Steelcase: Our Post-Close Leadership Structure

Letters from Steelcase President and CEO Sara Armbruster and HNI Chairmawn, President & CEO Jeff Lorenger

Steelcase Team,

As we move closer to combining with HNI, we want to share an important update about the leadership structure that will guide Steelcase following close.

This is an important moment in our company’s story. Times of change can bring mixed emotions, yet they also create opportunities for growth and shared success. What has always defined Steelcase is the strength of our people, the depth of our relationships, and our commitment to helping the world work better.

As part of this next chapter, I will be stepping aside and leaving Steelcase at close. As previously announced, HNI Chairman, President & CEO Jeff Lorenger will lead the combined company. Until close, I will continue to work closely with him and our teams to ensure a smooth and successful transition. My focus remains on supporting our people, our customers, and our shared priorities as we prepare for this new chapter.

I also want to share that two of our longtime executives will be making transitions of their own.

Bob Krestakos will leave Steelcase in early 2026 after supporting the operations transition. His focus in the coming months will be on ensuring continuity across our manufacturing and operations teams and supporting a smooth integration with HNI. After more than three decades with Steelcase in roles across the IT and Operations organizations, Bob has had a tremendous impact on our business and our people, and we will celebrate his career more formally as we get closer to his transition.

Donna Flynn will also leave Steelcase at close. During her 14 years with the company, Donna’s leadership of our Global Talent and Impact organization has shaped our culture in a multitude of ways — from how we lead, to how we develop our teams, to how we show up for one another. Prior to this role, she led WorkSpace Futures for nearly a decade, helping establish our insight-led approaches as a cornerstone of the Steelcase brand. Her passion for people, culture, and design has had a major impact on our company, and we will celebrate her many contributions in the weeks ahead.

Following close, Steelcase will move forward with an initial leadership structure, as outlined by Jeff below. The structure is intended to provide stability for our people, customers, and dealers while creating space for a thoughtful transition and a strong foundation for the future.

I want to thank our entire senior executive team for their leadership and partnership leading up to close and for their work to support the transaction and ensure a smooth transition. I also want to thank the executives who will continue supporting the organization as part of the initial leadership team. Their dedication and leadership have strengthened Steelcase, and we are deeply grateful for their commitment through this period of change.

It continues to be the privilege of my career to serve this incredible organization. I am deeply grateful for your trust, partnership, and care as we move through this important time together.

Sara Armbruster

President and CEO, Steelcase

 

 

Message from Jeff Lorenger

I want to begin by thanking Sara for her leadership and partnership throughout this process. Her dedication to Steelcase and her collaboration in preparing for a successful integration have been invaluable.

As we look ahead to the next phase of our combined journey, our approach to the post-close structure is anchored in three guiding principles:

 

1.

Protect revenue and performance.

The initial structure maintains Steelcase’s sales momentum by avoiding sudden changes in the roles closest to our dealers and customers and by ensuring near-term continuity in finance leadership to deepen our understanding of Steelcase’s revenue and profitability drivers.

 

2.

Phase integration thoughtfully.

This approach provides time for effective transitions so leaders can partner with key stakeholders and maintain stability while preparing for the future.

 

3.

Foster open communication and collaboration.

We are simplifying leadership structures over time to enhance agility, efficiency, and connection as we operate together as a larger, more diversified organization.

While reporting relationships may evolve, the foundation of Steelcase’s operating model remains unchanged. Enterprise Functions, Go-to-Market Platforms, and Go-to-Market Organizations will continue to play distinct roles in creating value and serving customers.

Initial leadership effective at close

 

•

Allan Smith — Go-to-Market and Product

Allan will continue leading Sales in Americas, Global Brand & Communications, Research, Product Development, Engineering and Design. He will report to me and focus on supporting integration while protecting core revenue through strong dealer and customer relationships. Madelyn Hankins will continue reporting to Allan and overseeing Americas Sales, Channel, and GCC; we have no plans to change the dealer or salesforce teams.

 

•

Terry Lenhardt will continue leading Marketing & Customer Verticals, reporting to Allan.

 

•

Dave Sylvester — Finance and International

Dave will continue as Steelcase’s senior finance leader, reporting to me, and will expand his responsibilities to include oversight of EMEA and APAC. He will partner with HNI teams to support the future direction of the business, including returning EMEA and APAC to profitability, delivering on integration synergies, and continuing to educate HNI leaders on Steelcase’s financial operations.

 

•

Alessandro Centrone (EMEA) and Peter Lewchanin (APAC) will report to Dave.

Dave will also continue partnering closely with Allan on strategic initiatives and priorities across the Americas.

Bob Krestakos — Operations

Bob will continue leading Operations and will report to Brandon Bullock, HNI Chief Operating Officer. He will remain with Steelcase following close to oversee operational continuity and integration planning, and he will leave Steelcase in early 2026 after supporting the transition. We will begin a search, considering internal and external candidates, to succeed Bob.

Bryan Saum will continue reporting to Steve with an expanded role, leading IT initiatives that support integration and serving as liaison to HNI’s IT organization.

 

•

Megan Blazina — Legal & Strategy

Megan will continue leading Legal and Strategy globally reporting to me, including Compliance, Trade, Regulatory, Government Affairs, Sustainability, Strategy, and Strategy Activation. To align ESG under one leader, Kim Dabbs will begin reporting to Megan at close. In addition, Megan will take on oversight for the Steelcase Global Business Centers.

 

•

Donna Flynn — Talent

As Sara shared, Donna will leave Steelcase at close. I’ve worked with Jen Petersen, HNI’s Head of Member and Community Relations, to align the teams that currently report to Donna. Meagan Baker, Jill Dark, Tracy Kurti, and Stephanie TenElshof will report to Jen and join her leadership team. Patrick Woo (APAC) and Nicole Benzler (EMEA) will report to Meagan, Isabel Medelin and the Talent Acquisition and Culture team will report to Jill, and the Compensation and Benefits team will now report to Kelly Livingston, HNI’s Vice President of Compensation and Benefits.

This initial leadership structure preserves momentum while we work together to define the long-term organization that will best position Steelcase for continued success within the HNI family. We are committed to maintaining clear communication throughout this transition and will continue sharing updates as plans develop. Our current estimate is that the acquisition will close sometime in December, subject to shareholder vote approval anticipated in early December.

I am grateful for your continued focus and commitment through this period of change. I have full confidence in the Steelcase team and our ability to continue delivering for our customers, supporting one another, and building a future full of opportunity.

Jeff Lorenger

Chairman, President & CEO, HNI Corporation
