Estimates, not targets. The DCF treats free cash flow as cash flow to equity and divides by shares (the common retail shortcut — it skips net debt and a full WACC), so it’s a sanity-check, not a valuation opinion. All inputs are from PACB’s SEC filings; change any assumption above and the numbers update live. Educational only — not investment advice.

From SEC Form 4 and 13F filings. Both are backward-looking disclosures on different reporting clocks, and neither predicts price. Educational information only — not investment advice.
This date was extracted directly from PACB's own Form 8-K (earnings press release) filed with the U.S. Securities and Exchange Commission — not an analyst estimate or a third-party calendar. We mark a report “confirmed” only when the company itself has stated the date in a public SEC filing, and we link that filing above so you can verify it. Everything else stays an honest estimate from the company's filing cadence. From filings, not guesses.
Projected from PACB's own SEC 8-K filing history — the year-over-year reporting pattern (about 47% land the exact day, about 91% within a week, measured across 4,713 past reports).
