Apple's $0.27 quarterly dividend records Monday (T-3) and pays Wednesday May 14 (T-6) under the $100 billion buyback authorization the board approved April 30 alongside record March-quarter revenue of $111.2 billion. [1] [2] Berkshire Hathaway's Q1 2026 13F filing — which discloses changes to a $274.16 billion equity book where Apple still represents roughly $130 billion at about 35% of the disclosed portfolio — is due May 15 (T-7). [3] The paper's Thursday brief on the cohort 13F watch framed the week as the disciplined cohort's only execution window against the Mag-7 capex regime.

The structural reads stack: Berkshire entered Q1 with cash reserves above $397 billion against a 42-position equity book, Apple's authorization adds $100 billion to a buyback program that has already retired roughly $740 billion of stock since 2012, Pfizer is at zero buybacks for FY26, and the Mag-7 cohort committed $115–135 billion in 2026 AI capex. [3]

Two filings, four days apart, on one balance sheet's worth of capital discipline — the 13F window will disclose whether Berkshire trimmed its Apple position further in Q1 (after the 2025 reductions from 905 million shares to 300 million) or held the line at roughly 35% of the equity book, with May 11 recording Apple's dividend, May 14 paying it, and May 15 printing the cohort.
