Executive Overview
In a major leadership transition within the environmental services sector, WM (formerly Waste Management, Inc.) has announced that Chief Executive Officer Jim Fish is stepping down after a remarkably successful ten-year tenure at the helm. Effective January 4, current President John Morris will assume the role of CEO, bringing more than three decades of industry experience to the company’s highest office.
Fish, whose career with WM spans approximately 25 years, has been the architect of a transformative decade for the company. Under his visionary leadership, WM nearly doubled its annual revenue, executed multi-billion-dollar strategic acquisitions, and spearheaded massive infrastructural investments in recycling and renewable natural gas (RNG). As Fish prepares to transition out of the company—serving in an advisory capacity through mid-February—industry watchers are turning their attention to Morris, a veteran executive who began his career in the waste sector as a college student driving collection trucks.
This executive shuffle marks the second major CEO transition among publicly traded waste management giants within a relatively short window, following Ned Coletta’s elevation to CEO of Casella Waste Systems in January after the retirement of longtime leader John Casella. For WM, Morris’s ascension represents both continuity and forward-looking ambition, signaling a sustained commitment to technological modernization, operational efficiency, and sustainable long-term growth.
Detailed Chronology and Legacy of Jim Fish’s Decade as CEO
When Jim Fish assumed the role of CEO in 2016, the waste and recycling industry stood at a complex crossroads, facing mounting regulatory pressures, shifting global commodity markets, and an urgent need for infrastructure modernization. Over the subsequent decade, Fish navigated these challenges by steering WM away from traditional, volume-dependent paradigms and toward high-value, sustainable operations.
The Foundation of Growth and Multi-Billion Dollar Acquisitions
Fish’s tenure will long be defined by his aggressive and strategically astute merger and acquisition (M&A) strategy. Two major milestones fundamentally expanded WM’s market footprint and service capabilities during his decade-long run:
- The Advanced Disposal Acquisition (2020): Valued at approximately $4.6 billion, this deal solidified WM’s presence in key eastern and midwestern U.S. markets, eliminating a major competitor and generating substantial operational synergies.
- The Stericycle Acquisition (2024): In a massive $7.2 billion transaction, WM expanded its portfolio into specialized medical waste management services, diversifying its revenue streams and capturing a vital, highly regulated market segment.
Concurrently, WM poured capital into cutting-edge recycling facilities and renewable natural gas infrastructure. By turning landfill gas into clean energy and upgrading material recovery facilities (MRFs) with advanced sorting technologies, Fish positioned WM not merely as a waste hauler, but as an indispensable environmental solutions provider.
Financial Transformation
The tangible results of Fish’s strategic roadmap are vividly reflected in WM’s financial balance sheets. When Fish took the reins in 2016, WM reported an annual revenue of $13.6 billion. By the close of fiscal year 2025, that figure had nearly doubled, reaching $25.2 billion.
Reflecting on his tenure, Fish expressed profound gratitude in a public statement:
"I’m grateful for the opportunity to have served as WM’s CEO over the past decade and proud of all our team has accomplished together."
To ensure a seamless handover, Fish will officially step down from the board of directors upon Morris’s appointment on January 4, but will remain on board in an advisory capacity until mid-February to guide the executive team through the transition.
Supporting Context and Metrics: The Rise of John Morris
John Morris steps into the CEO role with a rare synthesis of grassroots industry experience and high-level corporate governance. Unlike executives who enter the waste sector solely through finance or corporate law, Morris’s journey began in the cab of a collection truck during his college years.
A Grassroots Upbringing to the C-Suite
Over a 30-year career spanning various operational and strategic domains, Morris has systematically climbed the ranks within WM. His extensive resume includes:
- Market Area General Manager of New York City
- Area Vice President of the Greater Mid-Atlantic Area
- Senior Vice President of Field Operations
- Chief Operating Officer
- Chief Strategy Officer
- President (named in 2025)
This comprehensive trajectory has provided Morris with an intimate, ground-level understanding of the mechanics of waste collection, fleet logistics, and customer service. Kathleen Mazzarella, chair of WM’s board of directors, highlighted this unique background:
"Over three decades of industry experience have given him a deep understanding of our business, culture, and opportunities. He’s overseen innovative service delivery to enhance customer experience while reducing operating expenses. All of this was accomplished while improving employee satisfaction, safety, and retention."
