A Rocky Mountain bank deliberately shrinking after a decade of acquisitions, whose CEO is consolidating data into 'one clean source' to support AI and is piloting a Fiserv-built agentic AI tool for commercial loan onboarding.
How is First Interstate using AI?
First Interstate BancSystem, the Billings, Montana parent of First Interstate Bank with about $26 billion of assets (a footprint it is consolidating from 14 states to 10 contiguous ones), is the rare regional bank that is both shrinking on purpose and piloting agentic AI. President and CEO Jim Reuter, the former FirstBank of Colorado chief who arrived in late 2024, has sold a dozen branches in Arizona and Kansas, exited indirect auto lending, outsourced the consumer credit card, sold 11 rural Nebraska branches, run off transactional loans and, in the first quarter of 2026, completed a redesign of the banking organisation into 'a flatter, more streamlined model', all in the name of relationship banking and 'disciplined organic growth' after activist HoldCo Asset Management attacked the bank's acquisition record. The technology thread runs alongside: Reuter told investors the bank has been working toward 'one clean data source' to support initiatives including AI, due to wrap up in early summer 2026, and that improvements to online account opening and Zelle have produced 'positive results'. In May 2026 Fiserv named First Interstate one of six banks it co-developed AI agents with on its new agentOS platform, built with OpenAI; the bank is piloting an agent for commercial loan onboarding that Reuter says has cut manual data entry and cycle times, delivered through the core so agentic tools 'simply integrate' into daily workflows. First-quarter 2026 net income was $60.2 million, or $0.61 per share, with a 14.30% CET1 ratio and about $84 million of buybacks. Fiserv's own launch release names First Interstate as one of two institutions already running agentOS pilots, with 'measurable results' in commercial loan onboarding, and quotes Reuter on 'automating loan onboarding directly to our Fiserv core'. On the same first-quarter call Reuter said the bank is also piloting AI-related tools including a business-development tool that helps bankers prepare for client calls, and in May 2026 it put Prolific Banking's On-Ramp automated treasury-management enrollment into production. The 2025 10-K carries a stand-alone AI risk factor: 'ultimately, we may offer products or services incorporating AI', making the necessary AI investments may take 'significant financial, human, and other resources', and rivals with greater resources may out-invest it. Second-quarter 2026 net income was $83.9 million, or $0.87 per share, including a $19.5 million gain on the Nebraska branch sale, with CET1 at 14.54%. The leadership bench has turned over: chief operations officer Kristina Robbins was moved to an advisory role in May 2026, and on 14 September Jeff Lee, a former chief digital officer and chief operations and technology officer at Seacoast Banking Corporation of Florida, took over as chief operations officer; in July the board added Kevin Turner, a former Microsoft chief operating officer and Walmart CIO. The bank also warns customers that AI search summaries often misstate interest rates. First Interstate Bank is a Montana state member bank supervised by the Federal Reserve; no AI budget has been disclosed and the agent remains a pilot.

- Piloting a Fiserv agentOS AI agent for commercial loan onboarding, co-created with Fiserv and OpenAI; CEO reports reduced manual data entry and cycle times.
- 'One clean data source' project to support AI and other technology initiatives, targeted for completion in early summer 2026.
- Deliberate shrinkage: branch sales in Arizona, Kansas and Nebraska, exit from indirect auto and credit cards, loan run-off, flatter organisation completed Q1 2026.
- Activist HoldCo Asset Management pressed the board to swear off acquisitions; management says the focus is disciplined organic growth.
- Q1 2026 net income $60.2 million ($0.61 per share); CET1 14.30%; about $84 million of buybacks.
- Customer education on AI search summaries misstating interest rates (November 2025).
- Other AI pilots: a business-development tool that helps bankers prepare for client calls (Q1 2026 call); automated treasury-management enrollment (Prolific On-Ramp) in production since May 2026.
- 2025 10-K: stand-alone AI risk factor (the bank may offer AI products; investment needs may be significant; rivals may out-invest it; AI regulation and IP law are shifting).
- New chief operations officer Jeff Lee (from 14 September 2026; ex-Seacoast chief digital officer and COO/technology officer) replaces Kristina Robbins; former Microsoft COO Kevin Turner joined the board in July 2026.
- Q2 2026 net income $83.9 million ($0.87 per share); CET1 14.54%; total assets $25.9 billion at 30 June 2026.
- No head of AI, chief AI officer or chief data officer is named in the 2025 10-K, the 2026 proxy or the 2026 8-K filings. Technology sits with chief information officer Lori Meyer, security with chief information security officer Dale Daugherty (in the role since 2021); its chief risk officer, Nathan Jones, left for WesBanco in April 2026.
- Reuter on the 30 April 2026 call: 'stare and compare' jobs in audit, compliance and other areas are 'ripe for AI to make you more efficient', and without a good data source 'you'll just make bad decisions faster'. The data project was due to finish in early summer 2026.
- The stand-alone AI risk factor first appeared in the 10-K for 2024, filed 28 February 2025; the 10-K for 2023 mentioned AI only inside technology and regulation risk factors. The 2025 10-K repeats it, and the Q2 2026 10-Q reports no material change to risk factors and does not mention AI.
- The Q2 2026 call (24 July) named neither AI nor agents: Reuter cited 'further investment in data management to support our ability to leverage new technology' and staffing aligned to the new operating model. Quarterly salaries and wages fell to $64.9 million from $68.5 million.
- Board oversight: the Technology, Innovation and Operations Committee, chaired by director Joyce Phillips, met four times in 2025 and reviews technology and innovation investment proposals. The proxy's risk-oversight map also lists model risk and third-party risk.
- The bank's AI supply chain is indirect: Fiserv's agentOS was built with OpenAI and runs on Amazon Bedrock AgentCore, according to AWS and American Banker. No patents assigned to First Interstate were found.
What is Fiserv agentOS pilot and the 'one clean data source' project?
First Interstate co-created an AI agent for commercial loan onboarding with its core provider Fiserv on the agentOS platform, which Fiserv built with OpenAI on AWS Bedrock and launched in May 2026 with 'bank-grade controls' for policy, governance, auditability and recordkeeping. The agent addresses a process that 'straddles multiple systems' and is 'super manual', and CEO Jim Reuter says it has already reduced manual data entry and cycle times: 'Delivery of an agentic operating system through our core allows us to simply integrate agentic tools into our daily workflows.' Underneath it, the bank has been consolidating its data into 'one clean data source' to support technology initiatives including AI, a project expected to finish in early summer 2026, alongside improvements to online account opening and Zelle.[5][4]
What AI partnerships and patents does First Interstate have?
First Interstate's one public AI partnership runs through its core provider Fiserv: it co-created a commercial loan onboarding agent on Fiserv's agentOS and has piloted it since May 2026. AWS and American Banker say agentOS was developed with OpenAI and runs on Amazon Bedrock AgentCore, so OpenAI and AWS reach the bank only through Fiserv; no direct contract is disclosed. A Google Patents search for First Interstate Bank and First Interstate BancSystem found no granted patents or published applications assigned to the bank. No AI budget, model provider or data-platform vendor is public.[5][6][25]

