Cranium Ventures acquisition closing • 2026-09-30

Base target: $50 / p=50% prob

Biggest risk

Q2 net new ARR bookings declined 25% year over year; Biller adjusted EBITDA fell 13%, and 2026 guidance relies heavily on Q4 license renewals. Cranium’s purchase price and integration economics are undisclosed. [#8-K-2026-08-06] SEC Exhibit 99.1 [#PR-ACI-2026-09-01] Company release

Invalidation

Break below $40 or thesis failure.

What would change my mind?

Q2 revenue rose 7% and adjusted EBITDA rose 12%; ACI signed two U.S. Connetic customers and subsequently announced the Solaris SEPA Instant go-live. These support platform adoption, but disclosed customer economics remain limited. [#8-K-2026-08-06] SEC Exhibit 99.1 [#PR-ACI-2026-09-24] Company release

Commentary

Recent company announcements are constructive, particularly Solaris’s live deployment, but their incremental revenue impact is unquantified. The September 25 anchor is $49.51; no reliable post-announcement price attribution or analyst revisions were established. The stored earnings-document row concerns MRVL, not ACIW, and was excluded. Social, options, short-interest and employee sentiment data are unavailable; zeros above denote unavailable data, not neutral measurements.

ACI raised 2026 revenue guidance to $1.895–$1.925 billion and adjusted EBITDA guidance to $545–$560 million, but expects Q4 to carry roughly 60% of second-half revenue because of high-margin Payment Software license-renewal timing.
