Zillow Group has announced a significant transition in its financial leadership, appointing longtime finance executive Rikki Tremblay as its new Principal Accounting Officer, effective September 17, 2026. This strategic move comes as Chief Accounting Officer and Principal Accounting Officer Jennifer Rock retires from her full-time duties on the same date, though she will continue to serve the company in an advisory capacity until March 1, 2027. The announcement, detailed in a recent filing with the Securities and Exchange Commission (SEC), underscores Zillow’s commitment to maintaining continuity and stability in its financial operations during a period of evolving regulatory landscapes and market dynamics.
A Smooth Transition in Financial Leadership
The appointment of Tremblay signifies a deliberate and well-planned succession within Zillow’s accounting department. Rock, who has been instrumental in shaping the company’s financial reporting and controls, will step down from her executive roles after a distinguished tenure. Her decision to retire, as stated in the SEC filing, is a personal one, stemming from a desire to dedicate more time to her family. Crucially, Zillow has clarified that Rock’s departure is not a reflection of any disagreements regarding the company’s operations, policies, accounting practices, or financial disclosures, a detail that often carries significant weight for investors and stakeholders.
Rock herself expressed mixed emotions about her departure. "I gave this decision a lot of careful thought, and while I’ll miss Zillow, I’m excited to give my family my full attention," she stated. "I love this company and will be cheering them on long after I leave." This sentiment highlights the positive working relationships and commitment Zillow cultivates within its senior leadership.
Zillow’s Chief Operating Officer and Chief Financial Officer, Jeremy Hoffman, echoed Rock’s contributions and expressed the company’s gratitude. "We’re grateful to Jenn for everything she’s contributed to Zillow," Hoffman remarked. "We will miss her steady hand, her principled leadership, and her genuine care for the people around her, and we wish her all the best in her well-earned retirement." This endorsement from a key executive reinforces the respect and appreciation Rock commands within the organization.
Rikki Tremblay: A Deeply Rooted Zillow Finance Professional
The selection of Rikki Tremblay for the critical role of Principal Accounting Officer is a testament to her extensive experience and deep understanding of Zillow’s financial architecture. Tremblay has been an integral part of Zillow’s finance team since joining the company in December 2014. Over the past decade, she has steadily ascended through the ranks, holding a series of increasingly responsible positions in accounting and financial reporting.
Her most recent role, from February 2025 to September 2026, was Vice President of Reporting, Technical Accounting, and Controls. Prior to this, she served as Senior Director of Reporting, Technical Accounting, and Controls from February 2023 to February 2025, and Senior Director of Financial Reporting and Technical Accounting from February 2019 to February 2023. Her earlier years at Zillow, between 2014 and 2019, were also marked by contributions to various financial reporting and accounting leadership capacities. This comprehensive background ensures that Tremblay is well-equipped to navigate the complexities of Zillow’s financial landscape.
Before her tenure at Zillow, Tremblay honed her expertise in the audit sector. She spent five years at Deloitte & Touche LLP, from September 2009 to November 2014, where she progressed to the role of Audit Manager. This experience with one of the "Big Four" accounting firms provided her with a robust foundation in auditing principles, regulatory compliance, and best practices in financial reporting, which she has since applied and adapted within Zillow’s dynamic environment.
Continuity Amidst Evolving Scrutiny
The timing of this leadership change is particularly noteworthy. Publicly traded companies, including Zillow, are operating in an environment of heightened scrutiny regarding internal controls, revenue recognition practices, and the intricacies of stock-based compensation. The board of directors’ decision to appoint Tremblay to the Principal Accounting Officer role on September 16, 2026, the day before Rock’s official retirement, demonstrates a proactive approach to ensuring a seamless handover and maintaining the integrity of Zillow’s financial reporting.
This continuity is vital for investor confidence. Robust financial reporting and strong internal controls are fundamental to maintaining market trust and complying with the stringent requirements set forth by regulatory bodies like the SEC. Tremblay’s familiarity with Zillow’s systems, processes, and business model, coupled with her external audit experience, positions her to effectively address these ongoing challenges and uphold the company’s commitment to transparency and accuracy.
Background: Zillow’s Financial Evolution and Industry Context
Zillow Group, a leading online real estate marketplace, has undergone substantial transformation since its inception. From its beginnings as a platform for property listings, it has evolved into a comprehensive real estate ecosystem, offering a wide array of services including mortgage origination, title and escrow, and previously, an iBuying program (Zillow Offers, which was sunsetted). These expansions have naturally led to increased complexity in its financial reporting and a greater need for sophisticated accounting and control functions.
The real estate technology sector, or "proptech," has seen rapid growth and innovation. This dynamism, while fostering opportunities, also presents unique accounting challenges. For instance, the recognition of revenue from diverse service offerings, the valuation of intangible assets related to technology platforms, and the accounting for complex transactions all require meticulous attention to detail and adherence to evolving accounting standards.
Moreover, the regulatory environment surrounding public companies has become increasingly stringent, particularly following past corporate accounting scandals. The Sarbanes-Oxley Act of 2002 (SOX) significantly enhanced corporate governance and financial disclosure requirements, placing a greater onus on accounting officers to ensure compliance and the integrity of financial statements. Zillow, like all public companies, must continually invest in its internal control systems and maintain a highly competent accounting team to meet these demands.

Broader Implications for Zillow and the Market
The appointment of Rikki Tremblay as Principal Accounting Officer has several implications for Zillow Group and its stakeholders:
- Enhanced Stability and Predictability: Tremblay’s long-standing presence within Zillow’s finance department means she brings an intimate understanding of the company’s financial operations, historical performance, and strategic objectives. This internal promotion is likely to foster a sense of stability and predictability for investors and analysts who monitor Zillow’s financial health.
- Expertise in Technical Accounting and Controls: Her most recent roles highlight a specialization in technical accounting and internal controls. This is particularly relevant in the current regulatory climate, where robust control environments are paramount. Tremblay’s expertise in these areas will be crucial for navigating complex accounting issues and ensuring compliance with evolving standards.
- Maintaining Investor Confidence: In an industry often subject to market volatility and regulatory shifts, strong financial leadership is key to maintaining investor confidence. Tremblay’s appointment signals that Zillow is committed to upholding high standards of financial integrity and transparency.

Tremblay’s background suggests a capacity to support such growth while adhering to rigorous financial discipline.
- Advisory Role of Jennifer Rock: The continued involvement of Jennifer Rock as an advisor for several months is a significant asset. Her institutional knowledge and experience will be invaluable in guiding Tremblay through the initial stages of her new role and ensuring a comprehensive knowledge transfer. This phased transition minimizes the risk of information gaps and ensures that the company benefits from Rock’s expertise during this critical period.
The real estate technology sector is constantly evolving, and Zillow’s ability to navigate this landscape successfully hinges on strong operational and financial leadership. The transition from Jennifer Rock to Rikki Tremblay represents a carefully managed change that prioritizes continuity, expertise, and a commitment to the highest standards of financial stewardship. As Zillow moves forward, Tremblay’s role as Principal Accounting Officer will be pivotal in shaping its financial narrative and reinforcing its position in the market.
