Altera is a semiconductor company that designs field programmable gate arrays and the software and development tools that go with them, selling programmable logic into data centre, communications, industrial, automotive, aerospace and defence systems. Founded in 1983 in San Jose, California, it pioneered the commercial FPGA and was bought by Intel for $16.7 billion in 2015, running for most of the following decade as Intel's Programmable Solutions Group before being re-established as a separate company under its old name in 2024. Silver Lake agreed in April 2025 to buy 51 percent of the business at an $8.75 billion valuation, with Intel keeping the rest, and the deal closed on 15 September 2025, making Altera the largest standalone FPGA supplier. Revenue was $1.54 billion in 2024, with a GAAP operating loss of $615 million.

Altera Corporation files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Intel Announces Strategic Investment by Silver Lake in Altera (Intel investor relations, April 2025), Why Did Silver Lake Buy A Majority Stake In Intel's Altera FPGA Business? (The Next Platform) and Altera (Wikipedia). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- Intel Corporation, as of 27 Jun 2026. Share count not disclosed; Intel reports only the 49 percent interest and the carrying value. The $3.2 billion figure is specifically attributed to Altera by name (not a shared bucket total) and is unchanged between 27 December 2025 and 27 June 2026 per the Q2 FY2026 10-Q. sourcesource 2
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Altera Corporation where a holder stated one, and are missing where no holder did.
