Read MoreHide Full Article

Key Takeaways

  • IBM shares slid 27% in six months, trailing an industry up 60.7% amid macro and AI shocks.
  • Anthropic says Claude Code can modernize COBOL, threatening IBM's mainframe consulting moat and pricing power.
  • IBM leans on hybrid cloud, HashiCorp, RedHat and watsonx as 2026-2027 earnings estimates rise.

International Business Machines Corporation (IBM - Free Report) has declined 27% over the past six months against the industry’s growth of 60.7% due to macroeconomic challenges and a sudden development in the artificial intelligence (AI) domain that threatens its core legacy businesses. The stock has lagged peers like Microsoft Corporation (MSFT - Free Report) and Amazon.com, Inc. (AMZN - Free Report) . While Microsoft has declined 18.2%, Amazon has rallied 10.7% over this period.

What Triggered IBM’s Fall From Grace?

IBM’s downslide was primarily triggered by an announcement from AI firm Anthropic that its Claude Code tool can modernize legacy COBOL systems — a foundational programming language deeply embedded in IBM’s mainframe ecosystem. With Claude Code proposing to substantially automate code exploration, documentation, refactoring and security analysis, it threatened to reduce enterprises’ reliance on specialized legacy service providers like IBM, bringing its sustenance at stake. 

IBM has long positioned itself as the dominant provider of mainframe systems optimized for high-volume, mission-critical workloads characterized by AI. Over decades, the company has built a durable revenue stream around maintaining, upgrading and modernizing legacy COBOL environments for large enterprises.

The complexity of COBOL systems has historically served as a competitive moat. Many organizations hesitate to rewrite or replace these systems due to cost, operational risk and the shrinking pool of developers familiar with the language. But it appears that the moat may now be facing AI-driven erosion.

COBOL remains deeply embedded in global infrastructure and continues to run in production daily across financial institutions, airlines, retailers and government systems. If Claude Code meaningfully reduces the cost and complexity of analyzing and migrating legacy systems, it could compress pricing power in IBM’s Consulting segment, introducing a new competitive dynamic into a space that has historically been a labor-intensive and high-margin business for the company.

Price Wars Compound IBM Woes

IBM is facing competition from Amazon Web Services and Microsoft Azure. Increasing pricing pressure is eroding margins, and profitability has trended down over the years, barring occasional spikes. Weaknesses in its traditional business and foreign exchange volatility remain significant concerns. High R&D cost is another concern.

IBM’s frequent acquisitions have also escalated integration risks. Buyouts have negatively impacted the company’s balance sheet, resulting in high levels of goodwill and net intangible assets. Moreover, a highly leveraged balance sheet has been troubling IBM over time.

Can Solid Hybrid Cloud, AI Demand Propel IBM?

Despite the setbacks, IBM is poised to benefit from healthy demand trends for hybrid cloud and AI, which drive the Software and Consulting segments. The company’s growth is expected to be aided by analytics, cloud computing and security in the long run. A combination of a better business mix, improving operating leverage through productivity gains and increased investment in growth opportunities will likely boost profitability.

With a surge in traditional cloud-native workloads and associated applications, along with a rise in generative AI deployment, there is a radical expansion in the number of cloud workloads that enterprises are currently managing. This has resulted in heterogeneous, dynamic and complex infrastructure strategies, which have led firms to undertake a cloud-agnostic and interoperable approach to highly secure multi-cloud management, translating into a healthy demand for IBM hybrid cloud solutions. 

The buyout of HashiCorp has significantly augmented IBM’s capabilities to assist enterprises in managing complex cloud environments. HashiCorp’s tool sets complement IBM RedHat’s portfolio, bringing additional functionalities for cloud infrastructure management and bolstering its hybrid multi-cloud approach. IBM’s watsonx platform is likely to be the core technology platform for its AI capabilities. watsonx delivers the value of foundational models to the enterprise, enabling them to be more productive.

Estimate Revision Trend

IBM is currently witnessing an uptrend in estimate revisions. Earnings estimates for IBM for 2026 have moved up 6.3% to $12.40 over the past year, while the same for 2027 has increased 5.1% to $13.36. The positive estimate revision portrays bullish sentiments about the stock’s growth potential.

End Note

IBM has invested heavily in its own AI capabilities, including watsonx, and could incorporate generative AI into its consulting workflows to improve efficiency rather than lose relevance. A strong emphasis on quantum computing and hybrid cloud is driving value for customers. With improving earnings estimates, the stock is witnessing a positive investor perception. 

However, IBM’s growth is dented by high operating costs and stiff competition that reduce its profitability. The company faces a potent threat from Anthropic and needs to fine-tune its business model to remain competitive. With a Zacks Rank #3 (Hold), IBM appears to be treading a middle-of-the-road path, and new investors may be better off trading with caution.
