Early Career and Education
John Fieldly built his professional foundation around accounting, finance, retail, and consumer products. He began his career in retail through leadership positions with Eckerd Corporation, where his responsibilities included areas such as sales training, merchandising, impulse-sales strategy, and quality control.
His early retail experience gave him practical knowledge of how consumer products reach customers. He also supported Eckerd’s transition associated with its sale to CVS in 2004, an experience that added valuable exposure to a major corporate transaction.
Fieldly later developed his financial expertise through leadership roles at Lebhar-Friedman and Oragenics. At Oragenics, he served as Corporate Controller and was responsible for financial functions, reporting, planning, and operational efficiency.
He is a graduate of the University of South Florida, where he earned a Bachelor of Science degree in Accounting. He is also a Certified Public Accountant in Florida, giving him a strong professional foundation in financial management and corporate reporting.
Joining Celsius Holdings
Fieldly joined Celsius Holdings in January 2012 as Chief Financial Officer. His arrival came during an important period for the company, when Celsius was still developing its position in the competitive energy-drink market.
His financial background proved useful as the company worked on improving operations, managing resources, strengthening distribution, and developing its consumer-goods strategy. His experience across retail and finance allowed him to approach the business from both an operational and financial perspective.
Becoming CEO of Celsius
Fieldly’s responsibilities expanded significantly in March 2017 when he became Interim Chief Executive Officer while continuing as CFO. He became the company’s permanent CEO in April 2018 and has remained in that position.
He later became Chairman of the Board in August 2021. Fieldly also served as President until March 24, 2025. His current leadership positions are Chairman and Chief Executive Officer of Celsius Holdings.
Business Strategy and Leadership
One of Fieldly’s most important contributions has been helping Celsius develop a stronger identity within the energy-drink market. The company has focused heavily on consumers interested in fitness, active lifestyles, energy, and better-for-you beverage options.
Fieldly’s background in accounting has also influenced his approach to management. His career demonstrates a combination of financial discipline and consumer-business experience, with an emphasis on operational efficiency, distribution, procurement, and sustainable growth.
Celsius’ Major Growth
The scale of Celsius Holdings changed dramatically during Fieldly’s leadership. The company’s full-year 2025 revenue reached approximately $2.515 billion, compared with approximately $1.356 billion in 2024. That represented annual revenue growth of about 85.5%.
The company’s 2025 results were helped substantially by the addition of Alani Nu and Rockstar Energy to its portfolio. CELSIUS remained the company’s original flagship brand, while the broader portfolio allowed Celsius Holdings to compete across more consumer segments and consumption occasions.
PepsiCo Partnership
A major milestone in Celsius’ development was its relationship with PepsiCo. The partnership strengthened the company’s distribution capabilities and helped expand the availability of its products.
Under Fieldly’s leadership, Celsius has increasingly operated within a broader distribution and commercial ecosystem. The company’s 2025 results highlighted its role as PepsiCo’s energy category captain in the United States and reported an approximate 20% dollar share of the U.S. energy-drink category during the fourth quarter.
Business Companies and Ventures
John Fieldly’s publicly documented career is primarily connected with established companies rather than a collection of independent private ventures.
His major professional associations include Eckerd Corporation, Lebhar-Friedman, Oragenics, and Celsius Holdings. His career at Celsius has been by far his most prominent business leadership role.
Rather than building a widely documented personal business empire, Fieldly has focused his executive career on corporate leadership, financial management, consumer products, and the growth of Celsius Holdings.
Salary and Source of Income
As the CEO of a publicly traded company, Fieldly’s executive compensation is disclosed through Celsius Holdings’ public filings. His compensation can include salary, performance-based incentives, equity awards, and other executive benefits.
His principal documented professional income comes from his executive position at Celsius Holdings and related compensation. Personal net-worth estimates are not included here because a reliable, independently verified figure is not established by the company’s public filings.
Latest Career Developments
In 2026, Fieldly continues to serve as Chairman and CEO of Celsius Holdings. The company entered the year with a significantly expanded portfolio following its acquisition and integration of Alani Nu and Rockstar Energy.
Celsius reported first-quarter 2026 revenue of approximately $782.6 million, representing a 138% increase from the same quarter of 2025. Net income attributable to common shareholders also increased substantially compared with the prior-year period.
In February 2026, Celsius also announced the appointment of Christy Jacoby and John Short to its Board of Directors following nominations by PepsiCo. Fieldly said the appointments would strengthen the board’s expertise as Celsius continued scaling its portfolio and pursuing long-term growth.
Challenges and Positive Outlook
Fieldly’s leadership record is not without challenges. Managing three major energy brands creates operational complexity, and integrating acquisitions requires significant resources, distribution changes, and strategic coordination.
At the same time, Celsius’ recent financial results show considerable scale and growth. The company has expanded internationally, increased distribution, and built a broader energy portfolio. These developments provide Fieldly with an opportunity to strengthen the business while maintaining the momentum of its original CELSIUS brand.
