Similarweb Ltd. filings document the reporting obligations of a foreign private issuer whose ordinary shares trade on the NYSE. Its Form 6-K reports furnish quarterly and annual-result materials, shareholder letters, annual general meeting notices, proxy statements, voting results and current governance updates.
The filing record also covers board and finance leadership changes, ordinary-share matters, equity compensation registration references on Form S-8, shelf-registration references on Form F-3 and selected insider share activity. These disclosures connect Similarweb's digital intelligence business with formal reporting on operating results, corporate governance, shareholder approvals and capital-structure administration.
Similarweb Ltd. identifies CEO Michael Akkerman in a Form 3 reporting his beneficial ownership of the issuer’s securities as of the date he became subject to Section 16 reporting requirements.
Similarweb Ltd. supplemented its proxy disclosure on the proposed compensation terms for new Chief Executive Officer Michael Akkerman, adding peer-group benchmarking and clarifying the Compensation Policy’s equity-grant limit.
The compensation peer group has 19 companies, with 11 non-founder CEO peers used for benchmarking. Mr. Akkerman’s cash compensation is positioned at approximately the 25th to 50th percentile of those peers, and his sign-on equity allocation at approximately the 25th percentile. The on-target grant represents approximately 1.25% of the Company’s capitalization on a fully diluted basis; the proposed grant is approximately $10,000,000, with full overachievement of $14,500,000.
The supplement says the proposed grant is within the policy limits it identifies as the higher of $11,000,000 or approximately $14,700,000. It does not change Proposal 1 or the November 16, 2026 meeting. Previously submitted proxies remain valid unless properly revoked or changed, and the Board continues to unanimously recommend voting “FOR” Proposal 1.
Similarweb Ltd. (SMWB) is asking shareholders to approve proposed compensation terms for incoming Chief Executive Officer Michael Akkerman, whose anticipated start date is November 2, 2026. The package includes a $550,000 annual base salary, a target annual bonus of $550,000 tied to goals set by the Board, a $500,000 one-time sign-on bonus earned on the first anniversary of the start date (which may be advanced), and target equity awards with an aggregate grant-date value of approximately $10,000,000, stated as approximately 1.25% of the Company on a fully diluted basis as of the Employment Agreement date.
The equity award comprises approximately $3,000,000 in RSUs, $5,000,000 in operating PSUs tied to revenue and EBITDA targets for FY2027-FY2029, and $2,000,000 in market PSUs tied to share-price milestones over four years; approximately 70% is performance-based. Shareholder approval is required for the compensation terms, but not for the Board’s appointment of Akkerman. If shareholders reject the proposal, the terms will not take effect and the Board must negotiate revised terms. The meeting is scheduled for November 16, 2026.
