Insights

Spruce raises $50.0 million via equity and pre-funded warrants to fund its lead rare-disease program.

Spruce Biosciences agreed to a private placement of 502,181 common shares and pre-funded warrants for up to 233,144 shares at $68.00 per share, targeting gross proceeds of about $50.0 million. This brings in non-dilutive cash relative to debt and is typical financing for a clinical-stage biotech progressing an asset toward registration.

The pre-funded warrants carry a de minimis $0.01 exercise price and a five-year term, with Beneficial Ownership Limitations generally at 9.99% or 4.99%, adjustable up to 19.99% with notice. These caps limit any single holder’s post-exercise stake, which can help manage control and listing considerations while still enabling full eventual share issuance.

Spruce states it intends to use its stronger balance sheet to advance tralesinidase alfa enzyme replacement therapy for Sanfilippo Syndrome Type B toward a biologics license application in the first quarter of 2026 and a potential U.S. commercial launch in late 2026. Subsequent company disclosures may provide more detail on cash runway, development milestones and how this financing aligns with projected regulatory and commercial timelines.

Item 1.01

Entry into a Material Definitive Agreement.

Private Placement

On October 7, 2025, Spruce Biosciences, Inc. (the “Company”) entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors (the “Purchasers”), pursuant to which the Company agreed to sell and issue to the Purchasers (i) 502,181 shares of the Company’s common stock (“Common Stock”) and (ii) pre-funded warrants to purchase up to 233,144 shares of Common Stock (the “Pre-Funded Warrants”) in a private placement transaction (the “Private Placement”). The purchase price per share of Common Stock is $68.00 per share (the “Purchase Price”) and the purchase price for the Pre-Funded Warrants is $67.99, which equals the Purchase Price minus the $0.01 exercise price per Pre-Funded Warrant. The closing of the Private Placement is expected to occur on or about October 9, 2025 (the “Closing”), subject to the satisfaction of customary closing conditions. The total gross proceeds to the Company at the Closing are expected to be approximately $50.0 million.

The Pre-Funded Warrants have a per share exercise price of $0.01 subject to proportional adjustments in the event of stock splits or combinations or similar events. A holder (together with its affiliates and other attribution parties) may not exercise any portion of a Pre-Funded Warrant to the extent that after giving effect to such exercise the holder would own more than 9.99% (or, at the holder’s option upon issuance, 4.99%) of the Company’s outstanding Common Stock immediately after exercise, which percentage may be changed at the holder’s election to a lower or higher percentage not in excess of 19.99% upon 61 days’ notice to the Company subject to the terms of the Pre-Funded Warrants. The Pre-Funded Warrants will be exercisable for a period of five years following the date of issuance.

Leerink Partners, Citizens Capital Markets and H.C. Wainwright & Co. are acting as placement agents for the Private Placement and Oppenheimer & Co. is acting as capital markets advisor (collectively, the “Placement Agents”) for the Private Placement. The Placement Agents are entitled to receive a portion of a combined fee equal to approximately 6.0% of the aggregate gross proceeds from the securities sold at the Closing, plus the reimbursement of certain expenses.

Under the terms of the Purchase Agreement, the Company has agreed to prepare and file, within 20 days after the Closing (the “Filing Deadline”), one or more registration statements with the Securities and Exchange Commission (the “SEC”) to register for resale the Common Stock and Common Stock issuable upon exercise of the Pre-Funded Warrants issued under the Purchase Agreement, and to cause the applicable registration statements to become effective within a specified period after the Filing Deadline. Certain cash penalties will apply to the Company in the event of registration failures, as described in the Purchase Agreement.

The Purchase Agreement contains customary representations, warranties and covenants that were made solely for the benefit of the parties to the Purchase Agreement. Such representations, warranties and covenants (i) are intended as a way of allocating risk between the parties to the Purchase Agreement and not as statements of fact, and (ii) may apply standards of materiality in a way that is different from what may be viewed as material by stockholders of, or other investors in, the Company. Accordingly, the Purchase Agreement is included with this filing only to provide investors with information regarding the terms of transaction and not to provide investors with any other factual information regarding the Company. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or any of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Purchase Agreement, which subsequent information may or may not be fully reflected in public disclosures.

The foregoing is only a summary of the terms of the Purchase Agreement and Pre-Funded Warrants and does not purport to be complete and is qualified in its entirety by reference to (i) the full text of the form of Purchase Agreement, a copy of which is attached to this report as Exhibit 10.1 and (ii) the form of Pre-Funded Warrant to be issued under the Purchase Agreement, a copy of which is attached to this report as Exhibit 4.1.

 

Item 3.02

Unregistered Sales of Equity Securities.

The disclosure regarding the securities to be sold and issued under the Purchase Agreement as set forth under Item 1.01 of this report is incorporated by reference under this Item 3.02.

The securities described above under Item 1.01 have not been registered under the Securities Act of 1933, as amended (the “Securities Act”). The Company relied on the exemption from the registration requirements of the Securities Act by virtue of Rule 506 of Regulation D thereunder. Each of the Purchasers has represented that it is an “accredited investor” as defined in Regulation D of the Securities Act and that it is acquiring the securities for investment only and not with a view towards, or for resale in connection with, the public sale or distribution thereof, and appropriate legends will be affixed to the securities.

 

Item 8.01

Other Events.

The Company intends on advancing tralesinidase alfa enzyme replacement therapy (TA-ERT) for the treatment of Sanfilippo Syndrome Type B (MPS IIIB) through a biologics license application submission in the first quarter of 2026 and potential U.S. commercial launch in late 2026.
