Akebia (AKBA) CFO Erik Ostrowski Receives Stock Award and Options

What Happened

Erik Ostrowski, SVP, Chief Financial Officer, Chief Business Officer & Treasurer of Akebia Therapeutics, was granted two awards on January 30, 2026: 204,000 restricted stock units (RSUs) and 320,000 stock options. Both grants are reported as acquisitions at $0.00 (no cash paid at grant).
The RSUs and options were awarded under Akebia’s 2023 Stock Incentive Plan. The filing reports these as awards (transaction code A), not purchases or sales.

Key Details

Transaction date: 2026-01-30; filing date (Form 4): 2026-02-03 (filed within the standard two-business-day window).
Grant amounts and reported price: 204,000 RSUs @ $0.00; 320,000 options (derivative grant) @ $0.00.
Shares owned after transaction: Not specified in the provided filing excerpt.
Footnotes:
- RSU vesting (F1): 1/3 vests on each of the first, second and third anniversaries of the grant, subject to continued service.
- Option vesting (F2): Options vest over four years — 25% after one year, then the remaining 75% in equal quarterly installments, subject to continued service.
No indication of exercise or sale of shares; these are grants (not exercises or transfers).

Context

These grants are compensation awards and do not reflect an immediate cash purchase or sale; they become valuable only as they vest and, for options, if the strike price (not listed in this filing excerpt) is favorable relative to market price at exercise.
For retail investors, awards are routine executive compensation and should be interpreted as part of pay structure rather than a direct bullish or bearish trade by the insider.
