Bolt Biotherapeutics is a clinical-stage biopharmaceutical company dedicated to developing novel immunotherapies for the treatment of cancer. Founded in 2015, the company has made significant strides in advancing its proprietary Boltbody ISAC platform, which combines tumor-targeting antibodies with immune-stimulating linker-payloads to harness the body's own immune system in the fight against cancer.
Business Overview and History
Bolt Biotherapeutics was established in 2015 with a mission to revolutionize cancer treatment through the development of innovative immunotherapies. Since its inception, the company has focused primarily on organizing and staffing, business planning, licensing, developing intellectual property, raising capital, developing product candidates, and conducting preclinical studies and clinical trials.
Prior to its initial public offering in February 2021, Bolt Biotherapeutics funded its operations primarily through private placements of convertible preferred stock, raising gross proceeds of $173.7 million. The IPO marked a significant milestone for the company, raising approximately $242 million in net proceeds and providing additional funding to advance its pipeline of novel immunotherapies.
Throughout its history, Bolt Biotherapeutics has faced various challenges. In 2020, the company incurred $11.7 million in unusual items, which negatively impacted its financial results. The following year, in 2021, Bolt reported a net loss of $98.6 million as it continued to invest heavily in research and development. Despite these setbacks, the company has made progress in advancing its pipeline, including the Boltbody ISAC platform and product candidates targeting Dectin-2 and Claudin 18.2.
In recent years, Bolt Biotherapeutics has continued to report substantial net losses as it progressed its clinical trials and other development activities. To strengthen its balance sheet, the company raised additional capital through a stock sale to Genmab in 2021 and maintained a shelf registration and at-the-market equity offering program. However, it's important to note that Bolt has yet to generate any revenue from product sales, with all of its revenue to date coming from its various collaboration agreements.
The company's pipeline now includes two lead candidates: BDC-3042, a Dectin-2 agonist antibody, and BDC-4182, a next-generation Boltbody ISAC targeting Claudin 18.2. BDC-3042 has received IND clearance from the FDA and is currently in a Phase 1 dose-escalation study in patients with a broad range of solid tumors. BDC-4182, Bolt Biotherapeutics' newest clinical candidate, is currently in IND-enabling activities and is expected to enter the clinic in 2025.
Financials
Bolt Biotherapeutics' financial position has remained relatively stable over the past few years, with a focus on prudent capital management and strategic prioritization of its clinical pipeline. As of September 30, 2024, the company had a cash, cash equivalents, and marketable securities balance of $84.4 million, which it believes will be sufficient to fund its key milestones through mid-2026.
For the fiscal year 2023, Bolt Biotherapeutics reported revenue of $7.88 million. The company incurred a net loss of $69,197,000 for the same period. Operating cash flow (OCF) and free cash flow (FCF) for 2023 were negative $69,525,000 and negative $69,731,000, respectively.
In the most recent quarter (Q3 2024), the company reported revenue of $1,141,000, a decrease compared to the same quarter in the prior year. This decrease was primarily due to no revenue being recognized from the Innovent collaboration as the company had satisfied its performance obligation in the prior quarter, partially offset by increased revenue recognized from the company's other collaborations. The net loss for Q3 2024 was $15,176,000, with OCF of negative $13,966,000 and FCF of negative $14,007,000.
The decrease in net income, OCF, and FCF compared to the same quarter in the previous year was primarily due to the company's continued research and development expenses and the restructuring charges recorded in the current quarter. For the nine months ended September 30, 2024, Bolt Biotherapeutics reported collaboration revenue of $7.7 million, a 33% increase compared to the same period in 2023, driven by continued progress in the company's collaborations.
Liquidity
The company's current ratio, a measure of short-term liquidity, stood at 3.16 as of September 30, 2024, indicating a strong ability to meet its short-term obligations. The quick ratio, which excludes inventories, was also a robust 3.16, reflecting the company's reliance on its cash and liquid investments rather than inventory to cover its current liabilities.
Bolt Biotherapeutics' debt ratio, calculated as total liabilities divided by total assets, was 0.34 as of September 30, 2024, suggesting a relatively low level of leverage. The company's debt-to-equity ratio, a measure of financial leverage, was 0.25, further demonstrating its conservative approach to financing its operations.
Financial Performance and Outlook
Bolt Biotherapeutics' revenue has primarily been derived from its collaboration agreements with partners like Toray, Genmab, and Innovent. These collaborations involve Bolt licensing its Boltbody ISAC technology platform and providing research and development services to the partners.
The Toray collaboration, entered into in 2019, focuses on jointly developing and commercializing a Boltbody ISAC containing Toray's proprietary antibody to treat cancer. Toray provided Bolt an upfront payment and is funding Bolt's research and development activities through the completion of the first Phase 1 clinical trial.
Bolt's 2021 collaboration with Genmab involves evaluating Genmab's antibodies and bispecific antibody engineering technologies in combination with Bolt's Boltbody ISAC platform, with the goal of discovering and developing next-generation bispecific ISACs for cancer treatment. Genmab provided an upfront payment and is funding Bolt's research and development work under this collaboration.
The Innovent collaboration, entered into in 2021 and amended in 2024, has leveraged Innovent's antibody portfolio and discovery capabilities together with Bolt's Boltbody technology to create new cancer treatment candidates. The amended agreement in 2024 resulted in a one-time payment to Bolt and gave Bolt exclusive worldwide rights to ISAC programs utilizing certain Innovent antibodies.
For the nine months ended September 30, 2024, the company's net loss was $47.2 million, compared to a net loss of $51.3 million in the same period of 2023. The reduction in net loss was primarily due to the company's restructuring plan announced in May 2024, which included a 50% reduction in its workforce, as well as the recognition of a one-time payment of $4.7 million from Innovent under the amended collaboration agreement.
Looking ahead, Bolt Biotherapeutics remains focused on advancing its pipeline and achieving key milestones. The company expects to initiate the first-in-human clinical trial for its Claudin 18.2-targeting Boltbody ISAC candidate, BDC-4182, in the second quarter of 2025. Additionally, the company continues to enroll patients in the Phase 1 dose-escalation study for BDC-3042, its Dectin-2 agonist antibody program.
