[SCHEDULE 13D/A] ADECOAGRO S.A. SEC Filing

Rhea-AI Filing Summary

The filed Schedule 13D/A (Amendment No. 13) discloses that Tether Holdings, S.A. de C.V., its subsidiary Tether Investments, S.A. de C.V., and individual reporting person Giancarlo Devasini collectively beneficially own 72,402,171 Adecoagro S.A. (AGRO) common shares. Based on the issuer’s 99,993,156 shares outstanding as of 4 April 2025, the filing represents a 72.4 % ownership stake, giving the group majority voting and dispositive control.

• Voting/Dispositive Power: All reporting persons have shared voting and shared dispositive power over the full share block; none have sole power.
• Citizenship/Organization: Tether entities are organized in El Salvador, while Mr. Devasini is an Italian citizen.
• Structural Update: The amendment reflects the re-domiciliation of the Tether entities from the British Virgin Islands to El Salvador and consolidates prior 12 amendments filed between Aug-2024 and Jun-2025.

Item 1 confirms the security (AGRO common shares) and issuer details; Item 5 reiterates the aggregate holding and states no other persons have an economic interest. The filing includes Schedule B (open-market purchases) but the transaction details are not provided in the excerpt.

In essence, the document formalizes Tether’s controlling position in Adecoagro, providing updated legal and ownership information but does not state any change in investment intent or new transactions.

Insights

Securities Analyst

TL;DR: Filing confirms Tether group’s 72.4 % controlling stake in AGRO; no new purchase details disclosed, but majority control is now formally documented.

The amendment crystallises that Tether Holdings and its subsidiary own over two-thirds of Adecoagro’s equity, translating into effective control of shareholder votes and corporate decisions. While this does not entail fresh capital inflow or operational guidance, it is material for valuation models that incorporate control premiums, float calculations and takeover protections. No intentions to acquire additional shares or to dispose are communicated, keeping outlook neutral. Investors should note that with such concentration, future governance and liquidity dynamics hinge largely on Tether’s objectives.

Corporate Governance Specialist

TL;DR: Majority ownership disclosure raises governance concentration issues but presents no explicit corporate action; impact classified as neutral yet highly noteworthy.

A single shareholder group now wields >70 % of voting power, satisfying "control" in most jurisdictions. Minority investors may experience reduced influence on board matters, strategic direction and potential related-party transactions. However, the filing neither proposes a squeeze-out nor signals governance changes. Because the amendment merely restates ownership and legal domicile, without altering rights or protections, I view immediate market impact as informational, not transactional. Ongoing monitoring of any subsequent tender offers or charter amendments is advised.
