Tender and Support Agreement legal

"Tender and Support Agreement, dated as of May 13, 2026, by and between Zydus Worldwide DMCC"

Letter of Transmittal regulatory

"Letter of Transmittal is attached as Exhibit (a)(1)(B)"

A letter of transmittal is a written form investors use when sending physical stock certificates or electronic ownership documents to a company or its agent to surrender shares, tender them in an offer, or claim payment or replacement securities. It acts like a packing slip that lists what is enclosed, gives instructions on how the transfer should be handled, and provides proof of the transaction—important for ensuring investors receive the correct payment or new securities without delay or dispute.

Offer to Purchase regulatory

"Offer to Purchase, dated May 18, 2026, attached as Exhibit (a)(1)(A)"

An offer to purchase is a formal proposal from one party to buy a specific amount of shares or assets from another party at a set price. It matters to investors because it signals interest in acquiring ownership and can influence the value or control of a company. Think of it as someone putting forward a clear, serious offer to buy something they find valuable.
