Day One Biopharmaceuticals, Inc. (DAWN): History, Ownership, Mission, How It Works & Makes Money

Day One Biopharmaceuticals, Inc. (DAWN) is a commercial-stage biotech, but how does a company founded to address the dire lack of therapies for pediatric cancer project a full-year $140 million to $150 million revenue for the 2025 fiscal year?

The core of that growth is their flagship drug, OJEMDA™ (tovorafenib), which alone delivered $30.5 million in net product revenue in Q1 2025, plus a sharp focus on first-in-class targeted therapies for life-threatening diseases.

Considering their November 2025 move to acquire Mersana Therapeutics, expanding their oncology pipeline, you have to ask: is this a shrewd strategic play to diversify or a defintely costly overreach in a volatile biotech market?

Day One Biopharmaceuticals, Inc. (DAWN) History

You want to understand the foundation of Day One Biopharmaceuticals, Inc. (DAWN), and honestly, it's a remarkably fast-moving story of targeted oncology. The company was purpose-built to address the innovation gap in pediatric cancer, and its trajectory from a concept in 2018 to a commercial-stage company by 2024 is a masterclass in focused execution. They cut straight to a solution for a critical unmet need.

Given Company's Founding Timeline

Year established

Day One Biopharmaceuticals, Inc. was incorporated in 2018 on October 31.

Original location

The company was originally based in San Francisco, California, specifically in South San Francisco, before establishing its headquarters in Brisbane, California.

Founding team members

The company was founded by Julie Grant and Samuel Blackman, leveraging expertise in venture capital and oncology development.

Initial capital/funding

While the initial seed capital is not public, the company's first major funding event was a $60 million Series A round announced in May 2020. This capital was immediately put to work acquiring their lead asset.

Given Company's Evolution Milestones

Given Company's Transformative Moments

The company's history is defined by a few high-impact, deliberate decisions that accelerated its path to market, skipping the typical decade-long slog for a de novo biotech.

• Acquiring Tovorafenib: The decision to acquire tovorafenib (DAY101) from Takeda in 2020 was the single biggest move. It meant starting with a clinical-stage asset, dramatically shortening the timeline to FDA approval and commercialization.
• The IPO Fuel: The $160.0 million raised in the May 2021 IPO was crucial. That capital funded the pivotal Phase 2 FIREFLY-1 trial, which ultimately led to the accelerated approval of OJEMDA.
• Commercial Transition: The April 2024 FDA accelerated approval of OJEMDA for pediatric low-grade glioma (pLGG) was the pivot point. It immediately changed the company from a research expense center to a revenue-generating commercial entity. This shift is reflected in the 2025 year-to-date U.S. OJEMDA net product revenue of $102.6 million through the third quarter.
• 2025 Pipeline Expansion: In November 2025, Day One signed a definitive merger agreement to acquire Mersana Therapeutics. This strategic move, valued up to ~$285 million (with an approximate equity value at closing of $129 million), adds another clinical-stage asset, emiltatug ledadotin, to the pipeline, showing a clear intent to broaden their oncology focus beyond pLGG.

The company ended the third quarter of 2025 with a strong balance sheet, holding $451.6 million in cash, cash equivalents, and short-term investments, which gives them plenty of dry powder to execute on this expanded pipeline, defintely a realist approach to growth.

Day One Biopharmaceuticals, Inc. (DAWN) How It Works

Day One Biopharmaceuticals, Inc. operates as a commercial-stage biopharmaceutical company by identifying, acquiring, and developing targeted therapies for genetically defined cancers, primarily focusing on pediatric oncology. It generates revenue through the commercial sales of its flagship approved therapy while simultaneously advancing a focused pipeline of novel oncology candidates to address high unmet medical needs in both children and adults.

Day One Biopharmaceuticals' Product/Service Portfolio

The company's commercial success in 2025 is anchored by its first approved product, while its near-term growth is tied to integrating and advancing newly acquired, promising assets like emiltatug ledadotin (Emi-Le).

