[D] Biofrontera Inc. Warrants SEC Filing

Rhea-AI Filing Summary

SEMrush Holdings, Inc. (ticker SEMR) Chief Financial Officer Brian Mulroy submitted a Form 4 covering an insider transaction dated July 10 2025. The filing records a code “F” transaction, meaning the company withheld shares solely to satisfy tax obligations triggered by the vesting of restricted stock units (RSUs); no open-market sale or purchase occurred.

• Shares withheld: 4,079 Class A common shares
• Reference price: $8.97 per share (closing price on the vesting date)
• Remaining ownership: 903,306 Class A shares held directly, a portion of which remains as unvested RSUs

No derivative securities were exercised, acquired, or disposed of. Ownership status is direct, and the filing was executed by attorney-in-fact David Mason on July 11 2025. Because the activity is routine tax withholding and involves less than 0.5% of the insider’s total holdings, the event is not considered materially market-moving.

Insights

Financial Analyst

TL;DR: Routine RSU tax-withholding; CFO still retains 903k shares—neutral for investors.

The Form 4 shows an automatic share withholding (code F) of 4,079 shares valued at roughly $36.6 k. Such transactions do not reflect discretionary buying or selling and therefore carry limited signalling value. Mulroy’s sizable remaining stake (≈903 k shares) underscores continued alignment with shareholder interests. No derivatives were exercised, and no substantive change in ownership structure occurred. Overall, the filing is administrative and not expected to impact SEMR’s valuation or trading dynamics.

The Securities and Exchange Commission has not necessarily reviewed the information in this filing and has not determined if it is accurate and complete.
The reader should not assume that the information is accurate and complete.
