Adient's board adopted a Tax Benefits Preservation Plan to help protect its U.S. net operating loss carryforwards and other tax attributes, and increased its share repurchase authorization by $400 million to a total of $1 billion. The rights plan is designed to make it harder for any person or group to reach a 4.95% stake, which could limit a takeover or large holder purchase, while the larger buyback authorization gives the company more capacity to return capital to shareholders.
The company's rights are issued one per ordinary share, exercisable after the Separation Time for $83.50 to buy one one-thousandth of a participating preferred share.
The repurchase authorization rises by $400 million to $1 billion total, with $435 million remaining after $565 million repurchased under the program launched in November 2022.
The plan expires on November 4, 2027 unless shareholders ratify it, in which case it runs to November 4, 2029; the company intends to seek shareholder approval at its next annual meeting.

Frequently asked questions
Which filings get a brief?
Form 8-K filings by S&P 500, MidCap 400 and SmallCap 600 companies that report a material event: results (Item 2.02), deals (1.01, 2.01), executive changes (5.02), restructuring (2.05), impairments (2.06), delisting notices (3.01), restatements (4.02), cybersecurity incidents (1.05), bankruptcy (1.03) and Regulation FD or other events (7.01, 8.01). Routine filings such as vote results or exhibits only are skipped.
How is the impact score set?
The model rates each filing from 1 (routine) to 5 (major, such as a merger, bankruptcy or restatement) based only on what the filing says. It is a reading aid for sorting the day's filings, not a prediction of how the stock will move.
How quickly do briefs appear?
The SEC filing feed is checked every hour on weekdays between 7 am and 9 pm Eastern; briefs follow within that hour or, when many filings arrive at once, after a batch completes later the same day.
Are older briefs kept?
Yes. This page shows the last 45 days, but every brief ever published stays online: each has its own page, and each company has an 8-K page listing all of its briefs, newest first, linked from its stock page and from the A-Z list of companies.
