ACI Worldwide (ACIW) Stock Looks Cheap On Cash Flow While Earnings Look Fair

Listen to the news

ACI Worldwide stock has surged over the past three years, yet the valuation picture is mixed, with the intrinsic value estimate from a Discounted Cash Flow (DCF) model suggesting the shares trade below that estimate while the broader checks still do not flag the stock as a clear bargain.

  • ACI Worldwide has returned 150.3% over the past three years, which puts extra focus on whether the current price still leaves room above intrinsic value or mainly reflects past gains.
  • Recent news highlighting a sharp share price run and a higher market capitalization can support sentiment, but the underlying operating and financial profile may still limit how much investors are willing to pay for future cash flows.
  • With the stock screening as undervalued in 2 of 6 checks, the overall valuation score is low. This suggests that, despite the supportive DCF read, ACI Worldwide does not screen as an obvious bargain on the broader measures used in the valuation summary.

The issue now is whether ACI Worldwide's recent share price strength already reflects most of its intrinsic value, or if the Discounted Cash Flow estimate implying around 17.2% undervaluation still points to meaningful upside from here.

ACI Worldwide delivered 28.1% returns over the last year. See how this stacks up to the rest of the Software industry.

Does ACI Worldwide Look Undervalued on Cash Flow?

The Discounted Cash Flow (DCF) approach here focuses on the cash ACI Worldwide is expected to generate for shareholders over time. The model starts from latest twelve month free cash flow of about $265 million and applies a growing cash flow path, which is typical for a mature but still expanding software business.

On these assumptions, the DCF model arrives at an estimated intrinsic value of about $70 per share, which implies the stock trades at roughly a 17.2% discount to that estimate. The recent 9 day share price surge that lifted ACI Worldwide's market value to about $5.7b has narrowed the gap, but the model still points to the market valuing the stock below its projected cash flows.

Overall, the DCF work suggests ACI Worldwide stock currently appears undervalued relative to its estimated intrinsic value.

Our Discounted Cash Flow (DCF) analysis suggests ACI Worldwide is undervalued by 17.2%. Track this in your watchlist or portfolio, or discover 47 more high quality undervalued stocks.

Where Does ACI Worldwide Sit on Earnings?

The P/E ratio suits ACI Worldwide because earnings are a core driver for established software and payments companies. ACI Worldwide currently trades on a P/E of about 28.6x, which is very close to the broader software sector average of roughly 28.6x and sits above the peer group average of about 14.8x.

The tailored fair P/E ratio for ACI Worldwide, which reflects its specific growth profile, margins, size and risk, is estimated at about 27.1x. That is only slightly below the current multiple, so the stock does not screen as materially cheap or expensive on earnings compared with what this framework suggests investors might typically pay.

Overall, ACI Worldwide appears roughly fairly valued based on its P/E multiple.

The Bottom Line

For ACI Worldwide, the Discounted Cash Flow (DCF) work points to intrinsic value above the current share price, while the P/E view suggests the stock trades close to what peers and its own profile might justify. That tension, combined with weak broader valuation checks, means the apparent DCF discount is not backed up across all lenses. From here, the key question is whether ACI Worldwide can deliver the cash flow path implied in the DCF without investors marking down the earnings multiple. The answer to that will determine whether the current discount is an opportunity or simply reflects justified caution.
