Niagen Bioscience, Inc. Reports First Quarter 2025 Financial Results and Increases Outlook
Total net sales of $30.5 million, up $8.3 million or 38% year-over-year, gross margin of 63.4%, net income of $5.1 million and Adjusted EBITDA of $4.9 million for the three months ended March 31, 2025 and increased full year 2025 outlook.
LOS ANGELES, CA - May 7, 2025 - Niagen Bioscience, Inc. (NASDAQ:NAGE) today announced financial results for the first quarter of 2025.
First Quarter 2025 Financial and Recent Operational Highlights
•Total net sales were $30.5 million, with $21.5 million from Tru Niagen®, up 38%, and 24%, respectively, from the prior year quarter.
•Total Niagen® ingredient sales, including food-grade and pharmaceutical-grade, reached $8.0 million, up 95% YoY.
•Delivered strong gross margin of 63.4%, up 270 basis points from the prior year quarter.
•Sales and marketing expense as a percentage of net sales was 26.6%, an improvement of 380 basis points, compared to 30.4% from the prior year quarter.
•Delivered net income of $5.1 million or $0.07 earnings per share, an improvement of $5.6 million and $0.08 per share from the prior year quarter.
•Adjusted EBITDA, a non-GAAP measure, was $4.9 million, a $4.2 million improvement from the prior year quarter.
•Total cash provided by operations of $7.9 million, ending the quarter with $55.6 million in cash.
•Increased full year 2025 outlook: Net sales growth expected between 20%–25% (previously approximately 18%), reflecting continued strength in the expanding NAD+ market. Adjusted general and administrative expenses now expected to increase $7.0–$8.0 million (previously $5.0–$6.0 million), primarily due to revised share-based compensation estimates. Full year 2025 outlook continues to project profitability.
•The Company announced its corporate name change to Niagen Bioscience, Inc. and commenced trading under the new Nasdaq ticker “NAGE,” effective March 19, 2025. This rebrand reflects the Company’s legacy and leadership in healthy aging through its flagship ingredient, Niagen®, reinforcing its renewed mission: “There’s a better way to age.”
•On March 20, 2025, the Company expanded its NAD+ precursor intellectual property portfolio with a newly granted patent which covers the composition of matter for nicotinamide riboside (NR) salt forms, including NR Malate and NR Tartrate, and other NR derivatives. This is part of a family of patents also covering methods of making NR and related derivatives, some of the most efficient NAD+ precursors, which Niagen Bioscience has obtained through an exclusive license from Queen’s University Belfast.
“We are proud to start the year with another record quarter, delivering $30.5 million in net sales, a 38% year-over-year growth fueled by both Tru Niagen® and strong Niagen® ingredient demand, a 63.4% gross margin, and $5.1 million in net income,” said Niagen Bioscience CEO Rob Fried. “With strong momentum heading into 2025, and with the launch of our new brand identity and expansion of our NAD+ precursor patent portfolio, we are reinforcing a powerful foundation for the future of healthy aging and are energized by the market’s growing trust in Niagen.”

Results of operations for the three months ended March 31, 2025 compared to the prior year quarter
Net Sales for Niagen Bioscience increased 38%, or $8.3 million, to $30.5 million. The growth in net sales was driven by combined growth in Tru Niagen sales and Niagen® ingredient sales, including a significant increase in food-grade Niagen® sales and the ramp-up of pharmaceutical-grade Niagen® sales, which were not sold in the prior year quarter.
Gross Margin improved 270 basis points to 63.4% primarily due to changes in product mix and business mix as well as improvements in labor and overhead utilization rates with higher sales.
Operating Expense increased 3%, or $0.4 million, to $14.6 million.
•Selling and marketing expense increased $1.4 million, and improved 380 basis points as a percentage of net sales to 26.6% of net sales, reflecting greater efficiencies from the increased investments which were primarily in advertising and marketing to support brand growth in our consumer products segment.
