Tanium's own releases support six exact disclosed financings totaling $712M in this source-backed subset, but not the imported Series J/I/H/G/F/E/D/C/B labels. The January 2021 $150M sale was completed common stock to Ontario Teachers; a separate 2020 Form D reports $150,499,974 of equity securities sold in an offering, not net issuer proceeds or a completed $200M target. Original 2009, 2010 and 2011 SEC notices add three earlier equity-offering observations, not authenticated net new capital. Amendments replace earlier sold-to-date observations within the same offering; targets and unsold balances are not additional proceeds. Related-person listings are not subscriber lists. Salesforce confirms an earlier June 2020 strategic financing but not its amount. The reported May 2018 $175M TPG transaction included employee-share purchases, so no exact new-company-capital component is inferred. The 2007 $2M claim remains database-only. Issuer release dates, filing publication dates, Form D first-sale dates and reported transaction dates are distinct; this is not a complete legal financing register or current cap table. SEC publication does not mean the filing was verified by the SEC. The old latest-round article's Series J label is withheld from this company ledger pending editorial review.
