onsemi Restructures Synaptics Acquisition as All-Cash Deal to Eliminate Share Dilution

onsemi restructured its acquisition of Synaptics into a $5.7 billion all-cash transaction at $123 per share, replacing the original stock-based agreement after Synaptics received a competing proposal. The revised structure eliminates shareholder dilution and is now expected to immediately boost adjusted earnings per share upon closing, compared to an 18-month path to accretion under the previous terms. The acquisition will expand onsemi's capabilities in edge artificial intelligence, connectivity, and human-machine interfaces while adding debt to the company's balance sheet.

onsemi's decision to restructure the Synaptics acquisition into a cash-funded deal fundamentally altered the financial mechanics of the transaction. The original June announcement used a stock-swap formula that lost value as onsemi's share price declined, pushing the deal's value down to $5.7 billion from approximately $7 billion. By fixing the per-share price at $123 in cash, the company eliminated the need to issue new equity to current shareholders while achieving immediate earnings accretion rather than waiting 18 months for financial benefits to materialize.

The competing bid for Synaptics prompted the board to reassess the deal's terms, ultimately accepting the revised structure despite increased debt on onsemi's balance sheet. The company will leverage existing cash reserves and secured term loans from Morgan Stanley to finance the acquisition, with management projecting leverage ratios below two times and committing to use future cash flow for debt reduction and share buybacks.