•General and administrative expense decreased 3%, or $0.2 million, driven by a $1.3 million recovery of credit losses related to a legal settlement, largely offset by increases in professional, consulting service and employee related expenses.
•Research and development expenses decreased $0.8 million, normalizing to historical levels compared to the prior year quarter, when spending was elevated to support the successful launch of the Niagen Plus product line, including work on pharmaceutical-grade Niagen®.
Net Income was $5.1 million, or $0.07 per share, compared to a net loss of $0.5 million or $(0.01) per share for the first quarter of 2024.
Adjusted EBITDA, a non-GAAP measure, was $4.9 million, up from $0.7 million for the first quarter of 2024. See “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of non-GAAP Adjusted EBITDA to net loss, the most directly comparable GAAP measure.
Cash Flows from Operating Activities had a net cash inflow of $7.9 million for the three months ended March 31, 2025 compared to $0.3 million in the prior year. The approximately $7.6 million increase in cash provided by operating activities was primarily driven by improvements in net income (loss), relatively higher collections on trade receivables, and a relative increase in accounts payable. These increases were partially offset by a decrease in credit loss expense due to a recovery of previously written-off amounts and higher inventory purchases associated with scaling our inventory reserves.
2025 Full Year Outlook
Looking forward, for the full year, the Company expects between 20% to 25% year-over-year revenue growth. This outlook reflects anticipated continued expansion of the Company’s e-commerce business, growth through established partnerships, and increased revenue from the pharmaceutical-grade Niagen® ingredient business. Gross margin is expected to improve slightly year-over-year, driven by ongoing supply chain optimization efforts, cost savings initiatives, and overall business scale. Selling and marketing expenses are projected to increase in absolute dollars but decrease as a percentage of net sales, as the Company continues to make strategic investments to enhance brand awareness and support its various business channels while improving marketing efficiencies. The Company also remains committed to maintaining a steady investment in research and development throughout 2025 to drive future innovation. General and administrative expenses are expected to increase by approximately $7.0 to $8.0 million, primarily due to share-based compensation and investments in business growth and the absence of a $3.5 million royalty expense reversal that occurred in 2024.

Non-GAAP Financial Information:
To supplement Niagen Bioscience’s unaudited financial data presented in accordance with generally accepted accounting principles (GAAP), the Company has presented Adjusted EBITDA, a non-GAAP financial measure. Niagen Bioscience believes the presentation of this non-GAAP financial measure provides important supplemental information to management and investors and enhances the overall understanding of the Company’s historical and current financial operating performance. The Company believes disclosure of the non-GAAP financial measure has substance because the excluded expenses are infrequent in nature, are variable in nature or do not represent current cash expenditures. Further, such non-GAAP financial measure is among the indicators the Company uses as a basis for evaluating the Company’s financial performance as well as for planning and forecasting purposes. Accordingly, disclosure of this non-GAAP financial measure provides investors with the same information that management uses to understand the Company’s economic performance year-over-year.
Adjusted EBITDA is defined as net income (loss) before (a) interest, (b) provision for income taxes, (c) depreciation, (d) amortization, (e) non-cash share-based compensation costs, (f) severance and restructuring expense and (g) other infrequent items, including the reversal of previously accrued royalties and license maintenance fees, and the recovery of previously recognized credit losses from a legal settlement. While Niagen Bioscience believes that this non-GAAP financial measure provides useful supplemental information to investors, there are limitations associated with the use of such measure. This measure is not prepared in accordance with GAAP and may not be directly comparable to similarly titled measures of other companies due to potential differences in the method of calculation. Management compensates for these limitations by relying primarily on the Company’s GAAP results and by using Adjusted EBITDA only supplementally and by reviewing the reconciliation of the non-GAAP financial measure to its most comparable GAAP financial measure.
Non-GAAP financial measures are not prepared in accordance with, or an alternative for, generally accepted accounting principles in the United States. The Company’s non-GAAP financial measure is not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP.
