RESEARCH — THE FILING TAPE #35

Four of 83: Berkshire Hathaway Exited Constellation Brands in Q2, and the Cohort Cut 16.5%

October 9, 2026

GetCoattail Research — Constellation Brands sells Corona, Modelo and Pacifico in the United States, and its October 6 earnings beat on both lines while its full-year outlook landed below what the Street wanted. Seventeen analysts rated the stock in the three days that followed. The filings describe a register that was already leaving: four of our 83 superinvestors still hold it, Berkshire Hathaway exited its last 632,890 shares in the June quarter, and the tracked cohort cut 16.47% of its shares in a quarter when the price fell 7.3%.

Start with the narrative: the quarter, reported after the close on Tuesday, October 6, was better than expected on its face — comparable earnings of $3.74 per share, up 3% from $3.63 a year earlier and ahead of the $3.60 estimate TipRanks aggregates, on revenue of $2.63 billion that also beat estimates and rose 6.1% year over year, according to Zacks. What the same coverage flagged was the outlook: the company's full-year earnings view fell short of Wall Street expectations. TipRanks counted 17 analyst ratings in the 72 hours to October 9 — third on its trending list, behind Zscaler and Marvell, the two audits this series published immediately before this one — with a Moderate Buy consensus and an average price target of $154.47, implying about 24.9% upside. It was the highest-ranked stock we had not yet audited. Our own price file, which ends October 2, adds a colder context the earnings coverage sits on top of: the last close in the file, $112.87, sits 0.1% above the 252-session closing low of $112.77 set on September 29, and 32.3% below the 252-session closing high of $166.68 set on February 4.

Now the filings. For Constellation Brands — the thirty-fifth Filing Tape audit — the story is a slow register getting slower at the tracked scale: the cohort shrank from seven holders to four, its largest historical name walked away from a position it had already cut by 95% on the 5% register, and the insider record is one of the quietest in this series.

Lens 1: the superinvestors — four holders, 3,786,298 shares, and a Berkshire exit

We track 83 large, mostly long-only managers whose 13F portfolios we collect directly from SEC EDGAR. As of June 30, 2026, 4 held Constellation Brands long — no option rows — totalling 3,786,298 shares worth $526,636,195. The direction count is two decreased and two increased: no new positions, no unchanged rows.

The largest holder is Bill Nygren's Oakmark Funds, at 3,097,056 shares worth $430,769,525, a 0.57% portfolio weight, cut 4.2% in the quarter — and, of a four-name register, 81.8% of the tracked cohort's Constellation shares. Behind it: Richard Pzena's Pzena Investment Management at 599,314 shares worth $83,358,584 (0.24% weight, increased 0.6%), David Katz's Matrix Asset Advisors at 74,277 shares worth $10,331,188 (0.84% weight, increased 60.5%), and Hillman Capital Management at 15,651 shares worth $2,176,898 (1.58% weight, decreased 16.7%). A quarter earlier the pipeline's CUSIP file held seven rows totalling 4,533,061 shares. Three of those rows are gone: Warren Buffett's Berkshire Hathaway exited all 632,890 shares (prior reported value $94,933,500), Lee Ainslie's Maverick Capital exited 2,373 shares, and Mason Hawkins's Southeastern Asset Management exited 3,661 shares — each exit appears in the EDGAR collection's exit lists at exactly the share count and prior value of its first-quarter row. The cohort total moved from 4,533,061 to 3,786,298 shares, a change of −16.47%, a difference of −746,763 shares, in a quarter when the price fell from $150.00 at March 31 to $139.09 at June 30, a change of −7.3%. The cohort's reported value implies $139.09 per share, matching the June 30 close exactly. Berkshire's exit alone accounts for 632,890 of the 746,763 shares the cohort shed.

