• If you are wondering whether International Business Machines stock is pricing in too much optimism or leaving value on the table, the starting point is understanding how its current share price compares with underlying fundamentals.
• The stock recently closed at US$231.31, with returns of 0.1% over 7 days, a 5.6% decline over 30 days, a 20.6% decline year to date, and gains of 6.0% over 1 year, 110.8% over 3 years and 104.3% over 5 years. These figures set the backdrop for any valuation check.
• Recent headlines around International Business Machines have focused on its position in enterprise technology and its role in areas such as cloud, software and services. These factors can shape how investors think about its long term earnings potential and risk profile, and are often front of mind when markets reassess what they are willing to pay for the stock.
• On Simply Wall St's valuation model, International Business Machines scores a 5 out of 6 for being undervalued across different checks. This sets up a closer look at the usual valuation tools like P/E multiples and cash flow models, followed by a final section that walks through a more complete way to think about value beyond just a single metric.

Approach 1: International Business Machines Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model takes forecasts of a company’s future cash flows and discounts them back to today’s dollars to estimate what the whole business might be worth right now.

For International Business Machines, the model uses a 2 Stage Free Cash Flow to Equity approach, starting from last twelve months free cash flow of about $12.2b. Analysts provide explicit free cash flow estimates out to 2030, such as $15.7b in 2026 and $18.4b in 2028, with Simply Wall St extending the projections further using its own assumptions for later years.

Bringing these projected cash flows back to today using a discount rate yields an estimated intrinsic value of around $339.76 per share. Compared with the recent share price of $231.31, the model suggests an intrinsic discount of about 31.9%, which points to the stock being undervalued on these cash flow assumptions.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests International Business Machines is undervalued by 31.9%. Track this in your watchlist or portfolio, or discover 51 more high quality undervalued stocks.

Approach 2: International Business Machines Price vs Earnings

P/E is a common way to look at profitable companies because it ties what you pay directly to the earnings the business is generating today. As a rule of thumb, higher expected earnings growth and lower perceived risk can justify a higher P/E, while slower growth and higher risk tend to line up with a lower P/E being seen as normal.

International Business Machines currently trades on a P/E of 20.26x. That sits close to the broader IT industry average of 20.57x, but above the peer group average of 13.01x, so on simple comparisons the stock looks more expensive than many peers but roughly in line with the sector overall.

Simply Wall St’s Fair Ratio for International Business Machines is 30.47x. This is a proprietary estimate of what the P/E might be given factors such as the company’s earnings profile, industry, profit margins, market cap and identified risks. Because it folds these elements into a single figure, it can be more tailored than a basic peer or industry average comparison. Setting the current P/E of 20.26x against the Fair Ratio of 30.47x suggests the stock is trading below what this framework would imply.

Result: UNDERVALUED

Implied overvaluation vs the recent US$231.31 share price: roughly 14.8%.

Revenue growth assumption: 3.72% a year.
