Serve Robotics Inc. (SERV) � Form 4 insider transaction
Chief Financial Officer Brian Read disclosed the sale of 1,212 SERV common shares on 30-Jul-2025 at a weighted-average price of $10.457. The shares were sold solely to cover federal and state tax-withholding obligations triggered by the vesting and settlement of restricted stock units (RSUs), as noted in Footnote 1. After the transaction, Read directly owns 396,266 shares.
No derivative securities were bought or sold, and the filing shows no 10b5-1 plan or other pre-arranged trading program. The disposition equals roughly 0.3 % of the executive’s reported holdings, suggesting the officer retains the vast majority of his equity exposure. The document contains no financial metrics, operational updates, or strategic commentary beyond the routine administrative sale.
White Hat Capital group filed Amendment No. 4 to its Schedule 13D on Comtech Telecommunications (CMTL) dated 21 Jul 2025. The group � six affiliated funds plus principals David J. Chanley and Mark R. Quinlan � now reports beneficial ownership of up to 4.81 million shares, or 9.99 % of the 29.4 million shares outstanding. Holdings include 4.40 million shares issuable on conversion of Series B-3 preferred stock and 54,655 RSUs. A 9.99 % “Blocker� in the preferred certificate prevents further conversions that would push ownership above that threshold.
The disclosure responds to the issuer’s Amendment No. 2 to its Subordinated Credit Agreement executed 21 Jul 2025, which materially revises the capital structure:
- Introduces a $35 million incremental priority subordinated unsecured term loan (extended by lenders other than White Hat) that ranks senior to existing subordinated loans.
- Interest accrues paid-in-kind monthly at the greater of the senior term-loan rate or Term SOFR + 10.5 %; no make-whole premium.
- Suspends fixed-charge coverage, net-leverage and minimum EBITDA covenant tests until the four-quarter period ending 31 Jan 2027.
- Lowers minimum quarterly average liquidity to $15 million (from $17.5 million).
- Resets stepped minimum EBITDA covenant: $26 m (Q4 FY27) rising to $32 m from Q4 FY27 onward.
- Permits a specified asset disposition and requires management incentive/retention plans.
No share transactions were effected by the reporting persons in the past 60 days.
Karyopharm Therapeutics Inc. (Nasdaq: KPTI) filed a Form 8-K on 11-Jul-2025 detailing material liquidity and operational actions.
The company disclosed that it held confidential discussions with new and existing investors to extend its cash runway; however, no financing agreement has been reached. To comply with confidentiality agreements, it published the related investor presentation (the �Cleansing Materials�) as Exhibit 99.1.
The Board is actively evaluating strategic alternatives that could include a merger or sale of the company, in- or out-of-court restructurings, or refinancing of existing debt. Management cautions that there is no assurance any transaction will occur or what terms might apply.
To conserve cash, Karyopharm is implementing a 20 % workforce reduction, with one-time charges expected to be immaterial. The company intends to keep supporting commercial sales of XPOVIO for multiple myeloma and to advance ongoing Phase 3 trials in myelofibrosis and endometrial cancer.
The filing reiterates forward-looking risk factors, including substantial doubt about the company’s ability to continue as a going concern absent additional capital.
