Rhea-AI Filing Summary

Form 4 filed 08/01/2025 details insider activity at CCC Intelligent Solutions Holdings (CCCS). Executive Vice President & Chief Product and Technology Officer John P. Goodson vested previously granted restricted stock units (RSUs) on 07/30/2025.

• 21,875 common shares acquired at $0 (Code M) through automatic RSU conversion.
• 9,560 shares sold at $9.78 (Code F) to cover tax-withholding obligations.

The transactions are routine, reflect no open-market purchase or discretionary sale, and modestly increase insider equity exposure, offering a neutral-to-slightly-positive alignment signal for shareholders.

Positive

• Net addition of 12,315 shares to insider’s direct stake, modestly improving management–shareholder alignment.

Negative

• 9,560 shares sold (withholding) dampens bullish interpretation and provides no open-market confidence signal.

Insights

Securities Analyst

TL;DR: Routine RSU vesting; insider stake up 6%, no open-market buying—neutral signal.

The filing records automatic conversion of 21,875 RSUs and a tax-related sale of 9,560 shares. Net ownership rises to 200,009 shares, roughly a 6% increase. Because Code M and Code F are administrative, the action doesn’t indicate active bullish or bearish sentiment. Lack of open-market buying limits positive read-through, yet the higher absolute holding still marginally aligns management with investors.

Corporate Governance Specialist

TL;DR: Standard Rule 10b5-1 compliant vesting; governance risk unchanged.

The RSUs vest under a predetermined four-year schedule tied to July 30, 2021, consistent with prior grants and disclosure. Settlement choices remain at issuer discretion, indicating flexible compensation policy but no red flags. With no remaining derivative positions and limited share disposal, the event is non-impactful to governance posture or float.

DEREGISTRATION OF SECURITIES

This Post-Effective Amendment to the following Registration Statements on Form S-3 (each, a “Registration Statement” and collectively, the “Registration Statements”), previously filed with the U.S. Securities and Exchange Commission (the “SEC”), is being filed by Sage Therapeutics, Inc., a Delaware corporation (“Sage”), to remove and withdraw from registration all securities registered pursuant to the Registration Statements that remain unissued and unsold:

· Registration Statement on Form S-3 (File No. 333-282162), originally filed with the SEC on September 17, 2024, registering issuance and sale by Sage of up to $250,000,000 in aggregate offering price of Sage’s common stock, par value $0.0001 per share (“Common Stock”) for issuance and sale from time to time under a sales agreement with TD Securities (USA) LLC; as amended with the Post-Effective Amendment No. 1, filed with the SEC on February 11, 2025 to disclose that Sage no longer qualified as a well-known seasoned issuer (as such term is defined in Rule 405 under the Securities Act) upon the filing by Sage with the SEC on February 11, 2025 of its Annual Report on Form 10-K for the year ended December 31, 2024; as further amended with the Post-Effective Amendment No. 2, filed with the SEC on February 11, 2025 to convert the Registration Statement to the proper EDGAR submission type for a non-automatic shelf registration and to register for issuance and sale of an indeterminate number of securities of up to $400,000,000 in aggregate offering price, including shares of Common Stock of up to $250,000,000 in aggregate offering price previously registered on September 17, 2024 that may be issued and sold under an amended and restated sales agreement with TD Securities (USA) LLC, and any additional securities that may be offered or issued pursuant to Rule 416 under the Securities Act of 1933.

· Registration Statement on Form S-3 (File No. 333-261708), originally filed with the SEC on December 17, 2021, registering the issuance and sale by Sage of an indeterminate amount of securities as may from time to time be offered thereunder at indeterminate prices, including Sage’s Common Stock, preferred stock, debt securities, warrants and units, by Sage and for resale by certain shareholders at prices and on terms determined at the time of offering.
