Resolution criterion
Yes if Cintas Corporation and/or UniFirst Corporation announce, by press release or SEC filing, that the acquisition of UniFirst by Cintas has been completed (the merger has become effective and closing has occurred) on or before 31 December 2026. An announcement of a regulatory clearance, a shareholder approval or an expected closing date, without the completion itself, does not count. No completion announced by that date, or a termination of the merger agreement, resolves No.
Verified starting state
UniFirst press release of 21 October 2026 (SEC Form 8-K, Exhibit 99): the transaction is "expected to close prior to the end of calendar year 2026", subject to customary closing conditions and required regulatory approvals. On 2 October 2026 both companies certified substantial compliance with the U.S. FTC Second Request and entered a timing agreement under which they will not close before 11 December 2026, unless the FTC first notifies them in writing that it has closed its investigation. Both companies certified on 29 September 2026 that they had completed their responses to the Canadian Competition Bureau's Supplementary Information Request (issued 2 July 2026). The release does not state an outside date. No base rate has been computed for this question; the rate used will be a guessed one. The check is manual (press release or SEC filing).
What pushes it up
- UniFirst and Cintas announced in October 2026 that they still expect the transaction to close prior to the end of calendar year 2026 [tier 1].
- Both companies have completed responses to Canadian competition authorities and certified substantial compliance with FTC second requests [tier 1].
What pushes it down
- Reuters reported that the FTC plans to sue to block the $5.5 billion deal, which would push any potential resolution well past the December 31, 2026 deadline [tier 2].
- Under the FTC timing agreement, the parties cannot close before 11 December 2026, leaving a narrow 20-day window for regulatory clearance and closing before year-end [tier 1].
What would move this number most
Whether the FTC files a lawsuit to block the deal before December 11, 2026, or reaches a settlement/clearance that permits closing in late December.
