Every figure is extracted from ESS Tech, Inc.’s annual reports as filed with the SEC (XBRL company facts) — no third-party estimates. Fiscal years are labeled by period end; filers occasionally re-tag concepts, so a sparse cell means the company didn’t report that concept for that year. Free cash flow = operating cash flow − capital expenditures.
Research and education only — not financial advice. TENKis not a registered investment adviser or broker-dealer and gives no personalized advice. Every call is impersonal — identical for all users, generated on a schedule from SEC filings plus a delayed/third-party price feed — may be wrong or out of date, and is not a recommendation to buy or sell any security. The operator and an affiliated trading operation may hold or trade the securities TENK rates; see Disclosures. Past performance does not guarantee future results. Do your own research.
