Raising full year 2025 revenue outlook to 22% to 27% year-over-year growth
 
LOS ANGELES, CA - August 6, 2025 - Niagen Bioscience, Inc. (NASDAQ:NAGE) today announced financial results for the second quarter of 2025.
Second Quarter 2025 Financial Highlights Compared to Prior Year Period
Total net sales increased 37% to $31.1 million, with Tru Niagen® sales reaching $22.7 million, growing 22%.
Niagen® ingredient sales increased 135% to $7.4 million including food-grade and pharmaceutical-grade.
Gross margin increased 480 basis points to 65.0%.
Sales and marketing expense as a percentage of net sales was 26.4%, an improvement of 420 basis points.
Net income of $3.6 million or $0.05 earnings per share, up from breakeven in prior year quarter.
Adjusted EBITDA, a non-GAAP measure, increased 221% to $5.0 million.
Total cash provided by operations of $9.1 million during the six months ended June 30, 2025, ending the quarter with $60.5 million in cash.
Increased full year 2025 outlook: Net sales growth expected between 22%–27% (previously between 20%–25%), reflecting continued execution and leadership in the expanding NAD+ market.
Recent Operational Highlights
On June 9, 2025, the Company announced the publication of the first peer-reviewed clinical study of Niagen® in individuals with Werner syndrome, a rare premature aging disorder in Aging Cell. The 52-week randomized trial showed Niagen® significantly increased NAD+ levels and improved clinical markers of cardiovascular and skin health, supporting further investigation in rare, age-related diseases.
On July 8, 2025, the Company entered into a worldwide exclusive license agreement with Haukeland University Hospital in Bergen, Norway, securing proprietary rights to develop and commercialize its patented nicotinamide riboside (Niagen®) as a potential pharmaceutical therapy for Parkinson’s disease (PD). This agreement includes access to extensive clinical data, including from the Phase III NOPARK trial, and supports the Company’s broader efforts to advance regulated therapeutic applications for neurodegenerative conditions.
During June 2025, patient dosing the Phase III NOPARK trial was completed, the largest and most comprehensive clinical study of NAD+ augmentation in persons with early PD to date. NOPARK is a randomized, double-blind, placebo-controlled phase III clinical trial featuring 400 individuals with early-stage PD across 12 sites in Norway. Randomized to receive either 500 mg of nicotinamide riboside (Niagen) twice daily or placebo for 52 weeks, participants had follow-up assessments at five time points in a one-year period. The primary endpoint is the MDS-UPDRS total score, a gold standard measure of PD progression. Data analysis is underway and the data from this phase 3 trial is expected to be published in 2026.
On July 14, 2025, the Company announced the launch of Tru Niagen® as an exclusive in-room amenity, and introduced Niagen IV at The Spa by Equinox Hotel New York through NutriDrip, marking Niagen Bioscience’s entry into luxury hospitality. While featured at a single location, Equinox’s sole hotel property, the launch aligns with a premium, health-conscious demographic and serves as a potential model for broader hospitality partnerships.
As of August 2025, Niagen Plus products, including Niagen IV and injectables, are available in over 800 leading wellness clinics in the U.S., up from more than 475 clinics in December 2024. This growth reflects accelerating adoption by clinics and rising demand for clinically administered NAD+ solutions. Niagen Plus products are compounded and distributed through U.S. FDA-registered 503B outsourcing facilities and offered exclusively by prescription through participating wellness clinics.
“We delivered an excellent second quarter, with $31.1 million in net sales, up 37% year-over-year, and $3.6 million in net income,” said Niagen Bioscience CEO Rob Fried. “As the pioneers of this blossoming NAD+ market, we continue to invest in the future while maintaining our focus on profitable growth."

