PennyMac Financial Services, Inc. (NYSE: PFSI) has expanded its strategic agreement with Amazon Web Services, Inc. (NASDAQ: AMZN), designating AWS as its preferred cloud provider to deploy generative AI and modernize its mortgage servicing platform.

As part of the expanded agreement, PennyMac has developed a voice-based virtual assistant called the Natural Language Virtual Assistant (NLVA), built on Amazon Nova Sonic's speech-to-speech technology. The system is designed to handle after-hours calls, identify loan opportunities, deliver application links, and schedule callbacks, while human loan officers retain decision-making authority.

The agreement also covers accelerated cloud modernization of Plaisse, PennyMac's proprietary mortgage servicing platform, which the company has said it intends to commercialize for broader industry use.

"Pennymac has spent 18 years building the operational scale and institutional knowledge to lead this industry — and now we're translating that into technology that fundamentally changes how mortgages are made," said Jim Follette, Chief Digital Officer at PennyMac.

The broader initiative spans automated document processing, application upgrades, customer engagement tools, and data-driven decision-making capabilities, supported by dedicated AWS engineering resources.

PennyMac reported $154 billion in unpaid principal balance (UPB) of newly originated loans for the twelve months ended March 31, 2026, and serviced loans totaling $720 billion in UPB as of the same date.
