higher accounts receivable and a $20m Colorado lease settlement, despite a warrant-exchange that could save at least $70m of dilution. The bear case hinges on execution risk, reliance on defense NDAA channels and a China LEV order, and the risk that margin improvement and backlog conversion do not materialize quickly enough to support profitability.
The strongest counterpoint is that the 2026 revenue target depends on uncertain defense demand and a China-based order, while the company remains unprofitable with ongoing cash burn; any delay or downturn in these tailwinds could exacerbate cash needs and force further dilution.
"A 10x sales multiple is unjustifiable for an unprofitable battery manufacturer facing significant margin compression and execution risks."
Grok’s 10x FY sales valuation target is dangerously optimistic. Applying such a multiple to a company with 20% gross margins and persistent quarterly cash burn of $6.7M ignores the reality of the battery manufacturing sector, where commoditization is the baseline. Even with defense tailwinds, Amprius is essentially a high-beta play on government procurement cycles. If the $130M revenue guidance misses, the lack of a clear path to positive free cash flow will trigger a massive valuation reset.
"$11.5M AR jump signals working capital trap accelerating cash burn beyond op losses."
Panel glosses over AR explosion: $11.5M increase equals 40% of Q1 revenue, fueling $28M cash burn despite op losses of just $6.7M. This isn't scaling—it's credit-driven growth masking DSO creep (>90 days?). In commoditized batteries, China LEV customers can delay payments indefinitely amid glut; without swift collections, $62M cash evaporates in 5-6 quarters, pre-breakeven.
"AR explosion is a symptom, not a diagnosis—the verdict depends on whether it reflects customer payment delays or natural timing from defense contract milestone billing."
Grok's DSO concern is valid but incomplete. $11.5M AR jump needs context: if DIU contracts front-load milestone payments, AR could reflect timing, not collections risk. However, Grok's 5-6 quarter cash runway math assumes zero revenue growth—the $130M guide implies Q2-Q4 revenue accelerates materially. The real question: does AR/revenue ratio normalize, or does it deteriorate further? Management silence on DSO is deafening.
"AR timing risk is real but not the only driver; the real test is whether NDAA-driven revenue and the China LEV order can deliver sustainable gross margins and profitable backlog."
Responding to Grok: AR jump could reflect timing from front-loaded DIU milestones rather than unpaid receivables, so it might not imply immediate collection stress. However, the single China LEV order creates a vulnerability: if DIU timing slips or capex cycles delay orders, cash burn worsens. The overlooked toggle is sensitivity of back-half revenue to NDAA funding cycles; even with AR normalization, profitability hinges on sustained margin expansion and backlog conversion, not just receivables.
Panelists agree on Amprius' strong revenue growth and clean balance sheet, but disagree on valuation, cash runway, and the sustainability of its growth. Bulls highlight defense tailwinds and potential margin expansion, while bears caution about cash burn, accounts receivable, and the risk of a valuation reset if guidance misses.