Results of operations for the three months ended June 30, 2025 compared to the prior year quarter

Net Sales for Niagen Bioscience increased 37%, or $8.4 million, to $31.1 million. The growth in net sales was driven by combined growth in Tru Niagen® sales and Niagen® ingredient sales, including strong e-commerce channel performance, stronger demand for food-grade Niagen® and the ramp-up of pharmaceutical-grade Niagen® sales, which were not sold in the prior year quarter.
Gross Margin improved 480 basis points to 65.0% primarily due to changes in product mix, business mix, the use of lower-cost inventory purchases, and improvements in labor and overhead utilization rates with higher sales. These gross margin improvements may not be indicative of future performance and certain drivers, such as lower-cost inventory purchases, are likely to be temporary in nature. Gross margins are expected to normalize in future periods.
Operating Expense increased 22%, or $3.1 million, to $17.0 million reflecting investments for business growth and brand awareness.
Selling and marketing expense increased $1.2 million, and improved 420 basis points as a percentage of net sales to 26.4% of net sales, reflecting improved sales efficiency and disciplined investment. The increase in expenses primarily reflects higher investments to support brand growth in our consumer products segment.
General and administrative expense increased $1.6 million, or 28%, primarily driven by higher employee-related expenses, share-based compensation, and professional and consulting fees.
Research and development expenses increased $0.3 million due to higher professional and consulting fees, as well as higher employee-related expenses.
Net Income was $3.6 million, or $0.05 per share, compared to approximately break-even net loss and loss per share for the second quarter of 2024.
Adjusted EBITDA, a non-GAAP measure, was $5.0 million, up from $1.6 million for the second quarter of 2024. See “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of non-GAAP Adjusted EBITDA to net income (loss), the most directly comparable GAAP measure.
Cash Flows from Operating Activities had a net cash inflow of $9.1 million for the six months ended June 30, 2025 compared to approximately break-even cash flows in the prior year. The approximately $9.1 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 is revising its revenue growth expectation from 20% to 25% year-over-year to 22% to 27%. This outlook reflects anticipated continued expansion of the Company’s e-commerce business as well as growth through new and established partnerships. Gross margin is expected to improve slightly year-over-year compared to 61.8% in 2024, driven by ongoing supply chain optimization efforts, cost savings initiatives, and overall business scale. The Company is also updating its outlook for sales and marketing expenses. These costs are now expected to increase in absolute dollars compared to $29.5 million in 2024, but decrease as a percentage of net sales compared to 29.6% of net sales in 2024. This compares to the prior guidance of an increase in absolute dollars with a stable percentage of net sales year over year. The updated projection reflects the Company’s continued strategic investments to enhance and strengthen brand awareness and support its various business channels while enhancing efficiencies. The Company remains committed to maintaining steady investments in research and development throughout 2025, with spending expected to align closely with fiscal year 2024 levels ($6.0 million), to continue driving 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.

Q2 2025 vs Q2 2024 Key P&L Metrics (in thousands) Q2 2025 Q2 2024 Notes Net Sales $31,117 $22,739 Tru Niagen® and Niagen® ingredient business up 22% and 135%, respectively, driven by strong E-commerce performance, higher demand from key food- grade Niagen® partners and the ramp up of pharmaceutical-grade Niagen®, which were not sold in the prior year quarter. Gross Profit % of Net Sales 20,226 65.0% 13,693 60.2% Up 480bps primarily driven by changes in product mix, business mix, the use of lower-cost inventory purchases, and improvements in labor and overhead utilization rates with higher sales. These factors may not recur, and we expect margins to normalize in future periods. Sales and Marketing % of Net Sales 8,207 26.4% 6,969 30.6% Increased investments, with improved efficiency, driven by strong E- commerce performance and higher ingredient sales, which require minimal minimal sales and marketing support. Research and Development 1,567 1,316 Slightly higher R&D expenses in current period, driven by increased professional fees and employee wages. General and Administrative 7,267 5,664 Up due to higher employee-related expenses, share-based compensation, consulting fees, and other general administrative costs. Total Operating Expense 17,041 13,949 Greater investments, primarily within sales and marketing and general and administrative expenses. Operating Income (Loss) $3,185 $(256) Reflects strong net sales growth and gross margins, partially offset by higher operating expense. 10


 
Adjusted EBITDA Summary In Q2 2025, Adjusted EBITDA grew to $5.0 million, up from $1.6 million in the prior year quarter, driven by continued net income improvement, partially offset by lower severance and restructuring expense. 11 (1) The reversal of royalties and fees relates to a supplemental agreement with Dartmouth, which waived certain obligations under the exclusive license agreements. (2) The recovery of credit losses stems from the 2024 legal settlement with Elysium Health, LLC, paid in two installments, reversing a bad debt write-off from 2019.
