Filing Released Lang Actions
8-K
Capital/Financing Update Classification · 85% confidence The document is an SEC Form 8-K Current Report under Item 8.01 “Other Events,” describing a corporate action to partially redeem €250 million of its senior unsecured notes due 2027 and the related make-whole premium. This is a change in the company’s debt capital structure (a redemption of outstanding notes). There is no involvement of share transactions or new share issues, nor is it merely an interest rate change; it is a financing/capital structure update. Therefore, the appropriate classification is a Capital/Financing Update (CAP).
2026-06-02 English
8-K
Capital/Financing Update Classification · 92% confidence The document is a Form 8-K current report under the Securities Exchange Act of 1934 describing the completion of a registered public offering of senior unsecured notes, detailing the terms of the new debt issuance, use of proceeds, and related indenture agreements. It is neither an earnings release nor an annual or interim report, but rather an update on the company’s financing activities and capital structure. Therefore, it falls under the Capital/Financing Update category.
2026-05-27 English
S-8
Share Issue/Capital Change Classification · 88% confidence The document is a Form S-8 registration statement filed with the SEC under the Securities Act of 1933 to register 12,000,000 shares for issuance under an equity incentive plan (the American Tower Corporation 2026 Equity Incentive Plan). This is not a full operating or financial report (10-K, 10-Q), management discussion, call transcript, or dividend notice. It specifically registers new shares for issuance, which constitutes a change in the company’s capital structure. Therefore, it falls under the Share Issue/Capital Change category (Code: SHA).
2026-05-26 English
8-K
Regulatory Filings Classification · 89% confidence The document is a Form 8-K current report filed under the Securities Exchange Act (SECUREX). It announces corporate governance changes (Item 5.02), stockholder vote results (Item 5.07), an equity plan adoption, and other regulatory disclosures. It is not a full annual or interim report, earnings release, proxy statement, or other specialized filing. Therefore it falls into the general Regulatory Filings category.
2026-05-21 English
424B2
Capital/Financing Update Classification · 90% confidence The document is an offering prospectus supplement and accompanying prospectus for a €750 million senior notes debt issuance by American Tower Corporation. It details the terms of the notes, underwriting, redemption, use of proceeds, and listing plans, representing a capital markets financing transaction. This falls squarely under “Capital/Financing Update” (CAP) as it relates to company fundraising and capital structure changes.
2026-05-20 English
8-K
Capital/Financing Update Classification · 88% confidence The document is a Form 8-K current report describing the pricing of a registered public offering of senior unsecured notes (750 million euros of 4.000% notes due 2033). This clearly constitutes a financing activity update rather than an earnings release or management discussion. It is not merely an announcement of a report, nor is it an interest rate change notice or an M&A transaction. It fits squarely into “Capital/Financing Update” (CAP).
