These releases collectively underscore a higher forward guidance and a surge in drone‑related battery orders, while also highlighting the company’s expanding presence in aerospace, defense, and EV markets.


Fundamentals and Valuation

The company’s financial profile reflects a classic high‑growth, low‑profitability dynamic typical of emerging‑technology firms that are still scaling production.

Revenue and Margin Trajectory

Amprius’s revenue base has expanded dramatically over the past six years. In 2020, the company reported $4.68 M in sales, which grew to $27.72 M in 2021—a 492 % jump. The upward trend continued, reaching $44.09 M in 2022, $87.91 M in 2023, and a striking $241.67 M in 2024. The most recent fiscal year, 2025, closed with $730.11 M in revenue, representing a 202 % increase from the prior year and a cumulative 15,500 % growth since 2020.

Margins have been volatile as the firm invested heavily in new production lines and R&D. Gross margins were deeply negative in the early period (‑43.09 % in 2020) but turned positive at 11.32 % by the end of 2025. Operating margins improved from a low of ‑440.3 % in 2023 to ‑63.89 % in 2025, while net margins narrowed from ‑418.3 % to ‑60.30 % over the same span. The latest quarter’s 22.25 % gross margin suggests the company is beginning to capture economies of scale, a key inflection point for future profitability.

Cash Flow and Capital Structure

Free‑cash‑flow (FCF) remains negative, with a ‑$35.53 M figure for 2025, translating to a ‑3.48 % FCF yield. The company’s capital structure is leveraged, reflected in a Debt‑to‑Equity ratio of 5.08 and an interest coverage metric that is effectively infinite (interest coverage not disclosed, but the “Int cov” figure of 999.0 indicates ample coverage under LOPJLB’s internal calculation). The high Altman Z‑Score of 41.87 signals strong solvency despite the heavy debt load, largely because the model incorporates the firm’s rapid revenue expansion.

Valuation Perspective

The trailing P/E of –40.76 underscores that earnings are currently negative, while the forward P/E of 219.9 reflects analysts’ expectations of a future earnings turnaround. The PEG ratio of 1.91 suggests that, after accounting for the extraordinary revenue growth rate (143.6 % YoY), the stock may still be modestly overvalued relative to peers, but the high growth premium is baked into the price. The price‑to‑book multiple of 13.53 aligns with other high‑tech industrial firms that command premium valuations based on proprietary technology pipelines.

Overall, the valuation snapshot paints a picture of a growth‑oriented compounder that investors are pricing for future earnings rather than current cash profitability.


ETF Ownership

Amprius’s institutional exposure is concentrated among a handful of thematic ETFs that focus on clean‑energy, advanced materials, and autonomous‑vehicle technologies. The eight largest holders collectively own roughly 8 % of the float, with the top positions listed below.

ETFWeight
WAR (iShares MSCI World Energy ETF)2.04 %
ACES (VanEck Vectors Alternative Energy ETF)1.59 %
CTEC (ProShares UltraShort Technology)1.25 %
IDRV (iShares Self‑Driving Car ETF)0.67 %
QCLN (First Trust NASDAQ Clean Edge Green Energy Index Fund)0.49 %
FDRV (First Trust Nasdaq Transportation ETF)0.48 %
DRNZ (Direxion Daily Renewable Energy Bull 3X Shares)0.37 %
IBAT (ETFMG Prime Mobile Payments ETF)0.31 %

The concentration of ownership within a small set of sector‑specific ETFs can amplify price movements when those funds rebalance or adjust sector allocations. For growth‑oriented investors, the presence of WAR and ACES signals that the broader clean‑energy community is tracking Amprius as a strategic battery‑technology play.
