Bolt Biotherapeutics, Inc. (BOLT) filed an SEC Form 8-K — Results of Operations and Financial Condition. Exhibit 99.1 Bolt Biotherapeutics Reports Third Quarter 2026 Financial Results and Provides Business Update • Completed acquisition of Prana Therapies and $120 million concurrent private placement financing, establishing PRA-216 and the INSPIRE-built pipeline as Bolt’s primary de
How this was made
The 30-second read
Why it matters
The capital raise and acquisition are expected to extend cash runway to 2028 and accelerate development of the PRA‑216 program, likely supporting the stock.
Market read
Primary disclosure of a sizable financing and strategic acquisition; material for investors and likely to move the stock.
What to watch
Potential regulatory hurdles for the new pipeline and execution risk of Phase 2 studies.
Bolt reports zero collaboration revenue and a $4.7 million Q3 operating loss, while closing the Prana Therapies acquisition and a $120 million private placement that it says fund operations into 2028
Operating expenses and net loss fell sharply year over year, but collaboration revenue was zero, cash and investments are small relative to the operating loss, total stockholders' equity fell from $26,505 thousand to $8,562 thousand, and the company's runway statement depends on the October 2026 financing that was completed after the quarter ended.

Capital returns
- No share repurchases or dividends are reported in the filing.
- Subsequent to quarter end, in October 2026, Bolt sold 13,995.311 shares of Series D Preferred Stock and accompanying warrants for aggregate gross proceeds of $120.0 million, before placement agent fees and other offering expenses. Gross proceeds from the warrants are not included.
- Financing cash flow for the nine months ended September 30, 2026 was $25 thousand, from proceeds from issuance of common stock, against $14 thousand in the prior-year nine months.
What drove it
- The company attributes the R&D decrease to an R&D tax incentive, lower salary and related expenses primarily from its restructuring, and overall lower research and development activities.
- The company attributes the G&A decrease to lower salary and related expenses primarily from its restructuring, as well as lower personnel expenses.
- The company states that collaboration revenue in the comparative periods was generated from services performed under the R&D collaborations as it fulfilled its performance obligations.
- The company reports the October 2026 acquisition of Prana Therapies, a stock-for-stock reverse merger, and the concurrent $120 million private placement, which it says make Prana's PRA-216 program and the INSPIRE pipeline its primary development focus.
- The company reports that the Chesapeake Master Lease was terminated following the Prana acquisition, with an effective lease expiration date of January 1, 2027.
Concerns
- Collaboration revenue was zero in the quarter, against $2,169 thousand in the same quarter of 2025, and nine-month collaboration revenue was $31 thousand, against $5,195 thousand.
- Stockholders' equity fell to $8,562 thousand at September 30, 2026 from $26,505 thousand at December 31, 2025.
- Cash and cash equivalents plus short-term and long-term investments at September 30, 2026 were $13,782 thousand, $1,016 thousand and $247 thousand respectively, against nine-month net cash used in operating activities of $(17,641) thousand.
- The company says the runway into 2028 relies on the October 2026 financing, which closed after the quarter ended.
- The company's forward-looking statements flag the risk that stockholder approvals are not obtained, which would affect realization of the transaction benefits. Stockholder approval of the conversion of the Series D Preferred Stock is still required.
- The company reports an $808 thousand impairment charge in the nine months ended September 30, 2026.
What to watch
- Stockholder approval of the conversion of the Series D non-voting convertible preferred stock into common stock, which the company says it will seek as soon as practicable.
- Expected approximately 34.2 million shares of common stock outstanding on an as-converted basis, before exercise of the PIPE warrants.
- Initial patient proof-of-concept data across the PRA-216 Phase 2 studies in asthma, COPD and atopic dermatitis, which the company expects beginning in the second quarter of 2027, and the planned eosinophilic esophagitis study.
- Entry into the clinic and initial clinical data for a second wholly owned INSPIRE program, which the company expects in 2H 2027.
- Disclosures required under ASC 805, Business Combinations, which the company says it will provide no later than January 8, 2027.
- Whether the company receives proceeds from exercise of the accompanying PIPE warrants, which the filing does not quantify.

Analysis
Bolt reported a third quarter 2026 with no collaboration revenue, against $2,169 thousand in the third quarter of 2025, and the filing states that prior-period revenue came from services performed under its R&D collaborations. Total operating expense fell to $4,730 thousand from $9,872 thousand, with R&D down to $2,209 thousand from $6,535 thousand and G&A down to $2,521 thousand from $3,337 thousand. The company attributes the R&D decline to an R&D tax incentive, lower salary and related costs from its restructuring, and lower activity, and the G&A decline to lower salary costs from the restructuring and lower personnel expenses. The loss from operations narrowed to $(4,730) thousand from $(7,703) thousand, and the net loss to $(4,422) thousand from $(7,144) thousand, or $(2.25) per share against $(3.72).
The nine-month figures show the same pattern with a larger base. Collaboration revenue was $31 thousand against $5,195 thousand, R&D was $12,187 thousand against $23,545 thousand, and G&A was $7,741 thousand against $10,678 thousand. The filing also shows an $808 thousand impairment charge in the nine months, with no comparable charge in the prior year. Net loss for the nine months was $(19,549) thousand, or $(10.09) per share, against $(26,745) thousand, or $(13.94) per share. Net cash used in operating activities was $(17,641) thousand against $(32,694) thousand.
The balance sheet is smaller than a year earlier. Total assets were $35,591 thousand at September 30, 2026 against $56,748 thousand at December 31, 2025, and stockholders' equity was $8,562 thousand against $26,505 thousand. Cash and cash equivalents rose to $13,782 thousand from $11,703 thousand, but short-term investments fell to $1,016 thousand from $15,802 thousand, so the nine-month investing inflow of $19,695 thousand came mainly from maturities of marketable securities. Total liabilities declined to $27,029 thousand from $30,243 thousand.
The defining event of the period is the October 23, 2026 acquisition of Prana Therapies, completed through 430,746 shares of common stock and 16,360.929 shares of Series D non-voting preferred stock, together with a concurrent private placement of 13,995.311 Series D Preferred shares and accompanying warrants for aggregate gross proceeds of $120.0 million before placement agent fees and offering expenses. The company expects approximately 34.2 million common shares outstanding on an as-converted basis before PIPE warrant exercise, subject to stockholder approval of the Series D conversion. The company says the financing funds operations into 2028 through multiple milestones. Because the transaction closed after September 30, 2026, none of its effects appear in the reported quarter balance sheet.
The filing does not include formal financial guidance, so no outlook comparison is possible. The near-term focus is the PRA-216 Phase 2 program, where the company expects patient proof-of-concept data beginning in the second quarter of 2027, and a second wholly owned INSPIRE program expected to enter the clinic and generate initial data in 2H 2027. Investors should weigh the falling operating losses against zero current revenue, the reduced equity base, and the dependence of the stated runway on a financing and a stockholder approval that are still pending.
Management, verbatim
PRA-216 is our flagship program and the first clinical validation of the INSPIRE platform. It is now in Phase 2 development in asthma, COPD and atopic dermatitis, with an additional study planned in eosinophilic esophagitis, and we expect patient proof-of-concept data across all four studies beginning in the second quarter of 2027.
Sheila Gujrathi, M.D., Chief Strategy Officer of Bolt Biotherapeutics
Completing the Prana acquisition marks an important transformation for Bolt. With a strong balance sheet, an advanced clinical program and a differentiated platform, we believe we are well positioned to execute against the important milestones ahead.
Willie Quinn, President and Chief Executive Officer of Bolt Biotherapeutics