Technology, Fleet Upgrades, and Operational Modernization
Even before his appointment as CEO, Morris played a pivotal role in shaping WM’s modern operational footprint. In his capacity as president, he managed executives overseeing sustainability, enterprise strategy, and customer experience. Crucially, he spearheaded field operations that integrated cutting-edge technologies into the company’s vast fleet.
Under Morris’s operational oversight, WM has rolled out advanced route optimization software, artificial intelligence (AI) upgrades for safety and sorting, and pilot programs for autonomous collection vehicles. These innovations have directly targeted dual corporate goals: maximizing fleet efficiency and dramatically improving safety metrics for frontline workers.
The leadership pipeline leading to Morris’s appointment also reflects a broader C-suite evolution at WM. Earlier in the year, the company promoted Tara Hemmer from Chief Sustainability Officer to Chief Operating Officer in May, cementing a dynamic leadership team designed to execute complex, tech-forward strategies.
Official Statements and Industry Perspective
The corporate announcement elicited widespread praise from outgoing leadership, the board of directors, and incoming executives alike, painting a clear picture of a company united behind its cultural and operational values.
Jim Fish was quick to endorse his successor, describing Morris as a resilient, forward-thinking leader:
"John is a strong leader and a champion for our people, safety, innovation, and operational excellence."
Upon accepting his new responsibilities, Morris underscored his dedication to preserving WM’s foundational ethos while driving aggressive modernization:
"For decades, WM has been built on a strong foundation of safety, service, and operational excellence. I am committed to building on that legacy while strengthening our position for innovation and continued long-term growth."
Mazzarella also took the opportunity to honor Fish’s profound cultural impact on the organization, noting that his leadership extended far beyond financial returns:
"Jim’s philosophy on stakeholder priorities is simple: Jim always puts people first, knowing that they, in turn, will take care of the customer and the business. As a result, Jim’s legacy includes making WM a great place to work."
The transition occurs against the backdrop of shifting leadership across the broader waste management landscape. With Casella Waste Systems also undergoing a foundational CEO transition with Ned Coletta replacing John Casella earlier this year, the North American environmental services sector is experiencing a generational shift in leadership. Industry veterans are handing over the reins to executives schooled in digital transformation, environmental sustainability, and complex corporate integration.
Future Outlook: What’s Next for WM Under John Morris?
As John Morris assumes the CEO title on January 4, the strategic imperatives facing WM are clear. The company must continue to integrate its massive $7.2 billion Stericycle acquisition, scaling its regulated medical waste operations while maintaining the efficiency of its core solid waste and recycling divisions.
Furthermore, investors and analysts will be closely monitoring how Morris accelerates WM’s technological transformation. The ongoing integration of AI-driven route optimization, smart-fleet mechanics, and autonomous vehicle pilots will be critical in mitigating labor shortages, reducing carbon emissions, and controlling operating expenses in an inflationary macroeconomic climate.
At the same time, regulatory and consumer demand for circular economy solutions will keep sustainability at the forefront of WM’s agenda. With upgraded MRFs and expanded renewable natural gas (RNG) production facilities coming online, Morris inherits a robust infrastructure capable of capitalizing on corporate and municipal ESG (Environmental, Social, and Governance) targets.
Key Milestones to Watch in 2026:
- The Official Handover (January 4): John Morris takes over as CEO and joins the board of directors, while Jim Fish steps down from the board and transitions into his advisory role.
- Advisory Period Conclusion (Mid-February): Jim Fish officially concludes his formal advisory tenure, leaving Morris and COO Tara Hemmer with full operational and strategic control.
- Post-Stericycle Synergy Realization: Financial reports throughout 2026 will test WM’s ability to extract projected value from the medical waste acquisition.
- Technology Deployment Rollouts: Further scaling of AI enhancements, safety tech, and fleet electrification initiatives across WM’s nationwide network.
Ultimately, while Jim Fish leaves behind monumental financial achievements and a deeply engrained "people-first" culture, John Morris enters the corner office uniquely equipped to guide WM into its next chapter of technological sophistication and sustainable market dominance.
