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

A Discounted Cash Flow, or DCF, model estimates what a company might be worth by projecting its future cash flows and discounting them back to today’s value. It is essentially asking what tomorrow’s cash is worth in your pocket right now.

For ACI Worldwide, the model uses 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. Analyst inputs and extrapolated estimates extend out ten years, with projected Free Cash Flow of $513.2 million in 2035. These figures are all in $ and represent cash potentially available to equity holders after necessary spending.

Combining these projected cash flows, the DCF model arrives at an estimated intrinsic value of $65.12 per share, compared with a recent share price of about $41.83. On this basis, the stock screens as roughly 35.8% undervalued relative to the model’s estimate.

Approach 2: ACI Worldwide Price vs Earnings

For profitable companies, the P/E ratio is a useful way to think about what you are paying for each dollar of current earnings. A higher P/E usually reflects higher growth expectations or a perception of lower risk, while a lower P/E can signal more modest expectations or higher perceived risk.

ACI Worldwide currently trades on a P/E of 16.53x. This sits below the Software industry average P/E of 27.99x and the peer group average of 40.60x, so the market is assigning a lower earnings multiple to ACI Worldwide than to many of its listed software peers.

Simply Wall St’s Fair Ratio for ACI Worldwide is 23.06x. This is a proprietary estimate of what an appropriate P/E could be, based on factors such as the company’s earnings growth profile, industry, profit margins, market cap and specific risks. Because it blends these company specific inputs, the Fair Ratio can give a more tailored reference point than a simple comparison with peers or a broad industry average.

Comparing the Fair Ratio of 23.06x with the current P/E of 16.53x suggests the shares are trading below that model based reference point.

Earlier we mentioned that there is an even better way to understand valuation. On Simply Wall St’s Community page you can use Narratives to attach your own story to ACI Worldwide’s numbers. You can link your view of its future revenue, earnings and margins to a forecast and a Fair Value that you can compare with the current price to help inform your decision.

For example, one Narrative might lean toward the higher Fair Value of US$77.00 based on confidence in areas like cloud native payments and real time fraud solutions. Another might sit closer to the lower Fair Value of US$48.73 because it puts more weight on risks around legacy systems, competition and customer concentration.
