Fifth Third Bank is planning to implement new AI tools to assist with the acquisition of Dallas-based regional bank Comerica.
Fifth Third announced its acquisition of Comerica in October 2025.
“We actually have built some pretty cool tech tools for this conversion, effectively an intelligence layer that sits on top of the Microsoft Project Plan hard deck,” Fifth Third Chief Executive Tim Spence said during the bank’s second-quarter earnings call today.
The technology will monitor Microsoft Teams and Slack feeds for signs of conversion delays and then help create solutions.
Ahead of the conversion date, set for Labor Day weekend, the bank is conducting three mock conversions to test the process. Two have been completed and “that went very, very well,” Spence said.
In addition to using AI to assist in the conversion process, employees of the Cincinnati-based bank are using AI to boost productivity, Spence said.
The bank reported these AI metrics in Q2:
- AI tools responded to more than 1 million employee prompts in June;
- The percent of code written by AI and accepted by software developers was 45%; and
- More than 87% of unit testing — checking small, individual pieces of a bank’s software — was automated by AI.
Fifth Third also prioritized innovation in Q2 through finance platform updates and integration of an AI-powered search engine and a phishing and scam reporting tool into the mobile app.
“We do intend to accelerate the pace of investments that we make in AI,” Spence said.
In Q2, the $296 million bank reported:
- A net income of $801 million, up 28% year over year;
- Revenue of $3.3 billion, up 46% YoY;
- An average of 2.6 million customers per month using the mobile app; and
- Noninterest technology and communications expense of $250 million, up 98% YoY tied to Comerica integration activity.
Fifth Third [NYSE: FITB] shares were trading at $57.88 at 3:55 ET today, down 2.56% from market open. The bank has a market capitalization of $52.43 billion.

Executive Summary
Full Take
The narrative focuses on the application of AI not just for operational efficiency but as a critical mechanism within a complex, high-stakes corporate transaction—the acquisition and integration of Comerica. The repeated emphasis on AI tools used for monitoring delays suggests a tension between the speed of technological implementation and the inherent complexity and risk of large-scale financial mergers. The presentation of AI productivity metrics (e.g., 45% code generation) alongside massive financial growth ($3.3B revenue, $801M net income) creates an implicit linkage: the successful navigation of this acquisition is framed as being dependent on, or accelerated by, this technological adoption. The pattern suggests that in high-velocity corporate change, innovation becomes a necessary operational prerequisite rather than a separate strategic goal. This framing shifts the focus from *why* the merger is happening to *how* it is being executed technologically. The cost implications for integration—evidenced by the 98% YoY spike in technology spending tied directly to Comerica activity—appear deeply intertwined with the AI strategy.
BRIDGE QUESTIONS: What are the specific risk models used to validate the predictive power of the AI layer during conversion monitoring? How do the productivity gains realized internally translate into measurable, defensible financial synergies post-acquisition? What oversight mechanisms are in place to ensure the rapid deployment of these sophisticated tools does not introduce unforeseen compliance or integration errors?