Lens 2: institutions — 1,029 filers, shares up 14.72%

Zoom out to the whole 13F market and the quarter looks different. At June 30, 2026, 1,029 institutions reported positions, down one from 1,030 at March 31 (−0.10%), and 1,026 reported long positions. Reported shares rose 14.72%, from 124,313,264 to 142,617,463 shares. Reported aggregate value rose 7.34% to $20,338,030,398; the aggregate includes option rows, so we headline filer and share counts and label dollars "reported" (see methodology). The implied value per share, $142.61, sits 2.5% above the June 30 close of $139.09. Set the two registers side by side and the contrast is the quarter: filer count essentially flat, reported shares up 18,304,199, while the tracked cohort shed 746,763 shares and lost three of its seven holders — the broad market absorbed shares in size without adding filers, and the tracked names left anyway.

Lens 3: the 5% register — eleven filings, and Berkshire's 13.4 million shares became 632,890

Our full parse holds eleven SC 13D/G filings for Constellation Brands — three SC 13G originals and eight SC 13G/A amendments, ten reporting-person names, the most recent filed May 15, 2026, and no SC 13D originals at all. Six of those names are one group: Warren E. Buffett, Berkshire Hathaway Inc., National Indemnity Company, GEICO Corporation, Government Employees Insurance Company and the Precision Castparts Corp. Master Trust co-report the same position, so the register holds five reporting groups. That group's rows run 12,009,000 shares (6.6%) as of March 31, 2025, up to 13,400,000 shares (7.6%) as of September 30, 2025, then down to 632,890 shares (0.4%) as of March 31, 2026 — the register's latest filing, submitted May 15, 2026. Read against Lens 1, the two filings tell one story in two acts: the 13G register shows the Berkshire group cutting 95% of its stake between September and March, and the tracked 13F register then shows the remaining 632,890 shares — the exact share count in both records — gone entirely in the June quarter. The Vanguard Group reported 18,417,534 shares (10.19%) as of March 31, 2025, then 0 shares (0.0%) as of March 13, 2026 — and a separate Vanguard entity, Vanguard Capital Management, then printed 10,490,856 shares (6.05%) as of March 31, 2026. Capital World Investors printed 12,864,887 shares (7.1%) as of March 31, 2025, then 6,781,286 shares (3.8%) as of September 30, 2025, then 12,494,131 shares (7.2%) as of March 31, 2026. Capital International Investors holds a single row of 4,240,201 shares (2.3%) as of December 31, 2024. We report rows as filed and never sum them: the aggregation's total across these rows would add different dates together, count the Berkshire position six times through its co-reporting, and multiply-count overlapping passive stakes.

Lens 4: insiders — three purchases in the record, none by an officer, none in the last year

The parsed Form 4 record holds 98 filings through October 2, 2026. Across it, open-market purchases total 3 transactions — 3,000 shares, $527,276.10, two buyers — and none of the three is recorded as an officer purchase. Against that stand 5 sales totalling 10,933 shares and $1,757,083.81, by three sellers, four of them recorded as officer sales. The last year holds zero purchases against 3 sales of 6,962 shares for $1,024,433.81 by three sellers, two of them recorded as officer sales. The last 90 days are quieter still: across 23 filings there is not one open-market purchase and not one open-market sale — no P-code and no S-code transactions at all. One sourcing note deserves its own sentence rather than a footnote: our site's insider aggregate carries no Constellation Brands row at all, so unlike several earlier audits there is no second aggregate to cross-check here; every insider figure in this audit comes from the full parse alone, and we say so rather than implying a match. We assign no motives to any of it; the record's shape is the fact — this is a small, two-sided register that has printed nothing at all for a quarter.

Lens 5: Congress — two sales, no purchases, House only

Across the congressional record we maintain (combined record as of October 3, 2026), Constellation Brands shows 0 purchase transactions and 2 sale transactions, with no purchase on record. The House aggregate (as of October 3, 2026) carries the identical record — both sales are House rows. The Senate aggregate (as of October 1, 2026) carries no Constellation Brands record. The combined aggregate records a member count of zero alongside those two sales, so this audit cites transaction counts only and makes no claim about how many members traded. Congressional disclosures report value ranges rather than exact amounts, so this lens records direction and counts only. It is a two-transaction register: sales only, one chamber only.