What does the public record suggest about First Interstate's AI strategy?
Analysis by BankingNewsAI from the sources cited on this page. Observations, not advice.
01
Core-delivered agents are the community-bank path
First Interstate shows how a mid-size bank gets agentic AI without a lab: through its core provider, with the vendor's controls as the governance baseline.
02
Data first, then agents
Consolidating to one clean data source before scaling the pilot is the right order and the part examiners will ask about.
03
Shrinking creates budget
Branch sales and business exits free expense for technology; the bank should say how much is redirected.
04
Concentration risk sits with Fiserv
Core, agent platform and model provider in one chain is convenient and a single point of failure; SR 23-4 due diligence should cover OpenAI and AWS beneath Fiserv.

Its peer group on this site, by business model and size:
Does First Interstate Bank use AI?
Yes, in pilot. First Interstate co-created an AI agent for commercial loan onboarding with Fiserv on its agentOS platform, built with OpenAI, and is piloting it; CEO Jim Reuter says it has reduced manual data entry and cycle times. The bank is also consolidating its data into one clean source to support AI, piloting an AI tool that helps bankers prepare for client calls, and has automated treasury-management enrollment with Prolific Banking. Its 10-K treats AI as a stand-alone risk factor.
Who runs operations and technology at First Interstate?
Jeff Lee became executive vice president and chief operations officer on 14 September 2026, bringing experience in operations, technology, digital banking, information security, marketing and business transformation, most recently as chief digital officer and then chief operations and technology officer at Seacoast Banking Corporation of Florida. He succeeded Kristina Robbins, who left the COO role in May 2026. CEO Jim Reuter fronts the Fiserv agentOS pilot.
Why is First Interstate getting smaller?
Under CEO Jim Reuter the bank is refocusing on relationship banking and disciplined organic growth after years of acquisitions: it sold branches in Arizona, Kansas and Nebraska, exited indirect auto lending, outsourced its credit card and let transactional loans run off, while activist HoldCo Asset Management pressed it to stop acquiring.
Who leads AI at First Interstate?
No head of AI, chief AI officer or chief data officer is named in First Interstate's 10-K, 2026 proxy or 8-K filings. CEO Jim Reuter fronts the effort and announced the Fiserv agentOS pilot in May 2026. Technology sits with chief information officer Lori Meyer, who became interim CIO in June 2023; chief information security officer Dale Daugherty has held the security role since 2021. Jeff Lee, formerly Seacoast's chief digital officer, became chief operations officer on 14 September 2026. Board oversight sits with the Technology, Innovation and Operations Committee, chaired by director Joyce Phillips.
What does First Interstate say about AI in its SEC filings?
The 10-K for 2024, filed on 28 February 2025, added a stand-alone AI risk factor, repeated in the 2025 10-K filed on 26 February 2026. It says the bank may offer AI products, that AI investment may need significant financial and human resources, that larger rivals may out-invest it, and that biased or inaccurate AI could bring legal and reputational harm. The cyber section warns attackers may use AI and machine learning. The Q2 2026 10-Q reports no material change to risk factors and does not mention AI.
Which AI technology partners does First Interstate use?
Publicly, one: its core provider Fiserv. First Interstate co-created a commercial loan onboarding agent on Fiserv's agentOS, launched on 14 May 2026, and pilots it. According to AWS and American Banker, agentOS was developed with OpenAI and runs on Amazon Bedrock AgentCore, but the bank has not named either as a direct vendor. Prolific Banking's On-Ramp automates treasury enrollment and is not described as AI. A Google Patents search for the bank's names found no patents assigned to it.