Day One Biopharmaceuticals' Operational Framework

The operational process is a dual-track model: efficient commercialization of an approved asset and fiscally disciplined pipeline development, which is critical for a biotech focused on rare, high-need cancers. The full-year 2025 net product revenue guidance was raised to between $145 million and $150 million, demonstrating strong commercial execution.

Here's the quick math: Q3 2025 net product revenue grew 15% over the prior quarter, driven by a 19% rise in new patient starts, so the commercial engine is running well.

• Search & Development Strategy: Actively identifies, in-licenses, and acquires potential best- or first-in-class targeted cancer treatments, exemplified by the acquisition of Mersana Therapeutics for up to $285 million.
• Targeted Drug Development: Focuses on genetically defined cancers, which allows for smaller, more efficient clinical trials (like the registrational FIREFLY-1 study) and a clearer path to regulatory approval in high-unmet-need populations.
• Specialty Commercialization: Engages a specialized commercial team to manage the unique distribution and patient support needs for an orphan drug like OJEMDA in the pediatric oncology community.
• Disciplined Capital Allocation: Maintains a balanced approach to investment, evidenced by reduced R&D expenses to $31.4 million in Q3 2025, while still funding key clinical trials like the Phase 3 FIREFLY-2 trial.

Day One Biopharmaceuticals' Strategic Advantages

The company's market position rests on its first-mover advantage in a niche market, a strong balance sheet, and a clear, focused strategy that resonates with the patient community. You can read more about their core philosophy here: Mission Statement, Vision, & Core Values of Day One Biopharmaceuticals, Inc. (DAWN).

• First-in-Class Market Position: OJEMDA is the first approved Type II RAF inhibitor for pLGG, establishing Day One Biopharmaceuticals as a leader in treating this specific, devastating pediatric brain tumor.
• Financial Runway: Ended Q3 2025 with a strong cash position of $451.6 million in cash, cash equivalents, and short-term investments, providing a defintely solid buffer for continued R&D and commercial expansion without immediate reliance on volatile capital markets.
• Focused Expertise: Deep specialization in pediatric and rare adult cancers allows them to efficiently navigate complex regulatory pathways and build credibility with a highly specialized physician base.
• Pipeline Diversification via M&A: The strategic acquisition of Emi-Le diversifies the pipeline beyond kinase inhibitors into the high-growth Antibody-Drug Conjugate (ADC) space, targeting a new, aggressive cancer (ACC-1) with no approved therapies.

Day One Biopharmaceuticals, Inc. (DAWN) How It Makes Money

Day One Biopharmaceuticals, Inc. generates nearly all its revenue by selling its flagship product, OJEMDA (tovorafenib), a targeted therapy for pediatric low-grade glioma (pLGG), a type of brain tumor. The company also earns a small, but volatile, amount from licensing agreements related to its pipeline assets.

Day One Biopharmaceuticals, Inc.'s Revenue Breakdown

The financial engine is overwhelmingly focused on product sales, which is a sign of a successful commercial launch. Here's the quick math on the revenue streams based on the Q3 2025 results, which brought in a total of $39.8 million.

Product revenue is the real story here, growing 15% quarter-over-quarter in Q3 2025, which is a strong signal of market adoption. License revenue, however, is not a sustainable growth driver; it plummeted from $73.7 million in Q3 2024 to just $1.3 million in Q3 2025, reflecting the lumpy nature of one-time deals.

Business Economics

The economics of Day One Biopharmaceuticals, Inc. are now shifting from a pre-commercial, research-heavy model to a commercial one, which is a major inflection point. You need to watch three things: adoption, pricing, and cost control.

• Pricing Power: The company operates in the ultra-specialized oncology market, treating a rare, life-threatening disease (pLGG). This niche focus allows for premium pricing, which is standard for novel biopharma therapies.
• Gross-to-Net (GTN) Adjustment: This is the discount between the list price and the net price the company actually receives. Day One Biopharmaceuticals, Inc. guided for a 2025 GTN in the 12% to 15% range, at the high end, partly due to a price increase in July. A lower GTN means more revenue per sale, which is defintely a positive.
• Operating Leverage: In Q3 2025, the net product revenue from OJEMDA exceeded the combined cost of sales and selling, general, and administrative (SG&A) expenses for the first time. This is the moment the commercial model starts to scale and cover its own operating costs.
• Commercial Momentum: New patient starts for OJEMDA accelerated by almost 20% in Q3 2025 compared to Q2 2025, showing deepening prescriber confidence and a clear path to becoming the standard of care for relapsed/refractory pLGG.