Lens 6: short interest — 8,516,727 shares, up 12.5% since the June settlement

As of September 15, 2026 — the most recent FINRA settlement date — 8,516,727 Constellation Brands shares were sold short, with days-to-cover of 3.44, up 4.17% from the prior settlement. The full-series peak is recent: 10,918,197 shares on October 31, 2025, so the latest reading sits 22.0% below the peak. Year over year the borrow is nearly unchanged, up 4.0% from 8,185,499 shares on September 15, 2025, but since the June 30 settlement (7,572,909 shares) it is up 12.5% — the borrow rebuilt over the same summer the price fell 18.9% from its June 30 close. Our fundamentals file carries no share count for this name (see methodology), so we do not express the borrow as a percentage of shares outstanding rather than estimating one.

Short interest in Constellation Brands
Chart 2: Shares sold short in Constellation Brands at each FINRA biweekly settlement, Jan 2024 – Sep 15, 2026 (n = 65 settlements in the chart window; the full collected series runs 137 settlements from Jan 15, 2021). The series maximum, 10,918,197 shares on Oct 31, 2025, sits inside the window. The latest reading, 8,516,727 shares on Sep 15, 2026, is 22.0% below that peak, 4.0% above the 8,185,499 shares recorded on Sep 15, 2025, and up 4.17% from the prior settlement. Source: FINRA Equity Short Interest files; GetCoattail collection (stz_short_interest_series.csv).

The recent settlements run 8,254,203 on July 15, then 9,178,065, 7,391,267, 8,176,016 and 8,516,727 — a borrow oscillating in a band it has occupied for a year. The series began at 3,149,911 shares on January 15, 2021; its lowest reading, 1,186,460 shares, came on October 31, 2023. What changed in 2026 is not the level so much as the direction since June: up 12.5% across five settlements while the closing price fell from $139.09 to $112.87.

The gap, stated plainly

The registers describe a company whose October earnings beat arrived after its tracked ownership had already thinned. The tracked superinvestors held 3,786,298 shares at June 30 — four holders, one of them 81.8% of the total — having cut 16.47% in a quarter when the price fell 7.3%, with Berkshire Hathaway's exit of 632,890 shares accounting for most of the shares shed. The full market moved the other way on shares, up 18,304,199 to 142,617,463, on an unchanged filer count of about a thousand. The 5% register printed eleven filings: the Berkshire group fell from 13,400,000 shares (7.6%) to 632,890 (0.4%) before its 13F exit, one Vanguard row went to zero and another appeared, and Capital World's stake halved and then roughly doubled back. Insiders bought three times in the parsed record — $527,276.10 in total, none of it by an officer, none of it in the last year — against $1,757,083.81 of sales, and printed no open-market transaction at all in the last 90 days. Congress registers two sales and no purchases, all in the House. And the borrow, at 8,516,727 shares, is up 12.5% since the June settlement and almost exactly where it sat a year ago. One plausible reading is that the registers are sorted by mandate and by clock: the tracked managers and the largest 5% holder spent a year reducing a position the broad benchmark market kept absorbing, insiders and Congress barely trade this name at all, and the October story belongs to none of them yet, because none of these filings can see October. The record supports each clause separately; it does not say which register is right.

What would change the picture

Nothing above is a recommendation. It is a record. These are the filings that would change the description:

Until one of those prints, the record describes a stock held by four of our 83 tracked superinvestors — 3,786,298 shares after a 16.47% one-quarter cut and a complete Berkshire Hathaway exit — whose full market added 14.7% more reported shares in the same quarter, whose insiders have bought $527,276.10 against $1,757,083.81 of sales with no transaction at all in 90 days, whose congressional register shows two sales and no purchases, and whose borrow has rebuilt 12.5% since June while the price fell to the edge of its 252-session low.
