Approach 1: ACI Worldwide Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model takes estimates of the cash a business could generate in the future and discounts those cash flows back to today to arrive at an estimated intrinsic value per share.

For ACI Worldwide, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month Free Cash Flow is about $283.1 million, and analysts provide explicit forecasts out to 2027, where Free Cash Flow is projected at $374.2 million. Beyond that, Simply Wall St extrapolates the company’s cash flows out to 2035, with discounted values supplied for each year in the 10 year projection window.

Pulling those discounted cash flows together, the DCF model arrives at an estimated intrinsic value of about $64.05 per share. Compared with a current share price around $43.50, this implies the stock trades at roughly a 32.1% discount to that intrinsic value. On this DCF view, ACI Worldwide appears to be undervalued.

Approach 2: ACI Worldwide Price vs Earnings

For a profitable business like ACI Worldwide, the P/E ratio is a useful way to think about what you are paying for each dollar of earnings. It connects directly to the company’s bottom line, which is what ultimately supports shareholder returns over time.

What counts as a “normal” P/E depends on how the market views a company’s growth prospects and risk profile. Higher expected growth and lower perceived risk usually support a higher P/E, while slower growth or higher risk typically point to a lower one.

ACI Worldwide currently trades on a P/E of 17.19x, compared with the broader Software industry average of about 30.13x and a peer average of 60.10x. Simply Wall St’s Fair Ratio for ACI Worldwide is 25.07x. This is its proprietary estimate of a suitable P/E given factors such as earnings growth, profit margins, industry, market value and company specific risks. This Fair Ratio can be more useful than a simple comparison to peers or the industry, because it adjusts for the company’s own characteristics rather than assuming all software names deserve the same multiple. On this basis, ACI Worldwide’s current 17.19x P/E sits below the 25.07x Fair Ratio, which indicates that the shares may be undervalued on an earnings basis.

Upgrade Your Decision Making: Choose your ACI Worldwide Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let us introduce you to Narratives, a simple way to connect your view of ACI Worldwide’s business to the numbers you see on screen.

A Narrative is your story about the company, where you spell out what you expect for future revenue, earnings and margins, and link that to an assumed fair value instead of relying only on headline ratios like the P/E.

On Simply Wall St, Narratives live in the Community page and are designed to be easy to use. This means you can quickly compare your Fair Value to the current share price, see whether that points you toward buying, holding or selling, and then watch your view update automatically as new earnings, news or other data is added.

For ACI Worldwide, one investor might build a Narrative that assumes stronger transaction growth and assigns a higher fair value than another investor who focuses more on competition risk and arrives at a lower fair value. This shows how the same company can support quite different, but well structured, viewpoints.
