AvalonBay Merger Closes Monday: AVB Holders Get a 10% Raise

Update (August 17, 2026, After the Close): The Merger Closed. AVB's Final Print Left a Gap.

The merger completed as scheduled Monday. Vivmark Residential begins trading as VMRK at Tuesday's open, per the completion announcement: roughly $51 billion of equity value, $70 billion of enterprise value, and more than 184,000 apartments, in line with what this piece estimated ahead of the close.

AVB's last print closed unchanged at $184.06, per matching quotes from stockanalysis.com, Investing.com and Google Finance, all three showing the same $182.74-$185.62 day's range. EQR closed down 3.50% to $63.66. That leaves 2.793 x $63.66 = $177.85 of conversion value under a $184.06 print, a $6.21, or 3.5%, gap in AVB's favor at the close, the opposite side of the 0.10% discount this piece flagged Friday.

That is a real, sourced number, and it is a strange one for a deal that priced itself down to a dime three sessions ago. The likeliest explanation is thin closing liquidity in a stock making its last print before delisting rather than a mispriced merger, and no live bid-ask could be sourced to confirm the spread was actually tradable in size. The merger-arb pass logged Friday is graded on the settled numbers regardless: a spread this size, whatever its cause, was the kind of edge the pass said would not be there. That call is marked a loss in the ledger below, with the execution caveat stated plainly rather than smoothed over.

TL;DR

• The merger closes Monday, August 17, and the combined company trades on the NYSE as VMRK from Tuesday's open, per the August 12 8-K. Monday should be AVB's last session.
• Each AVB share converts into 2.793 Vivmark shares. No cash, no election, nothing for a holder to do.
• AVB closed Friday at $184.06. The 2.793 shares behind it were worth $184.25 at EQR's $65.97 close, so the market is paying 99.9% of conversion value with one session left.
• The income goes up 10.2%. AVB pays $1.78 a quarter, or $7.12 a year. Vivmark starts at an annualised $2.81, and 2.793 of those is $7.85.
• Shareholders approved it on August 12 with more than 99% of votes cast on both sides. This one is finished; the interesting part is what an AVB holder wakes up owning.

When Does the AvalonBay Merger Close?

Monday, August 17, subject to customary closing conditions. Equity Residential and AvalonBay said so in a joint release on August 12, filed the same day on Form 8-K, after both shareholder bases approved every required proposal. More than 99% of votes cast went in favour at each meeting, on turnout of roughly 90% of shares outstanding.

The combined company takes the name Vivmark Residential and starts trading under VMRK at the open on Tuesday, August 18. Neither company has published a separate notice for AVB's final tape, so read Monday as the last AvalonBay session rather than a confirmed one.

The Board

Two closes, one ratio, and a nineteen-cent gap where the arbitrage used to be.

What Each AVB Share Converts Into

2.793 shares of Vivmark. That number was fixed when the deal was announced on May 21 and has not moved since, which means AVB holders have been carrying EQR's price risk for three months whether they framed it that way or not.

Run it against Friday's closes. EQR at $65.97, times 2.793, is $184.25. AVB closed at $184.06. Nineteen cents, or 0.10%, and it sits on the wrong side: the market marks AVB fractionally below what it converts into.

That gap is smaller than the round-trip cost of setting the trade up, and it is one session from expiring. I read it as a deal the market treats as done, priced by people who long ago stopped charging anything for the risk it breaks.

A 10% Raise, Arriving Tuesday

Here is the part worth doing on the back of an envelope, because it is the one number a holder actually feels.

AvalonBay pays $1.78 a quarter, $7.12 annualised, a 3.87% yield on Friday's close. Equity Residential pays $0.7025 a quarter, $2.81 annualised, 4.26%. The companies guided Vivmark's initial annualised dividend at that same $2.81, matching EQR's rate.

So an AVB share yielding 3.87% turns into 2.793 shares yielding 4.26%, at 99.9% of market value. Multiply out: 2.793 x $2.81 = $7.85 of annual income where $7.12 used to be. Call it +10.2%, arriving on Tuesday morning, with no decision required.

I want to be careful about how far that goes. It is a swap into a higher-yielding stock at parity, not new cash flow appearing from anywhere, and the guided rate is a board's stated intention rather than a declared dividend. But it is real, it is checkable, and I have not seen anyone put the arithmetic on a page.

Why Reddit Is Involved

AvalonBay's S&P 500 seat is being taken by Reddit before Tuesday's open, which is most of why RDDT closed up 12.63% on Friday. The framing in a lot of Friday's coverage had AvalonBay dropping out of the index. It is being absorbed.

Vivmark keeps the index membership on the Equity Residential side of the ledger, so the trackers holding AVB do not have to liquidate anything: their shares convert like everyone else's. The forced buying this week is entirely Reddit's, and I said what I thought of paying up for it on Friday. The index needed one new constituent because 500 is 500.

What Vivmark Actually Is on Tuesday

More than 180,000 apartments across 300-plus properties, roughly $53 billion of equity value and $71 billion of enterprise value at the companies' July 30 marks. Ben Schall runs it from AvalonBay, Steve Sterrett chairs it from Equity Residential, and it keeps two headquarters, Arlington and Chicago. Former AVB holders own 51.2%.

Those dollar figures move with the tape, and they already have: the same release put equity value near $52bn and enterprise value near $69bn in May. Multiplying Friday's closes gives about $51.8bn of combined equity today. Quote the 180,000 apartments if you want a figure that survives the week.

The case against getting excited: management guided $175m of gross synergies and $125m net after property tax reassessment. Spread across roughly 785m pro forma shares, that is about $0.16 a share a year, next to a $2.81 dividend. Cost savings are not why anyone should own this. Two coastal apartment books with overlapping markets and one G&A line is a sensible piece of housekeeping, and it is priced as one.

The Options Angle

The merger-arb trade is arithmetic, and the arithmetic says no. Long AVB at $184.06 against short 2.793 EQR at $65.97 locks in negative nineteen cents before commissions, and the position has one day to live. Nobody is getting paid to hold this.

The chain itself is the thing to watch out for. In an all-stock merger, outstanding options on the disappearing name get adjusted to deliver the new shares rather than cash out, which turns a standard AVB contract into a non-standard deliverable in VMRK. I have not seen the adjustment memo, so I am not quoting the terms. Anyone holding AVB paper into Monday's bell should read it before assuming their strike still means what it used to.

The One-Line Read

AvalonBay's last session is Monday. Holders do nothing, wake up Tuesday with 2.793 shares of Vivmark, and collect 10.2% more income on the same money. Rarely does a merger ask so little.