The company is strategically expanding its portfolio, too, recently announcing the acquisition of Mersana Therapeutics for up to $285 million to bring in a new oncology asset, emiltatug ledadotin (Emi-Le). This shows a realist approach to pipeline growth, not just relying on one drug.

Day One Biopharmaceuticals, Inc.'s Financial Performance

While the commercial performance is strong, the company is still in a net loss position as it invests heavily in R&D for future indications and pipeline expansion. You must balance the top-line growth against the bottom-line burn.

• 2025 Revenue Guidance: Management raised its full-year 2025 net product revenue guidance for OJEMDA to a range of $145 million to $150 million, reflecting continued strong demand.
• Cash Runway: Day One Biopharmaceuticals, Inc. ended Q3 2025 with a robust cash position of $451.6 million in cash, cash equivalents, and short-term investments, with no debt. This cash balance provides a long runway to fund operations and the ongoing clinical trials, like the Phase 3 FIREFLY-2 trial.
• Net Loss: The net loss for Q3 2025 was $19.7 million, a significant shift from the net income in the prior year, primarily due to the non-recurrence of large license revenue payments. This loss is expected as R&D and SG&A expenses totaled $59.5 million for the quarter.

The key takeaway is that the core business-OJEMDA sales-is performing and scaling, but the overall enterprise remains in investment mode. For a deeper dive into the company's long-term vision, you can read the Mission Statement, Vision, & Core Values of Day One Biopharmaceuticals, Inc. (DAWN).

Day One Biopharmaceuticals, Inc. (DAWN) Market Position & Future Outlook

Day One Biopharmaceuticals is a commercial-stage biotech company with a dominant position in the niche market of pediatric low-grade glioma (pLGG) treatment, driven by its flagship drug OJEMDA (tovorafenib). Its future trajectory hinges on expanding OJEMDA into the frontline setting and successfully integrating a new pipeline asset from the recent Mersana Therapeutics acquisition.

The company is on track for significant top-line growth, with raised full-year 2025 net product revenue guidance for OJEMDA at $145 million to $150 million. This momentum is defintely a strong signal, but the company must convert its clinical pipeline into new approvals to sustain long-term value.

Competitive Landscape

In the targeted pediatric oncology space, competition is fierce but highly segmented by specific genetic mutations. Day One's core advantage is OJEMDA's broad label in the relapsed/refractory setting, which captures a much larger portion of the BRAF-altered pLGG market than its primary competitor.

Opportunities & Challenges

The near-term focus is clear: expand the use of OJEMDA and diversify the pipeline. The acquisition of Mersana Therapeutics is a bold move to enter the solid tumor space, but it introduces new execution risks.

Industry Position

Day One Biopharmaceuticals holds a unique position as a high-growth, commercial-stage biotech focused on a critical unmet need in pediatric oncology. They are not a major pharmaceutical powerhouse yet, but they dominate their specific niche.

• Niche Dominance: OJEMDA's approval for relapsed/refractory BRAF-altered pLGG provides a near-monopoly in the most common childhood brain tumor's molecularly defined sub-segment. They're the first to market for the majority of these patients.
• Financial Strength: The company's Q3 2025 cash balance of $451.6 million is robust, giving them a significant runway to fund operations and the up to $285 million Mersana deal without immediate dilution risk. That's a strong position for a biotech.
• Pipeline Catalyst: The Mersana acquisition, adding Emi-Le, shifts the narrative from a single-asset pediatric-focused company to a broader targeted oncology player, targeting a new adult solid tumor (ACC-1) with a high unmet need and no approved therapies.
• Market Valuation: The stock trades at a price-to-sales ratio that is favorable compared to the broader biotech industry average, suggesting the market is valuing its future growth potential, especially with the Phase 3 FIREFLY-2 data expected soon.
