11-K
Annual Report Classification · 70% confidence The document is SEC Form 11-K, an annual report containing full audited financial statements for an employee benefit plan (Telephone and Data Systems, Inc. Tax-Deferred Savings Plan) for the year ended December 31, 2025. It is not a brief announcement or certification but the actual comprehensive annual report with audit opinion, balance sheets, statements of changes, notes, and schedules. While our taxonomy does not have a separate code for Form 11-K, the closest match for a full annual report is the Annual Report category (10-K). FY 2025
2026-06-02 English
8-K
Regulatory Filings Classification · 25% confidence The document is a Form 8-K current report filed with the SEC, disclosing (i) the completion of the sale of spectrum assets and (ii) declaration of a special cash dividend. It is not a full annual or interim report, nor a management discussion, earnings release, or a specialized M&A proxy or tender‐offer document. It also is not a standalone dividend notice (even though it includes a dividend declaration, the primary filing is the 8-K). None of the other specific categories match an asset sale notification in a Form 8-K. Therefore, this falls into the fallback “Regulatory Filings” category (RNS).
2026-06-01 English
8-K
Declaration of Voting Results & Voting Rights Announcements Classification · 94% confidence The document is a Form 8-K current report containing Item 5.07 “Submission of Matters to a Vote of Security Holders” with detailed voting results for director elections and proposals. This corresponds to reporting official shareholder vote results from the Annual Meeting. Under the defined categories, this matches “Declaration of Voting Results & Voting Rights Announcements” (Code: DVA).

8-K - TELEPHONE & DATA SYSTEMS INC /DE/ (0001051512) (Filer)
Report Publication Announcement Classification · 96% confidence The document is a Form 8-K reporting that the company “issued a news release announcing its results of operations… A copy of the news release is attached hereto as Exhibit 99.1.” It is under 5,000 characters and only states that the earnings press release is attached, without including the actual financial data. Under the “menu vs. meal” rule, this is an announcement of the publication of a report rather than the report itself. Therefore, it is classified as a Report Publication Announcement (RPA).
2026-05-08 English
8-K - TELEPHONE & DATA SYSTEMS INC /DE/ (0001051512) (Filer)
M&A Activity Classification · 87% confidence The document is a Form 8-K reporting an M&A proposal under Item 8.01 “Other Events,” disclosing that TDS submitted a merger proposal and filed written communications pursuant to Rule 425. It explicitly includes merger communications (press release and proposal letter) as Exhibits 99.1 and 99.2, matching the description of merger/acquisition filings such as Form 425. Therefore, it is classified as a Merger & Acquisition filing (MA).
