Thoma Bravo Advantage

admitted from the HISTORICAL census (EDGAR's SIC 6770 registrant list, walked in full: 3,325 registrants, 1,167 of which ever priced an IPO). The live discovery job cannot reach this registrant — it reads the filing tape, and this one stopped filing. Admission rule: src/lib/universe-admit.ts. SIC 6770 (Blank Checks); 424B 0001193125-21-010142 priced 2021-01-15; common ticker TBA off 8-K 0001193125-21-202203 (2021-06-28); lifecycle EXITED. Ending PROVEN, not inferred: CLOSED per Form 25 0000876661-21-000968 (2021-06-29) — Form 25 filed under 17 CFR 240.12d2-2(a)(3) — the rule for securities that "have come to evidence other securities in substitution therefor", i.e. the shares became the successor's (class: Class A Ordinary Shares);

the successor named here was WRONG and is withdrawn — was: "the successor registrant SolarWinds Corp (SWI) (CIK 0001739942) filed an 8-K carrying item 2.01 (Completion of Acquisition) naming "Thoma Bravo Advantage" — the SPAC merged into a new registrant and so filed no closing report of its own". ipoSizeM and deadline left NULL: gross-proceeds prose conflates the over-allotment with the offering, and a charter deadline belonging to a vehicle that has ended is a date nobody can act on. ipoDate is the 424B pricing date.

Thoma Bravo Advantage combined with ironSource Ltd (CIK 0001837430), not with SolarWinds Corp. TBA filed its own closing report: 8-K acc 0001193125-21-202203 (filed 2021-06-28, items 1.02/2.01/3.01/3.03/5.01/5.02/8.01/9.01) states that on June 28, 2021 Showtime Cayman merged with and into TBA and the surviving entity then merged into Showtime Cayman II, both wholly-owned subsidiaries of ironSource Ltd. The other side of the same closing is ironSource's 6-K acc 0001193125-21-203348 (filed 2021-06-29), which names "Thoma Bravo Advantage"; ironSource listed on the NYSE as IS by 8-A12B acc 0001193125-21-198097 (2021-06-24). ironSource is a foreign private issuer and reports on 6-K/20-F, which is why a check that looks only for an 8-K from the successor could not have confirmed it either. How the wrong name arrived: findSuccessor8K (scripts/_uni3/lib.mts) full-text-searched the phrase "Thoma Bravo Advantage" in 8-Ks, excluded the SPAC's own CIK — discarding the real closing 8-K, which is the top hit — and took the earliest remaining item-2.01 filer, SolarWinds Corp's 8-K acc 0001628280-21-014064 (2021-07-20, the N-able separation). The phrase appears once in that whole submission, in a director biography in the N-able information statement (exhibit 99.1): "Cam McMartin currently serves as a board member and a company and fund advisor of Thoma Bravo Advantage." Status is untouched: CLOSED still rests on Form 25 acc 0000876661-21-000968 (2021-06-29) under Rule 12d2-2(a)(3).

[CLOSED-2.01] SEC accession 0001193125-21-202203 (Form 8-K, item 2.01 Completion of Acquisition or Disposition of Assets); the cover's date of earliest event reported is 2021-06-28. That is the SEC's own date for this report and NOT necessarily the closing day — an 8-K may cover several events, and where the two differ the closing date is in the quoted sentence below. Target read STRUCTURALLY from the merger agreement's party list — the party that is neither the registrant (identified by the filing's own cover page) nor a merger sub (identified by the clause making it a subsidiary of another party) nor an accommodation party (identified by a "solely for purposes of" joinder), and it was the only one left. The sentence it was read from: "As previously disclosed, on March 20, 2021, Thoma Bravo Advantage (“ TBA ”) entered into an Agreement and Plan of Merger (the “ Merger Agreement ”), by and among TBA, ironSource Ltd., a company organized under the laws of the State of Israel (the “ Company ” or “ ironSource ”), Showtime Cayman, a Cayman Islands exempted company and wholly-owned subsidiary of the Company (“ Merger Sub ”), and Showtime Cayman II, a Cayman Islands exempted company and wholly-owned subsidiary of the Company (“ Merger Sub II ”)." No deal value is set — an item-2.01 heading is not a figure. No date column is set: Deal has announcedAt, voteDate and expectedCloseAt and nowhere to record an actual close, so the SEC's date is kept here until that column exists.
