• ACI Worldwide is reportedly weighing a sale of its Biller segment at a roughly $1.5 billion valuation, per Reuters, citing three unnamed origins.
• The price tag implies a 10-to-12-times multiple on the segment's 2025 adjusted EBITDA of $141 million against $818 million of revenue.
• Prospective buyers reportedly include private equity firms; ACI is working with investment bankers, and discussions are described as preliminary.
• A divestiture would leave ACI concentrated on its combined bank-and-merchant payments segment, which the company merged into a single reporting line in 2025.
• Nothing is confirmed: ACI Worldwide has not publicly acknowledged a sale process, and reported talks may not produce a transaction.

ACI Worldwide is reportedly weighing a sale of its Biller segment at a roughly $1.5 billion valuation, Reuters reported July 17, 2026, citing three people familiar with the matter. The price implies a 10-to-12-times multiple on the segment's 2025 adjusted EBITDA of $141 million, against $818 million of revenue. ACI is said to be working with investment bankers and has held early conversations with prospective buyers, including private equity firms. The talks are preliminary; ACI Worldwide has not confirmed a transaction, and the outcome remains uncertain until the company or a buyer discloses terms directly.

The Math Behind $1.5 Billion

The reported $1.5 billion price implies roughly a 10-to-12-times multiple on the Biller segment's 2025 adjusted EBITDA of $141 million, according to the figures cited in reporting on the process. The segment generated about $818 million in revenue over the same period. That multiple sits at the higher end of recent payments-software deals, reflecting the segment's recurring, contract-based revenue base rather than transaction volume that swings with consumer spending.

What the Biller Segment Does

ACI Worldwide's Biller segment supplies electronic billing and digital payment-collection technology to government agencies, healthcare payers, insurers, telecom providers and utilities. Reported client relationships include the Internal Revenue Service (IRS) and regional Blue Cross Blue Shield affiliates, according to accounts of the sale process. The unit is billed as a separate reporting segment from ACI's payments business, giving a prospective buyer a discrete, carve-out-ready set of contracts and revenue rather than a blended business line.

Why Now

Reuters attributed dealmaking interest in the sector to strong investor demand for payments software and recurring-revenue businesses. A sale would also follow ACI Worldwide's 2025 decision to merge its previously separate banking and merchant-payments segments into a single reporting line, leaving the Biller segment as its remaining standalone unit. Divesting it would let ACI concentrate capital and management attention on that combined payments business — a rationale consistent with, but not confirmed by, the company itself.

What This Means for the Market

For fintech and payments buyers, the reported process signals that recurring-revenue billing infrastructure — the unglamorous plumbing behind utility, healthcare and government bill collection — is drawing double-digit EBITDA multiples from private equity. For ACI Worldwide shareholders and counterparties, the takeaway is caution: talks are preliminary, sourced anonymously, and may not close. Watch for an ACI regulatory filing, an 8-K, or a direct company statement as the next confirming signal, not further anonymously sourced reporting.
