🧾 What This Document Is

This is an 8-K filing, which is a report companies file with the SEC to announce major, timely news that shareholders should know about. This specific filing announces a leadership transition at the top of two key departments.

👉 Why it matters: When a company loses or changes an executive, especially one who built core technology, investors want to know if the transition is smooth and if the company's future strategy remains solid.

🏢 What The Company Does

In simple terms, Lineage is like the world's biggest landlord for giant refrigerators. It's a Real Estate Investment Trust (REIT) that owns and operates over 500 temperature-controlled warehouses globally. These are critical for the food supply chain, helping move everything from frozen veggies to ice cream without spoilage.

👉 Why it matters: This context shows why technology leadership is so vital for them. Their warehouses aren't just cold; they're smart, powered by proprietary software that needs steady, expert leadership.

👥 The Key Leader & His Legacy

The announcement centers on Sudarsan Thattai, who held the dual roles of Chief Information Officer (CIO) and Chief Transformation Officer (CTO). He's been with Lineage for 13 years, joining in 2013.

• His Big Contribution: He built the foundation for Lineage's tech and innovation. He's specifically credited with leading the development of LinOS, the company's proprietary warehouse software that helps run operations efficiently.
• His Background: Before Lineage, he was a senior tech leader at a logistics company called UTi Worldwide.

👉 Why it matters: He wasn't just maintaining systems; he created a key competitive advantage (LinOS). His departure after such a long tenure is a significant change.

🔄 The Transition Plan

The company isn't just losing Thattai; they have a phased, multi-year plan to handle his departure.

• Immediate Change: Day-to-day leadership of the global IT and technology team will shift to Chris Johnson (CJ), who is the Vice President of Technology Projects.
• Thattai's New Focus: He will step back from daily management to concentrate on high-impact, future-oriented IT priorities.
• Final Departure: Thattai will fully retire in April 2027. Until then, he remains in the CTO role to support CJ and ensure a smooth handoff.

👉 Why it matters: This isn't a sudden ouster. It's a planned, year-long runway meant to transfer knowledge and keep major projects on track. It shows thoughtful governance.

🌟 What The Company Says

The CEO, Greg Lehmkuhl, publicly thanked Thattai for his leadership and contributions. The tone is one of gratitude and confidence. Thattai himself expressed pride in what his team built and confidence that Lineage is "well positioned for sustained growth and innovation."

🧠 The Analogy

Think of this like a master chef who founded a famous restaurant. They're not closing the kitchen. Instead, they're stepping back from the daily rush to plan new recipes, while their trusted sous-chef takes over the stovetop. The founder stays on as a consultant for the next year to make sure the new dishes taste just right.

🧩 Final Takeaway

Lineage is managing a planned, orderly succession for a long-tenured technology executive. The multi-year transition plan for Sudarsan Thattai aims to preserve the momentum of mission-critical tech initiatives and ensure his deep expertise is passed on, minimizing disruption to the company's operations and innovation pipeline.
