Infineon announced in June 2019 that it would buy Cypress Semiconductor for $23.85 in cash per share, valuing the deal at €9.0 billion on a fully diluted enterprise-value basis. The acquisition closed on April 16, 2020. The “$10 billion” label is a rounded description—not the exact figure used in the announcement or the closing filing.
What Infineon agreed to pay
Under the agreement announced June 3, 2019, Infineon offered $23.85 in cash for each Cypress share. The companies described the transaction as having a fully diluted enterprise value of €9.0 billion. Infineon said the offer represented a 46% premium to Cypress’s unaffected 30-day volume-weighted average share price. The premium compares the offer price with that specific pre-announcement trading benchmark; it is not a measure of the transaction’s total value.
These measures describe different things. The €9.0 billion figure was enterprise value, while Cypress’s 2020 SEC closing filing recorded approximately $8.946 billion in aggregate per-share merger consideration paid to stockholders. The figures use different currencies and valuation concepts, so they are not competing estimates of the same total. “$10 billion” is a rounded headline shorthand, not the precise announced enterprise value or the SEC-reported stockholder consideration.
Infineon and Cypress’s June 3, 2019 announcement gives the offer terms and enterprise value; the SEC Form 8-K filed at closing reports the aggregate stockholder consideration.

Why Infineon wanted Cypress
Infineon presented Cypress as a complementary addition to its portfolio, particularly for automotive, industrial, and Internet of Things markets. Its stated strategy was to combine semiconductor products and capabilities to offer customers a broader set of hardware and software solutions linking the “real” and digital worlds. Infineon CEO Reinhard Ploss described the acquisition as a “Landmark step in Infineon’s strategic development” and said it would enable a more comprehensive portfolio.
At announcement, the companies said the combination would have had €10 billion in 2018 revenue on a pro forma basis and projected that it would make Infineon the world’s eighth-largest chip manufacturer. Those were announcement-era company figures and a projected ranking, not a description of current revenue or rank.

What the synergy figures meant
Infineon and Cypress forecast €180 million in annual cost synergies by 2022 and more than €1.5 billion in annual revenue synergies over the long term. These were management projections announced in 2019. They should not be read as confirmed savings or revenue achieved: the cited deal announcement states targets, not realized results.
